User terminal and radio communication method
A user terminal includes a control section that measures a plurality of Signal to Interference plus Noise Ratios (SINRs), based on one or more signal measurement resources and a plurality of interference measurement resources, and a transmitting section that reports one or more SINRs among the plurality of the SINRs and one or more indices associated with the resources used for the one or more SINRs. According to one aspect of the present disclosure, appropriate beam reporting can be performed.
1. A terminal comprising:
a processor that measures a plurality of indicators based on a plurality of channel measurement resources and a plurality of interference measurement resources, the indicators being different from reference signal received power; and
a transmitter that reports one or more indicators among the plurality of indicators and one or more indices that are associated with resources used for measurement of the one or more indicators,
wherein the one or more indices each correspond to a combination of one of the channel measurement resources and one of the interference measurement resources, and
wherein the transmitter reports capability information indicating a maximum number of the plurality of channel measurement resources and capability information indicating a maximum number of the plurality of interference measurement resources.
2. The terminal according to claim 1 , wherein the transmitter does not report an interference measurement resource index.
3. The terminal according to claim 1 , wherein
the channel measurement resources are at least either synchronization signal/physical broadcast channel (SS/PBCH) block resources or non-zero power channel state information reference signal (NZP CSI-RS) resources, and
the interference measurement resources are NZP CSI-RS resources or CSI-Interference Management (IM) resources.
4. The terminal according to claim 1 , wherein the indicators are Signal to Interference plus Noise Ratio (SINR).
