Abstract: A user equipment (UE) is provided that includes a memory and a processor. The processor is configured to determine whether to send assistance information. In response to determining to send the assistance information, the processor is also configured to transmit the assistance information either via sidelink control information (SCI) or via a medium access control (MAC) control element (CE) having one or more resource selection assistance information elements.

Abstract: A system and a method are disclosed for sidelink operations in unlicensed spectrum. In some embodiments, the method includes: receiving, by a first User Equipment (UE), a physical sidelink shared channel (PSSCH) transmission; refraining from sending an acknowledgment/negative acknowledgment (ACK/NACK) transmission, by the first UE, during a first Physical Sidelink Feedback Channel (PSFCH) occasion, wherein the refraining from sending occurs in response to an unsuccessful Listen Before Talk (LBT) attempt performed for the first PSFCH occasion; and sending an ACK/NACK transmission for the PSSCH transmission, during a second PSFCH occasion following the first PSFCH occasion.

Abstract: A system and a method are disclosed for beam pairing. In some embodiments, the method includes: accessing, by a first User Equipment (UE), configuration data indicating a slot structure including a plurality of resources for transmissions in different directions; and based on the configuration data, transmitting, by the first UE, in a single slot, a first transmission portion using a first resource of the plurality of resources with a first beam direction and a second transmission portion using a second resource of the plurality of resources with a second beam direction, different from the first beam direction.

Abstract: A system and a method are disclosed for positioning. In some embodiments, the method includes transmitting, by a first User Equipment (UE): a first Positioning Reference Signal (PRS) transmission, and, immediately preceding the first PRS transmission, a duplicate of a symbol of the first PRS transmission, the duplicate and the first PRS transmission being in a same slot as: a second PRS transmission, multiplexed in time with the first PRS transmission, transmitted by a second UE, and, immediately preceding the second PRS transmission, a duplicate, of a symbol of the second PRS transmission, transmitted by the second UE.

Abstract: Methods and apparatuses are provided in which a user equipment (UE) determines a resource pool for reception of a sidelink (SL)-positioning reference signal (PRS). The UE receives a slot and determines whether the slot includes resources in the resource pool for the SL-PRS. The UE decodes SL control information (SCI) of the slot using a first format for the SL-PRS, in case that the slot includes the resources in the resource pool.

Abstract: An apparatus and a method are disclosed for SL communication over an unlicensed band by utilizing a frequency interlaced design. A method performed by a UT includes determining whether the UE is operating in a localized mode or an interlaced mode for SL communication, and in response to determining that the LE is operating in the interlaced mode, decoding first stage SCI of a PSCCH based on an interlaced mapping scheme, decoding second stage SCI of a PSSCH based on the decoded first stage SCI, and decoding the PSSCH based on the decoded first and second stage SCI.

Abstract: A device may perform a transmission that may occupy at least a portion of a first slot and perform a listen-before-talk (LBT) sensing operation, wherein the LBT sensing operation may occupy at least a portion of an LBT gap, and at least a portion of the LBT gap may occupy at least a portion of a second slot. A device may perform a transmission that may occupy at least a portion of a first slot, transmit an indication of a resource for an LBT sensing operation, perform an LBT sensing operation for the transmission that may occupy at least a portion of a second slot, and transmit, based on the LBT sensing operation, a reservation signal that may occupy at least a portion of the second slot. A device select a resource for a transmission using a sidelink channel, and select a resource for an LBT sensing operation.

Abstract: A method and apparatus are provided for pre-emption, congestion control, and Tx/Rx alignment for use by a partial sensing UE. A method includes measuring resources within a first window; determining a number of the measured resources having an RSSI greater than a first threshold; determining a CBR based on the measured number of resources; and determining a CR limit based on the determined CBR and transmission priority. Determining the CBR based on the measured number of resources includes comparing a total number of measured resources within the first window to a second threshold; in response to the total number of measured resources being less than the second threshold, determining the CBR as a pre-configured CBR; and in response to the total number of measured resources being greater than or equal to the second threshold, determining the CBR based on a ratio of the number of the measured resources having the RSSI greater than the first threshold to the total number of measured resources within the first window.
