When continuous TTI, which is utilized, in the transmission mode instruction information expression transmitting terminal carries out data transmission, when Target information in SA is that the reserved bit in presupposed information and/or the SA is preset value, determines that the transmitting terminal is utilized Continuous TTI carries out data transmission；Wherein, the target information is the information for indicating the transmittability of transmitting terminal.Wherein, The preset value is terminal and the value that network side equipment is made an appointment.
Alternatively, in the case where transmitting terminal is without any instruction, receiving end can also the information in SA indicate resource it Between time interval be 1 in the case where, blind examination is carried out to the data that receive；Wherein blind examination result include the first blind examination result and Second blind examination is as a result, the first blind examination result is to assume that the last symbol of the 1st TTI to the M-1 TTI are counted According to mapping when blind examination as a result, the second blind examination result be hypothesis the 1st TTI to the M-1 TTI last symbol not Carry out blind examination result when data mapping.Then, the first blind examination result and the second blind examination result are verified respectively.? To in the accurate situation of verification of the first blind examination result, determining that the transmitting terminal is utilized continuous TTI and carries out data biography It is defeated；In the accurate situation of verification to the second blind examination result, determine that the transmitting terminal is not counted using continuous TTI According to transmission.
Step 203, if it is determined that continuous TTI is utilized in the transmitting terminal carries out data transmission, then in the data, institute It states transmitting terminal and merges processing using the data of M continuous TTI transmission on same carrier wave.
Wherein, in M continuous TTI, the last symbol of the 1st TTI to the M-1 TTI has carried out data and has reflected It penetrates, the last symbol of m-th TTI is used as GP, and M is integer and M >=2.
In embodiments of the present invention, in M continuous TTI, the last symbol of the 1st TTI to the M-1 TTI Data mapping is carried out, the last symbol of m-th TTI is used as GP, and M TTI is continuously transmitted, so that a symbol On can carry more data, improve the transmission rate of data.
As shown in figure 3, the data transmission method of the embodiment of the present invention, is applied to network side equipment, comprising:
The TTI to be allocated of step 301, selection for data transmission；Wherein, the TTI to be allocated selected is continuous TTI.
In this step, network side equipment obtains the number of transmissions N of setting, wherein N integer, and N >=2.Then, in candidate It in resource, searches and meets idle TTI that continuous P time is sent as TTI to be allocated, wherein P is integer, and 2≤P≤N；It is selecting It is preferential to select the smallest value of difference so that N and the P selected during P.
Wherein, continuous TTI has same or different frequency domain resource；Or continuous TTI corresponds to identical TB Or different TB.
Step 302, the TTI to be allocated according to selection send transmission mode configuration information to terminal, and the transmission mode is matched Confidence breath indicates to carry out data transmission using continuous TTI.
In embodiments of the present invention, in M continuous TTI, the last symbol of the 1st TTI to the M-1 TTI Data mapping is carried out, the last symbol of m-th TTI is used as GP, and M TTI is continuously transmitted, so that a symbol On can carry more data, improve the transmission rate of data.
(Physical Sidelink Shared Channel, physics Sidelink are shared by existing R14 V2X PSCCH Channel) in/PSSCH frame structure, the last symbol of subframe is used as GP, does not do data mapping.In view of system band under R16NR Width may be very big, more data can be carried on a symbol, while requirement of the NR to data rate is higher, therefore can be with Consider more efficient transmission mode.
Therefore, in embodiments of the present invention, on the same carrier wave, continuous M (M is integer and M >=2) TTI are same When send.In M continuous TTI, the last symbol of the 1st TTI to the M-1 TTI has carried out data mapping, M The last symbol of a TTI is used as GP.Schematic diagram when Fig. 4 shows continuous 2 TTI while sending.When multiple TTI connect When continuing while sending, if TTI is continuously transmitted, the time domain gap of two resources is 1.
In practical applications, in continuous multiple TTI, the frequency domain resource on each TTI is unrestricted, can be identical Frequency domain resource is also possible to different frequency domain resources.In continuous multiple TTI, the transmission attribute of each TTI is also unrestricted, right In the same V2X terminal, identical TB can be, be also possible to different TB；Can just pass or is all that retransmit can also To be just to pass and retransmit.For the same TB of the same V2X terminal, preferentially guarantee that all transmission are all continuous.If cannot Guarantee that all transmission are all continuous, then, it is continuous to be also possible to fractional transmission；In short, its principle be guarantee as far as possible it is more The transmission of number is continuous.
In addition, in practical applications, under centralized dispatching mode, being that can guarantee collisionless in itself, can selecting as far as possible That selects the embodiment of the present invention continuously transmits mode to improve data rate.Under distributed way, in order to avoid colliding simultaneously, to the greatest extent may be used It can guarantee certain randomness, that is, need to consider further that the side of continuously transmitting of the embodiment of the present invention on the basis of certain randomness Formula.
In the prior art, there are gap=1 by R14 itself at present, i.e., for the same TB, homogeneous is not transmitted, resource Inevitable gap=1 is continuously transmitted, still, is not necessarily continuously transmitted in the case where gap=1.Therefore transmitting terminal can be indicated to receiving end Whether it, which is utilized continuous TTI, carries out data transmission.Wherein, the indicating means of transmitting terminal and the method for reseptance of receiving end can It is summarized as follows.
Mode one, transmitting terminal implicit indication:
Transmitting terminal is distinguished from SA user perspective.In the prior art, SA (Scheduling Assignment, dispatching distribution) In include information it is mainly as follows:
Priority (8 kinds): 3 bits.
Resource reservation period index value: 4 bits, to indicate the reservation periods of resource, also with regard to the resource of current SA instruction It can be continued to use in next reservation periods.Wherein resource reservation period index value and the corresponding relationship in resource reservation period are High-level signaling configuration.
Retransmit the frequency domain resource position (starting point/length) occupied :≤8 bits, be used to indicate current SA instruction first biography and The frequency resource that the data of re-transmission occupy.
The time interval of first biography/re-transmission: 4 bits, when only once transmitting, current bit information bit is all set to 0。
Modulation and coding: 5 bits.Retransmission instruction: 1 bit indicates it is just to pass or retransmit with the associated data of current SA.
Reserved/padding bit: the information for including in >=7 bits is mainly as follows:
In embodiments of the present invention, transmitting terminal can indicate that it is simultaneously using the information of transmitting terminal transmittability is indicated in SA It is no by the way of continuously transmitting.It, can specification if indicating that the information of transmitting terminal transmittability is the value of agreement Transmitting terminal is by the way of continuously transmitting.At this point, if receiving end can be determined that transmitting terminal is by transmission mode etc. Non- R14 user, for example 64QAM (Quadrature Amplitude Modulation, quadrature amplitude modulation) is used, use TxD Deng, then, receiving end is i.e. it is believed that the V2X terminal is by the way of continuously transmitting.
Whether mode two, transmitting terminal do not indicate it by the way of continuously transmitting.
Namely transmitting terminal does not indicate that it whether by the way of continuously transmitting, but is determined by receiving end in the case Whether transmitting terminal is by the way of continuously transmitting.
For the TB of gap=1, data whether are mapped according to GP, V2X terminal does reception and merging treatment twice.Receiving end When determining gap=1, since it can not determine whether that GP has done data mapping.Therefore, receiving end carries out blind examination processing.This When is equivalent to corresponding two HARQ of a TB, and (Hybrid Automatic Repeat reQuest, mixed automatic retransfer are asked Ask) receiving process, a receiving end thinks not do data mapping, and a receiving end is thought to have done data mapping.So to two A blind examination as a result, receiving end by CRC (Cyclic Redundancy Check, cyclic redundancy check) verify etc. confirmations hair Sending end specifically uses any transmission mode.If the result for not carrying out GP mapping is correct, that is, it can determine that GP is not done Data mapping；If the result for having carried out GP mapping is correct, that is, it can determine that GP has done data mapping.
Mode three: it with business-binding, is perhaps tied up with type of service (service type) (Target id) or with PPPP It is fixed, or bound with QoS (Quality of Service, service quality) classification.
That is, being indicated by network side for certain business, some type of service, some PPPP, some QoS or being Under unified central planning to set, transmitting terminal must or can transmit its corresponding data using continuous TTI.
In this case, if network side instruction or system configuration transmitting terminal must transmit it using continuous TTI Corresponding data, then, transmitting terminal need to only be counted according to instruction or the information of system configuration using continuous TTI at this time According to transmission.That is, in this case, transmitting terminal and receiving end have been reached according to network side instruction or the configuration of system Agreement.For receiving end, it can be indicated according to network side or the information of system configuration carries out the data transmitted on continuous T TI Merge.
If network side instruction or system configuration transmitting terminal can transmit its corresponding data using continuous TTI, that , it is possible to occur: (1) transmitting terminal transmits its corresponding number using continuous TTI according to network side instruction or system configuration According to；(2) transmitting terminal does not transmit its corresponding data using continuous TTI according to network side instruction or system configuration.For A kind of situation, " network side instruction or system configuration transmitting terminal must transmit it using continuous TTI to processing mode with more than The processing mode of corresponding data " is different.For the first case, if transmitting terminal is not matched according to network side instruction or system It sets and is transmitted using continuous TTI, then, transmitting terminal also needs further to indicate that it uses the biography of continuous TTI to receiving end Defeated situation.At this point, receiving end merges the data transmitted on continuous T TI according to the further instruction of transmission.
Mode four: it is distinguished from resource pool angle.
In a particular application, different resource pools can use different transmission mechanisms, certain some resource pool allows TTI to connect Supervention is sent, and has some resource pools not allow TTI to continuously transmit.So, whether TTI is allowed to continuously transmit some resource pool, It can be by being pre-configured perhaps SIB (System Information Block system information block) 21 or system fixed configurations Mode determines.For example, if transmitting terminal and R14 user sharing resource pool, do not consider to continuously transmit；It is used if not with R14 Family shared resource pond, then it is contemplated that continuously transmitting.Under this mode, receiving end can be according to corresponding reception resource pool Data mapping whether has been done in the case where determining gap=1.
Mode five: display instruction.
In this fashion, transmitting terminal is indicated using the reserved bit in SA.For example, if reserved bit is 1, receiving end It is transmitted it is believed that transmitting terminal uses continuous TTI, otherwise it is believed that not transmitted using continuous TTI.Here Continuously transmitting can be with the resource of same TB or difference TB.
Certainly, above only to schematically illustrate several possible indicating modes, in practical applications, not by the limit of aforesaid way System.
Hereinafter, describing the resource distribution mode in the embodiment of the present invention in conjunction with different application scenarios.
Application scenarios one: the same TB of centralized distribution & just pass retransmit.
Under the centralized distribution pattern of base station, it is being some TB points that no matter V2X vehicle, which is unicast, multicast or broadcasting service, When with resource, it may be considered that continuous TTI is distributed, for the first biography of the TB and re-transmission.
Presence and SPS (Semi-Persistent in view of zoning (region) and NOT logic subframe Scheduling, semi-persistent scheduling) presence of some reserve resources under resource allocation, sometimes it cannot be guaranteed that just passing and institute Some re-transmissions are all continuous, however, it is possible to which as preferential as possible distribute such resource.
For example, in practical applications, guaranteeing that all or fractional transmission is in continuous TTI.For example it can protect Demonstrate,prove the method for salary distribution below: (1) just biography+re-transmission+xxxxx+ is retransmitted；(2) just biography+re-transmission；(3) just biography+re-transmission+re-transmission；(4) just Biography+xxxxx+ re-transmission+re-transmission.First, just pass and retransmit continuously transmit for the first time under second mode；Under third mode just It passes and all re-transmissions all continuously transmits；Retransmitting twice under 4th mode is to continuously transmit.What xxxxx was represented here is intermediate It is not yet assigned to the TTI resource for being used for transmission the TB；For the angle of frequency domain, can be identical frequency domain resource can be difference Frequency domain resource.
DCI (Downlink Control Information, Downlink Control Information) of the base station to V2X terminal distribution resource It indicates corresponding resource, only needs to indicate these resources between PC5V2X terminal, GP when specific gap=1 Whether data are had mapped, it is related with specific indicating means.For example, gap=1's has all done number if related with business According to mapping.
Here base station centralized distribution can also distribute resource to member in fleet using equivalence replacement as the head vehicle in fleet.
Application scenarios two: centralized distribution & difference TB.
Under the centralized distribution pattern of base station, no matter V2X vehicle is unicast, multicast or broadcasting service, and base station distribution can not expire When sufficient BSR (Buffer Status Report, buffer status report) reports the transmission demand an of logical channel buffer； Or it can not be multiplexed in the same MAC (Media Access Control, medium access control) PDU (Protocol Data Unit, protocol Data Unit) when, such as the items such as the different perhaps business size limitations of Target id or resource trigger condition difference Part causes these business that cannot be multiplexed.In the case where corresponding different TB, it may be considered that it distributes on different time interval resources, Such as it is contemplated that continuous time interval resource, as different TB distribute continuous TTI and send.
It is assumed that 2 TB, are that 2 TB distribution just pass resource: just passing 1+ and just pass 2.
Consider if retransmitting, equally, similar application scene one, it is contemplated that the presence of zoning and NOT logic subframe, with And under SPS resource allocation some reserve resources presence, sometimes it cannot be guaranteed that just pass and all re-transmissions it is all continuous, but It is that can preferentially distribute such resource as far as possible.
Application scenarios three: the distributed same carrier wave difference TB of &.
When vehicle needs to select 2 resources, for example it can not be multiplexed that (for example Target id is different in the same MAC PDU Perhaps the limitation of business size or resource trigger condition not equal conditions).At this point it is possible to be simultaneous selection, it is also possible to non-same One selection of time, but still have and also have not enough time to the grant that group packet is sent.
For example having business 1 in current cache, corresponding resource is just to pass resource 5TTI, and retransmission resource 10TTI is not (right This restricted binding is done in the first biography of the same TB and re-transmission, and existing realize has this mode, gap=1, non-active selection, compared with Small probability)；It is assumed that having carried out a new business again, need to trigger resource selection, it here can be on the basis of guaranteeing randomness Increase preferential selection processing.
For example, guaranteeing that one of resource can be continuously transmitted with certain first resource before as far as possible, such as selection 2 times If resource, primary selection when, preferentially selects 4TTI, 6TTI, 9TTI, 11TTI, another selection according to Existing realization guarantees randomness.
Application scenarios four: the angle of resource selection.
The either same TB of centralized distribution & just pass retransmit or centralized distribution & difference TB, from selection resource angle It spends, when resource is selected in candidate resource set, selects preferential just biography and all continuous resource of retransmission resource as far as possible.
For example determine that the number of transmissions is 3, when resource is distributed in base station, from the candidate resource set for meeting delay requirement When selecting resource, first look for whether can satisfy 3 idling-resources continuously transmitted, if any, from the free time of satisfaction It is randomly choosed in resource collection；If there is no 3 idling-resources continuously transmitted are met, the free time of continuous 2 transmissions is selected Resource.It specifically can be first pass to retransmit continuously with first time, be also possible to retransmit twice continuous.
