Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that the UE is in an active communication session using a first radio access technology (RAT), wherein the UE is operating in a dual connectivity mode that uses a master cell group for the first RAT and a secondary cell group for a second RAT; determine that the UE is configured with a maximum transmit power, for the first RAT in the dual connectivity mode, that is less than a maximum transmit power threshold; determine that at least one of a power headroom (PHR) value or an estimated uplink block error rate (BLER) satisfies a condition; and transmit an indication that the secondary cell group has failed based at least in part on those determinations. Numerous other aspects are provided.
