Specific embodiment
Since dual carrier can make full use of existing frequency resource with covering, throughput of system is improved to promote user's sense
Know, therefore it is considered as a kind of following critically important networking mode.Wherein, a carrier wave in dual carrier is used to do covering small
Area, another is used to do capacity and absorbs cell.Current carrier wave turn-off technique mainly for be exactly dual carrier with covering group
Net scene, network is notr busy, in the lower situation of cell business volume, passes through carrier wave turn-off technique and starts green energy conservation mode.
Specifically, base station carries out periodical monitoring to the PRB occupancy of cell, within the preset period (idle), such as
Fruit PRB occupancy is lower than configured threshold, and the user that capacity absorbs under cell is just switched to coverage cell.Base station turns off the load
Wave, i.e. deactivation capacity absorb cell, only protect coverage cell.The transmission power that the antenna of base station can be reduced in this way, to reach
To energy-efficient purpose.Certainly, when PRB occupancy increases and is continued above pre-determined threshold within a preset period of time, then base station is again
It wakes up capacity and absorbs cell.
As it can be seen that existing carrier wave turns off mechanism, base station is only to judge whether base station executes carrier wave pass according to own load
Disconnected, each base station is executing the carrier wave shutdown pattern for not considering adjacent base station when carrier wave shutdown, it is more likely that same
Transmission power is increased on the carrier wave of a reservation, brings the interference between adjacent area.
As user gradually increases bandwidth demand, in current more and more practical application scenes, a base station
The multiple carrier waves of possible configuration, it is to the information exchange of the size of the carrier wave and carrier wave transmission power that specifically have turned off which frequency point outstanding
To be urgent, therefore this case proposes a kind of method for turning off frequency point by interaction carrier wave, and effective section of base station not only may be implemented
Can, and inter-cell interference can be reduced, effective lifting system handling capacity.
The principle of the invention lies in: the carrier information of itself closing is exchanged by the Signalling exchange between base station, in turn
So that base station is when executing carrier wave shutdown, it will be appreciated that the carrier wave of adjacent base station shutdown and the carrier wave of reservation avoid protecting with adjacent base station
Identical carrier wave has been stayed, and then has avoided the interference between adjacent base station.
Embodiment 1:

The intersection of conjunction.
Exemplary, the default carrier set of the base station is { ACDE }, and the traffic carrier collection of the adjacent base station is combined into
{ BCD }, therefore the shutdown carrier set of the base station is { CD }.The default carrier set of adjacent base station is { ABCD }, the base station
Default carrier set be { ACDE }, the carrier wave that the two may use simultaneously has an ACD, and adjacent base station turns off after A there is a possibility that with CD,
The base station is also possible to using CD, therefore the base station can turn off carrier wave CD, uses same load to avoid with adjacent base station
Wave causes the interference of neighboring interval.
106, the base station turns off each carrier wave that the shutdown carrier set includes.
In the specific implementation, base station can not be by needing the carrier wave turned off to carry out data transmission, it can also be according to reservation
Carrier wave adjusts the operating voltage of the power amplifier of base station, has reached energy-saving effect.
Certainly, when the PRB utilization rate in the base station is lower than pre-determined threshold, can turn off the shutdown carrier set includes
Each carrier wave.PRB utilization rate in the base station is higher, and the shutdown carrier set include at least two carrier waves when,
The shutdown part carrier wave for the property of can choose in order to avoid influencing the business of base station, while reducing and using same carrier wave with adjacent base station
Probability.
