Fig. 1 is the schematic diagram of an example of the scene that can apply the embodiment of the present invention.It should be noted that Fig. 1 example be for Help those skilled in the art more fully understand the embodiment of the present invention, the scope of the embodiment that is not intended to limit the present invention.

In fig. 1, it is assumed that base station 110 covers 3 sectors 130a, 130b and 130c in some carrier wave.Base station 110 is served 8 UE, 8 UE are located at 3 sectors respectively.For example, UE 120a, UE 120b and UE 120c are located at sector 130a.UE 120d It is located at sector 130b with UE 120e.UE 120f, UE 120g and UE 120h are located at sector 130c.

In 8 UE, D2D communications can be carried out between the UE with D2D abilities.For example, it is assumed that UE 120a, UE 120b and UE 120c are respectively provided with D2D communication capacities, then UE 120a and UE 120b can carry out D2D communications, and UE 120a can also be with UE 120c carry out D2D communications, and UE 120b can also carry out D2D communications with UE 120c.So, the UE with D2D communication capacities Between can by D2D communication carry out data transmission, need not move through base station forwarding.

It should be noted that 3 sectors of the base station on some carrier wave are only described for convenience of description, in Fig. 1, but the present invention Embodiment is not limited to this, and base station can also possess the sector on other carrier waves.In addition, the number for the UE that base station is serviced is also Can be less or more, the embodiment of the present invention is also not construed as limiting to this.

Fig. 2 is the indicative flowchart of D2D communication means according to embodiments of the present invention.Fig. 2 method is performed by UE.

210, the first UE are from base station received spectrum occupied information, and the Spectrum Occupancy Information is used to indicate at least one subregion institute The uplink frequency spectrum resource of occupancy, at least one subregion is that the cell covered to the base station carries out dividing what is obtained.

The first uplink spectrum is selected in the uplink frequency spectrum resource set that 220, the first UE can be used in D2D communications from the first UE Resource, and D2D communications are carried out using the first uplink frequency spectrum resource and the 2nd UE, wherein uplink frequency spectrum resource set is the first UE roots Determined according to Spectrum Occupancy Information.

First UE and the 2nd UE can use uplink frequency spectrum resource to carry out D2D communications, because uplink frequency spectrum resource is to be used for UE is to the uplink communication of base station, and the antijamming capability of base station is better than UE, therefore carries out D2D communications using uplink frequency spectrum resource, The interference to the communication in existing network between UE and base station can be reduced.

Alternatively, as one embodiment, in step 210, Spectrum Occupancy Information can serve to indicate that whole subregion institutes The uplink frequency spectrum resource of occupancy, or Spectrum Occupancy Information can serve to indicate that the uplink spectrum shared by the subregion of the first UE places Uplink frequency spectrum resource shared by resource and/or the 2nd UE places subregion, or the Spectrum Occupancy Information can serve to indicate that Uplink spectrum money shared by other subregions in whole subregions in addition to subregion where subregion where the first UE and/or the 2nd UE Source.

Describe the form of the Spectrum Occupancy Information of the embodiment of the present invention in detail below in conjunction with specific example.It should be noted that under Face Fig. 7 to Fig. 9 example is to aid in those skilled in the art and more fully understands the embodiment of the present invention, is not intended to limit the present invention The scope of embodiment.

Fig. 7 is an example of the form of the Spectrum Occupancy Information of the example for being applicable to Fig. 6 according to embodiments of the present invention The schematic diagram of son.As shown in fig. 7, in Spectrum Occupancy Information, every 3 bit corresponds to an allocation unit, these allocation units with The order of allocation unit in Fig. 6 is consistent.For example, in the figure 7, first 3 bit " 101 " can represent the 1st distribution Unit belongs to the 5th subregion；Second 3 bit " 011 " can represent that the 2nd allocation unit belongs to the 3rd subregion；3rd 3 bits " 100 " can represent that the 3rd allocation unit belongs to the 4th subregion.The like.

As shown in figure 8, in Spectrum Occupancy Information, one subregion of every 6 bit correspondence.Corresponding 6 subregions of spectrum information are Arrange in sequence, that is, with the order of the subregion in Fig. 5 be consistent.Predefined list or predefined can be passed through Calculation, obtain every 6 bit and indicate allocation unit shared by corresponding subregion.For example, in fig. 8, can be by pre- The list of definition learns that first 6 bit " 000110 " can represent that the allocation unit shared by the 1st subregion is reciprocal 4th Allocation unit；Second 6 bit " 000000 " can represent that the 2nd subregion does not take allocation unit；3rd 6 bits " 000011 " can represent that the allocation unit shared by the 3rd subregion is the 2nd allocation unit.The like.It should be noted that above-mentioned number The citing of value is intended merely to help those skilled in the art to more fully understand the embodiment of the present invention, and be not intended to limit the present invention embodiment Scope.

Fig. 9 is another example of the form of the Spectrum Occupancy Information of the example for being applicable to Fig. 6 according to embodiments of the present invention The schematic diagram of son.As shown in figure 9, in Spectrum Occupancy Information, each bit corresponds to an allocation unit.Whole bits are corresponding The order of the order of whole allocation units and the allocation unit in Fig. 6 is consistent.Assuming that when bit is " 0 ", representing the bit Corresponding allocation unit is not shared by the 1st subregion where UE 120a and UE120b.When bit is " 1 ", the bit pair is represented The allocation unit answered is shared by the 1st subregion.

403, the Spectrum Occupancy Information that base station 110 is determined into UE120a forwarding steps 402.

Alternatively, base station 110 can send Spectrum Occupancy Information to one group of UE, wherein, one group of UE at least includes UE120a, Or one group of UE at least includes whole UE in the subregion of UE 120a places.

Base station 110 can send Spectrum Occupancy Information to one group of UE including the first UE, wherein, one group of UE can be UE Whole UE in the 1st subregion where 120a, or one group of UE can be the whole in the multiple adjacent sectors for include the 1st subregion UE, either one group of UE can be that whole UE or one group of UE of whole subregions can be to have D2D abilities in the 1st subregion UE, either one group of UE can be that UE or one group of UE with D2D abilities in the multiple adjacent sectors for include the 1st subregion can Think the UE with D2D abilities of whole subregions, or one group of UE can be in the angle where the UE 120a of wave beam alignment Whole UE, or one group of UE can be the UE with D2D abilities in the angle where the UE 120a of wave beam alignment.

Specifically, base station 110 can send Spectrum Occupancy Information to whole UE of the 1st subregion, can also be to including the 1st point Whole UE of multiple adjacent sectors in area send Spectrum Occupancy Information, can also send frequency spectrum to whole UE of whole subregions and take Information.Base station 110 can also send Spectrum Occupancy Information to the UE with D2D abilities of the 1st subregion, can also be to including the 1st The UE with D2D abilities of multiple adjacent sectors of subregion sends Spectrum Occupancy Information, can also have D2D to whole subregions The UE of ability sends Spectrum Occupancy Information.The embodiment of the present invention is not construed as limiting to this.If base station 110 support smart antenna array or Whole UE of angle where the orientating functions such as 3D BF, then base station 110 can be aligned to wave beam UE120a or with D2D communications The UE of ability sends Spectrum Occupancy Information.

Alternatively, base station 110 can be in any subframe of the N subframes into (N+k-1) subframe to UE 120a transmissions Spectrum Occupancy Information for indicating the uplink frequency spectrum resource in (N+k) subframe shared by least one subregion, wherein N and k For positive integer.
