摘要： An apparatus and a method for estimating the channel state of each link in a wireless relay network having fixed RSs are provided. A source estimates a channel of a source-RS link and a channel of a source-destination link using pilot signals received from an Relay Station (RS) and a destination and the source monitors reception of a pilot signal including channel state information of an RS-destination link from the RS. Upon receipt of the pilot signal, the source estimates a channel of the RS-destination link using the pilot signal and the channel state information of the RS-destination link.

摘要： An apparatus and method for retransmitting data using an RS in a multi-hop network are provided. When retransmitting data in a BS, the BS transmits data and activates a timer therefor. The BS monitors receipt of a response message for the data until the timer expires. The BS receives the response message and, if it is a Non-Acknowledgement (NACK), determines whether an RS has successfully received the data with a BSN associated with the NACK. If the RS has not successfully received the data, the BS retransmits the data. If the RS has successfully received the data, the BS determines a retransmission entity. If the retransmission entity is the RS, the BS transmits a control message commanding retransmission to the RS, and if the retransmission entity is the BS, the BS retransmits the data.

摘要： A source node of a communication system selects one of a direct mode, a multi-hop mode, and a superposition mode as a transmission mode to be used for signal transmission from the source node to a destination node, taking into account data rates for a link between the source node and the destination node, a link between the source node and a delay node, and a link between the relay node and the destination node, thereby increasing the data rate, i.e., the throughput, of the entire communication system.

摘要： Automatic Repeat reQuest (ARQ) apparatus and method of a Multiple Input Multiple Output (MIMO system are provided. The ARQ method includes decoding, when one or more packets are received, the received packets and trying to detect the decoded packets; and storing, when error is detected from the packets, the corresponding error packet, requesting a transmitter to retransmit N-ary packets from which the error is detected and to transmit (M-N)-ary new packets when the number of the error packets N is smaller than the total number of the transmitted packets M. Accordingly, the error rate of the retransmitted data can be minimized, the number of retransmissions can be decreased, and the overall data transmission rate can be raised.

摘要： A hybrid forwarding apparatus and method for cooperative relaying in an OFDM network are provided. In a hybrid forwarding apparatus in a relay terminal, a forwarding scheme selector selects a forwarding scheme for transmission. An amplify and forward (AF) block amplifies data received from the forwarding scheme selector, if an AF scheme is selected. A decode and forward (DF) block decodes and encodes data received from the forwarding scheme selector, if a DF scheme is selected. A multiplexer provides the output data of the AF block and the DF block to an OFDM modulator.
