Fig. 4 is a kind of flow chart of data transmission method shown according to an exemplary embodiment, as shown in figure 4, the number According to transmission method in implementation environment shown in FIG. 1, which to include the following steps.

Step 401, base station generate the first scheduling information.

First scheduling information can be DCI or sDCI, and the first scheduling information can indicate the first downlink resource and at least Identical destinations traffic data are carried on one the second downlink resource.

When data transmission method is applied in 5G communication systems, the first scheduling information is sDCI, at this point, under above-mentioned first Row resource and at least one second downlink resource can be sub-slots resource.

When data transmission method is applied in LTE communication system, the first scheduling information is DCI, at this point, under above-mentioned first Row resource and at least one second downlink resource can be time interval resource.

Optionally, above-mentioned first downlink resource and at least one second downlink resource can be located in same subframe, also may be used To be located in different subframes.

In actual implementation, above-mentioned first scheduling information may include that the first time-frequency location instruction information and sending times refer to Show information.

Wherein, the first time-frequency location instruction information can be used for dispatching the first downlink resource, can be used for scheduling first Downlink resource and at least one second downlink resource.When the first time-frequency location instruction information is for dispatching the first downlink resource, First time-frequency location instruction information can indicate to carry the first object time-frequency of destinations traffic data in the first downlink resource Position, as described above, communication data is carried on the PDSCH carried in time slot or sub-slots, in other words, above-mentioned destinations traffic Data are normally carried on PDSCH, and therefore, the first object time-frequency location indicated by above-mentioned first time-frequency location instruction information can With in the PDSCH that the first downlink resource carries.The first time-frequency location instruction information for dispatch the first downlink resource and When at least one second downlink resource, above-mentioned first time-frequency location instruction information in addition to can indicate first object time-frequency location it Outside, the second target time-frequency location that destinations traffic data are carried in each second downlink resource is also can indicate that, with institute above Similarly, it is a certain that the second target time-frequency location in a certain second downlink resource can be located at this to the first object time-frequency location stated In the PDSCH of second downlink resource carrying.

Sending times instruction information can serve to indicate that the number n of at least one second downlink resource, wherein n be more than Or the positive integer equal to 1, sending times instruction information can be carried out by the physical layer or downlink wireless Resource Control Layer of base station Configuration.

In practical application, sending times instruction information can be had correctly received the probability of information by base station according to UE singles It is configured, optionally, base station can be based on following formula and be configured to sending times instruction information:

N=Ceiling (log (1-b%) (1-a%) -1).

Wherein, n be sending times indicate information indicated by least one second downlink resource number, a% be with The communication service of high reliability demand requires UE to have correctly received the probability of information, and b%, which is UE singles, can have correctly received letter The probability of breath, Ceiling are the operation that rounds up.

For example, the probability that UE singles can have correctly received information is 99%, and the communication industry with high reliability demand It is 99.9999% that business, which requires UE to have correctly received the probability of information, then the number of at least one second downlink resource can be:n =log_0.010.000001-1=2, base station can configure sending times based on the number of at least one second downlink resource and refer to Show information.

It should be pointed out that the above-mentioned formula that the embodiment of the present disclosure is provided is only exemplary, it is not used to limit The protection domain of the disclosure processed.

Step 402, base station send the first scheduling information and destinations traffic data by the first downlink resource.

Base station can send first scheduling information by the PDCCH that the first downlink resource carries, meanwhile, base station can lead to The PDSCH for crossing the carrying of the first downlink resource sends the destinations traffic data.

Step 403, base station send destinations traffic data by least one second downlink resource.

Similarly, base station can be carried by the second downlink resource of each of at least one second downlink resource PDSCH sends the destinations traffic data.

As described above, the first time-frequency location instruction information can be only used for the first downlink resource of scheduling, in this case, The second scheduling information can also be carried in the PDCCH of each second downlink resource carrying, wherein each second scheduling information is used In dispatch its corresponding to the second downlink resource, for example, certain second downlink resource at least one second downlink resource is held The second scheduling information is carried in the PDCCH of load, then second scheduling information can be used for dispatching certain second downlink resource.

Optionally, each second scheduling information may include the second time-frequency location instruction information, which refers to Show that information can indicate to carry the third mesh of destinations traffic data in the second downlink resource corresponding to second scheduling information Time-frequency location is marked, similarly with above description, which is located at second corresponding to second scheduling information In the PDSCH of downlink resource carrying.In actual implementation, the third target time-frequency location in the second different downlink resources can phase It together, can not also be identical.

It should be pointed out that the second scheduling information can be identical with the type of the first scheduling information, it that is to say, when the first tune When degree information is DCI, the second scheduling information is also DCI, and when the first scheduling information is sDCI, the second scheduling information may be sDCI.In addition, the blind examination information corresponding to the first scheduling information can also phase with the blind examination information corresponding to the second scheduling information Together, in this way, UE is after blind examination obtains the first scheduling information in the PDCCH that the first downlink resource carries, can be based on this first The corresponding blind examination information of scheduling information carries out blind examination to obtain the second scheduling letter to the PDCCH that each second downlink resource carries Breath carries out the time delay of blind examination so as to greatly reduce UE to the PDCCH that each second downlink resource carries.

Certainly, in the first time-frequency location instruction information for dispatching the first downlink resource and at least one second downlink resource When, the second downlink resource carrying PDCCH in can need not carry above-mentioned second scheduling information.

Step 404, UE receive the first scheduling information that base station is sent by the first downlink resource.

UE can carry out blind examination to the PDCCH that the first downlink resource carries, and to obtain first scheduling information, while UE is also The corresponding blind examination information of first scheduling information can be obtained, for example, the blind examination information can be the information such as polymerization grade.

Step 405, UE receive destinations traffic data based on the first scheduling information on the first downlink resource.

As described above, the first scheduling information may include the first time-frequency location instruction information, first time-frequency location instruction Information can indicate to carry the first object time-frequency location of destinations traffic data in the first downlink resource, and therefore, UE is being obtained To after the first scheduling information, target can be received on above-mentioned first object time-frequency location according to the instruction of the first scheduling information and led to Letter data.

Step 406, when being not properly received destinations traffic data on the first downlink resource, UE be based on first scheduling Information receives destinations traffic data at least one second downlink resource successively, is up to having correctly received destinations traffic data Only.

In practical application, the probability that UE singles have correctly received communication data is not generally possible to be 100%, that is to say, real When border is realized, UE can not may have correctly received destinations traffic data, in this case, UE on the first downlink resource It needs to receive destinations traffic data at least one second downlink resource successively, is up to having correctly received destinations traffic data Only.

Optionally, UE can indicate that information determines at least one second downlink based on the sending times in the first scheduling information The number n of resource, and the time-frequency location of the number n and the first downlink resource based at least one second downlink resource determine at least The time-frequency location of one the second downlink resource, then UE can based on the time-frequency location of at least one second downlink resource, according to It is secondary that destinations traffic data are received at least one second downlink resource, until having correctly received destinations traffic data.

As described above, the first downlink resource and at least one second downlink resource can be located in same subframe, it can also It is located in different subframes, in the following, the embodiment of the present disclosure will be under both of these case, UE be based at least one second downlink The number n of resource and the time-frequency location of the first downlink resource determine the technology mistake of the time-frequency location of at least one second downlink resource Journey illustrates:

The first situation, the first downlink resource and at least one second downlink resource are located at same subframe (same subframe For the first subframe) in, in this case, UE can be by n downlink resource adjacent with the first downlink resource in the first subframe It is determined as at least one second downlink resource, for example, the first downlink resource is the 1st sub-slots in the first subframe, and n is 2 When, UE can by the first subframe the 2nd sub-slots and the 3rd sub-slots be determined as at least one second downlink resource.

The second situation, the first downlink resource and at least one second downlink resource are located in different subframes, In this case, UE can determine the n subframe adjacent with the subframe (referred to as the second subframe) where the first downlink resource For target-subframe, wherein each target-subframe may each comprise second downlink resource, and then UE can obtain the first downlink Time-frequency location of the resource in the second subframe, and the time-frequency location based on the first downlink resource in the second subframe determine each Time-frequency location of second downlink resource in affiliated target-subframe, that is to say, UE can be by the first downlink resource in the second son Time-frequency location in frame is determined as time-frequency location of each second downlink resource in affiliated target-subframe.For example, under first Row resource is the 1st sub-slots in the second subframe, and when n is 2, and UE can be by and in the time domain position adjacent with the second subframe Two subframes after second subframe are determined as target-subframe, wherein each target-subframe may include one second First sub-slots in each target-subframe can be determined as the second downlink resource by downlink resource, then, UE.

As described above, the first scheduling information can be only used for the first downlink resource of scheduling, can be used under scheduling first Row resource and at least one second downlink resource, below the embodiment of the present disclosure will be under both of these case, UE be successively at least one Destinations traffic data are received on a second downlink resource, the technical process until having correctly received destinations traffic data carries out Explanation:
