Below in conjunction with Figure of description, embodiments of the invention are described, should be appreciated that embodiment described herein is only for instruction and explanation of the present invention, is not limited to the present invention.And when not conflicting, the embodiment in this explanation and the feature of embodiment can be combined with each other.
The embodiment of the present invention provides a kind of dispatching method of user terminal, is illustrated in figure 1 the realization flow figure of the method, mainly comprises the steps:
Step 11, from carrying out in the user terminal dispatched at same running time-frequency resource, determines to make to utilize energy efficiency values during running time-frequency resource transmission downlink data to be greater than the user terminal to be scheduled of the power efficiency threshold pre-set;
Wherein, the user terminal to be scheduled determined should meet: what send transmission power value needed for downlink data respectively to each user terminal to be scheduled is not more than the maximum transmit power value of base station with value.
Optionally, this step can specifically comprise:
First according to existing scheduling mode from carrying out in the user terminal dispatched at same running time-frequency resource, determine first user terminal.Such as according to the mode determination first user terminal of poll; Or proportionally fair (Proportional Fairness, PF) algorithm, can be defined as first user terminal by the user terminal possessing largest pf value carried out in the user terminal dispatched on same running time-frequency resource; Or the user terminal possessing maximum signal to noise ratio (Max Signal to Ineterferenceplus Noise Ratio, Max SINR) that can carry out on same running time-frequency resource in the user terminal dispatched is defined as first user terminal.
Then judge whether the parameter value of the channel quality characterizing this first user terminal is less than the threshold value pre-set, wherein, the parameter value characterizing the channel quality of this first user terminal can be the signal to noise ratio of this user terminal;
When the parameter value of the channel quality judging this first user terminal is greater than the threshold value pre-set, illustrate that the channel quality of this first user terminal is relatively better, namely signal strength signal intensity is comparatively large, and noise intensity is less.If be only this first user terminal to send downlink data on above-mentioned running time-frequency resource, the data volume so transmitted on this running time-frequency resource and its actual data volume that can transmit should be more or less the same, and therefore only this first user terminal can be defined as user terminal to be scheduled.
When the parameter value of the channel quality judging this first user terminal is less than the threshold value pre-set, illustrate that the channel quality of this first user terminal is relatively poor, namely signal strength signal intensity is less, and noise intensity is larger.If be only this first user terminal to send downlink data on above-mentioned running time-frequency resource, the data volume so transmitted on this running time-frequency resource is certain to much smaller than its actual data volume that can transmit, therefore while first user terminal is defined as user terminal to be scheduled, also need from other user terminals except this first user terminal, determine to make to utilize energy efficiency values during running time-frequency resource transmission downlink data to be greater than other user terminals to be scheduled of the power efficiency threshold pre-set.
Wherein, in order to make on same running time-frequency resource simultaneously for the energy efficiency values when user terminal to be scheduled determined sends downlink data can reach optimum, namely the data volume utilizing this running time-frequency resource to transmit can reach maximum, when determining other user terminals to be scheduled, except making to utilize energy efficiency values during running time-frequency resource transmission downlink data to be greater than the power efficiency threshold pre-set, also need to make this energy efficiency values reach maximum.
In addition, the power efficiency threshold pre-set according to actual conditions by user's sets itself, can not do concrete restriction to it at this.
Wherein, in a wireless communication system, so-called energy efficiency, refer to the bit number that unit energy can transmit, unit is bit/joule.
Step 12, utilizes running time-frequency resource to send downlink data to the user terminal to be scheduled determined.
In this step, should using send transmission power value needed for downlink data respectively to user terminal to be scheduled described in each with value as transmission power value when sending downlink data, utilize running time-frequency resource to send downlink data to the user terminal to be scheduled determined.
The embodiment of the present invention is passed through from carrying out in the user terminal dispatched at same running time-frequency resource, determine to make to utilize energy efficiency values during running time-frequency resource transmission downlink data to be greater than the user terminal to be scheduled of the power efficiency threshold pre-set, then utilize this running time-frequency resource to be that the user terminal to be scheduled determined sends downlink data.Due to when determining until scheduling user terminal, with this factor of energy efficiency values for selection gist, to make on same running time-frequency resource simultaneously for the energy efficiency values when user terminal to be scheduled determined sends downlink data can reach the comparatively figure of merit, be greater than in prior art the data volume utilizing this running time-frequency resource to transmit, thus the utilance that improve running time-frequency resource, avoid exist in prior art may cause the problem that the utilance of running time-frequency resource is lower.
Based on above-mentioned principle, the embodiment of the present invention additionally provides said method a kind of embody rule flow process in practice, and as shown in Figure 2, the method mainly comprises the following steps:
Step 21, from carrying out, in the user terminal dispatched, determining first user terminal at same running time-frequency resource, this first user terminal is the user terminal possessing the fair PF value of maximum ratio that can carry out on same running time-frequency resource in the user terminal dispatched;
Wherein, PF value can be determined according to following formula:
PF＝R/T （1）
Wherein, R is the data rate that the subscriber channel of user terminal can be supported, T is the transmission data that subscriber channel is total in predetermined time period.

Step 25, according to the spectrum efficiency of each user terminal determined, determines the common corresponding energy efficiency values of the spectrum efficiency of other each user terminals of the spectrum efficiency of user terminal to be scheduled respectively and except user terminal to be scheduled respectively;
Wherein, when only determining a user terminal to be scheduled and first user terminal, the common corresponding energy efficiency values of spectrum efficiency of each user terminal of the spectrum efficiency of first user terminal respectively and except first user terminal can be determined according to following formula:
η Ei = ( SE 1 + SE i ) η PA | h 1 | 2 ( ( 2 S E 1 - 1 ) + k ( 2 S E 1 - 1 ) + ( 2 S E i - 1 ) + ( 2 S E i - 1 ) ) N 0 + P static - - - ( 2 )
Above-mentioned formula (2) is determined according to formula (3) and formula (4):
P 1 + P i = WN 0 η PA | h 1 | 2 ( 2 S E 1 - 1 ) + k ( 2 S E 1 - 1 ) ( 2 SEi - 1 ) + ( 2 SEi - 1 ) - - - ( 3 )
k = | h 1 | 2 | h i | 2 - - - ( 4 )

Step 29, determines to the transmission power value needed for user terminal transmission downlink data to be scheduled respectively, and sends the transmission power value needed for downlink data to the described user terminal selected;
Wherein, when determining transmission power value, can be, but not limited to adopt following two kinds of modes:
First kind of way:
First, according to the spectrum efficiency of the user terminal selected, the user terminal of true M8003 line sends the transmission power value needed for downlink data; Then,
According to spectrum efficiency and the transmission power value required when sending downlink data to the user terminal selected of user terminal to be scheduled, determine to the transmission power value needed for user terminal transmission downlink data to be scheduled.
Wherein, be except first of the first user terminal the determined user terminal selected is specifically described for the user terminal selected below.The user terminal of this selection is referred to as user terminal 2, and its spectrum efficiency is SE 2, be P to user terminal 2 transmission power value sent needed for downlink data 2, so P 2can determine according to following formula:
SE 2 = log ( 1 + η PA P 2 | h 2 | 2 WN 0 ) - - - ( 5 )
Then, determine to the transmission power value P needed for first user terminal transmission downlink data according to following formula 1:
SE 1 = log ( 1 + η PA P 1 | h 1 | 2 WN 0 + η PA | h 1 | 2 P 2 ) - - - ( 6 )
The second way:
First, the Modulation and Coding Scheme of the Modulation and Coding Scheme of user terminal to be scheduled and the user terminal of selection is determined respectively;
Then, according to the Modulation and Coding Scheme of the Modulation and Coding Scheme of user terminal to be scheduled determined and the user terminal of selection, and the interfere information between user terminal to be scheduled and the user terminal of selection, determine to the transmission power value needed for user terminal transmission downlink data to be scheduled, and send the transmission power value needed for downlink data to the described user terminal selected.
