摘要： An interference avoiding method in a wireless mobile communication system is provided to enable an MS(Mobile Station) to measure a signal strength ratio between a serving BS(Base Station) and a neighboring BS and to select preferred resource bands for minimizing inter-cell interference, thus the MS is able to be allocated with resource bands for minimizing interference signal reception. An MS measures the strength of signals received from a serving BS and neighboring BSs(301). The MS operates a ratio of the signal strength between the serving BS and the neighboring BSs(303). The MS compares the operated signal strength ratio with a preset reference strength value(305). The MS determines preferred resource bands capable of minimizing interference signal reception according to the compared results(307). The MS reports index information on the determined bands to the serving BS(309).

摘要： An apparatus and a method for canceling multi user interference in a communication system using an orthogonal frequency division multiple access scheme are provided to improve the performance of the system by removing the multi user interference at an upper link signal. In an apparatus for canceling multi user interference in a communication system using an orthogonal frequency division multiple access scheme, a station receiving stage receives an uplink signal through a receiving antenna. The uplink signal has signals from several moving stations. The received signal is inputted into an RF(Radio Frequency) processor(102). The RF processor(102) converts the received signal into a base band signal, and outputs the converted signal to an AD converter(104). The AD converter(104) converts the analog signal into a digital signal, and outputs the digital signal to a synchronizer(106). The synchronizer(106) estimates a time offset of the digital signal to acquire time synchronization, and outputs the time synchronization to a CP(Cyclic Prefix) remover(108). The CP remover(108) removes a CP from the digital signal, and outputs the signal to subtracters(130,140).

摘要： A resource operation method based on power control in a wireless mobile communication system is provided to allocate priority frequency bands to an MS(Mobile Station) which needs real-time services or has a weak channel, while general frequency bands are allocated to an MS which needs non real-time services or whose channel state is good, thereby satisfying minimum data transmission rates as magnifying system capacity. A control station sets initial power values of MSs to '0'(202), and conducts a power value updating process(204). The control station decides whether a power value necessary for uplink changing an MCS(Modulation and Coding Scheme) level is larger than a maximum power value usable by the MSs(206). If not, the control station up-converts an MCS level of an MS having a small requested power value(208). If an interference amount exerted to an MS using a priority frequency band by an MS using a general frequency band is less than a correlation amount of interference which the MS using the general frequency band is to be exerted(210), a final power value is determined(212).

摘要： A method and a system for allocating resources in a communication system are provided to improve the performance of a communication system by minimizing the occurrence of an interference signal in transmitting and receiving a signal through a multi-hop relay path. A scheduler of a BS(Base Station) determines an amount of resources to be allocated to every RS(Relay Station) existed in a cell(201). The scheduler determines whether the power of sub-channels available for each RS is a fixed value(203). If the power of sub-channels is a fixed value, the scheduler allocates sub-channels that are not repeated with respect to RSs to every RS(205). If different sub-channels which can be allocated without being repeated for the adjacent RSs are not sufficient, the scheduler determines an index of the sub-channels to be allocated so that the number of repeated sub-channels is minimal and allocates the sub-channels(207).

摘要： An apparatus and a method for controlling downlink power of a relay station in a broadband wireless access communication system are provided to reduce a load of transmission and reception of control signals in an overall system by fairly controlling transmission power of relay stations through information collected from the multiple relay stations. A relay station average downlink gain calculating unit(407) calculates a channel gain between a relay station(430) and a user terminal(440) based on a channel gain transmitted by the user terminal(440) under the relay station(430). An inter-relay station interference level detector(406) detects an interference level between the relay station(430) and an adjacent relay station. The information outputted by the relay station average downlink gain calculating unit(407) and the inter-relay station interference level detector(407) are transmitted to a base station(420). A transmission power control instruction, which has been calculated based on the received information by the base station(420) and then transmitted from the base station(420), is received to control the transmission power of the relay station(430).
