Abstract:
Design of precoding and feedback for user equipment (UE)-specific reference signals (UE-RS)-based open-loop and semi-open-loop multiple input, multiple output (MIMO) systems is discussed. Aspects of the present disclosure provide for sub-resource block (RB) random precoding that allows for greater diversity gain in a lower bandwidth. In addition, the recoding may be performed using resource element (RE)-level layer shifting that provides for a number of precoders to be assigned to a number of layers for every such continuous subcarrier. As such, two codewords may experience the same effective channel quality with channel quality indicators (CQI) being averaged across all of the layers.

Claim (Index 16):
An apparatus configured for wireless communication, comprising:\n means for randomly selecting a first precoder associated with a first transmission block, wherein the first transmission block includes one of: a first resource block, a first set of bundled resource blocks, or a first sub-resource block selected as a group of contiguous resource elements within a resource block; means for transmitting user equipment (UE)-specific reference signals (UE-RS) and data within the first transmission block, wherein the UE-RS and data are precoded using the first precoder; means for selecting a next precoder associated with a next transmission block, wherein the next transmission block includes one of: a next resource block, a next set of bundled resource blocks, or a next sub-resource block selected as a next group of contiguous resource elements within the resource block; and means for transmitting the UE-RS and data in the next transmission block, wherein the UE-RS and data are precoded with a next precoder.
