In order to achieve the object of the present invention, the embodiment of the invention provides a kind of transmissions of Downlink Control Information, recipient Method and equipment send Downlink Control Information DCI by base station equipment on the PDCCH of a downlink subframe, and the DCI instruction is used Family equipment UE is received on the downlink subframe for the first PDSCH information of this carrier wave scheduling and under at least one other The 2nd PDSCH information for being used for cross-carrier scheduling is received in row subframe;The base station equipment is sent out on the downlink subframe respectively It send the first PDSCH information and sends the 2nd PDSCH information on other described downlink subframes.In this way, base station is set The standby downlink control that carrier resource is realized in such a way that the scheduling of this carrier wave is combined with cross-carrier scheduling, so that user equipment exists After receiving the DCI sent on a PDCCH, it can quickly determine that the carrier resource for cross-carrier scheduling is carried PDCCH, and then the number of blind Detecting is effectively reduced, interference brought by blind Detecting is reduced, the tune of downlink control resource is promoted Spend efficiency.

The each embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.Obviously, described Embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field Those of ordinary skill's all other embodiment obtained without making creative work, belongs to protection of the present invention Range.

Fig. 1 is a kind of flow diagram of the inventive method of Downlink Control Information provided in an embodiment of the present invention.The side Method can be as follows.

Step 101: base station equipment sends DCI on the PDCCH of a downlink subframe.

Wherein, the DCI instruction user equipment (English: User Equipment;Abbreviation: UE) on the downlink subframe Receive the first Physical Downlink Shared Channel (English: Physical Downlink Shared for the scheduling of this carrier wave Channel;Abbreviation: PDSCH) information and at least one other downlink subframe receive be used for cross-carrier scheduling second PDSCH information.

In a step 101, in LTE system, in each transmission time interval (English: Transmission Time Interval;Abbreviation: TTI) in, UE passes through blind Detecting Physical Downlink Control Channel (English: Physical Downlink Control Channel;Abbreviation: PDCCH) or enhanced Physical Downlink Control Channel (English: enhanced Physical Downlink Control Channel;Abbreviation: ePDCCH), obtain Downlink Control Information (English: Downlink Control Information;Abbreviation: DCI).

It wherein, include the scheduling authorization information of down dispatch information and sub-frame of uplink in the DCI.

In addition, PDCCH is Physical Downlink Control Channel, the control domain part of the time-domain resource in a subframe, i.e., Top n OFDM (the Orthogonal Frequency Division in a subframe is occupied in time-domain resource Multiplexing orthogonal frequency division multiplexing) symbol, and by Physical Control Format Indicator Channel (English: Physical Control Format Indication Channel;Abbreviation: PCFICH) instruction PDCCH channel occupancy top n OFDM symbol.

It should be noted that N, which is greater than 0, is less than or equal to 3, usually when system bandwidth is 1.4M, N value is 4.

EPDCCH occupies entire subframe, and one or more resource block (English: Resource are occupied in frequency domain resource Block;Abbreviation: RB).

In an embodiment of the present invention, physical downlink control channel PDCCH is a general designation, including this is located at a subframe The PDCCH and/or the ePDCCH of interior top n OFDM.

In order to solve the problems, such as that number of carrier wave increase causes UE blind Detecting number to increase, the embodiment of the present invention proposes joint The scheduling of the mode of scheduling, i.e. this carrier wave is combined with cross-carrier scheduling, it is meant that, base station equipment is that the carrier resource of UE configuration is held Be loaded on different PDCCH, base station equipment pass through this carrier resource where PDCCH send DCI, instruction UE can dispatch across Carrier resource, reduces UE, and blind Detecting number effectively improves the dispatching efficiency of carrier resource.

As shown in Fig. 2 (a), for the schematic diagram of this carrier wave scheduling;It is the schematic diagram of cross-carrier scheduling as shown in Fig. 2 (b).

Preferably, before base station equipment sends DCI on the PDCCH of a downlink subframe, the method also includes:

Base station equipment is that UE configures at least two carrier resources, and determines the PDCCH for carrying each carrier resource, Wherein, the PDCCH of at least two carrier resources carrying is different.

Specifically, it is assumed that base station equipment is that UE configures 32 carrier resources, and base station equipment can be according to specified in agreement This 32 carrier resources are grouped by carrier wave polymerization grade, it is assumed that this 32 carrier resources are divided into 4 groups of carrier resource collection It closes, includes 8 carrier resources in each group of carrier resource set;Or assume this 32 carrier resources being divided into 8 groups of carrier waves Resource collection includes 4 carrier resources in each group of carrier resource set.Here it is illustrated for being divided into 8 groups.

Base station determines the PDCCH of each group of carrier resource set of carrying after being grouped 32 carrier resources.I.e. one PDCCH is upper can to carry multiple carrier resources.

In this way, base station equipment sends DCI on the PDCCH of a downlink subframe, comprising:
