  • Patent number: 11382139
    Abstract: A User Equipment (UE) measures the signal quality of a dedicated downlink reference signal transmitted by a Base Station (BS) to the UE. If the signal quality is below a threshold, the UE initiates a measurement procedure to determine a target handover BS. The UE sequentially transmits an uplink reference signal on each of UE's beams. The BSs estimate the Angle of Arrival (AoA) of any received uplink reference signal, form a dedicated downlink beam pointed toward the AoA and transmit an acknowledgment to the UE on the corresponding beam. The UE estimates the signal quality of the received acknowledgements on the different UE beams, and transmits a handover message on the UE beam on which the acknowledgement with the highest signal quality is received The acknowledgement comprises a preamble, spread using a pseudo-noise sequence specific to each BS.
