Furtherly new formatX may also include the further distribution information of schedule information, the scheduling The resource block instruction of resource further comprises distribution information, such as described configured information is 2bit, then 00 represents 190B and 300B resource blocks are expressed as two 190B resource block, 01,10 are expressed as 300B resources Block and 190B resource blocks, 11 are expressed as two 300B resource block etc..

Furtherly new formatX also includes conventional control information, and such as modulation intelligence is (if using system One modulation intelligence or high-level signaling mode, then without this field), the control parameter such as power parameter.

Specific implementation process includes：

Step 1：Base station notifies V2X terminals, the system broadcasts in coverage by system broadcast message At least one set of V-RNTI for blind check is included in message；

Or, base station and V2X terminals are pre-configured with least one set of V-RNTI by predefined mode；

Or, when setting up V2X with V2X terminals in base station and linking, pass through RRC signaling and notify V2X whole Hold at least one set of V-RNTI for blind check PDCCH；

Wherein, at least one described V-RNTI can be determined or according to business data packet according to the grade of service Size determines either to determine its corresponding relation or at least one described V-RNTI of random selection by groups of users In a V-RNTI, the remaining V-RNTI of selection after selected V-RNTI is occupied.

For example：By traffic packets V-RNTI1 is used in emergency pedestrian and vehicle interactive information；Not Alarm is sent under evitable conflict situations and uses V-RNTI2；V2I message is transmitted by eNB to use V-RNTI3。

Step 2：V2X terminals are pre-configured with or passed through by system broadcast message or by predefined mode RRC signaling obtains at least one set V-RNTI.

Step 3：When V2X terminals are ready for sending uplink information, blind check PDCCH, PDCCH's (such as V2X is touched for the specific search space or low time delay business of public search space or the V2X terminals Hair style business) dedicated search space use format0, format4 or format X and corresponding V-RNTI Retrieve available uplink scheduling information；If CRC check success, V2X terminals know that this information is Required for oneself, then uplink scheduling information is further decoded, obtain ascending resource.

When the ascending resource of acquisition is more than resource needed for V2X user, V2X terminals can be according to the upper of instruction Row resource size, and buffering (buffer) state are selected in indicated resource by predefined resource block Beginning resource.For example, the resource that low time delay business is specified further is divided by frequency domain after the first time domain of subframe, each Resource is predefined size or knows its size by V-RNTI, and V2X terminals are selected according to random selection principle One of resource is selected as ascending resource and enters row information transmission.

For example, pre-allocated recourses block is 190RB, a subframe 16PRB can be taken, its RNTI is used V-RNTI1, is a subframe 32PRB by the PDCCH resources configured, then V2X terminals can be selected The top half of the frequency domain resource of its resource block is transmitted, or selects the lower half of the frequency domain resource of its resource block Part is transmitted；
