Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) or multiple UEs may transmit a grant-free uplink transmission to a base station. The base station may monitor resources for the grant-free uplink transmission (e.g., from one or more UEs) and the base station may generate a group feedback message corresponding to whether the base station successfully received the uplink transmission(s). The group feedback message may contain feedback for multiple uplink transmissions from one or multiple UEs. The group feedback message may be transmitted to a UE over a downlink shared channel or a downlink control channel and the UE may receive the group feedback message and may determine whether to retransmit the uplink transmission based on the group feedback message.
