Many values for the MCS index have been defined in the specification. Value ranges from 0 to 31.
Each MCS index values corresponds to different combination of "number of spatial streams + modulation type + Coding rate" .
In case of PDSCH resource allocation, eNodeB considers feedback from the UE but in case of PMCH where data is transmitted only at downlink. How a particular MCS index would be chosen for multimedia multicast broadcast data transmission ?
If I am correct, selection of MCS index is done at MCE and sends to eNodeBs/cells belong to the same MBSFN area ?
In this case when MCS index is selected by MCE, how MCE take decision on this factor ?
I am also looking for set of MCS index values which can be used for MBMS transmission ?
