Embodiment
The inventor notices in realizing process of the present invention: under the identical networking situation, existing with disturbing frequently between a plurality of cellular cells is the inherent characteristic of TDD system; The minizone of TD-LTE system is with disturbing frequently and can being divided into: closely with disturbing frequently and remote co-channel interference.Closely be with frequently disturbing: close two or more sub-districts since the identical running time-frequency resource of use take place on/descending interference, comprising: the interfered cell terminal is to the descending interference to disturbed cell terminal of the uplink interference of disturbed cell base station, interfered cell base station; Because this interference with frequency occurs between the nearer sub-district of standoff distance, therefore be called closely with disturbing (near-end interference) frequently with interference frequently this.Remote co-channel interference is: the interference between the base station specifically is meant conventional descending sub frame and the DwPTS of the remote interference base station interference to disturbed base station UpPTS and conventional sub-frame of uplink; At this moment, because that interference base station and disturbed base station generally are separated by on distance is far away, therefore the same frequency between this base station is disturbed to be called remote co-channel interference (far-end interference).
Owing to be not directed against the localization method of far-end interference base station in the prior art; Therefore a kind of localization method and equipment of far-end interference base station are provided in the embodiment of the invention; Particular geographic location through location far-end interference base station; Can exist under the situation that far-end disturbs judging, the configuration of far-end interference base station and scheduling strategy are adjusted and optimized, thus reduce disturbed base station sub-frame of uplink receive annoyance level; Evading the influence that far-end disturbs, and guarantee the receptivity of disturbed base station up channel.
To combine the accompanying drawing among the present invention below, the technical scheme among the present invention is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Embodiment one
The origin cause of formation by far-end disturbs can be known; The special subframe configuration of interference base station sub-district and disturbed base station cell will directly have influence on the order of severity that disturbed base station is disturbed by far-end; Just disturbed base station cell affects the annoyance level that receives of disturbed base station up channel with respect to effective GP length of interference base station sub-district.As shown in Figure 3, be the sketch map of effective GP length, effectively GP length is meant the finish time of the finish time of the DwPTS from the interference base station sub-district to disturbed base station cell GP.Can find out that from Fig. 3 under the certain situation of interference base station and disturbed base station distance, effectively the length of GP is long more, the interference base station downstream signal finish more early, the probability that disturbed base station ascending time slot is interfered is more little, the interference strength that perhaps receives is more little.
In the multiple special subframe configuration of TD-LTE system; UpPTS only takies 1 or 2 OFDM (Orthogonal Frequency Division Multiplexing; OFDM) length of symbol is used to send SRS or PRACH Format4 (format 4); The length of DwPTS is 3 ~ 11 OFDM symbols, preceding 3 symbols be used to transmit control channel PDCCH, PCFICH, PHICH and PSS; Remaining several symbol is used to send the PDSCH channel.Because the excursion of DwPTS length is bigger, therefore change the special subframe configuration of interfered cell base station, reduce the symbolic number that DwPTS takies, can prolong the length of disturbed cell base station effectively with respect to effective GP of interfered cell base station; Perhaps, reduce the dispatching priority of PDSCH channel among the DwPTS, also can reduce far-end and disturb influence degree disturbed cell base station when the DwPTS of interfered cell length during greater than 3 OFDM symbols.
