Title:
DATA TRANSMISSION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/042215
Kind Code:
A1
Abstract:
Disclosed by embodiments of the present application are a data transmission method and an apparatus, used, during a passive transmission process, for dynamically determining a set of codebooks corresponding to each sub-block, thereby reducing the storage overhead of a communication apparatus. Embodiments of the present application provide a data transmission method, specifically comprising: upon the first communication apparatus preparing to transmit data, the first communication apparatus obtaining information-bit information of the i-th sub-block, the information-bit information of said i-th sub-block comprising information bits of the i-th sub-block and the information-bit length of the i-th sub-block, i being a positive integer; at the same time, the first communication apparatus obtaining the matrix order M of itself in an RM corresponding to the i-th sub-block, M being a positive integer; then, according to the M, the first communication apparatus obtaining a first P matrix and a first b vector of the generated RM; then, according to the first P matrix and the first b vector, the first communication apparatus generating an RM sequence corresponding to the i-th sub-block; finally, the first communication apparatus outputting the RM sequence corresponding to the i-th sub-block.
