Embodiment three
Provide in the present embodiment it is a kind of for V-UE present in V2X systems, random selection send resource P-UE and
The resource pool partitioning model of the P-UE of resource is sent based on part sensing (partial sensing) selection.
For convenience hereinafter:
random P-UE:To be transmitted the P-UE of resource selection using random sources selection mode;
partial sensing P-UE:To carry out the P- of resource selection based on part sensing (partial sensing)
UE;
Randomly choose resource pool:The transmission of resource can be sent using the selection of random sources selection mode wherein for P-UE
Resource pool.
Referring to Fig. 5, resource pool partitioning model is shown in figure, V-UE, which sends resource pool, to be included:The transmission money of lap
Source pond and the transmission resource pool of non-overlapped part.
It should be noted that when if V-UE only used the transmission resource pool of non-overlapped part, V-UE and random P-UE
Transmission resource be independent of each other, the transmission and the transmission of V-UE that can completely avoid random P-UE produce collision.Work as V-
When in the transmission resource of non-overlapped part serious congestion occurs for the business of UE, can because sensing less than it is no it is occupied can
With resource, and cause to send success rate and decline.If the random selection resource pool congestion of random P-UE is not serious at this time, can
V-UE while sensed with configuring in the transmission resource pool of non-overlapped part and the transmission resource pool of lap, allow V-UE
More available transmission resources are obtained, V-UE is improved and sends the transmission success rate that success rate also improves system at the same time.
In current V2X technologies, if some V-UE sensings less than no occupied resource, be allow by
It is transmitted in the resource of occupancy, then the transmission of the V-UE can send with other V-UE and produce collision, and collision may cause to make
It can not be successfully received with the data of one or more V-UE of identical transmission resource.And in the such scheme of the present embodiment,
The V-UE can sense no occupied resource in the random selection resource pool of the lighter P-UE of congestion.
In the transmission resource pool of lap, the induction mechanism of V-UE can ensure to avoid by other P-UE and V-
The transmission resource that UE takes.But random P-UE have certain probability selection by V-UE since random selection sends resource
The resource of occupancy is transmitted and causes to collide, and the probability for colliding generation is related with the Congestion Level SPCC of lap resource pool.Institute
Can not also allow V-UE to use lap resource pool when the transmission resource pool of lap reaches certain thresholding.
V-UE is the Congestion Level SPCC that transmission resource pool is known by CBR measurements at present, and CBR measurements can reflect resource
Occupied ratio, CBR measured values are higher, and explanation Congestion Level SPCC is more serious.So can be by setting rational CBR measured values door
Limit to control whether V-UE is necessary the transmission resource pool using lap, it is specific as follows:
A) thresholding A is more than to the CBR measured values of non-overlapped resource pool, and it is small to the CBR measured values in overlapping part resource pond
When thresholding B, V-UE senses the transmission resource pool of lap at the same time and the transmission resource pool of non-overlapped part is transmitted money
Source selects.
When b) being less than thresholding A to the CBR measured values of non-overlapped resource pool, V-UE, which only senses non-overlapped part resource pool, to carry out
Resource selection is sent, does not allow to send resource pool using lap.
C) random P-UE are all the time using random selection resource pool.
In a particular application, when network can only exist V-UE by assessing in transmission resource pool, in different CBR measured values
The transmission success rate of lower V-UE, while assess and send in resource pool while there are during V-UE and random P-UE, in different CBR
The transmission success rate of V-UE determines the optimal value of above-mentioned CBR measured value thresholding A and thresholding B and is allocated to net under measured value
V-UE in network.
For the transmission resource pool of partial sensing P-UE:
For the P-UE using partial sensing resource selection mechanism, it can also be advised when selection sends resource
Occupied resource is kept away, but if configuration partial sensing P-UE carry out CBR measurements and can increase its power consumption.Institute
, can be with maximum resource utilization rate the transmission resource pool that partial sensing P-UE share V-UE can be configured.
In practical applications, it is contemplated that P-UE is electrically more demanding to province and the power consumption of P-UE can be increased by carrying out CBR measurements,
P-UE not necessarily supports the function that CBR is measured.If partial sensing P-UE support to carry out CBR measurements, can make
With the above-mentioned mechanism identical with V-UE to determine whether the resource sent in resource pool of lap can be used.If P-UE
Do not support to carry out CBR measurements, then partial sensing P-UE do not support to carry out CBR measurements, then only allow it to use non-heavy
Folded part resource pond.
The resource of partial sensing P-UE for supporting CBR measurements selects management method as follows:
A) thresholding C is more than to the CBR measured values of non-overlapped resource pool, and it is small to the CBR measured values in overlapping part resource pond
When thresholding B, partial sensing P-UE send resource pool using the distribution of overlapping and non-overlapping portion at the same time.
When b) being less than thresholding C to the CBR measured values of non-overlapped resource pool, partial sensing p-UE can only use non-
Lap resource pool is transmitted resource selection, does not allow to send resource pool using lap.
The resource of partial sensing P-UE for not supporting CBR measurements selects management method as follows:
A) resource pool is sent using non-overlapping portion distribution.
In the present embodiment, P-UE can be based on remaining capacity selection and send resource pool.
Selected compared to random sources, part senses the more power consumption of (partial sensing) mechanism, due to the electricity of P-UE
It is limited, when remaining capacity than it is relatively low when, it should reduce V2P business power consumption ensure P-UE other services can normally into
OK.The transmission resource pool that P-UE can be controlled to use by way of configuring electricity thresholding, for transmission can be randomly choosed
Resource can also select to send the P-UE of resource based on partial sensing, specifically:
When P-UE remaining capacities are more than threshold value, the P-UE of partial sensing is supported to be based on partial
Sensing is transmitted resource selection.
When P-UE remaining capacities are less than threshold value, selection transmission resource in P-UE random selection resource pools.
It should be noted that when dividing resource pool, the history average traffic that network may be referred to V-UE in system comes
Determine the transmission resource pool of the non-overlapped part of V-UE, the lap of V-UE is determined by the history bursty traffic of V-UE
Transmission resource pool size.Simultaneously as overlapping send the use condition of resource different from non-overlapping portion distribution, the transmission of V2X
Resource pool configuration signal needs to indicate respectively that the distribution of overlapping and non-overlapping portion send resource pool to configure
In the present embodiment, the overlapping and non-overlapped part resource pool of above-mentioned V-UE is included in V2X resource pools configuration signal,
And random selection resource pool configuration.
V-UE needs to obtain the lap of V-UE and non-overlapped part resource pool and the configuration for randomly choosing resource pool
Not only support random sources to select but also support the P-UE for carrying out resource selection based on partial sensing to need to obtain
The configuration of the non-overlapped part resource pool and random selection resource pool of V-UE.
The P-UE of random sources selection is only supported to need to obtain the configuration of random selection resource pool.
