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。
应理解,本申请实施例的技术方案可以应用于端到端(Device to Device,D2D)通信系统,例如,基于长期演进(Long Term Evolution,LTE)进行D2D通信的车联网系统,或者基于新无线的车辆到其他设备(New Radio Vehicle to Everything,NR-V2X)系统。与传统的LTE系统中终端之间的通信数据通过网络设备(例如,基站)接收或者发送的方式不同,车联网系统采用终端到终端直接通信的方式,因此具有更高的频谱效率以及更低的传输时延。
可选地,车联网系统基于的通信系统可以是全球移动通讯(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)、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、5G新无线(New Radio,NR)系统等。
本申请实施例中的终端设备可以是能够实现D2D通信的终端设备。例如,可以是车载终端设备,也可以是5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等,本申请实施例并不限定。
图1是本申请实施例的一个应用场景的示意图。图1示例性地示出了一个网络设备和两个终端设备,可选地,本申请实施例中的无线通信系统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设备,本申请实施例对此不做限定。
可选地,该无线通信系统还可以包括移动管理实体(Mobile Management Entity,MME)、服务网关(Serving Gateway,S-GW)、分组数据网络网关(Packet Data Network Gateway,P-GW)等其他网络实体,或者,该无线通信系统还可以包括会话管理功能(Session Management Function,SMF)、统一数据管理(Unified Data Management,UDM),认证服务器功能(Authentication Server Function,AUSF)等其他网络实体,本申请实施例对此不作限定。
在该车联网系统中,终端设备可以采用模式A和模式B进行通信。
具体地,终端设备121和终端设备122可以通过D2D通信模式进行通信,在进行D2D通信时,终端设备121和终端设备122通过D2D链路即侧行链路(SideLink,SL)直接进行通信。其中,在模式A中,终端设备的传输资源是由基站分配的,终端设备可以根据基站分配的资源在SL上进行数据的发送。基站可以为终端设备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。在模式B中,终端设备采用侦听(sensing)加预留(reservation)的传输方式,终端设备在SL资源上自主选取传输资源。具体的,终端设备在资源池中通过侦听的方式获取可用的传输资源集合,终端设备从该可用的传输资源集合中随机选取一个资源进行数据的传输。
应理解,上述模式A和模式B只是示例性的说明两种传输模式,可以定义其他的传输模式。例如,在NR-V2X中引入了模式C和模式D,其中,模式C表示终端设备的侧行链路传输资源是由基站分配的,模式D表示终端设备的侧行链路传输资源是终端选取的。
D2D通信可以指车对车(Vehicle to Vehicle,简称“V2V”)通信或车辆到其他设备(Vehicle to Everything,V2X)通信。在V2X通信中,X可以泛指任何具有无线接收和发送能力的设备,例如但不限于慢速移动的无线装置,快速移动的车载设备,或是具有无线发射接收能力的网络控制节点等。应理解,本发明实施例主要应用于V2X通信的场景,但也可以应用于任意其它D2D通信场景,本申请实施例对此不做任何限定。
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。
图2是根据本申请实施例的无线通信的方法的示意性流程图,例如,该方法可以由车联网系统中的终端设备执行,例如终端设备121或终端设备122,如图2所示,该方法200包括:
S210,第一终端触发侧行链路缓存状态报告BSR,所述侧行链路BSR用于为待发送的第一侧行数据请求侧行链路资源;
S220,所述第一终端根据第一信息,确定是否触发用于请求所述侧行链路资源的调度请求SR。
具体而言,该第一终端在需要向其他终端,例如第二终端发送侧行数据时,需要有侧行链路资源,如果没有侧行链路资源,则需要向网络设备请求侧行链路资源,这种情况下,该终端设备可以触发侧行链路BSR,该侧行链路BSR可以用于请求用于侧行数据传输的侧行链路资源。
可选地,在本申请实施例中,待发送的该第一侧行数据可以为触发该侧行链路BSR的逻辑信道,或触发该侧行链路BSR的逻辑信道组(Logic Channel Group,LCG)。
也就是说,当逻辑信道或逻辑信道组中的数据需要发送给其他终端设备时,该第一终端可以触发侧行链路BSR。
应理解,在本申请实施例中,第一终端触发了侧行链路BSR,该侧行链路BSR此时处于暂停(Pending)状态,也就是说,该第一终端准备发送但并没有向网络设备发送该侧行链路BSR。
可选地,所述第一侧行数据包括数据无线承载(Data Radio Bearer,DRB)中的数据,和/或信令无线承载(Signalling Radio Bearer,SRB)中的数据。
可选地,在一些实施例中,所述SRB可以用于承载侧行链路的无线资源控制(Radio Resource Control,RRC)信令和/或侧行链路PC5接口信令(PC5Signalling,PC5-S)。
可选地,在一些实施例中,所述SRB的QoS属性是由网络设备配置的或者是预配置的。
可选地,所述SRB的QoS属性可以包括优先权,可选地,还可以包括时延等其他属性。
可选地,在一些实施例中,该第一终端可以在触发侧行链路BSR的情况下,根据第一信息,确定是否触发SR,以通过该SR请求侧行链路资源。
应理解,在本申请实施例中,若确定触发SR,则可以不发送侧行链路BSR,第一终端向网络设备发送SR之后,网络设备可以给第一终端分配侧行链路资源,若该侧行资源不能满足侧行数据的传输需求,例如,侧行链路资源的大小不足够传输待发送的第一侧行数据,则该第一终端还可以进一步触发侧行链路BSR,通过侧行链路BSR向网络设备请求侧行链路资源。
可选地,在一些实施例中,若所述第一终端确定不触发SR,例如,该第一终端上未配置上行授权资源,则该第一终端还可以发起随机接入过程,向网络设备请求上行授权资源。
以下,结合具体实施例,说明SR的触发方式。
可选地,作为一个实施例,记为实施例1,所述第一信息可以包括:
所述第一终端是否有用于初传的可用侧行链路资源,和/或所述用于初传的可用侧行链路资源是否满足所述第一侧行数据的传输需求。
例如,若该第一终端上没有配置用于初传的可用侧行链路资源,该第一终端可以确定触发SR,进一步向网络设备发送所述SR。
又例如,若所述第一终端上配置有用于初传的可用侧行链路资源,则该第一终端可以确定不触发SR。
因此,所述第一终端可以根据是否有用于初传(即新传)的可用侧行链路资源确定是否触发SR。
在另一些实施例中,若所述第一终端上配置有用于初传的可用侧行链路资源,该第一终端还可以进一步根据该可用侧行链路资源是否满足所述第一侧行数据的传输需求,确定是否触发SR,这样,有利于保证请求的侧行链路资源能够满足侧行数据的传输需求。
例如,若所述第一终端上配置有用于初传的可用侧行链路资源,但是若该可用侧行链路资源不能满足待发送的所述第一侧行链路数据的传输需求,则该第一终端可以确定触发SR,进一步向网络设备发送SR。
或者,若所述第一终端上配置有用于初传的可用侧行链路资源,但是若该可用侧行 链路资源能够满足待发送的所述第一侧行链路数据的传输需求,则该第一终端可以确定不触发SR,使用该可用侧行链路资源发送该第一侧行链路数据。
作为示例而非限定,所述可用侧行链路资源不能满足所述第一侧行数据的传输需求包括以下中的至少一项:
所述可用侧行链路资源和所述第一侧行数据不满足第一映射关系;
所述可用侧行链路资源不满足所述第一侧行数据的时延要求;
所述可用侧行链路资源的大小不足够传输所述第一侧行链路数据。
因此,在本申请实施例中,在第一终端上配置有可用链路资源的情况下,该第一终端可以进一步根据该可用链路资源的属性确定是否满足实际的传输需求,确定是否触发SR,从而能够在该可用链路资源不满足实际传输需求的情况下,触发SR,进一步通过SR请求侧行链路资源,有利于保证请求到满足实际传输需求的侧行链路资源。
应理解,本申请实施例中,可用侧行链路资源不能满足所述第一侧行数据的传输需求的情况仅为示例,侧行数据的传输需求还可以包括其他影响传输性能的参数,例如,服务质量(Quality-of-Service,QoS)需求,优先级,可靠性需求等,本申请实施例对此不作具体限定。
可选地,在一些实施例中,所述第一映射关系可以为触发所述侧行链路BSR的侧行数据和侧行链路资源的属性的映射关系。
例如,该第一映射关系可以为触发所述侧行链路BSR的逻辑信道或逻辑信道组和侧行链路资源的属性之间的关系。
也就是说,触发所述侧行链路BSR的侧行数据需要对应特定属性的侧行链路资源,若可用侧行链路资源的属性与该第一侧行数据所映射的侧行链路资源的属性不同,则所述可用侧行链路资源和所述第一侧行数据不满足第一映射关系,此情况下,该第一终端可以触发SR,通过SR进一步请求满足侧行链路资源,有利于请求到满足该第一映射关系的特定属性的侧行链路资源。
可选地,在一些实施例中,若该第一终端上配置有用于初传的可用侧行链路资源,该第一终端也可以进一步结合当前数据的组包情况,确定是否触发SR,例如,若该数据已组包完成,也就是说,不能再将BSR组装到该数据包中,此情况下,该第一终端可以触发SR,具体地,可以向网络设备发送(Physical Uplink Control Channel,PUCCH),通过该PUCCH将SR发送给网络设备。
可选地,作为另一实施例,记为实施例2,该第一信息也可以包括以下中的至少一项:
所述第一终端是否有可用的物理上行控制信道PUCCH资源,和/或所述SR的冲突 数据的信息。
可选地,所述PUCCH资源为所述第一侧行数据对应的逻辑信道或逻辑信道组所映射的PUCCH资源。
以下,结合实施例3~实施例9,说明该实施例2的具体实现方式。
实施例3:该第一终端根据该第一终端是否配置有可用的PUCCH资源确定是否触发SR。
该SR可以通过PUCCH资源来发送,在一些具体实施例中,该第一终端根据该第一终端是否配置有可用的PUCCH资源确定是否触发SR,例如,该第一终端可以在配置有可用的PUCCH资源的情况下,确定触发SR,或者在没有配置可用的PUCCH资源的情况下,确定不触发SR。
实施例4,该第一终端也可以根据所述SR的冲突数据的信息,确定是否触发SR。
作为示例而非限定,所述SR的冲突数据的信息包括以下中的至少一项:
是否有与所述SR冲突的待发送的上行数据;
与所述SR冲突的所述上行数据的重要等级;
与所述SR冲突的所述上行数据的传输需求;
是否有与所述SR冲突的待发送的侧行数据;
与所述SR冲突的所述侧行数据的传输需求。
通常来说,第一终端在同一时刻可能只能发送上行数据或侧行数据,因此,本申请实施例中,该第一终端可以根据当前是否有与所述SR冲突的待发送的上行数据和/或侧行数据,确定是否触发SR,或者,在有待发送的上行数据和/或侧行数据的情况下,该第一终端还可以进一步结合该待发送的上行数据和/或侧行数据的属性,确定是否触发SR。
结合实施例5~实施例9,说明该实施例4的具体实现。
实施例5:第一终端根据是否有与所述SR冲突的待发送的上行数据,确定是否触发SR。
例如,该第一终端可以在有与所述SR冲突的待发送的上行数据的情况下,确定不触发SR,或者在没有与所述SR冲突的待发送的上行数据的情况下,确定触发SR。
实施例6:第一终端根据与所述SR冲突的待发送的上行数据的重要等级,确定是否触发SR。
