Wherein, can be that the reference signal power value that continuous several times measure is less than threshold value in multiple measurement results, it can also
It is that the discontinuous reference signal power value repeatedly measured is less than threshold value.
When primary beam meets above-mentioned switching condition to upper reference signal power value, user equipment 10 can determine wave beam pair
Information, wherein wave beam are to there are two types of information：
The first, wave beam to information include the primary beam to corresponding wave beam to information：
At this point, the user equipment 10 can not determine alternative target wave beam pair, it is unsuitable that the user equipment 10 determines
Wave beam to can alternately object beam pair.
User equipment 10, which can receive several transmitter units (including former transmitter unit), believes the reference of transmission by wave beam
Number, and the performance number of reference signal is detected, it, can be by the wave if wave beam is more than threshold value to upper reference signal power value
Beam is to alternately object beam pair.If wave beam is not more than threshold value to upper reference signal power value, the wave beam is to not as standby
Select object beam pair.If being more than the wave beam pair of threshold value currently without reference signal power value, when the reference signal work(of primary beam pair
Rate value meets switching condition, and when the communication quality between user equipment 10 and former transmitter unit declines, user equipment 10 does not report
Alternative target wave beam is to corresponding wave beam to information to macro base station 20.
Second, wave beam to information include the primary beam pair and the alternative target wave beam to corresponding wave beam to letter
Breath.
At this point, the user equipment 10 can determine that alternative target wave beam pair, the determination of the user equipment 1 have suitable wave
Beam is to can alternately object beam pair.
Alternative target wave beam is to that can be some or all of following wave beam centering：
The corresponding spare wave beam pair of the user equipment 10；
Reference signal power value is more than the wave beam pair of threshold value.
The user equipment 10 can be by the pre-stored spare wave beam of the user equipment 10 to as the alternative mesh
Mark wave beam pair；Reference signal power value can be more than the wave beam of threshold value to as the alternative target wave by the user equipment 10
Beam pair；The corresponding spare wave beam pair of the user equipment 10 and reference signal power value can be more than threshold by the user equipment 10
The wave beam of value is to as the alternative target wave beam pair.
Three kinds of situations are introduced below：
Situation one, the user equipment 10 can be by the corresponding spare wave beams of the user equipment 10 to as described alternative
Object beam pair；
User equipment 10 can prestore the wave beam pair used the when of being communicated between transmitter unit and user equipment 10,
By these wave beams to as spare wave beam pair, when the reference signal power value of primary beam pair meets switching condition, user equipment 10
When communication quality between former transmitter unit declines, by spare wave beam to alternately object beam pair and by corresponding wave beam
To information reporting to macro base station 20.
Wherein, spare wave beam is to being set with user according to several transmitter units (including former transmitter unit) by user equipment 10
Wave beam determines the performance number of upper reference signal between standby 10；User equipment 10 can receive transmitter unit and pass through wave beam pair
The reference signal of transmission, and the performance number of reference signal is detected, if wave beam it is higher to upper reference signal power value or
It, can be by the wave beam to as spare wave beam pair when more than certain threshold value, it should be noted that spare wave beam is to can be according to ginseng
The detection for examining the performance number of signal carries out real-time update.
Reference signal power value can be more than the wave beam of threshold value to as described alternative by situation two, the user equipment 10
Object beam pair；
User equipment 10, which can receive several transmitter units (including former transmitter unit), believes the reference of transmission by wave beam
Number, and the performance number of reference signal is detected, it, can be by the wave if wave beam is more than threshold value to upper reference signal power value
Beam is to alternately object beam pair.When the reference signal power value of primary beam pair meets switching condition, user equipment 10 and original
When communication quality between transmitter unit declines, reference signal power value is more than the wave beam of threshold value to alternately object beam
Pair and by corresponding wave beam to information reporting to macro base station 20.
Situation three, the user equipment 10 can be by the corresponding spare wave beam pair of the user equipment 10 and reference signal work(
Rate value is more than the wave beam of threshold value to as the alternative target wave beam pair；
User equipment 10, which can receive several transmitter units (including former transmitter unit), believes the reference of transmission by wave beam
Number, and the performance number of reference signal is detected, it, can be by the wave if wave beam is more than threshold value to upper reference signal power value
Beam is to alternately object beam pair；When the reference signal power value of primary beam pair meets switching condition, user equipment 10 and original
When communication quality between transmitter unit declines, reference signal power value is more than the wave beam pair of threshold value and pre-stored standby
With wave beam to alternately object beam pair and by corresponding wave beam to information reporting to macro base station 20.
It should be noted that alternative target wave beam is to either one or more.
After user equipment 10 determines wave beam to information, by the wave beam to information reporting to macro base station 20, so that institute
It states macro base station 20 and object beam pair is determined to information according to the wave beam.
The wave beam include but not limited to wave beam to corresponding transmitter unit information, wave beam to instruction information to information and
Performance number of the wave beam to upper reference signal.The form of information is reported, can be a signaling for including N number of field, each field
A wave beam is written to corresponding wave beam to information；If as shown in Fig. 2, the number of alternative target wave beam pair be one, signaling
In include two fields；As shown in figure 3, if the number of alternative target wave beam pair is N number of, field number is N+1 in signaling.
Wave beam is used to indicate instruction information the identification information of wave beam pair, to distinguish different wave beams pair.
It should be noted that the wave beam is to including that wave beam can be in order to macro to the performance number of upper reference signal in information
Base station 20 determines object beam pair according to the information, if the wave beam has work(of the wave beam to upper reference signal to not including in information
Rate value, macro base station 20 can determine object beam according to testing result to the alternative target wave beam reported to being detected in real time
It is right；The mode wherein detected, there are many kinds, such as can send detection instruction to user equipment 10, are carried out by user equipment 10
Detection, then testing result is reported to macro base station 20；Equipment of the detection instruction to being detected dedicated for wave beam can also be sent, by
Equipment dedicated for wave beam detection is detected, then testing result is reported to macro base station 20.
Since the signaling is that reference signal power value between user equipment 10 and former transmitter unit meets switching condition,
Namely there are what is sent when choking phenomenon, which can be referred to as to BI (blockage information block information) letter
It enables.
Need to illustrate when, when macro base station 20 is low frequency macro base station 20, carried out between user equipment 10 and macro base station 20
Communication belong to LF communication, it is more difficult to the influence of phenomenon blocked, also can be more smoothly by wave beam to information reporting
To macro base station 20.
And since high-frequency communication has many advantages, such as, so can be directly high-frequency emission list with the communication of user equipment 10
Member, namely former transmitter unit are high-frequency emission unit, and the alternative target wave beam is height to corresponding alternative target transmitter unit
Frequency transmitter unit.
Wherein, low frequency refers to the frequency range less than 6GHz, and high frequency refers to the frequency range higher than 6GHz.
After macro base station 20 receives wave beam that user equipment 10 reports to information, target is determined to information according to the wave beam
Wave beam pair；
The macro base station 20 is according to the object beam to switching over operation.
According to wave beam to information, macro base station 20 can make corresponding processing.
The first, wave beam to information include the primary beam to corresponding wave beam to information：
Since the corresponding wave beam without alternative target wave beam pair in the information that reports at this time can be true to information, macro base station 20
Surely without suitable wave beam to alternately object beam pair；
The macro base station 20 determines that the wave beam of the macro base station 20 and the wave beam of user equipment 10 are object beam pair, described
Macro base station 20 is used as target transmitting unit；
In order to ensure that user equipment 10 can be with normal communication, macro base station 20 can be connect with user equipment 10, by macro base station
20 wave beam and the wave beam of user equipment 10 are as object beam to being used for transmission data, it should be noted that due to macro base station
20 be low frequency macro base station 20, and only there are one wave beams for macro base station 20.
In such cases, macro base station 20 may be used following three mode and switch over operation：
1, the primary beam is transmitted to the primary beam to corresponding by the macro base station 20 to corresponding wave beam to information
Former transmitter unit；
The original transmitter unit can about be scheduled on due to only receiving primary beam to corresponding wave beam to information and only receive former wave
Beam to corresponding wave beam to information when, by macro base station 20 be used as target transmitting unit, it is described original transmitter unit can receive
Switching-beam pair after information, and notifying user equipment 10 stops being communicated with former transmitter unit, starts to carry out with macro base station 20
Communication.

The original transmitter unit receives primary beam pair and the object beam to corresponding wave beam to information, it may be determined that will
Macro base station 20 is used as target transmitting unit, the original transmitter unit can after receiving information switching-beam pair, and notify to use
Family equipment 10 stops being communicated with former transmitter unit, starts to be communicated with macro base station 20.
Second, the wave beam to information include primary beam pair and alternative target wave beam to corresponding wave beam to information：
If the number for the alternative target wave beam pair that user equipment 10 reports is one, macro base station 20 can be by the alternative mesh
Wave beam is marked to being determined as object beam pair, an object beam can also be set to reference signal power value threshold value, if this is alternative
Object beam is less than object beam to reference signal power value threshold value, then not by the alternative target wave beam to reference signal power value
To being determined as object beam pair, and inform that user equipment 10 can not switch, if the alternative target wave beam is to reference signal power value
Higher than object beam to reference signal power value threshold value, then by the alternative target wave beam to being determined as object beam pair.
If the number for the alternative target wave beam pair that user equipment 10 reports is multiple, macro base station 20 can be by alternative target
The wave beam maximum wave beam of centering reference signal power value is to that for object beam pair, can also set an object beam to reference to believing
Number performance number threshold value, if multiple alternative target wave beams are below object beam to reference signal power value to reference signal power value
Threshold value does not know object beam pair then, and informs that user equipment 10 can not switch, if there are alternative target wave beams to reference signal
Performance number higher than object beam to reference signal power value threshold value, then will be above object beam to reference signal power value threshold value and
The maximum alternative target wave beam of reference signal power value is to being determined as object beam pair.
Primary beam pair and object beam are transmitted to primary beam to correspondence by the macro base station 20 to corresponding wave beam to information
Former transmitter unit and the corresponding target transmitting unit of the object beam so that former transmitter unit and target transmitting unit switching
Wave beam pair.
It should be noted that if the object beam determined is former transmitter unit, Ye Jiyuan to corresponding target transmitting unit
