具体实施方式
下面将结合附图和实施例,对本公开的具体实施方式作进一步详细描述。以下实施例用于说明本公开,但不用来限制本公开的范围。
R14 V2X PSCCH(Physical Sidelink Shared Channel,物理Sidelink共享信道)/PSSCH帧结构中,子帧的最后一个符号用作GP。
如图1所示,本公开实施例的数据传输方法,应用于作为发送端的V2X终端,包括步骤101至102。
步骤101、获取传输方式配置信息。
在本公开实施例中,发送端可获取网络侧设备发送的传输方式配置信息,或者获取系统配置的传输方式配置信息。
其中,所述传输方式配置信息可以指明哪些TTI可以连续发送,哪些业务类别(Service type)、哪些PPPP(ProSe Per-Packet Priority,直接通信数据包优先级)或者哪些QoS(Quality of Service,服务质量)可利用连续的TTI(Transmission Time Interval,传输时间间隔)传输数据。
步骤102、在所述传输方式配置信息表示需利用连续的传输时间间隔TTI进行数据传输的情况下,在同一载波上利用M个连续的TTI向接收端发送待传输数据。
其中,在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP,M为整数且M≥2。
其中,在本公开实施例中,“需利用连续的传输时间间隔TTI进行数据传输”可以有两处含义:一是,发送端必须根据传输方式配置信息规定的进行数 据传输;二是,发送端可以根据传输配置信息规定的进行数据传输。
如果是上述第一种含义,也即,在所述传输方式配置信息表示目标业务类别或目标PPPP或者目标服务质量QoS必须利用连续的TTI进行数据传输的情况下,对于目标业务类别或目标PPPP或者目标QoS的待传输数据,发送端在同一载波上利用M个连续的TTI发送待传输数据。和/或,在所述传输方式配置信息表示目标资源池必须利用连续的TTI进行数据传输的情况下,当利用所述目标资源池进行数据传输时,发送端在同一载波上利用M个连续的TTI发送待传输数据。
其中,目标业务类别,目标PPPP,或者目标QoS可任意设定。
如果是上述第二种含义,发送端还需向接收端指示其是否按照了传输配置信息进行发送。此时,发送端可向接收端发送传输方式指示信息;所述传输方式指示信息用于表示目标业务类别或目标PPPP或者目标服务质量QoS或者在目标资源池是否利用了连续的TTI进行了数据传输。
具体的,发送端可利用SA(Scheduling Assignment,调度分配)中的目标信息向接收端发送传输方式指示信息;和/或利用SA中的预留比特向接收端发送传输方式指示信息;其中,所述目标信息为用于表示作为发送端的V2X终端的传输能力的信息。
例如,假设预留比特为1,那么表示发送端根据传输方式配置信息进行了数据传输;否则表示发送端未根据传输方式配置信息进行数据传输。
在本公开实施例中,在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP,且M个TTI连续传输,从而使得一个符号上可以承载较多的数据,提高了数据的传输速率。
在上述实施例的基础上,在步骤101之前或者之后,发送端还可选择用于数据传输的连续的M个TTI。具体的,发送端获取设定的传输次数N,其中N整数,且N≥2;在候选资源中,查找满足连续M次发送的空闲TTI,并将满足M次发送的空闲TTI作为用于数据传输的连续的M个TTI;
其中,M﹤N;其中,所述M个连续的TTI具有相同或者不同的频域资源;或者对于同一V2X终端,所述M个连续的TTI对应于相同的TB(transport  block,传输块)或者不同的TB。
例如,传输次数N为3,那么,在候选资源中,从满足时延需求的候选资源集合中选择资源时,首先查找是否可以满足3次连续发送的空闲资源,如果有的话,从满足的空闲资源集合中随机选择;如果不存在满足3次连续发送的空闲资源,选择连续2次发送的空闲资源。
在上述实施例中,如果发送端本身不选择资源而是利用网络侧设备分配的资源,那么,在网络侧设备分配的资源找那个,所述M个连续的TTI具有相同或者不同的频域资源;或者对于同一V2X终端,所述M个连续的TTI对应于相同的传输块TB或者不同的TB;或者对于同一V2X终端的同一TB,优先利用连续的TTI进行数据传输。
如图2所示,本公开实施例的数据传输方法,应用于作为接收端的V2X终端,包括步骤201至203。
步骤201、接收发送端发送的数据。
步骤202、确定所述发送端是否利用了连续的TTI进行数据传输。
具体的,在此步骤中,获取网络侧设备发送的传输方式配置信息,或者,获取系统配置的传输方式配置信息,或者获取所述发送端发送的传输方式指示信息;在所述传输方式配置信息或者所述传输方式指示信息表示所述发送端利用了连续的TTI进行数据传输的情况下,确定所述发送端利用了连续的TTI进行数据传输。
在所述传输方式配置信息表示所述发送端利用了连续的TTI进行数据传输的情况下,接收端在确定所述传输方式配置信息表示目标业务或者目标业务类别或目标PPPP或者目标服务质量QoS需利用连续的TTI进行数据传输的情况下,确定所述发送端利用了连续的TTI进行数据传输;和/或在确定所述传输方式配置信息表示目标资源池需利用连续的TTI进行数据传输的情况下,确定所述发送端利用了连续的TTI进行数据传输。
当所述传输方式指示信息表示所述发送端利用了连续的TTI进行数据传输时,当SA中的目标信息为预设信息和/或所述SA中的预留比特为预设值,确定所述发送端利用了连续的TTI进行数据传输;其中,所述目标信息为用于表示发送端的传输能力的信息。其中,该预设值为终端和网络侧设备预先 约定的值。
或者,在发送端不进行任何指示的情况下,接收端还可在SA中的信息指示资源之间的时间间隔为1的情况下,对接收到的数据进行盲检;其中盲检结果包括第一盲检结果和第二盲检结果,所述第一盲检结果为假设第1个TTI至第M-1个TTI的最后一个符号进行了数据映射时的盲检结果,所述第二盲检结果为假设第1个TTI至第M-1个TTI的最后一个符号未进行数据映射时的盲检结果。然后,分别对所述第一盲检结果和第二盲检结果进行校验。在对所述第一盲检结果的校验准确的情况下,确定所述发送端利用了连续的TTI进行数据传输;在对所述第二盲检结果的校验准确的情况下,确定所述发送端未利用连续的TTI进行数据传输。
步骤203、若确定所述发送端利用了连续的TTI进行数据传输,则对所述数据中、所述发送端在同一载波上利用M个连续的TTI传输的数据进行合并处理。
其中,在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP,M为整数且M≥2。
在本公开实施例中,在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP,且M个TTI连续传输,从而使得一个符号上可以承载较多的数据,提高了数据的传输速率。
如图3所示,本公开实施例的数据传输方法,应用于网络侧设备,包括步骤301至302。
步骤301、选择用于数据传输的待分配TTI;其中,选择的待分配TTI为连续的TTI。
在此步骤中,网络侧设备获取设定的传输次数N,其中N整数,且N≥2。而后,在候选资源中,查找满足连续P次发送的空闲TTI作为待分配TTI,其中P为整数,且2≤P≤N;在选择P的过程中,优先选择使得N与选择出的P的差值最小的值。
其中,连续的TTI具有相同或者不同的频域资源;或者连续的TTI对应于相同的TB或者不同的TB。
步骤302、根据选择的待分配TTI,向终端发送传输方式配置信息,所述传输方式配置信息表示需利用连续的TTI进行数据传输。
在本公开实施例中,在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP,且M个TTI连续传输,从而使得一个符号上可以承载较多的数据,提高了数据的传输速率。
相关技术中的R14 V2X PSCCH(Physical Sidelink Shared Channel,物理Sidelink共享信道)/PSSCH帧结构中,子帧的最后一个符号用作GP,不做数据映射。考虑到R16 NR下系统带宽可能会很大,一个符号上可以承载较多的数据,同时NR对数据速率的要求更高,因此可以考虑更高效的传输模式。
因此,在本公开实施例中,对于同一个载波上,连续的M个(M为整数且M≥2)TTI同时发送。在M个连续的TTI中,第1个TTI至第M-1个TTI的最后一个符号进行了数据映射,第M个TTI的最后一个符号用作GP。图4示出了连续的2个TTI同时发送时的示意图。当多个TTI连续同时发送时,TTI连续发送的话,两个资源的时域gap为1。
在实际应用中,连续的多个TTI中,每个TTI上的频域资源不受限制,可以是相同的频域资源也可以是不同的频域资源。连续的多个TTI中,每个TTI的发送属性也不受限制,对于同一个V2X终端,可以是相同的TB,也可以是不同的TB;可以都是初传或者都是重传也可以是初传和重传。对于同一个V2X终端的同一个TB,优先保证所有的传输都连续。如果不能保证所有的传输都连续,那么,也可以是部分传输连续的;总之,其原则是尽可能保证较多次数的传输连续。
此外,在实际应用中,在集中调度方式下,本身是可以保证无碰撞,可以尽可能选择本公开实施例的连续发送方式来提高数据速率。分布式方式下,为了避免同时碰撞,尽可能保证一定的随机性,即需要在一定的随机性的基础上再考虑本公开实施例的连续发送方式。
在相关技术中,目前R14本身是存在gap=1的,即对于同一个TB不同次传输,资源连续发送必然gap=1,但是,gap=1的情况下不一定连续发送。 因此发送端可向接收端指示其是否利用了连续的TTI进行数据传输。其中,发送端的指示方法以及接收端的接收方法可归纳如下。
方式一、发送端隐含指示:
发送端从SA用户角度区分。相关技术中,SA(Scheduling Assignment,调度分配)中包含的信息主要如下:
优先级(8种):3比特。
资源预约周期索引值:4比特,用以表示资源的预约周期,也就当前SA指示的资源会在下一个预约周期时继续使用。其中资源预约周期索引值与资源预约周期的对应关系是高层信令配置的。
重传占用的频域资源位置(起点/长度):<=8比特,用于指示当前SA指示的初传和重传的数据占用的频率资源。
初传/重传的时间间隔:4比特,当只有一次传输的时候,当前比特信息位全部置为0。
调制与编码:5比特。重传指示:1比特,表示与当前SA关联的数据是初传还是重传。
预留/padding比特:>=7比特中包含的信息主要如下:
在本公开实施例中,发送端可利用SA中表示发送端传输能力的信息同时指示其是否采用了连续传输的方式。如果表示发送端传输能力的信息为约定的值,那么即可说明书发送端采用了连续传输的方式。此时,如果接收端通过传输方式等可以判定出发送端是来非R14用户,比如采用64QAM(Quadrature Amplitude Modulation,正交振幅调制),使用TxD等,那么,接收端即可认为该V2X终端采用了连续发送的方式。
方式二、发送端不指示其是否采用了连续发送的方式。
也即在此情况下发送端不指示其是否采用了连续发送的方式,而是由接收端确定发送端是否采用了连续发送的方式。
对于gap=1的TB,按照GP是否映射数据,V2X终端做两次接收和合并处理。接收端在确定gap=1时,由于它无法确定是否GP做了数据映射。因此,接收端进行盲检处理。这个时候等效于一个TB对应两个HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)接收进程,一个接收端认为没 有做数据映射,一个接收端认为做了数据映射。那么对两个盲检的结果,接收端通过CRC(Cyclic Redundancy Check,循环冗余校验)校验等确认发送端具体采用了哪一种传输方式。如果未进行GP映射的结果正确,那么即可确定GP没有做数据映射;如果进行了GP映射的结果正确,那么即可确定GP做了数据映射。
方式三:与业务绑定,或者与业务类型(service type)(目标ID),或者与PPPP绑定,或者与QoS(Quality of Service,服务质量)类别绑定。
也即,对于某种业务、某个业务类型、某个PPPP、某个QoS,通过网络侧指示或者系统配置,发送端必须或者可以采用连续的TTI传输其对应的数据。
在这种情况下,如果网络侧指示或者系统配置发送端必须采用连续的TTI传输其对应的数据,那么,此时发送端只需根据指示或者系统配置的信息,利用连续的TTI进行数据传输。也即,在这种情况下,发送端和接收端根据网络侧指示或者系统的配置已经达成了约定。对于接收端,可以根据网络侧指示或者系统配置的信息对连续TTI上传输的数据进行合并。
如果网络侧指示或者系统配置发送端可以采用连续的TTI传输其对应的数据,那么,有可能出现:(1)发送端按照网络侧指示或者系统配置采用连续的TTI传输其对应的数据;(2)发送端未按照网络侧指示或者系统配置采用连续的TTI传输其对应的数据。对于第一种情况,其处理方式和以上“网络侧指示或者系统配置发送端必须采用连续的TTI传输其对应的数据”的处理方式不同。对于第一种情况,如果发送端未按照网络侧指示或者系统配置采用连续的TTI进行传输,那么,发送端还需进一步向接收端指示其采用连续的TTI的传输情况。此时,接收端根据发送的进一步的指示对连续TTI上传输的数据进行合并。
方式四:从资源池角度区分。
在具体应用中,不同的资源池可以采用不同的传输机制,某一些资源池允许TTI连续发送,有一些资源池不允许TTI连续发送。那么,对于某个资源池是否允许TTI连续发送,可通过预配置或者SIB(System Information Block,系统信息块)21或者系统固定配置的方式确定。例如,如果发送端与R14用 户共享资源池,则不考虑连续发送;如果不是与R14用户共享资源池,则可以考虑连续发送。这种方式下,接收端可根据对应的接收资源池就可以确定gap=1的情况下是否做了数据映射。
方式五:显示指示。
在此方式下,发送端利用SA中的预留比特指示。例如,如果预留比特为1,则接收端可认为发送端采用了连续的TTI进行传输,否则可认为未采用连续的TTI进行传输。这里的连续发送可以同一TB或者不同TB的资源。
当然,以上只是举例了几种可能的指示方式,在实际应用中,并不受上述方式的限制。
以下,结合不同的应用场景描述一下本公开实施例中的资源分配方式。
应用场景一:集中分配&同一个TB初传\重传。
基站集中分配方式下,无论V2X车辆是单播、组播还是广播业务,在为某一个TB分配资源的时候,可以考虑分配连续的TTI,以用于该TB的初传以及重传。
考虑到zoning(区域)以及非逻辑子帧的存在,以及SPS(Semi-Persistent Scheduling,半持续性调度)资源分配下一些预约资源的存在,有的时候不能保证初传和所有的重传都连续,但是,可以尽可能优先分配这样的资源。
例如,在实际应用中,保证所有的或者部分传输是在连续的TTI即可。比如可以保证以下的分配方式:(1)初传+重传+xxxxx+重传;(2)初传+重传;(3)初传+重传+重传;(4)初传+xxxxx+重传+重传。第一个、第二个方式下初传和第一次重传连续发送;第三个方式下初传和所有的重传都连续发送;第四个方式下两次重传是连续发送。这里xxxxx代表的是中间未分配给用于传输该TB的TTI资源;从频域的角度来说,可以是相同的频域资源可以是不同的频域资源。
基站给V2X终端分配资源的DCI(Downlink Control Information,下行控制信息)指示相对应的资源即可,PC5 V2X终端之间只需要指示这些资源即可,具体gap=1的时候GP是否映射了数据,与具体的指示方法有关。比如,如果跟业务相关的话,gap=1的都做了数据映射。
这里的基站集中分配也可以等效替换为车队中的头车给车队内成员分配 资源。
应用场景二:集中分配&不同TB。
基站集中分配方式下,无论V2X车辆是单播、组播还是广播业务,基站分配无法满足BSR(Buffer Status Report,缓存状态报告)上报一个逻辑信道缓存的发送需求的时候;或者无法复用在同一个MAC(Media Access Control,介质访问控制)PDU(Protocol Data Unit,协议数据单元)时,例如目标ID不同或者业务大小限制,或者资源触发条件不同等条件,导致这些业务不能复用。对应不同的TB的情况下,可以考虑分配在不同的时隙资源上,例如可以考虑连续的时隙资源,即为不同的TB分配连续的TTI发送。
假定2个TB,为2个TB分配初传资源:初传1+初传2。
考虑重传的话,同样,类似应用场景一,考虑到zoning以及非逻辑子帧的存在,以及SPS资源分配下一些预约资源的存在,有的时候不能保证初传和所有的重传都连续,但是,可以尽可能优先分配这样的资源。
应用场景三:分布式&同一个载波不同TB。
车辆需要选择2个资源的时候,比如无法复用在同一个MAC PDU(比如目标ID不同或者业务大小限制,或者资源触发条件不同等条件)。此时,可以是同时选择,也可以是非同一个时间选择,但是尚存在还未来得及组包发送的grant。
比如当前缓存中有业务1,对应的资源为初传资源第5TTI,重传资源第10TTI(不对同一个TB的初传和重传做这种限制性绑定,相关技术中实现有这种方式,gap=1,非主动选择,较小概率);假设,又来了一个新的业务,需要触发资源选择,这里可以在保证随机性的基础上增加优先选择处理。
例如,尽可能保证其中一个资源与之前的某一次资源可以连续发送,比如选择2次资源的话,一次选择的时候优先选择第4TTI,第6TTI,第9TTI,第11TTI,另外一个选择按照现有实现保证随机性。
应用场景四:资源选择的角度。
无论是集中分配&同一个TB初传\重传,还是集中分配&不同TB,从选择资源的角度,从候选资源集合里选择资源的时候,尽可能选择优先初传和重传资源都连续的资源。
比如确定传输次数为3,基站分配资源的时候,从满足时延需求的候选资源集合中选择资源时,首先查找是否可以满足3次连续发送的空闲资源,如果有的话,从满足的空闲资源集合中随机选择;如果不存在满足3次连续发送的空闲资源,选择连续2次发送的空闲资源。具体可以是初传和第一次重传连续,也可以是两次重传连续。
