可选地,终端设备120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端设备,可选地,该通信系统100可以包括多个网络设备并且每个网络设备的覆盖范围内可以包括其它数量的终端设备,本申请实施例对此不做限定。
可选地,该通信系统100还可以包括网络控制器、移动管理实体等其他网络实体,本申请实施例对此不作限定。
应理解,本申请实施例中网络/系统中具有通信功能的设备可称为通信设备。以图1示出的通信系统100为例,通信设备可包括具有通信功能的网络设备110和终端设备120,网络设备110和终端设备120可以为上文所述的具体设备,此处不再赘述;通信设备还可包括通信系统100中的其他设备,例如网络控制器、移动管理实体等其他网络实体,本申请实施例中对此不做限定。
应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
下面结合图2,对本申请实施例中的DC或CA场景下的复制传输方法进行简单介绍。
在双连接(Dual Connection,DC)场景下,多个网络节点(小区组(Cell Group,CG))可以为终端设备服务,小区组和终端设备之间可以进行复制数据的传输。应理解,在本申请实施例中,CG可以等同于网络节点或网络设备等。
具体地,在DC场景下,复制传输方式的协议架构可以如图2中的DRB 2所示。分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)位于某一个CG(主CG(Master CG,MCG)或者辅CG(Secondary CG,SCG))。PDCP将PDCP协议数据单元(Protocol Data Unit,PDU)复制为相同的两份,比如一个是PDCP PDU,一个是复制(Duplicated)PDCP PDU,两份PDCP PDU经过不同CG的无线链路控制(Radio Link Control,RLC)层以及媒体接入控制(Media Access Control,MAC)层,在经过空口到达终端设备(下行)或者基站(上行)相应的MAC以及RLC层,最后再汇聚到PDCP,PDCP层监测到两个PDCP为相同的复制版本,则可以丢弃其中一个,将另外一个递交到高层。
在本申请实施例中,两份PDCP PDU经过不同CG进行传输,能够达到频率分集增益的目的,进而能够提高数据传输的可靠性。
应理解,对于配置了复制传输的承载(例如,无线承载(Data Radio Bearer,DRB)或信令无线承载(Signaling Radio Bearers,SRB)),可以通过MAC控制单元(Control Element,CE)动态的激活(activate)或者去激活(de-activate)某一个承载的复制传输功能。对于DC的情况,MCG和SCG可以分别发送MAC CE来激活或者去激活终端设备的某一个配置了复制传输的承载的复制数据功能,或者仅由MCG或SCG来发送MAC CE。
此外,在本申请实施例中,PDCP的低层用于传输复制数据的实体也可称为腿(leg或路径),或者可以用逻辑信道替换。
在CA场景下的复制传输方式的协议架构可以如图2中的DRB 1或DRB3所示。复制传输方式采用的是CA的协议架构,具体地,PDCP层生成的数据(PDU和PDU的复制数据)分别传输到两个不同的RLC实体,这两个不同的RLC实体通过相同的MAC层实体映射到不同的物理层载波。可以理解,在本申请实施例中,PDCP层所生成的数据(PDU和PDU的复制数据)分别通过两个不同的RLC实体映射到不同的物理层载波上,能够达到频率分集增益的目的,进而能够提高数据传输的可靠性。
以上,是仅支持两个RLC实体的复制传输方式。而在R16,支持至少两个RLC实体的复制传输方式,具体的,可以采用CA架构,DC架构,或者DC和CA结合的架构,进行复制传输。同样的,PDCP层所生成的数据(PDU和PDU的复制数据)分别通过至少两个不同的RLC实体映射到低层进行传输,以达到频率分集增益的目的,进而能够提高数据传输的可靠性。
但是进行复制数据的传输会增加空口资源的消耗,因此,需要一种特定的复制传输方式,能够在必要的情况下,进行复制传输,从而能够降低对资源的消耗,提升系统性能。

在确定不传输第一数据的复制数据的情况下,PDCP层删除第一数据的复制数据,或者不对该第一数据的复制数据进行处理,例如,添加PDCP头或添加RLC头,或者,不将第一数据的复制数据向低层递交,能够降低缓存该第一数据的复制数据对缓存(buffer)的占用,因此减少对PDCP层buffer的占用时间,降低对资源的消耗。
在确定不传输第一数据的复制数据的情况下,指示所述PDCP层的低层不将所述第一数据的复制数据向下递交,或者不对该第一数据的复制数据进行处理,例如添加RLC头,能够降低缓存该第一数据的复制数据对缓存(buffer)的占用,因此,可以不引入PDCP层的buffer,能够降低对资源的消耗。

又例如,所述特定单元为特定承载,且所述特定承载的复制传输去激活,所述终端设备的PDCP层可以对接收到的来自高层的数据包生成PDCP PDU,这个PDCP PDU可称为原始(original)PDCP PDU,所述PDCP层可以将该PDCP PDU进行复制,得到N个PDCP PDU,其中N大于1,PDCP层将生成的PDCP PDU的副本保存在缓存(buffer)中。进一步可以根据第一指示信息,确定是否传输这些副本,例如,若所述第一指示信息指示original PDCP PDU未传输成功,所述终端设备的PDCP层可将缓存的副本向下递交至RLC实体,进一步通过空口传输。
因此,根据本申请实施例的无线通信的方法,终端设备可以根据第一数据的传输结果,确定是否传输所述第一数据的复制数据,从而能够在需要传输所述第一数据的复制数据的情况下,传输所述第一数据的复制数据,从而提升数据传输的可靠性,或者在不需要传输所述第一数据的复制数据的情况下,不传输所述第一数据的复制数据,有利于降低对系统资源的消耗,提升系统性能。
