With reference to the above-mentioned description to technical solution of the present invention, the embodiment of the present invention provides following for the realization of step 103
Two kinds of concrete implementation modes, respectively as shown in Figure 3 and Figure 4.
Method flow as shown in Figure 3 is applied to the information transmission between the downlink access point and multi-upstream access point
Speed is higher than under conditions of predetermined threshold value, and on this condition, the transmission delay between multi-upstream access point and downlink access point can be very
Low, therefore, the information that downlink access point is forwarded to by multi-upstream access point may be considered in real time, and such downlink access point can
With direct subsequent treatment is carried out using the information got.
Wherein, the setting principle of predetermined threshold value, can be according to networking configuration and base to ensure the real-time of information transmission
The empirical value for the transmission delay between access point of standing is set.
This method flow specifically includes：
A1031, the downlink access point are demodulated the descending channel information.
A1032, the downlink access point carry out down the user input equipment according to the descending channel information after demodulation
Row scheduling.
Above flow is regarded as downlink access point and directly receives user input equipment feedack, it implements stream
Journey can follow the common flow of the prior art, and the embodiment of the present invention does not do this excessive description.
Method flow as shown in Figure 4 is applied to the information transmission between the downlink access point and multi-upstream access point
Speed is not higher than under conditions of predetermined threshold value, on this condition, the transmission delay meeting between multi-upstream access point and downlink access point
Compare high, therefore, the information of downlink access point is forwarded to by multi-upstream access point cannot be considered real-time, such downlink access
Point just needs to do certain delay process in the information forwarded using multi-upstream access point.
This method flow specifically includes：
B1031, the downlink access point are demodulated the descending channel information in t moment, obtain the first downlink letter
Road control signaling, and receive the second downlink channel control signaling that the multi-upstream access point is sent, the second down channel control
Signaling processed is demodulated to obtain in t- time Δts by the multi-upstream access point to the descending channel information.
Wherein, at the time of t moment is demodulated the descending channel information for the downlink access point, Δ t is by institute
State and described user equipment feedback information the time it takes is transmitted between multi-upstream access point and the downlink access point.
Due to multi-upstream access point receive user equipment feedback information be it is real-time, its demodulation result can more subject to
Really, at this time, it is possible to allow the demodulation result that multi-upstream access point is made with regard to itself to be sent to downlink access point for downlink access point
Referred to, but the transmission delay between multi-upstream access point and downlink access point, downlink access point is so resulted in t moment
The demodulating information sent by multi-upstream access point received is really demodulation result of the multi-upstream access point in t- time Δts, therefore
This embodiment of the invention will be come to downlink access point in t with reference to the demodulation difference between t- time Δt uplink and downlink access points
The demodulation result at moment is adjusted.

The 3rd obtained downlink channel control signaling is demodulated, first downlink channel control signaling is adjusted, and according to adjustment
The first downlink channel control signaling afterwards carries out descending scheduling to the user input equipment.
The principle of the adjustment is exactly that the second downlink channel control signaling and the downlink access using on t- time Δts
Difference between point the 3rd downlink channel control signaling of storage, i.e., the correct demodulation completed in multi-upstream access point in t- time Δts
As a result the difference with downlink access point between the actual demodulation result that t- time Δts are completed, to downlink access point in t moment
The first downlink channel control signaling made is calibrated, to ensure that the first downlink channel control signaling more convergence after adjusting is accurate
True channel control signaling.
And multi-upstream access point is completed in the correct demodulation result that t- time Δts are completed with downlink access point in t- time Δts
Actual demodulation result between difference can be embodied in the difference of channel quality information, difference of scheduling resource etc..
Both the above method provides different realization sides between base station or access point for step 103 under different delay
Method, existing communication issue when having taken into full account networking deployment, can effectively provide uplink and downlink business separated management precision.

Speed is higher than under conditions of predetermined threshold value, specifically includes：
A2021, multi-upstream access point generate uplink scheduling information according to the user equipment feedback information.
A2022, multi-upstream access point send the uplink scheduling information to downlink access point, so that the downlink
Access point distributes uplink transmission resource according to the uplink scheduling information for the user equipment, and by the uplink transmission resource
Inform the user equipment.
Wherein, downlink access point is not intended to be believed according to uplink when distributing uplink transmission resource for the user equipment
The information such as road and upstream control signaling carries out uplink transmission resource, but is dispatched by multi-upstream access point, can be expressed as resource
A, but user directly can not get the resource information from multi-upstream access point, it is therefore desirable to user is informed by downlink access point
Which part resource specifically used resource A is on earth, this part informs that signaling is transmitted in downlink communication, and resource A is specific
The resource B of occupancy is only what downlink access point determined.That is, downlink access point is described according to the uplink scheduling information
User equipment distributes uplink transmission resource, exactly resource A is converted into the process of resource B.The resource allocation flow is suitable for this
All related downlink access points that inventive embodiments subsequently provide are distributed according to the uplink scheduling information for the user equipment
The flow of uplink transmission resource.
This implementation method is that the distribution of scheduling resource is completed by multi-upstream access point, but since multi-upstream access point is set with user
Downlink communication quality between standby is difficult to be guaranteed, and therefore, down channel quality can be forwarded in the case of time delay is preferable
Preferable downlink access point is sent to user equipment, ensures the uplink of user equipment.
Method flow as shown in Figure 6 is applied to the information transmission between the downlink access point and multi-upstream access point
Speed is not higher than under conditions of predetermined threshold value, is specifically included：
B2021, multi-upstream access point connect according to the user equipment feedback information in downlink access point for the uplink
On the uplink channel resources that access point is reserved, uplink transmission resource is distributed for the user equipment.
Wherein, the uplink channel resources that downlink access point is reserved for the multi-upstream access point be adaptable to multi-upstream access point and
Transmission delay between downlink access point and the reserved physical resource set for a long time, its purpose is to ensure multi-upstream access point energy
Enough enough channel resources still are able under the influence of time delay carrys out scheduling user's set.
B2022, multi-upstream access point send the uplink transmission resource to downlink access point, in order to which downlink accesses
The uplink transmission resource is informed the user equipment by point so that the user equipment according to the uplink transmission resource with
And the demodulation case of the downlink data sent to the downlink access point, send upstream data to the multi-upstream access point.
Such a implementation by user equipment using its notice uplink transmission resource when, it is necessary to reference to downlink access point
The downlink data of transmission and corresponding control signaling estimate down channel, so as to correctly demodulate multi-upstream access point notice
Channel resource and control signaling.
