Abstract:
A method is provided including transmitting a reference signal on a downlink beam to a UE; receiving from the UE a reference signal sequence; determining from the received reference signal sequence at least a preferred uplink beam to pair with the downlink beam; sending downlink signaling to the UE on at least the downlink beam; and receiving uplink signaling from the UE on at least the preferred uplink beam. A further method is provided including receiving a reference signal from a network on a downlink beam; selecting at least one preferred uplink beam to match the downlink beam; selecting a reference signal sequence that corresponds to the selected at least one preferred uplink beam; transmitting the selected reference signal sequence to the network; receiving downlink signaling from the network on at least the downlink beam; and transmitting uplink signaling to the network on the at least one preferred uplink beam.
