Abstract: A low density parity check (LDPC) channel encoding method is used in a wireless communications system. A communication device encodes an input bit sequence by using an LDPC matrix, to obtain an encoded bit sequence for transmission. The LDPC matrix is obtained based on a lifting factor Z and a base matrix. The base matrix may be one of eight exemplary designs. The encoding method can be used in various communications systems including fifth generation (5G) telecommunication systems, and can support various encoding requirements for information bit sequences with different code lengths.

Abstract: A method includes: A second node sends a prior distribution of a parameter in a federated model to at least one first node. After receiving the prior distribution of the parameter in the federated model, the at least one first node performs training based on the prior distribution of the parameter in the federated model and local training data of the first node, to obtain a posterior distribution of a parameter in a local model of the first node. After the local training ends, the at least one first node feeds back the posterior distribution of the parameter in the local model to the second node, so that the second node updates the prior distribution of the parameter in the federated model based on the posterior distribution of the parameter in the local model of the at least one first node.

Abstract: Embodiments of this application provide a communication method and apparatus. The method includes: A first terminal performs integrity protection verification on a received RRC message; and when the integrity protection verification fails, an RRC layer of the first terminal sends a first indication and an identifier of a second terminal to an application layer of the first terminal, where the first indication and the identifier of the second terminal are used by the application layer to disconnect a unicast connection between the first terminal and the second terminal. Based on this solution, when the integrity protection verification performed by the first terminal on the received message fails, the RRC layer of the first terminal may report the first indication and the identifier of the second terminal to the application layer, to trigger the application layer to disconnect the unicast connection between the first terminal and the second terminal.
