Abstract: A message relay arrangement is described. A first terminal sends a first message to a second terminal, where the first message that instructs the second terminal to determine a type of the second terminal based on the first message. Based on the terminal type, the second terminal operating as the first-type terminal sends first measurement information; or operating as the second-type terminal receives first measurement information sent by a first-type terminal, determines quality of a first link between the first-type terminal and the second-type terminal, and sends the quality of the first link to the first terminal. The first terminal receives the quality of the first link sent by the second-type terminal. The first terminal determines a mapping relationship between the first-type terminal and the second-type terminal based on the quality of the first link. The first terminal sends the mapping relationship to terminals corresponding to the mapping relationship.

Abstract: Example data transmission methods and apparatus are described. One example method includes obtaining first configuration information by a terminal device. The first configuration information includes at least one first bearer identifier and path configuration information corresponding to the first bearer identifier, and the path configuration information corresponding to the first bearer identifier includes at least one of a sidelink transmission path or a network device forwarding transmission path. The terminal device obtains first service data and a second bearer identifier corresponding to the first service data, and selects a transmission path for the first service data based on the first bearer identifier, the second bearer identifier, and the path configuration information. The terminal device transmits the first service data on the transmission path.

Abstract: Embodiments of the present application provide a resource processing method, an apparatus, and a terminal. The method includes: receiving, by a first terminal, a first message simultaneously sent by each of at least one second terminal, where the first message is carried on N resources and used to indicate location information of resources on which to-be-sent data is located, and N is a positive integer greater than or equal to 2; and determining, by the first terminal based on the location information of the resources on which the to-be-sent data is located, resources used by the first terminal to send data. Because the first message is carried on the N resources, a probability of collision of the resources used by the second terminal to send the first message is very low.

Abstract: A data transmission in a wireless network is described. The data transmission includes: determining, by a terminal device, a first configuration information. If the terminal device determines that a type-1 data and a type-2 data need to be transmitted at a same time, the terminal device allocates a first transmit power for first data based on the first configuration information. In this case, a transmission performance of a system in a high-density service scenario is improved, while a transmission quality of important data is ensured.
