Abstract: PURPOSE: A method and a device for cell reselection of mobile terminal are provided to reflect a priority setting of proceeded signal strength after scaling signal strength of femto cell to perform cell reselection of the femto cell. CONSTITUTION: If a signal strength of reference macro cell BS(Base Station) is bigger than a signal strength of femto cell BS, a terminal performs scaling signal strength of the femto cell BS(S355). The terminal determines a priority about cell selection according to a signal strength processed by the femto cell station and a signal strength of the standard macro cell base station(S325). The terminal selects a BS which is highest priority as a cell reselection target(S340).

Abstract: PURPOSE: A method for automatically searching a low-power BS supporting the access of registered users in a mobile communication system and a device thereof are provided to reduce battery consumption and unnecessary gap allocation of a terminal. CONSTITUTION: A white list stores the CSG ID of CSG cells in which a terminal is connectable. An automatic CSG cell searcher checks the requirement of automatic searching about the CSG cell. If an automatic searching is not required, the automatic CSG cell searcher turns off automatic CSG cell search function of the terminal by emptying the white list(203). If an automatic searching is required, the automatic CSG cell searcher turns on automatic CSG cell search function of the terminal by updating the white list(207).

Abstract: A system for allocating uplink resources in a communication system and a method thereof are provided to make a base station change and assign an uplink resource, which is exclusively assigned to a mobile station early, in case a mobile station requests it. If a base station detects the fact that it has to provide the service of a specific service quality class to a mobile station, it transmits the first uplink resource allocation information and then assigns the first uplink resource to the mobile station as an exclusive resource(613,615). The base station receives an uplink resource allocation request(617), and then checks whether the uplink resource to be assigned to the mobile station exists(619). If so, the base station transmits the second uplink resource allocation information and then assigns the second uplink resource to the mobile station as an exclusive resource(621,623). The base station release the first uplink resource allocation(625).

Abstract: An apparatus and a method for controlling power in a wireless communication system are provided to control idle mode and sleep mode of a mobile terminal. In case communications is not performed, a terminal(201) transmits the sleep require-message to the repeater station(203) in order to reduce the power loss(211). In case the sleep mode change over of the terminal is applied, the repeater station determines the management information in which the terminal operates to the sleep mode in consideration of the sleep mode management information which the terminal requests(213). The repeater station transmits the process time delay information of the sleep mode management information of the terminal and repeater station are transmitted to the base station(215). The base station transmits the sleep administration response message to the repeater station if the sleep management message is received without error(217).

Abstract: An interference cancellation device in a multi-antenna system and a method therefor are provided to transmit signals by considering interference between users in the same cell and neighboring cells, thereby cancelling interference of the neighboring cells and interference between the users included in the same cell. A receiving end confirms whether signals are received from a transmission end(701). If so, the receiving end estimates interference of neighboring cells and available channels with the transmission end by using a pilot signal included in the received signals(703). The receiving end cancells the interference of the neighboring cells included in the received signals(705). The receiving end feeds back interference information with the transmission end to the transmission end(707).

Abstract: A method for dynamically allocating channels in a multi-cell downlink system is provided to increase performance about throughput per unit area as compared to other channel allocation techniques by allocating a channel in consideration of a mobile terminal's interference range dependent on the distance between a base station and the mobile terminal. A base station, if a channel allocation request is detected, checks whether unassigned channels exist(600,602). If unassigned channels exist, the base station selects one of the unassigned channels(604). On the assumption that the selected channel is allocated, the base station judges whether the selected channel has influence on mobile terminals which belong to neighbor base stations(606). In case it is judged that any of the mobile terminals which belong to neighbor base stations is not influenced by the selected channel, the base station allocates the selected channel(610). Then the base station transmits downlink channel allocation information to the neighbor base stations, including allocated channel information(612).

Abstract: A transmission device and a method using a multi-stage contention are provided to improve a production yield and equality with respect to the use of channels of each user. A contention window initializing and backoff counter setting unit(100) initializes a contention window value of each stage, and sets a random backoff counter value of each stage. A backoff counter subtracting unit(102) reduces a backoff counter value of a corresponding stage by slot time. A comparing unit(104) checks whether or not the reduced backoff counter value is 0, and whether or not the corresponding stage is a final contention stage, and outputs a backoff counter value 0 of the final contention stage to a data transmission unit(108). When the backoff counter value 0 of the final contention stage is received, the data transmission unit transmits data to a reception side.

Abstract: A method for scheduling resources in a wireless communication system is provided to allocate the resources to an MS in consideration of a data rate and a packet generation cycle which can be varied according to time, thereby minimizing a waste of the resources. A method for allocating resources to an MS(Mobile Station) in a wireless communication system comprises the following steps of: enabling the MS to determine whether the generation cycle of a packet to be transmitted is changed(802); notifying a BS(Base Station) of an increase of the packet generation cycle before transmitting an initial packet corresponding to the increased packet generation cycle(804); and receiving the resources in correspondence to the packet generation cycle increased from the BS(806).
