WIPO Patent Application WO/2023/066028
Kind Code:
A1
Abstract:
Embodiments of the present application provide a communication method and apparatus. The method can comprise: a terminal device obtains a target value of a first parameter, the target value of the first parameter being one of candidate values of the first parameter, the candidate values of the first parameter corresponding to device characteristics, the device characteristics comprising the type of a device and/or characteristics supported by the device, and the terminal device being a terminal device to be randomly accessed to a network device; and the terminal device receives a first message according to an RA-RNTI, the RA-RNTI being determined according to the first parameter. According to the method, parameter values corresponding to device characteristics are determined by means of a correspondence, such that it can be ensured that RA-RNTI values corresponding to different device characteristics are different; in this way, messages scrambled by the RA-RNTIs can be distinguished, such that conflicts caused by the terminal device being unable to distinguish an RACH resource during a random access process are avoided, the random access efficiency is improved, and the random access delay is reduced.
