Abstract:
Techniques and examples of layer mapping, channel state information (CSI) feedback and hybrid automatic repeat request (HARQ) feedback in mobile communications are described. A user equipment (UE) receives from a base station one or more reference signals, which may be non-zero power (NZP) or zero power (ZP), on one or more time-frequency resources indicated by a network via a communication link between the UE and the base station. The UE estimates, based on the receiving, a subspace spanned by a channel response of an interfering signal. The UE determines a precoding matrix indicator (PMI) based on the estimated subspace. The UE transmits to the base station a channel state information (CSI) feedback comprising at least the PMI. The PMI may include at least a first precoder and a second precoder.

Claim (Index 18):
The method of  claim 17 , wherein the CSI feedback further comprises information related to a signal quality of each spatial layer of a plurality of spatial layers with respect to the communication link, and wherein the information related to the signal quality of each spatial layer of the plurality of spatial layers with respect to the communication link comprises one or more of:\n information indicating layer indexes in a sorted order based on signal quality of the plurality of spatial layers; quantized values for a signal-to-noise ratio (SNR), a channel quality indicator (CQI) or a supported spectral efficiency (SE) of each spatial layer or each spatial layer group of the plurality of spatial layers; and quantized values for a differential of each of a SNR, a CQI or a SE of each spatial layer or each spatial layer group of the plurality of spatial layers relative to a CQI reported for each codeword.
