Abstract
A method and device for beam reporting are provided. The method includes: using, by a terminal device, reference signal resources in a configured first set for channel measurement for a beam and reference signal resources in a configured second set for interference measurement for the beam; wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set; and calculating and reporting, by the terminal device, SINR, based on results of the channel measurement and the interference measurement.

A method for beam reporting, comprising:
- using, by a terminal device, reference signal resources in a configured first set for channel measurement for a beam and reference signal resources in a configured second set for interference measurement for the beam;
- wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set;
- and
- calculating and reporting, by the terminal device, SINR (Signal-to-Interference and Noise Ratio) based on results of the channel measurement and the interference measurement,
- wherein the reference signal resources in the first set are CSI-RS (Channel State Information-Reference Signal) resources and/or SS (Synchronization Signal)/PBCH (Physical Broadcast Channel) resources;
- wherein the reference signal resources in the second set are CSI-RS resources and/or NZP (Non-Zero-Power) CSI-RS and/or CSI-IM (Channel State Information-Interference Measurement) resources;
- wherein when QCL-Type D configuration is configured to the CSI-RS resource or SS/PBCH block in the first set, the terminal device receives associated CSI-RS resource in the second set for interference measurement by taking that the associated CSI-RS resource is quasi co-located to a RS (Reference Signal), which is the RS with QCL-Type D configuration in a TCI (Transmission Configuration Index) state configured to the CSI-RS resource in the first set or the RS with respect to QCL configuration for the SS/PBCH block in the first set.
A terminal device, comprising:
- a processor and a transceiver, wherein
- the processor is used for using reference signal resources in a configured first set for channel measurement for a beam and reference signal resources in a configured second set for interference measurement for the beam;
- wherein the reference signal resources in the first set are associated by ordering with the reference signal resources in the second set;
- and
- calculating and reporting SINR (Signal-to-Interference and Noise Ratio) based on results of the channel measurement and the interference measurement,
- wherein the reference signal resources in the first set are CSI-RS (Channel State Information-Reference Signal) resources and/or SS(Synchronization Signal)/PBCH (Physical Broadcast Channel) resources;
- wherein the reference signal resources in the second set are CSI-RS resources and/or NZP (Non-Zero-Power) CSI-RS and/or CSI-IM (Channel State Information-Interference Measurement) resources;
- and
- wherein when QCL-Type D configuration is configured to the CSI-RS resource or SS/PBCH block in the first set, the terminal device receives associated CSI-RS resource in the second set for interference measurement by taking that the associated CSI-RS resource is quasi co-located to a RS (Reference Signal), which is the RS with QCL-Type D configuration in a TCI (Transmission Configuration Index) state configured to the CSI-RS resource in the first set or the RS with respect to QCL configuration for the SS/PBCH block in the first set.
