Abstract

Claims (47)

1. A wireless device comprising:

one or more processors; and

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

receive a first message indicating a first transmission configuration indicator (TCI) state for receiving a downlink control channel;

after receiving the first message, receive a second message indicating a common TCI state for receiving the downlink control channel and a downlink shared channel; and

based on an end of a first application time of the first TCI state being later than an end of a second application time of the common TCI state, receive the downlink control channel using the first TCI state.

2. The wireless device of claim 1 , wherein the instructions further cause the wireless device to receive the downlink shared channel using the common TCI state.

3. The wireless device of claim 1 , wherein the instructions further cause the wireless device to ignore, based on the end of the first application time being later than the end of the second application time, the first message by not applying the common TCI state for receiving the downlink control channel.

4. The wireless device of claim 1 , wherein the first message comprises a medium access control (MAC) control element (CE) message.

5. The wireless device of claim 1 , wherein the second message comprises a downlink control information (DCI).

6. The wireless device of claim 1 , wherein:

the first application time is a first duration after the first message is received; and

the second application time is a second duration after the second message is received.

7. The wireless device of claim 1 , wherein:

the first application time comprises a first duration to decode the first message; and

the second application time comprises a second duration to decode the second message.

8. A base station comprising:

one or more processors; and

memory storing instructions that, when executed by the one or more processors, cause the base station to:

transmit, to a wireless device, a first message indicating a first transmission configuration indicator (TCI) state for receiving a downlink control channel;

after transmitting the first message, transmit, to the wireless device, a second message indicating a common TCI state for receiving the downlink control channel and a downlink shared channel; and

based on an end of a first application time of the first TCI state being later than an end of a second application time of the common TCI state, transmit, to the wireless device, the downlink control channel using the first TCI state.

9. The base station of claim 8 , wherein the instructions further cause the base station to transmit, to the wireless device, the downlink shared channel using the common TCI state.

10. The base station of claim 8 , wherein the instructions further cause the base station to ignore, based on the end of the first application time being later than the end of the second application time, the first message by not applying the common TCI state for transmitting the downlink control channel.

11. The base station of claim 8 , wherein the first message comprises a medium access control (MAC) control element (CE) message.

12. The base station of claim 8 , wherein the second message comprises a downlink control information (DCI).

13. The base station of claim 8 , wherein:

the first application time is a first duration after the first message is received by the wireless device; and

the second application time is a second duration after the second message is received by the wireless device.

14. The base station of claim 8 , wherein:

the first application time comprises a first duration for the wireless device to decode the first message; and

the second application time comprises a second duration for the wireless device to decode the second message.

15. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors of a wireless device, cause the wireless device to:

receive a first message indicating a first transmission configuration indicator (TCI) state for receiving a downlink control channel;

after receiving the first message, receive a second message indicating a common TCI state for receiving the downlink control channel and a downlink shared channel; and

based on an end of a first application time of the first TCI state being later than an end of a second application time of the common TCI state, receive the downlink control channel using the first TCI state.

16. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the wireless device to receive the downlink shared channel using the common TCI state.

17. The non-transitory computer-readable medium of claim 15 , wherein the instructions further cause the wireless device to ignore, based on the end of the first application time being later than the end of the second application time, the first message by not applying the common TCI state for receiving the downlink control channel.

18. The non-transitory computer-readable medium of claim 15 , wherein:

the first message comprises a medium access control (MAC) control element (CE) message; and

the second message comprises a downlink control information (DCI).

19. The non-transitory computer-readable medium of claim 15 , wherein:

the first application time is a first duration after the first message is received; and

the second application time is a second duration after the second message is received.

20. The non-transitory computer-readable medium of claim 15 , wherein:

the first application time comprises a first duration to decode the first message; and

the second application time comprises a second duration to decode the second message.
