Claim of US Patent No. 11,032,842

1. A method for wireless communication at a base station, comprising:establishing communications with a user equipment (UE) using a first pair of beamformed transmission beams, the first pair of beamformed transmission beams including a first downlink beam for transmissions from the base station to the UE and a first receive beam for receiving the first downlink beam at the UE;
transmitting a first transmission associated with a first scheduling offset comprising a first repetition of a plurality of repetitions of control information to the UE, wherein the first repetition of the plurality of repetitions is transmitted in advance of a scheduling threshold;
transmitting a second transmission associated with a second scheduling offset comprising a second repetition of the plurality of repetitions of the control information to the UE, the first repetition and the second repetition each including a same set of resources and providing an indication of a second beam pair for a scheduled transmission with the UE;
determining the scheduling threshold for the UE that corresponds to a time in advance of a start time of the set of resources for the UE to change from the first receive beam to a second beam for the scheduled transmission;
identifying a predetermined beam pair that is used for the scheduled transmission based on control information transmitted to the UE after the scheduling threshold; and
setting the indication of the second beam pair based at least in part on whether one or more of the plurality of repetitions is transmitted after the scheduling threshold.
