Abstract
Certain aspects of the present disclosure provide techniques for configuring beam failure recovery operations. A method includes performing beam failure detection of a beam pair link associated with a secondary cell, wherein a user equipment (UE) is configured with one or more uplink control channel groups, each of the one or more uplink control channel groups comprising a corresponding plurality of component carriers where one of the corresponding plurality of component carriers is designated for communication of an uplink control channel for the corresponding uplink control channel group; determining one or more cells on which to send a beam failure recovery request (BFRQ) message based on a number of uplink control channel groups the UE is configured with; sending the BFRQ on the one or more cells; and receiving a beam failure recovery response message on at least one of the one or more cells.
