Transmittability, therefore the method that the embodiment of the present invention proposes scheduling user's set below, lower mask body combination Fig. 1-Fig. 4 are carried out
Explanation.
Fig. 1 is please referred to, is the flow diagram of the first embodiment of the method for scheduling user's set of the present invention, in this implementation
In example, it the described method comprises the following steps:
S101, base station determine processing delay.
Wherein, the processing delay receives the channel quality indicator (CQI) of reported by user equipment UE to institute for the base station
Base station is stated to start to dispatch the time delay of UE.
S102, chooses preset CQI historical data under current open state and calculates history and be averaged CQI.
Optionally, the corresponding CQI historical data of TTI before the preset CQI historical data refers to current TTI,
When actually choosing, the CQI historical data of previous TTI can be only chosen, is then counted with the current TTI CQI received
Calculation obtains the corresponding history of current TTI and is averaged CQI；Or the corresponding CQI of multiple TTI before also can choose current TTI is gone through
History data carry out summation and are averaged；Or it can also be to the corresponding CQI historical data of multiple TTI selected before current TTI
It is weighted summation；Or it is also an option that the corresponding CQI historical data of multiple TTI and current TTI before current TTI connect
The CQI received, which is weighted summation and obtains the corresponding history of current TTI, to be averaged CQI；The embodiment of the present invention is not limited in any way.
Certainly, it should be noted that since the historical data reliability and accuracy closer to current TTI are higher,
It can pay the utmost attention to, and for can handle the TTI except time delay, can receive more accurately CQI, therefore calculating
When current CQI, can set a time window for determine calculate history be averaged CQI TTI weight, especially to close base

Quantity may also be different).Then base station enters current open state after 6ms, falls the 8th TTI from the 1st TTI and is in out
State is opened, switchs to closed state from the 9th TTI, closed state continues to the 14th TTI；If base station is in close state, often
Whether a TTI detection once meets the condition of base station switch strategy, once meeting condition, just opens base station.If base station from
15th TTI is again introduced into open state, then since the 15th TTI, is continued for duration corresponding with the processing delay
Such as 6 TTI, that is, continue to the 20th TTI, UE is dispatched using the history CQI that be averaged, without due in processing delay
It does not receive CQI and is dispatched without UE.
In the TTI after the 20th TTI, since base station can receive the accurate CQI that UE is reported, from
21 TTI start, and the CQI scheduling UE that base station receives, the i.e. processing after the base station is opened next time can be used
Except the duration of time delay, UE is dispatched according to the CQI of UE real-time report.Certainly, it can continue to usage history at this time to be averaged CQI tune
Degree, the embodiment of the present invention are not limited in any way.
In the present embodiment, by determining processing delay, and preset CQI historical data meter under current open state is chosen
History is calculated to be averaged CQI, in this way, be in the corresponding duration of processing delay when base station is opened next time, it can usage history
Average CQI dispatches UE, history be averaged CQI accuracy it is higher, can more fully reflect the quality of channel, therefore avoid
Base station does not use the case where dispatch channel resource UE in processing delay, can greatly promote the overall transfer efficiency of channel, together
When lifting system handling capacity and reduce error rate of system.
It should be noted that the frequency of base station switch can be different according to different switching strategies.Switching frequency is higher
When, method described in the embodiment of the present invention is more obvious to the gain effect of power system capacity.Firstly because on-off times are more,
Time of the channel that CQI_avg is quantified apart from present channel is closer, i.e., the closer historical data the more reliable apart from current time,
CQI_avg gets over the status information that can reflect present channel, has to error rate of system reduction and the promotion of handling capacity apparent
Effect.

S202, chooses preset CQI historical data under current open state and calculates history and be averaged CQI.
S203 records current transmission time interval TTI to the base station if base station switchs to open state by closed state
The gap length of current open state starting point.
S204, judges whether the gap length is less than or equal to the processing delay.If so, S205 is thened follow the steps,
It is no to then follow the steps S206.
S205, using the history be averaged CQI scheduling UE.
S206 dispatches UE according to the CQI of UE real-time report.
While executing step S206 or later, history can also be calculated and be averaged CQI so as to when base station is opened next time
It uses.Specifically it can comprise the following steps that
If the gap length is greater than the processing delay, the difference of the gap length Yu the processing delay is calculated
Value；
Judge whether the difference is less than the length of preset time window, the length of the preset time window is for determining
