    Abstract: A transmitting wireless transmit/receive unit (Tx WTRU) may receive configuration information that indicates one or more parameters. The one or more parameters may be associated with resource selection. The Tx WTRU may determine a first resource selection window and a second resource selection window. The first resource selection window may be associated with an active time of a receiving wireless transmit/receive unit (Rx WTRU). The second resource selection window may be associated with an inactive time of the Rx WTRU. The Tx WTRU may determine a first number of candidate resources associated with the first resource selection window. The Tx WTRU may determine a first number of candidate resources associated with the second resource selection window. In examples, the Tx WTRU may increase the first number of candidate resources associated with the first resource selection window to a second number of candidate resources associated with the first resource selection window.

    Abstract: Systems, methods, and instrumentalities are described herein that may be associated with new radio (NR) vehicular communication (V2X) sidelink power saving for unicast and groupcast. A first wireless transmit/receive unit (WTRU) may receive a message. The message may indicate a set of configuration groups and/or one or more suitability selection parameters. The WTRU may receive, from a second WTRU, a first indication. The first indication may indicate that the second WTRU is associated with a first configuration group and a first priority group. The first WTRU may receive, from a third WTRU, a second indication. The second indication may indicate that the third WTRU is associated with a second configuration group and a second priority value. The first WTRU may select a configuration group from the set of configuration groups based on the first indication and the second indication.

    Abstract: Systems, methods, and instrumentalities are described herein for sidelink (SL) collision detection and indication (e.g., in new radio (NR) vehicular communications (V2X)). A wireless transmit/receive unit (WTRU) may send resource reservations (e.g., in sidelink control information (SCI)). A receiving (RX) WTRU may receive SCI from (e.g., multiple) transmitting (TX) WTRUs, where the TX WTRUs are reserving resources for transmission. The TX WTRUs may be unaware of the other TX WTRUs (e.g., unaware of the resources being reserved by other TX WTRUs). Resources may be in conflict, for example, if the reserved resources overlap (e.g., partially or completely). Collision may occur, for example, if multiple TX WTRUs reserve the resources in conflict for transmission and/or if the TX WTRUs reserving the resources in conflict for transmission do not reselect a non-conflicting resource.

    Abstract: Methods, devices, and systems for congestion control in a wireless communications system. Some embodiments including receiving a plurality of zone configurations, receiving, for each of the plurality of zone configurations, a channel busy ration (CBR) threshold and a mapping of zone identities (IDs) to resource pools; and measuring a CBR of a resource pool with which the WTRU is currently configured. If the measured CBR meets a CBR threshold of a first zone configuration of the plurality, the WTRU is configured with the first zone configuration, with a zone ID based on the first zone configuration and apposition of the WTRU, and with a resource pool base on the mapping and configured zone ID.
