Embodiment
Inventor is realizing noticing in process of the present invention: in identical networking situation, there is the inherent characteristic that co-channel interference is TDD system between multiple cellular cell; The minizone co-channel interference of TD-LTE system can be divided into: closely co-channel interference and remote co-channel interference.Closely co-channel interference is: the interference of uplink/downlink that close two or more communities occur owing to using identical running time-frequency resource, comprising: interfered cell terminal to the uplink interference of base station, disturbed cell, base station, interfered cell to the descending interference of disturbed cell terminal; Because this co-channel interference occurs between the nearer community of standoff distance, therefore this co-channel interference is called closely co-channel interference (near-end interference).Remote co-channel interference is: the interference between base station, specifically refers to the conventional descending sub frame of remote interference base station and the DwPTS interference to disturbed base station UpPTS and regular upstream subframe; Now, due to interference base station and disturbed base station in distance general relatively far apart, therefore the co-channel interference between this base station is called remote co-channel interference (far-end interference).
Owing to not having the localization method for 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 present invention, by the particular geographic location of locating distal interference base station, can when judging to there is far-end interference, the configuration of far-end interference base station and scheduling strategy are adjusted and optimized, thus reduce the sub-frame of uplink of disturbed base station be disturbed degree, to evade the impact of far-end interference, and ensure the receptivity of disturbed base station up channel.
Below in conjunction with the accompanying drawing in the present invention, be clearly and completely described the technical scheme in the present invention, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
From the origin cause of formation of far-end interference, the special subframe configuration of interference base station community and disturbed base station cell will directly have influence on the order of severity of disturbed base station by far-end interference, namely disturbed base station cell is relative to effective GP length of interference base station community, and what affect disturbed base station up channel is disturbed degree.As shown in Figure 3, be the schematic diagram of effective GP length, effective GP length refers to the finish time from the finish time of interference base station community DwPTS to disturbed base station cell GP.As can be seen from Figure 3, when interference base station and disturbed base station distance certain, the length of effective GP is longer, interference base station downstream signal terminate more early, the probability that disturbed base station ascending time slot is interfered is less, or the interference strength be subject to is less.
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, for sending SRS or PRACH Format4(format 4); The length of DwPTS is 3 ~ 11 OFDM symbol, and front 3 symbols are used for transmit control channel PDCCH, PCFICH, PHICH and PSS; Remaining several symbol is for sending PDSCH channel.Because the excursion of DwPTS length is comparatively large, therefore change the special subframe configuration of base station, interfered cell, reduce the symbolic number that DwPTS takies, effectively can extend the length of base station, disturbed cell relative to effective GP of base station, interfered cell; Or when the DwPTS length of interfered cell is greater than 3 OFDM symbol, reduces the dispatching priority of PDSCH channel in DwPTS, also can reduce the influence degree of far-end interference to base station, disturbed cell.
Based on above-mentioned analysis, the embodiment of the present invention one provides the localization method of a kind of far-end interference base station (far-end interference base station namely corresponding to far-end interference cell cluster), the application scenarios of the method can be TD-LTE system, by measuring far end interfering signal, when judging to there is far-end interference, the particular location of far-end interference base station is positioned, thus suitable adjustment is carried out to the scheduling strategy of the configuration of the special subframe of far-end interference base station and DwPTS, with evade far-end interference impact, ensure disturbed base station up channel receptivity; As shown in Figure 4, the localization method of this far-end interference base station comprises the following steps:
