Description
Technical field
The present invention relates to wireless communication technology field, relate in particular to a kind of channel disturbance and detect implementation.
Background technology
In wireless communication system, wireless frequency spectrum is divided into authorizes frequency range and unauthorized frequency range.Wherein, authorizing frequency range is to aim at the wireless transmission band that a certain radio communication service is opened up, and other wireless device can not carry out the signal transmission in this frequency range; Described mandate frequency range is normally distributed to a certain operator and is used, and by operator the frequency range that each node adopted in the system is optimized, to reduce the phase mutual interference between the node.Unauthorized frequency range then all can freely be used for all radio communication services that meet certain requirements, but, because the frequency that each node adopts is unfixing, and do not carry out the optimization of network based on this frequency range, therefore, for avoiding producing in unauthorized frequency range the compossibility of interference effect system, then corresponding wireless device need carry out corresponding Interference Detection in unauthorized frequency range, to evade interference.
At present, authorize the frequency range availability of frequency spectrum lower, and use unbalanced situation owing in wireless communication system, exist.For this reason, the industry suggestion allows unauthorized user under the situation of not disturbing authorized user, and the use authority frequency range is to improve the utilance of authorizing frequency range.Like this, just require the wireless device can dynamically perception surrounding environment, and according to the adaptive dynamic adjustment of the variation of environment, thereby both can realize effectively utilizing idle frequency spectrum, can avoid again other system is caused interference.
At present, the base station just needed to adopt certain frequency spectrum perception means before connecting system, and whether detect has this frequency range of other CU.As shown in Figure 1, suppose that BS1 adopts frequency f 1, BS2 adopts frequency f 2, and then BS0 can detect f1 shared by BS1, still, owing to BS2 is not in the BS0 coverage, is used so it can't detect f2, and promptly BS0 thinks the f2 free time.Like this, BS0 may adopt f2 to carry out the transmission of information, and at this moment, the terminal that is positioned at the BS0 and the common area of coverage of BS2 will be born the problem of the co-channel interference that comes from BS0 and BS2.
Therefore, existing frequency spectrum perception means make the base station can only perceive coverage to comprise the base station of oneself, do not comprise the base station of oneself and can not perceive coverage.
In order to address the above problem, then can adopt the method for the auxiliary Interference Detection of terminal.As shown in Figure 2, suppose common overlay area, have terminal SS0, and SS0 is linked into BS2 at BS0 and BS2.Based on the application scenarios of Fig. 2, corresponding Interference Detection processing procedure comprises as shown in Figure 3:
When BS0 initially inserts, BS0 can broadcast the information of oneself, SS0 in the coverage of BS0 detects the broadcast singal from BS0, and the broadcast singal of detected BS0 passed to oneself serving BS BS2, the signal that BS2 reports according to terminal SS0 can be learnt to have interference neighbors BS0, afterwards, BS2 notifies BS0 by backbone network, and this frequency is occupied.Therefore, by in the BS0 overlay area, the terminal SS0 that has existed, BS0 can find that frequency f 2 is occupied.
As can be seen, the realization of the auxiliary Interference Detection scheme of above-mentioned terminal is to have circumscribedly, promptly only has the terminal that is associated with the neighbours BS existence that activates in the common coverage of initiate BS and neighbours BS, just can satisfy the needs of Interference Detection.
Therefore, in the auxiliary Interference Detection scheme of described terminal, if do not have other terminal existence at the common area of coverage of IBS and neighbours BS, then initiate BS still has and may select a frequency identical with neighbours BS.As shown in Figure 4, owing to do not have terminal between BS0 and the BS2, thereby BS0 do not detect BS2, and at this moment, BS0 might select the frequency identical with BS2 to transmit.Afterwards, after the terminal that the common area of coverage of two base stations occurs needing to insert, will be owing to the mutual interference mutually of two BS0 and BS2, cause it can't access network, form coverage hole, reduced the communication performance of wireless network.
