Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. The UE may receive, from the base station, a reference signal carried on one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

First claim

What is claimed is:

1. A method of wireless communication performed by a user equipment (UE), comprising:
transmitting, to a network entity, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE,
wherein the information indicating the L1-SINR measurement capability indicates:
a first configuration for a reference signal, and
a second configuration for the reference signal, and

wherein the first configuration includes a configuration for a channel measurement resource (CMR) without a dedicated interference measurement resource (IMR); and

measuring the reference signal based at least in part on the L1-SINR measurement capability.

2. The method of claim 1 , wherein the information indicating the L1-SINR measurement capability further indicates:
a third configuration for the reference signal.

3. The method of claim 2 ,
wherein the second configuration is a configuration in which the one or more resources include a CMR and a dedicated zero power IMR (ZP IMR), and
wherein the third configuration is one of:
a configuration in which the one or more resources for the reference signal include a CMR with a dedicated non-zero power IMR (NZP IMR), or
a configuration in which the one or more resources for the reference signal include a CMR with a dedicated ZP IMR and a dedicated NZP IMR.

4. The method of claim 2 , wherein the information indicating the L1-SINR measurement capability further indicates:
a fourth configuration for the reference signal.

5. The method of claim 1 , wherein the second configuration includes a configuration in for a CMR with a dedicated IMR in which the network entity does not transmit a signal.

6. The method of claim 1 , wherein the second configuration includes a configuration for a CMR with a dedicated non-zero power interference measurement resource (NZP IMR).

7. The method of claim 1 , wherein the second configuration includes a configuration for a CMR with a dedicated IMR and a dedicated non-zero power interference measurement resource (NZP IMR).

8. The method of claim 1 , further comprising:
obtaining an L1-SINR measurement based at least in part on the reference signal; and
transmitting, to the network entity, a report including the L1-SINR measurement.

9. The method of claim 1 , wherein the reference signal is a channel state information reference signal (CSI-RS).

10. A method of wireless communication performed by a network entity, comprising:
receiving, from a user equipment (UE), information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE,
wherein the information indicating the L1-SINR measurement capability indicates:
a first configuration for a reference signal, and
a second configuration for the reference signal, and

wherein the first configuration includes a configuration for a channel measurement resource (CMR) without a dedicated interference measurement resource (IMR); and

transmitting, to the UE, a reference signal based at least in part on the L1-SINR measurement capability.

11. The method of claim 10 , wherein the information indicating the L1-SINR measurement capability further indicates:
a third configuration for the reference signal.

12. The method of claim 11 ,
wherein the second configuration is a configuration in which the one or more resources for the reference signal include a CMR and a dedicated zero power IMR (ZP IMR), and
wherein the third configuration is one of:
a configuration in which the one or more resources for the reference signal include a CMR with a dedicated non-zero power IMR (NZP IMR), or
a configuration in which the one or more resources for the reference signal include a CMR with a dedicated ZP IMR and a dedicated NZP IMR.

13. The method of claim 11 , wherein the information indicating the L1-SINR measurement capability further indicates:
a fourth configuration for the reference signal.

14. The method of claim 10 , wherein the second configuration includes a configuration for a CMR with a dedicated IMR in which the network entity does not transmit a signal.

15. The method of claim 10 , wherein the second configuration includes a configuration for a CMR with a dedicated non-zero power interference measurement resource (NZP IMR).

16. The method of claim 10 , wherein the second configuration includes a configuration for a CMR with a dedicated IMR and a dedicated non-zero power interference measurement resource (NZP IMR).

17. The method of claim 10 , further comprising:
receiving, from the UE, a report including an L1-SINR measurement obtained by the UE based at least in part on the reference signal.

18. The method of claim 10 , wherein the reference signal is a channel state information reference signal (CSI-RS).

19. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
transmit, to a network entity, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE,
wherein the information indicating the L1-SINR measurement capability indicates:
a first configuration for a reference signal, and
a second configuration for the reference signal, and

wherein the first configuration includes a configuration for a channel measurement resource (CMR) without a dedicated interference measurement resource (IMR); and
