Abstract: A first node obtains first power control information (PCI) based on an information security protection requirement, a maximum transmit power of a second node, and channel information between the first and second nodes. The first PCI is a piece of PCI that is obtained through prediction and that maximizes a signal-to-noise ratio of a received signal of the first node when the information security protection requirement is met. The received signal includes a signal from the second node. In addition, the first node sends the first PCI to the second node, where the first PCI is used by the second node to generate a first signal. The first node then receives the first signal from the second node, where the first signal includes data information and security protection information, and the security protection information is used to protect information security of the data information.

Abstract: Embodiments of this application provide a communication method and apparatus, to reduce complexity of a polar code construction process. The method includes: obtaining a to-be-encoded bit sequence, where the to-be-encoded bit sequence includes K information bits, and K is an integer greater than 0; determining a first sequence, where positions of the K information bits in the first sequence are determined based on a second sequence corresponding to a target code rate and a value of K, the second sequence is used to represent selection priorities of N0 bit positions, and N0 is an integer greater than K; performing polar code encoding on the first sequence to obtain a third sequence; and sending the third sequence. The second sequence is designed for a constant code rate, and a same sequence may be used to construct a series of polar codes having a same code rate and different lengths.

Abstract: A method includes: obtaining first semantic information corresponding to data; converting the first semantic information into second semantic information, where the second semantic information belongs to common semantic information, and the common semantic information is a unified description of same semantics that is provided by different devices; and sending the second semantic information. Based on the method provided in this application, when a semantic extraction model of a transmit device and a semantic understanding model of a receive device are not jointly trained, accuracy of semantic communication between the transmit device and the receive device may be ensured by converting local semantic information into common semantic information.

Abstract: This application provides example communication methods and a related apparatuses. An example communication method may be used for a first processing entity of a first communication device. The example method includes the first processing entity sending a first registration request to a second entity, where the first registration request includes a first identifier which indicates one or more of the following information of the first processing entity: model information or data information. A model parameter of the second entity can be adjusted based on a real-time environment parameter. The first processing entity receives a first registration response sent by the second entity, where the first registration response indicates an input parameter of the second entity. The first processing entity sends a first response acknowledgment, where the first response acknowledgment indicates whether an output parameter of the first processing entity matches the input parameter of the second entity.

Abstract: This application provides example concatenated code encoding and decoding methods. In one example method, polar code encoding is performed on a to-be-encoded message bit sequence based on a frozen bit set and a message bit set that are of a first polar code, to obtain a first encoded code word whose length is N_o. The first encoded code word is interleaved to obtain a second encoded code word, and optimized low-density parity-check (LDPC) code encoding is performed on the second encoded code word to obtain a concatenated code word. Interleaving includes both outer interleaving and inner interleaving. The concatenated code word is then outputted.

Abstract: A communication method and a communication apparatus. A terminal device obtains a first SSB. The terminal device sends a random access preamble corresponding to the first SSB. The random access preamble is carried at a first time domain position. The first time domain position is associated with a timing offset value. The timing offset value is determined based on a round-trip delay between the network device and a first position in an area covered by the network device.
