RANDOM ACCESS METHOD AND RANDOM ACCESS SYSTEM FOR TERMINAL IN HIGH-SPEED MOBILE ENVIRONMENT |
摘要 |
A random access method and random access system for a terminal in a high-speed mobile environment. The method comprises: selecting a random access preamble format according to a preset cell coverage radius target value; judging whether using a pre-configured restricted set of cyclic shift quantities satisfies the requirements of the cell coverage radius target value under the selected random access preamble format; if not satisfied, selecting a cyclic shift quantity which satisfies the requirements of the cell coverage radius target value from a pre-configured unrestricted set of cyclic shift quantities; and generating a random access signal according to the cyclic shift quantity and a pre-configured mother code, and performing access using the random access signal. Through the above technical solution, the embodiments of the present invention provide a more perfect random access method and random access system for a terminal in a high-speed mobile environment. |
