It is as briefly mentioned above, in order to realize that V2P (or P2V) communicates, vehicle-mounted UE and pedestrian in such as cell or region
UE needs constantly to record the traveling packet of itself travel information using the resource pool in described region to send.However,
Pedestrian UE can not determine to distribute to the congestion condition of the resource pool of specific region in cell.Specifically, vehicle-mounted UE generally has
Continuous power is supplied and relatively frequently (for example, every 100 milliseconds) send packet of once advancing, and therefore can receive resource
The traveling packet that other UE in pond are sent.So, vehicle-mounted UE is capable of the congestion level in estimating resource pond, and then can take
Congestion control means alleviate the congestion of resource pool.
Pedestrian UE then generally has a certain degree of power limit, so in order to reduce power consumption, pedestrian UE sends data
The frequency of bag is substantially less than vehicle-mounted UE, such as every 1 second just sends once.Moreover, pedestrian UE does not receive the traveling of other UE transmissions
Packet.Therefore, pedestrian UE can not by traveling packet that other UE are sent come the congestion level of direct estimation resource pool, from
And can not solve the congestion due to resource pool and caused by traveling packet send the situation of congestion.
However, congestion level information is crucial input for congestion control.Due to congestion condition can not be determined, OK
People UE can not independently solve the congestion due to resource pool and caused by traveling packet send the situation of congestion.Therefore, it is necessary to one
Kind of scheme allows pedestrian UE to obtain congestion level information, so that pedestrian UE can be directed to P2V communicates and realize congestion control.
In order to solve these and other potential problems, embodiment of the disclosure provides a kind of mechanism for congestion control, and it is helped
Congestion level information is obtained with the help of vehicle-mounted UE of the walk help people UE in the same area.
In general, in accordance with an embodiment of the present disclosure, estimate congestion level by one or more vehicle-mounted UE first and select
Congestion level report is sent to the network equipment of such as base station to selecting property.Then, base station handles the congestion level letter of these reports
Breath, and broadcast related congestion level to pedestrian UE.Pedestrian UE adjusts configured transmission based on the congestion level of broadcast, so as to real
Congestion control in existing transfer resource pond.
To discuss convenient purpose, embodiment of the disclosure is discussed below in conjunction with " region " in cell.As known to
, in wireless access stratum reticulare 2 (RAN2), having arranged the mapping in geographical position and resource can be done in area concept.
Moreover, area concept can be implemented in cell level.It is understood that embodiment of the disclosure can also be directly in cell
Level applications.In other words, a region in cell can be whole cell in itself.Moreover, embodiment of the disclosure can borrow
Help to support the interface of direct communication between UE to complete, such as PC5 air interfaces.However, the present invention can also by adaptation and
It is suitable for other communication modes, and is not limited to vehicle UE and pedestrian UE.
Fig. 1 shows the communication environment 100 that embodiment of the disclosure can be implemented within.As shown in fig. 1, communication loop
Border 100 includes cell 105, two regions that cell 105 includes base station 110 and has been divided, i.e. region 1 120 and area
Domain 2 130.Region 1 120 includes multiple UE, i.e. UE1 120-1, UE2 120-2, UE3 120-3 and UE4 120-4.Area
Domain 2 130 can equally include multiple UE, i.e. the 130-2 of UE5 130-1 and UE 6.The network equipment (for example, base station) 110 can be with
Communicated with the 130-2 of UE1 120-1 to UE 6 in cell 105, such as transmission region configuration, etc..As an example, institute in Fig. 1
The UE shown can include vehicle-mounted UE or pedestrian UE.Certainly, other kinds of terminal device is also possible.
Region configuration includes the resource pool on the information in region 120 or 130 and the association in region 120 or 130.Cell
The 130-2 of UE1 120-1 to UE 6 in 105 can determine which region it belongs to based on self-position and region configuration.Should
Work as understanding, the number of the UE shown in Fig. 1 is merely for illustrative purposes and has no intention to limit.It can include appointing in each region
Anticipate an appropriate number of UE.It should be appreciated that the region in cell is divided smaller, between the UE in the region it is farthest it is relative away from
From just smaller, so that the congestion water of the resource pool in the region that pedestrian UE is obtained by the vehicle-mounted UE in the same area
It is flat more accurate.
As described above, the 130-2 of UE1 120-1 to UE 6 in cell 105 can include for example vehicle-mounted UE and pedestrian UE.
The power limit that vehicle-mounted UE does not have power limit or is subject to is smaller, and be therefore able to carry out transmission to traveling packet and
Receive the two.Therefore, scheduling assignment (scheduling can be passed through by the transfer resource pond in monitor area, vehicle-mounted UE
Assignment, SA) decode the congestion level for coming direct estimation transfer resource pond with energy measurement.
Fig. 2 shows the conceptual data flow graph 200 of the method for congestion control in certain embodiments.As schemed
Show, the 120-1 of UE 1 (for example, vehicle-mounted UE) determine the estimation congestion water in the transfer resource pond in the region of (202) belonging to it
It is flat.Then, the 120-1 of UE 1 send the congestion level report of (204) instruction estimation congestion level to the network equipment 110.Receiving
After being reported to congestion level, the network equipment 110 is based at least partially on estimation congestion level to determine the congestion of (206) resource pool
Horizontal information, and broadcast (208) to the UE2 120-2 (for example, pedestrian UE) that can not directly sense resource pool congestion level and gather around
Fill in horizontal information.UE2120-2 can adjust (210) certainly after the congestion level information of broadcast is received according to congestion level
The configured transmission of body.
As illustrated, in certain embodiments, more UE can be participated in said process.The operation that these UE are performed
It is alternatively, and to be therefore represented by dotted lines in fig. 2.Specifically, in the illustrated example shown in fig. 2, UE3 120-3 are for example
It is vehicle-mounted UE, and the resource pool congestion level of its estimation therefore can be sent to the network equipment 110.In such embodiment
In, what following article also will be described, the network equipment 110 can determine (206) congestion level based on more sample estimateses, so as to
Improve accuracy.UE4 120-4 are, for example, pedestrian UE, and the congestion water of (208) can be broadcasted by receiving the network equipment 110
Ordinary mail is ceased to know congestion level indirectly, and corresponding adjustment (210) is made to configured transmission.These UE property and operation
It is identical with 120-1 the and UE2 120-2 of UE 1 respectively, it will not be repeated here.
It should be appreciated that the number of the UE shown in Fig. 2 is merely for illustrative purposes and has no intention to limit.And Fig. 2 institutes
The various processes shown and action (for example, UE2 120-2 and UE4120-4 based on congestion level information receive, broadcast come
Adjust configured transmission of itself etc.) also it is merely for illustrative purposes and has no intention to limit.In different embodiments, UE number
Mesh and involved process and action etc. can be different.
In addition, embodiment of the disclosure is not limited to a resource pool.On the contrary, in certain embodiments, it is one or more
Vehicle-mounted UE can be to the respective estimation congestion level in different resource pond in first terminal equipment 120-1 report areas.So, net
Network equipment 110 can determine the congestion level of multiple resource pools.
In addition, in certain embodiments, if it is determined that the resource pool in a region is excessively crowded and needs more moneys
During source, the network equipment 110 can configure the terminal device report congestion levels in other regions (for example, close region), even if
Do not overload (congestion level is not greater than threshold value) in those regions.Congestion level based on these other regions, the network equipment 110
The available resources in cell can be redistributed by adjusting the resource pool for region.
Hereinafter with reference to Fig. 3 to Fig. 5 respectively from base station 110, UE1 120-1 (vehicle-mounted UE) and UE2 120-2 (pedestrian UE)
Angle the principle and specific embodiment of the disclosure are described in detail.With reference first to Fig. 3, it is from the angle of the network equipment 110
Show the flow chart of jamming control method 300 in certain embodiments.It should be appreciated that method 300 is in the cell
It is implemented in the case of being divided multiple regions as described above.
As illustrated, at step 302, the network equipment 110 is based on preassigned and from the cell positioned at the network equipment 110
In a region in multiple terminal devices in select first terminal equipment 120-1 so as to receive congestion level report.For example,
It can select only to receive congestion from the first terminal equipment 120-1 connected with wireless heterogeneous networks (RRC) in the network equipment 110
Level report.So, only that or which selected first terminal equipment 120-1 are needed when meeting condition to network
Equipment 110 sends congestion level report.
It should be appreciated that the network equipment 110 can be with simultaneous selection other-end equipment such as third terminal equipment 120-3
To receive congestion level report.Reported by the terminal device for selecting only to specify to send congestion level, can save and send out
Foundation connects required signaling consumption between sending the terminal device and the network equipment 110 of congestion level report.
It should be appreciated that it is necessary that step 302, which is not, thus it is shown in broken lines in figure.For example, only existed when in region
One can send congestion level report terminal device when, or wish can be with from all in region when the network equipment 110
When sending the terminal device of congestion level report and receiving congestion level report, the network equipment 110 can need not select specific the
One terminal device 120-1 receives congestion level information.And for example, what a or multiple terminal devices can also be determined in advance to send out
Congestion level is sent to report.In these cases, action 302 can omit.
At step 304, the network equipment 110 receives the report of the first congestion level from the first terminal equipment 120-1 of selection,
It is that the report instruction of first congestion level is determined from the first terminal equipment 120-1 selected, from the network equipment 110 to region designation
First estimation congestion level of resource pool.
In some embodiments it is possible to understand, the resource pool in the configuring area of the network equipment 110 refers to region in other words
After sending resource pool, first terminal equipment 120-1 transmits traveling packet by resource pool.Traveling packet can indicate this
At least some information in the information such as first terminal equipment 120-1 positional information, gait of march and direct of travel.Moreover, the
One terminal device 120-1 can receive it is in resource pool, by other first terminal equipment 120-1 and second terminal equipment 120-
The traveling packet of 2 transmission, so as to be monitored to resource pool, and as described above by scheduling assignment (scheduling
Assignment, SA) decode the first estimation congestion level for coming estimating resource pond with energy measurement.Then, first terminal equipment
The first congestion level that 120-1 sends the first estimation congestion level of instruction resource pool to the network equipment 110 is reported.
In certain embodiments, first terminal equipment 120-1 can be by first terminal equipment 120-1 and the network equipment
UU interfaces between 110, via RRC signaling and/or the control element (CE) of medium access control (MAC) to the network equipment 110
Report congestion levels.
In certain embodiments, first terminal equipment 120-1 can include region when sending the report of the first congestion level
Index, so that when the terminal device for belonging to different zones sends congestion level report to the network equipment 110 simultaneously, network
Equipment 110, which can directly be known, sends the region that the terminal device of congestion level report is located at.
In certain embodiments, if associated signaling consumption is subjected to, first terminal equipment 120-1 can also be same
When to the first of the report resource pond of the network equipment 110 the positional information (example for estimating congestion level and first terminal equipment 120-1
Such as, latitude and longitude).Positional information can provide information more more than region index, and it can be for needing such as positional operand
The other application of the application of work etc is useful.Meanwhile the network equipment 110 can be from first terminal equipment 120-1 location estimating
The region index of first terminal equipment 120-1 regions.
It should be appreciated that the presently disclosed embodiments is mainly for first terminal equipment 120-1 and second terminal equipment 120-2
The situation in shared same asset pond.In certain embodiments, the network equipment 110 can assign special to second terminal equipment 120-2
The private resource pond of the transmission of traveling packet is carried out for second terminal equipment 120-2.At this moment, first in the same area is whole
End equipment 120-1 will be required monitoring second terminal equipment 120-2 private resource pond and be that second terminal equipment 120-2 is true
Surely it is directed to the first estimation congestion level in second terminal equipment 120-2 private resource pond.
Similarly, when the first terminal equipment 120-1 in the same area and second terminal equipment 120-2 shares same asset
Chi Shi, the traveling packet by first terminal equipment 120-1 and second terminal equipment 120-2 transmission can also be made a distinction,
For example, Packet type can be indicated in traveling packet or SA, so that first terminal equipment 120-1 can estimate to be directed to
Individually the first estimation congestion level as caused by the traveling packet of second terminal equipment 120-2 transmission.Because first terminal is set
Standby 120-1 can be with the congestion level of direct estimation resource pool, therefore, when first terminal equipment 120-1 determines that resource pool has occurred
During congestion situation, it can adjust the configured transmission of itself for congestion control purpose, including transimission power, the number of repeating transmission
With transmission cycle etc..
With continued reference to Fig. 3, at optional step 306, the network equipment 110 from positioned at the region at least one 3rd
Terminal device 120-3 receives the report of the second congestion level, and the report instruction of the second congestion level is determined by third terminal equipment 120-3
Resource pool second estimation congestion level.Thus, the network equipment 110 can receive from another terminal device in the same area
Estimate congestion level report for further operation.It should be appreciated that the network equipment 110 can also be from the same area more
Multi-terminal equipment receives estimation congestion level report, will not be repeated here.Certainly, the network equipment 110 can be only from first terminal
Equipment 120-1 receives the report of the first congestion level, and step 306 can be omitted in this case.
At step 308, the network equipment 110 is based at least partially on the indicated estimation of the congestion level report received
Congestion level determines the congestion level of resource pool.Due to such as error in terminal device itself and network service, delay
Etc. factor, the estimation congestion level indicated by congestion level report received from different terminal equipment might not be identical.Cause
This, the estimation congestion level that terminal device provides is also not necessarily identical with the congestion level of reality.In certain embodiments, network
Equipment 110 can be by such as increasing or decreasing the margin of error and being averaging (for receiving two or more congestion water
The situation of flat report) etc. mode resource pool determined based on the indicated estimation congestion level of the congestion level report received
Congestion level.
In certain embodiments, the network equipment 110 it is determined that resource pool congestion level when, can also for example consider
The congestion level report and the position of each terminal device that different terminal equipment in the same area is sent, so as to more
Accurately determine congestion level.Certainly, in certain embodiments, the network equipment 110 can directly select some vehicle-mounted UE and provide
Estimation congestion level, as by congestion level to be broadcast.For example, only a terminal device 120-1 it ought be set to network
When congestion level is estimated in standby 110 report, situation is such.
At step 310, the congestion level information of the broadcast instruction congestion level of the network equipment 110 is so as in region
Second terminal equipment 120-2 is received.As described above, second terminal equipment 120-2 can not be in its region for being located at of direct estimation
Resource pool congestion level.Therefore, the network equipment 110 by the form of broadcast to second terminal equipment 120-2 announcing resources
The congestion level in pond.
In certain embodiments, the network equipment 110 via system information block (SIB), by system information come to second eventually
End equipment 120-2 broadcasts congestion level information, and the congestion level information can indicate the congestion water of resource pool as described above
Flat and region index.In certain embodiments, the network equipment 110 can also be in broadcast area particular location and at these
The congestion level of opening position receives so as to the second terminal equipment 120-2 near the position.
At optional step 312, the network equipment 110 can be adjusted for second eventually based on the congestion level of resource pool
End equipment 120-2 configured transmission, and the configured transmission being adjusted is broadcasted so that second terminal equipment 120-2 is received.Can
To understand, the network equipment 110 can relatively accurately be obtained and gathered around on the estimation of the resource pool in the region in cell and cell
Fill in horizontal and the first terminal equipment 120-1 in the region in cell and cell and second terminal equipment 120-2
The information such as positional information.Moreover, the network equipment 110, which generally has, is better than first terminal equipment 120-1 and second terminal equipment
120-2 computing capability.Therefore, the network equipment 110 can calculate the transmission being adjusted for second terminal equipment 120-2
Parameter.
Similar to first terminal equipment 120-1, second terminal equipment 120-2 configured transmission can include transimission power,
The number of repeating transmission, transmission cycle, etc..The network equipment 110 is broadcasted for second terminal equipment to second terminal equipment 120-2
The 120-2 configured transmission being adjusted is received so as to second terminal equipment 120-2 and then set for changing second terminal
Standby 120-2 configured transmission.It should be appreciated that second terminal equipment 120-2 can also be by receiving the congestion level information broadcasted
Voluntarily to adjust configured transmission.Therefore, step 312 can be omitted in some cases.
At optional step 314, the network equipment 110 can adjust the configuration of the resource pool to region designation, and extensively
The configuration being adjusted is broadcast so that first terminal equipment 120-1 and second terminal equipment 120-2 is received.As described above, in network
The congestion level information that equipment 110 receives indicates that the region is excessively crowded and when needing more multiple resource, the network equipment 110 can
To redistribute the available resources in cell by adjusting the resource pool for region.Have adjusted resource pool configuration it
Afterwards, the network equipment 110 can be to the user equipment in cell (for example, first terminal equipment 120-1 and second terminal equipment 120-
2) configuration increased is adjusted in broadcast.
It should be appreciated that the configuration to resource pool be adjusted it is not necessary to.Therefore, step 314 is in some cases
It can be omitted.It should be appreciated that the execution sequence of the step of such as step 312 in method 300 and 314 etc is not to determine
's.On the contrary, no matter how or whether the sequencing of these steps is performed simultaneously, embodiment of the disclosure is not interfered with
Realize its desired technique effect.
