Embodiment
Mention before, have can exist between the different mobile communication system that the adjacent spectra resource distributes and adjacently disturb frequently, and there are following 4 types in this adjacent the interference frequently:
The upward signal that MS sends is to the interference of BS;
The downstream signal that BS sends is to the interference of MS;
The downstream signal that BS sends is to the interference of BS; And
The upward signal that MS sends is to the interference of MS.
And in the above-mentioned four types interference, the most outstanding to the interference of BS with the downstream signal that BS sends, therefore the downstream signal that sends at BS of the method for specific embodiments of the invention and base station is optimized the interference of BS, is reducing the adjacent utilance that guarantees band resource when disturbing frequently.
The communication processing method of the embodiment of the invention and base station are used for the system of carrier aggregation, to component carrier (Component Carrier, transmitting power CC) is controlled, wherein component carrier is exactly the subcarrier of participating in carrier aggregation.
Be example with the TDD mobile communication system, when the TDD mobile communication system is assigned to 50MHz frequency spectrum resource between the 2570MHz-2620MHz, this moment can with this 50MHz frequency spectrum resource with on average/uneven mode distributes to two or more subcarriers, these subcarriers that are assigned to frequency spectrum resource just become component carrier.
The frequency spectrum resource that is assigned to the 50MHz between the 2570MHz-2620MHz with the TDD mobile communication system is example, suppose and have 5 component carrier CC1, CC2, CC3, CC4 and CC5 in the TDD mobile communication system, when then adopting equalitarian distribution method, each component carrier will be assigned to the frequency spectrum resource of 10MHz.
In the communication processing method and base station of the embodiment of the invention, the frequency spectrum resource that is used for downlink transfer that distributes is assigned at least two component carriers, and the transmitting power of component carrier is controlled.
As shown in Figure 1, the communication processing method of the embodiment of the invention is used for first mobile communication system, and wherein, first mobile communication system uses first frequency spectrum resource and at least two component carriers to carry out downlink transfer, and described communication processing method comprises:
In specific embodiments of the invention, this original transmitted power can be the maximum transmission power of the component carrier of described first base station.
In specific embodiments of the invention, should can arrange as required by default thresholding, whether that is to say needs to use the method for the embodiment of the invention to arrange, depend on the frequency interval between the frequency spectrum resource of the frequency spectrum resource of first mobile communication system and second mobile communication system, bigger as this frequency interval, when surpassing 20MHz, then above-mentioned interference is less relatively, does not just need this moment to use the method for the embodiment of the invention to reduce the transmitting power of component carrier.
Suppose interval [A B] Hz of being of frequency spectrum resource of first mobile communication system, and the frequency spectrum resource of second mobile communication system interval is [C D] Hz.If C is greater than B, then the frequency interval between first frequency spectrum resource and second frequency spectrum resource is (C-B) Hz, and greater than D, then the frequency interval between first frequency spectrum resource and second frequency spectrum resource is (A-D) Hz as if A.
And the frequency interval between the frequency spectrum resource of the frequency spectrum resource of first mobile communication system and second mobile communication system is less (as less than 20MHz, as interval 5MHz, even direct neighbor, certainly above numerical value only is for example, should not cause restriction to the concrete value of the frequency interval between the above-mentioned frequency spectrum resource) time, then can use the method for the embodiment of the invention to reduce the transmitting power of component carrier, adjacently disturb frequently to guarantee when utilizing all available spectrum resources, to reduce.
In the communication processing method of the specific embodiment of the invention, utilize all frequency spectrum resources of distributing to first mobile communication system to transmit, therefore improved the frequency resource utilance of first mobile communication system.And simultaneously, because having carried out reducing to the transmitting power of wherein component carrier, first mobile communication system handles, therefore, also can reduce the interference of the base station receiver of second mobile communication system, therefore also can guarantee the throughput of second mobile communication system.
Understand for convenient, earlier the follow-up adjacent-channel interference power ratio ACIR that will mention is described as follows at this.

1/ACIR＝1/ACLR+1/ACS。
Wherein ACLR ACLR (Adjacent Channel Leakage Ratio) weighs side channel and transmits and drop into degree in the receiver pass-band, is defined as the ratio that records power on transmitting power and the adjacent channel.
Adjacentchannel selectivity ACS (Adjacent Channel Selectivity) weighs when having adjacent channel signal, receiver is defined as filter for receiver at the ratio of the decay on the allocated channel and the decay on adjacent channel in the ability of its allocated channel frequency reception useful signal.
A kind of schematic diagram of ACIR model as shown in Figure 3.Can find that therefrom more near at interval with the employed uplink spectrum resource of second mobile communication system, then ACLR is more little, represents more serious to the uplink interference of second mobile communication system.
Because the frequency spectrum resource difference that is assigned to, different component carriers can produce different interference to second mobile communication system, therefore in specific embodiments of the invention, in described at least two component carriers, the first transmitting power reduction amount of the first component carrier correspondence is greater than the second transmitting power reduction amount of second component carrier wave correspondence, wherein, the frequency spectrum resource that arrives less than described second component allocation of carriers of the frequency spectrum resource that is assigned to of described first component carrier and the frequency interval between described second frequency spectrum resource and the frequency interval between described second frequency spectrum resource.

The implication of above-mentioned transmitting power reduction amount being determined rule is described as follows, above-mentioned transmitting power reduction amount is determined in the rule, only expression exists the first such component carrier and second component carrier wave, and the first transmitting power reduction amount of the first component carrier correspondence is greater than the second transmitting power reduction amount of second component carrier wave correspondence.But above-mentioned transmitting power reduction amount is determined rule and is not represented that the frequency spectrum resource and the frequency interval between described second frequency spectrum resource that are assigned to are more little that then the Dui Ying first transmitting power reduction amount is more big, and this is described as follows for example.
The frequency spectrum resource that is assigned to the 50MHz between the 2570MHz-2620MHz with the TDD mobile communication system is example, suppose and have 5 component carrier CC1, CC2, CC3, CC4 and CC5 in the TDD mobile communication system, each component carrier is assigned to the frequency spectrum resource of 10MHz, and the frequency spectrum resource that is assigned to of component carrier and the frequency interval between described second frequency spectrum resource increase successively.
The transmitting power reduction amount of supposing component carrier CC1 correspondence is A, and then the transmitting power reduction amount of component carrier CC1, CC2, CC3, CC4 and CC5 correspondence can be following various possible situation:
A，A-Δ，A-Δ，A-Δ，A-Δ，A-Δ；
A，A-Δ，A-2Δ，A-3Δ，A-4Δ，A-5Δ；
A，A-Δ，A-Δ，A-2Δ，A-2Δ，A-1.5Δ；
……
Above-mentioned various situations all satisfy above-mentioned transmitting power reduction amount and determine rule.
In the specific embodiment of the invention, transmitting power to component carrier is controlled, wherein, the frequency interval of second frequency spectrum resource that is used for uplink of the frequency spectrum resource that is assigned to of the reduction amount of the transmitting power of component carrier and component carrier and second mobile communication system is relevant.
