Abstract: PURPOSE: A winner node selecting method in an OFDM(Orthogonal Frequency Division Multiplexing) based wireless mesh system is provided to effectively select winner nodes by establishing a parameter related to an algorithm for minimizing collision between competition nodes. CONSTITUTION: A node collects parameters which are necessary to select mesh data for the nodes of a second hole section. The node uses the nodes of the second hole section as competition nodes. The node determines a winner node for each sub-channel. When the winner node is determined for a first sub-channel of the sub-channels, the node excludes the nodes of a first hole section from the competition node.

Abstract: A method for shortening the hand-over delay by using an L2 trigger and a relay station adapting the same are provided to start the L3 hand-over before the start of the L2 hand-over, thereby reducing the delay time of the hand-over. The signal quality of links connected with a mobile station is measured(S130). Thereafter, an interval estimation is performed through the constant number of samples constructed by the measured signal quality(S140). As the result of the interval estimation, when the signal quality is below the constant critical value, the layer 2 trigger for starting the layer 3 hand-over is generated(S150). In the interval estimation process, the number of samples, the critical value and the confidence interval are set. Thereafter, the interval estimation is performed by means of the confidence interval about the measurement values of the signal quality of the links as much as the number of samples. Thereafter, a process for discriminating whether the lower limit value of the confidence interval by the interval estimation is below the initial value is performed.

Abstract: A method for selecting an optimum path in an MMR communication system is provided to enable RSs within a cell to measure a correlation value and a CQI value of a CQICH for a UE and report the values to an MMR-BS when the UE registered in the MMR-BS enters the RS region, and enable the MMR-BS to set a proper RS path, thereby providing the UE with a data service of high transmission efficiency. If a UE(User Equipment) is registered within a cell, an MMR-BS(Multi-hop Mobile Relay-Base Station) allocates a CQICH(Channel Quality Indicator Channel) to the UE and loads a CQICH_Allocation_IE on a map before broadcasting the IE(S550). The UE1 periodically transmits a measure value CQI of a downlink preamble to the allocated CQICH(S555). The MMR-BS measures and stores the maximum correlation value and CQI value for CQICH #0 of the UE1, and compares the stored values with correlation values and CQI values for CQICH #0 reported from RSs(Relay Systems)(S570). The MMR-BS determines an RS, having the maximum value among the correlation values measured and reported by the RSs, as a data transmitting/receiving path of the UE1(S585).

A method for configuring a feedback region in a wireless communication system includes the steps of: assigning a first feedback region on an access region where data is transmitted from a mobile station to a base station(S715); and assigning a second feedback region corresponding to the first feedback region on a relay region where data is transmitted from a repeater to the base station(S730). A position of feedback channels included in the first feedback region is the same with a position of feedback channels included in the second feedback region. A size of the first feedback region is the same size of the second feedback region.
