具体实施方式
下面将结合附图,对本申请实施例中的技术方案进行描述。
应理解,本申请实施例的技术方案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、长期演进(Long Term  Evolution,LTE)系统、LTE频分双工(Frequency Division Duplex,FDD)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)、以及未来的5G通信系统等。
本申请结合终端设备描述了各个实施例。终端设备也可以指用户设备(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。接入终端可以是蜂窝电话、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)、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,未来5G网络中的终端设备或者未来演进的陆上公用移动通信网(Public Land Mobile Network,PLMN)网络中的终端设备等。
本申请结合网络设备描述了各个实施例。网络设备可以是用于与终端设备进行通信的设备,例如,可以是GSM系统或CDMA中的基站(Base Transceiver Station,BTS),也可以是WCDMA系统中的基站(NodeB,NB),还可以是LTE系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络侧设备或未来演进的PLMN网络中的网络侧设备等。
在5G系统中,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通过数据复制的方式进行传输。
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。
可选地,数据复制传输方式的协议架构可以如图1所示。数据复制传输方式采用的是分叉承载(split bearer)的协议架构。对于上下行来说,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SCG(Secondary CG,SCG)),该CG即为锚点CG(anchor CG)。在任意一个CG中,PDCP可以将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,两个PDCP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(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,即丢弃其中一个,将另外一个递交到高层。
在NR现有的讨论中,对于配置了复制数据传输功能的无线承载,可以通过MAC控制元素(Control Element,CE)动态的激活(activate)或者去激活(de-activate)某一个承载的数据复制传输功能。
当一个媒体访问介质(Media Access Control,MAC)实体接收到上行调度资源或者获取预配置的资源时,可以开始执行(Link Control Protocol,LCP)过程,该LCP过程包括开始进行MAC PDU的生成(其中,协议数据单元(Protocol Data Unit,PDU))。每一个逻辑信道上的数据在该资源上进行传输时,传输量是由该逻辑信道的一些配置参数决定的例如优先比特速率(Priority Bit Rate,PBR),这个值决定的是LCP过程中的第一步,如果该逻辑信道能够向上行资源复用数据,其复用数据的最大值例如为该PBR与物理上行共享信道(Physical Uplink Shared Channel,PUSCH)长度(PUSCH duration)的乘积。一般来说,每个无线承载都有一个预设的数据传输速率的要求,该数据传输速率跟业务质量(Quality of Service,QoS)参数有关。在DC split bearer中,如果某个承载的数据传输速率为a,且PDCP层缓存的数据量较大,理论上该split bearer对应的两个逻辑信道的PBR为a/2即可满足要求。但是如果这个split bearer配置了数据复制功能,则数据复制传输功能激活时,由于这两个逻辑信道传输的是相同的复制数据,之前给每个逻辑信道(Logical Channel,LCH)配置的a/2的PBR就无法满足该无线承载的数据传输速率的要求。
本申请实施例提出一种数据传输的方法,当终端设备的一个无线承载的复制数据传输功能在激活(开启)状态与非激活(去激活、关闭)状态之间进行切换时,通过对该无线承载的每个逻辑信道的配置参数进行灵活调整,使得该终端设备在MAC层能够根据调整后的配置参数执行LCP过程,从而满足不同状态下的数据传输的需求。
图2是根据本申请实施例的数据传输的方法200的示意性流程图。该方法200包括以下部分内容或全部内容。
在210中,当终端设备的一个无线承载的复制数据传输功能激活或关闭时,该终端设备调整该无线承载中每个逻辑信道的配置参数。
在220中,该终端设备基于调整后的该每个逻辑信道的配置参数,执行 MAC层上的LCP过程。
具体地,当终端设备的一个无线承载的复制数据传输功能激活或关闭时,该终端设备可以对该无线承载中的至少部分逻辑信道的配置参数进行调整,其中每个逻辑信道的配置参数可以用于该逻辑信道对应的MAC层上的LCP过程例如包括MAC PDU的生成。该终端设备基于调整后的该每个逻辑信道的配置参数执行该LCP过程,从而始终能够满足该无线承载的数据传输的需求。
该配置参数例如可以为PBR,当终端设备的一个无线承载的复制数据传输功能激活或关闭时,该终端设备可以对每个逻辑信道的PBR进行调整,并使用调整后的PBR在MAC层执行LCP过程,从而能够满足该无线承载的数据传输的速率需求。
可选地,在210中,该终端设备调整该无线承载中每个逻辑信道的配置参数,包括:当该无线承载的复制数据传输功能激活时,若PDCP层上的待发送的数据量大于预设阈值,或者该PDCP层上的待发送的数据量和RLC层上待初传的数据量之和大于预设阈值,则该终端设备调整该每个逻辑信道的配置参数。
也就是说,当该无线承载的复制数据传输功能激活时,该终端设备在PDCP层上的待发送的数据量(缓存的数据量)大于预设阈值的情况下,调整该每个逻辑信道的配置参数,而该待发送的数据量小于或等于预设阈值的情况下,可以不进行配置参数的调整;或者,该终端设备在该PDCP层上的待发送的数据量和RLC层上待初传的数据量(预处理的数据量)之和大于预设阈值的情况下,调整该每个逻辑信道的配置参数,而在该待发送的数据量和该待初传的数据量之和小于或等于预设阈值的情况下,可以不进行配置参数的调整。
该预设阈值可以是网络设备为终端设备配置的,或者可以是网络设备与该终端设备事先约定的例如协议中规定并预存在该终端设备中的。
进一步地,可选地,该PDCP层上的待发送的数据量包括非复制数据的数据量,且不包括复制数据的数据量。即计算一个PDCP PDU,而不是PDCP PDU+copied PDCP PDU。
可选地,在210中,该终端设备调整该无线承载中每个逻辑信道的配置参数,包括:该终端设备在MAC层调整该每个逻辑信道的配置参数。
可选地,在210之前,该终端设备可以在MAC层接收指示信息,该指示信息用于指示该终端设备更新该每个逻辑信道的LCP参数,从而该终端设备根据该指示信息更新每个逻辑信道的该LCP参数。
进一步地,可选地,该指示信息中可以携带该配置参数的值,从而该终端设备可以将当前的配置参数的值调整为该指示信息所指示的值。
该指示信息例如可以是一个层间的交互信令,可以是该终端设备在其他协议层下发至该MAC层的一个指示。
本申请实施例提供两种方式对每个逻辑信道的配置参数进行调整。
方式1
该每个逻辑信道在复制数据传输功能关闭时所使用的配置参数为第一配置参数,该每个逻辑信道在复制数据传输功能激活时所使用的配置参数为第二配置参数。
其中,该第一配置参数为预先配置的。该第一配置参数例如可以是网络设备为终端设备配置的,或者可以是网络设备与该终端设备事先约定的例如协议中规定并预存在该终端设备中的。
其中,在210中,当该无线承载的复制数据传输功能激活时,该终端设备基于该第二配置参数与该第一配置参数之间的预设规则,根据该第一配置参数确定该第二配置参数,并将该每个逻辑信道的配置参数调整为该第二配置参数。
例如,该配置参数可以包括PBR。
例如,该预设规则可以为:该每个逻辑信道在复制数据传输功能激活时所使用的PBR,为该每个逻辑信道在复制数据传输功能关闭时所使用的PBR的两倍(后面称为规则1)。
又例如,该预设规则可以为:该每个逻辑信道在复制数据传输功能激活时所使用的PBR,为该每个逻辑信道和该无线承载中另一逻辑信道在复制数据传输功能关闭时所使用的PBR之和(后面称为规则2)。
该无线承载的复制数据传输功能激活,终端设备确定需要对每个逻辑信道的配置信息进行调整时,可以基于该预设规则,根据每个逻辑信道在复制数据传输功能关闭时所使用的PBR,确定每个逻辑信道在复制数据传输功能激活时所使用的PBR。例如,每个逻辑信道在复制数据传输功能关闭时所使用的PBR=a/2,当该无线承载的复制数据传输功能激活时,那么根据预设规 则1,终端设备可以将当前的PBR=a/2调整为PBR=a。又例如,该无线承载中的逻辑信道1在复制数据传输功能关闭时所使用的PBR=a,无线承载中的逻辑信道2在复制数据传输功能关闭时所使用的PBR=b,当该无线承载的复制数据传输功能激活时,那么根据预设规则2,终端设备可以将逻辑信道1当前使用的PBR=a调整为PBR=a+b。
方式2
该每个逻辑信道在复制数据传输功能关闭时所使用的配置参数为第一配置参数,该每个逻辑信道在复制数据传输功能激活时所使用的配置参数为第二配置参数。
其中,该第二配置参数和该第一配置参数均为预先配置的。该第二配置参数和该第一配置参数例如可以是网络设备为终端设备配置的,或者可以是网络设备与该终端设备事先约定的例如协议中规定并预存在该终端设备中的。
其中,在210中,当该无线承载的复制数据传输功能激活时,该终端设备在该第一配置参数和该第二配置参数中,选择该第二配置参数,并将该每个逻辑信道的配置参数调整为该第二配置参数。
或者,当该无线承载的复制数据传输功能关闭时,该终端设备在该第一配置参数和该第二配置参数中,选择该第一配置参数,并将该每个逻辑信道的配置参数调整为该第一配置参数。
该实施例中,由于为每个逻辑信道预先配置了两个配置参数,其中,一个是为该逻辑信道配置的专用于在该无线承载的数据复制传输功能激活时使用的配置参数,另一个是为该逻辑信道配置的专用于在该数据复制传输功能关闭时使用的配置参数。当终端设备由非激活状态切换至激活状态,则在两个配置信息中选择为激活态配置的配置参数,当终端设备由激活状态切换至非激活状态,则在两个配置信息中选择为非激活态配置的配置参数。
例如,该配置参数可以包括PBR。网络设备可以为每个逻辑信道配置两个PBR,其中一个是为激活态配置的PBR=a,另一个是为非激活态配置的PBR=a/2。该无线承载的复制数据传输功能激活时,终端设备选择PBR=a并将该逻辑信道当前的PBR由a/2调整为a;该无线承载的复制数据传输功能关闭时,该终端设备选择PBR=a/2并将该逻辑信道当前的PBR由a调整为a/2。
应理解,当该无线承载的复制数据传输功能关闭时,终端设备在PDCP层不复制PDCP PDU,该无线承载回退到split bearer的操作模式。在split bearer的操作模式中,根据PDCP规则,当PDCP层的待发送的数据量(还可以加上RLC层上待初传的数据量)大于某一个预设阈值,则数据可以在两条路径上传输。而当PDCP层的待发送的数据量(还可以加上RLC层上待初传的数据量)小于该预设阈值,则可以只在其中一条路径传输,此时,终端设备可以仅调整所使用的那条逻辑信道的配置参数例如PBR。
因此,本申请实施例中,当终端设备的一个无线承载的复制数据传输功能在激活状态与非激活状态之间进行切换时,通过对该无线承载的每个逻辑信道的配置参数进行灵活调整,使得该终端设备在MAC层能够根据调整后的配置参数执行LCP过程,从而满足不同状态下的数据传输的需求。
