本申请要求在2020年06月11日提交中国国家知识产权局、申请号为202010531209.6、申请名称为“一种通信方法及装置”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
本申请涉及无线通信技术领域，尤其涉及一种通信方法及装置。
背景技术
非地面通信网络(non-terrestrial network，NTN)具有全球覆盖、远距离传输、组网灵活、部署方便和不受地理条件限制等显著的优点，已经被广泛应用于海上通信、定位导航、抗险救灾、科学实验、视频广播和对地观测等多个领域。
物联网(internet of things，IoT)是信息社会的一个全球基础设施，通过物理和虚拟的物物相连，提供更好的服务。与传统的蜂窝网络面向人与人之间的通信相比，物联网具有覆盖增强、低功耗、低成本和大连接的鲜明特点。因此，将物联网与NTN结合，可以更好地满足物联网终端的业务需求。
现有技术中物联网协议支持以下三种部署模式：1)、独立部署，适用于全球移动通信***(global system for mobile communications，GSM)频段，占用一个GSM频段。2)、保护带部署，利用长期演进计划(long term evolution，LTE)边缘保护带中未使用的带宽资源，部署IoT网络。3)、带内部署，利用LTE载波中间的任何一个资源块(public resource block，PRB)部署IoT网络。
上述三种IoT网络的部署方式均是基于地面蜂窝网络的全频复用设计。然而，如果在NTN IoT网络中采用上述三种部署方式会导致小区边缘所受到的干扰较大，广播信号块难以被可靠接收。
发明内容
本申请提供一种通信方法及装置，用以降低波束间的干扰，保障资源的可靠传输。
第一方面，本申请实施例提供一种通信方法。该方法可以由本申请实施例中的通信装置执行。其中，该通信装置可以是终端设备，或者也可以是类似于终端设备功能的其它装置。该方法中，通信装置可以接收第一信号，并检测第一信号的F个帧，得到第一资源。这里的F可以是复用因子，比如频率/极化复用因子。通信装置可以根据第一资源的帧号，进行检测得到第二资源。其中，第一资源和第二资源可以是相同的资源。
基于该方案，通信装置可以根据网络设备的复用因子对第一信号进行检测，得到第一资源和第二资源。不同的复用因子，通信装置检测得到第一资源和第二资源的帧号不同，就可以降低小区间的干扰，保障信号的可靠传输。
在一种可能的实现方式中，第一资源可以包括以下中的至少一个：窄带主同步信号 (narrowband primary synchronization signal，NPSS)、窄带次同步信号(narrowband secondary synchronization signal，NSSS)、窄带物理广播信道(narrowband physical broadcast channel，NPBCH)。
基于该方案，通信装置可以根据网络设备的复用因子，对第一信号进行检测得到NPSS、NSSS或NPBCH，复用因子不同时，NPSS、NSSS或NPBCH在第一信号的帧号就可能不同，因此通信装置检测的帧号也就会不同，可以降低小区间的干扰，保障NPSS、NSSS或NPBCH的可靠传输。
在一种可能的实现方式中，通信装置可以检测所述第一信号的F个帧，得到所述NPSS。通信装置可以根据NPSS得到NSSS和NPBCH。例如，通信装置可以对第一信号进行盲检，检测第一信号的F个帧，从而得到NPSS。此时，通信装置可以获取到NPSS的帧号等信息，通信装置可以根据NPSS的帧号，确定NSSS和NPBCH的帧号，并对NSSS和NPBCH的帧号进行检测，得到NSSS和NPBCH。
基于该方案，通信装置可以根据NPSS的帧号确定NSSS和NPBCH的帧号，并可以对NSSS和NPBCH的帧号进行检测，得到NSSS和NPBCH。通信装置在检测时就可以根据NPSS、NSSS和NPBCH的帧号的关系进行检测，可以减少通信装置在检测帧号时的复杂度。
在一种可能的实现方式中，NPSS、NSSS和NPBCH在所述第一信号的同一帧。例如，通信装置可以对第一信号进行盲检，检测第一信号的F个帧。此时，通信装置可以获取到NPSS的帧号等信息。通信装置可以检测NPSS的帧号，得到NSSS和NPBCH。其中，NPSS可以携带于子帧5，NSSS可以携带于子帧9，NPBCH可以携带于子帧0。
基于该方案，NPSS、NSSS和NPBCH在第一信号的同一帧，通信装置在检测得到NPSS时，可以对NPSS的帧号进行检测得到NSSS和NPBCH，可以降低通信装置检测帧号时的复杂度。
在一种可能的实现方式中，通信装置可以在第N1+F*N帧上得到第二资源。其中，N1是第一资源的帧号，N为正整数，N＝1，2，…。例如，通信装置检测第一信号的F个帧，从第N1帧上得到了第一资源。因此，通信装置可以检测第N1+F*N帧，得到第二资源。
基于该方案，通信装置在检测第二资源时，可以根据第一资源的帧号对第一信号进行检测，可以不需要对第一信号的每一个帧都进行检测，可以减少通信装置检测的复杂度。另外，由于复用因子的不同，通信装置检测得到第二资源的帧号就不同，可以减少小区之间的干扰。
示例性的，F可以为3或者F为4。例如，通信装置可以检测第一信号的3个帧，在帧0上得到第一资源。通信装置还可以对第一信号进行检测，检测第一信号的第3个帧、第6个帧，第3*N个帧，得到第二资源。
基于该方案，通信装置在检测第一资源时，可以检测第一信号的F个帧得到第一资源，并根据第一资源的帧号N1，在第N1+F*N上进行检测得到第二资源。由于复用因子的不同，通信装置检测得到第二资源的帧号就不同，可以减少小区之间的干扰。
在一种可能的实现方式中，所述复用因子F与所述网络设备的物理小区标识(physical cell indentifier，PCI)相关。例如，每一个PCI可以对应一个复用因子，复用因子相同的PCI在第一信号的F个帧中携带第一资源的帧号可以不相同。举例来说，cell1的复用因子可以是4，并且可以在第一信号的帧0携带第一资源；cell2的复用因子可以是4，并且可 以在第一信号的帧1携带第一资源。
基于该方案，通过网络设备的PCI通信装置可以获取该网络设备的复用因子，从而根据复用因子和第一资源的帧号对第一信号进行检测，得到第二资源。
在一种可能的实现方式中，通信装置可以检测所述第一信号的F个帧的时域符号，得到第一资源。通信装置还可以根据第一资源的帧号和时域符号，对第一信号进行检测得到第二资源。例如，通信装置检测第一信号的F个帧的时域符号，得到第一资源，该第一资源在帧0的时域符号3、4和7上。通信装置可以根据帧0确定第二资源的帧号，并检测第二资源的帧号的时域符号3、4和7，得到第二资源。
基于该方案，可以将第一资源和第二资源进行时域稀释，即仅在指定时域符号上携带第一资源和第二资源，且携带第一资源和第二资源的时域符号可以与复用因子有关，因此可以减少小区之间的信号干扰。
在一种可能的实现方式中，通信装置可以检测所述第一信号的F个帧的子载波，得到第一资源。通信装置还可以根据第一资源的帧号和子载波，对第一信号进行检测得到第二资源。比如，通信装置可以检测第一信号的F个帧的子载波，得到第一资源，该第一资源在帧0的子载波(1、2)上。通信装置可以根据帧0确定第二资源的帧号，并检测第二资源的帧号的子载波(1、2)，得到第二资源。
基于该方案，可以将第一资源和第二资源进行频域稀释，即仅在指定子载波上携带第一资源和第二资源，且携带第一资源和第二资源的子载波可以与复用因子相关，因此可以减少小区之间的信号干扰。
第二方面，本申请实施例还提供一种通信方法。该方法可以由本申请实施例中的网络设备执行，或者是类似于网络设备功能的其他设备执行。该方法中，网络设备可以发送第一信号。其中，第一信号的F个帧上携带第一资源，所述第一信号还携带第二资源，第一资源的帧号与第二资源的帧号相关；所述F为复用因子。
基于该方案，网络设备可以根据复用因子，在第一信号的F个帧上携带第一资源，并根据第一资源的帧号确定携带第二资源的帧号，从而实现不同的复用因子携带第一资源和第二资源的帧号不相同，可以减少小区之间的信号干扰。
在一种可能的实现方式中，所述第一资源可以包括以下中的至少一个：NPSS、NSSS、或NPBCH。应理解，第二资源和第一资源可以是相同的资源，因此第二资源也可以是上述NPSS、NSSS或NPBCH中的至少一个。第一资源和第二资源可以是NPSS、NSSS或NPBCH中的任意一个或者任意组合。
基于该方案，网络设备可以保障NPSS、NSSS或NPBCH的可靠传输，降低在传输NPSS、NSSS或NPBCH时的小区之间的信号干扰。
在一种可能的实现方式中，所述NPSS、所述NSSS和所述NPBCH携带在所述第一信号的同一帧。比如，第一信号的帧0的子帧0可以携带NPBCH，帧0的子帧5可以携带NPSS、帧0的子帧9可以携带NSSS。其中，携带第一资源的子帧可以是协议规定的。
基于该方案，网络设备可以在同一帧上携带NPSS、NSSS和NPBCH，这样可以使得通信装置在检测时检测一个帧就可以得到NPSS、NSSS和NPBCH，可以降低通信装置的检测资源时的复杂度。
在一种可能的实现方式中，在第N1+F*N帧上携带第二资源，其中N1为所述第一资源的帧号，F为复用因子，N为正整数。例如，第一信号的帧A上携带第一资源，因此第 一信号的帧A+F*N上携带第二资源。
基于该方案，网络设备可以根据第一资源的帧号N1，以及上述表达式N1+F*N确定携带第二资源的帧号，使得第二资源的帧号与第一资源的帧号以及复用因子F相关，这样不同的复用因子F携带第二资源的帧号就可以不同，可以降低复用因子F不同的小区之间的信号干扰。
在一种可能的实现方式中，第一资源的帧号N1可以与物理小区标识相关。例如，N1可以与物理小区标识PCI满足以下公式：N1＝PCI mod F，其中mod表示取模操作。举例来说，小区1的PCI为4，小区2的PCI为6，小区1和小区2的复用因子F均为3。因此，可以通过上述公式计算得到小区1的N1_1＝4 mod 3＝1，因此小区1的第一信号的帧1携带第一资源。根据上述公式还可以计算得到小区2的N1_2＝6mod 3＝0，因此小区2的第一信号的帧0携带第一资源。
基于该方案，可以根据网络设备的PCI确定携带第一资源的帧号，由于PCI不同时第一资源的帧号也不相同，因此，第二资源的帧号也可以不相同，可以减少不同的小区之间的信号干扰。
在一种可能的实现方式中，复用因子F可以与网络设备的物理小区标识相关。例如，一个物理小区标识可以绑定一个F，或者多个物理小区标识可以绑定一个F。
基于该方案，复用因子F可以与网络设备的PCI相关，因此不同的小区，F可以不同，就可以降低不同的小区在传输第一资源和第二资源时的信号干扰。
在一种可能的实现方式中，第一信号的F个帧的指定时域符号上携带所述第一资源。因此，第一信号的第N1+F*N帧的指定时域符号上可以携带第二资源。例如，在复用因子F为3时，第一信号的帧0的第3、4时域符号上携带了第一资源，因此第一信号的第0+3*N帧的第3、4时域符号上携带了第二资源。
基于该方案，可以采用时域稀释的方式传输第一资源和第二资源，由于不同的小区传输第一资源和第二资源的时域符号不同，因此可以减少不同的小区在传输第一资源和第二资源时的信号干扰。
在一种可能的实现方式中，第一信号的F个帧的指定子载波上携带所述第二资源。因此，第一信号的第N1+F*N帧的指定子载波上可以携带第二资源。例如，在复用因子F为3时，第一信号的帧0的子载波(1、2)上携带了第一资源，因此第一信号的第0+3*N帧的子载波(1、2)上携带了第二资源。
基于该方案，可以采用频域稀释的方式传输第一资源和第二资源，由于不同的小区传输第一资源和第二资源的子载波不同，因此可以减少不同的小区在传输第一资源和第二资源时的信号干扰。
第三方面，本申请实施例还提供一种通信装置，可以用来执行上述第一方面及第一方面的任意可能的实现方式中的操作。例如，通信装置可以包括用于执行上述第一方面或第一方面的任意可能的实现方式中的各个操作的模块或单元。比如可以包括处理单元和通信单元。

具体实施方式
为了使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请实施例作进一步地详细描述。
以下，首先对本申请实施例中的部分用语进行解释说明，以便于本领域技术人员理解。
1)复用因子F，指每隔F个相邻的网络设备复用相同的频率、极化等维度的资源，其中F＝i^2+ij+j^2，其中i和j为非负整数。
2)帧号，又称***帧号(system frame number，SFN)。例如：任何一个小区的SFN的取值范围可以是从0-4095，每帧SFN加1，当SFN为4095之后，下帧SFN变为0，这样周而复始。又例如：小区的SFN的取值范围可以是从0-1023，每帧SFN加1，当SFN为1023之后，下帧SFN变为0，这样周而复始。其中，小区的SFN的取值可以是根据标准预先定义的，本申请不做具体限定。
需要说明的是，本申请实施例中提及的第一信号的帧号，例如帧0、帧1或帧2等均是示例性的，并不能够代表在实际中第一信号的帧号就是帧0、帧1或帧2。此外，本申请实施例中提及的时域符号1、时域符号2或者时域符号3以及子载波1、子载波2或子载波3等也均是示例性的，并不能够代表实际中时域符号的编号或者子载波的编号。
另外，本申请实施例中，多个，是指两个或两个以上。另外，需要理解的是，在本申请的描述中，“第一”、“第二”等词汇，仅用于区分描述的目的，而不能理解为指示或暗示相对重要性，也不能理解为指示或暗示顺序。
应理解，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被描述为“示例”的任何实施例或实现方案不应被解释为比其它实施例或实现方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
为便于理解本申请实施例，首先以图1中示出的通信***为例详细说明适用于本申请实施例的通信***。图1为本申请适用的一种可能的卫星通信***架构示意图。如果将卫星通信***与地面通信***做类比，可以将卫星看做是地面的一个或多个网络设备，例如基站、接入点1、接入点2、甚至接入点3至接入点n(图中未标出)。卫星向终端设备提供通信服务，卫星还可以连接到核心网设备(例如AMF)。卫星可以为非静止轨道(non-geostationary earth orbit，NGEO)卫星或静止轨道(geostationary earth orbit，GEO)卫星。本申请也可以适用于地面通信***。
卫星基站主要为终端设备提供无线接入服务，调度无线资源给接入的终端设备，提供可靠的无线传输协议和数据加密协议等。卫星基站是指将人造地球卫星和高空飞行器等作为无线通信的基站，例如演进型基站(eNB)和第五代(5th Generation，5G)通信***中的基站(gNB)等。卫星基站可以是静止轨道(geostationary earth orbit，GEO)卫星，也可以是非静止轨道(none-geostationary earth orbit，NGEO)的中轨道(medium earth orbit，MEO)卫星和低轨道(low earth orbit，LEO)卫星，还可以是高空通信平台(High Altitude Platform Station，HAPS)等。卫星设备的运行姿态包括：对地非凝视姿态和对地凝视姿态；其中，对地非凝视姿态的卫星设备发射的卫星波束随着卫星运动，在卫星看来自身发射各波束的角度不会随时间改变，地面固定点在卫星过顶期间会经历较为频繁的波束切换，比如，手电筒模拟卫星轨道绕着地球仪运动，手电筒发射的光束的角度不会改变，同时，由于卫星设备比地球自转的速度还要快，因此除同步卫星外，对于静止轨道的卫星与地球的关系，可以想像为地球静止不动，卫星设备绕着地球做周期性圆周运动。因此，该手电筒 发射的光束能够扫过地球仪一周；而凝视卫星***，卫星发射各波束的角度按一定方式调整，以实现对地面固定点的连续观测。比如，手电筒模拟卫星轨道绕着地球仪运动，在手电筒运行过程中，通过调节发射各光束的角度来实在对同一区域的持续观测(手电筒照亮的区域并不改变)，可以理解的是，该手电筒发射的各光束的角度是可调的。
本申请所述的通信装置可以为终端设备，终端设备包括向用户提供语音和/或数据连通性的设备，具体的，包括向用户提供语音的设备，或包括向用户提供数据连通性的设备，或包括向用户提供语音和数据连通性的设备。例如可以包括具有无线连接功能的手持式设备、或连接到无线调制解调器的处理设备。该终端可以经无线接入网(radio access network，RAN)与核心网进行通信，与RAN交换语音或数据，或与RAN交互语音和数据。该终端可以包括用户设备(user equipment，UE)、无线终端、移动终端、设备到设备通信(device-to-device，D2D)终端、车到一切(vehicle to everything，V2X)终端、机器到机器/机器类通信(machine-to-machine/machine-type communications，M2M/MTC)终端、物联网(internet of things，IoT)终端、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、远程站(remote station)、接入点(access point，AP)、远程终端(remote terminal)、接入终端(access terminal)、用户终端(user terminal)、用户代理(user agent)、或用户装备(user device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端的计算机，便携式、袖珍式、手持式、计算机内置的移动装置等。例如，个人通信业务(personal communication service，PCS)电话、无绳电话、会话发起协议(session initiation protocol，SIP)话机、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(radio frequency identification，RFID)、传感器、全球定位***(global positioning system，GPS)、激光扫描器等信息传感设备。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备或智能穿戴式设备等，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、手环、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能头盔、智能首饰等。
而如上介绍的各种终端，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端，车载终端例如也称为车载单元(on-board unit，OBU)。
本申请实施例中，用于实现终端设备功能的装置可以是终端，也可以是能够支持终端实现该功能的装置，例如芯片***，该装置可以被安装在终端中。本申请实施例中，芯片***可以由芯片构成，也可以包括芯片和其他分立器件。本申请实施例提供的技术方案中，以用于实现终端的功能的装置是终端为例，描述本申请实施例提供的技术方案。
为便于理解本申请实施例，接下来对本请的应用场景进行介绍，本申请实施例描述的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。
如图2所示，目前广播信息的传输方式如下：
窄带主同步信号(narrowband primary synchronization signal，NPSS)：周期10ms，在每个帧的子帧5传输，时域上占用11个符号，频域上占用11个子载波。
窄带次同步信号(narrowband secondary synchronization signal，NSSS)：周期20ms，在每个偶数帧(如图1中的帧0、帧8等)的子帧9传输，时域上占用11个符号，频域上占用整个物理资源块(physical resource block，PRB)带宽，即12个子载波。
窄带物理广播信道(narrowband physical broadcast channel，NPBCH)：周期640ms，在每个帧的子帧0传输，时域上占用11个符号，频域上占用整个PRB带宽，即12个子载波。在一个周期内，NPBCH分为8个传输块传输，其中每一个传输块的内容不同。每个传输块的内容连续重复传输8次后，再传输下一个传输块。如图1所示，从帧0-帧7可以传输第一传输块，帧8-帧15可以传输第二传输块，以此类推，将NPBCH的8个传输块全部传输。
可见，现有的广播信息的传输方法是全频复用方法。然而，在卫星通信网络中，一个卫星中配置多个波束，每个波束可以看作是一个小区中的波束或一个单独的小区。由于卫星波束的中心位置与边缘位置的信号强度差别不大，若采用全频复用的方式进行通信，则相邻波束间会产生强干扰。因此，在卫星通信***中，通常采用多色复用(包含频率复用和极化复用)的方式来减少卫星波束之间的干扰。例如，在时间单元T1内，0、1、4、5四个波束对应的频段不同，例如可以将***带宽等分为四个频段，每个频段的中心频点分别为f1、f2、f3和f4，则波束0、1、4、5分别对应中心频点分别为f1、f2、f3和f4的频段。卫星中相邻的波束使用不同的频率与终端设备进行通信，从而达到抑制干扰的效果。
但是，若采用上述的多色复用的方式，采用不同的频率传输广播信息，小区与小区之间的广播信息的传输可能还是会存在强干扰，可能无法保证广播信息的可靠传输。
有鉴于此，本申请实施例提供一种通信方法，本申请实施例的技术方案可以应用于各种通信***，例如：地面通信***，非地面通信***，例如卫星通信***。其中，所述卫星通信***可以与传统的移动通信***相融合。例如：所述移动通信***可以为***(4th Generation，4G)通信***(例如，长期演进(long term evolution，LTE)***)，物联网通信***、全球互联微波接入(worldwide interoperability for microwave access，WiMAX)通信***，5G通信***(例如，新无线(new radio，NR)***)，及未来的移动通信***等。
本申请将围绕可包括多个设备、组件、模块等的***来呈现各个方面、实施例或特征。应当理解和明白的是，各个***可以包括另外的设备、组件、模块等，并且/或者可以并不包括结合附图讨论的所有设备、组件、模块等。此外，还可以使用这些方案的组合。
本申请实施例描述的网络架构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。
以下，不失一般性的，以通信装置为终端设备为例介绍本申请实施例提供的通信方法。应理解，本申请实施例中的通信装置还可以是类似于终端设备功能的其它设备。其它设备在与网络设备进行通信时，也可以本申请实施例提供的通信方法与网络设备进行通信。图 3是从设备交互的角度示出的本申请实施例提供的通信方法的示例性流程图。如图3所示，该方法可以包括：
步骤301：网络设备发送第一信号。相应的，终端设备接收第一信号。
第一信号可以在F个帧上携带有第一资源。其中，可以在第一信号的帧0至帧f中的一个帧上携带第一信号。如图4所示，第一信号的帧0至帧3的四个帧中的帧1上携带有第一资源。
另外需要说明的是，网络设备的复用因子F是预先配置的。例如，可以将复用因子F与网络设备的物理小区标识(physical cell identifier，PCI)绑定。一个PCI可以绑定一个复用因子F或者多个PCI可以绑定一个复用因子F。或者，还可以将复用因子F与网络设备的唯一标识绑定，一个唯一标识可以绑定一个复用因子F或者多个唯一标识可以绑定一个复用因子F。此外，网络设备的复用因子F还可以是根据标准预定义的。
其中，复用因子F相同且相邻的网络设备的第一信号中携带第一资源的帧号可以是不同的。如图5所示，小区1、小区2和小区3的复用因子F皆为3，且小区1与小区2相邻，小区2与小区3相邻。其中，小区1的第一信号中帧0携带了第一资源，小区2的第一信号中帧1携带了第一资源，小区3的第一信号中帧2携带了第一资源。应理解，每隔F个相邻的网络设备的第一信号中携带第一资源的帧号可以是相同的。比如，小区1与小区2相邻，小区2与小区3相邻，小区3与小区4相邻，小区4与小区5相邻，小区5与小区6相邻。其中，小区1-小区6的复用因子F均为3。因此，小区1与小区4的第一信号中携带第一资源的帧号可以是相同的，比如可以在帧0携带第一资源。小区2与小区5的第一信号中携带第一资源的帧号可以是相同的，比如可以在帧1携带第一资源。小区3与小区6的第一信号中携带第一资源的帧号可以是相同的，比如可以在帧2携带第一资源。
本申请实施例中第一信号还可以携带第二资源，第二资源的帧号与第一资源相关。应理解，第二资源与第一资源可以是相同的资源。
以下具体介绍第一信号携带第一资源和第二资源的实现方式。
如果第一信号的第N1帧上携带第一资源，则第一信号的第N1+F*N帧上携带第二资源。其中，N＝1,2，…。例如，第一信号的第N1帧上携带第二资源，第一信号的第N1+F帧、第N1+2F帧、第N1+3F帧…第N1+F*N帧上都可以携带有第二资源。
其中，第一资源的帧号N1可以是预先配置的。例如，可以将第一资源的帧号N1与网络设备的唯一标识绑定，一个唯一标识可以绑定一个N1，或者多个唯一标识可以绑定一个N1。或者，第一资源的帧号N1可以是根据标准预定义的。又或者，第一资源的帧号N1还可以与前述PCI相关。例如，N1与PCI可以满足如下关系：
N1＝PCI mod F，其中mod表示取模操作。如图5所示，图5中的小区1的PCI为6，小区2的PCI为4，小区3的PCI为5。根据上述公式可以计算得到小区1的N1_1＝6mod3＝0，小区2的N1_2＝4 mod 3＝1，小区3的N1_3＝5 mod 3＝2。因此，如图5所示，小区1的第一信号的帧0可以携带第一资源，小区2的第一信号的帧1可以携带第一资源，小区3的第一信号的帧2可以携带第一资源。应理解，上述PCI的取值是示例性的，小区的PCI还可以是其他的值，本申请不做具体限定。
参阅图6，小区1、小区2、小区3和小区4的复用因子F均为4，且小区1与小区2相邻，小区2与小区3相邻，小区3与小区4相邻。其中，小区1的第一信号的帧0携带第一资源，那么小区1的第一信号的第0+4*1帧，即帧4上携带第二资源，第0+4*2帧， 即帧8上携带第二资源，以此类推，小区1的第一信号的帧12(图中未示出)、帧16(图中未示出)，帧0+4*N上携带第二资源。小区2的第一信号的帧1携带第一资源，那么小区2的第一信号的第1+4*1帧，帧5上携带第二资源，以此类推，小区2的第一信号的帧9(图中未示出)、帧13(图中未示出)、帧17(图中未示出)，帧1+4*N上携带第二资源。小区3的第一信号的帧2携带第一资源，第2+4*1帧，即帧6上携带第二资源，以此类推，小区3的第一信号的帧10(图中未示出)、帧14(图中未示出)携带第二资源。小区4的第一信号的帧3携带第一资源，那么小区4的第一信号的第3+4*1帧，即帧7上携带第二资源，以此类推，小区4的第一信号的帧11、帧15，帧3+4*N上携带第二资源。
参阅图7，小区1、小区2和小区3的复用因子F均为3，且小区1与小区2相邻，小区2与小区3相邻。其中，小区1的第一信号的帧0携带第一资源，那么小区1的第一信号的第0+3*1帧，即帧3携带第二资源，小区1的第一信号的第0+3*2帧，帧6携带第二资源，以此类推，小区1的第一信号的第0+3*N帧携带第二资源。小区2的第一信号的帧1携带第一资源，那么小区2的第一信号的第1+3*1帧，即帧4携带第二资源，小区2的第一信号的第1+3*2帧，即帧7携带第二资源，以此类推，小区2的第一信号的第1+3*N帧携带第二资源。小区3的第一信号的帧2携带第一资源，那么小区3的第一信号的第2+3*1帧，即帧5携带第二资源，小区3的第一信号的第2+3*2帧，即帧8携带第二资源，以此类推，小区3的第一信号的第2+3*N帧携带第二资源。
另外需要说明的是，前述的第一资源和第二资源可以是窄带主同步信号(narrowband primary synchronization signal，NPSS)、窄带次同步信号(narrowband secondary synchronization signal，NSSS)或窄带物理广播信道(narrowband physical broadcast channel，NPBCH)中的任意一个或任意组合。应理解，携带第一资源和第二资源的子帧可以是协议规定的，或者也可以是网络设备指示的。比如，网络设备可以通过第一指示信息指示NPSS、NSSS和NPBCH分别携带于哪一子帧上。
参阅图8A-图8D，分别示出了复用因子F为4的多个小区的第一信号。其中，小区1与小区2相邻，小区2与小区3相邻，小区3与小区4相邻。如图8A所示，小区1的第一信号的帧0携带第一资源。其中，帧0的子帧0携带NPBCH(具体对应NPBCH第一数据块，即NPBCH Block1)，帧0的子帧5携带NPSS，帧0的子帧9携带NSSS。因此，小区1的第一信号的第0+4*N帧，即帧4N可以携带第二资源。考虑到NPBCH、NPSS和NSSS的周期性不同，本实施方式中，帧4N的子帧0携带NPBCH，帧4N的子帧5携带NPSS，帧4*2*N的子帧9携带NSSS。可以看出，F＝4时，帧长为10ms，对应的NPBCH、NPSS和NSSS的周期分别为2560ms、40ms和80ms。
参阅图8B，小区2的第一信号的帧1携带第一资源。其中，帧1的子帧0携带NPBCH，帧1的子帧5携带NPSS，帧1的子帧9携带NSSS。因此，小区2的第一信号的第1+4*N帧，即帧1+4*N可以携带第二资源。其中，帧1+4*N的子帧0携带NPBCH，帧1+4*N的子帧5携带NPSS，帧1+4*2*N的子帧9携带NSSS。
参阅图8C，小区3的第一信号的帧2携带第一资源。其中，帧2的子帧0携带NPBCH，帧2的子帧5携带NPSS，帧2的子帧9携带NSSS。因此，小区3的第一信号的第2+4*N帧，即帧2+4*N可以携带第二资源。其中，帧2+4*N的子帧0携带NPBCH，帧2+4*N的子帧5携带NPSS，帧2+4*2*N的子帧9携带NSSS。
参阅图8D，小区4的第一信号的帧3携带第一资源。其中，帧3的子帧0携带NPBCH， 帧3的子帧5携带NPSS，帧3的子帧9携带NSSS。因此，小区4的第一信号的第3+4*N帧，即帧3+4*N可以携带第二资源。其中，帧3+4*N的子帧0携带NPBCH，帧3+4*N的子帧5携带NPSS，帧3+4*2*N的子帧9携带NSSS。
参阅图9A-图9C，分别示出了复用因子F为3的多个小区的第一信号。其中，小区1与小区2相邻，小区2与小区3相邻。如图9A所示，小区1的第一信号的帧0携带第一资源。其中，帧0的子帧0携带NPBCH(具体对应NPBCH第一数据块，即NPBCH Block1)，帧0的子帧5携带NPSS，帧0的子帧9携带NSSS。因此，小区1的第一信号的第0+3*N帧，即帧3N携带第二资源。考虑到NPBCH、NPSS和NSSS的周期性不同，本实施方式中，帧3N的子帧0携带NPBCH，帧3N的子帧5携带NPSS，帧3*2*N的子帧9携带NSSS。
参阅图9B，小区2的第一信号的帧1携带第一资源。其中，帧1的子帧0携带NPBCH，帧1的子帧5携带NPSS，帧1的子帧9携带NSSS。因此，小区2的第一信号的第1+3*N帧，即帧1+3*N携带第二资源。其中，帧1+3*N的子帧0携带NPBCH，帧1+3*N的子帧5携带NPSS，帧1+3*2*N的子帧9携带NSSS。
参阅图9C，小区3的第一信号的帧2携带第一资源。其中，帧2的子帧0携带NPBCH，帧2的子帧5携带NPSS，帧2的子帧9携带NSSS。因此，小区3的第一信号的第2+3*N帧，即帧2+3*N携带第二资源。其中，帧2+3*N的子帧0携带NPBCH，帧2+3*N的子帧5携带NPSS，帧2+3*2*N的子帧9携带NSSS。
如图8A-8D和9A-9C所示，NPBCH、NPSS和NSSS均在第一信号的同一帧上。在本申请实施例中，NPBCH、NPSS和NSSS也可以在第一信号的不同帧上。如图10所示，示出了复用因子F为4的小区的第一信号。其中，小区1的第一信号的帧0携带NPBCH。因此，小区1的第一信号的第0+4*1帧，帧4携带NPBCH。以此类推，小区1的第一信号的第0+4N帧，即帧4N携带NPBCH。
如图10所示，小区1的第一信号的帧0和帧1携带NPSS。因此，小区1的第一信号的第0+4*2帧，即帧8携带NPSS，以及第1+4*2帧，即帧9也携带NPSS。其中，由于第一信号的F个帧中的两个帧携带了第一资源，因此，小区1的第N1+F*N帧中的N应该是(N+1)，即小区1的第一信号的第N1+F*(N+1)帧携带第二资源。以此类推，如果第一信号的F个帧中的三个帧携带了第一资源，那么小区1的第一信号的第N1+F*(N+2)帧携带第二资源，如果第一信号的F个帧中的M个帧携带了第一资源，那么小区1的第一信号的第N1+F*(N+M-1)帧可以携带第二资源。其中，M为正整数。如图10所示，小区1的第一信号的帧1携带NSSS。因此，考虑到NSSS的周期性，小区1的第一信号的第1+4*2帧，即帧9携带NSSS。
另外需要说明的是，在非地面通信***，例如卫星通信***中，卫星的波束可以对应于前述的网络设备的小区。参阅图11，图11示出了8波束卫星***示意图。其中，波束1-波束8的复用因子F为4，波束1和波束2的第一信号中携带第一资源的帧可以是相同的，波束3和波束4的第一信号中携带第一资源的帧可以是相同的，波束5和波束6的第一信号中携带第一资源的帧可以是相同的，波束7和波束8的第一信号中携带第一资源的帧可以是相同的。
在本申请实施例中，可以通过时域稀释的方式在第一信号中携带第一资源，例如第一信号的F个帧上的指定时域符号上携带第一资源。
举例来说，NPSS在第S1＝(3、4、5、6、9、10、11)时域符号上传输的内容相同， 在第S2＝(7、8、12)时域符号上传输的内容相同。因此，可以将第S1时域符号和第S2时域符号进行组合，在F个帧的指定时域符号上携带第一资源。例如，在复用因子F为3时，小区1可以在第一信号的帧A的第3、4、7时域符号上携带第一资源，小区2可以在第一信号的帧B的第5、6、8时域符号上携带第一资源，小区3可以在第一信号的帧C的第9、10、12时域符号上携带第一资源。那么，同样的小区1的可以在帧A+3*N的第3、4、7时域符号上携带第二资源。小区2可以在第一信号的帧B+3*N的第5、6、8时域符号上携带第二资源，小区3可以在第一信号的帧C+3*N的第9、10、12时域符号上携带第二资源。
可选的，本申请实施例还可以将上述时域稀释方式和现有技术的第一资源的传输方法相结合。如图2所示，每一个帧的一个子帧上可以有多个时域符号。网络设备可以在第一信号的第一帧的指定时域符号上，即帧0的指定时域符号上可以携带第一资源。在复用因子F为3时，小区1可以在第一信号的第一帧的第3、4、7时域符号上携带第一资源，小区2可以在第一信号的第一个帧的第5、6、8时域符号上携带第一资源，小区3可以在第一信号的第一个帧的第9、10、12时域上携带第一资源。因此，小区1可以在除第一帧以外的每一个帧的第3、4、7时域符号上携带第二资源，小区2可以在除第一帧以外的每一个帧的第5、6、8时域符号上携带第二资源，小区3可以在除第一帧以外的每一个帧的第9、10、12时域符号上携带第二资源。应理解，在第一信号的除第一帧以外的其他上携带第二资源时，应考虑第二资源的周期性。
在另一个可能实现的方式中，还可以通过频域稀释的方式在第一信号中携带第一资源，例如第一信号的F个帧上的指定子载波上携带第一资源。
举例来说，NPSS在频域上占用11个子载波，因此可以通过频域稀释的方式减少NPSS的传输带宽。例如，参阅图6，每一个帧的一个子帧上有多个子载波。在复用因子F为4时，小区1可以在帧0的子载波(1、2)上携带第一资源，小区2可以在帧1的子载波(4、5)上携带第一资源，小区3可以在帧2的子载波(7、8)上携带第一资源，小区4可以在帧3的子载波(10、11)上携带第一资源。
因此，同样的小区1可以在帧4*N的子载波(1、2)上携带第二资源，小区2可以在帧1+4*N的子载波(4、5)上携带第二资源，小区3可以在帧2+4*N的子载波(7、8)上携带第二资源，小区4可以在帧3+4*N的子载波(10、11)上携带第二资源。
又例如，NSSS占用频域上的12个子载波，因此也可以通过频域稀释的方式减少NSSS的传输带宽。例如，参阅图5，每一个帧的一个子帧上有多个子载波。在复用因子F为3时，小区1可以在帧0的子载波(1、4、7、10)上携带第一资源，小区2可以在帧1的子载波(2、5、8、11)上携带第一资源，小区3可以在帧2的子载波(3、6、9、10)上携带第一资源。因此，同样的小区1可以在帧3*N的子载波(1、4、7、10)上携带第二资源，小区2可以在帧1+3*N的子载波(2、5、8、11)上携带第二资源，小区3可以在帧2+3*N的子载波(3、6、9、10)上携带第二资源。
在一个示例中，网络设备可以将上述时域稀释和频域稀释的方法相结合传输第一资源和第二资源。例如，在小区1的复用因子F为3时，小区1的第一信号的帧A的第3、4、7时域符号和子载波(1,2)上携带第一NPSS，在第一信号的帧A+3*N的第3、4、7时域符号和子载波(1,2)上携带第二NPSS。
可选的，本申请实施例还可以将上述频域稀释与现有技术的第一资源的传输方法相结 合。如图2所示，每一个帧的一个子帧上有多个子载波和多个时域符号。网络设备可以在第一信号的第一个帧上的指定子载波携带第一资源。举例来说，在复用因子F为3时，小区1可以在第一信号的第一帧的子载波(1、4、7、10)上携带第一资源，小区2可以在第一帧的子载波(2、5、8、11)上携带第一资源，小区3可以在第一帧的子载波(3、6、9、10)上携带第一资源。因此，小区1可以在第一信号的除第一帧以外的每一个帧的子载波(1、4、7、10)上携带第二资源，小区2可以在第一信号的除第一帧以外的每一个帧的子载波(2、5、8、11)上携带第二资源，小区3可以在第一信号的除第一帧以外的每一个帧的子载波(3、6、9、10)上携带第二资源。
步骤302：所述终端设备检测所述第一信号的F个帧，得到第一资源。
这里的F可以是网络设备的复用因子。其中，终端设备可以对第一信号的帧0至帧f的F个帧进行检测，得到第一资源。如图4所示，终端设备对第一信号的帧0至帧3的四个帧进行检测，得到了第一资源，其中第一资源的帧号为帧1。
另外需要说明的是，F是网络设备的复用因子。不同的网络设备可以有相同的复用因子F或者不同的网络设备可以有不同的复用因子F。例如，可以将复用因子F与网络设备的物理小区标识(physical cell identifier，PCI)绑定。一个PCI可以绑定一个复用因子F或者多个PCI可以绑定一个复用因子F。因此，终端设备可以获取网络设备的PCI，并确定网络设备的复用因子F，从而检测第一信号的F个帧，得到第一资源。这里的PCI可以是网络设备发送给终端设备的。其中，PCI可以与第一信号使用相同的信令发送，或者PCI也可以与第一信号使用不同的信令发送。
其中，上述第一资源可以是NPSS、NSSS和NPBCH中的任意一个或者任意组合。在一个示例中，终端设备可以检测第一信号，得到NPSS。其中，该NPSS中可以包括网络设备的物理小区标识PCI，因此终端设备可以根据该PCI确定网络设备的复用因子F，终端设备可以检测第一信号的F个帧，得到NSSS和/或NPBCH。如图10所示，终端设备对第一信号进行检测，在帧0和帧1得到了NPSS。终端设备可以根据该NPSS确定网络设备的复用因子F为4，因此终端设备可以检测第一信号的4个帧，在帧0得到NPBCH，在帧1得到NSSS。
在另一示例中，NPSS、NSSS和NPBCH可以在第一信号的同一帧，因此终端设备可以对第一信号进行检测，得到NPSS、NSSS和NPBCH。应理解，携带NPSS、NSSS和NPBCH的子帧可以是协议规定的，如图8A所示，终端设备可以对第一信号的F个帧进行检测，在帧0的子帧0得到NPBCH，在帧0的子帧5得到NPSS，在帧0的子帧9得到NSSS。
步骤303：所述终端设备根据所述第一资源的帧号，进行检测得到第二资源。
这里的第二资源可以与第一资源相同。以下具体介绍根据第一资源的帧号，进行检测得到第二资源的实现方式。
如果终端设备对第一信号进行检测得到了第一资源，该第一资源的帧号是N1，那么终端设备可以检测第一信号的第N1+F*N帧得到第二资源。其中，N＝1,2，…。例如，第一资源的帧号是N1，终端设备可以检测第一信号的第N1+F帧、第N1+2F帧、第N1+3F帧…第N1+F*N帧，得到第二资源。
参阅图6，终端设备接收小区1发送的第一信号，终端设备可以检测第一信号的4个帧，得到第一资源。该第一资源的帧号为帧0。因此，终端设备可以检测第一信号的第0+4*1 帧，即帧4、第0+4*2帧，即帧8进行检测得到第二资源。以此类推，终端设备还可以检测第一信号的帧12(图中未示出)、帧16(图中未示出)、帧0+4*N，得到第二资源。如果终端设备接收小区2发送的第一信号，终端设备可以检测第一信号的4个帧，得到第一资源。该第一资源的帧号为帧1。因此，终端设备可以检测第一信号的第1+4*1帧，即帧5、第1+4*2帧，即帧9(图中未示出)，得到第二资源。以此类推，终端设备可以检测第一信号的帧13(图中未示出)、帧17(图中未示出)，帧1+4*N，得到的第二资源。如果终端设备接收小区3发送的第一信号，终端设备可以检测第一信号的4个帧，得到第一资源。该第一资源的帧号为帧2。因此，终端设备可以检测第一信号的第2+4*1帧，即帧6、第2+4*2帧，即帧10(图中未示出)，得到第二资源。以此类推，终端设备可以检测第一信号的帧14(图中未示出)、帧18(图中未示出)、帧2+4*N，得到第二资源。如果终端设备接收下小区4发送的第一信号，终端设备可以检测第一信号的4个帧，得到第一资源。该第一资源的帧号为帧3。因此，终端设备可以检测第一信号的第3+4*1帧，即帧7得到第二资源。以此类推，终端设备还可以检测第一信号的帧11(图中未示出)、帧15(图中未示出)、帧3+4*N，得到第二资源。
参阅图7，如果终端设备接收小区1发送的第一信号，终端设备可以检测第一信号的3个帧，得到第一资源。该第一资源的帧号为帧0。因此，终端设备可以检测第一信号的第0+3*1帧，即帧3、第0+3*2帧，即帧6，得到第二资源。以此类推，终端设备还可以检测第一信号的帧9、帧12、帧3N得到第二资源。如果终端设备接收小区2发送的第一信号，终端设备可以检测第一信号的3个帧，得到第一资源。该第一资源的帧号为帧1。因此，终端设备可以检测第一信号的第1+3*1帧，即帧4、第1+3*2帧，即帧7，得到第二资源。以此类推，终端设备还可以检测第一信号的帧10、帧13，帧1+3*N得到第二资源。如果终端设备接收小区3发送的第一信号，终端设备可以检测第一信号的3个帧，得到第一资源。该第一资源的帧号为帧2。因此，终端设备可以检测第一信号的第2+3*1帧，即帧5，第2+3*2帧，即帧8，得到第二资源。以此类推，终端设备还可以检测第一信号的帧11、帧15、帧2+3*N，得到第二资源。
其中，前述的第一资源和第二资源可以是NPSS、NPBCH或NSSS中的任意一个或者任意组合。应理解，携带第一资源和第二资源的子帧可以是协议规定的，或者也可以是网络设备指示的。比如，网络设备可以通过第一指示信息指示NPSS、NSSS和NPBCH分别携带于哪一子帧上。
参阅图8A，终端设备接收小区1发送的第一信号。终端设备检测小区1的4个帧，得到第一资源。其中，帧0的子帧0携带NPBCH，帧0的子帧5携带NPSS，帧0的子帧9携带NSSS。因此，终端设备可以检测第一信号的第0+4*1帧，即帧4得到第二资源。考虑到NPBCH、NPSS和NSSS的周期性不同，本实施方式中，帧4N的子帧0携带NPBCH，帧4N的子帧5携带NPSS，帧4*2*N的子帧9携带NSSS。可以看出，F＝4时，帧长为10ms，对应的NPBCH、NPSS和NSSS的周期分别为2560ms、40ms和80ms。
参阅图9A，终端设备可以接收小区1发送的第一信号。终端设备可以检测小区1的3个帧，得到第一资源。其中，帧0的子帧0携带NPBCH，帧0的子帧5携带NPSS，帧0的子帧9携带NSSS。因此，终端设备可以检测第一信号的第0+3*1帧，即帧3得到第二资源。其中，帧3的子帧0携带NPBCH，帧3的子帧5携带NPSS，帧3的子帧9携带NSSS。以此类推，终端设备还可以检测第一信号的第0+3*N帧得到第二资源。考虑到 NPBCH、NPSS和NSSS的周期性不同，本实施方式中，帧3N的子帧0携带NPBCH，帧3N的子帧5携带NPSS，帧3*2*N的子帧9携带NSSS。
如图8A-8D和9A-9C所示，NPBCH、NPSS和NSSS均在第一信号的同一帧上。在本申请实施例中，NPBCH、NPSS和NSSS也可以在第一信号的不同帧上。如图10所示，终端设备接收小区1发送的第一信号。终端设备检测该第一信号的4个帧，得到了NPBCH。该NPBCH的帧号为帧0，因此终端设备可以检测第一信号的第0+4*1帧，即帧4得到NPBCH。以此类推，终端设备可以检测第一信号的帧8、帧12、帧4*N得到NPBCH。
如图10所示，终端设备检测第一信号的4个帧，得到NPSS。其中，该NPSS的帧号为帧0和帧1。其中，由于第一信号的4个帧中的两个帧携带了NPSS，因此，终端设备可以检测第一信号的第0+4*2帧，即帧8得到NPSS，以及检测第一信号的第1+4*2帧，即帧9得到NPSS。以此类推，如果第一信号的F个帧中M个帧携带了NPSS，终端设备可以检测第一信号的第N1+F*(N+M-1)帧得到NPSS。其中，M为正整数。如图10所示，终端设备可以检测第一信号的4个帧，得到NSSS。其中该NSSS的帧号为帧1。因此，考虑到NSSS的周期性，终端设备可以检测第一信号的第1+4*2帧，即帧9、第1+F*2*N帧得到NSSS。
在本申请实施例中，可以通过时域稀释的方式检测第一信号得到第一资源。例如，终端设备可以检测F个帧上的指定时域符号得到第一资源。
举例来说，NPSS在第S1＝(3、4、5、6、9、10、11)时域符号上传输的内容相同，在第S2＝(7、8、12)时域符号上传输的内容相同。因此，网络设备可以将第S1时域符号和第S2时域符号进行组合，在F个帧的指定时域符号上携带第一资源。终端设备在检测第一信号时，也可以在F个帧上的指定时域符号上得到第一资源。例如，在复用因子F为3时，小区1可以在第一信号的帧A的第3、4、7时域符号上携带第一资源。终端设备可以检测F个帧的第3、4、7时域符号得到第一资源。终端设备还可以检测第一信号的第A+3*N帧的第3、4、7时域符号得到第二资源。
可选的，如图2所示，第一信号的每一个帧的一个子帧上可以有多个时域符号。终端设备还可以检测第一信号的第一帧的指定时域符号得到第一资源，检测第一信号的除第一帧以外的每一个帧的指定时域符号得到第二资源。举例来说，在复用因子F为3时，终端设备可以检测第一信号的第一帧的第3、4、7时域符号得到第一资源，检测第一信号的除第一帧以外的每一个帧的第3、4、7时域符号得到第二资源。
在另一个可能的实现方式中，终端设备还可以通过频域稀释的方式检测第一信号得到第一资源。例如，终端设备可以检测F个帧上的指定子载波得到第一资源。
举例来说，NPSS在频域上占用11个子载波，因此可以通过频域稀释的方式减少NPSS的传输带宽。例如，在复用因子F为4时，终端设备可以检测帧A的子载波(1、2)得到第一资源。因此，终端设备可以检测帧A+4*N的子载波(1、2)得到第二资源。或者，复用因子F为4时，终端设备可以检测帧B的子载波(4、5)得到第一资源。因此，终端设备可以检测帧B+4*N的子载波(4、5)得到第二资源。又例如，NSSS在频域上占用12个子载波，也可以通过频域稀释的方式减少NSSS的传输带宽。例如，复用因子F为3时，终端设备可以检测帧A的子载波(1、4、7、10)得到第一资源。因此，终端设备可以检测帧A+3*N的子载波(1、4、7、10)得到第二资源。
在一个示例中，终端设备还可以检测第一信号的F个帧的指定时域符号和指定子载波 得到第一资源。举例来说，在复用因子F为3时，终端设备可以在帧A的第3、4、7时域符号上和在子载波(1、2)上检测得到第一NPSS。终端设备还可以在帧A*3*N的第3、4、7时域符号和在子载波(1、2)上检测得到第二NPSS。
可选的，如图2所示，第一信号的每一个帧的一个子帧上可以有多个子载波。终端设备还可以检测第一信号的第一帧的指定子载波得到第一资源，检测第一信号的除第一帧以外的每一个帧的指定子载波得到第二资源。举例来说，在复用因子F为4时，终端设备可以检测第一信号的第一帧的子载波(1、2)得到第一资源，终端设备还可以检测第一信号的除第一帧以外的每个帧的子载波(1、2)得到第二资源。
在一示例中，终端设备还可以将时域稀释和频域稀释相结合，传输第一资源和第二资源。如图2所示，终端设备还可以检测第一信号的第一帧的指定时域符号和指定子载波得到第一资源，检测第一信号的除第一帧以外的每一个帧的指定时域符号和指定子载波得到第二资源。举例来说，在复用因子F为3时，终端设备可以检测第一信号的第一帧的第3、4、7时域符号和子载波(1、2)得到第一NPSS，终端设备还可以检测第一信号的除第一帧以外的每一个帧的第3、4、7时域符号和子载波(1、2)得到第二NPSS。

当通信装置为终端设备时，图14示出了一种简化的终端设备的结构示意图。便于理解和图示方便，图14中，终端设备以手机作为例子。如图14所示，终端设备包括处理器、存储器、射频电路、天线以及输入输出装置。处理器主要用于对通信协议以及通信数据进行处理，以及对终端设备进行控制，执行软件程序，处理软件程序的数据等。存储器主要用于存储软件程序和数据。射频电路主要用于基带信号与射频信号的转换以及对射频信号的处理。天线主要用于收发电磁波形式的射频信号。输入输出装置，例如触摸屏、显示屏，键盘等主要用于接收用户输入的数据以及对用户输出数据。需要说明的是，有些种类的终端设备可以不具有输入输出装置。
当需要发送数据时，处理器对待发送的数据进行基带处理后，输出基带信号至射频电路，射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发送。当有数据发送到终端设备时，射频电路通过天线接收到射频信号，将射频信号转换为基带 信号，并将基带信号输出至处理器，处理器将基带信号转换为数据并对该数据进行处理。为便于说明，图14中仅示出了一个存储器和处理器。在实际的终端设备产品中，可以存在一个或多个处理器和一个或多个存储器。存储器也可以称为存储介质或者存储设备等。存储器可以是独立于处理器设置，也可以是与处理器集成在一起，本申请实施例对此不做限制。
