Tracking reference signal availability indication

1. A user equipment (UE) for wireless communication, comprising:

a memory; and

one or more processors, coupled to the memory, configured to:

receive configurations of a set of tracking reference signal (TRS) resource sets;

receive an availability indication associated with one or more groups of TRS resource sets from the set of TRS resource sets, wherein:

the availability indication includes an indication for each group of the one or more groups of TRS resource sets, and

an indication, for a group, indicates whether all TRS resource sets included in the group are to be transmitted; and

communicate with a network entity based at least in part on receiving the availability indication.

2. The UE of claim 1 , wherein the availability indication is received via Layer 1 signaling.

3. The UE of claim 1 , wherein the availability indication is associated with a paging signal.

4. The UE of claim 1 , wherein the configuration indicates, for a TRS resource set, an identifier of a group associated with the TRS resource set.

5. The UE of claim 1 , wherein the one or more processors are further configured to:

receive an indication of the one or more groups of TRS resource sets.

6. The UE of claim 5 , wherein the indication of the one or more groups of TRS resource sets is included in the configuration of the set of TRS resource sets.

7. The UE of claim 1 , wherein a quantity of TRS resource sets to be included in each group, of the one or more groups of TRS resource sets, is defined, and

wherein a group, of the one or more groups of TRS resource sets, is formed based at least in part on the quantity and based at least in part on identifiers of the set of TRS resource sets.

8. The UE of claim 7 , wherein a first group includes a first subset of TRS resource sets, from the set of TRS resource sets, and a second group includes a second subset of TRS resource sets from the set of TRS resource sets,

wherein the first group and the second group both include the quantity of the TRS resource sets, and

wherein TRS resource sets included in the first group and the second group are based at least in part on an order of the identifiers of the set of TRS resource sets.

9. The UE of claim 1 , wherein the availability indication is associated with multiple signals, and wherein each signal, of the multiple signals, indicates an availability associated with a group of the one or more groups of TRS resource sets.

10. A network entity for wireless communication, comprising:

a memory; and

one or more processors, coupled to the memory, configured to:

transmit configurations of a set of tracking reference signal (TRS) resource sets intended for one or more user equipment (UEs); and

transmit an availability indication associated with one or more groups of TRS resource sets from the set of TRS resource sets, wherein:

the availability indication includes an indication for each group of the one or more groups of TRS resource sets, and

an indication, for a group, indicates whether all TRS resource sets included in the group are to be transmitted.

11. The network entity of claim 10 , wherein the configuration indicates, for a TRS resource set, an identifier of a group associated with the TRS resource set.

12. A method of wireless communication performed by a user equipment (UE), comprising:

receiving configurations of a set of tracking reference signal (TRS) resource sets;

receiving an availability indication associated with one or more groups of TRS resource sets from the set of TRS resource sets, wherein:

the availability indication includes an indication for each group of the one or more groups of TRS resource sets, and

an indication, for a group, indicates whether all TRS resource sets included in the group are to be transmitted; and

communicating with a network entity based at least in part on receiving the availability indication.

13. The method of claim 12 , wherein the availability indication is received via Layer 1 signaling.

14. The method of claim 12 , wherein the availability indication is associated with a paging signal.

15. The method of claim 12 , wherein the configuration indicates, for a TRS resource set, an identifier of a group associated with the TRS resource set.

16. The method of claim 12 , further comprising:

receiving an indication of the one or more groups of TRS resource sets.

17. The method of claim 16 , wherein the indication of the one or more groups of TRS resource sets is included in the configuration of the set of TRS resource sets.

18. The method of claim 12 , wherein a quantity of TRS resource sets to be included in each group, of the one or more groups of TRS resource sets, is defined, and

wherein a group, of the one or more groups of TRS resource sets, is formed based at least in part on the quantity and based at least in part on identifiers of the set of TRS resource sets.

19. The method of claim 18 , wherein a first group includes a first subset of TRS resource sets, from the set of TRS resource sets, and a second group includes a second subset of TRS resource sets from the set of TRS resource sets,

wherein the first group and the second group both include the quantity of the TRS resource sets, and

wherein TRS resource sets included in the first group and the second group are based at least in part on an order of the identifiers of the set of TRS resource sets.

20. The method of claim 12 , wherein the availability indication is associated with multiple signals, and wherein each signal, of the multiple signals, indicates an availability associated with a group of the one or more groups of TRS resource sets.
