Description
Technical field
The invention belongs to the mobile communication technology field, relate in particular to many cell interference suppression 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 refers to that the communication between terminal equipment (User Equipment, UE) must pass through the control of base station (BS, or NB, eNB).
The Ad-hoc network refers between UE and can directly communicate, or carries out relaying by another UE.
In cellular network, even two terminal equipments are adjacent very near, the control that also must communicate by the master controller of base station and so on, comprise the distribution of the resource of the control of transmitting power and use.The benefit that the system of centralized control is like this brought is be convenient to resource management and disturb and control, but shortcoming is also clearly---the service efficiency of resource is not very high.For example,, even two UE close proximity also will communicate by double resource.Therefore, in order to improve the frequency spectrum service efficiency, 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 in LTE-Advanced.Like this, following communication network will be no longer the network of single-mode, but centralized network and distributed (end-to-end) network the hybrid network deposited, as shown in Figure 1.In Fig. 1, we can observe, and a UE can send data directly to another UE, also can under the control of base station, with another UE, communicate by letter, and even can with base station and other UE, communicate simultaneously.With the network of single-mode, compare, this hybrid network will bring the gain of larger systematic function undoubtedly.
For Interference Detection and the inhibition problem between D2D communication and cellular network communication in single community, we are respectively at international application no: in the patent application of PCT/FI2010/050263, PCT/IB2009/051772 and PCT/IB2010/000655, discuss.In fact, as two UE, during all 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 mean respectively D2D communicate by letter centering transmission UE with receive UE.We can see, they are respectively in community 1 and the edge of community 2.If at this moment adopt traditional centralized communication mode to realize the two communication, 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, therefore not only communication quality can't guarantee, also will bring very large time delay.And at this moment very near due to these two distance, adopt the mode of direct end-to-end communication not only can guarantee communication quality, and can avoid larger communication delay.
But, in many like this cell scenario, unavoidably will produce the problem of many area interference.Come as seen in Figure 2, D_TxUE when communicating by letter, may be subject at least coming from the interference of 3 communities with D_RxUE: the CeUE11 in community 1, the CeUE31 in the CeUE22 in community 2 and community 3.Because the resource of each community in Cellular Networks is independent allocation, (Transmission Time Interval in a certain Transmission Time Interval, TTI), dynamic assignment due to resource, TxUE and RxUE can not learn the resource allocation information of CeUE31, so CeUE31 may 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 communities realizes that D2D communication is the problem that pay close attention to and consider, is also the subject matter that the present invention will solve.
Generally speaking, thus coordinating the problem that interference between many communities realizes that D2D communication will solve has two:
(1), when two UE of D2D communication are respectively in different communities, how to realize that the coordination of resource avoids coming from the interference of Zhe Liangge community simultaneously?
(2) be subject to coming from the interference of edge customer in the San Ge community when D2D communication, 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 does the communication resource of how coordinating between D2D avoid interference with the resource distribution of CeUE31?
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 edge customer of adjacent San Ge community is used is not identical, as shown in Figure 3.In Fig. 3, the frequency used due to the edge customer of three neighbor cells differs from one another, and between neighboring user, frequency use information provides in advance, therefore as long as D2D communication just can avoid interference the frequency (being frequency corresponding to point-like) of not using Cell 3 edge customers.It should be noted that not necessarily mean allocation of these three frequencies shown in figure, 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 is greater than 1, has reduced the service efficiency of frequency resource, with the requirement in LTE, disagrees.
Method 2: allow Zhong base station, Zhe Sange community exchange resource allocation message each other by X2 interface separately.But the problem of this solution is, the time delay of X2 interface very large (order of magnitude of general 20ms), much larger than the time of the 4ms that leaves D2D communication for.Therefore, if adopt this scheme, need 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 D2D user recognizes two UE communicating respectively in two different communities, first do not communicate, but make one of them UE be switched to the community at another UE place, then communicate, soon across cell scenario, be converted into common cell scenario.But, because this method lacks flexibility, also limited its use scenes.
By above-mentioned three kinds of methods, can find out no matter adopt which kind of method, all can not realize well across the D2D of community communication between resource coordination and avoided coming from the interference of other communities.
Summary of the invention
The object of the invention is to, for the mutual interference problem occurred in the end-to-end telex network process of 2 in different districts in honeycomb and end-to-end hybrid network, and the end-to-end user's who comes from other communities who is subject in 2 end-to-end telex network processes in different districts interference problem, a kind of disturbance restraining method is proposed.

Fig. 4 is many cell interference suppression methods flow chart of honeycomb and end-to-end hybrid network.Based on this flow chart, patent of the present invention provides following two embodiment.
Embodiment 1
Step 101: the master controller (eNB) of phone user and end-to-end user Xiang Zhe community is registered, and obtains community ID and the power control information of this community.
Step 102: the master controller of neighbor cell exchanges the end-to-end user's of community information separately each other, to determine the community under end-to-end user.
Step 103: the Common Control Channel information of each phone user's listening center controller broadcast, and judge whether self is the phone user who produces Communication Jamming; If so, perform step 104; Otherwise, finish whole process.
The information (comprising time and frequency) of each master controller broadcast Common Control Channel (CCCH), each phone user can both monitor the information of Common Control Channel (CCCH) like this.If the signal power of the information of the Common Control Channel that the phone user listens to (CCCH) is greater than while setting threshold value, and, when the frequency that the frequency of using is used with the end-to-end telex network in this phone user's setpoint distance is identical, think that this phone user produces the phone user of Communication Jamming to the end-to-end user of the use same frequency in setpoint distance when the phone user sends uplink information.
Here should be noted that, in order to save signaling consumption and phone user's transmitting power, signal power on Common Control Channel (CCCH) only detected than threshold value during higher than set point, the phone user just reports monitoring result information to the master controller of self affiliated subdistrict.
Step 104: produce the phone user of Communication Jamming from the Common Control Channel information listened to, translate disturbed end-to-end user's ID.
Step 105: the phone user who produces Communication Jamming reports self information and disturbed end-to-end user's ID to master controller.
Be equipped with the GPS device if produce the phone user of Communication Jamming, this phone user can obtain the positional information of oneself.Like this, produce the ID that self information that the phone user of Communication Jamming reports to master controller comprises positional information and disturbed end-to-end user, as shown in Figure 5.
Step 106: master controller checks disturbed end-to-end user's ID, when disturbed end-to-end user does not belong to this community, and the master controller exchange message of master controller and neighbor cell.
Specifically, master controller will produce the phone user of Communication Jamming disturbed end-to-end user's the ID of positional information neighbor cell by X2 interface sends to the master controller of neighbor cell to the master controller exchange message of master controller and neighbor cell.
Here it is to be noted, due to the present invention's solution is the problem that this cell cellular user disturbs the end-to-end telex network of neighbor cell, therefore if while finding that this cell cellular user will disturb end-to-end user's the communication of Shi Zhe community, by the process of exchange message between can not the generative center controller.This cell cellular user disturbs the problem of the end-to-end user's in this community communication, by existing patented technology, is solved.
Step 107: the master controller of neighbor cell sends to the information of exchange the disturbed end-to-end user of this community.
This step is actual is the disturbed end-to-end user that ID that the master controller of neighbor cell will be produced to the disturbed end-to-end user of the phone user's of Communication Jamming positional information, phone user's the power allocation information that produces Communication Jamming and neighbor cell is broadcast to this community.
Step 108: the reception user in disturbed end-to-end user detects the phone user's of community, own place ascending resource assignment information, the information of the frequency that acquisition can be multiplexing.
Due to the packets of information of the master controller exchange ascending resource assignment information (UL_MAP information) containing the phone user, 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 distributed cognition radio network), and then know the user's of cellular cell the up frequency information that will take.Then, disturbed end-to-end user will be detected these frequency informations, finds those phone users little to the interference of self, and the upstream frequency of these user assignments is exactly the frequency that disturbed end-to-end user can be multiplexing.And the upstream frequency that those opposite ends phone user large to the interference of end subscriber communication will use will be avoided using.
Step 109: disturbed end-to-end user uses this channelized frequencies and carries out end-to-end communication.
According to application for a patent for invention, (application number: 201010237273.X, title: the method and apparatus of the mobile terminal equipment autonomously access that a kind of base station the is auxiliary) access mechanism of suggestion, end-to-end user seizes the communication resource by RTS/CTS mechanism.Include end-to-end user with the end-to-end user's of the information of reception of transmission information id information in the RTS/CTS signaling, and include this time priority indicator number of end-to-end user conversation in the CTS signaling.
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 sends on the DCCH channel, and this sends data on the DTCH channel.The frequency of Physical Uplink Shared Channel in LTE system that the DTCH channel has been multiplexing in fact (Physical Uplink Shared Channel, 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 complete by the data encoding of transmission, encryption and be modulated to can be multiplexing PRB on work.Between the end-to-end user in same community, just do not completed the resource negotiation process like this.
Step 110: the phone user's of the master controller judgement generation Communication Jamming of the community, phone user place of generation Communication Jamming communication priority and disturbed end-to-end user's communication priority, if the phone user's of generation Communication Jamming communication priority is high, perform step 111, otherwise, perform step 112.
The phone user who produces Communication Jamming is monitoring the signaling on the end-to-end communication Common Control Channel always, the precedence information that this signaling comprises 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 by master controller judgement phone user's communication priority and the communication priority of end-to-end communication.When the phone user's who produces Communication Jamming communication priority is high, perform step 111; When the communication priority of end-to-end communication is high, perform step 112.
Step 111: the transmitting power that disturbed end-to-end user controls self produces with opposing the interference that the phone user of Communication Jamming causes self.
Transmission user in disturbed end-to-end user is according to the phone user's who produces Communication Jamming positional information, calculate self with the phone user who produces Communication Jamming between distance, and according to this transmitting power apart from adjustment oneself.
Step 112: master controller forbids that scheduling produces the phone user of Communication Jamming, until end-to-end communication finishes.
Embodiment 2
In above-described embodiment 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 by following step:
Step 201: the master controller (eNB) of phone user and end-to-end user Xiang Zhe community is registered, and obtains community ID and the power control information of this community.
Step 202: the master controller of neighbor cell exchanges the end-to-end user's of community information separately each other, to determine the community under end-to-end user.
Step 203: the Common Control Channel information of each phone user's listening center controller broadcast, and judge whether self is the phone user who produces Communication Jamming; If so, perform step 204; Otherwise, finish whole process.
Step 204: produce the phone user of Communication Jamming from the Common Control Channel information listened to, translate disturbed end-to-end user's ID.
Step 205: the phone user who produces Communication Jamming reports self information and disturbed end-to-end user's ID to master controller.
The phone user who produces Communication Jamming is not equipped with the GPS device, to master controller, reports the id information of self and disturbed end-to-end user's id information, as shown in Figure 6.
Step 206: master controller checks disturbed end-to-end user's ID, when disturbed end-to-end user does not belong to this community, and the master controller exchange message of master controller and neighbor cell.
Because master controller is known the phone user's of each generation Communication Jamming ID, so can obtain its transmission power information.The master controller exchange message of master controller and neighbor cell specifically, 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, then by X2 interface, will produce the disturbed end-to-end user's of phone user's the transmission power information of Communication Jamming and neighbor cell the master controller of ID transmission neighbor cell.
Step 207: the master controller of neighbor cell sends to the information of exchange the disturbed end-to-end user of this community.
This step is actual is the disturbed end-to-end user that the disturbed end-to-end user's 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 this community.
Step 208: the reception user in disturbed end-to-end user detects the phone user's of community, own place ascending resource assignment information, the information of the frequency that acquisition can be multiplexing.
Step 209: disturbed end-to-end user uses this channelized frequencies and carries out end-to-end communication.
Step 210: produce Communication Jamming community, phone user place the master controller judgement produce phone user's the communication priority of Communication Jamming and disturbed end-to-end user's communication priority, if the phone user's of generation Communication Jamming communication priority is high, perform step 211, otherwise, perform step 212.
Step 211: the transmitting power that disturbed end-to-end user controls self produces with opposing the interference that the phone user of Communication Jamming causes self.
Transmission user in disturbed end-to-end user, according to the phone user's who produces Communication Jamming power information, adjusts the transmitted power of oneself.
Step 212: master controller forbids that scheduling produces the phone user of Communication Jamming, until end-to-end communication finishes.
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 when the neighbor cell phone user produces and disturbs end-to-end communication, while making the bit error probability (BER) of this end-to-end communication/Block Error Rate (BLER)/frame error rate (FER) performance to meet the demands, use by considering the power control information that comes from neighbor cell, suitably improve original transmitting power.Intrinsic ARQ (the Automatic Repetition reQuest of coupling system again, HARQ) and HARQ (Hybrid ARQ, the mixed automatic retransfer request) mechanism, can guarantee the requirement of the service quality (QoS) of end-to-end communication.
When have a plurality of neighbor cell phone users disturbed same end-to-end communication to the time, balanced phone user's information is obtained to average power control factor and carries out transmitting power control.
Beneficial effect of the present invention comprises:
A, the Common Control Channel 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.
Between B, base station (master controller), need to exchange the information about end-to-end user by X2 interface, although the time delay of X2 interface probably has the 20ms left and right, but the exchange of this information was carried out before end-to-end telex network starts, therefore do not have strict restriction on time delay, 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 be disturbed by the user of San Ge community, therefore do not need end-to-end telex network to increase at the very start transmitting power, can reduce so end-to-end user's transmitting power, save the energy.
D, when the priority of end-to-end telex network is higher, the communication mechanism that allows the phone user dodge of advising in the present invention can guarantee end-to-end user's communication 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 in the present invention can't affect the communication quality of cellular system.
