Abstract

Claims (81)

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

a memory; and

one or more processors coupled to the memory, wherein the UE is configured to:

activate a first bandwidth part (BWP), of a set of candidate BWPs, having a first bandwidth size; and

receive, based at least in part on an average buffer status report (BSR) index, of one or more BSRs transmitted by the UE, satisfying a BSR threshold for a time period, an indication to activate a second BWP, of the set of candidate BWPs, having a second bandwidth size.

2 . The UE of claim 1 , wherein, to activate the first BWP, the UE is configured to monitor resources within the first BWP for a control message, and

wherein, to activate the second BWP, the one or more processors, when activating the second BWP, configure the UE is configured to monitor the second BWP for a control message.

3 . The UE of claim 1 ,

wherein the UE is configured to deactivate the first BWP in association with activating the second BWP.

4 . The UE of claim 1 wherein the UE is further configured to:

activate the first BWP, after activating the second BWP, based at least in part on one or more of:

reception of an indication to activate the first BWP, or

satisfaction of a BWP switching time.

5 . The UE of claim 1 ,

wherein the UE is further configured to:

receive a BWP configuration that indicates configurations of the set of candidate BWPs.

6 . The UE of claim 1 ,

wherein the UE is further configured to:

transmit the one or more BSRs that include BSR indices to indicate whether the UE has data buffered for transmission.

7 . The UE of claim 6 , wherein, to transmit the one or more BSRs, the UE is configured to transmit the one or more BSRs via medium access control signaling.

8 . The UE of claim 1 ,

wherein the first bandwidth size is a largest bandwidth size of bandwidth sizes of the candidate BWPs.

9 . The UE of claim 1 ,

wherein satisfaction of the BSR threshold for the time period comprises the average BSR index being less than the BSR threshold, and

wherein the first bandwidth size is larger than the second bandwidth size.

10 . The UE of claim 1 ,

wherein satisfaction of the BSR threshold for the time period comprises the average BSR index being greater than the BSR threshold, and

wherein the second bandwidth size is larger than the first bandwidth size.

11 . The UE of claim 1 ,

wherein the BSR threshold is based at least in part on traffic conditions of a cell associated with a base station that is associated with the indication to activate the second BWP.

12 . The UE of claim 1 , wherein, to receive the indication to activate the second BWP, the UE is configured to:

receive the indication to activate the second BWP via one or more of downlink control information, medium access control signaling, or radio resource control signaling.

13 . The UE of claim 1 ,

wherein the UE is further configured to:

receive a control message via resources of the second BWP based at least in part on receiving the indication for the UE to activate the second BWP.

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

activating a first bandwidth part (BWP), of a set of candidate BWPs, having a first bandwidth size; and

receiving, based at least in part on an average buffer status report (BSR) index, of one or more BSRs transmitted by the UE, satisfying a BSR threshold for a time period, an indication to activate a second BWP, of the set of candidate BWPs, having a second bandwidth size.

15 . The method of claim 14 ,

wherein activating the first BWP comprises configuring the UE to monitor resources within the first BWP for a control message, and

wherein activating the second BWP comprises configuring the UE to monitor the second BWP for a control message.

16 . The method of claim 14 , further comprising

deactivating the first BWP in association with activating the second BWP.

17 . The method of claim 14 , further comprising:

activating the first BWP, after activating the second BWP, based at least in part on one or more of:

reception of an indication to activate the first BWP, or

satisfaction of a BWP switching time.

18 . The method of claim 14 , further comprising:

receiving a BWP configuration that indicates configurations of the set of candidate BWPs.

19 . The method of claim 14 , further comprising:

transmitting the one or more BSRs that include BSR indices to indicate whether the UE has data buffered for transmission.

20 . The method of claim 19 ,

wherein transmitting the one or more BSRs comprises transmitting the one or more BSRs via medium access control signaling.

21 . The method of claim 14 ,

wherein the first bandwidth size is a largest bandwidth size of bandwidth sizes of the candidate BWPs.

22 . The method of claim 14 ,

wherein satisfaction of the BSR threshold for the time period comprises the average BSR index being less than the BSR threshold, and

wherein the first bandwidth size is larger than the second bandwidth size.

23 . The method of claim 14 ,

wherein satisfaction of the BSR threshold for the time period comprises the average BSR index being greater than the BSR threshold, and

wherein the second bandwidth size is larger than the first bandwidth size.

24 . The method of claim 14 ,

wherein the BSR threshold is based at least in part on traffic conditions of a cell associated with a base station that is associated with the indication to activate the second BWP.

25 . The method of claim 14 ,

wherein receiving the indication to activate the second BWP comprises:

receiving the indication to activate the second BWP via one or more of downlink control information, medium access control signaling, or radio resource control signaling.

26 . The method of claim 14 , further comprising:

receiving a control message via resources of the second BWP based at least in part on receiving the indication for the UE to activate the second BWP.

27 . A non-transitory computer-readable medium having a set of instructions stored thereon 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:

activate a first bandwidth part (BWP), of a set of candidate BWPs, having a first bandwidth size; and

receive, based at least in part on an average buffer status report (BSR) index, of one or more BSRs transmitted by the UE, satisfying a BSR threshold for a time period, an indication to activate a second BWP, of the set of candidate BWPs, having a second bandwidth size.
