摘要： A mobile station supporting selective transmit diversity (STD) efficiently transmits forward channel status information to a base station in a 1xEV-DV mobile communication system. The mobile station receives signals transmitted from the base station through a plurality of transmission antennas, measures signal strengths of the received signals, compares the measured signal strengths after compensating for a transmission power difference between the transmission antennas, and selects a transmission antenna having the highest signal strength. The mobile station transmits forward channel status information indicating measured signal strength for a signal transmitted from the selected transmission antenna to the base station along with antenna selection information indicating the selected transmission antenna. The forward channel status information includes absolute status information representing measured signal strength for a transmission antenna selected at a current time interval, or relative status information representing a result obtained by comparing the measured signal strength for the transmission antenna selected at the current time interval with measured signal strength for a transmission antenna selected at a previous time interval.

摘要： Disclosed is a method for indicating an end of transmitting data frames in order to enable a UTRAN (UMTS (Universal Mobile Telecommunications System) Terrestrial Radio Access Network) to assign a common packet channel to another user equipment (UE) in a UE for a CDMA mobile communication system. The UE transmits at least one control frame, in an appointed field of which a given bit pattern appointed with the UTRAN is registered, in order to inform the UTRAN of an end of data transmission upon completing data transmission through the data frames.

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 one of two initial values separately determined for the two data sequences.

摘要： An apparatus and method for transmitting a signal in a communication system using a Hybrid Automatic Repeat reQuest (HARQ) scheme are provided. The method includes generating a codeword vector by encoding an information vector by using a first parity check matrix of Low Density Parity Check (LDPC) codes, generating a transmission vector by processing the codeword vector, and transmitting the transmission vector. When the first parity check matrix includes a plurality of square matrix columns, each square matrix includes a size of L × L , the first parity check matrix is one of p parity check matrixes stored in the signal transmission apparatus, the p parity check matrixes support different numbers of information vector square matrix columns, and each of the numbers of information vector square matrix columns indicates the number of square matrix columns corresponding to the information vector from among the plurality of square matrix columns. The first parity check matrix is a parity check matrix supporting the number of information vector square matrix columns determined by using the length of the information vector and the value L from the p parity check matrixes, and the value L is determined by using p and the length of the information vector.
