Abstract
Embodiments include methods for a user equipment (UE) configured to communicate with a radio access network (RAN) via a master cell group (MCG) and a secondary cell group (SCG). Such methods include, while the SCG is deactivated, performing beam failure detection (BFD) for at least one cell in the SCG, according to a first BFD configuration. Such methods include, in response to detecting an initial beam failure in the deactivated SCG, transmitting a first message indicating the initial beam failure to a RAN node configured to provide the MCG; and in response to detecting one or more subsequent beam failures in the deactivated SCG, refraining from transmitting to the RAN any messages indicating the one or more subsequent beam failures (e.g., until receiving another BFD configuration). Other embodiments include complementary methods for a RAN node, as well as UEs and RAN nodes configured to perform such methods.
