Method for group based l1-sinr measurement and report

A network device including at least a first Transmission and Reception Point (TRP) and a second TRP, the network device comprising:

• at least one antenna;
• at least one radio coupled to the at least one antenna;
• and
• a processor coupled to the at least one radio;
• wherein the network device is configured to:
• generate a message used for a wireless device to perform Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) measurement,
• wherein the L1-SINR measurement is related to inter-beam interference for beams associated with the first TRP and the second TRP;
• and
• wherein the message at least includes:
• a first channel measurement resource (CMR) set including multiple first CMRs for the first TRP, and a first interference measurement resource (IMR) set including multiple first IMRs for the first TRP, which is corresponding to the first CMR set;
• a second CMR set including multiple second CMRs for the second TRP, and a second IMR set including multiple second IMRs for the second TRP, which is corresponding to the second CMR set;
• and
• relation information, indicating a first relation between the first CMR set and the second IMR set, and a second relation between the second CMR set and the first IMR set;
• and
• send the message to the wireless device.

A wireless device, comprising:

• at least one antenna;
• at least one radio coupled to the at least one antenna;
• and
• one or more processor coupled to the at least one radio;
• wherein the one or more processors are configured to cause the wireless device to:
• receive, from a network device including at least a first Transmission and Reception Point (TRP) and a second TRP, a message used for the wireless device to perform Layer 1 Signal to Interference plus Noise Ratio (L1-SINR) measurement,
• wherein the message at least includes:
• a first channel measurement resource (CMR) set including multiple first CMRs for the first TRP, and a first interference measurement resource (IMR) set including multiple first IMRs for the first TRP, which is corresponding to the first CMR set;
• a second CMR set including multiple second CMRs for the second TRP, and a second IMR set including multiple second IMRs for the second TRP, which is corresponding to the second CMR set;
• and
• relation information, indicating a first relation between the first CMR set and the second IMR set, and a second relation between the second CMR set and the first IMR set;
• and
• perform the L1-SINR measurement with respect to multiple CMR pairs at least based on the received message, wherein the L1-SINR measurement is related to inter-beam interference for beams associated with the first TRP and the second TRP.
