US Patent 11792802 Uplink shared channel feedback piggybacking

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an uplink grant that indicates scheduling information for an uplink shared channel transmission by the UE. The UE may also receive a downlink grant scheduling feedback information to be piggybacked on the uplink shared channel transmission, and may determine whether the downlink grant has been received after the uplink grant. The UE may then select from a set of resources indicated in the uplink grant, or determine that a feedback piggybacking condition has been met based on the downlink grant. The UE may perform the uplink shared channel transmission to the base station, in some cases including the feedback information.
