Abstract:
PROBLEM TO BE SOLVED: To provide a radio communication system capable of suppressing a delay until data are transmitted to a base station apparatus after the data are stored in a buffer of an apparatus on a user side.SOLUTION: A base station apparatus 20 manages an amount of transmission waiting data for each of pieces of user equipment (hereinafter referred to as UE) 10 existing in a cell area 30 and, to UE 10 having an amount of transmission waiting data equal to or smaller than a predetermined report threshold, transmits a recognized residual amount report indicating an amount recognized as an amount of transmission waiting data of the UE 10. When the recognized residual amount report from the base station apparatus 20 is received, the UE 10 determines, on the basis of the recognized residual amount report, whether or not an amount of transmission waiting data recognized by the base station apparatus 20 (hereinafter referred to as a recognized residual amount) matches an actual amount of transmission waiting data (hereinafter referred to as an actual residual amount). When the recognized residual amount is smaller than the actual residual amount, the UE sequentially transmits an SR and a BSR to acquire transmission opportunity corresponding to the actual residual amount.SELECTED DRAWING: Figure 1
