具体实施方式
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。基于本申请中的实施例,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。
本申请实施例对应用的频谱并不限定。例如,本申请实施例可以应用于授权频谱,也可以应用于免授权频谱。
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。
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。
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(User Equipment,UE)也可以称为用户设备、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(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。
应理解,在CA场景下,支持数据复制传输(data duplication)的方案利用PDCP的复制数据功能,使复制的PDCP协议数据单元(Protocol Data Unit,PDU)分别传输到两个RLC entity(两个不同的逻辑信道),并最终保证复制的PDCP PDU能够在不同物理层聚合载波上传输,从而达到频率分集增益以提高数据传输可靠性。在DC场景下,支持数据复制传输(data duplication)的方案利用PDCP的复制数据功能,使复制的PDCP PDU分别传输到两个RLC entity,两个RLC实体分别对应不同的MAC entity。
在Rel-16中,可以采用CA和DC结合的方式实现复制数据的传输,如图2所示,对于一个PDCP服务数据单元(service data unit,SDU),在CA场景下,利用配置的PDCP复制数据功能,使CA PDCP PDU传输至RLC实体a,CA复制PDCP PDU传输至RLC实体d;在DC场景下,利用配置的PDCP复制数据功能,使DC PDCP PDU传输至RLC实体b,DC复制PDCP PDU传输至RLC实体c。进一步地,RLC实体a和RLC实体b映射至媒体接入控制(Media Access Control,MAC)实体X,RLC实体c和RLC实体d映射至MAC实体Y,MAC实体X映射至物理层载波1和物理层载波2,MAC实体Y映射至物理层载波3和物理层载波4。然而,此时若仍采用Rel-15的激活或者去激活RLC实体的方式,会造成激活时使用所有RLC的实体传输复制数据的情况,即同时使用RLC实体a、RLC实体b、RLC实体c和RLC实体d传输复制数据,实际中仅需要部分RLC实体传输复制数据,这就造成一定的资源浪费,进而降低系统性能。此外,针对承载的复制数据传输的方式,可能占用本不需要的传输资源,造成资源浪费和系统性能的降低。基于上述技术问题,本申请实施例提出了一种针对多(multiple)PDCP复制数据场景的激活去激活复制数据的方案。
需要说明的是,在上述图2中,PDCP配置的复制数据功能可以是基于数据无线承载(Data Radio Bearer,DRB)来进行配置的。
图3是根据本申请实施例的无线通信方法200的示意性流程图,该方法200可以应用于如图1所示的通信系统100,以及应用于如图2所示的CA与DC结合的场景。具体地,如图3所示,该方法200可以包括如下内容:
