Title:
METHOD AND APPARATUS FOR TRANSMITTING MESSAGE SIGNATURE
Document Type and Number:
WIPO Patent Application WO/2023/109546
Kind Code:
A1
Abstract:
Provided in the present application are a method and apparatus for transmitting a message signature. The method for transmitting a message signature comprises: generating second information on the basis of first information, anti-replay information and a first key, wherein the first information is a random access process message or a system broadcast message, and the second information is used for verifying the validity of the first information; combining the first information with the anti-replay information and then performing encoding and modulation to obtain a first signal, and modulating the second information to obtain a second signal; superimposing the first signal and the second signal to generate a first superimposed signal; and sending the first superimposed signal. In the present application, first information, which is required to be sent, and second information, which is used for verifying the first information, are transmitted by means of the same time-frequency resource, and thus no additional bandwidth needs to be occupied, such that the overheads required for transmitting a message signature can be reduced.
