Abstract

A method may include determining, by a wireless device, a periodic beam failure detection (BFD) reference signal (RS) is not received due to a failure of a listen before talk (LBT) procedure. The method may include transmitting, in response to the determining, a message for a BFD procedure based on receiving an aperiodic BFD RS quasi collocated with the periodic BFD RS.

Claims (40)

1. A method comprising:

receiving, by a wireless device, one or more first messages indicating:

a periodic beam failure (BFD) reference signals (RSs);

an aperiodic BFD RS; and

a channel occupancy time (COT) duration for receiving the aperiodic BFD RS;

determining, by the wireless device, the periodic BFD RS is not received due to a failure of a listen before talk (LBT) procedure; and

transmitting, in response to the determining and based on the COT duration, a second message, for a BFD procedure, indicating the aperiodic BFD RS, wherein the aperiodic BFD RS is quasi collocated with the periodic BFD RS.

2. The method of claim 1 , wherein the one or more first messages further indicate the aperiodic BFD RS is quasi collocated with the periodic BFD RS.

3. The method of claim 1 , further comprising receiving, from a base station, the aperiodic BFD RS within the COT duration starting from an end of a last symbol of the periodic BFD RS.

4. The method of claim 1 , further comprising receiving, from a base station, the aperiodic BFD RS within a frequency range starting from an end of a last resource block of the periodic BFD RS.

5. The method of claim 1 , wherein the determining the periodic BFD RS is not received due to the failure of the LBT procedure is based on measurements of channel quality of the periodic BFD RS and the aperiodic BFD RS.

6. The method of claim 1 , wherein the determining the periodic BFD RS is not received due to the failure of the LBT procedure is based on an indication from downlink control information.

7. The method of claim 1 , further comprising receiving, from a base station, the aperiodic BFD RS in response to the determining the periodic BFD RS is not received due to the failure of the LBT procedure.

8. The method of claim 1 , further comprising determining the aperiodic BFD RS, from a plurality of aperiodic BFD RSs, is associated with the periodic BFD RS.

9. The method of claim 1 , further comprising indicating a beam failure instance, from a physical layer of the wireless device to medium access control layer of the wireless device, based on the aperiodic BFD RS.

10. The method of claim 1 , wherein the second message comprises a beam failure recovery request.

11. 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 one or more first messages indicating:

a periodic beam failure (BFD) reference signals (RSS);

an aperiodic BFD RS; and

a channel occupancy time (COT) duration for receiving the aperiodic BFD RS;

determine the periodic BFD RS is not received due to a failure of a listen before talk (LBT) procedure; and

transmit, in response to not receiving the periodic BFD RS and based on the COT duration, a second message, for a BFD procedure, indicating the aperiodic BFD RS, wherein the aperiodic BFD RS is quasi collocated with the periodic BFD RS.

12. The wireless device of claim 11 , wherein the one or more first messages further indicate the aperiodic BFD RS is quasi collocated with the periodic BFD RS.

13. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, from a base station, the aperiodic BFD RS within the COT duration starting from an end of a last symbol of the periodic BFD RS.

14. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, from a base station, the aperiodic BFD RS within a frequency range starting from an end of a last resource block of the periodic BFD RS.

15. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine the periodic BFD RS is not received due to the failure of the LBT procedure based on measurements of channel quality of the periodic BFD RS and the aperiodic BFD RS.

16. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine the periodic BFD RS is not received due to the failure of the LBT procedure based on an indication from downlink control information.

17. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to receive, from a base station, the aperiodic BFD RS in response to determining the periodic BFD RS is not received due to the failure of the LBT procedure.

18. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to determine the aperiodic BFD RS, from a plurality of aperiodic BFD RSs, is associated with the periodic BFD RS.

19. The wireless device of claim 11 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to indicate a beam failure instance, from a physical layer of the wireless device to medium access control layer of the wireless device, based on the aperiodic BFD RS.

20. A non-transitory computer-readable medium comprising instructions that, when executed by one or more processors, cause the one or more processors to:

receive one or more first messages indicating:

a periodic beam failure (BFD) reference signals (RSs);

an aperiodic BFD RS; and

a channel occupancy time (COT) duration for receiving the aperiodic BFD RS;

determine the periodic BFD RS is not received due to a failure of a listen before talk (LBT) procedure; and

transmit, in response to not receiving the periodic BFD RS and based on the COT duration, a second message, for a BFD procedure, indicating the aperiodic BFD RS, wherein the aperiodic BFD RS is quasi collocated with the periodic BFD RS.
