发明名称 Apparatus and method for transmitting and receiving data using multi-path in wireless communication system of distributed MAC
摘要 Provided is an apparatus and method for transmitting and receiving data using multiple paths in a wireless communication system using a distributed Media Access Control (MAC). More particularly, provided is an apparatus and method for transmitting and receiving data that may select a path with a better channel status from multiple paths that include a direct path using a Line of Sight (LOS) and a relay path passing through a relay apparatus, in a wireless communication system that may transmit data via the LOS using a distributed MAC and a directional antenna.

主权项 1. A method of transmitting and receiving data in a wireless communication system, the method comprising: transmitting and receiving the data to and from a relay apparatus or a destination device in any one of an alternative mode to transmit and receive the data alternating between using a direct path and a relay path and a normal mode to transmit and receive the data via any one of the direct path and the relay path; changing a data transceiving path to an available data transceiving path or to another data transceiving path with a channel status better than a currently using data transceiving path, based on channel status information of the data transceiving path; and periodically verifying a channel status of a previous data transceiving path, wherein the changing is performed in a path change interval, and data is transmitted after a period of time is elapsed from a start point in time of the path change interval.
