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)、全球互联微波接入(Worldwide Interoperability for Microwave Access,WiMAX)通信系统或5G系统等。
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进行通信。可选地,该网络设备110可以是GSM系统或CDMA系统中的基站(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),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备可以为移动交换中心、中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器、5G网络中的网络侧设备或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
该通信系统100还包括位于网络设备110覆盖范围内的至少一个终端120。作为在此使用的“终端”包括但不限于经由有线线路连接,如经由公共交换电话网络(Public Switched Telephone Networks,PSTN)、数字用户线路(Digital Subscriber Line,DSL)、数字电缆、直接电缆连接;和/或另一数据连接/网络;和/或经由无线接口,如,针对蜂窝网络、无线局域网(Wireless Local Area Network,WLAN)、诸如DVB-H网络的数字电视网络、卫星网络、AM-FM广播发送器;和/或另一终端的被设置成接收/发送通信信号的装置;和/或物联网(Internet of Things,IoT)设备。被设置成通过无线接口通信的终端可以被称为“无线通信终端”、“无线终端”或“移动终端”。移动终端的示例包括但不限于卫星或蜂窝电话;可以组合蜂窝无线电电话与数据处理、传真以及数据通信能力的个人通信系统(Personal Communications System,PCS)终端;可以包括无线电电话、寻呼机、因特网/内联网接入、Web浏览器、记事簿、日历以及/或全球定位系统(Global Positioning System,GPS)接收器的PDA;以及常规膝上型和/或掌上型接收器或包括无线电电话收发器的其它电子装置。终端可以指接入终端、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。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、5G网络中的终端或者未来演进的PLMN中的终端等。
可选地,终端120之间可以进行终端直连(Device to Device,D2D)通信。
可选地,5G系统或5G网络还可以称为新无线(New Radio,NR)系统或NR网络。
图1示例性地示出了一个网络设备和两个终端,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,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120,网络设备110和终端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。
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。
在第三代合作伙伴项目(3GPP,the 3rd Generation Partnership Project)Rel-14中对车联网技术(V2X,Vehicle-to-Everything)进行了标准化,定义了两种传输模式:模式3和模式4。在模式3中,终端的传输资源由基站分配。在模式4中,终端采用侦听(sensing)+预留(reservation)的方式确定传输资源。
模式3:如图2所示,车载终端的传输资源是由基站分配的,具体地,基站通过下行链路(DL,Down Link)向车载终端下发用于指示授权(Grant)资源的控制消息;而后,车载终端根据基站分配的资源在SL上进行数据的发送。在模式3中,基站可以为车载终端分配单次传输的资源,也可以为终端分配半静态传输的资源。
模式4:如图3所示,车载终端采用侦听+预留的传输方式。车载终端在资源池中通过侦听的方式获取可用的传输资源集合,车载终端从该传输资源集合中随机选取一个资源进行数据的传输。由于车联网系统中的业务具有周期性特征,因此车载终端通常采用半静态传输的方式,即车载终端选取一个传输资源后,就会在多个传输周期中持续的使用该资源,从而降低资源重选以及资源冲突的概率。车载终端会在本次传输的控制信息中携带预留下次传输资源的信息,从而使得其他终端可以通过检测该车载终端的控制信息判断这块资源是否被该车载终端预留和使用,达到降低资源冲突的目的。
需要说明的是,在LTE-V2X中分别使用模式3表示车载终端的传输资源是由基站分配的,用模式4表示车载终端的传输资源是终端自主选取的,在NR-V2X中,可以定义新的传输模式,本申请对此不做限定。
本申请实施例的全部技术方案,不仅适用于车联网系统中,也可以适用于其他端到端通信系统中,本申请实施例中的所述终端可以为车载终端、手持终端、掌上电脑(PDA, Personal Digital Assistant)、可穿戴式终端等等,本申请实施例中的所述网络可以为NR网络、LTE网络等等。
图4为本申请实施例提供的信息生成方法的流程示意图,如图4所示,所述信息生成方法包括以下步骤:
步骤401:第一终端基于第二信息和第一门限,生成第一信息;其中,所述第一信息用于指示目标接口的资源情况,所述目标接口包括第一接口和/或第二接口,所述第一接口用于传输所述第一终端与第二终端之间的信号,所述第二接口用于传输所述第一终端与基站之间的信号。
本申请实施例中,所述第一终端可以为车载终端、手持终端、PDA、可穿戴式终端等等。所述第二终端可以为车载终端、手持终端、PDA、可穿戴式终端等等。所述第一终端和所述第二终端的类型可以相同,也可以不同。例如:所述第一终端为手持终端,所述第二终端为车载终端。再例如:所述第一终端为车载终端A,所述第二终端为车载终端B。
本申请实施例中,第一终端至少具有第一接口和第二接口,其中,所述第一接口用于传输所述第一终端与第二终端之间的信号,所述第二接口用于传输所述第一终端与基站之间的信号。这里,所述第一接口为侧行链路接口;所述第二接口为上行链路接口和/或下行链路接口。
需要说明的是,所述上行链路接口和所述下行链路接口可以是同一个接口,也可以是独立的两个接口。
本申请实施例中,第一终端基于第二信息和第一门限,生成第一信息,所述第一信息用于指示目标接口的资源情况。这里,第一终端的第一接口和第二接口可以共享一个第一信息,也可以是第一接口和第二接口分别对应独立的第一信息。举个例子:通过一个第一信息对第一接口和/或第二接口的资源情况进行联合指示。再举个例子:通过一个第一信息对第一接口的资源情况进行指示,通过另一个第一信息对第二接口的资源情况进行指示。
本申请实施例中,所述第一信息用于指示目标接口的资源情况,具有如下两种实现方式:
方式一:所述第一信息用于指示目标接口是否可以进行数据传输。
在一个例子中,所述第一信息包括一个位图(bitmap),该位图包括2比特,第一个比特对应第一接口,第二个比特对应第二接口,每个比特的取值代表对应的接口是否可 以进行数据传输,如比特取值为“1”代表对应的接口可以进行数据传输,比特取值为“0”代表对应的接口不可以进行数据传输。
在另一个例子中,所述第一信息包括1比特信息,第一接口和第二接口分别对应独立的所述第一信息,该1比特信息的取值代表对应的接口是否可以进行数据传输,如比特取值为“1”代表对应的接口可以进行数据传输,比特取值为“0”代表对应的接口不可以进行数据传输。
方式二:所述第一信息用于指示目标接口的物理层参数。
这里,所述物理层参数包括以下至少之一:调制解调方式、子信道数量、重传次数、发送功率。
需要说明的是,所述第一信息指示的是物理层参数的范围。第一终端根据第一信息可以从该范围中选择一个物理层参数,并将选择的物理层参数与第一接口和第二接口进行匹配,对于与物理层参数匹配的接口可以进行数据传输,对于与物理层参数不匹配的接口不可以进行数据传输。
本申请实施例中,所述第一信息是第二信息与第一门限进行比较生成,以下对第二信息的具体实现进行说明。
所述第二信息包括以下至少之一:侧行链路资源的繁忙比例、侧行链路的信道质量信息、下行链路的信道质量信息、物理层参数的范围。其中:
1)侧行链路资源的繁忙比例(channel busy ratio):
这里,侧行链路资源的繁忙比例表明了侧行链路资源的繁忙程度,侧行链路资源越繁忙,则可用(也即空闲)的侧行链路资源就越少,反之,侧行链路资源越不繁忙,则可用(也即空闲)的侧行链路资源就越多。为了均衡网络的负载,可以将侧行链路资源的繁忙比例与一个设定的第一门限进行比较,如果侧行链路资源的繁忙比例大于等于该第一门限,则生成的第一信息倾向于使用第二接口传输信号;如果侧行链路资源的繁忙比例小于该第一门限,则生成的第一信息倾向于使用第一接口传输信号,通过第一接口实现更高的频谱效率以及更低的传输时延。
2)侧行链路的信道质量信息:
这里,所述侧行链路的信道质量信息包括以下至少之一:
侧行链路的参考信号接收功率(Reference Signal Received Power,RSRP)测量结果、侧行链路的参考信号接收质量(Reference Signal Received Quality,RSRQ)测量结果、侧行链路的接收信号强度指示(Received Signal Strength Indicator,RSSI)测量结果、侧 行链路的信干噪比(Signal to Interference Noise Ratio,SINR)测量结果。
这里,所述侧行链路的信道质量信息表明了侧行链路的信道质量好坏,为了优化业务的传输质量,可以将侧行链路的信道质量信息与一个设定的第一门限进行比较,如果比较结果表明侧行链路的信道质量较差,则生成的第一信息倾向于使用第二接口传输信号;如果比较结果表明侧行链路的信道质量较好,则生成的第一信息倾向于使用第一接口传输信号,通过第一接口实现更高的频谱效率以及更低的传输时延。
3)下行链路的信道质量信息:
这里,所述下行链路的信道质量信息包括以下至少之一:
下行链路的RSRP测量结果、下行链路的RSRQ测量结果、下行链路的RSSI测量结果、下行链路的SINR测量结果。进一步,所述下行链路的信道质量信息是指:所述终端当前接入的网络的下行链路的信道质量信息;或者,所述终端当前驻留的网络的下行链路的信道质量信息。
这里,所述下行链路的信道质量信息表明了下行链路的信道质量好坏,为了优化业务的传输质量,可以将下行链路的信道质量信息与一个设定的第一门限进行比较,如果比较结果表明下行链路的信道质量较差,则生成的第一信息倾向于使用第一接口传输信号;如果比较结果表明下行链路的信道质量较好,则生成的第一信息倾向于使用第二接口传输信号。
4)物理层参数的范围:
这里,所述物理层参数包括以下至少之一:调制解调方式、子信道数量、重传次数、发送功率。其中,所述物理层参数根据以下至少一项生成:侧行链路资源的繁忙比例、侧行链路的信道质量信息、侧行链路的QoS属性信息。进一步,所述侧行链路的QoS属性信息至少包括优先级信息。
需要说明的是,第一终端获取到上述物理层参数的范围后,可以从该范围中选择一个物理层参数,并将选择的物理层参数与第一接口和第二接口进行匹配,对于与物理层参数匹配的接口可以进行数据传输,对于与物理层参数不匹配的接口不可以进行数据传输。
本申请实施例的上述方案中,所述第一门限由网络配置或者预配置。举个例子:网络通过非接入层(Non-Access Stratum,NAS)信令或无线资源控制(Radio Resource Control,RRC)信令配置。
在一个应用场景中,所述第一终端至少具有三层协议实体,分别为第一协议实体、 第二协议实体和第三协议实体。其中,第一协议实体例如是V2X层,第二协议实体例如是接入层,第三协议实体例如是应用层。所述第三协议实体位于所述第一协议实体的上层,所述第二协议实体位于所述第一协议实体的下层。
基于此,所述方法还包括:所述第一终端的第一协议实体向第三协议实体上报所述第一信息。
这里,所述第一终端的第一协议实体侧的第二信息和第一门限,可以通过以下方式确定:
1)第二信息的确定:所述第二信息由第一协议实体获取;或者,所述第二信息由第二协议实体上报给第一协议实体。
2)第一门限的确定:所述第一门限由第一协议实体获取;或者,所述第一门限由第二协议实体上报给第一协议实体。
本申请实施例的上述方案中,所述第一门限、所述第二信息、以及所述第一信息,根据不同情况有不同的取值,具体如下:
1)所述第一门限的取值基于以下至少一种参考信息确定:QoS属性信息、传播方式、接入类型、资源池类型、服务提供商标识(Provider Service Identifier,PSID)、目标地址、源地址。
