Wherein, the schedule information that in a DCI information, descending sub frame is corresponding only is used for descending sub frame n is dispatched.

Better, network equipment 10 can also send data according to the schedule information in a DCI information after sending a DCI information and the 2nd DCI information in descending sub frame n; And according to the schedule information except the corresponding schedule information of descending sub frame in a DCI information and according to the corresponding schedule information of descending sub frame in the 2nd DCI information, send data on the descending sub frame that is scheduled in N continuous descending sub frame.

Accordingly, terminal 20 receives the downlink data of PDSCH (Physical Downlink Shared Channel, physical down link sharing channel) carrying in the descending sub frame n that is scheduled according to a DCI information; And according to the schedule information except the corresponding schedule information of descending sub frame in a DCI information, and the corresponding schedule information of descending sub frame in the 2nd DCI information, receive the downlink data on the descending sub frame that is scheduled in N continuous descending sub frame.

Wherein, the 2nd DCI information comprises: the corresponding schedule information of descending sub frame that is scheduled in the individual descending sub frame continuously of N, N is positive integer, and N＜N _Process, N _ProcessIt is the maximum process number of descending HARQ.

N is not more than N due to restriction _ProcessThereby assurance network equipment 10 can once not dispatched the repeatedly transmission of same process.After avoiding error of transmission, when carrying out the HARQ re-transmission, terminal 20 can't determine that network equipment 10 is the re-transmissions which data block of the same process numbering of correspondence is carried out.

Better, network equipment 10 can use C-RNTI to carry out scrambling when the DCI information of transmission.

Better, network equipment 10 is determined the bit number that the 2nd DCI information takies, and the transmission information of each descending sub frame of dispatching as required, need in the 2nd DCI information to determine respectively the schedule information corresponding to each descending sub frame of dispatching, bit number and the 2nd schedule information corresponding to DCI information according to the 2nd DCI information of determining takies generate the 2nd DCI information.

It is a variety of that the network equipment 10 of the embodiment of the present invention determines that the mode of the 2nd DCI information has, and the below enumerates several.

Mode one, definition a kind of special RNTI (being designated as MS-RNTI) are used for carrying out the multiframe scheduling.MS-RNTI is that terminal 20 is exclusive, i.e. different terminal 20, and MS-RNTI is not identical yet.

Concrete, the concrete condition of a plurality of descending sub frames that network equipment 10 is dispatched as required configures respectively the corresponding schedule information of each subframe, such as the HARQ process number, new data indication information and redundancy version information, and adopt MS-RNTI to carry out scrambling to the 2nd DCI information.

Accordingly, terminal 20 just knows it is an own corresponding DCI information in the DCI information of blind check to the C-RNTI scrambling of self correspondence; In the DCI information of blind check to the MS-RNTI scrambling of self correspondence, just know it is own the 2nd corresponding DCI information.

Better, when determining the bit number that the 2nd DCI information takies, the bit number that the bit number that network equipment 10 can take DCI form 1A takies as the 2nd DCI information.

Network equipment 10 can also be from current configuration to selecting a DCI form the uplink transmission mode of terminal 20 and/or DCI form corresponding to downlink transfer pattern, and the bit number that takies as the 2nd DCI information of the bit number that the DCI form of selecting is taken.

The uplink transmission mode here and/or downlink transfer pattern have three kinds of situations: 1, only have uplink transmission mode; 2, only has the downlink transfer pattern; 3, uplink transmission mode and downlink transfer pattern are arranged.

If only have the downlink transfer pattern, network equipment 10 from current configuration to selecting a DCI form DCI form corresponding to the downlink transfer pattern of terminal 20.When being configured to downlink transfer pattern 1 such as terminal 20, the bit number that the 2nd DCI information takies can equal the bit number that bit number that DCI form 1A takies or DCI form 1 take.

If uplink transmission mode and downlink transfer pattern are arranged, network equipment 10 from current configuration to selecting a DCI form DCI form corresponding to any available transmission pattern of terminal 20.When being configured to downlink transfer pattern 1 and uplink transmission mode 2 such as terminal 20, the bit number that the 2nd DCI information takies can equal the bit number that bit number that DCI form 1A takies, bit number that DCI form 1 takies or DCI format 4 take.

Better, the bit number that the 2nd DCI information takies is except satisfying above-mentioned requirements, can also completely need be by following requirement: L _DCI2〉=NL+L _CIF+ L _ARI

Wherein, L _DCI2Be the bit number that the 2nd DCI information takies, L is the bit length that the corresponding schedule information of descending sub frame takies, L _CIFThe bit number that CIF (Carrier Indicator Field, carrier wave is indicated the territory) takies, L _ARIIt is the bit number that ARI (ACK NACK Resource Indicator, feedback resources indication) territory takies.

If 10 of network equipments are determined the 2nd a DCI information, the descending sub frame after dispatching downlink subframe n is the part or all of subframe in N continuous.

Better, network equipment 10 can send the 2nd DCI information in needs, and in each subframe, the quantity of the 2nd DCI information of corresponding same carrier wave is not more than 1; Accordingly, terminal 20 receives corresponding downlink data according to the 2nd DCI information that receives at last.

Better, mode two, whether network equipment 10 can also carry out the multiframe scheduling by high-level signaling configurating terminal 20.

Better, network equipment 10 can be according to the order of subframe numbers, and the schedule information that descending sub frame is corresponding is placed in the 2nd DCI information.Such as arranging as follows: the schedule information that descending sub frame n+1 is corresponding, descending sub frame n+2 is right answers schedule information ..., the schedule information that descending sub frame n+N is corresponding.

Need to prove, the embodiment of the present invention is not limited to said sequence, and other orders are the applicable embodiment of the present invention too, such as from back to front; Even number subframe after first odd number subframe.But need to guarantee that terminal 20 is identical with the order that network equipment 10 adopts.

Certainly, for the TDD system, the numbering that continuous a plurality of descending sub frames might occur is discontinuous, and such as subframe n is that descending sub frame, subframe n+1 are sub-frame of uplink, subframe n+2 is descending sub frame.This is that subframe n and subframe n+2 are continuous descending sub frames, can the schedule information of correspondence be placed in the 2nd DCI information according to the order of subframe n, subframe n+2.

If what a DCI information was used is the DCI form of corresponding scheduling single codeword transmission, schedule information corresponding to descending sub frame in the 2nd DCI information comprises:

HARQ process number, new data indication information and redundancy version information; Or HARQ process number and new data indication information; Or new data indication information and redundancy version information; Or new data indication information.

If what a DCI information was used is the DCI form of the many codeword transmission of corresponding scheduling, schedule information corresponding to descending sub frame in the 2nd DCI information comprises:

The HARQ process number, code word 1 new data indication information, code word 1 redundancy version information, code word 2 new data indication informations and code word 2 redundancy version information; Or HARQ process number, code word 1 new data indication information and code word 2 new data indication informations; Or code word 1 new data indication information, code word 1 redundancy version information, code word 2 new data indication informations and code word 2 redundancy version information; Or code word 1 new data indication information and code word 2 new data indication informations.

Better, if carry out across carrier dispatching, network equipment 10 determines also to comprise in the 2nd DCI information carrier wave indication territory, and the value in the indication of the carrier wave in the 2nd DCI information territory indicates the value in the territory identical with the carrier wave in a DCI information.

Better, network equipment 10 can also be placed in the ARI information that is used to indicate the PUCCH resource the 2nd DCI information.

Mode two, a kind of new DCI form of definition are used for carrying out the multiframe scheduling.

Concrete, the concrete condition of a plurality of descending sub frames that network equipment 10 is dispatched as required configures respectively the corresponding schedule information of each subframe, such as the HARQ process number, new data indication information and redundancy version information, and adopt C-RNTI to carry out scrambling to the 2nd DCI information.

Accordingly, terminal 20 just knows it is which kind of DCI information in the DCI information of blind check to the C-RNTI scrambling of self correspondence according to the DCI form, such as being DCI form in table 2, determines it is a DCI information; Be the DCI form in non-table 2, determine it is the 2nd DCI information.

Better, when determining the bit number that the 2nd DCI information takies, determine the bit number that current configuration takies to uplink transmission mode and the DCI form corresponding to downlink transfer pattern of terminal, and the bit number that the 2nd DCI information that configures takies is different from the bit number of determining.The bit number that namely under the bit number that takies of the 2nd DCI information and the transmission mode of current configuration to terminal, available DCI form takies is different.

Better, the bit number that the 2nd DCI information takies is except satisfying above-mentioned requirements, can also be completely need be by following requirement:

L _DCI2≥N·L+L _CIF+L _ARI；

Wherein, L _DCI2Be the bit number that the 2nd DCI information takies, L is the bit length that the corresponding schedule information of descending sub frame takies, L _CIFThe bit number that CIF takies, L _ARIIt is the bit number that the ARI territory takies.

If 10 of network equipments are determined the 2nd a DCI information, the descending sub frame after dispatching downlink subframe n is the part or all of subframe in N continuous+1.

Better, in mode two, in order to reduce the blind check number of times of terminal 20, whether network equipment 10 can carry out the multiframe scheduling by high-level signaling configurating terminal 20, and namely whether notification terminal 20 needs to detect new DCI form.

Better, network equipment 10 can be according to the order of subframe numbers, and the schedule information that descending sub frame is corresponding is placed in the 2nd DCI information.Such as arranging as follows: the schedule information that subframe n+1 is corresponding, subframe n+2 is right answers schedule information ..., the schedule information that subframe n+N is corresponding.

If what a DCI information was used is the DCI form of corresponding scheduling single codeword transmission, in the 2nd DCI information, schedule information corresponding to descending sub frame comprises:

If what a DCI information was used is the DCI form of the many codeword transmission of corresponding scheduling, in the 2nd DCI information, schedule information corresponding to descending sub frame comprises:

Mode three, the multiframe that increases in the DCI form are dispatched and are indicated the territory, are a DCI information or the 2nd DCI information in order to indicate this DCI information.

Further, network equipment 10 is when determining to carry out the multiframe scheduling, increase in a DCI information and the 2nd DCI information is used for distinguishing the multiframe scheduling bit field of DCI information type, then will represent that DCI information is the multiframe scheduling bit field that the bit number of a DCI information is placed in a DCI information, and will represent that DCI information is that the multiframe that the bit number of the 2nd DCI information is placed in the 2nd DCI information is dispatched bit field.Such as being set to numerical value " 1 " expression the one DCI information, numerical value " 0 " expression the 2nd DCI information is dispatched bit field with 1 multiframe that is placed in a DCI information, and 0 multiframe that is placed in the 2nd DCI information is dispatched bit field.。

Accordingly, terminal 20 is in the DCI information of blind check to the C-RNTI scrambling of self correspondence, scheduling indicates the numerical value in territory just to know it is which kind of DCI information according to the multiframe in the DCI form, such as if " 1 ", determine that DCI information is a DCI information, if " 0 " determines that DCI information is the 2nd DCI information.

If only have the downlink transfer pattern, network equipment 10 from current configuration to selecting a DCI form DCI form corresponding to the uplink transmission mode of terminal 20.When being configured to downlink transfer pattern 1 such as terminal 20, the bit number that the 2nd DCI information takies can equal the bit number that bit number that DCI form 1A takies or DCI form 1 take.

L _DCI2≥N·L+L _CIF+L _ARI+L _MSI；

Wherein, L _DCI2Be the bit number that the 2nd DCI information takies, L is the bit length that the corresponding schedule information of descending sub frame takies, L _CIFThe bit number that CIF takies, L _ARIThe bit number that the ARI territory takies, L _MSIIt is the bit number that in the 2nd DCI information, multiframe scheduling indication territory takies.

Better, in mode three, for saving resource, whether network equipment 10 can also carry out the multiframe scheduling by high-level signaling configurating terminal 20, namely whether contains the multiframe scheduling in notification terminal 20DCI information and indicates the territory.If carry out the multiframe scheduling, multiframe scheduling indication length of field is 1 bit (can also increase as required the length in multiframe scheduling indication territory), if do not carry out the multiframe scheduling, multiframe scheduling indication length of field is 0 bit.

No matter adopt above-mentioned which kind of mode, if the part subframe in network equipment 10 a scheduling N continuous descending sub frame, network equipment 10 schedule information corresponding to descending sub frame that also need not to be scheduled is placed in the 2nd DCI information.

Are the descending sub frames that are not scheduled in order to allow terminal 20 identify which descending sub frame, network equipment 10 can arrange some specific informations in schedule information corresponding to the descending sub frame of not dispatching.The below enumerates dual mode.

1, network equipment 10 can be arranged to the HARQ process number of the descending sub frame m that do not dispatch identical with the HARQ process number of the descending sub frame m ' of the immediate scheduling in position; Wherein, m is positive integer, and m ' is positive integer, and n≤m '＜m;

Accordingly, terminal 20 is at N that the 2nd DCI information can be dispatched continuously in descending sub frame, determines that the HARQ number of carrying out of the HARQ number of carrying out of descending sub frame m in the 2nd DCI information and descending sub frame m ' is identical, and determining does not have downlink data in descending sub frame m.

Be the subframe that is scheduled such as subframe 1, subframe 2 and 3 is the subframes that are not scheduled, and subframe 2 is identical with the HARQ process number with subframe 1 that 3 HARQ process number arranges.

Terminal 20 just knows that subframe 2 is not the subframe that is scheduled after the HARQ process number of determining subframe 1 and subframe 2 is identical; In like manner after the HARQ process number of determining subframe 1 and subframe 3 is identical, just know that subframe 3 is not the subframe that is scheduled.

2, HARQ process number corresponding to descending sub frame that will not dispatch of network equipment 10 is arranged to invalid value;

Accordingly, terminal 20 determines that the HARQ number of carrying out of descending sub frame m in the 2nd DCI information is invalid value in N the continuous descending sub frame that the 2nd DCI information can be dispatched, and determining does not have downlink data in descending sub frame m.Invalid value specifically which numerical value can arrange as required, and such as for the LTETDD system, the HARQ process number is indicated by 4 bits, and the maximum process number of HARQ is 15 at present, therefore can be set to invalid value by " 1111 " or " 0000 " state.

Better, network equipment 10 can be at descending sub frame n ₁The DL grant that middle transmission is new, wherein n ₁Belong to subframe n+1≤n ₁≤ n _DCI2, n _DCI2Be last descending sub frame in the 2nd schedulable N of a DCI information descending sub frame, adjusting actual scheduling, but in each subframe, the quantity of a DCI information of corresponding same carrier wave is not more than 1.Network equipment 10 is at descending sub frame n ₁In, carry out data according to new schedule information and send.
