Abstract:
Methods, systems, and devices for wireless communications are described. Techniques for multiple transmission reception points (TRPs) in a cluster may coordinate scheduling and communications with a user equipment (UE). Different TRPs may allocate uplink resources for one or more UEs within a coordinated cluster to transmit feedback information. A first TRP may provide a first set of resources that one or more associated UEs may use to transmit acknowledgment (ACK) feedback to indicate successful receipt of a downlink transmission of the first TRP, and one or more other TRPs of the coordinated cluster may provide a second set of resources that the one or more UEs may use to transmit negative acknowledgment (NACK) feedback to indicate that a downlink transmission of the first TRP was lost. The second set of resources may include non-orthogonal multiple access (NOMA) resources.
