具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、车与任何事物(vehicle-to-everything，V2X)通信
V2X通信指车辆与外界的任何事物的通信，V2X通信可以包括但不限于：车辆与车辆 (vehicle to vehicle，V2V)通信、车与行人(vehicle to pedestrian，V2P)通信、车与基础设施(vehicle to infrastructure，V2I)通信、车与网络(vehicle to network，V2N)通信。
2、侧行链路(sidelink，SL)
SL是为了支持V2X设备间直接通信而引入的新链路类型。NR SL主要由侧行链路物理控制信道(Physical Sidelink Control Channel，PSCCH)、侧行链路物理共享信道(Physical Sidelink Shared Channel，PSSCH)、侧行链路物理广播信道(Physical Sidelink Broadcast Channel，PSBCH)和侧行链路物理反馈信道(Physical Sidelink Feedback Channel，PSFCH)组成。
为了更好的理解本申请实施例公开的一种确定侧链路时长的方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和多个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定。图1所示的通信系统以包括一个网络设备和四个终端设备为例。其中，终端设备1和终端设备4在网络设备的小区覆盖范围内，终端设备1和终端设备4之间的SL传输的资源是通过网络设备进行配置的，同时终端设备1与网络设备有NR的上下行传输，因为是网络设备进行配置的资源，所以网络设备可以避免覆盖范围内发生资源冲突。同时终端设备2和终端设备3处于网络设备的小区覆盖范围外，终端设备2与终端设备3之间的资源是采取预配置的方式，并且通过感知(sensing)方式进一步筛选可使用的资源。然而，终端设备2与终端设备3的资源池是不同于终端设备1与终端设备4的资源池，也就是说，终端设备2与终端设备3无法得知终端设备1与终端设备4、终端设备1与网络设备之间具体采用的是何种资源，这样的情况下，终端设备2与终端设备3将可能采用与终端设备1与终端设备4之间的NR SL传输和/或终端设备1与网络设备之间的NR传输相同的资源，在空间上形成共存的同频干扰，导致NR SL业务和NR业务的质量下降。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧行链路还可以称为侧链路或直通链路。

下面结合附图对本申请所提供的侧行链路干扰消除的方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种侧行链路干扰消除的方法的流程示意图。如图2所示，该方法适用于第一终端设备，可以包括但不限于如下步骤：
步骤S201：确定第一终端设备的资源占用情况；
其中，第一终端设备的资源占用情况可以包括以下的至少一种情况：第一终端设备已占用的第一资源；以及，第一终端设备将要占用的第二资源。
本申请实施例中，参考图1，第一终端设备可以为处于网络设备的覆盖范围内的终端设备，例如可以为终端设备1或者终端设备4。第一终端设备也可以为网络设备的覆盖范围外的终端设备，例如终端设备2或者终端设备3。
第一终端设备预先配置有资源池，可选地，资源池可以包括第一终端设备可用的空闲资源，第一终端设备可以按照网络配置或预配置的方式从资源池中，确定已占用的第一资源和/或后续待占用的第二资源。其中，后续待占用的第二资源可以按照周期或半周期或者非周期进行占用。
NR系统中，按频域划分时，资源池中的空口资源可以包括资源块(resource block)和子载波(subcarrier)等不同的频率颗粒度；按空间域划分时，NR可以利用多天线传输和接收技术实现同一资源块在不同天线端口(antenna port)/层(layer)上的空分复用。
可以基于网络设备为终端分配资源池，图1所示的通信系统中，终端设备1与终端设备4可以共用一个资源池或者各自有资源池，终端设备2与终端设备3可以共用一个资源池或者各自有资源池，在进行SL传输时，终端设备可以从相应的资源池来分配SL传输的资源，并利用资源进行信息或数据的传输。
其中，第一终端设备已占用的第一资源和/或后续待占用的第二资源包括以下的至少一种：时频域资源、时域资源、频域资源、码域资源；其中，频域资源中可以包括传输时采用的上下行频率和带宽，时域资源中可以包括对资源的占用周期、占用时长、开始时间和结束时间。
V2X终端可提供两种通信接口，分别称为蜂窝通信接口(Uu接口)和直连通信接口(PC5 接口)。终端设备和网络设备可以通过蜂窝通信接口进行通信，终端设备之间可以通过直连通信接口进行通信。
在一些实现中，第一资源可以包括蜂窝通信接口已占用的资源。在另一些实现中，第一资源可以包括直连通信接口已占用的资源。在又一些实现中，第一资源可以包括蜂窝通信接口和直连通信接口已占用的资源。

步骤S202：发送第一终端设备的资源占用情况。
当终端设备都位于基站的小区覆盖范围内，且皆采用网络配置的方式进行初始资源池的规划时，基站会为不同的终端设备配置不同的资源，以避免发生同频干扰。当终端设备都位于基站的小区覆盖范围内时，由于覆盖范围内终端的资源池一致，终端设备还可以通过感知(sensing)方式，在资源选择时对已有的资源池进行进一步的筛选，以规避频率冲突。然而，若存在终端设备位于基站的小区覆盖范围外，此时覆盖范围外终端的NR SL传输的资源池与覆盖范围内终端的资源池不一致，且两者无法相通，导致覆盖范围外的NR SL传输可能采用与覆盖范围内的NR SL传输和NR传输相同的时频资源，造成共存的同频干扰。
在本公开实施例中，第一终端设备的资源占用情况用于指示接收到所述资源占用情况的第二终端设备确定所述第二终端设备通信所采用的的资源。其中，第一终端设备的资源占用情况用于指示所述第二终端设备采用与所述第一终端设备没有冲突的资源进行通信。
在一种可能的实现方式中，可以通过广播的方式发送所述第一终端设备的资源占用情况。广播是一种多点投递的形式，通过广播可以将一个终端设备的信息发送至多个终端设备。本申请实施例中，第一终端设备从自身的资源池中确定出第一资源和/或第二资源后，可以通过广播的方式通知到其他终端设备，以通知其他终端设备该第一终端设备当前使用和/或后续预使用的时频资源。可选地，响应于资源占用情况同时包括第一资源和第二资源，第一终端设备可以对第一资源和第二资源联合广播，即可以在广播消息中同时携带第一资源和第二资源的标识信息。可选地，第一终端设备可以对第一资源和第二资源分别进行广播，即通过不同的广播消息对第一资源和第二资源的标识信息进行广播。当然，如果只发送第一资源或第二资源之中的一个，可以用任何可行的方式进行发送。
本申请实施例提供一种侧行链路干扰消除的方法，通过发送终端设备的资源占用情况，可以使得终端之间能够互相了解相应的时频资源占用情况，以避免同频干扰，达到干扰消除的目的，提高传输质量。

可选地，响应于资源占用情况同时包括第一资源和第二资源，第一终端设备可以对第一资源和第二资源联合广播，即可以在广播消息中同时携带第一资源和第二资源的标识信息。可选地，第一终端设备可以对第一资源和第二资源分别进行广播，即通过不同的广播消息对第一资源和第二资源的标识信息进行广播。当然，如果只发送第一资源或第二资源之中的一个，可以用任何可行的方式进行发送。

在一些实现中，确定第一终端设备的蜂窝通信接口的发射功率，并控制广播功率小于蜂窝通信接口的发射功率。
在另一些实现中，获取为第一终端设备预先配置的功率范围，并控制广播功率处于预先配置的功率范围内，其中，功率范围的最大值小于第一终端设备的蜂窝通信接口的发射功率。
步骤S403：根据广播功率，通过直连通信接口广播资源占用情况。
终端设备之间可以通过直连通信接口进行信息传输，进而可以通过直连通信接口发送广播信息，其中，广播信息用于指示第一终端设备的资源占用情况。广播功率的具体数值可以在确定的功率范围内，根据实际情况进行设置。可选地，广播功率的功率范围可以预先设置，也可以根据第一终端设备的蜂窝通信接口的发射功率进行设置，需要说明的是，为了避免两个接口之间的干扰，应设置直连通信接口的广播功率小于蜂窝通信接口的发射功率。
在一些实现中，距离较远的终端设备与第一终端设备之间可能不存在干扰，此时无需对该终端设备进行广播，则可以降低第一终端设备的广播功率，节省第一终端设备的能耗。
可选地，响应于资源占用情况同时包括第一资源和第二资源，第一终端设备可以对第一资源和第二资源联合广播，即可以在广播消息中同时携带第一资源和第二资源的标识信息。可选地，第一终端设备可以对第一资源和第二资源分别进行广播，即通过不同的广播消息对第一资源和第二资源的标识信息进行广播。当然，如果只发送第一资源或第二资源之中的一个，可以用任何可行的方式进行发送。

步骤S703：根据资源类型，从资源池中确定出目标资源。
若资源池中包括授权频谱资源，则需要确定资源池中是否存在第一资源和/或第二资源，并从除第一资源和/或第二资源之外的剩余资源中确定出目标资源。
由于非授权频谱资源和专用车联网专用频谱资源在固定区域内，是与授权频谱资源相对立的，因此若第二终端设备的资源池仅包括非授权频谱资源和/或车联网专用频谱资源，则确定资源池中未存在使用授权频谱的终端的第一资源和/或第二资源，可以直接从资源池中确定出目标资源。这种方法可以保证位于基站覆盖范围外终端不会对于基站覆盖范围内使用授权频谱的终端产生同频干扰。
其中，目标资源为基于第二终端设备所需的资源量，从剩余资源或资源池中选取的空闲资源。
