Abstract
A wireless transmit/receive unit (WTRU) may receive a downlink communication from a network over a first interface transmitted to one or more WTRUs in a group of WTRUs. The WTRU may determine an access class of the WTRU based on a packet loss percentage of the downlink communication. The access class may be associated with a contention window for accessing a second interface. The WTRU may transmit packet loss information to the one or more WTRUs over the second interface in the contention window. The WTRU may receive packet loss feedback from the one or more WTRUs over the second interface. The WTRU may determine that the access class of the WTRU is a highest class of the one or more WTRUs. The WTRU may transmit a single groupcast negative acknowledgement (gNACK) to the network on behalf of the one or more WTRUs over the first interface.
