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。针对本申请中的实施例,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。
本申请实施例可以适用于任何终端设备到终端设备的通信框架。
例如,车辆到车辆(Vehicle to Vehicle,V2V)、车辆到其他设备(Vehicle to Everything,V2X)、终端到终端(Device to Device,D2D)等。
其中,本申请实施例中的终端可以是任何配置有物理层和媒体接入控制层的设备或装置,终端设备也可称为接入终端。例如,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、个人数字线性处理(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线性处理设备、车载设备、可穿戴设备等等。本申请实施例以车载终端为例进行说明,但并不限于此。
可选地,在本申请的一些实施例中,本申请实施例可以适用于第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)定义了两种传输模式,分别记为:模式A和模式B。
图1是本申请实施例的模式A的示意图。图2是本申请实施例的模式B的示意图。
在图1所示的模式A中,车载终端(车载终端121和车载终端122)的传输资源是由基站110分配的,车载终端根据基站110分配的资源在侧行链路上进行数据的发送。具体地,基站110可以为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。
在图2所示的模式B中,车载终端(车载终端131和车载终端132)采用侦听(sensing)加预留(reservation)的传输方式,车载终端在侧行链路的资源上自主选取传输资源进行数据传输。
下面以车载终端131为例进行具体说明。
车载终端131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131从该集合中随机选取一个传输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,本申请实施例中,车载终端131还可以采用半静态传输的方式。即车载终端131获取一个传输资源后,在多个传输周期中持续的使用该传输资源,以降低资源重选以及资源冲突的概率。
车载终端131可以在本次传输的控制信息中携带预留下次传输资源的信息,使得其他终端(例如,车载终端132)可以通过检测该用户的控制信息判断这块资源是否被该用户预留和使用,达到降低资源冲突的目的。
需要说明的是,在新空口(New Radio,NR)车辆到其他设备(Vehicle to Everything,V2X)中,用户可能处在一个混合的模式下,即既可以使用模式A进行资源的获取,又同时可以使用模式B进行资源的获取。
同时在NR V2X中,在系统设计上要求终端设备进行连续的发送和接收。然而,终端设备在侧行链路上进行连续的发送和接收,在侧行链路和上下行链路重用发送/接收能力的情况下,可能会导致侧行链路通信和终端设备空闲态寻呼接收的冲突,也可能会导致侧行链路通信和随机接入配置的冲突,还可能会导致侧行链路通信和下行非连续接收(Discontinuous Reception,DRX)配置的冲突。
基于上述技术问题,本申请设计了一种无线通信方法,可以避免侧行通信与蜂窝通信之间的冲突。

实施例四,如图8所示,UE 1可以是上述第一终端设备,NW 1可以是上述第一网络设备,UE 2可以是上述第二终端设备,NW 2可以是上述第二网络设备。UE 1处于RRC连接状态,即UE 1与NW 1之间的蜂窝网络已建立,UE 1与UE 2之间的侧行链路已建立。UE 1可以通过接收NW 1发送的RRC信令获取第一时域资源和第二时域资源。UE 1可以在第一时域资源上与UE 2进行侧行通信, UE 1可以在第二时域资源上与NW 1进行蜂窝通信。UE 1接收UE 2发送的第一信息,该第一信息用于指示UE 2用于进行蜂窝通信的资源信息;UE 1向NW 1发送第三信息,该第三信息用于指示该第二终端设备用于进行蜂窝通信的资源信息;UE 1接收NW 1发送的第四信息,该第四信息用于指示UE 1和/或UE 2用于进行侧行通信的资源信息;以及UE 1向UE 2发送第二信息,该第二信息用于指示UE 2与UE 1进行侧行通信的资源信息。当UE 1的侧行通信与蜂窝通信发生冲突时,UE 1可以基于第一优先级顺序进行通信。
可选地,该第四信息还用于指示UE 1用于进行下行接收和/或上行发送的资源信息。
需要注意的是,若UE 1为发送端设备,UE 2为接收端设备,该第一信息和该第三信息具体用于指示UE 2用于进行下行接收和/或上行发送的资源相关信息,例如,用于下行寻呼接收的资源信息,又例如,用于上行随机接入发送的资源信息;该第二信息具体用于指示UE 2与UE 1进行侧行接收的资源相关信息。若UE 1为接收端设备,UE 2为发送端设备,该第一信息和该第三信息具体用于指示UE 2用于进行上行发送的资源相关信息,例如,用于上行随机接入发送的资源信息;该第二信息具体用于指示UE 2与UE 1进行侧行发送的资源相关信息。
需要说明的是,在实施例四中,UE 2也可以执行与UE 1类似的操作,以在UE 2的侧行通信与蜂窝通信发生冲突时,UE 2可以基于第一优先级顺序进行通信。
在上述实施例二或实施例四描述的是单播的场景,对于组播的场景同样适用。具体来说,
UE 1与至少一个终端设备之间建立了侧行链路,该至少一个终端设备包括UE 2,UE 1接收该至少一个终端设备分别发送的至少一个第一信息,该至少一个第一信息用于指示该至少一个第一信息对应的该至少一个终端设备用于进行蜂窝通信的资源信息;UE 1向NW 1发送第五信息,该第五信息用于指示该至少一个终端设备用于进行蜂窝通信的资源信息;UE 1接收NW 1发送的第六信息,该第六信息用于指示该至少一个终端设备与UE 1进行侧行通信的资源信息;UE 1分别向该至少一个终端设备发送至少一个第二信息,该至少一个第二信息用于指示该至少一个终端设备与UE 1进行侧行通信的资源信息。当UE 1的侧行通信与蜂窝通信发生冲突时,UE 1可以基于第一优先级顺序进行通信。当然,UE 2也可以执行与UE 1类似的操作,以在UE 2的侧行通信与蜂窝通信发生冲突时,UE 2可以基于第一优先级顺序进行通信。
因此,在本申请实施例中,在第一终端设备与第二终端设备之间的侧行通信和第一终端设备与第一网络设备之间的蜂窝通信之间发生冲突的情况下,第一终端设备根据第一优先级顺序进行通信,由于第一优先级顺序是根据业务属性确定,因此,第一终端设备可以基于业务属性灵活选择业务进行传输,从而可以在侧行链路和上下行链路上进行非连续传输,进而有利于第一终端设备实现省电。
应理解,本申请实施例中的无线通信方法200和无线通信方法300中的相关描述可以相互参考。
