Method for response to beam failure recovery request
First Claim
Patent Images
1. A method for beam failure recovery in user equipment, comprising:
- sending a beam failure recovery request (BFRR) to a base station upon detection of a beam failure between the base station and the user equipment; and
monitoring one or more candidate beams in which to receive from the base station a BFRR response that is spatially quasi co-located with the BFRR, and the monitoring is performed with a time offset relative to the BFRR.

Abstract
The disclosure relates to technology for beam failure recovery in user equipment. The user equipment sends a beam failure recovery request to the base station upon detection of a beam failure between the base station and the user equipment, and monitors one or more candidate beams in which to receive the beam failure recovery request response from the base station, based on an association between a beam failure recovery request response and a beam failure recovery request.

17. A device, comprising:
-
a non-transitory memory storage comprising instructions; and one or more processors in communication with the memory, wherein the one or more processors execute the instructions to; send a beam failure recovery request (BFRR) to a base station upon detection of a beam failure between the base station and the device; and monitor one or more candidate beams in which to receive from the base station a BFRR response that is spatially quasi co-located with the BFRR, and the monitoring is performed with a time offset relative to the BFRR. - View Dependent Claims (18, 19, 20)

21. A non-transitory computer-readable medium storing computer instructions for beam failure recovery in user equipment, that when executed by one or more processors, cause the one or more processors to perform the steps of:
-
sending a beam failure recovery request (BFRR) to a base station upon detection of a beam failure between the base station and the user equipment; and monitoring one or more candidate beams in which to receive from the base station a BFRR response that is spatially quasi co-located with the BFRR, and the monitoring is performed with a time offset relative to the BFRR. - View Dependent Claims (22)

23. A method for handling beam failure recovery in a base station, comprising:
-
receiving a beam failure recovery request (BFRR) from a user equipment identifying a candidate beam; and transmitting a BFRR response associated with the received BFRR on the candidate beam for which the BFRR response is spatially quasi co-located with the BFRR, and the transmitting is performed with a time offset relative to the BFRR. - View Dependent Claims (24, 25, 26, 27)
