QoS class letter (QoS Class Identifier, abbreviation QCI)) determines the priority and the tune to UE of UE business
Degree.
Embodiment two
This alternative embodiment provides a kind of Semi-static scheduling method, including base station sends the control signaling for indicating scheduling result,
And/or distribution UE sends the resource of business.
In this alternative embodiment, it can use based on time delay T1 scheduling, the scheduling includes：Business is sent in scheduling UE
Subframe and the subframe that sends control signaling of base station between time delay be T1, Fig. 8 is according to alternative embodiment two of the present invention
In the schematic diagram dispatched based on time delay T1, as shown in figure 8, for example, taking T1 for 8 sub- frame lengths, then base station is issued
After PDCCH 8 subframes of subframe delay, corresponding subframe is to be scheduled to the subframe that UE sends V2X, and UE is opened
The transmission first of beginning SPS transmission.Also, before SPS scheduling is re-started, according to the selection pair of SPS transmission cycles
The subframe answered sends V2X message.Such as, it is assumed that the SPS transmission cycles of V2X business configurations are 100ms, and base station exists
Radio frames #1 subframe 5 issues PDCCH, then UE transmits V2X message first in radio frames #2 subframe 3,
Next V2X message is sent in radio frames #102 subframe 3.
Or, based on time delay T2 scheduling, including：The scheduling to UE is completed within time delay T2, UE is being received
Time delay between the dispatch request SR and/or reporting cached state BSR of transmission subframe and the subframe for sending PDCCH is
T2, Fig. 9 be according in alternative embodiment two of the present invention based on time delay T2 dispatch schematic diagram, as shown in figure 9, for example,
It is 10 sub- frame lengths to take T2, then base station completes to dispatch UE SPS after the SR of UE transmissions is received,
And postponing the subframe corresponding to 10 subframes, PDCCH is sent, is that UE indicates scheduling result.UE is being received
After PDCCH, 4 subframes of delay start the transmission first of SPS transmission.Also, dispatch it re-starting SPS
Before, select corresponding subframe to send V2X message according to SPS transmission cycles.
Or, based on time delay T3 scheduling, including：T3 is that UE sends the subframe of business and receives control signaling place
In the time delay of subframe, the control information carried included in control signaling.
For example, a kind of DCI format, includes the instruction for the time delay T3 that V2X message is sent to UE.Such as, T3 takes
13 subframe lengths, then UE receive PDCCH, solve after DCI, obtain T3 value, and existed according to T3 value
Postpone to start the transmission first that SPS is transmitted after 10 subframes.PDCCH such as is received in radio frames #N subframe 4,
Then UE starts to send V2X message in radio frames #N+1 subframe 7.Also, before SPS scheduling is re-started,
Corresponding subframe is selected to send V2X message according to SPS transmission cycles.
Or, based on time delay T4 scheduling, including：Receiving the dispatch request SR and/or buffer status of UE transmissions
The time delay for reporting BSR subframe and scheduling UE to send between the subframe of business is T4, and Figure 10 is optional according to the present invention
The schematic diagram dispatched in embodiment two based on time delay T4, as shown in Figure 10, it is assumed that T4 is 20ms, then base station connects
After the SR for receiving UE transmissions, UE is dispatched to the corresponding subframes of delay 20ms and sends V2X message, and is being prolonged
The corresponding subframes of 16ms send PDCCH late.Such as, base station receives UE transmissions in radio frames #N subframe 3
SR, scheduling UE proceed by SPS transmission V2X message in radio frames #N+2 subframe 3, and in radio frames #N+1
Subframe 9 send PDCCH.
Or, based on time delay range [T5, T6] scheduling, including：Receiving the dispatch request SR of UE transmissions and/or delaying
Deposit state reporting BSR subframe and UE send business subframe between time delay be more than or equal to time delay T5, be less than or
