Abstract
本发明实施例提供一种信息传输方法、装置和系统。该方法应用于终端,该终端被配置了用于发送第一类信息的第一类资源池和用于发送第二类信息的第二类资源池,其中,所述方法包括:在所述终端被触发发送信息时,根据所述信息的属性从配置的所述第一类资源池或所述第二类资源池中选择资源;利用选择的资源发送所述信息。通过本发明实施例,能够确保终端不会因为半双工问题而错失对某一类信息的检测,例如用于传输紧急信息的资源检测,提高了资源利用效率,并提高了V2V通信的可靠性。
Description
本发明涉及通信领域,特别涉及一种信息传输方法、装置和系统。
Sidelink(边链路)通信方式是指数据包无需通过核心网和基站,用户1和用户2之间直接建立通信链路,进行通信。在进行边链路通信前,一般会进行发现过程。比如,用户2要通过边链路通信方式发信息给用户1之前,先要发现用户1是否在附近。图1所示为两个UE(用户设备,UE1和UE2)都在基站,例如eNB覆盖下的发现或建立边链路通信的示意图。图2所示为一个UE(UE1)在基站覆盖下,另一个UE(UE2)不在eNB(基站)覆盖下的发现或建立边链路通信的示意图。图3所示为两个UE(UE1和UE2)都不在eNB(基站)覆盖下的发现或建立边链路通信的示意图。
V2X(Vehicle-to-Everything,车辆对任何事物)通信是边链路通信方式的一种,其包含V2V(Vehicle-to-Vehicle,车辆对车辆)通信,V2I(Vehicle-to-Infrastructure,车辆对基础设施)通信,以及V2P(Vehicle-to-Pedestrian,车辆对行人)通信三种类型。图4为这三种类型的通信方式的场景示意图。在V2V场景中,对于两个距离比较近的终端,经过E-UTRAN(Evolved UMTS Terrestrial Radio Access Network,演进的UMTS陆地无线接入网)授权后,可以传输V2V相关的信息。V2V信息可以包括位置、终端属性等信息。V2V信息的大小也应该是可变的。V2V信息的传输可以通过直接传输的形式,即不通过任何基础设施,或者也可以借助RSU(Road Side Unit,路侧单元)等基础设施进行传输。
应该注意,上面对技术背景的介绍只是为了方便对本发明的技术方案进行清楚、完整的说明,并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现,在终端进行边链路传输之前,会被配置资源池。资源池中的SA(Scheduling assignment,调度分配)资源池用于传输PSCCH(Physical Sidelink Control
Channel,物理边链路控制信道)。PSCCH会承载SCI(Sidelink Control Information,边链路控制信息)格式0信息。根据目前的协议,SCI格式0信息会在SA资源池中的两个不同的子帧重复发送两次,如图5所示。其中,在图5所示的场景中,控制信息和数据位于不同的子帧资源,然而,控制信息和数据也可以在同一个子帧中传输。在终端需要发送紧急信息的场景下,需要在很短的时间内,例如20毫秒内能被接收端成功接收。然而,有些接收端会因为半双工的原因,无法成功接收该紧急信息。
为了解决上述问题,本发明实施例提供了一种信息传输方法、装置和系统。

在所述终端被触发发送信息时,根据所述信息的属性从配置的所述第一类资源池或所述第二类资源池中选择用于发送上述信息的资源;

括落入所附权利要求的范围内的全部修改、变型以及等同物。下面结合附图对本发明的各种实施方式进行说明。这些实施方式只是示例性的,不是对本发明的限制。
实施例1
本发明实施例提供了一种信息传输装置,该装置可以应用于终端,例如图1-图3所示场景中的UE1或者UE2,该UE1和UE2可以是图4场景中的车辆。在本实施例中,该终端被配置了用于发送第一类信息的第一类资源池和用于发送第二类信息的第二类资源池。图6是该装置的组成示意图,请参照图6,该装置600包括:选择单元601和发送单元602。
在本实施例中,该选择单元601在该终端被触发发送信息时,根据该信息的属性从配置的上述第一类资源或者上述第二类资源中选择用于发送所述信息的资源。该发送单元602利用选择单元601选择的资源发送上述信息。
在本实施例中,该终端被配置了多个资源池用于传输信息,在图4的V2V通信场景下,这里的终端是指进行V2V通信的车辆,这里的信息是指V2V相关信息。在该场景中,在上述多个资源池中,具有小周期的资源池用于传输紧急信息,其它资源池用于传输非紧急信息,为了方便说明,将紧急信息称为第一类信息,将非紧急信息称为第二类信息,将用于传输第一类信息的资源池称为第一类资源池(包含一个或多个资源池),将用于传输第二类信息的资源池称为第二类资源池(包含一个或多个资源池)。需要说明的是,上述定义是以V2V通信场景为例,本领域技术人员能够清楚,在其它场景下,可以根据需要对第一类信息、第二类信息、第一类资源池、以及第二类资源池进行重新定义,本实施例并不以此作为限制。
在本实施例中,假设有n个资源池配置给该终端,则在配置信息中,可以指示哪个或哪些资源池(称为第一类资源池)用于传输第一类信息,例如前述的紧急信息,而哪个或哪些资源池(称为第二类资源池)用于传输第二类信息,例如前述的非紧急信息。
在本实施例中,对于位于基站覆盖范围内的终端,例如图1场景中的UE1和UE2,或者图2场景中的UE1,上述多个资源池可以通过RRC(Radio Resource Control,无线资源控制)信令配置;对于位于基站覆盖范围外的终端,例如图2场景中的UE2,或者图3场景中的UE1和UE2,上述多个资源池可以预先配置。具体的配置方式不做限制。
在本实施例中,如图6所示,该装置600还可以包括接收单元603,其接收来自应用层的触发命令,该触发命令可以触发该终端的接入层发送上述信息,并且,该触发命令还可以指示上述信息的属性是第一类信息还是第二类信息。在本实施例中,以该终端的应用层发送上述触发命令为例,但本实施例并不以此作为限制,在具体实现过程,上述触发命令的功能也可以通过一个或多个其它信息来实现。在本实施例中,是由应用层触发接入层发送上述信息,同时指示该信息是第一类信息还是第二类信息,也即,上述接收单元603、选择单元601和发送单元602都位于AS(Access Stratum,接入层),一旦接收单元603接收到来自应用层的上述触发命令,选择单元601即可从相应的资源池中选择相应的资源,发送单元603即可利用选择单元601选择的资源发送上述信息。
在本实施例中,在终端被触发发送上述第一类信息时,上述选择单元602可以从配置的第一类资源池中选择用于传输该第一类信息的资源,并且在可选择的子帧资源中选择预定数量的连续的有效子帧作为选择的资源。例如,在终端需要发送的是紧急信息时,该选择单元601可以从专门配置给紧急信息发送的资源池中选择资源,比如在可选择的子帧资源中选择m个连续的有效子帧,用于发送该紧急信息。由此,提高了发送效率,减小了时延,并且提高了通信的可靠性。
在本实施例中,在终端被触发发送上述第二类信息时,上述选择单元602可以从配置的第二类资源池中选择用于传输该第二类信息的资源。例如,在终端需要发送的是非紧急信息时,该选择单元601可以在配置给非紧急信息发送的资源池中选择资源,用于发送非紧急信息。
在本实施例中,第一类资源池中的资源和第二类资源池中的资源可以重叠,也可以不重叠。在不重叠时,该选择单元601可以根据目前的协议选择资源。在重叠时,该选择单元601从配置的第二类资源池中选择的用于传输所述第二类信息的资源在时域上不连续占用所述第一类资源池中预定数量的连续的有效子帧;例如,当选择单元601在用于发送非紧急信息资源池中选择资源时,其选择的资源在时域上不能连续占用用于发送紧急信息资源池中m个连续的有效子帧;从接收端的角度来说,对于用于发送紧急信息的资源池中的子帧资源,其不能连续m个有效子帧都不接收,以确保紧急信息能在至少一个子帧中传输。
下面通过两个实施方式对该选择单元601的选择方式分别进行说明。
在一个实施方式中,该选择单元601在从配置的第二类资源池中选择用于传输上述第二类信息的资源时,避免在该第二类资源池中选择在时域上占用上述第一类资源池中预定数量的连续的有效子帧的资源。也就是说,在本实施方式中,是在资源选择阶段规避上述问题。例如,在进行资源选择阶段,该选择单元601避免在用于发送非紧急信息的资源池中选择在时域上占用用于发送紧急信息资源池的连续m个有效子帧的资源。
在另一个实施方式中,该选择单元601在从配置的第二类资源池中选择了用于传输所述第二类信息的资源后,在所选择的资源在时域上占用了上述第一类资源池中预定数量的连续的有效子帧时,放弃上述预定数量的连续的有效子帧中的一部分。也就是说,在本实施方式中,是在资源选择结束后规避上述问题。在本实施方式中,放弃一部分是指不使用这部分子帧作为上述第二类信息的发送资源。并且在本实施方式中,由终端决定放弃哪些发送资源。
在本实施例中,在通过选择单元601选择好了用于发送上述信息的资源后,发送单元602即可利用选择的资源发送上述信息。具体的发送方式不做限制。
通过本实施例的装置,能够确保终端不会因为半双工问题而错失对某一类信息的检测,例如用于传输紧急信息的资源检测,提高了资源利用效率,并提高了通信的可靠性。

如图7所示,该终端设备700还可以包括:通信模块703、输入单元704、音频处理单元705、显示器706、电源707。值得注意的是,终端设备700也并不是必须要包括图7中所示的所有部件;此外,终端设备70还可以包括图7中没有示出的部
