    摘要： Disclosed are a method and apparatus for measurement report for the decision of transmission mode transition that obtain a threshold value of reporting CQI_difference of all frequency sub-bands; measure a CQI value at each CQI reporting frequency sub-band of whole frequency band in each measure time interval; determine a CQI_difference value based on the measured CQI value of each CQI reporting frequency sub-band; and compare the determined CQI_difference value with the threshold value, if a condition is satisfied, then the UE sends the determined CQI_difference value to the BS. After the UE has reported this measurement report to the BS, the BS may choose a more suitable data transmission mode for the UE based on this measurement report to make data transmission more effective.

    摘要： A communication apparatus (CA) such as a mobile node/station (MN), a base station (BS), or a radio station (RS) may support determination of HARQ timing. The CA may generate at least in part one or more generalized frames such as a frequency division duplex (FDD) frame or a time division duplex (TDD) frame. The generalized FDD and TDD frames may include support to determine the HARQ timing considering various factors, which may affect the HARQ timing. The FDD and TDD frames may include information corresponding to various factors to determine the HARQ timing considering factors such as DL/UL ratio, number of sub-frames per frame, variable transmission time interval (TTI), relay zones, legacy IEEE® 802.16e zones, and availability of ACKCH.

    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. The present invention uses comparatively shorter bit sequence to indicate CQI report sub-bands needed to be reported and reduces the number of information bits necessary for CQI report sub-bands and also reduces the number of information bits corresponding to the CQI values in the CQI report sub-bands.
