Description

一种通信方法及相关设备
本申请要求于2018年08月23日提交中国国家知识产权局、申请号为201810969218.6、发明名称为“一种通信方法及相关设备”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,尤其涉及一种车联网中关于数据传输的通信方法及相关设备。
背景技术
车联网V2X(vehicle to X)是智能交通运输系统的关键技术,被认为是物联网体系中最有产业潜力、市场需求最明确的领域之一,具有应用空间广、产业潜力大、社会效益强的特点,对促进汽车和信息通信产业创新发展,构建汽车和交通服务新模式新业态,推动自动驾驶技术创新和应用,提高交通效率和安全水平具有重要意义。车联网一般是指通过装载在车上的传感器、车载终端设备等提供车辆信息,实现车辆到车辆(vehicle to vehicle,V2V),车辆到基础设施(vehicle to infrastructure,V2I),车辆到网络(vehicle to Network,V2N)以及车辆到行人(vehicle to pedestrian,V2P)之间的相互通信的通信网络。
在车联网场景中,车辆之间通过V2V网络通信,可以将自身的车速、行驶方向、具体位置、是否踩了紧急刹车等信息广播给周围车辆,周围车辆的驾驶员通过获取该类信息,可以更好的感知视距外的交通状况,从而对危险状况作出提前预判进而作出避让。
一般的,在V2X场景下,终端设备和其他终端设备之间的无线直连通信接口可以称之为PC5口,基于PC5口,终端设备与其他终端设备之间进行直连通信的通信链路可以称之为侧行链路(sidelink,SL)。PC5口可以是LTE制式或者NR制式等通信系统中的PC5口。
现有机制中,侧行链路的资源配置方式一般可以有mode 3和mode 4这两种,在mode 3方式下,终端设备每次发送数据前,都需要向网络设备申请资源,然后在网络设备分配的资源上发送业务数据,则此时由于各个终端设备的资源是由网络设备统一分配的,因此一般不会发生邻近终端设备被分配到相同资源的情况,因此,mode 3方式可以保证更好的传输可靠性,但是,由于终端设备每次申请资源时,需要和网络设备之间交互信令,因此,相对于mode4方式,采用mode 3方式发送数据的传输时延相对于mode 3可能要长。在mode 4方式下,终端设备发送数据时,可以通过随机选择、基于侦听预留机制或基于部分侦听预留机制来自主地从终端设备SL传输资源池中获取侧行链路通信资源发送数据。则此时由于各个终端设备的资源是自主选择的,可以不需要和网络设备之间交互信令,所以采用mode 4方式发送数据的传输时延相对于mode 3方式可能要短,但是,由于不同终端在自主选择资源时,可能会出现不同终端设备选择相同的资源发送数据的情况,因此有可能发生传输碰撞。
目前尚没有好的机制来兼顾业务数据的传输可靠性需求和传输时延需求,也没有好的机制来合理或者均衡地使用根据两种不同资源配置方式配置的侧行链路的传输资源。
发明内容
现有机制中,终端设备一般会在根据mode 3配置的侧行链路的传输资源,或者在根据mode 4配置的侧行链路的传输资源上传输数据。例如,终端设备有根据mode 3配置的侧行链路的传输资源时,终端设备会在根据mode 3配置的侧行链路的传输资源上传输数据,但是这样则会导致根据mode 4配置的侧行链路的传输资源的利用率较低和物理下行控制信道 (Physical Uplink Shared Channel,PDCCH)的开销增大的问题。或者例如,终端设备有根据mode 4配置的侧行链路的传输资源时,终端设备会在根据mode 4配置的侧行链路的传输资源上传输数据,由于根据mode 4配置的侧行链路的传输资源是竞争性资源,相对于根据mode3配置的侧行链路的传输资源可靠性不高,所以此时又会导致有些业务的可靠性需求或者时延需求等传输需求无法得到保障。
有鉴于此,本发明实施例提供了一种通信方法及相关设备,通过本方法,可以合理或者均衡地使用根据两种不同资源配置方式的配置的侧行链路的传输资源,保障有高可靠性需求的业务数据的传输,同时实现兼顾业务数据的传输可靠性需求和传输时延。

结合第一方面的第一种可行的设计,在一种可行的设计中,该侧行链路的该资源配置方式为第一种资源配置方式和第二种资源配置方式中的至少一种,该第一终端设备基于该对应关系,在根据第一种资源配置方式和第二种资源配置方式中的至少一种配置的侧行链路的传输资源上传输该业务信息对应的数据,包括以下三种情况:

图5是本申请提供的一种通信方法的流程示意图,下面将结合图5,示例性的描述终端设备向无线接入网设备发送缓存状态报告(Buffer state report,BSR)的过程中如何才能兼顾业务数据的传输可靠性需求和传输时延。
一般性的,终端设备的业务数据可以触发缓存状态报告(buffer status report,BSR),根据所述传输资源,终端设备生成SL BSR MAC CE,该SL BSR MAC CE可以包括至少一个逻辑信道组对应的缓存数据量。通过上报SL BSR MAC CE,以便于网络设备获知终端设备的缓存信息(例如,缓存信息可以包括PDCP层和RLC层中的缓存数据量之和),从而网络设备为终端设备分配根据mode 3方式配置的侧行链路传输资源。其中,终端在上报SL BSR MAC CE的时候是按逻辑信道组进行上报的,示例性的,逻辑信道组1可以包括逻辑信道1和逻辑信道2,逻辑信道组2可以包括逻辑信道3,终端设备上报SL BSR MAC CE时,在计算逻辑信道组1的缓存数据量的时候,对应的缓存数据量可以为逻辑信道1和逻辑信道2对应的数据量之和,在计算逻辑信道组2的缓存数据量的时候,对应的缓存数据量可以为逻辑信道3对应的数据量。当网络设备接收到终端设备上报SL BSR MAC CE,可以为该终端设备分配相应大小的侧行链路的传输资源。

操作502:第一终端设备向第一无线接入网设备发送缓存状态报告。
示例性的,该第一终端设备可以基于该对应关系,向该第一无线接入网设备发送缓存状态报告,示例性的,可以包括如下:
示例性的,业务信息1和资源配置方式的对应关系可以为业务信息1对应的数据只能在根据第一种资源配置方式配置的侧行链路传输资源上传输,不能在根据第二种资源配置方式配置的侧行链路传输资源上传输。例如,第一种资源配置方式为第一无线接入网设备的第一制式的mode 3模式,这样由于第一种资源配置方式模式下需要向网络侧设备申请资源,所以业务信息1可以关联逻辑信道组,例如,业务信息1可以关联逻辑信道组1。
在这种情况下,示例性的,业务信息2和资源配置方式的对应关系可以为业务信息2对应的数据只能在根据第二种资源配置方式配置的侧行链路传输资源上传输,不能在根据第一种资源配置方式配置的侧行链路传输资源上传输;例如,第二种资源配置方式为第一无线接入网设备的第一制式的mode 4模式,这样由于第二种资源配置方式模式下不需要向网络侧设 备申请资源,所以业务信息2可以不关联任何逻辑信道组。
示例性的,业务信息3和资源配置方式的对应关系可以为操作501中的第三种情况,即业务信息3对应的数据既可以在根据第一种资源配置方式配置的侧行链路传输资源上传输,也可以在根据第二种资源配置方式配置的侧行链路传输资源上传输,例如,第一种资源配置方式为第一无线接入网设备的第一制式的mode 3模式,第二种资源配置方式为第一无线接入网设备的第一制式的mode 4模式,这时候业务信息3可以关联逻辑信道组,例如,业务信息3可以关联逻辑信道组2。
此时,示例性的,第一终端设备上报逻辑信道组1和逻辑信道组2的缓存信息给第一无线接入网设备,在计算逻辑信道组1的缓存信息时,只需要计算业务信息1对应的缓存的数据量,示例性的,假如业务信息1对应的数据的缓存数据量为100bytes,业务信息2对应的数据的缓存数据量为150bytes,业务信息3对应的数据的缓存数据量为200bytes。在计算逻辑信道组2的缓存信息时,可以包括以下任一种计算方法:

④如果业务信息3对应的数据的缓存数据量小于或等于一个阈值,此时第一无线接入网设备向第一终端设备发送第二信息,该第二信息可以包括指示信息,该指示信息用于表示在指示该业务信息对应的数据只可以在根据第二种资源配置方式配置的侧行链路的传输资源上传输,则在计算逻辑信道组2的缓存信息时可以将业务信息3对应的数据的缓存数据量视为零,为0bytes;通过本设计,示例性的有益效果包括:网络侧设备可以根据实际情况灵活指示缓存数据量小于或等于某阈值的业务数据的数据量是否计算在终端设备发送给无线接入网设备的缓存状态报告中,灵活管理缓存状态报告的开销。
⑤如果按照该比例值将该业务信息3对应的数据分为第一部分和第二部分,该第一终端设备在根据第一种资源配置方式配置的侧行链路的传输资源上传输该第一部分,该第一终端设备在根据第二种资源配置方式配置的侧行链路的传输资源上传输该第二部分,则如果该比例值为50%,则在根据第一种资源配置方式配置的侧行链路的传输资源上传输该第一部分的数据量为100bytes(200*50%=100),则此时,可以只将该第一部分关联逻辑信道组2,则逻辑信道组2的缓存信息可以为该第一部分的缓存数据量,为100bytes。通过本设计,可以根据比例值将某种业务信息对应的数据分为两个部分,示例性的有益效果包括:可以减少终端设备向无线接入网设备发送的缓存状态报告所占用的开销,减少系统信令开销,或者减少无线接入网设备根据该缓存状态报告给终端设备调度的资源,缓解系统资源紧张。
示例性的,业务信息3和资源配置方式的对应关系可以为操作501中的第三种情况,即业务信息3对应的数据既可以在根据第一种资源配置方式配置的侧行链路传输资源上传输,也可以在根据第二种资源配置方式配置的侧行链路传输资源上传输,例如,第一种资源配置方式可以为第一无线接入网设备的第一制式的mode 3模式,第二种资源配置方式可以为第二 无线接入网设备的第一制式的mode 3模式,则此时,终端设备上报缓存状态报告给网络侧设备可以包括以下任一种情况:
①如果该业务信息3对应的数据的缓存数据量大于或等于一个阈值,则可以向第一无线接入网设备发送缓存状态报告,且可以向第二无线接入网设备发送缓存状态报告;通过本设计,示例性的有益效果包括:相对于只向第一无线接入网设备发送缓存状态报告或者只向第二无线接入网设备发送缓存状态报告,当缓存数据量比较大时,比如缓存数据量大于或等于某阈值,业务数据能够更快的进行传输。②如果该业务信息3对应的数据的缓存数据量小于或等于一个阈值,此时第一无线接入网设备向第一终端设备发送第二信息,该第二信息可以包括指示信息,该指示信息用于表示在指示该业务信息3对应的数据只可以在根据第一种资源配置方式配置的侧行链路的传输资源上传输,则终端设备只可以向第一无线接入网设备发送缓存状态报告;通过本设计,示例性的有益效果包括:相对于既向第一无线接入网设备发送缓存状态报告和又向第二无线接入网设备发送缓存状态报告,可以节省系统信令开销,或者缓解系统资源紧张。
③如果该业务信息3对应的数据的缓存数据量小于或等于一个阈值,此时第一无线接入网设备向第一终端设备发送第二信息,该第二信息可以包括指示信息,该指示信息用于表示在指示该业务信息3对应的数据只可以在根据第二种资源配置方式配置的侧行链路的传输资源上传输,则此时终端设备值可以向第二无线接入网设备发送缓存状态报告。第一终端设备,第一无线接入网设备和第二无线接入网设备可以构成双连接网络架构。

示例性的,该激活重复传输的信息可以是媒体接入层控制元素(Medium access control control element,MAC CE)。
例如,当第一无线接入网设备指示该第一终端设备在根据第一种资源配置方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据和在根据第二种资源配置方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据的重复数据的时候,示例 性的,该业务信息对应的数据可以映射到两个不同的逻辑信道,该两个不同的逻辑信道可以映射到同一个MAC实体,示例性的,该两个不同的逻辑信道可以包括第一逻辑信道和第二逻辑信道,第一逻辑信道的数据可以在根据第一种资源配置方式配置的侧行链路的传输资源上进行传输,第二逻辑信道的数据可以在根据第二种资源配置方式配置的侧行链路的传输资源上进行传输。其中,第一逻辑信道和第二逻辑信道可以在哪一种资源配置方式配置的侧行链路的传输资源上进行传输的指示信息,可以是设备厂商在第一终端设备出厂前存储该指示信息的内容在第一终端设备中,或者,网络设备在第一终端设备具有网络时就可以预先配置该指示信息的内容到第一终端设备中。示例性的,该第一终端设备在存储器中存储有该指示信息的内容,该第一终端设备从存储器中读取该指示信息的内容即可。

其中,第一种资源配置方式可以是mode 3方式,第二种资源配置方式可以是mode 4方式。通过本设计,示例性的有益效果包括:可以使得终端设备均衡使用根据不同资源配置方式配置的侧行链路的传输资源。
可选的,第一种资源配置方式和第二种资源配置方式也可以是不同制式的资源配置方式,例如,第一种资源配置方式可以是LTE制式的mode 3方式,第二种资源配置方式可以是NR制式的mode 3方式。例如,第一种资源配置方式可以是LTE制式的mode 3方式,第二种资源配置方式可以是NR制式的mode 4方式。第一制式和第二制式是两种不同制式的通信系统,第一制式和第二制式的区别至少可以包括:波形参数,调制方式,带宽配置,无线帧配置方式,资源复用方式,编码方式。示例性的,第一制式系统可以是长期演进(long term evolution,LTE)移动通信系统,第二制式系统可以是第五代(5th generation,5G)移动通信系统或新无线(new radio,NR)系统;LTE制式的mode 3方式和NR的mode 3方式可以是属于同一个无线接入网设备的资源配置方式,该无线接入网设备可以是LTE的eNB基站,也可以是NR的gNB基站。一方面,终端设备区分无线接入网设备分配的资源是LTE的还是NR的方式可以有两种,一种方式是终端设备根据无线接入网设备分配LTE的资源和NR的资源的下行控制信令(downlink control information,DCI)对应的无线网络临时标识(radio network temporary identifier,RNTI)的不同来区别无线接入网设备分配的资源是LTE的还是NR的,另外一种方式是无线接入网设备为终端分配LTE的资源和NR的资源的时候共用一个DCI格式,在DCI中的预留比特位用于指示为终端设备分配的资源是LTE的,还是NR的。另一方面,无线接入网设备可以利用通过采用RNTI加扰的DCI的循环冗余码校验(cyclic redundancy check,CRC)的比特位来区分终端设备,只有具有相应的RNTI的终端设备才能准确的接收该DCI。通过本设计,示例性的有益效果包括:可以使得终端设备均衡使用根据不同制式的资源配置方式配置的侧行链路的传输资源。
可选的,第一种资源配置方式和第二种资源配置方式也可以是不同无线接入网设备配置的资源配置方式,例如,第一种资源配置方式可以为第一无线接入网设备的mode 3方式,第二种资源配置方式可以为第二无线接入网设备的mode 3方式;示例性的,上述第一终端设备,第一无线接入网设备,以及第二无线接入网设备可以构成双连接(dual-connectivity,DC)通信 架构。示例性的,双连接通信架构指的是终端设备可以同时与两个无线接入网设备存在通信连接并可收发数据。该两个无线接入网设备之中,可以有一个无线接入网设备负责与该终端设备交互无线资源控制信息,并负责和核心网控制平面实体交互,那么,该无线接入网设备可以称之为主基站(master node,MN),则另一个无线接入网设备可以称之为辅基站(secondary node,SN)。示例性的,第一无线接入网设备可以是处在双连接(dual connectivity,DC)通信架构中的主基站(master node,MN),第二无线接入网设备可以是DC通信架构中的的辅基站(secondary node,SN),或者第一无线接入网设备可以是DC情况下的SN,第二无线接入网设备可以是DC情况下的MN。通过本设计,示例性的有益效果包括:可以使得终端设备均衡使用不同无线接入网设备为终端设备配置的侧行链路的传输资源。
操作705:第一终端设备在侧行链路上进行数据的传输。
根据无线接入网设备发送的指示该第一终端设备重复传输的信息和/或激活该第一终端设备重复传输的信息,该第一终端设备在侧行链路上传输该业务信息对应的数据和/或该业务信息对应的数据的重复数据。
举例说明,第一终端设备获得的指示重复传输的信息为:指示该第一终端设备在根据mode 3方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据和在根据mode 4方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据的重复数据,此时,第一终端设备可以在根据mode 3方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据,此时,如果第一终端设备又获得了激活重复传输的信息,该激活信息为:在指示重复传输的信息可以包括指示该第一终端设备在根据mode 3方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据和在根据mode 4方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据的重复数据的情况下,激活该第一终端设备在根据mode 4方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据的重复数据,此时,该第一终端设备可以复制该业务信息对应的数据得到该业务信息对应的数据的重复数据后在根据mode 4方式配置的侧行链路的传输资源上传输该侧行链路的业务信息对应的数据的重复数据。
其中,可以在根据mode 3方式配置的侧行链路的传输资源上传输的该业务信息对应的数据可以映射在第一逻辑信道上,可以在根据mode 4方式配置的侧行链路的传输资源上传输的该业务信息对应的数据的重复数据可以映射在第二逻辑信道上。
此时,如果第一终端设备获取的侧行链路的传输资源是根据mode 3方式配置的侧行链路的传输资源,且该传输资源是该第一频率资源集合的信息,则由于可以在根据mode 3方式配置的侧行链路的传输资源上传输的该业务信息对应的数据是映射在第一逻辑信道上,所以第一终端设备可以只为第一逻辑信道分配该第一终端设备获取的根据mode 3方式配置的侧行链路的传输资源。
通过本设计,在无线接入网设备激活了第一终端设备进行重复传输的情况下,如果此时第一终端设备只获取了根据某一种资源配置方式配置的侧行链路的传输资源,可以先传输和该资源配置方式对应的业务信息对应的数据或者业务信息对应的数据的重复数据,也就是终端设备可以先为该业务信息对应的数据所映射的逻辑信道分配终端设备获得的侧行链路的传输资源。示例性的有益效果:可以在激活第一终端设备重复传输后,灵活有效地为该业务信息对应的数据或者该业务信息对应的数据的重复数据配置侧行链路的传输资源。
示例性的,图7中的第一终端设备或第二终端设备可以是车辆设备,第一无线接入网设备或第二无线接入网设备可以是LTE制式的eNB基站,可以是NR制式的gNB基站,可以 是双连接通信架构下的主基站,可以是双连接通信架构下的辅基站。
