Specific embodiment
The UE of V2X communication is carried out there may be following situation, is assigned with for it money for carrying out V2X communication in eNB
Behind source, in the corresponding transmission cycle of the resource, there is no enough data to be transmitted by UE, therefore, the value of counter
It is not decremented to 0, and when the value of counter is not decremented to 0, eNB cannot redistribute resource to the UE, and transmission opportunity is at any time
Passage all lose, thus, so that the utilization rate of resource is not high.
The application is after UE is assigned with the resource for carrying out V2X communication in order to improve the utilization rate of resource, in eNB,
In the corresponding transmission cycle of resource, in conjunction with channel status, the transmission cycle of adjustresources, as UE redistribute resource, from
And so that resource allocation is more reasonable, improve resource utilization.
Be described in detail below with technical solution of several specific embodiments to the application, below these are specific
Embodiment can be combined with each other, and the same or similar concept or process may be repeated no more in some embodiments.
Fig. 1 is the application scenarios schematic diagram of the application, as shown in Figure 1, include eNB and UE in the application scenarios of the application,
ENB is that UE distributes the resource for carrying out V2X communication, and the Physical Uplink Shared Channel for reporting channel state
(Physical Uplink Shared Channel, PUSCH) resource etc., the resource communicated for V2X that UE is distributed according to eNB
V2X communication is carried out, and obtains channel status in the corresponding transmission cycle of resource, is reported in the PUSCH resource of eNB distribution to eNB
Channel status, so that eNB adjusts the transmission cycle of UE according to channel status.
It for ease of description, is corresponding transmission before the resource updates of UE distribution by eNB in the following each embodiments of the application
Period is known as the first transmission cycle, and corresponding transmission cycle is known as the second transmission cycle after update.
Fig. 2 provides a kind of flow diagram of resource allocation method embodiment for the application, as shown in Figure 2:
S201:eNB receives the channel state indication channel that UE is reported.
Wherein, channel state indication channel is used to indicate UE between the adjacent transmission opportunity twice in the first transmission cycle
Resource retain and be spaced corresponding channel status.Channel status be it is busy or idle, when channel status be it is busy when, illustrate letter
Road resource is more in short supply；When channel status is idle, illustrate that channel resource is relatively more more than needed.
Wherein, the transmission opportunity number in the first transmission cycle selects transmission count value to determine according to first resource.
Wherein, first resource selection transmission count value is configured by eNB, it is assumed that and it is S1 that first resource, which selects transmission count value,
The then transmission opportunity number C1 in the first transmission cycle:
C1=10*S1
Wherein, resource is separated by between adjacent transmission opportunity twice and retains interval, S1 is random whole by high-rise one configured
Number, value size depend on the size that resource retains interval, for example, when resource retains interval and is greater than or equal to 100ms, S1
Value between [5,15]；When resource, which retains interval, is equal to 50ms, the value of S1 is between [10,30]；When resource retains
When interval is equal to 20ms, the value of S1 is between [25,75].
Assuming that: resource is divided into 100ms, S1 13 between retaining, then the transmission opportunity number in the first transmission cycle is 130
Secondary, the first transmission cycle is as shown in figure 3, Fig. 3 is a kind of schematic diagram for the resource for carrying out V2X communication that eNB is UE distribution.
Its transmission cycle arrives subframe m+129*100, each transmission opportunity accounts for a subframe, every to protect by first resource since subframe m
It remains spaced, transmission opportunity reduces primary.
The mode that UE obtains channel state indication channel is as follows:
UE enters wireless heterogeneous networks connection (Radio Resource Control Connected, RRC-
CONNECTED) state, UE listen to the resource between adjacent transmission opportunity twice and retain the corresponding channel in interval, and each resource is protected
Spacing obtains the busy rate of channel (Channel Busy Ratio, CBR), and the CBR compared and eNB are UE pre-configuration
Side chain road received signal strength indicator (Sidelink-Received Signal Strength Indication, S-RSSI)
The size of threshold value indicates comparison result with 1 bit, such as: indicate that comparison result is that CBR is greater than S-RSSI with 1, with 0 table
Show that comparison result is CBR no more than S-RSSI；Alternatively, indicating that comparison result is that CBR is greater than S-RSSI with 0, use 1 indicates to compare knot
Fruit is that CBR is not more than S-RSSI, in this regard, the application is with no restrictions；When CBR be greater than S-RSSI then indicate channel status be it is busy,
Conversely, channel status is the free time.
The mode of UE to eNB reporting channel state instruction information includes but is not limited to following possible implementation:
Wherein, a kind of possible implementation is as follows:
ENB can distribute each resource to UE and retain corresponding 1 bit in interval by way of semi-persistent scheduling
PUSCH resource, for example, eNB with resource retain between be divided into the period, periodically be UE distribute 1 bit PUSCH resource；ENB
It may be calculated once for UE and distribute the PUSCH resource that multiple resources retain corresponding 1 bit in interval, in this regard, the application does not limit
System.
UE reports corresponding resource to retain the channel state indication channel being spaced by the PUSCH distributed.
S202:eNB determines the second transmission cycle according to channel state indication channel.
When channel state indication channel indicates channel idle: a kind of possible implementation: not adjusting transmission cycle.Separately
A kind of possible implementation: extending transmission cycle, in this kind of implementation, can be combined with the data volume that UE needs to transmit
Size extend transmission cycle when UE needs the data volume transmitted more, thus, shorten for the carry out V2X of UE distribution it is logical
When the inadequate resource of letter, the problem of redistributing resource for UE, bring time delay.Wherein, the size for the data volume that UE needs to transmit
Can by being compared determination with preset threshold, can also by with the remaining resource communicated for V2X distributed for UE
Size determine, in this regard, the application is with no restrictions.
When channel state indication channel instruction channel is busy, a kind of possible implementation: shorten transmission cycle, at this
In kind implementation, the size for the data volume that UE needs to transmit can be combined with, such as: when the data volume that UE needs to transmit is less
When, then shorten transmission cycle, thus, improve resource utilization.
The present embodiment receives the channel state indication channel that UE is reported by eNB, according to channel state indication channel, really
Fixed second transmission cycle, thus, it is after UE is assigned with resource, in the corresponding transmission cycle of resource, in conjunction with channel shape in eNB
Whether state, the transmission cycle of adjustresources, as UE redistribute resource, be 0 without regard to count value, thus, so that money
The distribution in source is more reasonable, improves resource utilization.
Fig. 4 provides the flow diagram of another resource allocation method embodiment for the application, as shown in figure 4, Fig. 4 be
On the basis of embodiment illustrated in fig. 2, the description of a kind of possible implementation of S202, wherein transmission cycle is selected according to resource
It selects transmission count value to determine, therefore, the size that count value can be transmitted by adjusting resource selection adjusts transmission cycle, such as Fig. 4
It is shown:
S2021:eNB determines Secondary resource selection transmission count value according to channel state indication channel.
Channel state indication channel indicates channel busy or free time.
When channel state indication channel instruction channel is idle:
A kind of possible implementation, eNB do not redistribute the resource for carrying out V2X communication to UE.
Alternatively possible implementation, eNB retains in resource to be spaced in corresponding resource selection transmission count value section,
Selecting one to be greater than first resource selects the numerical value of transmission count value to select transmission count value as Secondary resource, thus, increase
It is UE distribution for carrying out the resource of V2X communication.It is more that this kind of implementation is relatively specific for the data that UE needs to transmit
Situation, thus, when shortening the inadequate resource for the progress V2X communication of UE distribution, resource is redistributed for UE, brings time delay
Problem.
When channel state indication channel instruction channel is busy:
ENB, which then retains in resource, to be spaced in corresponding resource selection transmission count value section, selects one to provide less than first
Source selects the numerical value of transmission count value to select transmission count value as Secondary resource.
S2022: transmission count value is selected according to Secondary resource, determines the second transmission cycle.
When channel state indication channel instruction channel is idle:
Assuming that it is S2 that Secondary resource, which selects transmission count value, then the transmission opportunity number C2 in the first transmission cycle:
C2=10*S2；
Assuming that S1=13, S2=14, then the first transmission cycle arrives subframe m+129* as shown in figure 3, since subframe m
100；Second transmission cycle arrives subframe m+139*100 since subframe m, as shown in figure 5, it is UE distribution that Fig. 5, which is the application eNB,
For carry out V2X communication resource another schematic diagram.To, extend transmission cycle, shorten for UE distribution into
When the inadequate resource of row V2X communication, the problem of redistributing resource for UE, bring time delay.When channel state indication channel indicates
When channel is busy:
Assuming that it is S2 that Secondary resource, which selects transmission count value, then the transmission opportunity number C2 in the first transmission cycle:
C2=10*S2；
Assuming that S1=13, S2=8, then the first transmission cycle arrives subframe m+129*100 as shown in figure 3, since subframe m；
Second transmission cycle arrives subframe m+79*100 since subframe m, as shown in fig. 6, it is being used for for UE distribution that Fig. 6, which is the application eNB,
Carry out another schematic diagram of the resource of V2X communication.To shorten transmission cycle, improve resource utilization.Meanwhile it counting
Value is also reset as 8.
The present embodiment receives the channel state indication channel that UE is reported by eNB, according to channel state indication channel, really
Determine Secondary resource selection transmission count value, transmission count value is selected according to Secondary resource, determines the second transmission cycle, thus,
ENB is that UE is assigned with after resource, in the corresponding transmission cycle of resource, in conjunction with channel status, and the transmission cycle of adjustresources,
As UE redistributes resource, thus, improve resource utilization.
Fig. 7 is the flow diagram of another resource allocation method embodiment provided by the present application, and Fig. 7 is shown in Fig. 4
On the basis of embodiment, further, can also include: after S2022
S203:eNB determines the second transmission opportunity frequency threshold value according to the second transmission cycle and preset ratio.
Transmission opportunity frequency threshold value refers to, in a transmission cycle, when the number that UE does not carry out V2X communication continuously is equal to
When the transmission opportunity frequency threshold value, eNB can reconfigure resource for UE.
A kind of possible method of determination of transmission opportunity frequency threshold value, it is determining according to the second transmission cycle and preset ratio,
Such as: the transmission opportunity number in the second transmission cycle is 80 times, preset ratio 0.4, the second transmission opportunity frequency threshold value=
80*0.4=32 times.Wherein, preset ratio can be a fixed value, be also possible to eNB according to channel state indication channel
The value of UE is distributed to, in this regard, the application is with no restrictions.
Transmission opportunity frequency threshold value is also possible to a preset constant, for example, in transmission opportunity number in [50,100]
Between, transmission opportunity frequency threshold value is 20 times, and in transmission opportunity number between [101,150], transmission opportunity frequency threshold value is
52 times, in this regard, the application is with no restrictions.
S204: in the second transmission cycle, if the continuous n times of UE do not carry out V2X communication, resource is reconfigured to UE.
Wherein, N is equal to the second transmission opportunity frequency threshold value, and N is the certificate more than or equal to 1.
In the present embodiment, by eNB according to transmission cycle and preset ratio, determines transmission opportunity frequency threshold value, transmitting
In period, if the number that UE does not carry out V2X communication continuously is greater than transmission opportunity frequency threshold value, eNB reconfigures resource, and nothing
Need to consider whether count value is 0, thus, improve resource utilization.
In conjunction with the various embodiments described above, eNB is that UE re-starts resource distribution, including following several situations, wherein a kind of feelings
Condition is to be determined to re-start resource distribution according to channel state indication channel, and another situation is according to transmission opportunity frequency threshold value
