Abstract: Embodiments of this application provide a data transmission method, an apparatus, and a system. The method includes: obtaining a transmission pattern combination of data including at least two data packets, where the transmission pattern combination includes at least two transmission patterns, and the transmission pattern indicates a transmission manner and/or a processing manner of the data packet; and transmitting the data based on the transmission pattern combination, where the transmission pattern is determined for each data packet in correspondence to a matching condition, and the matching condition is associated with feature information of the data packet. According to the foregoing method, a manner in which a data packet is processed and transmitted can be accurately controlled, so that data packets with different features are processed and transmitted by using appropriate transmission parameters, to ensure service transmission reliability and implement effective resource utilization.

Abstract: A communication method and apparatus are provided. The method includes a terminal device that receives first configuration information and second configuration information from a network device. The first configuration information is used to configure a primary RLC group, and the second configuration information is used to configure a secondary RLC group. The terminal device determines the primary RLC group and the secondary RLC group based on the first configuration information and the second configuration information. According to the foregoing solution, the network device may configure the primary RLC group and the secondary RLC group for the terminal device, and the primary RLC group and the secondary RLC group each may include at least one RLC entity.

Abstract: A data transmission method and an apparatus are provided. The method includes determining, by a first communication apparatus, that transmission of a first data packet has failed, the first data packet being transmitted in a first transmission manner; and sending, by the first communication apparatus, P data packets after the first data packet, the P data packets being sent in a second transmission manner, P is an integer greater than or equal to 1, and a second transmission reliability corresponding to the second transmission manner is greater than the first transmission reliability corresponding to the first transmission manner. In this way, because the first communication apparatus sends the P data packets after the first data packet in the second transmission manner, transmission reliability of the P data packets is improved, so that successful transmission of the P data packets can be effectively ensured, and service interruption can be avoided.
