Abstract

Methods, systems, and devices for wireless communication are described for improved scheduling and/or scheduling configuration. A base station may receive, from a user equipment (UE), an indication of one or more UE capabilities. The base station may determine, based on the one or more UE capabilities, when a grant to be transmitted is usable by the UE. The base station may transmit the grant to the UE, the grant including an assignment of resources based on when the grant is usable. In some examples, a UE may identify one or more UE capabilities in association with different grant characteristics and transmit, to a base station, an indication of the one or more UE capabilities. The UE may receive, from the base station, a grant having one of the different grant characteristics and including an assignment of resources, the assignment of resources based on the one or more UE capabilities.

Claims (63)

wherein determining when the grant is usable includes determining a time duration after receipt of the grant in which the grant is usable by the UE, and wherein determining the time duration comprises identifying the time duration based at least in part on a configuration of a wireless communications frame structure or slot in which the grant is to be transmitted, a configuration of a predetermined number of wireless communication frame structures or slots which follow transmission of the grant, or combinations thereof.

2. The method of claim 1 , wherein receiving the indication of the one or more UE capabilities further comprises:

receiving a capability table from the UE, wherein the capability table maps the one or more UE capabilities and one or more grant characteristics with an index.

3. The method of claim 1 , wherein determining when the grant is usable includes determining a time duration after receipt of the grant in which the grant is usable by the UE, the method further comprising:

selecting the time duration from a plurality of time durations corresponding to different at least one of the one or more UE capabilities or one or more grant characteristics.

4. The method of claim 1 , wherein determining when the grant is usable includes determining a time delay after which the UE is to respond to a downlink (DL) packet associated with the grant.

5. The method of claim 1 , wherein determining when the grant is usable includes determining a time duration after receipt of the grant in which the grant is usable by the UE, and wherein the time duration is in terms of at least one of time, one or more mini-slots, one or more slots, or one or more subframes.

6. The method of claim 1 , wherein determining when the grant is usable includes determining a time duration after receipt of the grant in which the grant is usable by the UE, and wherein determining the time duration comprises identifying the time duration based at least in part on whether the grant includes a beam indication, a beam-change indication, a bandwidth-part indication, a bandwidth-part change indication, or any combination thereof.

7. The method of claim 1 , wherein the time duration is based at least in part on whether the wireless communications frame structure or slot is of a downlink (DL) centric configuration or an uplink (UL) centric configuration.

8. The method of claim 1 , wherein the time duration is based at least in part on whether the wireless communications frame structure or slot includes a predetermined range of orthogonal frequency-division multiplexing (OFDM) symbols for downlink (DL) control, one or more sounding reference signals (SRSs) at the beginning of an uplink portion of the slot, or combinations thereof.

9. The method of claim 1 , further comprising:

receiving the indication of the one or more UE capabilities semi-statically in a UE capability table.

10. The method of claim 1 , further comprising:

receiving the indication of the one or more UE capabilities semi-statically in connection with a radio resource control (RRC) connection setup procedure or an RRC reconfiguration procedure.

11. The method of claim 1 , further comprising:

receiving the indication of the one or more UE capabilities via an uplink (UL) control channel from the UE.

12. The method of claim 1 , wherein the indication of the one or more UE capabilities is based at least in part on a history of at least one of one or more timing adjust durations received by the UE, or one or more hybrid automatic repeat request (HARQ) acknowledgements or negative acknowledgements received by the UE.

13. The method of claim 1 , wherein the indication of the one or more UE capabilities is based at least in part on one of a processing mode of the UE, available battery power of the UE, or available processing resources of the UE.

14. The method of claim 13 , wherein the processing mode of the UE is either a low-latency mode or a relaxed-processing mode.

15. A method for wireless communication by a user equipment (UE), comprising:

identifying one or more UE capabilities in association with different grant characteristics;

transmitting, to a base station, an indication of the one or more UE capabilities; and

receiving, from the base station, a grant having one of the different grant characteristics and including an assignment of resources, the assignment of resources based at least in part on the one or more UE capabilities

wherein the different grant characteristics include a configuration of a wireless communications frame structure or slot in which the grant is to be received.

16. The method of claim 15 , further comprising:

building a capability table, wherein the capability table maps UE capabilities and grant characteristics with an index; and

transmitting the capability table to the base station as the indication of a UE capability.

17. The method of claim 16 , wherein the capability table includes a time when the UE is able to process a grant having one or more of the grant characteristics.

18. The method of claim 15 , wherein the different grant characteristics include a beam indication, a beam-change indication, a bandwidth-part indication, a bandwidth-part change indication, or any combination thereof.

19. The method of claim 15 , further comprising:

transmitting the indication of the one or more UE capabilities semi-statically in a form of a UE capability table.

20. The method of claim 15 , further comprising:

transmitting the indication of the one or more UE capabilities semi-statically in connection with radio resource control (RRC) connection setup procedure or RRC reconfiguration procedure.

21. The method of claim 15 , further comprising:

transmitting the indication of the one or more UE capabilities via an uplink (UL) control channel from the UE.

22. The method of claim 15 , wherein the indication of the one or more UE capabilities is based at least in part on a history of at least one of one or more timing adjust durations received by the UE, or one or more hybrid automatic repeat request (HARQ) acknowledgements or negative acknowledgements received by the UE.

23.
