  • Patent number: 10972926
    Abstract: Apparatus and methods are provided to for RRM measurement in the new radio (NR) access system. In one novel aspect, multiple transmission (TX) beams are measured by a user equipment (UE) with multiple receiving (RX) beams, stores the measured TX-RX pair in a measurement matrix, and calculates a consolidation measurement for each cell based on a consolidation rule. In one embodiment, the consolidation rule indicates generating a RX consolidated vector by consolidating all RX beams with the same TX beam ID, and subsequently, generating the consolidation measurement for the cell based on the RX consolidated vector. In another embodiment, the measurement matrix is layer-3 filtered and consolidated. In yet another embodiment, the UE sends a measurement report, either contains the consolidated measurement or the measurement vector, to the NR network based on the consolidation measurement. In one embodiment, the network performs consolidation on the received measurement vector.
