Description

通信方法、设备及系统 技术领域
本申请涉及通信技术领域，尤其涉及通信方法、设备及系统。
背景技术
在无线通信系统中，终端设备有两种状态，一种是连接态，表示终端设备已与网络设备建立了连接，可直接进行通信；一种是空闲态或称为睡眠态，表示终端设备无法与网络设备直接进行通信。终端设备在没有业务数据发送或者接收时，可以进入空闲态以降低耗电量。当网络设备要向终端设备发送业务数据或者需要终端设备上报一些业务数据时，可以通过寻呼机制通知终端设备，而空闲态的终端设备会定期醒来监听物理下行控制信道(physical downlink control channel，PDCCH)，检测PDCCH中是否存在寻呼调度消息，若存在寻呼调度消息，且是针对自己的寻呼调度，则空闲态的终端设备切换到连接态，以便发送或者接收业务数据。其中，终端设备醒来的位置称为寻呼机会(paging occasion，PO)。
然而，目前的物联网中，有很多业务是主动上报的类型，即以上行为主，寻呼概率较低，因此网络设备在大部分以PO对应的子帧为起始子帧的PDCCH搜索空间中不发送相应的寻呼调度消息，但是终端设备依然需要从该终端设备对应的每个PO处开始监听PDCCH。其中，在以每个PO对应的子帧为起始子帧的PDCCH搜索空间中，终端设备从PDCCH搜索空间的第一个备选位置开始盲检完所有的备选位置才确定没有寻呼调度消息，这对终端设备来说是一种功耗浪费。
基于此，现有技术中，网络设备可以在PO前向终端设备发射唤醒信号(wakeup signal，WUS)，该WUS用于指示终端设备需要监听PDCCH。当终端设备在PO前检测到WUS，则需要继续监听PDCCH；若终端设备在PO前未检测到WUS，终端设备可以不监听该PDCCH，从而可以节省终端设备的功耗。
然而，目前WUS的发送时间内，基站在相应的物理资源块(physical resource block，PRB)上都不能进行下行数据或者下行信道的传输，因此将造成整个下行信道阻塞，从而影响基站的调度。
发明内容
本申请实施例提供通信方法、设备及系统，用于解决目前唤醒信号的发送时间内，下行信号阻塞，从而影响基站的调度的问题。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种通信方法，该方法包括：确定第一资源，该第一资源为下行传输间隔资源；若该第一资源与第二资源在时域上重叠，在第三资源上接收唤醒信号，其中，该第二资源为根据该唤醒信号的最大持续时间确定的用于传输该唤醒信号的资源；该第三资源包括该第二资源中除与该第一资源在时域上重叠部分之外的部分或全部资源。换言之，第三资源包括第二资源的部分资源，第三资源与第一资源在时域上不重叠。基于该通信方法，由于本申请实施例中，若用于传输唤醒信号的第二资 源与下行传输间隔资源在时域上重叠，则在第二资源中除与第一资源在时域上重叠部分之外的部分或全部资源上接收唤醒信号，不在第一资源与第二资源在时域上重叠部分接收唤醒信号，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行信道拥塞，降低对基站调度的影响。
在一种可能的设计中，若该第一资源与第二资源在时域上重叠，在第三资源上接收唤醒信号，包括：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若该第一资源与该第二资源在时域上重叠，在该第三资源上接收该唤醒信号，P和Q均为正整数。示例性的，P和Q取值可以均为1。也就是说，本申请实施例中，在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，才进一步确定第一资源与第二资源是否在时域上重叠；否则，在(P×唤醒信号的最大持续时间)小于(Q×第一阈值)的情况下，认为唤醒信号传输中没有第一资源。
第二方面，提供了一种通信方法，该方法包括：确定第一资源，该第一资源为下行传输间隔资源；若该第一资源与第二资源在时域上重叠，在第三资源上发送唤醒信号，其中，该第二资源为根据该唤醒信号的最大持续时间确定的用于传输该唤醒信号的资源；该第三资源包括该第二资源中除与该第一资源在时域上重叠部分之外的部分或全部资源。基于该通信方法，由于本申请实施例中，若用于传输唤醒信号的第二资源与下行传输间隔资源在时域上重叠，则在第二资源中除与第一资源在时域上重叠部分之外的部分或全部资源上接收唤醒信号，不在第一资源与第二资源在时域上重叠部分接收唤醒信号，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行信道拥塞，降低对基站调度的影响。
在一种可能的设计中，若该第一资源与第二资源在时域上重叠，在第三资源上发送该唤醒信号，包括：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若该第一资源与该第二资源在时域上重叠，在该第三资源上发送该唤醒信号，P和Q均为正整数。示例性的，P和Q取值可以均为1。也就是说，本申请实施例中，在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，才进一步确定第一资源与第二资源是否在时域上重叠；否则，在(P×唤醒信号的最大持续时间)小于(Q×第一阈值)的情况下，认为唤醒信号传输中没有第一资源。
结合上述第一方面或第二方面，在一种可能的设计中，该第一资源与该第二资源在时域上重叠部分的第一个子帧为该第二资源的第x1个目标子帧，该第一资源与该第二资源在时域上重叠部分的最后一个子帧为该第二资源的第y1个目标子帧，x1为小于或者等于N的正整数，y1为小于N的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧，N为实际用于映射该唤醒信号的序列的目标子帧的个数；其中，该第三资源包括：该第x1个目标子帧之前的(x1-1)个目标子帧、以及该第y1个目标子帧之后的(N-y1)个目标子帧。也就是说，第二资源上的第x1个目标子帧至第y1个目标子帧上的唤醒信号被丢弃(drop)。需要说明的是，本申请实施例中，被丢弃(drop)可以理解为，第二资源上的第x1个目标子帧至第y1个目标子帧还用于映射唤醒信号的序列，但是不用于传输唤醒信号。
结合上述第一方面或第二方面，在一种可能的设计中，该第一资源与该第二资源在时域上重叠部分的第一个子帧为该第二资源的第x2个目标子帧，该第一资源与该第 二资源在时域上重叠部分的最后一个子帧为该第二资源的第y2个目标子帧，x2为小于或者等于N的正整数，y2为大于或者等于N的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧，N为实际用于映射该唤醒信号的序列的目标子帧的个数；其中，该第三资源包括：第x2个目标子帧之前的(x2-1)个目标子帧。也就是说，第二资源上的第x2个目标子帧至第N个目标子帧上的唤醒信号被丢弃(drop)。需要说明的是，本申请实施例中，被丢弃(drop)可以理解为，第二资源上的第x2个目标子帧至第N个目标子帧还用于映射唤醒信号的序列，但是不用于传输唤醒信号。
结合上述第一方面或第二方面，在一种可能的设计中，N个映射唤醒信号的序列的目标子帧包括第二资源的第一个子帧至第二资源的第N个子帧。
结合上述第一方面或第二方面，在一种可能的设计中，该第一资源与该第二资源在时域上重叠部分的第一个子帧为该第二资源的第x3个目标子帧，该第一资源与该第二资源在时域上重叠部分的最后一个子帧为该第二资源的第y3个目标子帧，x3为小于或者等于N的正整数，y3为小于或者等于M的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧；N为实际用于映射该唤醒信号的序列的目标子帧的个数，M为该唤醒信号的最大持续时间内目标子帧的个数；其中，该第三资源包括：该第x3个该目标子帧之前的S1个目标子帧，以及第y3个目标子帧之后的S2个目标子帧，其中，S1为整数，S2为整数，S1+S2≤N。可以理解，第x3个目标子帧至第N个目标子帧上的唤醒信号的序列被映射到第(y3+1)个目标子帧至第(y3+S2)个目标子帧上，这也就意味着，第x3个目标子帧至第N个目标子帧上的唤醒信号被延迟发送(postpone)。需要说明的是，本申请实施例中，唤醒信号被延迟发送(postpone)可以理解为，第一资源和第二资源的时域重叠资源上的唤醒信号，以及重叠资源之后资源上的唤醒信号均被延迟发送，即假设没有第一资源时唤醒信号原本在目标子帧Z上发送，则当有第一资源，且第一资源是目标子帧Z时，唤醒信号在目标子帧Z+1发送，然后在后续的目标子帧上继续发送唤醒信号。
结合上述第一方面或第二方面，在一种可能的设计中，该第三资源的时域起始位置相对于该第一资源或者该第二资源的时域起始位置提前K个目标子帧，其中，K为该第一资源和该第二资源的时域重叠部分的子帧的个数，K为正整数。基于该方案，可以保证唤醒信号被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置不会超出第二资源的结束位置，从而可以避免当唤醒信号被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个唤醒信号资源处，或者可能与唤醒信号资源和PO之间的gap重叠，或者可能与PO重叠的问题。
第三方面，提供了一种通信方法，该方法包括：确定第一资源，第一资源为下行传输间隔资源；若第一资源与第四资源在时域上重叠，在第三资源上接收唤醒信号；其中，第四资源为持续时间小于或者等于该唤醒信号的最大持续时间的唤醒信号资源，该第三资源与第一资源在时域上不重叠。基于该通信方法，由于本申请实施例中，若第一资源与第四资源在时域上重叠，则在与第一资源在时域上不重叠的第三资源上接收唤醒信号，不在第一资源与第四资源的重叠部分接收唤醒信号，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行 信道拥塞，降低对基站调度的影响。
在一种可能的设计中，若第一资源与第四资源在时域上重叠，在第三资源上接收唤醒信号，包括：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，在该第三资源上接收该唤醒信号，P和Q均为正整数。示例性的，P和Q取值可以均为1。也就是说，本申请实施例中，在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，才进一步确定第一资源与第四资源是否在时域上重叠；否则，在(P×唤醒信号的最大持续时间)小于(Q×第一阈值)的情况下，认为唤醒信号传输中没有第一资源。也就是说，本申请实施例中，在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，才进一步确定第一资源与第四资源是否在时域上重叠；否则，在(P×唤醒信号的最大持续时间)小于(Q×第一阈值)的情况下，认为唤醒信号传输中没有第一资源。
第四方面，提供了一种通信方法，该方法包括：确定第一资源，第一资源为下行传输间隔资源；若第一资源与第四资源在时域上重叠，在第三资源上发送唤醒信号；其中，第四资源为持续时间小于或者等于该唤醒信号的最大持续时间的唤醒信号资源，该第三资源与第一资源在时域上不重叠。基于该通信方法，由于本申请实施例中，若第一资源与第四资源在时域上重叠，则在与第一资源在时域上不重叠的第三资源上发送唤醒信号，不在第一资源与第四资源的重叠部分发送唤醒信号，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行信道拥塞，降低对基站调度的影响。
在一种可能的设计中，若第一资源与第四资源在时域上重叠，在第三资源上发送唤醒信号，包括：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，在该第三资源上发送该唤醒信号，P和Q均为正整数。示例性的，P和Q取值可以均为1。也就是说，本申请实施例中，在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，才进一步确定第一资源与第四资源是否在时域上重叠；否则，在(P×唤醒信号的最大持续时间)小于(Q×第一阈值)的情况下，认为唤醒信号传输中没有第一资源。
结合上述第三方面或第四方面，在一种可能的设计中，第一资源和第四资源的时域重叠资源上的唤醒信号被丢弃。
示例性的，该第一资源与该第四资源在时域上重叠部分的第一个子帧为该第四资源的第x1个目标子帧，该第一资源与该第四资源在时域上重叠部分的最后一个子帧为该第四资源的第y1个目标子帧，x1为小于或者等于N的正整数，y1为小于N的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧，N为实际用于映射该唤醒信号的序列的目标子帧的个数；其中，该第三资源包括：第四资源上的第x1个目标子帧之前的(x1-1)个目标子帧、以及第y1个目标子帧之后的(N-y1)个目标子帧。也就是说，第四资源上的第x1个目标子帧至第y1个目标子帧上的唤醒信号被丢弃(drop)。需要说明的是，本申请实施例中，被丢弃(drop)可以理解为，第四资源上的第x1个目标子帧至第y1个目标子帧还用于映射唤醒信号的序列，但是不用于传输唤醒信号。
示例性的，该第一资源与该第四资源在时域上重叠部分的第一个子帧为该第二资源的第x2个目标子帧，该第一资源与该第二资源在时域上重叠部分的最后一个子帧为 该第四资源的第N个目标子帧，x2为小于或者等于N的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧，N为实际用于映射该唤醒信号的序列的目标子帧的个数；其中，该第三资源包括：第四资源上的第x2个目标子帧之前的(x2-1)个目标子帧。也就是说，第四资源上的第x2个目标子帧至第N个目标子帧上的唤醒信号被丢弃(drop)。需要说明的是，本申请实施例中，被丢弃(drop)可以理解为，第四资源上的第x2个目标子帧至第N个目标子帧还用于映射唤醒信号的序列，但是不用于传输唤醒信号。
可选的，N个用于映射唤醒信号的序列的目标子帧包括第四资源的第一个子帧至所述第四资源的第N个子帧。
结合上述第三方面或第四方面，在一种可能的设计中，第一资源与第二资源的时域重叠资源上的唤醒信号被延迟发送。
示例性的，该第一资源与第四资源在时域上重叠部分的第一个子帧为该第二资源的第x3个目标子帧，该第一资源与该第二资源在时域上重叠部分的最后一个子帧为该第二资源的第y3个目标子帧，x3为小于或者等于N的正整数，y3为小于或者等于N的正整数，该目标子帧为可用于映射该唤醒信号的序列的子帧，N为实际用于映射该唤醒信号的序列的目标子帧的个数；其中，该第三资源包括：该第x3个该目标子帧之前的S1个目标子帧，以及第y3个目标子帧之后的S2个目标子帧，其中，S1为整数，S2为整数，S1+S2≤N。可以理解，第x3个目标子帧至第N个目标子帧上的唤醒信号的序列被映射到第(y3+1)个目标子帧至第(y3+S2)个目标子帧上，这也就意味着，第x3个目标子帧至第N个目标子帧上的唤醒信号被延迟发送(postpone)。需要说明的是，本申请实施例中，唤醒信号被延迟发送(postpone)可以理解为，第一资源和第二资源的时域重叠资源上的唤醒信号，以及重叠资源之后资源上的唤醒信号均被延迟发送，即假设没有第一资源时唤醒信号原本在目标子帧Z上发送，则当有第一资源，且第一资源是目标子帧Z时，唤醒信号在目标子帧Z+1发送，然后在后续的目标子帧上继续发送唤醒信号。
结合上述第三方面或第四方面，在一种可能的设计中，子帧k之后的唤醒信号被丢弃，其中，子帧k为第二资源的结束子帧，第二资源为根据该唤醒信号的最大持续时间确定的用于传输该唤醒信号的资源。基于该方案，可以避免当唤醒信号被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个唤醒信号资源处，或者可能与唤醒信号资源和PO之间的gap重叠，或者可能与PO重叠的问题。
结合上述第三方面或第四方面，在一种可能的设计中，该第三资源的时域起始位置相对于第四资源或者第一资源的时域起始位置提前K个目标子帧，其中，K为该第一资源和第二资源的时域重叠部分的目标子帧的个数，K为正整数，第二资源为根据该唤醒信号的最大持续时间确定的用于传输该唤醒信号的资源。基于该方案，可以保证唤醒信号被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置不会超出第二资源的结束位置，从而可以避免当唤醒信号被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个唤醒信号资源处，或者可能与唤醒信号资源和PO之间的gap 重叠，或者可能与PO重叠的问题，其中，第二资源为根据该唤醒信号的最大持续时间确定的用于传输该唤醒信号的资源。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术和术语的简要介绍如下。
第一，物联网(internet of things，IoT)：
IoT是“物物相连的互联网”。它将互联网的用户端扩展到了任何物品与物品之间，使得在任何物品与物品之间可以进行信息交换和通信。这样的通信方式也称为机器间通信(machine type communications，MTC)。其中，通信的节点称为MTC终端或MTC设备。典型的IoT应用包括智能电网、智能农业、智能交通、智能家居以及环境检测等各个方面。
由于物联网需要应用在多种场景中，比如从室外到室内，从地上到地下，因而对物联网的设计提出了很多特殊的要求。比如，由于某些场景下的MTC终端应用在覆盖较差的环境下，如电表水表等通常安装在室内甚至地下室等无线网络信号很差的地方，因此需要覆盖增强的技术来解决。或者，由于某些场景下的MTC终端的数量要远远大于人与人通信的设备数量，也就是说需要大规模部署，因此要求能够以非常低的成本获得并使用MTC终端。或者，由于某些场景下的MTC终端传输的数据包很小，并且对延时并不敏感，因此要求支持低速率的MTC终端。或者，由于在大多数情况下，MTC终端是通过电池来供电的，但是同时在很多场景下，MTC终端又要求能够使用十年以上而不需要更换电池，这就要求MTC终端能够以极低的电力消耗来工作。
为了满足上述需求，移动通信标准化组织第三代合作伙伴计划(3rd generation partnership project，3GPP)在无线接入网络(radio access network，RAN)#62次全会上通过了一个新的研究课题来研究在蜂窝网络中支持极低复杂度和低成本的物联网的方法，并且在RAN#69次会议上立项为窄带物联网(narrow band internet of thing，
NB-IoT)课题。其中，NB-IoT的带宽为180kHz，即为一个PRB。
第二，WUS：
如图1a所示，3GPP版本(release，Rel)15中，WUS的最大持续时间(maximum WUS duration)为L NWUSmax。WUS和对应的PO之间存在一个间隔(gap)，该gap的作用主要是留给终端设备一段时间醒来在PO处去盲检PDCCH。其中，该gap可以为非连续接收(discontinuous reception，DRX)的gap、扩展DRX(extended DRX,eDRX)的短gap和eDRX的长gap，在此不做具体限定。
终端设备在WUS资源上检测是否存在WUS，若终端设备检测到WUS，表示基站可能在寻呼该终端设备，则该终端设备会在PO处开始监听PDCCH；若终端设备未检测到WUS，表示基站没有在寻呼该终端设备，则该终端设备进入睡眠状态，从而可以节省终端设备的功耗。其中，WUS的发送都是从WUS资源的起始时刻开始。WUS的实际持续时间(WUS actual duration)可以是2的指数倍个子帧，比如1、2、4、8、……、L NWUSmax，如表一所示。
表一
L NWUSmax 实际WUS持续时间集合(actual WUS duration set)
1 {1}
2 {1，2}
4 {1，2，4}
8 {1，2，4，8}
16 {1，2，4，8，16}
32 {1，2，4，8，16，32}
64 {1，2，4，8，16，32，64}
128 {1，2，4，8，16，32，64，128}
256 {1，2，4，8，16，32，64，128，256}
512 {1，2，4，8，16，32，64，128，256，512}
1024 {1，2，4，8，16，32，64，128，256，512，1024}
然而，由于图1a中PO处的所有终端设备都需要检测WUS，然后根据是否检测到WUS，再继续在PO处去盲检PDCCH。因此若基站想寻呼终端设备A而发了WUS，但是终端设备B也检测到了WUS从而醒来，可能造成终端设备B错误的被唤醒(false wake up)，从而会影响终端设备B的功耗。基于此，3GPP Rel16中引入了对PO处的终端设备的分组处理，不同的分组对应不同的WUS。例如，可以将PO处的终端设备分成两组，包括组A(group A)和组B(group B)。group A对应WUS1(也可以称为group WUS 1)，WUS1用于指示PO上的group A中的终端设备监测PDCCH进而去接收寻呼消息；group B对应WUS 2(也可以称为group WUS 2)，WUS2用于指示PO上的group B中的终端设备监测PDCCH进而去接收寻呼消息，这样就可以降低终端设备被错误唤醒的概率，从而节省终端设备的功耗。
同时，3GPP Rel-16中还引入了一种公共(common)WUS，该公共WUS用于唤醒PO处所有分组的终端设备。例如，WUS 3即为common WUS，用于唤醒PO处的所有组的终端设备。
需要说明的是，本申请实施例中的WUS资源可以为传统WUS资源(legacy WUS resource)(可以理解为Rel-15的WUS资源，即图1a中的WUS资源)或者上述group WUS资源(可以理解group WUS资源可以是Rel-15的WUS资源，即图1b中的第一个WUS资源，也可以是Rel-16的WUS资源，即图1b中的第二个WUS资源)，本申请实施例对此不作具体限定。
需要说明的是，在图1b中的第一个WUS资源，即Rel-15的WUS资源上，可以发送WUS或者group WUS或者common WUS，在此统一说明，以下不再赘述。
需要说明的是，本申请实施例中，WUS的最大持续时间可以理解为表一中的L NWUSmax，或者为最大用于映射WUS的序列的目标子帧的个数，WUS的实际持续时间可以理解为实际发送的WUS的长度，或者实际用于映射WUS的序列的目标子帧的个数。比如，若WUS的最大持续时间＝1024，WUS的实际持续时间为512，则可以理解为最大用于映射WUS的序列的目标子帧的个数为1024，实际用于映射WUS的序列的目标子帧的个数为512。这里的目标子帧为可用于映射WUS的序列的子帧，包括有效子帧和传输系统信息块(system information block，SIB)1的子帧4，其中，传输SIB1的子帧4不是有效子帧。有效子帧是指满足一定条件的子帧，该一定条件例如可以包括条件1和条件2，条件1为该子帧上不用于发送窄带主同步信号(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)和SIB1-NB；条件2为该子帧被配置成有效子帧，相关定义可参考现有技术，在此不再赘述。此外，本申请实施例中，用于映射唤醒信号的序列的子帧可以为连续的，也可以为不连续的，本申请实施例对此不作具体限定。
第三，第一资源、第二资源和第三资源：
本申请实施例中的第一资源为下行(downlink，DL)传输间隔(transmission gap)资源。
本申请实施例中的第二资源为根据唤醒信号的最大持续时间确定的用于传输唤醒信号的资源，如图1a中持续时间为L NWUSmax的WUS资源。可以理解，本申请实施例中的第二资源上的子帧均为上述定义的目标子帧，换言之，第二资源上的“第xxx个子帧”与第二资源上的“第xxx个目标子帧”是同一个概念，可以相互替换，在此统一说明，以下不再赘述。
本申请实施例中的第三资源包括第二资源中除与第一资源在时域上重叠部分之外的部分或全部资源，换言之，第三资源包括第二资源的部分资源，第三资源与第一资源在时域上不重叠。
其中，第一资源、第二资源和第三资源的相对位置将在后续方法实施例中详细阐述，在此不予赘述。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“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，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“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。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请 实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
本申请实施例可以适用于长期演进(long term LTE)系统(如上述的NB-IOT系统)或NR系统(也可以称之为第五代(5th generation，5G)系统)，也可以适用于其他面向未来的新系统等，本申请实施例对此不作具体限定。此外，术语“系统”可以和“网络”相互替换。
如图2所示，为本申请实施例提供的一种通信系统20，该通信系统20包括一个第二通信装置30(图2示例性的以第二通信装置为网络设备为例进行说明)以及与第二通信30连接的一个或多个第一通信装置40(图2示例性的以第一通信装置为终端设备为例进行说明)。以任意一个第一通信装置40与第二通信装置30通信为例，则第二通信装置30，用于确定第一资源；第二通信装置30，还用于若第一资源与第二资源在时域上重叠，在第三资源上向第一通信装置40发送唤醒信号。第一通信装置40，用于确定第一资源；第一通信装置40，还用于若第一资源与第二资源在时域上重叠，在第三资源上接收来自第二通信装置30的唤醒信号，其中，第一资源、第二资源和第三资源的相关定义可参考上述相关技术及术语介绍的第三点，在此不再赘述。该方案的具体实现将在后续方法实施例中详细阐述，在此不予赘述。基于该通信系统，由于本申请实施例中，若用于传输唤醒信号的第二资源与下行传输间隔资源在时域上重叠，则在第二资源中除与第一资源在时域上重叠部分之外的部分或全部资源上接收或发送唤醒信号，不在第一资源与第二资源在时域上重叠部分接收或发送唤醒信号，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行信道拥塞，降低对第二通信装置(如基站)调度的影响。
可选的，本申请实施例中的第二通信装置可以为网络设备或者其他用于发送唤醒信号的通信装置，本申请实施例中的第一通信装置可以为终端设备或者其他用于接收唤醒信号的通信装置，本申请实施例对此不作具体限定。
可选的，本申请实施例中的终端设备，可以是用于实现无线通信功能的设备，例如终端或者可用于终端中的芯片等。其中，终端可以是5G网络或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、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)、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、车载设备或可穿戴设备，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、远程医疗(remote medical)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。终端可以是移动的，也可以是固定的。
可选的，本申请实施例中的网络设备可以是能和终端设备通信的设备。该网络设备可以包括传输接收点(transmission reception point，TRP)、基站、分离式基站的远端射频单元(remote radio unit，RRU)或基带单元(baseband unit，BBU)(也可称为数字单元(digital unit，DU))、宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机、非3GPP接入设备、中继站或接入点等。其中，图2中以网络设备为基站为例进行示意，在此统一说明，以下不再赘述。此外，本申请实施例中的基站可以是全球移动通信系统(global system for mobile communication，GSM)或码分多址(code division multiple access，CDMA)网络中的基站收发信台(base transceiver station，BTS)、宽带码分多址(wideband code division multiple access，WCDMA)中的NB(NodeB)、LTE中的eNB或eNodeB(evolutional NodeB)、云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器或者5G通信系统中的基站、或者未来演进网络中的基站等，在此不作具体限定。
可选的，本申请实施例中的第二通信装置30与第一通信装置40也可以称之为通信设备，其可以是一个通用设备或者是一个专用设备，本申请实施例对此不作具体限定。
本申请实施例中的第二通信装置30与第一通信装置40的相关功能可以由一个设备实现，也可以由多个设备共同实现，还可以是由一个设备内的一个或多个功能模块实现，本申请实施例对此不作具体限定。可以理解的是，上述功能既可以是硬件设备中的网络元件，也可以是在专用硬件上运行的软件功能，或者是硬件与软件的结合，或者是平台(例如，云平台)上实例化的虚拟化功能。

在一些实施例中，图3中的通信接口304的功能可以通过图4中的天线1，天线2，移动通信模块150，无线通信模块160等实现。
其中，天线1和天线2用于发射和接收电磁波信号。终端设备中的每个天线可用于覆盖单个或多个通信频带。不同的天线还可以复用，以提高天线的利用率。例如：可以将天线1复用为无线局域网的分集天线。在另外一些实施例中，天线可以和调谐开关结合使用。

在一些实施例中，终端设备的天线1和移动通信模块150耦合，天线2和无线通信模块160耦合，使得终端设备可以通过无线通信技术与网络以及其他设备通信。

可以理解的是，图4所示的结构并不构成对终端设备的具体限定。比如，在本申请另一些实施例中，终端设备可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。

其中，该基站包括一个或多个射频单元(如RRU501)、以及一个或多个BBU(也可称为数字单元(digital unit，简称DU))502。
RRU501可以称为收发单元、收发机、收发电路、或者收发器等等，其可以包括至少一个天馈系统(即天线)511和射频单元512。该RRU501主要用于射频信号的收发以及射频信号与基带信号的转换。在一些实施例中，图3中的通信接口304的功能可以通过图5中的RRU501实现。
该BBU502为网络设备的控制中心，也可以称为处理单元，主要用于完成基带处理功能，如信道编码，复用，调制，扩频等等。
在一些实施例中，该BBU502可以由一个或多个单板构成，多个单板可以共同支持单一接入指示的无线接入网(如LTE网络)，也可以分别支持不同接入制式的无线接入网(如LTE网络，5G网络或其它网络)。该BBU502还可以包括存储器521和处理器522，该存储器521用于存储必要的指令和数据。该处理器522用于控制网络设备进行必要的动作。该存储器521和处理器522可以服务于一个或多个单板。也就是说，可以每个单板上单独设置存储器和处理器。也可以是多个单板共用相同的存储器和处理器。此外每个单板上还可以设置有必要的电路。其中，在一些实施例中，图3中的处理器301的功能可以通过图5中的处理器522实现，图3中的存储器303的 功能可以通过图5中的存储器521实现。
可选的，图5中的RRU501与BBU502可以是物理上设置在一起，也可以物理上分离设置的，例如，分布式基站，本申请实施例对此不作具体限定。
下面将结合图1a至图5，对本申请实施例提供的通信方法进行详细阐述。
如图6所示，为本申请实施例提供的一种通信方法，该通信方法以图2所示的通信系统为例进行说明，即假设第一通信装置为终端设备，第二通信装置为网络设备，则本申请实施例提供的通信方法包括如下步骤：
S601、网络设备确定第一资源。
可选的，本申请实施例中，网络设备可以确定下行传输间隔资源(即第一资源)的配置，该下行传输间隔资源的配置包括周期(可以记为N gap,period)，持续时间比例因子(可以记为N gap,coeff)和第一阈值。其中，下行传输间隔资源的起始时域位置满足公式

Figure PCTCN2019109767-appb-000002
表示向下取整，mod表示取余。持续时间(N gap,duration)满足N gap,duration＝N gap,coeffN gap,period，单位为子帧。
可选的，本申请实施例中的第一阈值可以是现有协议中的阈值N gap,threshold，也可以是基站配置的另外一个阈值(可以记为N gap,threshold,WUS)，比如基站通过系统消息配置N gap,threshold,WUS，本申请实施例对此不作具体限定。示例性的，N gap,threshold,WUS的取值范围例如可以为16，32，64或者128等。
S602、终端设备确定第一资源。
可选的，本申请实施例中，网络设备可以将下行传输间隔资源的配置发送给终端设备，进而终端设备可以根据下行传输间隔资源的配置确定下行传输间隔资源。其中，下行传输间隔资源的配置的相关描述可参考上述步骤S601，在此不再赘述。
S603、若第一资源与第二资源在时域上重叠，网络设备在第三资源上向终端设备发送WUS。相应的，终端设备在第三资源上接收来自网络设备的WUS。
可选的，本申请实施例中，若第一资源与第二资源在时域上重叠，网络设备在第三资源上向终端设备发送WUS，包括：在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第二资源在时域上重叠，网络设备在第三资源上向终端设备发送WUS，P和Q均为正整数。也就是说，本申请实施例中，在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，网络设备才进一步确定第一资源与第二资源是否在时域上重叠；否则，在(P×WUS的最大持续时间)小于(Q×第一阈值)的情况下，网络设备认为WUS传输中没有第一资源。
可选的，本申请实施例中，若第一资源与第二资源在时域上重叠，终端设备在第三资源上接收来自网络设备的WUS，包括：在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第二资源在时域上重叠，终端设备在第三资源上接收来自网络设备的WUS，P和Q均为正整数。也就是说，本申请实施例中，在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，终端设备才进一步确定第一资源与第二资源是否在时域上重叠，否则，在(P×WUS的最大持续时间)小于(Q×第一阈值)的情况下，终端设备认为WUS传输中没有第一资源。
示例性的，这里P和Q的取值可以均为1；或者，P的取值为1，Q的取值为大于1的正整数；或者，Q的取值为1，P的取值为大于1的正整数。
当然，在步骤S603中，终端设备或网络设备还可以通过比较第一类(type-1)公共搜索空间(common search space，CSS)的长度(R max)与第一阈值来确定对于WUS，是否存在下行传输间隔资源，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中的“不小于”可以理解为“大于或者等于”，在此统一说明，以下不再赘述。
下面给出第一资源、第二资源和第三资源的相对位置的具体描述。
场景一：N个用于映射WUS的序列的目标子帧包括第二资源的第一个子帧至第二资源的第N个子帧。也可以理解为，WUS的序列被映射到第二资源的第一个子帧至第二资源的第N个子帧上。
需要说明的是，本申请实施例中的“第几个”可以理解为是从“第一个”开始连续计数的，在此统一说明，以下不再赘述。
一种可能的实现方式中，第一资源与第二资源在时域上重叠部分的第一个子帧为第二资源的第x1个目标子帧，第一资源与第二资源在时域上重叠部分的最后一个子帧为第二资源的第y1个目标子帧，x1为小于或者等于N的正整数，y1为小于N的正整数。第三资源包括：第x1个目标子帧之前的(x1-1)个目标子帧、以及第y1个目标子帧之后的(N-y1)个目标子帧。
需要说明的是，本申请实施例中的“xx之前”或者“xx之后”不包括“xx”本身，如上述第x1个目标子帧之前的(x1-1)个目标子帧不包括第x1个目标子帧，第y1个目标子帧之后的(N-y1)个目标子帧不包括第y1个目标子帧，在此统一说明，以下不再赘述.
示例性的，假设x1不为1，则第一资源、第二资源和第三资源的位置分布图可以如图7所示。其中，第x1个目标子帧之前的(x1-1)个目标子帧可以包括第二资源上的第一个目标子帧至第二资源上的第(x1-1)个目标子帧，第y1个目标子帧之后的(N-y1)个目标子帧包括第二资源上的第(y1+1)个目标子帧至第二资源上的第N个目标子帧。第二资源上的第x1个目标子帧至第y1个目标子帧虽然用于映射WUS的序列，但是不用于传输对应的WUS，也就是说，第二资源上的第x1个目标子帧至第y1个目标子帧上的WUS被丢弃(drop)。需要说明的是，本申请实施例中，被丢弃(drop)可以理解为，第一资源和第二资源的时域重叠资源上的目标子帧还可以用于映射WUS的序列，但是不用于传输WUS。
或者，示例性的，假设x1等于1，则第一资源、第二资源和第三资源的位置分布图可以如图8所示。其中，第x1个目标子帧之前的(x1-1)个目标子帧为0个目标子帧，第y1个目标子帧之后的(N-y1)个目标子帧包括第二资源上的第(y1+1)个目标子帧至第二资源上的第N个目标子帧。第二资源上的第1个目标子帧至第y1个目标子帧虽然用于映射WUS的序列，但是不用于传输对应的WUS，也就是说，第二资源上的第1个目标子帧至第y1个目标子帧上的WUS被丢弃(drop)。
需要说明的是，图8中示例性的以第一资源的起始时域位置早于第二资源的起始位置为例进行说明。当然，第一资源的起始时域位置也可能与第二资源的起始位置相同，本申请实施例对此不作具体限定。
另一种可能的实现方式中，第一资源与第二资源在时域上重叠部分的第一个子帧 为第二资源的第x2个目标子帧，第一资源与第二资源在时域上重叠部分的最后一个子帧为第二资源的第y2个目标子帧，x2为小于或者等于N的正整数，y2为大于或者等于N的正整数。第三资源包括：第x2个目标子帧之前的(x2-1)个目标子帧。
示例性的，第一资源、第二资源和第三资源的位置分布图可以如图9所示。其中，第x2个目标子帧之前的(x2-1)个目标子帧包括第二资源上的第一个目标子帧至第二资源上的第(x2-1)个目标子帧.第二资源上的第x2个目标子帧至第N个目标子帧虽然用于映射WUS的序列，但是不用于传输对应的WUS，也就是说，第二资源上的第x2个目标子帧至第N个目标子帧上的WUS被丢弃(drop)。
场景二：第一资源与第二资源在时域上重叠部分的第一个子帧为第二资源的第x3个所述目标子帧，第一资源与所述第二资源在时域上重叠部分的最后一个子帧为第二资源的第y3个目标子帧，x3为小于或者等于N的正整数，y3为小于或者等于M的正整数。目标子帧为可用于映射WUS的序列的子帧。N为实际用于映射WUS的序列的目标子帧的个数，可以理解为WUS的实际持续时间；M为WUS的最大持续时间内目标子帧的个数，可以理解为WUS的最大持续时间。当然，WUS的实际持续时间可以小于等于WUS的最大持续时间。例如M＝1024，表示WUS的最大持续时间为1024，同时可以理解为WUS的最大持续时间内包含1024个目标子帧，即WUS的最大持续时间内可以用于映射WUS序列的目标子帧个数为1024。此时，N的取值可以为1，2，4，8，16，32，64，128，256，512或者1024中的任意一个值。
其中，该场景下，第三资源包括：第x3个目标子帧之前的S1个目标子帧，以及第y3个目标子帧之后的S2个目标子帧，其中，S1为整数，S2为整数，S1+S2≤N。可以理解，第x3个目标子帧至第N个目标子帧上的WUS的序列被映射到第(y3+1)个目标子帧至第(y3+S2)个目标子帧上，这也就意味着，第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)。需要说明的是，本申请实施例中，WUS被延迟发送(postpone)可以理解为，第一资源和第二资源的时域重叠资源上的WUS，以及重叠资源之后资源上的WUS均被延迟发送，即假设没有第一资源时WUS原本在目标子帧Z上发送，则当有第一资源，且第一资源是目标子帧Z时，WUS在目标子帧Z+1发送，然后在后续的目标子帧上继续发送WUS。
示例性的，假设x3不为1，则第一资源、第二资源和第三资源的位置分布图可以如图10或者图11所示。其中，第x3个目标子帧之前的S1个目标子帧包括第二资源的第一个有效子帧至第二资源的第(x3-1)个目标子帧，第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的第(N+y3-x3+1)个目标子帧，S1+S2＝N，S1＝x3-1，S2＝N-x3+1。
或者，示例性的，假设x3不为1，则第一资源、第二资源和第三资源的位置分布图可以如图12所示。其中，第x3个目标子帧之前的S1个目标子帧包括第二资源的第一个有效子帧至第二资源的第(x3-1)个目标子帧，第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的最后一个目标子帧、以及第二资源之后的WUS资源上的部分目标子帧，其中，S1+S2＝N，S1＝x3-1。可以看出，当第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个 WUS资源处，或者可能与WUS资源和PO之间的gap重叠，或者可能与PO重叠。进一步的，可选的，本申请实施例中，当第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧中，超出第二资源的结束位置的目标子帧可以被丢弃(drop)。比如，如图13所示，第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的最后一个目标子帧，S1+S2＜N。这样可以避免当第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个WUS资源处，或者可能与WUS资源和PO之间的gap重叠，或者可能与PO重叠的问题。
或者，示例性的，假设x3等于1，则第一资源、第二资源和第三资源的位置分布图可以如图14或图15所示。其中，第x3个目标子帧之前的S1个目标子帧包括0个目标子帧，第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的第(N+y3)个目标子帧，S1+S2＝N，S1＝0,S2＝N。
需要说明的是，图14或图15中示例性的以第一资源的起始时域位置早于第二资源的起始位置为例进行说明。当然，第一资源的起始时域位置也可能与第二资源的起始位置相同，本申请实施例对此不作具体限定。
需要说明的是，图14或图15中示例性的以第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后的第(N+y3)个目标子帧未超出第二资源的结束位置为例进行说明。当然，第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后的第(N+y3)个目标子帧可能超出第二资源的结束位置，此时的处理方式可参考图13或者图14的处理方式，在此不再赘述。
可选的，本申请实施例中，对于上述延迟发送(postpone)的场景，为了避免当第x3个目标子帧至第N个目标子帧上的WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个WUS资源处，或者可能与WUS资源和PO之间的gap重叠，或者可能与PO重叠的问题，或者为了避免超出第二资源的结束位置的目标子帧被丢弃(drop)之后可能影响WUS的性能的问题，因此本申请实施例中，若第一资源与第二资源在时域上重叠，则可以将WUS的发送位置前移，使得第三资源的时域起始位置可以相对于第二资源或者第一资源的时域起始位置提前K个目标子帧，其中，K为第一资源和第二资源的时域重叠部分的子帧的个数，K为正整数。这样可以保证WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置不会超出第二资源的结束位置，从而可以避免当WUS被延迟发送(postpone)之后，第y3个目标子帧之后的S2个目标子帧的结束位置可能超出第二资源的结束位置到下一个WUS资源处，或者可能与WUS资源和PO之间的gap重叠，或者可能与PO重叠的问题。
示例性的，第一资源、第二资源和第三资源的位置分布图可以如图16所示。其中，第x3个目标子帧之前的S1个目标子帧包括第二资源的起始位置之前的K个目标子帧、以及第二资源的第一个有效子帧至第二资源的第(x3-1)个目标子帧，K＝y3-x3+1；第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的第N个目标子帧，S1+S2＝N，S1＝K+x3-1，S2＝N-y3。
或者，示例性的，第一资源、第二资源和第三资源的位置分布图可以如图17所示。其中，第x3个目标子帧之前的S1个目标子帧包括第二资源的起始位置之前的K个目标子帧、以及第二资源的第一个有效子帧至第二资源的第(N-K)个目标子帧，第y3个目标子帧之后的S2个目标子帧为0，S1+S2＝N，S1＝K+N-K＝N，S2＝0。应当理解，当N小于K时，第x3个目标子帧之前的S1个目标子帧包括目标子帧A之前的N个目标子帧，目标子帧A为第二资源的起始位置之前的第K-N个目标子帧，S1＝N。
或者，示例性的，第一资源、第二资源和第三资源的位置分布图可以如图18所示。其中，第x3(x3＝1)个目标子帧之前的S1个目标子帧包括第一资源的起始位置之前的K个目标子帧，K＝y3；第y3个目标子帧之后的S2个目标子帧包括第二资源的第(y3+1)个目标子帧至第二资源的第N个目标子帧，S1+S2＝N，S1＝K，S2＝N-y3。
可选的，本申请实施例中，可以是在第一资源和第二资源的时域起始位置重叠(即x3＝1)时，才将第三资源的时域起始位置相对于第二资源的时域起始位置提前K个目标子帧，本申请实施例对此不作具体限定。
需要说明的是，本申请实施例中，上述第二资源的第一个目标子帧至第二资源的第N个目标子帧也可以理解为现有的没有下行传输间隔资源插入WUS资源场景下的WUS的实际持续时间上的目标子帧，比如图1a所示的WUS的实际持续时间上的目标子帧。相应的，上述包含第二资源的第一个目标子帧至第二资源的第N个目标子帧的资源也可以定义为第四资源，该第四资源为持续时间小于或者等于WUS的最大持续时间的唤醒信号资源，可以理解为现有的没有下行传输间隔资源插入WUS资源的场景下，根据WUS的实际持续时间确定的用于传输WUS的资源，比如根据图1a所示的WUS的实际持续时间确定的用于传输WUS的资源，在此统一说明，以下不再赘述。
可选的，本申请实施例中，若第一资源与第二资源在时域上重叠资源上目标子帧的个数较多，则对于场景一，WUS被丢弃(drop)后对WUS检测性能可能影响比较大。只有第一资源与第二资源在时域上重叠资源上目标子帧的个数较少时，才能减少WUS被丢弃(drop)后对WUS检测性能的影响。基于此，本申请实施例中，若第一资源与第二资源在时域上重叠，则网络设备可以在确定第一资源的持续时间不小于第二阈值的情况下采用上述场景二中的延迟发送(postpone)方式发送WUS，终端设备可以在确定第一资源的持续时间不小于第二阈值的情况下采用上述场景二中的延迟发送(postpone)方式接收WUS；网络设备可以在确定第一资源的持续时间小于第二阈值的情况下根据上述场景一中的丢弃(drop)方式发送WUS，终端设备可以在确定第一资源的持续时间小于第二阈值的情况下根据上述场景一中的丢弃(drop)方式接收WUS。这样可以降低WUS被丢弃(drop)后对WUS检测性能的影响。
可选的，上述终端设备侧的第二阈值可以是基站配置的，本申请实施例对此不作具体限定。当然，本申请实施例中，网络设备也可以直接向终端设备发送信令以指示终端设备WUS的发送方式为延迟发送(postpone)方式还是丢弃(drop)方式，本申请实施例对此不做具体限定。
基于本申请实施例提供的通信方法，由于本申请实施例中，若用于传输WUS的第二资源与下行传输间隔资源在时域上重叠，则在第二资源中除与第一资源重叠部分之外的部分或全部资源上接收或发送WUS，不在第一资源与第二资源在时域上重叠部 分接收或发送WUS，因此第一资源与第二资源在时域上重叠部分可以进行下行数据或者下行信道的传输，从而可以减少下行信道拥塞，降低对网络设备(如基站)调度的影响。
其中，上述步骤S601至S603中的网络设备或者终端设备的动作可以由图3所示的通信装置300中的处理器301调用存储器303中存储的应用程序代码以指令该网络设备执行，本实施例对此不作任何限制。
可选的，本申请实施例中，也可以是网络设备确定第一资源，进而若第一资源与第四资源在时域上重叠，在第三资源上发送WUS。终端设备确定第一资源，进而若第一资源与第四资源在时域上重叠，在第三资源上接收WUS。其中，第三资源与第一资源在时域上不重叠。第一资源为下行传输间隔资源，第四资源为持续时间小于或者等于WUS的最大持续时间的WUS资源。
可选的，本申请实施例中，若第一资源与第四资源在时域上重叠，网络设备在第三资源上向终端设备发送WUS，包括：在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，网络设备在第三资源上向终端设备发送WUS，P和Q均为正整数。也就是说，本申请实施例中，在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，网络设备才进一步确定第一资源与第四资源是否在时域上重叠；否则，在(P×WUS的最大持续时间)小于(Q×第一阈值)的情况下，网络设备认为WUS传输中没有第一资源。
可选的，本申请实施例中，若第一资源与第四资源在时域上重叠，终端设备在第三资源上接收来自网络设备的WUS，包括：在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，终端设备在第三资源上接收来自网络设备的WUS，P和Q均为正整数。也就是说，本申请实施例中，在(P×WUS的最大持续时间)不小于(Q×第一阈值)的情况下，终端设备才进一步确定第一资源与第四资源是否在时域上重叠，否则，在(P×WUS的最大持续时间)小于(Q×第一阈值)的情况下，终端设备认为WUS传输中没有第一资源。
示例性的，这里P和Q的取值可以均为1；或者，P的取值为1，Q的取值为大于1的正整数；或者，Q的取值为1，P的取值为大于1的正整数。
当然，本申请实施例中，终端设备或网络设备还可以通过比较第一类(type-1)CSS的长度(R max)与第一阈值来确定对于WUS，是否存在下行传输间隔资源，本申请实施例对此不作具体限定。
其中，第一资源、第二资源、第三资源和第四资源的相对位置的具体描述可参考图6所示的实施例中对于第一资源、第二资源和第三资源的相对位置的具体描述，在此不再赘述。
可选的，本申请上述实施例中，唤醒信号在第三资源上发送，可以理解为唤醒信号是按照第三资源上目标子帧的先后顺序来发送的，例如先发送第三资源上的目标子帧i上的唤醒信号，然后再发送第三资源上的目标子帧i+1上的唤醒信号，在此统一说明，以下不再赘述。
可以理解的是，以上各个实施例中，由第一通信装置实现的方法和/或步骤，也可以由实现上述第一通信装置功能的芯片系统实现，由第二通信装置实现的方法和/或步 骤，也可以由实现上述第二通信装置功能的芯片系统实现。

可选的，收发模块1901具体用于：在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第二资源在时域上重叠，在第三资源上接收唤醒信号，P和Q均为正整数。
另一种可能的实现方式中，处理模块1902，用于确定第一资源，第一资源为下行传输间隔资源；收发模块1901，用于若第一资源与第四资源在时域上重叠，在第三资源上接收唤醒信号；其中，第四资源为持续时间小于或者等于该唤醒信号的最大持续时间的唤醒信号资源，第三资源与第一资源在时域上不重叠。
可选的，收发模块1901具体用于：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，在该第三资源上接收该唤醒信号，P和Q均为正整数。
若该通信装置190为上述方法实施例中的第二通信装置，或者包含上述第二通信装置的装置，或者为可用于第二通信装置的部件，则一种可能的实现方式中，处理模块1902，用于确定第一资源，第一资源为下行传输间隔资源。收发模块1901，用于若第一资源与第二资源在时域上重叠，在第三资源上发送唤醒信号，其中，第二资源为根据唤醒信号的最大持续时间确定的用于传输唤醒信号的资源；第三资源包括第二资源中除与第一资源在时域上重叠部分之外的部分或全部资源。
可选的，收发模块1901具体用于：在(P×唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第二资源在时域上重叠，在第三资源上发送唤醒 信号，P和Q均为正整数。
另一种可能的实现方式中，处理模块1902，用于确定第一资源，第一资源为下行传输间隔资源；收发模块1901，用于若第一资源与第四资源在时域上重叠，在第三资源上发送唤醒信号；其中，第四资源为持续时间小于或者等于该唤醒信号的最大持续时间的唤醒信号资源，第三资源与第一资源在时域上不重叠。
可选的，收发模块具体用于：在(P×该唤醒信号的最大持续时间)不小于(Q×第一阈值)的情况下，若第一资源与第四资源在时域上重叠，在该第三资源上发送该唤醒信号，P和Q均为正整数。
其中，上述方法实施例涉及的各步骤的所有相关内容均可以援引到对应功能模块的功能描述，在此不再赘述。
在本实施例中，该通信装置190以采用集成的方式划分各个功能模块的形式来呈现。这里的“模块”可以指特定ASIC，电路，执行一个或多个软件或固件程序的处理器和存储器，集成逻辑电路，和/或其他可以提供上述功能的器件。在一个简单的实施例中，本领域的技术人员可以想到该通信装置190可以采用图3所示的通信装置300的形式。
