信号传输方法及通信装置
本申请要求于2021年04月30日提交国家知识产权局、申请号为202110482926.9、发明名称为“信号传输方法及通信装置”的中国专利申请的优先权，以及要求于2021年08月24日提交国家知识产权局、申请号为202110975580.6、发明名称为“信号传输方法及通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种信号传输方法及通信装置。
背景技术
雷达通信一体化技术能够同时实现雷达探测与数据传输的功能。即，网络设备可以既发送雷达探测信号，以实现雷达探测功能，又发送同步信号块(synchronization signal block，SSB)信号，以使终端设备与网络设备之间同步，实现数据传输功能。
然而，若雷达探测信号的传输资源与SSB信号的传输资源在时域上重叠，即网络设备同时发送雷达探测信号和SSB信号，则不同信号之间容易产生干扰，系统通信效率低。
发明内容
本申请实施例提供一种信号传输方法及通信装置，能够避免第一信号(如雷达探测信号)和同步信号块SSB信号之间的干扰，提高系统通信效率。
为达到上述目的，本申请实施例采用如下技术方案：
第一方面，本申请实施例提供一种信号传输方法，该方法的执行主体可以是网络设备，也可以是应用于网络设备中的芯片。下面以执行主体是网络设备为例进行描述。该方法包括：网络设备确定第一资源，其中，第一资源和第二资源在时域上不重叠，第二资源用于发送同步信号块SSB信号，第一资源与第二资源存在对应关系。然后，网络设备在第一资源上传输至少一个第一信号，其中，第一信号用于探测目标的属性。其中，第一资源与第二资源存在对应关系，是指，第一资源与第二资源在资源位置上存在对应关系。
也就是说，网络设备确定的第一资源是时域上与第二资源不重叠的资源，两者之间在资源位置上存在对应关系。如此，第一信号与SSB信号的发送时间不同，以使第一信号与SSB信号不发生碰撞，互不干扰，从而提升系统通信效率。
在一种可能的设计中，在目标时长内，第一资源不包含第三资源中与SSB信号的候选位置重叠的资源。其中，目标时长由第二资源所在的至少一个时隙构成，第三资源是基于第一信号的传输周期确定的。
也就是说，第一资源是第三资源中除去与SSB信号的候选位置重叠的资源，所以，网络设备不同时传输第一信号和SSB信号，从而避免第一信号与SSB信号发生碰撞，以提高系统通信效率。
在一种可能的设计中，当第三资源中部分资源与SSB信号的候选位置重叠，则 第一资源至少包括：将第三资源中与SSB信号的候选位置重叠的资源提前或延后至少一个时域符号之后的资源。
也就是说，在第三资源中部分资源与SSB信号的候选位置重叠的情况下，移动(如提前或延后)与SSB信号的候选位置重叠的资源，以避免网络设备同时传输第一信号和SSB信号。
在一种可能的设计中，在目标时长内，第一资源由第三资源中与SSB信号的候选位置不重叠的资源构成。
也就是说，构成第一资源的资源均与SSB信号的候选位置不重叠，从而避免网络设备同时传输第一信号和SSB信号。
在一种可能的设计中，第一资源是基于第二资源确定的。也就是说，第一资源是以第二资源为基准，进行调整后的资源，以使第一资源与第二资源在时域上不重叠。
在一种可能的设计中，第一间隔与第二间隔不同。其中，第一间隔是目标时长内，至少一个第一信号中相邻两个第一信号之间的间隔。第二间隔是目标时长外，至少一个第一信号中相邻两个第一信号之间的间隔。目标时长是由第二资源所在的至少一个时隙构成。
也就是说，目标时长内相邻两个第一信号之间的时间间隔，与目标时长外相邻两个第一信号之间的时间间隔不同。
在一种可能的设计中，第一间隔为多个，且多个第一间隔的时间长度相同。其中，第一间隔为多个，是指：网络设备在目标时长内传输多个第一信号，每相邻两个第一信号之间存在一个第一间隔。如此，第一个间隔的数量为多个。换言之，第一信号在目标时长内仍保持等间隔传输。
在一种可能的设计中，在目标时长内，第一资源包括索引值为第一预设值的时域资源单元。
在一种可能的设计中，时域资源单元为时域符号，第一预设值包括以下其中一项：0、1、12、或13。
也就是说，在传输SSB信号的子载波间隔为120kHz的情况下，以单个时隙为粒度，第二资源始终不占用的时域符号索引如下：0、1、12、和13，所以，第一资源在目标时长内占用一个时隙内的符号0、1、12、或13中的一个，与第二资源在时域上不重叠，从而避免第一信号与SSB信号发生碰撞。
在一种可能的设计中，第一间隔为多个，且多个第一间隔中至少两个的时间长度不同。也就是说，第一信号在目标时长内可以不保持等间隔传输。
在一种可能的设计中，在目标时长内，第一资源包括索引值为第二预设值的时域资源单元。
在一种可能的设计中，时域资源单元为时域符号，且时域符号分布于两个连续的时隙，第二预设值包括以下至少三项：0、1、2、3、12、13、14、15、24、25、26、或27。其中，第二预设值中的任意两项之间的差值大于或等于第三预设值。
也就是说，每连续的两个时隙上至少存在三个第一资源。换言之，每两个时隙至少传输三个第一信号，提升了第一信号的时域密度，有利于提高雷达探测精度。并且，第二预设值中的任意两项之间的差值大于或等于第三预设值，也就使得第一资源在时 域上是非连续的，从而在一定程度上保证了第一信号均匀分布。
在一种可能的设计中，时域资源单元为时域符号，且时域符号分布于两个连续的时隙，第二预设值包括：3、13、24，或第二预设值包括：13、20、27。
在一种可能的设计中，第二资源是基于第一资源确定的。也就是说，第二资源是以第一资源为基准，进行调整后的资源，以使第一资源与第二资源在时域上不重叠。
在一种可能的设计中，第一间隔与第二间隔相同。其中，第一间隔是目标时长内，至少一个第一信号中相邻两个第一信号之间的间隔。第二间隔是目标时长外，至少一个第一信号中相邻两个第一信号之间的间隔。目标时长是由SSB信号的候选位置所在的至少一个时隙构成。
也就是说，无论在目标时长内，还是在目标时长外，第一信号保持相同的传输周期。
在一种可能的设计中，在目标时长内，第二资源包括索引值为第四预设值的时域资源单元，第四预设值满足如下公式：
Figure PCTCN2022087421-appb-000001
其中，M表示第四预设值，N为整数，且0≤N≤27，k为正整数。
也就是说，在第一信号的传输周期为7个时域符号的情况下，第一资源的时域符号索引满足：7*k-1。在N遍历28个整数(即从0至27)的过程中，承载SSB信号的时域符号索引不等于第一资源的时域符号索引，从而避免第一资源与第二资源在时域上重叠。
在一种可能的设计中，在目标时长内，第二资源包括索引值为第四预设值的时域资源单元，第四预设值满足如下公式：
Figure PCTCN2022087421-appb-000002
其中，M表示第四预设值，N的取值包括以下至少两项：0、1、2、7、8、9、14、15、16、21、22、或23。
在一种可能的设计中，N的取值包括：2、8、16、或22。
在一种可能的设计中，本申请实施例信号传输方法还包括：网络设备向终端设备发送指示信息，其中，指示信息指示所述索引值。
也就是说，在第一资源的资源位置保持不变，且第二资源是基于第一资源确定的情况下，网络设备先为终端设备指示第二资源的索引值，以使终端设备在指示信息指示的资源位置上接收SSB信号。
第二方面，本申请实施例提供一种信号传输方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备中的芯片。下面以执行主体是终端设备为例进行描述。该方法包括：终端设备接收指示信息。其中，指示信息指示第二资源的位置信息。然后，终端设备在第二资源上，接收同步信号块SSB信号。
也就是说，在第一资源的资源位置保持不变，且第二资源是基于第一资源确定的 情况下，网络设备先为终端设备指示第二资源的位置信息，终端设备在指示信息指示的资源位置上接收SSB信号。
在一种可能的设计中，第二资源的位置信息包括第四预设值。其中，第四预设值包括第二资源的时域资源单元的索引值，且第四预设值满足如下公式：

其中，M表示第四预设值，N为整数，且0≤N≤27，k为正整数。

也就是说，网络设备确定的第一资源是时域上与第二资源重叠，但频域上与第二资源不重叠的资源，两者之间在资源位置上存在对应关系。如此，第一信号与通信信号通过不同的频域资源发送，以使第一信号与通信信号不发生碰撞，互不干扰，从而提升系统通信效率。
在一种可能的设计中，第一资源包括系统带宽中频率最小的X个频域资源单元，X为正整数。或者，第一资源包括系统带宽中频率最大的Y个频域资源单元，Y为正整数。
在一种可能的设计中，本申请实施例信号传输方法还包括：网络设备向终端设备发送第一指示信息。其中，第一指示信息指示以下两项：
第一项，第一带宽与通信信号的带宽之和小于或等于系统带宽。其中，第一带宽是第一信号与通信信号在时域上重叠时的带宽。也就是说，在第一信号配置的带宽为系统带宽的情况下，网络设备为终端设备指示第一信号与通信信号重叠时的第一带宽，以使终端设备基于指示信息指示的第一带宽来接收第一信号。
第二项，第二带宽等于系统带宽。其中，第二带宽是第一信号与通信信号在时域上不重叠时的带宽。也就是说，在第一信号配置的带宽为系统带宽的情况下，网络设备为终端设备指示第一信号与通信信号不重叠时的第二带宽，以使终端设备基于指示信息指示的第二带宽来接收第一信号。
在一种可能的设计中，本申请实施例信号传输方法还包括：网络设备向终端设备发送第二指示信息。其中，第二指示信息指示以下两项：第一信号的带宽等于系统带 宽，网络设备在第二资源上未发送第一信号，以使终端设备获知第一信号的带宽，且无需在第二资源上接收第一信号。
在一种可能的设计中，第一资源包括系统带宽中除第二资源之外的频域资源单元。
在一种可能的设计中，本申请实施例信号传输方法还包括：网络设备向终端设备发送第三指示信息。其中，第三指示信息指示第一资源的位置信息，以使终端设备获取第一资源的资源位置。
在一种可能的设计中，第三指示信息还指示第四资源的位置信息，其中，第四资源和第二资源在时域上不重叠，第四资源用于传输第一信号，以使终端设备获取第四资源的资源位置。
在一种可能的设计中，第一信号上承载有通信信息。也就是说，网络设备通过第一信号向终端设备发送通信信息。

在新无线(new radio，NR)中，网络设备周期性地发送SSB信号。一个SSB信号包括同步信号(synchronization signal，SS)和物理广播信道(physical broadcast channel，PBCH)。其中，SS包括主同步信号(primary synchronization signal，PSS)和辅同步信号(secondary synchronization signal，SSS)。终端设备通过PSS和SSS识别小区以及和小区进行同步。终端设备通过PBCH获得最基本的系统信息，例如系统帧号、帧内定时信息等。终端设备成功接收SSB信号是其接入该小区的前提。
如图1所示，在时域上，一个SSB信号占4个时域符号，如图1中时域符号编号为0至3的4个时域符号。在频域上，一个SSB信号占20个资源块(resource block，RB)，也就是240个子载波，在这20个RB内，子载波编号为0～239。PSS位于时域符号0的中间的127个子载波上，SSS位于时域符号2的中间的127个子载波上。为了保护PSS和SSS，分别有不同的保护子载波被设为0，也就是保护子载波不用于承载信号，在SSS两侧分别留了8个子载波和9个子载波用于作为保护带子载波，如图1中的SSS两侧的空白区域就是保护子载波。PBCH占用时域符号1和时域符号3的全部子载波，以及占用时域符号2的全部子载波中除了SSS所占用的子载波之外的剩余的子载波中的一部分子载波(即剩余的子载波中除了保护子载波之外的子载波)。
一个SSB信号关联一个索引(index)，以标识该SSB信号。在一个半帧中，一个SSB信号的索引为0时，该索引标识的SSB信号是该半帧中的首个SSB信号，一个SSB信号的索引为1时，该索引标识的SSB信号是该半帧中的第二个SSB信号，其它可以此类推。示例性的，在图2a中，索引0标识的SSB信号为半帧中的首个SSB信号，所占时域符号的索引为4至7。索引1标识的SSB信号为半帧中的第二个SSB信号，所占时域符号的索引为8至11。索引2标识的SSB信号为半帧中的第三个SSB信号，所占时域符号的索引为16至19。索引3标识的SSB信号为半帧中的第四个SSB信号，所占时域符号的索引为20至23。在图2b中，索引0标识的SSB信号为半帧中的首个SSB信号，所占时域符号的索引为4至7，索引1标识的SSB信号为半帧中的第二个SSB信号，所占时域符号的索引为16至19。索引上连续的两个SSB信号在时域上可以连续，如图2a中索引0标识的SSB信号和索引1标识的SSB信号。索引上连续的两个SSB信号在时域上也可以不连续，如图2b中索引0标识的SSB信号和索引1标识的SSB信号。
需要说明的是，若传输SSB信号的子载波间隔(subcarrier spacing，SCS)不同，则SSB信号的候选位置也不一样。下面，基于不同的子载波间隔，分5种情况(case)对SSB信号的候选位置进行介绍：
情况A，在SCS为15kHz的情况下，SSB信号的时域符号索引满足：
{2，8}+14*n    公式(1)
其中，在没有共享频谱信道接入的情况下，若载波频率小于或等于3GHz，则n＝0，1，若频率范围(frequency range)大于3GHz，则n＝0，1，2，3。在有共享频谱信道接入的情况下，n＝0，1，2，3，4。
示例性的，在有共享频谱信道接入的情况下，SSB信号的候选位置最多有10个。在n＝0的情况下，对应两个SSB信号的候选位置。其中，第一个候选位置的首个时域符号索引为2，第二个候选位置的首个时域符号索引为8。
情况B，在SCS为30kHz的情况下，SSB信号的时域符号索引满足：
{4，8，16，20}+28*n    公式(2)
其中，若载波频率小于或等于3GHz，则n＝0，若频率范围大于3GHz，则n＝0，1。
情况C，在SCS为30kHz的情况下，SSB信号的时域符号索引满足：
{2，8}+14*n     公式(3)
其中，在没有共享频谱信道接入的情况下，对于配对的频谱而言，若载波频率小于或等于3GHz，则n＝0，1，若频率范围大于3GHz，则n＝0，1，2，3。对于无配对的频谱而言，若载波频率小于1.88GHz，则n＝0，1，若频率范围大于或等于1.88GHz，则n＝0，1，2，3。在有共享频谱信道接入的情况下，n＝0，1，2，3，4，5，6，7，8，9。
情况D，在SCS为120kHz的情况下，SSB信号的时域符号索引满足：
{4，8，16，20}+28*n    公式(4)
其中，若载波频段属于频率范围2(frequency range 2，FR2)，则n＝0，1，2，3，5，6，7，8，10，11，12，13，15，16，17，18。
情况E，在SCS为240kHz的情况下，SSB信号的时域符号索引满足：
{8，12，16，20，32，36，40，44}+56*n     公式(5)
其中，若载波频段属于FR2，则n＝0，1，2，3，5，6，7，8。
需要说明的是，在终端设备与网络设备之间实现同步的过程中，终端设备按照协议规定，在上述SSB信号的候选位置上接收来自网络设备的SSB信号，网络设备无需为终端设备指示SSB信号的候选位置。上述公式(1)至公式(5)，均指示SSB信号的候选位置的首个时域符号的索引。
2、频率范围
在第三代合作伙伴计划3GPP协议中，第五代移动通信技术(the 5th generation mobile communication technology，5G)网络的总体频谱资源可以分为以下两个频率范围，如下表1所示：
表1
频率范围名称 频率范围
FR1 410MHz–7125MHz
FR2 24250MHz–52600MHz
应理解，上述FR1、FR2的命名不应对本申请构成任何限定。本申请并不排除在未来的协议中定义其他名称来表示相同或相似含义的可能。
FR1：Sub 6G频段，换句话说，低频频段，为5G网络的主用频段。在FR1中，3GHz以下的频率可以称为Sub 3G，其余波段可以称为C-band。应理解，FR1对应的频率范围可以对应于如表1所示的410MHz–7125MHz，但不限于此，本申请并不排除在未来的协 议中定义其他的范围来表示相同或相似含义的可能。
FR2：6G以上的毫米波，换句话说，高频频段，为5G网络的扩展频段，频谱资源丰富。应理解，FR2对应的频率范围可以对应于如表1所示的24250MHz–52600MHz，但不限于此，本申请并不排除在未来的协议中定义其他的范围来表示相同或相似含义的可能。
3、雷达探测
雷达装置发射雷达探测信号，雷达探测信号遇到目标物体之后发生漫反射，形成回波信号。雷达装置接收经过目标物体反射的回波信号，基于雷达探测信号和回波信号从而实现目标物体探测，如确定目标物体的距离、方位、高度、速度、姿态、形状等特征量。其中，雷达装置，也可以称为雷达、探测器、或雷达探测装置等。
雷达探测，也可以描述为雷达感知，多应用于交通探测、气象监测等场景。但是如果单独使用雷达对广范围探测，会有较高成本。因此，将无线通信丰富的频谱资源与雷达探测进行融合，可支持连续组网等大规模需求。
4、雷达通信一体化
雷达通信一体化，是指通过共用硬件设备来同时实现雷达探测与数据传输的功能。在雷达探测功能融合到网络设备后，网络设备既发送雷达探测信号，以实现雷达探测功能，又发送SSB信号，以使终端设备与网络设备之间实现同步，从而传输数据。
然而，在雷达探测信号的传输资源与SSB信号的传输资源重叠的情况下，即网络设备同时发送雷达探测信号和SSB信号，不同信号之间容易产生干扰，影响雷达探测信号和SSB信号的正常传输，系统通信效率低。
有鉴于此，本申请实施例提供一种信号传输方法，本申请实施例信号传输方法适用于各种通信系统。本申请实施例提供的信号传输方法可以应用于长期演进(long term evolution，LTE)系统，或者5G网络，或者其他类似的网络中，或者未来的其它网络中。图3为可适用于本申请实施例信号传输方法的通信系统的架构示意图，该通信系统包括网络设备301和终端设备302-307。图3中仅示出了一个网络设备和六个终端设备。图3仅为示意图，并不构成对本申请实施例信号传输方法的适用场景的限定。
其中，终端设备，也可以称为用户设备(user equipment，UE)、终端、接入终端、用户单元、用户站、移动站、远方站、远程终端、移动设备、用户终端、无线通信设备、用户代理或用户装置等。终端设备可以是无线终端，也可以是有线终端。无线终端可以是指一种具有无线收发功能的设备，可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述终端设备可以是无人机、物联网(internet of things，IoT)设备(例如，传感器，电表，水表等)、车联网(vehicle-to-everything，V2X)设备、无线局域网(wireless local area networks，WLAN)中的站点(station，ST)、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备(也可以称为穿戴式智能设备)。终端设备还可以为下一代通信系统中的终端，例如，5G通信系统中的终端或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的终端等，本申请实施例对此不作限定。示例性的，在图3中，终端设备可以为高铁通信设备302、智能空调303、智能加油机304、 手机305、智能茶杯306、打印机307等，本申请实施例对此不作限定。
网络设备是无线通信网络中的设备，例如将终端设备接入到无线通信网络的无线接入网(radio access network，RAN)节点。目前，一些RAN节点的举例为：gNB、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station，BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)，或5G通信网络或5G之后的通信网络中的网络侧设备等。网络设备可以是一个物理实体，也可以是多个物理实体的组合，该多个物理实体可以部署在同一位置，也可以部署在不同位置，该多个物理实体用于共同实现该网络实体的功能。
本申请实施例描述的通信系统以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定。本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面，对本申请实施例提供的信号传输方法进行具体阐述。本申请实施例信号传输方法的技术构思如下：网络设备确定第一资源，其中，第一资源和第二资源在时域上不重叠，第二资源用于发送同步信号块SSB信号，第一资源与第二资源存在对应关系。然后，网络设备在第一资源上传输至少一个第一信号，其中，第一信号用于探测目标的属性。也就是说，网络设备确定的第一资源是时域上与第二资源不重叠的资源，两者之间在资源位置上存在对应关系。如此，第一信号与SSB信号的传输时间不同，以使第一信号与SSB信号不发生碰撞，互不干扰，从而提升系统通信效率。示例性的，第一信号可以是雷达探测信号，也可以是雷达探测信号的回波信号。第一资源与第二资源存在对应关系，具体说明可以参见下述介绍，此处不再赘述。
作为一种实施方式，第一资源是基于第二资源确定的。也就是说，在第二资源的资源位置保持不变的情况下，通过调整第一信号的资源位置，以得到第一资源，从而实现第一资源与第二资源在时域上不重叠。其中，第二资源是从SSB信号的候选位置中确定的用于发送SSB信号的资源。在本申请实施例中，SSB信号的候选位置是3GPP协议技术规范(technical specification，TS)38.213规定的候选位置，具体参见上述5种情况的介绍。
作为另一种实施方式，第二资源是基于第一资源确定的。也就是说，在第一信号的传输周期保持不变的情况下，通过调整SSB信号的候选位置，以得到第二资源，从而实现第一资源与第二资源在时域上不重叠。
下面结合具体示例，对本申请实施例进行说明。下述实施例中各个网元之间的消息名字或消息中各参数的名字等只是一个示例，具体实现中也可以是其他的名字。在本申请实施例中，以单个时隙为粒度时，在时域符号的前缀为普通循环前缀(normal cyclic prefix，NCP)的情况下，时域符号的索引值范围是[0，13]。以连续两个时隙为粒度时，时域符号的索引值范围是[0，27]。第一资源用于传输至少一个第一信号。第二资源用于传输至少一个SSB信号。第三资源是基于第一信号的传输周期确定的资源，即不考虑与SSB的干扰，第一信号所在的资源。第一资源与第二资源存在对应关系，可以是指，在预设数量的时域 资源单元中，第一资源与第二资源在资源位置上存在对应关系，如一个第一资源与多个第二资源中的每一第二资源在资源位置上存在对应关系，或多个第一资源中的每一第一资源与多个第二资源中的每一第二资源在资源位置上存在对应关系。例如，以单个时隙为粒度，在同一时隙中，第一资源的数量为一个，占用索引13的时域符号。第二资源的数量为两个，占用的时域符号索引包括：4、5、6、7、8、9、10、11。该时隙中的一个第一资源与两个第二资源在时域符号上分别存在对应关系，如第一资源与首个第二资源在时域上间隔9个时域符号，第一资源与第二个第二资源在时域上间隔5个时域符号。再如，以单个时隙为粒度，在同一时隙中，第一资源的数量为两个，占用的时域符号索引包括3和13。第二资源的数量为两个，占用的时域符号索引包括：4至11。在该时隙中，每个第一资源与每个第二资源在时域符号上分别存在对应关系，如首个第一资源与首个第二资源在时域上连续，首个第一资源与第二个第二资源在时域上间隔5个时域符号，第二个第一资源与首个第二资源在时域上间隔9个时域符号，第二个第一资源与第二个第二资源在时域上间隔4个时域符号。又如，以两个连续的时隙为粒度，在两个连续的时隙中，第一资源的数量为三个，占用的时域符号索引包括3、13和24。第二资源的数量为四个，占用的时域符号索引包括：4至11、16至23。在该时隙中，每个第一资源与每个第二资源在时域符号上分别存在对应关系，如首个第一资源与四个第二资源在时域上的位置关系依次为：时域连续、间隔5个时域符号、间隔13个时域符号、间隔20个时域符号，第二个第一资源与四个第二资源在时域上的位置关系依次为：间隔9个时域符号、间隔5个时域符号、间隔3个时域符号、间隔7个时域符号，第三个第一资源与四个第二资源在时域上的位置关系依次为：间隔20个时域符号、间隔16个时域符号、间隔8个时域符号、时域连续。在本申请实施例中，两个资源之间的间隔，是指，以两个资源的索引为基准来确定的差值。例如，同一时隙中，资源1占用时域符号的索引为1，资源2占用时域符号的索引为6，则资源1与资源2之间的间隔为5个时域符号。应理解，两个资源之间的间隔，也可以同等替换为，位于两个资源之间的时域资源单元数量，但在数值上相差1。仍以上述资源1和资源2为例，位于资源1与资源2之间的时域符号数量为4个。另外，上述至少一个第一信号也可以作为一个整体，描述为第一信号。第一资源为至少一个，且至少一个第一资源中每个第一资源上承载一个信号，每个第一资源上承载的信号，描述为子信号。也就是说，第一信号包括至少一个子信号。为了描述方便，本申请实施例中，是以网络设备为网络设备301，终端设备为终端设备305为例进行介绍。在此统一说明，以下不再赘述。
本申请实施例提供一种信号传输方法400，该信号传输方法400应用在雷达通信一体化的信号传输过程中。参见图4，该方法包括如下步骤：
S401、网络设备301确定第一资源。
其中，第一资源和第二资源在时域上不重叠。第一资源的数量为一个或多个，且多个第一资源中任意两个相邻的第一资源在时域上可以连续，也可以不连续。每个第一资源可以是一个时域符号。具体的，网络设备301可以确定一个或多个第一资源。可以理解的，第一资源和第二资源在时域上不重叠，当第一资源的数量和第二资源的数量都为多个时，该多个第一资源中任一第一资源和多个第二资源中任一第二资源在时域上均不重叠。
其中，每个第二资源可以是时域上连续的四个时域符号，详见图1的相关说明。第二 资源的数量可以为多个，在多个第二资源中，任意两个相邻的第二资源在时域上可以连续，如图2a中索引为0的SSB占用的时域资源和索引为1的SSB占用的时域资源是连续的，索引为2的SSB占用的时域资源和索引为3的SSB占用的时域资源是连续的。任意两个第二资源也可以不连续，如图2a中，索引为1的SSB占用的时域资源和索引为2的SSB占用的时域资源是不连续的，再如图2b中，索引为0的SSB占用的时域资源和索引为1的SSB占用的时域资源是不连续的。
其中，S401的具体实现方式包括如下两种：
作为第一种实现方式，第一资源是基于第二资源确定的。也就是说，在第二资源的资源位置保持不变的情况下，通过调整第一信号的资源位置，以得到第一资源，从而实现第一资源与第二资源在时域上不重叠。其中，第二资源是从SSB信号的候选位置中确定的用于发送SSB信号的资源。示例性的，当第三资源与SSB信号的候选位置重叠，则第一资源不包含第三资源中与SSB信号的候选位置重叠的资源。下面，分三种示例进行介绍：
作为第一种实现方式的示例一、在第二资源的资源位置密度较高的情况下，第一信号在目标时长内仍保持等间隔传输。其中，目标时长是由第二资源所在的至少一个时隙构成。以第二资源属于3GPP TS 38.213规定的资源位置为例，目标时长是一个半帧，为5ms。第二资源的资源位置密度较高，可以是指，SSB信号的数量小于或等于64，即可以理解为一个SSB突发(burst)中包括的SSB信号的数量小于或等于64。例如，在协议3GPP TS 38.213中，传输SSB信号的子载波的子载波间隔为120kHz的情况下，SSB信号的候选位置最大可支持64个，即公式(4)中，n的取值数量达到最大，为16个。在SSB信号的候选位置占满的情况下，SSB信号的数量为64，即5ms内发送64个SSB信号。
也就是说，在目标时长内，任意相邻两个的第一信号之间的间隔相同。换言之，在目标时长内，将上述至少一个第一信号中相邻两个第一信号之间的间隔记为第一间隔的情况下，第一间隔为多个，且多个第一间隔的时间长度相同。其中，第一间隔为多个，是指：网络设备301在目标时长内传输多个第一信号，每相邻两个第一信号之间存在一个第一间隔。如此，第一个间隔的数量为多个。
示例性的，在目标时长内，第一资源包括索引值为第一预设值的时域资源单元。以时域资源单元为时域符号为例，在传输SSB信号的子载波间隔为120kHz的情况下，以单个时隙为粒度，第二资源始终不占用的时域符号索引如下：0、1、12、和13。所以，第一预设值包括以下其中一项：0、1、12、或13。即第一资源在目标时长内占用时隙内的时域符号0、1、12、或13中的一个，与第二资源在时域上不重叠，从而避免第一信号与SSB信号发生碰撞。具体的，第一预设值可以是0，1，12，13，{0，1}，{12，13}中的一项，其中，{0，1}表示同时占用时域符号0和时域符号1。应理解，以SSB信号的子载波间隔为120kHz为例，在目标时长(5ms)内，网络设备301在每个时隙中的时域符号12上传输第一信号的情况下，存在40个第一间隔，且每个第一间隔都是1个时隙(即14个符号)。在目标时长(5ms)内，网络设备301在每个时隙中的时域符号0和时域符号1上传输第一信号的情况下，存在40个第一间隔，且每个第一间隔都是13个时域符号。
示例性的，参见图5a，图5a示出了一种资源分布示意图。第二资源的资源位置是基于3GPP TS 38.213的情况D确定的。在SSB信号的数量为64的情况下，即SSB信号占用了半帧内的所有的SSB的候选位置。在半帧内，第一资源的时域符号索引为13，即第一 资源为多个，且为前5ms中每个时隙上索引13的时域符号。也就是说，网络设备301在5ms内每个时隙中的时域符号13上传输第一信号。以两个连续的时隙为粒度，第二资源始终占用的时域符号索引如下：4、5、6、7、8、9、10、11、16、17、18、19、20、21、22、23。如此，多个第一资源中任一第一资源与多个第二资源中任一第二资源在时域上不重叠。并且，每相邻两个第一信号之间存在一个第一间隔的情况下，每个第一间隔的时间长度相同。
应理解，仍以时域资源单元为时域符号为例，在传输SSB信号的子载波间隔为120kHz的情况下，若以相邻两个时隙为粒度，则第二资源的资源位置始终不占用的时域符号索引如下：0、1、2、3、12、13、14、15、24、25、26、27。所以，在每两个第一预设值中，一个第一预设值包括以下其中一项：0、1、2、3、12、13，另一个第一预设值包括以下其中一项：14、15、24、25、26、27。如此，多个第一资源中任一第一资源与多个第二资源中任一第二资源在时域上不重叠，从而避免第一信号与SSB信号发生碰撞。在以相邻两个时隙为粒度的情况下，第一信号在目标时长内可以保持等间隔传输，比如，两个第一预设值为0和14，1和15，12和26，13和27，{0和1，14和15}，{12和13，26和27}中的一组时，相邻两个第一信号间的第一间隔都是1个时隙。第一信号在目标时长内也可以不保持等间隔传输，比如，两个第一预设值为0和15，1和14，12和27，13和26，{0和1，24和25}，{12和13，25和26}中的一组时，相邻两个第一信号间的第一间隔是不一样的，即第一信号的传输是不等间隔的，但网络设备301在每个时隙中能够传输一个第一信号，且不与SSB信号发生碰撞。
作为第一种实现方式的示例二、在第二资源的资源位置密度较高的情况下，第一信号在目标时长内仍能够保持较高的时域密度。其中，目标时长的介绍可以参见上述示例一的相关说明，此处不再赘述。
此种情况下，在目标时长内，两个相邻的第一信号之间的间隔不全一样，即至少存在“两个相邻的第一信号之间的间隔”与“另外两个相邻的第一信号之间的间隔”不同。换言之，在目标时长内，第一间隔为多个，且多个第一间隔中至少两个第一间隔的时间长度不同。其中，“第一间隔为多个”可以参见上述示例一的相关说明，此处不再赘述。例如，以两个时隙为粒度，在目标时长(5ms)内，网络设备301在时域符号3、13和24上分别传输第一信号的情况下，存在3种长度的第一间隔，即时域符号3与时域符号13之间的第一间隔为10个时域符号，时域符号13与时域符号24之间的第一间隔为11个时域符号，时域符号24与下一个时隙中的时域符号3之间的第一间隔为7个时域符号。
示例性的，在目标时长内，第一资源包括索引值为第二预设值的时域资源单元。以时域资源单元为时域符号为例，在传输SSB信号的子载波间隔为120kHz的情况下，以连续两个时隙为粒度，第二资源的资源位置始终不占用的时域符号索引如下：0、1、2、3、12、13、14、15、24、25、26和27。基于此，第二预设值的取值包括如下两种可能的设计：
在第一种可能的设计中，第二预设值包括以下至少三项：0、1、2、3、12、13、14、15、24、25、26、或27。其中，第二预设值中任意两项之间的差值大于或等于第三预设值。示例性的，第三预设值的取值可以是6，此种情况下，第二预设值的取值可以参见第二种可能的设计，以使每个时隙中存在至少一个第一资源，即网络设备301在每个时隙中至少传输一个第一信号。并且，第二预设值中任意两项之间的差值大于或等于第三预设值，也 使得第一资源在时域上是非连续的，且在一定程度上保证了第一资源在时域上的分布是均匀的。第二预设值的取值至少是三项，即每两个时隙中，至少存在三个第一资源，从而使得网络设备301在每两个时隙中至少传输三个第一信号。而在示例一的半帧内，每个时隙上存在一个第一资源，即每个时隙传输一个第一信号。相比于示例一而言，示例二提升了第一信号的时域密度，有利于提高雷达探测精度。当然，第三预设值的取值也可以是其他数值，如第三预设值的取值可以是1，第二预设值可以是{0，2，14}，{0，2，15}，{0，3，24}，{0，3，27}，{12，15，25}，{12，15，27}，{12，24，27}，{15，24，27}中的一项。也就是说，网络设备301可以在两个SSB信号之间的资源上传输两个第一信号，网络设备301也可以在两个SSB信号之间的资源上不传输第一信号。但网络设备301在两个时隙上总能够传输三个第一信号，以提升第一信号的时域密度。
在第二种可能的设计中，第二预设值的数量为三个。其中，三个第二预设值满足：
第一个第二预设值包括以下其中一项：0、1、2、或3。
第二个第二预设值包括以下其中一项：12、13、14、或15。
第三个第二预设值包括以下其中一项：24、25、26、或27。
换言之，在两个相邻的时隙上，网络设备301在两个SSB信号之间的资源上传输一个第一信号，且网络设备301在两个时隙上总能够传输三个第一信号。示例性的，第二预设值可以是以下其中一项：{0，12，24}，{1，13，25}，{2，14，26}，{3，15，27}，{0，13，24}，{1，13，24}，{2，14，24}，{3，13，27}，{0，15，24}，{1，15，24}，{2，15，24}，或{3，15，27}。以第二预设值包括{0，12，24}为例，网络设备301在时域符号0、12和24上分别传输第一信号。
也就是说，第二预设值之间的差值是相对均匀的。相应的，以第二预设值为索引的时域符号在时隙上的分布是相对均匀的，也就使得第一信号在时域上尽可能均匀地传输，既保证了第一信号的时域密度，又避免了与SSB信号发生碰撞。
或者，第一种实现方式的示例二所提供的方式，也可以理解为：当第三资源中部分资源与SSB信号的候选位置重叠，则第一资源包括至少包括：将第三资源中与SSB信号的候选位置重叠的资源提前或延后至少一个时域符号之后的资源，以避免网络设备301同时传输第一信号和SSB信号，同时还能够尽可能地保证第一资源均匀分布，以保证雷达探测精度。例如，以图5b为例，按照第一信号的传输周期来说，第三资源包括时域符号6。但时域符号6用于承载SSB信号，所以，将“时域符号6”这一第三资源前移，如图5b中的时域符号3所示，时域符号3用于传输第一信号。再如，仍以图5b为例，按照第一信号的传输周期来说，第三资源包括时域符号20。但时域符号20仍承载了SSB信号，所以，将“时域符号20”这一第三资源后移，如图5b中的时域符号24所示，时域符号24用于传输第一信号。应理解，在图5b所示的场景中，第三资源包括时域符号27。但执行前移和后移之后，时域符号3和时域符号24均用于传输第一信号，时域符号27可以不再用于传输第一信号，以避免第一信号频繁传输，节省传输资源，且贴近第一信号原有的传输周期。当然，时域符号27也可以用于传输第一信号，以降低网络设备的运算量，本申请实施例对此不作限定。
示例性的，参见图5b，图5b示出了一种资源分布示意图。第二资源的资源位置是基于3GPP TS 38.213的情况D确定的。在SSB信号的数量为64的情况下，在半帧内，第一 资源的时域符号索引包括3、13、24，既未与SSB信号发生碰撞，又能够保证第一信号尽可能均匀地传输。
作为第一种实现方式的示例三、在第二资源的资源位置密度较低的情况下，SSB信号只占用了部分候选位置。在传输SSB信号的子载波间隔为120kHz的情况下，SSB信号的时域符号索引满足：
{4，16}+28*n    公式(6)
其中，n＝0，1，2，3，5，6，7，8，10，11，12，13，15，16，17，18。
其中，第二资源的资源位置密度较低，可以是指，SSB信号的数量小于或等于32，即可以理解为一个SSB突发中包括的SSB信号的数量小于或等于32，即SSB信号的候选位置最大可支持32个，即公式(6)中，n的取值数量最大，为16个。在SSB信号的候选位置占满的情况下，SSB信号的数量为32，即5ms内发送32个SSB信号。
此种情况下，在目标时长内，两个相邻的第一信号之间的间隔不全一样，具体可以参见上述示例二的描述，此处不再赘述。示例性的，在目标时长内，第一资源包括索引值为第二预设值的时域资源单元。以时域资源单元为时域符号为例，以连续的两个时隙为粒度，第二预设值满足如下公式：
K＝7*k-1    公式(7)
其中，K表示第二预设值，K＝2、3、4。即第二预设值的取值包括13、20、27。结合公式(6)和公式(7)可知，以两个相邻的时隙为粒度，第二资源的时域符号索引为：4、5、6、7、16、17、18、19。第一资源的时域符号索引为：13、20、27。即按照第一信号的传输周期来说，时域符号6用于传输第一信号。但是，时域符号6用于发送SSB信号，所以，时域符号6不再用于传输第一信号。也就是说，在目标时长内，与第二资源冲突的第三资源不再用于传输第一信号。换言之，在目标时长内，第一资源由第三资源中与SSB信号的候选位置不重叠的资源构成。
示例性的，参见图5c，图5c示出了一种资源分布示意图。第二资源的资源位置是基于上述公式(6)确定的。在SSB信号的数量为小于或等于32的情况下，在半帧内，以连续的两个时隙为粒度，第一资源的时域符号索引包括13、20、27。
也就是说，以第一信号的传输周期为7个时域符号为例，在第一信号的传输位置与SSB信号的传输位置(即第二资源)重叠的情况下，第一信号被丢弃，网络设备301不传输第一信号，即第二预设值的取值不包括6，从而避免第一信号与SSB信号发生碰撞，又能够保证第一信号的时域密度。
需要说明的是，在第一种实现方式的目标时长外，SSB信号不再发送。换言之，目标时长外，不存在第二资源。第一信号可以保持原有的传输周期。也就是说，目标时长内相邻两个第一信号之间的时间间隔与目标时长外相邻两个第一信号之间的时间间隔不同。在目标时长外，将上述至少一个第一信号中相邻两个第一信号之间的间隔记为第二间隔的情况下，第二间隔为多个，且多个第二间隔的时间长度相同，但与第一间隔的时间长度不同，当第一间隔为多个的情况下，第二间隔与至少一个第一间隔不同。其中，第二间隔为多个，是指：网络设备301在目标时长外传输多个第一信号，每相邻两个第一信号之间存在一个第二间隔。如此，第二个间隔的数量为多个。在目标时长外，第一资源包括索引值为预设值1的时域资源单元。在时域资源单元为时域符号的情况下，预设值1的取值可以包括： 6、13，具体参见图5a、图5b和图5c所示。
应理解，在本申请实施例中，仅以第一信号的传输周期为7个符号为例，进行介绍，在第一信号的传输周期是其他时长的情况下，目标时长外，第一资源的资源位置也可以按照其他的间隔进行设计，以满足不同场景下对第一信号的传输需求，本申请实施例对此不作限定。
作为第二种实现方式，第二资源是基于第一资源确定的。也就是说，在第一信号的传输周期保持不变的情况下，通过调整SSB信号的候选位置，以得到第二资源，从而实现第一资源与第二资源在时域上不重叠。下面，分两个示例进行介绍：
作为第二种实现方式的示例一、在第二资源的资源位置密度较低的情况下，SSB信号只占用了部分候选位置。在传输SSB信号的子载波间隔为120kHz的情况下，通过两种可能的设计，对第二资源进行介绍：
在第一种可能的设计中，在目标时长内，第二资源包括索引值为第四预设值的时域资源单元，第四预设值满足如下公式：
Figure PCTCN2022087421-appb-000009
其中，M表示第四预设值，N为整数，且0≤N≤27，k为正整数。
由公式(8)可知，在第一信号的传输周期为7个时域符号的情况下，第一资源的时域符号索引满足：7*k-1。在N遍历28个整数(即从0至27)的过程中，承载SSB信号的时域符号索引不等于第一资源的时域符号索引，从而避免第一资源与第二资源在时域上重叠。
示例性的，以两个相邻时隙为粒度，第一资源的时域符号索引包括：6、13、20、27。例如，在N＝0的情况下，第二资源的时域符号索引包括：0、1、2、3，均不等于第一资源的时域符号索引，所以，时域符号{0、1、2、3}可以作为第二资源，用于发送SSB信号。再如，在N＝3的情况下，第二资源的时域符号索引包括：3、4、5、6。此种情况下，第二资源的时域符号索引中有一个数值“6”等于第一资源的时域符号索引，所以，时域符号{3、4、5、6}不可以作为第二资源，不用于发送SSB信号。
应理解，在第一种可能的设计中，仅以第一信号的传输周期为7个时域符号为例，进行介绍，在第一信号的传输周期是其他时长的情况下，如第一信号的传输周期为T个时域符号，上述公式(8)可以替换为：
Figure PCTCN2022087421-appb-000010
其中，M表示第四预设值，T为第一信号的传输周期，N为整数，且0≤N≤27，k为正整数。也就是说，在第一信号的传输周期为T个时域符号的情况下，第一资源的时 域符号索引满足：T*k-1。在N遍历28个整数(即从0至27)的过程中，承载SSB信号的时域符号索引不等于第一资源的时域符号索引，即第二资源的时域符号索引(即第二资源的时域符号索引M、M+1、M+2、M+3)取值不等于第一资源的时域符号索引取值，从而避免第一资源与第二资源在时域上重叠。
示例性的，以两个相邻时隙为粒度，以T＝8为例，第一资源的时域符号索引包括：7、15、23。例如，在N＝0的情况下，第二资源的时域符号索引包括：0、1、2、3，均不等于第一资源的时域符号索引，所以，时域符号{0、1、2、3}可以作为第二资源，用于发送SSB信号。再如，在N＝4的情况下，第二资源的时域符号索引包括：4、5、6、7。此种情况下，第二资源的时域符号索引中有一个数值“7”等于第一资源的时域符号索引，所以，时域符号{4、5、6、7}不可以作为第二资源，不用于发送SSB信号。
在第二种可能的设计中，在目标时长内，第二资源包括索引值为第四预设值的时域资源单元，第四预设值满足如下公式：
Figure PCTCN2022087421-appb-000011
其中，M表示第四预设值，N包括以下取值中的至少两项：0、1、2、7、8、9、14、15、16、21、22、或23。由图1的介绍可知，一个SSB信号占四个时域符号，因此，第四预设值中任意两项之间的差值大于4，以避免SSB信号之间占用的资源重叠。示例性的，第四预设值可以是以下其中一个：{0，7}，{0，8}，{0，9}，{0，22}，{1，7}，{1，8}，{1，9}，{1，22}，{1，23}，{1，8，16}，或{2，9，16}。应理解，在第四预设值中任意两项之间的差值大于4的情况下，第四预设值的取值只要取自上述取值(即0、1、2、7、8、9、14、15、16、21、22、或23)即可。
示例性的，参见图5d，图5d示出了一种资源分布示意图。以两个时隙为粒度，在N包括8和16的情况下，第二资源的资源位置(即承载SSB信号的位置)包括时域符号8、9、10、11、16、17、18、19，如图5d所示，均与第一资源中任一资源不重叠。如此，网络设备301传输的第一信号与SSB信号不发生碰撞。
作为第二种实现方式的示例二、在第二资源的资源位置密度较高的情况下，SSB信号占用了半帧内所有的候选位置。在传输SSB信号的子载波间隔为120kHz的情况下，对SSB信号的时域符号索引满足：
{2，8，16，22}+28*n     公式(11)
其中，n＝0，1，2，3，5，6，7，8，10，11，12，13，15，16，17，18。
示例性的，在图5e中，在n＝0的情况下，索引0标识的SSB信号为半帧中的首个SSB信号，所占时域符号的索引为2至5。索引1标识的SSB信号为半帧中的第二个SSB信号，所占时域符号的索引为8至11。索引2标识的SSB信号为半帧中的第三个SSB信号，所占时域符号的索引为16至19。索引3标识的SSB信号为半帧中的第四个SSB信号，所占时域符号的索引为22至25。
也就是说，以两个相邻时隙为粒度，在第一信号的传输周期是7个时域符号的情况下，第一资源的时域符号索引包括：6、13、20、27。例如，结合公式(4)，在首个时域符号索引为4的情况下，第二资源的时域符号索引包括：4、5、6、7，即第二资源的时域符号索引中数值“6”等于第一资源的时域符号索引，即与第一资源重叠，所以，将“4”调整为 “2”，如公式(11)所示，如此，首个时域符号索引2的第二资源包括：时域符号2、时域符号3、时域符号4和时域符号5，未与第一资源重叠。再如，结合公式(4)，在首个时域符号索引为20的情况下，第二资源的时域符号索引包括：20、21、22、23，即第二资源的时域符号索引中数值“20”等于第一资源的时域符号索引，即与第一资源重叠，所以，将“20”调整为“22”，如公式(11)所示，如此，首个时域符号索引22的第二资源包括：时域符号22、时域符号23、时域符号24和时域符号25，未与第一资源重叠。
需要说明的是，在第二种实现方式中，无论在目标时长内，还是在目标时长外，第一信号保持原有的传输周期，即第一间隔与第二间隔的时间长度相同。当第一间隔和第二间隔的数量为多个的情况下，多个第二间隔中每一第二间隔与多个第一间隔中每一第一间隔均相同。其中，目标时长是由SSB信号的候选位置所在的至少一个时隙构成。第一间隔与第二间隔可以参见第一种实现方式的介绍，此处不再赘述。在第二种实现方式中，第一资源包括索引值为预设值1的时域资源单元。在时域资源单元为时域符号的情况下，预设值1的取值可以包括：6、13，如图5d所示。
S402、网络设备301在第一资源上传输至少一个第一信号。
其中，网络设备301具有感知功能，第一信号用于探测目标的属性。目标的属性包括以下至少一项：移动速度、位置、或形状大小。示例性的，若终端设备305处于第一信号的探测区域内，且雷达截面积(radar cross-section，RCS)大于阈值，则第一信号探测到的目标包括终端设备305，网络设备301能够接收到由终端设备305反射的回波信号，从而感知终端设备305的位置等属性。反之，若终端设备305处于第一信号的探测区域外，或RCS小于或等于阈值，则网络设备301无法接收到由终端设备305反射的回波信号，即网络设备301的感知对象不包括终端设备305，也就无法探测终端设备305的位置等属性。当然，除上述终端设备305之外，目标也可以是其他物体，反射回波信号，网络设备301接收到回波信号之后，也就能够感知到目标的属性。
其中，S402中的第一资源是S401中的第一资源。S402中的第一资源可以是基于第二资源确定的，参见S401中第一种实现方式的介绍，S402中的第一资源也可以用于确定第二资源，参见S402中第二种实现方式的介绍，此处不再赘述。每个第一资源承载一个第一信号。在第一资源为一个的情况下，网络设备301在第一资源上传输一个第一信号。在第一资源为多个的情况下，网络设备301在多个第一资源的每一第一资源上传输一个第一信号。
示例性的，S402的具体实现过程包括：
示例1，网络设备301在第一资源上发送至少一个第一信号，如在第一资源为一个的情况下，网络设备301在第一资源上发送一个第一信号。在第一资源为多个的情况下，网络设备301在多个第一资源的每一第一资源上发送一个第一信号。此种情况下，第一信号可以实现为雷达探测信号。
示例2，网络设备301在第一资源上接收至少一个第一信号，如在第一资源为一个的情况下，网络设备301在第一资源上接收一个第一信号。在第一资源为多个的情况下，网络设备301在多个第一资源的每一第一资源上接收一个第一信号。此种情况下，第一信号可以实现为雷达探测信号的回波信号。
示例3，网络设备301在第一资源上发送和接收第一信号，如在第一资源为一个的情 况下，网络设备301在第一资源上发送和接收第一信号。在第一资源为多个的情况下，网络设备301在多个第一资源的每一第一资源上发送和接收第一信号。此种情况下，发送的第一信号可以实现为雷达探测信号，接收的第一信号可以实现为雷达探测信号的回波信号。
示例4，在第一资源为多个的情况下，将多个第一资源划分为两部分，网络设备在一部分第一资源上执行上述三种示例(示例1～示例3)中的一种，网络设备在另一部分第一资源上执行上述三种示例(示例1～示例3)中的另一种。或者，将多个第一资源划分为三部分，网络设备在每一部分第一资源上执行上述三种示例(示例1～示例3)中的一种。
示例性的，分两种情况对S402进行介绍：
作为第一种情况，第一信号承载了通信信息。参见图6a，在执行S402之前，网络设备301执行S403：
S403、网络设备301向终端设备305发送第一指示信息。相应的，终端设备305接收来自网络设备301的第一指示信息。
其中，第一指示信息指示第一资源的索引值。
示例性的，第一指示信息可以携带第一资源的索引值。例如，在以单个时隙为粒度的情况下，第一指示信息可以是采用4个比特来指示第一资源的索引值。再如，在以两个时隙为粒度的情况下，第一指示信息可以是采用5个比特来指示第一资源的索引值。第一资源的索引值可以参见S401的相关介绍，此处不再赘述。
或者，第一指示信息也可以指示第一资源与第二资源之间的偏移量。其中，偏移量的单位为时域符号，偏移量的取值指示第一资源与第二资源之间间隔的时域符号的数量。偏移量可以通过预设数量的比特来表示。例如，偏移量较小，如小于8个时域符号的情况下，第一指示信息可以是采用3个比特来指示偏移量。再如，偏移量较大，如大于8个时域符号的情况下，第一指示信息可以是采用4个或5个比特来指示偏移量。
示例性的，第一指示信息可以是高层信令，比如无线资源控制(radio resource control，RRC)信令，或者，第一指示信息也可以是物理层信令，如下行链路控制信息(downlink control information，DCI)。
在S403被执行的情况下，S402具体实现为S402a：
S402a、网络设备301在第一资源上向终端设备305发送通信信息。相应的，终端设备305在第一资源上接收来自网络设备301的通信信息。
其中，通信信息承载于第一信号。通信信息包括但不限于：物理下行共享信道(physical downlink shared channel，PDSCH)等。终端设备305通过解调、解码等处理，从第一信号中获取通信信息。
作为第二种情况，第一信号上未承载通信信息。此种情况下，网络设备301在执行S402之前，无需执行S403。即网络设备301按照第一资源的资源位置传输第一信号即可。
对于网络设备301而言，网络设备301还能够发送SSB信号，如图6b所示的步骤：
S404、网络设备301在第二资源上向终端设备305发送至少一个SSB信号。相应的，终端设备305可以在第二资源上接收来自网络设备301的至少一个SSB信号。
其中，S404中的第二资源是S401中的第二资源。S404中的第二资源可以用于确定第一资源，参见S401中第一种实现方式的介绍，S404中的第二资源也可以是基于第一资源确定的，参见S402中第二种实现方式的介绍，此处不再赘述。每个第二资源承载一个SSB 信号。在第二资源为一个的情况下，网络设备301在第二资源上发送一个SSB信号。在第二资源为多个的情况下，网络设备301在多个第二资源的每一第二资源上发送一个SSB信号。
示例性的，分两种情况对S404进行介绍：
作为第一种情况，第二资源是基于第一资源确定的，详见S401中第二种实现方式的介绍。参见图6b，在执行S404之前，网络设备301执行S405：
S405、网络设备301向终端设备305发送第二指示信息。相应的，终端设备305接收来自网络设备301的第二指示信息。
其中，第二指示信息指示第二资源的索引值。
示例性的，第二指示信息可以携带第二资源的索引值。例如，在以单个时隙为粒度的情况下，第二指示信息可以是采用4个比特来指示第二资源的索引值。再如，在以两个时隙为粒度的情况下，第二指示信息可以是采用5个比特来指示第二资源的索引值。第二资源的索引值可以参见S401的相关介绍，此处不再赘述。
或者，第二指示信息也可以指示第二资源与SSB信号的候选位置之间的偏移量。其中，偏移量的单位为时域符号，偏移量的取值指示第二资源与SSB信号的候选位置之间间隔的时域符号的数量。偏移量可以通过预设数量的比特来表示。例如，偏移量较小，如小于8个时域符号的情况下，第二指示信息可以是采用3个比特来指示偏移量。再如，偏移量较大，如大于8个时域符号的情况下，第二指示信息可以是采用4个或5个比特来指示偏移量。
示例性的，第二指示信息可以是高层信令，比如信令，或者，第二指示信息也可以是物理层信令，如DCI。
也就是说，在第一资源的资源位置保持不变，且第二资源是基于第一资源确定的情况下，网络设备301先为终端设备305指示第二资源的索引值，以使终端设备305在第二指示信息指示的资源位置上接收SSB信号。
需要说明的是，终端设备305在执行S405之前的预设时长内(如n秒)，网络设备301在已知的资源上向终端设备305发送SSB信号。相应的，终端设备305在可以已知的资源上接收来自网络设备301的SSB信号。其中，已知的资源是基于已有协议(如3GPP TS38.213)规定的资源。如此，通过上述预设时长内的SSB信号，终端设备305与网络设备301实现同步，然后，终端设备305执行S405。另外，网络设备301也可以不执行S405，此种情况下，终端设备305执行盲检测，即扫描每一时域符号。若某些时域符号上传输了SSB信号，则终端设备305即可检测到来自网络设备301的SSB信号。
作为第二种情况，第二资源用于确定第一资源，详见S401中第一种实现方式的介绍。此种情况下，网络设备301在执行S404之前，无需执行S405。
需要的说明的是，在网络设备301向终端设备305发送指示信息(如上述第一指示信息、第二指示信息)之后，若终端设备305接收到指示信息，终端设备305可以向网络设备301发送应答(acknowledgement，ACK)。反之，若终端设备305未接收到指示信息，则终端设备305向网络设备301发送否定应答(negative acknowledgement，NACK)。另外，在传输SSB信号的半帧中，第一资源的分布状况是一致的。即使在传输SSB信号的半帧中，一部分时隙中包括SSB信号的候选位置，另一部分时隙中不包括SSB信号的候选位 置，第一资源在两种时隙中的分布状态仍是一致的，以网络设备301始终以固定的图样(pattern)来传输第一信号，避免第一信号的资源位置频繁变化，也简化网络设备301确定第一资源的复杂度。
可以理解的，图6a和图6b所示的方法可以单独实施，也可以组合实施。本申请对此不作限制。
以上均是以第一资源和第二资源在时域上不重叠为例进行介绍的，以避免信号之间相互干扰。当然，第一资源和第二资源在时域上重叠的情况下，第一资源和第二资源在频域上不重叠也能够避免信号之间相互干扰。本申请实施例还提供另一种信号传输方法。该信号传输方法的技术构思如下：网络设备确定第一资源。其中，第一资源和第二资源在时域上重叠，且在频域上不重叠，第二资源用于发送通信信号。第一资源与第二资源存在对应关系。然后，网络设备在第一资源上传输至少一个第一信号。这样一来，第一信号与通信信号采用频分复用的方式传输，以使第一信号与通信信号不发生碰撞，互不干扰，从而提升系统通信效率。
其中，第一资源与第二资源存在对应关系，可以是指，在预设数量的频域资源单元中，第一资源与第二资源在资源位置上存在对应关系，如，第一资源和第二资源的数量相同，且一一对应。或者，第一资源的数量与第二资源的数量不同，且多个第一资源中的一个第一资源与多个第二资源中的一个第二资源对应。例如，以频域资源单元为RB为例，在同一系统带宽中，第一资源的数量为多个，且每个第一资源占用索引为x 1的RB。第二资源的数量为多个，且每个第二资源占用索引为a 1的RB。其中，x 1<a 1。x 1为系统带宽中频率最小的X个RB的索引，X为正整数。以通信信号为SSB信号为例，由图1可知，一个SSB信号占用20个RB。x 1<a 1，可以理解为，第一资源对应的RB索引小于第二资源对应的20个RB中每个RB的索引。再如，仍以频域资源单元为RB为例，在同一系统带宽中，第一资源的数量为多个，且每个第一资源占用索引为y 1的RB。第二资源的数量为多个，且每个第二资源占用索引为a 1的RB。其中，a 1<y 1。y 1为系统带宽中频率最大的Y个RB的索引，Y为正整数。以通信信号为SSB信号为例，由图1可知，一个SSB信号占用20个RB。a 1<y 1，可以理解为，第一资源对应的RB索引大于第二资源对应的20个RB中每个RB的索引。第一信号的描述可以参见信号传输方法400中的介绍，此处不再赘述。
如图7所示，本申请实施例提供一种信号传输方法700，该信号传输方法700应用在雷达通信一体化的信号传输过程中。参见图7，该方法包括如下步骤：
S701、网络设备301确定第一资源。
其中，第一资源和第二资源在时域上重叠，在频域上不重叠。第一资源的数量为一个或多个，且多个第一资源中任意两个相邻的第一资源在频域上可以连续，也可以不连续，如图8a所示。每个第一资源在频域上可以占一个或多个频域资源单元。具体的，网络设备301可以确定一个或多个第一资源。可以理解的，第一资源和第二资源在时域上重叠，在频域上不重叠，当第一资源的数量和第二资源的数量都为多个时，该多个第一资源中的一个第一资源和多个第二资源中的一个第二资源在时域上重叠，且在频域上不重叠。其中，第一资源的数量和第二资源的数量可以相同，且多个第一资源中的第一资源和多个第二资 源中的第二资源一一对应，即多个第一资源中的一个第一资源和多个第二资源中的一个第二资源在时域上重叠，且在频域上不重叠。或者，第一资源的数量和第二资源的数量可以不同，如多个第一资源中的至少两个第一资源和多个第二资源中的一个第二资源对应，如多个第一资源中的两个第一资源和多个第二资源中的一个第二资源在时域上重叠，且上述两个第一资源和上述一个第二资源在频域上均不重叠。
其中，每个第二资源可以是频域上连续的20个RB，详见图1的相关说明。第二资源的数量可以为多个，在多个第二资源中，任意两个相邻的第二资源在频域上可以占用相同索引的RB，也可以占用索引不同的RB，本申请实施例对此不作限定。在本申请实施例中，以任意两个相邻的第二资源在频域上可以占用相同索引的RB为例进行介绍。
示例性的，第一资源包括第一索引值指示的频域资源单元，第二资源包括第二索引值指示的频域资源单元。在频域资源单元实现为RB的情况下，以系统带宽包括90个RB，且索引值为0～89。示例性的，第一索引值的取值包括以下其中一项：45、46、47、{48、49}、或{50、51、52}等。其中，{48、49}表示第一资源包括索引为48的RB和索引为49的RB。以通信信号实现为SSB信号为例，第二索引值的取值包括以下其中一项：{0至19}、{1至20}、{2至21}、或{3至22}等。其中，{0至19}表示第二资源包括索引为0至19的RB。应理解，只要第一索引值中的任一数值与第二索引值中的全部数值不同即可，第一索引值和第二索引值还可以有其他取值，本申请实施例对此不作限定。下面，通过两种实现方式对第一索引值和第二索引值进行介绍：
作为第一种实现方式，第一索引值小于第二索引值。也就是说，第一索引值中的每一数值均小于第二索引值中的全部数值。
示例性的，参见图8a，以系统带宽为60个RB为例，一个频域资源单元可以包括一个RB。第一资源占用20个RB，第一索引值的取值为0至19，第一索引值可以记为{0至19}。也就是说，第一索引值指示系统带宽中频率最小的20个RB。在通信信号实现为SSB信号的情况下，第二资源占用的RB数量为20个，如第二索引值的取值包括30至49，第二索引值可以记为{30至49}。
或者，一个频域资源单元可以包括20个RB，也就是说，每20个RB记为一个频域资源单元。此种情况下，以系统带宽包括10个频域资源单元(即系统带宽包括200个RB)为例，频域资源单元的索引为0～9。第一资源占用一个频域资源单元(即第一资源占用20个RB)，且第一资源占用的频域资源单元位于系统带宽的前N个频域资源单元中的一个或多个频域资源单元，N为正整数。如第一索引值的取值为0，N的取值可以为3。也就是说，第一资源包括系统带宽的前3个频域资源单元中的一个频域资源单元。其中，系统带宽的前N个频域资源单元，可以理解为，系统带宽中全部频域资源单元按照频率从低到高的顺序排列，此种情况下，系统带宽的前N个频域资源单元，可以是指系统带宽中频率最小的N个频域资源单元。换言之，第一资源占用系统带宽中频率最小的X个频域资源单元，X为正整数，且X≤N。在通信信号实现为SSB信号的情况下，第二资源占用一个频域资源单元(即第二资源占用RB数量为20个)，如第二索引值的取值可以包括7。应理解，一个频域资源单元也可以包括其他数量的RB，如10个RB，本申请实施例对频域资源单元中RB的数量不作限定。
作为第二种实现方式，第一索引值大于第二索引值。也就是说，第一索引值中的 每一数值均大于第二索引值中的全部数值。
示例性的，参见图8b，仍以系统带宽为60个RB为例，一个频域资源单元可以包括一个RB。第一资源占用20个RB，第一索引值的取值包括40至59，第一索引值可以记为{40至59}。也就是说，第一索引值指示系统带宽中频率最大的20个RB。在通信信号实现为SSB信号的情况下，第二资源占用的RB数量为20个，第二索引值的取值包括0至19，第二索引值可以记为{0至19}。
或者，一个频域资源单元可以包括20个RB。此种情况下，以系统带宽包括10个频域资源单元(即系统带宽包括200个RB)为例，频域资源单元的索引为0～9。第一资源占用一个频域资源单元，且第一资源占用的频域资源单元位于系统带宽的末尾N个频域资源单元中的一个或多个频域资源单元，N为正整数。如第一索引值的取值为9，N的取值可以为3。也就是说，第一资源包括系统带宽的末尾3个频域资源单元中的一个频域资源单元。其中，系统带宽的末尾N个频域资源单元，可以理解为，系统带宽中全部频域资源单元按照频率从低到高的顺序排列，此种情况下，系统带宽的末尾N个频域资源单元，可以是指系统带宽中频率最大的N个频域资源单元。换言之，第一资源占用系统带宽中频率最大的Y个频域资源单元，Y为正整数，且Y≤N。在通信信号实现为SSB信号的情况下，第二资源占用一个频域资源单元，第二索引值的取值包括9，第二索引值可以记为9。
应理解，在采用频分复用的方式发送第一信号和通信信号的情况下，第一信号占用的频域资源单元的数量可以是一个，也可以是多个，本申请实施例对此不作限定。图8a和图8b仅以第一资源占用20个RB为例进行介绍，第一资源占用的频域资源单元数量可以有其他取值，本申请实施例对此不作限定。第一信号在时域上可以保持等间隔传输，也可以保持非等间隔传输，本申请实施例对此不作限定。在通信信号实现为SSB信号的情况下，SSB信号在时域上的分布情况可以参见名词解释部分示出的5种情况(如情况A、情况B、情况C、情况D、情况E)的介绍，此处不再赘述。
可选地，第一信号的带宽介绍如下：作为一种情况，第一信号的带宽与通信信号的带宽之和小于或等于系统带宽。例如，系统带宽为60个RB。通信信号的带宽为20个RB。此种情况下，第一信号的带宽可以是40个RB，也可以是35个RB。当然，第一信号的带宽还可以有其他取值，如20个RB，本申请实施例对此不作限定。也就是说，第一信号的带宽是基于系统带宽和通信信号的带宽确定的。如此，第一信号和通信信号分别占用系统带宽中不同的频域资源单元，所以，即使网络设备同时传输第一信号和通信信号，由于两者采用频分复用的方式传输，信号之间不会产生干扰。作为另一种情况，第一信号的带宽等于系统带宽。例如，系统带宽为60个RB。此种情况下，第一信号的带宽可以是60个RB。当然，系统带宽也可以有其他取值，如100个RB。相应的，第一信号的带宽为100个RB，本申请实施例对系统带宽的大小不作限定。
S702、网络设备301在第一资源上传输至少一个第一信号。
其中，S702的实现过程可以参见S402的介绍，此处不再赘述。
在本申请实施例信号传输方法700中，网络设备确定的第一资源是时域上与第二资源重叠，但频域上与第二资源不重叠的资源，两者之间在资源位置上存在对应关系。如此， 第一信号与通信信号通过不同的频域资源发送，以使第一信号与通信信号不发生碰撞，互不干扰，从而提升系统通信效率。
在一些实施例中，第一信号上可以承载通信信息，也可以不承载通信信息。下面，通过两种情况进行介绍：
作为第一种情况，第一信号承载通信信息。参见图9a，在执行S702之前，网络设备301执行S703：
S703、网络设备301向终端设备305发送指示信息1。相应的，终端设备305接收来自网络设备301的指示信息1。
其中，指示信息1指示第一资源的资源位置，如第一资源在频域上的资源位置。
示例性的，指示信息1可以携带第一资源的索引值，即第一索引值。例如，指示信息1可以是采用预设数量的比特来指示第一索引值。其中，第一索引值可以参见S701的相关介绍，此处不再赘述。
或者，指示信息1也可以指示第一资源与第二资源之间的偏移量。其中，偏移量的单位为频域资源单元，如RB，偏移量的取值指示第一资源与第二资源之间间隔的频域资源单元的数量。偏移量可以通过预设数量的比特来表示。例如，偏移量较小，如小于8个RB的情况下，指示信息1可以是采用3个比特来指示偏移量。再如，偏移量较大，如大于8个RB的情况下，指示信息1可以是采用4个或5个比特来指示偏移量。
可选的，指示信息1还指示第四资源的资源位置，如第四资源在频域上的资源位置。其中，第四资源与第二资源在时域上不重叠，第四资源也用于传输第一信号。
示例性的，指示信息1可以携带第四资源的索引值。在系统带宽为60个RB的情况下，一个频域资源单元包括一个RB。例如，第四资源占用的频域资源单元对应的索引值可以包括0至59。也就是说，第一信号在未与通信信号碰撞的情况下，第一信号的带宽等于系统带宽。示例性的，指示信息1还指示第四资源的索引值包括0至59。再如，第四资源占用的频域资源单元对应的索引值可以包括0至35。也就是说，第一信号在未与通信信号碰撞的情况下，第一信号占用系统带宽的一部分。示例性的，指示信息1还指示第四资源的索引值包括0至35。在系统带宽为100个RB的情况下，一个频域资源单元包括20个RB。例如，第四资源占用的频域资源单元对应的索引值可以包括0至4。也就是说，第一信号在未与通信信号碰撞的情况下，第一信号的带宽等于系统带宽。示例性的，指示信息1还指示第四资源的索引值包括0至4。再如，第四资源占用的频域资源单元对应的索引值可以包括0至3。也就是说，第一信号在未与通信信号碰撞的情况下，第一信号占用系统带宽的一部分。示例性的，指示信息1还指示第四资源的索引值包括0至3。
在第一信号承载通信信息的情况下，参见图9b，在执行S702之前，网络设备301还可以执行S704：
S704、网络设备301向终端设备305发送指示信息2。相应的，终端设备305接收来自网络设备301的指示信息2。
其中，指示信息2至少指示带宽。下面，通过两种示例进行介绍：
示例1，指示信息2指示以下两项：
第一项，第一带宽与通信信号的带宽之和小于或等于系统带宽。其中，第一带宽是第一信号与通信信号在时域上重叠时的带宽。示例性的，仍以系统带宽为60个RB。通信 信号的带宽为20个RB。此种情况下，第一带宽可以是40个RB，也可以是35个RB。当然，第一带宽还可以有其他取值，如20个RB，本申请实施例对此不作限定。也就是说，在第一信号的带宽为系统带宽的情况下，网络设备为终端设备指示第一信号与通信信号重叠时的第一带宽。相应的，终端设备基于指示信息2指示的第一带宽来接收第一信号。
第二项，第二带宽等于系统带宽。其中，第二带宽是第一信号与通信信号在时域上不重叠时的带宽。示例性的，仍以系统带宽为60个RB。此种情况下，第二带宽可以是60个RB。当然，系统带宽也可以有其他取值，如100个RB。相应的，第二带宽为100个RB，本申请实施例对系统带宽的大小不作限定。也就是说，在第一信号配置的带宽为系统带宽的情况下，网络设备为终端设备指示第一信号与通信信号不重叠时的第二带宽。相应的，终端设备基于指示信息2指示的第二带宽来接收第一信号。
示例2，指示信息2指示以下两项：
第一项，第一信号的带宽等于系统带宽。示例性的，仍以系统带宽为60个RB。此种情况下，第一信号的带宽可以是60个RB。当然，系统带宽也可以有其他取值，如100个RB。相应的，第一信号的带宽为100个RB，本申请实施例对系统带宽的大小不作限定。
第二项，网络设备在第二资源上未发送第一信号。此种情况下，若第一信号与通信信号在时域上重叠，则第一资源包括系统带宽中除第二资源之外的频域资源单元。示例性的，仍以系统带宽为60个RB，通信信号的带宽为20个RB。此种情况下，第一资源包括40个RB。当然，系统带宽也可以有其他取值，如100个RB。相应的，第一资源包括80个RB，本申请实施例对系统带宽的大小不作限定。承载通信信号的第二资源用于发送通信信号，而不用于发送第一信号。也就是说，在第一信号与通信信号在时域上重叠的情况下，网络设备301在第二资源上不发送第一信号，在第一资源上向终端设备305发送第一信号。相应的，终端设备305在第二资源上不接收第一信号，在第一资源上接收来自网络设备301的第一信号。若第一信号与通信信号在时域上不重叠，则第一信号占用系统带宽的全部资源。也就是说，在第一信号与通信信号在时域上不重叠的情况下，网络设备301在系统带宽的全带宽上向终端设备305发送第一信号。相应的，终端设备305在系统带宽的全带宽上接收来自网络设备301的第一信号。
示例性的，指示信息(如上述S703中的指示信息1，或S704中的指示信息2)可以是高层信令，比如RRC信令，或者，指示信息也可以是物理层信令，如DCI。
应理解，网络设备301执行S703，不执行S704，相应的，终端设备305执行S703，不执行S704。或者，网络设备301执行S704，不执行S703，相应的，终端设备305执行S704，不执行S703。如此，终端设备305即可基于指示信息1或指示信息2，来接收至少一个第一信号。其中，终端设备305执行S704的情况下，由于终端设备305能够确定第二资源的资源位置，所以，终端设备305基于系统带宽和第二资源的资源位置，来确定第一资源的资源位置，或第一资源所在的位置范围。之后，终端设备305基于第一资源的资源位置，或第一资源所在的位置范围，来接收第一信号。
在S703或S704被执行的情况下，S702具体实现过程可以参见S402a的介绍，此处不再赘述。
需要的说明的是，在网络设备301向终端设备305发送指示信息(如上述S703中的 指示信息1，或S704中的指示信息2)之后，若终端设备305接收到指示信息，终端设备305可以向网络设备301发送ACK或NACK，具体参见信号传输方法400中的介绍。
作为第二种情况，第一信号上未承载通信信息。此种情况下，网络设备301在执行S702之前，无需执行S703和S704。即网络设备301按照第一资源的资源位置传输第一信号即可。
对于网络设备301而言，网络设备301还能够发送通信信号，即网络设备301在第二资源上向终端设备305发送至少一个通信信号。相应的，终端设备305可以在第二资源上接收来自网络设备301的至少一个通信信号。隐式地，网络设备301在第二资源上不向终端设备305发送第一信号。相应的，终端设备305在第二资源上不接收来自网络设备301的第一信号。
也就是说，网络设备采用频分复用的方式传输第一信号和通信信号。
应理解，在本申请实施例信号传输方法400和信号传输方法700中，仅以传输SSB信号的子载波间隔为120kHz为例，进行介绍。当然，子载波间隔还可以替换为其他数值，本申请实施例信号传输方法的核心思想同样适用。在本申请实施例信号传输方法400和信号传输方法700中，系统带宽可以是指NR系统中一个载波支持的带宽。例如，NR系统的载波带宽可以为10MHz、15MHz、20MHz、50MHz、100MHz以及400MHz等中的一种。其中，一个载波可以配置多个部分带宽(bandwidth part，BWP)。当然，系统带宽还可以是指LTE系统中一个服务小区支持的带宽，本申请实施例对此不作限定。
