Title:
COMMUNICATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/202430
Kind Code:
A1
Abstract:
Provided in the present application are a communication method, system and apparatus. The communication method comprises: generating a first sequence, wherein the first sequence is determined according to a complete complementary code set, the complete complementary code set is determined on the basis of a Gray partner and a Hadamard matrix and by means of Kronecker product operation, and the first sequence is used for channel estimation; and sending the first sequence. By means of the method, the use of a P-matrix is avoided during the process of constructing a multi-stream zero-correlation sequence, thereby reducing the complexity of sequence construction, shortening the length of the sequence, reducing the amount of resources occupied, and also reducing the delay of channel estimation and improving the efficiency of channel estimation.
