    摘要: 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.

    摘要: A wireless transmit/receive unit (WTRU) may perform a listen before talk (LBT) procedure associated with a sidelink (SL) bandwidth. The SL bandwidth may include a resource block (RB) set. The WTRU may determine a CSLF associated with the RB set of the SL bandwidth based on the LBT procedure. The WTRU may determine a resource for reporting the CSLF, for example, based on a priority rule. The priority rule may indicate that a licensed resource has a higher priority than an unlicensed resource. The priority rule may indicate that, if a consistent LBT failure is not detected on an unlicensed uplink (UL) resource, the unlicensed UL resource has a higher priority than an unlicensed SL resource. The WTRU may send a medium access control (MAC) control element (CE) using the determined resource. In examples, the MAC CE may indicate the RB set.

    摘要: A method performed by a WTRU may comprise receiving first periodic uplink transmission information and second periodic uplink transmission information which are different. The method may further comprise receiving configuration information indicating that data of a first logical channel is allowable for transmission in accordance with the first periodic uplink transmission information and that data of a second logical channel is allowable for transmission in accordance with the second periodic uplink transmission information. Data of the first logical channel may be transmitted in accordance with the first periodic uplink transmission information and data of the second logical channel may be transmitted in accordance with the second periodic uplink transmission information.
