本申请主张在2018年8月28日在中国提交的中国专利申请号No.201810990214.6的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其涉及一种传输方法及终端设备。
背景技术
目前,长期演进(Long Term Evolution,LTE)系统可支持副链路(sidelink,或译为侧链路,SL)传输,即支持终端设备比如用户设备(User Equipment,UE)之间直接在物理层上进行数据传输。ProSe(Proximity-based services,基于近距离的服务)可提供直连发现(Direct discovery,例如UE发现周围存在可以直连的UE)和直连通信(Direct communication,例如UE与周围的UE进行数据交互)等功能。
ProSe网络架构中,UE与UE之间的通信接口称为PC5接口,UE与演进的UMTS陆地无线接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN)设备连接的接口称为Uu接口。R12中,对于Uu口的数据发送和接收、PC5口discovery的发送和接收以及PC5口Communication的发送和接收的传输优先级做了如下规定(从高到低排列):1)Uu口数据发送和接收;2)SL PC5口数据发送和接收;3)SL PC5 Discovery信号通知和监听。
R13中,为了提高discovery传输性能,引入副链路发现间隔(SL discovery gap),该副链路发现间隔专门用于discovery的发送和接收。另外,考虑到Uu口随机接入信道(Random Access Channel,RACH)的特殊性,对于Uu口的数据发送和接收、PC5口discovery的发送和接收以及PC5口Communication的发送和接收的传输优先级做出重新排序(从高到低排列):1)Uu口RACH的数据发送和接收;2)SL PC5口发现信道通知消息(在SL discovery gap周期内);3)Uu口NON-RACH数据发送;4)SL PC5口discovery 监听(在SL discovery gap周期内);5)Uu口NON-RACH数据接收;6)SL PC5数据传输和接收。
此外R13中,还引入了近距离通信数据分组优先级(ProSe Per-Packet Priority,PPPP),PPPP最大可划分8组,取值0~7。PPPP值越小,数据包传输的优先级越高,一个数据包可以对应1个或多个PPPP值,当需要确定数据包的传输优先级时可参考数据包对应的PPPP值。
未来第五代新无线(5 Generation New Radio,5G NR)系统中,为了满足业务需求,引入了一种新的业务即超高可靠性与超低时延通信(Ultra-Reliable and Low Latency Communications,URLLC)业务,可以在NR Uu口上实现传输。然而,在引入URLLC业务后,目前尚未明确如何对发生碰撞的URLLC业务与副链路传输业务进行传输。

下面将结合实施例和附图对本公开的传输方法进行说明。
参见图1所示,本公开实施例提供了一种传输方法,应用于终端设备,包括如下步骤:
步骤101:当URLLC业务与副链路传输业务发生碰撞时,按照URLLC业务和副链路传输业务的传输优先级进行传输处理。
需说明的是,该URLLC业务可选为Uu口业务,可以在Uu口(比如NR Uu口)上实现传输;该副链路传输业务可选为PC5口业务,可以在PC5口上实现传输。
可选的,该副链路传输业务可以包括如下至少一项:
副链路发现(Sidelink Discovery)传输业务和副链路通信(Sidelink Communication)传输业务。
本公开实施例的传输方法,当URLLC业务与副链路传输业务发生碰撞时,按照URLLC业务和副链路传输业务的传输优先级进行传输处理,从而可以明确如何对发生碰撞的URLLC业务与副链路传输业务进行传输,避免相应的传 输资源碰撞,进一步可以保证高优先级业务需求优先得到满足。
本公开实施例中,终端设备在选择Uu口和PC5口上传输业务的优先级时,可增加考虑URLLC业务特殊性的影响。可选的,步骤101之前,所述方法还可包括:
终端设备判断与网络设备通信的传输业务是否是URLLC业务;
而步骤101可以包括:
当与网络设备通信的传输业务是URLLC业务,且URLLC业务与副链路传输业务发生碰撞时,终端设备按照URLLC业务和副链路传输业务的传输优先级进行传输处理。
这样,可充分考虑Uu口上URLLC业务特殊性的影响,从而保证高优先级业务需求优先得到满足。
本公开实施例中,当引入URLLC业务后,可为终端设备引入一个新的无线网络临时标识(Radio Network Tempory Identity,RNTI),此新的RNTI可表示为MCS-C-RNTI,该MCS-C-RNTI可用于指示新的调制与编码策略(Modulation and Coding Scheme,MCS)表格(MCS TABLE),该新的MCS表格一般用于URLLC业务,但不限于URLLC业务。
可选的,终端设备判断与网络设备通信的传输业务是否是URLLC业务的过程可以为:
终端设备根据MCS-C-RNTI,和/或MCS表格,判断与网络设备通信的传输业务是否是URLLC业务。
其中,该MCS-C-RNTI可以用于指示与网络设备通信的传输业务是否是URLLC业务。该MCS-C-RNTI可以用于指示与网络设备通信的传输业务是否是URLLC业务。也就是说,根据MCS-C-RNTI,和/或MCS表格,可直接指示Uu口上的数据传输是否是URLLC业务。
进一步的,该MCS-C-RNTI和/或MCS表格可以由如下任意一项指示:
下行控制信息(Downlink Control Information,DCI)和公共搜索空间(common search space,CCS)
可以理解的,具体实现时,除可根据MCS-C-RNTI和/或MCS表格,直接指示Uu口上的数据传输是否是URLLC业务外,还可以先由DCI指示 MCS-C-RNTI和/或MCS表格,进而根据该MCS-C-RNTI和/或MCS表格,标识Uu口上的数据传输是否是URLLC业务;或者先由CCS定义指示MCS-C-RNTI和/或MCS表格,进而根据该MCS-C-RNTI和/或MCS表格,标识Uu口上的数据传输是否是URLLC业务。
其中,上述DCI可采用新的DCI格式或者相关技术中的DCI格式,而当采用相关技术中的DCI格式时,可以利用相关技术中的DCI的拓展字段去指示MCS-C-RNTI和/或MCS表格。
本公开实施例中,终端设备在确定URLLC业务和副链路传输业务的传输优先级时,可以简单的基于业务类型确定,也可以基于预设条件确定,分别说明如下。
可选的,当基于业务类型确定时,终端设备可以直接确定URLLC业务的传输优先级高于副链路传输业务的传输优先级。进一步的,终端设备按照URLLC业务和副链路传输业务的传输优先级进行传输处理的过程可以包括:
终端设备确定URLLC业务的传输优先级高于副链路传输业务的传输优先级,传输URLLC业务,并丢弃副链路传输业务。
这样,可优先保证URLLC业务的实现。
可以理解的,具体实现时,当确定URLLC业务的传输优先级高于副链路传输业务的传输优先级时,除了可以进行如上述的传输处理即传输URLLC业务,并丢弃副链路传输业务外,还可以进行其他方式的传输处理,比如传输URLLC业务,并缓存副链路传输业务中的数据包,以在后续时刻传输,避免信息遗漏。
可选的,当基于预设条件确定时,该预设条件可选为副链路传输业务中的数据包对应的优先级标识的值大于(或者小于)预设门限值。进一步的该预设门限值可以为网络设备配置或预配置的、协议预先约定的,或者网络设备与终端设备进行协商得到的。
比如,当副链路传输业务为副链路发现传输业务时,该预设门限值可表示为thresSL-TxPriority1;或者当副链路传输业务为副链路通信传输业务时,该预设门限值可表示为thresSL-TxPriority2;或者具体实现时,副链路发现传输业务和副链路通信传输业务可以共用一个预设门限值。
进一步的,终端设备按照URLLC业务和副链路传输业务的传输优先级进行传输处理的过程可以包括:
获取副链路传输业务中的每个数据包对应的优先级标识;
分别判断所述每个数据包对应的优先级标识是否满足预设条件;
当第一数据包的优先级标识满足所述预设条件时,确定与所述第一数据包的传输碰撞的URLLC业务的传输优先级高于所述第一数据包的传输优先级,传输所述URLLC业务,并丢弃所述第一数据包;和/或
当第二数据包的优先级标识不满足所述预设条件时,确定与所述第二数据包的传输碰撞的URLLC业务的传输优先级低于所述第二数据包的传输优先级,传输所述第二数据包,并丢弃所述URLLC业务。
需说明的是,该第一数据包可以包括一个或者多个数据包,该第二数据包可以包括一个或者多个数据包。上述每个数据包对应的优先级标识可为应用层选择,可在副链路控制信息(Sidelink Control Information,SCI)中携带。
此外具体实现时,当确定与第一数据包的传输碰撞的URLLC业务的传输优先级高于第一数据包的传输优先级时,除了可以进行如上述的传输处理即传输URLLC业务,并丢弃第一数据包外,还可以进行其他方式的传输处理,比如传输URLLC业务,并缓存第一数据包,以在后续时刻传输,避免信息遗漏。或者,当确定与第二数据包的传输碰撞的URLLC业务的传输优先级低于第二数据包的传输优先级时,除了可以进行如上述的传输处理即传输第二数据包,并丢弃URLLC业务外,还可以进行其他方式的传输处理,比如传输第二数据包,并缓存此URLLC业务中的数据包,以在后续时刻传输,避免信息遗漏。
这样,借助副链路传输业务中的每个数据包对应的优先级标识,来确定URLLC业务和副链路传输业务的传输优先级,可以分情况区分确定URLLC业务和副链路传输业务的传输优先级,从而不仅可避免传输资源碰撞,还可保证高优先级业务需求优先得到满足。
本公开实施例中,可选的,该优先级标识可包括如下至少一项:
服务质量等级标识(QoS Class Identifier,QCI);例如具体实现时, QCI的值可以设置为一个整数,且进一步的QCI的值越小,代表对应数据包的传输优先级越高,或者QCI的值大,代表对应数据包的传输优先级越高;
QCI对应的服务质量文件QoSprofile中的至少一者,即QCI对应的多个QoSprofile中的至少一个QoSprofile;
QoS流标识(QoS Flow ID,QFI);例如具体实现时,QFI的值可以设置为一个整数,且进一步的QFI的值越小,代表对应数据包的传输优先级越高,或者QFI的值越大,代表对应数据包的传输优先级越高;
PPPP;例如具体实现时,PPPP的值可以设置为一个整数,且进一步的PPPP的值越小,代表对应数据包的传输优先级越高,或者PPPP的值越大,代表对应数据包的传输优先级越高。
本公开实施例中,当利用副链路发现间隔进行副链路发现传输业务时,在进行副链路发现传输业务之前,可借助终端请求上报和网络配置,为终端设备配置所需的副链路发现间隔。具体的,当上述的副链路传输业务包括副链路发现传输业务时,步骤101之前,所述方法还可包括:
终端设备向网络设备发送请求消息(SL-GapRequest);
终端设备从网络设备接收允许终端设备使用的副链路发现间隔(sidelink discovery gap)的配置信息(SL-GapConfig)。
其中,上述终端设备发送的请求消息可以用于请求副链路发现传输业务对应的副链路发现间隔,该请求消息中可以包括如下至少一项:用于网络设备为终端设备配置副链路发现间隔时使用的间隔形式(gapPattern),和所述间隔形式所适用的载波频率(carrierFreq)。其中该载波频率可用于网络设备为终端设备配置该载波频率下的副链路发现间隔。
进一步的,所述间隔形式可以包括如下至少一项:
发现间隔偏移值(gapOffset),可表示从SFN 0开始到第一个发现间隔周期(gapPeriod)开始的偏移值;
发现间隔周期(gapPeriod),可用于指示发现间隔子帧的位图文件(gapSubframeBitmap)的周期;
发现间隔子帧的位图文件(gapSubframeBitmap),可用于指示对应的子帧是否能够用于副链路发现传输;
发现间隔符号的位图文件(gapSymbolBitmap),可用于指示对应的符号是否能够用于副链路发现传输;
发现间隔时隙的位图文件(gapSlotBitmap),可用于指示对应的时隙是否能够用于副链路发现传输;
发现间隔子时隙的位图文件(gapMini-slotBitmap),可用于指示对应的子时隙是否能够用于副链路发现传输。
进一步的,终端设备接收到的配置信息可以包括如下至少一项:
发现间隔偏移值(gapOffset),可表示从SFN 0开始到第一个发现间隔周期(gapPeriod)开始的偏移值;
发现间隔周期(gapPeriod),可用于指示发现间隔子帧的位图文件(gapSubframeBitmap)的周期;

其中借助gapSlotBitmap,可以实现基于更细粒度指示副链路发现间隔(sidelink discovery gap)。

存储器309可用于存储软件程序以及各种数据。存储器309可主要包括存储程序区和存储数据区,其中,存储程序区可存储操作系统、至少一个功能所需的应用程序(比如声音播放功能、图像播放功能等)等;存储数据区可存储根据手机的使用所创建的数据(比如音频数据、电话本等)等。此外,存储器309可以包括高速随机存取存储器,还可以包括非易失性存储器,例如至少一个磁盘存储器件、闪存器件、或其他易失性固态存储器件。
处理器310是终端设备的控制中心,利用各种接口和线路连接整个终端的各个部分,通过运行或执行存储在存储器309内的软件程序和/或模块,以及调用存储在存储器309内的数据,执行终端的各种功能和处理数据,从而对终端进行整体监控。处理器310可包括一个或多个处理单元;优选的,处理器310可集成应用处理器和调制解调处理器,其中,应用处理器主要处理操作系统、用户界面和应用程序等,调制解调处理器主要处理无线通信。可以理解的是,上述调制解调处理器也可以不集成到处理器310中。
终端设备300还可以包括给各个部件供电的电源311(比如电池),优选的,电源311可以通过电源管理系统与处理器310逻辑相连,从而通过电源管理系统实现管理充电、放电、以及功耗管理等功能。
另外,终端设备300还可包括一些未示出的功能模块,在此不再赘述。
本公开实施例还提供一种计算机可读存储介质,计算机可读存储介质上存储有计算机程序,该计算机程序被处理器执行时可实现上述传输方法实施例的各个过程,且能达到相同的技术效果,为避免重复,这里不再赘述。其中,该计算机可读存储介质,例如为只读存储器(Read-Only Memory,ROM)、随机存取存储器(Random Access Memory,RAM)、磁碟或者光盘等。
需要说明的是,在本文中,术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含,从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素,而且还包括没有明确列出的其他要素,或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下,由语句“包括一个……”限定的要素,并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素。
通过以上的实施方式的描述,本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现,当然也可以通过硬件,但很多情况下前者是更佳的实施方式。基于这样的理解,本公开的技术方案本质上或者说对相关技术做出贡献的部分可以以软件产品的形式体现出来,该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中,包括若干指令用以使得一台终端(可以是手机,计算机,服务器,空调器,或者网络设备等)执行本公开各个实施例所述的方法。
上面结合附图对本公开的实施例进行了描述,但是本公开并不局限于上述的具体实施方式,上述的具体实施方式仅仅是示意性的,而不是限制性的,本领域的普通技术人员在本公开的启示下,在不脱离本公开宗旨和权利要求所保护的范围情况下,还可做出很多形式,均属于本公开的保护之内。
