Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may establish a communication connection with a serving cell associated with a first discontinuous reception (DRX) cycle configuration, determine, based at least in part on at least one of a first on duration of a first DRX cycle indicated by the first DRX cycle configuration or a type of traffic of one or more communications received during the first DRX cycle, an autonomous measurement gap associated with a neighboring cell, and perform a measurement of the neighboring cell during the autonomous measurement gap. Numerous other aspects are provided.

First claim

What is claimed is:

1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
determine an amount of time for a timer used for an autonomous measurement gap associated with a neighboring cell,
the autonomous measurement gap being autonomously determined by the UE;

initiate the timer;
determine that the autonomous measurement gap is to occur based at least in part on determining that the amount of time for the timer has expired; and
perform a measurement of the neighboring cell during the autonomous measurement gap.

2. The UE of claim 1 , wherein, to determine the amount of time for the timer, the one or more processors are configured to:
determine the amount of time for the timer based on a point in time during which the UE typically enters an inactive state.

3. The UE of claim 2 , wherein the one or more processors are further configured to:
identify historical data associated with the UE; and
determine, based on the historical data, the point in time during which the UE typically enters the inactive state.

4. The UE of claim 3 , wherein, to determine the point in time during which the UE typically enters the inactive state, the one or more processors are configured to:
determine the point in time during which the UE typically enters the inactive state by utilizing a machine learning model to analyze the historical data.

5. The UE of claim 1 , wherein, to initiate the timer, the one or more processors are configured to:
initiate the timer at an end of a discontinuous reception (DRX) cycle.

6. The UE of claim 1 , wherein, to determine that the autonomous measurement gap is to occur, the one or more processors are configured to:
determine that the amount of time for the timer has expired before the UE has transitioned from an active state of a discontinuous reception (DRX) cycle to an inactive state of the DRX cycle; and
determine, based on determining that the amount of time for the timer has expired before the UE has transitioned from the active state of the DRX cycle to the inactive state of the DRX cycle, that the autonomous measurement gap is to occur while the UE is in the active state of the DRX cycle.

7. The UE of claim 6 , wherein the UE is in the active state of the DRX cycle after the amount of time for the timer has expired.

8. The UE of claim 1 , wherein, to determine that the autonomous measurement gap is to occur, the one or more processors are configured to:
determine that the UE has transitioned from an active state of a discontinuous reception (DRX) cycle to an inactive state of the DRX cycle before the amount of time for the timer has expired; and
determine that the autonomous measurement gap is to occur before the amount of time for the timer has expired.

9. The UE of claim 1 , wherein, to perform the measurement of the neighboring cell, the one or more processors are configured to:
measure, during the autonomous measurement gap, a beam transmitted by a base station associated with the neighboring cell.

10. The UE of claim 9 , wherein, to measure the beam transmitted by the base station, the one or more processors are configured to:
measure, during the autonomous measurement gap and using one or more receive beams of the UE, the beam transmitted by the base station.

11. The UE of claim 9 , wherein the beam is one of:
a synchronization signal block (SSB) beam, or
a channel state information (CSI) reference signals (CSI-RSs) beam.

12. A method of wireless communication performed by a user equipment (UE), comprising:
determining an amount of time for a timer used for an autonomous measurement gap associated with a neighboring cell,
the autonomous measurement gap being autonomously determined by the UE;

initiating the timer;
determining that the autonomous measurement gap is to occur based at least in part on determining that the amount of time for the timer has expired; and
performing a measurement of the neighboring cell during the autonomous measurement gap.

13. The method of claim 12 , wherein determining the amount of time for the timer comprises:
determining the amount of time for the timer based on a point in time during which the UE typically enters an inactive state.

14. The method of claim 12 , wherein initiating the timer comprises:
initiating the timer at an end of a discontinuous reception (DRX) cycle.

15. The method of claim 12 , wherein determining that the autonomous measurement gap is to occur comprises:
determining that the amount of time for the timer has expired before the UE has transitioned from an active state of a discontinuous reception (DRX) cycle to an inactive state of the DRX cycle; and
determining, based on determining that the amount of time for the timer has expired before the UE has transitioned from the active state of the DRX cycle to the inactive state of the DRX cycle, that the autonomous measurement gap is to occur while the UE is in the active state of the DRX cycle.

16. The method of claim 15 , wherein the UE is in the active state of the DRX cycle after the amount of time for the timer has expired.

17. The method of claim 12 , wherein determining that the autonomous measurement gap is to occur comprises:
determining that the UE has transitioned from an active state of a discontinuous reception (DRX) cycle to an inactive state of the DRX cycle before the amount of time for the timer has expired; and
determining that the autonomous measurement gap is to occur before the amount of time for the timer has expired.

18. A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
determine an amount of time for a timer used for an autonomous measurement gap associated with a neighboring cell,
the autonomous measurement gap being autonomously determined by the UE;

initiate the timer;
determine that the autonomous measurement gap is to occur based at least in part on determining that the amount of time for the timer has expired; and
perform a measurement of the neighboring cell during the autonomous measurement gap.

19. The non-transitory computer-readable medium of claim 18 , wherein the amount of time for the timer is based on a point in time during which the UE typically enters an inactive state.

20. The non-transitory computer-readable medium of claim 18 , wherein the timer is initiated at an end of a discontinuous reception (DRX) cycle.
