Methods selecting modulation/coding schemes mapped to multiple MIMO layers and related user equipment

S Nammi, B Göransson, E Larsson, J Hultell - US Patent 9,031,018, 2015 - Google Patents
A method of operating a user equipment communicating with a base station of a radio
access network may include selecting a multiple-input-multiple-output, MIMO, rank and a
MIMO precoding entity from a codebook of MIMO precoding entities for a downlink
communication from the base station to the user equipment. A modulation/coding scheme to
be mapped to first and second MIMO layers of the downlink communication may be selected
using the MIMO precoding entity. Channel quality information may be communicated …
