It can also include other in the communication system it should be understood that Figure 1A only exemplary rough schematic view for ease of understanding The network equipment can also include other terminal devices, not drawn in Figure 1A.

Within a wireless communication network, certain terminal may be subjected to the signal of neighboring community's terminal when being communicated with cell Interference, to influence the data receiver effect of the terminal.As shown in Figure 1B, cell A is serving cell, and cell B is interfered cell, User equipment (user equipment, UE) i.e. UE1 and UE2 in cell A coverage area can be led to the base station cell A Letter, user equipment (UE) 2, UE3 and UE4 in cell B coverage area can be communicated with the base station cell B.As can be seen that using Family equipment UE2 is both in the coverage area of cell A, also in the coverage area of cell B.For user equipment (UE) 1, cell A is serving cell, and cell B is interfered cell, and user equipment (UE) 1 will receive interfered cell B during communicating with cell A The interference of interior user equipment (UE) 2 and UE3, causes the communication quality of user equipment (UE) 1 impacted.It should be noted that user Equipment UE is referred to as terminal UE.

In order to improve communication quality, need to carry out interference elimination (interference cancel, IC) or AF panel (interference suppression, IS).Currently, in order to improve the effect of IC or IS, serving cell can pass through end The ratio judgement that the dominant interference that end UE is reported accounts for other interference obtains the interference strength of terminal UE, if the interference strength is bigger, Then position resource block (resource block, RB) of the disturbed terminal UE in serving cell notice interfered cell, so that interference Cell limits some scheduling informations of terminal UE in the interfered cell according to the position RB, to reduce in the interfered cell Interference of the terminal UE to the terminal UE in serving cell.This process is properly termed as the negotiation or cooperation of cell-level.

In existing this cell cooperative mode, can to generated in interfered cell resource block used in the terminal of interference into Row limitation.But interfered cell may only have several terminals to generate interference to serving cell in practice, this limitation can reduce dry It disturbs and interference is not generated to the terminal in serving cell in cell or interferes the performance of less terminal, and then influence entire The performance of communication system.Such as the terminal UE 4 in Figure 1B, terminal UE 4 can't generate interference to terminal UE 1, but terminal UE 4 can Can due to resource block limitation and have an impact.

The concrete reason for generating above-mentioned influence is that cell synchronization dispatches multiple terminals in same resource block, different Terminal using the terminal UE 2 in the different ports or wave beam, such as Figure 1B of resource block using a resource block Perhaps port 3 or wave beam 3 of 2 terminal UE 3 of wave beam using the resource block of port 2, terminal UE 4 is using the money The port 1 of source block or wave beam 1.Terminal UE 2 and terminal UE 3 can generate interference to serving cell, therefore the resource block can be limited System, but the performance of terminal UE 4 can also be similarly subjected to influence.

In this regard, the application provides a kind of communication means, this method can be recognized accurately in interfered cell which or which Terminal causes interference to serving cell, is precisely controlled, is prevented to the end not interfered to these terminals with realizing The limitation at end, and then guarantee the normal communication for the terminal that these are not interfered.It should be noted that terminal is eliminated or suppression The interference of system may include the interference occurred in minizone and cell.Terminal in serving cell is interfered, in serving cell Terminal receive data, but the terminal in neighboring community can be send data, be also possible to receive data.

It should be noted that the base station for being implemented as serving cell and being belonged to of serving cell, neighboring community it is specific It is embodied as the base station that neighboring community is belonged to.Below for ease of description, the base station that serving cell is belonged to can be known as taking Business cell, the base station that neighboring community is belonged to is known as neighboring community.The base station and neighboring community that serving cell is belonged to are belonged to Base station can be same base station, be also possible to different base station.If serving cell is multiple, the base that multiple serving cells are belonged to Station can be same base station, be also possible to different base station.If neighboring community be it is multiple, the base station that multiple neighboring communities are belonged to can To be same base station, it is also possible to different base station.

As shown in Fig. 2, communication means provided by the present application specifically comprises the following steps S201~S205.

S201: serving cell sends a notification message to target terminal, and wherein notification message is used to indicate target terminal progress Interference Detection and/or the configuration parameter reported.

Wherein, serving cell can determine which or which terminal into this serving cell sends a notification message first, For ease of description, these terminals can be known as target terminal.It is understood that target terminal is the terminal being disturbed, " target " in target terminal is used to distinguish the terminal being disturbed and interference source terminal.The method of determination of target terminal can have more Kind.In a kind of method of determination, terminal all in this serving cell can be determined as target terminal by serving cell.Another In kind method of determination, serving cell can obtain the performance parameter of each terminal in this serving cell, and performance parameter is selected to meet The terminal of certain condition is as target terminal.It is understood that performance parameter is parameter relevant to Interference Detection.For example, Performance parameter can be channel quality instruction (channel quality indication, CQI), if the CQI of terminal is lower than one Determine threshold value, then the terminal can be determined as target terminal；For another example, the terminal with IC IS ability can be determined as mesh Mark terminal.In order to make it easy to understand, being briefly described below to the terminal with IC IS ability.

As the processing capacity of terminal is stronger and stronger, it can integrate advanced receivers, to have IC IS energy Power.Such as especially for the terminal of WiMAX to family (wireless to the x, WTTX) type for, this Terminal Type With stronger processing capacity, power consumption, fever, volume etc. are not required for, can have stronger IC/IS energy completely Power.It should be noted that for that can eliminate or inhibit the advanced receivers of interference to be referred to as IC/IS receiver.It is right For IC/IS receiver, for different interference characteristics, different elimination or inhibitory effect can achieve.Such as it is capable and experienced Elimination relative to weak jamming or inhibitory effect are disturbed with regard to more preferable；For IC receiver, the low modulation and volume of interference signal High MCS of the code tactful (modulation and coding scheme, MCS) relative to interference signal, interferes the effect of elimination It becomes apparent from.For IS receiver, high order (rank) of the low-rank (rank) of interference signal relative to interference signal, interference disappears The effect removed just becomes apparent from.

It may include reporting configuration information in notification message, report configuration information to be used to indicate and be disturbed terminal and report interference Source information process need according to rule.Specifically, reporting configuration information may include being used to indicate one of the following or more The information of a content item: it above calls time, report condition, the interference maximum number reported, the channel class for whether needing reporting measurement Type.The information for reporting configuration information to be included can explicitly or implicitly indicate the above content item.It should be noted that Report information included in configuration information that can only indicate above section content item, remaining content item can in this case Know target terminal by other means, such as can be pre-configured in target terminal or target terminal Base station activly request belonged to serving cell etc..

Wherein, above call time can be periodically on calls time, be also possible to duration on call time, be also possible to It is injunctive to report.For example, serving cell can notify reporting for terminal periodic, then can calling time by, it is long to be set as the period The initial time spent and reported, such terminal can be determined according to the initial time and cycle length each periodic report when It carves, to periodically report.For another example, serving cell can notify terminal that duration reports within a certain period of time, then may be used It is set as start time point and termination time point to call time by, such terminal can be in two time points compositions It is persistently reported in period.For another example, serving cell terminal can be notified to report at some time point (for example agreement can specify that end It is indicated in the notification message that how long order that end receives serving cell transmission reports later or serving cell is sent Give the correct time quarter), then terminal can be reported and be reported constantly at this.

The condition for the interference that report condition is reported for limiting terminal.Terminal can detecte interference strength relevant information such as Interference strength or size, report condition can be the interference for reporting interference strength to be more than certain threshold value, also referred to as strong jamming, That is only the strongly disturbing interference information detected is just reported.

The interference maximum number reported is also referred to as the interference source maximum number that reports, and the interference reported for limiting terminal is most Big quantity, to reduce the expense of resource.The reason is that terminal needs to expend certain communication when reporting interference strength relevant information Resource, the communication resource spent by the more more then interference strength relevant informations of the amount of interference reported are more.

The channel type of reporting measurement whether is needed to be used to indicate terminal and report whether need to indicate interference institute's shadow when interference The type of loud communication channel.If necessary to the channel type of reporting measurement, then indicate that this is dry when terminal reports some interference Disturbing influenced communication channel is Physical Downlink Shared Channel (physical downlink shared channel, PDSCH) Or Physical Downlink Control Channel (physical downlink control channel, PDCCH).Wherein, PDCCH is carried Be PDSCH occupy resource location information, PDSCH use encoded information (such as MCS, rank etc.).Distinguish communication channel The reason of be that interference elimination method used in different communication channels will be different, the type of communication channel is reported to Serving cell can be such that serving cell is eliminated according to the type of communication channel to interference.

It should be noted that can also include the class that notice terminal carries out the communication channel of interference measurement in notification message Type is used to indicate terminal and which communication channel to carry out interference measurement to.The type of the communication channel of interference measurement may include One of PDCCH, PDSCH or a variety of.If the type for notifying terminal to carry out the communication channel of interference measurement is PDSCH, The interference that the PDSCH that terminal measurement serving cell is sent to the terminal is subject to；If terminal is notified to carry out the communication of interference measurement The type of channel is PDCCH, then the interference that the PDCCH that terminal measurement serving cell is sent to the terminal is subject to.

It can also include neighbor cell configuration information in notification message, neighbor cell configuration information may include being used to indicate in following One or more information: pilot signal is mapped to the type of the rule of the communication resource, the pilot signal of neighboring community.Wherein, Pilot signal be mapped to the communication resource rule may include: pilot signal port in neighboring community number, pilot signal Resource location information, pilot signal port differentiating method in it is any one or more.Pilot signal is mapped to the communication resource Rule be properly termed as: pilot signal is mapped to the pattern of the communication resource, alternatively, pilot signal is mapped to the side of the communication resource Formula.

It should be noted that the information that neighbor cell configuration information includes can explicitly or implicitly indicate the above content ?.Neighbor cell configuration information, which is used to indicate, is disturbed the pilot signal that terminal generates detection interference.It should be noted that neighbor cell configuration Included information can only indicate above section content item in information, remaining content item, which can be, in this case passes through Other modes know target terminal, for example, can be pre-configured in target terminal or target terminal to service it is small The base station activly request etc. that area is belonged to.The pilot signal that neighboring community uses is determined for neighboring community and generates interference Terminal used in port-mark, then can determine to generate interference by corresponding relationship between port-mark and terminal Terminal be which terminal.Specific description may refer to hereafter, herein and repeat no more.

The type of pilot signal is different, then the mode of target terminal generation pilot detection signal is also different, it is therefore desirable to will The type notification of pilot signal is to terminal.For example, the type of pilot signal may include demodulated reference signal (demodulation Reference signal, DMRS) or channel state information reference signals (channel-state information Reference signal, CSI-RS).DMRS is the reference signal for solving adjusting data, and CSI-RS is for measuring channel matter The reference signal of amount, they are two distinct types of pilot signals.It should be noted that pilot detection signal is by target end What end generated, for detect that terminal in interfered cell is sent or interfered cell sends to target terminal, there may be interference Pilot signal.That is, target terminal needs to generate an identical pilot tone letter to detect the interference of pilot signal Number.The pilot signal is properly termed as pilot detection signal for detecting.It should be noted that pilot signal here The channel type that type can also be used to indicate that target terminal carries out interference measurement indirectly (for example do not include in notification message It is mentioned-above notice terminal carry out interference measurement communication channel type), i.e., target terminal by the pilot signal into Row measurement is to reflect corresponding interference.

The number of pilot signal port in neighboring community is used to indicate the pilot signal which kind of form target terminal generates. The reason is that the port number divided in cell is different, then the corresponding pilot signal in each port is different.For example, in cell The port number of division is 6, then 1-6 corresponding pilot signal in port is pilot signal A1-A6；If the end divided in cell Mouth number is 8, then the corresponding pilot signal in port 1 is B1-B8.Therefore, serving cell needs to notify target terminal, adjacent small The port number in area is how many, and such target terminal is just it is known that need to generate pilot signal A1-A6 or B1-B8.Its In, pilot signal port can be referred to as port.

The resource location information of pilot signal refers specifically to position of the pilot signal in the communication resource, such as time domain position It sets, frequency domain position, code domain position etc..Wherein frequency domain position can refer to as unit of the resource block in the communication resource, or with More less than resource block granularity (such as resource element (resource element, RE) either the half of resource block or A quarter) it is unit, or can be specially with part resource bandwidth (bandwidth part, BWP) for unit, one BWP can be by multiple resource blocks or multiple granularmetric compositions more less than resource block.It should be noted that the resource-niche of pilot signal Confidence breath can be referred to as position or communication resource position.

The port differentiating method of pilot signal for notify the pilot signal port of target terminal neighboring community with communicate provide Corresponding relationship between source position.For example, port differentiating method may include during orthogonal frequency domain, time domain orthogonal, code domain are orthogonal The combination of any one or more, frequency domain is orthogonal and the port of time domain orthogonal representation neighboring community is with communication resource position One-to-one relationship, the pilot signal port and communication resource position of code domain orthogonal representation neighboring community are many-to-one relationships, Many-to-one relationship refers specifically to, and identical communication resource position corresponds to multiple and different pilot signal ports.Why will Corresponding relationship be sent to target terminal the reason is that, the pilot detection signal that target terminal generates at each communication resource position Number is different.Because pilot detection signal to be generated and pilot signal port are one-to-one relationship, communication resource position Corresponding relationship between pilot signal port can indicate the corresponding relationship between communication resource position and pilot detection signal. Therefore, if the corresponding relationship of port and communication resource position is one-to-one relationship, target terminal is provided in a communication It only needs to generate a pilot detection signal at source position, be closed if pilot signal port is corresponding with communication resource position System is many-to-one relationship, then target terminal needs to generate multiple pilot detection signals at a communication resource position.Separately Outside, configuration information can also include some information needed for generating pilot signal sequence.It generates one needed for pilot signal sequence Some parameters needed for a little information refer to generation pilot signal sequence, such as the mark of neighboring community, scrambling code number (for example, n_SCID∈ { 0,1 }), scrambling code identification corresponding to scrambling code number (for example,)。

S202: target terminal detects the interference being subject to according to notification message, and determines the interference source information of interference.

Wherein, target terminal measures interference according to the instruction of notification message.It is preceding to have addressed, in order to measure Need to generate pilot detection signal, therefore, target terminal is first according to the class of the pilot signal in notification message before interference measurement Type determines the type of pilot detection signal to be generated, and according to the number of neighboring community's middle port in notification message, determines The form of pilot detection signal to be generated.For example, the type of the pilot signal in notification message is DMRS, then it is to be generated to lead The type of frequency detection signal is similarly DMRS；The number of neighboring community's middle port is 6, then can determine pilot tone inspection to be generated The form for surveying signal is A1-A6 form.It should be noted that the type of the pilot signal in communication information also may include more Kind, target terminal determines to detect which type of interference signal according to the signal intelligence of itself, then generates leading for this type Frequency detection signal.

After the type and form that determine pilot detection signal, each pilot signal can be generated.If serving cell is sent out In the notification message sent, the corresponding relationship between port and communication resource position is many-one, then in each communication resource position The place of setting can generate the corresponding pilot detection signal in multiple ports corresponding to the communication resource position.It should be noted that pilot tone It detects and needs input signal parameter in the generating mode of signal, signal parameter can derive from neighbor cell configuration parameter, may include The type of pilot signal, the number of neighboring community's middle port, the resource location information of pilot signal, pilot signal port, small One or more in area's mark, signal parameter also may be embodied in the notification message of serving cell transmission.

It can also include the resource location information of pilot signal in notification message, therefore after generation pilot detection signal Pilot detection signal to be compared with the pilot signal at the resource location information, if some pilot tone to be detected generated Signal is identical as the pilot signal at the resource location information, then can determine that the pilot signal at the resource location information is The pilot detection signal.For ease of description, the pilot signal determined can be known as target pilot signal.

It should be noted that the identical expression target terminal of two pilot signals receives interference.In addition, being wrapped in notification message The communication resource position contained be it is multiple, if target terminal detects identical pilot signal at certain resource location information, Illustrate that target terminal receives interference at the communication resource position, if target terminal is not examined at certain resource location information Identical pilot signal is measured, then illustrates that target terminal is not interfered at the communication resource position.As it can be seen that target terminal The communication resource position being really interfered can be detected in multiple communication resource positions, for ease of description, can be incited somebody to action The communication resource position being interfered is known as target communications resources position.

After target terminal determines pilot signal, this can be determined according to the corresponding relationship between pilot signal and port The corresponding port of pilot signal.For example, the pilot signal that target terminal determines is A4, according to pair between pilot signal and port It should be related to A4-port4 it is found that the corresponding port-for-port 4 of pilot signal A4.

It should be noted that the corresponding relationship between pilot signal and port can be and be led in neighboring community and terminal Specified in the agreement of letter, the corresponding relationship in communication protocol can be sent to target terminal by serving cell.Alternatively, logical The corresponding relationship in letter agreement can also not be sent to target terminal, but the pilot signal that target terminal will test out is sent out The serving cell given is determined corresponding to the pilot signal by serving cell according to pilot signal and the corresponding relationship Port, then the corresponding port identification information in the port is sent to neighboring community.

By above description it is found that target terminal can determine the terminal interfered in neighboring community to target terminal Used pilot signal port.Port can indicate that port-mark is an information of interference source information with port-mark.It is dry Disturbing source information may include port identification information, and port identification information is used to indicate the corresponding port-mark of interference source.Port mark Knowing information may include the corresponding CSI-RS port information of interference, PDCCH DMRS port information or the PDSCH detected It is one or more in DMRS port information etc..

It should be noted that port-mark can also include the mark of neighboring community, for indicating suffered by serving cell The interference arrived from neighboring community be which cell.The mark of neighboring community may include neighboring community actual identification or The index of neighboring community identifies.Specifically, before determining interference source information, serving cell can prenotice target terminal phase Adjacent cell identification list, the corresponding index of actual identification and actual identification in the list comprising each neighboring community identify.Or Person in another implementation, only can explicitly carry the actual identification of neighboring community in neighboring community's identification list, practical Identifying corresponding index mark can not carry explicitly in neighboring community's identification list, and index mark, which can be, passes through reality Identify what the sequence in neighboring community's identification list was determined.After target terminal receives neighboring community's identification list, just The corresponding index mark of the actual identification can be searched in the list according to the actual identification of neighboring community, and index is identified Mark as neighboring community is reported.Since the data volume of the index mark of neighboring community is less than the practical mark of neighboring community Know, therefore target terminal can be reduced using index mark and report the communication resource used in interference source information.

In addition, can also include the resource information where interference time information and interference in interference source information.Port-mark, It is dry that resource information where interfering time information and interference is used to determine that interference source generates target terminal in neighboring community The terminal disturbed, specific method of determination do not repeat herein referring to following step S205.

Wherein, what interference time information indicated is that information can be with when target terminal detects interference at the time of interference occurs Record interference time information, and serving cell is uploaded to using interference time information as an information of interference source information.It needs Illustrate, interference time information can also and not be included in the interference source information that target terminal uploads, but can be by servicing Cell determines interference time information.Specifically, it when serving cell receives the interference source information that target terminal reports, can obtain The interference source information reports the moment, and what serving cell can have a record interference source information in advance reports moment and interference moment letter Corresponding relationship (for example, agreement defines the corresponding relationship reported between moment and interference time information) between breath, takes in this way Business cell obtain interference source information report the moment after, interference time information can be determined according to the corresponding relationship, and should Interference time information, which is included in interference source information, is sent to neighboring community.Alternatively, serving cell is sent to the dry of neighboring community Disturbing can also not include interference time information in source information, interfere time information but determined by neighboring community itself 's.Specifically, it can negotiate between neighboring community and serving cell at the time of provisioning service cell sends interference source information and do The corresponding relationship between time information is disturbed, come really at the time of such neighboring community can send interference source information according to serving cell Surely time information is interfered；Or neighboring community with the clock of serving cell be it is synchronous, then between neighboring community and serving cell At the time of information be it is synchronous, neighboring community can according to serving cell send interference source information at the time of and interference source believe The corresponding relationship of breath reported between moment and interference time information, determines interference time information.

There is the communication resource position interfered in resource information where interfering detected by target terminal.Wherein, it does Resource information where disturbing can be as unit of resource block, perhaps with granularity more less than resource block (such as RE or resource block Half perhaps a quarter) be unit or can be specially as unit of BWP, a BWP can be by multiple resource blocks Or multiple granularmetric compositions more less than resource block.Optionally, the resource information where interfering is resource block RB information.For mesh It marks for terminal, which the resource block RB that the resource block information where interfering really is interfered is.Target terminal itself by The resource block RB information of interference can indicate the resource block RB that neighboring community interferes, and the two is one-to-one relationship.Mesh Mark terminal determine the mode of resource block RB that is disturbed can there are many.In a kind of method of determination, target terminal itself Where useful signal in resource block, whether detection neighboring community has sent pilot signal in corresponding resource block.If detection To pilot signal, then the resource block RB where target terminal determines the pilot signal receives interference.In another method of determination In, for target terminal in the corresponding all resource blocks of serving cell whole bandwidth, whether detection neighboring community has sent pilot tone letter Number, if detecting pilot signal, the resource block RB where target terminal determines the pilot signal receives interference.Wherein It should be noted that the corresponding all resource blocks of serving cell whole bandwidth can be and inform target terminal by notification message 's.In another method of determination, target terminal detects adjacent small in the corresponding all resource blocks of neighboring community's whole bandwidth Whether area has sent pilot signal, if detecting pilot signal, target terminal determines the resource where the pilot signal Block RB receives interference.Wherein it should be noted that whole bandwidth corresponding all resource blocks in neighboring community's can be by logical Know that message informs target terminal.

It should be noted that the resource block information where interference can not be included in target terminal and be sent to serving cell Interference source information in, but can be determined by serving cell itself.Specifically, the resource block of target terminal is by servicing Cell distribution, therefore serving cell can assign them to the resource block of target terminal as the resource block where interference.But Be resource block that this kind of mode is determined be it is multiple, finally determining interference source may be not exactly accurate.In addition, service is small Area can negotiate target terminal time segment from target terminal and detect the interference that different resource blocks are subject to, such as the moment 1 is detected Be resource block 1-5, that the moment 2 is detected is resource block 6-10, and such serving cell can be determined according to interference time information Interference where resource block which is specifically.After serving cell determines the resource block where interference, by resource block information packet It is contained in the interference source information for being sent to neighboring community.Alternatively, can not be true by serving cell in another implementation It is fixed, but by neighboring community according to the pilot frequency port information and neighboring community carried in interference time information, interference source information History scheduling information is determined uses corresponding pilot frequency port in which resource block of corresponding interference time information, to obtain Resource block information where interfering.

Target terminal believes the resource block information where port identification information, interference time information and interference as interference source Three in breath, can also include other optional information in certain interference source information.It should be noted that interference source information packet Port identification information is included, but time information and the resource block information at interference place is interfered to be sent to serving cell as target terminal Interference source information in option, can be not comprised in the interference source information.Interfere time information and/or interference place Resource block information can be determined by serving cell, by serving cell by this two information be included in be sent to neighboring community Interference source information in.Or in application scenes, serving cell is in the interference source information for being sent to neighboring community It can not include this or two information, but this or two information are determined by neighboring community oneself.Specifically Ground, if neighboring community is synchronous with the clock of serving cell, neighboring community can determine interference institute according to interference time information Resource block information.

S203: target terminal reports interference source information to serving cell.

Wherein, target terminal, can also be obtained from the port that body is interfered after detecting interference source information, and establishes The corresponding relationship for being disturbed port and interference source information of itself reports the corresponding relationship when reporting interference source information, in this way After serving cell or neighboring community receive the interference source information that target terminal reports, it can determine that the interference source information is Interference is caused to which terminal.In order to briefly explain, corresponding relationship can be indicated are as follows: interference source information-[port].

Such as it is assumed that the port that target terminal uses includes port 0, the corresponding relationship reported are as follows: the corresponding interference in port 0 Source information is the port cell 0+ 1, can be determined by the corresponding relationship, the corresponding terminal in port 0 receives the end in cell 0 It is interfered caused by 1 corresponding terminal of mouth.Another corresponding relationship that target terminal reports is assumed again are as follows: the corresponding interference in port 1 Source information is the port cell 1+ 0, can be determined by the corresponding relationship, the corresponding terminal in port 1 receives the end in cell 1 It is interfered caused by 0 corresponding terminal of mouth.It should be noted that the port that above-mentioned target terminal uses could alternatively be code word (codeword) or other can with terminal have corresponding relationship resource information.

It should be noted that report to service small for the noisy interference source information of institute that target terminal can will test Area.In another implementation, after target terminal detects interference, strong jamming is determined in the interference detected, and The corresponding interference source information of strong jamming is sent to serving cell.That is, the interference source information of weak jamming can't be sent out It send to serving cell, sends interference source information bring resource consumption the purpose for the arrangement is that reducing.

After target terminal detects interference source information, the relevant information of the interference strength of interference source generation can also be detected, Determine that interference is strong jamming or weak jamming according to interference strength relevant information.If the agreement between serving cell and neighboring community Middle regulation, the strong jamming only generated to neighboring community are handled, then serving cell can only notice neighboring community's strong jamming pair The interference source information answered, so that neighboring community is only handled the corresponding interference source information of strong jamming.

It is understood that in order to realize above-mentioned processing, serving cell can determine the corresponding interference source letter of strong jamming Breath, specific method of determination can there are many: for example target terminal selects interference source information before reporting interference source information It selects, only reports the corresponding interference source information of strong jamming, can to go out this dry as long as such serving cell receives interference source information Disturbing source information is the corresponding interference source information of strong jamming；For another example target terminal is when reporting interference source information together by interference strength Relevant information is reported to serving cell, and serving cell judges that interference is strong jamming or weak does according to interference strength relevant information It disturbs, and then can determine the corresponding interference source information of strong jamming.

Wherein, if determining strong jamming by target terminal, target terminal determine strongly disturbing mode can there are many.

In a kind of method of determination, if the receiver of target terminal is non-advanced receivers, target terminal is according to itself The channel relevancy of signal and interference channel come judge interference for strong jamming or weak jamming.For example, if target terminal from The channel relevancy of body signal and interference channel reaches certain requirement, then the interference of the interference channel is known as strong jamming；It is on the contrary It is determined as weak jamming.

In another method of determination, if the receiver of target terminal is non-advanced receivers, target terminal determines dry The size of power is disturbed, if the size of jamming power reaches certain threshold value, which is determined as strong jamming；Otherwise it is determined as Weak jamming.

In another method of determination, if the receiver of target terminal is advanced receivers, target terminal can be obtained Advanced receivers determine that interference is strong jamming or weak to the inhibition situation of detected interference, and according to AF panel situation Interference.Wherein AF panel situation is referred to as interference suppressioning effect, interference eradicating efficacy or interference and eliminates situation.Specifically Ground, target terminal obtain advanced receivers to Signal to Interference plus Noise Ratio (the signal to before AF panel Interference plus noise ratio, SINR) and AF panel after Signal to Interference plus Noise Ratio, compare The difference of two SINR.If difference is less than certain threshold value and jamming power and reaches certain threshold value, which is determined as Strong jamming；Otherwise referred to as weak jamming.Wherein, the calculation of the SINR after the SINR and AF panel before AF panel It is as follows.Target terminal estimates the data association message of the interference of neighboring community's generation, such as modulation and coding strategy (modulation And coding scheme, MCS), order, therefore data association message be properly termed as interference generation parameter.Target terminal also needs The channel information of interference is obtained, and then can be calculated dry according to the generation parameter of interference and the channel information of interference The approximate signal for the data-signal disturbed.Target terminal obtains the total interference data signal received, uses the data-signal of itself The SINR before AF panel is obtained divided by total interference data signal.In addition, target terminal subtracts in total interference data signal The data-signal of interference obtains the data-signal after AF panel, using the data-signal of itself divided by AF panel after Data-signal obtain the SINR after AF panel.

In another method of determination, target terminal judges whether the decoding of the data in own channel is correct, if correct It determines that interference is strong jamming, otherwise is determined as weak jamming.

It is to determine that interference is strong jamming or weak jamming by target terminal, and only needing will be capable and experienced in implementation above mode It disturbs corresponding interference source information and is sent to serving cell.In another implementation, target terminal can also be by interference strength Relevant information is sent to serving cell, judges the interference for strong jamming or weak according to interference strength relevant information by serving cell Interference.Wherein for judging the interference for strong jamming or weak jamming, judgment mode can be above-mentioned interference strength relevant information Target terminal judges interference for any one in strong jamming or weak jamming.It should be noted that in the first implementation, Target terminal need to only upload the corresponding interference source information of strong jamming, but in this kind of implementation, target terminal itself It can not know out to interfere as strong jamming or weak jamming, target terminal is by the corresponding interference strength relevant information of interference source information It is also sent to serving cell.

It should be noted that when SINR after SINR and AF panel before calculating AF panel, it can be not Target terminal is confined to be calculated when receiving the data that serving cell is sent.If between target terminal and serving cell not It is communicated, some analogue datas can be generated, the data that these analogue datas are sent as serving cell to target terminal, According to the SINR after the SINR and AF panel before these data calculating AF panel.This is because neighboring community with When terminal in neighboring community is communicated, serving cell may and it is non-concurrent communicated with target terminal, therefore target end End is not interfered actually, but as long as Communication Jamming can produce the two simultaneously, therefore target terminal can be made to simulate Communication process, the interference that this process detects can be used as the interference during practical communication.

It should be noted that if target terminal needs to report interference source information and interference strength relevant information, this two letters Breath can report simultaneously, can also be different and report constantly.Reporting schemes are that can pass through Physical Uplink Control Channel (physical Uplink control channel, PUCCH) it reports, Physical Uplink Shared Channel (physical uplink can also be passed through Shared channel, PUSCH) it reports.If being reported by PUSCH and by media access control control element (media Access control control element, MAC CE) it carries when reporting interference source information, it can be carried by MAC CE dry The measurement time information disturbed such as slot s lot or/and System Frame Number (system frame number, SFN), measurement moment letter Breath is the interference time information in interference source information.If it should be noted that illustrating target terminal not in above-mentioned steps S202 Interference time information explicitly is reported, then moment letter can be interfered constantly to determine according to reporting for interference source information by serving cell Breath is the corresponding relationship of interference source information reported between moment and interference time information based on when serving cell determines. At the time of wherein interference generates, that is, the interference measurement moment, if reporting interference, PUCCH or PUSCH by PUCCH or PUSCH Sending instant or report between moment and interference measurement moment that there are regular hour corresponding relationship such as fixed intervals are certain Duration, such serving cell, can be right according to this after receiving the interference source information reported by PDCCH or PUSCH It should be related to and determine interference time information.

It should be noted that if target terminal does not report interference strength relevant information, then serving cell can be according to mesh The CQI information that reports of mark terminal judges whether interference is that (for example CQI is lower than certain threshold value, it may be considered that being to strong jamming Strong jamming, otherwise it is assumed that being weak jamming), the signal strength (reference that can also be also reported simultaneously according to target terminal Signal received power, RSRP) come judge interference whether be strong jamming (for example, if CQI lower than certain threshold value and RSRP is higher than certain thresholding, then it is assumed that is strong jamming, otherwise it is assumed that being weak jamming).

It is just carried out if regulation target terminal gives the correct time on having reception data in the communication protocol of target terminal and serving cell Interference source information is reported, then the confirmation or not confirmation signal that interference source information can receive data with target terminal feeding back downlink It reports together.

S204: serving cell sends interference source information to neighboring community.

Wherein, if including port-mark, interference time information and interference in the interference source information that target terminal reports The resource block information at place, then interference source information can be transmitted to neighboring community by serving cell.If in interference source information simultaneously Non- includes above-mentioned three information, then the relevant information of the interference source information reported by serving cell according to target terminal is needed to determine Above-mentioned three information out, then above-mentioned three information is transmitted to neighboring community.Wherein it should be noted that the phase of interference source information Information is closed to be used to determine that interference source information, the relevant information of interference source information have specifically in above-mentioned steps for serving cell It is bright, illustrate briefly below.As it can be seen that if target terminal upload be interference source information relevant information, serving cell can be with Pre-processing is carried out for the relevant information of interference source information, to determine interference source information, specific processing may include following Several.

Preceding to have addressed, the interference source information that target terminal reports can have corresponding relationship between neighboring community, then take Interference source information can be sent to neighboring community corresponding with the interference source information according to the corresponding relationship by business cell.It is dry It disturbs in source information if including the index mark of neighboring community, the index of serving cell can be identified and be converted by neighboring community For the actual identification of neighboring community.If there is no adjacent area mark in interference source information, serving cell oneself processing is given.Such as Serving cell may notify interference source information all neighboring communities, and only accuracy is relatively low in this case.

Preceding to have addressed, target terminal can report interference strength relevant information, and serving cell receives interference strength correlation After information, strong jamming can be determined according to interference strength relevant information, and then be to the interference source information that neighboring community is sent The corresponding interference source information of strong jamming.

It should be noted that interference source information has the corresponding relationship with target terminal, corresponding relationship is for indicating some Which the interference source information that target terminal is subject to is.Serving cell, can be right before sending interference source information to neighboring community Target terminal and/or interference source information grouping.Serving cell can send the corresponding relationship of interference source information and target terminal To neighboring community, sends, can be removed in such a way that target terminal and/or interference source information are grouped when sending the corresponding relationship Redundant data, to reduce the consuming of the communication resource.

For example assume that the corresponding interference source information of three target terminals is identical in serving cell, then it can be three targets Terminal corresponds to identical interference source information as a target terminal group, the target terminal group.Serving cell is sent to phase in this way It can't include corresponding three corresponding relationships of three target terminals in the corresponding relationship of adjacent cell, but target terminal One corresponding relationship of group and interference source information, to reduce the consumption of the communication resource.

For another example assume that the interference source information for three interference that some target terminal is subject to is identical, then by three interference source letters It is used as an interference source information group after breath removal redundancy, which corresponds to identical target terminal.It services so small Area is sent in the corresponding relationship of neighboring community, can't include three interference source informations, but target terminal and an interference The corresponding relationship of source information group, to reduce the consumption of the communication resource.It should be noted that serving cell can also be according to interference A part of content in source information is identical to be grouped target terminal and/or interference source information.For example three are assumed in serving cell The pilot frequency port of the corresponding interference source information of target terminal is identical, then can be using three target terminals as a target terminal Group, the target terminal group correspond to the pilot frequency port in identical interference source information.Serving cell is sent to neighboring community in this way It can't include corresponding three corresponding relationships of three target terminals in corresponding relationship, but target terminal group and interference A corresponding relationship (the different information of other in interference source information carries respectively again) for pilot frequency port in source information, to subtract The consumption of the communication resource is lacked.For another example assume the pilot frequency port in the interference source information for three interference that some target terminal is subject to It is identical, then it will be used as an interference source information group after three interference source information removal redundancies, which corresponds to phase Same target terminal.Serving cell is sent in the corresponding relationship of neighboring community in this way, can't include three interference source informations Pilot frequency port, but the corresponding relationship of target terminal and an interference source information group, to reduce the consumption of the communication resource.

S205: neighboring community determines the corresponding interference source of interference source information according to schedule history message and interference source information.

Wherein, neighboring community can recorde itself the schedule history message to the terminal of neighboring community service, and scheduling is gone through What is recorded in history message is the corresponding relationship between moment, port, resource block and terminal.Specifically, neighboring community is to end When end is scheduled, different moments, same resource block may serve different terminals, therefore can be used in interference source information Interference time information at the time of determine to interfere；Further, synchronization neighboring community may use multiple and different Port different terminals are scheduled, therefore determine interfere time information after, can further use in interference source information Port-mark, the port that interferes is determined in multiple ports；Under synchronization same port, different resource block letters Breath may serve different terminals, therefore after determining interference port, can further use the interference in interference source information Resource block information where source determines the resource block interfered in multiple resource blocks, and then according in schedule history information Terminal corresponding to the resource block determined is determined as interference source by the corresponding relationship between resource block and terminal.Assuming that interference Source is interfered stable caused by disturbed terminal, and being stabilized interference can recorde in history scheduling information, then does It disturbs and may include the mark for being disturbed terminal in source information, then according to history scheduling information and be disturbed the mark of terminal, just It can determine interference source.Alternatively, may include interference time information in interference source information and be disturbed the mark of terminal, then According to history scheduling information and it is disturbed the mark of terminal, can determine interference source.

In order to make it easy to understand, being illustrated in conjunction with Fig. 3 to above process determination.As shown in figure 3, dry in interference source information Time information is disturbed as the coordinate value in moment reference axis, multiple ports and resource can be determined according to the moment coordinate value Block；Further, the port-mark in interference source information is as the coordinate value in the reference axis of port, and according to the port, coordinate value can To determine some port in multiple ports, multiple resource blocks are corresponding under the port.The entire frequency domain bandwidth of one cell Multiple resource blocks can be divided into, therefore multiple resource blocks that resource block 0 arrives resource block N are distributed on frequency coordinate, further Ground, the resource block information where interference in interference source information are believed as the coordinate value on frequency coordinate axis according to the resource block Breath can determine the resource block interfered in multiple resource blocks.As shown in Figure 3, it is assumed that the resource block determined is circle The resource block that wire frame is chosen.And then corresponding terminal is determined as interference source in schedule history information by the resource block.

As it can be seen that the corresponding relationship between moment, port, resource block and terminal can be expressed as [moment, port, resource Block]-terminal, that is to say, which can just uniquely determine out interference source using three moment, port and resource block information is at end End.It should be noted that first determining time information according to sequential write in above-mentioned determination step, then determine port information, most Resource block information is determined afterwards, but determining sequencing is not limited to above-mentioned sequential write in practical applications, it can be with Other sequences, as long as determining terminal using three information.

It should be noted that in order to further simplify neighboring community to the determination process of interference source, in interference source to clothes After interference caused by cell of being engaged in is relatively stable, record the interference source being disturbed in terminal and neighboring community in serving cell it Between corresponding relationship, that is to say, which terminal can interfere which terminal relatively stable, then can recorde two Corresponding relationship between person, as long as terminal disturbed in this way is interfered, serving cell issues the mark of disturbed terminal Neighboring community, neighboring community can find according to above-mentioned corresponding relationship and be disturbed the terminal that terminal interferes to this and be Which or which terminal.It should be noted that interference source and being disturbed in the corresponding relationship between terminal both can also record Between interference size, as shown in table 1 below.Assuming that the cell 1 in table 1 is serving cell, cell 2 is neighboring community.

Table 1

Interfere size	Cell 1- terminal 1	Cell 1- terminal 2	Cell 1- terminal 3
				Cell 2- terminal 1	Nothing	0.3	0.6
Cell 2- terminal 2	0.2	Nothing	0.1
				Cell 2- terminal 3	0.8	0.5	Nothing

From the above technical scheme, this application provides a kind of communication means, in this method by serving cell by The terminal of interference detects the interference that itself is subject to, and terminal or serving cell determine interference source letter according to testing result Interference source information is sent to neighboring community by breath, serving cell, and neighboring community is true according to schedule history information and interference source information The interference source interfered is made, so as to realize the accurate inhibition to the interference source, is not influencing other terminals communication matter In the case where amount, reduce influence of the interference source to terminal in serving cell.

In the application, neighboring community can also be further realized in addition to can accurately determine interference source information to interference The inhibition in source.As shown in figure 4, can also include the following steps S206 on the basis of the step of above-mentioned Fig. 2 is included.

S206: neighboring community is interfered caused by interference source to be inhibited.

Wherein, in a kind of implementation, serving cell can send the parameter for eliminating interference to neighboring community, so that Neighboring community can interfere caused by interference source according to these parameters when dispatching interference source and eliminate.It needs to illustrate It is that elimination here may be considered inhibition movement, and not result describes, that is to say, that reducing interference can not necessarily can Enough completely eliminate.Inhibition is by interference reduction, as long as the suppressor mode that can reach the effect may be embodied in this technology In the achievable mode of scheme.Parameter for inhibiting interference may include two classes, and one kind is the i.e. disturbed terminal of target terminal Messaging parameter, such messaging parameter may include but be not limited to it is following several, as port, wave beam, physical down control letter Road controls resource collection etc.；One kind is the messaging parameter that the terminal interfered to interference source is recommended, such messaging parameter can With including but not limited to following several, as port, wave beam, Physical Downlink Control Channel control resource collection (mainly physics The corresponding running time-frequency resource information of down control channel), modulation is with coding strategy, order, power etc..

It should be noted that serving cell sends first kind messaging parameter, that is, target terminal messaging parameter to neighboring community Afterwards, neighboring community needs to determine the destinations traffic parameter of the interference caused by being able to suppress interference source according to the messaging parameter, But serving cell to neighboring community send the second class messaging parameter be recommend messaging parameter after, neighboring community can directly by The messaging parameter of recommendation is as destinations traffic parameter, to simplify neighboring community to the treatment process of interference source.

For example, serving cell can hold consultation between neighboring community, by can't be to target terminal in neighboring community Target port or object beam are sent to adjacent by a port or wave beam interfered as target port or object beam Cell, so that port used in interference source or wave beam are replaced with the target port or wave beam by neighboring community.That is, phase Adjacent cell and serving cell can hold consultation for interference source and disturbed terminal and dispatch running time-frequency resource, so that disturbed terminal It is scheduled and is staggered with interference source, avoid interfering by being not take up identical resource.

For another example, serving cell can recommend modulation and coding strategy, order, power etc. to neighboring community, so that serving cell The parameter for directly using these to recommend when dispatching interference source, to inhibit to interfere caused by interference.

In addition to above AF panel mode, other existing AF panel modes can also be used, such as to interference source The PDCCH that uses carry out for example higher control channel unit (control channel element, CCE) of specially treated or Transmitting diversity.

It should be noted that in order to improve the performance of interference source, when disturbed terminal such as target terminal is without business, clothes Business cell can notify neighboring community to be disturbed terminal without business, and neighboring community can reduce or release after obtaining the information Inhibition to interference source.

It is to be inhibited by neighboring community to interference in embodiment shown in figure 4 above.In another implementation, The interference that target terminal is subject to can be inhibited by serving cell.As shown in figure 5, the step base for being included in above-mentioned Fig. 2 On plinth, it can also include the following steps S506~S509.

S506: neighboring community determines that interference source generates the messaging parameter that interference signal uses.

Wherein, messaging parameter specifically includes: pilot tone is mapped to the mode of the communication resource and the coding parameter of interference signal, Can specifically include but be not limited to any one or more in following items: MCS, port, cell-radio network are temporarily marked Know (cell radio network temporary identifier, C-RNTI), frame structure, the corresponding order instruction of PDSCH, The resource block information of PDSCH DMRS information, occupancy.Need to estimate interference source data letter when detecting interference in the step S202 of Fig. 2 Number, the messaging parameter in this step can be used when estimating.

Wherein, messaging parameter can be sent to target terminal by serving cell by neighboring community, and target terminal can benefit With in messaging parameter MCS and port information estimate out interference data signal (such as PDSCH).In addition, C-RNTI can also be for The PDCCH that target terminal detection neighboring community is sent to interference source, to estimate interference data signal.

Frame structure may include (selfcontain) uplink and downlink distribution self-contained in each subframe, 2 stage downlinks control letter Cease (2-stage Downlink control information, 2-stage DCI) format, code word mapping mode, PDCCH CORESET configuration etc..

Wherein, what what the distribution of self-contained uplink and downlink indicated be which symbol indicates is downlink signal, what which symbol indicated It is uplink signal, which signal is that downlink turns the corresponding gap of uplink.Self-contained uplink and downlink distribution letter can be used in target terminal Cease estimate out which resource be by neighboring community downlink signal interfere, uplink signal of which resource by neighboring community Interference.

2-stage DCI refers to whether interference source uses 2-stage DCI mode, and 2-stage DCI is that downlink is controlled Information is assigned as two parts, and a part is placed in the region PDCCH CORESET, and a part is placed on data area.Code word mapping side Formula may include: that the relationship of downlink resource, e.g. layer to frequency to moment or layer are mapped to using several code words and code word Then being carved into frequency or moment to frequency arrives moment etc. to layer or frequency to layer.It is this mapping precedence relationship indicate be First the resource of which dimension is taken the resource for going to occupy other dimensions again later, wherein the relationship between moment, frequency and layer can With reference to shown in Fig. 3.It should be noted that layer here, which refers to, can transmit more parts of data on same running time-frequency resource.2-stage DCI can estimate out the interference which resource is controlled information by neighboring community for target terminal, which resource is by adjacent small The interference of area's data channel.

The effect of code word mapping mode is the data information for preferably decoding interference source for target terminal, thus more quasi- Interference source signal really is recovered, the interference eradicating efficacy after subtracting the interference source signal in total interference is more preferable.

Time-domain resource and frequency domain resource position, effect of the PDCCH CORESET configuration including PDCCH are for target terminal The location of the PDCCH of interference source is specified, convenient for the PDCCH of target terminal detection interference source, to obtain the correlation of PDCCH Information and then AF panel.

PDSCH DMRS information may include preceding to DMRS configuration information, additional DMRS configuration etc..PDSCH DMRS information Effect be in order to target terminal confirmation interference source PDSCH DMRS resource information, convenient for target terminal carry out PDSCH channel Estimation, to preferably eliminate or inhibit interference source PDSCH.Wherein the configuration of forward direction DMRS configuration information includes the number of DMRS port Mesh, the location information of DMRS, DMRS port differentiating method.Additional DMRS configuration refers to PDSCH in forward direction DMRS configuration information The position of instruction has except DMRS pilot tone, also there is additional DMRS in other positions, for preferably carrying out channel estimation.

It should be noted that interference source, which generates in the messaging parameter that interference signal uses, may include some messaging parameter Multiple values, such as multiple possible values of MCS.

S507: neighboring community sends the messaging parameter that interference signal uses to serving cell.

Wherein, neighboring community can send messaging parameter to serving cell by scrambled PDCCH.

It should be noted that neighboring community can be according to the target terminal group of serving cell or/and the interference of neighboring community Source group sends the messaging parameter that interference signal uses, to reduce the consuming of the communication resource.

Specifically, there is corresponding relationship, corresponding relationship indicates between the messaging parameter and target terminal that interference signal uses Which target terminal the messaging parameter that interference signal uses needs to be sent to.Neighboring community is sending messaging parameter to serving cell Before, target terminal and/or messaging parameter can be grouped.It specifically, can be using identical messaging parameter as one Set of communication parameters, and then the corresponding relationship of target terminal and set of communication parameters is sent to serving cell；Alternatively, can will be identical Target terminal as a target terminal group, and then by the corresponding relationship of messaging parameter and target terminal group be sent to service it is small Area；Or can be using multiple target terminals as a target terminal group, multiple target terminal is having the same multiple or one A interference source, and then using this multiple or interference source as an interference source group, and then by target terminal group and interference source group And the corresponding relationship of corresponding messaging parameter is sent to serving cell.This mode can reduce redundant data, to reduce logical Believe the consuming of resource.

S508: serving cell sends the messaging parameter that interference signal uses to target terminal.

Wherein, the messaging parameter of serving cell notice target terminal interference signal, it is therefore an objective to be carried out more convenient for target terminal Good AF panel, specific process of inhibition are detailed in step S509.

It should be noted that may be multiple, but the processing energy of target terminal to the interference source that target terminal interferes Power may be limited, can only eliminate the interference of limited quantity, therefore target terminal may notify serving cell certainly by radio open The processing capacity of body, such as notice serving cell itself can eliminate several layers of interference or several interference sources.Serving cell obtains After knowing this message, the messaging parameter of interference signal compatible with its ability is sent to the property of can choose to target terminal, with Make target terminal that only these interference signals be eliminated or be inhibited.

Serving cell can determine the interference source that the target terminal is capable of handling according to the processing capacity of target terminal, and Using the corresponding messaging parameter of these interference sources as set of communication parameters, set of communication parameters is sent to target terminal, so that target Terminal is only eliminated or is inhibited to interference according to set of communication parameters.Alternatively, serving cell can also notify that target is whole Hold corresponding interference source information.

S509: the messaging parameter that target terminal is used according to interference signal inhibits interference signal.

Wherein, to the inhibition of interference signal i.e. by interference reduction.Reduced mode can there are many for example including interference pair Disappear, interference reduction is eliminated, and interference is avoided.

Interference cancellation refers to that messaging parameter (the mainly coding of interference signal in step S506 can be used in target terminal Parameter) signal opposite with interference signal is generated, the signal and total data signal are overlapped, thus by way of offseting Interference signal is eliminated from total data signal.Interference reduction, which is eliminated, refers to that leading in step S506 can be used in target terminal Letter parameter (the mainly coding parameter of interference signal) restores interference signal, then in the total data signal of target terminal itself In, the interference signal is subtracted, to inhibit to interference signal.Interfering the specific implementation avoided is that target terminal makes Data letter is sent with the parameter different from the messaging parameter in step S506 (mainly pilot tone be mapped to the communication resource mode) Number.

It may include that (symbol level interference cancel, SL- are eliminated in symbol level interference that interference, which is eliminated, IC) or (code word level interference cancel, CW-IC) is eliminated in the interference of code word grade.Wherein SL-IC is needed Target decoding terminals interference source signal (bit stream for needing to estimate interference source signal) is wanted, CW-IC needs target terminal solution Cadre enrolled among workers disturbs source signal (modulation system etc. for needing to estimate interference source signal).

It carries out the interference of the useful signal PDSCH of target terminal to eliminate to be currently, and PDSCH by neighboring community For interference, after target terminal obtains the messaging parameter of neighboring community, target terminal is according to these messaging parameters and by dry The pilot signal for disturbing signal obtains the PDSCH signal that the interference source of recovery can be calculated in the channel information interfered.Target is whole End obtains the disturbed useful PDSCH resultant signal received, and target terminal subtracts recovery in disturbed PDSCH resultant signal Interference source PDSCH signal, obtain interference eliminate after useful PDSCH, the useful PDSCH is decoded again obtains later Obtain the data information wherein carried.The wherein MCS in the messaging parameter of interference source, port, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (cell radio network temporary identifier, C-RNTI), frame structure, the corresponding order instruction of PDSCH, PDSCH DMRS information is provided to target terminal and carries out the PDSCH signal that interference source is calculated.

From the above technical scheme, the application, can also be by adjacent on the basis of accurately can determine interference source Cell inhibits interference source, or can be by the messaging parameter to target terminal informing interference signal, so that target is whole End inhibits interference, to reduce interference source influence caused by target terminal.

It should be noted that in above embodiments, the messaging parameter that target terminal use when AF panel be all by Neighboring community is sent to target terminal by serving cell.But target terminal can also be obtained by the detection algorithm of itself Obtain some or all of required messaging parameter.Specifically:

In a kind of implementation, neighboring community may notify target terminal about these messaging parameters by serving cell A part of messaging parameter, these messaging parameters be in addition to MCS, order instruction, occupancy resource block other than information.That is, The resource block of MCS, order instruction and occupancy can be estimated by target terminal oneself by detection algorithm.

When estimating these messaging parameters, target terminal can be used neighboring community and notify target terminal by serving cell Some messaging parameters.For example, neighboring community pass through serving cell notify in the messaging parameter of target terminal comprising C-RNTI and PDCCH CORESET configuration, then PDCCH CORESET configuration can be used to search for the PDCCH of interference signal, so in target terminal PDCCH (PDCCH generally uses C-RNTI to be scrambled) is decoded using C-RNTI afterwards, MCS can be obtained after decoding, order refers to The communications parameter informations such as the resource block show, occupied.Or messaging parameter is sent not by scrambled PDCCH, but by servicing Cell is sent to target terminal using wireless heterogeneous networks (Radio Resource Control, RRC) signaling.

Wherein, it includes following two that target terminal, which obtains the implementation of messaging parameter using C-RNTI decoding PDCCH,.

One is neighboring communities to notify C-RNTI of the target terminal interference source in neighboring community, target by serving cell Terminal goes to decoding neighboring community to issue the PDCCH of the interference source according to the C-RNTI, and interference source can be obtained later by decoding PDCCH Some messaging parameters (such as the information such as resource block of MCS, order instruction, occupancy) of signal.

Another kind is that neighboring community is that target terminal sends a PDCCH, and it is small to service which uses neighboring community The mark such as C-RNTI of the target terminal distribution in area is scrambled, or the mark for using serving cell to distribute for target terminal is such as C-RNTI is scrambled.Target terminal goes to decoding neighboring community to issue the PDCCH of interference source according to the C-RNTI, decodes PDCCH Some messaging parameters (such as the information such as resource block of MCS, order instruction, occupancy) of interference source signal can be obtained later.

It should be noted that all interference sources in the interference source group that target terminal may notify serving cell all carry out Decoding PDCCH obtains some messaging parameters of corresponding interference signal.In addition, being needed clear in which control when decoding PDCCH Resource set (coreset) processed is decoded, which can be determination through consultation.
