Abstract
Designs of precoding and feedback for open-loop and semi-open-loop multiple-input multiple-output (MIMO) systems based on User Equipment (UE) specific reference signals (UE-RS) are discussed. Aspects of the present disclosure provide sub-Resource Block (RB) random precoding that allows for greater diversity gain in lower bandwidth. In addition, RE-encoding may be performed using Resource Element (RE) level layer shifts that provide a number of precoders to be assigned to a number of layers for each such contiguous subcarrier. In this way, both codewords may experience the same effective channel quality, with the Channel Quality Indicator (CQI) being averaged over all layers.
