In traditional dynamic cell selection technique, subscriber equipment is for each Resource Block (ResourceBlock, RB), the descending signal to noise ratio of each base station on this Resource Block in Active Set (Active Set) is calculated according to down-run survey value, then to each Resource Block, the base station selecting signal to noise ratio maximum is as the base station of carrying out downstream signal transmission on this Resource Block, and the ID of the base station of selection and the descending channel information of this base station are fed back to serving BS, at next signal delivery time, by by the base station selected on this Resource Block for user sends downlink data.In traditional dynamic cell selection technique, service can be provided for it in the top-quality base station of selective channel at any time for each Resource Block user, therefore can improve systematic function greatly, especially the performance of cell boundary users.
In the discussion of LTE-A, a kind of dynamic cell has selected the technology combining reticent (Muting) also to be carried out.Dynamic cell is selected to carry out communication process as follows in conjunction with silent technology:
First, the serving BS measured according to subscriber equipment and the downlink reference signal performance number of the strongest adjacent base station, judge cell boundary users equipment; If the power difference of the downlink reference signal of serving BS and the strongest adjacent base station of signal in pre-determined threshold (such as 3dB), then judges that this subscriber equipment is as cell boundary users equipment.
Secondly, cell boundary users equipment calculates the signal to noise ratio of the secondary strong community (namely in neighbor cell) of instantaneous power on current resource block during no signal transmission (Muting) according to measured value, and measured value is fed back to serving BS.
Finally, select situation according to the channel information of user feedback and community, center base station utilizes combined dispatching algorithm to be user resource allocation block in all communities, until the gross power in a certain community is assigned.

Embodiment
The method of the embodiment of the present invention as shown in Figure 1, comprising:
Step 11, based on dynamic cell selection technique, subscriber equipment is selected first community on Resource Block;
Step 12, when described subscriber equipment is the Cell Edge User equipment of described first community, described subscriber equipment calculates the first throughput on described Resource Block and the second throughput according to measurement result;
Described first throughput and the second throughput are respectively the throughput that described subscriber equipment utilizes described Resource Block to reach under silence mode and normal mode;
Under silence mode, if resource block assignments is given this subscriber equipment by the community that instantaneous received power is the strongest, and this subscriber equipment is when being the Cell Edge User equipment of Serving cell, this Resource Block would not be distributed to user in instantaneous received power time strong community, and the transmitting power of described first community own base station on described Resource Block is the twice of usual transmitting power.
Step 13, described subscriber equipment judges whether described first throughput is greater than the twice of the second throughput, obtains a judged result;
Step 14, when described first throughput of described judged result instruction is more than or equal to the twice of the second throughput, the described first community own base station of described subscriber equipment instruction uses silence mode on described Resource Block, otherwise indicates described first community own base station not use silence mode on described Resource Block.
In the specific embodiment of the invention, the first throughput is C (s), and the second throughput is C (s, n), as follows:
C ( s ) = log 2 ( 1 + P * g ( s ) Σ m ≠ s N P * g ( m ) + N 0 )
C ( s , n ) = log 2 ( 1 + 2 * P * g ( s ) Σ m ≠ n , m ≠ s N P * g ( m ) + N 0 )
Wherein, P representation unit transmitted power, g (s) represents the channel fading of described first community own base station s to subscriber equipment, and N is system cell number, N ofor noise, g (n) represents the base station n belonging to adjacent cell that the signal of described first community the is the strongest channel fading to subscriber equipment.
Can be found by above-mentioned description, if do not use silence mode, if the throughput that the edge customer A of the first community can obtain on Resource Block is A1, due in the second community, this Resource Block can also distribute to other users, therefore in the first community and the second community, if do not use silence mode, the throughput that this Resource Block can bring is 2A1;
Under silence mode, if the throughput that the edge customer A of the first community can obtain on Resource Block is B1, but due in the second community, this resource is silenced, any throughput cannot be brought, therefore in the first community and the second community, the throughput summation that under silence mode, this Resource Block can bring is B1.
Consider, if use silence mode, although bring the lifting of performance can to Cell Edge User equipment, but consider the overall performance of system, in the embodiment of the present invention, only when B1 is greater than 2A1, silence mode is just adopted to transmit, therefore, relative to directly adopting silence mode, the throughput of system can be improved.
Certainly, in order to base station end is dispatched, in the embodiment of the present invention, also comprise:

In a particular embodiment of the present invention, when power difference between the first downlink reference signal that described subscriber equipment receives and the second downlink reference signal is less than the threshold value pre-set, described subscriber equipment is Cell Edge User equipment, described first downlink reference signal is the downlink reference signal that serving BS sends, described second downlink reference signal is in the adjacent base station of serving BS, the base station that the signal that described user receives is the strongest.
The method for scheduling resources among cells of the embodiment of the present invention also comprises:
Step 15, federated resource scheduling is carried out according to the feedback of subscriber equipment in base station;
Can be proportional fair algorithm and other resource scheduling algorithm at Resource Block and power distribution method, as under proportional fair algorithm, the preferred value of all users on all Resource Block in all communities be pressed descending order, distributes with this.
Because federated resource scheduling belongs to the category of prior art, be not described in further detail at this.
Step 16, base station calculates a power average value, as follows:
A/(B+C-D)
Wherein A is the total transmitting power in base station, and B is the Resource Block total number of base station, and C is the number of the Resource Block distributing to the subscriber equipment adopting silence mode, and D is the number of the Resource Block be silenced.
Step 17, for usual subscriber equipment, the transmitting of downstream signal is carried out with the first power in base station, for the subscriber equipment adopting silence mode, the transmitting of downstream signal is carried out with the second power in base station, described first power is described power average value, and described second power is 2 times of described power average value.

And utilize the method for the embodiment of the present invention, first power is divided into (B+C-D)=12 part, 2 parts of power distributing respectively with the Resource Block of the power emission of twice in 12 parts are needed to 4, therefore, also remaining 4 parts of power, can divide equally to 4 remaining Resource Block, therefore, all Resource Block can both use, and can improve the throughput of system.
Assuming that total transmitting power of base station, base station one has 10 Resource Block, then power is divided into 10 parts, suppose there is 2 Resource Block to need with the power emission of twice, 4 Resource Block are silenced, then the current actual Resource Block that can use in base station is 6, if utilize the method for prior art, because need the transmitting power employing 40% with 2 of the power emission of twice Resource Block, and the transmitting power of 40% is used with 4 of the power emission of 1 times Resource Block, then also the transmitting power of remaining 20% does not utilize, and will inevitably reduce the throughput of system.
