CHANNEL STATE INFORMATION FOR ENHANCED CARRIER AGGREGATION

摘要

Methods, systems, and devices are described for wireless communication in a system that supports enhanced carrier aggregation (eCA). An eCA configuration with a large number of component carriers (CCs) may include CCs grouped into channel state information (CSI) reporting groups. Channel state reports for the CCs in each group may be reported together. In some cases, individual CC reports may be multiplexed into a single report, and in other cases a single channel state report may contain information related to each CC in the group. The combined reports may be transmitted over an uplink control channel or an uplink data channel, or both. Collisions between reports may be resolved based on the reporting type of the groups or the serving cell indices of the CCs in the group.

主权项

1. A method of wireless communication by a user equipment (UE), comprising:
identifying a channel state information (CSI) reporting configuration for each of a plurality of CSI reporting groups, wherein each CSI reporting group comprises a plurality of component carriers from a set of component carriers in a carrier aggregation configuration of the UE; generating a combined report for each of the plurality of CSI reporting groups based at least in part on the corresponding CSI reporting configuration; and transmitting one or more of the combined reports.
