Embodiment

Before introducing concrete execution mode, what first illustrate is, judge that the major way that whether can carry out D2D communication between two subscriber equipmenies can comprise: judge that whether the distance between two subscriber equipmenies is enough little, and/or, whether the channel link qualities between two subscriber equipmenies is enough good, if answer is yes, so D2D communication can be carried out between two subscriber equipmenies.

Next it should be noted that, based in the D2D communication of cellular network, the interference of minizone for D2D subscriber equipment to being comparatively serious.When the down-chain resource of D2D subscriber equipment to multiplexing cellular network, D2D subscriber equipment disturbs the cellular subscriber device in transmitting terminal Hui Duizhe community, cellular subscriber device in adjacent cell is disturbed, and serving BS can disturb receiving terminal D2D subscriber equipment.When the uplink resource of D2D subscriber equipment to multiplexing cellular network, D2D subscriber equipment can be subject to the interference of cellular subscriber device in this community to receiving terminal, the interference of cellular subscriber device in adjacent cell, and the interference that D2D subscriber equipment causes serving BS transmitting terminal.In order to the speech quality that available protecting D2D subscriber equipment is right, in the present embodiment, select the ascending resource of multiplexing cellular network.

Again it should be noted that, semi-persistent scheduling (Semi-Persistent Scheduling, referred to as: SPS) be a kind of new scheduling mode introduced in 3GPP.In SPS, the resource (comprising uplink and downlink) of system only need by Physical Downlink Control Channel (Physical Downlink Control Channel, referred to as: PDCCH) distribute or specify once, then just can periodically reuse identical running time-frequency resource.Specifically, at Long Term Evolution (Long Term Evolution, referred to as: LTE) in system, base station can be subscriber equipment (User Equipment, referred to as: UE) distribute certain SPS relevant parameter, the such as SPS cycle, minimum is 10 subframes, is 640 subframes to the maximum, wherein also comprises 32, the semi-static scheduling cycle of the multiple of 64,128 etc. non-10; Such as implicit expression releases order (implicitReleaseAfter), this instruction definition number of times m, if UE does not receive the instruction stopping SPS operation, but it has carried out the transmission that m time does not comprise any data continuously, then UE can discharge SPS resource automatically, stops the transmission of SPS data; Such as SPS downlink interval (semiPersistSchedIntervalDL), like this, UE just can calculate concrete SPS dispatcher meeting based on certain rule.

Here example is spaced apart with SPS downlink, the computational methods of illustratively SPS dispatcher meeting:

(10*SFN+subframe)=[(10*SFNstart?time+subframestart?time)+N*semiPersistSchedIntervalDL]modulo10240

Wherein, SFN is System Frame Number (System Frame Number), subframe is subframe, SFNstart time and subframestart time is SPS corresponding System Frame Number and subframe numbers when starting initialization respectively, semiPersistSchedIntervalDL is SPS downlink interval, and Modulo is modular arithmetic, represents complementation, as 5modulo2=1,7modulo4=3.N is counter, namely a number, and after PS activates, UE can calculate according to above formula and N=1 the subframe (namely base station can be the subframe of UE configuration SPS resource) that first is distributed SPS, or is called SPS point.Then, all possible SPS point below just based on getting N=2,3 ... calculate successively.

And embodiment provided by the invention just by the above-mentioned SPS resource of multiplexing cell cellular subscriber equipment carry out D2D subscriber equipment between communication.

Fig. 1 is the flow chart of an embodiment of the system of selection of equipment direct user equipment Radio Resource provided by the invention, and as shown in Figure 1, the method for the present embodiment comprises:

The equipment that step 101, serving BS are defined as this community in the cellular subscriber device of this community leads directly to D2D subscriber equipment to the candidate cells subscriber equipment providing reusable Radio Resource;

Concrete, serving BS is by global positioning system (Global Position System, referred to as: GPS) obtain the positional information that cellular subscriber device and D2D subscriber equipment in this community are right, according to obtain this cell cellular of positional information calculation subscriber equipment to D2D subscriber equipment between distance, chosen distance is more than or equal to the cellular subscriber device alternatively cellular subscriber device of predeterminable range.

Wherein, as shown in Figure 2, suppose that the radius of society that serving BS covers is R, serving BS is positioned at the center of community, the all cellular subscriber device being positioned at this community are evenly distributed on community, and D2D subscriber equipment is positioned at cell edge to UE1 and UE2, and close together.UE3 is cellular subscriber device.Because the right distance of D2D subscriber equipment is much smaller than serving BS to the distance of UE1, therefore, D2D subscriber equipment is negligible to the interference of transmitting terminal to serving BS.If the polar coordinates of UE1 are (r _d, 0), the polar coordinates of UE3 are (r _c, θ), the distance calculating cellular subscriber device UE3 to UE1 can be, but not limited in the following way:

L = \sqrt{r_{C}^{2} + r_{D}^{2} - {2 r}_{C} r_{D} \cos θ}

Predeterminable range Lm can set according to such as under type, but is not limited to following this mode.Suppose that the maximum interference power that D2D user's proper communication can bear is Pa, the transmitting power mean value of cellular subscriber device is Pb, then predeterminable range Lm should meet Pa=Pb/d ⁴.Cellular subscriber device is from D2D subscriber equipment to away from more, and the interference power that D2D user receives is less.

Step 103, the semi-persistent scheduling SPS resource alternatively SPS resource that candidate cells subscriber equipment is used, the information of candidate SPS resource is sent to adjacent base station, in the community of adjacent base station coverage, determines the target cell subscriber equipment of use candidate SPS resource to make adjacent base station according to the information of candidate SPS resource.

Wherein, the information of candidate SPS resource can be sent to adjacent base station by X2 interface by serving BS.
