Abstract:
Channel state information (CSI) operations are disclosed with regard to elevation beamforming (EB)/full dimension (FD) multiple input, multiple output (ED/FD-MIMO) operations. With CSI processing associated with multiple CSI-reference signal (CSI-RS) resources, ambiguities may arise in determining the CSI reporting type and rank. CSI reporting type may be determined using a last reported beam selection indicator (BI) or, in the absence of a BI, may be determined according to a predefined rule. When rank and BI are reported separately and rank is absent, user equipment may determine a default reference rank for CSI reporting based on either or both of previously reported rank or BI. When rank and BI are jointly reported, encoding schemes with fixed bitwidths determined based on either CSI-RS processes or resources may be used to enhance decoding. CSI-RS antenna ports, processes, or resources may also be used in determining application of CSI processing relaxation.

Claim (Index 23):
An apparatus configured for wireless communication, comprising:\n means for obtaining identification of a plurality of channel state information\u2014reference signals (CSI-RS) resources associated with a CSI process; means for determining whether to combine a beam selection indicator and a rank indicator into a joint report for reporting to the serving base station, wherein the beam selection indicator identifies a CSI-RS resource of the plurality of CSI-RS resources; means for setting a bit width for the joint report, wherein the bit width is fixed; means for encoding the joint report; and means for transmitting the encoded joint report to the serving base station.
