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.

Abstract: A 5G wireless communication system to transmit a beam ID or part of a beam ID by joint design of a secondary synchronization sequence (SSS) and Physical Broadcast Channel (PBCH). In 5G during the initial access procedure a terminal will try to obtain fundamental system information/identifiers which are required for future signal transmission/reception activities. Due to the extensive usage of beamforming techniques in 5G, besides identifying a cell ID and obtaining time/frequency synchronization, the terminal may identify a beam ID during the initial access procedure. Therefore, a beam ID is transmitted as part of synchronization signals (SS) broadcast by a gNB, more particularly as part of SSS or as part of PBCH. The synchronization signals may be transmitted as a set of SS blocks, each having an index, which may be a time index, for facilitating identification.

Abstract: In a beamforming system, each User Equipment (UE) transmits an uplink probe. Each Base Station (BS) carries out a spatial search of the uplink probes, estimates an Angle of Arrival (AoA) of the uplink probe received from each UE, and estimates the uplink channel frequency response on an uplink dedicated beam formed toward the UE's AoA. The BS transmits a reference signal to each UE on a downlink dedicated beam formed toward the UE's AoA, from which the UE estimates the downlink frequency response. The UE forms channel impulse response matrices for the uplink and the downlink, using the estimated uplink and downlink channel frequency responses. The BS uses the channel impulse response matrices to form downlink and uplink dedicated beams that put boresight of the beams toward the AoA of one UE and put nulls toward the AoAs of the other UEs.
