Step S110, micro-base station detects the loading condition of the micro-base station.

In the specific implementation, micro-base station can be detected by counting the quantity of the user equipment currently communicated with and determine its loading condition.

Step S111, the micro-base station broadcasts the Auxiliary Pilot Channel according to detected loading condition, the transmission power of dynamic setting Auxiliary Pilot Channel, the micro-base station（A-CPICH, Assistant common pilot channel );So that the user equipment testing result is reported macro base station by the user equipment for detecting the Auxiliary Pilot Channel, so that the interference that the macro base station is caused to the user equipment to the micro-base station is controlled.

In some feasible embodiments, micro-base station can be according to detected by it loading condition, by the transmission power setting of Auxiliary Pilot Channel is increase or reduces, such as, when the duty factor that micro-base station detects it is larger, it is believed that the user equipment in grand net that the micro-base station is subject to（The user equipment communicated with macro base station）Interference than larger, now, the micro-base station can increase the transmission power of the Auxiliary Pilot Channel of broadcast, and the user equipment that can so detect the Auxiliary Pilot Channel also just increases（Such as, the most user equipment in the non-sho region in micro-base station can be detected）, therefore, macro base station can be controlled to more user equipmenies to the interference that micro-base station is caused.And when the duty factor that micro-base station detects it is smaller, it is believed that the interference of the user equipment in the grand net that the micro-base station is subject to is smaller, now, the micro-base station can reduce the transmission power of the Auxiliary Pilot Channel of broadcast, and the user equipment that can so detect the Auxiliary Pilot Channel is also just reduced（Such as, a small amount of user equipment larger to micro-base station interference only existed in the non-sho region of micro-base station can be detected）, therefore, macro base station can be controlled to a small amount of user equipment to the interference that micro-base station is caused, for example, macro base station only can carry out interference control to the user equipment that more serious interference is caused to micro-base station.Also, another of the transmission power of the Auxiliary Pilot Channel of micro-base station reduction broadcast is advantageous in that, it is possible to decrease the power overhead of Auxiliary Pilot Channel.

In some feasible embodiments, micro-base station can broadcast Auxiliary Pilot Channel by diversified forms, such as：The micro-base station can continuously broadcast the Auxiliary Pilot Channel；Or, the micro-base station periodically broadcasts the Auxiliary Pilot Channel；Or, the micro-base station broadcasts the Auxiliary Pilot Channel according to specified irregular time interval. In some feasible embodiments, Auxiliary Pilot Channel of the invention can be Primary Common Pilot Channel

(P-CPICH, Primary Common Pilot Channel), Secondary Common Pilot Channel (S-CPICH, Secondary Common Pilot Channel), it is any in synchronizing channel (SCH, Synchronization Channel).In implementing, micro-base station and user equipment can consult to use in Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel any period as Auxiliary Pilot Channel in advance, so, when the period arrives, the micro-base station and the user equipment know that any in the Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel is Auxiliary Pilot Channel.

In some feasible embodiments, the Auxiliary Pilot Channel of the present invention is the pilot channel outside Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel, and it is made a distinction by channel logo with Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel.Such as, can be by using different spreading factor or cell scrambling to make a distinction from Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel as the Auxiliary Pilot Channel of pilot channel.Now, when Auxiliary Pilot Channel of the invention is pilot channel, the time slot format and bit sequence of its channel still can with Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel time slot format（It is such as the time slot format shown in figure lb）And bit sequence（It is such as figure l c bit sequence）Identical or difference.

Therefore, in some feasible embodiments of the present invention, Ao Jizhan detects the loading condition of the Ao Jizhan；The micro-base station broadcasts Auxiliary Pilot Channel according to detected loading condition, and the transmission power of the Auxiliary Pilot Channel is dynamically set according to the load of the micro-base station；So that the user equipment testing result is reported macro base station by the user equipment for detecting the Auxiliary Pilot Channel, so that the interference that the macro base station is caused to the user equipment to the micro-base station is controlled, the interference with the user equipment in effective non-sho region of the control in micro-base station to micro-base station.

In some feasible embodiments, user equipment is by detecting signal-to-noise ratio（SIR, Signal to Interference Ratio) judge whether to detect Auxiliary Pilot Channel, such as, when user equipment detection signal-to-noise ratio is more than a certain threshold value, then it is assumed that detect Auxiliary Pilot Channel（Such a mode is any Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel suitable for Auxiliary Pilot Channel.And the Auxiliary Pilot Channel is the pilot channel outside Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel, its situation made a distinction by distinctive channel logo and Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel）.Or, user equipment can by detect channel logo specific to Auxiliary Pilot Channel come Judge whether to detect Auxiliary Pilot Channel, such as, when the spreading factor for the channel that user equipment is detected is spreading factor specific to Auxiliary Pilot Channel, then it is assumed that detect Auxiliary Pilot Channel（It is the pilot channel outside Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel, its situation made a distinction by distinctive channel logo and Primary Common Pilot Channel, Secondary Common Pilot Channel, synchronizing channel that such a mode, which is applied to Auxiliary Pilot Channel,）Separately, in implementing, the detection for carrying out Auxiliary Pilot Channel can be also combined by spreading factor and signal-to-noise ratio, such as, when the spreading factor of the channel measured is spreading factor specific to Auxiliary Pilot Channel, it can also determine whether whether signal-to-noise ratio reaches a certain threshold value, if it is, thinking to detect Auxiliary Pilot Channel.

The testing result of the user equipment is reported macro base station by step S211, the user equipment, so that the interference that the macro base station is caused to the user equipment to the micro-base station is controlled.

In some feasible embodiments, the user equipment can send Dedicated Physical Control Channel to the macro base station（DPCCH, Dedicated Physical Control Channel), pass through the feedback information bit of the Dedicated Physical Control Channel（FBI bits) report the interference that the user equipment is caused to the micro-base station to the macro base station.Such as, as shown in Figure 2 b, when the FBI bits value for the Dedicated Physical Control Channel that user equipment is sent to macro base station is " 0 ", represent that the user equipment is not interfered to micro-base station, and when the FBI bits value for the Dedicated Physical Control Channel that user equipment is sent to macro base station is " 1 ", represent that the user equipment causes interference to micro-base station.Certainly, in the specific implementation, also can be " 1 " to FBI values only when user equipment is interfered to micro-base station.And when not interfering, any instruction can not be done.

From the foregoing, it will be observed that in some feasible embodiments of the present invention, the Auxiliary Pilot Channel of user equipment detection micro-base station broadcast；The testing result of the user equipment is reported macro base station by the user equipment, so that the interference that the macro base station is caused to the user equipment to the micro-base station is controlled, the interference with the user equipment in effective non-sho region of the control in micro-base station to micro-base station.

The energy information of the Auxiliary Pilot Channel detected is divided at least two grades by step S311, the user equipment.Such as, such as Fig. 2 c, the energy information (received signal code power and/or the signal to noise ratio of the Auxiliary Pilot Channel that include the Auxiliary Pilot Channel) of the Auxiliary Pilot Channel detected according to the difference of value can be divided into 8 grades by user equipment, its middle grade " 7 " is the maximum grade of energy, namely annoyance level is maximum, grade " 0 " is minimum for the minimum grade of energy, namely annoyance level.So, user equipment reports interference according to different brackets, it is possible to different control dynamics are provided to macro base station, such as, when annoyance level is big, and larger control dynamics can be used, and less control dynamics can be used in annoyance level hour.

Step S312, the user equipment can send enhancing special uplink channel (Enhanced uplink Dedicated Channel to the macro base station, E-DCH), and by the level report of the energy information of Auxiliary Pilot Channel that the user equipment is detected to the control bit of the enhancing special uplink channel to the macro base station, so that the interference that the macro base station is caused according to the different grade to the user equipment to the micro-base station is controlled.

Such as, such as Fig. 2 d, user equipment can be by the grade signaling bit of the energy information of the Auxiliary Pilot Channel detected（In Fig. 2 d,！, X_{L n}) with strengthening the original control bit of special uplink channel（Χ in Fig. 2 d_κη2, Χ_κη1, and X_tfcl, ₇, X_tfcl, 2 , X_tfcl,！) be multiplexed, and combined coding is carried out after multiplexing, if, grade signaling bit is η bits, then E-DCH coded system can be（30,10+ η), channel mapping is then carried out after coding, is ultimately routed on E-DCH channels.

From the foregoing, it will be observed that in some feasible embodiments of the present invention, the Auxiliary Pilot Channel of user equipment detection micro-base station broadcast；The testing result of the user equipment is reported macro base station by the user equipment, so that the interference that the macro base station is caused to the user equipment to the micro-base station is controlled.Interference with the user equipment in effective non-sho region of the control in micro-base station to micro-base station.
