Document Type and Number:
WIPO Patent Application WO/2019/120126
Kind Code:
A1
Abstract:
The present application provides a signal processing method, apparatus and system, belonging to the field of communications. The method comprises: when a first-standard communication system and a second-standard communication system share a target frequency band, a base station of the first-standard communication system acquiring from the first-standard communication system at least one channel of signals to be sent and a spread spectrum code corresponding to each channel of to-be-sent signals; determining at least one channel of scrambling signals and a spread spectrum code corresponding to each channel of scrambling signals; spreading each channel of signals according to at least one channel of to-be-sent signals and the spread spectrum code corresponding to each channel of signals among the at least one channel of scrambling signals; processing the spread multiple channels of signals to obtain a transmission signal and sending same, the power of the transmission signal within the target frequency band being less than the power of a signal, which is obtained by performing said processing only on the spread at least one channel of to-be-sent signals, within the target frequency band. Therefore, the interference of the transmission signal on the signal in the second-standard communication system can be effectively reduced.
