The CoMP operation performed by the structuring method of the CoMP cell cluster not only improves the performance of edge users, but also simultaneously considers the overall performance of the system.
Description
Technical field
The present invention relates to the wireless network communication technique field, particularly a kind of CoMP cell cluster construction method.
Background technology
In recent years, along with the fast development of mobile communication technology, various new business emerge in an endless stream, and meanwhile, the user also improves the performance requirement of GSM thereupon.One of target of the IMT-Advanced system of ITU-R proposition at present is the performance that improves Cell Edge User.Under single cell scenario; Edge customer is because distant apart from the base station; Path loss is more serious, can adopt this moment the method that improves base station transmitting power to satisfy effective Signal to Interference plus Noise Ratio requirement of edge customer in theory, thereby improves the speech quality of edge customer.But in the scene of reality, also deposit a plurality of often sub-districts, and the user of cell edge not only receives the influence of self path loss, the more important thing is, also can receive the serious interference of its neighbor cell.In this case, only improve transmitting power and can not effectively improve user's signal to noise ratio, but should minimize neighbor cell its interference that causes.
Minimize neighbor cell the method that edge customer disturbs is called as disturbance restraining method, existing disturbance restraining method mainly contains: interference randomization, interference eliminated and interference coordination technique.The randomized target of presence of intercell interference is the randomize interference signal; The target of inter-cell interference cancellation is to suppress to disturb at user side; Through the gain on the signal processing technology obtained performance; Inter-Cell Interference Coordination then is through realizing the downlink resource management in a plurality of minizones, realizing the target of intercell interference through the coordinated allocation of resource.Because interference randomization itself can not reduce interference, and inter-cell interference cancellation also can only be eliminated main interference, so these two kinds of methods adopt in prior LTE system is not a lot.The main method that adopts interference coordination mainly comprises fractional frequency reuse (FFR) and soft frequency reuse (SFR) in prior LTE system.In actual scene, the sub-district is owing to receive the influence in building, river etc., and the shape that causes the sub-district is not the hexagonal cell of rule, and in this case, the frequency of FFR and SFR is effectively divided and had great difficulty.And also there is the idle problem of Radio Resource in cell coordination method itself.
To the existing problem of above-mentioned disturbance restraining method, in the IMT-Advanced system, introduced collaborative multicast communication (CoMP) technology.The principle of this technology is that a plurality of base stations adopt the mode of distributed network MIMO to edge customer service to be provided synergistically, thereby improves effective Signal to Interference plus Noise Ratio of edge customer effectively.The prerequisite that adopts this technology is to make up appropriate C oMP cell cluster earlier.
Make up the CoMP cell cluster and be meant that several base stations of selection form one bunch from adjacent a plurality of base stations.Existing C oMP bunch of construction method mainly contains two types, and one type is to form the CoMP cluster method with fixed form, and another kind of is that customer-centric forms CoMP bunch method.The characteristics that form the CoMP cluster method with fixed form are to select the sub-district of fixed number to form bunch, and this method is fairly simple, and the edge customer in bunch adopts bunch size just the same, but the performance boost of this method system is very limited.Customer-centric form CoMP bunch method can form according to user's demand any size bunch, the advantage of this method is that performance gain is bigger, but the problem of the whole network scheduling can occur, causes implementation complexity too high.
In addition, in the existing C oMP construction method, the resource division of non-CoMP and CoMP often adopts fixing mode.Though adopt fixing mode fairly simple, many if the resource ratio is divided irrational words such as the CoMP resource, edge customer is few, and it is limited that this will cause non-CoMP user to insert, and finally causes the decline of power system capacity.The feasible cost that adopts the CoMP profit brought to pay less than system.At last; Existing C oMP mode is not considered the load of neighbor cell; The foundation that just simply is worth CoMP bunch of conduct structure based on user's Signal to Interference plus Noise Ratio (SINR); If the load of neighbor cell itself is very high in this case, CoMP participating mode gesture can cause its decreased performance again, and then has influence on the performance boost of entire system.

Description of drawings
Fig. 1 is the overall flow figure of CoMP cell cluster construction method of the present invention;
Fig. 2 makes up the flow chart of CoMP cell cluster for the mobile subscriber that need do the CoMP operation.
Embodiment
The present invention will be described below in conjunction with accompanying drawing and embodiment.
In a cordless communication network, include a plurality of base stations, there is service range separately each base station, and described service range also is called as the sub-district.In general, there is the intersection region in the minizone of adjacent base station, in the time of near the mobile subscriber is positioned at these intersection regions or intersection region, receives the influence of the wireless signal that sends two above base stations easily.The present invention will be before the CoMP operation be done in the base station, for the user in the cordless communication network makes up the CoMP cell cluster.
As everyone knows, a complete cordless communication network includes many base stations, and with reference to figure 1, the present invention at first selects a wherein adjacent L sub-district, forms the zone that pending CoMP cell cluster makes up.The size of L wherein can be configured based on the demand of reality flexibly.Though will only how to make up the CoMP cell cluster in the present invention explain, it will be understood by those skilled in the art that, can adopt method of the present invention to make up the CoMP cell cluster equally for other base stations in the cordless communication network with regard to a selected L sub-district.
Behind selected L sub-district, for the mobile subscriber in these sub-districts is provided with the SINR threshold value, whether this value capable of using will be done CoMP operation to the mobile subscriber in these sub-districts and tentatively judge in subsequent operation.The SINR value is a value that is used for weighing mobile subscriber's speech quality, and its value is high more, and mobile subscriber's speech quality is just good more.For the mobile subscriber, the setting of SINR threshold value should be according to size, each sub-district geographical environment situation, the interior situation such as traffic carrying capacity size in zone of radius of society.For example; If belong to the city Microcell in institute's favored area; Because radius of society is smaller usually and shadow fading that building causes is more serious; So mobile subscriber's SINR value is generally lower, just can hang down what SINR threshold value relatively established in order to distinguish the poor especially mobile subscriber of those speech qualities this moment.Equally, if the traffic carrying capacity in the zone is bigger, also can relatively hang down what the SINR value was established.When the SINR threshold value was set, the size of this threshold value did not also require in all L sub-district it all is the same, can set different SINR threshold values respectively to the situation of different districts in the zone.Also can also adjust the SINR threshold value based on the different peak hours/period of business, for example at busy traffic period, the SINR threshold value can be provided with low, and in the relatively more idle period of business, it is higher that the SINR value can be established.Adopt the flexible like this method that threshold value is set, can when guaranteeing communication quality, reduce the probability that the CoMP operation takes place, reduce the base station because the recessive expense that the CoMP operation is taken place.In addition,, it will be understood by those skilled in the art that in other embodiments, can adopt also that other is used to weigh the index of mobile subscriber's communication quality in the prior art though adopt the SINR value to weigh mobile subscriber's speech quality in the present embodiment.
Except being provided with for the mobile subscriber in L the sub-district the SINR threshold value, also to calculate all mobile subscribers' in L the sub-district actual SINR value.When calculating the SINR value for the mobile subscriber; The mobile subscriber just can be considered to useful signal from the received signal of its place serving BS; And all be considered to interference signal from the received signal of adjacent base station, therefore, the some users' in the j of sub-district SINR value can be defined as:
Wherein, P
iThe transmitting power of representing i base station, L is the number of base station in the selection area, N
0The expression noise power spectral density, h
iChannel gain between expression mobile subscriber and base station i link.
Need to prove, do not have inevitable front and back order for the mobile subscriber calculates in actual SINR value and the last step between the SINR threshold value for the mobile subscriber is provided with in this step.In other embodiments, both can calculate mobile subscriber's actual SINR value earlier, after the SINR threshold value is set, also can above-mentioned two operations together be carried out.
After the SINR threshold value being set and calculating all mobile subscribers' actual SINR value for the mobile subscriber in L the sub-district; All mobile subscribers' actual SINR value and described SINR threshold value are compared, judge tentatively based on comparative result whether each mobile subscriber will do the CoMP operation.For the mobile subscriber who is not less than given threshold value, then need not carry out the CoMP operation, but, then put into the set R that treats CoMP to this user if the actual SINR value of mobile subscriber is lower than given SINR threshold value.
Mention in the explanation in front, set SINR threshold value can have multiple possible, and therefore, if a plurality of SINR threshold values are arranged in L sub-district, needs according to circumstances compare mobile subscriber's actual SINR value with corresponding SINR threshold value.For example, if each sub-district is set a SINR threshold value separately, then the mobile subscriber's in each sub-district SINR value only needs to compare with this sub-district corresponding threshold.Again for example, if busy traffic period has different SINR threshold values with professional idle period, then each mobile subscriber's the actual SINR value and the SINR threshold value of current time are compared.
Through after the aforesaid preliminary judgement, obtained being used to preserve the user's who treats the CoMP operation set R.Treat each user among the CoMP set R, will be according to the loading condition of its neighbor cell, and each user is made up the CoMP cell cluster respectively according to the definition of similarity.Below with reference to Fig. 2, each user's disposition illustrates among the pair set R.
At first; Judge whether set R is empty; If set R is an empty set; So selected L does not have edge customer in the sub-district, and all sub-districts can be 1 to carry out resource allocation (that is to say and can give non-CoMP operation user with all allocation of radio resources) with the resource multiplex factor all in the zone, also need not to carry out information exchange through X2 interface between the base station.For this type situation, do not make up necessity of CoMP cell cluster, finish associative operation of the present invention.If set R is not an empty set, then can continue to carry out following operation.
Then, select first user among the set R, successively remaining other user among the traversal set R.If other user among the set R has adopted the resource identical with the active user, then these users are called as same subscriber; If other user among the set R has adopted the resource identical with active user's part, then these users are called as similar users; If other user among the set R has adopted the diverse resource with the active user, then these users are called as user inequality.For example, if user a, b, c, d, e, f are arranged, wherein, the resource that user a uses comprises { RB1; RB2}, the resource that user b uses comprises that { resource that user c uses comprises { RB3 for RB1, RB2}; RB4}, the resource that user d uses comprises that { resource that user e uses comprises { RB6} for RB4, RB5}; The resource that user f uses comprise RB7}, user a and b are same subscriber so, user c and d are similar users, user e and f are users inequality.There are aforesaid same subscriber, similar users and user inequality with set A, B, C respectively.During other user in traversal set R, if find same subscriber, the same subscriber that then first user and front is found is taken out from set R and is put in the set A; If do not find same subscriber among the R in set, then travel through R again and seek similar users, if can find similar users, the similar users that then first user and front is found is taken out from set R and is put in the set B; If in set R, both do not found same subscriber not find similar users yet; Just first user is taken out from set R and put into set C; Continue then to select the next user among the set R, repeat aforesaid operations, all users' distribution in accomplishing pair set R.
At last, after will gathering R and being divided into three set A, B, C, will pair set A, the user among the B, C handles according to the height of priority successively.At first; For the user in the set A, owing to adopted identical resource, so this part user's operation is relatively simple; Can operate thereby can carry out CoMP uniformly adopting the same subscriber of same communication resource to be divided into same CoMP cell cluster in the set A.Secondly; For the user in the set B, the resource part that the user adopts is identical, in such cases; A user in the earlier selected set B; It adopts the loading condition of other user's respective cell of part same asset to check the B neutralization then, if the load of respective cell is all lower, then this user is constituted a small set with the user who uses similar resource; Each small set is made up the CoMP cell cluster separately, user's CoMP operation in realizing the CoMP cell cluster through the distribution of the resource coordination between the base station next dispatching cycle; If the load of respective cell is all very high, then the temporary transient earlier not structure of CoMP participating cell cluster in these sub-districts does not carry out the CoMP operation; If the load of part sub-district is not very high, then can constitute the CoMP set of cells with the lower sub-district of these loads, the high sub-district of load need not be participated in.At last, the user among the pair set C handles.When handling; Take out a user among the set C, investigate this user then and belong to the base station of sub-district and the loading condition of neighbor cell base station, if load is lower; Then can make up corresponding C oMP cell cluster; Otherwise investigate other cell base station,, then do not make up the CoMP cell cluster on every side if the load of all cell base stations is all higher.
The present invention has fully combined the loading condition of SINR value and neighbor cell from the angle of system applies, makes that the operation of CoMP is more effective.This method had both improved the performance of edge customer, had also taken into account the performance of entire system simultaneously.In addition, also defined user's similarity among the present invention, and distributed to the different priority of user of different similarity degrees, the system that makes preferentially satisfies the user who satisfies the most easily, the professional providing capability of big as far as possible raising system.
It should be noted last that above embodiment is only unrestricted in order to technical scheme of the present invention to be described.Although the present invention is specified with reference to embodiment; Those of ordinary skill in the art is to be understood that; Technical scheme of the present invention is made amendment or is equal to replacement, do not break away from the spirit and the scope of technical scheme of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
