Title:
WIRELESS COMMUNICATION CONTROL INFORMATION TRANSMISSION METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/035518
Kind Code:
A1
Abstract:
Disclosed in the present application is a wireless communication control information transmission method. The method includes the following steps: adjusting the amplitude of a multi-carrier signal, so as to generate a multi-carrier on-off keying signal; and the multi-carrier on-off keying signal being used for carrying control information. The means of adjusting the amplitude of the multi-carrier signal involves at least one of the following: generating the multi-carrier on-off keying signal by means of controlling the amplitude of a first preset symbol set in a data frame of the multi-carrier signal; generating the multi-carrier on-off keying signal by means of truncating the length of a cyclic prefix of the data frame of the multi-carrier signal; generating the multi-carrier on-off keying signal by means of reducing the transmission power of a second preset symbol set in the data frame of the multi-carrier signal or reducing the number of carriers; and generating the multi-carrier on-off keying signal by means of controlling an amplitude change within a symbol of the multi-carrier signal. Further included in the present application is an apparatus to which the method is applied. By means of the present application, the problem of an existing method and device not being applicable to a multi-carrier system is solved; and the present application is particularly applicable to a cellular wireless mobile communication system.
