An apparatus and a method control interference via inter-base station information exchange in a communication system. In a method for operating a serving base station, for controlling interference in a communication system, sum of yield loss amounts of terminals inside a neighbor base station by a power level rise of the serving base station is determined. Yield gain amounts of serving terminals by the power level rise of the serving base station are determined. The sum of the yield loss amounts of the terminals inside the neighbor base station by the power level rise of the serving base station is compared with the determined yield gain amounts of the serving terminals by the power level rise of the serving base station, so that a power level for each serving terminal is determined.

An apparatus is capable of transmitting information via an uplink control channel in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system. Uplink control information is encoded to obtain a predetermined bit string. A signal sequence corresponding to the predetermined bit string is generated. The signal sequence is cyclic-shifted according to a predetermined rule. The cyclic-shifted signal sequence is controlled according to a subframe length. Therefore, reception performance deterioration of an uplink control channel allocated to an irregular subframe can be minimized.

Methods of transmitting an receiving symbols by a Mobile Subscriber Station (MSS) and a Base Station (BS) are provided. The method for receiving symbols by the MSS includes receiving symbols from the BS, wherein the symbols are mapped onto data sub-carriers using a sequence, wherein the sequence includes result values, the result values being generated by applying, to a basic sequence, an offset and a number of cyclic shifting, the basic sequence having a length identical to the number of data sub-carriers. The method for transmitting symbols by the MSS includes transmitting symbols to the BS, wherein the symbols are mapped onto data sub-carriers using a sequence, wherein the sequence includes result values, the result values being generated by applying, to a basic sequence, an offset and a number of cyclic shifting, the basic sequence having a length identical to the number of data sub-carriers.

An apparatus and method for supporting Quality of Service (QoS) in a wideband wireless communication system using multiple Frequency Allocations (FAs) are provided. In a transmitting method for packet distribution in the wideband wireless communication system, the method includes, during a network entry process, determining a number of FAs through multi-FA capability negotiation; distributing packets, received from a superordinate layer, through the multiple FAs; and transmitting the packets distributed through the multiple FAs. Accordingly, packets can be effectively distributed through multiple FAs, and QoS can be effectively provided.
