摘要： This application provides a data transmission method and communications apparatus, to improve transmission efficiency. The method may include obtaining, by a MAC entity of a first communications device from an upper layer, first data on each of at least one first logical channel and second data on each of at least one second logical channel, where a service type or a destination address of the first data is different from a service type or a destination address of the second data. The method may also include generating, by the first communications device, a MAC PDU, where the MAC PDU includes the first data on each first logical channel and the second data on each second logical channel; and sending, by the first communications device, the MAC PDU through a direct link.

摘要： This application provides a direct link data transmission method, a terminal device, and a network device. The method includes: receiving, by a first terminal device, first configuration information sent by a network device, where the first configuration information includes information about a transmission resource set, and the transmission resource set is a transmission resource set shared between a second terminal device that uses a centralized scheduling transmission mode and a third terminal device that uses a distributed transmission mode; detecting, by the first terminal device, a load level of a resource unit in the transmission resource set based on the information about the transmission resource set; and sending, by the first terminal device, report information to the network device based on the load level, where the report information includes information about an occupied resource unit and/or information about an available resource unit in the transmission resource set. A transmission resource allocated to the first terminal device can be prevented from colliding with a transmission resource of another terminal device, so that communication quality of a terminal device and user experience is improved.

摘要： 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.

摘要： This disclosure provides a service transmission method. The terminal device determines, based on a relationship between radio resource information and transmission characteristic information, a first transmission resource set supporting a first transmission characteristic, when determining to transmit service data by using the first transmission characteristic, selects a direct link transmission resource from the first transmission resource set supporting the first transmission characteristic to transmit the service data, and transmits the service data on the selected direct link transmission resource.

摘要： This application provides a service data transmission method and apparatus, and the method includes: obtaining first configuration information, where the first configuration information includes a first service feature parameter and a first resource parameter corresponding to the first service feature parameter; obtaining to-be-sent service data and a second service feature parameter corresponding to the to-be-sent service data; determining, based on the first service feature parameter, the second service feature parameter, and the first resource parameter, a second resource parameter for transmitting the to-be-sent service data; selecting, based on the second resource parameter, an available resource for transmitting the to-be-sent service data; and transmitting the to-be-sent service data by using the available resource. In this way, the service feature parameter of the service data is considered while the available resource is determined, to determine the resource parameter based on the service feature parameter, thereby better satisfying a delay requirement of a low-delay service.

摘要： This application provides a data transmission method and apparatus. The method includes: obtaining, by a terminal, information used to indicate a first condition; obtaining to-be-transmitted data; and when the first condition is met, sending, by the terminal over a sidelink, the to-be-transmitted data that is on a first logical channel by using a first carrier frequency and the to-be-transmitted data that is on a second logical channel by using a second carrier frequency. In this method, the same data is sent, over the sidelink, on different carrier frequencies by using two logical channels, and a receiving device can receive the same duplicate data, thereby improving data transmission reliability.
