摘要： 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.

摘要： Systems, methods, and instrumentalities are described for handling positioning reference signals in a wireless communication system. The positioning reference signals may be assigned priorities that may be used to facilitate various operations of a wireless transmit/receive unit (WTRU) such as positioning related services, collision avoidance, measurement and reporting, etc. The WTRU may be configured with multiple muting patterns associated with the positioning reference signals and may switch between different muting patterns based on the priorities of the positioning reference signals and/or other downlink (DL) or uplink (UL) transmissions that may overlap or collide with the positioning reference signals.

摘要： Systems, methods, and instrumentalities are described herein that may be used to determine a destination for sidelink transmission based on the priority of the transmission and/or other parameters associated with the transmission. In examples, a destination may be selected if one or more logical channels associated with the destination have a bucket size parameter exceeding a certain threshold and the one or more logical channels have a highest priority. Various other techniques are also described herein that relate to the configuration and/or report of QoS information, selection of sidelink resources, use of a minimum communication range, etc.

摘要： A method and apparatus for selecting a resource for transmission may be performed by a WTRU. The method may comprise determining a priority of a data packet and determining a CBR of a resource pool. The WTRU may set a backoff counter to an initial backoff value, in accordance with at least one of the priority of the packet or the CBR. A CCA may be performed in a plurality of resource slots to determine whether the resource slots are available. The backoff counter may be decreased by the number of available resources in each slot. When the backoff counter reaches a threshold value, which may be set at 0, the resource for transmission may be randomly selected. The WTRU may then transmit data to another WTRU on the randomly selected resource.

摘要： Systems, methods, and instrumentalities are described herein for sidelink discovery, for example, associated with relays, e.g., NR relays. Discovery data may be transmitted, for example, to initialize communication between devices. Discovery data may be transmitted alone or multiplexed with other data (e.g., sidelink data). Discovery data with a high priority may be transmitted alone. Discovery data with a low priority may be multiplexed with other data (e.g., other data received within a duration of time). Discovery data may be multiplexed with other data that share the same destination identity. Resource allocation may be performed, for example, based on whether the discovery data is transmitted alone or multiplexed with other data.

摘要： A WTRU may be configured to perform logical channel prioritization. A WTRU may receive an indication (e.g., a mapping) that indicates an association between a first HARQ process ID and a first HARQ processing type and between a second HARQ process ID and a second HARQ processing type. The WTRU may receive an indication (e.g., a mapping) that indicates an association between a first logical channel and the first HARQ processing type and between a second logical channel and the second HARQ processing type. The WTRU may receive an a HARQ process ID indication. The WTRU may determine a HARQ processing type associated with the HARQ process ID. The WTRU may determine a logical channel available for a transmission. The logical channel available to be used may be determined based on the HARQ processing type associated with the HARQ process ID. The WTRU may send the transmission.

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： Methods and apparatuses are described herein for sidelink communication in a wireless transmit/receive unit (WTRU). For example, a first WTRU configured with first and second resource pools may perform at least one congestion measurement of the second resource pool. The first resource pool may be configured for use by the first WTRU for transmission of the first data. The second resource pool may be configured for use by a second WTRU for transmission of the second data associated with a higher priority than the first data. If the at least one congestion measurement of the second resource pool is below a predetermined threshold, the first WTRU may transmit the first data using the first resource pool. If the at least one congestion measurement of the second resource pool is above a predetermined threshold, the first US may not transmit the first data using the first resource pool.
