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 37):
The apparatus of  claim 36 , wherein the configuration of the at least one processor to identify the default reference rank includes configuration of the at least one processor:\n to determine a number of antenna ports associated with the CSI-RS resource identified by a last reported beam selection indicator; to identify a lowest possible rank indicator associated with the number of antenna ports, wherein the default reference rank is the lowest possible rank indicator.
