Need to prove that in addition adjacent relation is mutual, each sub-district in the network all needs to send the uplink-downlink configuration mode that is used to indicate this sub-district, and reception of neighboring cell is used to indicate the uplink-downlink configuration mode of this neighbor cell.From recipient's angle, only need to carry out above-mentioned steps S202-step S204; From sender's angle, only need to carry out above-mentioned steps S201, and step S202-step S204 is finished by the information receiver.
When certain of this sub-district is used for the subframe of up application (or descending application) when corresponding with the subframe that is used for descending application (or up application) of neighbor cell, this subframe that means this sub-district exists potential in the danger of the descending interference of neighbor cell (perhaps the corresponding subframe of this neighbor cell exist potential disturbed by this cell uplink), and this neighbor cell is many more, and is dangerous just big more.So, reportedly fail or Data Receiving in order to reduce even avoid this danger, should try one's best not use this subframe to count, this subframe also promptly is set has lower use priority; Otherwise, if being used for upstream or downstream equally, the subframe that neighbor cell is corresponding with the above-mentioned subframe of this sub-district uses, this subframe that then means this sub-district can be by the descending interference of neighbor cell the uplink interference of neighbor cell (not perhaps to), then should use these subframe transmission data as far as possible or receive data, so can give this subframe higher use priority, so that this subframe is used as far as possible.
Notify neighbor cell to realize the uplink-downlink configuration mode of this sub-district by the announcement information that carries this sub-district uplink-downlink configuration mode by transmission, this announcement information can be only to comprise the information that is used to indicate the uplink-downlink configuration mode, also can be the service cell information (Serving Cell Information) of carrying the field that is used to indicate this sub-district uplink-downlink configuration mode.
Existing service cell information structure is shown in Figure 3, comprises information such as physical layer ID (sign), sub-district ID tracing area number, the PLMN (public land mobile network, public land mobile communication network) of broadcasting and center frequency point.This paper has defined a kind of new service cell information, its structure as shown in Figure 4, compare with existing service cell information, " uplink-downlink configuration mode " field that the service cell information of this paper definition is many, having indicated the current uplink-downlink configuration mode in this sub-district, can be in 7 kinds of uplink-downlink configuration modes shown in the table 1 any one.
Need to prove, according to network practical operation situation or user's request, described " uplink-downlink configuration mode " field also can be to be used for up subframe numbers or to be used for descending subframe numbers, for example " 2,3,7,8 ", the subframe that can represent to be used for up (or descending) is subframe 2, subframe 3, subframe 7 and subframe 8.
Those skilled in the art are elaborated to technical solution of the present invention below by instantiation to the understanding of this programme for convenience.
Certain sub-district obtains the uplink-downlink configuration mode when initially setting up, the X2 interface of transmission is set up request (X2Setup request) message and carried above-mentioned service cell information shown in Figure 4.
This sub-district compares with the uplink-downlink configuration mode of this sub-district after obtaining the uplink-downlink configuration mode of neighbor cell on every side.Particularly, the uplink-downlink configuration situation that compares same sub.Be set for the subframe of up application for certain, by understanding the uplink-downlink configuration situation of same sub in neighbor cell, determine and the neighbor cell quantity that same sub is used for descending application, quantity is many more, the up application of then representing the described subframe of this sub-district is subjected to the possibility of descending interference of neighbor cell big more, then use priority to be provided with lowly more it, quantity is few more, the up application of then representing the described subframe of this sub-district is subjected to the possibility of descending interference of neighbor cell more little, then uses priority to be provided with highly more it.Same, be set for the subframe of descending application for certain, by understanding the uplink-downlink configuration situation of same sub in neighbor cell, determine and the neighbor cell quantity that same sub is used for up application, quantity is many more, the transfer of data of then representing the described subframe of this this sub-district causes the possibility of interference big more to the up application of neighbor cell, then uses priority to be provided with lowly more it; Quantity is few more, represents that then the transfer of data of the described subframe of this this sub-district causes the possibility of interference more little to the up application of neighbor cell, then uses priority to be provided with highly more it.For example in scene shown in Figure 5, there are 6 neighbor cells in sub-district 1, is respectively 2-sub-district, sub-district 7, and the uplink-downlink configuration when sub-district 1 is initially set up is the 2nd kind of Configuration Type, and is as shown in table 2:
Table 2
At each subframe, it uses the set-up mode of priority is similar, is that example describes with subframe 3 and subframe 7 only below:
In sub-district 1, subframe 3 is set for descending application, subframe 7 is set for up application, the use priority of this sub-district subframe 3,7 can be set according to the uplink-downlink configuration situation of the subframe 3,7 of 6 neighbor cells, concrete, can be provided with according to the quantity N1 (or N2) that subframe 3 (or 7) are set for the neighbor cell of up application (or descending application), quantity is many more, uses priority low more.
For example, if described quantity N1=0, the subframe 3 that then means neighbor cell all is set for descending application, the descending application of the subframe 3 of this sub-district can not have influence on the application of the subframe 3 of neighbor cell, at this moment, use priority that can subframe 3 is set to the highest, so that when carrying out descending application, this subframe 3 can be used as far as possible.If described quantity N1=1, mean that then the subframe 3 of 1 neighbor cell is used for up application, the descending application of the subframe 3 of this sub-district may have influence on the up application of the subframe 3 of 1 neighbor cell, but can not influence the application of the subframe 3 of other 5 neighbor cells, it is time high that the priority of subframe 3 that then can this sub-district is set to; ..., and the like, when N1=6, the subframe 3 of 6 neighbor cells of meaning all is used for up application, the descending application of the subframe 3 of this sub-district may have influence on the up application of the subframe 3 of all neighbor cells, and the priority of subframe 3 that then can this sub-district is set to minimum.
In like manner, if N2=0, the subframe 7 that then means neighbor cell all is set for up application, the up application of the subframe 7 of this sub-district can not be subjected to the influence of descending application of the subframe 7 of neighbor cell, at this moment, use priority that can subframe 7 is set to the highest, so that when carrying out up application, this subframe 7 can be used as far as possible.If described quantity N2=1, mean that then the subframe 7 of 1 neighbor cell is used for descending application, the up application of the subframe 7 of this sub-district may be subjected to the influence of descending application of the subframe 7 of 1 neighbor cell, but can not be subjected to the influence of application of the subframe 7 of other 5 neighbor cells, it is time high that the priority of subframe 7 that then can this sub-district is set to, and the like, when N2=6, the subframe 7 of 6 neighbor cells of meaning all is used for descending application, the up application of the subframe 7 of this sub-district may be subjected to the influence of descending application of the subframe 7 of all neighbor cells, and the priority of subframe 7 that then can this sub-district is set to minimum.
After the use priority that each subframe is set according to aforesaid way, sub-district 1 is when selecting subframe to carry out up application or descending application, use priority according to each subframe is selected from high to low, for using the higher subframe of priority, when carrying out the up-downgoing application, can use as far as possible, and for the lower subframe of priority, then optionally use according to the system loading situation, for example when system loading is little, do not use this subframe as far as possible, and when system loading is bigger, suitably use this subframe.
Described according to preamble, when system loading is bigger, use the lower subframe of priority also can be used, this can have influence on communication quality, in some cases, if the user is to the having relatively high expectations of communication quality, then influence communication quality for fear of disturbing big, in the time of can working as quantity N1 or N2 and surpass a default thresholding, determine that this subframe is unavailable.Should can adjust according to network practical operation situation or user's request by default thresholding, its representative value can be the number of cells of the opposite number of cells that is provided with greater than identical setting.The sub-district of described identical setting is: same sub is set for the sub-district of same application (up application or descending application), otherwise the sub-district of described opposite setting is: same sub is set for the sub-district of different application.In other embodiments, when the use priority that also can work as certain subframe is lower than certain default thresholding, determine that this subframe is unavailable.
Above-mentioned example only is described as this sub-district with sub-district 1, for the priority setting of the subframe of other sub-districts, all can carry out according to similar mode, describes in detail no longer one by one at this.
The embodiment of the invention has defined the mode of notifying the uplink-downlink configuration mode between the sub-district mutually, reach the use priority that each sub-frame resources of sub-district is set according to this mode, control the occupation mode of each subframe with this, make that each sub-frame resources can be by rational Application, effectively reduce the interference of minizone, improve power system capacity and efficient.
