Title:
RANDOM ACCESS METHOD AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/204171
Kind Code:
A1
Abstract:
Disclosed is a random access method, applied to the field of communication. The method comprises: a terminal device sends, to a network device, a first message for establishing a wireless connection, and the terminal device receives a connection response sent by the network device, the connection response comprising information of a first polarization parameter; and when accessing the network device according to the connection response, the terminal device confirms, according to the information of the first polarization parameter comprised in the connection response, whether the terminal device is qualified to access the network device. By introducing this dimension of the polarization parameter in a random access process, the capacity of preamble is increased, the problem that the network device cannot identify the terminal device to which collision occurs is mitigated, and the efficiency of establishing a communication connection between the terminal device and the network device is improved.
