Title:
PER-TRANSMISSION AND RECEPTION POINT (TRP) BEAM FAILURE REPORTING
Document Type and Number:
WIPO Patent Application WO/2023/050263
Kind Code:
A1
Abstract:
This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for reporting, from a user equipment (UE), beam failure recovery (BFR) information for multiple transmission and reception points (TRPs) via a BFR medium access control (MAC) control element (MAC-CE) in multi-TRP deployment scenarios. In some aspects, the UE may monitor a beam failure status for each of a first TRP and a second TRP and may transmit a BFR MAC-CE if the UE detects a beam failure for the first TRP or the second TRP. The UE may include, in the BFR MAC-CE, a status indicator field that indicates the beam failure status for each of the first TRP and the second TRP and whether a candidate reference signal is reported for identified TRPs of the first TRP and the second TRP for which a beam failure is detected.
