下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。针对本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请实施例可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,GSM)系统、码分多址(Code Division Multiple Access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)系统、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、先进的长期演进(Advanced long term evolution,LTE-A)系统、新无线(New Radio,NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum,LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum,NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、无线局域网(Wireless Local Area Networks,WLAN)、无线保真(Wireless Fidelity,WiFi)、下一代通信系统或其他通信系统等。
通常来说,传统的通信系统支持的连接数有限,也易于实现,然而,随着通信技术的发展,移动通信系统将不仅支持传统的通信,还将支持例如,设备到设备(Device to Device,D2D)通信,机器到机器(Machine to Machine,M2M)通信,机器类型通信(Machine Type Communication,MTC),以及车辆间(Vehicle to Vehicle,V2V)通信等,本申请实施例也可以应用于这些通信系统。
可选地,本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation,CA)场景,也 可以应用于双连接(Dual Connectivity,DC)场景,还可以应用于独立(Standalone,SA)布网场景。

示例性的,本申请实施例应用的通信系统100如图1所示。该通信系统100可以包括网络设备110,网络设备110可以是与终端设备120(或称为通信终端、终端)通信的设备。网络设备110可以为特定的地理区域提供通信覆盖,并且可以与位于该覆盖区域内的终端设备进行通信。

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。
本申请实施例结合终端设备和网络设备描述了各个实施例,其中:终端设备也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、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等。终端设备可以是WLAN中的站点(STAION,ST),可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统,例如,NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)网络中的终端设备等。
作为示例而非限定,在本申请实施例中,该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备,网络设备可以是WLAN中的接入点(Access Point,AP),GSM或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA中的基站(NodeB,NB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者中继站或接入点,或者车载设备、可穿戴设备以及NR网络中的网络设备或者基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中,网络设备为小区提供服务,终端设备通过该小区使用的传输资源(例如,频域资源,或者说,频谱资源)与网络设备进行通信,该小区可以是网络设备(例如基站)对应的小区,小区可以属于宏基站,也可以属于小小区(Small cell)对应的基站,这里的小小区可以包括:城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等,这些小小区具有覆盖范围小、发射功率低的特点,适用于提供高速率的数据传输服务。
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(例如,主CG(Master CG,MCG)或者辅CG(Secondary CG,SCG),也可以称为主节点(master node,MN)或辅节点(secondary node,SN))。PDCP将PDCP 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,再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,数据无线承载(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。
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(Logical Channel,LCH)替换,即RLC实体可以用leg或逻辑信道替换。相应的,RLC实体标识,可以替换为LCH标识或者leg标识。
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DRB 3所示。复制传输方式采用的是CA的协议架构,具体地,在复制传输被激活的情况下,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。
在复制传输被去激活并且满足分裂(split)传输条件的情况下,终端设备也可以使用该承载对应的两个RLC实体传输分裂数据,即通过这两个RLC实体传输不同的数据。其中,该分裂传输条件可以为这两个RLC实体的待传输的PDCP数据量和RLC数据量大于或等于预设门限。
以上,是仅支持两个RLC实体的复制传输方式。在R16中,支持至少两个RLC实体的复制传输方式,具体地,在复制传输激活的情况下,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,当复制传输去激活的情况下,可以回退到split传输。回退split传输时,可以通过无线资源控制(Radio Resource Control,RRC)指示进行split传输的secondary leg。但是,此时,primary leg和secondary leg是否能属于一个CG,如果primary leg和secondary leg属于同一个CG时如何传输,是一项亟需解决的问题。
以下详细阐述本申请针对上述技术问题而设计的分裂传输方案。
图3为本申请实施例提供的一种无线通信方法200的示意性流程图。该方法200可以由图1所示的通信系统中的终端设备执行,如图3所示,该方法200可以包括如下至少部分内容:
S210,在去激活第一承载的复制传输的情况下,终端设备根据该第一承载配置的至少三个RLC实体中的主RLC实体和辅RLC实体对应的小区组确定传输PDCP PDU的RLC实体,和/或,终端设备确定或者指示待传输的PDCP数据量。
可选地,在S210中,在去激活该第一承载的复制传输的情况下,该终端设备根据该第一承载配置的该至少三个RLC实体中的该主RLC实体和该辅RLC实体对应的小区组确定或者指示待传输的PDCP数据量。
进一步地,在S210中,在去激活该第一承载的复制传输的情况下,该终端设备根据该第一承载配置的该至少三个RLC实体中的该主RLC实体和该辅RLC实体对应的小区组确定或者指示映射该待传输的PDCP数据量的MAC实体。
具体而言,对于DC和CA结合场景下的复制传输,一个无线承载可以配置至少三个RLC实体,对应每个小区组(Cell Group,CG)配置至少一个RLC实体。该小区组例如可以是MCG和SCG。
在本申请实施例中,在去激活第一承载的复制传输的情况下,可以回退到split传输,终端设备根据该第一承载配置的至少三个RLC实体中的主RLC实体和辅RLC实体对应的小区组,确定是否进行split传输,或者,确定传输PDCP PDU的RLC实体。终端设备也可以根据该第一承载配置的至少三个RLC实体中的主RLC实体和辅RLC实体对应的小区组,确定映射待传输的PDCP数据量的MAC实体。
可选地,该至少三个RLC实体可以包括:

可选的,在本申请实施例中,RLC实体信息可以为RLC实体的标识,或者可以为标识主RLC实体或者辅RLC实体的标识位。

需要说明的是,上述图4至图7仅仅只是示例,并不对本申请实施例中的RLC实体数量和MAC实体数量构成限定,另外,RLC实体与MAC实体可以是一一对应的关系,也可以是多对一的关系,本申请实施例对此并不限定。
