Abstract: Wireless communications are described. A user equipment (UE) may receive a configuration message identifying a set of resources available for a plurality of UEs for transmission of feedback indications of multi-cast (or broadcast) transmission to the plurality of UEs, the set of resources comprising a plurality of subsets of resources, each subset of resources being associated with a corresponding channel metric for each UE of the plurality of UEs receiving the multi-cast transmission. The UE may determine that a feedback indication is to be provided in response to the multi-cast transmission. The UE may select, based at least in part on a channel metric of the UE, a first subset of the plurality of subsets of resources to use for transmitting a feedback message including the feedback indication. The UE may transmit the feedback message for the multi-cast transmission using resources within the selected first subset of resources.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may use enhanced techniques for determining whether a transmission is scheduled to include new data when a mode for reporting acknowledgment feedback is disabled for one or more hybrid automatic repeat request (HARQ) processes used by the receiving device. An enhanced technique may include increasing a quantity of bits used to convey an indication of whether a scheduled data transmission includes new data. An enhanced technique may include monitoring a duration between transmissions scheduled by different control messages based on a timing parameter that indicates a maximum time between transmissions of a data set and corresponding transmission including the data set.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may receive a feedback configuration for providing feedback for downlink communications from a base station. Based on the feedback configuration, the UE may determine whether one or more feedback processes has a multicast-only configuration for multicast data communications, or a multicast-or-unicast configuration for either multicast data communications or unicast data communications. The UE may decode one or more transmissions associated with the one or more feedback processes based on the multicast-only or multicast-or-unicast configuration, and may determine a feedback codebook based on the multicast-only or multicast-or-unicast configuration of the one or more feedback processes. The UE may monitor for retransmissions of one or more multicast data communications based on the feedback process configuration.
