A user equipment, method, and chipset use a first formula to determine a paging frame which is a radio frame including a paging occasion for the user equipment after the user equipment is configured with an idle mode extended DRX (Discontinuous Reception) cycle, a second formula to determine a subframe from among the paging frame, as the paging occasion, and a third formula to determine a paging hyper-frame. DRX parameters are applied to the first formula and the second formula, but not to the third formula. An idle mode extended DRX cycle is applied to the third formula, which is represented by H-SFN mod TeDRX=α mod TeDRX, where the H-SFN represents a hyper-frame number of the paging hyper-frame, the TeDRX represents the number of the hyper-frames corresponding to the idle mode extended DRX cycle, and the α represents a value specific to the user equipment.
