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: 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).

Abstract: A data transmission system in a communication system and a method thereof are provided to optimally use resources and maximize the throughput by adaptively using band AMC(Adaptive Modulation and Coding) and diversity at the same time. A mobile station receives MAP information from a base station and confirms it(601). At this moment, the mobile station confirms its own present state and judges whether it is using band AMC or diversity. In case it is judged that band AMC is being used(603), the mobile station transmits packets using its own MAP information(603,605). If it is judged that diversity is being used(607), however, the mobile station grasps information about unused bands(609). Then the mobile station confirms the number of unused bands through the grasped information or a band AMC information MAP and grasps a diversity pattern to be used, based on the confirmed number(611). Then the mobile station transmits packets according to the diversity pattern using its own MAP information(613).

Abstract: An apparatus and a method for transmitting/receiving signals in a communication system are provided to prevent a waste of UL(Uplink)/DL(Downlink) resources by using a QDCCH(Quasi Dedicated Control CHannel) as a UL resource for providing a specific service, such as an rtPS(realtime Polling Service), etc., so that UL/DL resources can be allocated according to characteristics of burst data. A base station in an IEEE 802.16e communication system comprises a controller(715) and a sub-channel allocator(713). The controller(715) executes a control operation so that a QDCCH can be allocated to the first mobile station. Also, the controller(715) executes a control operation so that the QDCCH allocated to the first mobile station can be allocated to the second mobile station only during a preset time. The sub-channel allocator(713) allocates the QDCCH to the first mobile station or the second mobile station according to control of the controller(715).

Abstract: A device for improving link performance of a multicast service in a wireless system and a method therefor are provided to increase a receiving opportunity of retransmission packets of cell border users as using the same amount of radio resources, thereby improving link level performance of the multicast service of the users. If multicast data is received on the Nth frame, the data is restored by using systematic packets of the data(501). If the restoration of the data fails, parity packets of the data are received on the N+1th frame, and the data is restored by using the received parity packets(503,505). If the restoration of the data fails, autonomous handover is performed to receive the parity packets of the data from neighboring cells or sectors, and the data is restored by using the received parity packets(507,509).
