Description

数据传输的方法、终端及基站 技术领域
本发明实施例涉及通信领域,并且更具体地,涉及一种数据传输的方法、终端及基站。
背景技术
设备到设备(Device-to-Device,D2D)通信也称为终端直通技术,是指邻近的终端可以在近距离范围内通过直连链路(Sidelink,SL)进行数据传输的方式。D2D通信的两个设备之间的数据传输不需要通过中心节点(即基站)进行转发。D2D技术的短距离通信特点和直接通信方式使其具有如下优势:1,终端与终端之间的近距离直接通信方式可以实现较高的数据速率、较低的延迟和较低的功耗;2,利用网络中广泛分布的用户终端以及D2D通信链路的短距离特点,可以实现频谱资源的有效利用,获得资源空分复用增益;3,D2D通信的直接通信方式能够适应如无线个人到个人(Person to Person,P2P)等业务的本地数据共享需求,提供具有灵活适应能力的数据服务;4,D2D通信能够利用网络中数量庞大且分布广泛的通信终端以拓展网络的覆盖范围。
D2D通信不仅用于公共安全业务,也可以广泛地应用于商用场景中,用以解决覆盖延伸、设备省电等现实问题。例如,蜂窝网络覆盖之外的终端可以通过作为中继的终端实现与网络的数据通信,这样一定意义上实现了网络覆盖的延伸,实现覆盖增强。并且,例如,采用D2D短距通信可以节省终端的发送功率,有利于延长终端的电池寿命。
需要注意的是,这里所指的D2D技术与传统的短距离通信技术有所不同。传统的短距离通信技术如蓝牙、无线保真直连(WiFi Direct)、Zigbee等等使用非授权频带如工业科学研究医疗(Industrial Scientific Medical,ISM)频段进行数据直接传输,与蜂窝网络形成相对独立的系统。而D2D技术是指与蜂窝系统共享使用授权频带资源的终端直通技术。
现有的D2D通信中,D2D传输资源可以是通过专用信令半静态配置的方式下发的,或者可以是由终端动态申请的方式获取的。然而,现有的方式没有考虑与终端进行D2D通信的对端终端,从而会导致配置或申请的D2D 传输资源不能保证D2D通信的成功。

具体实施方式
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例,都属于本发明保护的范围。
应理解,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)等。
还应理解,本发明实施例中,基站可以是GSM或CDMA中的基站(Base Station,BS),也可以是WCDMA中的基站(NodeB),还可以是LTE中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是未来5G网络中的基站设备等,本发明对此并不限定。基站也可以称为网络设备、网络侧装置等。
还应理解,在本发明实施例中,终端可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network)进行通信,终端可称为接入终端、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、终端设备、无线通信设备、用户代理或用户装置。终端设备可以是蜂窝电话、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、可穿戴设备以及未来5G网络中的终端设备等。
D2D通信与蜂窝系统共享使用授权频带的资源,形成统一的混合蜂窝与D2D网络。如图1所示为混合网络的示意图。在该混合网络的场景中,终端可以以两种不同的模式通信。其一,蜂窝通信模式:终端通过基站进行通信;其二,D2D模式:终端使用D2D链路直接通信。可理解,在该混合网络中,部分终端以蜂窝通信模式通过基站进行信息转发和通信,部分终端以终端直通模式进行数据的直接传输。
获取D2D的传输资源的方式可以通过专用信令半静态配置的方式或者终端动态申请的方式。如图2(a)所示为采用专用信令半静态配置的方式,图2(b)所示为终端动态申请的方式。
在图2(a)中,在终端处于连接态(connected mode)的情况下,当终端在sidelink上有数据发送或者有兴趣发送数据时,向基站发送sidelinkUEinformation消息,该消息中可以携带感兴趣的频点信息等。当基站收到终端的消息之后,会通过无线资源控制(Radio Resource Control,RRC)连接重配置(RRCconnectionconfiguration)过程为终端分配一套传输资源池和相应的传输资源配置。进一步地,终端可以在这套资源池中选择一份资源进行数据发送。
在图2(b)中,在终端处于连接态(connected mode)的情况下,当终端在sidelink上有数据发送时,发送专用调度请求(Dedicated-Scheduling Request,D-SR)或者随机接入-调度请求(Random Access-Scheduling Request,RA-SR)过程,基站通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)或者增强物理下行控制信道(enhanced PDCCH,ePDCCH)分配上行授权。终端收到上行授权之后,在物理上行共享信道(Physical Uplink Shared Channel,PUSCH)上携带直连链路缓存状态报告(SideLink-Buffer Status Reports,SL-BSR),基站根据终端上报的SL-BSR通过PDCCH或ePDCCH分配SL上数据发送的授权。
但是,随着物联网的兴起,在LTE系统中支持机器类通信(Machine Type Communication,MTC)越来越受到重视。在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)版本13(Release 13,R13)中立项了针对MTC的物理层增强项目。一台MTC终端(也称为MTC设备)可能具有多种机器与机器(Machine to Machine,M2M)通信特性之中的部分特性, 如低移动性、传输数据量小、对通信时延不敏感、要求极低功耗等特征。这里的M2M通信也属于是D2D通信。其中,为了降低MTC终端的成本,定义了一种新的终端类型,称为低成本终端,其上行和下行均只支持1.4MHz射频带宽或者更低的系统带宽,例如200KHz。然而,上述如图2(a)和图2(b)所示的D2D通信中,当发送方终端有sidelink数据待发送时,如果没有发送资源,便向基站申请资源。可是如果接收方终端是低成本终端,则基站所分配的资源有可能超出接收端的接收范围。从而会导致发送方终端与接收方终端之间的sidelink数据传输失败。
图3是本发明实施例的数据传输的方法的一个示意性流程图。图3中示出了第一终端10、第二终端20和基站30。如图4所示,第一终端10与基站30之间可以通过蜂窝链路进行通信,并且第一终端10处于网络连接态。第一终端10与第二终端20可以通过直连链路(也称为D2D链路)进行通信。
其中,第二终端20可以是低成本(low cost)终端。这里的低成本终端可以是低成本智能终端,或者可以是低成本物联网终端等,本发明对此不作限定。
一般地,低成本终端的传输带宽比普通终端的传输带宽要窄。
图3所示的方法包括:
S101,第一终端向基站发送资源配置请求,所述资源配置请求包括第二终端的设备属性信息。
可理解,第二终端的设备属性信息可以指示该第二终端为低成本终端。该第二终端的设备属性信息可以包括第二终端的接收带宽。
可理解,第一终端10处于连接态。当第一终端10需要向第二终端20发送直连链路(sidelink,SL)数据时,第一终端10可以执行S101。其中,SL数据也可以称为D2D数据。
这里,可以将第一终端10称为发送终端或发送端终端,可以将第二终端20称为接收终端或接收端终端。
其中,该第二终端的设备属性信息包括所述第二终端的接收/发送带宽。
可选地,设备属性信息还可以包括所述第二终端的接收/发送最大数据块大小。设备属性信息还可以包括所述第二终端能够同时接收的数据块大小。
可选地,设备属性信息还可以包括所述第二终端的接收/发送天线数目 等。
可选地,作为一个实施例,该资源配置请求可以携带在无线资源控制(Radio Resource Control,RRC)信令中。或者可以理解为,以RRC信令的形式发送该资源配置请求。例如,该RRC信令可以是sidelinkUEinformation信令,且该sidelinkUEinformation信令包括第二终端20的设备属性信息。如图5中的S201所示。
可选地,作为另一个实施例,该资源配置请求可以携带在媒体接入控制(Medium Access Control,MAC)协议数据单元(Protocol Data Unit,PDU)中。一般地,MAC PDU包括缓存状态报告(Buffer Status Report,BSR)。如图6中的S301所示。
可选地,可以在MAC PDU中携带特定的MAC控制单元(Control Element,CE),并由该MAC CE携带第二终端20的设备属性信息。
作为一例,MAC PDU中的BSR可以采用现有的BSR格式。并且可以通过所述MAC PDU中的逻辑信道标识(Logical Channel ID,LCID)进行标识的。例如,LCID为“010”可以表示第二终端的带宽为100kb,LCID为“011”可以表示第二终端的带宽为300kb,等等。应注意,这里对LCID的比特位数不作限定。例如,可以为3比特或5比特等。
这样,可以根据LCID确定设备属性信息。
作为另一例,可以定义新的BSR格式,并在该新定义的BSR格式中的特定字段携带第二终端20的设备属性信息。
该新定义的BSR格式可以称为低成本BSR。举例来说,可以在现有的BSR格式的基础上,增加一个字节,作为该新定义的BSR。并且该增加的一个字节可以用于指示该第二终端的设备属性信息。如图7所示,在现有的BSR格式的最后增加一个字节,且利用该增加的字节的前4比特用于指示该低成本终端,后4比特作为预留(Reserved,R)比特。也就是说,在现有的逻辑信道组(Logical Channel Group,LCG)ID为1至N的缓存之后,增加了指示低成本终端的字节。
应注意,本发明实施例中,对于新定义的BSR格式不作限定。例如,可以如图7所示是在现有的BSR格式的最后增加一个字节,或者,也可以在现有的BSR格式的最前面增加一个字节等等。
其中,该新定义的BSR格式可以由逻辑信道标识(Logical Channel ID, LCID)来指示。
举例来说,如下表一所示,可以通过索引“01011”指示使用的BSR格式为低成本BSR。
表一
Figure PCTCN2016077917-appb-000001
这样,可以根据LCID(例如为01011)确定传输的BSR的格式为图7所示的低成本BSR,进一步地,可以在该低成本BSR的最后一个字节读取设备属性信息。
S102,基站30根据资源配置请求,确定第一终端10将使用的发送资源。
具体地,基站30可以根据设备属性信息,确定第一终端10可以使用的,用于与第二终端进行D2D传输的发送资源。
具体地,设备属性信息包括第二终端20的接收带宽,基站30可以为第一终端10分配直连链路上的发送资源,并且该发送资源的物理资源块(Physical Resource Block,PRB)配置不能超过接收带宽。
可选地,作为一个实施例,若资源配置请求携带在MAC PDU中,该步骤S102可以为图6中的S302。
可选地,作为另一个实施例,若资源配置请求携带在RRC信令中,基站30可以确定第一终端10可以使用的发送资源池,该发送资源池包括所述发送资源。如图5中的S202所示。也就是说,基站30为第一终端10所配 置的是一套资源池。
S103,基站30向第一终端10发送所述发送资源配置信息。
可选地,作为一个实施例,若资源配置请求携带在MAC PDU中,该步骤S103可以为图6中的S303。其中,基站30可以通过PDCCH或ePDCCH向第一终端10发送该发送资源配置信息。
可选地,作为另一个实施例,若资源配置请求携带在RRC信令中,该步骤S103可以为图5中的S203。其中,基站30可以通过RRC连接重配置过程进行发送。
S104,第一终端10使用该发送资源,向第二终端20发送D2D数据。
其中,D2D数据也称为SL数据,可以包括多个数据块。
具体地,第一终端10可以确定发送的数据块的大小,并通过与第二终端20之间的D2D链路,向第二终端20发送该数据块。
举例来说,第一终端10可以根据发送资源的PRB配置,确定发送的数据块的大小。举例来说,第一终端10可以根据发送资源的PRB配置以及第二终端20的最大接收数据块大小,确定发送的数据块的大小。
可理解,第一终端10所确定的数据块的大小应小于第二终端20的最大接收数据块大小。
可选地,作为一个实施例,若资源配置请求携带在MAC PDU中,该步骤S104可以为图6中的S304。
可选地,作为另一个实施例,若资源配置请求携带在RRC信令中,该步骤S104可以图5中的S204和S205。
S204,第一终端10确定发送资源。
具体地,第一终端10可以根据S203中的发送资源池配置信息,从发送资源池中选择发送资源。
S205,第一终端10使用在S204中所选择的发送资源,向第二终端20发送D2D数据。
这样,本发明实施例中,在半静态配置资源的过程中,发送端终端可以在专用信令(RRC信令)中包括接收端终端的设备属性信息,能够由基站根据设备属性信息,进行发送资源配置,从而能够保证发送端终端与接收端终端之间的D2D传输。
在发送端终端申请动态资源时,可以在MAC PDU中包括接收端终端的 设备属性信息,能够由基站根据设备属性信息,进行发送资源配置,从而能够保证发送端终端与接收端终端之间的D2D传输。
由此可见,本发明实施例中,第一终端向基站发送第二终端的设备属性信息,从而保证基站所分配的资源不会超出第二终端的能力接收范围,进而能够保证后续第一终端与第二终端之间的数据传输。
图8是本发明实施例的终端的一个结构示意图。图8所示的终端为第一终端10,包括发送单元110和接收单元120。
发送单元110用于向基站发送资源配置请求,所述资源配置请求包括第二终端的设备属性信息。
接收单元120用于接收所述基站发送的发送资源配置信息,其中,所述发送资源是所述基站根据所述设备属性信息确定的。
发送单元110还用于使用所述发送资源,向所述第二终端发送设备到设备D2D数据。
可选地,资源配置请求携带在RRC信令中。该第一终端10还可以包括选择单元。接收单元120具体用于接收所述基站发送的发送资源池配置信息,所述发送资源池包括所述发送资源。选择单元,用于从所述发送资源池中选择所述发送资源。
可选地,资源配置请求携带在MAC PDU中。
应注意,本发明实施例中,发送单元110可以由发送器实现,接收单元120可以由接收器实现,选择单元可以由处理器实现。如图9所示,第一终端10可以包括处理器701、接收器702、发送器703和存储器704。其中,存储器704可以用于存储处理器701执行的代码等。处理器701用于执行存储器704所存储的代码。例如,处理器701可以用于确定待发送的数据块的大小。
第一终端10中的各个组件通过总线系统705耦合在一起,其中总线系统705除包括数据总线之外,还包括电源总线、控制总线和状态信号总线。
图10是本发明实施例的系统芯片的另一个示意性结构图。图10的系统芯片80包括输入接口810、输出接口820、至少一个处理器830、存储器840,所述输入接口810、输出接口820、所述处理器830以及存储器840之间通过总线850相连,所述处理器830用于执行所述存储器840中的代码,当所述代码被执行时,所述处理器830实现图3中由第一终端执行的方法。
图8所示的第一终端10或图9所示的第一终端10或图10所示的系统芯片80能够实现前述图3至图6的方法实施例中由第一终端所实现的各个过程,为避免重复,这里不再赘述。
图11是本发明实施例的基站的一个结构框图。图11所示的基站30包括接收单元910、确定单元920和发送单元930。
