Method and apparatus for setting detour path in wideband high frequency wireless system using centralized mac protocol

An operating method of a destination device, the method comprising:

• performing a first beamforming process with a relay device, and
• perform a second beamforming process with a source device,
• wherein the source device is configured to:
• perform a third beamforming process with the relay device;
• obtain a channel status of a detour path between the source device, the relay device, and the destination device;
• obtain a channel status of a direct path between the source device and the destination device;
• compare information associated with the channel status of the detour path with the information associated with the channel status of the direct path;
• and
• transmit data to the destination device via whichever one of the detour path and the direct path has a better channel status.
