1. A method for wireless communications at a network device, comprising:
transmitting, to a first user equipment (UE) of a plurality of UEs in communication with the network device, a radio resource control (RRC) configuration message indicating a first location within a bitmap for feedback for the first UE, the feedback associated with grant-free uplink transmissions for the first UE;
monitoring a set of time-frequency resources for one or more grant-free uplink transmissions from the plurality of UEs in communication with the network device;
generating a group feedback message for the plurality of UEs, wherein the group feedback message comprises an indication of whether a respective grant-free uplink transmission was received from each UE of the plurality of UEs based at least in part on the monitoring, wherein generating the group feedback message comprises generating the bitmap that indicates feedback for each UE of the plurality of UEs, wherein the bitmap is a first type of feedback bitmap of multiple types of feedback bitmaps, and wherein the first location within the bitmap includes feedback for the first UE for the respective grant-free uplink transmission in accordance with the RRC configuration message; and
transmitting, to the plurality of UEs, the group feedback message comprising the feedback bitmap indicating the feedback for each UE of the plurality of UEs.
