1. An apparatus of a user equipment (UE) to report periodic channel state information (CSI), the apparatus comprising one or more processors and memory configured to:
generate a plurality of CSI reports for serving cells for transmission in a subframe, wherein each CSI report corresponds to a physical uplink control channel (PUCCH) reporting type among a plurality of CSI processes having a CSI process index (CSIProcessIndex) and a serving cell index (ServCellIndex) among a plurality of ServCellIndexes; determine different priorities corresponding to each of the plurality of PUCCH reporting types; determine a first collision between CSI reports, among the plurality of CSI reports, having PUCCH reporting types with equal priorities in the subframe and, upon determining the first collision, drop CSI reports corresponding to all CSI processes except a CSI process having the lowest CSIProcessIndex; determine a second collision between CSI reports, after determining the first collision, among retained ones of the plurality of CSI reports, having CSIProcessIndexes with equal priorities in the subframe and, upon determining the second collision, drop the CSI reports corresponding to all ServCellIndexes except a CSI report with the lowest ServCellIndex; and multiplex at least one non-colliding CSI report from among CSI reports that are not dropped and hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback bits for transmission to an eNodeB. |
