摘要： The present invention relates a method and apparatus for transmitting/receiving data using multiple codewords in a communication system using SC-FDMA (single carrier frequency division multiple access). A transmitter generates the multiple codewords for user data and transmits the generated multiple codewords. A receiver receives the multiple codewords and sequentially performs decoding and SIC (successive interference cancellation) on the received multiple codewords. Therefore, this structure can minimize a PAPR (peak to average power ratio) and considerably reduces interference between symbols in a frequency selective fading environment.

摘要： Disclosed is a method for transmitting and receiving control information. The method for transmitting control information according to the present invention, in a mobile communication system in which a control channel region and a data channel region are separated from each other, comprises the steps of: determining a control channel resource for transmitting control information by means of the data channel region; and transmitting the control information using the determined control channel resource. According to the present invention, a capacity for control information, which increases for multiple user multiple-input multiple-out (MIMOs) in a heterogeneous network environment, for heterogeneous network interference control using carrier aggregation, for frequent use of a multicast-broadcast single frequency network (MBSFN) subframe, and for a CoMP transmission control, may be satisfied. Further, an adaptive resource allocation based on a requested capacity for control information may be enabled, and the efficient utilization of resources may also be enabled.

摘要： The present invention relates to a method and apparatus for constructing a control channel and transceiving data in a wireless communication system. User equipment monitors physical downlink control channel (PDCCH) candidates which are CRC-scrambled by a cell-radio network temporary identifier in a common search space and in a user equipment-specific search space. The user equipment regards that only the desired PDCCH is transmitted in the common search space if the PDCCH candidates have a common payload size and same index of first control channel elements, thus overcoming problems of ambiguity in detection of DCI.

The method includes: in a receiving block, decoding packets received from a transmitting block and detecting whether an error exists or not in the packets; if the error is detected, transmitting a negative acknowledgement (NACK) signal informing transmission failure of the packets to the transmitting block; calculating channel quality information (CQI) values for transmission-failed packets after performing successive interference cancellation (SIC) with respect to all antenna combinations to retransmit the transmission-failed packets; and selecting an antenna combination having CQI values of the transmission-failed packets which are equal to or greater than respective initial CQI values of the transmission-failed packets among the antenna combinations, and transmitting information of the selected antenna combination to the transmitting block.
