图1为本申请实施例提供的应用场景示意图。请参见图1,包括终端设备101以及网络设备102。
其中,终端设备101也可以称为用户设备(User Equipment,UE)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置等。终端设备101具体可以是一种向用户提供语音/数据连通性的设备,例如,具有 无线连接功能的手持式设备、车载设备等。具体可以为:手机(Mobile Phone)、平板电脑(Pad)、带无线收发功能的电脑(如笔记本电脑、掌上电脑等)、移动互联网设备(Mobile Internet Device,MID)、虚拟现实(Virtual Reality,VR)设备、增强现实(Augmented Reality,AR)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、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、个人数字助理(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、可穿戴设备,第五代移动通信技术5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,PLMN)中的终端设备等。
其中,可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
此外,终端设备101还可以是物联网(Internet of Things,IoT)系统中的终端设备。IoT是未来信息技术发展的重要组成部分,其主要技术特点是将物品通过通信技术与网络连接,从而实现人机互连,物物互连的智能化网络。IoT技术可以通过例如窄带(Narrow Band,NB)技术,做到海量连接,深度覆盖,终端省电。
此外,终端设备101还可以包括智能打印机、火车探测器、加油站等传感器,主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据,并发送电磁波,向网络设备传输上行数据。本申请实施 例对于终端设备101的具体种类或者名称不作限定。
网络设备102可以是任意一种具有无线收发功能的设备。该设备包括但不限于:演进型节点B(evolved Node B,eNB)、无线网络控制器(Radio Network Controller,RNC)、节点B(Node B,NB)、基站控制器(Base Station Controller,BSC)、基站收发台(Base Transceiver Station,BTS)、家庭基站(例如,Home Evolved NodeB,或Home Node B,HNB)、基带单元(Baseband Unit,BBU),无线保真(Wireless Fidelity,WiFi)系统中的接入点(Access Point,AP)、无线中继节点、无线回传节点、传输点(Transmission Point,TP)或者发送接收点(Transmission and Reception Point,TRP)等。还可以为5G,如,新空口(New Radio,NR)系统中的gNB,或,传输点(TRP或TP),5G系统中的基站的一个或一组(包括多个天线面板)天线面板,或者,还可以为构成gNB或传输点的网络节点,如基带单元(BBU),或,分布式单元(Distributed Unit,DU)等。
在一些部署中,gNB可以包括集中式单元(Centralized Unit,CU)和DU。gNB还可以包括有源天线单元(Active Antenna Unit,AAU)。CU实现gNB的部分功能,DU实现gNB的部分功能。比如,CU负责处理非实时协议和服务,实现无线资源控制(Radio Resource Control,RRC),分组数据汇聚层协议(Packet Data Convergence Protocol,PDCP)层的功能。DU负责处理物理层协议和实时服务,实现无线链路控制(Radio Link Control,RLC)层、介质接入控制(Medium Access Control,MAC)层和物理(Physical,PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息,或者,由PHY层的信息转变而来,因而,在这种架构下,高层信令,如RRC层信令,也可以认为是由DU发送的,或者,由DU+AAU发送的。可以理解的是,网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外,可以将CU划分为接入网(Radio Access Network,RAN)中的网络设备,也可以将CU划分为核心网(Core Network,CN)中的网络设备。本申请实施例对于网络设备102的具体种类或者名称也不做限定。
在通信技术中,为了实现终端设备的节能,在某些场景或时刻,终端 设备可以仅打开独立于主无线电的低功耗唤醒信号接收机(Low Power Wakeup Signal Receiver,LP-WUS或者LP-WUR)。这样,终端设备既可以关闭主无线电,又可以通过低功耗唤醒信号接收机监听低功耗唤醒信号来被网络唤醒,达到网络可达的目的。主无线电(Main Radio)也可以称为主收发机(Main Transceiver)、整体收发机(Overall Transceiver)或常规收发机(Regular Transceiver)等。主无线电是空闲态、非激活态、连接态共用的收发机。低功耗唤醒信号接收机也可以称为低功耗接收机(Low Power Receiver)、唤醒信号接收机(Wakeup Signal Receiver,WUS receiver)等。低功耗唤醒信号接收机主要用于低功耗唤醒信号的接收。
一般来说,在空闲态(Idle State)或非激活态(Inactive State)下,终端设备需要监听寻呼(Paging)相关的物理下行控制信道(Physical Downlink Control Channel,PDCCH),又称为类型2-PDCCH(Type2-PDCCH)。寻呼相关的PDCCH的无线网络临时标识(Radio Network Temporary Identifier,RNTI)为P-RNTI,使用的下行控制信息(Downlink Control Information,DCI)格式(Format)为DCI format 1-0。当终端设备检测到寻呼相关的PDCCH后,即终端设备用P-RNTI解扰循环冗余校验(Cyclic Redundancy Check,CRC)成功之后,则用户设备解析DCI。DCI内可能有短信息(Short Message),以令终端设备获得告警信息或进行系统信息更新。DCI内也可能有调度信息,以令终端设备接收寻呼相关的物理下行共享信道(Physical Downlink Share Channel,PDSCH),获得寻呼消息,并进一步发起随机接入过程进入连接态(Connected State)。寻呼相关PDCCH的监听时机可以由搜索空间集合(Search Space Set,SSS)配置,再由寻呼时机(Paging Occasion,PO)和寻呼监听时机(Paging Monitoring Occasion,PMO)来确定,其中,PO用于确定寻呼帧(Paging Frame,PF)内的监听时机的起点,PMO为从起点开始的顺序的多个监听时机,PMO和真正发送的同步信号块一对一关联。
另一方面,在空闲态或非激活态下,终端设备需要进行周期性的无线资源管理(Radio Resource Management,RRM)测量(Measurement)。RRM测量包括服务小区(Serving Cell)的测量和邻小区(Neighboring Cell)的测量。邻小区测量一般包括:由网络设备给定频点,终端设备在该频点 上进行小区搜索并测量;或者,网络设备给定频点和物理小区标识(Physical Cell ID,PCI),终端设备在该频点使用该PCI进行小区搜索并测量;或者网络设备不给定频点也不给定PCI,终端设备自主进行小区搜索并测量。邻小区测量又可以分为同频(Intra-Frequency)测量和异频(Inter-Frequency)测量。例如,邻小区的测量对象中的同步信号块跟服务小区的同步信号块的中心频点和子载波间隔一样,那么该测量为同频测量。例如,邻小区的测量对象中的同步信号块跟服务小区的同步信号块的中心频点或子载波间隔不一样,那么该测量为异频测量。在空闲态或非激活态下,用户设备一般需要一个寻呼周期(Paging Cycle)内进行一次服务小区的RRM测量。寻呼周期又称为空闲态-非连续接收周期(Idle State Discontinuous Reception,I-DRX)。
由此可见,在空闲态或非激活态下,监听寻呼相关的PDCCH和进行RRM测量是用户设备主要的工作。
对于监听寻呼相关的PDCCH和进行RRM测量,一般来说,寻呼终端设备从深度睡眠(Deep Sleep)醒来处理3个同步信号块突发(SS/PBCH Block Burst,SS Burst),达到一定的时频同步来监听寻呼相关的PDCCH(并且接收PDSCH,如果正确地接收到PDCCH),并同时进行RRM测量。为此,网络设备可以配置寻呼提前指示(Paging Early Indication,PEI),并且终端设备在寻呼相关的PDCCH前检测寻呼提前指示,如果PEI指示需要监听寻呼相关的PDCCH,则终端设备继续监听寻呼相关的PDCCH。一般来说,PEI在PO之前。当配置有PEI时,终端设备从深度睡眠醒来处理1个同步信号块突发,达到一定的时频同步来检测PEI,如果PEI指示需要监听寻呼相关的PDCCH,则终端设备继续处理2个同步信号块突发,并继续监听寻呼相关的PDCCH,如果PEI指示不需要监听寻呼相关的PDCCH,则终端设备转回深度睡眠。在组寻呼率(Group Paging Rate)为10%下,终端设备需要监听寻呼相关的PDCCH的几率为10%。所以,在10%几率下,终端设备需要处理3个同步信号块突发,并监听寻呼相关的PDCCH,并进行RRM测量;在90%几率下,终端设备只需要处理1个同步信号块突发,并进行RRM测量。这样,在90%几率下,终端设备处理的信号/信道较少,醒来时间较短(从深度睡眠醒来后如果不处理信号 /信道,则处于轻度睡眠(Light Sleep)),功耗较小。因此,通过使用PEI,用户设备能够省电。
上述过程都是主无线电的接收过程。一般来说,终端设备处理同步信号块突发、监听PDCCH都使用主无线电,而主无线电的功耗较大,包括终端设备从深度睡眠醒来的转换功耗(能量)、检测PEI的功耗等。
为了降低主无线电从深度睡眠醒来的转换功耗和检测信号的功耗,终端设备恩可以采用一个独立于主无线电的低功耗接收机来检测低功耗唤醒信号。低功耗唤醒信号的设计既要保证接收机能以低功耗进行接收,又要满足灵敏度需求,或者在较低错误率下的信噪比需求。与非低功耗唤醒信号相比,低功耗唤醒信号能够令低功耗唤醒信号接收机在相同延迟下以较低功耗接收唤醒信号,或者在相同功耗下以较低延迟接收唤醒信号。该低功耗接收机可以有如下两类接收方法:
第一类接收方法是低功耗接收机周期地检测唤醒信号。这种方法下,一次检测唤醒信号的功耗较大,但由于周期较长(低功耗接收机仅需要每个长周期醒来一次进行检测),平均的功耗较低。由于需要周期地醒来进行检测,低功耗接收机需要准确的时间同步。该周期可以称为工作周期(Duty Cycle)或检测周期(Detection Cycle或Detection Periodicity)。
第二类接收方法是低功耗接收机可以一直处于检测唤醒信号的状态(又称为待机(Stand-By)状态)。这种方法下,一次检测唤醒信号的功耗较低,虽然一直在检测,但平均的功耗也较低。由于一直在检测,低功耗接收机不需要准确的时间同步。
一般来说,为了简化低功耗接收机,唤醒信号通常采用开关键控(On Off Keying,OOK)的调制方式。简单来说,OOK调制只有幅度信息,没有频率或相位信息,并且幅度只有高(或1)和低(或0)两个幅度。对于OOK,接收方法可以为包络检波(Envelope Detection),包络检波可以直接将接收信号的幅度累积起来,由于其简单性,其所需的功耗也较低。
对于多音(multi-tone)或多载波(multi-carrier)波形下的OOK,一个OOK符号可以为一个多音或多载波的时域符号,如正交频分复用(Orthogonal Frequency Division Multiplexing,OFDM)时域符号,即OFDM符号。对于多音或多载波波形下的OOK,在发射端,一个OOK符号可以 映射到多个子载波。该多个子载波可以跟其他信号/信道的子载波共同组成一个OFDM符号中的所有子载波,这样低功耗唤醒信号可以跟其他信号信道共存于一个OFDM符号。
当然,也可以将多个OOK符号映射到一个OFDM符号,一般有两种方式。一种方式是采用序列的方式,即将多个具有较高子载波间隔的OFDM符号(较短持续时间的OFDM符号)放置在一个OFDM符号内。其中,对于高(或1)幅度的OOK符号,序列1(如Zadoff-Chu序列,简称ZC序列)映射到较高子载波间隔的OFDM符号的多个子载波;对于低(或0)幅度的OOK符号,序列0(如全零序列)映射到较高子载波间隔的OFDM符号的多个子载波。另一种方式是基于预编码的方式,或称为基于波形成形(Shaping)的方式,即将一个OFDM符号对应的所有OOK符号通过预编码(如DFT预编码、基于拟逆的预编码)操作,再将输出映射到到整个OFDM的子载波中。
在接收端(低功耗接收机),可以采用包络检波,即通过幅度检测出OOK符号,这种方式的复杂度较低,接收机功耗较低。
对于OOK调制,低功耗接收机可以有三种架构。第一种架构是基于零中频(Zero IF)的包络检波架构,其中包络检波可以在基带中完成。第二种架构是基于低中频(Low IF)的包络检波架构,其中包络检波可以在中频中完成。第三种架构是基于射频的包络检波架构,其中包络检波可以在射频中完成。以上三种架构都可以实现上述的两类接收方法。
在通信过程中,频率漂移(Frequency Drift)在一段时间内会累积成为时间偏差(Timing Error)。该定时偏差可以为一个或多个OOK符号。
对于第一类接收方法(低功耗接收机周期地检测唤醒信号),当检测周期过大时,累积的定时偏差将会很大。当定时偏差超过一定程度时,解调解码性能急剧下降,表现为较大的漏检率(Miss Detection Rate,MDR)和/或虚警率(False Alarm Rate,FAR)。
对于第二类接收方法(低功耗接收机一直处于检测唤醒信号的状态),当网络设备长时间没有发送唤醒信号时,累积的定时偏差将会很大。当定时偏差超过一定程度时,网络设备发送唤醒信号和低功耗接收机检测到唤醒信号之间的时间间隔过大,导致延迟过大。
在此基础上,低功耗接收机可以通过一个周期的同步信号进行同步,以减小定时偏差。同步信号可以采用OOK调制。同步信号也可以不采用OOK调制,以频域序列的形式发送(称为OFDM调制或波形)。由于频域序列在时域上表现为滤波后的时域序列接收机可以采用时域相关方式(即接收时域信号与本地序列或序列的部分的时域版本进行相关)。实际上,时域相关方式等价于频域点乘方式(即接收到的频域信号与本地的序列或序列的部分的频域版本进行点乘)。
但是,即使低功耗接收机通过一个周期的同步信号进行同步,仍然会有残留的定时偏差。该残留的定时偏差仍然可以为一个或多个OOK符号。
对于第一类接收方法(低功耗接收机周期地检测唤醒信号),低功耗接收机可以在时间窗口(Window)内尝试多次解调解码(如果唤醒信号是信道)或序列检测(如果唤醒信号是信号序列),以减轻残留的定时偏差的影响。
对于第二类接收方法(低功耗接收机一直处于检测唤醒信号的状态),低功耗接收机可以将任意时刻作为假设的唤醒信号起点,尝试解调解码(如果唤醒信号是信道)或序列检测(如果唤醒信号是信号序列),以减轻残留的定时偏差的影响。
以上两种接收方法下的检测都需要低功耗接收机在一段时间内尝试多次的解调解码或序列检测,这样都导致低功耗接收机的复杂度和功耗过大。因此,相关技术中,在残留的定时偏差下,如何快速消除定时偏差,降低低功耗接收机的复杂度和功耗,是亟待解决的问题。
在本申请实施例中,网络设备在第一比特序列的开头或结尾添加X个比特,其中X为正整数。这样,网络设备将X个比特添加至第一比特序列的开头或者结尾,终端设备的低功耗接收机根据X个比特可以快速确定出第一比特序列的开始位置,能够快速消除定时偏差,可以避免低功耗接收机在一段时间内尝试多次的解调解码或序列检测,能够降低低功耗接收机的复杂度和功耗。
以下通过具体实施例对本申请所示的方案进行详细说明。需要说明的是,以下几个实施例可以独立存在,也可以相互结合,对于相同或相似的内容,在不同的实施例中不再重复说明。
以下结合图2所示的实施例,对信号处理的过程进行说明。图2为本申请实施例提供的一种信号处理方法的流程示意图。请参见图2,该方法可以包括:
S201、在第一比特序列的开头或结尾添加X个比特,其中X为正整数。
本申请实施例中的执行主体为网络设备,具体可以为基站(发射机)等。第一比特序列是编码后输出的比特序列。具体来说,第一比特序列可以是数据部分等。本申请实施例中的编码可以是信道编码,例如曼彻斯特(Manchester)编码、分组(Block)编码、卷积(Convolutional)码、极化(Polar)码或低密度奇偶校验(Low Density Parity Check,LDPC)码。该第一比特序列具有一定的特征,例如经过曼彻斯特编码后的比特序列最多只有连续的T个1。而X个比特具有一定的模式,如连续N个1。这样,只需保证N>T,网络设备向终端设备发送该序列之后,低功耗接收机检测到该连续N个1,就能确定第一比特序列的开始位置。这样,可以避免低功耗接收机在一段时间内尝试多次对整个唤醒进行检测。确定第一比特序列的开始位置的过程也可以看作获得定时信息即纠正定时偏差的过程。确定第一比特序列的开始位置的过程还可以看作充电的过程。
具体的,网络设备可以添加X个比特在第一比特序列的开头。一般来说,OOK符号序列的输出在时域是正向的,因此添加X个比特在第一比特序列的开头,可以令X个比特在OOK符号序列的开头。网络设备也可以添加X个比特在第一比特序列的结尾。由于第一比特序列可能采用特殊方式映射到子载波上,导致OOK符号序列的输出在时域是反向的,因此添加X个比特在第一比特序列的结尾,可以令X个比特在OOK符号序列的开头。
本申请实施例提供的信号处理方法,网络设备在第一比特序列的开头或结尾添加X个比特,其中X为正整数。这样,网络设备将X个比特添加至第一比特序列的开头或者结尾,终端设备的低功耗接收机根据X个比特可以快速确定出第一比特序列的开始位置,能够快速消除定时偏差,可以避免低功耗接收机在一段时间内尝试多次的解调解码或序列检测,能够降低低功耗接收机的复杂度和功耗。
在一种可能的实施方式中,第一比特序列为编码后输出的比特序列。本申请实施例中,第一比特序列可以是网络设备编码后输出的比特序列。
在一种可能的实施方式中,X个比特为前导部分。一般来说,前导部分在唤醒信号的前面部分。前导部分也可以称为第一部分或唤醒信号的第一部分或唤醒信号的前导部分。一般来说,唤醒信号中的数据部分在前导部分之后。数据部分也可以称为第二部分或唤醒信号的第二部分或唤醒信号的数据部分。
本申请实施例中,X个比特可以是前导(Preamble)部分。这样,可以区别于数据(Data)部分,数据部分则是该由前导部分的后续OOK符号携带。
在一种可能的实施方式中,第一比特序列为数据部分。
本申请实施例中,该第一比特序列可以是数据部分。这样,数据部分可以紧接着前导部分。实际上,唤醒信号一般可以包括前导部分和数据部分。一般地,前导部分用于进一步的同步。前导部分可以看作承载1比特信息的信号(序列)。数据部分又可以称为消息(Message)部分或负荷(Payload)部分。一般地,数据部分用于指示网络设备需要唤醒的终端设备的标识,即UE ID,或其部分,或UE组(Group)的标识,或UE子组(Subgroup)的标识。数据部分可以看作承载一个或多个比特的信道。
在一种可能的实施方式中,X个比特为N个数值为1或0的比特,N为正整数。
本申请实施例中,第一比特序列可以是经过曼彻斯特编码后的比特序列,最多只有连续的T个1,当X个比特为N个1的比特,低功耗接收机检测到N个1,由于N>T,就能确定第一比特序列的开始位置。N个1的比特可以称为同步(Sync)部分。此时,相当于同步部分作为前导部分。当然,X个比特也可以为N个0的比特,代表非零功率。这样,可以避免低功耗接收机在一段时间内尝试多次对整个唤醒进行检测。确定第一比特序列的开始位置的过程也可以看作获得定时信息即纠正定时偏差的过程。确定第一比特序列的开始位置的过程还可以看作充电的过程。
在一种可能的实施方式中,X个比特为N个数值为1或0的比特加上M个比特,其中N为正整数,M为正整数。
本申请实施例中,第一比特序列可以是经过的曼彻斯特编码后的比特序列,最多只有连续的T个1,当X个比特包含N个1的比特,低功耗接收机检测到N个1,由于N>T,就能确定M个比特的开始位置,接着低功耗接收机检测到M个比特或者等待M个比特的传输时间,就能确定第一比特序列的开始位置。M个比特可以称为分隔(Delimiter)部分。此时,相当于同步部分加上分隔部分共同组成前导部分。同样的,X个比特也可以包含N个0的比特,代表非零功率。这样,可以避免低功耗接收机在一段时间内尝试多次对整个唤醒进行检测。确定第一比特序列的开始位置的过程也可以看作获得定时信息即纠正定时偏差的过程。确定第一比特序列的开始位置的过程还可以看作充电的过程。
在一种可能的实施方式中,N为等于或者大于3的整数。
在一种可能的实施方式中,N为等于或者大于5的整数。
在一种可能的实施方式中,N为等于或者大于7的整数。
本申请实施例中,当X个比特为N个数值为1或0的比特,或者X个比特位为N个数值为1或0的比特加上M个比特时,数值N的取值可以为等于或者大于3的整数,也可以为等于或者大于5的整数,还可以为等于或者大于7的整数。
具体的,当N取值为3时,第一比特序列可以是经过1/2码率的曼彻斯特编码后的比特序列,最多只有连续的两个1,当X个比特为N个1的比特为连续的3个1,低功耗接收机可以检测到3个1,就能确定第一比特序列的开始位置。N的取值也可以为大于3的整数,这是由于OOK符号经过衰落信道后,会有失真(Distortion),采用较大的N值可以避免失真导致的接收机误判。
当N取值为5时,第一比特序列可以是经过2/4码率的曼彻斯特编码后的比特序列,最多只有连续的四个1,当X个比特为N个1的比特为连续的5个1,低功耗接收机可以检测到5个1,就能确定第一比特序列的开始位置。同样的,N的取值也可以为大于5的整数,这是由于OOK符号经过衰落信道后,会有失真,采用较大的N值可以避免失真导致的接收机误判。
当N取值为7时,第一比特序列可以是经过3/8码率的曼彻斯特编码 后的比特序列,最多只有连续的六个1,当X个比特为N个1的比特为连续的7个1,低功耗接收机可以检测到7个1,就能确定第一比特序列的开始位置。同样的,N的取值也可以为大于7的整数,这是由于OOK符号经过衰落信道后,会有失真,采用较大的N值可以避免失真导致的接收机误判。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以有以下几种类型:
在一种可能的实施方式中,M个比特为小区标识、跟踪区域标识或者无线接入网络标识其中任意一个。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以为全0。这样,低功耗接收机确定出M个比特的开始位置后,等待M个比特的传输时间(在此时间内进行数据部分接收的硬件切换),就能确定数据部分(第一比特序列)的开始位置。在某些情形中,低功耗接收机检测N个比特的硬件跟接收数据部分的硬件是不同的硬件。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以为小区标识(Identity,ID)、跟踪区域(Tracking Area,TA)标识或无线接入网络(Radio Access Network,RAN)标识。在蜂窝网中,小区间干扰(Inter-Cell Interference)、跟踪区域间干扰或无线接入网络间干扰是需要考虑的。网络设备可以通过在X个比特中承载小区相关的标识(可以是小区标识、跟踪区域标识或无线接入网络标识)来令低功耗接收机区分低功耗唤醒信号是否是当前的小区、跟踪区域或无线接入网络发送的。
在一种可能的实施方式中,M个比特为小区标识、跟踪区域标识或者无线接入网络标识其中任意一个的一部分。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以为小区标识、跟踪区域标识或无线接入网络标识其中任意一个的一部分。具体的,小区相关的标识的数量较多,当M较小时,可以使用小区相关的标识的一部分。
在一种可能的实施方式中,M个比特为小区标识、跟踪区域标识或者 无线接入网络标识其中任意一个加上全0或全1序列。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以为小区标识、跟踪区域标识或者无线接入网络标识其中任意一个加上全0或全1序列。这样,既能达到承载小区相关的标识的目的,又能达到低功耗接收机在一段时间内进行数据部分接收的硬件切换的目的。全1序列可以代表零功率。
在一种可能的实施方式中,M个比特为小区标识、跟踪区域标识或者无线接入网络标识其中任意一个的一部分加上全0或全1序列。
本申请实施例中,当X个比特为N个数值为1或0的比特加上M个比特时,M个比特可以为小区标识、跟踪区域标识或者无线接入网络标识其中任意一个的一部分加上全0或全1序列。这样,既能达到承载小区相关的标识的目的,又能达到低功耗接收机在一段时间内进行数据部分接收的硬件切换的目的。全1序列可以代表零功率。
在一种可能的实施方式中,M个比特为小区标识、跟踪区域标识或无线接入网络标识其中任意一个的第一部分,加扰的比特序列为小区标识、跟踪区域标识或无线接入网络标识其中任意一个的第二部分。
一般来说,可以通过对信道进行加扰来达到小区间干扰、跟踪区域间干扰或无线接入网络间干扰随机化的目的,然而,唤醒信号的数据部分长度较短,而小区相关的标识的数量较多,仅通过加扰难以达到干扰随机化的目的。因此,本申请实施例中加扰的比特序列和M个比特可以结合起来,比如加扰的比特序列和M个比特可以组成一个完整的小区相关的标识。
X个比特的具体模式除了上述X个比特为N个数值为1或0的比特、以及X个比特为N个数值为1或0的比特加上M个比特之外,X个比特也可以直接为前文所描述的M个比特。当X比特可以直接为M个比特时,假设M值较大,因此第一比特序列中出现M个比特的概率较小,也就是说,低功耗接收机误检测出M个比特的概率较小,因此此时无需连续N个1或0的比特作为数据部分的开始位置的指示。
在一种可能的实施方式中,X个比特为M个比特,其中M为正整数。
本申请实施例中,在一些场景中(如无需避免低功耗接收机在一段时 间内尝试多次对整个唤醒进行检测),低功耗接收机检测到M个比特或者等待M个比特的传输时间,就能确定第一比特序列的开始位置。M个比特可以称为分隔部分。此时,相当于分隔部分作为前导部分。确定第一比特序列的开始位置的过程也可以看作获得定时信息即纠正定时偏差的过程。确定第一比特序列的开始位置的过程还可以看作充电的过程。
类似的,X个比特具体可以包括以下几种模式:
在一种可能的实施方式中,X个比特为小区标识、跟踪区域标识或无线接入网络标识其中任意一个。
本申请实施例中,在蜂窝网中,小区间干扰、跟踪区域间干扰或无线接入网络间干扰是需要考虑的。网络设备可以通过X个比特中承载小区相关的标识(可以是小区标识、跟踪区域标识或无线接入网络标识)来令低功耗接收机区分低功耗唤醒信号是否是当前的小区、跟踪区域或无线接入网络发送的。

在一种可能的实施方式中,X个比特为小区标识、跟踪区域标识或无 线接入网络标识其中任意一个的第一部分,加扰的比特序列为小区标识、跟踪区域标识或无线接入网络标识其中任意一个的第二部分。
一般来说,也可以通过对信道进行加扰来达到小区间干扰、跟踪区域间干扰或无线接入网络间干扰随机化的目的,然而,唤醒信号的数据部分长度较短,而小区相关的标识的数量较多,仅通过加扰难以达到干扰随机化的目的。因此,本申请实施例中加扰的比特序列和X个比特可以结合起来,比如加扰的比特序列和X个比特可以组成一个完整的小区相关的标识。
在一种可能的实施方式中,X为一个正交频分复用OFDM符号上承载的开关键控OOK符号的数量。
本申请实施例中,数值X可以为一个OFDM符号上承载的OOK符号的数量。这样,该X个比特(X个OOK符号)承载在一个OFDM符号上,而数据部分(D个OOK符号)承载在另一个或多个OFDM符号上,低功耗接收机可以在后续的OFDM符号上接收数据部分,并且跳过OFDM符号的循环前缀(Cyclic Prefix,CP)部分。

S301、根据X个比特,确定第一比特序列的开头,其中X为正整数。
本申请实施例的执行主体为终端设备。终端设备的低功耗接收机检测到X比特,由于X个比特具有一定的模式,低功耗接收机能够确定第一比特序列的开始位置。这样,低功耗接收机可以先检测出该X比特确定第一比特序列的开始位置,避免低功耗接收机在一段时间内尝试多次的解调解码或序列检测。确定数据部分的开始位置的过程也可以看作获得定时信息(纠正定时偏差)的过程,能够快速消除定时偏差。
