Abstract:
This disclosure provides methods, devices, and systems for resource selection supporting user equipment (UE)-shared multicast feedback. In some systems, a UE and a base station may support multicast communications. The base station may configure a set of physical uplink control channel (PUCCH) resources that the UE may use for multicast feedback messages. The base station may transmit an indication of the set of PUCCH resources to the UE, and the UE may determine to use a PUCCH resource of the set of PUCCH resources based on one or more indications from the base station. The UE may fail to receive a multicast message from the base station and may transmit a UE-shared negative acknowledgment (NACK) feedback message. The base station may re-transmit the multicast message according to a set of transmission parameters that is based on which PUCCH resource was used by one or more UEs for multicast NACK feedback.
