技术领域
本公开涉及通信技术领域，尤其涉及一种节能信号的传输方法、终端和网络侧设备。
背景技术
在5G新空口(New Radio，NR)系统中，支持更大的带宽，更高的吞吐，更复杂的业务以及与其匹配的更复杂的处理技术。另外，终端在空闲态(RRC_IDLE)、非激活态(RRC_Inactive)和连接态(RRC_Connected)均需要检测下行控制信道。目前通信系统中，检测下行控制信道的检测位置均是预先配置好的，且预先会配置很多个检测位置，终端需要在每个检测位置均进行检测。例如：在非连续接收(Discontinuous Reception，DRX)场景，终端需要在每个激活时间(On duration)周期都需要检测下行控制信道。因此，NR系统中引入了节能(power saving)信号，但目前的节能信号无法携带多个节能信息，从而导致节能效果比较差。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
参见图1，图1是本公开实施例可应用的网络结构示意图，如图1所示，包括终端11和网络侧设备12，其中，终端11可以是用户终端(User Equipment，UE)或者其他终端设备，例如：手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定终端的具体类型。网络侧设备12可以是基站，例如：宏站、LTE eNB、5G NR NB等；网络侧设备也可以是小站，如低功率节点(low power node，LPN)、pico、femto等小站，或者网络侧设备可以接入点(access point，AP)；基站也可以是中央单元(central unit，CU)与其管理和控制的多个传输接收点(Transmission Reception Point，TRP)共同组成的网络节点。需要说明的是，在本公开实施例中并不限定网络侧设备的具体类型。
请参见图2，图2是本公开实施例提供的一种节能信号传输方法的流程图，如图2所示，包括以下步骤：
201、终端接收网络侧设备发送的节能信号(power saving信号)；
其中，所述节能信号为多级序列，且所述多级序列至少携带节能标识、节能区域标识和所述多级序列的级指示信息，所述节能标识与节能区域内需要唤醒的终端对应，所述节能区域为所述节能区域标识指示的区域；或者
所述节能信号包括第一级节能信号和第二级节能信号，其中，所述第一级节能信号和所述第二级节能信号分别携带不同的节能信息。
其中，上述节能信号可以包括DRX on之前的节能信号，又可以包括DRX on周期之内的节能信号。另外，上述节能信号可以是用于唤醒一个或者多个终端的信号，例如：上述节能信号可以是唤醒信号(Wakeup Signal，WUS)，或者比WUS概念更宽的节能信号，对此不作限定，例如：上述节能信号还可以是协议中定义的其他信号，或者网络侧设备与终端预先约定的其他信号。
上述节能标识可以是wake up ID，而上述节能区域标识可以是wake up area ID。另外，上述节能信号可以包括一个或者多个节能标识，在一些实施方式中，一个节能标识对应一个终端，或者多个节能标识之间不同组合对应不同的终端。
而节能区域标识可以是指的是节能标识对应终端的归属区域标识，比如在RRC-Connected状态下可以是指小区标识(cell ID)，在RRC-Idle态下可以是指跟踪区标识(Track area ID)或者把跟踪区(Track area)分割为多个区域得到的更小的唤醒区域。
而上述多级序列的级指示信息可以是每级序列的级指示信息，或者部分级序列的级指示信息，例如：用于指示上述多级序列每个级序列或者部分级序列的级数。通过上述级指示信息可以是确定接收到的序列的级数，以避免第一级序列没有接收到，而对第二级序列进行检测导致的功耗浪费。
本公开实施例中，通过上述节能标识、节能区域标识和所述多级序列的级指示信息可以实现唤醒一个或者多个终端，从而提高节能效果。例如：若所述终端位于所述节能区域，且所述节能标识与所述终端对应，则所述终端可以进入唤醒状态。
需要说明的是，上述节能标识、节能区域标识和级指示信息均是节能信息，即上述多级序列至少可以携带3种节能信息。且上述接收可以称作检测。
还需要说明的是，本公开实施例中，携带可以理解为指示，也就是说，上 述节能信号携带节能信息可以称作节能信号指示节能信息。具体可以是，节能信号携带节能信息可以理解为，终端通过解析节能信号能够获取到相应的节能信息。
另外，由于节能信号可以包括第一级节能信号和第二级节能信号，且所述第一级节能信号和所述第二级节能信号分别携带不同的节能信息，从而也可以实现节能信号携带多种节能信息，以提高节能效果。
作为一种可选的实施方式，上述多级序列的级指示信息包括：
每级序列携带的级指示信息；或者
所述多级序列中第一级序列不携带级指示信息，其余级序列携带的级指示信息；或者
所述多级序列中后一级序列携带前一级或者前多级序列的级指示信息。
该实施方式，由于每级序列可以携带的级指示信息，从而终端可以准确地确定接收到的序列的级数。
而上述多个级序列中第一级序列不携带级指示信息，其余级序列携带的级指示信息，或者所述多级序列中后一级序列携带前一级或者前多级序列的级指示信息，这样可以节约节能信号的开销。
需要说明的是，本公开实施例中，上述多级序列存在一定顺序，第一级序列为多个序列中最前面的一级，第二级序列为第一级序列的后一级序列，第三级序列为第二级序列的后一级序列，以此类推。例如：第二级序列携带第一级序列的级指示信息，第三级序列携带第二级序列的级指示信息。
可选的，所述级指示信息包括：
级索引信息(stage index)或者分组索引信息。
下面以两个例子对，上述实施方式进行举例说明：
例1：每一级序列都需要携带多级序列的级指示信息，以本实施例中两级序列为例，第一级gold序列初始相位需要包含1比特的级索引信息，如比特0，第二级gold序列初始相位同样包含1比特初始相位信息，如比特1，如果更多级的序列，指示级索引的比特数自然增加。例如：节能(power saving)信息携带最多信息比特个数为InforNum＝24，第一级(gold)序列初始相位可携 带wake up area ID相关信息(占10比特)与wake up ID相关信息(占8个比特)，第一级序列的stage index信息(占1个比特)；第二级gold序列初始相位可携带wake up area ID相关信息(占10比特)，第二级序列的stage index信息(占1个比特)，第二级序列携带的wake up ID相关信息(占8比特)，两级序列最多支持256*256个wake up ID信息。需要注意的是每一序列中携带的与wake up ID相关信息可以是完整的wake up ID信息，也可以是部分wake up ID信息。
例2：后一级(gold)序列需要携带前一级或者多级(gold)序列携带的级指示信息(例如：分组索引信息)，例如以两级序列为例，第一级gold序列中的每个特定的序列都携带与特定wake up ID相关的信息，如果将第一级序列所有的可能的序列视为一组序列，可以将该组序列再进行分组得到S个子组，每个子组的index可以作为一种分组索引信息。第二级gold序列需要携带与第一级序列中与分组索引信息，该信息可以是第二级gold序列的初始相位的函数。由于对第一级序列进行了分组，将子组index传给了第二级序列，子分组数S值最小可以取1，S值最大可与该级序列中所有序列个数一样多，即每个子分组中序列个数只有1；当S值取1时，等价于第一级序列中没有多级序列的级index，而第二级多级序列中包含一个公共的(例如1比特)第一级序列的级index，这是上述例1，各级序列携带级index的一个特例。显然S值越大越有利于降低序列检测的虚警概率，当然S值越小则越有利于提高特殊序列如正交序列的多用户复用性能。
作为一种可选的实施方式，上述多级序列还携带有如下至少一项：
BWP索引、载波索引(Carrier index)、需要跳过的PDCCH检测周期的个数的指示信息、所述节能信号的资源信息。
上述需要跳过的PDCCH检测周期的个数可以用N_skip表示，即终端需要skip掉的PDCCH检测周期的个数N_skip。
其中，上述资源信息可以是传输节能信号的资源相关的时间或者频率信息。
该实施方式中，可以实现上述节能信号携带更多的节能信息，以进一步提高节能效果。
进一步的，上述载波索引可以为网络侧半静态配置的至少一个载波索引中的载波索引；和/或
所述需要跳过的PDCCH检测周期的个数可以为网络侧半静态配置的至少一个的PDCCH检测周期的跳过个数中的一个。
该实施方式中，可以实现节能信号只需要指示载波索引为网络侧半静态配置的至少一个载波索引中的某一个载波索引即可，从而可以节约节能信号的开销。同理，可以实现节能信号只需要指示上述需要跳过的PDCCH检测周期的个数为上述网络侧配置的个数中的某一个即可，从而可以节约节能信号的开销。
作为一种可选的实施方式，所述多级序列为不存在扰码序列的多级序列，且所述多级序列中每级序列为gold序列，所述节能标识、所述节能区域标识和所述多级序列的级指示信息是gold序列初始相位的函数。
该实施方式中，通过多个gold序列级联得到的多级序列无扰码，这样可以降低复杂度，且还可以携带多种节能信息。

该实施方式中，可以实现通过扰码序列携带所述节能区域标识和所述级指示信息，而基础序列携带节能标识，从而可以实现节能信号消耗过多的资源与功耗，以达到节约传输资源和功耗的效果。
可选的，在所述多级序列的扰码序列携带所述节能区域标识和所述级指示信息的情况下，所述多级序列中每级序列的扰码序列不同，且同一级内的多个序列的扰码序列相同；或者
在所述多级序列中后一级序列的扰码序列携带前一级或者前多级序列的级指示信息的情况下，所述多级序列中每级序列的扰码序列不同。
进一步的，所述多级序列至少可以包括可第一级序列和第二级序列；
其中，所述第一级序列和所述第二级序列的基础序列可以为同一类型的序列，所述同一类型的序列为正交序列、gold序列、ZC序列位或者Kasami序列；或者

例如：如图4所示：基础序列(Base seq)1至基础序列(Base seq)M1叠加，并与扰码序列(Scrambling sequence)进行扰码操作(例如：相乘)，再进行分割以生成至少一个子序列(Sub sequence generation)，之后，进行子载波映射(Sub-carrier mapping)、IFFT操作、添加循环前缀(Cyclic Prefix，CP)，最后映射到相应的符号(Symbol)上传输，即得到第一级序列(例如：WUS1)；
基础序列(Base seq)M1+1至基础序列(Base seq)M叠加，并与扰码序列(Scrambling sequence)进行扰码操作(例如：相乘)，再进行分割以生成至少一个子序列(Sub sequence generation)，之后，进行子载波映射(Sub-carrier mapping)、IFFT操作、添加循环前缀(Cyclic Prefix，CP)，最后映射到相应 的符号(Symbol)上传输，即得到第二级序列(例如：WUS2)。
在图4所示的方案中，扰码序列携带wake up area ID和多级序列的级指示信息，而多级基础序列指示wake up ID。且每一级扰码序列不同，但是每一级内多个序列的扰码序列相同。基础序列较佳为正交序列或者ZC,gold序列。
又例如：如图5所示：基础序列(Base seq)1至基础序列(Base seq)M1叠加，并与扰码序列(Scrambling sequence)进行扰码操作(例如：相乘)，再进行分割以生成至少一个子序列(Sub sequence generation)，之后，进行子载波映射(Sub-carrier mapping)、IFFT操作、添加循环前缀(Cyclic Prefix，CP)，最后映射到相应的符号(Symbol)上传输，即得到第一级序列(例如：WUS1)；
基础序列(Base seq)M1+1至基础序列(Base seq)M分别与扰码序列(Scrambling sequence)进行扰码操作(例如：相乘)，之后叠加，再进行分割以生成至少一个子序列(Sub sequence generation)，之后，进行子载波映射(Sub-carrier mapping)、IFFT操作、添加循环前缀(Cyclic Prefix，CP)，最后映射到相应的符号(Symbol)上传输，即得到第二级序列(例如：WUS2)。
在图5所示的方案，扰码序列携带wake up area ID和前一级或者多级序列的与wake ID相关的信息；多级基础序列指示wake up ID。且每一级扰码序列不同，可选的，第一级内多个序列的扰码序列可以相同，而其它级内多个序列扰码序列可以不同。一种方案中，每级序列为gold，例如：针对两级序列为gold+gold；另一种方案中，每级序列为Hadarmad序列(简称H)，例如：针对两级序列为H+H；另一种方案中，第一级序列为H，第二级序列为gold序列(简称g)，即可以表示H+g，当然，这里仅是举例，具体可以可支持根据网络侧设备指示各级采用的序列。
作为一种可选的实施方式，所述节能信号携带多种节能信息构成的二元指示信息与所述多级序列的序列索引(sequence index)对应；其中，所述多种节能信息至少包括所述节能标识、所述节能区域标识和所述多级序列的级指示信息。
其中，上述节能信号携带多种节能信息构成的二元指示信息与所述多级序列的序列索引对应可以是，节能信号携带的多种节能信息构成的二元指示 信息的十进制表达与多级序列的序列索引对应。
另外，上述对应可以是，上述多级序列的序列索引可以表示上述节能信号携带多种节能信息构成的二元指示信息，或者上述对应可以是节能信号携带的多种节能信息构成的二元指示信息的十进制表达与多级序列的序列索引一一对应。
可选的，上述多级序列的序列索引不同的字段对应不同的节能信息。这样可以通过不同的字段确定不同的节能信息。
一个简单例子，如下表所示：
Figure PCTCN2019124796-appb-000001
其中，五个字段构成n1+n2+n3+n4+n5个比特对应多级序列的序列索引为2 (n1+n2+n3+n4+n5)。
需要说明的是，上述Wake up ID相关信息可以是用于指示Wake up ID，另外，本公开实施例中，Wake up ID可以通过多级序列组合指示，例如：第一级序列携带Wake up ID的部分信息，第二级序列携带该Wake up ID的另部分信息，当然，也可以通过某一级序列单独指示，例如：第一级序列携带一些Wake up ID的全部信息，对此不作限定。
需要指出的上述五个字段的节能信息只是一个例子，不排除有更多或者更少的信息，如与传输节能信号的资源相关的时间或者频率信息，上述表格中多个字段的排序方式也只是个示例，不排除多个字段的其它顺序，比如wake up ID相关信息可以如表格所示位于指最高有效位(Most Significant Bit，MSB)也可以位于最低有效位(Least Significant Bit，LSB)。
作为一种可选的实施方式，在所述多级序列包括第一级序列和第二级序列的情况下，所述终端检测到所述第一级序列的情况下，才执行所述第二级序列的检测。
该实施方式中，由于终端检测到所述第一级序列的情况下，才执行所述第二级序列的检测，这样可以避免终端在没有检测到第一级序列的情况下， 进行第二级序列的检测而产生的功耗浪费。
作为一种可选的实施方式，所述第一级节能信号携带不需要盲检的节能信息；
所述第二级节能信号至少携带无法提前预知的节能信息。
其中，上述不需要盲检的节能信息可以是终端不通过盲检测能够检测到的节能信息，另外，上述不需要盲检的节能信息也可以是对于终端来说是已知的节能信息，例如：wake up ID、wake up area ID、序列级的指示信息(如果是多级序列)。
而上述无法提前预知的节能信息可以是对于终端来说是未知的节能信息，例如：BWP index、Carrier index、需要skip掉的PDCCH检测周期的个数N_skip、传输节能信号的资源信息。
该实施方式中，由于第一级节能信号携带不需要盲检的节能信息，从而可以低能耗地唤醒终端，而第二级节能信号至少携带无法提前预知的节能信息，这样可以实现这两级节能信号携带大量的节能信息，以提高节能效果。
可选的，所述第一级节能信号在非连续接收睡眠DRX OFF周期内传输所述第二级节能信号在DRX OFF或者非连续接收激活DRX On周期内传输。
该实施方式中，可以实现第一级节能信号在DRX OFF周期内唤醒终端，而第二级节能信号在DRX OFF或者DRX On周期内传输，以传输至少携带无法提前预知的节能信息。
例如：如图6所示，第一级节能信号DRX OFF周期内传输，第二级节能信号在DRX OFF周期内传输；其中，附图中以Stage 1 WUS表示第一级节能信号，以Stage 2 WUS表示第二级节能信号.
或者如图7所示，第一级节能信号DRX OFF周期内传输，第二级节能信号在DRX ON周期内传输。其中，附图中以基于序列的WUS(sequence based WUS)表示第一级节能信号，以Stage 2 WUS表示第二级节能信号。
可选的，所述DRX On周期内发送所述第二级节能信号的候选位置可以为半静态配置，或者所述网络侧设备与所述终端预先约定。可选的，第二级节能信号在DRX ON周期内起始位置传输。
可选的，所述第一级节能信号为单级序列或者多级序列；和/或
所述第二级节能信号为基于物理下行控制信道PDCCH的节能信号。
其中，上述第一级节能信号为单级序列或者多级序列可以是基于序列的单级序列或者多级序列，即第一级节能信号可以称作sequence based power saving信号。且该多级序列可以参见本公开实施例上面描述的多级序列，此处不作赘述。
而上述第二级节能信号为PDCCH的节能信号可以称作PDCCH based power saving信号，或者称作DCI based power saving信号。
需要说明的是，本公开实施例提供的上述多种可选的实施方式可以单独实现，也可以相互结合实现，下面以多级序列为两级序列对本公开实施例提供的节能信号的传输方法进行举例说明：
实施例1：
一种基于多级序列的power saving信号例子图3所示，为叙述简单期间，假定为两级序列构成的power saving信号。第一级序列生成方式如下：基站侧频域序列：序列1,序列2，序列3，…序列M1相累加，然后对和序列进行IFFT与添加CP操作映射为时域的m1个OFDM符号，得到第一级序列；第二级序列生成方式与第一级生成方式是类似的，频域序列M1+1,序列M1+2，序列M1+3，…序列M相累加，然后对和序列进行IFFT和添加CP操作映射时域的m-m1个OFDM符号，得到第二级序列，两级序列共同构成power saving信号。图中OFDM符号索引的最小值是1且为连续的，只是个例子，OFDM符号索引起点可以是满足要求的任何值，OFDM符号索引可以分布式的，即不存在连续关系，OFDM符号个数m可以等于1，此时该两级序列实际上是频分序列；图中所示的两级序列只是为了描述方便而给出的具体例子，对3级及以上的多级序列原理一致，都属于本公开保护的内容。频域序列1，2，…M皆为伪随机序列，如常用的m序列及其gold序列或者Kasami序列。如前所述考虑到power saving信号需要携带较多的信息，较佳的，频域序列1，2，…M皆为gold序列或者Kasami序列。
一个具体例子，可以采用NR标准用于下行参考信号的寄存器长为31的gold序列c(n)，定义如下：
c(n)＝(x 1(n+N C)+x 2(n+N C))mod2
x 1(n+31)＝(x 1(n+3)+x 1(n))mod2
x 2(n+31)＝(x 2(n+3)+x 2(n+2)+x 2(n+1)+x 2(n))mod2
其中，标准中定义可以为N C＝1600，该值也可以是预先约定的其它值，NR标准中第一个序列x 1(n)初始化为x 1(0)＝1,x 1(n)＝0,n＝1,2,...,30。第二个序列x 2(n),初始化为
Figure PCTCN2019124796-appb-000002
取决于具体用途。通过上述可知gold序列实际上由两个m序列在二元域对应相累加得到，对于NR采用的寄存器长为31的gold序列，除去全零序列，共有2 31-1个不同的初始相位，对应2 31-1个不同的gold序列。所以该gold序列最多可以携带31比特信息，由于实际中所采用的gold序列长度无法达到2 31-1，所以实际中所携带的信息比特个数一般要小于31，这也与具体序列取多长有一定关系。假定gold序列携带的信息比特个数为InforNum<31。
本公开实施例中，将前面所述的需要power saving信号指示的多种信息分别用多级序列携带，首先UE specific的power saving信号必须携带wake up area ID与wake up ID相关信息(也可以称作wake up ID)。是为了避免在相同的资源上错误的唤醒其它级序列对应的wake up ID，比如时隙1，有用户1的两级序列的第一级序列与用户2的两级序列的第二级序列同时发送，用户1可能将用户2的序列检测为自己的序列。必选的多级序列中需要携带区分多级序列的不同级的指示信息，具体方案可以如下：
方案1：每一级序列都需要携带多级序列的级指示信息，以本实施例中两级序列为例，第一级gold序列初始相位需要包含1比特的stage index信息，如比特0，第二级gold序列初始相位同样包含1比特初始相位信息，如比特1，如果更多级的序列，指示stage index的比特数自然增加。更具体的，比如power saving信息携带最多信息比特个数为InforNum＝24，第一级(gold)序列初始相位可携带wake up area ID相关信息(也可以称作wake up area ID)占10比特与wake up ID相关信息占8个比特，第一级序列的stage index信息(占1个比特)；第二级gold序列初始相位可携带wake up area ID相关信息(占10比特)，第二级序列的stage index信息(占1个比特)，第二级序列携带的wake up ID相关信息(占8比特)，两级序列最多支持256*256个wake up  ID信息。需要注意的是每一序列中携带的与wake up ID相关信息可以是完整的wake up ID信息，也可以是部分wake up ID信息。
方案2：后一级(gold)序列需要携带前一级或者多级(gold)序列携带的与wake up ID相关信息，例如以两级序列为例，第一级gold序列中的每个特定的序列都携带与特定wake up ID相关的信息，如果将第一级序列所有的可能的序列视为一组序列，可以将该组序列再进行分组得到S个子组，每个子组的index(即分组索引信息)可以作为一种与wake up ID相关的信息。第二级gold序列需要携带与第一级序列中与wake up ID相关的信息(例如：分组索引信息)，该信息可以是第二级gold序列的初始相位的函数。由于对第一级序列进行了分组，将子组index传给了第二级序列，子分组数S值最小可以取1，S值最大可与该级序列中所有序列个数一样多，即每个子分组中序列个数只有1；当S值取1时，等价于第一级序列中没有多级序列的级index，而第二级多级序列中包含一个公共的(例如1比特)比特的第一级序列的级index，这是方案1，各级序列携带级index的一个特例。显然S值越大越有利于降低序列检测的虚警概率，当然S值越小则越有利于提高特殊序列如正交序列的多用户复用性能。
多级序列除了要携带wake up area ID，wake up ID，级指示信息外，还可以携带BWP index、Carrier index和传输power saving信号的资源相关的时间或者频率信息中的一种或者多种。例如：仍假定InforNum＝24,第一级(gold)序列初始相位可携带wake up area ID(占10比特)与wake up ID相关信息(占7个比特)，stage指示信息(1个比特)，BWP index相关信息(占2个比特),Carrier index相关信息(占4个比特)；第二级序列携带wake up area ID(占10比特)，wake up ID相关信息(占9比特)，级指示信息(1个比特)，两级序列共支持2^16个wake up ID，可激活15个载波，切换4个BWP，skip掉4种可能的PDCCH检测周期。
终端只有检测出第一级序列才会检测第二级序列，如果第一级序列检测失败就不再检测第二级序列。终端只要检测出第一级序列就会执行wake up过程，即在后续的DRX ON周期内执行PDCCH检测，以降低漏检概率。
上述例子中的多级序列较佳的基于gold序列得到，但并不排除可能是其 它PN序列，如与gold序列性能非常接近的Kasami序列，当然也可以是多级序列分别采用不同的序列，如一级序列采用gold序列，另一级序列采用Kasami序列。
实施例2：
实施例1中的多级序列，由于gold序列或者Kasami序列输入参数可以携带多个比特，故每一级序列可都基于gold序列或者Kasami序列得到。但是gold序列或者Kasami序列在相同资源上复用的用户数较多时，性能会因为相互间干扰变大，而变差。所以可以基于正交序列考虑power saving信号。而且无扰码的序列只有gold序列的寄存器很长时采适用。下面叙述有扰码序列时如何支持，多级序列携带多种信息。
还是以two-stage的power saving序列为例，
方案1：如图4所示。两级WUS序列构成一个power saving信号，产生原理相同，每一级WUS生成方式都是先对频域基本序列进行叠加，然后对和序列扰码，然后进行IFFT等操作转换到时域m个符号，m可以等于1此时多级序列为频域级联。其中多级基础序列对应wake up ID信息，而扰码序列对应wake up area ID信息，较佳的基础序列可以是正交序列如Hadamard/wash序列/ZC序列的循环移位等，扰码序列较佳的为gold序列，如实施例1中NR采用的31阶寄存器的gold序列。例如第一级WUS最多支持M1＝256个序列，第二级WUS也最多支持M1＝256个序列，则两级WUS序列级联后可以得到M1*M1个序列，同一个wake up area内的这M1*M1个序列都采用相同的扰码序列与wake up area ID信息相对应，power saving信号的扰码序列除了携带wake up area ID还需要携带多级序列的不同级的指示信息，扰码序列至少是wake up area ID还需要携带多级序列的不同级的指示信息的函数，多级序列每一级的扰码序列不一致。
方案2：如图5所示。两级WUS序列构成一个power saving信号，产生方式如下：第一级序列产生方式为：频域基础序列1,基础序列2，基础序列3，…基础序列M1相累加，然后对和序列利用一个公共扰码序列进行扰码，然后对和序列进行子载波映射IFFT与添加CP操作映射为时域的m1个OFDM符号，得到第一级序列；第二级序列与第一级产生方法不一致，具体 为：每个频域基础序列先进行独立的扰码操作，扰码序列与第一级序列的分组的组index相关，然后将扰码后的M-M1个序列相加，第二级序列每个基础序列的扰码间相互独立，然后对和序列进行子载波映射IFFT与添加CP操作映射时域的m-m1个OFDM符号。注意m1可以等于1,此时多级序列为频分复用。
上述结构的power saving信号必须携带wake up area ID，wake up ID，而且后一级序列需要携带前一级或者多级序列的与wake up ID相关的信息(例如：分组索引信息)，所述的前一级或者多级序列的与wake up ID相关的信息的定义与实施例1方案2的相关描述类似。如果将第一级序列所有的可能的序列视为一组序列，可以将该组序列再进行分组得到S个子组，每个子组的index可以作为一种与wake up ID相关的信息。本公开对前一级序列可能的序列进行了分组，将子组index传给了第二个级序列，即在第二级序列的扰码序列中携带第一级序列的组index信息，S值最小可以取1，S值最大可与该级序列中所有序列个数一样多，即每个子分组中序列个数只有1，当S值取1时，这等价于第一级序列的扰码序列中没有多级序列的级index，而第二级多级序列的扰码序列中包含一个公共的如1比特的级index，这便是方案1中的一个特例。显然S值越大越有利于降低序列检测的虚警概率，S值越小则越有利于提高特殊序列如正交序列的多用户复用性能。
上述描述中，两级基础序列构成的序列组合对应wake up ID信息，wake up area ID信息由扰码序列携带。第一级序列采用的一个公共扰码序列来携带wake up area ID信息，而第二级序列的扰码序列除了携带wake up area ID信息还要携带前一级序列的组index信息，所谓携带，较佳的指需要携带的信息是扰码序列的函数。基础序列可以是正交序列如Hadamard/wash序列/ZC序列的循环移位或者gold序列或者不同根的ZC序列等，扰码序列较佳的为gold序列，如实施例1中NR采用的31阶寄存器的gold序列。
更具体的有如下方案：
方案1：第一级序列的基础序列，与第二级基础序列都为gold序列或者Kasami序列，而扰码序列仍然为长gold序列，如前面所述的寄存器长为31的gold序列c(n)。更具体的第一级基础序列与第二级基础序列取NR中的SSS 序列。SSS序列有1008个序列，两级SSS序列有1008*1008＝1016064个序列组合，可以支持最多1016064个用户，携带接近20比特的信息。由于两级序列为SSS+SSS,UE可以利用SSS序列进行时频同步，注意到SSS序列有扰码存在所以不会与legacy SSB(同步信号block)发生混淆。该方案两级序列都为gold序列优点支持的用户数多，缺点是多序列叠加时如果用户数特别多，性能会损失严重。
方案2：第一级序列的基础序列，与第二级基础序列都为正交序列或者ZC序列，而扰码序列仍然为长gold序列，如前面所述的寄存器长为31的gold序列c(n)。更具体的例如第一级基础序列取Hadarmad序列，第二级基础序列同样取Hadarmad。假定单级序列长度为128，两级SSS序列有128*128个序列组合，所以支持的用户远少于SSS+SSS，但该方案的第一级序列为正交序列，而且由于第二级序列的子组。
方案3：第一级基础序列都为正交序列或者ZC序列，第二级基础序列都为gold序列或者Kasami序列，而扰码序列仍然为长gold序列，如前面所述的寄存器长为31的gold序列c(n)。更具体的第一级基础序列取Hadarmad或ZC序列，第二级基础序列取gold序列如SSS序列。假定单级序列长度为128，两级SSS序列有128*1008个序列组合,所以支持的用户多于两级序列都为正交序列，少于两级序列都为gold序列，但性能优于两级序列都为gold序列，与两级序列都为正交序列相仿。假定第一级序列为如Hadarmad的正交序列，第二级序列为gold如SSS序列，还有一个好处在于，基站可以根据应用场景配置power saving信号的级数，比如用户数较少的场景，可以只配置第一级序列全为正交序列，多用户叠加的性能会大大提高，如果用户数很多可以配置两级信号。基站动作是，有一个RRC携带的半静态信令或者系统信息指示所采用的power saving信号的级index,当然也可以是DCI或者MAC CE等动态信令。
Power saving信号除了要携带wake up area ID，wake up ID，前一级或者多级序列的wake up ID，有时还需要携带其他power saving信息，则可以采用如下方案。
power saving信号携带的多种power saving信息构成的二元指示信息(的 十进制表达)与多级序列的序列索引(sequence index)一一对应。一个简单例子，如下表所示
Figure PCTCN2019124796-appb-000003
五个字段构成n1+n2+n3+n4+n5个比特对应多级序列的序列index为2 (n1+n2+n3+n4+n5)
需要指出的上述四个字段的power saving信息只是一个例子，不排除有更多或者更少的信息，如与传输power saving信号的资源相关的时间或者频率信息，上述表格中多个字段的排序方式也只是个示例，不排除多个字段的其它顺序，比如wake up ID相关信息可以如表格所示位于MSB也可以位于LSB。
上述方案可以解决多级序列中所包含的序列组合如何携带power saving信息。如前所述该扰码序列至少携带wake up area ID信息，但是注意的是扰码序列为gold或者Kasami序列时，其初始相位除了必须携带wake up area ID信息还可以携带其它的power saving信息，例如gold序列初始相位可以是wake up ID相关信息与BWP index的函数，这样由于BWP index被扰码序列携带，N_MS＝M1*M1个序列可以携带更多的其它信息，比如更多的wake up ID信息，或者更多需要skip的PDCCH检测周期的个数的信息；扰码序列也可以是power saving信号所处的时间或者频率信息的函数，例如初始相位与power saving信号发送起点的slot index或者power saving信号发送频率配置的index相关，如这些power saving信息可以作为初始相位的输入。
而终端行为可以是：wake up area对终端来说是已知的。终端首先在对应位置上接收power saving信号，终端首先执行解扰码操作，将去扰码后的接收信号与自己已知的对应的基础序列执行相关性检测，从而确定该资源上是否存在对应的power saving信号。需要指出的是对于无法预先已知的power saving信息，如BWP index没有先验信息是未知的，终端需要根据BWP index可能的值执行盲检或者假设检验。如果终端检测到对应的power saving信号 则执行wake up在后续DRX ON内执行PDCCH检测，否则继续睡眠。
实施例3：
实施例1与2所述的方法可以实现power saving携带除了wake up area ID与wake up ID外的其它多种power saving信息。但是如果其携带的信息如果是未知的比如BWP index信息，如果BWP index是未知的则终端则需要对BWP index进行盲检或者假设检验。这无疑会增大UE检测功耗。另外一种方法如下：
网络侧设备在DRX OFF内首先发送基于序列的power saving信号，比如实施例1与2所示的多级序列，也可以是实例2所述基于正交序列的多级序列中的一级序列，即单级序列，基于序列的power saving信号较佳的只携带不需要盲检的power saving信息，比如wake up ID,wake up area ID，多级序列的级指示信息(如果是多级序列)，节能信道(power saving channel)相关的已知信息，如果网络侧设备发送了唤醒某个wake up ID的第一级power saving信号，基站会在针对该wake up ID在DRX OFF周期内发送基于PDCCH的节能信号(PDCCH based power saving信号)，即在DRX OFF内发送一个PDCCH其DCI携带了UE无法提前预知的前面所述的power saving信息，如BWP index，如图6所示。该PDCCH based power saving信号发送频域位置可以与基于序列的节能信号(sequence based power saving信号)相同，较佳可以与DRX ON内PDCCH配置的频域资源相同。
而图7表示第二级DCI based power saving信号在DRX ON内发送的例子，与图6相同，第一级sequence based power saving信号在DRX OFF内发送用于唤醒终端，PDCCH based power saving信号携带多种前面所述的power saving信息在DRX ON内，且较佳的在DRX ON初期发送，如在DRX ON周期的前L个slot内发送(例如L小于等于确定值如8)，由于是在DRX on内，为了避免盲检PDCCH，可以提前预定或者由基站通过RRC信令半静态配置一个或者多个发送第二级PDCCH based power saving信号的候选发送位置，UE在相应位置检测第二级PDCCH based power saving信号。其中第二级PDCCH based power saving信号与相关技术中的PDCCH的区别在于，其携带了一个特殊定义的DCI用于承载power saving信息。
