Channel state information feedback scheme for cooperative multi point transmission and carrier aggregation scenario
First Claim
1. 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 each of two or more active serving cells, using a physical uplink control channel (PUCCH), the periodic CSI reporting being in accordance with a PUCCH reporting type, of a plurality of PUCCH reporting types, for each of the 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 active serving cells, for PUCCH reporting types having a same priority, when a collision between the CSI reports occurs,wherein the one or more of the CSI reports are dropped based on one or more of a transmission mode, a serving cell index or CSI process identifier (ID) associated with the CSI reports,wherein the UE is configured for transmission mode 10 in at least one of the active serving cells,wherein the one or more of the serving cell index or CSI process ID associated with the CSI reports used to determine the one or more of the CSI reports dropped is dependent on in which transmission mode the UE is configured in at least one other of the active serving cells, andwherein when the UE is configured for transmission mode 1-9 in the at least one other of the active serving cells, the UE is further to receive an update of a virtual CSI process index from the eNB through the RRC signaling, the update configured to change prioritization between the transmission modes 1-9 and transmission mode 10 by adjustment of the virtual CSI process index of the transmission modes 1-9 between 0 and a non-zero value.

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.
