Patent ID: 10727915

Abstract:
This application relates to the mobile communications field, and in particular, to a data processing technology in a wireless communications system. A data processing method includes: generating, by a transmitting device based on a stream of bits, one layer of modulation symbol sequence that includes N modulation vectors, any modulation vector Ai includes U modulation symbols, U≥2, N≥i≥1, and N is a positive integer; and processing, by the transmitting device, the modulation vector Ai using a matrix Bi to generate a modulation matrix yi, each modulation matrix includes T elements in a first dimension, T is a quantity of space domain resources, T≥2, and the modulation matrix yi is used to map the stream of bits stream onto the T space domain resources. According to the solutions provided in this application, space diversity can be implemented in code domain, so that transmission reliability is improved.
