Aperiodic channel state information (CSI) reporting for carrier aggregation
First Claim
1. A non-transitory machine readable medium comprising instructions that, when executed, cause a user equipment (UE) to:
- receive a data payload transmitted via more than five serving cells according to a carrier aggregation (CA) mode and at most thirty-two serving cells;
receive a first value associated with a channel state information (CSI) request field, wherein the first value is associated with a first subset of the more than five serving cells;
calculate at least one CSI parameter for each serving cell of the first subset;
generate an aperiodic CSI report based at least in part on the at least one CSI parameter for each serving cell of the first subset; and
transmit the aperiodic CSI report via a physical uplink shared channel (PUSCH).

Abstract
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).
