Acknowledgement mechanisms for uplink low latency communications
Methods, systems, and devices for wireless communications are described for providing acknowledgements of grant-free uplink transmissions, which may in some cases be used for low latency communications. Approaches described herein include the use of per-user equipment (UE) acknowledgement resources assigned to UEs configured for grant-free uplink transmissions as well as the use of per-group acknowledgement resources assigned to groups of UEs configured for grant-free uplink transmissions. Dynamic puncturing of data in a shared downlink data channel may be used in the context of per-UE acknowledgement resource assignment. Corresponding grants of uplink transmission resources may be used in the context of per-group acknowledgement resources assignments.
