下面对本申请实施例中所使用到的一些通信名词或术语进行解释说明，该通信名词或术语也作为本申请发明内容的一部分。
一、锚点载波
在窄带物联网(narrow band internet of things，NB-IoT)系统中，对于频分双工(frequency division duplex，FDD)：锚点载波指的是终端设备假设有窄带主同步信号(narrowband primary synchronization signal，NPSS)、窄带辅同步信号(narrowband secondary synchronization signal，NSSS)、窄带物理广播信道(narrowband physical broadcast channel，NPBCH)、窄带系统信息块(system information block-NB，SIB-NB)传输的载波；非锚点载波指的是终端设备假设没有NPSS、NSSS、NPBCH和SIB-NB传输的载波。
在NB-IoT系统中，对于时分双工(time division duplex，TDD)：锚点载波指的是终端设备假设有NPSS、NSSS和NPBCH传输的载波；非锚点载波指的是终端设备假设没有NPSS、NSSS和NPBCH传输的载波。
示例的，如图4所示，锚点载波的系统带宽可为180kHz，该锚点载波上可有NPSS、NSSS、NPBCH以及SIB-NB传输。示例的，仍可参照图4所示，帧m中可包括10个子帧，索引依次为0至9。子帧0可用于传输NPBCH，子帧4可用于传输SIB-NB，子帧5可用于传输NPSS，子帧9可用于传输NSSS。帧m+1可包括10个子帧，索引依次为0至9。子帧0可用于传输NPBCH，子帧5可用于传输NPSS。
二、窄带和宽带
在增强型机器类通信(enhanced machine type communication,eMTC)系统中，窄带(narrowband)指的是频域上6个不重叠的物理资源块。宽带(wideband)指的是频域上4个不重叠的窄带。所述物理资源块可在频域上占用12个连续的子载波。其中，在一个给定系统带宽内，窄带和宽带的数量以及索引方式可以参照3GPP TS 36.211中5.2.4节和6.2.7 节中的记载，在此不予赘述。
三、锚点窄带与非锚点窄带：
本申请实施例中，锚点窄带指的是终端设备假设有同步信号传输的窄带；或者锚点窄带指的是终端设备执行初始连接建立过程或发起连接重建过程所占用的窄带，或者在切换过程中指示为锚点窄带的窄带。
本申请实施例中，非锚点窄带指的是终端设备假设没有同步信号传输的窄带；或者非锚点窄带指的是可以在建立RRC连接时配置，并且可以用于提供额外的无线资源的窄带。
四、锚点宽带与非锚点宽带：
本申请实施例中，锚点宽带指的是终端设备假设有同步信号传输的宽带；或者锚点宽带指的是终端设备执行初始连接建立过程或发起连接重建过程所占用的宽带，或者在切换过程中指示为锚点宽度的宽带。
本申请实施例中，非锚点宽带指的是终端设备假设没有同步信号传输的宽带；或者非锚点宽带指的是可以在建立RRC连接时配置，并且可以用于提供额外的无线资源的宽带。
五、控制信道元素(control channel element，CCE)
对于NB-IoT系统，CCE还可称为窄带控制信道元素(narrow control channel element，NCCE)，NCCE可由一个或多个资源元素(resource element，RE)组成。或者，还可描述为：1个NCCE，由一个子帧内的6个连续的子载波组成。比如，一个子帧中包括12个子载波，索引分别为0至11，CCE0可占用子载波0至子载波5，CCE1可占用子载波6至子载波11。或者，可以描述为：由于一个资源块(resource block，RB)由一个子帧内连续的12个子载波组成，因此，2个NCCE可组成一个RB。
示例的，如图5所示，配置载波为3个RB，每个RB的带宽为180kHz，3个RB共占用3*180kHz。在上述配置载波上，可划分6个NCCE，索引依次为#0至#5。每两个NCEE可组成一个RB。比如，NCCE#0和NCCE#1可组成一个RB，NCCE#2和NCCE#3可组成另一RB，NCCE#4和NCCE#5可组成一RB等。
六、聚合等级(aggregation level，AL)
在NB-IoT系统中，窄带物理下行控制信道(narrow physical downlink control channel,NPDCCH)可支持不同的聚合等级(aggregation level，AL)。示例的，如表1所示，NPDCCH所支持的聚合等级可包括{0，1，2}等。当聚合等级为0时，NPDCCH由1个NCCE组成。当聚合等级为1时，NPDCCH由2个NCCE组合。当聚合等级为2时，NPDCCH由3个NCCE组成。可以理解的是，上述表1中的记载，仅为示例说明，并不作为对本申请的限定。比如，当聚合等级为2时，NPDCCH也可以由4、5或者6个NCCE组成。
示例的，网络设备可根据信道质量等因素，决定当前NPDCCH所使用的聚合等级。例如，如果NPDCCH是发送给下行信道质量很好的终端设备(比如，位于小区中心的终端设备)，则网络设备可使用1个NCCE来发送该NPDCCH；如果NPDCCH是发送给下行信道质量很差的终端设备(比如，位于小区边缘的终端设备)，则网络设备可使用6个NCCE来发送该NPDCCH，以达到足够的健壮性。

七、覆盖等级
覆盖等级也称为覆盖增强等级、增强覆盖等级、重复等级或重复次数等。以NB-IoT系统为例，针对窄带物理随机接入信道(narrowband physical random access channel，NPRACH)引入覆盖等级的概念，每一个随机接入资源会映射到一个NPRACH覆盖等级，且最多支持三个NPRACH覆盖等级，分别为覆盖等级0、覆盖等级1和覆盖等级2。其中，从覆盖等级0开始，随机接入资源和NPRACH覆盖等级的映射随着NPRACH重复次数增加。比如，覆盖等级0关联的随机接入资源中NPRACH重复次数<覆盖等级1关联的随机接入资源中NPRACH重复次数<覆盖等级2关联的随机接入资源中NPRACH重复次数等。NPRACH的重复次数可为网络设备配置的。示例的，网络设备可通过随机接入重复次数(num Repetitions Per Preamble Attempt)参数为终端设备配置NPRACH的重复次数。
需要说明的是，本申请实施例中的覆盖等级，可指终端设备随机接入成功时的NPRACH覆盖等级。或者，可指终端设备开始随机接入过程中的NPRACH覆盖等级。或者，可指距离网络设备发送第一指示信息在时间上最近的，且随机接入过程成功时的NPRACH覆盖等级。关于第一指示信息可参见下述图6或图8所示流程中的记载。
