    • A method and a system for allocating resources in a wireless communication system using a hybrid duplexing method are provided to effectively allocate resources correspondingly to the size of a changed cell region and improve the performance of a data system by preventing interference between neighbor cells. When a BS(Base Station) receives a CINR(Carrier to Interference and Noise Ratio) adjustment request from neighbor BSs(601), it calculates a CINR to be adjusted according to cell information of the neighbor cells managed by the neighbor BSs(603). The BS measures the use efficiency of resources allocated to downlink and uplink of frames(605), and calculates a CINR to be adjusted according to the measured use efficiency of the resources(607). The BS adjusts a CINR based on increase/decrease value of the CINR to be adjusted in the two obtained current CINRs(609).

    • PURPOSE: A receiving device of a multi-band UWB(Ultra Wideband) communication system and a receiving method thereof are provided to differently control integration times according to each sub band, in order to compensate for different path attenuations in accordance with each sub band, thereby lowering an average bit error rate while realizing a high-speed data rate. CONSTITUTION: A multi-band index generator(100) generates a multi-band index corresponding to a sub band where a receiving signal is transmitted. A multi-band frequency generator(120) generates a multi-band frequency for the sub band by corresponding to the multi-band index. A multiplier(130) outputs a signal produced by multiplying the receiving signal by the multi-band frequency. A correlation receiver(140) integrates the signal outputted from the multiplier(130) according to a set integration time, and outputs the integrated signal. A buffer(160) buffers the outputted signal such that the buffered signal can be outputted in predetermined data rate.

    • A method for configuring a code book and a method for selecting a beamforming vector in a PU2RC system are provided to improve the performance of a communication method by using an optimum code book. The 'M' number of data signals(120) to be transmitted from a base station to a mobile terminal(180) are inputted to a precoder(130). Pilot signals(140) are directly provided to a multi-antenna(150) including the M number antennas(150-1-150-M). The mobile terminal belonging to a base station(110) receives the pilot signals by using a multi-antenna(170) including the N number of antennas(170-1-170-N). Because the base station includes the multi-antenna including the M number of antennas and the mobile terminal includes the multi-antenna including the N number of antennas, there are the MxN number of downlink channels(160) from the base station to the mobile terminal. Because the pilot signals are orthogonal to each other, the mobile terminal can easily measure a state of the MxN number of downlink channels and easily search a beamforming vector that forms an optimum beam pattern by using its code book.

System resources are time-divided into a TDD section and an FDD section. The TDD section is time-divided into a TDD downlink section and a TDD uplink section. The FDD section is frequency-divided into an FDD uplink band and an FDD downlink band.

    • A method for relaying a data packet in a downlink in a wireless communication system is provided to enable RSs, appointed by a BS, to determine whether they can perform relay transmission by referring to their signal intensity if the BS appoints the RSs, which will be used in the relay transmission, and the notifies the fact, thereby removing the necessity of a special algorithm for selecting optimum RSs and reducing signaling overhead required to be transmitted through the RS. A method for relaying a data packet in a downlink in a wireless communication system comprises the following steps. A data packet is relayed by RSs(Relay Stations), which have signal intensity greater than a threshold value among RSs appointed by a BS(Base Station)(S303,S305). SSs(Subscriber Stations) determine whether to receives the data packet from the BS or from an RS, by referring to signal intensity between the SSs and the BS and signal intensity between the SSs and the RS(S307). And then, the SSs feed channel information corresponding to the determination result back to the BS and make the data packet transmitted(S309~S319).
    • 提供了一种在无线通信系统中中继下行链路中的数据分组的方法,以使得由BS指定的RS可以通过参考它们的信号强度来确定它们是否可以执行中继传输,如果BS指定RS 用于中继传输,并通知事实,从而消除了选择最佳RS的特殊算法的必要性,并减少了要通过RS发送的信令开销。 一种用于在无线通信系统中中继下行链路中的数据分组的方法包括以下步骤。 数据分组由RS(中继站)中继,RS(中继站)在由BS(基站)指定的RS之间具有大于阈值的信号强度(S303,S305)。 SS(订户站)通过参考SS和BS之间的信号强度以及SS和RS之间的信号强度来确定是从BS还是从RS接收数据分组(S307)。 然后,SS将与确定结果相对应的信道信息返回给BS并使数据分组发送(S309〜S319)。
