Closed Loop MIMO

 

As you may know, 'Closed Loop' is a concept in Control System Theory. Simply put, it is a Feedback System (I would not explain on what is Feedback System here). In LTE Closed Loop MIMO, Network dynamically changes MIMO precoding matrix based on the CSI report (PMI / RI) from UE.  There are many procedures are trigerred or tuned on Network side based on UE report or request as illustrated below. 'Closed Loop MIMO' is the highlighed portion of this illustration (more accurately (6) represents the essence of 'Closed Loop MIMO'). If you want to see the overall description of the whole picture, see  UE Feedback / Measurement and Scheduling page)

 

 

 

Of course it is impossible to explain in detail with a couple of arrow shown above. Surprisingly complicated procedures are hidden in each of the arrows in above sequence. Followings are the details to be covered in this page.

 

 

Sequence of Closed Loop MIMO

 

Overall sequence for Closed Loop MIMO goes as follows. It may look simple.. a lot of things are going at the bottom (at lower layer) of both UE and Network side.  Just understanding the full detail would take pretty much of efforts.

 

Step

Direction

Message

Description

1

UE <-- NW

RRC Connection Reconfiguration Configure TM4 / CQI / PMI / RI

2

UE --> NW

RRC Connection Reconfiguration Complete  

3

UE --> NW

Periodic CQI Report This happens periodically

4

UE <-- NW

DCI 0 with CSI Request

 

5

UE --> NW

Aperiodic PMI/RI Report This happens only when Step 4 is done

6

UE <-- NW

DCI 2 with adjusted PMI value This adjustment happens when Step 5 is done

 

 

RRC Connection Reconfiguration

 

In terms of RRC Connection Reconfiguration setting, just to give you a couple of examples would be enough. However, interpreting the meaning of these IEs related to Closed Loop MIMO is not a simple matter.

 

See following pages for the detailed explanation of each IE (Information Elements) on Periodic / Aperiodic report. It would take pretty much time and effort to real through all of these and take even more time/effort to fully understand it. Even if you figured out everything at first reading, you would get confused again later .. However, just by quick look back everything would get clear again if you had spent enough time and effort at the first reading and fully understood it.

 

 

Examples of RRC Connection Reconfiguration >================================

 

Followings are some of the configurations for TM4 Closed Loop MIMO that I confirmed working.

How does Network assign Precoding Information ?

 

In case of 2x2 Closed Loop MIMO, eNB would specify the Precoding Information field in DCI 2 based on following table.

 

< 36.212 Table 5.3.3.1.5-4: Content of precoding information field for 2 antenna ports >

 

 

In case of 4x4 Closed Loop MIMO, eNB would specify the Precoding Information field in DCI 2 based on following table.

 

< 36.211 Table 5.3.3.1.5-5: Content of precoding information field for 4 antenna ports >
