Detailed description of the invention
Below with reference to accompanying drawing, various embodiments of the present invention are described in detail.
Embodiment 1: the different grouping of different priorities/business uses different access probability (mould
Formula 2)
ENB is that UE independently carries out resource selection up to 4 resource pools of configuration.So that
Prose directly communicates and supports traffic/packets priority, and eNB is the different grouping of different priorities
The access probability that/business configuration is different.Packet herein refers to this UE and directly communicates institute
Corresponding target group (ProSe Layer-2Group ID, or destination layer-2 ID).
Specifically, with reference to Fig. 1, first, in step S101, eNB passes through system message
Such as, system information block (System Information Block, SIB) broadcasts as different excellent
The different access probabilities of first level configuration.
In one example, the actual disposition situation in SIB can be as follows:
Priority list be used for indicating which/which priority level is applicable to this access probability.
Such as, SL-access probability 1==1, priority list 1 includes that a priority level is (preferential
Level 0)；SL-access probability 2==0.5, priority list 2 includes that two priority levels are (excellent
First level grade 1 and priority level 2).In this embodiment it is assumed that priority level 0 has
There is limit priority.
Then, in step s 102, for wanting to carry out the UE that ProSe directly communicates,
First it determine its priority according to traffic performance or packet characteristic, then, based on by eNB
For the different access probabilities of different priorities configuration, determine that the access corresponding to this priority is general
Rate.Such as, if UE determines that its priority is priority level 1, then determined by connect
Enter probability==0.5.
Then, in step s 103, UE selects a resource pool and determines transfer resource
Prepare immediate data transmission.Its transmission SA or Sidelink Control (SC) and
Before corresponding data in sidelink, UE between 0 to 1 according to being uniformly distributed extraction one
Individual random number, if this random number is not more than access probability, then UE can transmit sidelink
In immediate data.In this step, it is assumed that the random number that UE obtains==0.4, it is low
In access probability (0.5), it means that UE has access to PSCCH (Physical Sidelink
Control Channel, physics direct link controls channel) and PSSCH (Physical Sidelink
Shared Channel, physics direct link shares channel) transmit immediate data.
Then, in step S104, owing to UE has accessed PSCCH and PSSCH, because of
This, its determined by transmitted over resources immediate data.If UE is at current Sidelink
The immediate data of all cachings can not be transferred, then UE can continue in the Control cycle
Selection resource is for transmitting immediate data within the next Sidelink Control cycle, and nothing
Need to again be compared to guarantee business continuance by access probability and random number.Certainly, exist
In one example replaced, within each Sidelink Control cycle, UE always will access
Probability and a random number compare, if random number is not more than access probability, then UE
PSCCH and PSSCH can be accessed within the current Sidelink Control cycle；At next
In the individual Sidelink Control cycle, UE need again to extract between 0 to 1 newly with
Machine numerical value, then is compared to determine whether at this by this new random number and access probability
Sidelink carries out immediate data transmission in the Control cycle.It should be noted that other
In example, UE can also first Sidelink Control cycle utilize access probability with
Machine number compares, it is determined whether can access second Sidelink Control cycle
PSCCH and PSSCH is to transmit immediate data.It is understood that this example is shown with aforementioned
Example is substantially identical, is all to show that the result that access probability and random number compare should
For certain Sidelink Control cycle.
In this embodiment it is possible to find, once access probability==1, it means that UE is total
It is to have access to PSCCH and PSSCH to transmit immediate data.This access probability (==1)
Can be assigned to that there is limit priority.
If eNB is part priority level configures access probability, the ProSe business of user
There is the priority higher than the priority level of configuration in priority list, then be in RRC
The UE (within being in network coverage) of idle condition can set up RRC connection and ask
ENB is the immediate data transmission special resource of distribution, or UE can use priority ratio its
Any resource pool that the priority of user's ProSe business is low.If UE (is in network coverage model
Within enclosing) ProSe business have than low excellent of priority level of configuration in priority list
First level, then this UE should not carried out ProSe and directly communicate by Land use models 2, until its clothes
The configuration (i.e. the configuration of access probability) of business community amendment resource pool.
For the UE outside network coverage, it can not receive the system message that base station sends
Block, these UE can use the access probability for different priorities being pre-configured with.Work as place
When UE outside network coverage moves within network coverage, UE needs to depend on
The access probability for different priorities broadcasted by system message according to network is decided whether
Access PSCCH and PSSCH and transmit immediate data.
Embodiment 2: carry for different grouping/business for the differently configured priority in different resource pond
For different transfer resources (pattern 2)
ENB supports that ProSe directly communicates, and it independently carries out resource selection configuration resource for UE
Pond is used for carrying out immediate data transmission.
Resource selection 4 resource pools of configuration are independently carried out assuming that eNB is UE.So that
ProSe directly communicates and supports traffic/packets priority, and eNB is different resource pool configuration phase
The priority answered.
In one example, the actual disposition situation in SIB can be as follows:
Priority list be used for indicating which/which priority level is applicable to this resource pool.
Different priority lists can have different priority levels, or can have
Identical priority level.
For wanting to carry out the UE that ProSe directly communicates, its first according to traffic performance or point
Group characteristic determines its priority, then, according to determined by priority select accordingly
Resource pool transmits immediate data.If surpassed with the resource pool of same priority rank correlation connection
Cross one, then UE can select and any resource of this same priority rank correlation connection
Pond.
ENB can be that part priority level configures resource pool.Such as, due to the most enough
Available resource, eNB can be multiple high priority grade (such as, priority level 0
With priority level 1) configuration resource pool.If the ProSe business of UE has compares priority
The priority that in list, the priority level of configuration is low, then this UE should not carry out ProSe
Directly communication, until the configuration of its Serving cell amendment resource pool.
If eNB is part priority level configures resource pool, the ProSe business tool of user
There is the priority higher than the priority level of configuration in priority list, then be in RRC empty
The UE of not busy state can set up RRC connection asks eNB to be that immediate data transmission distribution is special
Resource, or UE can use the priority of its user's ProSe business of priority ratio low
Any resource pool.
Embodiment 3:eNB obtains traffic/packets priority from UE or core net, then distributes
Transfer resource transmits (pattern 1) for immediate data
The UE connected for RRC, it can ask transfer resource to be used at service eNB
The transmission of immediate data.With reference to Fig. 2, in step s 201, request message is sent as UE
During to service eNB, it can indicate that the priority of ProSe traffic/packets.In another example
In son, UE can send transmission resource request message and MAC and control signaling to eNB,
And this MAC controls to comprise in signaling the instruction of the priority for indicating ProSe traffic/packets
Information.After service eNB obtains the priority of traffic/packets, in step S202, its
It is the UE distribution transfer resource for immediate data transmission according to this priority.Such as, if
The traffic/packets priority of user is higher, then eNB can pass for this UE distribution is more
Defeated resource；And if the traffic/packets priority of user is relatively low, then eNB can be for being somebody's turn to do
UE distributes less transfer resource, or postpones resource distribution for this UE.
In another example replaced, UE can not also send the priority of traffic/packets extremely
Service eNB, but only send the type of service directly communicated or group character to servicing eNB.
After service eNB obtains type of service or group character, this service eNB asks core net
Corresponding priority is provided.After eNB obtains traffic/packets priority, it is excellent according to this
First level is the UE distribution transfer resource for immediate data transmission.
