Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a first transmission on a first set of beams is unsuccessful and determine a second transmission on a second set of beams is successful. The UE may identify a beam from the second set of beams based on the determination that the second transmission on the second set of beams is successful. The UE may transmit, to a base station, an indication of the identified beam from the second set of beams and communicate with the base station via the identified beam from the second set of beams.
Claims27
A method for wireless communications at a user equipment (UE), comprising:
- determining a first data transmission on a first set of beams during an initial transmission period of a first data exchange cycle is unsuccessful, wherein the first data exchange cycle is scheduled between the UE and the network device;
- determining a second data transmission on a second set of beams during a retransmission period of the first data exchange cycle is successful;
- identifying a beam from the second set of beams based at least in part on the determination that the second data transmission on the second set of beams is successful;
- transmitting, to the network device during the retransmission period of the first data exchange cycle, at least one of a feedback message comprising a first indication that the second data transmission was received successfully and a second indication of the identified beam from the second set of beams or a retransmission of the first data transmission comprising the second indication of the identified beam from the second set of beams;
- and
- communicating with the network device via the identified beam from the second set of beams during a second data exchange cycle scheduled between the UE and the network device, wherein the second data exchange cycle is subsequent to the first data exchange cycle.
