具体实施方式
下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于多种通信系统，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、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信技术(5th generation wireless systems，5G)系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(transmission reference point，TRP)等，本申请实施例并不限定。在本申请中以5G基站为例进行说明。
本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(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、增强现实(Augmented Reality，AR)终端、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)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
处于RRC_IDLE态或RRC_INACTIVE态的UE在每一个寻呼周期都需要监听PO。所述PO包含多个下行控制信道监听时机(PDCCH monitor occasion)。将UE在PO处检测到的PDCCH称为寻呼下行控制信息(paging，Downlink Control Information，paging DCI)，将该paging DCI所调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)承载的信息称为寻呼消息(paging message)。UE为了能够成功的检测到paging DCI和寻呼消息，需要在PO之前完成同步、自动增益控制(Automatic Gain Control，AGC)等操作。且每个寻呼周期中，UE都需要进行一次测量。因此，在PO之前，UE需要先处理一个或多个同步信号块(Synchronizing Signal Block，SSB)。而UE处理的SSB的个数，可能会随着信道条件的不同而变化。且不同UE的PO和SSB之间的距离也可能不同。
寻呼的寻呼帧(paging frame，PF)和PO由以下公式决定：
PF的系统帧号(system frame number，SFN)满足条件：
(SFN+PF_offset)×T＝(T/N)×(UE_ID×N)；
其中，SFN是PF的系统帧号，PF_offset是PF的偏移量，UE_ID是UE的ID号，T是非连续接收(Discontinuous Reception，DRX)周期。N是一个DRX周期内的寻呼帧的个数。
指示PO的索引号i_s由以下公式决定：i_s＝floor(UE_ID/N)×Ns。
其中，UE_ID是UE的ID号，i_s是指示PO的索引号，floor(·)是向下取整函数，N 是一个DRX周期内的寻呼帧的个数，Ns是一个寻呼帧内PO的个数。
其中UE_ID＝5G-S-TMSI×1024，5G-S-TMSI为48bit长的bit字符串。
一个天线端口符号上的信道特性可以从另一个天线端口推导出，则认为这两个端口准共位置(Quasi Co-Location，QCL)，从一个端口获得的信道估计结果，可以用于另一个端口。
QCL有四种类型：QCL-TypeA具有多普勒偏移、多普勒扩展、平均时延、时延扩展特性，作用是获得信道估计信息；QCL-TypeB具有多普勒偏移、多普勒扩展特性，作用是获得信道估计信息；QCL-TypeC具有多普勒偏移、平均时延特性，作用是获得RSRP等测量信息；QCL-TypeD具有空间接收天线参数特性，作用是辅助UE波束赋形。
为了减少UE接收不必要的PO而造成的功耗，可以在PO之前引入一个寻呼指示(paging early indication，PEI)信号，PEI信号可提前告知UE是否需要唤醒UE接收PO。PEI相对于PO和SSB处在不同位置会带来不同的节电效果，合适的配置可以获得较好的节电增益，配置不合理时，节电增益将大大降低，甚至会呈现负效果。
在PO之前引入一个PEI信号，可以在接收PO之前通知UE在一个或多个寻呼周期中是否需要唤醒UE来接收PO。如果UE不需要接收PO，则该UE可以保持或进入睡眠状态，从而减少接收PO的功耗，还可以减少从睡眠状态切换到接收PO状态以及从接收PO状态切换到睡眠状态(称之为ramp up和ramp down)所需要的额外功耗。所述PEI信号的时域位置对UE节省功耗的效果有着重要的作用。如果PEI位置配置不合适，可能导致UE需要额外增加接收PEI所带来的ramp up和ramp down的功耗，使得节电效果下降，甚至出现反效果。合理的配置PEI的位置是实现UE省电的关键因素。
在实现上，UE在接收PO之前需要处理一个或多个SSB来实现同步、AGC、(同频(同频或者异频)小区测量、服务小区测量等目的。
在不同的信道条件下，UE对SSB个数的要求可能不同。例如对于小区中心的UE而言，信道条件较好，UE需要少量，如一个，SSB即可达到同步和测量的效果，因此UE在PO之前只需要处理一个SSB。当UE位于小区边缘时，信道条件差，一个SSB可能不能满足同步的精度要求，此时，UE需要处理多个SSB才能达到同步、测量等需求。
对于不同的场景，UE在一个寻呼周期内执行的操作(包括，处理的SSB的数量)不同，能达到最佳节电增益所对应的PEI的位置也不相同。
不同类型或者能力的UE，对SSB个数的要求可能不同。例如，有4，2或1个接收天线的UE，所需要处理的SSB个数不同，能达到最佳节电增益所对应的PEI的位置也不相同。例如，普通UE和弱能力UE(reduced capability UE，RedCap UE)，所需要处理的SSB个数不同，能达到最佳节电增益所对应的PEI的位置也不相同。
因此，固定的一个PEI位置不能满足需求。基于此，本申请提出一种信号发送和接收方法、装置、设备和存储介质，在尽可能低的资源开销和复杂度前提下能够获取尽可能高的节电增益。
结合下述实施例对信号发送和接收方法、装置、设备和存储介质进行详细介绍。

如图5所示，所述PEI发送窗为PO之前一段距离，但PEI发送窗的结束位置不是PO开始的位置，而是距离PO一定距离的位置。在此情况下，PEI发送窗截止位置到PO之间的距离可以是预定义的固定值。或者PEI发送窗结束的位置到PO之间的距离由高层参数配置。
例如，所述PEI发送窗的配置信息和UE能力/UE类型/DRX配置相关。其中，PEI发送窗的配置包括如下一种或多种：PEI发送窗的起始位置，PEI发送窗截止位置，PEI发送窗窗的长度。
例如，网络/基站侧根据UE的能力来配置PEI发送窗，包括PEI发送窗的起始位置，PEI发送窗截止位置以及PEI发送窗的长度。例如，所述UE能力包括以下至少之一：接收天线数，发送天线数，是否支持覆盖增强，支持的最大(下行或者上行)带宽。例如，所述DRX 配置包括：第一类DRX配置，或第二类DRX配置。其中，所述，第二类DRX配置包括DRX周期大于或等于1024×10ms。所述，第一类DRX配置包括DRX周期小于1024×10ms。
PO_PEI_offset为大于或等于SSB周期的毫秒级别，如50ms，80ms等。例如，PO_PEI_offset的单位为Slot，如40slots，80slots等。PO_PEI_offset的最大值或者最小值为大于或等于SSB周期的毫秒级别。例如，PEI发送窗内至少有一个SSB出现的机会。PO_PEI_offset可以和SSB的周期值相关，例如PO_PEI_offset大于N个SSB周期；或者，PO_PEI_offset大于或等于N个SSB周期，即保证在PEI发生窗内有N个SSB出现的机会。例如，PO_PEI_offset的最大值或者最小值大于N个SSB周期；或者，PO_PEI_offset的最大值或者最小值大于或等于N个SSB周期，即保证在PEI发生窗内有N个SSB出现的机会。例如，PO_PEI_offset的值等于N倍SSB周期加一个偏移量offset，其中N≥0，offset≥0。例如，PO_PEI_offset的最大值或者最小值等于N倍SSB周期加一个偏移量offset。例如，PO_PEI_offset取值范围取决于不同场景或UE能力或UE类型。例如，对于普通UE而言，PO_PEI_offset的范围为0-3个SSB周期；对于减少复杂度的UE(RedCap UE)而言，PO_PEI_offset的范围为0-5个SSB周期。
基站周期地发送PEI信号。例如，基站在PEI发送窗内周期地发送PEI信号。例如，PEI信号的发送周期是根据SSB周期确定的，例如PEI信号的发送周期和SSB周期相同。例如，均为20ms。如此可保证在PEI发送窗内的每一个SSB附近都有一个PEI发送机会，且每一个PEI的位置和相邻的SSB的位置之间的距离相等。PEI信号的发送周期为SSB周期的倍数。例如，PEI的最大发送周期或最小发送周期为SSB周期的倍数。
例如，在同一个PEI发送窗内发送的PEI信号的内容完全一致。
例如，UE在一个寻呼周期至少检测一个PEI。
例如，PO_PEI_offset的值为固定值，如60ms。例如，PO_PEI_offset的值由高层参数配置。高层参数配置的值就作为实际的PEI发送窗的大小。例如，PO_PEI_offset的值由高层参数配置，且高层参数配置的为一个范围值(如最大值)，UE根据实际情况选择实际采用的PEI接收窗。
定义PEI发送窗可以避免基站只在一个位置上发送PEI从而导致UE漏检的问题，同时还可以避免基站需要频繁发送PEI而导致的额外的能耗/资源开销问题。在PEI发送窗内总是会有SSB接收的机会，从而可以令PEI的位置与SSB位置相邻，通过增加睡眠时间来最大化节电增益。也可使得新版UE(例如，3GPP Release 17或者之后版本的UE)可以像老式UE(例如，3GPP Release 17之前版本的UE)一样，选择/使用SSB来做测量、同步等工作。
在一个实施例中，提供PEI信号与SSB的位置关系。
为了获取更大的节电增益，UE应尽量减少ramp up/down的机会，增加深度睡眠的时间。对于不同UE而言，PO之前的SSB与PO之间的距离随机，当PEI位于SSB周围的时候，UE不必多次醒来，而能集中一段时间处理SSB和PEI，可以使UE获得较高的节电增益。
PEI的时域位置与相关联SSB相关。例如，PEI与相关联SSB之间的位置关系由预定义的方式，高层信令，系统消息，UE能力，UE类型，或DRX参数配置中至少之一确定。
例如，所述相关联的SSB至少满足以下关系之一：
所述相关联的SSB为与PEI距离最近的SSB；在本申请中，当有多个SSB时，将距离PEI最近的SSB称之为与PEI相邻的SSB；
所述相关联的SSB为与PEI具有准共位置(quasi-colocation，QCL)关系的SSB；
所述相关联的SSB为与PEI具有相同波束方向或相同准共位置类型D(QCL-Type D)关系的SSB；
所述相关联的SSB与PEI相对应(correspond)；
所述相关联的SSB与PEI具有相同的索引；例如，PEI与SSB均为多波束发送，且PEI索引分别为0-3，SSB索引也为0-3。则索引相同(例如都为1)的PEI与SSB相对应。
所述相关联的SSB的索引与PEI的索引具有相同排列位置；
所述相关联的SSB的索引在SSB索引集合中位置与PEI的索引在PEI索引集合中排列位置相关；例如，配置的SSB索引集合为{1，3，5}，配置的PEI索引集合为{2，4，6}，则索引为3的SSB与索引为4的PEI在对应索引集合中位置相同(都是第二个索引)，那么，索引为3的SSB与索引为4的PEI相关联。
所述相关联的SSB由高层信令或者系统消息配置；
所述相关联的SSB为预定义方式确定(例如，具有最小SSB索引或者最大SSB索引)。
例如，所述PEI与相关联的SSB之间的位置关系至少与以下因素之一相关：
载波频率(carrier frequency)，子载波间隔(sub-carrier spacing)，SSB图样，SSB周期，SSB索引，SSB与控制资源集(control resource set，CORESET)0的复用图样(multiplexing pattern)，频谱类型，频谱范围。SSB图样取决于高层信令ssb-PositionsInBurst。例如，频谱类型包括，授权频谱或非授权频谱。
例如，PEI与相关联SSB在同一个半帧(half frame)内传输。例如，PEI与相关联SSB在同一个半帧内占用不同符号。
例如，PEI与相关联SSB在同一个时隙传输。例如，PEI在SSB所在时隙的最前面N1个符号传输，1≤N1≤4。例如，PEI在SSB所在时隙的最前面1个或2个符号传输。这样既可以保证减小PDCCH传输的影响(PDCCH通常在一个时隙的前三个符号)，也可以保证UE在集中时间内处理PEI与SSB。
例如，PEI在相关联SSB之前传输。例如，PEI的发送时机从相关联SSB开始位置(例如，SSB索引最小的位置---实际发送SSB的索引是由广播消息/高层信令ssb-PositionsInBurst通知的，不一定从0开始)之前的n个时隙开始，n≥1。例如，PEI的发送时机的开始位置或者结束位置为相关联SSB开始位置之前的n个时隙，n≥1。例如，PEI在相关联SSB之后传输，例如，PEI的发送时机从相关联SSB起始位置(即SSB索引最小或者索引最大的位置)之后的第n个时隙开始，n≥1。
在一个实例中，Case A：
15kHz SCS：PEI在半帧内发送符号的索引包括集合{{0，1，2，...，13}/{2，8}}+14×n中至少之一。(除去SSB)
其中，载波频率小于或等于3GHz，n＝0,1。
其中，载波频率大于3GHz，且属于第一频率范围(frequency range 1，FR1)，n＝0,1,2,3.
其中{A}/{B}表示集合{A}与{B}的差集，即由属于集合{A}但是不属于集合{B}的元素组成。
其中，符号索引0为半帧中第一个符号的索引，符号索引1为半帧中第二个符号的索引，依次类推。
可以再从中选一些符号索引作为实施例。例如，对于与SSB索引为i的相关联的PEI，其在半帧内发送符号的索引包括集合{0，1，6，7}+14*n+i*6中至少之一。其中，i＝0或1。
在一个实例中，Case B：
30kHz SCS:PEI在半帧内发送符号的索引包括集合{{0，1，2，...，27}/{4，8，16，20}}+28×n中至少之一。(除去SSB)。
其中，载波频率小于或等于3GHz，n＝0。其中，载波频率大于3GHz，且属于第一频率范围3GHz，n＝0,1。
例如，对于与SSB索引为i的相关联的PEI，其在半帧内发送符号的索引包括集合{0，1，2，3，12，13}+14×n+i×6中至少之一。其中，i为偶数。例如，对于与SSB索引为j的相关联的PEI，其在半帧内发送符号的索引包括集合{2，3，12，13，14，15}+14×n+j×6中至少之一。其中，j为奇数。
在一个实例中，Case C：
30kHz SCS:PEI在半帧内发送符号的索引包括集合{{0，1，2，...，13}/{2，8}}+14×n中至少之一。(除去SSB{2,8}+14·n}
其中，载波频率小于或等于3GHz，n＝0,1。其中，载波频率大于3GHz，且属于第一频率范围，n＝0,1,2,3。
其中，对于非成对频偏，载波频率小于1.88GHz，n＝0,1。其中，载波频率大于或等于1.88GHz，且属于第一频率范围，n＝0,1,2,3。
例如，对于与SSB索引为i的相关联的PEI，其在半帧内发送符号的索引包括集合{0，1，6，7}+14*n+i*6中至少之一。其中，i＝0，1，2，3。
在一个实例中，Case D：
120kHz SCS:PEI在半帧内发送符号的索引包括集合{{0，1，2，...，27}/{4，8，16，20}}+28×n中至少之一。(除去SSB{4,8,16,20}+28·n)其中，载波频率属于第二频率范围(frequency range 2，FR2)，n＝0，1，2，3，5，6，7，8，10，11，12，13，15，16，17，18。
例如，对于与SSB索引为i的相关联的PEI，其在半帧内发送符号的索引包括集合{0，1，2，3，12，13}+14×n+i×6中至少之一。其中，i为偶数。例如，对于与SSB索引为j的相关联的PEI，其在半帧内发送符号的索引包括集合{2，3，12，13，14，15}+14×n+j×6中至少之一。其中，j为奇数。
在一个实例中，Case E：
240kHz SCS:PEI在半帧内发送符号的索引包括集合{{0，1，2，...，55}/{8，12，16，20，32，36，40，44}}+56*n中至少之一。其中，载波频率属于第二频率范围，n＝0，1，2，3，5，6，7，8。
例如，对于与SSB索引为i的相关联的PEI，其在半帧内发送符号的索引包括集合{0，1，12，13}+14×n+i+mod(I，4)×12中至少之一。其中，i为整数。
在一个实施例中，第一频率范围包括6GHz以下的频带。
在一个实施例中，第二频率范围包括24GHz到52.6GHz的频带，或者，第二频率范围包括24GHz到100GHz的频带。
例如，PEI与相关联SSB之间的位置关系可配。定义PEI与相关联SSB之间的距离为PEI_SSB_offset。例如，所述PEI_SSB_offset为PEI的起始位置和相关联SSB的起始位置之 间的距离。例如，所述PEI_SSB_offset为PEI的起始位置和与该PEI波束方向相同的SSB位置之间的距离。例如，所述PEI_SSB_offset为PEI的起始位置和SSB的指定索引位置(如SSB索引号为1)之间的距离。例如，所述PEI_SSB_offset为PEI的结束位置和相关联SSB的起始位置之间的距离。例如，所述PEI_SSB_offset为PEI的起始位置和相关联SSB的结束位置之间的距离。例如，所述PEI_SSB_offset为PEI的结束位置和相关联SSB的结束位置之间的距离。
例如，PEI_SSB_offset的绝对值小于半个SSB周期。当定义PEI位于相关联SSB之前或之后时，所述SSB指的是与PEI之间的距离小于半个SSB周期的SSB。
在一个实例中，PEI_SSB_offset的值始终大于或等于0。采用预定义的方式说明PEI和相关联SSB的相对位置。例如，PEI位于相关联SSB的前面，或PEI位于SSB后面，或PEI和SSB在时域位置上重叠，其中，slot级别重叠，即PEI和SSB可以在同一slot处理，但二者占用的符号不同；或者，占用的符号相同，但频率资源不同。
以PEI_SSB_offset表示PEI的起始位置和SSB的起始位置之间的距离为例说明如下。
如6所示，假如预定义PEI位于SSB之前，且PEI的持续时间：duration等于3个slot。当PEI_SSB_offset刚好等于3个slot时，此时PEI和SSB紧挨着。当PEI_SSB_offset大于3个slot时，则PEI在SSB之前，但非紧挨着，UE在接收完PEI之后，接收SSB之前有一段可用来睡眠的时间。当PEI_SSB_offset小于3个slot时，则UE在部分slot上既有PEI又有SSB。当PEI_SSB_offset等于0时，PEI的起始位置和SSB的起始位置重叠。在此时，如果SSB的处理时间大于3个slot，则PEI的所有接收时机都与SSB重叠。
需要说明的是，本申请中所述duration为PEI的持续时间，当PEI为PDCCH(基于下行控制信息(downlink control information，DCI)格式)时，duration可以是搜索空间(search space set)配置中的参数。当PEI为序列形式时，duration可以是连续发送PEI的时隙数量。
如果PEI在SSB之前且PEI_SSB_offset为PEI的结束位置和相关联SSB的起始位置之间的距离，则PEI_SSB_offset＝0表示PEI和SSB紧邻。
如果PEI位于SSB之后，则SSB的接收时间大于PEI_SSB_offset时，表明PEI和SSB在时域上有重叠。
例如，当预定义PEI在SSB之前或SSB之后时，PEI_SSB_offset应满足条件：PEI和SSB在时域上无重叠。即，PEI位于SSB之前时，要求PEI的所有检测时机均在SSB之前。例如，PEI在SSB之前，PEI_SSB_offset为PEI的起始位置和SSB的起始位置之间的距离，PEI的duration为3个slot时，要求PEI_SSB_offset大于或等于3个slot。
例如，由于PEI的持续时间(duration)或SSB的处理时间导致PEI和SSB在时域有重叠时，UE只处理未重叠部分的PEI。例如，由于PEI的持续时间(duration)或SSB的处理时间导致PEI和SSB在时域有重叠但在频率上没有重叠时，UE在重叠的时间部分既检测PEI又处理SSB。
在一个实例中，PEI_SSB_offset的值可以为正，可以为负也可以为0。PEI_SSB_offset的正负值用来表示PEI和相关联SSB的前后关系。例如，PEI_SSB_offset为正值时，表明PEI在SSB之前，PEI_SSB_offset为负值时，表明PEI在SSB之后。或相反的，PEI_SSB_offset 为正值时，表明PEI在SSB之后，PEI_SSB_offset为负值时，表明PEI在SSB之前。
以PEI_SSB_offset表示PEI的起始位置和SSB的起始位置之间的距离为例，PEI_SSB_offset＞0，表示PEI的起始位置位于SSB起始位置之前；PEI_SSB_offset＝0，表示PEI起始位置和SSB起始位置重叠；PEI_SSB_offset＜0，表示PEI起始位置在SSB起始位置之后。
与上述实例类似。例如，当PEI_SSB_offset＞0或PEI_SSB_offset＜0时，PEI_SSB_offset应满足条件：PEI和SSB在时域上无重叠。例如，当PEI_SSB_offset表示PEI的起始位置和SSB的起始位置之间的距离时，为了使得PEI与SSB时域无重叠，要求PEI_SSB_offset＞duration或者PEI_SSB_offset＜﹣SSB处理时间。例如，不限制PEI_SSB_offset，由于PEI的持续时间(duration)或SSB的处理时间导致PEI和SSB在时域有重叠时，UE只处理未重叠部分的PEI。例如，由于PEI的持续时间(duration)或SSB的处理时间导致PEI和SSB在时域有重叠时，UE在重叠部分既检测PEI又处理SSB。
例如，PEI和相关联SSB的位置关系由高层信令。例如，第一高层信令决定PEI和相关联SSB的前后关系；第二高层信令决定PEI和相关联SSB之间的偏移，i.e.，PEI_SSB_offset。例如，若第三高层信令配置为PEI_SSB_offset，则表示PEI在相关联SSB之前，且偏移为PEI_SSB_offset；若第四高层信令配置为PEI_SSB_offset，则表示PEI在相关联SSB之后，且偏移为PEI_SSB_offset。
例如，第一高层信令取决于UE能力，UE类型，DRX参数，频率范围，或频谱类型中至少之一。
例如，第二高层信令取决于UE能力，UE类型，DRX参数，频率范围，或频谱类型中至少之一。
在一个实施例中，提供UE在何位置检测PEI信号，检测PEI信号的个数，如果漏检如何操作的方法。
基站在PEI发送窗内周期性的发送PEI，UE可在对应位置接收PEI。当PEI发送窗内有多个PEI发送机会时，UE并不需要检测每一个PEI。且UE在不同的PEI发送机会上检测PEI最终实现的节电增益不同，在PEI接收窗内的第一个PEI检测机会上检测PEI并不总能实现好的节电增益。为了实现最优的节电增益，需要定义UE在哪个PEI机会检测PEI。
值得注意的是，本申请中所述的SSB附近指的可以是SSB之前，SSB之中，也可以是SSB之后。
在一个实例中，基站在PEI发送窗内的所有PEI位置上发送PEI信号，UE只检测PEI发送窗内UE实际处理的第一个SSB相关联(或附近)的PEI信号。例如，PEI发送窗内包含3个SSB处理时机，且UE处理窗内的第一个SSB，则UE在第一个SSB附近的PEI发送位置上检测PEI，并根据PEI的指示执行对应操作。如果UE不在PEI发送窗内的第一个SSB处理机会处处理SSB，UE处理第二个SSB，则UE不检测PEI发送窗内的第一个PEI发送机会。UE在PEI发送窗内的第二个SSB附近，即第二个PEI发送位置检测PEI(如图3和图4所示)。
例如，UE只检测PEI发送窗内与相关联SSB具有预定义位置关系的一个或多个PEI信号。例如，所述预定义位置关系由偏置(offset)确定。例如，所述偏置与UE能力，UE类型，频率范围，频偏类型中至少之一确定。
例如，若UE成功检测到一个PEI，则无论UE是否处理PEI发送窗内的剩余SSB，UE均不再检测剩余PEI。例如，若UE在PEI发送窗内的第一个PEI检测位置上未成功检测到PEI，则UE在下一个PEI位置上继续检测PEI。例如，若UE成功检测到一个PEI，则不再检测当前发送窗内其他PEI。例如，一个发送窗内仅发送或配置L个PEI。其中，L为正整数，例如，L＝1。例如，一个配置PEI的搜索空间集(search space set)周期内仅发送或配置L个PEI。
例如，如果UE在PEI发送窗内处理的第一个SSB附近没有PEI发送机会，例如PEI在SSB之前，刚好被划在PEI发送窗之外，则UE在下一个PEI发送机会处检测PEI。
例如，如果PEI发送窗内的SSB均不被UE处理，例如PEI发送窗内有两个SSB处理机会，但是UE只处理了PEI发送窗外的一个SSB，则UE在PEI发送窗内的第一个PEI发送位置上检测PEI。例如，如果PEI发送窗内的SSB均不被UE处理，则UE在PEI发送窗内的最后一个PEI发送位置上检测PEI。例如，如果PEI发送窗内的SSB均不被UE处理，则UE在该寻呼周期不检测PEI。
在一个实例中，UE总是在PEI发送窗内的第一个PEI发送位置上检测PEI。无论UE是否处理第一个PEI发送位置附近的SSB，均在第一个PEI发送位置上检测PEI。例如，UE在一个寻呼周期内只需成功检测一次PEI，若检测成功，则不检测后续PEI。
在一个实例中，例如，UE根据上一寻呼周期中PO之前处理的SSB的个数来决定检测PEI的位置。如：UE上一个寻呼周期在PO之前只处理了一个SSB，则UE在下一个寻呼周期在离PO最近的SSB附近检测PEI。如果上一个寻呼周期在PO之前处理了三个SSB，则下一个寻呼周期也从PO前第三个SSB附近开始检测PEI，如果检测失败，则在下一个SSB处理之中/后再次检测PEI。
例如，令PEI发送窗的长度大于PO和该寻呼周期处理的第一个SSB之间的距离。PEI发送窗的长度小于PO和该寻呼周期处理的第一个SSB之间的距离时，在PEI发送窗内的第一个PEI位置检测PEI。
在一个实例中，UE根据上一个或多个寻呼周期的测量结果来确定检测PEI的位置。例如，UE根据上一个寻呼周期的测量结果(如参考信号接收功率(RSRP，Reference Signal Received Power))值来确定PEI的位置。例如，UE根据前M个寻呼周期的测量结果的平均值来确定PEI的位置。例如，设置RSRP门限，根据上一个或多个寻呼周期的RSRP值的范围决定接收SSB的个数，进而确定PEI的位置。如：上一/多个寻呼周期的RSRP＞A，则表明信道条件较好，则认为下一寻呼周期，UE只需要处理一个SSB，UE处理距离PO最近的SSB，并在该SSB附近，即距离PO最近的PEI位置上检测PEI。当上一/多个寻呼周期的B＜RSRP＜A时，表明当前信道条件一般，UE可能需要在PO之前处理2个SSB，则该寻呼周期UE处理距离PO较近的两个SSB，并且在处理第一个SSB附近检测PEI。当上一/多个寻呼周期的RSRP＜B时，表明当前信道条件较差，UE需要处理3个或更多SSB，且在窗内处理的第一个SSB附近检测PEI。
例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，UE执行预定义操作。例如，预定义操作为UE在PO处接收paging DCI。预定义操作为UE在PO处不接收paging DCI。例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE跳过该paging cycle的PO接收，默认sleep操作。例如，若 UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE是否接收寻呼由高层参数指示。
例如，没有PEI检测机会包括PEI检测时机中至少一个或所有PEI检测时机与至少以下之一资源碰撞或重叠：
SSB资源；
SMTC窗；
测量间隔；
定位参考信号；
系统消息；
随机接入响应窗；
控制资源集合0，或，
预配置时频资源。
在一个实施例中，为了获取更大的节电增益，UE应尽量减少ramp up/down的功耗，增加深度睡眠的时间。当PEI位于SSB周围的时候在同样的信道条件下可以使UE获得较高的节电增益。因此，当确定PEI位置时，以SSB为参考是一个有效的选择。
本申请通过两级指示的方法来确定PEI的位置。将PEI与SSB关联，可以使得UE获取最高的省电增益。且唯一的PEI位置可以减少基站多次发送PEI的功率消耗。唯一的PEI发送位置也可以使得UE准确地找到PEI的检测时机，从而获取PEI信号，实现省电的效果。
在一个实施中，提供一种第一级指示方式，即通过SSB确定PEI信号的位置。
如图7所示，PEI位置与PO之前的第N个SSB相关联，N＞0。例如，第N个SSB指的是第N个SMTC window内的SSB。例如，第N个SSB指的是第N个SSB突发。例如，第N个SSB指的是第N个SSB突发中具有某一SSB索引的SSB，如SSB索引等于0。例如，N的取值范围为1-5，如N＝1，N＝3。需要说明的是，此处定义距离PO最近的SSSB突发出现的机会为PO之前的第一个SSB突发，以此往前类推。
例如，N的值为预定义的固定值，例如N＝1，N＝3等。
例如，N的值可配。例如，由高层参数决定。例如，高层参数配置N＝1，则在该参数改变之前，PEI位置与PO之前的第一个SSB关联。当UE环境变化时，例如从小区中央移动到小区边缘后，可以通过重配N的值来改变PEI发送/接收的位置。如，配置N＝3，PEI位置与PO之前的第3个SSB关联，UE在PO之前的第三个SSB相关联的位置测PEI。
例如，N的值由其它信令指示，如物理层信令。例如由PEI携带，用来指示下一/多个寻呼周期的N值。或者由paging DCI或其它信令携带。
例如，高层参数配置了N值的范围，具体的N值由UE决定。例如，高层参数配置了N值的范围，具体采用的N值与UE能力/UE类型相关。基站/网络侧根据UE能力/UE类型来决定具体的N值。例如，高层配置N的取值为3或5，对于高UE能力等级的UE而言默认采用N＝3，对于低UE能力等级的UE而言默认采用N＝5。
例如，N值由UE上报。例如，UE根据之前的测量结果，根据信道条件等确定最适合的N值，上报给基站/网络侧。例如，基站/网络侧配置默认值，且该值对UE可知，当UE未上 报数值时，采用默认值。当UE上报数值之后，则采用UE上报的数值。
第二级指示为PEI与相关联的SSB之间的位置关系。
确定N值之后，通过确定PEI和与之相关联的SSB之间的位置关系即可确定准确的PEI发送/接收位置。其中PEI和与之相关联的第N个SSB之间的位置关系可以如实施例2的描述。例如，基站可以在确定PEI位置后多次发射PEI。
例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE按照未引入PEI时(Legacy UE；Rel-15/16UE)的操作执行。默认的，UE在PO处正常接收paging DCI。例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE是否正常接收寻呼由高层参数指示。
在一个实施例中，本申请通过两级指示的方法来确定PEI的位置。首先确定与PEI位置相关联的参考点，可以使得UE获取较高省电增益的同时配置更加灵活。
所述参考点位于PO之前。例如，该参考点的位置(即距离PO的位置)由高层参数决定。例如，该参考点的位置与SSB周期相关。例如。该参考点距离PO之间的距离是SSB周期的整数倍；例如。该参考点距离PO之间的距离是SSB周期的整数倍加一个offset。例如，该参考点具有特殊的特征，例如该参考点的SFN mod N＝0，N为正整数，例如，N＝256。
例如，一个参考点对应一个PEI位置。例如，有C个参考点分别关联C个PEI位置，其中1≤C≤5。例如，C个参考点相关联的PEI位置上发送的PEI内容完全相同。例如，UE检测所有的PEI位置。例如，UE在一个paging cycle仅检测一个PEI。
确定参考点之后通过PEI和参考点之间的位置关系来确定PEI的位置。例如，PEI与参考点之间的距离为PEI_Refer_offset。例如，PEI_Refer_offset为PEI的起始位置到参考点的距离。例如，PEI_Refer_offset为PEI的结束位置到参考点的距离。类似于本文其它实施例中描述的PEI与SSB之间的位置关系，PEI_Refer_offset可以有不同的配置，参考点可以在PEI之前，与PEI起始位置重叠或参考点在PEI之后。
上述实施例中描述的PEI与相邻SSB之间的位置关系同样适用于用来描述PEI与参考点之间的位置关系。PEI_SSB_offset的取值和配置也同样可以用来描述PEI_Refer_offset。
PEI的时域位置与相关联的参考点相关。例如，PEI与相关联参考点之间的位置关系固定，例如，采用预定义的方式，或由高层信令决定，或由系统消息配置。
例如，所述PEI与相关联的参考点之间的位置关系至少与以下因素之一相关：
载波频率(carrier frequency)，sub-carrier spacing，频谱类型。例如，频谱类型包括，授权频谱或非授权频谱。
例如，PEI与相关联参考点在同一个半帧(half frame)内传输。例如，PEI与相关联参考点在同一个半帧内占用不同符号。
例如，PEI在相关联参考点之前传输。例如，PEI的发送时机从相关联参考点之前的n个时隙开始，n≥1。例如，PEI的发送时机的开始位置或者结束位置为相关联参考点位置之前的n个时隙，n≥1。例如，PEI在相关联SSB之后传输，例如，PEI的发送时机从相关联参考点之后的第n个时隙开始，n≥1。
例如，PEI_refer_offset的绝对值小于半个SSB周期。
Case 1：例如，PEI_refer_offset的值始终大于或等于0。采用预定义的方式说明PEI和相 关联参考点的相对位置。例如，预定义PEI位于相关联参考点的前面，当PEI_refer_offset＝5slot时，PEI位于参考点之前相距5个slot的位置。再例如，预定义PEI位于参考点后面，当PEI_refer_offset＝5slot时，PEI位于参考点之后相距5个slot的位置。PEI_refer_offset＝0slot时，PEI从参考点位置开始。
Case 2：例如，PEI_refer_offset的值可以为正，可以为负也可以为0。PEI_refer_offset的正负值用来表示PEI和相关联SSB的前后关系。例如，PEI_refer_offset＝0表明PEI位置从参考点处开始。PEI_refer_offset为正值时，表明PEI在参考点之前，PEI_refer_offset为负值时，表明PEI在参考点之后。或相反的，PEI_参考点_offset为正值时，表明PEI在参考点之后，PEI_参考点_offset为负值时，表明PEI在参考点之前。
例如，PEI和相关联参考点的位置关系由高层信令。例如，第一高层信令决定PEI和相关联参考点的前后关系；第二高层信令决定PEI和相关联参考点之间的偏移，i.e.，PEI_refer_offset。例如，若第三高层信令配置为PEI_refer_offset，则表示PEI在相关联参考点之前，且偏移为PEI_refer_offset；若第四高层信令配置为PEI_refer_offset，则表示PEI在相关联参考点之后，且偏移为PEI_refer_offset。
例如，在配置参考点和PEI_SSB_offset时，需满足PEI起始位置到参考点之间有SSB出现的机会。例如，此处的SSB指的是一个SSB接收窗内的SSB。例如，此处的SSB指的是一个SS block burst。例如，此处的SSB指的是具有某个特定索引/波束方向的SSB。例如，PEI起始位置到参考点之间有且仅有一个SSB出现的机会。例如，PEI_SSB_offset的值不大于SSB周期。例如，PEI起始位置到参考点之间有SSB出现的机会，且PEI与该SSB之间的距离小于一个域值，如s个时隙(其中s为正整数，例如，1-9)，或1/4个SSB周期。例如，PEI与参考点之间没有SSB出现的机会，且PEI与距离最近的SSB之间的距离小于一个阈值，如半个SSB周期，或1/4个SSB周期，或s个时隙。
例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE按照未引入PEI时的操作执行(UE按照legacy UE、Rel-15/Rel-16UE的操作来执行)。默认的，UE在PO处正常接收paging DCI。例如，若UE被配置了PEI的时频域资源但未检测到PEI或在该寻呼周期没有检测机会，则UE是否正常接收寻呼由高层参数指示。
在一个实施例中，本申请所述PEI可以为DCI形式，也可以是一个序列的形式。
例如，所述PEI在时域上具有周期性。例如，PEI的周期等于SSB的周期。例如，PEI的周期等于N个SSB的周期。
例如，所述PEI在频域上采用和CORESET 0相同的频域资源。例如，所述PEI在频域上采用和paging DCI频域相邻的频域资源。例如，当PEI为DCI格式时，如果paging DCI配置了CORESET 0，则PEI可配置为CORESET 0。例如，如果paging DCI配置了CORESET 0，则PEI可配置为与CORESET 0相邻的频域位置，如此可保证UE不需要在不同频段/频率之间相互切换，减少额外功耗。
在一个实施例中，提供第一类PEI可能的资源碰撞时的解决方法。例如，在本实施例中PEI为第一类PEI。例如，以所述第一类PEI为DCI-based PEI。
例如，当PEI配置CSS(common search space，公共搜索空间)type-0时，UE不期望PEI 在与SSB相对应的RE位置发送。例如，当PEI配置不是CSS type-0，且PEI与SSB的RE有重叠时，UE不期望在所述重叠资源上监测PDCCH(检测PEI)。例如，当SSB和PEI有相同的QCL-type D属性时，允许SSB和PEI在相同符号上接收。例如，UE不期望在配置了CRS的资源上监听PDCCH(检测PEI)。例如，对于不可用资源(unavailable resource)，UE不期望监听PDCCH(检测PEI)。
例如，当channel state information-reference signal(CSI-RS)和PEI有相同的QCL-type D属性时，允许CSI-RS和PEI在相同符号的不同子载波上接收。例如，当PEI与配置了Type1-PDCCH CSS set的PDCCH冲突，且与Type1-PDCCH CSS set的PDCCH没有相同的QCL-type D属性时，UE不监听PEI。
例如，当PEI与PDSCH的资源重叠时，PEI与PDSCH的优先级取决于PDSCH承载的信息类型和加扰调度PDSCH的PDCCH的RNTI类型。例如，当所述PDSCH由C-RNTI，CS-RNTI，MCS-C-RNTI加扰的PDCCH调度时，优先映射PEI。当所述PDSCH由RA-RNTI，MsgB-RNTI，P-RNTI，SI-RNTI或TC-RNTI加扰的PDCCH调度时，优先映射PDSCH。当所述PDSCH为系统消息时，优先映射PDSCH。
例如，当PEI与随机接入响应窗(random access response window，RAR window)发生资源碰撞时，根据触发RAR window的原因决定优先级。例如，当RAR由初始接入触发(Triggered by initial access)时，则RAR优先级高，优先处理RAR；当RAR由波束/无线链路监听失败(Triggered by beam failure/radio link monitoring failure)触发时，则PEI优先级高，优先处理PEI。
例如，当PEI与其它信令/信号发生资源碰撞时，所述资源承载的信息对连接态UE透明，即，基站通过配置第一资源通知连接态UE所述资源承载的信息内容是PEI或是其它信号/信道。
例如，当数据传输资源和第一资源重叠时，根据数据传输和第一资源的优先级和决定是否接收数据。例如，第一资源与PEI相关。
所述数据传输和第一资源的优先级包括如下一种或多种情况：
当所述数据传输资源为PDSCH数据传输资源时，数据传输和第一资源的优先级由PDSCH承载的信息类型，加扰调度PDSCH的PDCCH的RNTI类型，和触发方式中至少之一确定；

当所述数据传输资源为PDCCH数据传输时，数据传输和第一资源的优先级由PDCCH承载的信息类型，PDCCH承的控制信息格式，加扰PDCCH的RNTI类型，PDCCH相关的控制资源集，PDCCH相关的搜索空间类型中至少之一确定；
当所述数据传输资源为参考信号时频资源时，数据传输和第一资源的优先级由参考信号的类型，参考信号的时间特征，参考信号的触发方式中至少之一确定；
当所述数据传输资源为当SSB时频资源时，数据传输和第一资源由PEI相关的时频资源确定。
例如，当第一资源与PDSCH的资源重叠时，第一资源与PDSCH的优先级取决于PDSCH 承载的信息类型和加扰调度PDSCH的PDCCH的RNTI类型。例如，当所述PDSCH由C-RNTI，CS-RNTI，MCS-C-RNTI加扰的PDCCH调度时，优先映射PEI。当所述PDSCH由RA-RNTI，MsgB-RNTI，P-RNTI，SI-RNTI或TC-RNTI加扰的PDCCH调度时，优先映射PDSCH。当所述PDSCH为系统消息时，优先映射PDSCH。
例如，当第一资源与参考信号的资源重叠时，第一资源与参考信号的优先级取决于由参考信号的类型，参考信号的时间特征，参考信号的触发方式中至少之一确定。例如，当所述参考信号为SSB或定位参考信号时，优先映射SSB或定位参考信号。例如，当所述参考信号为CSI-RS时，若CSI-RS时间特征为周期性，则不接收周期性CSI-RS。例如，当所述参考信号为CSI-RS时，若CSI-RS时间特征为DCI触发，则接收CSI-RS。
例如，当第一资源与随机接入响应窗(random access response window，RAR window)发生资源碰撞时，根据触发RAR window的原因决定优先级。例如，当RAR由初始接入触发(Triggered by initial access)时，则RAR优先级高，优先处理RAR；当RAR由波束/无线链路监听失败(Triggered by beam failure/radio link monitoring failure)触发时，则RAR优先级低。
例如，当PEI与其它信令/信号(包括但不限于SSB，信道状态信息参考信号(Channel-state information Reference Signal，CSI-RS)，unvailable resource block(RB)(NR-U)，measurement gap，某一类PDSCH，随机接入响应(Random Access Response，RAR window))发生资源重叠/碰撞导致无法监听时，UE监听PO。例如，当PEI与其它信令/信号发生资源重叠/碰撞导致无法监听时，UE不监听PEI，是否监听PO由高层配置。当PEI与其它信令/信号发生资源重叠/碰撞导致无法监听时，UE不监听PO。
例如，UE配置了监听PEI的时机，但未检测到PEI时，UE监听PO。例如，UE配置了监听PEI的时机，但未检测到PEI时，UE默认不监听PO。例如，UE未检测到PEI时，UE是否监听PO由高层配置/信令决定。
在一个实施例中，提供第二类PEI可能的资源碰撞时的解决方法。例如，在本实施例中PEI为第二类PEI。例如，所述第二类PEI为sequence-based PEI。
例如，当PEI与SSB具有相同的QCL-type D属性时，允许PEI与SSB配置在相同的符号不同子载波上，否则，UE不期望PEI与SSB配置在相同的符号上。例如，UE不期望PEI与CRS在相同的符号上。当PEI与CRS在相同符号上时，UE不检测PEI。例如，在unavailable resource，UE不期望检测PEI。例如，当PEI与CSI-RS，DM-RS，PRS具有相同的QCL-type D属性时，允许PEI与CSI-RS，DM-RS，PRS在相同的符号上，否则，UE不期望PEI与CSI-RS，DM-RS，PRS在相同的符号上。
例如，UE不期望监听PEI，如果PEI与配置了Type0/0A/1/2-PDCCH CSS set的PDCCH发生资源重叠/碰撞。例如，UE不期望监听Type3-PDCCH CSS或UE specific search space，如果PEI与配置了Type3-PDCCH CSS或UE specific search space的PDCCH发生资源重叠/碰撞。
例如，当PEI与PDSCH的资源重叠时，PEI与PDSCH的优先级取决于PDSCH承载的信息类型和加扰调度PDSCH的PDCCH的RNTI类型。例如，当所述PDSCH由C-RNTI， CS-RNTI，MCS-C-RNTI加扰的PDCCH调度时，优先映射PEI。当所述PDSCH由RA-RNTI，MsgB-RNTI，P-RNTI或TC-RNTI加扰的PDCCH调度时，优先映射PDSCH。当所述PDSCH为系统消息时，优先映射PDSCH。
例如，当PEI与随机接入响应窗(RAR window)发生资源碰撞时，根据触发RAR window的原因决定优先级。例如，当RAR由初始接入触发(Triggered by initial access)时，则RAR优先级高，优先处理RAR；当RAR由波束/无线链路监听失败(Triggered by beam failure/radio link monitoring failure)触发时，则PEI优先级高，优先处理PEI。
例如，当PEI与其它信令/信号发生资源碰撞时，所述资源承载的信息对连接态UE透明，即，基站将告知连接态UE所述资源承载的信息内容是PEI或是其它信号/信道。
例如，当PEI与其它信令/信号(包括但不限于SSB，CRS，unvailable RB(NR-U)，measurement gap，某一类PDSCH，RAR window)发生资源重叠/碰撞导致无法监听时，UE执行legacy操作，默认监听PO。例如，当PEI与其它信令/信号发生资源重叠/碰撞导致无法监听时，UE是否监听PO由高层配置。
例如，UE配置了监听PEI的时机，但未检测到PEI时，UE默认执行legacy操作，默认监听PO。例如，UE配置了监听PEI的时机，但未检测到PEI时，UE默认不监听PO。例如，UE未检测到PEI时，UE是否监听PO由高层配置/信令决定。
