Abstract
An aspect of the present disclosure includes methods, systems, and computer-readable media for receiving a beam failure detection reference signal configuration, detecting an absence of a configured and quasi-co-located beam failure detection reference signal in a monitored control resource set (CORESET), and utilizing reference signals indicated in the CORESET transmission configuration indicator state for beam failure detection.
Claims24
A method of wireless communication, comprising:
- receiving a beam failure detection (BFD) reference signal (RS) configuration;
- detecting an absence of a configured and quasi-co-located BFD RS in at least one monitored control resource set (CORESET);
- and
- utilizing one or more RSs indicated in a CORESET transmission configuration indicator (TCI) state for beam failure detection.
A method of wireless communication, comprising:
- receiving a BFD RS configuration;
- detecting an absence of a configured and quasi-co-located BFD RS in at least one monitored CORESET;
- and
- utilizing one or more demodulation RSs of the at least one monitored CORESET or decoding statistics of a physical downlink control channel (PDCCH) carried by the at least one monitored CORESET to evaluate a CORESET quality for beam failure detection.
A method of wireless communication, comprising:
- receiving a BFD RS configuration;
- waiting until a configuration of a corresponding quasi-co-located BFD RS in a monitored CORESET is complete;
- and
- utilizing the corresponding quasi-co-located BFD RS for beam failure detection.
A user equipment, comprising:
- a memory;
- a transceiver;
- one or more processors operatively coupled with the memory and the transceiver, the one or more processors configured to perform the steps of:
- receiving, via the transceiver, a beam failure detection (BFD) reference signal (RS) configuration;
- detecting an absence of a configured and quasi-co-located BFD RS in at least one monitored control resource set (CORESET);
- and
- utilizing one or more RSs indicated in a CORESET transmission configuration indicator (TCI) state for beam failure detection.
