In LTE TDD mode, identical working frequency range is adopted in up-downgoing, and up-downgoing TTI is cross occurrence in a subframe.Fig. 2 shows a kind of situation of the structure of time slot in the frame.As shown in Figure 2; a radio frames comprises two subframes; each subframe comprises time slot (Time Slot; TS) 0 to time slot 6 these 7 common time slots and descending pilot frequency time slot (Downlink Pilot Time Slot; DwPTS), protection (GP) and uplink pilot time slot (Uplink Pilot Time Slot, UpPTS) such special time slot at interval.Wherein, a common time slot is a TTI.In the structure of time slot example shown in Figure 2, descending time slot is after ascending time slot inversion point (DUSP) is positioned at DwPTS, and ascending time slot is after descending time slot inversion point (DUSP) is positioned at TS3, and like this, TS0 is descending, and TS1～TS3 is up, and TS4～TS6 is descending.
Among the existing LTE TDD, control channel is disposed in the descending time slot in the subframe, and this control channel control range comprises this time slot and 6 common time slots that comprise the next son frame slot of order thereafter.For example control channel is positioned at TS0 among Fig. 2, and this control channel is dispatched the time slot in the TS0 in this subframe～TS6 scope; When control channel is positioned at TS4, this control channel is dispatched the time slot in the TS4 in this subframe～TS6 scope, and the time slot in the TS0 in next subframe～TS3 scope is dispatched.
By the control signaling in the control channel resource in 7 time slots is dispatched.Which time slot in 7 time slots of the concrete scheduling of control channel and the control information in the control channel need be sent to terminal during each the scheduling, wherein, the time slot of control channel scheduling is by introducing the indicating mechanism realization in dispatch.A kind of indicating mechanism is the mode that adopts bitmap, this mode can be as shown in Figure 3,7 bits in the bitmap territory are 7 interior time slots of corresponding control range respectively, indicate respectively on 7 bits and whether pairing time slot is controlled, can adopt 1 expression to dispatch, 0 expression is not dispatched.In Fig. 3, if control channel is positioned at TS0, then this bitmap represents TS0, TS1 and TS3 are dispatched.Among the existing LTE TDD, when sending control signaling, need in the subframe of control channel place, comprise the corresponding relation of the control channel and the time slot of controlling, i.e. bitmap figure.This bitmap sends to terminal as the control signaling.
But, the bitmap mechanism of introducing in the existing method, the base station is when each scheduling, bitmap need be sent to terminal as a part of controlling signaling, and bitmap takies part control signaling consumption, therefore, can cause controlling the increase of signaling consumption, promptly Radio Resource produced too much consumption.
