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 20):
The base station of  claim 17 ,\n wherein the processor is further configured to, when the JRI is set as 0, recognize that a joint rank (JR) obtained by the PMIs is equal to a composite rank (CR) obtained by the product of the RIs, and recognize the JRI as a difference between the JR and the CR when the JRI is not set as 0.
