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.

Abstract: A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.

Abstract: A radio network sends downlink signaling to a user equipment (UE) that triggers an enhanced uplink beam selection protocol, based on quality of the UE's uplink signaling the network receives according to a basic uplink beam selection protocol. In response the UE transmits pre-defined signaling such as uplink beam references signals (U-BRS) with uplink beams according to the downlink signaling. The network measures and selects one or more of those uplink beams for the UE to use for sending uplink data, and notifies this selection to the UE. In various embodiments the basic uplink beam selection protocol is based on uplink-downlink reciprocity, the downlink triggering signaling is dynamic and further selects a subset of uplink beams, and multiple UEs can be triggered in common signaling where blind decoding by the UEs is enabled via a scrambling ID for this enhanced uplink beam selection protocol purpose.
