Description

信号传输的方法、网络设备和终端设备 技术领域
本申请实施例涉及通信领域，并且更具体地，涉及信号传输的方法、网络设备和终端设备。
背景技术
在免授权频谱上，通信设备遵循“先听后说(Listen Before Talk，LBT)”原则，即通信设备在免授权频谱的信道上进行信号发送前，需要先进行信道检测，只有当信道检测结果为信道空闲时，或者说，获得信道使用权时，该通信设备才能进行信号发送；如果通信设备在免授权频谱的信道上的信道检测结果为信道忙，该通信设备不能进行信号发送。
在新无线(New Radio，NR)中，同步信号块(Synchronization Signal Block，SSB)为用于终端设备接入网络和进行无线资源管理(Radio Resource Management，RRM)测量的重要的信号，将免授权频谱应用到NR***上时，网络设备必须获得信号使用权才能发送SSB，此情况下，网络设备如何有效传输SSB是一项值得研究的问题。
发明内容
本申请实施例提供了一种信号传输的方法、网络设备和终端设备，能够根据信道检测结果实现SSB的有效传输。
第一方面，提供了一种信号传输的方法，包括：网络设备对第一载波进行检测，并根据检测结果从M1个时频资源中确定获得信道使用权的第一时频资源，所述M1个时频资源是所述网络设备为所述第一载波上的第一周期配置的可用于传输第一同步信号块SSB的时频资源，M1为正整数，M1≥2；所述网络设备通过所述第一时频资源向终端设备发送所述第一SSB。
因此，在本申请实施例中，网络设备可以在第一周期内配置可用于传输该第一SSB的多个时频资源，有利于增加SSB的发送机会，并且该网络设备在该第一周期内可以对第一载波进行信道检测，根据信道检测结果确定在该第一周期内的M1个时频资源中可用的第一时频资源，进一步地可以通过该第一时频资源发送该第一SSB，而不是在该M1个时频资源中的每个时频资源或特定时频资源上发送第一SSB，能够实现该第一SSB的有效传输，并且有利于提升资源利用效率。
应理解，该M1个时频资源可用于传输该第一SSB，或者，该M1个时频资源可以认为是可用于传输第一SSB的候选时频资源，但是，在实际传输中，该M1个时频资源不一定都用于传输该第一SSB，因此，该M1个时频资源可以包括实际传输第一SSB的时频资源和未传输第一SSB的时频资源。
可选地，若在该M1个时频资源上都信道检测失败，即未获得该M1个时频资源中的任一时频资源的信道使用权，则该网络设备可以不在该第一周期内进行该第一SSB的发送，进一步的，该网络设备可以在该第一周期之后的第二周期内对该第一载波进行信道检测，并根据该第二周期内的信道检测结果进行该第一SSB的发送。
可选地，在本申请实施例中，该第一载波可以为免授权载波，或者也可以为授权载波，本申请实施例对此不作限定。
可选地，在本申请实施例中，所述第一周期的长度可以是通信***规定的，或者也可以是网络设备配置的，或者可以是网络设备和终端设备共同确定的，本申请实施例并不限定该第一周期的确定方式。
在一些可能的实现方式中，所述网络设备在所述第一周期内发送所述第一SSB的最大次数为N1，N1为正整数，1≤N1＜M1。
因此，网络设备可以只在M1个时频资源中的部分时频资源上发送该第一SSB，而不是在该M1个时频资源中的每个时频资源上都发送第一SSB，能够降低SSB的发送次数，从而能够降低用于SSB发送的资源开销。
可选地，该N1的取值可以是由通信***规定的，或者网络设备配置的，或者可以是网络设备和终端设备共同确定的，本申请实施例并不限定。
在一些可能的实现方式中，所述网络设备在所述第一周期内在所述第一时频资源前发送所述第一SSB的次数小于N1。

因此，网络设备在该M1个时频资源上进行该第一SSB的N1次传输后，在该M1个时频资源中的其他候选时频资源上可以不再传输该第一SSB，因此，网络设备通过在第一周期内配置多个时频资 源增加SSB的发送机会的同时，还能够降低SSB的发送次数，从而能够降低SSB发送的资源开销。
可选地，在该第二时频资源后的其他候选时频资源上，网络设备可以进行数据的传输，从而能够提升资源利用率。
在一些可能的实现方式中，所述第一时频资源为K1个时频资源中的一个时频资源，所述K1个时频资源为所述M1个时频资源中用于发送所述第一SSB的时频资源，K1为正整数，1≤K1≤N1。
在一些可能的实现方式中，所述K1个时频资源为所述M1个时频资源中所述网络设备获得信道使用权的前K1个时频资源。

因此，终端设备可以根据所述第一指示信息，即可确定该第一周期内的该第一SSB的信息，进而可以根据该第一SSB的信息，在特定资源位置上进行该第一SSB的接收，或者在成功接收N1次后，在其他时频资源上不再进行该第一SSB的接收，能够降低终端设备的盲检复杂度。或者，终端设备可以根据所述第一指示信息确定该第一SSB的时频资源位置，并在进行数据接收时对该第一SSB进行速率匹配。
在一些可能的实现方式中，所述第一周期是根据以下中的至少一项确定的：
所述网络设备服务的终端设备个数、所述网络设备服务的小区的覆盖范围大小、所述终端设备接入所述网络设备的时延要求。
可选地，在另一些实施例中，该周期可以是根据SSB的发送周期确定的，例如，该周期可以为80ms，160ms等。

所述网络设备从M2个时频资源中确定获得信道使用权的第六时频资源，所述M2个时频资源是所述网络设备为所述第一载波上的所述第一周期配置的用于传输所述第二SSB的时频资源，M2为正整数，M2≥2；
所述网络设备通过所述第六时频资源向所述终端设备发送所述第二SSB。
在一些可能的实现方式中，所述第六时频资源为K2个时频资源中的一个时频资源，所述K2个时频资源为所述M2个时频资源中用于发送所述第二SSB的时频资源，K2为正整数，1≤K2≤N2，其中，N2为所述网络设备在所述第一周期内发送所述第二SSB的最大次数，N2为正整数，1≤N2＜M2。
在一些可能的实现方式中，所述K2个时频资源为所述M2个时频资源中所述网络设备获得信道使用权的前K2个时频资源。
在一些可能的实现方式中，所述网络设备向所述终端设备发送第二指示信息，所述第二指示信息用于指示所述网络设备在所述第一周期内发送所述SSB组的信息。
在一些可能的实现方式中，所述第二指示信息用于指示以下中的至少一项：

因此，终端设备可以根据所述第二指示信息，即可确定该第一周期内的该SSB组中的至少一个SSB的信息，进而可以根据该SSB组的信息，在特定位置上进行该SSB组中的至少一个SSB的接收，或者在该SSB组中的某个SSB成功接收达到最大次数(例如第一SSB接收N1次，第二SSB接收N2次)后，在其他时频资源上不再接收该SSB组中的该个SSB，能够降低终端设备的盲检复杂度。或者，终端设备可以根据所述第二指示信息确定该SSB组的时频资源位置，并在进行数据接收时对该SSB组中的至少一个SSB进行速率匹配。

下面结合图1至图3对本申请实施例的信号传输的方法进行说明，应理解，图1至图3是本申请实施例的信号传输的方法的示意性流程图，示出了该方法的详细的通信步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其它操作或者图1至图3中的各种操作的变形。
此外，图1至图3中的各个步骤可以分别按照与图1至图3所呈现的不同的顺序来执行，并且有可能并非要执行图1至图3中的全部操作。
图1是根据本申请实施例的信号传输的方法的示意性流程图，如图1所示，该方法100包括：
S110，网络设备对第一载波进行检测，并根据检测结果从M1个时频资源中确定获得信道使用权的第一时频资源，所述M1个时频资源是所述网络设备为所述第一载波上的第一周期配置的可用于传输第一同步信号块SSB的时频资源，M1为正整数，M1≥2；
S120，所述网络设备通过所述第一时频资源向终端设备发送所述第一SSB。
具体而言，网络设备可以为第一载波上的第一周期配置M1个时频资源，该M1个时频资源为该网络设备在该第一载波上的第一周期内能够用于传输第一SSB的时频资源，即该M1个时频资源可用于传输该第一SSB，或者，该M1个时频资源可以认为是能够用于传输该第一SSB的候选时频资源，但是，在实际传输中，该M1个时频资源是否都用于传输该第一SSB，本申请实施例对此不作限定，即该M1个时频资源可以包括实际用于传输第一SSB的时频资源和未用于传输第一SSB的时频资源。
例如，该M1个时频资源包括时频资源1、时频资源2和时频资源3，则该时频资源1、时频资源2和时频资源3为可用于传输该第一SSB的时频资源，在实际传输中，若只在时频资源1上传输了该第一SSB，则该时频资源1为实际用于传输该第一SSB的时频资源，该时频资源2和该时频资源3为未用于传输该第一SSB的时频资源。
可选地，在本申请实施例中，该M1个时频资源中至少有一个时频资源不用于传输该第一SSB。
在本申请实施例中，网络设备可以对该第一载波进行信道检测，根据信道检测结果确定该M1个时频资源中的哪些时频资源可用，即哪些时频资源获得了信道使用权。例如，若在该M1个时频资源中的时频资源K上的信道检测结果为信道空闲，则可以确定该时频资源K可用，即获得该时频资源K的信道使用权，否则，可以确定该时频资源K不可用，即未获得该时频资源K的信道使用权。其中，获得信道使用权的时频资源中可以包括第一时频资源，进一步地，该网络设备可以通过该第一时频资源向终端设备发送该第一SSB。
因此，在本申请实施例中，网络设备可以在第一周期内配置可用于传输该第一SSB的多个时频资源，有利于增加SSB的发送机会，并且该网络设备可以对第一载波进行信道检测，根据信道检测结果确定在该第一周期内的M1个时频资源中可用的第一时频资源，进一步地可以通过该第一时频资源发送该第一SSB，而不是在该M1个时频资源中的每个时频资源或特定时频资源上发送第一SSB，能够实现该第一SSB的有效传输，并且有利于提升资源利用效率。
可选地，在本申请实施例中，该第一时频资源可以包括一个时频资源，或者也可以包括多个时频资源。
可选地，在本申请实施例中，该第一载波可以为免授权载波，或者也可以为授权载波，本申请实 施例对此不作限定。
需要说明的是，若网络设备在该第一时频资源之前已经拿到信道使用权了(例如，网络设备在第一时频资源前已经开始进行数据传输了)，此情况下，该网络设备对该第一载波进行信道检测可以是在进行数据传输之前的时间资源上，相应地，该网络设备可以认为已经获得该第一时频资源的信道使用权而不必再进行信道检测；或者，网络设备可以在该第一时频资源之前进行信道检测，以确定该第一时频资源是否可用，从而在可用的情况下进行第一SSB的发送。应理解，本申请实施例并不特别限定网络设备对第一载波进行信道检测的具***置，只要能够根据信道检测结果确定M1个时频资源是否可用即可。
可选地，在本申请实施例中，若在该M1个时频资源上都信道检测失败，即未获得该M1个时频资源中的任一时频资源的信道使用权，则该网络设备可以不在该第一周期内进行第一SSB的发送，进一步的，该网络设备可以在该第一周期之后的第二周期内对该第一载波进行信道检测，并根据该第二周期内的信道检测结果进行该第一SSB的发送，具体实现过程参考第一周期内的实现过程，这里不再赘述。
应理解，网络设备在第一周期或第二周期内发送该第一SSB的次数可以和该周期内网络设备获得的信道使用权情况有关，例如，网络设备可以在第一周期内没有发送该第一SSB，在第二周期内发送一次该第一SSB。
可选地，网络设备配置SSB的候选时频资源时是按周期配置的，即，每个周期内SSB的候选时频资源配置相同。其中，第一周期是该配置周期中的一个周期，第二周期是该配置周期中的另一个周期，第一周期和第二周期的长度相同，第二周期位于第一周期之后。例如网络设备配置SSB的候选时频资源的周期为80ms，假设第一周期对应1～80ms，那么第二周期可以对应81～160ms。
可选地，该候选时频资源配置周期的长度可以为40ms，80ms，或160ms等中的一种。
可选地，在本申请实施例中，候选时频资源配置周期的长度(即所述第一周期的长度)可以是通信***规定的，或者也可以是网络设备配置的，或者可以是网络设备和终端设备共同确定的，本申请实施例并不限定该第一周期的长度的确定方式。
可选地，在一些实施例中，所述第一周期的长度可以是根据以下中的至少一项确定的：
所述网络设备服务的终端设备个数、所述网络设备服务的小区的覆盖范围大小、所述终端设备接入所述网络设备的时延要求。
例如，在网络设备服务的终端设备的个数较多时，可以配置较短的第一周期，从而终端设备想要进行初始接入或发起随机接入时，可以及时获取该SSB，有利于缩短终端设备接入网络的时延，提升用户体验；或者，在网络设备服务的小区的覆盖范围较大时，可以配置较短的第一周期，小区的覆盖范围较大在某种程度上也可以认为该网络设备服务的终端设备的个数较多，因此，配置较短的第一周期有利于终端设备在想要接入网络时，能够及时获取SSB，进行快速的初始接入；或者，在终端设备的接入时延要求较高时，需要网络设备发送SSB的频率更高，因此，配置较短的第一周期有利于终端设备在想要发起初始接入时，能够及时获取SSB，进行快速的接入。
再如，该第一周期也可以是根据所述网络设备服务的终端设备个数、所述网络设备服务的小区的覆盖范围大小、所述终端设备接入所述网络设备的时延要求中的至少两项确定的，例如，在网络设备服务的小区的覆盖范围大于特定阈值，并且终端设备的接入网络的时域要求高于特定阈值时，配置较短的第一周期，或者，在网络设备服务的终端设备的个数小于特定阈值，并且网络设备服务的小区的范围小于特定阈值时，配置较长的第一周期等，本申请实施例对此不作限定。
可选地，在一些实施例中，所述网络设备在所述第一周期内发送所述第一SSB的最大次数为N1，N1为正整数，1≤N1＜M1。
可选地，网络设备或通信***根据所述第一周期的长度、所述网络设备服务的终端设备个数、所述网络设备服务的小区的覆盖范围大小和所述终端设备接入所述网络设备的时延要求中的至少一项来确定所述第一周期内所述第一SSB的最大发送次数。
因此，在本申请实施例中，网络设备可以只在M1个时频资源中的部分时频资源上发送该第一SSB，而不是在该M1个时频资源中的每个时频资源上都发送第一SSB，能够降低SSB的发送次数，从而能够降低发送SSB的资源开销。
可选地，该N1的取值可以是由通信***规定的，或者网络设备配置的，或者可以是网络设备和终端设备共同确定的，本申请实施例并不限定。
可选地，在一些实施例中，所述网络设备在所述第一周期内在所述第一时频资源前发送所述第一SSB的次数小于N1。
即，该第一时频资源可以是该第一SSB的N1次传输中的一次传输所使用的时频资源，例如，该 第一时频资源可以是用于该第一SSB的第一次传输的，或者也可以是用于该第一SSB的第N1次传输的，或者也可以是用于该N1次传输中的中间的一次传输的，本申请实施例对此不作限定。
可选地，在一些实施例中，所述方法100还包括：
所述网络设备在所述M1个时频资源中晚于第二时频资源的时频资源上不发送所述第一SSB，其中，所述第二时频资源为所述M1个时频资源中所述网络设备第N1次发送所述第一SSB的时频资源。
具体来说，网络设备可以使用该M1个时频资源中的N1个获得信道使用权的时频资源进行该第一SSB的N1次传输，其中，该第二时频资源为该N1次传输中用于第N1次传输的时频资源，则在该M1个时频资源中该第二时频资源之后的其他时频资源上，该网络设备不再发送该第一SSB，即网络设备在该M1个时频资源上进行该第一SSB的N1次传输后，不再在该M1个时频资源中的其他候选时频资源上传输该第一SSB，因此，根据本申请实施例的信号传输方法，在增加SSB的发送机会，实现SSB的有效传输的情况下，还能够降低SSB的发送次数，从而能够降低发送SSB的资源开销。
可选地，在一些实施例中，在该第二时频资源后的其他候选时频资源上，网络设备可以进行数据的传输，从而能够提升资源利用率。
可选地，若该第一时频资源为用于该第一SSB的第N1次传输的时频资源，则该第一时频资源和该第二时频资源相同。
可选地，在一些实施例中，所述第一时频资源为K1个时频资源中的一个时频资源，所述K1个时频资源为所述M1个时频资源中用于发送所述第一SSB的时频资源，K1为正整数，1≤K1≤N1。
应理解，这里的该K1个时频资源是实际用于传输该第一SSB的时频资源，或者说，在该K1个时频资源上进行了该第一SSB的传输，即网络设备在该K1个时频资源上进行该第一SSB的K1次传输，其中，该第一时频资源可以为该K1个时频资源中的一个时频资源，可选地，该第一时频资源可以为该K1次传输中的任一次传输所使用的时频资源，本申请实施例对于该第一时频资源在该K1个时频资源中的位置不作具体限定。
可选地，在一些实施例中，所述K1个时频资源为所述M1个时频资源中所述网络设备获得信道使用权的前K1个时频资源。
例如，若该网络设备在M1个时频资源中的P个时频资源上获得信道使用权，其中，P≥K1，则该K1个时频资源可以为该P个时频资源中的前K1个时频资源，该K1个时频资源分别对应该第一SSB的K1次传输。
可选地，在一些实施例中，所述第一周期包括M1个子周期，所述M1个子周期中的每个子周期内包括所述M1个时频资源中的一个时频资源，即所述M1个子周期与所述M1个时频资源一一对应。
也就是说，在M1个子周期内的每个子周期内都可以配置一个能够用于传输该第一SSB的候选时频资源，可选地，每个子周期内的能够用于传输该第一SSB的候选时频资源的位置相同。
例如，该第一周期包括第一子周期和第二子周期，该M1个时频资源包括第三时频资源和第四时频资源，其中，该第三时频资源为该第一子周期内的候选时频资源，该第四时频资源为该第二子周期内的候选时频资源，则该第三时频资源在第一子周期内的位置与该第四时频资源在该第二子周期内的位置相同。
应理解，实际用于传输该第一SSB的该K1个时频资源可以分别对应K1个子周期，该K1个子周期在该M1个子周期中可以是连续的，或者也可以是不连续的，本申请实施例对此不作限定。
可选地，在一些实施例中，所述网络设备还可以向所述终端设备发送第一指示信息，所述第一指示信息用于指示所述网络设备在所述第一周期内发送所述第一SSB的信息。
可选地，所述第一指示信息用于指示以下中的至少一项：所述第一周期内所述第一SSB的最大发送次数信息、所述第一SSB的标识、所述第一SSB的波束标识。
可选地，一个波束的波束指示信息可以包括：与该波束之间满足准同址(Quasi-Co-Located，QCL)关系的参考信号的信号索引或波束标识。
可选地，本申请实施例中，接收一个信号所使用的波束，可以理解为，接收一个信号所使用的空间域接收滤波器(Spatial domain reception filter)；发送一个信号所使用的波束，可以理解为，发送一个信号所使用的空间域传输滤波器(Spatial domain transmission filter)。对于采用相同的空间域发送滤波器发送的两个信号，可以认为这两个信号相对于空间接收参数是QCL的。
作为示例而非限定，该第一指示信息可以用于指示该网络设备在该第一周期内待发送的该第一SSB的标识、次数、资源位置、发送该第一SSB所使用的波束标识等信息。
从而，终端设备可以根据所述第一指示信息确定该第一SSB的资源位置，发送次数等信息，进而可以在特定资源位置上接收该第一SSB，或者只接收特定次数的该第一SSB等，有利于降低终端设备盲检的复杂度。
可选地，在一具体的实施例中，所述网络设备可以在所述第一周期内的第五时频资源上发送所述第一指示信息。
此情况下，所述第一指示信息用于指示以下中的至少一项：所述第一周期内早于所述第五时频资源的时频资源上所述第一SSB的已发送次数信息、所述第一周期内晚于所述第五时频资源的时频资源上所述第一SSB的待发送次数信息、所述第一周期内晚于所述第五时频资源的时频资源上所述第一SSB的候选位置信息。
因此，终端设备可以根据所述第一指示信息，即可确定该第一周期内的该第一SSB的信息，进而可以根据该第一SSB的信息，进行该第一SSB的接收，例如，可以在特定资源位置上接收该第一SSB，或者在成功接收N1次后，在其他时频资源上不再继续接收该第一SSB等，能够降低终端设备的盲检复杂度。或者，终端设备可以根据所述第一指示信息确定该第一SSB的时频资源位置，并在进行数据接收时对该第一SSB进行速率匹配。
可选地，本申请实施例中的根据SSB的时频资源位置进行速率匹配，可以指：当终端设备被调度用于数据传输的时频资源中包括SSB的候选时频资源时，终端设备需要根据实际发送的SSB来进行速率匹配。作为示例而非限定，第一指示信息指示一个候选时频资源用于发送第一SSB，终端设备在进行数据接收时可以假设该个时频资源未用于数据传输，或者，第一指示信息指示一个候选时频资源未用于发送第一SSB，终端设备在进行数据接收时可以假设该个时频资源用于数据传输。
应理解，本申请实施例的时频资源可以包括时域资源和/或频域资源，其中，早于该第五时频资源的时频资源可以为在时域维度上早于该第五时频资源的时频资源，晚于该第五时频资源的时频资源可以为在时域维度上晚于该第五时频资源的时频资源，对于频域位置不作具体限定。
可选地，在一些实施例中，所述第一SSB为SSB组中的一个SSB，所述SSB组还包括第二SSB，所述方法100还可以包括：
所述网络设备从M2个时频资源中确定获得信道使用权的第六时频资源，所述M2个时频资源是所述网络设备为所述第一载波上的所述第一周期配置的用于传输所述第二SSB的时频资源，M2为正整数，M2≥2；
所述网络设备通过所述第六时频资源向所述终端设备发送所述第二SSB。

作为示例而非限定，SSB组包括S个SSB，网络设备在第一周期内配置M组时频资源，该M组时频资源中的每组时频资源包括S个时频资源，该S个时频资源分别用于发送该S个SSB，网络设备 配置该SSB组的最大发送次数为N，即该SSB组中的每个SSB的最大发送次数均为N。其中，该第一周期包括M个子周期，该M组时频资源与该M个子周期对应，该M组时频资源中的每组时频资源在该M个子周期中对应的子周期内的位置相同。
可选地，在一些实施例中，所述网络设备向所述终端设备发送第二指示信息，所述第二指示信息用于指示所述网络设备在所述第一周期内发送所述SSB组的信息。
可选地，在一些实施例中，所述第二指示信息用于指示以下中的至少一项：

可选地，在一具体的实施例中，所述网络设备在所述第一周期内的第七时频资源上发送所述第二指示信息，所述第二指示信息用于指示以下中的至少一项：
所述第一周期内早于所述第七时频资源的时频资源上所述SSB组中至少一个SSB的已发送次数信息、所述第一周期内晚于所述第七时频资源的时频资源上所述SSB组中至少一个SSB的待发送次数信息、所述第一周期内晚于所述第七时频资源的时频资源上所述SSB组中至少一个SSB的候选位置信息。
从而，终端设备可以根据所述第二指示信息，即可确定该第一周期内的该SSB组中的至少一个SSB的信息，进而可以根据该SSB组的信息，在特定位置上进行该SSB组中的至少一个SSB的接收，或者在该SSB组中的某个SSB成功接收达到最大次数(例如第一SSB接收N1次，第二SSB接收N2次)后，在其他时频资源上不再接收该SSB组中的该个SSB，能够降低终端设备的盲检复杂度。或者，终端设备可以根据所述第二指示信息确定该SSB组的时频资源位置，并在进行数据接收时对该SSB组中的至少一个SSB进行速率匹配。
应理解，早于该第七时频资源的时频资源可以为在时域维度上早于该第七时频资源的时频资源，晚于该第七时频资源的时频资源可以为在时域维度上晚于该第七时频资源的时频资源，对于频域维度上的大小不作具体限定。
以下，结合图2所示的具体示例，说明根据本申请实施例的信号传输的方法。
在图2所示的示例中，SSB组可以包括SSB1、SSB2、SSB3、SSB4和SSB5，每个SSB的最大传输次数为1次，当然，每个SSB的最大传输次数也可以大于一次，或者每个SSB对应的最大传输次数也可以不同，SSB组包括的SSB的数量也可以为其他数量，在其他情况下，也可以采用类似的方式进行信号传输，不作赘述。
在该图2中，每个子周期内都配置有可用于传输该SSB组中的每个SSB的时频资源(即候选时频资源)，该网络设备可以对第一载波进行信道检测，以确定在该第一周期内的第一子周期内(即该第一周期内的第一个子周期)的每个候选时频资源是否可用。
在该第一子周期内，若可用于传输该SSB1和该SSB2的时频资源不可用，可用于传输该SSB3～SSB5的时频资源可用，则在该第一子周期内，该网络设备可以在可用于传输该SSB3～SSB5的时频资源上分别传输该SSB3～SSB5，在该第一子周期内不进行SSB1和SSB2的传输，由于SSB3～SSB5已达到最大传输次数，因此，在该第一子周期后的第二子周期内，该网络设备可以不进行SSB3～SSB5的传输。
该网络设备可以对第一载波进行信道检测，根据信道检测结果确定在该第二子周期内可用于传输SSB1和SSB2的时频资源是否可用，若可用于传输SSB1和SSB2的时频资源都可用，则在该第二子周期内，该网络设备可以在可用于传输SSB1和SSB2的时频资源分别进行SSB1和SSB2的传输，或者若在该第二子周期内，该可用于传输该SSB1和SSB2的时频资源不可用，进一步的，该网络设备可以对第一载波进行信道检测，根据信道检测结果确定在第三子周期内是否可以进行该SSB1和SSB2的发送。
对于终端设备而言，若该终端设备处于初始接入状态，由于终端设备不知道网络设备的配置，即该终端设备不知道网络设备配置的该M1个时频资源的位置，并且不知道该SSB组中的每个SSB的发送次数，因此，终端设备会盲检所有可能的SSB，直到接入网络。
或者，若终端设备处于连接态，终端设备可以获知该M1个时频资源的信息，前述的第一指示信息或第二指示信息等信息，因此，终端设备可以在该第一周期内的该M1个时频资源上检测SSB，假设SSB的最大传输次数为1，若终端设备检测到一次SSB，则可以不在其他时频资源上继续检测SSB。
例如，若在第一子周期内，该终端设备在该SSB1对应的时频资源上未检测到SSB1，该终端设 备可以在第二子周期内的该SSB1对应的时频资源上继续检测SSB1，若检测到该SSB1，则不在该第二子周期后的其他子周期内继续检测SSB1。
或者，若终端设备处于连接态，终端设备可以获知该M1个时频资源的信息，前述的第一指示信息或第二指示信息等信息，因此，终端设备可以根据该第一指示信息或第二指示信息对SSB进行速率匹配。
例如，该终端设备被调度用于数据传输的资源中包括第二子周期内的SSB1～SSB5的候选时频资源，终端设备根据第二指示信息可以确定SSB1和SSB2的两个候选时频资源分别用于发送SSB1和SSB2，SSB3～SSB5的三个候选时频资源未用于发送SSB，因此，该终端设备可以假设SSB3～SSB5的三个候选时频资源用于数据传输。
因此，根据本申请实施例的信号传输的方法，网络设备可以在一个周期内对一组SSB中的每个SSB配置多个候选时频资源，能够增加SSB的发送机会，实际传输时，若网络设备在该周期内的一个候选时频资源上成功传输对应的SSB，则可以不在其他候选时频资源上继续传输该SSB，因此，在增加SSB的发送机会的同时，还有利于降低发送SSB的资源开销。
并且，连接态的终端设备若在该周期内的一个候选时频资源上检测到SSB，则可以停止对该周期内的其他候选时频资源上的SSB的盲检测，有利于降低终端设备的盲检复杂度。
