The deformation of each operation.Communication means shown in Fig. 2 includes S210, S220 and S230.
S210, terminal determine main beam to and at least one for wave beam pair, main beam to each standby wave beam to including
The reception wave beam that the transmission wave beam and terminal that access network equipment uses use.
The wave beam can only be used to send information it should be understood that transmission wave beam described herein does not limit access network equipment, connect

Optionally, main beam to and at least one for wave beam centering wave beam to different cluster of channels can be corresponded to.
Millimeter wave channel has sub-clustering characteristic.Briefly, millimeter wave channel is made of several clusters, and each cluster is corresponding different
Azimuth and/or the elevation angle and/or energy, when constructing channel, the cluster of channel is evenly distributed on the range at azimuth and the elevation angle
It is interior, it is believed that spacing is larger between different clusters on space angle.Each cluster can be extended to several sub- diameters, and sub- diameter is gathered in
Around the angle of cluster, laplacian distribution is usually obeyed, strong with diameter correlation sub- in cluster, space angle is close and close
(modulus value that ability can correspond to the complex coefficient multiplied when channel).When channel is blocked, due to the distribution characteristics of cluster spatially,
Lead to the sub- diameter in same cluster often while blocking, the sub- diameter in different clusters will not be blocked simultaneously, this just makes according to sub-clustering spy
Property to wave beam grouping can play the requirement being switched fast.

As shown in figure 3, S210 may include S211 to S214.
S211 terminal carries out beam search, obtains multiple wave beams pair, each wave beam is to the hair used including access network equipment
The reception wave beam for sending wave beam and terminal to use.
Below by taking access network equipment is base station as an example, a kind of embodiment of beam search is introduced, it can in the embodiment
To include three steps, step 1 is distributed as to step 3.
Step 1, base station successively use different wave beam (T1, T2..., TCt) to receiving end transmission reference signal, terminal is adopted
It is received with omnidirectional, and the energy for the reference signal that successively detection different beams are sent, record is wherein with the wave beam of peak energy
(Tp1, Tp2..., Tpi) and feed back to base station.
Wherein, the wave beam with peak energy refers to that energy is greater than the wave beam of all adjacent beams.For example, base station uses sequence
When number sending reference signal for 10 wave beam, the energy for the reference signal that terminal receives, than base station using serial number 9 and 11
When wave beam sends reference signal, the energy of the reference signal of expected end receiver is all big, then the wave beam of serial number 10 has peak value
The wave beam of energy.
Step 2, terminal successively use different wave beam (R1, R2..., RCr) different reference signals, base are sent to base station
It stands and is received using omnidirectional, and the energy of the reference signal of one-time detection different beams transmission, record wherein have peak energy
Wave beam (Rp1, Rp2..., Rpj) and feed back to terminal.
The definition of wave beam in step 2 with peak energy, the definition class with the wave beam in step 1 with peak energy
Type, details are not described herein again.
Under normal conditions, at least one in pi and pj is greater than 1.
Step 3, base station successively use the wave beam with peak energy that terminal is fed back in step 1 to send to terminal and refer to
Signal, terminal successively uses the wave beam with peak energy of base station feedback in step 2 to receive reference signal, and measures each
The Reference Signal Received Power (reference signal receiving power, RSRP) of secondary received reference signal.Eventually
The wave beam that end receives the wave beam of reference signal and base station sends the reference signal forms a wave beam pair, and terminal measures reference letter
Number obtained RSRP is properly termed as the RSRP of the wave beam pair.
Terminal obtains pi × pj RSRP after pi × pj measurement.This pi × pj RSRP corresponds to pi × pj wave
Beam pair.In order to which subsequent descriptions are convenient, pi × pj is denoted as K, K is the integer greater than 1.
As its name suggests, the wave beam communicated is used directly to after the completion of main beam is to beam search is referred to, between base station and terminal
It is right；In the case that standby wave beam is to referring to main beam to communication failure, do not have to re-start in the prior art between base station and terminal
Beam search process, and be used to the wave beam pair that communicates.
S212, terminal is by multiple wave beams to multiple wave beams are divided into group, and multiple wave beams are to wave beam different in group to group pair
Answer different cluster of channels.A kind of example of this multiple wave beam pair is K wave beam pair obtained in S211.
As shown in figure 4, terminal is by multiple wave beams to being divided into multiple wave beams in a kind of implementation of group, with wave beam pair
The serial number for the wave beam (for example, with the corresponding transmission wave beam of reference signal of peak energy in S210) that middle access network equipment uses
For abscissa, the wave beam used with wave beam centering terminal is (for example, with the corresponding reception of reference signal of peak energy in S210
Wave beam) serial number ordinate, by this multiple wave beam to being mapped in two-dimensional coordinate figure.
In Fig. 4, oblique line grid indicates this multiple wave beam pair.
Then according to the Euclidean distance between each oblique line grid by this multiple wave beam to being divided into multiple wave beams to group.Such as
Described in Fig. 4, three wave beams of upper left are divided into a wave beam to group to group, and multiple wave beams on the right are to being divided into a wave beam
To group, three wave beams of lower section are to being divided into a wave beam to group.
It is of course also possible to the serial number for the wave beam that access network equipment is used is as ordinate, the wave beam that terminal is used
Serial number is as abscissa, then by this multiple wave beam to being mapped in two coordinate diagrams, further according to each oblique of expression wave beam pair
Euclidean distance between line grid is by this multiple wave beam to being divided into multiple wave beams to group.
For terminal by multiple wave beams to multiple wave beams are divided into in another implementation of group, terminal can be according to each
Wave beam centering, the wave beam that access network equipment uses leave angle and the angle of arrival of wave beam that terminal uses, by multiple wave beams to point
It is multiple wave beams to group.
Wherein, the wave beam that access network equipment uses leaves angle and can be calculated by following formula:
Leave angle=(serial number for the wave beam that access network equipment uses) * 360 °/access network equipment wave beam sum
The angle of arrival for the wave beam that terminal uses can be calculated by following formula:
Leave angle=(serial number for the wave beam that terminal uses) * 360 °/terminal wave beam sum
For example, can leave angle when leaving angle and being respectively 0 °, 80 °, 100 °, 130 °, 150 ° and 190 ° for this 6 and be divided into 4
Group.First group includes 0 °, and second group includes 80 ° and 100 °, and third group includes 130 ° and 150 °, and the 4th group includes 190 °.
In other words, 0 ° of corresponding transmission wave beam is the first transmission wave beam group, 80 ° of corresponding transmission wave beams and 100 ° of correspondences
Transmission wave beam be second to send wave beam group, 130 ° of corresponding transmission wave beams transmission wave beam corresponding with 150 ° is to for third wave beam
Group, 190 ° of corresponding transmission wave beams are the 4th transmission group.
It for another example, can be by this 6 angle of arrival when angle of arrival is respectively 0 °, 20 °, 100 °, 130 °, 180 °, 190 ° and 260 °
It is divided into 3 groups.First group includes 0 ° and 20 ° one group, second group includes 100 ° and 130 °, and third group is including 180 ° and 190 °, the 4th
Group includes 260 °.
That is, 0 ° and 20 ° corresponding reception wave beam is the first reception wave beam group, 100 ° and 130 ° of corresponding received waves
Beam is the second reception wave beam group, and 180 ° and 190 ° corresponding reception wave beams are that third receives wave beam group, 260 ° of corresponding received waves
Shu Wei tetra- receives wave beam group.
It is picked out it is then possible to successively send the maximum transmission wave beam of RSRP respectively included in wave beam group for four,
Successively the maximum reception wave beam of RSRP respectively included in wave beam group is received by four to pick out.
It finally will be singled out the four transmission wave beams come and receive wave beam, successively form wave beam pair according to the size of RSRP.
Specifically, in select four transmissions wave beam in the maximum transmission wave beam of RSRP and select four receptions wave beam
The maximum reception wave beam of RSRP forms a wave beam pair, successively determines remaining three wave beams pair.
S213, terminal is by the maximum wave beam of multiple wave beam centering RSRP to as main beam pair.
For example, the K maximum wave beam of wave beam centering RSRP that S211 is obtained is to as main beam pair.
S214, terminal is by multiple wave beams to not including each wave beam of main beam pair in group to the maximum wave beam of RSRP in group
To as standby wave beam pair, obtain it is described at least one for wave beam pair.
For example, being known as the first wave beam to group to group to the wave beam in group including main beam pair for obtained multiple wave beams are divided
When, terminal can from this multiple wave beam in group except the first wave beam to the wave beam in addition to group to choosing standby wave beam pair in group.
For example, terminal can by except the first wave beam to each wave beam in addition to group to the maximum wave beam of RSRP in group to selecting
Out as standby wave beam pair.In this way, the total quantity of main beam pair and standby wave beam pair is identical as quantity of the wave beam to group.
Alternatively, after executing S211 and S212, can first by each wave beam to the maximum wave beam of RSRP in group to selecting
Out, then will be singled out come the maximum wave beam of wave beam centering RSRP to as main beam pair, will be singled out come wave beam centering
Other wave beams to as standby wave beam pair.
S220, terminal to access network equipment send the first information, the first information be used to indicate main beam to and at least one
Standby wave beam pair.
Correspondingly, access network equipment receives the first information.
In other words, in the first information that terminal is sent to access network equipment, in addition to indicating that main beam to other than, also indicates
Standby wave beam pair.When this makes the interrupted communication link of main beam pair, access network equipment can be searched without re-starting a wave beam
Rope, but standby wave beam can be used to communicate with terminal.
It may include the serial number of the transmission wave beam in main beam and the serial number for receiving wave beam in the first information, and including every
The serial number of the transmission wave beam of a standby wave beam centering and the signal for receiving wave beam.
S230, terminal receive the send wave that access network equipment uses main beam centering using the wave beam that receives of main beam centering
The information that beam is sent.Wherein, when at least one spare wave beam is to interrupted communication link for main beam pair, terminal is set with access net
The wave beam pair that standby communication uses.
As shown in figure 5, can also include S240 after S230.S250 and S260.
S240, terminal determine the interrupted communication link of main beam pair.
For example, terminal receives the send wave that access network equipment uses main beam centering using the wave beam that receives of main beam centering
When the information that beam is sent, if the ability of reception, which is less than or equal to, receives energy threshold, terminal can determine main beam to leading to
Believe link terminal.The size for receiving capability threshold value can be set according to demand.
S250, terminal send the second information to access network equipment, and the second information is used to indicate through at least one for wave beam
The first of centering is for wave beam to communicating.
Correspondingly, access network equipment receives the second information.
It may include first in second information for the serial number of the transmission wave beam of wave beam centering and the serial number of reception wave beam.
S260, terminal use the first spare wave beam pair using first for the reception wave beam reception access network equipment of wave beam centering
In send wave beam send information.
If standby wave beam is to regard to only one, this is for wave beam to i.e. as the first wave beam pair.
If standby wave beam is to be multiple right, as shown in fig. 6, can also include S242 and S244 before S250.
S242, terminal measure the RSRP of each wave beam pair of multiple standby wave beam centerings.In other words, terminal re-measures each
The RSRP of standby wave beam pair.
For example, access network equipment uses the transmission wave beam of this multiple standby wave beam centering to send reference signal to terminal respectively,
Terminal receives the reference signal using the reception wave beam of standby wave beam centering belonging to the transmission wave beam, and measures the reference signal
RSRP.Finally, terminal measurement obtains and standby wave beam RSRP identical to quantity.
S244, terminal by the maximum wave beam of multiple standby wave beam centering RSRP to as first for wave beam pair.
S242 and S244 make terminal communicated with access network equipment used in first for wave beam to for current com-munication environment
Lower RSRP best wave beam pair, so as to improve communication quality.
Optionally, terminal and access network equipment by first for wave beam to communicating when, access network equipment can be by send wave
Beam is adjusted to first for the transmission wave beam of wave beam centering, and terminal is adjusted to first for wave beam is received for the received wave of wave beam centering
Beam.
It in one possible implementation, does not include S242 and S244, terminal is according to S210 before S250
It is middle to measure the obtained RSRP of each standby wave beam pair, will standby wave beam to sequence, and after sorting the maximum standby wave beam of RSRP to work
For first for wave beam pair.
Optionally, if terminal determines first for the interrupted communication link of wave beam pair, terminal is again big by RSRP times after sequence
Standby wave beam for wave beam pair, and repeat S250 and S260 to as first.Until can be normal between terminal and access network equipment
Communication.
If all standby wave beams are to cannot all make normal communication between terminal and access network equipment, terminal can be again
Carry out beam search.
Optionally, access network equipment is adjusted to first for wave beam is sent for the transmission wave beam of wave beam centering, and terminal will connect
Receive after wave beam is adjusted to first for the reception wave beam of wave beam centering, terminal and access network equipment can beam direction to oneself into
Fine tuning, so that the RSRP of wave beam pair adjusted is bigger.
For example, it is spare that the beam direction of terminal is first fixed as first when the transmission wave beam of access network equipment is finely adjusted
