Original Abstract Submitted
The present disclosure relates to techniques that enable an efficient Radio Link Monitoring (RLM) for a User Equipment (UE) in a multi Transmitter Receiver Point (mTRP) scenario. For this purpose, a serving cell of a serving Distributed Unit (DU) of a disaggregated network node and at least one non-serving (or stand-by) cell of a non-serving DU of the disaggregated network node are configured fora UE. Then, the UE is informed of beams used for the serving and non-serving cells. The UE performs the RLM over the serving cell by using the beams of the serving cell. Whenever there is an Radio Link (RL) quality degradation (which may potentially lead to an RL Failure (RLF)) detected in the serving cell, the UE may initiate switching of the RLM from the serving cell to one of the non-serving cells by transmitting a corresponding request to the serving DU.
