Patent ID: 11387884

Abstract:
A method for operating a UE for CSI reporting comprises receiving configuration information for a CSI report, where the configuration information configures a PMI codebook and partitions the PMI codebook into first and second PMI subsets respectively indicating first and second subsets of a set of components S to represent N3 precoding matrices; determining, based on the configuration information, the CSI report comprising first and second CSI parts, the second CSI part including the second PMI subset and partitioned into N groups; selecting M groups from the N groups of the second CSI part based on a resource allocation for transmission of UCI, where M ∈ {1, . . . , N}; and transmitting, over an UL channel, the UCI including a first UCI part and a second UCI part, the first UCI part including the first CSI part and the second UCI part including the M groups from the N groups of the second CSI part.
