为了便于更好地理解本申请实施例，下面先介绍以下技术点。
(1)正交频分复用(Orthogonal frequency division multiplex，OFDM)信号帧结构
移动通信系统中，如第5代(5th Generation，5G)NR和第4代(4th Generation，4G)LTE中，时域上的最小时间单元为一个OFDM符号，一个时隙包含14个OFDM符号，每个OFDM符号开始包含一个循环前缀(Cyclic prefix，CP)，其中循环前缀是通过截取一个OFDM符号末尾部分长度复制得到的，根据子载波间隔(SCS)不同，每个OFDM符号的长度不同，例如在子载波间隔为15kHz时，一个OFDM符号除CP以外的长度为2048Ts，除第一个OFDM符号外其它OFDM符号包含的CP长度为144Ts，第一个OFDM符号包含的CP长度为160Ts，其中，
Ts＝1/(Δfref·Nf,ref)＝1/(15·103·2048)＝0.033μs。
Δfref为子载波间隔，Nf,ref为一个OFDM符号除CP以外的长度。
不同子载波间隔下的一个OFDM符号长度及正常CP长度请见表1。一个OFDM信号时隙，OFDM符号，及循环前缀的说明如图2所示。
表1
(2)802.11ba唤醒信号时域结构
802.11ba中，唤醒信号的物理层数据单元(physical layer protocal data unit，PPDU)如图3所示，其中前五个域用以实现与802.11已有用户共存，不具备低功耗唤醒功能，802.11ba接收机不对其译码，后两个域分别为低功耗唤醒信号的同步域和数据域，同步域包含两种长度的序列：64us和128us，分别指示数据域的两种数据率：62.5kbs和250kbs。其中同步域和数据域低速率采用长度为2us的OOK符号发送，数据域高速率采用长度为4us的OOK符号发送。2us和4us的OOK符号均通过复用802.11OFDM信号的生成结构生成，如图4和图5所示。图4中，通过确定合适的子载波系数，进行离散傅里叶逆变换 (Inverse Discrete Fourier Transform，IDFT)，得到3.2us的时域符号，仅保留第一半的1.6us，符号随机化后，截取结尾的0.4us信号作为循环前缀，得到2us开关键控(On-Off Keying，OOK)符号。图5中，通过确定合适的子载波系数，进行IDFT，得到3.2us的时域符号，符号随机化后，截取结尾的0.8us信号作为循环前缀，得到2us OOK符号。802.11OFDM符号长度为4us，因此可直接复用4us的OFDM信号生成结构得到2us和4us的OOK符号。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的信息确定方法、装置及终端进行详细地说明。
参见图6，图6是本申请实施例提供的一种信息确定方法的流程图，如图6所示，信息确定方法包括以下步骤：
步骤101、终端获取第一信息；
步骤102、所述终端基于所述第一信息确定低功耗信号中的第一序列的时域资源映射信息；
其中，所述时域资源映射信息用于指示：所述第一序列在所述低功耗信号的时域资源上映射的映射方式，所述低功耗信号的时域资源包括多个符号资源，所述多个符号资源中每个符号资源包括附加时间资源和至少一个第一符号。
其中，时域资源映射信息可以用于指示：所述第一序列在所述低功耗信号的时域资源上映射的映射方式。低功耗信号的时域资源可以包括多个符号资源，所述多个符号资源中每个符号资源包括附加时间资源和至少一个第一符号。所述第一信息可以用于指示所述时域资源映射信息；所述第一序列；所述低功耗信号的时域资源长度；所述附加时间资源的长度；所述符号资源的长度；所述第一符号的长度中的至少一项。
一种实施方式中，时域资源映射信息可以用于指示第一序列的时域资源映射方法。该时域资源映射方法可以包括资源映射格式为第一格式，或者资源映射格式为第二格式。在资源映射格式为第一格式时，第一序列在附加时间资源上未映射有用信息；在资源映射格式为第二格式时，第一序列在附加时间资源上映射有用信息。
一种实施方式中，低功耗信号可以由OFDM信号生成结构生成，OFDM信号生成结构生成的信号的信号帧结构的特点为：在时域上，一个时隙包含多个OFDM符号，每个OFDM符号开始包含一个循环前缀，该循环前缀是通过截取一个OFDM符号末尾部分长度复制得到的。对于OFDM信号生成结构生成的低功耗信号，一个OFDM符号中包括多个低功耗信号符号。低功耗信号符号可以为OOK符号，或经过编码后的OOK符号。在该实施方式中，符号资源可以为OFDM符号，第一符号可以为低功耗信号符号。
一种实施方式中，所述低功耗信号包括循环前缀，该循环前缀通过截取一个符号资源包含的最后一个第一符号末尾的部分长度得到，所述附加时间资源为所述循环前缀的时域资源。
另外，第一序列的时域资源映射信息可以用于检测低功耗信号。通过第一序列的时域 资源映射信息，终端可以生成用于序列自相关检验的本地序列，通过该本地序列进行序列自相关检验，可以检测到与该本地序列的序列自相关程度高于预设阈值的序列，与该本地序列的序列自相关程度高于预设阈值的序列为第一序列，从而可以通过该第一序列判断检测到低功耗信号，该预设阈值可以按照实际需求设置。
需要说明的是，终端可以获取第一序列、低功耗信号的时域资源长度、附加时间资源的长度、符号资源的长度及第一符号的长度。通过所述时域资源映射信息、所述第一序列、所述低功耗信号的时域资源长度、所述附加时间资源的长度、所述符号资源的长度及所述第一符号的长度生成用于序列自相关检验的本地序列，通过该本地序列进行序列自相关检验，以检测低功耗信号。
另外，所述第一序列、所述低功耗信号的时域资源长度、所述附加时间资源的长度、所述符号资源的长度及所述第一符号的长度中的一项或多项可以通过第一信息指示，或者可以由网络预先配置，或者可以由协议预定义。本实施例对获取所述第一序列、所述低功耗信号的时域资源长度、所述附加时间资源的长度、所述符号资源的长度及所述第一符号的长度的方式不进行限定。
另外，低功耗信号的时域资源长度可以为L个符号资源的长度，符号资源的长度与附加时间资源的长度的差值可以为M个第一符号的长度，L及M均为正整数。
一种实施方式中，时域资源映射信息可以用于指示第一序列在附加时间资源上未映射有用信息。在第一序列在附加时间资源上未映射有用信息的情况下，所述第一序列在所述低功耗信号的时域资源上映射的映射方式包括：所述第一序列映射至所述低功耗信号的时域资源的第一部分资源，所述第一部分资源包括所述低功耗信号的时域资源包含的全部符号资源中除所述附加时间资源以外的资源。从而在生成用于序列自相关检验的本地序列时，能够依据第一序列的时域映射方式在第一序列的基础上扩展附加时间资源长度的序列，生成本地序列，使得生成的本地序列与第一序列的特征较为匹配，降低了低功耗信号中的循环前缀对序列自相关检验的影响，使得本地序列与第一序列的相关性较强，能够提高终端检测低功耗信号的准确性。
作为一种具体的实施例，时域资源映射信息指示第一序列在附加时间资源上未映射有用信息。第一序列的序列长度为：L*M。终端可以将第一序列按从左到右的顺序分成L个子组，每个子组包含M个序列元素，每个序列元素占用一个第一符号长度，得到L个子组，每个子组映射的时域资源长度为：(符号资源长度-附加时间资源长度)。终端生成本地序列用于自相关检验第一序列时，对于第1个子组至第L个子组，每相邻的两个子组间插入一个附加时间资源长度的信号，信号取值可以均取0，得到用于第一序列自相关检验的本地序列；或者，信号取值可以不为0，对于第1个子组至第L个子组，将第k个子组结尾一个附加时间资源长度的信号复制后插入第k个子组与第k-1个子组间，得到用于第一序列自相关检验的本地序列，k为大于1且小于等于L的整数。
一种实施方式中，时域资源映射信息可以用于指示第一序列在附加时间资源上映射有 用信息。在第一序列在附加时间资源上映射有用信息的情况下，所述第一序列在所述低功耗信号的时域资源上映射的映射方式包括：所述第一序列映射至所述低功耗信号的时域资源的，所述第二部分资源包括所述低功耗信号的时域资源中的全部符号资源。从而在生成用于序列自相关检验的本地序列时，能够考虑循环前缀映射到附加时间资源上的是第一序列的非冗余部分，使得生成的本地序列与第一序列的特征较为匹配，降低了低功耗信号中的循环前缀对序列自相关检验的影响，使得本地序列与第一序列的相关性较强，能够提高终端检测低功耗信号的准确性。
作为一种具体的实施例，时域资源映射信息指示第一序列在附加时间资源上映射有用信息。在符号资源内，附加时间资源长度包含N个第一符号长度时，附加时间资源内映射N个第一序列的序列元素；附加时间资源长度大于N-1个第一符号长度，且小于N个第一符号长度时，附加时间资源内映射N-1个或N个第一序列的序列元素。第一序列的序列长度为：L*M+L*N或L*M+L*(N-1)。终端可以将第一序列按从左到右的顺序分成L个子组，每个子组包含M+N或M+N-1个序列元素，每个子组中前N个或N-1个序列元素占用附加时间资源长度的时间资源，每个子组中后M个序列元素，每个序列元素占用一个第一符号长度的时间资源，L及M均为正整数，N为大于1的正整数。
需要说明的是，第一序列可以映射到低功耗信号的时域资源包含的全部符号资源除去附加时间资源以外的部分；或者，第一序列可以映射到低功耗信号的时域资源包含的全部符号资源。
另外，对于每个符号资源，附加时间资源的起始位置可以是符号资源的起始位置，至少一个第一符号中第一个第一符号的起始位置可以是附加时间资源的结束位置，至少一个第一符号中最后一个第一符号的结束位置可以是符号资源的结束位置。
一种实施方式中，附加时间资源可以为每个符号资源自起始持续附加时间资源长度的部分。
需要说明的是，所述时域资源映射信息用于指示：所述第一序列在所述低功耗信号的时域资源上映射的映射方式，所述低功耗信号的时域资源包括多个符号资源，所述多个符号资源中每个符号资源包括附加时间资源和至少一个第一符号，这样，通过第一序列映射的资源，终端能够确定用于序列自相关检验的本地序列，从而通过本地序列检测低功耗信号中的第一序列，能够通过第一序列确定低功耗信号，从而能够提高终端检测低功耗信号的准确性。
本申请实施例中，通过低功耗信号中的第一序列的时域资源映射信息，能够较为准确地确定第一序列的时域映射方式，依据该时域映射方式进行序列自相关检验，能够提高终端检测低功耗信号的准确性。
需要说明的是，802.11ba采用802.11OFDM信号生成结构得到2us和4us OOK符号。相关技术中，移动蜂窝系统引入低功耗唤醒信号时，同样可以基于LTE或NR发送端的OFDM信号生成结构来生成ASK信号，LTE中的一个OFDM符号为66.67us，NR包含多 种长度的OFDM符号，考虑到灵活支持低功耗接收信号的速率，不适于将低功耗唤醒信号的一个符号长度总是固定为LTE或NR中一个OFDM符号的长度或一半长度，当一个OFDM符号长度包含多于2个低功耗唤醒信号符号长度时，循环前缀容易导致低功耗唤醒信号的符号检测失败。
相关技术中，低功耗信号可复用OFDM信号生成结构生成，在频域生成信号后经傅立叶逆变换到时域得到幅度键控(ASK)信号。其优势在于不额外增加相关技术中的移动通信系统中发送端的复杂度，具有很好的系统兼容性。然而，考虑每个OFDM符号前均带有循环前缀(CP)，当采用OFDM信号生成结构生成低功耗信号时，产生的循环前缀容易导致低功耗信号检测失败。具体地，因采用简化的接收机结构，终端是通过异步通信接收网络侧设备发送的低功耗信号，从而终端仅能通过盲检测的方式检测低功耗信号，从而终端无法确定低功耗信号及循环前缀的时域位置，无法提前将循环前缀去掉，本申请实施例通过低功耗信号中的第一序列的时域资源映射信息，能够较为准确地确定第一序列的时域映射方式，尤其是在附加时间资源上的映射信息，能够提高终端检测低功耗信号的准确性。
本申请实施例中，终端获取第一信息；所述终端基于所述第一信息确定低功耗信号中的第一序列的时域资源映射信息；其中，所述时域资源映射信息用于指示：所述第一序列在所述低功耗信号的时域资源上映射的映射方式，所述低功耗信号的时域资源包括多个符号资源，所述多个符号资源中每个符号资源包括附加时间资源和至少一个第一符号。这样，通过低功耗信号中的第一序列的时域资源映射信息，能够确定第一序列的时域映射方式，在检测低功耗信号时，能够依据确定的时域映射方式进行序列自相关检验，从而能够提高终端检测低功耗信号的准确性

本申请实施例还提供了一种信息确定系统，包括：终端及网络侧设备，所述终端可用于执行如上所述的信息确定方法的步骤。
随着通信技术的发展，在移动通信终端引入低功耗(Low power)唤醒接收机(Wake-up  Receiver，WUR)，通过检测低功耗唤醒信号(wake-up signal，WUS)来触发唤醒主通信模块。由于移动通信终端的链路状态是变化的，当低功耗链路质量较差时，将导致终端检测低功耗唤醒信号失败。对于链路质量检测通常包括以下两种检测方式：
方式1：通过检测一段时间内发送的保持信号的次数确定链路质量；
方式2：基于同步信号块(Synchronization Signal and PBCH block，SSB)进行无线资源管理(Radio resource management，RRM)测量。
针对方式1，在基于竞争接入的通信场景中，由于在没有接收到保持信号时，无法确定是由于网络侧设备没有发送保持信号还是由于链路质量差所导致的，因此确定链路质量的准确性较差。针对方式2，由于是基于频域资源单元确定参考信号接收功率，无法应用到低功耗接收机对参考信号的接收功率进行计算。因此，相关技术中存在低功耗链路的链路质量测量的准确性较差的问题。
本申请实施例还提供一种低功耗信号接收功率测量方法，能够解决低功耗链路的链路质量测量的准确性较差的问题。
为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、WUR信标(beacon)信号。
为保持低功耗WUR与接入点(Access Point，AP)间同步，通常采用周期性发送WUR beacon信号来传递时间信息，WUR beacon媒体接入控制(Medium Access Control，MAC)帧(frame)的类型相关控制(type dependent control)携带AP的时间同步功能(Time Synchronization function，TSF)时钟(timer)64比特中的[5:16]共12比特信息，用户收到该12比特信息后，根据定义的时间更新准则，更新用户本地的TSF timer,从而达到与AP同步的目的。WUR beacon的发送周期和发送起始位置的偏移量由AP发送的操作单元(operation element)指示，周期为两次beacon发送间最少的TSF时间单元数，起始位置为相对于TSF0偏移的TSF时间单元数。当发生载波侦听多址访问(Carrier Sense Multiple Access，CSMA)延迟(deferrals)，WUR beacon在当前周期会延迟发送，但在后续周期仍按WUR beacon的发送周期和发送起始位置确定的位置发送。
WUR beacon信号还用来做链路保持信号，当一段时间没有收到WUR beacon信号时，STA必须进行WUR搜索或切换到主通信模块醒来的模式。当唤醒信号配置DRX周期时，即按照非连续接收(Discontinuous Reception，DRX)周期醒来监听唤醒信号时，唤醒信号也用来做链路保持信号，在未发送唤醒信号的DRX周期，AP可以发送WUR beacon用来做链路保持信号。其中，未接受到链路保持信号的时间通过用户实现来确定。
二、5G NR空闲态RRM测量。
5G终端处于空闲态时，需对服务小区的搜索空间参考信号接收功率(Search Space Reference Signal Received Power，SS-RSRP)和搜索空间参考信号接收质量(Search Space Reference Signal Received Quality，SS-RSRQ)水平进行测量并评估是否满足小区选择S准则，测量频率为每M1*L1个DRX周期至少一次，测量的时域位置位于同步信号块测量 时序配置(SS/PBCH block measurement time configuration，SMTC)窗口内，M1的取值范围见下：若SMTC周期大于20ms且DRX周期小于或等于，则M1等于2，否则M1等于1。
终端根据测量结果判断是否满足小区选择S准则，当存在连续N个DRX周期，终端在服务小区的测量结果均不满足S准则时，终端启动对相邻小区的测量。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的低功耗信号接收功率测量方法进行详细地说明。
参照图12，本申请实施例提供了一种低功耗信号接收功率测量方法，如图12所示，该低功耗信号接收功率测量方法包括：
步骤1201，终端在时间单元集合内接收参考信号；
步骤1202，所述终端根据时间单元集合中每一时间单元上的参考信号的功率，确定第一接收功率；
其中，所述时间单元集合包括至少一个承载所述参考信号的时间单元。
本申请实施例中，上述参考信号可以为低功耗信号，也可以为低功耗信号的一部分信号，当参考信号为目标低功耗信号的一部分信号时，低功耗信号的另一部分信号可以包括序列和/或数据。在一些实施例中，参考信号至少包括低功耗信号的一个或多个序列，以使所述终端可以基于序列检测到所述参考信号，从而确定在每一所述时间单元上的参考信号的功率。
可选地，在一些实施例中，上述时间单元集合包括在时域上连续的至少两个所述时间单元。
可选地，所述时间单元集合所包含的时间单元的长度和/或所述时间单元集合所包含的时间单元的数量由网络设备配置或协议约定。
可选地，所述时间单元集合的长度可以由网络设备配置或协议约定。
其中，时间单元的时间长度的单位可以为微秒(us)、毫秒(ms)、秒(s)或正交频分复用(Orthogonal frequency division multiplex，OFDM)符号。
可选地，在检测到参考信号时，可以确定承载参考信号的时间单元集合，也可以在检测参考信号之前获取时间单元集合。然后可以检测获得在时间单元集合中每一时间单元上的参考信号的功率，并基于在每一所述时间单元的参考信号的功率，确定所述第一接收功率。其中，基于一个所述时间单元集合确定的所述第一接收功率可以理解为一次参考信号的测量获得的接收功率。也就是说所述第一接收功率可以表示基于一个所述时间单元集合执行一次测量得到的接收功率。这样基于至少一个时间单元上参考信号的接收功率来确定第一接收功率，根据第一接收功率确定链路质量，无需借助快速傅立叶变换(Fast Fourier Transform，FFT)模块即可实现链路质量测量，也即仅需要低功耗接收机就可进行链路质量测量，而无需唤醒主接收机。
需要说明的是，终端可以根据参考信号的第一接收功率确定低功耗链路质量，当低功 耗链路质量不满足预设条件(即不满足需求)时，表示终端无法解调低功耗唤醒信号，此时基于低功耗链路质量触发唤醒主通信接收机，可以有效保证通信的可靠性。当低功耗链路质量满足预设条件时，终端可以正确检测并解调低功耗唤醒信号，从而可以根据低功耗唤醒信号触发唤醒通信接收机，以降低终端的电能损耗。
本申请实施例，通过终端在时间单元集合内接收参考信号；所述终端根据时间单元集合中每一时间单元上的参考信号的功率，确定第一接收功率；其中，所述时间单元集合包括至少一个承载所述参考信号的时间单元。由于接收功率与低功耗链路质量具有对应关系，因此，本申请实施例可以基于参考信号的接收功率确定低功耗链路质量，提高了低功耗链路质量测量的准确性。
可选地，在一些实施例中，所述终端根据时间单元集合中每一时间单元上的参考信号的功率，确定第一接收功率包括：
所述终端根据所述时间单元集合中每一时间单元上的参考信号的功率，对所述时间单元集合内所有时间单元上的参考信号的功率进行线性平均，得到所述第一接收功率。
本申请实施例中，可以首先计算所有时间单元上的参考信号的功率分布和值，然后基于该和值除以时间单元的数量，从而得到所述第一接收功率，即一次参考信号测量的接收功率。当然在其他实施例中，还可以采用其他计算方式，在此不做进一步地限定。
可选地，在一些实施例中，所述终端根据时间单元集合中每一时间单元上的参考信号的功率，确定第一接收功率之前，所述方法包括以下任一项：
所述终端确定所述时间单元集合的起始时域位置和结束时域位置；
所述终端确定所述时间单元集合的起始时域位置和长度；
所述终端确定所述时间单元集合的结束时域位置和长度。
本申请实施例中，上述所述时间单元集合的长度可以基于时间单元集合包含的时间单元的数量和时间单元的长度确定。
可选地，在一些实施例中，所述参考信号的时间单元集合的起始时域位置和/或结束时域位置通过在时域进行序列检测确定。
也就是说，在本申请实施例中，终端可以在时域进行序列检测，从而确定上述参考信号的时域位置，以得到时间单元集合。
可选地，在一些实施例中，所述参考信号所包含的序列和/或所述参考信号的频域资源位置由网络侧设备配置或协议约定。
可选地，在一些实施例中，所述低功耗信号包括以下任一项：低功耗信标信号和低功耗唤醒信号。
