Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
When using beamforming technologies, in order that transmitting terminal can cover whole region, it is necessary to 360 degrees omnidirection
Transmitting downlink spatial synchronizing signal (includes spatial synchronization training sequence (TS, Training Sequence), may also have system
Broadcast message etc.).Few in antenna number, when the wave beam of formation is few, transmitting terminal can be with all wave beams of one-off scanning, but antenna number is more
Formed wave beam it is more when, be limited to the ability and power of transmitting terminal, it is impossible to the whole cell of one-off scanning, it is necessary to the cycle circumferentially enter
Traveling wave beam scanning.
Referring to Fig. 1, in multi-antenna systems, due to the multi-beam that multiple antennas is formed, the energy force and work of transmitting terminal is limited to
Rate, it is difficult to disposably scan all wave beams, it is possible to using the method for Grouping scan, i.e. in a sweep time, only sweep
Part wave beam, 2 wave beams of single pass as shown in Figure 1 are retouched, until scanning through all wave beams.The Integral Thought of the present invention

Wave beam divides in a group, is then scanned by the traffic load pro rate different time, ensures each group run-down.
Embodiment one
Referring to Fig. 2, it illustrates a kind of wave beam Grouping scan method provided in an embodiment of the present invention, methods described can wrap
Include：
All wave beams of S101, transmitting terminal according to needed for the traffic load of each wave beam will cover whole cell are divided
Group, obtain at least one wave beam group.
It should be noted that before step S101, transmitting terminal is it needs to be determined that it covers all ripples needed for whole cell
The lower limit wave beam group number of beam packet, therefore, the present embodiment also includes：
S100：The width of each wave beam formed according to the transmitting terminal can be formed with the transmitting terminal at each moment
Maximum numbers of beams, it is determined that covering the group number lower limit that all wave beams needed for whole cell are grouped to the transmitting terminal.
Specifically, referring to Fig. 3, step 100 includes step S1001 and S1002:
S1001, determined according to the width for each wave beam that transmitting terminal is formed transmitting terminal cover whole cell needed for wave beam
Sum.
It should be noted that because in multiple-wire system, each wave beam of beam forming has with certain width, in order that
Transmitting terminal covers whole region, and the wave beam that transmitting terminal is formed, which needs to form 360 degree of coverage rate, could cover whole region.Cause
This, it is assumed that the width of each wave beam is θ, then the wave beam total number N formed required for transmitting terminal is individual for N=360/ θ.
For example, it is assumed that the transmitting terminal of multiaerial system, each beam angle θ of beam forming is 15 degree, in order that transmitting
End covering whole region, transmitting terminal need N=24=360/15 wave beam to cover whole region.
S1002, all wave beams sum according to needed for transmitting terminal covers whole cell are with transmitting terminal in each moment institute energy
The maximum numbers of beams of formation, calculate the group number lower limit of packet needed for all wave beams.
It should be noted that due to the emissivities limitation of transmitting terminal and the power limit of transmitting terminal, transmitting terminal is every
The individual moment can be only formed the wave beam that M beam angle is θ, and this M wave beam, which is less than required for transmitting terminal covers whole cell, to be formed
N number of wave beam, the most group number of packet needed for all wave beams, that is, it is N/M to organize number lower limit, in actual packet, the group divided
Number needs to be more than or equal to N/M.
Exemplary, due to being limited to the ability and power of transmitting terminal in actual beam forming process, transmitting terminal is each
Moment can be only formed the wave beam that 8 beam angles are 15, and therefore, the group number lower limit of packet is N/M=24/8 needed for all wave beams
=3.
In order that transmitting terminal can cover whole cell, transmitting terminal can be by way of the time-division, the shape different at the time of
Into the wave beam of different directions, can thus transmitting terminal be set to cover whole region.Exemplary, in moment T1, transmitting terminal
M can be formedThe wave beam of first direction, M can be formed in moment T2
The wave beam of second direction, in moment Tk, M can be formedThe wave beam in kth direction.Therefore using upper
State time division way,This k direction
The region that can just cover where 360 degree of whole orientation of set.By above-mentioned ripple is formed using time division way in transmitting terminal
Beam, all wave beams that the wave beam that transmitting terminal is formed is formed altogether at this k moment can just cover its administrative 360 degree complete
Portion region.The wave beam number that above-mentioned each moment is formed can be less than or equal to M, the wave beam number that each moment is formed be needed full
Foot covers whole region within the scan period.
After step sloo, specifically, including step S1011 to S1013 referring to Fig. 4, step S101：
S1011, each ripple of traffic load calculating according to each user under the number of users under each wave beam and the wave beam
The traffic load of beam.
It should be noted that the traffic load for calculating each wave beam is in order to which wave beam is grouped according to traffic load,
And the foundation as wave beam group distribution sweep time.
S1012, all wave beams are carried out by sequence from big to small according to the traffic load of each wave beam, obtained according to business
Beam sequences after load sequence.
It is to be appreciated that after the traffic load of each wave beam is calculated, by the traffic load of each wave beam according to by big
Arranged to small order, it is possible to obtain the wave beam after sequence.
S1013, the beam sequences after being sorted according to traffic load are grouped successively according to traffic load is descending,
Obtain the wave beam group after packet；Wherein, the numbers of beams in each packet can be formed most less than or equal to described at each moment
Big numbers of beams；Wave beam group quantity after the packet is more than or equal to the group number lower limit of packet needed for all wave beams.
It is exemplary, it is assumed that actual packet is K group, and the wave beam after being sorted according to traffic load is divided into according to having arranged
The descending order arranged is grouped successively, is always divided into K group, wherein, K, which is more than or equal to needed for all wave beams, to be grouped
Most group number be N/M.The P1 (P that traffic load is maximum1≤ M) individual beam allocation is big traffic load time to first group
P2(P2≤ M) individual beam allocation to second group, is carried out successively, until being divided into K group.
Wave beam is grouped specially in above-mentioned steps S1002：8 maximum wave beams of traffic load are divided into one
Group, it is group1 to make the group, 8 big wave beams of traffic load time is divided into one group, it is group2 to make the group, remaining 8 ripples
Shu Weiyi groups, it is group3 to make the group.
S102, transmitting terminal determine each wave beam group according to the traffic load state of each wave beam group within the single scan period
The corresponding sweep time being assigned to.
Specifically, include step S1021 and S1022 referring to Fig. 5, step S102：
The traffic load of each wave beam of S1021, transmitting terminal in each wave beam group calculates the business of each wave beam group
Load.
Specifically, the total business for calculating the wave beam group according to each beam service load can of each wave beam group is born
Lotus, three packets to above-mentioned S1013, the total business that group1 is calculated according to the traffic load of the 8 of group1 wave beams are born
Lotus is S1, and the total business load of group2 8 wave beams is S2, and the total business load of group3 8 wave beams is S3.
S1022, transmitting terminal are carried out the single scan period to each wave beam group according to the total business load of each wave beam group
Sweep time distributes, it is determined that the traffic load of the sweep time being assigned to corresponding to each wave beam group and each wave beam group is into positive
Close.
It is to be appreciated that carry out time distribution according to traffic load ratio, during bigger the distributed scanning of traffic load
Between it is longer.For example, it is T to make a scan period, can according to the traffic load of the above-mentioned steps S1021 each wave beam groups calculated
So that the sweep time that each wave beam group is distributed is calculated, group1 sweep time is t1=ceil (T × (S1/S1+S2+
S3)), group2 sweep time is t2=ceil (T × (S2/S1+S2+S3)), group3 sweep time are t3=T-t1-
t2.Wherein, ceil represents to return to the smallest positive integral value more than or equal to expression formula.
It should also be noted that, in order to ensure each wave beam group run-down, for the distribution of each wave beam group scanning when
Between can not be 0 or negative value.In the examples described above, if the sweep time t3 for calculating group3 is 0 or negative value, then need weight
New adjustment time, ensure each beam scanning once.Scan period T can not be set too big, it is ensured that UE uplink synchronous.
S103, transmitting terminal are scanned according to the sweep time that each wave beam group is correspondingly assigned to each wave beam group.
After the time of each wave beam group is assigned, transmitting terminal according to the wave beam group and beam scanning time distributed come
Beam scanning is carried out, simultaneously, it is ensured that each wave beam group can be sent within a scan period once to be broadcasted, and is realized comprehensive
Covering.
