  • RRM Radio Resource Management
  • a system can request a terminal device (or user equipment, UE) to measure SSBs and/or CSI-RS for mobility of multiple neighbor cells.

  • One drawback in the traditional method is relying on RRC signaling to perform RRM measurements.
  • a terminal device performs L3 measurement and then reports a measurement result through RRC signaling.
  • the latency and overhead of the RRM measurement is large.
  • the traditional RRM measurement is not capable of assisting Layer- 1 /Layer-2 (L1/L2) based inter-cell mobility.
  • Another drawback is that the conventional function of measuring L1- RSRP of SSBs of different Physical Cell ID (PCI) assumes all the SSBs are on the same frequency and uses the same subcarrier spacing as a serving cell. Therefore, it is not able to support inter-cell mobility scenarios where a target cell is on different frequency, or uses different subcarrier spacing, or is not synchronized with the serving cell. Thus, improved systems and methods that can address the foregoing issues are desirable and beneficial.
