1. An electronic equipment in a wireless communication system, comprising:
circuitry configured to
perform a channel detection process on one or more beam directions of an unlicensed spectrum, each beam direction being configured by binding two or more sub-beam directions, the two or more sub-beam directions being adjacent uplink directions around the electronic equipment;
transmit a random access preamble sequence in one or more of the two or more sub-beam directions included in the one or more beam directions in which channel detection is idle, respectively;
start a random access response window to receive a random access response message;
determine a certain beam direction of the unlicensed spectrum for transmitting an uplink transmission message according to the received random access response message; and
transmit the uplink transmission message via the determined beam direction,
wherein different beam directions or different sub-beam directions correspond to different random access preamble sequences.
