Description
Technical field
The invention belongs to the mobile communication technology field, relate in particular to many area interference inhibition methods of a kind of honeycomb and end-to-end hybrid network.
Background technology
At present, cordless communication network mainly contains two kinds of structures: the Ad-hoc network of the cellular network of centralized control and distributed control.
Cellular network is meant that (User Equipment, the communication between UE) must be passed through base station (BS, perhaps NB, control eNB) to terminal equipment.
The Ad-hoc network is meant between the UE and can directly communicates, and perhaps carries out relaying through another UE.
In cellular network, even two terminal equipments are adjacent very near, the control that also must communicate through the master controller of base station and so on comprises the distribution of resource of control and the use of transmitting power.The benefit that the system of centralized control like this brings is to be convenient to resource management and Interference Control, but shortcoming is also clearly---the service efficiency of resource is not very high.For example, even two UE close proximity also will use double resource to communicate.Therefore,, obtain higher throughput of system, proposed a kind of pattern (Device-to-Device communication, D2D, i.e. end-to-end communication) of equipment room direct communication among the LTE-Advanced in order to improve the frequency spectrum service efficiency.Like this, following communication network will no longer be the network of single-mode, but centralized network and distributed (end-to-end) network and the hybrid network deposited are as shown in Figure 1.We can observe in Fig. 1, and a UE can send data directly for another UE, also can under the control of base station, communicate by letter with another UE, even can communicate with other UE with the base station simultaneously.Compare with the network of single-mode, this hybrid network will bring the gain of bigger systematic function undoubtedly.
For Interference Detection and the inhibition problem between D2D communication and the cellular network communication in single sub-district, we are respectively at international application no: discuss in the patent application of PCT/FI2010/050263, PCT/IB2009/051772 and PCT/IB2010/000655.In fact, when two UE are in cell edge separately, use the D2D pattern communication more suitable than honeycomb mode communication.As shown in Figure 2, D_TxUE and D_RxUE represent respectively D2D communicate by letter centering transmission UE with receive UE.We can see that they are in the edge of sub-district 1 and sub-district 2 respectively.If at this moment adopt the traditional centralized communication mode to realize the communication of the two, because D_TxUE and D_RxUE are positioned at cell edge separately, so signal quality is all very poor; And signal will be through the relaying of two base stations, and therefore not only communication quality can't guarantee, also will bring very big time-delay.And at this moment because this two close adopts the mode of direct end-to-end communication not only can guarantee communication quality, and can avoid big communication delay.
But, in many like this cell scenario, unavoidably will produce the problem of many area interference.Can find out through Fig. 2, D_TxUE and D_RxUE may receive the interference that comes from 3 sub-districts at least: the CeUE11 in the sub-district 1, the CeUE31 in CeUE22 in the sub-district 2 and the sub-district 3 when communicating by letter.Because the resource of each sub-district is an independent allocation in Cellular Networks; (Transmission Time Interval in a certain Transmission Time Interval; TTI); Because dynamic allocation of resources, TxUE and RxUE can not learn the resource allocation information of CeUE31, so CeUE31 possibly cause interference to D2D communication.In order to improve the frequency spectrum service efficiency, frequency duplex factor as one is generally 1, thereby the interference of therefore how coordinating between many sub-districts realizes that D2D communication is the problem that pay close attention to and consider, also is the subject matter that the present invention will solve.
Generally speaking, thus the interference of coordinating between many sub-districts realizes that the problem that D2D communication will solve has two:
(1) when two UE of D2D communication are in the different sub-districts respectively, how to realize that the coordination of resource avoids coming from the interference of these two sub-districts simultaneously?
(2) when communicating by letter, D2D receives the interference that comes from edge customer in the 3rd sub-district, and how is coordinated resource allocation avoided this interference simultaneously?
And address the above problem, the difficult point of a maximum is exactly: considering from receiving ascending resource information only has the time of 4ms to sending data, thus do the communication resource and the resource allocation of CeUE31 how to coordinate between the D2D avoid interference?
Prior art provides some enlightenments to addressing the above problem, and comprises following three kinds of methods:
Method 1: use the principle of soft-frequency reuse, the frequency that the edge customer of three promptly adjacent sub-districts uses is all inequality, as shown in Figure 3.In Fig. 3; Because the used frequency of edge customer of three neighbor cells differs from one another; And frequency use information provides in advance between neighboring user, therefore as long as D2D communication just can avoid interference the frequency (being the corresponding frequency of point-like) of not using Cell 3 edge customers.It should be noted that these three frequencies shown in the figure are not necessarily mean allocation, can be according to the big or small dynamic change of the D2D traffic.Although soft-frequency reuse can address this problem, frequency duplex factor as one has reduced the service efficiency of frequency resource greater than 1, disagrees with the requirement among the LTE.
Method 2: let base station in these three sub-districts separately through X2 interface exchange resource allocation message each other.But the problem of this solution is that the time-delay of X2 interface very big (order of magnitude of general 20ms) is much larger than the time of the 4ms that leaves D2D communication for.Therefore, if adopt this scheme, need the base station in advance at least the time of 20ms carry out the information interchange of RRM, limited the flexibility of cellular system RRM.
Method 3: when the D2D User Recognition when two UE that communicate are in two different sub-districts respectively; Then do not communicate earlier; But make one of them UE switch to the sub-district at another UE place, and communicate again, be about to stride cell scenario and be converted into common cell scenario.But, also limited it and used scene because this method lacks flexibility.
By above-mentioned three kinds of methods can find out no matter adopt which kind of method, the D2D communication that all can not realize striding the sub-district well between resource coordination and avoided coming from the interference of other sub-districts.
Summary of the invention
The objective of the invention is to; To the mutual interference problem that occurs in 2 end-to-end telex network processes that are in different districts in honeycomb and the end-to-end hybrid network; And the end-to-end user's who comes from other sub-districts who receives in 2 end-to-end telex network processes that are in different districts interference problem, a kind of disturbance restraining method is proposed.
To achieve these goals, technical scheme provided by the invention is that many area interference inhibition methods of a kind of honeycomb and end-to-end hybrid network is characterized in that said method comprises:
Step 1: phone user and end-to-end user obtain the sub-district ID and the power control information of this sub-district to the master controller registration of this sub-district;
Step 2: the master controller of neighbor cell exchanges the end-to-end user's of sub-district information separately each other, with the sub-district under definite end-to-end user;

Step 5: the phone user who produces Communication Jamming reports self information and the end-to-end user's that disturbed ID to master controller;
Step 6: the end-to-end user's that the master controller inspection is disturbed ID, when the end-to-end user who is disturbed does not belong to this sub-district, the master controller exchange message of master controller and neighbor cell;
Step 7: the master controller of neighbor cell sends to the end-to-end user that the quilt of this sub-district disturbs with the information of exchange;
Step 8: detected the ascending resource assignment information that oneself belongs to the phone user of sub-district by the reception user among the end-to-end user who disturbs, obtain the information of channelized frequencies;
Step 9: the end-to-end user who is disturbed uses channelized frequencies and carries out end-to-end communication;
Step 10: the phone user who produces Communication Jamming belong to the sub-district master controller judge the phone user's who produces Communication Jamming communication priority and the end-to-end user's communications priority of being disturbed; If produce the phone user's of Communication Jamming communication priority height; Then execution in step 11; Otherwise, execution in step 12;
Step 11: the transmitting power of being controlled self by the end-to-end user that disturbed produces the interference that the phone user of Communication Jamming causes self with opposing;
Step 12: master controller is forbidden dispatching the phone user who produces Communication Jamming, finishes until end-to-end communication.
Saidly judge it self whether is that the phone user who produces Communication Jamming specifically is; The phone user monitors CCCH information; When the signal power of the CCCH information that listens to when setting threshold value; And when employed frequency is identical with the employed frequency of end-to-end telex network in this phone user's setpoint distance when the phone user sends uplink information, think that then this phone user is the phone user who the end-to-end user of the use same frequency in the setpoint distance is produced Communication Jamming.
Said self information comprises the phone user's who produces Communication Jamming positional information.
Said self information comprises the phone user's who produces Communication Jamming id information.
The master controller exchange message of said master controller and neighbor cell specifically is, master controller will produce the end-to-end user that the phone user's of Communication Jamming the quilt of positional information and neighbor cell disturbs through X2 interface ID sends to the master controller of neighbor cell.

Fig. 4 is that many area interference of honeycomb and end-to-end hybrid network suppress method flow diagram.Based on this flow chart, patent of the present invention provides following two embodiment.
Embodiment 1
Step 101: phone user and end-to-end user obtain the sub-district ID and the power control information of this sub-district to master controller (eNB) registration of this sub-district.
Step 102: the master controller of neighbor cell exchanges the end-to-end user's of sub-district information separately each other, with the sub-district under definite end-to-end user.
Step 103: the CCCH information of each phone user's listening center controller broadcasting, and judge whether self is the phone user who produces Communication Jamming; If then execution in step 104; Otherwise, finish whole process.
The information (comprising time and frequency) of each master controller broadcasting CCCH (CCCH), each phone user can both monitor the information of CCCH (CCCH) like this.If the signal power of the information of the CCCH that the phone user listens to (CCCH) is when setting threshold value; And when employed frequency is identical with the employed frequency of end-to-end telex network in this phone user's setpoint distance when the phone user sends uplink information, think that then this phone user is the phone user who the end-to-end user of the use same frequency in the setpoint distance is produced Communication Jamming.
Here should be noted that; In order to save signaling consumption and phone user's transmitting power; When only detecting signal power on the CCCH (CCCH) and being higher than set point than threshold value, the phone user just reports monitoring result information to the master controller of self affiliated subdistrict.
Step 104: the phone user who produces Communication Jamming translates the end-to-end user's who is disturbed ID from the CCCH information that listens to.
Step 105: the phone user who produces Communication Jamming reports self information and the end-to-end user's that disturbed ID to master controller.
Be equipped with the GPS device if produce the phone user of Communication Jamming, then this phone user can obtain the positional information of oneself.Like this, the self information that the phone user of generation Communication Jamming reports to master controller comprises the end-to-end user's that positional information and quilt are disturbed ID, and is as shown in Figure 5.
Step 106: the end-to-end user's that the master controller inspection is disturbed ID, when the end-to-end user who is disturbed does not belong to this sub-district, the master controller exchange message of master controller and neighbor cell.
The master controller exchange message of master controller and neighbor cell specifically is, master controller will produce the end-to-end user that the phone user's of Communication Jamming the quilt of positional information neighbor cell disturbs through X2 interface ID sends to the master controller of neighbor cell.
Here it is to be noted; Because what the present invention solved is the problem that this cell cellular user disturbs the end-to-end telex network of neighbor cell; If therefore find that this cell cellular user will disturb be the end-to-end user's communications of this sub-district the time, with the process of exchange message between can not the generative center controller.This cell cellular user disturbs the problem of this end-to-end user's communications in sub-district, is solved by existing patented technology.
Step 107: the master controller of neighbor cell sends to the end-to-end user that the quilt of this sub-district disturbs with the information of exchange.
This step is actual to be that the master controller of neighbor cell will be produced the end-to-end user that quilt that the phone user's of Communication Jamming positional information, the ID that produces the end-to-end user that the phone user's of Communication Jamming the quilt of power allocation information and neighbor cell disturbs be broadcast to this sub-district disturbs.
Step 108: detected the ascending resource assignment information that oneself belongs to the phone user of sub-district, the information of the frequency that acquisition can be multiplexing by the reception user among the end-to-end user who disturbs.
Because the information of master controller exchange comprises phone user's ascending resource assignment information (UL_MAP information); And the end-to-end user with cognitive function can translate this information (referring to application number be: 201010147047.2; Name is called: the patent application of the frequency spectrum switching method in the distributed cognition radio network), and then know the user's of cellular cell up the frequency information that will take.Then, will be detected these frequency informations by the end-to-end user that disturbed, find those phone users little to the interference of self, the upstream frequency that these users distribute is exactly the frequency that the end-to-end user that disturbed can be multiplexing.And those opposite ends to the big phone user of the interference of end subscriber communication the upstream frequency that will use, then to avoid the use of.
Step 109: the end-to-end user who is disturbed uses this channelized frequencies and carries out end-to-end communication.
(application number: 201010237273.X, title: the access mechanism of the suggestion method and apparatus that the auxiliary mobile terminal equipment autonomously in a kind of base station inserts), end-to-end user seizes the communication resource through RTS/CTS mechanism according to application for a patent for invention.The end-to-end user who includes transmission information in the RTS/CTS signaling and the end-to-end user's of the information of reception id information, and in the CTS signaling, include the priority indicator number of end-to-end user conversation this time.
After the end-to-end user of the information of transmission successfully receives the 3ms of CTS signaling, the end-to-end user of the transmission information of end-to-end communication centering will send data to the end-to-end user of the information of reception.The data format indication is sent on the DCCH channel, and this sends data on the DTCH channel.Physical Uplink Shared Channel in the LTE system that the DTCH channel has been multiplexing in fact (Physical Uplink Shared Channel, frequency PUSCH).
Translate can be multiplexing upstream frequency after (being operable Physical Resource Block PRB information), the end-to-end user who receives information sends to this information the end-to-end user of transmission information at once on the CCCH channel.As long as in 3ms (this require one be satisfied surely), the end-to-end user who receives information just can accomplish with digital coding, the encryption of transmission and be modulated to can be multiplexing PRB on work.Just do not accomplished the resource negotiation process between the end-to-end user in same sub-district like this.
Step 110: the phone user of generation Communication Jamming belongs to the master controller of sub-district and judges the phone user's who produces Communication Jamming communication priority and the end-to-end user's communications priority of being disturbed; If produce the phone user's of Communication Jamming communication priority height; Then execution in step 111; Otherwise, execution in step 112.
The phone user who produces Communication Jamming is monitoring the signaling on the end-to-end communication CCCH always; This signaling comprises the precedence information of end-to-end communication; When the phone user who produces Communication Jamming listens to this signaling; At once this signaling is sent to master controller at nearest ascending time slot, and judge phone user's the communication priority and the communication priority of end-to-end communication by master controller.When the phone user's who produces Communication Jamming communication priority is high, execution in step 111; When the communication priority of end-to-end communication is high, execution in step 112.
Step 111: the transmitting power of being controlled self by the end-to-end user that disturbed produces the interference that the phone user of Communication Jamming causes self with opposing.
By the positional information of the transmission user among the end-to-end user who disturbs according to the phone user who produces Communication Jamming, calculate self with the phone user who produces Communication Jamming between distance, and according to this apart from the transmitting power of adjusting oneself.
Step 112: master controller is forbidden dispatching the phone user who produces Communication Jamming, finishes until end-to-end communication.
In the foregoing description 1, the phone user who produces Communication Jamming has been equipped with the GPS device.Be not equipped with the GPS device if produce the phone user of Communication Jamming, the present invention can also realize through following step:
Step 201: phone user and end-to-end user obtain the sub-district ID and the power control information of this sub-district to master controller (eNB) registration of this sub-district.
Step 202: the master controller of neighbor cell exchanges the end-to-end user's of sub-district information separately each other, with the sub-district under definite end-to-end user.
Step 203: the CCCH information of each phone user's listening center controller broadcasting, and judge whether self is the phone user who produces Communication Jamming; If then execution in step 204; Otherwise, finish whole process.
Step 204: the phone user who produces Communication Jamming translates the end-to-end user's who is disturbed ID from the CCCH information that listens to.
Step 205: the phone user who produces Communication Jamming reports self information and the end-to-end user's that disturbed ID to master controller.
The phone user who produces Communication Jamming is not equipped with the GPS device, then reports the id information of self and the end-to-end user's that disturbed id information to master controller, and is as shown in Figure 6.
Step 206: the end-to-end user's that the master controller inspection is disturbed ID, when the end-to-end user who is disturbed does not belong to this sub-district, the master controller exchange message of master controller and neighbor cell.
Because master controller knows that each produces the phone user's of Communication Jamming ID, therefore can obtain its transmission power information.The master controller exchange message of master controller and neighbor cell specifically is; Master controller is according to the phone user's who produces Communication Jamming id information; To produce the phone user's of Communication Jamming transmission power information, will produce the master controller of the end-to-end user's that the phone user's of Communication Jamming the quilt of transmission power information and neighbor cell disturbs ID transmission neighbor cell then through X2 interface.
Step 207: the master controller of neighbor cell sends to the end-to-end user that the quilt of this sub-district disturbs with the information of exchange.
This step is actual to be that the end-to-end user's that disturbs of the quilt of the master controller of the neighbor cell phone user's that will produce Communication Jamming transmission power information and neighbor cell ID is broadcast to the end-to-end user that the quilt of this sub-district disturbs.
Step 208: detected the ascending resource assignment information that oneself belongs to the phone user of sub-district, the information of the frequency that acquisition can be multiplexing by the reception user among the end-to-end user who disturbs.
Step 209: the end-to-end user who is disturbed uses this channelized frequencies and carries out end-to-end communication.
Step 210: the phone user who produces Communication Jamming belong to the sub-district master controller judge the phone user's who produces Communication Jamming communication priority and the end-to-end user's communications priority of being disturbed; If produce the phone user's of Communication Jamming communication priority height; Then execution in step 211; Otherwise, execution in step 212.
Step 211: the transmitting power of being controlled self by the end-to-end user that disturbed produces the interference that the phone user of Communication Jamming causes self with opposing.
By the power information of the transmission user among the end-to-end user who disturbs, adjust the transmitted power of oneself according to the phone user who produces Communication Jamming.
Step 212: master controller is forbidden dispatching the phone user who produces Communication Jamming, finishes until end-to-end communication.
In actual application of the present invention, consider that the neighbor cell phone user may not necessarily interfere with end-to-end communication, we suppose that the starting stage of end-to-end communication is not use the neighbor cell power control information.But, the neighbor cell phone user disturbs when producing end-to-end communication; Make bit error probability (the BER)/Block Error Rate (BLER) of this end-to-end communication/when FER (FER) performance can't meet the demands; Use the power control information that comes from neighbor cell with considering, suitably improve original transmitting power.Intrinsic ARQ (Automatic Repetition reQuest, repeat requests automatically) and HARQ (Hybrid ARQ the mixes automatic repeat requests) mechanism of coupling system can guarantee the requirement of the service quality (QoS) of end-to-end communication again.
As a plurality of neighbor cell phone users disturbed same end-to-end communication to the time, balanced phone user's information is obtained average power control factor carries out transmitting power control.
Beneficial effect of the present invention comprises:
A, the CCCH CCCH that distributes to end-to-end user and data control channel DCCH are private resources, so the testing result on these two channels is thought reliably.
Need between B, base station (master controller) through the information of X2 interface exchange about end-to-end user; Although the time-delay of X2 interface probably has about 20ms; But the exchange of this information was carried out before end-to-end telex network begins; Therefore on time delay, do not have strict restriction, can guarantee the requirement of end-to-end telex network 4ms.
C, consider not to be that each end-to-end telex network is bound to disturbed by the user of the 3rd sub-district, therefore do not need end-to-end telex network to increase transmitting power at the very start, can reduce end-to-end user's transmitting power like this, save the energy.
D, when the priority of end-to-end telex network is higher, the communication mechanism that lets the phone user dodge of advising among the present invention can guarantee end-to-end user's communications quality fully.
E, consider that end-to-end user distance base station is far away, and multiplexing be the upstream frequency resource, so the method for advising among the present invention can't influence the communication quality of cellular system.
The above; Be merely the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, any technical staff who is familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
