Technical scheme provided in an embodiment of the present invention is introduced below in conjunction with the accompanying drawings.During following introduction, it incite somebody to action this
The technical scheme that inventive embodiments are provided is applied exemplified by the scene shown in Fig. 1, and the application scenarios of certain embodiment of the present invention are not
It is limited to this.
Fig. 2 is referred to, one embodiment of the invention provides a kind of method that resource is distributed for user equipment, and this method can lead to
Cross the device provided in an embodiment of the present invention for distributing the device of resource to perform for user equipment, should being user equipment distribution resource
It for example can be base station.The flow of this method is described as follows：
Step 201：All user equipmenies that base station is covered are entered by the signal quality order from low to high of user equipment
Row sequence.
Step 202：Since all user equipmenies the minimum user equipment of signal quality, add up user equipment pair successively
The resource requirement answered, and the corresponding resource requirement of cumulative user equipment is calculated successively in the resource requirement of all user equipmenies
Shared ratio.
Step 203：If the cumulative corresponding resource requirement of M user equipment institute in the resource requirement of all user equipmenies
The ratio accounted for is less than or equal to preset ratio threshold value, it is determined that the corresponding M user equipment of cumulative resource requirement is used for edge
Family equipment, wherein M are positive integer.
Step 204：For edge customer equipment allocations of edge band resource.
In the embodiment of the present invention, although only showing a base station in Fig. 2, but it should being appreciated that, the base station can be same
One or more base station in frequency networking；And exemplified by Fig. 2 being one of user equipment in the base station range,
The user equipment can be one of them in above-mentioned M user equipment or the other users in addition to M user equipment
One of them in equipment.
Base station in the embodiment of the present invention can be any one base station shown in Fig. 1, and user equipment can also be Fig. 1
In any one user equipment.Certainly, in Fig. 1 the quantity of base station and position etc. be only used for signal, in actual applications for
The quantity of the base station of identical networking and position are not limited.Likewise, the quantity of user equipment and position etc. is also only in Fig. 1
For illustrating, quantity in actual applications for user equipment and position etc. are not also limited.
By being used by user equipment and the user equipment of adjacent cell in serving cell in ICIC
Edge band resource difference suppress the interference of identical networking generation, therefore in embodiments of the present invention, in order to suppress with frequency
The interference that networking is produced, it is also desirable to be preferably the user equipment allocations of edge band resource farthest from base station.Therefore, base station is first
All user equipmenies in the base station range can be ranked up according to signal quality descending order.Wherein,
Signal quality can reflect the distance of the distance of user equipment and base station.Signal quality can be by for instruction user equipment
The parameter of communication quality determine, these parameters such as RSRP including user equipment, or the letter of user equipment can be included
Road quality indicates (Channel Quality Indicator, CQI), can either include the SINR of user equipment or may be used also
With the Block Error Rate (Block Error Ratio, BLER) including user equipment, it is, of course, also possible to including other possible parameters,
The embodiment of the present invention is without limitation.Wherein, if signal quality determines that base station can by the RSRP or CQI of user equipment
To require user equipment to report RSRP or CQI, such as user equipment can by dedicated signaling by RSRP or CQI be sent to base
Stand, or RSRP or CQI can also be sent in the lump when sending other information to base station, such as RSRP can follow measurement report
(Measurement Report, MR) is reported together, and CQI can pass through Physical Uplink Control Channel (Physical Uplink
Control Channel, PUCCH) report.If signal quality is determined by the SINR or BLER of user equipment, base station can be with
SINR or BLER is determined according to the data sent in the communication process before user equipment.
The user equipment for example included for Fig. 1, if base station is according to the order descending RSRP of user equipment
To be ranked up, then the order after the user equipment sequence in Fig. 1 is：The ＜ of 6 ＜ user equipmenies of user equipment, 4 ＜ user equipmenies 3
The ＜ user equipmenies 1 of 5 ＜ user equipmenies of user equipment 2.
After being sorted to all user equipmenies, base station the minimum user of signal quality can be set from all user equipmenies
Standby to start, add up the corresponding resource requirement of user equipment successively, and calculates the corresponding resource requirement of cumulative user equipment successively
The shared ratio in the resource requirement of all user equipmenies.
Specifically, requirement of the different user equipmenies to resource is different.Such as non-guaranteed bit speed in LTE system
Rate (Non-Guaranteed Bit Rate, N-GBR) user equipment, is only required to the requirement of minimum guaranteed rate；And ensure ratio
Special speed (Guaranteed Bit Rate, GBR) user equipment, it has high standard to indexs such as time delay, speed, Block Error Rates,
The resource that the user equipmenies of requirements at the higher level needs is then more, that is to say, that its resource requirement of the user equipment of requirements at the higher level is
Higher.For example, in the cell 0 shown in Fig. 1, the quantity of the resource of the request of 1~user equipment of user equipment 6 successively can be with
It is 25,10,15,20,15,15, then the quantity of the resource to be asked of all user equipmenies is 25+10+15+20+15+15=
100。
In embodiments of the present invention, in order that the use for obtaining resource reaches maximization, its optimal situation is just so that edge
The resource requirement of user equipment ratio shared in the resource requirement of all user equipmenies is with edge band resource in the base station
Shared ratio is identical in the frequency domain resource that can be distributed for user equipment.Therefore, preset ratio threshold value for example could be arranged to
Edge band resource ratio shared in the summation of edge band resource and center frequency-band resource, i.e. edge band resource is at this
Shared ratio in the frequency domain resource that base station can be distributed for user equipment.Because ICIC includes dynamic I CIC and static state ICIC two
The mode of kind, wherein, when ICIC is specially static ICIC modes, preset ratio threshold value can be a fixed value, be, for example,
40%；Or, when ICIC is specially dynamic I CIC modes, because during dynamic I CIC modes, edge band resource is in the base station
Shared ratio is dynamic change in the frequency domain resource that can be distributed for user equipment, then preset ratio threshold value can also be
State change.
In embodiments of the present invention, certainly, in actual applications, the ratio shared by general edge band resource is all without too
Greatly, so needing edge customer equipment too many, otherwise edge band resource can be caused more nervous.And can be optimal
The possibility of situation is very little, it is therefore desirable to so that the resource requirement of edge customer equipment is needed in the resource of all user equipmenies
Shared ratio is closer to preset ratio threshold value in asking, and can not be more than preset ratio threshold value.Base station can be from signal matter
The minimum user equipment of amount starts, that is, the user equipment made number one in above-mentioned sequence starts, and adds up successively selected
User equipment requested resource, to calculate the resource requirement ratio of selected user equipment requested resource.If base
Stand and determine that the resource requirement ratio of M cumulative user equipment is less than or equal to preset ratio threshold value, and determine cumulative M+1
The resource requirement ratio of user equipment is more than preset ratio threshold value, then base station can then determine that this M user equipment is used for edge
Family equipment, and determine user equipment centered on the other users equipment in all user equipmenies in addition to this M user equipment.Its
In, M+1 user equipment includes M user equipment and the newly cumulative corresponding user equipment of a resource requirement.
It is to be described in detail by taking the cell 0 shown in Fig. 1 as an example further below.Wherein, according to signal quality from low to high
Ranking results are the ＜ user equipmenies 1 of 5 ＜ user equipmenies of user equipment 6 ＜ user equipmenies, 4 ＜ user equipmenies, 3 ＜ user equipmenies 2, and
And the quantity of the resource of the request of 1~user equipment of user equipment 6 is followed successively by 25,10,15,20,15,15, preset ratio threshold value
For example, 40%.Then base station computational resource requirements ratio, the money of user equipment 6 since the minimum user equipment 6 of signal quality
Source demand is 15, then the resource requirement ratio tried to achieve for the first time is 15/100, and this ratio value is less than 40%.Continue base station
The relatively low user equipment 6 of selection signal quality and user equipment 5 come computational resource requirements ratio, user equipment 6 and user equipment 5
Resource requirement summation be 25+10=35, then the resource requirement ratio tried to achieve for the second time be 35/100, this ratio value again smaller than
40%.Continue selection signal quality relatively low user equipment 6, user equipment 5 and user equipment 3 and carry out computational resource requirements ratio in base station
Example, the resource requirement summation of user equipment 6, user equipment 5 and user equipment 3 is 25+10+15=50, then tries to achieve for the third time
Resource requirement ratio is 50/100, and this ratio value is more than 40%, then base station is corresponding by the preceding resource requirement ratio once tried to achieve
User equipment be defined as edge customer equipment, i.e. the corresponding user equipment of resource requirement ratio 35% will be tried to achieve for the second time true
It is set to edge customer equipment, here, M equipment is the first two user equipment after referring to sort by signal quality, i.e. user sets
Standby 6, user equipment 5.It is corresponding, the other users equipment in addition to edge user equipment in the covering of base station then all centered on use
Family equipment.Wherein, can be identical with above-mentioned cumulative mode when carrying out cumulative, i.e., the resource of a cumulative user equipment is needed every time
Ask；In addition, in actual applications, because the number of user equipment in base station range is a lot, if only increase by one every time
The resource requirement of user equipment is added up, then needs to calculate many times, therefore base station can increase many when often accumulating once
The resource requirement of individual user equipment is added up, such as increased number of user equipment can be 2 or 4 etc., so as to
The time calculated is saved, amount of calculation is reduced.
It is to be understood that, the quantity of resource is asked herein more clearly to illustrate the technology of the embodiment of the present invention
Scheme, thus simplify to the quantity of the resource of request, and in actual applications, on the quantity of request resource may not be
State the quantity enumerated, but it is more increasingly complex than the above-mentioned quantity enumerated many.
In embodiments of the present invention, it is determined that after edge customer equipment, base station can be then these edge customer equipment
Allocations of edge band resource, and centered on user equipment distributing center band resource so that edge customer equipment can pass through
Edge band resource is communicated with base station, and central user equipment can be led to by center frequency-band resource and base station
Letter.For example, the first resource demand percentage that base station is determined is 35%, then base station then can be individual to obtain 35% M for calculating
The user equipment allocations of edge resource of frequency range, that is, it is user equipment 6 and the allocations of edge resource of frequency range of user equipment 5, in addition, base
Stand is also the remaining user equipment distributing center resource of frequency range, that is, be the distributing center frequency range of 1~user equipment of user equipment 4
Resource.
In addition, it is determined that after the attribute of user equipment, that is, determining that user equipment is edge customer in the embodiment of the present invention
It is these edge customer equipment allocations of edge band resources, Yi Jiwei except that can give after equipment or central user equipment
Outside central user equipment distributing center band resource, other scenes can also be applied to, such as according to the category of user equipment
Property it is different, cell also has different modes etc. when switching, and the embodiment of the present invention is without limitation.
In the embodiment of the present invention, to ensure that frequency domain resource is more fully utilized, distributed in base station for edge customer equipment
After edge band resource, base station also can determine whether whether edge band resource also has residue.Specifically, being edge customer in base station
The edge band resource of equipment distribution is met after the resource requirement of edge customer equipment, and base station then can determine whether edge band resource
Whether there is residue, if there is residue, central user equipment can also be given by remaining edge band resource allocation.
In summary, base station can determine money one smaller than preset ratio threshold value according to the resource requirement of user equipment
Source demand percentage, and be defined as being defined as edge customer equipment for calculating certain customers' equipment of the resource requirement ratio.This
Sample, it is possible to make it possible to edge customer equipment ratio shared in all user equipmenies and be in default proportion,
And then can control to be capable of the quantity of edge customer equipment, also would not be as in the prior art only according to the geographical position of user equipment
