Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the present invention clearer, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
The schematic flow sheet of the resource allocation methods that Fig. 1 provides for one embodiment of the invention, as shown in Figure 1, the resource allocation methods of the present embodiment can comprise the following steps:
Wherein, above-mentioned channel quality parameter can indicate for channel quality (Channel Quality Indicator is called for short CQI), signal noise ratio (Signal to Noise Ratio is called for short SNR) etc. can reflect the parameter of channel quality.
In this step, can be by base station equipment, for example: the evolved base station in long evolving system, according to the dispatching sequence, determine the current terminal be scheduled.Particularly, can determine according to the dispatching priority indication and also can determine the dispatching sequence of terminal in community with reference to other modes of the prior art and the dispatching sequence of terminal in community repeat no more herein.
If the above-mentioned channel quality parameter of step 102 is more than or equal to the parameter threshold set in advance, it is the community interface-free resources of above-mentioned terminal distribution part.
Particularly, when in community, the channel quality parameter of the current terminal be scheduled is more than or equal to the parameter threshold set in advance, can, by base station equipment according to the resource threshold set in advance, be the above-mentioned terminal distribution community interface-free resources corresponding with above-mentioned resource threshold.Herein, the resource threshold set in advance is to distribute to the interface-free resources of terminal and the proportion threshold value of current available cell interface-free resources, and this resource threshold is less than 100%.For example: this resource threshold is 70%, for the terminal distribution community interface-free resources corresponding with above-mentioned resource threshold, that is to say, is 70% of the current available cell interface-free resources of above-mentioned terminal distribution.
It should be noted that: above-mentioned resource threshold can be arranged according to actual needs, for example: can be for according to being added up or empirical value that emulation obtains under a certain scene, the empirical value under different scenes may be different; Perhaps above-mentioned resource threshold can be also a median, for example: 50%.Further, for the channel quality of the terminal that guarantees current scheduling, also can establish a lower limit to this threshold value, and the value of this lower limit is relevant with actual scene, the embodiment of the present invention is not given an example one by one.
Further, after this step, can further include at least one terminal distribution remaining community interface-free resources of base station equipment for being scheduled after above-mentioned terminal.
Wherein, above-mentioned community interface-free resources can comprise the resources such as power resource and channel code resources.Particularly, if the channel quality parameter of obtaining is CQI, the above-mentioned parameter threshold value can be set to 26; If the channel quality parameter of obtaining is SNR, the above-mentioned parameter threshold value can be set to 21.5dB.Be understandable that, the setting of above parameter threshold is an example, and the parameter threshold of channel quality can and need to be arranged according to different situations.
Particularly, if above-mentioned channel quality parameter is more than or equal to the parameter threshold set in advance, the channel quality that the current terminal be scheduled is described is better, base station equipment can be according to the resource threshold set in advance, be restricted to the community interface-free resources that this current terminal be scheduled is distributed, thereby make this current terminal be scheduled can only obtain a part of community interface-free resources corresponding with above-mentioned resource threshold, and remaining another part community interface-free resources is distributed to at least one terminal be scheduled after above-mentioned terminal.
In the present embodiment, while in the Dang Yige community, having a plurality of terminal, base station equipment is by obtaining the channel quality parameter of the current terminal be scheduled in community, if above-mentioned channel quality parameter is more than or equal to the parameter threshold set in advance, it can be the community interface-free resources of above-mentioned terminal distribution part, specifically, if above-mentioned channel quality parameter is more than or equal to the parameter threshold set in advance, can be according to the resource threshold set in advance, for the current terminal distribution the be scheduled community interface-free resources corresponding with above-mentioned resource threshold, and the remaining community of at least one terminal distribution interface-free resources for being scheduled after above-mentioned terminal, thereby can be on the basis of the fairness differentiation between the user who destroys hardly the scheduler decision, improve allocation efficiency of resource and community throughput.
It should be noted that, the resource allocation methods of the present embodiment, not only go for long evolving system, applicable equally for the other system that has Similar Problems.
The schematic flow sheet of the resource allocation methods that Fig. 2 provides for another embodiment of the present invention, in the present embodiment, take long evolving system as example, and weigh channel quality by CQI.In the present embodiment Zhong， community 1, the dispatching sequence of terminal is followed successively by terminal A, terminal B, terminal C, terminal D, terminal E, terminal F, terminal G, terminal H, and parameter threshold is 26 (CQI), and resource threshold is 70%.As shown in Figure 2, the resource allocation methods of the present embodiment can comprise the following steps:
Step 201, evolved base station, according to the dispatching sequence, determine that the current terminal be scheduled is terminal A;
Step 202, evolved base station are obtained the CQI that terminal A reports;
Step 203, evolved base station judge whether above-mentioned CQI is more than or equal to 26, if so, perform step 204, otherwise, process ends;
Step 204, evolved base station are that terminal A distributes 70%De community interface-free resources;
Step 205, evolved base station are according to the dispatching sequence, and the terminal be scheduled after terminal A under determining is terminal B;
Step 206, evolved base station are that terminal B distributes residue 30%De community interface-free resources.
In the present embodiment, while in the Dang Yige community, having a plurality of terminal, evolved base station is by obtaining the CQI of the current terminal be scheduled, if this CQI is more than or equal to 26, can be according to the resource threshold 70% set in advance, for the current terminal distribution 70%De community interface-free resources be scheduled, and at least one terminal distribution residue 30%De community interface-free resources for being scheduled after above-mentioned terminal, thereby can, on the basis of the fairness differentiation between the user who destroys hardly the scheduler decision, improve allocation efficiency of resource and community throughput.
