Title:
WIRELESS COMMUNICATION METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/088174
Kind Code:
A1
Abstract:
Disclosed in the present application are a wireless communication method, apparatus, and system. The wireless communication method comprises: a transmitter generating a reference signal according to a reference signal sequence of a length M, wherein the reference signal sequence is generated according to a basic sequence configuration, the basic sequence configuration comprises the length N ZC of a Zadoff-Chu sequence and the value of the root, where N ZC>M, and the values of M and N ZC are positive integers; the transmitter transmitting uplink data, the uplink data carrying the related reference signal; after a receiver receives the uplink data and the reference signal, performing channel estimation by using the reference signal and demodulating the uplink data. The technical solution of the present application can be used so that the PAPR of uplink data is equal to or close to that of a reference signal and both are extremely low; the reference signal will not limit the non-linear PA output power, and the output power of the transmitted data and that of the transmitted reference signal are higher after PA, thereby improving the communication performance of a system.
