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 3):
The method of  claim 1 , wherein the first precoder is approximately parallel to the channel response of the interfering signal, and wherein the second precoder is approximately orthogonal to the channel response of the interfering signal.
