1. A scheduled entity in a wireless communication network, comprising:
a wireless transceiver;
a memory; and
a processor communicatively coupled to the wireless transceiver and the memory, wherein the processor and the memory are configured to:
receive a respective transmission reception point (TRP)-specific beam failure detection reference signal (BFD-RS) and a respective TRP identifier (ID) associated with each of a plurality of active beams received by the scheduled entity;
store, at a first layer of the scheduled entity, the respective TRP ID associated with each respective TRP-specific BFD-RS measurement that is less than a predetermined value; and
send respective TRP-specific signaling including the respective TRP ID associated with each respective TRP-specific BFD-RS measurement that is less than the predetermined value from the first layer of the scheduled entity to a second layer of the scheduled entity, wherein the second layer is higher than the first layer; and
transmit a beam failure recovery request (BFRQ) associated with the respective TRP ID to a scheduling entity in response to a predetermined quantity of respective TRP-specific BFD-RS measurements of at least one of the respective TRP-specific BFD-RS being less than the predetermined value.
