Description

一种通信距离计算方法及装置
本申请要求于2020年3月2日提交中国专利局、申请号为202010136455.1、发明名称为“一种通信距离计算方法及装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域,具体涉及一种通信技术计算方法及装置。
背景技术
车用无线通信技术(Vehicle to Everything ,V2X)是将车辆与一切事物相连接的新一代信息通信技术,其中V代表车辆,X代表任何与车交互信息的对象,当前X主要包含车、人、交通路侧基础设施和网络。V2X交互的信息模式包括:车与车之间(Vehicle to Vehicle ,V2V)、车与路之间(Vehicle to Infrastructure ,V2I)、车与人之间(Vehicle to Pedestrian ,V2P)、车与网络之间(Vehicle to Network ,V2N)的交互。为了满足车与多种对象中的交互,特别是两个用户设备(User Equipment,UE)之间的直接通信,引入了直连通信(Sidelink,或译为侧链路,边链路等)方式。Sidelink通信方式通过媒体接入控制层(Media Access Control,MAC)的源标识和目标标识来实现寻址。在传输之前,UE之间不需要预先连接。Sidelink以此来满足更加快捷且高效的通信方式。系统架构(SA: System Architecture)工作组1 (WG1: work group 1)在[3GPP TR 22.186]中定义了支持增强V2X用例的第一阶段需求,大致分为四个用例:车辆编队行驶(Vehicles Platooning)、扩展传感器(Extended Sensors)、高级驾驶(Advanced Driving)、远程驾驶(Remote Driving)。
Sidelink中引入了groupcast(群组传播)的概念,主要针对上面描述的车辆编队行驶的用例。在groupcast中物理层支持混合自动重传(HARQ: Hybrid Automatic Repeat request)反馈和混合自动重传合并的功能。当为groupcast启用sidelink HARQ反馈时,支持使用TX-RX(发射端-接收端)距离和/或参考信号接收功率(RSRP:Reference Signal Receiving Power)来决定是否发送HARQ反馈。在3GPP RAN1 #97会议中,各公司已经达成一致,针对groupcast中基于TX-RX距离的HARQ反馈,如果TX-RX距离小于或等于通信距离要求 (communication range requirement),则UE为物理侧链路共享信道(PSSCH: Physical Sidelink Shared Channel)传输HARQ反馈。否则,UE不会为PSSCH传输HARQ反馈。并且上面提到的通信距离要求可通过解码SCI来获得。
目前3GPP已经确认会支持基于TX-RX距离的groupcast的HARQ反馈(仅反馈NACK)。区域(zone)划分是基于实际的地理区域来配置的,并且发射端所在的区域的编号(zone ID)是由SCI来承载的。然而,对于物理层来讲,如果不依赖非3gpp技术,很难获得TX-RX的距离。全球导航卫星系统(GNSS:Global Navigation Satellite System)在隧道中或者是城市中障碍影响的下性能很差。即使在城市中心的糟糕情况下,GNSS也可能无法在很大的区域下或者车辆很多的情况下保持准确度。在这种情况下,如何处理无法获取的发射端位置信息便是我们要解决的问题。

本发明的实施方式
本申请实施例提供一种通信距离计算方法和装置。其中,该应用装置集成在移动终端中,该终端可以为车载终端等设备。
以下分别进行详细说明。需说明的是,以下实施例的描述顺序不作为对实施例优选顺序的限定。
一种通信距离计算方法,包括:存储发射端的历史位置信息;根据所述历史位置信息获取位置载入数据,载入所述位置载入数据至侧链路控制信息;传输所述侧链路控制信息至接收端,计算所述发射端与所述接收端的距离。
如图1所示,该通信距离计算方法的具体流程可以如下:
101、存储发射端的历史位置信息。
例如,发射端将通过全球导航卫星系统获得的位置信息存储起来,在GNSS信号丢失而不能获得发射端的位置信息时,发射端存储的位置信息作为历史位置信息。
102、根据所述历史位置信息获取位置载入数据,载入所述位置载入数据至侧链路控制信息。
例如,当作为发射端的车辆行驶在隧道里或者是市中心拥堵的街道上的时候,虽然GNSS信号很容易丢失,但是此时车辆的行驶速度不会很高,尤其是拥堵的道路上,车辆的速度是很低的。此时,发射端将会复用存储的历史位置信息中最近一次的历史位置信息,将此位置信息作为此时发射端的位置信息。
其中,在发射端处于拥堵情形时,发射端所复用的历史位置信息即作为发射端的位置载入数据载入至第二级侧链路控制信息中。在发射端无法正常获得其位置信息时,将位置载入数据作为发射端的位置信息来计算接收端与发射端的距离。
其中,当作为接收端的车辆行驶在高速公路上时,行驶的方向和速度都是很有规律的,此时发射端计算其位置偏移量,根据计算获得的位置偏移量对发射端存储的最近一次的历史位置信息进行修正,将修正后的发射端的位置信息作为位置载入数据载入第二级侧链路控制信息中。
其中,在作为发射端的车辆处于行驶方向和速度规律的情形时,发射端可以对车辆的行进位移进行预测,将此位移量化生成发射端的位置偏移量,发射端的位置偏移量与最近一次的历史位置信息之和即此时发射端的位置信息。
103、传输所述侧链路控制信息至接收端,计算所述发射端与所述接收端的距离。
例如,发射端向接收端传输第二级侧链路控制信息,发射端与接收端的距离是在接收端中进行计算的,接收端的位置信息可以获取,且接收了发射端传输的第二级侧链路控制信息,从中获得发射端此时的位置信息,再根据发射端和接收端的位置计算得到两个用户设备之间的距离。
一种通信距离计算方法,包括:载入发射端的历史位置信息至侧链路控制信息,接收所述侧链路控制信息,并存储所述历史位置信息;根据所述历史位置信息获取所述发射端的位置载入数据,计算所述发射端与接收端的距离。
如图2所示,该通信距离计算方法的具体流程可以如下:
201、载入发射端的历史位置信息至侧链路控制信息,接收所述侧链路控制信息,并存储所述历史位置信息。
例如,发射端通过全球导航卫星系统获得的位置信息传输给接收端,接收端接收发射端传输的位置信息并存储起来,当GNSS信号丢失而不能获得发射端的位置信息时,发射端不再向接收端传输位置信息,此时接收端之前存储的发射端的位置信息即发射端的历史位置信息。
其中,发射端的位置信息载入到第二级侧链路控制信息中向接收端传输,接收端通过接收第二级侧链路控制信息获取发射端的位置信息。
202、根据所述历史位置信息获取所述发射端的位置载入数据,计算所述发射端与接收端的距离。
例如,当作为发射端的车辆行驶在隧道里或者是市中心拥堵的街道上的时候,虽然GNSS信号很容易丢失,但是此时车辆的行驶速度不会很高,尤其是拥堵的道路上,车辆的速度是很低的。此时,接收端将会复用其存储的发射端历史位置信息中最近一次的历史位置信息,将此位置信息作为此时发射端的位置信息。
其中,接收端会接收并存储每一次发射端传输来的位置信息,新的位置信息会覆盖旧的位置信息。
其中,当作为接收端的车辆行驶在高速公路上时,行驶的方向和速度都是很有规律的,此时发射端会计算其位置偏移量,将位置偏移量通过侧链路控制信息传输给接收端。接收端接收发射端的位置偏移量,根据此位置偏移量和其存储的发射端历史位置信息计算发射端的位置载入数据。在发射端无法正常获得其位置信息时,将位置载入数据作为发射端的位置信息来计算接收端与发射端的距离。
其中,在作为发射端的车辆处于行驶方向和速度规律的情形时,发射端可以对车辆的行进位移进行预测,将此位移量化生成发射端的位置偏移量。发射端的位置偏移量可以通过第一级侧链路控制信息传输,也可以通过第二级侧链路控制信息传输。
其中,接收端可以获取接收端自己的位置信息,并且通过接收的侧链路控制信息中的发射端偏移量,对存储的发射端历史位置信息进行修正,从而得到修正过的发射端的位置信息,再根据发射端和接收端的位置计算得到接收端与发射端之间的距离。
为了更好地实施以上方法,本申请实施例还可以提供一种通信距离计算装置,该通信距离计算装置具体可以集成在网络设备中,该网络设备可以是移动终端等设备。
例如,如图3所示,该通信距离计算装置可以包括存储单元301、获取单元302、传输单元303,如下:
(1)存储单元301
存储单元301,用于存储发射端的历史位置信息。
例如,存储单元将发射端通过全球导航卫星系统获得的位置信息存储起来,在GNSS信号丢失而不能获得发射端的位置信息时,存储单元中存储的位置信息即发射端的历史位置信息。
(2)获取单元302
获取单元302,用于根据所述历史位置信息获取位置载入数据,载入所述位置载入数据至侧链路控制信息。
例如,当作为发射端的车辆行驶在隧道里或者是市中心拥堵的街道上的时候,此时车辆的行驶速度不会很高,尤其是拥堵的道路上,车辆的速度很低,获取单元复用发射端最近一次的历史位置信息作为位置载入数据,将位置载入数据载入第二级侧链路控制信息中。
其中,当作为发射端的车辆行驶在高速公路上,车辆的行驶方向和速度规律时,获取单元还包括计算单元,用于计算发射端的位置偏移量,以及根据位置偏移量和存储的历史位置信息计算位置载入数据。
(3)传输单元303
传输单元303,用于向接收端传输所述侧链路控制信息。
例如,传输单元将包含发射端位置载入数据的第二级侧链路控制信息传输至接收端。
为了更好地实施以上方法,本申请实施例还可以提供另一种通信距离计算装置,该通信距离计算装置具体可以集成在网络设备中,该网络设备可以是终端等设备。
例如,如图4所示,该通信距离计算装置可以包括接收单元401、获取单元402,如下:
(1)接收单元401
接收单元401,用于接收发射端的历史位置信息。
例如,发射端的位置信息载入到第二级侧链路控制信息中,接收单元接收发射端传输的第二级侧链路控制信息即接收发射端的位置信息。接收端将发射端的位置信息存储起来。
(2)获取单元402
获取单元402,用于根据所述历史位置信息获取发射端的位置载入数据。
例如,在作为发射端的车辆发生拥堵时,获取单元将复用接收端存储的最近一次的发射端历史位置信息作为位置载入数据。
其中,当作为发射端的车辆行驶在高速公路上,车辆的行驶方向和速度规律时,获取单元将接收发射端传输的位置偏移量,根据此位置偏移量和其存储的发射端历史位置信息计算发射端的位置载入数据。
在发射端无法通过GNSS获取发射端的位置信息的情况下,通过本申请实施例中的通信距离计算方法中对发射端及接收端的操作,计算得到发射端至接收端的距离。本方案计算的发射端至接收端的距离可以应用于车用无线通信技术中的车辆编队行驶用例中,将计算得到的发射端至接收端的距离与通信距离要求进行比较,从而判断是否进行HARQ反馈。
在车用无线通信技术中的车辆编队行驶用例中,引入了群组传播,当为群组传播启用HARQ反馈时,支持使用TX-RX(发射端-接收端)距离和/或参考信号接收功率来决定是否发送HARQ反馈。群组传播的HARQ反馈支持两种选项:选项1:如果接收端UE在解码相关的物理侧链路控制信道(PSCCH: Physical Sidelink Control Channel)后未能解码相应的传输块(TB: Transport Block),则在物理侧链路反馈信道(PSFCH: Physical Sidelink Feedback Channel)上传输HARQ-NACK(NACK: non-acknowledgement,解码失败)。否则在PSFCH上不发送信号。选项2:如果接收端UE成功解码了相应的TB,则在PSFCH上传输HARQ-ACK(ACK: acknowledgement,解码成功)。在解码了以接收机UE为目标的相关PSCCH后,如果不能成功解码对应的TB,则在PSFCH上传输HARQ-NACK。如果TX-RX距离小于或等于通信距离要求 (communication range requirement),则UE为物理侧链路共享信道传输HARQ反馈,否则,UE不传输HARQ反馈。并且上面提到的通信距离要求可通过解码SCI(Sidelink Control Information,侧链路控制信息)来获得。关于接收端和发射端之间的距离是由接收端来计算的,发射端的位置信息会通过第二级SCI(2nd stage SCI)来承载。此时默认发射端的位置信息是可以获得的,通过第二级SCI传给接收端来进行计算。如果此时无法获得发射端的位置信息,本申请实施例提供的通信距离计算方法就适用于此时的情况下。
