MIB/SIB
As in legacy LTE, for LTE-M1, MIB/SIB1/SIB2 carries the most fundamental information for cell detaction and initial attach process. In this page, I will describe all the SIBs related to LTE-M1 operation, but it would take long time for me to complete this page... this is at the initial stage now.
Based on 36.331 5.2.1.2 Scheduling, MIB scheduling is described as below :
The MIB uses a fixed schedule with a periodicity of 40 ms and repetitions made within 40 ms. The first transmission of the MIB is scheduled in subframe #0 of radio frames for which the SFN mod 4 = 0, and repetitions are scheduled in subframe #0 of all other radio frames. For TDD/FDD system with a bandwidth larger than 1.4 MHz that supports BL UEs or UEs in CE, MIB transmission may be repeated in subframe#9 of the previous radio frame for FDD and subframe #5 of the same radio frame for TDD.
This implies that in BL/CE FDD case, a new MIB is transmitted over two subframe (subframe #9 and #0) every 40 ms. But MIB is retransmitted at every subframe where SFN mod 4 is not 0. Therefore, if you see the MIB transmission on spectrum analyzer, you would see the MIB transmission over two subframe at every 10 ms as you see in Example : MIB/SIB1/SIB2 on Spectrum Analyzer
Following is the contents of MIB for BL/CE (LTE-M1) :
MasterInformationBlock ::= SEQUENCE { dl-Bandwidth ENUMERATED { n6, n15, n25, n50, n75, n100}, phich-Config PHICH-Config, systemFrameNumber BIT STRING (SIZE (8)), schedulingInfoSIB1-BR-r13 INTEGER (0..31), spare BIT STRING (SIZE (5)) }
schedulingInfoSIB1-BR-r13 : This indicate whether SystemInformationBlockType1-BR is scheduled or not and if it is scheduled, what is the repetition pattern of the SystemInformationBlockType1-BR. If this IE is set to be 0, it means SystemInformationBlockType1-BR is not scheduled. If this IE is a none zero value, it means SystemInformationBlockType1-BR is scheduled and the repetition pattern is defined in the following table.
<36.213-Table 7.1.6-1: Number of repetitions for PDSCH carrying SystemInformationBlockType1-BR for BL/CE UE.>
phich-Config : This IE will be ignored in LTE M1(BL/CE) UE (Refer to 36.331 MasterInformationBlock section for confirm).

SystemInformationBlockType1-BR
The overall function and the information carried by SIB1-BR is similar to SIB1 of legacy LTE. The contents of SIB1-BR can be categorized as below.
One of the major difference between SIB1-BR and legacy LTE SIB1 is about resource allocation (time domaining scheduling and frequency domain location). In case of legacy LTE, the scheduling for SIB1 is determined by relatively simple logic as described in LTE : SIB scheduling. However, in LTE BL/CE, SIB1-BR scheduling is much complicated as described in this section.
The fundamental logics for SIB1-BR scheduling is defined in 36.211-6.4.1 Physical downlink shared channel for BL/CE UEs, but you would need a couple of additional specifications (e.g, 36.213, 36.331) for the full details. Or just read this page :)
< How the SIB1-BR transmission timing is determined ? >
The time domain scheduling for SIB1-BR is determined by only a single IE (information element) in MIB. However, real scheduling is pretty complex. Then how the only one parameter can determined such a complicated scheduling. One of the most common trick for this kind of case is to use various kinds of predefined tables and the IE in RRC message just point to a specific record in the table. In case of SIB1-BR case, the time domain scheduling is defined by two tables : 36.211-Table 6.4.1-1 and Table 6.4.1-2. How can we figure out which of the two tables to use ? It is the system bandwidth. If the system bandwidth is same or lower than 3 Mhz, 36.211-Table 6.4.1-1 will be applied and if the system bandwidth is greater than 3 Mhz, 36.211-Table 6.4.1-2 will be applied. Now let's look inside the table Table 6.4.1-2. You see three records highlighted in different colors. Now the question is how we can figure out which records to use ? (In case of Table 6.4.1-1, there is only one record. so you don't have to worry about this). It is determined by another table : 36.213-Table 7.1.6-1. You can associate the two tables (36.213-Table 7.1.6-1 and 36.211-Table 6.4.1-2) by color coding. Then the last question is how can we figure out which color (4 or 8 or 16) in 36.213-Table 7.1.6-1 ? It is defined by SystemInformationBlockType1-BR in MIB.
< How the Narrowband index for SIB1-BR is determined ? >
Now let's look into how the frequency domain location for SIB1-RB. Unfortunately we have to do a little bit of math to figure this out whether you like it or not :). The frequency domain location (Narrowband Index) is determined by following equation. You don't have to care too much about the equation unless you are not a baseband engineer who has to implement this algorithm. The only thing you need to know is that the frequency domain location (Narrowband Index) changes at every transmission.
Following is from 36.211 - 6.4.1 Physical downlink shared channel for BL/CE UEs.
Following is my Matlab code implementing the above equation. Please let me know if you find any problem with this code. N_ID_cell = 309;
%Sj = [0 3]; % when N_DL_RB = 25 Sj = [0 1 2 5 6 7]; % when N_DL_RB = 50 %Sj = [0 1 2 3 4 7 8 9 10 11]; % when N_DL_RB = 75 %Sj = [0 1 2 3 4 5 6 9 10 11 12 13 14 15]; % when N_DL_RB = 100 N_S_NB = length(Sj); N_DL_RB = 50;
if (N_DL_RB < 12) m = 1; elseif ((N_DL_RB >= 12) & (N_DL_RB <= 50) ) m = 2; else % if(N_DL_RB > 50) m = 4; end;
for i = 0:(m-1) j = mod((mod(N_ID_cell,N_S_NB) + i * floor(N_S_NB/m)),N_S_NB); nNB = Sj(j+1) end;
Result :-------------------------------------------------------------
nNB = 5, 0
< How Transport Block Size (TBS) for SIB1-BR is determined ? >
The Transport Block Size for SIB1-BR is also determined by a predefined table 36.213-Table 7.1.7.2.7-1 as shown below. The index in the table is determined by schedulingInfoSIB1-BR-r13 IE in MIB.
< How to Configure the StartSymbol for SIB1-BR >
How can UE figure out the start position (start OFDM Symbol) of PDSCH carrying SIB1-BR ? Since LTE-M1 does not support (PCFICH), there should be another mechanism for UE to figure out how many OFDM symbols should be reserved for the control signal for legacy LTE. Theoretically LTE-M1 would not need to reserver the first 1 or 2 or 3 or 4 symbols for control signal since LTE-M1 does not use PCFICH, PHIBH, PDCCH. However, it should consider on any possible collision with legacy LTE operation. So it should leave out the first 1 or 2 or 3 or 4 symbols when it is allocating PDSCH. Then you would the question at the beginning : How can UE figure out the start position (start OFDM Symbol) of PDSCH carrying SIB1-BR ?. The answer is 'it is determined by a predefined rule as below'.
In 36.213-7.1.6.4A PDSCH starting position for BL/CE UEs, it stated as follows :
In case of PDSCH for SIB1-BR, l_DataStart is determined as follows

< How the SIB2 transmission timing is determined ? >

RSRP-ThresholdsPrachInfoList : UE determines which prach resources it will use (i.e, which CE level it will notify to network) based on this parameter. 36.331 describes as follows : The criterion for BL UEs and UEs in CE to select PRACH resource set. Up to 3 RSRP threshold values are signalled to determine the CE level for PRACH, see TS 36.213. The first element corresponds to RSRP threshold 1, the second element corresponds to RSRP threshold 2 and so on, see TS 36.321 . The UE shall ignore this field if only one CE level, i.e. CE level 0, is configured in prach-ParametersListCE. The number of RSRP thresholds present in rsrp-ThresholdsPrachInfoList is equal to the number of CE levels configured in prach-ParametersListCE minus one. A UE that supports powerClass-14dBm shall correct the RSRP threshold values before applying them as follows:
RSRP threshold = Signalled RSRP threshold - min{0, (14-min(23, P-Max))} where P-Max is the value of p-Max field in SystemInformationBlockType1-BR.
prach-ParametersListCE : BL CE UE is supposed to use different PRACH resources depending on CE Level. This IE configures which prach resources the UE has to use for a specific CE level. 36.331 describes as follows : Configures PRACH parameters for each CE level. The first entry in the list is the PRACH parameters of CE level 0, the second entry in the list is the PRACH parameters of CE level 1, and so on.
