Abstract
Where receiver performance at a User Equipment (UE) is similar using a coarse precoder codebook as using a fine resolution precoder codebook, the signaling of a two-component precoder codebook is modified such that a precoder codeword is signaled to the UE in only a portion of the physical resources allocated for precoder codeword signaling to the UE. The remaining portion of the allocated physical resources is used to signal control information to improve the UE's performance.
