Claim Text:
1. User Equipment (UE) comprising hardware processing circuitry configured to: receive, from an Evolved Node-B (eNB), an aperiodic channel quality indicator (CQI) type parameter that indicates either a first or a second aperiodic CQI type for use in a determination of an aperiodic CQI; determine the aperiodic CQI based on the aperiodic CQI type parameter; and transmit an aperiodic CQI measurement report based on the aperiodic CQI, wherein for the first aperiodic CQI type, the aperiodic CQI is based on a signal quality for one or more channel-state information reference signals (CSI-RS) received at the UE, wherein for the second aperiodic CQI type, the aperiodic CQI is based on a signal quality for a physical downlink shared channel (PDSCH) block received at the UE, and wherein the aperiodic CQI type parameter indicates the first aperiodic CQI type when the determination of the aperiodic CQI is for a time period in which the UE is scheduled to receive a single-user multiple-input multiple-output (SU-MIMO) signal from the eNB, and the aperiodic CQI type parameter indicates the second aperiodic CQI type when the determination of the aperiodic CQI is for a time period in which the UE is scheduled to receive a MU-MIMO signal from the eNB.
