Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/188000
Kind Code:
A1
Abstract:
The present application provides a communication method and a communication apparatus. Adjusting a modulo interval, determining a disturbance vector, and unifying modulo intervals of a terminal device facilitate reducing modulus loss of a precoding algorithm, stabilizing and increasing the signal-to-noise ratio of a receiving end, and improving system performance gain. The method comprises: a network device sends first information to a terminal device, the first information being used for indicating at least one of a first parameter, a second parameter, or a third parameter, the first parameter comprising a parameter for increasing or decreasing a modulo interval, the second parameter comprising a parameter for maximizing a signal-to-interference-plus-noise ratio, the third parameter comprising a modulation and coding scheme (MCS), and the MCS being used for the terminal device to determine the modulo interval, and correspondingly, the terminal device receives the first information; and the terminal device receives or sends a signal according to the first information.
