Description

参考信号接收与发送方法、设备及*** 技术领域
本申请涉及通信技术领域，尤其涉及参考信号接收与发送方法、设备及***。
背景技术
在无线通信***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用于指示终端设备是否需要监听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，则代表着网络设备在以该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，终端设备则不需要监听该PDCCH。
然而，当终端设备在检测在寻呼机会前是否存在WUS时，即使网络设备在寻呼机会前没有发送WUS，终端设备也需要从WUS的起始子帧开始监听，直到WUS的最大持续时间(即最大WUS duration)结束才知道没有WUS，这对终端设备来说也是一种功耗浪费。
因此，如何在检测以PO对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息，和/或在检测在PO前是否存在WUS时，降低终端设备的功耗，是目前亟待解决的问题。
发明内容
本申请实施例提供参考信号接收与发送方法、设备及***，可以降低终端设备的功耗。

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的简要介绍如下。
第一，PO：
终端设备处于空闲态时，网络设备通过寻呼机制告知终端设备是否需要进入连接态以进行信息交互。在该情况下，终端设备必须监听PDCCH才能完成后续响应。但是，若在空闲态时，终端设备一直监听PDCCH，将对终端设备功耗造成极大的浪费。空闲态下的不连续接收周期(discontinuous reception，DRX)工作机制固定，采用固定的DRX周期，处于降低功耗的考虑，网络设备和终端设备通过协商，终端设备仅在以DRX周期上的一个PO所在的子帧(以下也可以称之为PO位置)为起始子帧的PDCCH搜索空间内以盲检的形式检测PDCCH。其中，PDCCH搜索空间是指目标PDCCH可能出现的备选(candidate)位置的集合，PO位置指示终端设备监听PDCCH的起始位置，从而确定一个PDCCH搜索空间的起始位置，进而根据该PDCCH搜索空间的起始位置盲检PDCCH。在一个PDCCH搜索空间内，一个方块可看做是一个candidate。
需要说明的是，本申请实施例中的PDCCH可以是窄带物联网(narrowband internet of things，NB-IoT)中的窄带PDCCH(narrowband，NPDCCH)，也可以是其它PDCCH，本申请实施例对此不作具体限定。比如如图1所示，在NB-IOT***中，NPDCCH搜索空间中最多有八种candidate位置，分别记为candidate0、candidate1、candidate2、……、candidate7。其中，本申请实施例中的备选位置占用h个子帧，h为该备选位置上NPDCCH的重复次数，h为正整数，在此统一说明，以下不再赘述。现有技术中，终端设备在以PO对应的子帧为起始子帧的NPDCCH搜索空间中，依次盲检不同的candidate，直到检测成功为止。如果都不成功，则在下一个DRX周期内，终端设备继续在以PO对应的子帧为起始子帧的NPDCCH搜索空间中监听NPDCCH，以此类推。其中，图1中的Rmax表示以PO对应的子帧为起始子帧的NPDCCH搜索空间的长度，也可以理解为NPDCCH的最大重复次数，在此统一说明，以下不再赘述。
其中，本申请实施例中的DRX周期可以是预先配置在终端设备上的，也可以是网络设备通过***消息配置给该终端设备的，本申请实施例对此不作具体限定。该DRX周期也可以视为空闲态终端设备定期醒来的周期，在此统一说明，以下不再赘述。
如图2所示，为网络设备上配置的DRX周期内PO位置的示意图。由图2可以看出，对于网络设备来说，可以在一个DRX周期内配置多个PO。而对于和该网络设备通信的多个终端设备中的任意一个终端设备，该终端设备仅在DRX周期上的一个PO位置处醒来。因此，若配置了DRX，终端设备就需要精确地计算出终端设备在DRX周期内的何时需要醒来，以监听可能发生的寻呼。下面给出终端设备醒来的PO位置的确定方式如下：
其中，PO位置由***帧号(system frame number，SFN)以及子帧号共同确定，即可以通过SFN以及子帧号来标识PO位置，也就是寻呼调度消息应该出现的NPDCCH搜索空间的起始位置。SFN标识寻呼调度消息应该出现的NPDCCH搜索空间的起始位置所在的***帧位置，子帧号标识寻呼调度消息应该出现的NPDCCH搜索空间的起始位置在该***帧上的子帧位置。一个***帧包括10个子帧，如子帧0、子帧1、子帧2、子帧3、……、子帧8和子帧9，在此统一说明，以下不再赘述。
其中，本申请实施例中，终端设备可以根据网络设备发送的寻呼配置参数确定PO对应的SFN以及子帧号。比如，满足以下公式(1)的SFN即可作为一个PO对应的SFN：
SFN mod T＝(T div N)*(UEID mod N)；   公式(1)
其中，mod表示取余；div表示整除，即取整；T表示DRX周期；N取值等于min(T，nB)，即取T和nB之间的小值，取值范围是{T，T/2，T/4，T/8，T/16，T/32，T/64，T/128，T/256，T/512，T/1024}；nB表示寻呼密度，即一个DRX周期内PO的个数，取值范围是{4T，2T，T，T/2，T/4，T/8，T/16，T/32，T/64，T/128，T/256，T/512，T/1024}；UEID取值等于(国际移动用户识别码(international mobile subscriber identity，IMSI)mod 4096)，其中，每个终端设备的IMSI是唯一的。
比如，一个PO对应的子帧号可以通过以下公式(2)确定：
i_s＝floor(UEID/N)mod Ns；    公式(2)
其中，floor表示向下取整；Ns＝max(1，nB/T)，表示存在PO的***帧上有多少个PO，取值范围是(4，2，1)；i_s表示子帧号的索引，即计算出i_s之后，可以通过查表方式得到一个PO对应的子帧号；mod、N和UEID的相关描述可参考上述公式(1)，在此不再赘述。
由上述公式(1)和公式(2)可以看出，一旦T、nB、以及UEID参数确定，终端设备根据上述公式(1)就可在一个DRX周期内唯一确定出一个SFN；终端设备根据上述公式(2)就可在一个***帧上唯一确定出一个子帧号，从而根据该***帧号和子帧号，终端设备可以在一个DRX周期内唯一确定出终端设备醒来的一个PO位置。
类似的，对于和网络设备通信的多个终端设备中的任意一个终端设备，网络设备根据上述公式(1)和公式(2)也可以唯一确定出一个DRX周期内该终端设备醒来的一个PO位置，在此不予赘述。
此外，现有技术中，终端设备和网络设备均可以通过上述T、nB、以及UEID参数确定出网络设备在一个DRX周期内配置的所有PO位置。示例性的，如图3所示，以NB-IOT***为例，nB＝4T表示一个***帧内有4个PO，且这4个PO的时域资源分别为子帧0、子帧4、子帧5、子帧9。nB＝2T表示一个***帧内有2个PO，且这2个PO的时域资源分别为子帧4、子帧9。nB＝T表示一个***帧内有1个PO，且这1个PO的时域资源为子帧9。nB＝T/2表示两个***帧内有1个PO，且这1个PO的时域资源为两个***帧中的其中一个***帧的子帧9，图3中示例性的以PO的时域资源为示出的第2个***帧的子帧9和第4个***帧的子帧9为例进行说明。nB＝T/4表示四个***帧内有1个PO，且这1个PO的时域资源为四个***帧中的其中一个***帧的子帧9，图2中示例性的以PO的时域资源为示出的第2个***帧的子帧9为例进行说明。依次类推。
在目前的NB-IoT***中，有两种载波类型：锚点(anchor)载波和非锚点(non-anchor)载波。anchor载波是指承载窄带主同步信号(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)、NPDCCH和窄带物理下行共享信道(narrowband physical downlink shared channel，NPDSCH)的载波。non-anchor载波是指只承载NPDCCH和NPDSCH，不承载NPSS、NSSS和NPBCH的载波。其中，在non-anchor载波上，当终端设备通过以上公式(1)和公式(2)计算出PO位置时，终端设备并不知道以PO对应的子帧为起始子帧的NPDCCH搜索空间中是否有寻呼调度消息，因此终端设备需要盲检NPDCCH。当以PO对应的子帧为起始子帧的NPDCCH搜索空间中有寻呼调度消息时，网络设备会在终端设备能检测到寻呼调度消息的备选位置上发送窄带参考信号(narrowband reference signal，NRS)，以及在检测到寻呼调度消息的备选位置上以及备选位置的第一个子帧的前10个子帧上和备选位置的最后一个子帧的后4个子帧上发送NRS。当以PO对应的子帧为起始子帧的NPDCCH搜索空间中没有寻呼调度消息时，网络设备不会在以上这些位置上发送NRS。
所以，现有技术中，当以PO对应的子帧为起始子帧的NPDCCH搜索空间中没有寻呼调度消息，即使这个终端设备是个信道条件好的终端设备，也需要从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。然而，信道条件好的终端设备的检测能力强，并不需要检测那么多次重复的NPDCCH才能知道是否有寻呼调度消息，这对信道条件好的终端设备来说是一种功耗浪费。
其中，本申请实施例中，信道条件好的终端设备是指某些指标比较好的终端设备，比如：参考信号接收功率(reference signal received power，RSRP)较好，在此统一说明，以下不再赘述。
第二，WUS：
目前，网络设备可以在PO前向终端设备发射WUS，该WUS用于指示终端设备是否需要监听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，则代表着网络设备在以该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，终端设备则不需要监听PDCCH。
当网络设备需要发送WUS时，会通过***消息将相关参数指示给终端设备。这些参数包括：第一比例因子(scaling factor)、WUS的结束位置与PO位置之间的间隔(gap)以及Rmax。其中，WUS的结束位置与PO之间的间隔可以是DRX的间隔、eDRX(extended DRX,eDRX)的短间隔和eDRX的长间隔中的至少一项；第一比例因子的范围为{1/128，1/64，1/32，1/16，1/8，1/4，1/2}，Rmax的相关说明可参考上述图1，在此不再赘述。
终端设备根据如下公式(3)得到WUS的最大持续时间(maximum WUS duration)：
maximum WUS duration＝Rmax*第一比例因子；   公式(3)
由于通过上述公式(1)和公式(2)能确定PO位置，进而，在知道PO位置、gap以及maximum WUS duration的情况下，终端设备就可以确定出WUS的起始位置(或者WUS的起始子帧)，如图4所示。其中，图4中WUS的实际持续时间(WUS actual duration) 是2的指数倍个子帧，比如1、2、4、8、……、maximum WUS duration。
类似的，对于和网络设备通信的多个终端设备中的任意一个终端设备，网络设备根据上述方式也可以确定出WUS的起始位置，在此不予赘述。
此外，由上述关于PO的描述可知，终端设备和网络设备均可以通过上述T、nB、以及UEID参数确定出网络设备在一个DRX周期内配置的所有PO位置，因此，根据上述确定WUS的起始位置的方式，终端设备和网络设备均可以确定出一个网络设备在一个DRX周期内配置的所有WUS的起始位置，在此统一说明，以下不再赘述。
目前，现将技术中，当终端设备在检测在寻呼机会前是否存在WUS时，即使网络设备在寻呼机会前没有发送WUS，这个终端设备是个信道条件好的终端设备，也需要从WUS的起始子帧开始监听，直到WUS的最大持续时间(即最大WUS duration)结束才知道没有WUS，这对信道条件好的终端设备来说也是一种功耗浪费。
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。
此外，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。

在需要检测以PO对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息，和/或在检测在PO前是否存在WUS时，网络设备60根据不连续接收周期内寻呼机会的个数确定第一时长上的时域资源，该时域资源为用于传输参考信号的时频资源中的时域资源；进而，网络设备60在该时频资源上向终端设备70发送参考信号。这样，终端设备70根据不连续接收周期内寻呼机会的个数确定上述第一时长上的时域资源；进而，终端设备70在该时频资源上接收来自网络设备60的参考信号。
或者，可选的，在需要检测以PO对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息，和/或在检测在PO前是否存在WUS时，网络设备60确定第一时长上 的时域资源，该时域资源为用于传输参考信号的时频资源中的时域资源；进而，网络设备60在该时频资源上向终端设备70发送参考信号。这样，终端设备70确定上述第一时长上的时域资源；进而，终端设备70在该时频资源上接收来自网络设备60的参考信号。其中，该时域资源包括第一时域资源和第二时域资源中的至少一个，第一时域资源包括第一时长上的一个或多个寻呼机会对应的子帧、以及一个或多个寻呼机会中的每个寻呼机会对应的子帧之前的X3个子帧和之后的Y3个子帧，其中，X3为大于或者等于0的整数，Y3为大于或者等于0的整数，X3与Y3的和与第三设定值相关。第二时域资源包括第一时长上的一个或多个唤醒信号的起始子帧、以及一个或多个唤醒信号的起始子帧中的每个唤醒信号的起始子帧之前的X3个子帧和之后的Y3个子帧，其中，X3为大于或者等于0的整数，Y3为大于或者等于0的整数，X3与Y3的和与第四设定值相关。
或者，可选的，在需要检测以PO对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息，和/或在检测在PO前是否存在WUS时，网络设备60向终端设备70发送测量子帧的信息；网络设备60根据该测量子帧的信息确定第一时长上的时域资源，该时域资源为用于传输参考信号的时频资源中的时域资源；网络设备60在该时频资源上向终端设备70发送参考信号。终端设备70接收来自网络设备60的测量子帧的信息，根据该测量子帧的信息确定第一时长上的时域资源，该时域资源为用于传输参考信号的时频资源中的时域资源；进而，终端设备70在该时频资源上接收来自网络设备60的参考信号。
上述方案的具体实现将在下述实施例中详细阐述，在此不再赘述。
基于本申请实施例提供的通信***，一方面，在检测以寻呼机会对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息，终端设备在寻呼机会处醒来监听PDCCH时，可以通过第一时长上的若干个参考信号进行测量，从而当测量结果满足一定条件时，可以将该终端设备视为信道条件好的终端设备，进而在以寻呼机会对应的子帧为起始子帧的PDCCH搜索空间中，终端设备不需要盲检完所有的备选位置，可以仅盲检部分备选位置即可确定是否存在寻呼调度消息，从而可以节省终端设备的功耗。另一方面，在检测在寻呼机会前是否存在WUS时，终端设备可以通过第一时长上的若干个参考信号进行测量，从而当测量结果满足一定条件时，可以将该终端设备视为信道条件好的终端设备，终端设备从WUS的起始子帧开始监听，不需要直到WUS的最大持续时间结束才知道没有WUS，可以提前终止WUS的监听，从而可以节省终端设备的功耗。

可选的，上述步骤S701-S703中的时频资源中的频域资源也可以不是寻呼机会或者唤醒信号当前所在的时频资源中的频域资源，也就是说，传输该参考信号的时频资源中的频域资源与寻呼机会或者唤醒信号当前所在的时频资源中的频域资源可以不是同一个频域资源。此时，网络设备可通过第一频域资源指示参数指示给终端设备传输参考信号的时频资源中的频域资源，本申请实施例对此不作具体限定。
可选的，上述步骤S701-S703中的时频资源中的时域资源可以包括第一时域资源和第二时域资源中的至少一个。其中，第一时域资源包括第一时长上的一个或多个寻呼机会对应的子帧、以及一个或多个寻呼机会中的每个寻呼机会对应的子帧之前的X1个子帧和之后的Y1个子帧，其中，X1为大于或者等于0的整数，Y1为大于或者等于0的整数，X1与Y1的和与DRX周期内寻呼机会的个数相关。第二时域资源包括第一时长上的一个或多个唤醒信号的起始子帧、以及一个或多个唤醒信号的起始子帧中的每个唤醒信号的起始子帧之前的X2个子帧和之后的Y2个子帧，其中，X2为大于或者等于0的整数，Y2为大于或者等于0的整数，X2与Y2的和与DRX周期内寻呼机会的个数相关。

场景一：步骤S701-S703中的时频资源中的时域资源可以包括第一时域资源
以上述步骤S701-S703中的时频资源中的时域资源包括第一时域资源为例，则X1 个子帧可以为与一个或多个寻呼机会中的每个寻呼机会对应的子帧连续的前X1个连续子帧，Y1个子帧可以为与一个或多个寻呼机会中的每个寻呼机会对应的子帧连续的后Y1个连续子帧。
示例性的，以X1与Y1的和满足如下公式(4)为例：
X1+Y1＝min{4T/nB，a}-1；      公式(4)
其中，nB表示DRX周期内寻呼机会的个数，也可以称之为寻呼密度；T表示DRX周期；a为第一设定值。假设PO位置如图3所示，16≤a＜32，则：
当nB＝4T时，X1+Y1＝0，此时参考信号对应的时域资源可以如图8中的(a)所示，即包括第一时长上的每个寻呼机会对应的子帧，如寻呼机会所在的***帧上的子帧0、子帧4、子帧5和子帧9。
当nB＝2T时，X1+Y1＝1，假设X1＝1，Y1＝0，此时参考信号对应的时域资源可以如图8中的(b)所示，即包括第一时长上的每个寻呼机会对应的子帧以及与每个寻呼机会连续的前1个子帧，如寻呼机会所在的***帧上的子帧3、子帧4、子帧8和子帧9。
当nB＝T时，X1+Y1＝3，假设X1＝0，Y1＝3，此时参考信号对应的时域资源可以如图8中的(c)所示，即包括第一时长上的每个寻呼机会对应的子帧以及与每个寻呼机会连续的后3个连续子帧，如寻呼机会所在的***帧上的子帧9，以及寻呼机会所在的***帧的下一个连续***帧上的子帧0、子帧1和子帧2。
当nB＝T/2时，X1+Y1＝7，假设X1＝6，Y1＝1，此时参考信号对应的时域资源可以如图8中的(d)所示，即包括第一时长上的每个寻呼机会对应的子帧、以与每个寻呼机会连续的前6个连续子帧、以及与每个寻呼机会连续的后1个子帧，如寻呼机会所在的***帧上的子帧3至子帧9、以及寻呼机会所在的***帧的下一个连续***帧上的子帧0。
当nB＝T/4时，X1+Y1＝15，假设X1＝11，Y1＝4，此时参考信号对应的时域资源可以如图8中的(e)所示，即包括第一时长上的每个寻呼机会对应的子帧、以与每个寻呼机会连续的前11个连续子帧、以及与每个寻呼机会连续的后4个连续子帧，如寻呼机会所在的***帧的上一个连续***帧上的子帧8和子帧9、寻呼机会所在的***帧上的子帧0至子帧9、以及PO所在的***帧的下一个连续***帧上的子帧0至子帧3。
当nB＜T/4时，X1+Y1＝a-1，此时参考信号对应的时域资源具体可参考图8中的(a)至(e)，在此不再一一赘述。
可选的，本申请实施例中，X1与Y1的和可以是网络设备根据DRX周期内寻呼机会的个数、DRX周期、以及第一设定值确定的，比如根据上述公式(4)确定的；或者，X1与Y1的和为与DRX周期内寻呼机会的个数对应的设定值，比如如以下表一或者表二所示，本申请实施例对此不作具体限定。
表一
nB X1+Y1+1

T/2 8
T/4 16
＜T/4 a
表二
nB X1+Y1
4T 0
2T 1
T 3
T/2 7
T/4 15
＜T/4 a-1
可选的，本申请实施例中，第一时域资源上的子帧可以包括普通子帧，也可以包括有效(valid)子帧，本申请实施例对此不作具体限定。其中，在第一时域资源上的子帧全是有效子帧的情况下，寻呼机会对应的子帧可以是寻呼机会所在的子帧，也可以是寻呼机会之后的第一个有效子帧；X1个(连续)子帧为X1个(连续)有效子帧，Y1个(连续)子帧为Y1个(连续)有效子帧，在此统一说明，以下不再赘述。
其中，本申请实施例中，连续有效子帧是指在两个有效子帧之间没有其它有效子帧。比如，假设图8中的(b)中寻呼机会所在的***帧上的子帧3不是有效子帧，寻呼机会所在的***帧上的子帧2为有效子帧，则此时参考信号对应的时域资源可以如图9所示，包括寻呼机会所在的***帧上的子帧2、子帧4、子帧8和子帧9。
可选的，在上述场景一中，本申请实施例提供的参考信号接收与发送方法还可以包括：网络设备向终端设备发送参考信号的第一配置信息，该第一配置信息包括X1、Y1、第一周期(period)、第一时长、第一时长在第一周期内的偏置量(offset)、和第一时长的重复次数中的至少一个，本申请实施例对此不作具体限定。
其中，第一周期和第一时长的相关描述可参考上述部分，在此不再赘述。第一时长在第一周期内的偏置量可以是S1个***帧或者S2个子帧，S1为0或者正整数，S2为0或者正整数。其中，第一时长的重复次数为正整数，(第一时长*第一时长的重复次数)小于或者等于第一周期的长度，第一时长在第一周期内的偏置量小于或者等于第一周期的长度与(第一时长*第一时长的重复次数)的差值，在此统一说明，以下不再赘述。
这样，终端设备接收来自网络设备的第一配置信息之后，可以根据第一配置信息和DRX周期内寻呼机会的个数确定第一时长或第一周期上的时域资源。比如，假设第一配置信息包括X1和Y1中的至少一个，以及第一时长，则终端设备可以根据第一配置信息和DRX周期内寻呼机会的个数确定第一时长上的时域资源；或者，比如，假设第一配置信息包括X1和Y1中的至少一个，第一时长在第一周期内的偏置量和第一时长的重复次数中的至少一个，第一周期和第一时长，则终端设备可以根据第一配置信息和DRX周期内寻呼机会的个数确定第一周期上的时域资源，本申请实施例对此不作具体限定。
示例性的，假设DRX周期＝128个***帧，第一周期＝0.5*DRX周期＝64个***帧，第一时长＝(1/32)*第一周期，第一时长在第一周期内的偏置量为1个***帧，第一 时长的重复次数为2，nB＝2T时参考信号对应的时域资源如图8中的(b)所示，则nB＝2T时，第一周期上的时域资源可以如图10所示，包括该第一周期内第2个***帧至第5个***帧上的子帧3、子帧4、子帧8和子帧9。
可选的，上述实施例以网络设备向终端设备发送第一配置信息为例进行说明，其中，网络设备可以在***消息或者高层信令中向终端设备发送第一配置信息，***消息例如可以是***信息块(system information block，SIB)或者主信息块(master information block，MIB)，高层信令例如可以是无线资源控制(radio resource control，RRC)信令，本申请实施例对此不作具体限定。
可选的，上述X1、Y1、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的全部信息可以由网络设备向终端设备配置，即第一配置信息包括X1、Y1、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数；或者，上述X1、Y1、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的全部信息可以是协议约定好的，此时网络设备不需要向终端设备发送第一配置信息；或者，X1、Y1、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的部分信息可以由网络设备向终端设备配置，X1、Y1、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的部分信息可以是协议约定好的。比如，第一配置信息中可以包括X1或Y1中的至少一个，而第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数可以是协议约定好的，本申请实施例对此不作具体限定。
可选的，若本申请实施例提供的参考信号接收与发送方法应用于NB-IOT***中，则在non-anchor载波上，当以PO对应的子帧为起始子帧的NPDCCH搜索空间中没有寻呼调度消息时，网络设备可以在相应的时频资源上向终端设备发送NRS，该时频资源中的时域资源为上述的第一时域资源，使得终端设备可以根据NRS进行测量。当以PO对应的子帧为起始子帧的NPDCCH搜索空间中有寻呼调度消息时，网络设备可以在相应的时频资源上向终端设备发送NRS，该时频资源中的时域资源为上述的第一时域资源，使得终端设备可以根据NRS进行测量；同时，网络设备会在可以检测到寻呼调度消息的备选位置上以及备选位置的第一个子帧的前10个子帧上和备选位置的最后一个子帧的后4个子帧上发送NRS，使得终端设备可以根据NRS进行解调。当用于解调的NRS和用于测量的NRS有交集(overlap)时，网络设备取二者的并集发送NRS。
示例性的，如图11所示，以nB＝4T，第一时长为4个***帧为例，则按照上述确定第一时域资源的方式，假设网络设备可以在第一时长上的每个PO上发送NRS用于测量。当图11中第4个***帧的子帧0为可以检测到寻呼调度消息的备选位置(即假设可以检测到寻呼调度消息的备选位置占用1个子帧)时，网络设备可以在图11中第4个***帧的子帧0上以及图11中第4个***帧的子帧0的前10个子帧上和图11中第4个***帧的子帧0的后4个子帧上发送NRS用于解调。综上，网络设备可以在第1、2个***帧的子帧0、子帧4、子帧5和子帧9以及第3个***帧的所有子帧以及第4个***帧的子帧0、子帧1、子帧2、子帧3、子帧4、子帧5和子帧9上发送NRS。此时，第3个***帧的子帧0、子帧4、子帧5和子帧9以及第4个***帧的子帧0和子帧既可以发送NRS用于测量又可以发送NRS用于解调，也就是说，网络设备在以上子 帧上发送NRS既用于测量又用于解调。
其中，终端设备在以寻呼机会对应的子帧为起始子帧的PDCCH搜索空间中监听PDCCH时，由于并不知道是否有寻呼调度消息，因此用一定存在NRS的子帧进行测量，用可能存在的能检测到寻呼调度消息的备选位置以及备选位置的第一个子帧的前10个子帧和备选位置的最后一个子帧的后4个子帧上的NRS进行解调，在此统一说明，以下不再赘述。
可选的，本申请实施例中，终端设备在检测以PO对应的子帧为起始子帧的PDCCH搜索空间中是否有寻呼调度消息时，终端设备在寻呼机会处醒来监听PDCCH时，可以根据不连续接周期内寻呼机会的个数确定第一时长上的时域资源，在相应的时频资源上接收来自网络设备的参考信号，进而通过参考信号进行测量获得测量结果，比如进行RSRP测量，以获得信号干扰噪声比(signal to interference plus noise ratio，SINR)。当测量结果满足一定条件时，可以将该终端设备视为信道条件好的终端设备，进而在以寻呼机会对应的子帧为起始子帧的PDCCH搜索空间中，该终端设备不需要盲检完所有的备选位置，可以仅盲检部分备选位置即可确定是否存在寻呼调度消息。比如，如图12所示，覆盖的终端设备可以仅需检测完PDCCH搜索空间中的前3个备选位置即可提前终止，从而可以节省终端设备的功耗。
场景二：步骤S701-S703中的时频资源中的时域资源可以包括第二时域资源
以上述步骤S701-S703中的时频资源中的时域资源包括第二时域资源为例，则X2个子帧可以为与一个或多个唤醒信号中的每个唤醒信号的起始子帧连续的前X2个连续子帧，Y2个子帧可以为与一个或多个唤醒信号中的每个唤醒信号的起始子帧连续的后Y2个连续子帧。
示例性的，以X2与Y2的和满足如下公式(5)为例：
X2+Y2＝min{4T/nB，b}-1；   公式(5)
其中，nB表示DRX周期内寻呼机会的个数，也可以称之为寻呼密度；T表示DRX周期；b为第二设定值，可以是协议约定好的，也可以是网络设备配置的，本申请实施例对此不作具体限定。
示例性的，假设PO位置如图3所示，16≤a＜32，gap＝30ms，WUS最大持续时间＝2ms，则：
当nB＝4T时，X2+Y2＝0，假设每个PO位置对应的WUS的起始子帧如图13中的(a)所示，包括：示出的第4个***帧上的子帧4对应的WUS的起始子帧为示出的第1个***帧上的子帧2，示出的第4个***帧上的子帧5对应的WUS的起始子帧为示出的第1个***帧上的子帧3，示出的第4个***帧上的子帧9对应的WUS的起始子帧为示出的第1个***帧上的子帧7，未示出的第5个***帧上的子帧4对应的WUS的起始子帧为示出的第2个***帧上的子帧2，未示出的第5个***帧上的子帧5对应的WUS的起始子帧为示出的第2个***帧上的子帧3，未示出的第5个***帧上的子帧9对应的WUS的起始子帧为示出的第2个***帧上的子帧7，未示出的第6个***帧上的子帧4对应的WUS的起始子帧为示出的第3个***帧上的子帧2，未示出的第6个***帧上的子帧5对应的WUS的起始子帧为示出的第3个***帧上的子帧3，未示出的第6个***帧上的子帧9对应的WUS的起始子帧为示出的第3个***帧上的子帧7， 未示出的第7个***帧上的子帧4对应的WUS的起始子帧为示出的第4个***帧上的子帧2，未示出的第7个***帧上的子帧5对应的WUS的起始子帧为示出的第4个***帧上的子帧3，未示出的第7个***帧上的子帧9对应的WUS的起始子帧为示出的第4个***帧上的子帧7，则此时参考信号对应的时域资源可以如图13中的(a)所示，即包括第一时长上的每个唤醒信号的起始子帧，如唤醒信号的起始子帧所在的***帧上的子帧2、子帧3和子帧7。
当nB＝2T时，X1+Y1＝1，假设每个PO位置对应的WUS的起始子帧如图13中的(b)所示，包括：示出的第4个***帧上的子帧4对应的WUS的起始子帧为示出的第1个***帧上的子帧2，示出的第4个***帧上的子帧9对应的WUS的起始子帧为示出的第1个***帧上的子帧7，未示出的第5个***帧上的子帧4对应的WUS的起始子帧为示出的第2个***帧上的子帧2，未示出的第5个***帧上的子帧9对应的WUS的起始子帧为示出的第2个***帧上的子帧7，未示出的第6个***帧上的子帧4对应的WUS的起始子帧为示出的第3个***帧上的子帧2，未示出的第6个***帧上的子帧9对应的WUS的起始子帧为示出的第3个***帧上的子帧7，未示出的第7个***帧上的子帧4对应的WUS的起始子帧为示出的第4个***帧上的子帧2，未示出的第7个***帧上的子帧9对应的WUS的起始子帧为示出的第4个***帧上的子帧7，则此时参考信号对应的时域资源可以如图13中的(b)所示，即包括第一时长上的每个唤醒信号的起始子帧以及与每个唤醒信号的起始子帧连续的前1个子帧，如唤醒信号的起始子帧所在的***帧上的子帧1、子帧2、子帧6和子帧7。
当nB＝T时，X2+Y2＝3；或者，当nB＝T/2时，X2+Y2＝7；或者，当nB＝T/4时，X2+Y2＝15；或者，当nB＜T/4时，X2+Y2＝a-1，此时参考信号对应的时域资源具体可参考图13中的(a)和(b)，在此不再一一赘述。
可选的，本申请实施例中，X2与Y2的和可以是网络设备根据DRX周期内寻呼机会的个数、DRX周期、以及第二设定值确定的，比如根据上述公式(5)确定的；或者，X2与Y2的和为与DRX周期内寻呼机会的个数对应的设定值，比如如以下表三或表四所示，本申请实施例对此不作具体限定。

可选的，本申请实施例中，第二时域资源上的子帧可以包括普通子帧，也可以包括有效(valid)子帧，本申请实施例对此不作具体限定。其中，由于唤醒信号的起始子帧为有效子帧，因此在第二时域资源上的子帧全是有效子帧的情况下；X2个(连续)子帧为X2个(连续)有效子帧，Y2个(连续)子帧为Y2个(连续)有效子帧，在此统一说明，以下不再赘述。
其中，本申请实施例中，连续有效子帧是指在两个有效子帧之间没有其它有效子帧。比如，假设图13中的(b)中唤醒信号的起始子帧所在的***帧上的子帧6不是有效子帧，唤醒信号的起始子帧所在的***帧上的子帧5为有效子帧，则此时参考信号对应的时域资源可以如图14所示，包括唤醒信号的起始子帧所在的***帧上的子帧1、子帧2、子帧5和子帧7。
可选的，在上述场景二中，本申请实施例提供的参考信号接收与发送方法还可以包括：网络设备向终端设备发送参考信号的第二配置信息，该第二配置信息包括X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的至少一个，本申请实施例对此不作具体限定。
其中，第一周期、第一时长、以及第一时长在第一周期内的偏置量的相关描述可参考上述场景一，在此不再赘述。
这样，终端设备接收来自网络设备的第二配置信息之后，可以根据第二配置信息和DRX周期内寻呼机会的个数确定第一时长或第一周期上的时域资源。比如，假设第二配置信息包括X2和Y2中的至少一个，以及第一时长，则终端设备可以根据第二配置信息和DRX周期内寻呼机会的个数确定第一时长上的时域资源；或者，比如，假设第二配置信息包括X2和Y2中的至少一个，第一时长在第一周期内的偏置量和第一时长的重复次数中的至少一个，第一周期和第一时长，则终端设备可以根据第二配置信息和DRX周期内寻呼机会的个数确定第一周期上的时域资源，本申请实施例对此不作具体限定。
示例性的，假设DRX周期＝128个***帧，第一周期＝0.5*DRX周期＝64个***帧，第一时长＝(1/32)*第一周期，第一时长在第一周期内的偏置量为1个***帧，第一时长的重复次数为2，nB＝2T时参考信号对应的时域资源如图13中的(b)所示，则nB＝2T时，第一周期上的时域资源可以如图15所示，包括该第一周期内第2个***帧至第5个***帧上的子帧1、子帧2、子帧6和子帧7。
可选的，上述实施例以网络设备向终端设备发送第二配置信息为例进行说明，其中，网络设备可以在***消息或者高层信令中向终端设备发送第二配置信息，***消息例如可以是SIB或者MIB，高层信令例如可以是RRC信令，本申请实施例对此不作具体限定。
可选的，上述X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的全部信息可以由网络设备向终端设备配置，即第一配置信息包括X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长 的重复次数；或者，上述X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的全部信息可以是协议约定好的，此时网络设备不需要向终端设备发送第一配置信息；或者，X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的部分信息可以由网络设备向终端设备配置，X2、Y2、第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数中的部分信息可以是协议约定好的。比如，第一配置信息中可以包括X2和Y2中的至少一个，而第一周期、第一时长、第一时长在第一周期内的偏置量、和第一时长的重复次数可以是协议约定好的，本申请实施例对此不作具体限定。
可选的，本申请实施例中，支持WUS的终端设备在检测在PO前是否存在WUS时，可以根据不连续接周期内寻呼机会的个数确定第一时长上的时域资源，在相应的时频资源上接收来自网络设备的参考信号，进而通过参考信号进行测量获得测量结果，比如进行RSRP测量，以获得SINR。当测量结果满足一定条件时，可以将该终端设备视为信道条件好的终端设备，该终端设备从WUS的起始子帧开始监听，不需要直到WUS的最大持续时间结束才知道没有WUS，可以提前终止WUS的监听，从而可以节省终端设备的功耗。
场景三：步骤S701-S703中的时频资源中的时域资源可以包括第一时域资源和第二时域资源
该场景下，可以按照上述场景一的方式确定第一时域资源(即传输与寻呼机会相关的参考信号的时域资源)，以及，可以按照上述场景二的方式确定第二时域资源(即传输与唤醒信号的起始子帧相关的参考信号的时域资源)，相关描述可参考上述场景一和场景二的描述，在此不再赘述。
