Abstract:
1. A method for creating a measurement report for decision of transmission mode transition, the method comprising steps of: obtaining by a User Equipment (UE) a threshold value of reporting a Channel Quality Indicator (CQI) difference) of all frequency sub-bands; the UE measuring a CQI value in each CQI reporting frequency sub-band of an entire frequency band at each measured time interval; the UE calculating moving average CQI values by performing time domain moving average filtering for the measured CQI values of each CQI reporting frequency sub-band; the UE determining a CQI_difference value based on a maximum value and a minimum value among the calculated moving average CQI values; and the UE comparing the determined CQI_difference with the threshold value, if a condition is satisfied, the UE sending the determined CQI_difference as the measurement report to a base station.
