Mask for reference signal measurements
Aspects of the present disclosure provide a method, a computer-readable medium, and an apparatus for wireless communication, for example for reference signal measurements. An example method, performed by a user equipment, generally includes determining a duration for reference signal measurements of a network entity and beamforming one or more radio frequency chains in one or more directions for the reference signal measurements of the network entity during the duration.
1. A method of wireless communication of a user equipment (UE), comprising:
determining a duration for reference signal measurements of a network entity; and
beamforming a first subset of radio frequency chains of a set of radio frequency chains in one or more directions for the reference signal measurements of the network entity during the duration;
performing the reference signal measurements of the network entity using the beamformed first subset of radio frequency chains; and
communicating data with a serving entity using a second subset of radio frequency chains of the set of radio frequency chains during the duration.
2. The method of claim 1 , wherein the duration is determined based on a configuration message received from the serving network entity.
3. The method of claim 1 , wherein the duration is determined based on a reference signal transmission pattern from the network entity.
4. The method of claim 3 , wherein the reference signal transmission pattern is determined by measuring new radio synchronization signal (NR-SS) from the network entity.
5. The method of claim 1 , further comprising receiving, from the serving network entity, a number of radio frequency chains to beamform and the one or more directions to perform the reference signal measurements.
6. The method of claim 5 , wherein the number of radio frequency chains to beamform is determined based on at least one of physical broadcast channel (PBCH), L1/L2, or radio resource control (RRC) configuration information received from the other network entity.
7. The method of claim 1 , further comprising receiving, from the serving network entity, a direction not to perform the reference signal measurements during the duration.
8. The method of claim 1 , wherein the duration is determined based on one or more of a system frame number (SFN), a subframe index (SFI), a slot, or a mini-slot.
9. The method of claim 1 , further comprising receiving a signal from the serving network entity to terminate the reference signal measurements early before the duration expires.
10. An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
means for determining a duration for reference signal measurements of a network entity; and
means for beamforming a first subset of radio frequency chains of a set of radio frequency chains in one or more directions for the reference signal measurements of the network entity during the duration;

14. The apparatus of claim 10 , further comprising receiving, from the serving network entity, a number of radio frequency chains to beamform and the one or more directions to perform the reference signal measurements.
15. A non-transitory computer-readable medium storing computer executable code, comprising code to:
determine a duration for reference signal measurements of a network entity; and
beamform a first subset of radio frequency chains of a set of radio frequency chains in one or more directions for the reference signal measurements of a different network entity during the duration;
perform the reference signal measurements of the different network entity using the beamformed first subset of radio frequency chains; and
communicate data with the network entity using a second subset of radio frequency chains of the set of radio frequency chains during the duration.
16. The non-transitory computer-readable medium of claim 15 , wherein the duration is determined based on a configuration message received from the serving network entity.
17. The non-transitory computer-readable medium of claim 15 , wherein the duration is determined based on a reference signal transmission pattern from the network entity.
18. The non-transitory computer-readable medium of claim 17 , wherein the reference signal transmission pattern is determined by measuring new radio synchronization signal (NR-SS) from the network entity.
19. The non-transitory computer-readable medium of claim 15 , further comprising receiving, from serving network entity, a number of radio frequency chains to beamform and the one or more directions to perform the reference signal measurements.
20. An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
a memory; and
at least one processor coupled with the memory and configured to:
determine a duration for reference signal measurements of a network entity; and
