Apparatus and method of data transmission and reception using multi-path

A method of receiving data using a multi-path, comprising:

• receiving the data, which is cross-selected and transmitted, according to a previously established rule, from one or more available paths determined based on whether a data receipt acknowledge control signal is received among the multi-path including a direct path in an LOS and at least one relay path formed between a transmission end and a reception end;
• verifying the received data and extracting path information from the verified data;
• and
• generating a data receipt acknowledge control signal and transmitting the data receipt acknowledge control signal via a path included in the extracted path information.

A multi-path managing method used to transmit/receive data, the method comprising:

• preparing a list of one or more available paths among a multi-path including a direct path in an LOS and at least one relay path formed between a transmission end and a reception end;
• deleting a path by which a data receipt acknowledge control signal with regard to transmitted data is not received among the one or more available paths that are cross-selected according to a previously established rule from an available path list, and registering the deleted path in a delete path list;
• and
• re-registering the deleted path in the available path list if the data receipt acknowledge control signal with regard to the data transmitted via the deleted path is received after a predetermined period of time passes.

An apparatus for receiving data by using a multi-path, the apparatus comprising:

• a data receiving unit receiving the data, which is cross-selected and transmitted, according to a previously established rule, from one or more available paths determined based on whether a data receipt acknowledge control signal is received among the multi-path including a direct path in an LOS and at least one relay path formed between a transmission end and a reception end;
• a data verifying unit verifying the received data and extracting path information from the verified data;
• and
• a data receipt acknowledge control signal generating unit generating a data receipt acknowledge control signal with regard to data that is transmitted via a path included in the extracted path information.
