RANDOM ACCESS METHOD, RANDOM ACCESS DEVICE, AND TERMINAL
First Claim
1. A random access method for a Long Term Evolution (LTE) system operating on an unlicensed frequency band, comprising:
- determining a format of a random access preamble sequence;
determining a channel detection mode for a random access channel according to the format of the random access preamble sequence;
detecting the random access channel according to the determined channel detection mode; and
transmitting the random access preamble sequence via the random access channel when it is detected that the random access channel is in an idle state.

Abstract
A random access method, device, and terminal for an LTE system operating on an unlicensed frequency band. The method comprises: determining a format of a random access preamble sequence; determining, according to the format of the random access preamble sequence, a channel detection mode for a random access channel; performing, according to the determined channel detection mode, detection on the random access channel; and upon detection of the random access channel being in an idle state, sending the random access preamble sequence via the random access channel.
