Wireless resource switching
Wireless communications may comprise communications between a base station and a wireless device. Wireless resources, such as bandwidth parts, may be used for the wireless communications. Based on a determination to switch a wireless resource, another wireless resource may be activated within a time duration. The time duration may be based on whether the wireless resource to be activated and the wireless device to be switched are in a same group of wireless resources.
1. A method comprising:
receiving, by a wireless device, configuration parameters indicating a plurality of bandwidth parts (BWPs), wherein the plurality of BWPs are grouped into at least one bandwidth part (BWP) group and wherein the plurality of BWPs comprises a first BWP and a second BWP; and
switching from the first BWP to the second BWP as an active BWP, wherein activation of the second BWP is during a BWP activation time window that has:
a first duration if the first BWP and the second BWP are in a same BWP group of the at least one BWP group; or
a second duration, different from the first duration, if the first BWP and the second BWP are not in the same BWP group.
2. The method of claim 1 , further comprising sending, based on an expiration of the BWP activation time window, a signal via the second BWP.
3. The method of claim 1 , wherein the BWP activation time window is further based on a numerology of one or both of the first BWP or the second BWP.
4. The method of claim 1 , further comprising sending information indicating one of a plurality of BWP switching delay types, wherein the BWP activation time window is further based on the one of the plurality of BWP switching delay types.
5. The method of claim 1 , wherein the first duration is shorter than the second duration.
6. The method of claim 1 , wherein at least one of the configuration parameters indicates the at least one BWP group.
7. The method of claim 1 , wherein the switching comprises maintaining for the second BWP, based on the first BWP and the second BWP being in the same BWP group, activation of at least one configuration of the first BWP.
8. A method comprising:
sending, by a base station, configuration parameters indicating a plurality of bandwidth parts (BWPs), wherein the plurality of BWPs are grouped into at least one bandwidth part (BWP) group and wherein the plurality of BWPs comprises a first BWP and a second BWP; and
switching from the first BWP to the second BWP as an active BWP, wherein activation of the second BWP is during a BWP activation time window that has:
a first duration if the first BWP and the second BWP are in a same BWP group of the at least one BWP group; or
a second duration, different from the first duration, if the first BWP and the second BWP are not in the same BWP group.
9. The method of claim 8 , wherein the BWP activation time window is further based on a numerology of one or both of the first BWP or the second BWP.
10. The method of claim 8 , further comprising receiving information indicating a BWP switching delay type associated with a wireless device, wherein the BWP activation time window is further based on the one of the plurality of BWP switching delay types.
11. The method of claim 8 , wherein the first duration is shorter than the second duration.
12. The method of claim 8 , wherein at least one of the configuration parameters indicates the at least one BWP group.
13. The method of claim 8 , wherein switching comprises maintaining for the second BWP, based on the first BWP and the second BWP being in the same BWP group, activation of at least one configuration of the first BWP.
14. The method of claim 8 , further comprising determining, based on one or more configurations common to at least some of the plurality of BWPs, which of the plurality of BWPs are in the at least one BWP group.
15. A method comprising:
determining, by a device comprising one or more antennas, a plurality of bandwidth part (BWP) groups;
sending, via a first BWP of the plurality of BWP groups and using the one or more antennas, a transmission;
activating, during a BWP activation time window, a second BWP, wherein the BWP activation time window has:
a first duration if the first BWP and the second BWP are in a same BWP group of the plurality of BWP groups; or
a second duration, different from the first duration, if the first BWP and the second BWP are not in the same BWP group; and
sending, via the second BWP and after an expiration of the BWP activation time window, a second transmission.
16. The method of claim 15 , wherein the device comprises at least one of: a wireless device or a base station.
17. The method of claim 15 , further comprising:
deactivating at least one configuration of the first BWP; and
maintaining, based on the first BWP and the second BWP being in the same BWP group, activation of at least a second portion of configurations of the first BWP.
18. The method of claim 15 , wherein the BWP activation time window is further based on a numerology of one or both of the first BWP or the second BWP.
19. The method of claim 15 , further comprising sending or receiving, using the one or more antennas, configuration parameters indicating the first BWP, the second BWP, and the plurality of BWP groups.
20. The method of claim 15 , wherein the BWP activation time window is further based on a switching delay type associated with a wireless device.
21. The method of claim 15 , wherein the first duration is shorter than the second duration.
