Abstract
Certain aspects of the present disclosure provide methods and apparatus for joint support of coordinated multipoint (CoMP) operations and carrier aggregation (CA). One method generally includes receiving signaling indicating a configuration, from a set of possible configurations, that defines how the UE is to communicate with one or more base stations (BSs) using coordinated multipoint (CoMP) operations on one or more component carriers (CCs) and communicating in accordance with the configuration.
Claims16
A method for wireless communication by a user equipment (UE) comprising:
- signaling one or more UE capability configurations selected from a first set of possible configurations indicating capabilities supported by the UE for communication with one or more base stations (BSs) using coordinated multipoint (CoMP) operations;
- receiving signaling, based at least in part on the one or more signaled UE capability configurations, indicating a configuration selected from a second set of possible configurations that defines how the UE is to communicate with the one or more BSs using CoMP operations on multiple component carriers (CCs) in a carrier aggregated (CA) configuration, wherein each of the configurations of the first set of possible configurations indicates a maximum number of channel state information (CSI) processes supported by the UE on the CCs, and wherein the maximum number of CSI processes supported by the UE on the CCs depends at least on the aggregate bandwidth of the CCs that support CoMP operations;
- and
- communicating in accordance with the configuration indicated by the received signaling.
