UE Capability in a Nutshell

UE Capability in Detail

The purpose (Function) of UE Capability Information in NR is same as LTE UE Capability Information. In LTE UE capability information carries the information in roughly two large category : RF/Physical layer information and Feature Group(FGI). NR also reports similar information (i.e, RF/PHY information and Feature sets) but much more diverse information than LTE.

For the details of the meaning of each IEs listed here, refer to 38.306. But to understand the exact meaning of the descriptions in 38.306, you would need to understand the whole NR specification... simply put, it would be life time job to understand the full details of what you see in the UE capability information. So.. don't be hurry.. take time trying to one at a time.  The best way is to take a look at specific IEs that you are interested one at a time and find some examples as shown below and try to understand the detailed meaning based on 38.306 and all other related specification.

Why UE capability checking is important ?

In modern LTE and 5G networks, the UE Capability Enquiry and UE Capability Information procedures play a critical role in enabling seamless communication and optimal resource allocation between the User Equipment (UE) and the network. These processes allow the network to gather detailed information about the UE's supported features, including frequency bands, carrier aggregation capabilities, modulation schemes, and advanced functionalities like MIMO and beamforming. By understanding the UE's capabilities, the network can efficiently tailor its configurations, ensuring compatibility, maximizing performance, and enabling advanced features such as dynamic spectrum sharing and dual connectivity. Moreover, these procedures are essential for supporting interworking between multiple radio access technologies (RATs), like LTE, NR, and legacy networks, to provide uninterrupted service and superior user experience. Neglecting these processes can lead to underutilization of resources, degraded service quality, and potential interoperability challenges, underscoring their significance in modern telecommunications systems.

• Essential Role in Communication: UE Capability Enquiry and UE Capability Information procedures are vital for seamless communication and optimal resource allocation in LTE and 5G networks.
• Detailed Capability Assessment: These processes allow the network to gather information about the UE's supported features, such as frequency bands, carrier aggregation, modulation schemes, and advanced functionalities like MIMO and beamforming.
• Efficient Network Configuration: By understanding the UE's capabilities, the network can optimize configurations to ensure compatibility and maximize performance.
• Enablement of Advanced Features: They facilitate advanced functionalities like dynamic spectrum sharing, dual connectivity, and beam management.
• Inter-RAT Interoperability: These procedures are critical for smooth operation between multiple radio access technologies (RATs), such as LTE, NR, and legacy networks.
• Avoidance of Resource Wastage: Proper execution ensures efficient resource allocation and avoids issues like underutilization or misconfiguration.
• Enhanced User Experience: Ensures superior quality of service and uninterrupted network operation.

NOTE : One of the most frequent issues that I've heard of is 'I am trying to test my UE for this feature, but Network does not enable the feature'. In many of these cases, the root cause turned out to be because UE does not declaire the support of the feature in UE capability Information. If you have similar issue, my recommendation is to check UEcapability Information from your device.

Pitfalls of UE Capability Reporting

The UE Capability Enquiry and UE Capability Information procedures are critical for efficient network operations, but they are not without potential pitfalls. One significant challenge arises when a UE reports support for a capability during the capability information exchange, but in practice, the feature is either partially implemented or not functional in the real-world scenario. This discrepancy can lead to several issues:

• Network Misconfiguration
• The network may configure the UE for a feature it claims to support (e.g., carrier aggregation, high-order MIMO, or specific NR numerologies). However, if the UE's implementation of this feature is incomplete or non-functional, it can result in misaligned configurations. This can lead to session drops, failed handovers, or degraded service quality.
• Resource Wastage
• The network allocates resources, such as spectrum and scheduling grants, based on the UE's reported capabilities. If the UE cannot utilize these resources effectively, it wastes valuable network resources that could be allocated to other UEs.
• Service Interruptions
• Inaccurate capability reporting can cause interruptions in advanced services like VoLTE, VoNR, or carrier aggregation. For instance, if a UE reports support for 256QAM modulation but experiences errors when operating at higher modulation levels, it can degrade overall service performance.
• Interoperability Issues
• Networks often comprise equipment from multiple vendors. A mismatch between UE-reported capabilities and actual implementation can cause interoperability issues, particularly in features like dynamic spectrum sharing, dual connectivity, or beamforming, which rely on tight coordination between the UE and the network.
• Testing and Validation Gaps
• UEs sometimes pass compliance testing but fail in live network scenarios because the capability was not fully tested under diverse conditions. This gap between theoretical support and practical performance can lead to unexpected failures during deployment.
• Increased Troubleshooting Complexity
• Identifying and resolving issues caused by inaccurate UE capability reporting can be challenging. Network engineers must investigate whether the problem lies in the UE's implementation, network configurations, or an interaction between the two.
• Impact on QoS and User Experience
• When the network relies on false capability information, the quality of service (QoS) can be negatively impacted, leading to poor user experiences such as slower data rates, call drops, or inconsistent coverage.

Examples of Real-World Scenarios

• A UE may claim support for carrier aggregation but fail to handle specific inter-band combinations due to hardware limitations.
• A device might report support for advanced modulation schemes like 256QAM but lack the processing power to maintain acceptable error rates at higher modulation levels.
• UEs might advertise compatibility with certain 5G numerologies or bandwidths but struggle with power management, causing early battery drain or overheating.

High Level Categories of UE capability

UE capabilities can be broadly classified into two main categories: Radio capabilities and Supported features.

Radio capabilities encompass the physical layer characteristics of the device, such as the frequency bands and bandwidths it can operate on, the modulation schemes it supports, and its MIMO capabilities (i.e., the number of antennas it can use for transmitting and receiving data). This category also includes the device's power class, which determines the maximum power it can transmit, and its support for carrier aggregation, allowing it to combine multiple frequency bands for increased data rates.

Supported features delve into the device's capabilities beyond the physical layer, encompassing functionalities like support for specific network technologies (e.g., LTE, NR), data transmission protocols, and advanced features like positioning and location services. This category also includes information about the device's software and hardware capabilities, ensuring compatibility with the network's services and applications.

Essentially, these two categories together provide a comprehensive overview of the device's communication capabilities, enabling the network to optimize the connection and provide the best possible user experience.

Supported Maximum Data Rates

These capabilities are essential for the network to allocate resources effectively and ensure optimal data transfer for various applications, from basic web browsing to demanding real-time services.

Downlink (DL) and Uplink (UL) Maximum Data Rates

These indicate the peak data speeds the UE can achieve when receiving (DL) and transmitting (UL) data. These rates are influenced by factors like the UE's category, supported modulation schemes, and MIMO capabilities. Higher data rates allow for faster downloads, smoother streaming, and quicker uploads.

• Key Parameters for DL and UL Data Rates:
• MaxDLDataRate: The maximum data rate for the downlink.
• MaxULDataRate: The maximum data rate for the uplink.

Sidelink (SL) Maximum Data Rates

This specifies the maximum data rate for direct communication between UEs, bypassing the base station. Sidelink communication is crucial for proximity services like vehicle-to-everything (V2X) communication and public safety applications.

• Key Parameters for SL Data Rates:
• MaxSLtxDataRate: Maximum sidelink transmission data rate.
• MaxSLrxDataRate: Maximum sidelink reception data rate.

Total Layer 2 Buffer Size for DL/UL and Sidelink

The total Layer 2 (L2) buffer size refers to the amount of data the UE can store in the RLC and PDCP layers during transmission and reception. It ensures efficient handling of data across multiple bearers.

• Key Parameters:
• MaxDLDataRate and MaxULDataRate: Used to determine the buffer size for DL and UL.
• MaxSLtxDataRate and MaxSLrxDataRate: Used for sidelink buffer size.
• RLC RTT (Round Trip Time): Delay values for RLC processing, dependent on numerology and frequency range.
• X2/Xn delay + Queuing: Network-side delay assumptions:
• 25ms if NR is the Secondary Cell Group (SCG).
• 55ms if EUTRA is the SCG.

General UE Capability Parameters

The General UE Capability Parameters define the key features that allow a UE to work efficiently with the network in NR (New Radio) systems. These parameters include support for power-saving modes, handling multiple carriers, managing mobility, and optimizing performance for tasks like delay reporting and paging. They also enable the UE to communicate its capabilities, such as bandwidth, MIMO preferences, and overheating management, helping the network provide better performance and energy efficiency. These parameters ensure the UE can integrate smoothly into 5G networks and deliver a reliable user experience.

PDCP Parameters

PDCP (Packet Data Convergence Protocol) parameters define how data is processed, compressed, and managed over the 5G NR radio interface. They address aspects such as header compression (for both Ethernet and IP-based traffic), security features like ciphering and integrity protection, and advanced capabilities like PDCP duplication and Uplink Data Compression (UDC). These parameters ensure that data can be delivered efficiently and reliably, adapt to diverse network requirements, and maintain service quality across various deployment scenarios.

Key points include:

• Header Compression: Defines mechanisms (e.g., ROHC, EHC) to reduce overhead for IP and Ethernet packets.
• Security Functions: Manages ciphering and integrity protection for user data.
• PDCP Duplication: Provides robust data delivery by replicating packets across multiple RLC entities.
• PDCP Discard Timers: Governs how long data can be buffered before being dropped.
• Uplink Data Compression: Optimizes bandwidth usage for uplink traffic through dictionary-based compression.

These parameters collectively enable PDCP to balance reliability, bandwidth efficiency, and latency, ensuring a high-quality user experience in 5G NR networks.

MAC parameters

The MAC (Medium Access Control) parameters control how user equipment (UE) coordinates with the physical layer to transmit and receive data over the air interface. They define mechanisms for resource scheduling, handling uplink grants, data prioritization, and DRX (Discontinuous Reception) cycles, enabling devices to optimize power usage and performance. By specifying how and when the UE can skip transmissions, activate secondary cells, or apply DRX operations, these parameters help tailor network behavior to diverse operational needs.

Key aspects include:

• Uplink Resource Allocation: Determines how the UE requests, schedules, and manages uplink grants to efficiently use available spectrum.
• DRX Configuration: Manages active and sleep cycles for reduced power consumption while maintaining acceptable latency.
• Data Prioritization: Allows the UE to prioritize traffic from different logical channels, ensuring critical data is sent first when grants overlap.
• Advanced SCell Activation: Enables quick activation or resumption of secondary cells for carrier aggregation or dual connectivity scenarios, boosting throughput.
• HARQ and Feedback Options: Regulates how the UE handles retransmissions, feedback, and certain specialized modes like disabled HARQ feedback in specific scenarios.

Physical layer parameters - BandCombinationList parameters

These band parameters define how user equipment (UE) manages different frequency bands, supports various carrier aggregation scenarios, and handles advanced features like DAPS handover and dynamic uplink transmission. By specifying combinations for EUTRA and NR, bandwidth classes, power classes, and sidelink coexistence, they enable the UE to operate efficiently across multiple radio technologies and frequency ranges.

Key points include:

• Band-Level Definitions: Specify which EUTRA and NR bands the UE supports, covering downlink and uplink frequencies.
• Carrier Aggregation Classes: Define how aggregated transmissions are configured (e.g., bandwidth classes and maximum component carriers).
• Multi-Band Operations: Enable NE-DC, EN-DC, or NR-DC by detailing how the UE can operate simultaneously across different radio access technologies and frequency bands.
• Advanced Features: Allow for dynamic UL Tx switching, SRS switching across bands, DAPS handover for seamless mobility, and power class constraints for maximizing transmission power.
• Sidelink Coexistence: Indicate how PC5-based sidelink communications can run in parallel with regular cellular (Uu) uplink/downlink transmissions.

Physical layer parameters - BandNR parameters

The BandNR parameters describe how a 5G NR UE declares its radio capabilities for specific NR bands. This information covers the frequency ranges (FR1 and FR2), duplex modes (FDD, TDD, and, if applicable, supplementary uplink or downlink), maximum supported bandwidths, subcarrier spacings, and MIMO layers per band. The UE signals which bands it supports, the maximum channel bandwidth available in each band, and key features such as partial bandwidth usage or SRS (Sounding Reference Signal) beam management. The specification also details advanced capabilities, including multi-TRP or multiple antenna panel support, beamforming techniques, and timing advance enhancements that address large delays in non-terrestrial network or mmWave scenarios. Overall, the BandNR parameters allow a network to understand the scope of a UE’s band-specific constraints, enabling optimized scheduling, carrier aggregation, and beam management according to each device’s physical-layer capabilities.

Below is a concise overview of the BandNR-related Physical layer parameters for 5G NR UE capabilities

BandNR Basics

• Band Identifiers (n#)
• NR bands are labeled as “nXX” (e.g., n1, n78, n257).
• Each band identifies a specific frequency range and duplex arrangement (FDD, TDD, SDL, SUL).
• Frequency Ranges
• FR1: ~410 MHz to 7.125 GHz
• FR2: ~24.25 GHz to 52.6 GHz
• Duplex Modes
• FDD (Frequency Division Duplex): Separate UL and DL carriers.
• TDD (Time Division Duplex): UL/DL share the same frequency but separated in time.
• SUL/SDL (Supplementary Uplink/Downlink): Additional carriers used in parallel with primary UL/DL.

Band-Specific Capability Signaling

• Supported Band Combinations
• UE signals each band (e.g., n1, n3, n78) it can operate on and whether it supports CA (Carrier Aggregation) across multiple bands.
• Indicates maximum aggregated bandwidth, number of component carriers, and possible MIMO layers per band or per combination.
• Max Supported Bandwidth per Band
• UE capability indicates the maximum RB (resource block) configuration or maximum channel bandwidth within each NR band.
• Supported Subcarrier Spacings
• For FR1: Typically 15 kHz, 30 kHz, (and possibly 60 kHz in certain higher sub-bands).
• For FR2: Typically 60 kHz, 120 kHz (some UEs may also support 240 kHz in certain scenarios).
• Maximum Transmission / Reception Layers
• Specifies how many MIMO layers a UE can handle for DL (e.g., 2-layer, 4-layer, 8-layer) and UL (typically fewer).

Selected Physical Layer/Radio RF Parameters

• Channel Bandwidth Sets
• 5G NR channel bandwidths differ by band and subcarrier spacing.
• For instance, FR1 might see maximum channel bandwidths of 50 MHz, 100 MHz, etc., depending on the band. FR2 can go up to 400 MHz or more.
• Power Classes
• For FR1: Commonly “PC3” (standard device) or “PC2” (higher power).
• For FR2: Definitions exist for various power classes (e.g., PC1, PC2, PC6 for certain mmWave or RedCap scenarios).
• Tx/Rx Antenna Configuration
• UE indicates how many Rx/Tx antennas it supports.
• Impacts maximum possible rank or MIMO layers.
• Supported Modulations
• Up to 256QAM in DL (FR1), 64QAM or 256QAM in UL (depending on band).
• FR2 UEs often indicate whether 256QAM is supported (less common).
• SRS (Sounding Reference Signal) / Beam Management
• Per-band info on how many SRS resources can be configured, partial frequency sounding, or beam-based SRS transmissions in FR2.
• Some advanced beam management parameters are signaled if the UE supports wideband or multiple-beam operations.

Advanced Feature Sup

• Multiple Panel Support / Multi-TRP
• If the UE supports advanced multi-TRP (transmission-reception-point) or multi-panel MIMO, it signals so in the band-specific capability.
• Rate Matching & Legacy CRS
• Some UEs indicate capabilities for rate-matching around LTE CRS in certain dynamic spectrum sharing deployments.
• Partial Frequency / Bandwidth Configurations
• UEs can support partial bandwidth usage, sub-band scheduling, or partial frequency sounding (especially relevant in FR1 for large bandwidths).
• Timing & TA (Timing Advance) Enhancements
• For NTN (Non-Terrestrial Networks) or advanced FR2 scenarios, UEs can indicate special timing offset or pre-compensation support to handle large delays.

}

38.306 specifies the meaning of this IE as follows :

 

channelBWs-DL/channelBWs-UL :

Indicates for each subcarrier spacing whether the UE supports channel bandwidthslower than the maximum channel bandwidth as defined in TS 38.101-1  and TS 38.101-2 . If this parameter is not included, it mean that the UE supports the channel bandwidths among [5, 10, 15, 20, 25, 30, 40, 50, 60, 80, 100] in FR1 and [50, 100, 200] in FR2.

 

For FR1, the bits starting from the leading / leftmost bit indicate 5, 10, 15, 20, 25, 30, 40, 50, 60 and 80MHz. For FR2, the bits starting from the leading / leftmost bit indicate 50, 100 and 200MHz.

 

NOTE : it is assumed that the maximum bandwidth (in most case 100Mhz in FR1 SCS30, 50 Mhz in FR1 SCS 15, 400 Mhz FR2) is supported by default.

              Example 14 : SA Supportablity

There is no direct indicator for SA support in UE capability Information (as far as I know). You may check the SA supportability using a NAS message as shown below. You can find this information from Attach Request in LTE and RegistrationRequest in NR SA

 

UE network capability:

  0xf0 (EEA0=1, 128-EEA1=1, 128-EEA2=1, 128-EEA3=1, EEA4=0, EEA5=0, EEA6=0, EEA7=0)

  0x70 (EIA0=0, 128-EIA1=1, 128-EIA2=1, 128-EIA3=1, EIA4=0, EIA5=0, EIA6=0, EIA7=0)

  0xc0 (UEA0=1, UEA1=1, UEA2=0, UEA3=0, UEA4=0, UEA5=0, UEA6=0, UEA7=0)

  0x40 (UCS2=0, UIA1=1, UIA2=0, UIA3=0, UIA4=0, UIA5=0, UIA6=0, UIA7=0)

  0x19 (ProSe-dd=0, ProSe=0, H.245-ASH=0, ACC-CSFB=1, LPP=1, LCS=0, 1xSRVCC=0, NF=1)

  0xb0 (15 bearers=1, SGC=0,N1mode=1, DCNR=1, CP backoff=0, RestrictEC=0, V2X PC5=0, multipleDRB=0)

 

Or you may indirectly confirm on SA supportability from LTE UE capability as below

 

irat-ParametersNR-v1540 {

 eutra-EPC-HO-ToNR-TDD-FR1-r15 supported,

 sa-NR-r15 supported,

                 Example 15 : NSA Supportability - NAS Capability

For NSA, there should be two major feature should be supported. One is lower layer band combination and the other one is higher layer dual connectivity. Higher layer dual connectivity (i.e, dual connectivity with NR) is notified by a NAS message with a parameter calledDCNR. This feature is configured in UE network capability in Attach Request (in case of LTE) or Registration Request (in case of NR).

NOTE : This is for NSA Supportability with NAS point of view. For the lower layer capability of NSA Supportability, Refer to Example 16.

 

UE network capability:

  0xf0 (EEA0=1, 128-EEA1=1, 128-EEA2=1, 128-EEA3=1, EEA4=0, EEA5=0, EEA6=0, EEA7=0)

How to handle the ever increasing size of UE capability Information ? - RRC Segmentation

As far as I recall, I have seen many issues even from LTE only cases in later 3GPP release in terms of processing UE capability information in both UE and network (or network simulator) side.

Sometimes UE fails to generate the well structured UE capability information with huge set of features, especially when the number of carrier aggregation gets increased. And problems heppens in network side in similar situation failing to decode properly the lengthy and complicated UE capability Information message.

This issue has become even more serious in NR (both SA and NSA). NR UE capability features in NR is much more complicated than LTE. When the number of aggregated carrier gets increases, the size of the UE capability Information message exceeds the maximum size of RRC signaling message.

To workaround this situation, a new mechanism of RRC signaling is introduced. The new mechanism is called 'Segmented RRC Message'. For further details of this mechanism, I would like to share what Anupam Shrivastava kindly contributed as below.

With the introduction of new UE-capa every release the size of RRC is increasing( below study on UE-capa IE introduction with different 3gpp releases from Rel-15.1 till Rel-17) and in scenarios of CA, HO there are situations when the RRC size will exceed the limit for 9k bytes as explained above for the NR, to overcome this situation we need to fragment/segment the capa into smaller chunks for which Segmentation is introduced, though it comes with a cost of additional delay in UECapabilityinformation received by gNB , as gNB need extra time to receive all segments and then reassemble them.

The maximum supported size of a PDCP SDU is 9000 bytes. The maximum supported size of a PDCP Control PDU is 9000 bytes. So the UE capability Information with size greater than 9000 byte should be split into multiple rrc messages and then combined later.

The RRC message carrying each of the segment is as follows :

ULDedicatedMessageSegment-r16 ::= SEQUENCE {

   criticalExtensions CHOICE {

      ulDedicatedMessageSegment-r16                 ULDedicatedMessageSegment-r16-IEs,

      criticalExtensionsFuture                             SEQUENCE {}

   }

}

ULDedicatedMessageSegment-r16-IEs ::= SEQUENCE {

   segmentNumber-r16                                     INTEGER (0..15),

   rrc-MessageSegmentContainer-r16                  OCTET STRING,

   rrc-MessageSegmentType-r16                        ENUMERATED {notLastSegment, lastSegment},

   lateNonCriticalExtension                                 OCTET STRING OPTIONAL,

   nonCriticalExtension                                      SEQUENCE {} OPTIONAL

}
