Uplink multi-beam operation

Abstract:

Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive, a downlink control signal indicating that an uplink control signal is to be transmitted using two or more transmission beams during different transmission time intervals (TTIs). The UE may identify the two or more transmission beams based at least in part on the downlink control signal, and may transmit a plurality of repetitions of an uplink signal on the two or more transmissions beams. Each repetition may be transmitted on a different TTI using a different one of the two or more transmission beams based at least in part on the downlink control signal.
