It holds consistent.
In embodiments of the present invention, further include：According to the RRC connection status, measurement period is set；Wherein,
When the RRC connection status is idle state, the measurement period of setting is the first measurement period；As the RRC
When connection status is connection status, the measurement period of setting is the second measurement period；The value of first measurement period is more than institute
State the value of the second measurement period.Here, different according to RRC connection status, the measurement period of setting is different, so that RRC connects
When connecing state difference, the beam angle for carrying out wave beam is different, and used measurement period is different.
Such as：When the RRC connection status of the link between terminal and base station be idle state when, can distribute beam angle compared with
Wide wave beam is carried out the transmission of the measuring signals such as channel quality measurement signal, synchronizing signal by the wave beam distributed, works as transmission
When the measurement period of measuring signal is relatively large, it is ensured that when moving, the frequency of measurement is lower, between wave beam for terminal
Switching the frequency reduces.When the RRC connection status of link between terminal and base station is connection status, it is relatively narrow beam angle can be distributed
Wave beam, the transmission of the measuring signals such as channel quality measurement signal, synchronizing signal is carried out by the wave beam that is distributed, is surveyed when sending
When the measurement period of amount signal is relatively small, it is ensured that terminal when moving, can timely switch on the wave beam communicated,
Improve data transmission efficiency.
It in practical applications, can be directly according to allocation strategy and beam configuration when carrying out the setting of beam configuration information

Row further illustrates.
It should be noted that in higher frequency spectrum, due to network node (such as base station) limited coverage area,
If being defined according to conventional cell, coverage radius of cell can be very small, therefore transmission receiving point can be generally introduced in 5G
The concept of TRP is equivalent to traditional base station, but in some cases in a TRP, a cell possible more than one
A TRP (being equivalent to base station) covers, but is combined by multiple TRP and covered, to increase the covering radius of cell.

When (connected state), using relatively narrow beam angle.Such as channel quality measurement letter is sent on the wave beam of the distribution
Number, the measuring signal of synchronizing signal, send measuring signal measurement period can be arranged it is shorter.
In an idle state, beam angle is wider, measurement period setting it is relatively longer, UE when moving, measurement
The frequency is lower, and the switching frequency also can be lower, to reach energy-efficient purpose.
In connected state, beam angle is relatively narrow, measurement period setting it is relatively shorter, UE when moving, Neng Gouji
When obtain the good correspondence wave beam of channel status.To improve the efficiency of data transmission.
Here, the beam configuration information of TRP can be in the form of bit by wide to terminal in the form of broadcast system information
It broadcasts.One terminal is when entering cell initial access, you can to obtain the beam configuration information of the TRP by system information.TRP
Beam configuration information can also be sent to terminal using special channel after terminal random access.
When the beam allocation information of TRP is as shown in table 1, wherein the wave beam of TRP has different beam angles, including：Wave
Beam width 1, beam angle 2 ... beam angle i.Wave beam in beam configuration information is arranged from big to small according to beam angle,
I.e. beam angle 1 corresponds to beam angle maximum, and beam angle i, corresponding beam angle are minimum.At this point, according to allocation strategy
The data business volume that the corresponding link of each beam angle is determined with beam configuration information, specifically, according to the transmission industry with terminal
Business data volume, to distribute corresponding beam angle.Wherein, as shown in table 1, M1, M2…Mi-1The big of business datum amount is indicated respectively
It is small, and M1, M2…Mi-1Value be sequentially increased.When obtaining the transmission services data volume between TRP and terminal, according to table 1
Beam allocation information carries out the distribution of wave beam, when business datum amount is smaller, the wider beampath of distribution, business datum amount compared with
When big, larger wave beam road is distributed.Such as：When the transmission services quantity for the link that TRP is communicated with terminal is X, and M2<
X<M1, it is determined that TRP communicated with terminal used in wave beam beam angle be beam angle 2.
1 beam allocation information of table
| Beam angle type | Transmission services data volume |
| Beam angle 1 | Less than M1 |
| Beam angle 2 | More than M1, it is less than M2 |
| 。。。 | 。。。 |
| Beam angle i | More than Mi-1 |
