Abstract:
Disclosed are feedback and transmission devices and methods in full-dimension multi-antenna systems using two-dimensional (2D) planar array antennas, wherein a UE estimates channel states each corresponding to a respective one of multiple domain channels by a reference signal received from a base station, and obtains precoding matrix indicators (PMIs) each corresponding to a respective one of the multiple domain channels and rank indicators (RIs) each corresponding to a respective one of the multiple domain channels based on the estimated channel states. The UE may determine a joint rank indicator (JRI) using the obtained PMIs and the RIs and transmit feedback information containing the determined JRI to the base station.

Claim (Index 15):
The UE of  claim 13 , wherein the processor is further configured to determine a non-zero layer index (NLI) that is index information of a zero layer to be transmitted by the base station to remove inter-layer interference based on the determined JRI and the obtained RIs and PMIs and configure the feedback information to contain the determined NLI, the obtained PMIs and RIs, and correlation indicators (CIs), each of the CIs corresponding to a respective one of the multiple domain channels.
