Embodiment three,

The embodiment of the present invention provides a kind of interference identification method, is applied to first base station, as shown in figure 4, including：

Step 401：Receive the interference measurement signal at least one 2nd UE that the first UE of self-management is reported The first measurement result；

Step 402：It is determining from least one 2nd UE to be deposited with the first UE based on first measurement result In specific 2nd UE of interference.

In conjunction with previous embodiment, the first base station is to control the first UE progress interference measurement signal monitorings of self-management Base station.

In base station side, it is necessary first to carry out the selected of the first UE, specifically selected mode is referring to being described below：

The of the interference measurement signal at least one 2nd UE that the first UE for receiving self-management is reported Before one measurement result, the method further includes：

The resource allocation information being made of one group of running time-frequency resource is sent at least one UE of self-management, so that described Each UE at least one UE some or all of is based in one group of running time-frequency resource intercepting interference measurement signal；

Receive the second measurement result that each UE is reported, wherein include at least and connect in second measurement result Receive signal strength, with the presence or absence of one or more in the judging result of potential high reject signal；

Based on the second measurement result that each described UE is reported, determined by strongly disturbing from least one UE First UE.

That is, before determining the first UE, the inspection that at least one UE carries out interference measurement signal can be controlled in advance It surveys, the first UE for needing to choose then is determined according to the second measurement result.

Specifically, flow shown in Figure 5：

Step 501：One group of running time-frequency resource is arranged in multiple base stations in specific region, in the running time-frequency resource of the agreement, Forbid base station to send message, and UE is only allowed to send message；

Step 502：Base station configures one in one group of running time-frequency resource and interference measurement signal type for the UE of its service Kind is a variety of；Wherein, base station configures the identical interference measurement signal type for all UE serviced；And UE understands in institute It states in one group of running time-frequency resource, the DL signals of eNB transmissions will not be received；

Step 503：UE, which is based on base station, to be dispatched or is determined based on autonomous, is selected in one be configured group running time-frequency resource Some or all of orthogonal resource on send interference measurement signal.

Step 503A：Preferably, base station scheduling portion or whole UE are some or all of in one group of running time-frequency resource Orthogonal resource on send the interference measurement signal；Also, base station avoids dispatching multiple UE at the same time same by scheduling The interference measurement signal is sent on time-frequency orthogonal resource；

Step 503B：UE is dispatched based on base station, some or all of in one be configured group running time-frequency resource just It hands over and sends the interference measurement signal in resource；

Step 504：UE, which is based on base station, to be dispatched or is determined based on autonomous, is selected in one be configured group running time-frequency resource Some or all of orthogonal resource on attempt intercept interference measurement signal；

Step 505：UE measures residual signal intensity in the channel after rejecting the interference measurement signal that this base station configures, and According to preset rules, report measurement results.Wherein, the measurement result includes total received signal strength (RSSI), rejects this base Stand configuration interference measurement signal after channel in residual signal intensity, around whether there is potential high reject signal judgement As a result one or more in.The preset rules include：The direct report measurement results of UE；Alternatively, the UE will be rejected Residual signal intensity is compared with certain threshold in channel after the interference measurement signal of this base station configuration, if it is greater than (or being more than Equal to) thresholding, then report measurement results, otherwise, not report measurement results；

Step 506：Based on the measurement result that UE is reported, identification of base stations goes out around the UE with the presence or absence of potential " UE-UE Strong jamming to ".

UE, which is based on base station, to be dispatched or is determined based on autonomous, select part in one be configured group running time-frequency resource or It attempts to intercept interference measurement signal on whole orthogonal resources.

The UE is based on base station and configures or independently determine, selects in base station down scheduling unit, the not used scheduling in base station The not scheduled base station uplink scheduling unit for doing uplink of unit, the UE and the UE are not scheduled and do uplink It attempts to intercept above-mentioned interference measurement signal in one or more scheduling units in the uplink and downlink mixed scheduling unit of base station.

UE actually selects to attempt to intercept above-mentioned interference measurement signal in which scheduling unit type, both may be by base Stand configuration (being determined by base station), it is also possible to independently determined by UE.

UE measures residual signal intensity in the channel after rejecting the interference measurement signal that this base station configures, and according to default Rule, report measurement results：

Base station configures the identical interference measurement signal type for all UE serviced, therefore, when the first UE is intercepted To this base station configure the interference measurement signal when, the first UE can judge that the interference measurement signal is serviced by this base station Other UE send out, without being sent out by other UE of this non-base station.First UE comes from adjacent base station to effectively identify The interference signal that other UE are sent out, it is therefore desirable to which " filtering " falls the interference signal that other UE of this base station are sent out.Specifically, first UE, from the interference measurement effect of signals deleted this base station in signal and configured is received, then, then is measured by interfering deleting technique Finish after signal is deleted remaining signal strength in channel.

It is that the first UE is configured by one group by one or more methods in broadcast channel, system message, RRC signaling The resource allocation information of running time-frequency resource composition.

Based on first measurement result, determine there is interference with the first UE from least one 2nd UE Specific 2nd UE, including：

The 2nd UE for meeting preset condition is chosen from least one 2nd UE, it is dry as existing with the first UE The 2nd UE of feature disturbed；

Wherein, the preset condition includes at least one of：

The 2nd UE chosen and the first UE is respectively at uplink in synchronization and sends state and downlink reception State；

The 2nd UE chosen uses identical or adjacent frequency domain resource with the first UE.

After determining specific 2nd UE with the first UE in the presence of interference at least one 2nd UE, the side Method further includes：

Interference coordination is carried out to the first UE and specific 2nd UE.

" the UE-UE strong jammings to " refers to working as the two UE synchronizations, and one is in downlink receiving state, another It is a in uplink send state, and just both using identical or adjacent frequency (such as RB) when, in uplink send state UE transmitted by uplink signal may cause strong jamming to the downlink data reception behavior features of the UE in downlink receiving state. Two UE it is noted that so-called in " UE-UE strong jammings to " are under the jurisdiction of different base stations.

Seen from the above description, only when multiple conditions meet simultaneously (i.e. simultaneously, with frequently, incorgruous), " UE-UE is capable and experienced Disturb to " two UE of centering are likely to unidirectional strong jamming phenomenon occur；And when wherein any one condition is unsatisfactory for, interference is not It can set up.Therefore the behavior that interferes with each other between two UE in " UE-UE strong jammings to " is probable, and not necessarily.

After adjacent 2 base stations have known " UE-UE strong jammings to " information, can have by interference coordination technique between station Effect inhibits the interference of UE to UE between two neighboring base station.A kind of possible implementation method is as shown in Figure 6 and Figure 7, based on dry between station Disturb the inhibition flow diagram that UE to UE is interfered between the station of coordination.Base station gNB1 knows the UE1 and adjacent base station that it is serviced The UE2 that gNB2 is serviced is " UE-UE strong jammings to ".GNB1 is in order to inhibit the uplink of UE2 to the dry of the downlink reception of UE1 It disturbs, gNB1 starts diagram flow.Certainly, gNB2 can also start similar procedure, to inhibit the uplink of UE1 under UE2 The interference that row receives, does not repeat here.

Process step is as follows：

Step 701：GNB1 is determined<UE1 and UE2>For " UE-UE strong jammings to "；

Step 702：For gNB1 by backhaul interfaces between station, the UL that UE2 is subscribed to gNB2 dispatches behavior.Wherein, described " UL for subscribing to UE2 dispatches behavior ", refers to：When the subscribed user UE2 of subscribed base station gNB2 scheduling is in some time-frequency When doing UL transmission in resource (the specific RB set PRB set 2 of such as slot n), gNB2 ensure UE2 it is practical be UL transmission when Carve sometime (such as the slot p, p before (such as slot n)<N), (such as by the UL of above-mentioned UE2 scheduling time-frequency scheduling resources information UE 2 does UL transmission on the specific RB set PRB set 2 of slot n) it notifies to give subscriber base station gNB1；

Step 703：The subscribed user UE2 of subscribed base station gNB2 scheduling does UL transmission on some running time-frequency resource. For example, gNB2 dispatches UE2 in slot n-k does UL transmission in the PRB set 2 of slot n；

Step 704：Subscribed base station gNB2 UE2 is practical do UL transmission at the time of (such as slot n) before some when Carve (such as slot p, p<N), by backhaul interfaces between station, the UL of the user UE2 of subscription is dispatched into time-frequency scheduling resource information It notifies to give subscriber base station gNB1.For example, gNB2 is in slot p (n-k<p<N) in, by backhaul interfaces between station, by UE2 UL scheduling time-frequency scheduling resource information (such as UE 2 does UL transmission on the specific RB set PRB set 2 of slot n) notice to gNB1；

Step 705：When subscriber base station gNB1 is that this base station in " UE-UE strong jammings to " services UE and does descending scheduling, Avoid having distributed to the resource that other UE (i.e. booking reader) in " UE-UE strong jammings to " do UL transmission as possible.For example, in this reality It applies in example, it is assumed that gNB1 determines that slot n are downlink transmission direction, and when determination will dispatch UE1 and do DL transmission, and gNB1 is kept away as possible Exempt to have distributed to the frequency domain resource PRB set 2 that UE2 does UL transmission for UE1 scheduling.It is noted that<UE1 and UE2>For " UE-UE is strong Interference to ", and UE1 is serviced by gNB1, and UE2 is serviced by gNB2.

Obviously, by above-mentioned flow, strong jamming problem between UE to UE can effectively be inhibited.

Example IV,

An embodiment of the present invention provides a kind of interference identification methods, are applied to the second base station, to the 2nd UE of self-management Configuration sends window by first that first group of running time-frequency resource forms；

It is possible to further shown in Figure 8, detailed process may include：

Step 801：The transmission window being made of one group of running time-frequency resource is sent at least one 2nd UE of self-management；

Step 802：It controls at least one 2nd UE to send in window described first, sending interference to the first UE surveys Measure signal；

Wherein, the 2nd UE is different from the serving BS of the first UE；Described first sends the 2nd UE in window Signal transmitting and receiving direction, with its where serving BS signal transmitting and receiving direction it is identical or different.

It is described send the transmission window being made of one group of running time-frequency resource at least one 2nd UE of self-management before, institute The method of stating further includes：

One group of running time-frequency resource is determined at least one adjacent base station, is held consultation at least one adjacent base station, with Second group of running time-frequency resource as reserved resource and is negotiated not send downlink information in the reserved resource；

The signal type of one group of running time-frequency resource and interference measurement signal is configured at least one UE of self-management；

At least one UE of scheduling self-management is sent on all or part of orthogonal resource of one group of running time-frequency resource The interference measurement signal.

The agreement method can be received text regulation, OAM configuration, stand between by backhaul coordination the methods of in It is one or more.

Due to only allowing UE to send message in one group of running time-frequency resource, and base station is forbidden to send message wherein, because This, when perceiving interference in UE is in one group of running time-frequency resource, interference signal can only come from other UE.

As shown in figure 9, may include multiple scheduling units in one group of running time-frequency resource, and include in each scheduling unit Multiple orthogonal resources.Wherein, the scheduling unit is subframe or slot or mini-slot；And when the multiple orthogonal Frequency resource may use same or different running time-frequency resource block size.

Preferably, one group of periodic running time-frequency resource is arranged in multiple base stations in specific region, i.e., adjacent scheduling unit it Between there is identical time domain interval, and the orthogonal resource distributed in each scheduling unit

Base station is that UE configures above- mentioned information by one or more methods in broadcast channel, system message, RRC signaling.

In one group of running time-frequency resource of the agreement, base station is forbidden to send message, and only allows the standard of UE transmission message Change language to illustrate.I.e. in terms of the sides UE, UE understands in one group of running time-frequency resource, will not receive the DL signals of eNB transmissions.

Optionally, when base station has been dispatched to one group of running time-frequency resource, base station may through-rate matching (Rate ) etc. matching technologies get around the above-mentioned time/frequency source block being reserved；And UE is when doing data demodulation, it also can through-rate matching Technology gets around the above-mentioned time/frequency source block being reserved, i.e., uses consistent understanding with base station side.

The interference measurement signal type can be multiplexed the existing cell common reference signals of LTE, as CRS, CSI-RS, PSS, SSS, PRS, DRS etc.；Alternatively, reusable NR it is existing and it is following may definition other cell common reference signals, such as NR- CRS, NR-CSI-RS, NR-PSS, NR-SSS, NR-PRS, NR-DRS, NR etc.；Alternatively, can also be the one of base station self-defining A little others cell common reference signals；

Base station avoids dispatching multiple UE at the same time and sends the interference measurement on same time-frequency orthogonal resource by scheduling Signal, it is preferred that it is only upper in one group of running time-frequency resource by base station scheduling authorization UE to send the interference measurement signal, Purpose is, can be based on base station and dispatch, avoid dispatching at the same time multiple UE sent on same time-frequency orthogonal resource it is described dry Disturb measuring signal.

In this way, in a specific orthogonal resource, can only at most there be 1 UE to send interference measurement under a base station Signal sends interference measurement signal simultaneously without multiple UE.

The value done so is：When practical UL is dispatched, in some specific orthogonal resource, each base station one As in the case of also only can dispatch a UE and do UL transmission, therefore, more met based on the UE-UE disturbed conditions that this method identifies Practical application scene.

Base station scheduling portion or whole UE are sent on the orthogonal resource some or all of in one group of running time-frequency resource The interference measurement signal；

The behavior that base station scheduling UE sends the interference measurement signal in one group of running time-frequency resource can be divided into 2 classes： Real-Time Scheduling and semi-continuous scheduling.

When using Real-Time Scheduling mode, base station is dispatched UE in each scheduling unit and is being fallen in current scheduling unit The interference measurement signal is sent on the specific running time-frequency resource.Current scheduling unit may be the scheduling list of uplink and downlink mixing Member or pure descending scheduling unit；

When using semi-continuous scheduling mode, base station scheduling UE sends institute in multiple scheduling units on specific running time-frequency resource State interference measurement signal, wherein the scheduling unit can be base station uplink scheduling unit, the not used scheduling unit in base station, The not scheduled base station down scheduling units for doing downlink transfer of the UE and the UE are not scheduled and do on the base station of downlink transfer It is one or more in down mixing scheduling unit.

Particularly, base station is according to one or more in the factors such as UE processing capacities, power consumption, base station schedule, decision UE sends the interference measurement signal in which scheduling unit type.

Optionally, before base station determines, UE also needs to report the processing capacity of oneself to base station；Base station passes through RRC again Determination result is notified UE by signaling；

First base station and other base station (such as including second base station) interactive information, (such as by backhaul interfaces between station Logic communication interface protocol between the station of X2 or S1 etc) interact some information.

Follow-up behavior after confirming that surrounding is interfered there may be strong UE：

Mode one, single station solution

After base station confirms around the UE with the presence or absence of potential " UE-UE strong jammings to ", when follow-up one section default Between in section,

When base station determines that dispatching the UE does DL transmission, base station uses：Downlink signal, which is improved, for the UE emits work( Rate, using lower MCS, using one or more in the methods of lower TBS, doing downstream modulation processing to improve the UE When anti-interference ability.

Mode two, multistation coordinate scheme

After base station confirms around the UE with the presence or absence of potential " UE-UE strong jammings to ", the base station is further fixed Position " UE-UE strong jammings to "；

The embodiment of the present invention is directed in 5G NR technologies and has studied dynamic TDD technologies, that is, allows base station to be become according to business load Change dynamic and uses ascending-descending subframes.Under dynamic TDD application scenarios, when using existing LTE technological frames, the interference of UE to UE Signal is difficult to be accurately and identify, the interference source of UE to UE is more difficult to be accurately positioned.
