Abstract
The invention discloses an optimization method for resource pool size adjustment based on a D2D terminal feedback value, and belongs to the technical field of resource pool adjustment. The optimization method comprises the steps that: a base station firstly presets upper and lower threshold values of resource use for an allocated resource pool, and informs terminals supporting a D2D function of the upper and lower threshold values in a form such as broadcasting; the D2D terminal while selecting resources in the resource pool obtains state information of the current resource pool periodically or in an event-triggered passive mode and compares the obtained state value of the resource pool with the threshold values preset by the base station; and the base station adjusts the size of the resource pool based on feedback information from the terminal. The optimization method for resource pool size adjustment based on the D2D terminal feedback value can avoid the resource waste phenomenon and can adjust the size of the resource pool flexibly.
Description
Technical field
The invention belongs to resource pool adjustment technology field in communication 5G, be specifically related to a kind of optimization method based on D2D terminal feedback value adjustresources pond size.
Background technology
D2D communication refers to: the communication between two users without base station, can directly carry out end-to-end direct-connected communication.Because its communication distance limits to some extent, so low-power consumption information can be sent, to reduce the energy ezpenditure of terminal.D2D communication is expected to one of effectively supplementary technology becoming future communications.Simultaneously, for the resource acquisition mode of D2D communication, no matter be that signaling sends or data send, the agreement that current R-12 version draws is: resource acquisition mode, namely traditional base station scheduling Resources allocation mode and the Stochastic choice mode of resource pool of supporting two kinds of modes.For the transfer of data in D2D communication, respectively define two kinds of mode: mode1 and mode2.Mode2 is the mode of base station random division resource pool.Namely, under this mode, D2D terminal is communicated by Gains resources random in resource pool.
But, for resource pool size issue, the suggestion that current each company reaches is, allows the conversion (i.e. resource acquisition mode can be transformed into mode1 by mode2) of resource acquisition mode; When resource pool is not enough, base station, by receiving the related feedback information from D2D terminal, increases resource pool.But, but do not consider the situation reducing resource pool.To there will be the wasting of resources even degradation problem under Consumer's Experience like this.Based on this, the present invention proposes a kind of scheme of flexible dynamic conditioning resource pool, and the program can preferably according to the feedback information of D2D terminal, adjustresources pond size, to avoid wasting of resources phenomenon.
Summary of the invention
For following existing deficiency, propose a kind of optimization method based on D2D terminal feedback value adjustresources pond size avoiding wasting of resources phenomenon, flexibly adjustresources pond size.。Technical scheme of the present invention is as follows: a kind of optimization method based on D2D terminal feedback value adjustresources pond size, and it comprises the following steps:
101, base station provides resource pool for D2D terminal, meanwhile, and the upper and lower limit threshold value N that presetting resource is used
up_thresholdand N
down_thresholdinform to the D2D terminal in community;
102, D2D terminal is while Gains resources Pooled resources, and the passive mode that periodicity or event trigger obtains the state value in Current resource pond;
103, the presetting threshold value of this state value and base station contrasts by D2D terminal respectively, and the indication information I of resource pool situation of feedback for feeding back
upand I
down; Wherein I
up: represent that the D2D terminal as recipient detects that state value is more than or equal to N
up_threshold, namely feed back I
up.; I
down, when the D2D terminal of recipient detects that state value is less than N
down_threshold, namely feed back I
down;
104, in base station in the Measuring Time cycle of D2D terminal profile, base station is collected from the I of D2D terminal feedback multiple in coverage
upand I
downafterwards, by I
upand I
downnumber of times contrast, when feedback I
upnumber of times is greater than I
downduring number of times, increase the size of resource pool; Otherwise, reduce resource pool or maintenance.
Further, after step 104 adjusts described resource pool, when the adjustment result of described resource pool is: when reducing or keep described resource pool size, and for the I of feedback
upnumber of times is greater than I
downthe D2D terminal of Times of Feedback, described base station communicates for described D2D terminal divides resource pool separately, becomes mode2 by mode1.
Further, behind step 104 adjustresources pond, when resource pool is sufficient, part resource in the described resource pool of the selectable withdrawal in base station or the resource do not regained in described resource pool, and all terminals under the resource pool information broadcasting after the described adjustment after adjustment being covered to it by the forms of broadcasting, the terminal of other non-D2D communication can use this resource pool, and for the terminal of " sleep " in coverage, terminal is told by paging way in described base station.
Further, base station described in step 101 provides described resource pool for the mode of described D2D terminal for providing one piece of resource pool at random, and the upper and lower threshold value that presetting resource uses is informed and to be comprised to the mode of terminal in community under described base station: A, the terminal use described threshold value told by the mode broadcasted in described base station range; B, terminal are connected by setting up RRC with described base station, obtain threshold information.
Further, presetting described threshold value N
up_thresholdand N
down_threshold, be selected from following one or combination: (1), activation D2D number of terminals upper and lower limit threshold value; (2), the service efficiency upper and lower limit threshold value of resource pool.
Further, the state value in described step 102 comprises: (1), the D2D number of users activated; (2), resource utilization.
Advantage of the present invention and beneficial effect as follows:
The present invention mainly when Random assignment resource pool, base station according to the D2D terminal in its coverage to its feedback information, according to the size of threshold value dynamic conditioning resource pool preset.This adjustment mode also comprises except increasing resource pool the size reducing resource pool.Meanwhile, for special D2D terminal, adopt the mode of Resourse Distribute conversion.Take into account the situation reducing resource pool.There will not be the wasting of resources even problem of Consumer's Experience decline like this.

Fig. 2 is schematic diagram when reducing or maintain resource pool.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention is main it is considered that cover scene that is interior and Random assignment resource pool.For D2D communication, current 3GPP on the basis of terminal scheduling resource, proposes a kind of new resource distribution mode in traditional LTE base station, i.e. random division one piece of resource pool, namely one piece of RB Resource Block.All can see in LTE after R12 version.Wherein,
N
