本申请涉及无线通信系统中的传输方法和装置，尤其涉及传输延迟较大的系统中资源选择和资源分配的方法和装置。
背景技术
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务定义了4大应用场景组(Use Case Groups)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。目前的V2X系统中，同时支持基于基站配置时频资源用于V2X传输，以及V2X的发送端通过感知测量(Sensing Measurement)确定时频资源用于V2X传输。
与此同时，为了能够适应多样的应用场景和满足不同的需求，在3GPP RAN#75次全会上还通过了NR下的非地面网络(NTN，Non-Terrestrial Networks)的研究项目，该研究项目在R15版本开始。在3GPP RAN#79次全会上决定开始研究NTN网络中的解决方案，然后在R16或R17版本中启动WI对相关技术进行标准化。
发明内容
NTN网络具有覆盖广的优势，当NTN结合V2X技术时，NTN网络能够为地面基站覆盖不到的地理位置配置用于V2X传输的时频资源，随后V2X终端间基于现有的sensing的方式确定实际传输的时频资源。然而，与现有地面蜂窝网相比，NTN网络存在远大于地面基站的路径延迟，且针对卫星的上行发送功率值也会较大，进而需要重新考虑蜂窝链路对V2X链路传输的干扰以及对应的干扰协调的方法。
基于上述新的应用场景和需求，本申请公开了一种解决方案，需要说明的是，在不冲突的情况下，本申请的第一节点和第三节点的实施例和实施例中的特征可以应用到基站中，且本申请中的第二节点的实施例和实施例中的特征可以应用到终端中。与此同时，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
本申请公开了一种被用于无线通信的第一节点中的方法，其特征在于包括：
接收第一信令，所述第一信令被用于指示第一时间单元集合；
发送第二信令，所述第二信令被用于指示第一时间间隔；
接收第三信令，所述第三信令指示第一多载波符号集合和第一调度信息；
当第二多载波符号集合属于所述第一时间单元集合时，放弃在所述第一多载波符号集合中进行无线发送；当第二多载波符号集合不属于所述第一时间单元集合时，在所述第一多载波符号集合中发送第一信号；
其中，所述第一调度信息被应用于所述第一信号；所述第二多载波符号集合中的多载波符号与所述第一多载波符号集合中的多载波符号一一对应；所述第二多载波符号集合中的任一多载波符号与所述第一多载波符号集合中对应的多载波符号之间的时间间隔是所述第一时间间隔。
作为一个实施例，上述方法的原理在于：目前V2X系统中，传输延迟往往不会超过一个多载波符号的持续时间，进而只要终端将发送时间和基站对齐，参考基站时序的不同时隙中的V2X传输和Uu口上行传输之间不会产生干扰；而NTN系统中，由于传输延迟较大，达到多个甚至几十个毫秒的级别；进而当一个NTN的终端发送上行时，即使从基站侧看V2X与NTN配置在不同的时隙中，NTN的发送也会偏移到V2X子帧中，进而导致 Uu链路对V2X的干扰。
作为一个实施例，上述方法的好处在于：所述第一时间间隔对应第一节点到NTN基站之间的延迟，所述第二多载波符号集合对应因为延迟造成的Uu口上在所述第一多载波符号集合中传输的无线信号所能够扩散到的时域资源；进而当所述第二多载波符号集合与所述第一时间单元集合重合时，意味着Uu上的传输会对V2X产生影响，进而需要避免Uu上的传输。
作为一个实施例，上述方法的另一个好处在于：通过第二信令将所述第一时间间隔发送给NTN的基站，当所述第一节点针对NTN基站的上行发送会潜在的对配置的第一时间单元集合中的V2X传输产生干扰时，NTN基站避免在所述第二多载波符号集合中调度所述第一节点。

其中，所述第一调度信息被应用于所述第一信号，所述第二多载波符号集合中的多载波符号与所述第一多载波符号集合中的多载波符号一一对应；所述第二多载波符号集合中的任一多载波符号与所述第一多载波符号集合中对应的多载波符号之间的时间间隔是所述第一时间间隔。

作为一个实施例，上述方法的好处在于：通过sensing触发第二信令的发送，进而仅在检测到周边存在V2X传输时，才会指示基站通过调度的方式规避对V2X传输的干扰。
