Claim 12:
13. A wireless communication method executed by electronic equipment in a wireless communication system, comprising:
performing 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; and
transmitting 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;
starting a random access response window to receive a random access response message;
determining a certain beam direction of the unlicensed spectrum for transmitting an uplink transmission message according to the received random access response message; and
transmitting 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.
