Abstract
Receiver assisted channel access may be used during a channel occupancy time (COT). A wireless transmit/receive unit (WTRU) that is a member of a first group may receive a preamble in a first time slot set, and determine a group associated with the first time slot. On a condition that the group associated with the first time slot set is the first group, the WTRU may monitor the channel for a request-to-send (RTS) signal in the first slot set. On a condition that the RTS signal is received, the WTRU may perform listen-before-talk (LBT) on the channel. On a condition that the LBT is successful, the WTRU may transmit a clear-to-send (CTS) on the channel and access the channel in the first time slot. On a condition that the LBT is unsuccessful, the WTRU may not access the channel in the first time slot set.
