具体实施方式
本申请应用于NB-IoT，NB-IoT包括NB-IoT终端和NB-IoT基站。其中窄带(NB)是指对于NB-IoT终端来说，其只需要在180kHz的窄带内进行发送和接收；相应的，对于NB-IoT基站来说，其只需要在180kHz的窄带内与同一NB-IoT终端进行通信。
其中，NB-IoT的部署方式可以包括以下三种：

需要说明的是，本申请中的NB-IoT基站的功能可以通过现有已部署蜂窝网络中的基站来实现；本申请中的NB-IoT终端可以为物联网中进行物物通信的终端。
由于NB-IoT的传输带宽非常窄，因此存在频率分集增益较小的问题。

NB-IoT的信道传输方法实施例二
可选的，在本申请NB-IoT的信道传输方法实施例一的基础上，步骤101具体可以包括：NB-IoT基站确定信道的初始频域位置、跳频频率间隔及跳频时间间隔。
相应的，对于NB-IoT终端侧来说，NB-IoT终端确定信道的跳频信息，具体可以包括：NB-IoT终端确定信道的初始频域位置、跳频频率间隔及跳频时间间隔
可选的，NB-IoT基站确定信道的初始频域位置，具体可以包括：所述NB-IoT基站根据所述信道所处小区的小区标识ID，确定所述信道的初始频域位置；或者，所述NB-IoT基站在所有未被分配的频域位置中，随机选择所述信道的初始频域位置。
可选的，所述NB-IoT基站确定信道的跳频时间间隔，具体可以包括：所述NB-IoT基站根据所述信道的类型，确定所述跳频时间间隔；或者，所述NB-IoT基站根据所述NB-IoT终端所处的覆盖等级，确定所述跳频时间间隔；或者，所述NB-IoT基站从间隔集合中选择一个间隔，作为所述跳频时间间隔。
可选的，所述NB-IoT基站确定信道的跳频频率间隔，具体包括：所述NB-IoT基站根据所述NB-IoT的系统带宽，确定所述跳频频率间隔；或者，所述NB-IoT基站从频率集合中选择一个频率，作为所述跳频频率间隔。

可选的，所述NB-IoT终端确定信道的跳频时间间隔，包括：所述NB-IoT终端根据所述信道的类型，确定所述跳频时间间隔；或者，所述NB-IoT终端根据所述NB-IoT终端所处的覆盖等级，确定所述跳频时间间隔；或者，所述NB-IoT终端根据所述NB-IoT基站发送的第二通知信令，确定所述跳频时间间隔，所述第二通知信令用于指示所述跳频时间间隔。

需要说明的是，所述第一通知信令、所述第二通知信令和所述第三通知信令可以为同一通知信令，或者也可以为不同的通知信令。
以下，对不同信道的跳频信息的确定方式进行举例说明。
1、窄带物理广播信道(Narrow Band-Physical Broadcast channel，NB-PBCH)。
其中，NB-PBCH的初始频域位置可以通过信道所处小区的小区标识ID来确定，NB-PBCH的跳频时间间隔和跳频频率间隔可以为预设值，该预设值可以为相关协议规定的值。
需要说明的是，在带内部署场景下，由于NB-IoT终端与NB-IoT基站之间进行 NB-PBCH信道传输时，NB-IoT终端不能确定NB-IoT的系统带宽；因此可以假设为最小带宽进行NB-PBCH跳频。例如，假设最小带宽为3MHz(对应15个PRB)，并且由于LTE系统最中心的6个PRB用于传输LTE系统的同步信号或广播信道，因此NB-PBCH可以在以NB-IoT中心频点为中心的3MHz的带宽范围内，除LTE系统最中心的6个PRB外的带宽范围内进行跳频。而对于保护带部署场景下，NB-IoT终端在进行网络同步时的初始频率偏移可以指示出可以LTE的系统带宽。
2、承载窄带系统消息块1的信道(Narrow Band-System Information Block 1，NB-SIB1)。
由于NB-IoT终端与NB-IoT基站之间进行NB-SIB1传输之前，已经通过NB-PBCH承载的主消息块(Master Information Block，MIB)信息获得了NB-IoT的系统带宽，因此NB-SIB1可以在NB-IoT的传输带宽内进行跳频。
当NB-IoT基站需要通过通知信令指示NB-SIB1的初始频域位置、跳频时间间隔和跳频频率间隔时，可以通过NB-PBCH承载的MIB信息实现。
3、窄带物理下行控制信道(Narrow Band-Physical Downlink Control Channel，NB-PDCCH)。
当NB-IoT基站需要通过通知信令指示NB-PDCCH的初始频域位置、跳频时间间隔和跳频频率间隔时，可以通过NB-SIB1信息或无线资源控制(Radio Resource Control，RRC)信令实现。
4、窄带物理下行共享信道(Narrow Band-Physical Downlink Shared Channel，NB-PDSCH)。
当NB-IoT基站需要通过通知信令指示NB-PDSCH的初始频域位置、跳频时间间隔和跳频频率间隔时，可以通过RRC信令或通过NB-PDCCH承载的下行控制信息(Downlink Control Information，DCI)信令实现。
5、窄带物理上行共享信道(Narrow Band-Physical Uplink Shared Channel，NB-PUSCH)。
当NB-IoT基站需要通过通知信令指示NB-PUSCH的初始频域位置、跳频时间间隔和跳频频率间隔时，可以通过RRC信令或通过NB-PDCCH承载的DCI信令实现。
本实施例中，通过NB-IoT终端(或NB-IoT基站)确定信道的初始频域位置、跳频频率间隔及跳频时间间隔；使得NB-IoT终端(或NB-IoT基站)能够获得跳频信息，从而使得NB-IoT终端(或NB-IoT基站)可以根据跳频信息进行跳频。

图2为本申请NB-IoT的信道传输方法实施例三的组内组间跳频示意图，其中，以M和N都为3为例进行说明。其中，黑色框表示信道跳频后的时域位置和频域位置。
可选的，M可以由NB-IoT基站与NB-IoT终端预先约定，并进一步根据NB-IoT的系统带宽确定N；例如，假设一个PRB组由3个连续的PRB组成，在10MHz带宽的NB-IoT系统中包含50/3＝16个PRB组。
或者，可选的，N可以根据NB-IoT的系统带宽确定，在确定N之后，进一步的根据N以及NB-IoT的系统带宽确定M。
本实施例中，通过对PRB进行分组，并实现组内跳频和组间跳频的两级跳频方式，可以实现在有限的传输时间内在更大的频率范围的跳频。同时，通过将NB-IoT系统中组的大小配置成与增强机器式通信(enhanced Machine Type Communication，eMTC)系统中组的大小相同，可以更好实现NB-IoT系统与eMTC系统共存。
