Method, apparatus, and system utilizing lower layer signalling for mobility beam management

Methods and devices are provided that use lower-layer signalling, for example Layer 1 (L1) and/or Layer 2 (L2), as a part of mobility beam management. A method for performing inter-cell mobility management may include receiving, by a user equipment (UE) from a network, higher-layer signaling that includes configuration information for a plurality of mobility beam management reference signals (MBM-RSs) enabling the UE to measure MBM-RSs transmitted by at least one base station in the network. In addition the UE may receive from the network, lower-layer signaling include additional information relating to monitoring for a mobility beam MBM event.
