    摘要： A system and a method are disclosed for multi-slot resource reservations in new radio (NR) sidelink (SL) using the unlicensed spectrum. Embodiments include determining, by an NR user equipment (UE), a multi-slot reservation configuration, wherein the multi-slot reservation configuration comprises a plurality of reservation slots corresponding to a time domain and frequency domain; performing, by the NR UE, a listen-before-talk (LBT) operation; and in response to LBT operation, indicating, by the NR UE, a selection of a plurality of multi-slot resources in the time domain and the frequency domain on which to transmit one or more signals, the plurality of multi-slot resources corresponding to the plurality of reservation slots of the multi-slot reservation configuration. Embodiments further include updates to Mode 2 signaling including the plurality of multi-slot resources is further based on an evaluation of a high-layer parameter, and/or selecting a single-candidate resource slot, based on consecutive subsequent slots.

    摘要： Provided are a method for performing wireless communication by a first device, and an apparatus for supporting same. The method may comprise: determining a channel occupancy time, COT, based on sensing for channel access; transmitting, to a second device, information related to the COT; transmitting, within the COT, first sidelink control information, SCI, for scheduling of a physical sidelink shared channel, PSSCH, and second SCI through a physical sidelink control channel, PSCCH; transmitting, within the COT, the second SCI and a medium access control, MAC, protocol data unit, PDU, through the PSSCH; determining to terminate the COT; and transmitting, to the second device, information related to COT termination based on the determination.

    摘要： The present disclosure provides methods and apparatuses for performing sidelink-based vehicle to everything (V2X) communication. In some embodiments, an operation method includes receiving, by the second device from the first device during a first symbol period, a physical sidelink control channel (PSCCH) and a first physical sidelink shared channel (PSSCH), based on a first transmission configuration indication (TCI) state assigned to the PSCCH. The first symbol period includes first symbols on which the PSCCH and the first PSSCH are received. The operation method further includes receiving, by the second device from the first device during a second symbol period that follows the first symbol period, a second PSSCH, based on a second TCI state. The second symbol period includes second symbols on which the second PSSCH is received.

    摘要： A method may include transmitting a request groupcast message to a plurality of user equipment for their respective preferred or non-preferred resources. The method may also include receiving an information message including the preferred or the non-preferred resources from each user equipment of the plurality of user equipment in response to the request groupcast message. The method may further include identifying, based on the information message, at least one resource from the preferred or non-preferred resources for selection by the plurality of user equipment. In addition, the method may include notifying, via information tethering, to each user equipment of the plurality of user equipment, the identified at least one resource that corresponds to the apparatus and to each user equipment of the plurality of user equipment.
