Abstract

Claims (84)

1. A method comprising:

receiving, by a wireless device, one or more messages comprising information indicating a plurality of downlink channels associated with a plurality of power saving configurations;

receiving a first indication to activate a first power saving configuration of the plurality of power saving configurations;

monitoring, based on activation of the first power saving configuration, a first downlink channel, of the plurality of downlink channels, corresponding to the first power saving configuration; and

receiving, via the first downlink channel, a second indication to monitor a second downlink channel.

2. The method of claim 1 , further comprising:

receiving, based on monitoring the second downlink channel, downlink control information.

3. The method of claim 1 , further comprising:

receiving, based on monitoring the second downlink channel, a downlink assignment; and

receiving, based on the downlink assignment, downlink transport blocks.

4. The method of claim 1 , further comprising:

receiving, based on monitoring the second downlink channel, an uplink grant; and

transmitting, based on the uplink grant, uplink transport blocks.

5. The method of claim 1 , wherein:

the one or more messages comprise information associated with the first power saving configuration, wherein the information associated with the first power saving configuration comprises at least one of:

a periodicity of the first downlink channel,

a duration of the first downlink channel,

a number of resource blocks in a frequency domain,

a search space set, or

a control resource set; and

the monitoring the first downlink channel is based on at least one of the information associated with the first power saving configuration.

6. The method of claim 1 , further comprising:

determining, based on receiving a second message, that a beam failure recovery procedure is ongoing on a cell associated with the first power saving configuration; and

based on the determining that the beam failure recovery procedure is ongoing on the cell:

continuing the beam failure recovery procedure, and

delaying adjusting the cell into a power saving state.

7. The method of claim 1 , further comprising, based on receiving the first indication, at least one of:

stopping a secondary cell deactivation timer of a cell associated with the first power saving configuration; or

stopping a bandwidth part inactivity timer of an active bandwidth part of the cell associated with the first power saving configuration.

8. A wireless device comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, configure the wireless device to:

receive one or more messages comprising information indicating a plurality of downlink channels associated with a plurality of power saving configurations;

receive a first indication to activate a first power saving configuration of the plurality of power saving configurations;

monitor, based on activation of the first power saving configuration, a first downlink channel, of the plurality of downlink channels, corresponding to the first power saving configuration; and

receive, via the first downlink channel, a second indication to monitor a second downlink channel.

9. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to receive, based on monitoring the second downlink channel, downlink control information.

10. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to:

receive, based on monitoring the second downlink channel, a downlink assignment; and

receive, based on the downlink assignment, downlink transport blocks.

11. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to:

receive, based on monitoring the second downlink channel, an uplink grant; and

transmit, based on the uplink grant, uplink transport blocks.

12. The wireless device of claim 8 , wherein:

the one or more messages comprise information associated with the first power saving configuration, wherein the information associated with the first power saving configuration comprises at least one of:

a periodicity of the first downlink channel,

a duration of the first downlink channel,

a number of resource blocks in a frequency domain,

a search space set, or

a control resource set; and

the instructions, when executed by the one or more processors, configure the wireless device to monitor the first downlink channel based on at least one of the information associated with the first power saving configuration.

13. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to:

determine, based on receiving a second message, that a beam failure recovery procedure is ongoing on a cell associated with the first power saving configuration; and

based on determining that the beam failure recovery procedure being ongoing on the cell:

continue the beam failure recovery procedure, and

delay adjusting the cell into a power saving state.

14. The wireless device of claim 8 , wherein the instructions, when executed by the one or more processors, further configure the wireless device to, based on the first indication, perform at least one of:

stopping a secondary cell deactivation timer of a cell associated with the first power saving configuration, or

stopping a bandwidth part inactivity timer of an active bandwidth part of the cell associated with the first power saving configuration.

15. A non-transitory computer-readable medium storing instructions that, when executed, configure a wireless device to:

receive one or more messages comprising information indicating a plurality of downlink channels associated with a plurality of power saving configurations;

receive a first indication to activate a first power saving configuration of the plurality of power saving configurations;

monitor, based on activation of the first power saving configuration, a first downlink channel, of the plurality of downlink channels, corresponding to the first power saving configuration; and

receive, via the first downlink channel, a second indication to monitor a second downlink channel.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, further configure the wireless device to receive, based on monitoring the second downlink channel, downlink control information.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, further configure the wireless device to:

receive, based on monitoring the second downlink channel, a downlink assignment; and

receive, based on the downlink assignment, downlink transport blocks.

18. The non-transitory computer-readable medium of claim 15 , wherein the instructions, when executed, further configure the wireless device to:
