Description

时频资源确定方法及装置 技术领域
本发明实施例涉及通信技术领域，尤其涉及一种时频资源确定方法及装置。
背景技术
D2D是一种端到端直接通信的技术，与传统的蜂窝通信技术相比，D2D可以不需要通过基站的中转就可以实现终端到终端之间的通信。在D2D通信过程中，基站可以为终端进行资源的配置、调度和协调等，用以辅助终端与终端之间可以直接进行通信。
车联网系统就是D2D通信技术应用中的很好体现，由于汽车网络中通过车车通信或者车与路边单元之间的通信可以提高道路交通的安全性、可靠性，进而可以提升交通通行效率，因此，近年车联网系统越来越受到人们的关注。在车联网系统中，为保证车辆安全行驶，车与车之间需要周期性的交互信息，例如车辆的位置、速度和状态等信息，车辆可以将这些信息通过单跳的方式广播给周围车辆，以提高车辆在行驶过程中的安全性。在车联网系统中，包括车与车(Vehicle-to-Vehicle，V2V)，车与基础设施(Vehicle-to-Infrastructure，V2I)之间的通信，车与人(Vehicle-to-Pedestrian，V2P)，以及车与网络(Vehicle-to-Network，V2N)之间的通信等等。
目前的车联网系统，主要借助于蜂窝网络来实现车与车，或者车与其他终端之间的通信，以V2V为例，这种通信方式可以有两种：第一种，车辆采用广播的方式向周围的其他车辆发送自身的状态信息，不需要基站进行数据的转发，如图1所示；第二种，车辆间的信息通过基站转发，车辆首先将状态信息发送给基站，基站再通过单播或者广播的方式将数据发送给其他车辆，如图2所示。其中，图1和图2中的V1～V4是指车辆。
车联网系统可以在蜂窝系统的载频上运行，此时车联网系统和蜂窝系统会在该载频上同时存在。由于车联网系统分为小区覆盖范围外(Out Of Coverage，OOC)和IC(In Coverage，小区覆盖范围内)两种场景，在IC场景中，车联网系统可以采用基站(Evolved NodeB，eNodeB)或全球卫星导航系统(Global  Navigation Satellite System，GNSS)作为同步源，在OOC场景中，车联网系统通常采用GNSS作为同步源。由于上述两种同步源之间存在时间差，在IC中的车辆同时与基站、OCC中的车辆进行通信时，会导致车联网系统会对蜂窝系统产生通信干扰，进而造成IC中的车辆无法同时与基站、OCC中的车辆进行正常通信。
发明内容

具体实施方式
下面结合附图，对本发明的实施例进行描述。
图3为小区内的终端100分别与小区外的终端200、基站300通信时的场景示意图，其中，小区内的终端100通过蜂窝系统与基站300通信，采用的是基站的定时时间，即eNB timing；小区内的终端100通过D2D系统与小区外的终端200通信，采用的是卫星400的定时时间，即GNSS timing。由于终端100与终端200通信时，采用的通信资源是由基站通过分配传输资源池，为D2D系统分配特定时频资源。示例性的，如图4所示，图4为终端100分别与基站300、终端200之间的通信资源，D表示下行子帧、U表示上行子帧、V表示终端100与终端200之间的通信子帧、S表示蜂窝系统中的特殊子帧。其中，终端100与终端200之间通过无线帧中的V子帧进行数据传输。
蜂窝系统采用基站的定时时间，即eNB timing；D2D系统采用的是卫星的定时时间。由于基站的定时时间和卫星的定时时间有一定的定时偏差，示例性的，在终端100通过蜂窝系统获取基站300发送的通信消息时，同时终端100通过D2D系统获取终端200发送的通信消息时，由于定时偏差的原因，会导致D2D通信与蜂窝通信之间产生通信干扰。如图5所示，A采用的是eNB timing，B采用的是GNSS timing，由于二者的定时偏差，导致D2D系统通信的时频资源的第二个V子帧与蜂窝系统中的时频资源第一个U子帧发生重叠，导致终端100不能同时正确获取基站300和终端200发送的通信数据，造成蜂窝系统和D2D系统之间的通信干扰。
因此，为了解决因定时偏差导致蜂窝系统和D2D系统之间通信的相互干扰问题，本发明实施例提供了一种时频资源确定方法。
结合图3所示，在终端100分别与基站300、终端200的通信过程中，终端100通过蜂窝系统与基站300进行通信，终端100通过D2D系统与终端200进行通信。终端200根据卫星400的定时时间确定第一时频资源，该第一时频资源用 于终端200与终端200之间的通信，
终端200根据基站300的定时时间确定第二时频资源，该第二时频资源用于终端200与基站300之间的通信。
由于基站300的定时时间和卫星400的定时时间有一定的偏差，导致第一时频资源和第二时频资源在时域具有部分或全部重叠，如图6所示。示例性，本实施例中的第一时频资源可以是图6中B1对应V子帧，第二时频资源可以是图6中A1对应U子帧，该实施例中，第一时频资源和第二时频资源发生了部分重叠。
为了防止D2D系统干扰蜂窝系统的通信，即避免终端100通过第一时频资源与终端200通信，造成第一时频资源和第二时频资源发生部分或全部重叠，终端100不将第一时频资源用于与终端200进行通信。
另外，终端200还可以获取终端100发送的定时偏差，并获取卫星400的定时时间，根据定时偏差和卫星400的定时时间，计算出基站300的定时时间。终端200根据基站300的定时时间和卫星400的定时时间，确定图6中具有部分或全部重叠的第一时频资源和第二时频资源，即图6中A1和B1分别对应的子帧，终端200不将第一时频资源用于与终端100进行通信，即终端200不使用B1对应的V子帧与终端100进行通信，即将第一时频资源作为预留资源，避免D2D系统干扰蜂窝系统的通信，造成终端100不能正确获取基站300发送的数据。
在本发明提供的又一实施例中，结合图3，在第一时频资源与第二时频资源发生部分或全部重叠时，由基站300重新确定终端100与终端200之间进行通信的第三时频资源，具体的：
基站300根据自身的定时时间，确定基站300与终端100之间通信的第二时频资源。基站300根据卫星400的定时时间，确定终端100与终端200之间进行通信的第三时频资源。
其中，第二时频资源与第三时频资源不重叠。基站300将包括第三时频资源用于终端100与终端200之间进行通信的资源配置信息发送给终端100，以便终端100根据该配置信息，使用第三资源与终端200进行通信。由于第三时频资源与第二时频资源不重叠，使得D2D系统通信不会干扰蜂窝系统的通信。
另外，基站300通过系统信息块(System Information Block，SIB)、下行控制信息(Downlink Control Information，DCI)或无线资源控制(Radio Resource  Control，RRC)向终端100发送资源配置信息。
终端100获取基站300发送的资源配置信息，该配置信息用于指示将第三时频资源用于终端100与终端200之间进行通信。
终端100根据该配置信息，通过第三时频资源与终端200进行通信。
其中，第三时频资源是由基站300根据自身的定时时间确定的。第二时频资源是基站300根据卫星400的定时时间确定，第三时频资源与第二时频资源不重叠。
另外，在其他实施例中，终端200还可以检测是否有服务小区外的终端(如终端200)与其通信，如果没有，基站300可以配置服务器小区内的终端采用基站作为同步源，即采用终端300的定时时间，避免蜂窝系统和D2D系统之间因定时偏差带来的通信干扰。
需要说明的是，下述实施例中的第一定时，相当于上述实施例中卫星400的定时时间，即GNSS定时时间；下述中的第二定时，相当于上述实施例中基站的定时时间。
为了解决因基站和GNSS之间的定时偏差带来的蜂窝系统与D2D系统之间产生通信干扰，并详述上述执行流程，在本发明提供的又一实施例中，结合上述各实施例，还提供了一种时频资源确定方法，该方法应用于位于服务器小区内的第一终端，如图7所示，该方法可以包括如下步骤：
在步骤S710中，第一终端确定第一时频资源。
其中，第一时频资源是第一终端根据第一定时确定的，第一时频资源是用于第一终端与第二终端进行通信的时频资源。
在步骤S720中，第一终端确定第二时频资源。
其中，第二时频资源是第一终端根据第二定时确定的，第二时频资源是用于第一终端与基站进行通信的时频资源。
在步骤S730中，第一终端确定第一时频资源与第二时频资源在时域具有部分或全部重叠。
在步骤S740中，第一终端不将第一时频资源用于与第二终端进行通信。
其中，第一定时是根据全球卫星导航系统GNSS获得的定时时间；第二定时 是根据基站获得的定时时间。第一时频资源和第二时频资源分别包括一个或者多个子帧。
结合上述实施例，这里的第一终端相当于图3中的终端100，第二终端相当于终端200。在第一终端采用第一时频资源通过D2D系统与第二终端通信、第一终端采用第二时频资源通过蜂窝系统与基站通信过程中，由于第一时频资源与第二时频资源具有部分或者全部重叠，终端100并不使用第一资源与终端200进行通信，使得D2D系统的通信不会干扰到蜂窝系统的通信，即蜂窝系统与D2D系统的通信互不干扰，从而在第一时频资源与第二时频资源部分或全部重叠时，避免造成D2D系统会对蜂窝系统的通信干扰，使得第一终端不能正常进行通信的问题。
为了使第二终端不使用第一时频资源与第一终端进行通信，作为图7方法的细化，在本发明的另一实施例中，如图8所示，该方法还可以包括如下步骤：
在步骤S750中，第一终端向第二终端发送指示信息。
其中，该指示信息用于指示不将第一时频资源用于第一终端与第二终端之间进行通信。
第一终端可以通过物理侧行链路广播信道(Physical Sidelink Broadcast Channel，PSBCH)向所述第二终端发送所述指示信息。
第一终端向第二终端发出用于指示不将第一时频资源用于第一终端与第二终端之间进行通信的指示信息，从而可以避免D2D系统干扰蜂窝系统的正常通信。
为了使第二终端不使用第一时频资源与第一终端进行通信，作为图7方法的细化，在本发明的另一实施例中，如图9所示，该方法还可以包括如下步骤：
在步骤S760中，第一终端将定时偏差发送给第二终端。
其中，定时偏差是第一定时和第二定时之间的定时偏差。
第一终端将定时偏差发送给第二终端，以使第二终端根据定时偏差以及第一定时确定出第二定时，并且根据第一定时和第二定时确定第一时频资源与第二时频资源有部分或全部重叠，从而避免使用第一时频资源与第一终端进行通信，防止D2D系统的通信干扰蜂窝系统的通信。
为了使第二终端不使用第一时频资源与第一终端进行通信，在本发明的另一实施例中，如图10所示，在第二终端侧的执行流程，包括如下步骤：
在步骤S781中，第二终端根据接收第一终端发送的定时偏差。
在步骤S781中，第二终端根据定时偏差和第一定时，确定出第二定时，其中，第一时频资源是第一终端根据第一定时确定的，第一时频资源是用于第一终端与第二终端进行通信的时频资源，第二时频资源是第一终端根据第二定时确定的，第二时频资源是用于第一终端与基站进行通信的时频资源。
在步骤S781中，第二终端根据第一定时和第二定时，确定第一时频资源与第二时频资源在时域具有部分或全部重叠。
在步骤S781中，第二终端不将第一时频资源用于与第一终端进行通信。
其中，第一定时是根据全球卫星导航系统GNSS获得的定时时间，第二定时是根据基站获得的定时时间。第一时频资源和第二时频资源分别包括一个或者多个子帧。
第二终端还可以获取第一终端发送的定时偏差，并获取GNSS的定时时间，根据定时偏差和GNSS的定时时间，计算出基站的定时时间。第二终端根据基站的定时时间和GNSS的定时时间，确定图6中具有部分或全部重叠的第一时频资源和第二时频资源，即图6中A1和B1分别对应的子帧，第二终端不将第一时频资源用于与第一终端进行通信，即第二终端不使用B1对应的V子帧与第一终端进行通信，即将第一时频资源作为预留资源，避免D2D系统干扰蜂窝系统的通信，造成第一终端不能正确获取基站发送的数据。
在本发明提供的又一实施例中，结合上述各实施例，还提供了一种时频资源确定方法，该方法应用于位于服务器小区内的第一终端，如图11所示，该方法可以包括如下步骤：
在步骤S810中，第一终端获取基站发送的资源配置信息。
其中，资源配置信息用于指示将第三时频资源用于第一终端与第二终端之间进行通信。
在步骤S820中，第一终端根据资源配置信息，将第三时频资源用于与第二终端进行通信。
其中，第三时频资源与第二时频资源不重叠。第三时频资源是基站根据第一定时确定的，第三时频资源是用于第一终端与第二终端进行通信的时频资源。
第二时频资源是基站根据第二定时确定的，第二时频资源是用于第一终端与基站进行通信的时频资源。第一定时是根据全球卫星导航系统GNSS获得的定时时间；第二定时是根据基站获得的定时时间。
该实施例主要是在基站通过配置D2D资源池中的时频资源，并将配置信息发送给第一终端，使得终端采用第三时频资源通过D2D系统与第二终端进行通信，而第一终端采用第二时频资源与基站进行通信，并且第三时频资源与第二时频资源不重叠。避免D2D系统与蜂窝系统之间的通信干扰。
为了使第二终端使用与第二时频资源不重叠的第三时频资源与第一终端进行通信，作为图11方法的细化，在本发明的另一实施例中，如图12所示，还可以包括如下步骤：
在步骤S830中，第一终端向第二终端发送指示信息，指示信息用于指示将第三时频资源用于第一终端与第二终端之间进行通信。
其中，第一终端通过侧行链路广播信道PSBCH向第二终端发送指示信息。
第二时频资源和第三时频资源分别包括一个或者多个子帧。
第一终端向第二终端发出用于指示将第三时频资源用于第一终端与第二终端之间进行通信的指示信息，从而可以避免D2D系统干扰蜂窝系统的正常通信。
在本发明提供的又一实施例中，结合上述各实施例，还提供了一种时频资源确定方法，该方法应用于基站，如图13所示，该方法可以包括如下步骤：
在步骤S910中，基站确定第三时频资源。

在步骤S920中，基站确定第二时频资源。
其中，第二时频资源是基站根据第二定时确定的，第二时频资源是用于第一终端与基站进行通信的时频资源。
在步骤S930中，基站确定第三时频资源与第二时频资源在时域不重叠。
在步骤S940中，基站生成资源配置信息，并将资源配置信息发送给第一终端。
其中，配置信息用于指示将第三时频资源用于第一终端与第二终端之间进行通信。
另外，基站通过SIB、DCI或RRC向终端发送资源配置信息。
