Abstract
Embodiments of a system and method for reporting uplink control information (UCI) are generally described herein. In some embodiments, a first and second component carrier (CC) is provided for a user equipment (UE). The first and second CC are configured with transmission mode (TM) 10 and TMs 1-9, respectively. A first channel state information (CSI) report for the first CC with TM 10 and a second CSI report for the second CC with at least one of TMs 1-9 are scheduled for transmission in a subframe. A collision is detected between the first and second CSI reports. Priority is assigned to the first CSI report or the second CSI report based on a prioritization parameter. The prioritized CSI report is transmitted based the prioritization parameter.

2. An apparatus of user equipment (UE), the apparatus comprising processing circuitry and transceiver circuitry configured to:
-
receive radio-resource control (RRC) signaling from an enhanced node B (eNB) to configure the UE in transmission mode 10 for periodic channel state information (CSI) reporting for each of two or more active serving cells, using a physical uplink control channel (PUCCH), the CSI reporting being in accordance with a PUCCH reporting type, of a plurality of PUCCH reporting types, for each of two or more active serving cells; generate CSI reports for each of the two or more active serving cells, each CSI report configured in accordance with one of the PUCCH reporting types; and drop one or more of the CSI reports generated for different serving cells, for PUCCH reporting types having a same priority, when a collision occurs, wherein the one or more of the CSI reports are dropped based on one or more of a serving cell index or CSI process identifier (ID) associated with the CSI reports. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

21. An apparatus of user equipment (UE), the apparatus comprising processing circuitry and transceiver circuitry configured to:
-
receive radio-resource control (RRC) signaling from an enhanced node B (eNB) to configure the UE for periodic channel state information (CSI) reporting for two or more active serving cells in which the UE configured for transmission mode 10 for at least one of the active serving cells and configured for one of transmission modes 1-9 for at least one other of the active serving cells, the RRC signaling configured to UE for periodic CSI reporting using a physical uplink control channel (PUCCH), the CSI reporting being in accordance with a PUCCH reporting type, of a plurality of PUCCH reporting types, for each of two or more active serving cells; generate CSI reports for each of the two or more active serving cells, each CSI report configured in accordance with one of the PUCCH reporting types; and drop one or more of the CSI reports generated for different serving cells, for a given subframe and for PUCCH reporting types having a same priority, when a collision occurs. - View Dependent Claims (22, 23)
