摘要： A radio communication system divides an entire frequency band into a plurality of subcarrier bands, forms a symbol with signals on the subcarrier bands, forms a frame with a plurality of symbols, transmits a pilot signal within symbols in a predetermined position of the frame, and transmits a data signal within symbols other than the symbols for transmitting the pilot signal. A transmitter allocates subcarriers through which the reference signal is transmitted, wherein the subcarriers are allocated to have an exclusive relation with subcarriers through which reference signals of other transmitters are transmitted, generates the pilot signal, performs an inverse fast Fourier transform (IFFT) on the pilot signal by applying an IFFT size which is less than or equal to an IFFT size applied to the data signal, and transmits the IFFT-processed reference signal to a receiver.

摘要： A channel coding device is disclosed. In the device, a bit inserter inserts known bits in an input data bit stream at predetermined positions. A channel coder codes the bit-inserted data bit stream to generate coded symbols. A rate matcher matches a rate of the coded symbols to a given channel symbol rate. A channel interleaver interleaves the rate matched channel symbols. The rate matcher includes a puncturer for puncturing the inserted known bits included in the coded symbols when the coded symbol rate is higher than the given channel symbol rate. The rate matcher includes a repeater for repeating the coded symbols to match the coded symbol rate to the given channel symbol rate when the coded symbol rate is lower than the given channel symbol rate.

摘要： A method of adjusting the transmission time of data in a CDMA communication system. A UE (User Equipment) measures the time difference between the received time of a downlink DPCH (Dedicated Physical Channel) and the transmitted time of an uplink DPCH and reports it to an RNC (Radio Network Controller). The RNC transmits transmission time adjustment information to a node B and the UE if the time difference is out of a predetermined range. The node B then adjusts the transmission time of the downlink DPCH according to the transmission time adjustment information and transmits the downlink DPCH at the adjusted time. The UE receives the downlink DPCH by adjusting a search time for the downlink DPCH according to the transmission time adjustment information.

摘要： A mobile communication apparatus having an antenna array and a mobile communication method performed in the mobile communication apparatus, wherein the mobile communication apparatus includes a base station and mobile station, each having an antenna array. The mobile station measures the downlink characteristics of a channel for each antenna from a signal received from a base station, determines long-term information in which the correlation property of the channel for each antenna has been reflected from the measured downlink characteristics, transforms the long-term information into a feedback signal, and transmits the feedback signal to the base station. The base station receives the feedback signal, restores the long-term information from the received feedback signal, performs basis mapping and basis transformation on a dedicated physical channel signal using the restored long-term information, adds the basis-mapped and basis-transformed signal to each of pilot channel signals, and transmits the addition results to the mobile station.

摘要： A method for HARQ reordering in Enhanced Uplink Dedicated Channel of WCDMA system includes following steps: locating the soft combination buffer in the Node B and the reordering buffer in the SRNC; locating the HARQ entity in the Node B; locating the reordering queue distribution entity, the reordering entity and the disassembly entity in the SRNC. This invention adopts the separation technology of the soft combination buffer and the reordering buffer, the separation model can not only ensure the diversity gain, but also reduce the receiving delay and save the buffer space. Three mechanisms (timer mechanism, window mechanism and SBI mechanism) are proposed to prevent the blocking of the reordering buffer, which degrades the blocking to the least level, improves the receiving efficiency and the system performance. Aiming at the SBI mechanism, the invention proposes the new DCH data frame structure on the Iub interface and the Iur interface.

摘要： An apparatus and method for reducing a Peak to Average Power Ratio (PAPR) in a broadband wireless communication system. A transmitter classifies symbols into full-symbols and sub-symbols, and divides a transmission full-symbol into at least two sub-symbols and transmits the sub-symbols, when the transmission full-symbol has a PAPR larger than a threshold set in the system. A receiver checks a transmitted symbol, determines if a full-symbol or a sub-symbol has arrived, and outputs a data when the full-symbol has arrived.
