Abstract: An information transmission method, performed by a first terminal, includes: monitoring a channel in a first type of channel access mode or a second type of channel access mode, where the first terminal is configured to perform a PSFCH transmission in an unlicensed frequency band. An information transmission method, performed by a network device, includes: configuring first indication information, or a first channel access priority, or first indication information and a first channel access priority for a first terminal, where the first indication information instructs the first terminal to monitor a channel in a Type2A channel access mode, a Type2B channel access mode, or a Type2C channel access mode, and the first channel access priority is a channel access priority used by the first terminal to monitor the channel in a first type of channel access mode.

Abstract: A method and a device for sending a coordination request. A first terminal device determines a trigger condition of the coordination request. The first terminal device is triggered to send the coordination request to a second terminal device according to the trigger condition of the coordination request. The second terminal device receives the coordination request sent by the first terminal device.

Abstract: Physical sidelink feedback methods and apparatuses, and storage media are provided. The physical sidelink feedback method includes: receiving one or more code block groups CBGs sent by a second user equipment to a first user equipment, and sending HARQ feedback for the one or more CBGs to the second user equipment.

Abstract: The present disclosure relates to a resource selection method, a resource selection device and a storage medium. The resource selection method comprises: determining a first moment and a first time interval; determining a second moment on the basis of the first moment and the first time interval, the second moment being at the first time interval from the first moment; and taking the second moment as a starting moment of a first device for resource selection, or a starting moment of a resource selection window of the first device.

Abstract: The present disclosure provides a communication method and a communication device. In the communication method, in response to determining that a reserved resource for transmitting data is subject to a consecutive resource collision in a plurality of transmission periods, data transmission with the reserved resource is stopped.

Abstract: A method and a device for communication based on a physical sidelink shared channel are disclosed. The method includes: determining the physical sidelink shared channel, in which the physical sidelink shared channel includes more than one transmission start position for a sidelink signal; and transmitting a sidelink signal on an unlicensed frequency band based on the more than one transmission start position.
