Description

传输数据的方法、终端设备和网络设备 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及传输数据的方法、终端设备和网络设备。
背景技术
终端设备向网络设备上报缓存状态报告(Buffer Status Report,BSR)是为了让网络设备获知该终端设备的待传输数据的缓存状态,以便该网络设备能够更精确的给该终端设备授权上行资源。BSR的上报是通过无线资源控制(Radio Resource Control,RRC)信令配合的参数控制的。例如,缓存状态报告周期定时器(periodicBSR-Timer),缓存状态报告重传定时器(retxBSR-Timer)等。
此外,根据业务的不同,终端设备可能建立大量的无线承载(radio bearer,每个bearer对应一个逻辑信道),如果为每一个逻辑信道上报一个BSR,会带来大量的信令开销。为了避免这种情况,引入了逻辑信道组(logical channel group,LCG)的概念,并将每个逻辑信道放入一个LCG中。终端设备基于LCG来上报BSR,而不是为每个逻辑信道上报一个BSR。例如,在长期演进(Long Term Evolution,LTE)技术中LCG的数量是4个,而在新空口(NR)技术中LCG的数量是8。
在LTE中,终端设备在只有一个LCG有待传输数据时,终端设备采用短缓存状态报告格式(short BSR)上报其缓存(buffer)状态。但是,由于NR中的长缓存状态报告格式(long BSR)为位图(bitmap)的形式,终端设备仅有一个LCG存在待传输数据时,终端设备也可以采用short BSR上报其缓存buffer状态,其中只带一个LCG。而现有技术中,并没有涉及终端设备在只有一个LCG有待传输数据时确定其BSR的上报格式的方法。
因此,针对终端设备只有一个LCG有待传输数据的情况,本领域急需提供一种确定其BSR的上报格式的方法。

具体实施方式
图1是本发明实施例的应用场景的示意图。
如图1所示,通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解,本发明实施例仅以通信系统100进行示例性说明,但本发明实施例不限定于此。也就是说,本发明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、通用分组无线业务(General Packet Radio Service,GPRS)、长期演进(Long Term Evolution,LTE)系统、LTE时分双工(Time Division Duplex,TDD)、通用移动通信系统(Universal Mobile Telecommunication System,UMTS)等。
此外,本发明结合网络设备和终端设备描述了各个实施例。
其中,网络设备120可以指网络侧的任一种用来发送或接收信号的实体。例如,可以是机器类通信(MTC)的用户设备、GSM或CDMA中的基站(Base Transceiver Station,BTS)、WCDMA中的基站(NodeB)、LTE中的演进型基站(Evolutional Node B,eNB或eNodeB)、5G网络中的基站设备等。
终端设备110可以是任意终端设备。具体地,终端设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,也可称为接入终端、用户设备(User Equipment,UE)、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。例如,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、可穿戴设备以及5G网络中的终端设备等。
图2是本发明实施例的传输数据的方法的示意性流程图。
如图2所示,该方法包括:
210,网络设备生成指示信息。
220,该网络设备向终端设备发送该指示信息。
230,该终端设备根据指示信息,确定缓冲状态报告的上报格式。
具体的,该终端设备仅有一个LCG存在待传输数据时,确定该一个LCG的BSR的上报格式,该上报格式为第一格式或第二格式,该第一格式和该第二格式不同;该终端设备根据该一个LCG的BSR的上报格式,上报该一个LCG的BSR。
需要注意的是,本发明实施例的传输数据的方法适用于终端设备仅有一个LCG存在待传输数据的场景。但不限于该场景。
例如,终端设备具有多个LCG,且该多个LCG存在待传输数据时,该终端设备可以直接将该多个LCG的上报格式确定为该第一格式或者第二格式。
应理解,本发明实施例中的术语第一格式和第二格式,仅用来将BSR的上报格式彼此区分开。本发明实施例对其具体形式不作限定。
在一个实施例中,该第一格式和该第二格式能够携带的BSR的数量不同。进一步地,该第一格式为用于只上报该一个LCG的BSR的格式,该第二格式为用于上报至少包括该一个LCG的BSR的格式。
为便于方案的理解,下面以该第一格式为short BSR,该第二格式为long BSR为例进行说明。
图3和图4示意性地给出了本发明实施例中的第一格式,图5和图6示意性地给出了本发明实施例的第二格式。
例如,如图3所示,该第一格式可以包括:一个逻辑信道组标识(LCG ID)域和一个对应的缓冲区大小(Buffer Size)域,可以看出,该第一格式只能上报一个LCG的BSR。其中,LCG ID域指定了上报的buffer状态对应的LCG,Buffer Size指定了终端设备在发送这个BSR的传输时间间隔(TTI)内的所有媒体介入控制(Media Access Control,MAC)协议数据单元(Protocol Data Unit,PDU)都生成以后,对应LCG的所有逻辑信道的无线链路层控制协议(Radio Link Control,RLC)层和分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层中剩余的可用于传输的有效数据的总和。此外,图3所示的Octl为一个比特单位,例如,如图3所示的8比特。
又例如,如图4所示,该第一格式也可以包括:两个预留(R)域和一个逻辑信道组标识(LCG ID)域。换句话说,通过两个R域指示对应LCG的所有逻辑信道的待传输数据的大小。
又例如,如图5所示,该第二格式可以包括:位图(bitmap)域和缓冲 区大小(Buffer Size)域。其中,bitmap域指示终端设备具有的所有LCG的BSR的上报情况,具体的,如图5所示的B1至B8。例如,假设bitmap域的数值为10000000,则可以理解为终端设备的上报的buffer状态仅对应一个LCG。
又例如,如图6所示,该第二格式也可以包括:两个预留(R)域和一个逻辑信道组标识(LCG ID)域。换句话说,通过两个R域指示对应LCG的所有逻辑信道的待传输数据的大小。应理解,图4所示的第一格式和图6所示的第二格式的区别可以在于:图4所示的第一格式的预留域中可以包括除LCG ID之外的信息,而图6所示的R域中可以包括LCG ID。但本发明实施例不限于此。
应理解,本发明实施例的第一格式和第二格式不限于图3至图6的示例性描述。例如,如图3所示,LCG ID域的域长为3个比特,又例如,Buffer Size域的域长为5比特。但本发明实施例不限于此。例如,LCG ID域的域长为2个比特,又例如,Buffer Size域的域长为6比特。
本发明实施例的技术方案,仅有一个逻辑信道组LCG存在待传输数据时,终端设备能够通过先确定这一个LCG的BSR的上报格式,然后根据这一个LCG的BSR的上报格式上报这一个LCG的BSR,提高BSR的上报效率。
下面对本发明实施例中仅有一个LCG存在待传输数据时,终端设备确定该一个LCG的BSR的上报格式的实现方式进行说明。
在一个实施例中,该终端设备根据该一个LCG的数据量和/或该一个LCG的对应的业务类型,确定该一个LCG的BSR。
例如,该一个LCG的待传输数据的数据量小于一个门限值时,该终端设备可以选择short BSR;如果这一个LCG的待传输数据的数据量大于该门限值时,该终端设备可以选择long BSR。
又例如,如果这一个LCG对应的业务类型为第一业务类型,则不管该LCG的待传输数据的数据量有多少,该终端设备可以选择short BSR;如果这一个LCG对应的业务类型为除该第一业务类型之外的其它业务类型,该终端设备可以选择long BSR。
又例如,如果这一个LCG对应的业务类型为第一业务类型,且,该一个LCG的待传输数据的数据量小于一个门限值时,该终端设备可以选择 short BSR;否则,该终端设备可以选择long BSR。
进一步地,该第一业务类型或者该门限值可以是预先配置的,也可以是网络设备静态或者半静态或者动态配置的。进一步地,该第一业务类型可以是视频(video)业务或者音频(voice)业务或者其他业务类型。本发明实施例不作具体限定。
下面以网络设备预配置终端设备该门限值和该第一业务类型为了进行说明。可选地,该终端设备可以接收该网络设备发送的RRC信令,该RRC信令包括该指示信息。即,网络设备可以通过RRC信令配置该门限值和该第一业务类型。
具体的,在一个实施例中,该终端设备确定该一个LCG的BSR的上报格式之前,该终端设备可以接收网络设备发送的指示信息,该指示信息用于指示在该终端设备仅有一个LCG存在待传输数据时该终端设备按照该第一格式上报该一个LCG的BSR,或者,该指示信息用于指示在该终端设备仅有一个LCG存在待传输数据时该终端设备按照该第二格式上报该一个LCG的BSR;由此,该终端设备可以根据该指示信息确定该一个LCG的BSR的上报格式。
例如,该指示信息包括门限值,该门限值用于指示:该一个LCG的待传输数据的数据量小于或等于该门限值时该终端设备按照该第一格式上报该一个LCG的BSR,该一个LCG的待传输数据的数据量大于该门限值时该终端设备按照该第二格式上报该一个LCG的BSR。
又例如,该指示信息包括第一业务类型,该第一业务类型用于指示:该一个LCG对应的业务类型为该第一业务类型时该终端设备按照该第一格式上报该一个LCG的BSR,该一个LCG对应的业务类型不是该第一业务类型时该终端设备按照该第二格式上报该一个LCG的BSR。
应理解,上述涉及的网络设备指示终端设备确定缓冲状态报告的上报格式仅为本发明实施例的示意性说明,本发明实施例不限于此。
