Radio beam failure recovery procedure timing
A wireless device receives one or more messages comprising configuration parameters indicating a timer value of a bandwidth part (BWP) inactivity timer. The BWP inactivity timer associated with the timer value is started in response to switching to a first BWP as an active BWP. A random-access procedure for a beam failure recovery is initiated based on reaching a number of beam failure instance indications for at least one downlink control channel of the first BWP. The BWP inactivity timer is stopped based on initiating the random-access procedure. The at least one downlink control channel is monitored for a control information addressed to the wireless device. The random-access procedure for the beam failure recovery is stopped in response to receiving the control information via the at least one downlink control channel. The BWP inactivity timer is restarted based on the stopping the random-access procedure.
1. A method comprising:
receiving, by a wireless device, one or more messages comprising configuration parameters indicating a timer value of a bandwidth part (BWP) inactivity timer;
starting the BWP inactivity timer associated with the timer value in response to switching to a first BWP as an active BWP;
initiating a beam failure recovery procedure based on reaching a number of beam failure instance indications for at least one downlink control channel of the first BWP;
based on the initiating the beam failure recovery procedure, stopping the BWP inactivity timer;
monitoring the at least one downlink control channel for a control information addressed to the wireless device;
stopping the beam failure recovery procedure, before the beam failure recovery procedure completes, in response to receiving the control information via the at least one downlink control channel; and
restarting the BWP inactivity timer based on the stopping the beam failure recovery procedure.
2. The method of claim 1 , wherein the first BWP is a non-default BWP.
3. The method of claim 1 , wherein the configuration parameters further indicate one or more reference signals for the first BWP.
4. The method of claim 3 , wherein the one or more reference signals comprise:
one or more channel state information reference signals; or
one or more synchronization signal/physical broadcast channel blocks.
5. The method of claim 1 , wherein a beam failure instance indication of the beam failure instance indications comprises an assessment of one or more reference signals with radio quality lower than a threshold.
6. The method of claim 5 , wherein the configuration parameters further indicate the threshold.
7. The method of claim 1 , wherein the restarting the BWP inactivity timer further comprises restarting the BWP inactivity timer based on the timer value.
8. The method of claim 1 , wherein the control information comprises an uplink grant or a downlink assignment.
9. The method of claim 1 , wherein the switching to the first BWP as the active BWP is based on receiving a downlink control information indicating the first BWP.
10. The method of claim 1 , wherein the instructions, when executed by the one or more processors, further cause the wireless device to monitor a dedicated control resource set for a second control information for the beam failure recovery.
11. The method of claim 1 , wherein the control information is addressed to a configured scheduling radio network temporary identifier of the wireless device.
12. The method of claim 1 , further comprising switching from the first BWP to a second BWP based on the control information indicating the second BWP.
13. The method of claim 1 , further comprising monitoring a dedicated control resource set for a second control information for the beam failure recovery.
14. 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 messages comprising configuration parameters indicating a timer value of a bandwidth part (BWP) inactivity timer;
start the BWP inactivity timer associated with the timer value in response to switching to a first BWP as an active BWP;
initiate a beam failure recovery procedure based on reaching a number of beam failure instance indications for at least one downlink control channel of the first BWP;
based on initiating the beam failure recovery procedure, and stop the BWP inactivity timer;
monitor the at least one downlink control channel for a control information addressed to the wireless device;
stop the beam failure recovery procedure, before the beam failure recovery procedure completes, in response to receiving the control information via the at least one downlink control channel; and
restart the BWP inactivity timer based on the stopping the beam failure recovery procedure.
