Please refer to Fig. 1, the method for resource distribution instruction provided in an embodiment of the present invention, when being applied to base station side, including：

Step 11, base station to terminal send the first Downlink Control Information (DCI) signaling, wherein the first DCI signaling carry to Few two resource blocks distribution instruction (RAI) field, RAI field are used to indicate one group of frequency domain resource.

Here, the first DCI signaling can be the signaling for dispatching shared physical resource, and each RAI field can be with It is used to indicate one group of frequency domain resource continuously or discontinuously.

It is corresponding with above method, as shown in Fig. 2, in terminal side, the method for the resource distribution instruction of the embodiment of the present invention, Including：

Step 21, terminal receives the first DCI signaling that network is sent, wherein the first DCI signaling carries at least two resources Block distribution instruction RAI field, RAI field are used to indicate one group of frequency domain resource continuously or discontinuously.

Here, the first DCI signaling can be the signaling for dispatching shared physical resource, and each RAI field can be with It is used to indicate one group of frequency domain resource continuously or discontinuously.

Step 22, according to the RAI field in the first DCI signaling, the resource of this scheduling is determined.

Here, the resource of this scheduling specifically can be shared physical resource.

In above step, the first DCI can be used for carrying DL transmission authorization (DL grant) instruction or UL transmission authorization instruction (UL grant), specifically, base station can carry more than two RAI fields in the first DCI, each RAI field is for referring to Show one group of frequency domain resource continuously or discontinuously, wherein different RAI fields can be distributed using identical or different resource block Indicating mode is indicated, for example, using continuous resource blocks distribution indicating mode (DL type 2 and UL type 0/1) or waiting It is spaced discontinuous resource block distribution indicating mode (DL type 2), to use less bit, or using bitmap type Resource block distributes indicating mode (DL type 0/1) to indicate the resource of fragmentation.Terminal is believed according to the first DCI that base station is sent It enables, parses RAI field therein, can determine the resource of this scheduling.Specifically, shared physical resource here includes PDSCH resource or PUSCH resource.

Understanding for the ease of network and terminal to DCI signaling can be appointed in network side to terminal side related in advance Parameter.Certainly, the embodiment of the present invention can also be first passed through system message, radio resource control signaling (RRC signaling) in advance by base station At least one of, the configuration parameter of DCI signaling is sent to terminal, wherein the configuration parameter of the DCI signaling includes following At least one of parameter：The field number of RAI field, the corresponding frequency domain of each RAI field, each RAI field are corresponding Frequency domain used in subcarrier spacing, each RAI field corresponding resource distribution instruction mode, each RAI field Bit number, minimum CCE polymerization grade, the dedicated search space NR-PDCCH indicate parameter.

In this way, terminal receives the system message and/or RRC signaling that base station is sent, the first DCI signaling that network is sent is received Configuration parameter, to obtain RAI field number included in the first DCI, the corresponding frequency domain of each RAI field, every Subcarrier spacing used in frequency domain corresponding to a RAI field, the corresponding resource distribution instruction side of each RAI field In the parameters such as formula, the bit number of each RAI field, minimum CCE polymerization grade, the instruction of the dedicated search space NR-PDCCH extremely A kind of few parameter.

Fig. 3 gives a specific example of above embodiments, and in the example, the big bandwidth of 100MHz is divided into 3 by base station Part uses, and wherein first part is the bandwidth of 60MHz, and second part and Part III are 20MHz bandwidth.First part's band Width, which is assigned to only, supports the field of big bandwidth (as supported 100MHz UE) to use；And then allow on remaining 2 20MHz 100MHz terminal and 20MHz terminal carry out resource multiplex.For example, the big bandwidth terminals insensitive to peak rate for part, Base station can configure its bandwidth resources that 0~60MHz is used only, and this section of bandwidth money is indicated using only 1 RAI field Source；And the big bandwidth terminals sensitive to peak rate for other, base station configure its band for being able to use whole 100MHz Wide resource, and be segmented by 3 RAI fields and indicate this 100MHz bandwidth resources.

For indicating the mode of big bandwidth resources above by multiple RAI fields, base station (gNB) can first pass through RRC in advance At least one of signaling and system message, the correlation for being semi-statically configured the first DCI (i.e. DL/UL grant DCI) signaling are matched Parameter is set, such as RAI field number (such as in Fig. 3, the first DCI includes 3 RAI fields) and the corresponding finger of each RAI field Show meaning.

In above-mentioned configuration parameter：

1) RAI field number included in the first DCI indicates the quantity of the RAI field carried in DCI, for example, 3 RAI field.

2) which frequency domain what the corresponding frequency domain of each RAI field indicated each RAI field instruction is.For example, That the first RAI field indicates is 0~60MHz in bandwidth of operation, and that the 2nd RAI field indicates is the 60MHz in bandwidth of operation ~80MHz, the instruction of the 3rd RAI field is 80MHz~100MHz in bandwidth of operation, in range above instruction, can be with The starting frequency point of bandwidth of operation is reference.

3) subcarrier spacing used in frequency domain corresponding to each RAI field, for example, RRC signaling can be passed through Indicate frequency domain indicated by the first RAI field use 60kHz subcarrier spacing, or by system message indicate 0~ 60MHz frequency domain uses the subcarrier spacing of 60kHz.

4) the corresponding resource distribution instruction mode of each RAI field, for example, the first RAI field is using continuous or between waiting Indicating mode is distributed every discrete resource block；And the 2nd RAI field and the 3rd RAI field all use the resource of bitmap form Block distributes indicating mode.In another example the RBG that RBG size=12 RB, the 2nd RAI and the 3rd RAI that the first RAI is used are used Size=4 RB, wherein RBG (RB group) is the frequency domain smallest particles degree of resource indicating unit.

5) bit number of each RAI field, for example, gNB can pass through each RAI field of RRC signaling explicit instruction Used bit number；Alternatively, which frequency domain model is field by the instruction of each RAI field can be such as according to other parameters It encloses, subcarrier spacing used in frequency domain corresponding to each RAI field, the corresponding resource allocation of each RAI field refer to Show at least one of mode parameter, according to the first preset rules, determine bit number corresponding at least one parameter, To obtain the bit number of RAI field.

6) minimum CCE polymerization grade.CCE polymerization grade used in each DCI is smaller, the information bit that can be carried Number is also fewer.In terms of the angle of base station, with the increase of RAI field, it may be necessary to the bigger CCE polymerization grade of distribution with by these Information has indicated.In terms of terminal point, if it is possible to know the CCE polymerization grade range that base station is actually used in advance, then may be used To reduce the search space of CCE polymerization grade, and then DCI blind detection complexity can be reduced；

Specifically, gNB can pass through minimum CCE polymerization grade used in RRC signaling explicit instruction base station；Alternatively, eventually End can be according to other parameters, and what is such as indicated by RAI field number, each RAI field is which frequency domain, each RAI It is subcarrier spacing used in frequency domain corresponding to field, the corresponding resource distribution instruction mode of each RAI field, each At least one of the bit number of RAI field parameter is determined corresponding at least one parameter according to the second preset rules Minimum CCE polymerization grade, to obtain minimum CCE polymerization grade used in base station；

7) the dedicated search space NR-PDCCH instruction；

Here, in order to reduce UE blind examination complexity, base station can also lead to other than it can limit minimum CCE polymerization grade It crosses other modes and limits the search space CCE, a subset is such as marked off in the search space NR-PDCCH, that is, is defined dedicated The search space NR-PDCCH carries the DCI signaling of RAI dedicated for transmission.At this moment, terminal only needs in the specific subset These DCI signalings are detected, to reduce blind examination complexity.Specifically the mode of the definition search space NR-PDCCH subset includes At least one of following manner：Limit the start offset, disabling part CCE polymerization grade, disabling part of the search space CCE PDCCH position candidate etc..

As another implementation, in the embodiment of the present invention, base station can also also carry following in the first DCI signaling At least one of configuration parameter：The field number of RAI field, the corresponding frequency domain of each RAI field, each RAI field Subcarrier spacing used in corresponding frequency domain, the corresponding resource distribution instruction mode of each RAI field, each RAI word The bit number of section, minimum CCE polymerization grade, the dedicated search space NR-PDCCH indicate parameter.Terminal receives the first DCI signaling And the above-mentioned parameter wherein carried is parsed, to realize instruction of the base station to relevant parameter.

In addition, the realization about RAI field, can also redefine instruction in such a way that the prior art is similar The other modes of one group of frequency domain resource can also increase more subfields on the basis of existing technology in RAI field, Transmit more information.Although in addition, it is necessary to, it is noted that be retouched by taking DL grant DCI as an example in the embodiment of the present invention It states, but scheme described in the embodiment of the present invention is also applied for UL grant DCI.

In the above manner, which CCE polymerization grade is terminal be known that through, it is blind in which PDCCH position candidate Examine the first DCI signaling, and can meaning indicated by each bit in correct understanding signaling decoding mode and signaling, thus real The instruction of distributed resource is showed.

It is a kind of semi-static RAI indicating means that above embodiments, which give, i.e. base station passes through RRC signaling and/or system Message will include in advance several RAI fields and each RAI field pair in semi-static its used first DCI of informing terminal Answer parameter.The following embodiment of the present invention will provide a kind of more dynamic indicating means, that is, pass through optional 2nd DCI signaling Indicate additional RAI field, and terminal just knows whether that there are the 2nd DCI letters only after receiving the first DCI signaling It enables, and when there are the 2nd DCI signaling, more RAI fields is obtained by the 2nd DCI and are indicated.

Step 41, base station sends the 2nd DCI signaling to terminal, wherein the 2nd DCI signaling carries at least one RAI field And it is used to indicate whether that there are the first indication fields of the 3rd DCI signaling.

Here, here, the 2nd DCI signaling can be the signaling for dispatching shared physical resource.The shared physics money Source includes PDSCH resource or PUSCH resource.

Step 42, base station sends the 3rd DCI signaling, the 3rd DCI to the terminal when there are the 3rd DCI signaling Signaling carries one or more RAI fields.

Here, the 3rd DCI signaling can serve to indicate that shared physical resource.

In above step, if the first indication field indicates that the 3rd DCI signaling is not present, step 42 is not executed, at this time base It stands and only sends the instruction that the 2nd DCI signaling carries out resource allocation.

It is corresponding with above method, as shown in figure 5, in terminal side, the method for the resource distribution instruction of the embodiment of the present invention, Including：

Step 51, terminal receives the 2nd DCI signaling that network is sent, wherein the 2nd DCI signaling carries at least one RAI Field and it is used to indicate whether that there are the first indication fields of the 3rd DCI signaling.

Here, in step 51, according to the first indication field, it can be determined that whether there is the 3rd DCI of subsequent transmission out Signaling, and if it exists, then enter step 52.

Step 52, when there are the 3rd DCI signaling, the 3rd DCI signaling that network is sent, the 3rd DCI signaling are received Carry one or more RAI fields.

Step 53, according to the RAI field in the 2nd DCI signaling and the 3rd DCI signaling, the resource of this scheduling is determined.

Here, the resource of this scheduling specifically can be shared physical resource.

In above step 51, if judging, there is no the 3rd DCI signalings, 54 can be entered step, at this time according to second RAI field in DCI signaling determines the shared physical resource of this scheduling.

In above method, the 2nd DCI signaling can be used for carrying DL transmission authorization (DL grant) instruction or UL transmission authorization It indicates (UL grant), specifically, base station can carry 1 or 2 or more RAI field in the 2nd DCI signaling, each RAI field is used to indicate one group of frequency domain resource continuously or discontinuously, wherein different RAI fields can be using identical or not Same resource block distribution indicating mode is indicated, for example, distributing indicating mode (DL type 2 and UL using continuous resource blocks Type 0/1) or discontinuous resource block distributes indicating mode (DL type 2) at equal intervals, to use less bit, or uses The resource block of bitmap type distributes indicating mode (DL type 0/1) to indicate the resource of fragmentation.Terminal is sent out according to base station The 2nd DCI signaling sent parses RAI field therein, can determine the resource of this scheduling.Specifically, shared object here Managing resource includes PDSCH resource or PUSCH resource.

Understanding similar with previous embodiment, for the ease of network and terminal to DCI signaling, can be in advance in network side Relevant parameter is appointed with terminal side.It is of course also possible to first pass through system message, radio resource control signaling (RRC in advance by base station At least one of signaling), the configuration parameter of the 2nd DCI signaling is sent to terminal, wherein the 2nd DCI signaling is matched Setting parameter includes at least one of following parameter：It is the field number of RAI field, the corresponding frequency domain of each RAI field, every Subcarrier spacing used in the corresponding frequency domain of a RAI field, the corresponding resource distribution instruction mode of each RAI field, The bit number of each RAI field, minimum CCE polymerization grade, the dedicated search space NR-PDCCH indicate parameter.In this way, terminal System message and/or RRC signaling that base station is sent are received, the configuration parameter for the 2nd DCI signaling that network is sent is received, to obtain RAI field number, the corresponding frequency domain of each RAI field included in the 2nd DCI, corresponding to each RAI field The ratio of subcarrier spacing used in frequency domain, the corresponding resource distribution instruction mode of each RAI field, each RAI field At least one of the parameters such as special number, minimum CCE polymerization grade, the instruction of the dedicated search space NR-PDCCH parameter.
