Abstract: Embodiments of this application provide a communication method and apparatus, and a readable storage medium. The method includes: A first device sends information about a first priority and a second priority to a second device. The first priority is used to assist the second device in selecting a resource for sidelink transmission, the information about the first priority is carried in SCI and/or a MAC CE, and the second priority is a physical layer priority of the first device. In the method, the first device sends the information about the first priority and the second priority to the second device. The information about the first priority is used to assist the second device in selecting the resource for sidelink transmission. Therefore, the second device may further select, based on the information about the first priority, the resource for sidelink transmission, to implement resource selection of the second device.

Abstract: A communication method and a sidelink device. The method includes: determining, by a first sidelink device, first indication information and first sidelink resource information; and sending, by the first sidelink device, the first indication information and the first sidelink resource information to a second sidelink device, where the first indication information indicates that the first sidelink resource information includes auxiliary information, and the auxiliary information is used to assist the second sidelink device in resource selection. After receiving the first indication information and the auxiliary information, the second sidelink device can learn about a surrounding related resource status, such as channel measurement information of a resource pool, and a resource occupation status of another communication device with which the second sidelink device cannot directly communicate. The second sidelink device may perform resource selection based on the auxiliary information.

Abstract: This application provides an information transmission method and apparatus, to resolve a problem of a conflict between resources used by a terminal device to send/receive information in different radio access systems, ensure successful transmission of information with a high priority, and improve communication quality. A terminal device determines information with a higher priority in first information associated with a first radio access system and second information associated with a second radio access system. Time domain resources associated with the first information and the second information are completely or partially the same. The first information is data information and the second information is synchronization information, or the first information is synchronization information and the second information is synchronization information. The terminal device sends or receives the information with the higher priority.

Abstract: A transmit end obtains a frequency hopping parameter and resource allocation information of a to-be-transmitted message, where the frequency hopping parameter includes at least one of bandwidth part indication information, beam indication information, reference signal configuration information, subcarrier spacing indication information, transmission waveform indication information, slot type indication information, channel type indication information, or transmission carrier indication information. The transmit end determines, based on the resource allocation information and the frequency hopping parameter, a physical resource used to send the to-be-transmitted message, where the physical resource includes information about a frequency domain resource on which the to-be-transmitted message is mapped in at least one time unit. The transmit end sends the to-be-transmitted message by using the physical resource.
