摘要： A data transmission method for the detection of control information is provided to shorten a time for detecting data and minimize the power consumption by enabling each UE(User Equipment) to speedily and efficiently detect its own control from downlink data. In transmitting downlink user data to a plurality of UEs, a base station prepares control information which is associated with each UE's user data. The base station transmits location information for each control information. The base station multiplexes the control information. Then the base station transmits the multiplexed control information. In this case, the location information and the control information are transmitted through different channels or an identical channel. The location information indicates each UE's MCS(Modulation and Coding Scheme) level or MIMO(Multiple Input Multiple Output) mode.

摘要： A retransmission method using an LDPC(Low Density Parity Check) code is provided to satisfy dense characteristics by using a split method for splitting a column in a high code rate. A retransmission method using an LDPC includes a first encoding process, a parity bit transmission process, and a part transmission process. The first encoding process is performed to encode transmission data to be transmitted to a receiving terminal by using a parity check matrix formed with a plurality of rows split from one row. The parity bit transmission process is performed to transmit party bits selected from the parity bits generated through the first encoding process, and the parity bit. The part transmission process is performed to transmit a part of the residual parity bits except for the selected parity bits when a NACK signal is received from the receiving terminal.

摘要： An SNR(Signal to Noise Ratio) estimating method, an adaptive modulation/coding scheme determining method, and a receiver are provided to determine an optimal MCS(Modulation and Coding Scheme) level by decreasing an estimation error due to a time delay in a mobile channel environment. A channel encoder(110) receives a stream of information bits, encodes the information bits under the control of an AMC(Adaptive Modulation Coding) controller, and forms coded data. A symbol mapper(120) modulates the coded data according to a modulation scheme under the control of the AMC controller, and provides modulation symbols. An IFFT(Inverse Fast Fourier Transform) unit(130) converts input symbols into time domain samples. A CP(Cyclic Prefix) inserter(140) inserts a CP to time domain samples. A receiver circuit(180) receives signals from a receiver through an antenna, digitizes the received signals, and transmits the digital signal to the AMC controller. The AMC controller(160) controls a transmitter.
