Method of allocating wireless resource for space division multiple access communication and wireless resource allocation system of enabling the method

A method of allocating a wireless resource for a Space Division Multiple Access (SDMA) communication, the method comprising:

• recognizing a channel state of wireless channels generated among adjacent nodes including a source node, a relay node, and a destination node;
• and
• controlling at least one of an amount of channel state information fed back from the destination node to the source node according to the channel state, and a relay level of a relay signal, the relay signal being generated by relaying a source signal transmitted from the source node, by considering a ratio of the relay level to the amount of the channel state information according to the channel state.

A non-transitory computer-readable recording medium storing a program for implementing a method of allocating a wireless resource for a Space Division Multiple Access (SDMA) communication, the method comprising:

• recognizing a channel state of wireless channels generated among adjacent nodes including a source node, a relay node, and a destination node;
• and
• controlling at least one of a amount of channel state information fed back from the destination node to the source node based on the channel state, and a relay level of a relay signal, the relay signal being generated by relaying a source signal transmitted from the source node, by considering a ratio of the relay level to the amount of the channel state information according to the channel state.
