Title:
RANDOM ACCESS METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/247721
Kind Code:
A1
Abstract:
The present application provides a random access method, comprising: determining a first time difference T1, the first time difference T1 being used for indicating a time difference between the time domain position of a first signal received from a network device and a first fixed time, the first fixed time being determined according to a global navigation satellite system 1 pulse per second (GNSS 1pps) signal; determining communication delay Td according to the first time difference T1; and sending an uplink physical random access channel (PRACH) preamble sequence to a network device according to the communication time delay Td. According to the technical solution of the present application, by determining the communication delay with the network device and sending the PRACH preamble sequence according to the communication delay, the terminal device can quickly and stably complete random access.
