本申请实施例可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、先进的长期演进(Advanced long term evolution，LTE-A)系统、新无线(New Radio，NR)系统、NR系统的演进系统、免授权频谱上的LTE(LTE-based access to unlicensed spectrum，LTE-U)系统、免授权频谱上的NR(NR-based access to unlicensed spectrum，NR-U)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、无线局域网(Wireless Local Area Networks，WLAN)、无线保真(Wireless Fidelity，WiFi)、下一代通信系统或其他通信系统等。
通常来说，传统的通信系统支持的连接数有限，也易于实现，然而，随着通信技术的发展，移动通信系统将不仅支持传统的通信，还将支持例如，设备到设备(Device to Device，D2D)通信，机器到机器(Machine to Machine，M2M)通信，机器类型通信(Machine Type Communication，MTC)，以及车辆间(Vehicle to Vehicle，V2V)通信等，本申请实施例也可以应用于这些通信系统。
可选地，本申请实施例中的通信系统可以应用于载波聚合(Carrier Aggregation，CA)场景，也可以应用于双连接(Dual Connectivity，DC)场景，还可以应用于独立(Standalone，SA)布网场景。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
本申请实施例结合终端设备和网络设备描述了各个实施例，其中：终端设备也可以称为用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备可以是WLAN中的站点(STAION，ST)，可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)设备、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备以及下一代通信系统，例如，NR网络中的终端设备或者未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的终端设备等。
作为示例而非限定，在本申请实施例中，该终端设备还可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
网络设备可以是用于与移动设备通信的设备，网络设备可以是WLAN中的接入点(Access Point，AP)，GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB，NB)，还可以是LTE中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继站或接入点，或者车载设备、可穿戴设备以及NR网络中的网络设备或者基站(gNB)或者未来演进的PLMN网络中的网络设备等。
在本申请实施例中，网络设备为小区提供服务，终端设备通过该小区使用的传输资源(例如，频域资源，或者说，频谱资源)与网络设备进行通信，该小区可以是网络设备(例如基站)对应的小区，小区可以属于宏基站，也可以属于小小区(Small cell)对应的基站，这里的小小区可以包括：城市小区(Metro cell)、微小区(Micro cell)、微微小区(Pico cell)、毫微微小区(Femto cell)等，这些小小区具有覆盖范围小、发射功率低的特点，适用于提供高速率的数据传输服务。
5G NR系统定义了包括卫星网络在内的NTN系统部署场景。NTN一般采用卫星通信的方式向地面用户提供通信服务。相比地面蜂窝网通信，卫星通信具有很多独特的优点。首先，卫星通信不受用户地域的限制，例如一般的陆地通信不能覆盖海洋、高山、沙漠等无法搭设通信设备或由于人口稀少而不做通信覆盖的区域，而对于卫星通信来说，由于一颗卫星即可以覆盖较大的地面，加之卫星可以围绕地球做轨道运动，因此理论上 地球上每一个角落都可以被卫星通信覆盖。其次，卫星通信有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖到，从而使这些地区的人们享受到先进的语音通信和移动互联网技术，有利于缩小与发达地区的数字鸿沟，促进这些地区的发展。再次，卫星通信距离远，且通信距离增大通讯的成本没有明显增加；最后，卫星通信的稳定性高，不受自然灾害的限制。
通信卫星按照轨道高度的不同分为低地球轨道(Low-Earth Orbit，LEO)卫星、中地球轨道(Medium-Earth Orbit，MEO)卫星、地球同步轨道(Geostationary Earth Orbit，GEO)卫星、高椭圆轨道(High Elliptical Orbit，HEO)卫星等等。
例如，LEO卫星高度范围为500km～1500km，相应轨道周期约为1.5小时～2小时。用户间单跳通信的信号传播延迟一般小于20ms。最大卫星可视时间20分钟。信号传播距离短，链路损耗少，对用户终端的发射功率要求不高。
又例如，GEO卫星轨道高度为35786km，围绕地球旋转周期为24小时。用户间单跳通信的信号传播延迟一般为250ms。
终端设备启动或重启drx-InactivityTimer的条件为：
如果终端接收到一个指示下行或者上行初始传输的PDCCH，则终端启动或者重启drx-InactivityTimer。
终端启动和停止drx-RetransmissionTimerDL的条件为：
当终端设备接收到一个指示下行传输的PDCCH，或者当终端在配置的下行授权资源上接收到一个MAC PDU，则终端停止该HARQ进程对应的drx-RetransmissionTimerDL。终端在完成针对这次下行传输的HARQ进程反馈的传输之后启动该HARQ进程对应的drx-HARQ-RTT-TimerDL。
如果终端设备的某个HARQ对应的定时器drx-HARQ-RTT-TimerDL超时，并且使用这个HARQ进程传输的下行数据解码不成功，则终端启动这个HARQ进程对应的drx-RetransmissionTimerDL。
终端启动和停止drx-RetransmissionTimerUL的条件为：
当终端接收到一个指示上行传输的PDCCH，或者当终端在配置的上行授权资源上发送一个MAC PDU，则终端停止该HARQ进程对应的drx-RetransmissionTimerUL。终端在完成这次PUSCH的第一次重复传输(repetition)之后启动该HARQ进程对应的drx-HARQ-RTT-TimerUL。
如果终端的某个HARQ对应的定时器drx-HARQ-RTT-TimerUL超时，则终端启动这个HARQ进程对应的drx-RetransmissionTimerUL。
与传统NR采用的蜂窝网络相比，NTN中终端设备与卫星之间的信号传播时延大幅增加，为了在不增加HARQ进程数目的情况下保证数据传输连续性，可以设计开启或者关闭HARQ的方案。
如果HARQ功能关闭，则终端设备不需要向网络设备发送针对物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的HARQ反馈。
在关闭HARQ反馈的情况下，为了保证数据传输可靠性，仍然支持HARQ重传。
需要说明的是，如果关闭了HARQ，由于没有了针对HARQ的反馈，网络设备可以在接收到终端设备的上行传输或者针对下行传输的反馈之前继续调度该上行传输或者下行传输的重传。对于终端设备而言，对于上行数据传输，终端设备可以在发送完本次上行传输之后继续接收上行重传调度；对于下行数据传输，终端设备可以在完成对本次下行传输的解码之前继续接收下行重传调度。因此，在关闭HARQ的情况下可以不再需要上行非连续接收HARQ往返传输时间定时器(Uplink Discontinuous Reception HARQ round trip time Timer，drx-HARQ-RTT-TimerUL)和下行非连续接收HARQ往返传输时间定时器(Downlink Discontinuous Reception HARQ round trip time Timer，drx-HARQ-RTT-TimerDL)。同时由于终端设备不需要等待网络侧处理接收情况再调度 重传，因此上行非连续接收重传定时器(Uplink Discontinuous Reception Retransmission Timer，drx-RetransmissionTimerUL)和下行非连续接收重传定时器(Downlink Discontinuous Reception Retransmission Timer，drx-RetransmissionTimerDL)也不再需要，即网络侧的重传调度可以是早于网络侧对下行数据传输的肯定应答(Acknowledgement，ACK)或者否定应答(Negative Acknowledgement，NACK)反馈或者上行数据传输的接收时刻。
针对以上技术问题，本申请设计了一种在关闭HARQ反馈的情况下终端设备非连续接收物理下行控制信道(Physical Downlink Control Channel，PDCCH)的方案。针对关闭HARQ反馈功能的HARQ进程，通过关闭drx-HARQ-RTT-TimerUL、drx-HARQ-RTT-TimerDL、drx-RetransmissionTimerUL和drx-RetransmissionTimerUL，使得终端设备不再等待网络侧的数据包检测结果，通过引入非连续接收(Discontinuous Reception，DRX)非激活定时器(inactivity timer)的重启，保证了终端设备能够在动态调度上行传输/下行传输和预配置的上行传输/下行传输后能够继续监听PDCCH，便于在NTN网络中终端设备能够对网络设备持续调度重传或新传的连续接收。
以下详细阐述本申请针对上述技术问题而设计的在关闭HARQ反馈的情况下终端设备非连续接收PDCCH的方案。
