In one aspect, vehicle UE 410,415,420,425,430 can be supported in reliability, range, delay and medium
Access aspect provides the priority mechanism of different characteristics.In one example, it can be provided to the communication of higher priority as follows
Transmission spectrum resource, these transmission spectrum resources provide the better radio quality of communication than more low priority.At another
In example, the communication that higher priority is more frequently sent than the communication of more low priority can permit.In one aspect, to small
The priority of section V2V communication supports to may include the priority processing based on vehicle UE report.
In the priority processing reported based on vehicle UE, one or more vehicle UE 410,415,420 can be to each
Service eNB 440,445 report the resource set used by one or more adjacent vehicle UE 425.In one aspect, each vehicle
UE can monitor the transmission of adjacent vehicle UE.For example, vehicle UE 415 can sense the vehicle UE neighbouring with vehicle UE 415
410,420 and 430 transmission.However, vehicle UE 415 possibly can not sense the transmission of vehicle UE 430, because it is not in vehicle
In the receiving area of UE 415.In one aspect, vehicle UE can detecte the excellent of the different transmission from each adjacent vehicle UE
First grade.
In one aspect, each vehicle UE in the range of eNB, vehicle UE can be reported and is used about adjacent vehicle UE
In the information of the resource of one or more communication priorities.For example, vehicle UE 415 can in the range of 435 eNB, and
Resource of the vehicle UE 410 and 425 neighbouring with vehicle UE 415 for priority traffic can be sensed.In one aspect, eNB
The information that receives from vehicle UE be can use to distribute and/or redistribute resource to be used for and one or more priority phases
Associated use.
In one aspect, in order to make it possible the report based on vehicle UE, which the vehicle UE reported can identify
Each of one or more priority transmissions of a cell scheduling.In an example, priority transmission may include spy
Due to the information of cell, information (SCI), medium access control (MAC), radio link control such as are controlled in sidelinks
(RLC) in it is manifestly intended that with physical side link control channel/pond physical side link shared channels (PSCCH/PSSCH),
Configuration or pilot frequency mode impliedly associated cell identifier.In an example, vehicle UE can be used to service eNB notice
In the information specific to cell of one or more priority transmissions.
On the other hand, not specific to the information of cell, vehicle UE can be reported about being monitored
For giving the information of the resource of the transmission of priority.In an example, vehicle UE can collect the money for priority communication
Source information, and it is reported together with group identifier, LI identifier, source and destination identifier or address to each eNB.It is each
ENB can determine whether reported information is related to the transmission from other cell schedulings.The tune of their own is known in view of each eNB
Decision is spent, eNB can be transmitted with neighbor identification.
In one aspect, vehicle UE can in response to one or more scheduled events and/or periodically for one or
Multiple priority automatically report detected precedence information and associated resource measurement.On the other hand, eNB can be with
Report precedence information and associated resource measurement are configured (for example, measuring in the resource of PSCCH/PSSCH by vehicle UE
Received signal strength indicator symbol or receive reference signal power level).In yet another aspect, vehicle UE can be in response to coming
Precedence information is reported from the explicit request of each eNB.
In one aspect, window can be distributed by sensing window, transmission window, transmission window period, semipersistent resource
Vehicle UE sensing operation is characterized with sidelinks semi-persistent scheduling (SPS) process.In one aspect, sensing window can be vehicle
UE is used to monitor and collect the information of the PSCCH transmission from other vehicles UE and carries out the subframe collection of corresponding energy measurement.
Window, which can be, to be predefined or be preconfigured in the case where operation outside coverage area by specification by network configuration.Sense
Survey window can be common between vehicle UE.Sensing window in order to adapt to the low V2V message rate of 1Hz, in an example
The mouth duration can be 100ms, 1000ms or higher magnitude.
In one aspect, transmission window can be subframe collection, and wherein vehicle UE executes resource selection for including potential
Retransmit the transmission of the transmission block (TB) including (for example, grouping transmission window).Transmission window can be can be by network configuration, quilt
Specification is predefined or is preconfigured for operating outside coverage area.In an example, transmission window length can be less than
100ms, to meet V2V deferred constraint.However, representative value may be in the range of 5ms to 500ms.
In one aspect, the transmission window period can be resource allocation cycle, and there is semipersistent resource to distribute window for instruction
The periodicity of the transmission window (for example, grouping transmission window) of mouth.The transmission window period can be with V2V message generating rate pair
Together, and meet the delay requirement that periodical flow transmits.
In one aspect, semipersistent resource distribution window can be the parameter specific to vehicle UE, can depend on vehicle
The flow rate mode of the side UE.The maximum value of the window can be can by network configuration or independently determined by vehicle UE.In general, half
The value of persistent resource allocation window can be limited and can be in the range of 100ms to 1000ms, to cope with vehicle
Mobility effect in environment.
In one aspect, sidelinks SPS process is for transmitting PSCCH and PSSCH in semipersistent resource distribution window
The process specific to UE.Vehicle UE can trigger multiple SPS processes, and each SPS process distributes window phase with semipersistent resource
It is associated with and is carried in semipersistent resource distribution window.
In one aspect, it in order to support the priority in primary resource selection mode, can be exchanged between vehicle UE excellent
First grade information.In order to support each priority different stage transmission quality, the precedence information collected by vehicle UE can be with
A part of primary resource gravity treatment as vehicle UE.
In one aspect, sidelinks control information (SCI) decoding and energy measurement support can be used for sensing and vehicle UE
Primary resource selection.To for sense and the SCI of resource selection it is decoded support can be used for transmitting precedence information.SCI
Receive can than data channel more robust, therefore may be advantageously used with instruction priority.In addition, SCI has bigger communication
Range, this is for being used to ensure that the priority processing of transmission quality is important.Instead of the explicit signaling in SCI, can also incite somebody to action
Some SCI resources are associated with priority or precedence information is put into shared transmission.However, in this case,
It is likely to reduced the SCI stock number for each priority, and may need to distribute additional resource for each priority.Cause
This, explicit signaling mechanism may be preferred, it is possible to which one to three newer field is added to instruction transmission priority
New SCI format (for example, SCI format 1).In such a case, it is possible to support 2,4 or 8 priority.
In one aspect, the sensing process of vehicle UE is independent of priority.Vehicle UE can be executed independently of priority
Sensing process.However, the condition of resource selection may be different different priority, and matched by higher protocol layer
It sets.On the other hand, for the exception-triggered situation for needing to immediately access resource of such as vehicle collision etc, vehicle UE can be with
Medium is accessed, but regardless of for the preconfigured resource selection condition of each priority.Therefore, eNB can configure vehicle UE to
Sensing process is skipped for high priority transfer and other exception-triggered situations, to access medium with the minimum delay.
In one aspect, high priority transfer may in terms of transmission range, interference protection and to the preferential access of medium
Need better transmission quality condition.Many principles can be considered in the priority and resource selection process of V2V communication.A side
Face, these principles may include that the candidate resource collection specific to priority based on the condition specific to priority constructs.Another
On the one hand, the condition specific to priority for constructing specific to the candidate resource collection of priority can be matched by more higher protocol layer
It sets.These configurations are it is contemplated that for excluding and/or including the resource occupied by the higher priority transmission of candidate resource collection
Condition (for example, measurement and threshold value).Candidate resource collection may include received signal power, with reference to received signal strength threshold value and its
He is similar to measure.Similarly, configuration is it is contemplated that for excluding and/or including being accounted for by the more low priority transmission of candidate resource collection
The condition of resource.It on the other hand, can be based on randomization resource selection specific to the candidate resource collection of priority.Again
On one side, detect with higher priority transmission resource contention can detect on frequency spectrum resource conflict it is low or high

The priority of selection gives the high-energy subframe with null resource.
In one aspect, can make specific to the resource selection randomization in the candidate resource collection of priority, to consider to account for
With the precedence information of other transmitters of the resource in the candidate resource collection specific to priority identified.For example, can be with
With the resource that the selection of more high probability is occupied by the transmission of more low priority, and can select to be transmitted by higher priority with more low probability
The resource of occupancy.On the other hand, independently of priority, the resource in candidate resource collection can be selected with identical priority.

Conflict, then it can trigger resource reuse adoption process.It in an example, can be for temporal conflict (such as in same son
Frame but be not necessarily in same frequency resource clashes) triggering gravity treatment.In another example, time and frequency can be directed to
On conflict triggering gravity treatment (is such as clashed) in the distribution of specific time-frequency.In one aspect, it is carried out with low priority
The vehicle UE of transmission can abandon the grouping of the transmission in pre-assigned semi-durable transmission window, or only abandon and another vehicle
The transmission grouping that the higher priority transmission of UE clashes.
In one aspect, the mechanism for notifying the high priority transfer for selected priority can be provided.It is high
Priority transmission may need high reliability in terms of reception.In order to improve primary resource selection in high priority transfer can
By property, vehicle UE can execute the notice about other UE higher priority transmission detected.Informing mechanism can indicate height
The resource that priority transmission is utilized, so that the transmission environment in these resources is due to sensing and ongoing resource gravity treatment
Journey and become less congestion.In an example, the adjacent vehicle UE that resource reuse adoption process is executed in neighborhood can be attempted simultaneously
The resource for avoiding selection high priority transfer from being utilized, to reduce interference problem and increase the height in interference-limited scene preferentially
The coverage area of grade transmission.Vehicle UE can simply relay the SCI letter of (for example, relaying and decoding) higher priority vehicle UE
Number, to reproduce the content of the original SCI signal of high priority vehicle UE transmission.In one aspect, eNB, which can be configured, to send out
