Abstract: A signal transceiving device for minimizing ICI(Inter Cell Interference) in a communication system and a method are provided to enable all base stations of the communication system to transmit common control information by using the same sub-carrier allocation pattern which is an M-PUSC method, thereby improving ICI elimination performance in accordance with repeated code MMSE(Minimum Mean Square Error) usage. When information to be transmitted is generated, a base station repeats the information as many as the preset number of times, and generates the information as repeated information. All base stations belonging to the communication system allocate sub carriers for transmitting the repeated information according to an equally used sub-carrier allocation scheme, respectively. The repeated information is transmitted by using the allocated sub carriers.

Abstract: A method and an apparatus of an automatic repeat request in a broadband wireless communication system supporting multi-hop are provided to prevent a buffer in an RS(Receiver Server) from being overflown by preventing a simple feedback between a BS(Base Station) and an MS(Mobile Station). A relay node receives data blocks from a source node and delivers the data blocks to a destination node. A first number, the smallest BSN(Block Sequence Number) of the data block delivered to the destination node, is compared with a second number, the smallest BSN fed back from the destination node(601). A third number, the biggest BSN fed back from the destination node to the relay node, is compared with a fourth number, the biggest BSN received from the source node(603). When the first and second numbers are matched and the third and fourth numbers are matched(607), an ARQ message to be transmitted to the source node is generated by using the smallest and biggest BSNs from the source node, and the ARQ(Automatic Repeat Request) message is transmitted(609).

Abstract: An apparatus and a method for receiving signals in a communication system are provided to improve signal reception performance by selecting whether to use an interference cancellation scheme, correspondingly to a modulation scheme. An apparatus for receiving signals in a communication system comprises a demodulator(213), a controller(227), a channel estimator(215), and a selector(217). The demodulator(213) receives information about the first modulation scheme, which a serving BS(Base Station) will apply to a frequency domain, from the serving BS, demodulates it. Afterwards, the demodulator(213) receives a signal through the frequency domain and demodulates the received signal. The controller(227) estimates a modulation scheme, which a neighbor BS will apply to the frequency domain, by using the received signal and determines the estimated modulation scheme as the second modulation scheme. The channel estimator(215) estimates the received signal and creates channel state information. The selector(217), based on the channel state information and the information about the first and second modulation schemes, selects whether to use an interference cancellation scheme.

Abstract: A method and a system for allocating resources in a communication system are provided to improve the performance of a system by dividing a data transmission domain into an interference domain and a non-interference domain so that an MS(Mobile Station), which suffers cell interference from a neighbor cell, can easily remove the cell interference and increase the CINR(Carrier to Interference Noise Ratio). A BS(Base Station), if its own cell ID is determined, segments a data transmission domain for transmitting data to MSs, which exist within its own cell, into an interference domain and a non-interference domain(501). Then, the BS receives feedback information from the MSs(503). Based on the received feedback information, the BS confirms locations of each MS(505). If it is confirmed that an MS is in the interference domain, the BS allocates interference domain resources to the MS(507). On the contrary, in case an MS is in the non-interference domain, the BS allocates non-interference domain resources to the MS(509). Then, after inserting the segmentation information of the data transmission domain and resource allocation information into a MAP message and sends it to each MS, the BS transmits data to each MS through the allocated resources.
