A control message processing method and a control message processing apparatus using the method on a wireless mesh network are provided where a neighbor solicitation (NS) information is generated by extracting a part or an entire NS message, the NS message having been generated to request a medium access control (MAC) address of a destination node. A modified route request (RREQ) message, including the NS information, is generated to request the MAC address of the destination node and a routing path to the destination node, and is broadcasted.

Control message processing method in wireless mesh network and control message processing apparatus using the method

A method and system for performing re-association in a WLAN mesh network are provided. A mobile node transmits authentication request information to an old node via a new node along with a mesh re-association request message for re-association of the mesh network. Upon receiving the mesh re-association request message, the old node performs re-association and authentication according to the mesh re-association request message, and transmits a mesh re-association reply message to the mobile node via the new node.

Method and system for performing re-association due to handover in a WLAN mesh network

Provided is a constellation rotation relay system and constellation rotation relay method which can acquire full diversity gain by performing constellation rotation for a channel matrix in a relay network when configuring a virtual MIMO channel. The constellation rotation system includes a matrix creator for creating a symbol matrix by configuring a symbol transmitted in parallel from a source of a relay network; and a constellation rotation unit constellation rotating the symbol in the symbol matrix by adding a constellation rotation matrix to the created symbol matrix.

Constellation rotation relay system and constellation rotation relay method

A method and system of relaying data are provided. The data is encoded into a turbo codeword by using a convolutional turbo code encoder, and the turbo codeword is transmitted from a source to a relay and a destination after puncturing by a first puncturing operation. The first punctured turbo codeword which is received in the relay is de-punctured and regenerated in a decoding operation and the regenerated turbo codeword is transmitted from the relay to the destination in punctured form after puncturing by a second puncturing operation. The punctured turbo codewords received from the source and the relay by the destination are totaled together as a totaled single turbo codeword and the totaled single turbo codeword is completely decoded to recover the data.

Method and system of relaying data

A wireless-fidelity (Wi-Fi) interfacing method and a Wi-Fi interfacing system are provided. The Wi-Fi interfacing method includes: determining an interfacing operation mode related to a received packet, in interoperation with the receiving of the packet; and processing the packet via a single Wi-Fi interface, according to the determined interfacing operation mode. The Wi-Fi interfacing system includes: an operation mode determination unit determining an interfacing operation mode related to a received packet, in interoperation with the receiving of the packet; and a packet processing unit processing the packet via a single Wi-Fi interface, according to the determined interfacing operation mode.

Method and system for supporting multi mesh operation modes using single Wi-Fi interfacing

An apparatus and method of saving power using location information, which can control power consumption of a mobile terminal in a sparse cell environment is provided. The power saving apparatus using location information comprises a transceiver for receiving a location information set from a base station having the stored location information set, a controller for receiving the location information set from the transceiver, and activating any one of a plurality of modes by using the location information set, where each of the plurality of modes utilizes a different power consumption level.
