具体实施方式
图1为终端设备使用初始BWP和专用BWP的示例图，如图1所示，终端设备在RRC 空闲态和RRC非激活态时，通过初始BWP接入网络设备。在进入RRC连接态后，网络设备为终端设备配置三个专用BWP，包括BWP1、BWP2和BWP3，在t1时刻，网络设备为终端设备激活BWP1，在t2时刻，网络设备为终端设备激活BWP2，在t3时刻，网络设备为终端设备激活BWP3。在同一时刻，终端设备仅有一个激活的专用BWP。
在5G通信系统中，初始BWP可以为5MHz、10MHz、15MHz或20MHz。物联网场景包括大量的终端设备，在这种场景下，可能存在大量的终端设备同时接入网络设备的情况。作为一种可能的设计，对于处于RRC空闲态或RRC非激活态的终端设备，网络设备按照相同传输配置利用这些初始BWP与各终端设备进行信息传输。在这种方式中，网络设备所基于的传输配置可能与终端设备的实际需求不匹配，进而导致时频资源的浪费和/或终端设备的功耗的增加。
例如，在物联网场景中，由于终端设备能力和复杂度的降低，终端设备的上行发送的覆盖(coverage)和下行接收的覆盖会缩小。例如，对于正常终端设备，终端设备可以在小区边缘正常通信，但对于降低能力(reduced capability,Red-Cap)的终端设备，由于其接收天线、发射天线、功耗等的减少，小区边缘的Red-Cap终端设备可能无法正常通信。为此，需要为小区边缘的终端设备引入重复传输(repetition)机制，即网络设备或终端设备在发送信号时，对同一信号或消息或信令或数据进行重复传输，以扩大上行发送和下行发送的覆盖。但由于不同的终端设备其所处位置或运动状态可能不同，例如，一些终端设备处于小区边缘，另一些终端设备处于小区中心，一些终端设备移动，另一些终端设备静止等，如果均应用重复传输机制，则会增加时频资源的消耗。例如，网络设备在向处于小区中心且静止的终端设备发送寻呼消息时，不需要应用重复传输，向处于小区边缘且静止的终端设备发送寻呼消息时，需要应用重复传输，而在上述的方法中，网络设备不区分这两类终端设备，为保证能够寻呼到这两类终端设备，网络设备对小区内的各终端设备均应用重复传输，对于网络设备而言，这种重复传输的方式可能会造成时频资源的浪费。为了阐述简明，所述重复传输是指通过重复发送同一消息，来增加接收端的接收成功率，在以下实施例中不再赘述。需要说明的是，本申请不限定进行重复传输的终端设备类型，也不限定进行重复传输的终端设备位置。
又例如，为减少终端设备的功耗，5G通信系统支持非连续接收(discontinuous reception，DRX)机制。当终端设备没有配置DRX时，终端设备与网络设备之间没有上下行业务数据传输的情况下，终端设备处于RRC空闲态或RRC非激活态。在该状态下，对于终端设备，由于来自于网络设备的下行数据传输不可预期，终端设备需要一直监听网络设备可能发送的寻呼消息。在大多数时间里，网络设备不会寻呼终端设备，这就导致终端设备在监听寻呼消息时的功率消耗。当终端设备配置DRX时，终端设备可以周期性醒来监听寻呼消息。图2为DRX周期的示例，如图2所示，终端设备醒来的周期为DRX周期，唤醒时长为Dur，终端设备在Dur时间内监听寻呼消息，终端设备不监听寻呼消息的时长为Opp。
目前，DRX的配置方式可以包括两种，一种是网络设备通过广播消息配置DRX周期，包含rf32，rf64，rf128，rf256，其中rf为无线帧(radio frame)，一个无线帧为10ms，不同的网络设备可以广播不同的DRX周期，另一种方式是核心网为终端设备配置专用的DRX周期，同样包含上述取值。作为一种可能的设计，若终端设备配置了专用的DRX周期，则终端设备使用专用的DRX和广播的DRX周期中较小的DRX周期。这种设计使得有较 高功耗要求的终端设备不能实现被配置较大的DRX周期，增大了终端设备的功耗。
考虑到上述的设计中网络设备基于相同的传输配置与终端设备进行信息传输所导致的时频资源浪费和/或终端设备功耗增加的问题，本申请实施例基于终端设备的辅助信息选择与终端设备实际需要相匹配的方式进行信息传输，从而避免时频资源的浪费以及终端设备功耗的增加。
图3是本申请实施例应用的移动通信系统的架构示意图。如图3所示，该移动通信系统包括核心网设备210、网络设备220和至少一个终端设备(如图3中的终端设备230和终端设备240)。终端设备通过无线的方式与网络设备相连，网络设备通过无线或有线方式与核心网设备连接。核心网设备与网络设备可以是独立的不同的物理设备，也可以是将核心网设备的功能与网络设备的逻辑功能集成在同一个物理设备上，还可以是一个物理设备上集成了部分核心网设备的功能和部分的网络设备的功能。终端设备可以是固定位置的，也可以是可移动的。图3只是示意图，该通信系统中还可以包括其它网络设备，如还可以包括无线中继设备和无线回传设备，在图3中未画出。本申请的实施例对该移动通信系统中包括的核心网设备、网络设备和终端设备的数量不做限定。
网络设备是终端设备通过无线方式接入到该移动通信系统中的接入设备，可以是节点B(NodeB)、演进型节点B(eNodeB)、5G移动通信系统中的接入节点、未来移动通信系统中的接入节点或WiFi系统中的接入节点等，本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
终端设备也可以称为终端Terminal、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self-driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
网络设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对网络设备和终端设备的应用场景不做限定。
示例性的，本申请实施例可以适用于5G通信系统的物联网场景中，或者，适用于4G通信系统的增强机器类型通信(enhanced machine type communication，eMTC)场景或窄带物联网(narrowband Internet of things，NB-IoT)场景中。与5G通信系统的物联网场景类似的，在eMTC以及NB-IoT场景中，存在大量低终端能力、低复杂度和低功耗的终端设备需要接入网络设备。
在说明本申请实施例的技术方案之前，首先对本申请实施例涉及的技术术语进行解释。
1、RRC空闲态
在RRC空闲态，终端设备与网络设备之间不存在RRC层的逻辑连接，终端设备不能与网络设备进行上行或下行的数据和信令传输，仅能接收网络设备发送的寻呼消息和系统信息。同时，在RRC空闲态，终端设备与核心网之间也不存在RRC层的逻辑连接，核心网和网络设备均不保存终端设备的上下文。当需要寻呼终端设备时，寻呼消息由核心网发 起。
2、RRC非激活态
在RRC非激活态，终端设备与网络设备之间不存在RRC层的逻辑连接，终端设备不能与网络设备进行上行或下行的数据和信令传输，仅能接收网络设备发送的寻呼消息和系统信息。同时，在RRC非激活态，终端设备与核心网之前存在RRC层的逻辑连接，网络设备和核心网均保存终端设备的上下文。当需要寻呼终端设备时，由核心网将寻呼涉及的数据发送至网络设备，网络设备再发起寻呼消息。
3、DRX
DRX可以分为空闲态DRX(Idle DRX,I-DRX)和连接态DRX(Connected DRX,C-DRX)。I-DRX指终端设备不需要连续监听寻呼消息，可以达到降低终端设备功耗的目的。C-DRX指终端设备不需要连续监听调度上行/下行数据的控制信息，可以达到降低终端设备功耗的目的。
