SCRAMBLING METHOD, DESCRAMBLING METHOD AND COMMUNICATION APPARATUS

WIPO Patent Application WO/2023/011008

A1

Disclosed in the present application are a scrambling method, a descrambling method and a communication apparatus. The scrambling method comprises: a first device generating a scrambling code according to a time parameter, and scrambling first information according to the scrambling code; and then the first device sending, on a first channel, the scrambled first information to a second device. In the implementation manner, a scrambling code is generated according to a time parameter, such that scrambling codes generated according to different time parameters are different. Therefore, in the case of repeated transmission, first information to be sent is scrambled according to different scrambling codes, such that information sent each time is not completely the same during multiple repeated transmissions of the first information. Since the information sent during repeated transmission is not completely the same, the possibility of a first device scrambling the same first information by using the same scrambling code within a period of time is reduced, thereby improving the anti-interference capability of the transmission of the first information, and further improving the performance of a second device receiving the first information.
