Embodiment
Below embodiment is described in detail, but not as a limitation of the invention.
As shown in Figure 3, the described overload indicator of the embodiment of the invention takies interference sections statistical report triggering method on the physical resource to terminal, and concrete implementation step comprises:
It is internal layer area, transitional region and outer zone that step 101, the zone that base station (BS) covers the base station are divided into three layers, and is provided for judging that terminal belongs to the interference threshold of which layer region;
In the present embodiment, be provided with two interference thresholds i.e. first interference threshold and second interference threshold, the zone that the base station is covered is from being divided into three layers in logic, as shown in Figure 1.Also promptly:
As the high reject signal intensity of terminal (also i.e. maximum in the interference signal intensity of all neighbor cells) be lower than (less than or smaller or equal to) first interference threshold, judge that then this terminal is in internal layer area, internal layer area is that the interference signal intensity of terminal minizone is very low even do not have, and can ignore the zone of the influence of presence of intercell interference;
High reject signal intensity as terminal be higher than (greater than) second interference threshold, judge that then this terminal is in the outer layer zone territory, this zone is the highest zone of presence of intercell interference impact probability, the processing of presence of intercell interference must be carried out to this zone, otherwise the throughput and average user terminal (UT) throughput of Cell Edge User terminal (UT) can be influenced;
High reject signal intensity as terminal is lower than second interference threshold and is higher than first interference threshold, judges that then this terminal is in transitional region, and this zone is between internal layer area and outer zone, and high reject signal level is in the acceptable scope;
The transitional region that passing threshold is divided has mainly acted on two:
(1) the be interfered outer zone of strength ratio of signal of this transitional region is little, when user terminal (UT) is in this zone, can reach target transmit power by suitable adjustment road loss compensation factor, reduced because of improving the interference that transmitting power causes other user terminals (UT) and adjacent cell in the cell coverage area, increase the flexibility when path loss compensates simultaneously, effectively raised the throughput and average user terminal (UT) throughput of the Cell Edge User terminal (UT) in the cordless communication network;
(2) this transitional region and internal layer area and outer regional employed running time-frequency resource keep quadrature, be that Physical Resource Block (PRB) keeps quadrature, when internal layer area or outer zone overweight or fully loaded when causing shared running time-frequency resource too much because of load, the running time-frequency resource of this transitional region can be used as effectively and replenishes, and has guaranteed the orthogonality of additional back running time-frequency resource simultaneously;
The availability of frequency spectrum when in a word, introducing transitional region and solve control of part power and path loss compensation effectively descends and load problem such as dispatching flexibility reduction when heavier;
Base station coverage area in the cordless communication network is divided, make the base station on frequency domain, dispatch the employed Physical Resource Block of user terminal (UT) (PRB), it is not used by the user terminal in the adjacent cell (UT), the up-link transmission power of the different layers after control is divided simultaneously carries out the coordination of presence of intercell interference, and do not having under the prerequisite of bandwidth loss, improve Cell Edge User terminal (UT) throughput and average user terminal (UT) throughput in the cordless communication network.
The selection of the activation threshold value of overload indicator report with the triggering times of final decision overload indicator report, thereby has influence on overhead.In the present embodiment, activation threshold value represents that with ratio value concrete implication will be described hereinafter.
The setting of the activation threshold value of different layers is that outer minimum, internal layer are maximum.
In addition, above step 101 and 102 configuration are in no particular order.
After step 104, base station were received reporting of user terminal, if judge the current interference signal intensity of this user terminal greater than (or the more than or equal to) comparison threshold value that the base station is determined, then execution in step 109, otherwise execution in step 105;
The OI grade of PRB is determined can be with reference to existing relevant criterion.
When having a plurality of layering, when triggering overload indicator report, only send the overload indicator report of this layering, so that reduce overhead according to the activation threshold value of the overload indicator report of different layerings.
Below to being elaborated with some examples to the statistics of classification with to the judgement that triggers in step 106 and 107.
As shown in Figure 4, the concrete Application Example of overload indicator (OI) report triggering in LTE.3 of overload indicator ranks are respectively " high (H) ", " in (M) ", " low (L) " among Fig. 4.
Suppose among Fig. 4 when user terminal (UT) takies 12 Physical Resource Block (PRB) that the grade of the overload indicator of different PRB (OI) distributes.
In one example, the base station is only added up for the Resource Unit of " height " overload indicator grade in the user terminal, then has 5 Resource Units to be added up, and the percentage that accounts for the sum of whole Physical Resource Block is (5/12) * 100 (%)=42%; The activation threshold value of supposing the overload indicator report of this user terminal layering of living in is 30% o'clock and since the statistics of base station greater than or more than or equal to the activation threshold value of overload indicator report (42% greater than 30%), then overload indicator report will be triggered.
In addition, the activation threshold value contrast of the overload indicator report of the result of base station statistics and the layering of user terminal place among the present invention, the statistics here can also adopt overload indicator that the more accurate interference signal intensity to user terminal of method of multiple graded combination statistics is analyzed;
For example, in another example, can adopt PRB to add up among the embodiment of Fig. 4 to H and M in the overload indicator report grade, at this moment, there are 5 to be added up for the PRB of H adds up, has the PRB of 3 M, promptly always have 8 PRB, if still adopt the activation threshold value (30%) of the overload indicator report of above-mentioned user terminal place layering, then overload indicator report still is triggered;
Notice that when adopting a plurality of graded combinations to add up, the statistics of different classifications can adopt different activation threshold values.Activation threshold value as the H level is 30%, and the activation threshold value of M level is 70%.As long as the statistical value that one of them grade arranged greater than or more than or equal to activation threshold value, promptly trigger overload indicator report.
Adopt the method for single hierarchical statistics and a plurality of hierarchical statistics can unite use, for example, the statistics numbers of H is more in classification, promptly this statistics numbers is greater than to the statistics numbers preset threshold value of H level the time, can only select single hierarchical statistics, more help reflecting the disturbed condition of user terminal (UT), for, the H number is less in the classification, the M number relatively more for a long time, promptly the statistics numbers of this H level smaller or equal to or less than to the statistics numbers preset threshold value of H level the time, can adopt the method for a plurality of graded combination statistics, so that find the potential disturbed condition of user terminal (UT), help predicting the disturbed condition of user terminal (UT), advanced processing.Add up above 90% as the activation threshold value of H level and M level.
Compared with prior art, adopt the method for the invention by layering to base station coverage area in the cordless communication network, further refinement network, in different layerings by the activation threshold value of overload indicator reasonably is set, in the overload indicator only report greater than or more than or equal to the layering of activation threshold value, further reduced the frequent triggering of overload indicator report effectively, and, improved the validity of overload indicator to the expense that system brings;
In addition, reach by the application in the different base station (BS) of overload indicator in the cordless communication network coverage and to consult load condition between the different base station, coordinate the purpose of presence of intercell interference, simultaneously, in base station range, in the different layering different overload indicator report activation threshold values is set, and can add up by the shared Physical Resource Block (PRB) of user terminal (UT) is upward had the part that has a strong impact on to presence of intercell interference (ICI), and then new overload indicator (OI) triggering mode is set has effectively reduced overload indicator report and trigger the number of times that takes place, thereby reduced the load of overload indicator, and then reduced overhead.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
