In traditional physical area, base station sends common channel information and business datum in the gamut of the physical area, and the signal in same physical area shares identical scrambler.As shown in fig.2, each antenna in Cell l all sends SCI (scrambling code informations to the user equipment for accessing the physical area）With business datum 1.
In STSR technologies, each self-corresponding antenna transmitting identical common channel information in two sectors in same virtual subdistrict, base station carries out independent scheduling of resource respectively for each sector.Terminal for establishing wireless connection with base station, base station can determine whether the sector where the terminal, only pass through the sector transmission traffic channel information and user data where the terminal.As shown in fig.2, the corresponding antenna in sector in Cell l' where UE 1, SC1 and business datum 1 are sent to UE 1, the corresponding antenna in sector where UE2 sends SC1 and business datum 2 to UE 2.
Base station is directed to a set of interface-free resources pond of each sector maintenance respectively.If base station carries out independent scheduling to the interface-free resources of each sector, so, different sectors can just reuse identical interface-free resources.In WCDMA（Wideband Code Division Multiple Access, WCDMA) in system, interface-free resources refer to code channel resource and power resource, in Long Term Evolution（ Long Term Evolution ,
LTE) in system, interface-free resources refer to resource block（Resource Block, RB ).But, in UE virtual subdistricts in the case of two adjacent sector crossover regions, once the two adjacent sectors use identical interface-free resources, serious interference just occurs, therefore, adjacent sector can not dispatch identical interface-free resources, and the reusability of interface-free resources is relatively low, limits the lifting of power system capacity.

In macro and micro networks, broad beam can refer to the wave beam that macro station is sent, and narrow beam can be the wave beam that micro- station is sent.In such a scenario, micro- station carrying UE data traffic channels and Auxiliary Pilot Channel, wherein,
Auxiliary Pilot Channel is used for channel estimation and measurement, and macro station then carries the common signal channel of cell level, so as to reduce channel switching.
In the embodiment of the present invention, base station can carry common channel information by broad beam, by narrow beam bearer service data message, realize different channels carrying wave beam separation, can not influence UE mobility etc.
In the case of KPI, the flexibility of Traffic Channel carrying is improved to greatest extent, reduces channel switching.
It is preferred that above-mentioned steps 302 can be realized by any one in following manner：
Mode one：In section at the same time, at least one mutual non-conterminous narrow beam is called in above-mentioned at least two narrow beam；UE based on from the narrow beam called to the narrow beam coverage called sends service data information.
It in mode one, can be, but not limited to realize by following processes, in section at the same time, above-mentioned at least two narrow beam be divided into multiple packets, wherein, some narrow beams included in any one packet are mutually non-conterminous；
Determine each packet calls order；
In above-mentioned section at the same time, order is called to call a packet according to determination.
Call the first narrow beam residing for the UE of current business highest priority；
Service data information is sent by the UE of above-mentioned first narrow beam that calls into above-mentioned first narrow beam coverage in the very first time；The narrow beam adjacent with above-mentioned first narrow beam does not send service data information.
Mode two：The first narrow beam residing for the UE of current business highest priority is called in the very first time；Service data information is sent by the UE of above-mentioned first narrow beam that calls into above-mentioned first narrow beam coverage；The narrow beam adjacent with above-mentioned first narrow beam does not send service data information in the very first time.
So, the priority treatment of the high business of priority can either be ensured, the signal between adjacent beams can be avoided to disturb again.
Mode three：When UE is located in the coverage of single narrow beam, above-mentioned single narrow beam is called to send service data information to above-mentioned UE in the second time, the narrow beam adjacent with above-mentioned single narrow beam does not send service data information in the second time；Or,
When UE is located at the overlapping coverage area of two neighboring narrow beam, it regard the two neighboring narrow beam as an overall narrow beam, in the second time by calling above-mentioned overall narrow beam to above-mentioned UE transmission service data informations, the narrow beam adjacent with above-mentioned overall narrow beam does not send service data information in above-mentioned second time.When using two adjacent narrow beams as an overall narrow beam, the two narrow beams will launch same signal, send identical information.
The above-mentioned very first time（Or second time）Some period or some time point can be represented, for example, certain time period after determining UE positions or at the beginning of a certain cycle between.
Illustrate the preferred embodiments of the present invention one with reference to Fig. 4.
Assuming that in Fig. 4 A, cell A base station has " radio-frequency channel of eight narrow beam-four ", and l-la, l-2a, l-3a, l-4a, l-lb, l-2b, 1-3b and l-4b are respectively 8 narrow beams launched respectively by 8 narrow beam antennas.It is the broad beam 1 launched by broad beam antenna by the dotted line that all narrow beams are included in Fig. 4 A.
Cell A base station sends common channel information by broad beam 1 to UE.Polling cycle is divided into two transmit cycles by cell A base station, and 4 narrow beams are dispatched in the first transmit cycle（L-la, l-2a, l-3a and l-4a), business transmission is carried out by the UE in each narrow beam and the narrow beam coverage respectively；4 narrow beams are dispatched in the second transmit cycle（L-lb, l-2b, l-3b and l-4b), business transmission is carried out by the UE in each narrow beam and the narrow beam coverage respectively.
So, cell A base station carries common channel information by broad beam, pass through narrow beam bearer service data message, realize different channels carrying wave beam separation, and two adjacent narrow beams are called by way of the time-division, make 4 radio-frequency channels polled transmission narrow beam in a certain order, not only it ensure that in a complete polling cycle, each narrow beam has the launch time of identical duration, the interference of adjacent narrow beam is it also avoid, the interface-free resources reusability between adjacent narrow beam is improved.The scheduling mode of wave beam is similar with said process in other cells with 4 narrow beams or more narrow beams.

Assuming that base station determines that dispatching priority highest UE is UE A, also, UE A are in narrow beam 1-3.Because base station determines dispatching priority highest UE in narrow beam 1-3, so, narrow beam 1-3,1-1,1-5 and the 1-7 of base station in the first transmit cycle dispatches the first packet, narrow beam 1-2,1-4,1-6 and 1-8 in the second transmit cycle dispatches second packet.
One of radio-frequency channel is switched on narrow beam 1-3 by base station in the first transmit cycle, according to the interface-free resources service condition of system, it is determined that being dispatched using narrow beam 1-3 interface-free resources after UE A, if narrow beam 1-3 interface-free resources also have residue, interface-free resources are distributed for other UE in narrow beam 1-3 coverage.At this point it is possible to which the dispatching priority according to the UE in narrow beam 1-3 coverage, is corresponding UE distribution interface-free resources.
In a wcdma system, interface-free resources can refer to code channel resource, and interface-free resources can refer to resource block in LTE system（Resource Block, RB ).
So, base station can determine the narrow beam for needing to launch data according to the position where the high UE of dispatching priority, then radio-frequency channel is switched to corresponding narrow beam, by the narrow beam to UE transmitting business data messages, the transmission of finishing service data.
By above-described embodiment it can be seen that, it can be realized within the same period by time-division beam switchover mechanism, using non-conterminous narrow beam service data information is sent to UE, and the signal covering of cell can just be completed by n narrow beam by only needing to n/2 radio-frequency channel, therefore, it is possible to avoid the reusability of interface-free resources in the interference between adjacent narrow beam, lifting cell, the power system capacity of cell is lifted, while Remote Radio Unit can also be reduced（Radio Remote Unit, RRU) etc. hardware quantity, reduce the cost of equipment, wherein, n is positive integer more than 1.

For example, in first half cycle, launching narrow beam by narrow beam antenna 1 and narrow beam antenna 4, now, radio-frequency channel 1 being switched at narrow beam antenna 1, launch narrow beam 1;Radio-frequency channel 2 is switched at narrow beam antenna 4, launches narrow beam 4.In the later half cycle, narrow beam is launched by narrow beam antenna 2 and narrow beam antenna 6, now, radio-frequency channel 1 is switched at narrow beam antenna 2, launches narrow beam 2;Radio-frequency channel 6 is switched at narrow beam antenna 6, launches narrow beam 6.
In practical application, the quantity of radio-frequency channel（That is n value）It can be adjusted according to cell target capacity.Radio-frequency channel 0 is fixed corresponding with antenna 0.Radio-frequency channel 1 to radio-frequency channel n just blunt can be switched to different narrow beams respectively according to demand, because narrow beam angle of coverage is small, antenna gain is higher, therefore, compared with carrying the radio-frequency channel of broad beam, the radio-frequency channel carrying narrow beam that power is relatively low can be used, to reduce hardware cost.
Beamsteering Unit 702 is radio-frequency switch array, is controlled by baseband processing unit 704.Baseband processing unit 704 periodically judges the positions of UE in the cell, determines the corresponding relation of UE and narrow beam antenna.When base station is needed to some UE transmission signal, Beamsteering Unit 602 selects a radio-frequency channel, and the antenna that the radio-frequency channel is accessed switches to narrow beam antenna corresponding with the UE.
Assuming that baseband processing unit 704 periodically judges the position of UE in cell, when it is determined that UE1 is in single narrow beam（Narrow beam 1) overlay area when, radio-frequency channel 1 is switched on narrow beam antenna 1 transmitting narrow beam 1;When it is determined that UE is in two narrow beams（Narrow beam 2 and narrow beam 3) overlapping region in when, baseband processing unit can be, but not limited to use following manner transmitting business data message：
For example, radio-frequency channel 1 is switched at narrow beam antenna 1 and narrow beam antenna 2, narrow beam is launched jointly using two narrow beam antennas（The service data information is carried in narrow beam）, now, radio-frequency channel needs hoisting power（For example, by transmitting power promotion 3dB).
In same transmit cycle, the quantity for the radio-frequency channel for reducing concurrent working that can be tried one's best according to cell capacity so as to reduce interference, and can reduce power consumption.
In the embodiment of the present invention, the corresponding radio-frequency channel of narrow beam（That is radio-frequency channel l ~ n) can be same
Identical interface-free resources are used in individual transmit cycle, wherein, in a wcdma system, interface-free resources can be that interface-free resources can be RB resources in a yard resource, LTE system.
