本申请实施例中的UE也可称为终端设备、接入终端、用户单元、用户站、移动站、移动台(mobile station,MS)、移动终端(mobile Terminal,MT)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。本申请实施例中的UE可以是指向用户提供语音和/或数据连通性的设备,可以用于连接人、物和机,例如具有无线连接功能的手持式设备、车载设备等。本申请的实施例中的UE可以是手机(mobile phone)、平板电脑(Pad)、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,虚拟现实(virtual reality,VR)设备、增强现实(augmented reality,AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(selfdriving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。可选地,UE可以用于充当基站。例如,UE可以充当调度实体,其在V2X或D2D等中的UE之间提供侧行链路信号。比如,蜂窝电话和汽车利用侧行链路信号彼此通信。蜂窝电话和智能家居设备之间通信,而无需通过基站中继通信信号。
本申请实施例中的网络设备可以是用于与UE通信的设备,该网络设备也可以称为接入网设备或无线接入网设备,如网络设备可以是基站。本申请实施例中的网络设备可以是指将UE接入到无线网络的无线接入网(radio access network,RAN)节点(或设备)。基站可以广义的覆盖如下中的各种名称,或与如下名称进行替换,比如:节点B(NodeB)、演进型基站(evolved NodeB,eNB)、下一代基站(next generation NodeB,gNB)、中继站、接入点、传输点(transmitting and receiving point,TRP)、发射点(transmitting point,TP)、主站MeNB、辅站SeNB、多制式无线(MSR)节点、家庭基站、网络控制器、接入节点、无线节点、接入点(access piont,AP)、传输节点、收发节点、基带单元(base band unit,BBU)、射频拉远单元(Remote Radio Unit,RRU)、有源天线单元(active antenna unit,AAU)、射频头(remote radio head,RRH)、中心单元(central unit,CU)、分布式单元(distributed unit,DU)、定位节点等。基站可以是宏基站、微基站、中继节点、施主节点或类似物,或其组合。

还应理解,本申请中的网络设备和UE的全部或部分功能也可以通过在硬件上运行的软件功能来实现,或者通过平台(例如云平台)上实例化的虚拟化功能来实现。
随着通信技术的发展,某些通信系统希望引入网络编码(network coding,NC)功能,以在利用更少的传输资源的情况下,提高数据传输的可靠性,从而提高传输效率。但是,目前尚不清楚如何在通信系统中实现NC功能。
为了解决上述技术问题中的一个或多个,本申请提出一种通信方法及通信装置,能够在通信系统中实现NC功能。
在本申请实施例中,为了实现NC功能,可以在现有的协议栈中加入NC层。NC层可以建立NC实体(entity),NC实体可以执行与NC相关的操作。例如,图2和图3为通信系统中协议栈的示意图,图2和图3中包括无线资源控制(radio resource control,RRC)层(图3中终端设备及网络设备侧均包括各包括2个RLC层)、分组数据汇聚协议(packet data convergence protocol,PDCP)层、无线链路控制(radio link control,RLC)层、媒体接入控制(media access control,MAC)层及物理(physical,PHY)层。需要说明的是,图2和图3示出的协议栈仅以NC层位于PDCP层与RLC层之间作为示例,在本申请实施例中,NC层也可以位于协议栈中的其他位置,本申请实施例中对此并不限定,例如,NC层也可以位于RLC层与MAC之间。或者,在图2和图3所示的协议栈中,在PDCP层之上还可 以存在服务数据适配协议(service data adaptation protocol,SDAP)层,NC层也可以位于PDCP层与SDAP层之间。
在数据包头格式中,相应地,NC包头可以位于NC层所在的两个现有协议层之间。例如,若NC层位于PDCP层与RLC层之间,则包头顺序可以为MAC,RLC,NC,PDCP,SDAP(若有);若NC层位于RLC层与MAC层之间,则包头顺序可以为MAC,NC,RLC,PDCP,SDAP(若有)。此处不一一举例。
或者,也可以在现有协议栈中的协议层内建立NC子层或NC功能或NC算法或NC实体(例如称为NC instance)。或者说,在现有协议栈中协议层内包括NC子层或NC功能或NC算法或NC实体,或者说,在现有协议实体内包括NC子层或NC功能或NC算法或NC实体。例如,图4为通信系统中协议栈的示意图,可以在PDCP层中添加NC子层或NC功能或NC算法。或者,在PDCP实体中添加NC子层或NC功能或NC算法或NC实体(instance)。或者,或者,PDCP层中的PDCP实体中建立NC实体,也就是说,可以将NC功能嵌入PDCP实体。当然,也可以在图4所示的协议栈中的其他协议层建立NC实体,本申请实施例中对此并不限定。或者,在图4所示的协议栈中,在PDCP层之上还可以存在SDAP层,NC实体也可以建立在SDAP层中。
在本申请实施例中,可以为终端设备或网络设备预先配置一种协议栈架构(例如,图2或图3所示的协议栈架构)。此时,不论NC层(或NC实体)激活或去激活,数据包在传输的过程中均需要经过NC层或NC实体。这样,不需要引入多种协议层架构,数据包传输过程中的处理相对简单。
或者,也可以为终端设备或网络设备支持或预先配置多种协议栈架构,在NC层(或NC实体)激活的情况下,使用其中的一种协议栈架构(例如,图2或图3所示的协议栈架构),在NC层(或NC实体)去激活的情况下,使用其中的另一种协议栈架构(例如,图4所示的协议栈架构)。这样,在NC层(或NC实体)去激活的情况下,数据包在传输的过程中不需要经过NC层或NC实体(在NC层(或NC实体)激活的情况下,才需要经过NC层或NC实体),从而能够提高系统的传输效率。
下面结合图5及图6对本申请实施例进行详细地举例说明。
