Abstract

本申请涉及无线通信技术领域,特别涉及一种进行反馈的方法、终端及计算机存储介质。用以解决目前针对发送端UE发送的有最大通信距离要求的业务数据块,还没有一种进行反馈的方案的问题。本申请实施例第一终端在接收到第二终端发送的业务数据块后,根据第一终端的第一位置信息以及第二终端的第二位置信息,确定第一终端与第二终端之间的距离;若第一终端与第二终端之间的距离不大于业务数据块对应的通信距离,第一终端向第二终端发送表示接收到业务数据块的反馈消息。由于在第一终端与第二终端之间的距离大于业务数据块对应的通信距离时,第一终端不再发送反馈消息,从而能够避免对系统造成干扰,同时避免因反馈不必要信息占用通信资源。

一种进行反馈的方法、终端及计算机存储介质
相关申请的交叉引用
本申请要求在2019年08月09日提交中国专利局、申请号为201910734607.5、申请名称为“一种进行反馈的方法、终端及计算机存储介质”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
本申请涉及无线通信技术领域,特别涉及一种进行反馈的方法、终端及计算机存储介质。
背景技术
车与万物(Vechile-to-Everything,V2X)通信是直接通信的一种。长期演进(Local Terminal Emulator,LTE)系统中约定支持V2X业务的用户设备(User Equipment,UE),其V2X业务的通信路径由高层(接入网以上的协议层)决定,且高层仅会向低层指示唯一的一条通信路径,即同一时刻仅选择直接通信链路作为通信路径或仅选择Uu链路作为通信路径。
对于5G新空口(New Radio,NR),V2X业务支持组播、广播业务。现有技术对于组播业务,当发送端UE发送数据后,同一组内的其它UE都可以接收该数据,且在其它UE在接收到该数据后都会向发送端UE发送反馈消息。但针对发送端UE发送的部分业务数据块,该业务的业务质量(Quality of Service,QoS)要求中有最大通信距离的要求,针对发送端UE发送的有最大通信距离要求的业务数据块,现有的反馈方式不再适用。
综上所述,目前针对发送端UE发送的有最大通信距离要求的业务数据块,还没有一种进行反馈的方案。

本申请实施例应用于5G NR下V2X组播业务使用直接通信链路进行通信的场景中,现有技术对于组播业务,当发送端UE发送数据后,同一组内的其它UE都可以接收该数据,且在其它UE在接收到该数据后都会向发送端UE发送反馈消息。但针对发送端UE发送的部分业务数据块,该业务的QoS要求中有最大通信距离的要求,针对发送端UE发送的有最大通信距离要求的业务数据块,大于该最大通信距离的接收端UE是否收到该业务数据块对业务而言并不重要,再向发送端UE发送反馈消息会增加对系统的干扰,同时也会造成资源的浪费。
针对上述问题,本申请实施例提供一种进行反馈的系统,如图2所示,该系统包括至少一个第一终端10和第二终端20。
第一终端10,用于在接收到第二终端发送的业务数据块后,根据所述第一终端的第一位置信息以及所述第二终端的第二位置信息,确定所述第一终端与所述第二终端之间的距离;若所述第一终端与所述第二终端之间的距离不大于所述业务数据块对应的通信距离,所述第一终端向所述第二终端发送表示接收到所述业务数据块的反馈消息。
第二终端20,用于向第一终端发送业务数据块,接收所述第一终端发送的表示接收到所述业务数据块的反馈消息;其中,所述反馈消息为所述第一终端根据所述第一终端的第一位置信息和所述第二终端的第二位置信息确定与所述第二终端之间的距离不大于所述业务数据块对应的通信距离之后发送的。
本申请实施例提供的反馈方法,第一终端在接收到第二终端发送的业务数据块后,根据第一终端的第一位置信息以及第二终端的第二位置信息,能够确定出第一终端与第二终端之间的距离。在第一终端与第二终端之间的距离不大于第二终端发送的业务数据块对应的通信距离时,第一终端在接收到该业务数据块后向第二终端发送反馈消息。由于第一终端在接收到业务数据块之后,需要根据自身与第二终端的距离判断是否向第二终端发送反馈消息, 只有在第一终端与第二终端之间的距离不大于业务数据块对应的通信距离时,才会向第二终端发送反馈消息,在第一终端与第二终端之间的距离大于业务数据块对应的通信距离时,第一终端不再发送反馈消息,从而能够避免不需要发送反馈消息的第一终端发送的反馈消息对系统造成的干扰,同时避免因反馈不必要信息占用通信资源。
其中,第一终端向第二终端发送的表示接收到所述业务数据块的反馈消息包括但不限于:
混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)、自动重传请求(Automatic Repeat Request,ARQ)、确认字符(Ackonwledge Character,ACK)、否认字符(Negative Acknowledge,NACK)。
所述业务数据块可以为各个协议层的业务数据块,比如物理层的传输块(Transport Block,TB),或者媒体接入控制(Medium Access Control,MAC)层/无线链路控制(Radio Link Control,RLC)层/分组数据聚合协议(Packet Data Convergence Protocol,PDCP)层/服务数据适配协议(Service Data Adaptation Protocol,SDAP)层的业务数据块。
V2X业务可以使用两种通信路径:直接通信链路或者Uu链路。当高层选择直接通信链路时,V2X业务的资源是基于区域进行选择。基站广播区域配置信息,以及每个区域下UE可以使用的资源池;其中,区域配置信息包括每个区域的长度、每个区域的宽度以及经度方向的区域个数、纬度方向的区域个数。例如,基站广播的区域配置信息可以如图3所示,基站广播的区域配置信息中在经度方向上包含三个区域,在纬度方向上包含2个区域,每个区域的长度为L,每个区域的宽度为W,其中,Zone0表示区域ID为0的区域、Zone1表示区域ID为1的区域、Zone2表示区域ID为2的区域、Zone3表示区域ID为3的区域、Zone4表示区域ID为4的区域、Zone5表示区域ID为5的区域。
UE在接收到基站的广播信息后,根据自身的GPS坐标可以计算出所属的区域ID,并使用基站的广播信息中指示的该区域ID对应的资源池。
