I am scratching my head here, trying to figure out if there is something wrong with the new LTE System Toolbox.
The function in question is ltePMIInfo.m
The lines in question are:
140 if (strcmpi(chs.TxScheme,'SpatialMux') || enb.CSIRefP~=8)
141 if (chs.NLayers==2 && enb.CellRefP==2)
142 info.MaxPMI=1; % !!! Seems to be wrong!!
To my understanding, in case of Spatial Multiplexing with 2 layers and 2 transmit antenna ports, there are a maximum of 3 precoders in the codebook (refer to 3GPP 36.211, Table 6.3.4.2.3-1). So setting maximum PMI to 1 means you are limiting yourself to just codebook indices 0 and 1. What happened to 2? Am I missing something?
