Abstract: 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).

Abstract: A PN(Pseudo Noise) acquisition device in a spread-spectrum communication system and a method thereof are provided to more improve a detection probability of a correct hypothesis when a search window-based PN acquisition technique is used during synchronization of a receiver, thereby reducing PN acquisition time. Plural accumulators(309,311) output coherent and non-coherent accumulated hypothesis energy values of received signals. An energy detector(321) detects plural time hypotheses among all time hypotheses within a search window, and outputs plural corresponding hypothesis energy values. A threshold value comparator(323) compares the size of the hypothesis energy values with at least one predetermined threshold value, and outputs the compared results. A controller(325) controls accumulating operation of the accumulators(309,311), and decides that PN acquisition is successful if a particular time hypothesis having a hypothesis energy which is more than the threshold value is confirmed among the detected hypothesis energy values.
