Specific embodiment
In the embodiment of the present invention, first equipment in occupancy for sending the time interval resource of signal, using non-continuous
Mode carries out signal detection, and non-continuous mode refers to that first equipment is not to carry out in each signal sending cycle
Signal detection, if after detecting the signal that other equipment are sent, reselecting other use in non-continuous signal detection process
In the time interval resource for sending signal.In this way, time slot collision information is provided for first equipment in no adjacent vehicle
In the case where, the case where the first equipment still can detecte the resource collision of oneself, and due to by the way of non-continuous
Collision detection is carried out, time slot can be saved compared to the lasting detection mode for carrying out signal detection in each signal sending cycle
Resource reduces wasting of resources situation.
The embodiment of the present invention is described in further detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, the resource detection method flow chart provided for one embodiment of the invention, comprising the following steps:
S101: the first equipment, for sending the time interval resource of signal, carries out letter in occupancy by the way of non-continuous
Number detection；The non-continuous mode refers to that first equipment is not to carry out signal inspection in each signal sending cycle
It surveys.
Here, the first equipment carries out signal detection by the way of non-continuous；Signal hair can be randomly selected in first equipment
Period progress signal detection namely the first equipment is sent to decide whether to carry out signal inspection in current signal sending cycle at random
It surveys；Alternatively, the first device periodically carries out signal detection, wherein the period for carrying out signal detection is the signal hair of the first equipment
N times of period is sent, N is the positive integer more than or equal to 2.
In specific implementation, the first equipment can occupy in the signal sending cycle of the carry out signal detection of selection
Time interval resource on select a resource block (such as orthogonal frequency division multiplexing (Orthogonal Frequency Division
Multiplexing, OFDM) symbol) it is punched, signal detection is carried out on the resource block of punching.
S102: it after the first equipment detects the signal that other equipment are sent, reselects other for sending signal
Time interval resource.
Here, when the first equipment detects that other equipment send signal on the time interval resource that first equipment occupies
When, that is, resource collision is detected, the first equipment can discharge the time interval resource currently occupied at this time, and competition is other again
Time interval resource.
When in the state that the first equipment is in non-continuous detection, can also receive that other equipment send for this first
The time slot collision information for the time interval resource that equipment occupies determines whether to occur in conjunction with the time slot collision information of other equipment transmission
Resource collision, is specifically shown in the introduction of embodiment two.
As shown in Fig. 2, for another embodiment of the present invention provides resource detection method flow chart, comprising the following steps:
S201: the first equipment, for sending the time interval resource of signal, carries out letter in occupancy by the way of non-continuous
Number detection；The non-continuous mode refers to that first equipment is not to carry out signal inspection in each signal sending cycle
It surveys.
The mode that first equipment carries out signal detection by the way of non-continuous can have following two:
One: the first equipment of mode randomly chooses signal sending cycle and carries out signal detection.
In this mode, the first equipment can decide whether to carry out signal inspection in current signal sending cycle at random
It surveys.
In the specific implementation process, the first equipment can determine first carries out signal detection in each signal sending cycle
Probability, decide whether to carry out signal detection in current signal sending cycle at random based on determining probability.For example, if
The probability that signal detection is carried out in each signal sending cycle that one equipment determines is P (such as 0.5), then the first equipment can be with
Decide whether to carry out signal detection in current signal sending cycle at random as follows:
Assuming that each radio frames includes n time slot, in each radio frames, (signal sends week to vehicle A (the first equipment)
Phase is a radio frames) m-th of time slot on send signal (i.e. the time slot that m-th of time slot is occupied as the first equipment provide
Source), m < n, before m-th of time slot of each radio frames arrives, vehicle A generates a number q in section [0,1] at random,
If q<P, vehicle A normally sends signal on m-th of time slot, if q>=P, vehicle A is punched on m-th of time slot, specifically
Ground, it is assumed that m-th of time slot is divided into 14 resource blocks (OFDM symbol), and vehicle A can randomly choose one on this 14 resource blocks
A resource block is punched, such as is punched on the 13rd resource block, namely other equipment hairs are monitored on the 13rd resource block
The signal sent.If vehicle A listens to vehicle B and also sends signal on m-th of time slot, the time interval resource of vehicle A release busy,
Start to select new time interval resource.
In the specific implementation process, the first equipment determines the probability that signal detection is carried out in each signal sending cycle
When, following manner can be based on:
First equipment determines that each signal sends week according to the third number of devices and/or the 4th number of devices detected
Phase be used to carry out the probability of signal detection；Wherein, the third equipment refers to that the signal of transmission can be by the success of the first equipment
Decoded equipment, the 4th equipment refer to that the signal of transmission reaches the signal power value of the first equipment greater than setting power threshold
Equipment.
In the specific implementation process, if third number of devices and/or the 4th number of devices that the first equipment detects compared with
It is few, for example, if the third number of devices that detects of the first equipment less than the first setting amount threshold, alternatively, detect the
Three number of devices are greater than or equal to the first setting amount threshold, but detect the 4th number of devices less than the second setting quantity threshold
Value, then can decide whether to carry out signal detection in current signal sending cycle with biggish probability at random.
Two: the first device periodically of mode carries out signal detection, wherein the period for carrying out signal detection is described first to set
N times of standby signal sending cycle, N are the positive integer more than or equal to 2.
In the specific implementation process, the first equipment can carry out signal according to certain period on the time interval resource of occupancy
Detection, which is at least 2 times of the signal sending cycle of the first equipment.
For example, vehicle A can be carried out according to the period of the 2 times or more of signal sending cycle using vehicle A as the first equipment
Punching can then punch, so if the signal sending cycle than vehicle A is T on m-th of time slot of this signal sending cycle
It is punched on m-th of time slot being spaced after 2T time slot afterwards.
In the specific implementation process, when the first equipment determines the period for carrying out signal detection, following manner can be based on:
First equipment determines that each signal sends week according to the third number of devices and/or the 4th number of devices detected
Phase be used to carry out the probability of signal detection.
In the specific implementation process, if third number of devices and/or the 4th number of devices that the first equipment detects compared with
It is few, for example, if the third number of devices that detects of the first equipment less than the first setting amount threshold, alternatively, detect the
Three number of devices are greater than or equal to the first setting amount threshold, but the 4th number of devices detected is less than the second setting quantity threshold
Value, then can carry out signal detection with the shorter period on the time interval resource of occupancy.Specifically, it is set using vehicle A as first
Standby, the signal sending cycle of vehicle A is T, then vehicle A can limit period of punching no more than 3T, that is, can only be short
Period 2T or 3T.
S202: it in non-continuous detection process, after the first equipment detects the signal that other equipment are sent, selects again
It selects other for sending the time interval resource of signal.
Here, after the first equipment detects that other equipment send signal on the time interval resource that oneself is occupied, explanation is deposited
Identical time interval resource is being used apart from the closer other equipment of first equipment and first equipment, namely is being provided
Source collision, the first equipment needs start to select new time interval resource at this time.
For example, the vehicle A as the first equipment has listened to the letter with oneself using the vehicle D of identical time interval resource
Number, then the time interval resource of vehicle A release busy, starts to select new time interval resource.
S203: in non-continuous detection process, if the first equipment receives the time slot collision information of the second equipment transmission,
Then when time slot collision information instruction is on the time interval resource that first equipment occupies, the second equipment sends out first equipment
Send signal decoding failure, and from the interference power values of other equipment be greater than or equal to the first interference threshold value when, first
Equipment reselects other for sending the time interval resource of signal；When time slot collision information instruction is when the first equipment occupies
In gap resource, the signal successfully decoded that the second equipment sends the first equipment, but the interference power values from other equipment are big
When the second interference threshold value, the first equipment is switched to lasting mode from non-continuous mode and carries out signal detection,
And enter S204；The lasting mode refers to that first equipment carries out signal detection in each signal sending cycle.
For example, vehicle A in non-continuous detection process, is not heard always and the vehicle that oneself occupies identical time interval resource
, but the time slot collision information of the vehicle C transmission as the second equipment is had received, if time slot collision information instruction pair
The signal that vehicle A is sent decodes failure, and the interference power values from other equipment received are dry more than or equal to first
Threshold value is disturbed, then vehicle A discharges the time interval resource currently occupied, starts to select new time interval resource.If vehicle C send when
Gap collision information indicates the signal successfully decoded sent to vehicle A, but the interference power values from other equipment received are big
In or equal to the second interference threshold value, then vehicle A starts using lasting signal detecting mode, in each signal sending cycle
Detect resource collision.
In the specific implementation process, when the first equipment receives the time slot collision information of the second equipment transmission, analysis should
The decoding cases and disturbed condition of signal are sent indicated by time slot collision information to the first equipment；If the time slot collision information refers to
Show the signal decoding failure that the second equipment sends the first equipment and the signal receives strong jamming (namely from other equipment
Interference power values be greater than or equal to the first interference threshold value), illustrate to have used first equipment occupancy there are other equipment
Time interval resource, and being properly received and (being successfully decoded) for the signal that the second equipment sends the first equipment has been affected, this
When, the first equipment can reselect other for sending the time interval resource of signal.If time slot collision information instruction second is set
The standby signal successfully decoded that first equipment is sent, but the signal receives strong jamming (namely the interference from other equipment
Performance number is greater than or equal to the second interference threshold value, which can be identical with the first interference threshold value, can also
With difference), the time interval resource for illustrating to have used first equipment to occupy there are other equipment, only current second equipment can be with
The signal sent to the first equipment is properly received, and the first equipment can be switched to elder generation from non-continuous mode lasting at this time
Mode carries out signal detection, to detect collision in time, replaces time interval resource.
In above process, the time slot collision information instruction disturbed condition can be explicit instruction, be also possible to implicit
Instruction；For explicit instruction, the second equipment can directly indicate the signal solution sent to the first equipment in time slot collision information
Code failure and from the interference power values of other equipment be greater than or equal to the first interference threshold value, or directly indicate to first
Equipment send signal successfully decoded and from the interference power values of other equipment be greater than or equal to the second interference threshold value, it is right
In implicit instruction, when the time slot collision information explicit instruction decodes failure, it is believed that while implicit instruction is described dry
Disturbing performance number can recognize more than or equal to the first interference threshold value when the time slot collision information explicit instruction successfully decoded
It is greater than or equal to the second interference threshold value for the interference power values of implicit instruction simultaneously.For example, if the second equipment is first
On the time interval resource that equipment occupies, to the signal successfully decoded that the first equipment is sent, and meanwhile it is received dry from other equipment
Performance number is disturbed less than the second interference threshold value, influence is smaller (not to be had it may be considered that other equipment send the signal of the first equipment
Have the time interval resource for occupying the first equipment, or even if occupying, farther out due to distance, influence can be ignored), when not having to send
Gap collision information；If the second equipment decodes failure on the time interval resource that the first equipment occupies, to the signal that the first equipment is sent,
But the received interference power values from other equipment illustrate the interference for being not as other equipment less than the first interference threshold value
Caused decoding failure, it is more likely that be because the first equipment itself apart from second equipment farther out, the second equipment can be at this time
Without the signal that the first equipment of concern is sent, sending time slots collision information is not just had to yet.
Optionally, in the specific implementation process, the first interference threshold value and/or the second interference threshold value can be pre-
The fixed value first set is also possible to pre-define in protocol stack for example, it may be hardware vendor is configured when dispatching from the factory
's.
Alternatively, the first interference threshold value and/or the second interference threshold value are also possible to be dynamically determined by equipment itself
's.Specifically, the first equipment notifies other equipment to adjust according to the third number of devices and/or the 4th number of devices detected
For feeding back the first interference threshold value and/or the second interference threshold value of the time slot collision information.
In the specific implementation process, if third number of devices and/or the 4th number of devices that the first equipment detects compared with
It is few, for example, if the number of devices that can be successfully decoded that the first equipment detects, which is less than third, sets amount threshold, alternatively,
The number of devices that can be successfully decoded is greater than or equal to third and sets amount threshold, but received signal power value is greater than setting power
The number of devices of threshold value can then notify other equipment adjustment for feeding back the time slot collision less than the 4th setting amount threshold
The the first interference threshold value and/or the second interference threshold value of information, the first equipment is also adjustable oneself to be used for other equipment
The the first interference threshold value and/or the second interference threshold value of feedback slot collision information.
Here, the first equipment notify the adjustment of other equipment for the first interference threshold value of feedback slot collision information and/
Or the second interference threshold value, it can refer to notify other equipment only to adjust for the first equipment feedback slot collision information first
Interference threshold value and/or the second interference threshold value can also refer to notify other equipment adjustment for all devices feedback slot
The the first interference threshold value and/or the second interference threshold value of collision information.In addition to this, the first equipment can also adjust oneself to
The the first interference threshold value and/or the second interference threshold value of other equipment feedback slot collision informations, because if the first equipment is examined
The third number of devices and/or the 4th number of devices measured is less, then illustrates that other number of devices around the first equipment are less,
Correspondingly, the surrounding devices quantity of other equipment is also less, therefore, the first equipment can oneself active accommodation it is anti-to other equipment
Present the first interference threshold value and/or the second interference threshold value of time slot collision information.
S204: it in lasting detection process, after the first equipment detects the signal that other equipment are sent, reselects
Other time interval resources for being used to send signal.
For example, if vehicle A in lasting detection process, has listened to the vehicle for using identical time interval resource with oneself
The signal of D, then the time interval resource of vehicle A release busy, starts to select new time interval resource.
S205: in lasting detection process, if the first equipment receives the time slot collision information of the second equipment transmission,
When the letter that time slot collision information instruction is on the time interval resource that the first equipment occupies, and the second equipment sends first equipment
Number decoding failure, and from the interference power values of other equipment be greater than or equal to the first interference threshold value when, the first equipment weight
It newly selects other for sending the time interval resource of signal；When the time slot collision information indicates the time slot occupied in first equipment
In resource, the signal successfully decoded that the second equipment sends first equipment, but the interference power values from other equipment
When more than or equal to the second interference threshold value, the first equipment continues to carry out signal detection by the way of lasting.
For example, the time slot that vehicle A in lasting detection process, has received the vehicle C transmission as the second equipment touches
Information is hit, if the signal decoding failure that time slot collision information instruction sends vehicle A, and what is received sets from other
Standby interference power values are greater than or equal to the first interference threshold value, then vehicle A discharges the time interval resource currently occupied, start to select
New time interval resource.If the time slot collision information that vehicle C is sent indicates the signal successfully decoded sent to vehicle A, but receives
The interference power values from other equipment arrived are greater than or equal to the second interference threshold value, then vehicle A continues using lasting letter
Number detection mode, carries out detection resource collision in each signal sending cycle.
S206: in lasting detection process, if it is not detected in the first setting time length in first equipment
The signal that its equipment is sent, and do not receive time slot collision information, then non-continuous mode is switched to from the lasting mode
Carry out signal detection.
For example, (namely being received certainly as if initiated a switch to after lasting mode carries out signal detection from vehicle A
After the time slot collision information that the vehicle C of two equipment is sent), the signal that other equipment are sent is not detected always in vehicle A, also always
Other time slot collision information are not received, then switch back into non-continuous mode and carry out signal detection, to reduce the wasting of resources.
