For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
In the existing LTE system, a descending sub frame comprises 14 symbols, and the Downlink Control Information such as PDCCH information are positioned at a front n symbol, and wherein, n can be 1,2,3 or 4, and this zone can be called the control channel zone; The downlink data of this PDCCH scheduling is carried in 14 symbols of n+1 to the of back, control channel zone, and this zone can be called the data channel zone.
The schematic flow sheet of the control signal that Fig. 1 provides for one embodiment of the invention and the transmission method of downlink data, as shown in Figure 1, the control signal of present embodiment and the transmission method of downlink data can comprise:
101, the base station is that the subscriber equipment of dispatching produces control signal, and above-mentioned control signal is used to indicate the schedule information of upstream data and/or downlink data;
Wherein, above-mentioned control signal can be descending control signaling, perhaps can also be upstream control signaling, perhaps can also be descending control signaling and upstream control signaling.
102, above-mentioned base station sends above-mentioned control signal and downlink data by the above-mentioned subscriber equipment of at least one RB subtend, so that above-mentioned subscriber equipment, decodes above-mentioned downlink data according to above-mentioned control signal or sends upstream data to above-mentioned base station.
Wherein, resource multiplex is carried out in above-mentioned control signal and at least a portion downlink data data channel zone at least one RB.Particularly, above-mentioned control signal and above-mentioned at least a portion downlink data can the data channel zone in above-mentioned at least one RB carry out that space resources is multiplexing, frequency domain resource is multiplexing and in multiplexing at least one of time-domain resource.
Be understandable that: above-mentioned downlink data can be this user's of the control signal scheduling that produces of the subscriber equipment dispatched downlink data for base station in 101, can be other users' of dispatching of control signal that the subscriber equipment of other scheduling produces downlink data for the base station also.
For example: it is multiplexing that space resources is carried out in above-mentioned control signal and the data channel zone of above-mentioned at least a portion downlink data in above-mentioned at least one RB, be that above-mentioned control signal at least one pilot tone port in data channel zone in above-mentioned at least one RB transmits, above-mentioned at least a portion downlink data other pilot tone ports in data channel zone in above-mentioned at least one RB transmit.Wherein, can be in other ports part or all on other pilot tone ports, present embodiment does not limit this.As shown in Figure 2, it is multiplexing that space resources is carried out in descending control signaling and at least a portion downlink data data channel zone in RB1, and it is multiplexing that space resources is carried out in upstream control signaling and at least a portion downlink data data channel zone in RB2.Wherein, pilot tone port x 1～pilot tone port x N1 transmission in descending control signaling data channel zone in RB1 is that the transmission number of plies of descending control signaling is N1, pilot tone port x 1～pilot tone port x N2 transmission in upstream control signaling data channel zone in RB2 is that the uplink control signaling transmission number of plies is N2, the pilot tone port Y1 in data channel zone～pilot tone port YM2 transmits among the pilot tone port Y1 at least a portion downlink data data channel zone in RB1～pilot tone port YM1 and the RB2, wherein, N1+M1=N2+M2; Another part data all pilot tone ports in data channel zone in RB3 and RB4 transmit, and this part data transfer number of plies is N1+M1 (being N2+M2).As shown in Figure 3, it is multiplexing that descending control signaling (uplink scheduling signaling) and at least a portion downlink data carry out space resources in the data channel zone of RB in to 1.Wherein, descending control signaling (uplink scheduling signaling) RB to 1 in the pilot tone port x 1～pilot tone port x N transmission in data channel zone be that the transmission number of plies of descending control signaling (uplink scheduling signaling) is N, at least a portion downlink data RB to 1 in the pilot tone port Y1～pilot tone port YM in data channel zone transmit; Another part data RB to 2 in all pilot tone ports in data channel zone transmit, this part data transfer number of plies is N+M.
Again for example: above-mentioned control signal and the data channel zone of above-mentioned at least a portion downlink data in above-mentioned at least one RB carry out time domain or frequency domain resource multiplexing, namely different time or the frequency of above-mentioned control signal and above-mentioned at least a portion downlink data at least one pilot tone port in data channel zone in above-mentioned at least one RB are transmitted.As shown in Figure 4, it is multiplexing that frequency domain resource is carried out in descending control signaling and at least a portion downlink data data channel zone in RB1, and it is multiplexing that frequency domain resource is carried out in upstream control signaling and at least a portion downlink data data channel zone in RB2.Wherein, frequency f 1～frequency f u1 transmission of descending control signaling pilot tone port x 1～pilot tone port x N1, pilot tone port Y1～pilot tone port YM1 in data channel zone in RB1 is that the transmission number of plies of descending control signaling is N1+M1, and frequency f 1～frequency f u2 transmission of upstream control signaling pilot tone port x 1～pilot tone port x N2, pilot tone port Y1～pilot tone port YM2 in data channel zone in RB2 is that the uplink control signaling transmission number of plies is N2+M2; The frequency f u2 of pilot tone port x 1～pilot tone port x N2, the pilot tone port Y1～pilot tone port YM2 in data channel zone～frequency f v2 transmits among the frequency f u1 of at least a portion downlink data pilot tone port x 1～pilot tone port x N1, pilot tone port Y1～pilot tone port YM1 in data channel zone in RB1～frequency f v1 and the RB2; Another part data all pilot tone ports in data channel zone in RB3 and RB4 transmit, and this part data transfer number of plies is N1+M1 (being N2+M2).
