  • 3GPP has introduced the power saving research topic in the NR rel-16 version. The purpose is to study the possibility of terminal equipment in various states (including connection state, idle state). Power consumption reduction schemes in the inactive state and the inactive state. Among them, how to save the power consumption of the terminal device in the connected state is a research focus.
  • DRX Discontinuous Reception
  • the terminal device starts an inactive timer (inactive timer) in the active state of the connected state, and the terminal device continuously tries to receive the physical downlink control channel (PDCCH). If the terminal device receives the scheduling downlink control information (DCI) on the PDCCH, the terminal device will restart the inactive timer. If the terminal device does not receive the DCI within a period of time and the inactive timer times out, the terminal device will enter The inactive state of DRX.

  • 3GPP has also designed a wake-up signal (WUS), which is introduced in the narrowband internet of things (NB-IoT) to reduce the power consumption of terminal equipment.
  • WUS wake-up signal
  • the control signal is mainly used in the paging mechanism in the idle state.
  • the terminal device In the idle state, the terminal device is generally in a dormant state, but the terminal device needs to wake up every time to try to receive a paging (Paging).
  • Paging the time when the terminal device is awakened to receive a paging is called a paging opportunity (PO).
  • PO paging opportunity
  • the network device does not send Paging to the terminal device at every PO.
  • the terminal device wakes up and receives Paging at the PO most of the time, which is an invalid operation and increases the power consumption of the terminal device. For this reason, WUS is introduced in the NB-IoT system. If a network device does send Paging to a terminal device in a PO, the network device will send WUS before the PO arrives, otherwise the network device will not send WUS. Correspondingly, the terminal device will try to receive WUS before the PO arrives. If the terminal device receives WUS, the terminal device will confirm that there is a Paging message in the next PO, and the terminal device will continue to try to receive Paging.
  • the terminal device will consider that there is no Paging message in the next PO, and the terminal device will not try to receive Paging and continue to sleep. Since the power consumption and complexity of the terminal device when receiving WUS is much smaller than the power consumption and complexity of the terminal device when it tries to receive Paging, and the probability of the network device sending Paging in the idle state of the terminal device is not high, it is determined by whether the WUS is received or not. Determining whether the terminal device wakes up can greatly save the power consumption of the terminal device.
  • NR Rel-16 considers introducing a PDCCH-based wake-up signal (PDCCH-based wake-up signal, PDCCH WUS or WUS for short), which means that WUS is carried by PDCCH.
  • the terminal device can turn on the low power consumption mode in a few time slots before the arrival of DRX_ON and try to receive the PDCCH WUS sent by the network device. If the terminal device detects the PDCCH WUS within this time period, it will be in the corresponding DRX_ON time period Wake up to detect the PDCCH. On the contrary, if the terminal device does not receive the PDCCH WUS, the terminal device will consider that there is no PDCCH scheduling in the next DRX_ON, and the terminal device will not try to receive the DRX_ON and continue to sleep.

  • This PDCCH WUS is called a UE-specific PDCCH wake-up signal (UE-specific PDCCH WUS).
  • UE-specific PDCCH WUS can carry a large number of parameter configurations, it occupies an entire PDCCH, and the resource overhead is too large. Therefore, the PDCCH WUS can also be a signal sent to multiple UEs. That is, a PDCCH DCI contains the WUS signals and related configuration information of multiple UEs. As shown in Figure 2, this kind of PDCCH WUS is called group-based. Wake-up signal (Group-based WUS). Group-based WUS can reduce the overhead of downlink control signaling, but the corresponding configuration information that can be sent to each user equipment is correspondingly reduced.

Show. If the terminal device detects the PDCCH WUS within the WUS search time, the terminal device wakes up and detects the PDCCH within the DRX_ON time period corresponding to the WUS search time. If the UE does not detect the PDCCH WUS within the WUS search time, the UE is in the WUS The DRX_ON period corresponding to the search time continues to maintain the dormant state, and the PDCCH will not be detected.
  • the WUS search time window configured by the network equipment and the search space set configured are independent of each other, that is, the terminal device determines that the WUS search time window only depends on the length of the time window itself, the time offset, and the start time of DRX_ON, which is different from the search space set.
  • the configured time period parameters are completely independent. In some cases, for example, when the transmission period of the search space is longer than the length of the WUS search time window, it may happen that the PDCCH WUS transmission timing falls outside the WUS search window, so that there is no PDCCH WUS in the WUS search window.

  • the network device must configure the search space set transmission period to be less than or equal to the length of the WUS search time window to ensure that the WUS search time window will have a PDCCH WUS transmission opportunity.

一种通信方法、装置及计算机可读存储介质
相关申请的交叉引用
本申请要求在2019年08月30日提交中国专利局、申请号为PCT/CN2019/103855、申请名称为“一种通信方法、装置及计算机可读存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置及计算机可读存储介质。
背景技术
目前，终端设备可以在唤醒信号(Wake-up signal，WUS)搜索时间窗检测基于物理下行控制信道的唤醒信号(physical downlink control channel-based wake-up signal，也称为PDCCH WUS)，终端设备如果在WUS搜索时间窗内在检测到PDCCH WUS，则在不连续接收(Discontinuous Reception，DRX)状态的唤醒模式On Duration时间段内检测下行控制信道，终端设备如果在WUS搜索时间窗内在未检测到PDCCH WUS，则在DRX状态的On Duration时间段内保持休眠状态，即不检测PDCCH。
PDCCH WUS的发送时机和PDCCH一样，可以在预先定义的搜索空间集合(search space set)中发送，搜索空间集合在时频资源上具有预先配置好的带宽以及发送周期。现有技术中，为了节省下行空口资源的开销，网络设备一般将search space set发送周期设置地大于WUS搜索时间窗，但是这样的设置常常引起PDCCH WUS的发送时机落在WUS搜索窗口之外，由于WUS搜索窗口内不存在PDCCH WUS的发送时机，所以终端设备无法确定在何时去检测PDCCH WUS，且即便检测也肯定无法在WUS搜索时间窗口内检测到WUS，所以当On Duration到来时，终端设备不知道如何应对，进而导致数据的发送或者接收延迟。
另外，即便PDCCH WUS的发送时机刚好落在WUS搜索窗口内，但如果PDCCH WUS的发送时机位于终端设备执行带宽部分(bandwidth part，BWP)切换对应的切换延迟时间内，那么终端设备会由于射频收发功能中断，同样无法检测网络设备是否在WUS搜索时间窗内发送了PDCCH WUS，所以当On Duration到来时终端设备还是不知道如何应对，进而导致数据的发送或者接收延迟。
发明内容

具体实施方式
为了使本发明实施例的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施例作进一步地详细描述。
为了便于理解本发明实施例，下面对本申请的应用场景进行说明。
目前，第三代合作伙伴计划(3rd Generation Partnership Project，3GPP)标准组织目 前正在制定第5代蜂窝移动通信系统(5th Generation，5G)的协议标准，5G也被称为新空口(New Radio，NR)。与长期演进(Long Term Evolution，LTE)系统相比，NR支持更大的传输带宽，更多的收发天线阵列，更高的传输速率以及更灵活、粒度更小的调度机制。虽然基于上述特性NR提供更多的适用范围，但是却极大的增加了终端设备的功耗负担。为了降低终端设备的功耗，3GPP在NR rel-16版本中引入了功耗节省(Power saving)研究课题，其目的是研究使终端设备可在各种状态下(包括连接(connection)态，空闲态，以及非激活态)下可能的降功耗方案，其中，在连接态如何节省终端设备功耗是一个研究重点。
在LTE系统中，3GPP设计了不连续接收(Discontinuous Reception，DRX)机制来降低终端设备在连接态的功耗。在DRX机制中，终端设备在连接态的激活状态下，会启动一个非激活定时器(inactive timer)，终端设备不断尝试接收物理下行控制信道(physical downlink control channel，PDCCH)。如果终端设备接收到PDCCH上的调度下行控制信息(downlink control information，DCI)，终端设备会重启inactive timer，如果终端设备在一段时间内都未接收到DCI，使得inactive timer超时，则终端设备会进入DRX的非激活状态。
如图1所示，DRX状态下的基本时间单位为一个DRX cycle(DRX循环)，DRX cycle的时间长短为DRX周期，一个DRX cycle由一个休眠(Sleep)状态(即非激活状态)和On Duration(持续时间)状态组成。其中On Duration即唤醒模式也称为DRX_ON，当DRX cycle进入到On Duration时，终端设备将被唤醒并监听PDCCH，一旦在PDCCH中接收到了调度DCI，终端设备将重新启动inactive timer计时。如果最终inactive timer超时，终端设备将重新回到Sleep模式。Sleep状态即休眠模式，也称为DRX_OFF，处于Sleep模式下的终端设备可以完全关闭射频收发器和基带处理器等通信器件以降低功耗。
需要注意的是，一般情况下终端设备并不是在On Duration到来时才唤醒，而是会在On Duration到来前的几个时隙内先唤醒，并接收下行参考信号线进行时频偏同步，防止终端设备因为长时间休眠造成系统的时钟和工作频率与网络设备的时钟和工作频率出现偏差；同时终端设备也可以先尝试接收下行同步信号和更新系统消息，以防止终端设备从一个小区移动到另一个小区后系统消息出现偏差。
在LTE系统中，3GPP还设计了唤醒信号(Wake-up signal，WUS)，WUS是在窄带物联网(narrow band internet of things，NB-IoT)中引入的用以降低终端设备功耗的一种控制信号，主要应用在空闲状态的寻呼机制中。在空闲态中，终端设备一般情况下处于休眠状态，但终端设备需要每过一段时间唤醒来尝试接收寻呼(Paging)。其中，终端设备被唤醒接收寻呼的时间的被称为寻呼机会(paging occasion，PO)。在实际系统中，网络设备并不是在每个PO都会给终端设备发送Paging，因此终端设备在大部分时间中在PO唤醒接收Paging都属于无效操作，并且会增加终端设备的功耗。为此，NB-IoT系统中引入了WUS，如果在某一个PO中网络设备确实向终端设备发送了Paging，网络设备会在PO到来之前发送WUS，反之网络设备不会发送WUS。对应的，终端设备会在PO到来之前的时间尝试接收WUS，如果终端设备接收到了WUS，终端设备确认接下来的PO中存在Paging消息，终端设备会继续尝试接收Paging，反之，如果终端设备没有接收到WUS，终端设备将认为接下来的PO中不存在Paging消息，终端设备将不尝试接收Paging并继续休眠。由于终端设备接收WUS时的功耗和复杂度远小于终端设备尝试接收Paging时的功耗和复杂 度，而且网络设备在终端设备空闲态发送Paging的概率并不高，因此通过是否接收到WUS来确定终端设备是否唤醒可以极大的节省终端设备的功耗。
NR Rel-16考虑引入基于PDCCH的唤醒信号(PDCCH-based wake-up signal，简称为PDCCH WUS或者WUS)，也就是说WUS是通过PDCCH来承载。终端设备可以在DRX_ON到来前的几个时隙内开启低功耗模式，尝试接收网络设备发送的PDCCH WUS，终端设备如果在该时间段内检测到PDCCH WUS，则会在对应的DRX_ON时间段内唤醒，进而去检测PDCCH，反之，如果终端设备没有接收到PDCCH WUS，终端设备将认为接下来的DRX_ON中不存在PDCCH调度，终端设备将不尝试接收DRX_ON并继续休眠。
PDCCH WUS除了承载唤醒指示以外，还可以承载其他一些用于终端设备在功耗节省状态下的参数配置，例如：终端设备工作的BWP，终端设备可以驻留在一个带宽较窄的BWP来检测WUS，而WUS中可以指示终端设备唤醒后的工作BWP，该工作BWP的带宽较大，具有更高的数据传输速率。PDCCH WUS指示BWP切换的方法可以是PDCCH WUS中携带目标BWP ID，终端设备通过解析PDCCH WUS中的目标BWP ID，切换到新BWP上。
PDCCH WUS可以是发给单个用户设备(user equipment，UE)的信号，即PDCCH DCI只承载一个UE的WUS信号，这种PDCCH WUS被称为用户设备专用PDCCH唤醒信号(UE-specific PDCCH WUS)。UE-specific PDCCH WUS虽然能够承载大量的参数配置，但是会占用一整个PDCCH，资源开销太大。因此，PDCCH WUS也可以是发送给多个UE的信号，即一个PDCCH DCI中包含有多个UE的WUS信号和相关的配置信息，如图2所示，这种PDCCH WUS被称为基于组的唤醒信号(Group-based WUS)。Group-based WUS可以减少下行控制信令的开销，但对应的可以发给每个用户设备的配置信息也相应变少了。
PDCCH WUS的发送时机和PDCCH一样，可以在预先定义的搜索空间集合(search space set)中发送。搜索空间集合在时频资源上具有预先配置好的带宽以及发送周期。
搜索空间集合的发送周期可以配置为1个时隙到2560个时隙，在一个发送周期中，可以有一个或者连续几个时隙发送PDCCH WUS。在发送PDCCH WUS的每个时隙中，网络设备还可以配置发送PDCCH WUS的具体符号位置。其中一个PDCCH WUS发送时间可以占用一个时隙中的1到3个符号，这些符号可以被称为一个PDCCH WUS的检测时机(monitoring occasion)。UE只需要根据配置的search space set周期，以及PDCCH WUS出现在每个周期的时隙位置，每个时隙中符号的出现位置，以及持续符号数，就能确定PDCCH WUS的检测时机。例如，参见图3，为搜索空间集合的一个发送周期的示例，在图3所示的发送周期中，时隙1(slot1)中存在PDCCH WUS的检测时机。
需要说明的是，在高频(无线信号载频大于等于6G)的情况下，网络设备可以通过多个search space来发送PDCCH WUS，并且不同的search space可以具有不同的PDCCH monitoring occasion配置。例如，参见图4，网络设备通过两个搜索空间集合(第一搜索空间集合、第二搜索空间集合)来发送PDCCH WUS的示例，其中第一搜索空间集合的一个发送周期包括四个时隙，且PDCCH WUS的检测时机位于时隙1(slot1)中，第二搜索空间集合的一个发送周期包括3个时隙，且PDCCH WUS的检测时机位于时隙2(slot2)中。
3GPP在讨论PDCCH WUS时，确定PDCCH WUS的发送时间距离DRX_On的开始时间存在一个时间偏移(offset)，但具体的WUS发送时间尚没有达成结论。一种WUS发送时间的配置方法是：指定DRX_ON之前的一段时间(比如DRX_ON到来前的指定几个 时隙)为WUS搜索时间(在本文中也可以称为WUS搜索时间窗)，如图5所示。如果终端设备在WUS搜索时间内检测到了PDCCH WUS，则终端设备在该WUS搜索时间对应的DRX_ON时间段内唤醒并检测PDCCH，如果UE在WUS搜索时间内未检测到PDCCH WUS，则UE在该WUS搜索时间对应的DRX_ON时间段内继续维持休眠状态，将不检测PDCCH。
目前，网络设备配置WUS搜索时间窗和配置search space set相互独立，也即终端设备确定WUS搜索时间窗仅依赖于时间窗本身的长度、时间偏移量、以及DRX_ON的开始时间，与search space set配置的时间周期参数完全独立。在一些情况下，例如当search space的发送周期长度大于WUS搜索时间窗的长度时，就可能出现PDCCH WUS的发送时机落在WUS搜索窗口之外的情况，使得WUS搜索窗口内不存在PDCCH WUS的发送时机。由于WUS搜索窗口内不存在PDCCH WUS的发送时机，所以终端设备无法确定在何时去检测PDCCH WUS，且即便检测也肯定无法在WUS搜索时间窗口内检测到WUS，所以当DRX_ON到来时，终端设备不知道如何应对(无法确定是否要检测PDCCH)，因而导致数据的发送或者接收延迟的问题。
为防止该情况出现，网络设备必须将search space set的发送周期配置地小于或者等于WUS搜索时间窗的长度，才能保证WUS搜索时间窗会出现PDCCH WUS的发送时机。但这种配置要求会限制网络设备的灵活性，尤其是对于group-based PDCCH-WUS的情况，由于group-based WUS配置给一组UE，因此在search space set的每个发送周期都可能有UE需要被唤醒，过小的search space周期会引起基站发送大量PDCCH WUS，占用了下行空口资源，需要牺牲很大的系统开销。
另外，现有技术中终端设备在进行BWP切换时，存在一个切换延迟(BWP switch delay)时间，在切换延迟时间内，终端设备的射频收发功能会被中断，无法执行任何数据收发操作，所以在这种场景下，即便终端设备可以确定WUS搜索时间窗内存在PDCCH WUS的发送时机，但如果PDCCH WUS的发送时机位于终端设备执行BWP切换对应的切换延迟时间内，那么终端设备也没有能力去检测网络设备是否在WUS搜索时间窗内发送了PDCCH WUS，所以当DRX_ON到来时终端设备还是不知道如何应对(无法决定是否要检测PDCCH)，同样会导致数据的发送或者接收延迟的问题。
还有一种情况中，现有技术中终端设备如果工作在时分双工(Time Division Duplex)的模式下，终端设备通信的时隙可以被分为上行时隙，下行时隙等。其中上行时隙用于发送上行数据，上行控制信令以及参考信号等，下行时隙用于接收同步广播信道，下行控制信道，下行数据以及参考信号等。除去上行时隙和下行时隙，其余的时隙中的符号可以被配置为上行符号，下行符号以及灵活符号(flexible symbol)，其中灵活符号可以根据实际的调度情况被动态的用于下行接收或者上行传输，可以灵活调节上行或者下行的空口容量。但是，如果唤醒信号的发送时机和flexible symbol重合，为支持发送唤醒信号，该flexible symbol将必须被用于下行接收，因此降低了flexible symbol利用的灵活性。
鉴于此，本发明实施例提供一种通信方法，该方法用以在当终端设备由于配置的WUS搜索时间窗内不存在PDCCH WUS的发送时机、或者发生BWP切换等原因无法检测PDCCH WUS时，或者唤醒信号的发送时机和flexible symbol重合时，明确终端设备在DRX_ON到来时的行为，即使得终端设备在DRX_ON到来时唤醒并检测PDCCH。这样，一方面可以避免由于DRX_ON到来时终端设备因无法明确行为而导致数据发送或者接收延迟的问题；另一方面，网络设备可以将search space set的发送周期配置地大于WUS搜 索时间窗的长度，当网络设备通过group-based PDCCH发送PDCCHWUS时，能够减少下行信令开销。具体实现方案将在后文详细介绍。

作为示例而非限定，在本发明实施例中，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或智能穿戴式设备等，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、智能头盔、智能首饰等。
而如上介绍的各种终端设备，如果位于车辆上(例如放置在车辆内或安装在车辆内)，都可以认为是车载终端设备，车载终端设备例如也称为车载单元(on-board unit，OBU)。
2)、网络设备，例如包括接入网(access network，AN)设备，无线接入网(radio access network，RAN)设备，接入网设备例如基站(例如，接入点)，可以是指接入网中在空口通过一个或多个小区与无线终端设备通信的设备。基站可用于将收到的空中帧与网际协议(IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可包括IP网络。网络设备还可协调对空口的属性管理。例如，网络设备可以包括长期演进(long term evolution，LTE)系统或高级长期演进(long term evolution-advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolved Node B)，或者也可以包括第五代移动通信技术(the 5th generation，5G)新空口(new radio，NR)系统中的下一代节点B(next generation node B，gNB)或者下一代演进型基站(next generation evolved nodeB， ng-eNB)、en-gNB(enhanced next generation node B，gNB)：增强的下一代基站；也可以包括云接入网(cloud radio access network，Cloud RAN)系统中的集中式单元(centralized unit，CU)和分布式单元(distributed unit，DU)，或者还可以包括中继设备，本发明实施例并不限定。
另外在本发明实施例中，网络设备还可以包括核心网设备，核心网设备例如包括对用户的信令和数据进行处理和转发的网络设备。在4G系统中，一种核心网设备例如为移动管理实体(mobility management entity，MME)。MME是第三代合作伙伴计划(3rd generation partnership project，3GPP)协议所定义的LTE系统的接入网络的关键控制节点，它负责空闲模式的终端设备的定位和传呼过程等，包括中继。简单地说，MME是负责信令处理部分的核心网设备。或者，在5G系统中，核心网设备例如包括接入管理网元、会话管理网元或用户面网关等核心网设备。用户面网关可以是具有对用户面数据进行移动性管理、路由、转发等功能的服务器，一般位于网络侧，如服务网关(serving gateway，SGW)或分组数据网络网关(packet data network gateway，PGW)或用户面网元功能实体(user plane function，UPF)。
3)、时间窗，指一个持续的时间段，该时间段有开始时间和结束时间，时间窗的长度即为所述开始时间到结束时间的长度。例如本申请中的WUS时间窗，可以是指On Duration到来前的几个时隙。
4)、带宽部分(bandwidth part，简称BWP)：与LTE系统相比，NR系统有一个特点是网络侧和UE侧可以配置不同的带宽。UE可以根据自己的业务需求和制造成本配置自己的最大工作带宽，例如，低成本低速率UE的工作带宽可能只有5MHz，而高速率高性能UE的工作带宽可能会达到100MHz。如果小区的一个载波带宽按照低成本底速率UE设置(例如设置为5～10MHz)，那么高性能UE采用载波聚合(carrier aggregation)的方式才能获得较高的速率，这势必增加了控制信令开销和处理复杂度；如果小区的载波带宽按照高速率高性能UE来设置(例如100MHz)，那么低成本UE必须装备适合大带宽的射频和基带器件才能够接入小区，这无疑有增加了成本。因此NR引入了BWP的概念。
其中，一个BWP是一个小区载波上的一段连续频率资源，基站可以给不同的UE配置不同的带宽大小的BWP。当一个BWP被配置并且激活后，这个BWP被称为active BWP，UE上行发送的数据和控制信息或者下行接收的数据和控制信息都将限制在active BWP内。在NR Rel-15版本协议中，一个UE只能有一个active BWP。
5)、BWP切换：为使UE能够根据业务需要在不同时刻工作在不同的BWP上收发数据，NR可以支持UE进行BWP切换，即将激活的BWP从一个BWP切换为另一个BWP。
当前NR可以支持两种方式进行BWP切换：
方式一、使用在调度数据的DCI中触发UE进行BWP切换。一般情况下，调度数据的DCI可以是调度UE接收下行PDSCH数据的DCI format 1_1，也可以是调度UE发送物理上行共享信道(physical uplink shared channel，PUSCH)数据的DCI format 0_1。UE在收到上述调度DCI后，将切换到DCI指示的新的BWP上并接收或者发送数据。
方式二、基于定时器的BWP切换。当UE切换到一个BWP后，UE会启动BWP非激活定时器(BWP-inactivityTimer)，每当UE收到了一个调度(不管上行还是下行调度)，UE都会重新启动定时器。一旦BWP-inactivityTimer超时，UE将切换回默认的BWP上。
6)、灵活符号(flexible symbol)：指基站为UE配置时隙格式时，没有被指定了上行 时隙，上行符号，下行时隙或者下行符号的符号资源。基站可以通过RRC信令(如公共配置高层信令tdd-UL-DL-ConfigurationCommon或专用配置高层信令tdd-UL-DL-ConfigDedicated为UE配置一段时隙的格式，该段时隙中的一部分时隙可以被配置为上行时隙或者下行时隙，剩余的时隙中，一部分符号可以被配置为上行符号或者下行符号，而另一部分没有被配置为上行符号和下行符号的符号将被看作灵活符号。灵活符号可以根据基站的调度，灵活地用于上行数据、信令、参考信号发送，以及下行数据、控制信道和参考信号接收。
7)、本申请实施例中的术语“系统”和“网络”可被互换使用。“至少一个”是指一个或者多个，“多个”是指两个或两个以上。“和/或”，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的情况，其中A,B可以是单数或者复数。字符“/”一般表示前后关联对象是一种“或”的关系。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a,b,或c中的至少一项(个)，可以表示：a,b,c,a-b,a-c,b-c,或a-b-c，其中a,b,c可以是单个，也可以是多个。
以及，除非有相反的说明，本申请实施例提及“第一”、“第二”等序数词是用于对多个对象进行区分，不用于限定多个对象的顺序、时序、优先级或者重要程度。例如，第一优先级准则和第二优先级准则，只是为了区分不同的准则，而并不是表示这两种准则的内容、优先级或者重要程度等的不同。
此外，本申请实施例和权利要求书及附图中的术语“包括”和“具有”不是排他的。例如，包括了一系列步骤或模块的过程、方法、系统、产品或设备，不限定于已列出的步骤或模块，还可以包括没有列出的步骤或模块。
本发明实施例的技术方案可以适用于5G系统中；也可以适用于其他无线通信系统，例如长期演进(Long Term Evolution，LTE)系统，全球移动通信系统(Global System for Mobile Communication，GSM)，移动通信系统(Universal Mobile Telecommunications System，UMTS)，码分多址接入(Code Division Multiple Access，CDMA)系统，以及新的网络设备系统等。
实施例一
请参见图7，为本发明实施例中一种通信方法的流程图。该方法包括：
S101、终端设备确定第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机。
S102：终端设备在DRX状态的On Duration时间段内检测PDCCH。
其中，第一时间窗指前文所述的WUS搜索时间窗，即用于检测WUS的时间窗。WUS指前文的基于PDCCH的WUS，即用于指示终端设备在DRX状态的On Duration时间段内唤醒并检测PDCCH的信号，第一时间窗在时间上位于On Duration时间段之前。WUS可以为UE-specific PDCCH WUS，也可以为Group-based WUS，本发明实施例不做限制。
终端设备可以根据WUS搜索时间窗的结束时间、WUS搜索时间窗结束时间到DRX ON开始时间的偏移量(offset)以及WUS搜索时间窗的长度，从WUS搜索时间窗口结束时间往前确定WUS搜索时间窗的具体时间位置。
当终端设备工作在低频和高频时，终端设备判断是否要在DRX_On时间段内检测PDCCH的条件不同。
在低频情况下，也即网络设备通过一个搜索空间集合来发送WUS时，如果WUS的检测时机全部落在第一时间窗之外(也即终端设备确定第一时间窗内不存在WUS的检测时机)，如图6所示，那么终端设备在DRX_On到来时唤醒，并检测PDCCH。
在高频的情况下，也即网络设备可以通过多个搜索空间集合来发送WUS时，如果部分搜索空间集合中的WUS的检测时机落在第一时间窗之外、或者全部搜索空间集合中的WUS的检测时机落在第一时间窗之外(也即终端设备确定第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机)，那么终端设备在不连续接收DRX状态的唤醒模式On Duration到来时唤醒，并检测PSCCH。例如，参见图8所示，UE一共配置有两个(第一、第二搜索空间集合)，其中第一搜索空间集合中的WUS的检测位于WUS搜索时间窗内，第二搜索空间集合中的WUS的检测位于WUS搜索时间窗之外，则终端设备在DRX_On到来时唤醒，并检测PDCCH。
在本发明实施例中，搜索空间集合的一个发送周期的持续时间长度可以大于WUS搜索时间窗的持续时间长度。
请参见图9，为图7所示的通信方法对应在网络设备侧执行的方法的流程图。该方法包括：
S201、网络设备确定第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机。
S202、网络设备在DRX状态的On Duration时间段内发送PDCCH。
其中，网络设备确定第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机的具体实现方式，可以参照上述步骤S101中终端设备确定第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机的具体实现方式，此处不再赘述。
应理解的是，在具体实施过程中，网络设备在确定第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机后，网络设备在DRX状态的On Duration时间段内也可以不发送PDCCH。但是，对于终端设备，无论网络设备在DRX状态的On Duration时间段内是否发送了PDCCH，终端设备在DRX状态的On Duration时间段内都要唤醒检测PDCCH。
在上述方案中，当第一时间窗内不存在WUS的检测时机或者第一时间窗内不包括为终端设备配置的至少一个搜索空间集合中的WUS的检测时机时，明确了终端设备在DRX_ON到来时的行为，即使得终端设备在DRX_ON到来时唤醒并检测PDCCH。这样，一方面可以避免由于DRX_ON到来时终端设备因无法明确行为而导致数据发送或者接收延迟的问题；另一方面，网络设备可以将search space set的发送周期配置地大于WUS搜索时间窗的长度，当网络设备通过group-based PDCCH发送PDCCHWUS时，能够减少下行信令开销。
实施例二
请参见图10，为本发明实施例中另一种通信方法的流程图。该方法包括：
S301、终端设备确定第一时间窗内存在WUS的检测时机，且WUS的检测时机位于BWP切换对应的切换延迟时间内。
S302、终端设备在DRX状态的On Duration时间段内检测PDCCH。
其中，第一时间窗指前文的WUS搜索时间窗，即用于检测WUS的时间窗。WUS指前文的基于PDCCH的WUS，即用于指示终端设备在DRX状态的On Duration时间段内唤醒并检测PDCCH的信号，第一时间窗在时间上位于On Duration时间段之前。WUS可以为UE-specific PDCCH WUS，也可以为Group-based WUS，本发明实施例不做限制。
终端设备可以根据WUS搜索时间窗的结束时间、WUS搜索时间窗结束时间到DRX ON开始时间的偏移量(offset)以及WUS搜索时间窗的长度，从WUS搜索时间窗口结束时间往前确定WUS搜索时间窗的具体时间位置。
在本发明实施例中，触发终端设备进行BWP切换的原因，可以是网络设备通过调度数据的DCI触发终端设备进行BWP切换，也可以终端设备的BWP-inactivity Timer超时触发终端设备进行BWP切换，本发明实施例不做具体限制。
在本发明实施例中，终端设备在DRX状态的On Duration时间段内检测PDCCH至少包括以下两种场景：
场景1：
终端设备从第一小区的第一BWP切换到第一小区的第二BWP，第一时间窗内存在第二BWP中配置的WUS的检测时机，第二BWP中配置了DRX机制，且第二BWP中配置的WUS的检测时机位于终端设备从第一BWP切换到第二BWP时对应的切换延迟时间内，那么终端设备将在第二BWP中配置的DRX状态的On Duration时间段内检测PDCCH。
例如，请参见图11，终端设备将小区1的BWP从BWP1切换到BWP2，其中BWP2配置有DRX机制。BWP2中配置的WUS搜索时间内存在第二BWP中配置的WUS的检测时机，而BWP切换对应的切换延迟(BWP switch delay)时间和WUS搜索时间窗重叠，第二BWP中配置的WUS的检测时机落在该切换延迟时间内，虽然终端设备在WUS搜索时间窗内由于BWP切换导致射频收发功能中断，没有能力检测WUS，但是在之后的DRX_ON到来时，终端设备将唤醒并检测PDCCH。
需要说明的是，在场景1中，终端设备的服务小区可以是一个，也可以是多个(比如终端设备同时具有主服务小区和辅服务小区)，本发明实施例不做具体限制。终端设备的任意一个小区发生上述BWP切换情况时，终端设备就在该小区内执行上述步骤S301-S302的方法步骤。
场景2：
终端设备从第一小区的第一BWP切换至所述第一小区的第二BWP，第一时间窗内存在第二小区的BWP中配置的唤醒信号的检测时机，第二小区的BWP中配置的唤醒信号的检测时机位于终端设备从第一BWP切换到第二BWP时对应的切换延迟时间内，那么终端设备将在第二小区的BWP中配置的DRX状态的On Duration时间段内检测PDCCH。
例如，请参见图12，终端设备的小区1配置有BWP1和BWP2，终端设备将小区1的BWP从BWP1切换到BWP2。终端设备的小区2配置有BWP3，且BWP3配置了DRX机制，BWP3中配置的WUS搜索时间内存在WUS的检测时机，而BWP切换对应的切换延迟(BWP switch delay)时间和该WUS搜索时间窗重叠，且BWP3中配置的WUS的检测时机刚好落在该切换延迟时间内，在这种情况下，如果小区1和小区2使用的是同一射频链路，那么小区2在WUS搜索时间窗内射频收发功能中断，没有能力检测区WUS，但是在DRX_ON到来时，终端设备将唤醒并在小区2的BWP3中检测PDCCH。
需要说明的是，场景2中，终端设备的服务小区的数量不限于以上举例中的两个，但 是，只要是共用同一射频链路的多个小区中的一个小区如上述第一小区发生BWP切换时，该多个小区中的其它小区均可以执行上述第二小区所执行的方法。
请参见图13，为图10所示的通信方法对应在网络设备侧执行的方法的流程图。该方法包括：
S401、网络设备确定第一时间窗内存在WUS的检测时机，且WUS的检测时机位于BWP切换对应的切换延迟时间内。
S402、网络设备在DRX状态的On Duration时间段内发送PDCCH。
网络设备确定第一时间窗内存在WUS的检测时机且WUS的检测时机位于BWP切换对应的切换延迟时间内的具体实现方式，可以参照上述步骤S301中终端设备第一时间窗内存在WUS的检测时机且WUS的检测时机位于BWP切换对应的切换延迟时间内的具体实现方式，此处不再赘述。
应理解的是，在具体实施过程中，网络设备在确定第一时间窗内存在WUS的检测时机，且WUS的检测时机位于BWP切换对应的切换延迟时间内后，网络设备在DRX状态的On Duration时间段内也可以不发送PDCCH。但是对于终端设备，无论网络设备在DRX状态的On Duration时间段内是否发送了PDCCH，终端设备在DRX状态的On Duration时间段内都要唤醒检测PDCCH。
在上述方案中，当终端设备由于发生BWP切换原因无法检测WUS时，明确了终端设备在DRX_ON到来时的行为，即使得终端设备在DRX_ON到来时唤醒并检测PDCCH。这样，可以避免由于DRX_ON到来时终端设备因无法明确行为而导致数据发送或者接收延迟的问题。
实施例三
请参见图22，为本发明实施例中另一种通信方法的流程图。该方法包括：
S1301、终端设备确定第一时间窗内存在唤醒信号的检测时机，且所述唤醒信号的检测时机位与flexible symbols所在的时域资源部分或全部重合。
示例性地，用于发送WUS的search space set的部分或者全部符号位于flexible symbol之内；或者flexible symbol的部分或者全部符号位于WUS检测时机内，本发明实施例不做具体限制。
在本发明实施例中，所述flexible symbol可以是网络设备通过公共配置高层信令tdd-UL-DL-ConfigurationCommon或专用配置高层信令tdd-UL-DL-ConfigurationDedicated配置的flexible symbol，本发明实施例不做具体限制。flexible symbol的量化单位可以是帧、子帧、时隙或符号等时间单位，本发明实施例不做具体限制。可选的，网络设备可以是通过DCI format 2_0动态指示的flexible symbol。
S1302、终端设备在DRX状态的On Duration时间段内检测PDCCH。
其中，第一时间窗指前文的WUS搜索时间窗，即用于检测WUS的时间窗。WUS指前文的基于PDCCH的WUS，即用于指示终端设备在DRX状态的On Duration时间段内唤醒并检测PDCCH的信号，第一时间窗在时间上位于On Duration时间段之前。WUS可以为UE-specific PDCCH WUS，也可以为Group-based WUS，本发明实施例不做限制。
终端设备可以根据WUS搜索时间窗的结束时间、WUS搜索时间窗结束时间到DRX ON开始时间的偏移量(offset)以及WUS搜索时间窗的长度，从WUS搜索时间窗口结束时间往前确定WUS搜索时间窗的具体时间位置。
请参见图23，为图22所示的通信方法对应在网络设备侧执行的方法的流程图。该方法包括：
S1401、网络设备确定第一时间窗内存在唤醒信号的检测时机，且所述唤醒信号的检测时机位与flexible symbols所在的时域资源部分或全部重合。
网络设备确定第一时间窗内存在WUS的检测时机且WUS的检测时机与flexible symbol的时间频域区域重合的具体实现方式，可以参照上述步骤S301中终端设备第一时间窗内存在WUS的检测时机且WUS的检测时机与flexible symbol的时间频域区域重合的具体实现方式，此处不再赘述。
S1402、网络设备在DRX状态的On Duration时间段内发送PDCCH。
应理解的是，在具体实施过程中，网络设备在确定第一时间窗内存在WUS的检测时机，且WUS的检测时机位与flexible symbol的时间频域区域重合后，网络设备在DRX状态的On Duration时间段内也可以不发送PDCCH。但是对于终端设备，无论网络设备在DRX状态的On Duration时间段内是否发送了PDCCH，终端设备在DRX状态的On Duration时间段内都要唤醒检测PDCCH。
在上述方案中，当终端设备由于唤醒信号的检测时机和flexible symbol的时域资源重合时，明确了flexible symbol不能被WUS占用而固定为下行符号，同时明确了UE在唤醒信号的检测时机和flexible symbol的时频区域重合后的On Duration上的行为，即使得终端设备在flexible symbol后的On Duration到来时唤醒并检测PDCCH。这样，可以保持flexible symbol可以用于上下行的灵活特性，避免由于On Duration到来时终端设备因无法明确行为而导致数据发送或者接收延迟的问题。
