FIELD OF THE INVENTION 5 [0001] The present application relates to a communication method and apparatus for a wireless communication network and a wireless communication network. Particularly, the present application relates to a communication method and apparatus for a wireless communication network and a wireless communication network which can adjust an uplink-downlink ratio configuration scheme of a cell cluster in the wireless communication 10 network dynamically. BACKGROUND OF THE INVENTION [0002] In a traditional TDD (Time Division Duplexing) cell communication network, the uplink-downlink ratio configuration scheme cannot be adjusted dynamically. If a cell is to 15 perform service distribution with an intra-frequency or inter-frequency adjacent cell, a bandwidth requirement of service required to be distributed and extra bandwidth resources which can be provided by the cell after the cell's bandwidth requirement for the service of the cell itself is satisfied are compared, after the bandwidth resources (including both uplink bandwidth resources and downlink bandwidth resources) which can be provided by the cell 20 are determined based on the uplink-downlink ratio configuration scheme of the cell, so as to determine how to perform distribution on the service. To be noted, the distribution of data is performed in the unit of a cell. [0003] Recently, under the scenario of heterogeneous networks in a wireless communication network, to enhance the self-adaptivencss of uplink and downlink service 25 transmitting, in version 12 of LTE-A (Long term evolution -Advanced) system, an adjusting mechanism of the uplink-downlink ratio configuration scheme is introduced. SUMMARY OF THE INVENTION [0004] However, when adjusting the uplink-downlink ratio configuration scheme, it is a 30 problem of great challenge whether to take the bandwidth requirement of the distributed -1 - SONY CN Ref: CNPA1205OIN00 Unitalen ref.: OP15I3-06-1057 English Translation of PCT/CN2013/090529 service into consideration. [0005] On one hand, if the bandwidth requirement of the distributed service is not taken into consideration at all, each cell cannot know its distribution situation with neighboring cells, so that the uplink-downlink ratio configuration scheme acquired by adjusting may not well 5 reflect the uplink and downlink bandwidth requirement of the whole network. [0006] On the other hand, if the bandwidth requirement of all the potential distributed service is taken into consideration in an uplink and downlink ratio configuration adjusting period, the quality of service of the service of the cell itself may be affected. Generally, when adjusting the uplink-downlink ratio configuration scheme, the service of the cell itself should 10 have higher priority level than the distributed service. [0007] For this purpose, there is provided a communication method and apparatus for a wireless communication network and a wireless communication system, which can improve the adjustment to the uplink-downlink ratio configuration scheme of the cell cluster, so that the communication efficiency is optimized. 15 [0008] According to an embodiment of the present application, there is provided a communication method for a wireless communication network, wherein: with respect to one cell cluster of at least one cell cluster included in the wireless communication network, based on a predicted non-distributable amount of non-distributable service of each cell in that cell cluster, and a predicted distributable amount of service of each cell in that cell cluster which is 20 able to be distributed with other cells, an uplink-downlink ratio configuration scheme of that cell cluster within a next ratio configuration adjusting period is determined in order to optimize the utilization efficiency of communication resources, and cells in each cell cluster have a same communication frequency and a same uplink-downlink ratio configuration scheme. 25 [0009] According to an embodiment of the present application, there is further provided an apparatus for adjusting an uplink-downlink ratio configuration scheme of cell clusters in a wireless communication network, wherein cells in each cell cluster have a same communication frequency and a same uplink-downlink ratio configuration scheme.

DETAILED DESCRIPTION OF THE INVENTION 5 [0021] Hereinafter, the foregoing and other features and advantages of the present invention will be more apparent by illustrating in detail a preferred embodiment of the present invention in conjunction with accompanying drawings. [0022] In the following, description will be made according to the following order: [0023] 1. The communication method for the wireless communication network 10 [0024] 2. The apparatus for adjusting an uplink-downlink ratio configuration scheme of a cell cluster in a wireless communication network and the wireless communication system [0025] 3. Hardware configuration example 1. The communication method for the wireless communication network [0026] Fig. 1 illustrates a flowchart of a communication method for a wireless 15 communication network according to an embodiment of the present application. In the wireless communication network, at least one cell cluster is included. Cells in each cell cluster have a same communication frequency and a same uplink-downlink ratio configuration scheme. [0027] The wireless communication network is, for example, the wireless communication 20 network 100 shown in Fig. 2. The wireless communication network includes three cell clusters. The first cell cluster includes a cell 111 and a cell 112, and has a first communication frequency. The second cell cluster includes only a cell 120, and has a second communication frequency. The third cell cluster includes only a cell 130, and has a third communication frequency. The frequency point of the first communication frequency is higher than that of the 25 second communication frequency, and the frequency point of the second communication frequency is higher than that of the third communication frequency. To be noted, the wireless communication network 100 can also include another number of cell clusters, for example, only one cell cluster. In addition, the number of cells in each cell cluster can be one or more. [0028] In the following, the communication method for the wireless communication - 5 - SONY CN Ref: CNPA1205OINO0 Unitalenref.:OPI513-06-1057 English Translation of PCT/CN2013/090529 network according to the embodiment of the present application will be described with reference to Fig, 1. [0029] In step S10, processing is started, and proceeds to step SI2. [0030] In step S12, with respect to one cell cluster of the at least one cell cluster included in 5 the wireless communication network 100, a predicted non-distributable amount of non-distributable service of each cell in that cell cluster, and a predicted distributable amount of service of each cell in that cell cluster which is able to be distributed with other cells are acquired, and processing proceeds to step SI4. [0031] As shown in Fig. 1, since coverage ranges of cells may overlap with one another, 10 service of mobile terminals located in the overlapped coverage range may be distributed among different cells. It is to be noted that it is not the case when a mobile terminal of one cell is located in the coverage range of another cell at the same time, the service of the mobile terminal can be distributed between the two cells, factors such as whether the mobile terminal supports the communication mode of the other cell are required to be considered as well. 15 [0032] In addition, although the processing is described only with respect to one cell cluster here, those skilled in the art can understand that the processing can also be performed to all or part of cell clusters included in the wireless communication network 100. [0033] In step S14, with the above mentioned cell cluster, based on the acquired predicted non-distributable amount and predicted distributable amount of each cell in the cell cluster, an 20 uplink-downlink ratio configuration scheme of that cell cluster within a next ratio configuration adjusting period is determined in order to optimize the utilization efficiency of communication resources, and processing proceeds to step S16 and end. [0034] Preferably, when determining the uplink-downlink ratio configuration scheme of that cell cluster for the next ratio configuration adjusting period, it can be further implemented 25 based on a relationship between the predicted distributable amount of each cell in that cell cluster and the service amount which is able to be carried by that cell under each candidate uplink-downlink ratio configuration scheme. Those skilled in the art can understand that other appropriate factors can serve as the basis for determining the uplink-downlink ratio configuration scheme of that cell cluster for the next ratio configuration adjusting period. 30 [0035] When determining based on the predicted non-distributable amount of each cell in - 6 - SONY CN Ref: CNPA12050IN00 Unitalen ref.: OP1513-06-1057 English Translation of PCT/CN2013/090529 that cell cluster and the relationship between the predicted distributable amount of each cell in that cell cluster and the service amount which is able to be carried by that cell under each candidate uplink-downlink ratio configuration scheme, an optional manner is to determine the uplink-downlink ratio configuration scheme, so that a weighted sum of an non-distributable 5 sample amount and a distributable sample amount of each cell in that cell cluster for the next ratio scheme adjusting period is maximum under that uplink-downlink ratio configuration scheme. When the maximum throughput which can be provided by each cell in that cell cluster is larger than or equal to a sum of the predicted non-distributable amount and predicted distributable amount of this cell in the next ratio configuration adjusting period under the 10 uplink-downlink ratio configuration scheme, the non-distributable sample amount and distributable sample amount of this cell in the next ratio configuration adjusting period are equal to the predicted non-distributable amount and predicted distributable amount of this cell respectively. When the maximum throughput which can be provided by each cell in that cell cluster is smaller than a sum of the predicted non-distributable amount and predicted 15 distributable amount of this cell in the next ratio configuration adjusting period under the uplink-downlink ratio configuration scheme, the non-distributable sample amount and distributable sample amount of this cell in the next ratio configuration adjusting period are smaller than or equal to the predicted non-distributable amount and predicted distributable amount of this cell respectively. The specific definition of the non-distributable sample 20 amount and distributable sample amount of this cell in the cell cluster in the next ratio configuration adjusting period will be described later in the Description. [0036] The non-distributable sample amount of each cell in that cell cluster is a portion of the predicted non-distributable amount of that cell which will be carried by that cell under the scheme, and can have a first weight. The distributable sample amount of each cell in that cell 25 cluster is a portion of the predicted distributable amount of that cell which will be carried by that cell under the scheme, and can have a second weight which is smaller than the first weight. The first weight is larger than the second weight, because when considering the allocation of various services among cells, compared with services which can be distributed with other cells, services which can be carried only by the present cell should have higher 30 priority level. [0037] As for the specific values of the first weight and the second weight, those skilled in the art can set properly according to design requirements and actual situation, and the details - 7 - SONY CN Ref: CNPAI2050INOO Unitalenref.: OP1513-06-1057 English Translation of PCT/CN2013/090529 will be omitted here. In addition, in a particular situation, for example, in a situation where the predicted distributable amount has a higher priority level than the predicted non-distributable amount, the first weight can be set to be smaller than the second weight. Therefore, those skilled in the art can properly set the relationship between the first weight and the second 5 weight according to design requirements and actual situation. [0038] In addition, although the non-distributable sample amount and the distributable sample amount are defined as the portion of the predicted non-distributable amount and the predicted distributable amount in the next ratio configuration adjusting period which will be carried by the cell in the cell cluster respective, in fact, the distribution among the cells will be 10 implemented according to the actual situation, rather than necessarily according to the distributable sample amount, in the next ratio configuration adjusting period. This is because the distributable sample amount is only the predication for the service to be occurred in the next ratio configuration adjusting period. As for the non-distributable sample amount, the similar situation also exists. 15 [0039] In particular, the predicted distributable amount of each cell in that cell cluster can include at least one of a predicted intra-frequency distributable amount of sendee of each cell in that cell cluster which is able to be distributed with neighboring cells in that cell cluster and a predicted inter-frequency distributable amount of service of each cell in that cell cluster which is able to distributed with inter-frequency cells outside that cell cluster. In other words, 20 the predicted distributable amount of each cell in that cell cluster can only include the predicted intra-frequency distributable amount of each cell in that cell cluster, can only include the predicted inter-frequency distributable amount of each cell in that cell cluster, or can include the I wo as well. J0040] To be noted, since a distance between cells belonging to different cell clusters under 25 the same communication frequency is generally long and the coverage ranges thereof generally do not overlap with each other, the distribution of service among the cell and identical frequency cells belonging to different cell clusters can not be considered. [0041] The predicted inter-frequency distributable amount of each cell in that cell cluster can include the predicted inter-frequency distributable amount of service distributed from an 30 superordinate cell of that cell. The superordinate cell is a cell of which the communication frequency point is lower than that of that cell and the service coverage overlaps with that cell. - 8 - SONY CN Ref: CNPA12050INOO Unitalenref.:OP1513-06-1057 English Translation of PCT/CN2013/090529 For example, when the cell cluster which the cell 120 belongs to in Fig. 2 is involved, cell 130 is an superordinate cell of the cell 120. Similarly, when the cell cluster which the cells 111 and 112 belong to is involved, cell 120 is an superordinate cell of the cells 111 and 112. In addition, cell 130 is also an superordinate cell of the cells 111 and 112. 5 [0042] During the actual distribution, the direction of distribution of service among each cell in the cell cluster and the superordinate cells of each cell can be bi-directional, i.e., service can be distributed from this cell to its superordinate cell and can be distributed from the superordinate cell to this cell as well. However, on one hand, since it is more common to distribute service from a cell with a lower frequency point of communication frequency and a 10 larger coverage area to a cell with a higher frequency point of communication frequency and a smaller coverage area, on the other hand, to facilitate the description of the distributed service, the distribution of service in the embodiments of the present application is performed from a lower frequency cell to a higher frequency cell. Of course, those skilled in the art can easily derive a technical solution based on an opposite direction of sendee distribution in accordance 15 with the concept of the present application. [0043] Similarly, the predicted inter-frequency distributable amount of each cell in that cell cluster can further include the predicted inter-frequency distributable amount of service of each cell in that cell cluster which is able to be distributed to a lower cell of that cell. The lower cell is a cell of which the communication frequency point is higher than that of that cell 20 and the service coverage overlaps with that cell. For example, when the cell cluster which the cell 120 belongs to in Fig. 2 is involved, cells 111 and 112 are lower cells of the cell 120. Similarly, when the cell cluster which the cell 130 belongs to is involved, cell 120 is the lower cell of the cell 130. [0044] Considering the predicted infra-frequency distributable amount and predicted 25 intcr-frequency distributable amount, an optional manner is to make a weighted sum of the non-distributable sample amount, the distributable intra-frcquency sample amount and the distributable inter-frequency sample amount of each cell in that cell cluster for the next ratio configuration adjusting period be maximum under the determined uplink-downlink ratio configuration scheme. When the maximum throughput which can be provided by each cell in 30 that cell cluster is larger than or equal to a sum of the predicted non-distributable amount, the predicted infra-frequency distributable amount and the predicted inter-frequency distributable amount of this cell in the next ratio configuration adjusting period under the uplink-downlink - 9 - SONY CN Ref: CNPA12050IN00 Unitalen ref.: OP1513-06-1057 English Translation of PCT/CN2013/090529 ratio configuration scheme, the non-distributable sample amount, the distributable intra-frequency sample amount and the distributable inter-frequency sample amount of this cell in the next ratio configuration adjusting period are equal to the predicted non-distributable amount, the predicted intra-frequency distributable amount and the 5 predicted inter-frequency distributable amount of this cell respectively. When the maximum throughput which can be provided by each cell in that cell cluster is smaller than the sum of the predicted non-distributable amount, the predicted intra-frequency distributable amount and the predicted inter-frequency distributable amount of this cell in the next ratio configuration adjusting period under the uplink-downlink ratio configuration scheme, the 10 non-distributable sample amount, the distributable intra-frequency sample amount and the distributable inter-frequency sample amount of this cell in the next ratio configuration adjusting period are smaller than or equal to the predicted non-distributable amount, the predicted intra-frequency distributable amount and the predicted inter-frequency distributable amount of this cell respectively. The specific definition of the distributable intra-frequency 15 sample amount and the distributable inter-frequency sample amount of this cell in the cell cluster in the next ratio configuration adjusting period will be described later in the Description. [0045] The distributable intra-frequency sample amount of each cell in that cell cluster is a portion of the predicted intra-frequency distributable amount of that cell which will be carried 20 by that cell under the scheme, and can have a third weight. The distributable inter-frequency sample amount of each cell in that cell cluster is a portion of the predicted inter-frequency distributable amount of that cell which will be carried by that cell under the scheme, and can have a fourth weight. The first weight can be set to be larger than the third weight, and the third weight can be set to be larger than the fourth weight. The reason for such sellings is thai 25 when considering allocation of various services among cells, services which can only be carried by the present cell have the highest priority level, services which can be distributed with the identical frequency cells belonging to the same cell cluster have the second highest priority level, and services which are distributed from the superordinate cells generally have a lower priority than the previous two. 30 [0046] The specific values of the first weight, the third weight and the fourth weight and the relationship among them can be proper set by those skilled in the art according to design requirements and actual situation as well. - IOSONY CN Ref: CNPA12O5OIN00 Unitalen ref.: OP1513-06-I057 English Translation of PCT/CN2013/090529 [0047] In addition, preferably, taking the situation where the uplink service and downlink service have different priority levels into consideration, an uplink portion and a downlink portion among the non-distributable sample amount, the distributable intra-frequency sample amount and the distributable inter-frequency sample amount of each cell in that cell cluster 5 can be allocated with corresponding weights respectively. In the situation of requiring considering the downlink service more, the weight of the downlink portion can be set higher than the weight of the uplink portion, vice versa. In addition, the weight of the uplink service and the weight of the downlink service can be not preset manually either, but be dynamically determined according to the actual service status of each cell in the eel! cluster. For example, 10 the weight of the uplink service and the weight of the downlink service can be set according to the ratio of the uplink portion to the downlink portion in the predicted distributable amount and predicted non-distributable amount of each cell. When the uplink service occupies a larger proportional in the predicted distributable amount and predicted non-distributable amount of each cell, it can be regarded that the uplink service in this cell cluster is more 15 important, and a higher weight is set for the uplink service portion correspondingly, vice versa. [0048] In addition, when setting the weight, a uniform weight can be set for cells in the whole cell cluster, or weights can be set separately based on the situation of each cell. It is also possible to set different weights for different services according to their importance, so 20 that the important service can be considered first. It is also possible to set weights based on the fact whether the distributed service is from a cell with heavy load, so that the service from a cell with heavy load is distributed first. [0049) When determining the uplink-downlink ratio configuration scheme of the cell cluster in the next ratio configuration adjusting period, selection can be made in a predetermined set 25 of uplink-dovvnimk ratio configuration schemes, For example, in the TD-SCDMA/LTE TDD system, selection can be made among the seven uplink-downlink ratio configuration schemes (that is, scheme 0 to scheme 6) shown in Fig. 3 at a period of 10ms. To those skilled in the art, the uplink-downlink ratio configuration scheme can be selected properly according to other manners, and will not be described in detail here. 30 [0050] After determining the uplink-downlink ratio configuration scheme of that cell cluster for the next ratio configuration adjusting period based on the predicted non-distributable amount, the predicted intra-frequency distributable amount of each cell in the cell cluster and - n - SONY CN Ref: CNPAI205OIN00 Unitalen ref.: OPI513-06-I057 English Translation of PCT/CN2013/090529 the predicted inter-frequency distributable amount of each cell in that cell cluster with other cells, a transmitting power adjusting scheme of each cell in that cell cluster for the next ratio configuration adjusting period is determined. [0051] Specifically, after determining the uplink-downlink ratio configuration scheme of 5 that cell cluster for the next ratio configuration adjusting period, the distributable inter-frequency sample amount to be carried by each cell in the cell cluster in the next ratio configuration adjusting period is also determined. Therefore, it can be determined whether it is necessary to adjust the transmitting power of the cell. If the cell is to carry the distributed service more in the next ratio configuration adjusting period, the transmitting power of the 10 cell can be increased properly, so as to increase the coverage area of the cell and improve the quality of service which the cell provides for the mobile terminals located in the coverage range where the cell and the superordinate cell overlaps. On the contrary, if the cell is to carry the distributed service less or to carry the distributed service in the next ratio configuration adjusting period, the transmitting power of the cell can be decreased properly, so as to save 15 energy. Of course, under proper situations, the transmitting power of the cell can be maintained without any change. [0052] In addition, to be noted, as for the cells in the cell cluster which has the lowest frequency point of communication frequency and the largest coverage range, it is generally not required to adjust the transmitting power thereof. 20 [0053] In addition, after determining the uplink-downlink ratio configuration scheme for one cell cluster in step SI4, processing can not proceed to step SI6, but return to step S12, and processing is continued with respect to the cell clusters to which the superordinate cells of each cell in that cell cluster belongs. [0054] for example, after processing is performed with respect to the cell cluster which the 25 cells 111 and 112 belong to in the wireless communication network 100, processing can be performed with respect to the cell cluster the cell 120 belonging to subsequently, or processing can be performed with respect to the cell cluster the cell 130 belonging to subsequently. [0055] In addition, after processing is performed with respect to the cell cluster which the 30 cell 120 belongs to in the wireless communication network 100, processing can be performed with respect to the cell cluster the cell 130 belonging to subsequently. [0056] To be noted, when processing with respect to subsequent cell clusters, the -12- SONY CN Ref: CNPA120501NOO Unitalen ref.: OP 1513-06-1057 English Translation of PCT/CN2013/090529 uplink-downlink ratio configuration scheme determined with respect to previous cell clusters can be considered to prevent repeated calculation of the predicted inter-frequency distributable amount between cells of different frequencies. In particular, for example, the uplink-downlink ratio configuration scheme of the cell cluster for the next ratio configuration 5 adjusting period can be determined based on the predicted non-distributable amount of each cell in the subsequent cell cluster, the predicted intra-frequency distributable amount of each cell in the subsequent cell cluster, the predicted inter-frequency distributable amount between each cell in the subsequent cell cluster and its superordinate cells, the predicted inter-frequency distributable amount between each cell in the subsequent cell cluster and its 10 lower cells, wherein, the distributable inter-frequency sample amount between each cell in the subsequent cell cluster and the cell in the cell cluster of which the uplink-downlink ratio configuration scheme has been determined is subtracted from the distributable inter-frequency sample amount between each cell in the subsequent cell cluster and its lower cells. [0057] Therefore, if to determine the uplink-downlink ratio configuration schemes with 15 respect to a plurality of cell clusters, processing can be started from a cell cluster with the highest frequency point of communication frequency. In addition, in the wireless communication network, not only the cell clusters whose uplink-downlink ratio configuration scheme can be adjusted (for example, the cells in such a cell cluster operates in TDD manner) but also the cell clusters whose uplink-downlink ratio configuration scheme can not be 20 adjusted (for example, the cells in such a cell cluster operates in FDD (frequency division duplexing) manner) may be included. Generally, the cells in the cell cluster with the lowest frequency point of communication frequency in the wireless communication network operate in FDD manner. As for a cell cluster whose uplink-downlink ratio configuration scheme can not be adjusted, it is possible to consider, when processing with respect to another cell cluster, 25 the predicted inter-frequency distributable amount with the ceils in the cell cluster, but not perform determination of the uplink-downlink ratio configuration scheme with respect to the cell cluster. [0058] To be noted, those skilled in the art can also set other processing orders, for example, an order starting the processing from a cell cluster with the lowest frequency point of the 30 communication frequency, or other proper orders. [0059] In the following, the method for adjusting the uplink-downlink ratio configuration scheme of a cell cluster included in the wireless communication network 100 will be - 1 3 - SONY CN Ref: CNPA12050INOO Unitalenref.: OPI513-06-1057 English Translation of PCT/CN2013/090529 described in detail, taking the wireless communication network 100 in Fig. 2 as an example. [0060] First of all, the uplink-downlink ratio configuration scheme of a cell cluster with the highest frequency point of communication frequency, i.e., the cell cluster to which cells 111 and 112 belong and which has a first communication frequency, is determined. 5 [0061] With respect to the cell 111, its predicted non-distributable amount a ( l l l ) and its predicted distributable amount b(l 11) are acquired. [0062] To be noted, b(n) here denotes the predicted distributable amount flowing into the cell n, wherein n is a number of the cell. [0063] With respect to the cell 112, its predicted non-distributable amount a(112) and its 10 predicted distributable amount b(l 12) are acquired. [0064] Subsequently, with respect to the whole cell cluster, the weighted sum of the non-distributable sample amount Aj(lll) and the distributable sample amount Bj(lll) of the cell 111 as well as the non-distributable sample amount A;(112) and the distributable sample amount Bj(112) of the cell 112 is calculated under the uplink-downlink ratio configuration 15 scheme i. [0065] Assuming the first weight for the non-distributable sample amount is wl, the second weight for the distributable sample amount is w2, the weighted sum of the non-distributable sample amount and distributable sample amount in this cell cluster is x,, the total service amount which can be provided by the cell 111 under the uplink-downlink ratio configuration 20 scheme i is Rj( 111), the total service amount which can be provided by the cell 112 is Rj( 112), the following equation stands: 112 112 Max x ^ w l © ]T Aj(n)+w2@ J] Bf(n) r\=Il! n = l il [0066] A,(n)
