Sample brings resource collision problem.Due to being in Physical Downlink Shared Channel in existing downlink data transmission scheme
PDCCH is sent before (PDSCH, Physical Downlink Shared Channel) transmission, UE is first examined
Scheduling of resource and distribution information that PDCCH obtains PDSCH are surveyed, Data Detection is then carried out, but such as
When fruit has mMTC business to need scheduling, the resource for having distributed to eMMB UE can be taken, money is caused
Source is collided, and if eMMB UE are still detected to receive downlink data to the resource, then may be made
Into the downlink data mistake of reception, the reliability of UE downlink datas reception have impact on.

After the principle of the present invention is described, below in conjunction with Fig. 2 to lower line number provided in an embodiment of the present invention
Illustrated according to the implementing procedure of transmission method.
As shown in Fig. 2 downlink data transmission method provided in an embodiment of the present invention may comprise steps of：
S21, for UE generate downlink data waiting for transmission.
If network side determines that the running time-frequency resource for distributing to the UE is occupied for other UE scheduling due to needing
Also need to include in used time, the then downlink data generated in the step s 21 to be used to identify and distribute to this originally
UE but by the mark data of other UE running time-frequency resources taken.
S22, UE be scheduled running time-frequency resource on transmit downlink data.
Specifically, in step S22, the downlink data generated in step S21 can be mapped to and be adjusted for UE
The running time-frequency resource of degree is (it should be appreciated that running time-frequency resource here should be except the running time-frequency resource taken by other UE
Running time-frequency resource in addition) on be transmitted, that is, in step S22, the lower line number of the lateral UE transmission of network
Include in for being designated UE distribution but by the mark data of other UE running time-frequency resources taken.
Optionally, when it is implemented, before network side execution step S21, the UE points can also be judged as
Whether the resource matched somebody with somebody is taken by other UE, if it is judged that being accounted for for the UE resources distributed by other UE
Used time, the then downlink data for including above-mentioned mark data in generation is simultaneously transferred to terminal.For example, network side
It is determined that when distributing to the resource of the UE due to needing occupied for URLLC UE scheduling resources, in step
Generation includes the downlink data of mark data in S21, and sends the downlink data of generation in step S22
To terminal.If distributing to the resource of the UE does not have occupied, network side can according to prior art to this
User sends PDCCH.
Preferably, the embodiment of the present invention provides the following two kinds mark by the reality of other UE running time-frequency resources taken
Mode is applied, is introduced individually below.
The first embodiment, mark data are used to identify by the start stop bit of other UE running time-frequency resources taken
Put
Under this embodiment, network side can be used and the UE special symbol sequences arranged or specific symbol
Number feature identifies the running time-frequency resource taken by other UE.
For the ease of description, the frequency domain resource set for being originally used for UE distribution is designated as Fset, is UE distribution
OFDM symbol be designated as Oset, by taking Fig. 1 as an example, it is assumed that Fset={ f1, f2... ... f16, f17,
Oset={ K, K+1, K+2 ... ... K+13 }.
In some scheduling instance, network side is due to needing for URLLC UE scheduling resources, by frequency domain resource
{f3, f4, f5……f14, f15, the corresponding scheduling of resource of OFDM symbol { K+4, K+5, K+6 } is to URLLC
UE, then network side can use the resource-niche that is taken by other UE of special symbol sequence pair arranged with UE
Put and be identified.With network side by frequency domain resource { f3, f4, f5……f14, f15, OFDM symbol K+4,
K+5, K+6 } corresponding scheduling of resource to URLLC UE exemplified by, as shown in Figure 3 a, by URLLC UE
The resource area of occupancy is rectangle (lattice region in Fig. 3 a), then network side can be by rectangle
The resource location of diagonal or four drift angles is identified so that UE, which is known, is assigned to URLLC UE's
Running time-frequency resource.
For example, network side identifies frequency domain resource f respectively16Resource corresponding with OFDM symbol serial number K+6
Block and frequency domain resource f2Resource block (the grey in such as Fig. 3 a corresponding with OFDM symbol serial number K+4
Shown in pattern)；Or network side identifies frequency domain resource f respectively16It is corresponding with OFDM symbol serial number K+4
Resource block, frequency domain resource f16Resource block corresponding with OFDM symbol serial number K+6, frequency domain resource
f2Corresponding with OFDM symbol serial number K+4 resource block and frequency domain resource f2With OFDM symbol sequence number
For the corresponding resource blocks of K+6, (as shown in the gray pattern in Fig. 3 b, lattice region is in Fig. 3 b
The resource that URLLC UE take).So, UE is when the downlink data to receiving is detected, can be with
The rectangular area for skipping network side mark is detected by remaining region.
Second embodiment, mark data are used and the UE special symbol sequences arranged or special symbol
Feature and mark data is transmitted using different transimission powers.

The running time-frequency resource matched somebody with somebody extends corresponding time span backward, that is, the time span that the running time-frequency resource extended takes with
The time span that the running time-frequency resource of original allocation takes is identical.I.e. network side can based on occupied resource when
Domain information, does corresponding extension in time domain, if for example, network side is initially allocated to 2 in the UE
Individual OFDM symbol is occupied, then network side is automatic 2 symbol lengths that extend of resource that the UE is distributed,
For transmitting the data that the resource taken by other UE should be transmitted.
Network side is initially the resource of UE distribution still by taking the resource allocation schematic diagram shown in Fig. 3 c as an example, such as
Fruit which part resource is taken by other UE, and network side will can backward prolong for the running time-frequency resource that UE is distributed
Exhibition 2 OFDM symbols, i.e. network side are that the running time-frequency resource that UE extends is OFDM sequence numbers from (K+14)
~(K+15), and it can be f1-f9 that frequency domain, which takes resource, then resource allocation schematic diagram such as Fig. 3 e after extending
Shown (Fig. 3 e grey parts).
Certainly, network side, also according to the frequency domain information for the UE initial resources distributed, will be the UE
The frequency domain resource of distribution is extended backward, the time span of extension by the total resources that are taken by other UE and
The frequency domain resource of UE distribution is determined.
Network side is initially the resource of UE distribution still by taking the resource allocation schematic diagram shown in Fig. 3 c as an example, net
The resource block quantity that network side is compensated as needed is preferentially extended in frequency, after whole frequency bandwidth takes
A symbol extends still further below, and the resource allocation schematic diagram after extension is as illustrated in figure 3f (Fig. 3 f grey parts).
In downlink data transmission method provided in an embodiment of the present invention, if network side determines to be initially UE points
Other UE are scheduled in the resource matched somebody with somebody in use, then including user in the downlink data sent to UE
Mark is by the mark data of other UE running time-frequency resources taken so that UE can be according to mark data, really
Which fixed resource is occupied by other UE, so, and UE can be avoided by it when carrying out Data Detection
The resource that his UE takes, it is to avoid receive wrong data, and influence the reliability of UE data receivers.Separately
Outside, in downlink data transmission method provided in an embodiment of the present invention, if distributing to certain UE resource by it
His UE takes, and network side can also be terminal scheduling compensating for resource, and resource is taken by other UE to transmit
The data transmitted, based on this, mark data may be used to indicate that the resource information that UE is its compensation,
If UE TTI is not fixed, network side can do corresponding extension in time domain, will be UE distribution
Resource extend automatically in time domain, take the data transmitted of resource by other UE to transmit.
