Abstract
A User equipment (UE) receives a control resource set (CORESET) configuration for a full duplex CORESET. The UE performs a measurement for full duplex operation based on at least one of a downlink beam or an uplink beam for full duplex beam failure detection based on one or more quasi co-location (QCL) relationships to one or more transmission configuration indication (TCI) states of the CORESET based on an absence of a configuration of a reference signal for the full duplex beam failure detection.
Claims25
An apparatus for wireless communication at a user equipment (UE), comprising:
- at least one memory;
- and
- one or more processors coupled to the at least one memory, the one or more processors being configured to:
- receive a control resource set (CORESET) configuration for a full duplex CORESET;
- perform a measurement for full duplex operation based on at least one of a downlink beam or an uplink beam for full duplex beam failure detection having one or more quasi co-location (QCL) relationships to one or more transmission configuration indication (TCI) states of the full duplex CORESET and based on an absence of a configuration of a reference signal for the full duplex beam failure detection;
- determine at least one downlink reference signal for the full duplex beam failure detection based on the downlink beam having a QCL type D relationship to the one or more TCI states of the full duplex CORESET;
- and
- determine the uplink beam is paired with the downlink beam having the QCL type D relationship to the one or more TCI states of the full duplex CORESET.
