APERIODIC CHANNEL STATE INFORMATION (CSI) REPORTING FOR CARRIER AGGREGATION

摘要

Aperiodic channel state information (CSI) reporting is discussed. An example user equipment includes a receiver circuit, processor, and transmitter circuit. The receiver circuit receives transmissions from a plurality of serving cells via a carrier aggregation (CA) mode and receives an aperiodic CSI reporting request indicating a set for CSI reporting. The plurality of serving cells comprises at least six serving cells, and one or more of the plurality is associated with the indicated set. The processor is operably coupled to the receiver circuit and calculates one or more CSI parameters for each serving cell of the plurality that is associated with the indicated set; and generates an aperiodic CSI report based at least in part on the calculated CSI parameters for each serving cell associated with the indicated set. The transmitter circuit transmits the aperiodic CSI report to an Evolved NodeB (eNB) via a physical uplink shared channel (PUSCH).

主权项

1. A user equipment (UE), comprising:
a receiver circuit configured to receive transmissions via a plurality of serving cells according to a carrier aggregation (CA) mode and to receive an aperiodic channel state information (CSI) reporting request that indicates a set for CSI reporting, wherein the plurality of serving cells comprises at least six serving cells, and wherein one or more of the plurality of serving cells is associated with the indicated set; a processor operably coupled to the receiver circuit and configured to:
calculate one or more CSI parameters for each serving cell of the plurality of serving cells that is associated with the indicated set; andgenerate an aperiodic CSI report based at least in part on the calculated CSI parameters for each serving cell associated with the indicated set; and a transmitter circuit configured to transmit the aperiodic CSI report to an Evolved NodeB (eNB) via a physical uplink shared channel (PUSCH).
