    Default LTE DL MIMO4x4 4x2 2x2 RRC Message diferentiation

    Hi Experts

    is there anyway to check if the logfile result, UE is clamping with the signal from the 4x4/4x2 or 2x2 cell from RRC message ?

    MIMO can be get from Layer 1 information. I can't found it on RRC Message.

    On QXDM log file, MIMO information can be get from LL1 log : 0xB126 LTE LL1 PDSCH Demapper Configuration, below is the sample.

    02:41:47.666 [0xB126] LTE LL1 PDSCH Demapper Configuration
    Version = 23
    Version 23 {
    Serving Cell ID = 337
    Sub-frame Number = 1
    System Frame Number = 54
    PDSCH RNTIl ID = 779
    PDSCH RNTI Type = C-RNTI
    Number of Tx Antennas (M) = 1 antenna
    Number of Rx Antennas (N) = 2 antennas
    Spatial Rank = rank 1

    Hi rimeka

    In the above M x N does this mean 1x2 SIMO

    These antennas given M & N are for EnodeB?
