具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
应理解，本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解，申请实施例中的“第一”、“第二”以及“第三”仅为了区分，不应对本申请构成任何限定。
还应理解，在本申请的各种实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
还应理解，在本申请的各种实施例中，各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
本申请实施例可以应用于各种使用FHSS的通信系统。例如，非授权频谱机器通信(enhanced machine type communication on unlicensed spectrum，eMTC-U)系统或蓝牙系统。
本申请实施例中，网络设备是一种部署在无线接入网中用以为终端设备提供无线通信功能的装置。网络设备可以包括各种形式的基站，宏基站，微基站(也称为小站)，中继 站，接入点，新无线控制器(new radio controller，NR controller)，集中式网元(centralized unit)，射频拉远模块，分布式网元(distributed unit)，接收点(transmission reception point，TRP)或传输点(transmission point，TP)，或者任何其它无线接入设备，但本申请实施例不限于此。其中，在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同。例如，网络设备可以是无线局域网(wireless local area networks，WLAN)中的接入点(access point，AP)，还可以是LTE系统中的演进的节点B(evolved NodeB，eNB或者eNodeB)。或者，网络设备还可以是第三代(3rd generation，3G)系统的节点B(Node B)，另外，该网络设备还可以是中继站或接入点，车载设备或者未来第五代通信(fifth-generation，5G)网络中的网络设备或者未来演进的公共陆地移动网络(public land mobile network，PLMN)网络中的网络设备等。
本申请实施例中，终端设备可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备。终端设备可以是通信系统(例如，5G)中通过网络设备(例如，NR或TRP)接入网络侧的设备，也可以称之为用户设备(user equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。该终端设备还可以是中继设备(Relay)。
图1是现有技术中两类通信设备传输数据发生碰撞的一例的示意性图。如图1所示，用于跳频传输的频域资源可能与宽带技术的频域资源有重合，在此情况下，通过FHSS传输的数据与通过宽带技术传输的数据可能会发生碰撞，从而导致传输失败。

图2为适用于本申请实施例的应用场景图。如图2所示，该应用场景包括网络设备101，该应用场景还包括位于网络设备101覆盖范围之内的多个终端设备102。网络设备101可以与终端设备102通过FHSS技术通信。应理解，图2中仅以网络设备101覆盖范围内的两个终端设备102作为示例。显然，网络设备101的覆盖范围内也可以有更多的终端设备102。
为了便于理解本申请实施例，首先对本申请实施例的几个概念进行说明。
跳频传输：跳频传输是指网络设备或终端设备在发送数据的时候载波的频率在一定频带范围内按照约定的图案或者序列进行跳变。例如，在每个信道上传输一段时间(例如，400毫秒)后进行跳频，每个信道传输的时间通过协议规定。
跳频图案：跳频图案代表了通信双方的信号载波频率(信道)的变化规律。例如，网络设备和终端设备根据该规律进行数据收发。换句话说，根据跳频图案可以得到某个时刻在哪个信道上进行数据传输。
以下，结合图3-图6对本申请实施例的用于传输数据的方法进行详细说明。
图3是根据本申请实施例的用于传输数据的方法的一例的示意性交互图。应理解，图3示出了方法200的详细的步骤或操作，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仅执行图3中部分操作。
该方法200可以由网络设备和/或终端设备执行。可选地，网络设备和终端设备可分别对应上述通信场景中的网络设备101和终端设备102。如图3所示，该方法200可以包 括210以及220。
210、网络设备广播第一信道信息；相应地，终端设备可以接收该第一信道信息。
应理解，网络设备广播第一信道信息可以是指：网络设备通过一个消息发送第一信道信息，使能多个终端设备获取该第一信道信息。具体地，网络设备可以通过多种方式中的一种广播该第一信道信息。
例如，网络设备可以发送携带第一信道信息的广播消息。可选地，该广播消息可以是系统消息，其中，该系统消息可以包括主系统信息块(master information block，MIB)消息，或系统信息块(system information block，SIB)消息。
又例如，网络设备可以通过小区级别的控制信道发送该第一信道信息。其中，该小区级别的控制信道可以为公共控制信道(common physical downlink control channel，CPDCCH)。
所述第一信道信息用于指示N(N≥1)个信道中每个信道的信道状态，所述信道状态为信道可用或者信道不可用。其中，该第一信道信息可以通过以下多种方式中的一种指示每个信道的信道状态。
1)第一信道信息具体用于指示N个信道中每个信道是否可用。
可选地，该第一信道信息可以为位图(bitmap)。该位图的每个比特位可以用于指示所述N个信道中的至少一个信道是否可用。也就是说，该位图中的每个比特位可以对应至少一个信道。应理解，每个比特位对应的信道的数量可以相同也可以不同。
例如，该位图可以包括与N个信道分别对应的N个比特位，每个比特位用于指示对应的一个信道是否可用。
又例如，该位图包括K(2≤K≤N)个比特位。该K个比特位中每个比特位对应J(J≥2)个信道，每个比特位用于指示对应的J个信道是否可用，可选地，J为预设值，该预设值可以是标准中定义的也可以是网络设备预先配置的。可选地，所述J个信道的带宽之和大于或等于预定阈值。该预定阈值可以是标准中定义的也可以是网络设备预先配置的。可选地，该J个信道在频域上是连续的。
再例如，该位图包括L(2≤L≤N)个比特位。该L个比特位中K(1≤K≤L)个比特位对应J个信道，(L-K)个比特位对应G(G≥1)个信道。其中，J的具体说明可以参见上文的相关描述，为了简洁不在此赘述。
也就是说，在本申请实施例中，位图中的比特位可以用于指示一个信道是否可用，和/或该位图中的比特位用于指示多个信道是否可用。进一步可选地，考虑到2.4GHz上的干扰主要来自宽带系统即wifi系统，可以基于wifi系统的信道带宽，确定上述J值。
图4是wifi系统的信道的示意性图。如图4所示，wifi系统包括13个信道。每个设备使用该13个信道中的一个信道进行数据传输。由图4可以看出，该13个信道中相邻两个信道的中心频点之间的间隔是5MHz。假设，wifi设备使用该13个信道中的第一个信道进行数据传输，该wifi设备占用的频段为2402-2422MHz。也就是说，该2402-2422MHz全部被wifi设备占用。假设该wifi设备使用该13个信道中第二信道进行数据传输，该wifi设备占用的频段为2407-2427MHz。也就是说，频段2402-2407MHz未被占用，频段2407-2427MHz被占用。由此可以看出，wifi设备占用或未占用的频段的最小粒度为5MHz。
基于图4，作为可选地一例，该J个信道的带宽之和可以等于或近似等于5MHz。假 设FHSS系统中每个信道的带宽为1.4MHz，5≤1.4*J，即，5/1.4≤J。可选地，3≤J。即，上述K个比特位中的每个比特位可以用于指示3个信道是否可用。
例如，假设FHSS系统共有75(N＝75)个信道，该位图可以包括25个比特位，每个比特位用于指示3个信道是否可用。
又例如，假设FHSS系统共有79(N＝79)信道，由于79非3的整数倍，该位图可以包括27个比特位，该27个比特位中前26个比特位中每个比特位用于指示3个信道是否可用，该27个比特位中最后一个比特位用于指示一个信道(第79个信道)是否可用。
基于图4，作为可选地另一例，该J个信道的带宽之和可以等于或近似等于20MHz。例如，1.4*J≤20MHz，即，J≤20/1.4。可选地，J≤15。即，上述K个比特位中的每个比特位可以用于指示15个信道是否可用。
例如，假设FHSS系统共有75(N＝75)个信道，该位图可以包括5个比特位，每个比特位用于指示15个信道是否可用。
又例如，假设FHSS系统共有79(N＝79)个信道，该位图可以包括6个比特位，该6个比特位中前5个比特位中每个比特位用于指示15个信道是否可用，该6个比特位中最后一个比特位用于指示四个信道(第76、77、78和79四个信道)是否可用。
也就是说，假设FHSS系统中每个信道的带宽为DMHz，可选地，该J可以满足以下公式：
5/D≤J≤20/D            (1)
其中，D为FHSS系统中每个信道的带宽的大小，J为信道的数量。可选地，若D＝1.4MHz，3≤J≤15。
在本申请实施例中，将多个信道绑定在一起通过一个比特位进行指示，有利于减少第一信道信息的开销。
2)第一信道信息具体用于指示N个信道中每个信道可用。
也就是说，该第一信道信息可以为白名单(white list)。该第一信道信息指示的信道均为可用信道。例如，每个信道具有索引(或标识)，该第一信道信息可以用于指示可用信道的索引。
例如，该第一信道信息可以包括该N个信道中每个信道的标识，
又例如，该N个信道在频域上是连续的，该第一信道信息包括索引信息和该索引信息对应的数量信息，该索引信息可以用于指示该N个信道中编号最小(或编号最大)的信道，该数量信息用于指示N，该索引信息和数量信息共同用于指示该N个信道为可用信道。
3)第一信道信息具体用于指示N个信道中每个信道不可用。
也就是说，该第一信道信息可以为黑名单(black list)。该第一信道信息指示的信道均为不可用信道。该第一信道信息用于指示N个信道中每个信道不可用的相关说明，可以参见上文的相关描述，为了简洁，不在此赘述。
220、所述网络设备根据所述每个信道的信道状态，确定用于跳频传输的信道；相应地，终端设备根据所述第一信道信息(所述每个信道的信道状态)，确定用于跳频传输的信道。
应理解，该用于跳频传输的信道包括多个信道。为了便于说明，可以将“用于跳频传输的信道”记为“信道集合”，将“根据所述N个信道中每个信道的信道状态，确定的用于 跳频传输的信道”记为“第一信道集合”
以网络设备为例，假设网络设备根据该每个信道的信道状态确定信道#1不可用，该网络设备可以确定信道#1不属于该第一信道集合，假设网络设备根据该每个信道的信道状态确定信道#2可用，该网络设备可以确定信道#2属于用于该第一信道集合。网络设备和终端可以根据约定的跳频规则在该第一信道集合中选择某个或者某些信道进行数据传输。在220中终端设备的相关说明可以参见网络设备的相关描述，为了简洁不在此赘述。
可选地，该方法200还可以包括：
230、所述网络设备根据所述确定的用于跳频传输的信道发送数据或接收数据；相应地，所述终端设备根据所述确定的用于跳频传输的信道接收数据或发送数据。
可选地，所述网络设备根据所述确定的用于跳频传输的信道发送数据或接收数据，可以包括：所述网络设备根据所述第一信道集合向终端设备发送数据，或所述网络设备根据所述第一信道集合从终端设备接收数据。同理，可选地，所述终端设备根据所述确定的用于跳频传输的信道接收数据或发送数据，可以包括：所述终端设备根据所述第一信道集合从所述网络设备接收数据，或所述终端设备根据所述第一信道集合向所述网络设备发送数据。应理解，所述终端设备还可以根据所述第一信道集合向其他终端设备发送数据或从其他终端设备接收数据。
作为可选地一例，所述网络设备根据所述确定的用于跳频传输的信道发送数据或接收数据，可以包括：网络设备根据所述第一信道集合确定跳频图案，网络设备根据所述跳频图案发送数据或接收数据。
为了便于说明，可以将230记为“所述网络设备和所述终端设备根据所述确定的用于跳频传输的信道进行数据传输”。
在本申请实施例中，网络设备可以发送第一信道信息，第一信道信息用于指示N个信道中每个信道的信道状态，以便于终端设备获取该N个信道的信道状态。网络设备(或终端设备)可以根据该N个信道的信道状态，确定用于跳频传输的信道，有利于避免网络设备(或终端设备)在不可用信道上发送数据或接收数据，有利于提高数据传输成功率。进一步地，与网络设备通过单播方式发送第一信道信息相比，网络设备广播第一信道信息，有利于节省信令开销。
进一步地，网络设备可以通过以下多种方式中的一种广播第一信道信息。
方式#1
该210可以包括：
网络设备在用于传输同步信号的信道上，广播所述第一信道信息。
具体地，FHSS系统中的信道包括数据信道和用于传输同步信号的信道。其中，数据信道是指FHSS系统中用于跳频传输的信道(信道集合)。应理解，网络设备在不同情况下确定的用于跳频传输的信道不同，但是，网络设备确定的用于跳频传输的信道均属于数据信道。
例如，假设FHSS系统包括79个数据信道，该79个数据信道包括信道#1和信道#2，在第一时刻，网络设备通过信道检测确定信道#1不可用且信道#2可用，网络设备确定用于跳频传输的信道不包括信道#1且包括信道#2，网络设备确定的用于跳频传输的信道属于该79个数据信道。在第二时刻，网络设备通过信道检测确定信道#1可用且信道#2不可 用，网络设备确定用于跳频传输的信道包括信道#1且不包括信道#2，网络设备确定的用于跳频传输的信道属于该79个数据信道。
通常情况下，为了提高同步信号的传输成功率，在FHSS系统中用于传输同步信道的信道具有固定的频率位置，且用于传输同步信号的频段位于wifi系统的保护带(guardband)内。应理解，在wifi系统中，网络设备和终端设备不会在保护带内传输数据，可以认为在wifi系统中，wifi的保护带为空白资源。也就是说，用于传输同步信号的信道不会受到wifi系统的干扰。
例如，目前，网络设备通过锚信道(Anchor信道)传输同步信号。应理解，该Anchor信道具有固定的频率位置，且Anchor信道的频段位于wifi系统的保护带内。
图5是FHSS系统中信道的一例的示意性图。如图5所示，FHSS系统包括数据信道和Anchor信道。网络设备通过Anchor信道传输同步信号，例如，网络设备通过Anchor信道传输主同步信号(primary synchronization signal，PSS)、辅同步信号(secondary synchronization signal，SSS)。网络设备还可以通过Anchor信道传输MIB、SIB等信息。
基于此，为了提高第一信道信息的传输成功率，网络设备可以在用于传输同步信号的信道上，广播第一信道信息，例如，网络设备可以在Anchor信道上广播第一信道信息，该方案有利于提高网络设备传输第一信道信息的成功率。进一步地，Anchor信道在固定的信道进行数据发送，不进行跳频，使得第一信道信息通过Anchor信道发送，有利于网络设备和终端设备对齐信道。也就是说，网络设备在Anchor信道上发送第一信道信息，终端设备在Anchor信道接收第一信道信息，能够避免网络设备在数据信道#1发送第一信道信息，终端设备在数据信道#2上接收第一信道信息的问题。
应理解，FHSS系统可以包括多个Anchor信道，网络设备可以在该多个Anchor信道上发送同步信号，也可以在该多个Anchor信道中的一个Anchor信道上发送同步信号，应理解，不论网络设备通过何种方式发送同步信号，网络设备可以在用于发送同步信号的信道上发送第一信道信息。例如，网络设备可以在多个Anchor信道中的至少两个Anchor信道上发送第一信道信息，网络设备也可以在多个Anchor信道的某个Anchor信道上发送第一信道信息，本申请实施例不在此限定。
方式#2
该210可以包括：
网络设备在数据信道上，广播第一信道信息。
在本申请实施例中，网络设备可以发送信道信息，以便于网络设备和终端设备可以更新用于跳频传输的信道。作为可选地一例，在网络设备广播第一信道信息之前，该方法200还可以包括：
201、网络设备广播第二信道信息；相应地，终端设备接收该第二信道信息。其中，该第二信道信息用于指示E(E≥1)个信道中每个信道的信道状态。
应理解，该201的相关说明可以参见210的相关描述，为了简洁不在此赘述。
可选地，该方法200还可以包括：
202、网络设备根据该E个信道中每个信道的信道状态确定用于跳频传输的信道；相应地，终端设备根据该E个信道中每个信道的信道状态确定用于跳频传输的信道。
可选地，该方法200还可以包括：
203、网络设备和终端设备根据该确定的用于跳频传输的信道进行数据传输。
也就是说，网络设备可以更新信道信息，以便于网络设备和终端设备可以根据更新后的信道信息，更新用于跳频传输的信道(信道集合)。在本申请实施例中，可以将该第二信道信息认为是“更新前的信道信息”，将该第一信道信息认为是“更新后的信道信息”。将该“根据该E个信道中每个信道的信道状态，确定的用于跳频传输的信道”认为是“更新前的用于跳频传输的信道”。将该“根据N个信道中每个信道的信道状态，确定的用于跳频传输的信道”认为是“更新后的用于跳频传输的信道”。由上文可知，该“更新后的用于跳频传输的信道”可以记为“第一信道集合”，同理，该“更新前的用于跳频传输的信道”可以记为“第二信道集合”。
即，在网络设备和终端设备使用第一信道集合进行数据传输之前，网络设备和终端设备使用第二信道集合进行数据传输。
应理解，网络设备和终端设备使用第二信道集合进行数据传输包括：网络设备和终端设备根据第二信道集合确定(或计算)跳频图案，网络设备和终端设备根据该跳频图案进行数据传输。为了便于说明，可以将“根据第二信道集合确定的跳频图案”记为“第二跳频图案”。同理，可以将“根据第一信道确定的跳频图案”记为第一跳频图案。也就是说，可以认为更新信道信息用于更新用于跳频传输的信道集合。还可以认为更新信道信息用于更新跳频图案。
通常情况下，网络设备进行信道信息更新，是因为当前的信道集合(用于跳频传输的信道)可能存在不可用的信道，或原本不可用的信道现在可用。例如，当前用于跳频传输的信道包括信道#1，网络设备通过信道检测，确定信道#1不可用，网络设备需要更新信道信息，以用于使得终端设备获知该信道#1不可用。终端设备接收到该更新的信道信息之后，可以根据该更新后的信道信息确定的用于跳频传输的信道不包括该信道#1，从而有利于提高数据传输的效率。
由于第二信道集合可能存在不可用的信道，网络设备根据第二跳频图案发送第一信道信息可能会导致第一信道信息传输失败。例如，第二信道集合包括信道#1，网络设备通过信道检测确定该信道#1不可用，在此情况下，若网络设备根据第二跳频图案，在信道#1上传输第一信道信息，会导致第一信道信息发送失败。
基于此，网络设备可以根据该N个信道的信道状态，确定用于发送第一信道信息的信道(数据信道)。也就说，网络设备可以不根据第二跳频图案进行数据传输。在此情况下，该方法200还可以包括：
204、网络设备在用于传输同步信号的信道上发送信道指示信息，相应地，终端设备接收该信道指示信息。其中，所述信道指示信息用于通知用于广播第一信道信息的信道。
可选地，假设用于传输同步信号的信道为Anchor信道，所以信道指示信息在Anchor信道发送，可以方便的让网络设备和终端设备对齐跳频的信道。也就是说，网络设备在Anchor信道上发送信道指示信息，终端设备在Anchor信道接收信道指示信息，能够避免网络设备在数据信道#1发送信道指示信息，终端设备在数据信道#2上接收信道指示信息的问题，从而有利于提高终端设备接收信道指示信息的成功率，有利于网络设备发送第一信道信息的信道和终端设备接收第一信道信息的信道对齐。
终端设备接收到该信道指示信息，可以根据该信道指示信息确定第一信道信息的位 置，以便于终端设备可以在该位置上接收该第一信道信息。
例如，该信道指示信息用于指示信道#2，终端设备在Anchor信道上接收该信道指示信息之后，可以跳频至信道#2接收该第一信道信息。
进一步可选地，该信道指示信息还可以用于指示用于广播第一信道信息的时域资源。例如，该信道指示信息用于指示信道#2子帧#2，终端设备在Anchor信道上接收该信道指示信息之后，可以在信道#2子帧#2的位置处接收该第一信道信息。
在本申请实施例中，网络设备在用于传输同步信号的信道上广播第一信道信息，或网络设备在用于传输同步信号的信道上发送与第一信道信息相关的信息(信道指示信息)，一方面，有利于提高终端设备接收第一信道信息的成功率；另一方面，终端设备在进行小区搜索或随机接入的时候，可以在用于传输同步信号的信道上获取该第一信道信息或信道指示信息，该方法有利于未与网络设备连接的终端设备获取该第一信道信息。该方案具有较好的兼容性以及适用性。
进一步地，该方法200还可以包括：
205、网络设备发送更新指示信息；相应地，终端设备接收该更新指示信息。其中，更新指示信息用于通知信道信息更新。
该终端设备对用于传输同步信号的信道监听方式可以包括：
1)实时监听
即，终端设备实时监听用于传输同步信号的信道。该方式有利于避免终端设备漏接收网络设备发送的信息，但是该方式的功耗较大。
2)周期性监听
即，终端设备周期性地监听用于传输同步信号的信道。相较于实时监听，该方式可以降低终端设备的功耗，但是该方案不利于终端设备及时获取网络设备发送的信息。
基于此，在本申请实施例中，网络设备可以发送更新指示信息，终端设备接收到该更新指示信息之后，可以获知信道信息更新，以便于终端设备确定需要获取该第一信道信息。
可选地，终端设备接收到该更新指示信息之后，可以监听用于传输同步信号的信道，以用于终端设备在该用于传输同步信号的信道上获取该第一信道信息，或以用于终端设备在用于传输同步信号的信道上获取信道指示信息，并根据信道指示信息获取该第一信道信息。
该方案不但有利于降低终端设备的功耗，还有利于终端设备及时获取相应信息，有利于终端设备获取该第一信道信息。
应理解，终端设备接收更新指示信息监听用于传输同步信号的信道是本申请实施例优选的实现方式，不应对本申请构成任何限定。若终端设备不发送信道指示信息，直接在数据信道上广播第一信道信息，终端设备接收到更新指示信息之后在数据信道上监听广播消息，以用于获取该第一信道信息。
其中，网络设备可以通过多种方式中的一种发送该更新指示信息。
作为可选地一例，网络设备可以通过单播消息发送该更新指示信息。例如，假设终端设备#1当前接入网络设备#1，网络设备#1将要更新信道信息，该网络设备#1可以通过单播消息向终端设备#1发送更新指示信息，以便于终端设备#1根据更新指示信息去监听用于传输同步信号的信道。其中，该单播消息可以包括物理层消息或无线资源控制(Radio  Resource Control，RRC)消息。
作为可选地另一例，网络设备可以通过寻呼消息发送该更新指示信息。例如，假设终端设备#2当前未接入网络设备#1，网络设备#1将要更新信道信息，该网络设备#1可以通过寻呼消息向终端设备#2发送更新指示信息，以便于终端设备#2根据更新指示信息去监听用于传输同步信号的信道。
作为可选地再一例，网络设备可以通过广播消息发送该更新指示信息。为了便于区分，可以将携带第一信道信息的广播消息记为“第一广播消息”，将携带更新指示信息的广播消息记为“第二广播消息”。网络设备可以通过第二广播消息发送更新指示信息，该更新指示信息具体为与第三广播消息的MIB值标签(valuetage)不相等的MIB值标签，或该更新指示信息具体为与第三广播消息的SIB值标签不相等的SIB值标签，所述第三广播消息为所述第二广播消息的上一个广播消息。也就是说，网络设备可以通过更新MIB值标签或更新SIB值标签向终端设备指示信道信息更新，相应地，终端设备可以根据MIB值或SIB值标签是否发生变化，确定信道信息是否更新。
进一步地可选地，该205可以包括：
所述网络设备在第一时段内发送所述更新指示信息。
可选地，该210可以包括：
所述网络设备在第二时段内广播第一信道信息；相应地，终端设备在第二时段内接收第一信道信息。
也就是说，网络设备在第一时段内发送更新指示信息，网络设备可以从第二时段开始广播第一信道信息。应理解，网络设备在第一时段仍然发送第二信道信息。即，网络设备在第一时段仍然发送更新前的信道信息。
可选地，该230可以包括：
所述网络设备从第二时段的起始位置开始使用所述第一信道集合与终端设备进行数据传输；与之对应，终端设备可以从第二时段的起始位置开始通过监听用于传输同步信号的信道，获取第一信道信息，或获取信道指示信息并根据信道指示信息获取第一信道信息。
图6是根据本申请实施例的用于传输数据的方法的一例的示意性图。如图6所示，该网络设备可以在第一时段内发送更新指示信息，该网络设备在第二时段广播第一信道信息，网络设备在第二时段的起始位置开始使用第一信道集合发送数据或接收数据。与之对应的，终端设备可以在第一时段内接收更新指示信息，该终端设备根据该更新指示信息在第二时段监听用于传输同步信号的信道，以用于接收该第一信道信息，该终端设备可以根据该第一信道信息确定第一信道集合，终端设备可以根据该第一信道集合接收数据或发送数据。可选地，网络设备在第一时段广播第二信道信息。
在本申请实施例中，网络设备和终端设备在第一时段可以继续使用第二信道集合进行数据传输。对于网络设备而言，网络设备在第二时段开始根据第一信道集合进行数据传输，对于终端设备而言，终端设备在接收到第一信道信息之后开始根据第一信道集合进行数据传输。
作为可选地一例，如图5所示，网络设备在第一时段内广播第二信道信息。以便于网络设备和终端设备根据第二信道集合进行数据传输。网络设备在第一时段内发送更新指示信息，以便于网络设备和终端设备在第二时段进行信道集合更新。
也就是说，网络设备在一个时段内广播的信道信息不发生变化。例如，网络设备在第一时段广播第二信道信息，网络设备在第一时段确定更新信道信息，网络设备在第一时段继续广播第二信道信息。网络设备在第二时段内广播第一信道信息。
具体地，若网络设备发送更新指示信息之后，立马广播第一信道信息，在此情况下，可能有些终端设备未接收到该更新指示信息，导致该终端设备未能及时进行信道集合更新，导致该终端设备后续传输数据失败。网络设备在一个时段广播更新指示信息，在下一个时段更新信道信息，有利于网络设备和终端设备同步更新信道集合，有利于提高传输数据成功率。
图7是根据本申请实施例的用于传输数据的方法的另一例的示意性图。如图7所示，该网络设备可以在第一时段内发送更新指示信息，该网络设备在第二时段发送信道指示信息，网络设备在信道指示信息指示的位置处广播第一信道信息，网络设备在第二时段的起始位置开始使用第一信道集合发送数据或接收数据。与之对应的，终端设备可以在第一时段内接收更新指示信息，该终端设备根据该更新指示信息在第二时段监听用于传输同步信号的信道，以用于接收该信道指示信息，该终端设备可以根据该信道指示信息接收第一信道信息，并根据该第一信道信息确定第一信道集合，终端设备根据该第一信道集合接收数据或发送数据。
与上文中描述的类似，网络设备在第一时段可以广播该第二信道信息。为了便于说明，可以将“用于通知用于广播第一信道信息的信道的信道指示信息”记为“第一信道指示信息，将“用于通知用于广播第二信道信息的信道的信道指示信息”记为“第二信道指示信息”。网络设备可以在第一时段内发送第二信道指示信息，以便于终端设备在第一时段内可以根据该第二信道指示信息，接收第二信道信息。该方案的具体说明可以参见上文的相关描述，为了简洁不在此赘述。
进一步地可选地，在第二时段内网络设备可以周期地广播该第一信道信息。同理，网络设备可以在第一时段内周期性地广播该第二信道信息。
也就是说，在本申请实施例中，网络设备可以周期性地广播信道信息，并且在一个时段内网络设备广播的信道信息不变。例如，网络设备在第一时段周期性地广播第二信道信息，即使网络设备在第一时段发送更新指示信息，网络设备仍然在第一时段广播第二信道信息。同理，网络设备从第二时段开始周期性地广播第一信道信息，直到信道信息再次更新。
例如，网络设备在第一时段之前周期性地广播第二信道信息，假设网络设备在第一时段内发送更新指示信息，网络设备在第一时段继续周期性地广播第二信道信息，网络设备从第二时段开始周期性地广播第一信道信息，网络设备在第二时段之后的第三时段发送更新指示信息，该更新指示信息用于通知信道信息更新，网络设备在第三时段之后的第四时段发送第三信道信息。网络设备在第二时段开始至第三时段为止均周期性地广播第一信道信息。
基于以上所述，在本申请实施例中，网络设备在一个时段内使用一个跳频图案发送数据。例如，网络设备在第二时段之前使用第二跳频图案发送数据，网络设备从第二时段开始使用第一跳频图案发送数据，直到跳频图案再次更新。同样的，终端设备在一个时段内使用一个跳频图案发送数据。
可选地，该第一时段和第二时段为相邻的两个时段。进一步地可选地，该第一时段和第二时段可以为多个时间周期中相邻的两个时间周期。
具体地，网络设备和终端设备可以预先约定该时间周期，也可以是协议规定该时间周期，还可以是网络设备为终端设备配置该时间周期。例如，该方法200可以包括：
网络设备发送周期信息，所述周期信息用于为所述终端设备配置时间周期，所述周期信息具体用于指示第一时长以及第一时长对应的边界，所述边界包括起始位置或结束位置，该时间周期的时长为第一时长，该时间周期的边界为第一时长对应的边界。
假设，该周期信息指示第一时长为五个子帧，该周期信息还用于指示第一时长对应的边界为子帧#0。该时间周期的时长为五个子帧，该时间周期的边界为子帧#0以及子帧#5。该第一时段可以为子帧#0-子帧#4，该第二时段可以为子帧#5-子帧#9。
也就是说，假设网络设备通过信道检测发现某个信道不可用，网络设备可以在时间周期#n(n>0)发送更新指示信息，在时间周期#(n+1)广播第一信道信息，在时间周期#(n+1)开始根据第一信道集合进行数据传输。或，假设网络设备通过信道探测发现某个信道不可用，可以在时间周期#n发送更新指示信息，在时间周期#(n+1)发送信道指示信息以及第一信道信息，在时间周期#(n+1)开始使用第一信道集合进行数据传输。
可选地，该第一时长大于或等于用于传输同步信号的信道的返回周期。
应理解，网络设备在用于传输同步信号的信道上周期性地发送信息。也就是说，网络设备在用于传输同步信号的信道上发送信息#1之后，需要间隔一段时间才可以再次发送信息。该间隔的时间为用于传输同步信号的信道的返回周期。
若第一时长小于该返回周期，用于传输同步信号的信道在到达第一时长时，该用于传输同步信号的信道可能无法发送第一信道信息。基于此，该第一时长大于或等于用于传输同步信号的信道的返回周期，有利于网络设备高效地发送第一信道信息。
可选地，该第一时长是寻呼周期的整数倍，
应理解，网络设备周期性地发送寻呼消息。也就是说，网络设备发送寻呼消息#1之后，需要间隔一段时间才可以再次发送寻呼消息。该间隔的时间为寻呼周期。
若第一时长小于寻呼周期，假设网络设备确定信道信息更新，网络设备可能无法发送携带更新指示信息的寻呼消息。基于此，该第一时长大于或等于寻呼周期，有利于网络设备高效地向终端设备通知信道信息更新。
