Abstract: PURPOSE: A method and an apparatus for synchronizing a QP(Quiet Period) cognitive radio system are provided to supply QP scheduling synchronization to neighbor base stations using an in-band channel by including the information which can discriminate the in-band channel and an out-band channel. CONSTITUTION: A receiver(602) receives a QP(Quiet Period) information on a first channel from a neighbor base station, and a control unit(600) confirms an in-band channel within a first channel. In the case of the in-band channel, a QP scheduling manager(608) performs QP scheduling according to the QP information. In the case of an out-band channel, the QP scheduling management unit judges the necessity of scheduling for an out-band channel. If the scheduling for the out-band channel is required, the QP scheduling management unit relays the QP information to another neighbor base station.

Abstract: PURPOSE: A CBP packet transmitting apparatus and method in a wireless communications system based on CR(Cognitive Radio) are provided to select a proper competitive target through the analysis of surrounding WRANs and increase the SCW life cycle in a WRAN which is defeated in competition, thereby setting a high reliable SCW rule pattern while preventing collision between CBP packets. CONSTITUTION: If entering a channel, a pattern analyzer(1132) analyzes the SCW(Self Coexistence Window) rule patterns of surrounding WRANs(Wireless Regional Area Networks). In case an unoccupied SCW slot is not periodically generated, a competition selector(1134) selects a WRAN having the shortest SCW life cycle as a competitive target. A backoff timer(1136) creates a random backoff time for competition with the competitive target at a start point of time of an SCW slot in which the competitive target transmits a CBP(Coexistence Beacon Protocol) packet. If the random backoff time is expired before the reception of the CBP packet of the competitive target, a RF(Radio Frequency) transmitter(1128) transmits the CBP packet.

Abstract: A method and an apparatus for managing a channel in a cognitive radio system supporting a multi-channel are provided to efficiently use a multi-channel to a cognitive radio communication by managing spectrum according to an operation property of the multi-channel. An available channel list and an unavailable channel list are checked in database(300). A channel set occupied in the available channel list and unlicensed channel set are excluded. Available channels detected in the channels of a plurality of unclassified channel sets are added(304). A backup channel set is generated from the available channel list(306). At least one or more channel combinations are made from the backup channel set. A backup channel set is formed after arranging and determining priority of the channel combinations(308). At least one or more channel combinations among channel combinations which form the backup channel set are selected.

Abstract: An apparatus and a method for selecting a path in a broadband wireless communication system are provided to select a path by using a transmission rate with respect to a base station-terminal link and a relay-terminal link and a queue state of a base station and a repeater. A base station selects one of modes for path selection(600). The base station receives a report on an SNR(Signal-to-Noise Ratio) value obtained by measuring a radio channel state between the base station and a terminal and between a relay station and the terminal from the terminal(602). If the base station needs to receive the SNR value between the base station and the relay station(604), it receives the same from the relay station(606). If the SNR between the base station and the relay station is not required, the base station calculates a data transmission rate between the base station and the terminal and between the relay station and the terminal by using the reported SNRs between the base station and the terminal and between the relay station and the terminal(610). The base station determines whether to transmit data through a direct path from the base station or by way of the relay station(612). The base station transmits information about the determined data transmission path to the relay station and the terminal(614).
