Abstract
In accordance with some aspects, a method of wireless communication performed by a user equipment (UE) is disclosed. The method includes monitoring for beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell, the group of beams associated with a group beam identifier; measuring, based on the monitoring for the BFD RSs, a reference signal received power (RSRP) of one or more of the BFD RSs; and triggering, based on the RSRP being below a threshold, a beam failure recovery (BFR) process for the group of beams.

A method of wireless communication performed by a user equipment (UE), the method comprising:
- monitoring for beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell, the group of beams associated with a group beam identifier;
- measuring, based on the monitoring for the BFD RSs, a reference signal received power (RSRP) of one or more of the BFD RSs;
- and
- triggering, based on the RSRP being below a threshold, a beam failure recovery (BFR) process for the group of beams.
A user equipment (UE), comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- monitor for beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell, the group of beams associated with a group beam identifier;
- measure, based on the monitoring for the BFD RSs, a reference signal received power (RSRP) of one or more of the BFD RSs;
- and
- trigger, based on the RSRP being below a threshold, a beam failure recovery (BFR) process for the group of beams.
A method of wireless communication performed by a base station (BS), comprising:
- transmitting, to a user equipment (UE), at least one DCI communication with an indication of beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell;
- transmitting the BFD RSs to the UE;
- and
- receiving from the UE a beam failure recovery (BFR) message.
A base station (BS), comprising:
- a memory;
- and
- a transceiver coupled to the memory and configured to:
- transmit, to a user equipment (UE), at least one DCI communication with an indication of beam failure detection (BFD) reference signals (RSs) for a group of beams of a serving cell;
- transmit the BFD RSs to the UE;
- and
- receive from the UE a beam failure recovery (BFR) message.
