摘要： Disclosed is an apparatus and method for transmitting/receiving a control message in a wireless communication system that is designed to reduce overhead associated with transmission/reception of the control message. To this end, a transmission apparatus generates a control message, generates a compressed control message by compressing the generated control message, based on a control message that has been lastly received by a reception apparatus from among previously transmitted control messages, selects one of the generated control message and the generated compressed control message according to whether or not the control message lastly received by the reception apparatus exists, and transmits the selected one of the generated control message and the generated compressed control message to the reception apparatus. Therefore, it is possible to reduce resources used for control message transmission, and thus increase the use efficiency of the resources.

摘要： Disclosed is an apparatus for performing power control on a reverse channel quality indicator channel (CQICH) received from a mobile station by a base station in a mobile communication system including the base station for transmitting a power control bit for power control on reverse channels and the mobile station for controlling transmission power of the reverse channels according to the power control bit. An erasure detector determines whether to perform an erasure process by measuring reception power of the reverse channel quality indicator channel. An erasure rate calculator accumulates the erasure-determined result for N slots and calculates an erasure rate for the N slots. A control bit generator determines a ratio control bit to be transmitted to the mobile station according to the erasure rate, to issue a command to increase or decrease a CQICH traffic-to-pilot ratio.

摘要： An apparatus and method for efficiently distributing energy to a packet data channel. A turbo encoder generates a sequence of systematic symbols and a sequence of parity symbols by encoding an information bit stream. An interleaver interleaves the systematic symbol sequence and the parity symbol sequence, separately and serially concatenates the interleaved systematic symbol sequence and the interleaved parity symbol sequence. An energy distributor rearranges the concatenated symbols so that the systematic symbols are disposed in a high energy-having portion of a predetermined transmission period when transmission energy varies for the transmission period. A modulator modulates the rearranged symbols.

摘要： Disclosed is an apparatus for generating an error detection information bit sequence for determining a length of data sequence transmitted in a communication system. The apparatus comprises a plurality of cascaded registers, the number of which is identical to the number of bits in the error detection information bit sequence, and a plurality of adders arranged on paths determined by a predetermined generator polynomial, each of the adders adding a bit sequence received through an input path to a feedback bit sequence. During reception of the control information sequence, an operator generates the feedback bit sequence by sequentially adding bits of the control information sequence to output bits of a final register and provides the generated feedback bit sequence to the adders. After completion of receiving the control information sequence, the operator sequentially adds a preset input bit to output bits of the final register and outputs the addition result as the error detection information bit sequence. An initial value controller provides the registers with a selected initial value separately determined for the data sequences.
