Description

A kind of method and apparatus of alien frequencies Interference Detection

Technical field

The present invention relates to communication technical field, especially relate to a kind of method and apparatus of alien frequencies Interference Detection.

Background technology

For TD-LTE (Time Division-Long Time Evolution, time-division Long Term Evolution) system, the cell signal of typical 20MHz bandwidth can be as shown in Figure 1, cell signal strength concentrates in bandwidth of cell, but also there is spurious signal in the both sides outside bandwidth of cell, the intensity of spurious signal reduces gradually, presents feature of roll-offing.Because the suppression of radio-frequency filter to side channel is limited, and the spurious signal transmitted of side channel also will fall in the bandwidth of the radio-frequency filter of this channel, therefore, when the signal of the side channel received is enough large, part PRB (the Physical Resource Block of this channel will be caused, Physical Resource Block) end makes an uproar lifting, and this channel also will be caused time serious to block.Further, for TD-LTE system, between the community of each base station equipment, require clock stringent synchronization.If the frame head between base station equipment or time slot proportion inconsistent, or there is step loss condition in clock, the ascending time slot of downstream signal to another stylobate station equipment that then there will be a stylobate station equipment disturbs, and interference at crossed slot can cause the obvious lifting of the system noise of disturbed base station equipment, and may cause network performance and have a strong impact on, be disturbed serious base station equipment and even normally can not carry out work.As shown in Figure 2, being the schematic diagram that time slot proportion is inconsistent, as shown in Figure 3, is the clock step-out of base station equipment or the inconsistent schematic diagram of frame header deviation.

Such as, the frequency spectrum that China Mobile D frequency range is assigned to is 2575 ~ 2635 common 60M bandwidth, and the frequency spectrum that CHINAUNICOM D frequency range is assigned to is 2555 ~ 2575 common 20M bandwidth, and the frequency spectrum that China Telecom D frequency range is assigned to is 2635 ~ 2655 common 20M bandwidth.When CHINAUNICOM uses 2555 ~ 2575 to set up TD-LTE 20M community, China Mobile uses 2575 ~ 2595 to set up TD-LTE 20M community, if the base station equipment close together of the base station equipment of CHINAUNICOM and China Mobile, and frame head between base station equipment or time slot proportion inconsistent, or step loss condition appears in clock, interference at crossed slot will be there is.When China Telecom uses 2635 ~ 2655 to set up TD-LTE 20M community, China Mobile uses 2615 ~ 2635 to set up TD-LTE 20M community, if the base station equipment close together of the base station equipment of China Telecom and China Mobile, and frame head between base station equipment or time slot proportion inconsistent, or step loss condition appears in clock, interference at crossed slot will be there is.

In prior art; Interference Detection is carried out according to the ascending time slot in the 20MHz bandwidth of this community; to the interfering signal power that each ascending time slot (UpPTS (uplink pilot time slot) and GP (protection interval slots) character position as subframe 2, subframe 3, special subframe 1) receives, all measure according to the granularity of PRB.Wherein, for the interfering signal power of 100 PRB in the 20MHz bandwidth of community, if there is the PRB that interfering signal power exceeds pre-determined threshold, then think that this PRB exists interference.If the interfering signal power of 100 PRB is more smooth, do not possess feature of significantly roll-offing, then think the co-channel interference in this channel.If the interfering signal power of 100 PRB possesses in certain side of bandwidth of cell feature of significantly roll-offing, then think the alien frequencies interference of side channel.Wherein, what alien frequencies disturbed roll-offs feature as shown in Figure 4.

In above-mentioned implementation, by the ascending time slot Interference Detection in this bandwidth of cell, be merely able to learn that interference source frequency is the alien frequencies interference source of co-channel interference source in this channel or side channel, but the concrete frequency point information of alien frequencies interference source cannot be learnt, also the actual interference signal power that this antenna in cell mouth receives cannot be learnt, therefore, above-mentioned implementation is difficult to application in the interference investigation of real network O&M.
