Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive uplink frames delivered from an application of the UE. The UE may transmit a message that indicates one or more of a cadence of the uplink frames or an offset of each of the uplink frames. The UE may receive an uplink transmission configuration that indicates that uplink transmission occasions of the UE are to overlap with power efficient opportunities. The UE may transmit uplink transmissions for the uplink frames at the uplink transmission occasions according to the uplink transmission configuration. Numerous other aspects are described.

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:
receive uplink frames delivered from an application of the UE;
transmit a message that indicates one or more of a cadence of the uplink frames or an offset of each of the uplink frames;
receive an uplink transmission configuration that indicates that uplink transmission occasions of the UE are to overlap with power efficient opportunities; and
transmit uplink transmissions for the uplink frames at the uplink transmission occasions according to the uplink transmission configuration.

2 . The UE of claim 1 , wherein the power efficient opportunities include downlink data reception occasions.

3 . The UE of claim 1 , wherein the power efficient opportunities include transmission occasions in a low power bandwidth part.

4 . The UE of claim 1 , wherein the power efficient opportunities include connected discontinuous reception on durations.

5 . The UE of claim 1 , wherein the uplink transmission configuration indicates that the UE is to aggregate multiple uplink frames into an uplink transmission.

6 . The UE of claim 1 , wherein the uplink transmission configuration includes one or more of an uplink configured grant (CG) cadence that is based at least in part on the cadence of the uplink frames or an uplink CG offset that is based at least in part on the offset of each of the uplink frames.

7 . The UE of claim 1 , wherein the message includes one or more of a suggested uplink configured grant (CG) cadence for uplink transmission occasions that is based at least in part on the cadence of the uplink frames or a suggested uplink CG offset for uplink transmission occasions that is based at least in part on the offset of each of the uplink frames.

8 . The UE of claim 7 , wherein the one or more processors, to transmit the message, are configured to transmit the message in a radio resource control message.

9 . The UE of claim 7 , wherein the one or more processors, to transmit the message, are configured to transmit the message in a medium access control control element (MAC CE).

10 . The UE of claim 9 , wherein the one or more of the suggested uplink CG cadence or the suggested uplink CG offset is for a single uplink CG.

11 . The UE of claim 9 , wherein the message includes multiple suggested uplink CG cadences or multiple suggested uplink CG offsets for multiple uplink CGs.

12 . The UE of claim 1 , wherein the one or more processors, to receive the uplink transmission configuration, are configured to receive the uplink transmission configuration in a medium access control control element (MAC CE).

13 . The UE of claim 12 , wherein the uplink transmission configuration indicates a ratio of a cadence of uplink transmission occasions in relation to the cadence of the uplink frames.

14 . The UE of claim 12 , wherein the uplink transmission configuration is for a single uplink configured grant.

15 . The UE of claim 12 , wherein the uplink transmission configuration is for multiple uplink configured grants.

16 . The UE of claim 12 , wherein the uplink transmission configuration activates or deactivates one or more uplink CGs.

17 . The UE of claim 1 , wherein the message includes a buffer status report that excludes stored service data units and stored protocol data units that are associated with stored uplink frames from a data volume calculation if a quantity of the stored uplink frames does not satisfy an uplink frame threshold.

18 . A base station for wireless communication, comprising:
a memory; and one or more processors, coupled to the memory, configured to:
receive, from a user equipment (UE), a message that indicates one or more of a cadence of uplink frames for an application of the UE or an offset of each of the uplink frames;
generate an uplink transmission configuration for the UE based at least in part on the one or more of the cadence of the uplink frames or the offset for each of the uplink frames, such that uplink transmission occasions of the UE overlap with power efficient opportunities;
transmit the uplink transmission configuration to the UE; and
receive uplink transmissions at the uplink transmission occasions according to the uplink transmission configuration.

19 . The base station of claim 18 , wherein the power efficient opportunities include one or more of downlink data reception occasions, transmission occasions in a low power bandwidth part, or connected discontinuous reception on durations.

20 . The base station of claim 18 , wherein the uplink transmission configuration indicates that the UE is to aggregate multiple uplink frames into an uplink transmission.

21 . The base station of claim 18 , wherein the uplink transmission configuration includes one or more of an uplink configured grant (CG) cadence that is based at least in part on the cadence of the uplink frames or an uplink CG offset that is based at least in part on the offset of each of the uplink frames.

22 . The base station of claim 18 , wherein the message includes one or more of a suggested uplink configured grant (CG) cadence for uplink transmission occasions that is based at least in part on the cadence of the uplink frames or a suggested uplink CG offset for uplink transmission occasions that is based at least in part on the offset of each of the uplink frames, and wherein the one or more processors, to generate the uplink transmission configuration, are configured to generate the uplink transmission configuration based at least in part on the one or more of the suggested uplink CG cadence or the suggested uplink CG offset.

23 . The base station of claim 22 , wherein the one or more processors, to receive the message, are configured to receive the message in a radio resource control message.

24 . The base station of claim 22 , wherein the one or more processors, to receive the message, are configured to receive the message in a medium access control control element (MAC CE).

25 . The base station of claim 24 , wherein the one or more of the suggested uplink CG cadence or the suggested uplink CG offset is for a single uplink CG.

26 . The base station of claim 24 , wherein the message includes multiple suggested uplink CG cadences or multiple suggested uplink CG offsets for multiple uplink CGs.

27 . The base station of claim 18 , wherein the one or more processors, to transmit the uplink transmission configuration, are configured to transmit the uplink transmission configuration in a medium access control control element (MAC CE).
