摘要： Provided is a method for transitioning between a distributed transmission mode and a localized transmission mode, including transmitting, by a Base Station (BS), a measurement control message to a User Element (UE), wherein the UE makes corresponding measurement and transmits a required measurement report message to the BS and the BS transmits a transition indicator message of new mode to the UE based on measurement report message sent from the UE; and commencing CQI reporting and a downlink transmission of a new mode between the UE and the BS. The BS can choose a more appropriate transmission mode for the downlink transmission based on changing characteristics of the channel in the time domain and the frequency domain.

摘要： A method for a UE reporting a CQI comprising steps of: obtaining a total number M of CQI report sub-bands in a system and a number N of CQI report sub-bands needed to be reported; measuring channel qualities of all sub-bands and according to the measurement result, determining N CQI report sub-bands needed to be reported and corresponding CQI values; sending a L-bit long sequence to a base station for indicating the sub-bands that need to be reported; sending CQI values corresponding to the sub-bands need to be reported to the base station.

摘要： The present invention describes that the C-RNTIs are grouped based on the random access preamble sequence, the transmission sub-frame and the transmission random access channel information used for the user equipment and detected by the base station. In such a way, the indicating information bits needed by C-RNTI allocation are decreased and the signaling overhead needed by C-RNTI allocation is also decreased. In addition, the random access process is optimized and the random access performance is improved.

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： Methods and apparatus are provided for transmitting control information in an SC-FDMA system. A UE generates a random cyclic shift value based on an SC-FDMA symbol index and a slot index. The UE cyclically shifts a sequence by the random cyclic shift value. The UE multiplies a control channel signal, including the control information, by the cyclically shifted sequence on an SC-FDMA symbol basis. The UE transmits the multiplied control channel signal in an SC-FDMA symbol to a Node B.
