Optionally, this described transmission is initial transmission, and the child resource selects the starting point of window for the resource selection
The starting point of window.
Optionally, if this transmission is to repeat to transmit, the terminal, which is determined, receives NACK in object time
(Negative ACKnowledge, wrong responses instruction) feedback does not receive ACK (Acknowledged in object time
Message, response message) after feedback, determine that the son in this resource selection window for using of transmission of TB provides according to object time
Source selects window.
Wherein, the object time is that the TB of described the last time transmits the corresponding feedback moment.
That is, if the terminal determine that receiving NACK feedback in object time or in object time not receive ACK anti-
Feedback, it is determined that the last TB transmits failure.
Optionally, a maximum transmission times, terminal can be set in order to avoid continuing to repeat to transmit in the embodiment of the present invention
After determining the last TB transmission failure in object time, if the number for transmitting the TB is not up to maximum transmission times,
Then determine that this child resource transmitted in the resource selection window used of TB selects window according to the object time.
If the number for transmitting the TB reaches maximum transmission times, stop repeating to transmit the TB.
That is, the selection trigger mechanism of retransmission resource: after transmitting TB, being received on the corresponding feedback channel of the TB
NACK does not receive ACK feedback and triggers the selection of retransmission resource when being not yet more than maximum transmission times.
Optionally, the terminal of that embodiment of the invention can be according to maximum transmitted time determining some or all of in following message
Number:
Opposite vehicle speed, synchronization accuracy, congestion situation, service priority, QoS (Quality of Service, business matter
Amount), TB whether be segmentation business bag data, type of service.
QoS refers to: the QoS of the business of terminal current transmission.
Whether TB is that segmentation business bag data refers to: whether the business of terminal current transmission needs segment transmissions.
Type of service refers to: the type of service of the business of terminal current transmission.
For example setting segmentation business maximum number of times of transmission is 4 times, unsegmented business maximum number of times of transmission is 2 times.
Also such as QoS grade is divided into 8, then 1~4 high priority grade maximum number of times of transmission is 4 times, 5~8 low priorities
Grade maximum number of times of transmission is 3 times.
Also such as V2X safety service maximum number of times of transmission is 4 times, and the non-security business maximum number of times of transmission of V2X is 3 times.
It should be noted that above-mentioned example is merely illustrative, it is any that maximum transmitted time can be determined according to above- mentioned information
Several modes are all suitable for the embodiment of the present invention.
A kind of mode of possible implementation is: different maximum pass different business priority can be arranged in the embodiment of the present invention
Defeated number, if it is identical service priority, existing safety service in different V2X business, and have non-security business, so
It can also angularly consider from security level angle, unicast or broadcast, increase QoS, consider whether TB is segmentation business packet number
According to, type (unicast, multicast are still broadcasted) of business etc., thus realize identical service priority also and can be set it is different most
Big the number of transmissions.
In an implementation, the maximum transmission times of the embodiment of the present invention can be any positive integer.
Optionally, if this transmission is to repeat to transmit, terminal determines what this transmission used according to the object time
When child resource in resource selection window selects window, the embodiment of the present invention gives the side of multiple choices child resource selection window
Case is set forth below several:
Mode 1, uniform method, the maximum transmission times minimum of this method can be 2 times.
Specifically, the terminal according to maximum transmission times, determines multiple child resource choosings from the resource selection window
Select the terminal of window；
The terminal determines this biography according to the number for having transmitted the TB from the terminal of multiple child resources selection window
The terminal of the defeated child resource selection window used, and the object time+M child resource used as this transmission is selected
The starting point of window, wherein M is the number of TTI transmission time slot.
For mode 1, resource selection window can be divided equally according to maximum transmission times, obtain multiple child resource selection windows
Terminal；
Later, the terminal of resource selection window each time is determined according to current the number of transmissions, while ought be transmitted each time
Receive negative-feedback determine selection resource when, determine resource selection window start next time.
Such as just transmitting, resource selection window is [T1, T1+ (T2-T1)/M], if received in moment t1 negative
Positive feedback is fed back or is not received by, then the resource selection window retransmitted for the first time is [t1+1, T1+ (T2-T1) * 2/M].M
For maximum transmission times, T1 and T2 are the moment.
By taking Fig. 3 as an example, it is assumed that maximum transmission times are 4, M 1, are a resource selection window, root between A and E in Fig. 3
Resource selection window is divided into 4 parts according to maximum transmission times, i.e. resource selection window is divided into 4 parts by tri- points of B, C and D.
The child resource selection window transmitted for the first time is in A and B；
The child resource selection window of 2nd transmission is in B and C；
The child resource selection window of 3rd transmission is in C and D；
The child resource selection window of the 4th transmission is in D and E.
Wherein, the initial position of the child resource selection window of transmission is A point, and final position is the position of setting, position A and
In B；
If also needing to retransmit after transmitting for the first time, the terminal of the child resource selection window of the 2nd transmission is C point, starting point
It is t1+1, wherein t1 is to transmit the corresponding feedback moment for the first time.
If also needing to retransmit after the 2nd transmission, the terminal of the child resource selection window of the 3rd transmission is D point, starting point
It is t2+1, wherein t2 transmits the corresponding feedback moment for the 2nd time.
If also needing to retransmit after the 3rd transmission, the terminal of the child resource selection window of the 4th transmission is D point, starting point
It is t3+1, wherein t3 transmits the corresponding feedback moment for the 3rd time.
Mode 2, non-uniform approach,
Specifically, the Partial Window in the resource selection window is divided into N number of window by the terminal, wherein N is greater than 1
Integer, the starting point of the Partial Window is the object time, and the terminal of the Partial Window is the resource selection window
Terminal；
The child resource that the terminal of the window of foremost in N number of window is used as this transmission is selected window by the terminal
Terminal, and by the object time+M as this transmission use child resource selection window starting point, wherein M be TTI
The number of transmission time slot.
Optionally, 1 M.
In implementation, for the angle of system, very maximum probability is that smaller the number of transmissions just receives successfully, it may be considered that right
It just passes and each retransmit determines different resource selection window set.
For example dichotomy (i.e. N for 2) is used, just passing the corresponding window of resource is [T1, T1+ (T2-T1)/2], if just passed
Do not succeed, receive negative-feedback in moment t1 or be not received by positive feedback, retransmit next time corresponding window [t1+1,
t1+(T2-t1)/2]。
Optionally, terminal receives the size that the case where feeding back determines N according to system configuration or in a period of time.
It is determined according to the average transmission number in a period of time, such as in a period of time, UE is transmission 2 times with regard to passing
Defeated success, just uses dichotomy, if transmission 3 times with regard to transmission success, just using 3 point-scores.
A resource selection window between A and C in Fig. 4 A by taking Fig. 4 A as an example, it is assumed that N 2, M 1, then by A and C it
Between resource selection window be divided into 2 two windows, i.e. A to B1 is a window, and B1 to C is a window；
Then, terminal is using the A point of A to B1 this window as the starting point of the child resource selection window transmitted for the first time, terminal
Position is the position of setting, in position A and B1.
If also needing to retransmit after transmitting for the first time, need to continue to divide since the feedback moment transmitted for the first time；
As shown in Figure 4 B, it is assumed that B2 is the feedback moment transmitted for the first time, then B2 to C is divided into 2 two windows, i.e. B2 is arrived
B3 is a window, and B3 to C is a window；
Then, terminal is using the B3 point of B2 to B3 this window as the terminal of the child resource selection window of the 2nd transmission, and the 2nd
The starting point of the child resource selection window of transmission is B2+1.
If also needing to retransmit after the 2nd transmission, need to continue to divide since the feedback moment of the 2nd transmission；
As shown in Figure 4 C, it is assumed that B4 is the feedback moment of the 2nd transmission, then B4 to C is divided into 2 two windows, i.e. B4
It is a window to B5, B5 to C is a window；
Then, the terminal for the child resource selection window that terminal transmits the B5 point of B4 to B5 this window as the 3rd time, the
The starting point of the child resource selection window of 3 transmission is B4+1.
It is subsequent and so on, until transmission success or the number of transmissions reach maximum transmission times.
Optionally, it will not be further continued for transmitting after transmitting (i.e. the number of transmissions reaches maximum transmission times) due to last time,
So last time can no longer partition window when transmitting.
That is, if the number of transmissions is not up to maximum transmission times after this transmission, terminal is by the resource selection
Partial Window in window is divided into N number of window.
If the number of transmissions reaches maximum transmission times after this transmission, the terminal will be in the resource selection window
Partial Window selects window as the child resource that this transmission uses.
For example maximum transmission times are 5 times, this is the 4th transmission, then by the part window in the resource selection window
Mouth is divided into N number of window；
If this is the 5th transmission, can not partition window, directly will be by the part in the resource selection window
Window selects window as the child resource that this transmission uses.Such as in Fig. 4 C, if the 4th transmission failure, by B5 to C portion
The starting point for the child resource selection window that middle the 4th transmission feedback+1 point of moment is used as this transmission, C make as this transmission
Child resource selects the terminal of window, divides without being further continued for.
After determining the child resource selection window in the resource selection window that this transmission of TB uses, so that it may from the son
Resource selection is carried out in resource selection window.
In an implementation, a resource can be selected every time, also can choose multiple resources.
Due to co-channel interference and/or with it is interior interference it is smaller, the embodiment of the present invention can pass through sensing (perception) just
Formula, backoff procedure, RTS/CTS (Request To Send/Clear To Send, request transmission/clear to send) process etc. into
Row selection.
When selecting resource, some or all of it is referred in following alternative condition to be selected:
Condition 1,
The terminal selects the resource selected in window to be time-multiplexed for target terminal from the determining child resource
Resource, wherein the target terminal be with the terminal carry out unicast terminal and/or with the terminal in the same multicast
Terminal.
Unicast and/or multicast are needed to avoid frequency division multiplexing.It either just passes or any primary re-transmission requires
Avoid the frequency division with the resource for the business packet for needing received unicast and/or multicast.Need to guarantee that transmission is ok each time
Time-division.
Here mainly reliable reception is wanted, needs to consider the variation of channel from the point of view of reliability, need to consider same
Frequency interferes, it is also necessary to consider semiduplex influence.For unicast and multi-cast terminal, non-reception object is external object, and
For inside, need sufficiently to improve reliability.Do not consider that frequency division can improve the possibility mutually listened, such as unicast multicast under some scenes
Between member, such as the business in identical resource reservation period.
Condition 2,
The terminal selects the resource selected in window to use except terminal feedback from the determining child resource
Resource except resource.
Here feedback procedure is considered that when resource selection, the biography of the reception comprising feedback information and feedback instruction
It is defeated.I.e. resource selection when need Tx chain (transmission) the competence set feedback procedure in conjunction with terminal to determine whether
Make resource selection on some TTI.
In an implementation, the terminal can also be added in this corresponding Scheduling assistance information of transmission of TB for indicating choosing
The instruction category information of the affiliated transmission block of the resource selected.
Receiving end can be made to determine which transmission block is the data that receive belong in this way, and by the number in same transmission resource
According to making reception merging treatment.
Here for indicating that the information of the affiliated transmission block of resource selected is TB described in transmission block serial number and/or initial transmission
Resource indication information.
Transmission block serial number can be SN, and as each TB distributes a SN, and the data of identical TB carry the same SN, in this way
Which transmission block receiving end can belong to according to SN determination.
The resource indication information of TB described in initial transmission is intended to indicate that the information for the resource that initial transmission uses.If just
Begin transmission failure, the resource indication information that can carry TB described in initial transmission in corresponding SA is transmitted the 2nd time, if the 2nd biography
Defeated failure, transmits the resource indication information that TB described in initial transmission can be carried in corresponding SA the 3rd time, and so on.
Receiving end is after the SA for receiving the resource indication information containing TB described in identical initial transmission in this way, so that it may know
The resource of the corresponding data of carrying SA belongs to the same TB.
Optionally, since receiving end needs to be punched according to RV, identical RV version is used if just retransmitted, such as all
It is just passed using identical RV version using another RV version using RV0 or all re-transmissions, does not then need instruction and work as
Preceding the number of transmissions.
If just retransmitting and using different RV versions, the redundancy versions for even transmitting the same TB every time are different, then described
Current transmission number is added in the Scheduling assistance information in terminal, wherein the current transmission corresponds to the biography of presently described TB
Defeated number.
For example X is 1, if the number for having transmitted TB is 2, the number of transmissions of current TB is 3.
The corresponding relationship of the number of transmissions and RV version can be stored in advance in receiving end, for example transmits corresponding RV version 0 for the first time, the
2 transmission correspond to RV version 2, corresponding RV version 1 ... the .. of the 3rd transmission.
Receiving end can according to the number in the number of transmissions and the corresponding relationship and Scheduling assistance information of RV version in this way
To know which RV version used.
Such as the 2nd transmission, then use RV version 2.
