Abstract: A communication method for reducing resource overheads and improving decoding efficiency, is applied to a communication system. The method includes: a terminal device sends resource reservation information, where the resource reservation information is used to reserve a grant-free resource; and the terminal device sends data on an actually reserved grant-free resource.

Abstract: A frequency hopping pattern indication method and an apparatus are provided to reduce interference between users. In the method, a network device may indicate a frequency hopping pattern to a first terminal device which performs communication based on the frequency hopping pattern. The frequency hopping pattern indicates a frequency band occupied when the first terminal device performs communication at a frequency hopping moment. The first terminal device collides with any other terminal device at a maximum of one frequency hopping moment in one period. A first period corresponds to more than two frequency hopping moments and more than two frequency bands.

Abstract: The first terminal device groups to-be-sent information bits to obtain first information bits and second information bits; separately encodes the first information bits and the second information bits to obtain a first codeword sequence and a second codeword sequence; then performs interleaving processing on the first codeword sequence and the second codeword sequence based on an interleaving pattern, to obtain a first target signal; and sends the first target signal to the access network device. The access network device performs de-interleaving processing on the received first target signal based on a preset interleaving pattern, to obtain the first codeword sequence and the second codeword sequence; and separately decodes the first codeword sequence and the second codeword sequence to obtain the first information bits and the second information bits.

Abstract: A first communication apparatus receives resource configuration information from a second communication apparatus, where the resource configuration information includes a first resource that is configured by the second communication apparatus for the first communication apparatus for data transmission. The first communication apparatus releases, based on a preset condition, a second resource to which a first synchronization signal block SSB is mapped, where the second resource is a dedicated resource of the first communication apparatus, and the first resource includes the second resource.

Abstract: A terminal device obtains coding information that includes a first information bit and a second information bit. The terminal device selects, based on the first information bit, K groups from a codebook having L groups as activation groups, where both L and K are positive integers, and K is less than L. The terminal device then selects, based on the second information bit, a sequence from each of the activation groups as an activation sequence, and obtains a first sequence by superimposing the K activation sequences.
