Alternative embodiment two

As shown in figure 9, in V2X communications, 3 mode UE of mode and 4 mode UE of mode are shared to send resource pool, and 700 are The transmission resource collection of 3 mode UE of mode, to send the first subset of resource pool, 702 be the transmission resource set of 4 mode UE of mode It closes, to send resource pool second subset, 701 be boundary resource region, including a certain number of radio resources, as shown in fig. 6, Time domain includes one or more adjacent or non-conterminous wireless sub-frames, includes one or more subcarriers, RB or sub- on frequency domain Channel, sub-channel here includes one or more RB.Here it is provided by boundary of a sub-channels sub-channel Source region carries out embodiment explanation.703 be that the UE of 3 modes of mode sends the resource of control and/or data occupancy, and 704 be mode The resource that the UE of 4 modes sends control and/or data occupy.705 and 706 be 1 He of extreme position in boundary resource region respectively Extreme position 2.

The initial position in boundary resource region 701 is configured or is pre-configured by base station or predefined determination, is communicated in V2X In, base station be 3 modes of mode UE in 700 scheduling resource, the UE of 4 modes of mode at 702 according to sensing results from Main selection resource.

When the UE quantity of 3 modes of mode increases or demands of the UE to resource increases, 3 modes of mode finally dispatched UE can use the resource for sending the first subset of resource pool 700, then 3 mode UE of mode are dispatched to boundary resource region by base station In 701；There is resource occupied or in boundary resource region 701 when 4 mode UE of mode are listened in boundary resource region 701 In can detect signal energy, then be judged as that the UE of 3 modes of mode occupies the resource in boundary resource region, while if root It is believed that number monitoring or signal energy detection, judgement have in the range of neighbouring boundary resource region in sending resource pool second subset Idling-resource, and idling-resource is more than the size in the boundary resource region, then exit send in resource second subset 702 with side The closest resource of boundary's resource area 701 reduces the size and range for sending resource pool second subset, the scope of resource exited For the identical or bigger with 701 size of boundary resource region.If the resource that the UE of 3 modes of mode is occupied continues to increase, boundary Continue to move to the inside of transmission resource second subset 702 in the position of resource area.But mobile range is limited no more than base stage 706 are set, determines that the mode of the value of base stage extreme position 706 includes：Base station configures, or is pre-configured, or predefined.

Alternatively, the UE of 4 modes of mode do not judge send resource pool second subset in whether available free resource, if monitor To having resource occupied in boundary resource region 701 or in boundary resource region 701 can detect signal energy, then retract It sends in resource pool second subset with the closest resource in boundary resource region 701, that is, reduces and send resource pool second subset Size and range, the scope of resource exited are identical or bigger with 701 size of boundary resource region.It also corresponds to toward transmission resource The position of 702 inside moving boundary resource area of pond second subset.

On the contrary, when the UE quantity of 3 modes of mode reduces or the radio resource of demand reduces, the first son of resource pool is sent Idling-resource can be vacated in collection 700, when idling-resource quantity reaches the size or bigger in boundary resource region 701, then base It stands through the scheduling to mode 3, the resource neighbouring with boundary resource region 701 is vacated in sending resource collection 700, with side Resource area 701 size in boundary's is identical or bigger.When 4 mode UE of mode listen to send resource collection 700 in boundary resource area When the closest size in domain 701 is identical or the resource of bigger is idle, then original boundary resource region is occupied when selecting resource 701 resource, and provided the resource closest with boundary resource region 701 vacated in set 700 is sent as new boundary Source region.Its result is exactly to send the size and range shorter of the first subset of resource pool 700, sends resource pool second subset 702 size and range becomes larger, boundary resource region 701 toward send the first subset of resource pool 700 inside move.If mode The UE quantity of 3 modes or the radio resource of demand continue to reduce, then send the first subset of resource pool 700 and continue to become smaller, and send money Source pond second subset 702 continues to become larger, and the position in boundary resource region continues to move to the inside of transmission resource collection 700.But it moves Dynamic range determines that the mode of the value of base stage extreme position 705 includes no more than base stage extreme position 705：Base station configuration or prewired It sets, or predefined.

Alternatively, in the present embodiment, the UE things of mode 3, priority scheduling to the first son of the transmission resource pool are dispatched in base station Radio resource far from the boundary resource region 701 in collection 700；When wireless in the first subset of the transmission resource pool 700 The quantity that resource is all scheduled to the UE or remaining idling-resources of mode3 is less than thresholding H1 and/or remaining idling-resource The ratio for accounting for total resources in the first subset of the transmission resource pool 700 is less than H2, then the UE of base station scheduling mode 3 to the side The resource of 701 range of boundary's resource area.
