Abstract: A communication device includes a level one (L1) processing element configured to measure downlink (DL) reference signals from multiple beams received via a transceiver to generate L1 data describing the multiple beams. The device also includes a level two (L2) processing element configured to consolidate, select, or filter the multiple beams responsive to the L1 data to produce L2 data corresponding to one or more of the multiple beams in a first cell that are consistent with preconfigured parameters. Furthermore, the device includes a level three (L3) processing element coupled to the L1 and L2 processing elements and configured to generate L3 data corresponding to one or more of the multiple beams in each of the first cell and a second cell. The device also includes a report generator coupled to the L1, L2 and L3 processing elements and configured to generate a report for a mobility event.

Abstract: A method for operating a user equipment (UE) adapted to perform beaconing includes beamforming a beacon signal in accordance with at least one transmit beam of a set of transmit beams, thereby producing at least one beamformed beacon signal, transmitting the at least one beamformed beacon signal on a first uplink channel, repeating the beamforming and the transmitting for remaining transmit beams of the set of transmit beams, and receiving downlink reference signals from a transmit-receive point using receive beamforming and beam adjustment.
