APPARATUS AND METHOD OF DATA TRANSMISSION AND RECEPTION USING MULTI-PATH
First Claim
1. A method of transmitting data by using a multi-path including a direct path in a line of sight (LOS) and at least one relay path formed between a transmission end and a reception end by cross-selecting one or more available paths determined based on whether a data receipt acknowledge control signal is received from the multi-path.

Abstract
Provided are a method and apparatus for transmitting/receiving data by using a multi-path. The multi-path is established between two transceivers, data is transmitted via each path at a predetermined time, a data receipt acknowledge control signal ACK of each path is received, and a path by which the data receipt acknowledge control signal ACK is not received is determined. Therefore, the path by which the data receipt acknowledge control signal ACK is not received is not used any further but data is transmitted via a path by which the data is previously transmitted, so that the data can be transmitted even if a line of sight (LOS) of the two transceivers comprising a directional antenna is blocked by a person or an obstacle.

- 1. A method of transmitting data by using a multi-path including a direct path in a line of sight (LOS) and at least one relay path formed between a transmission end and a reception end by cross-selecting one or more available paths determined based on whether a data receipt acknowledge control signal is received from the multi-path.

12. 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. - View Dependent Claims (13, 14, 15)

16. 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. - View Dependent Claims (17)

- 18. An apparatus for transmitting data using multi-path including a direct path in an LOS and at least one relay path formed between a transmission end and a reception end by cross-selecting one or more available paths determined based on whether a data receipt acknowledge control signal is received from the multi-path.

25. 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. - View Dependent Claims (26, 27)
