Embodiments of this application relate to the field of communications technologies. The method includes: A terminal triggers a resource scheduling request when the terminal meets a first trigger condition, where the resource scheduling request is used to request an access network device to allocate an uplink resource or a sidelink resource to the terminal; and the first trigger condition includes: A working mode of the terminal or a working mode of a sidelink service of the terminal is switched from a first mode to a second mode, where the first mode is different from the second mode, and the first mode and the second mode each are one of the following modes: a scheduling mode and a scheduling and autonomous joint mode.

A first device in a communication network receives from at least one second device in the communication network, a first request for acquiring a token, the token being permission for communicating with a third device. Based on the first request, a device from the at least one second device and the first device as a communication device is selected for providing a communication service to the third device in the communication network; and the token is transmitted to the communication device. The communication device receives the token for communicating with the third device. Other devices receive key information associated with communication of the third device from the first device, and monitor data associated with the communication of the third device.

A terminal device includes: a pedestrian-to-vehicle communication device configured to communicate with an in-vehicle terminal by using a first communication method, in which direct communication is performed as pedestrian-to-vehicle communication; a wireless LAN communication device configured to communicate with the in-vehicle terminal by using a second communication method, in which indirect communication is performed via a roadside device disposed on or near a road; and a controller configured to determine whether or not the terminal device is in a risky state based on state information indicating a state of the terminal device, and select either one of the first communication method, in which direct communication is used and the second communication method, in which indirect communication is used, based on a result of the determination.

Proposed is a method for a first device to perform wireless communication. The method may comprise the steps of: receiving information related to the allocation of a first resource from a base station; transmitting sidelink information to a second device through the first resource on the basis of the information related to the allocation of the first resource; and transmitting the sidelink information to the second device through a second resource on the basis of a preset condition.

A method and apparatus for conditional supplementary link activation and transmission in a wireless communication system is provided. A wireless device configures a primary transmission link and at least one supplementary transmission link. The primary transmission link is activated. The wireless device configures a first condition and a second condition. The wireless device determines that the first condition is met upon which the at least one supplementary transmission link is activated. The wireless device performs transmission by using at least one of activated transmission links based on whether the second condition is met.

Channel occupancy time (COT) aware sensing and resource selection for new radio-unlicensed (NR-U) sidelink operations is disclosed. A first sidelink user equipment (UE) determines a sensing window or resource selection window (RSW) based on a projected listen-before-talk (LBT) completion time. The UE may sense for a subset of sideline resources within the RSW and COT-SI from a neighboring sidelink UE including identification of a COT initiated by the neighboring UE and one or more parameters associated with the COT. The UE may identify in-COT resources of located within the COT and out-COT resources located outside of the COT and then randomly select a set of transmission resources from the in-COT and out-COT resources. The UE may then transmit to a second UE using the set of transmission resources.

A first device in a communication network receives from at least one second device in the communication network, a first request for acquiring a token, the token being permission for communicating with a third device. Based on the first request, a device from the at least one second device and the first device as a communication device is selected for providing a communication service to the third device in the communication network; and the token is transmitted to the communication device. The communication device receives the token for communicating with the third device. Other devices receive key information associated with communication of the third device from the first device, and monitor data associated with the communication of the third device.

The present disclosure provides a communication method. The method includes: sending, by a first terminal device, a solicitation message, where the solicitation message includes a measurement threshold; and receiving, by the first terminal device, a response message sent by at least one second terminal device, where a signal measurement result of a link between the second terminal device and the first terminal device is greater than or equal to the measurement threshold.

A method for performing wireless communication by a first device is proposed. The method may comprise the steps of: transmitting first sidelink control information (SCI) related to initial transmission, to a second device through a first physical sidelink control channel (PSCCH), wherein the first SCI related to the initial transmission includes scheduling information of second SCI related to the initial transmission, which is transmitted through a first physical sidelink shared channel (PSSCH) related to the first PSCCH; transmitting, to the second device, a medium access control protocol data unit (MAC PDU) and the second SCI related to the initial transmission through the first PSSCH, wherein the second SCI related to the initial transmission includes location information of the first device, which is related to the initial transmission; transmitting first SCI related to retransmission, to the second device through a second PSCCH, wherein the first SCI related to the retransmission includes scheduling information of second SCI related to the retransmission, which is transmitted through a second PSSCH related to the second PSCCH; and transmitting, to the second device, the MAC PDU and the second SCI related to the retransmission through the second PSSCH, wherein the second SCI related to the retransmission includes the location information of the first device, which is related to the initial transmission.

A communication device can have a peer-to-peer communication application installed on it. The device can be configured to detect at least one other communication device including the peer-to-peer communication application, and may be configured to set up a connection with the detected communication device. The device can be configured to, in response to a request to set up peer-to-peer communication sent to the first device on a predetermined port and via a predetermined protocol by a second detected device exchange with the second device information required for setting up peer-to-peer communication with the second device, and to set up the peer-to-peer communication. The peer-to-peer communication application can be configured to send, on the predetermined port and via the predetermined protocol a request to set up peer-to-peer communication to a third detected communication device.
