  • Method and apparatus for measurement report for the decision of transmission mode transition
    Patent number: 8243835
    Abstract: 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.
