Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.Obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.
Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
For ease of describing, respectively to describe in detail among the embodiment in that the present invention is following, the sub-district that is positioned at same base station range is with the sub-district of standing; Be positioned at same base station range with current area and the sub-district adjacent with current area is with the adjacent area, station; There are two neighbor cells that disturb and belong to same base station with current area, are first with adjacent area, station and second adjacent area, station together; The user who is positioned at the center of housing estate zone is central user; The user who is positioned at cell edge region is edge customer; In the edge customer of current area, be subjected to the first one or more edge customers that disturb with the adjacent area, station and be called first edge customer (or can be described as with first with the adjacent edge customer in adjacent area, station), be subjected to the second one or more edge customers that disturb with the adjacent area, station and be called second edge customer.The embodiment of the invention can carry out controlling with the station adjacent cell interference to the uplink communication process, also can carry out controlling with the station adjacent cell interference to the downlink communication process.
Method embodiment one
Fig. 1 is the control method first embodiment flow chart of the present invention with the station adjacent cell interference, as shown in Figure 1, comprising:
May be to the adjacent area that current area takes place to disturb from the adjacent area and non-of standing together with the adjacent area, station.Non-asynchronous in time with adjacent area, station and current area, can not carry out time domain interference coordination; And stand together adjacent area and current area are synchronous on the time, therefore, can adopt the mode of time domain interference coordination.This step can be determined any two neighbor cells that disturb and belong to same base station with the current area existence according to each adjacent area Reference Signal Received Power of measuring, promptly first stands adjacent area and second together with the adjacent area of standing.Here also can select the stronger neighbor cell of interference ratio to stand adjacent area and second together with the adjacent area, station as first.
In the edge customer of current area, be subjected to the first one or more edge customers that disturb with the adjacent area, station and be called first edge customer, be subjected to the second one or more edge customers that disturb with the adjacent area, station and be called second edge customer.
Edge customer can be according to determining according to this cell reference signals received power (Reference Signal Received Power is called for short RSRP) measured value of current area reporting of user with adjacent area, station RSRP measured value.
The measured value of the RSRP of the adjacent area that edge customer receives is big more, illustrates that the adjacent area is strong more to the interference of edge customer.Thereby can determine the annoyance level of adjacent area by the RSRP of the adjacent area that reports of statistics edge customer to current area.
The first resource occupation rate is illustrated in one section statistics time interval, the Resource Block quantity of the current area that first edge customer takies, with the base station be the ratio of current area Physical Shared Channel (PhysicalShared Channel is called for short PSCH) the frequency resource block total amount of distributing; The second resource occupation rate is illustrated in one section statistics time interval, the Resource Block quantity of the current area that second edge customer takies, with the base station be the ratio of the current area Physical Shared Channel frequency resource block total amount of distributing.
Can reflect first edge customer and the current traffic carrying capacity of second edge customer by the first resource occupation rate and the second resource occupation rate, and the edge of current area load.
When the first resource occupation rate and the second resource occupation rate during all less than first threshold value, first edge customer in the current area and the traffic carrying capacity of second edge customer are less, current area edge load is lighter, open this moment first with the adjacent area, station and second the time domain interference coordination, can not influence the business demand of system with the adjacent area, station.
The resources occupation rate (edge load just) of choosing the edge customer in need consideration a period of time (length of time value will be considered) of the occurrence of first threshold value, concrete can choose according to actual needs.
Time domain interference coordination is exactly within the different time periods, alternately first edge customer and second edge customer is carried out resource allocation.As being the first edge customer dividing frequency resource in odd-numbered frame, and be the second edge customer dividing frequency resource in even frame; Perhaps, in a bit of time second user's dividing frequency resource earlier, be first user's dividing frequency resource then in another short time.
The inventor finds that in realizing the embodiment of the invention process effect of carrying out Inter-Cell Interference Coordination depends on user and professional DYNAMIC DISTRIBUTION situation in the current area, opens interference coordination under different edge load conditions, and performance gain is difference to some extent.For example: when the edge customer traffic carrying capacity was big, the edge of sub-district load was heavy, if it is little to the improvement of systematic function to carry out Inter-Cell Interference Coordination this moment, and can not satisfy the system business demand.Therefore when start the Inter-Cell Interference Coordination operation, when close Inter-Cell Interference Coordination and operate bigger the performance boost of system.
Sub-district under the different base station overlay area is asynchronous in time, can only carry out frequency domain interference and coordinate; And the sub-district under the same base station coverage area (promptly with the sub-district, station) is synchronous in time, therefore, can adopt the mode of time domain interference coordination, the control method of the same station adjacent cell interference that the embodiment of the invention provides focuses on selects suitable opening and closing on opportunity time domain interference coordination function, carry out interference coordination by the method for time domain interference coordination after opening, resource allocation has further improved systematic function.
There are two neighboring BS information of standing together that disturb by obtaining in present embodiment to current area, and calculate respectively and these two resource occupation rates with the adjacent edge customer in adjacent area, station, and then the load condition at judgement current area edge, and with these two the resource occupation rates with the adjacent edge customers in adjacent area, station during all less than first threshold value (load that is the current area edge is less), for current area is opened first with the adjacent area, station and second time domain interference coordination with the adjacent area, station, thereby stagger in time with the interference effect between the adjacent area, station, effectively reduce presence of intercell interference, alleviated the influence of presence of intercell interference to the current area edge customer, improve the throughput of edge customer and the coverage rate of sub-district, and do not influence the throughput of sub-district, thereby improved systematic function as far as possible.
Method embodiment two
Fig. 2 is the control method second embodiment flow chart of the present invention with the station adjacent cell interference.As shown in Figure 2, present embodiment comprises:
Present embodiment obtain with current area exist to disturb belong to the neighbor cell of same base station the time, can there be the most strongly disturbing two neighbor cells that belong to same base station with current area, be referred to as first respectively with adjacent area, station and second adjacent area, station together, judgement exists the most strongly disturbing these two sub-districts when to open time domain interference coordination for current area, in order to reduce presence of intercell interference as much as possible, raise the efficiency.
As for strong jamming adjacent area, for example, the value of the RSRP of each adjacent area of current area reporting of user can be gathered summation, and according to each adjacent area to these RSRP values that report summations, the result of gained is arranged from big to small, select two adjacent areas of first and second as strong jamming adjacent area.
Another embodiment is provided below, obtains current area existence the most strongly disturbing first with adjacent area, station and second adjacent area, station together.Step 2101-step 2109 is for obtaining the embodiment that current area is disturbed the information of the strongest adjacent area, same station.
Current area user reports the base station with the RSRP measured value of the RSRP measured value of the current area of measurement and the adjacent area of standing together.The adjacent area of RSRP measured value maximum is as the strongest adjacent area RSRP measured value in the adjacent area RSRP measured value that the base station receives the user, and the relativeness between judgement current area RSRP measured value and this strongest adjacent area RSRP measured value, thereby determine the wireless position of this user in the sub-district, determine that promptly it still is the current area fringe region that this user is positioned at the current area central area.
If the difference of the current area RSRP measured value of reporting of user and the strongest adjacent area RSRP measured value is less than relative threshold value S
GThe time, can think that then this user is positioned at the fringe region of current area, this user is the edge customer of current area; Otherwise, thinking that then this user is positioned at the central area of current area, this user is the central user of current area.Relative threshold value S
GValue defines definite scope of current area fringe region, can choose according to the strategy of design in advance, for example, relative threshold value S
GBut value is 6dB.
After having obtained the edge customer information of current area, the base station be each edge customer of current area neighboring BS information tabulation of safeguarding a user class (hereinafter referred to as: edge customer neighboring BS information table).Every row stores this edge customer sign (UE-ID), current area sign (serving cell-ID) and RSRP measured value thereof in the edge customer neighboring BS information table, and information such as the adjacent area sign (cell-ID) that reports of this edge customer and corresponding RSRP measured value thereof, and the RSRP measured value descending order of the adjacent area that reports with this edge customer is arranged.Canned data carries out Dynamic Maintenance according to current area user's reporting information in the edge customer neighboring BS information table.
In order to obtain edge customer is disturbed the strongest same station neighboring BS information, the base station can be judged according to the information in the edge customer neighboring BS information table.For example: the base station judge edge customer neighboring BS information table the first capable in the adjacent area (promptly strong jamming adjacent area) of RSRP measured value maximum whether be with the adjacent area, station, for example: the base station can be according to adjacent area, the same station identification information of storing in advance, compare with the adjacent area identification information in the edge customer neighboring BS information table, judge whether this adjacent area is the adjacent area, same station of current area; If the adjacent area identification information in the edge customer neighboring BS information table is identical with adjacent area, the same station identification information of storage in advance, this adjacent area is with the adjacent area, station; Otherwise according to next line RSRP measured value in the edge customer neighboring BS information table, corresponding adjacent area is adjudicated, until obtaining the strongest same station neighboring BS information of the current interference of this edge customer.The base station can disturb each edge customer that obtains the strongest cell-level of same station adjacent cell information maintenance with station neighboring BS information tabulation (hereinafter referred to as: the sub-district is with station neighboring BS information tabulation).The sub-district stores the strongest same station neighboring BS information of the current interference of current area edge customer in tabulating with the station neighboring BS information, and dynamically safeguards; For example: the up-to-date information according to edge customer neighboring BS information table rejudges, to judge that at every turn the strongest same station neighboring BS information and the sub-district of interference that obtains compares with the strongest same station neighboring BS information of the interference of having stored in the neighboring BS information tabulation of station, adopts the strongest same station neighboring BS information of up-to-date interference of obtaining to upgrade the interference the strongest same station neighboring BS information of sub-district with storage in the neighboring BS information tabulation of station.Concrete, if the strongest same station neighboring BS information of up-to-date interference of obtaining be not stored in the sub-district with in the neighboring BS information tabulation of station, then that up-to-date interference of obtaining is the strongest same station neighboring BS information adds this sub-district to in the neighboring BS information tabulation of station; If the strongest same station neighboring BS information of interference of storage does not appear in the strongest same station neighboring BS information of up-to-date interference of obtaining in tabulating with the station neighboring BS information in the sub-district, then in the station neighboring BS information tabulation of sub-district together, delete this and disturb the strongest same station neighboring BS information.
Statistics is (as: time interval T in a period of time
Intra_itvIn), the interference that current area reports at every turn the strongest (RSRP measured value maximum) adjacent area is sub-district each quantity with the edge customer of adjacent area, station with storage in the neighboring BS information tabulation of station, the statistics that these edge customers of current area are reported at every turn adds up, and counts the sub-district with each interference weight w with adjacent area, station correspondence in the neighboring BS information tabulation of station
I, jDisturb weight w
I, jThe following formula that adopts calculate:
Wherein, i is the sequence number of current area; J is that the sub-district is with current area in the neighboring BS information tabulation of the station sequence number of adjacent area, station together; M
iQuantity for edge customer adjacent among the current area i with same station adjacent area j;
Is that sequence number is the number of times of the adjacent area, same station of j for edge customer among the current area i reports interference the strongest with the adjacent area, station; T
Intra_itvBe statistics time interval; L is each timing statistics interval (as: transmission time interval (Transmission Time Interval is called for short TTI)) duration.By formula (1) as can be known, w
I, jValue equals statistics time interval T
Intra_itvIn, the strongest interference in the colocated station adjacent area that all edge customers report in the current area is that sequence number is the total degree of the adjacent area, same station of j.By formula (1), the sub-district all can be calculated with each the strongest interference weights with adjacent area, station correspondence of the interference that comprises in the neighboring BS information tabulation of station.
Each sub-district under the base station covers is with statistics time interval T
Intra_itvBe unit, every T
Intra_itvEach disturbs weights accordingly with the adjacent area of standing in station neighboring BS information tabulation and this tabulation in the sub-district that reports current area to the base station.The information that the base station reports according to each sub-district is upgraded the interior routine weight value with the station neighboring interval of base station range.For example: the interference weights of supposing the sub-district J that cell i reports are 2; The interference weights of the cell i that sub-district j reports are 3, and so, the routine weight value between cell i and the sub-district j is according to separately statistical value, respectively value: from cell i to the routine weight value 2 the j of sub-district, and from sub-district j to the routine weight value the cell i 3.
Below be that value is the special case of minimum value in the routine weight value: suppose that the sub-district that reports with the station cell i is the same station neighboring BS information (w of j with not having sequence number in the neighboring BS information tabulation of station
I, j=0),, the sub-district that the sub-district j that stands together reports includes the same station neighboring BS information (w that sequence number is j in the neighboring BS information tabulation but standing together
J, i〉=1), at this moment, then will be made as minimum value to the routine weight value with station sub-district j with the station cell i, setting in advance as this minimum value is 0.5, then w
I, j=0.5.
Can draw with sub-district, station path profile according to the routine weight value of the minizone, same station that obtains.In with sub-district, station path profile, carry out the path by step 21091-step 21095 and expand, concern thereby obtain with the position with the adjacent area, station in the sub-district, station.
Step 21091, to select any be starting point with sub-district, station, and expands with the direction of routine weight value maximum, and the path termination corresponding district after the expansion is also with the expansion that continues of the direction of its routine weight value maximum.
Step 21093, when closed ring appears in the path expander track, on this closed ring all are denoted as and dispose with sub-districts, station.
Step 21091 and step 21093 have been finished a path expansion.
The method of step 21095, employing step 21091 and step 21093 is carried out other paths expansions, but in the track of other path expansions, can not comprise and be denoted as the sub-district, same station that has disposed, declare when closed ring appears in the path expander track, all sub-districts of standing together on this closed ring are denoted as dispose; Disposed or during only remaining isolated sub-district, finished the path expansion when on the path expander track all are denoted as with sub-districts, station.Fig. 3 a-Fig. 3 d determines the application example of position, adjacent area, station relation together according to the predefined rule of step 21091-step 21095.
Fig. 3 a is the present invention's sub-district, station embodiment path profile together.Shown in Fig. 3 a, each is represented by the solid line of band arrow with the path between the sub-district, station, and mark the routine weight value of this paths correspondence on every paths; Alphabetical A, B, C, D, F and G among Fig. 3 a represents the different districts in the same base station range.
Fig. 3 b is the present invention's station sub-district embodiment path expander schematic diagram first time together.Adopt above-mentioned rule from begin to carry out the path expansion first time with station sub-district A, the path locus after the expansion is: A → F → C → B → G → B; The path locus that forms closed annular in this path locus is B → G → B, will comprise that below 2 closed annular path tracks with the sub-district, station are called the binary ring, and the path locus of closed annular is that B → G → B can be expressed as the binary ring
。To in Fig. 3 b, be denoted as with station sub-district B and G and dispose, like this after can not comprise with sub-district B and the G of standing in the path expander track in other paths.
Fig. 3 c is the present invention's station sub-district embodiment path expander schematic diagram second time together.On the basis of the path expander schematic diagram shown in Fig. 3 b, carry out the path expansion second time, this path expansion is without stand together sub-district B and G; According to above-mentioned predetermined path locus after expanding with rule is A → F → C → D → F; Can obtain closed annular path track according to this path expander track: F → C → D → F; The closed annular path track that below will comprise the sub-district, same station more than 3 or 3 is called polynary ring, like this after can not comprise with station sub-district B, G, F, C and D in the path expander track in other paths.
Fig. 3 d isolates the sub-district schematic diagram for the present invention with station sub-district embodiment.Shown in Fig. 3 d, obviously can't form closed annular path track with the sub-district, station with other with station sub-district A, below can't be called isolated sub-district with the sub-district, same station that the sub-district, station forms closed annular path track with other.
Polynary ring (as: F → C → D → F) is owing to be closed hoop, therefore, if with the starting point F of polynary ring and terminal point F as current area, adjacent with current area F two with station adjacent area C and D be to current area F disturb the strongest two with the adjacent areas, station.For ease of describing, following relative position relations according to two stand together adjacent area C and D and current area F are named, for example: will be from current area F, direction of advance of expanding along the path and the same station adjacent area C adjacent with current area F are called adjacent area, upper end (being first in the embodiment of the invention with the adjacent area, station); And from current area F, opposite direction of expanding along the path and the same station adjacent area D adjacent with current area F are called adjacent area, lower end (being second in the embodiment of the invention with the adjacent area, station).
The consideration of time domain interference coordination is not carried out owing to there are not two adjacent areas, same station that interference is the strongest in sub-district, same station on isolated sub-district, station together and the binary ring therefore; Can carry out RSRP reports processing and neighboring BS relationship to upgrade.
After the first same adjacent area, station and second that obtains current area is with the station neighboring BS information, can be by the mode of inquiry edge customer neighboring BS information table, obtain and be subjected to the described first first edge customer information of disturbing with the adjacent area, station in the current area, and be subjected to the second second edge customer information of disturbing with the adjacent area, station in the current area.
