Increase beam management modules in user plane, specific beam management modules can be separately existed in user plane, can also and be used
Other functional modules in family face are merged.
It is illustrative below by the example in concrete application.
This application example illustrates by taking LTE system as an example, as shown in Figure 6.The network architecture be centralized unit (CU) and
The level framework of distribution unit (DU) two, wherein MAC functions are located in CU, and all functions of physical layer are located in distribution unit.This
The beam management functions being previously mentioned in application example are located at the layer 2 of user plane protocol framework：In MAC layer, namely beam management work(
It can be located in centralized unit CU.
In the present embodiment, the first beam management modules are located in MAC layer, can be separately as MAC One function
It module, can also merge with other functions of MAC layer, for example be merged with scheduling feature, i.e., manage beam as scheduling feature
A part.
The beam measures submodule, for obtaining the beam measurement amount related to channel quality.
The beam measurement amount related to channel quality, including following one or two kinds of above measurement amount are any
Combination：CQI (channel quality instruction, Channel Quality Indicator), PMI (Precoding Matrix
Indicator, pre-coding matrix instruction), RI (Rank Indication, order instruction), RSRP (Reference Signal
Received Power, Reference Signal Received Power) etc..Certainly, the measurement amount can also be other related contents, specifically
Option and installment can be carried out according to actual conditions, the embodiment of the present invention is not limited herein.
Wherein, the specific related signaling for performing measurement can be issued by chain of command signal deployment, and LTE measurement is related at present
Signaling be all by RRC (Radio Resource Control, wireless heterogeneous networks) signal deployment issue (RRC signaling for control
Plane signaling processed)；
Base station side and the user plane of end side can support the function, be implemented as：Beam measurements are issued by base station
After instructing terminal, terminal to carry out channel quality measurement, the measurement amount of acquisition is reported into base station.For example MAC CE can be passed through
Transmitting signaling downwards measurement configuration, while increase the signaling that beam measurements report in the user plane of end side.
Alternatively embodiment, the signaling of increase instruction beam measurements, base station side and end side in user plane
The function is supported, is implemented as：Beam measurement instructions are issued to terminal by base station, after terminal carries out channel quality measurement,
The measurement amount of acquisition is reported into base station.
The beam dispatches submodule, for prestore network parameter and the beam surveys obtained according to the parameter acquisition module
The beam measurement amount related to channel quality that quantum module obtains sends beam dispatch commands to transmitter unit；
Described that multiple beam are scheduled, a kind of situation is, in following NR systems, each RAN (Radio Access
Network, wireless access network) side and UE sides all there may be multiple beam, for example the disposal ability of RAN sides cannot be guaranteed once
The directive beam of institute can be launched, and (360 degree, may share tens beam, and disposal ability is limited can only once send out such as 8
It is individual), this will be related to transmitting which 8 every time, how be grouped, and dispatch the problem of which is grouped every time, and this is that scheduling may relate to
One side；
Another situation is that may there was only a user under a beam, it is also possible to have multiple users, user is adjusted
Degree is equal to and beam is scheduled.Therefore the issue of priority for the beam being related in dispatching, may also consider in scheduling
Interference coordination (beam in some directions needs to stagger, it is impossible to clashes) etc.；
In embodiments of the present invention, base station side has multiple beam, is likely to from several to individual beam up to a hundred；End side
There may be multiple beam, but quantity is typically more much less than base station side.It can be seen that in future communication systems, base station side may be sent
Multiple beam, and end side may also have multiple beam and be directed at them, beam turns into a kind of spatial domain resource, therefore how to select
Beam and one of the required content of (scheduled transmission moment and tranmitting frequency) as beam management how is scheduled to beam.
The beam monitorings and switching submodule, beam signal quality are monitored for obtaining, and measure according to beam
The channel quality measurement amount of submodule measurement, when decline suddenly occurs in signal, switching command is sent to transmitter unit, will appear from
Terminal corresponding to the beam of signal fadeout is switched to other beam；
Monitored on beam, in future communication systems, high band causes signal due to its wireless channel environment
The situation for occurring declining suddenly is more frequent, it is therefore desirable to which beam signal quality is timely monitored so that unexpected
Deep fade occur when, can carry out in time beam switching or other processing and ensure performance and do not suffer a loss；
Switch on beam, in future communication systems, high band causes signal due to its wireless channel environment
The situation for occurring declining suddenly is more frequent, therefore for terminal, may be ready to switch to other beam
This unexpected deep fade is resisted, therefore user plane needs to increase beam switchings related auxiliary signaling and relevant treatment function
(including handover decisions, switching prepare, and switching is implemented etc.).
The method that one of which specifically switches can be bear split (carrying segmentation) mode.Shown in reference picture 7, it is
The bear split configuration diagrams of LTE dual links.The method specifically switched is：When a certain link breaks down, can cut
Change on another link not broken down.
As shown in fig. 7, so-called bear split, are：PDCP points are Liang Ge branches, and MeNB (Master walk in a branch
ENB, master base station), SeNB (Secondary eNB, secondary base station) walks in a branch, and Liang Ge branches backup each other.Anchor point is exactly
PDCP in MeNB, that is to say, that do not have PDCP layers in SeNB.S1 is that (Radio Acess Network, wirelessly connect RAN in figure
Network) interface between CN (Core Network, core net).
The beam cooperations submodule, the network parameter that prestores for being obtained according to parameter acquisition module send beam cooperations
Transmitter unit, and the interference parameter between the beam for measuring submodule acquisition according to beam are instructed, sends beam interference association
Instruction is adjusted to arrive transmitter unit；
Cooperation and interference coordination between Beam can be different according to the difference of framework, for example can include following two feelings
Condition：
The first situation：The CoMP technologies in similar LTE can be used, several cooperation beam send identical data, increase
The reliability of strong data receiver；
Second of situation：Can be by the way of CS/CB be disturbed and evaded, when scheduled (the occupancy portions of UE on a beam
Point resource), if strong jamming (being referred to as strong jamming beam) be present in the UE of the beam, then can set the part of the beam/
