Abstract: An example communication method includes that a first terminal device receives through a first path a first data packet from a second terminal device. The first terminal device receives through a second path a second data packet from a second terminal device, where the first path has a mapping relationship with the second path. The first terminal device transmits, based on the mapping relationship, the first data packet and the second data packet to a same aggregation protocol layer entity to perform data aggregation processing.

Abstract: Communication methods and apparatuses to reduce a transmission delay of a multicast message are described. A first radio access network device receives a first message from a terminal device on a radio bearer or a first message from a second radio access network device. The first radio access network device multicasts the first message through a first air interface.

Abstract: The application provides a channel encoding method, an encoding apparatus, and a system. A bit sequence X1N is output by using X1N=D1NFN, where D1N is a bit sequence obtained after an input bit sequence u1N is encoded based on locations of K to-be-encoded information bits in an encoding diagram that has a mother code length of N, u1N is a bit sequence obtained based on the K to-be-encoded information bits, and FN is a Kronecker product of log2 N matrices F2. A design considers that the locations of the K to-be-encoded information bits in the encoding diagram that has a mother code length of N include a row location index set H of the information bits in the encoding diagram and a layer location index set M of the information bits in the encoding diagram, where 0≤H≤N, and 0
