目前在第五代移动通信技术(5th-Generation，5G)新无线(New Radio，NR)系统中，终端会持续地盲检控制信道，以判断是否需要从休眠状态醒来去指定的时频资源接收接入网设备发送的数据信息。这是因为在非授权频谱和共享频谱场景中，基站发送数据信息是机会性的，且基站在发送数据信息后只能占据当前的信道一小段时间就需要释放该信道，以使其他频谱能使用该信道，保证公平性。然而，终端设备持续地盲检控制信道，将浪费大量的功耗。

需要说明的是，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还存在另外的相同要素，此外，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体 含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。

为了能够更好地理解本申请实施例，下面对本申请实施例涉及的专业术语进行介绍：
离散傅立叶变换扩展的正交频分复用(Discrete Fourier Transform Spreading Orthogonal Frequency Division Multiplexing，DFT-S-OFDM)：是一种单载波调制方案，与传统正交频分复用相比具有较小的峰均功率比，DFT-S-OFDM作为其长期演进项目(LTE)的上行调制方案。
循环前缀(Cyclic Prefix，CP)：是一个数据符号后面的一段数据复制到该符号的前面形成的循环结构，这样可以保证有时延的OFDM信号在快速傅里叶变换(Fast Fourier Transform，FFT)积分周期内总是具有整倍数周期。将OFDM符号尾部的信号复制到头部构成的。CP的长度主要有两种，分别为常规循环前缀(Normal Cyclic Prefix)和扩展循环前缀(Extended Cyclic Prefix)。常规循环前缀长度4.7μs，扩展循环前缀长度16.67μs。循环前缀可以与其他多径分量信息相关联，得到完整的信息。此外循环前缀可以实现时间的预估计和频率同步。
单字离散傅立叶变换扩展的正交频分复用(Unique Word DFT-S-OFDM，UW DFT-S-OFDM)：是一种不包括CP的DFT-S-OFDM，可以减小UW DFT-S-OFDM的发射机结构与DFT-S-OFDM的发射机结构类似，都具有DFT模块、子载波映射模块、逆快速傅立叶变换(Inverse Fast Fourier Transform，IFFT)模块。但有两个主要的不同：1)在UW-DFT-S-OFDM发射机中，DFT模块输入的头部分和尾部分被插入了预设的序列，DFT模块输入依次包括头部分、数据部分和尾部分。这与传统的DFT-S-OFDM发射机不同，在DFT-S-OFDM发射机中，DFT模块的输入只有数据部分。由于DFT模块输入依次包括头部分、数据部分和尾部分，因此一个符号在时域上也依次包括头部分、数据部分和尾部分。2)UW DFT-S-OFDM波形中没有CP，因此一个时隙或时间间隔中的符号数往往多于 DFT-S-OFDM波形，例如DFT-S-OFDM波形在一个时隙或时间间隔内有14个符号，而UW DFT-S-OFDM有15个符号。UW DFT-S-OFDM波形中往往有一个符号是专门用于参考信号(Reference Signal，RS)或导频(Pilot)，以便于接收机在频域上进行信道估计，估计出信道的频域相应。这里称为参考信号符号。对于参考信号符号，其数据部分也是预设的序列，与头部分和尾部分的预设的序列构成一个预设的长序列；对于参考信号符号外的其它符号，其头部分和尾部分的预设的序列也是预设的长序列的一部分。每个符号上的头部分和尾部分都可以不同，并且可以配置的。每个符号的头部分可以用于减少符号间干扰。参考信号符号外的其它符号的尾可以用于信道估计值的更新，可以估计出时变引起的信道响应的变化。
零尾离散傅立叶变换扩展的正交频分复用(Zero Tail DFT-S-OFDM，ZT DFT-S-OFDM)：是另一种不包括CP的DFT-S-OFDM，可以看作是如上述的UW DFT-S-OFDM的变种。在ZT DFT-S-OFDM发射机中，DFT模块的输入的头部分和尾部分是零序列。这相当于UW DFT-S-OFDM的特殊形式。
为了能够更好地理解本申请实施例，下面对本申请实施例可应用的网络架构进行说明。
请参见图1，图1为本申请实施例提供的一种符号应用方法的网络架构示意图。如图1所示，该网络架构可以包括接入网设备和终端设备，终端设备通过服务小区与接入网设备建立连接。其中，该服务小区中可以包括一个或多个信道，以作为接入网设备和终端设备之间的数据传输媒介，例如物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理上行共享信道(Physical Uplink Control Channel，PUSCH)等等。
本申请实施例中所涉及的接入网设备，是网络侧的一种用于发射或接收信号的实体，可以用于将收到的空中帧与网络协议(Internet Protocol，IP)分组进行相互转换，作为终端设备与接入网的其余部分之间的路由器，其中接入网的其余部分可以包括IP网络等。接入网设备还可以协调对空中接口的属性管理。例如，接入网设备可以是LTE中的eNB，还可以是新无线控制器(New Radio Controller，NR controller)，可以是5G系统中的gNB，可以是集中式网元(Centralized Unit)，可以是新无线基站，可以是射频拉远模块，可以是微基站，可以是中继(Relay)，可以是分布式网元(Distributed Unit)，可以是接收点(Transmission Reception Point，TRP)或传输点(Transmission Point，TP)或者任何其它无线接入设备，但本申请实施例不限于此。
本申请实施例中涉及的终端设备，是用户侧的一种用于接收或发射信号的实体。终端设备可以是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。终端设备也可以是连接到无线调制解调器的其他处理设备。终端设备可以与无线接入网(Radio Access Network，RAN)进行通信。终端设备也可以称为无线终端、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device)、或用户设备(User Equipment，UE)等等。终端设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，终端设备还可以是个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、等设备。常见的终端设备例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(Mobile  Internet Device，MID)、车辆、路边设备、飞行器、可穿戴设备，例如智能手表、智能手环、计步器等，但本申请实施例不限于此。以下对本申请所提供的通信方法及相关设备进行详细地介绍。
在目前的技术中，终端设备通过盲检控制信令来确认是否需要从休眠状态醒来去接收接入网设备发送的数据信息，而盲检控制信令和保持与网络侧的同步将使得终端设备浪费大量功耗。
为了能够降低数据传输的功耗，提高数据传输的效率，本申请实施例提供了一数据传输方法及通信装置，下面进一步对本申请实施例提供的数据传输方法及通信装置进行详细介绍。
请参见图2，图2为本申请实施例提供了一种数据传输方法的流程示意图。如图2所示的流程示意图可以包括以下步骤：
210、若检测到第一类符号的头部分为预设序列或信令，则由休眠状态切换至工作状态。
终端设备在检测到第一类符号的头部为预设序列或信令后，可以确定接入网设备有数据业务需要发送给终端设备，于是终端设备可以从休眠状态切换至工作状态，以接收接入网设备在指定的时频资源上发送的信息。其中，该第一类符号可以是终端设备或接入网设备指定的某一种类型的符号。该预设序列或信令可以是终端设备或接入网设备设置的，可以作为一种接入网设备有数据待发送的标识，若终端设备检测到该第一类符号的头部为该标识，则可以确定接入网设备有数据待发送。当采用预设信令的方式时，该预设信令要足够简单，以令终端设备使用较小的盲检复杂度就能确定或获取该预设信令。
在一种可能的实现方式中，终端设备还可以通过检测一个初始信号(Initial Signal)来判断是否需要由休眠状态切换至工作状态。
在一种可能的实现方式中，上述第一类符号所对应的波形可以是UW DFT-S-OFDM或者ZT DFT-S-OFDM。
在一种可能的实现方式中，上述第一类符号可以包含参考信号(Reference Signal，RS)、导频(Pilot)或前导(Preamble)。
在一种可能的实现方式中，上述第一类符号的头部分可以包含参考信号、导频或前导。在一种可能的实现方式中，上述第一类符号的位置可以由信令给出。其中，信令可以包含于：无线资源控制(Radio Resource Control，RRC)信令；媒质接入控制(Medium Control Access，MAC)信令、MAC包数据单元(MAC Packet Data Unit，MAC PDU)或MAC控制元素(MAC Control Element，MAC CE)；物理下行控制信道(Physical Downlink Control Channel，PDCCH)、下行控制信息(Downlink Control Information，DCI)或时隙格式指示(Slot Format Indicator，SFI)。
在一种可能的实现方式中，上述第一类符号的头部分的长度大于第一类符号外的符号的头部分。可以理解的是，预设序列的长度会相较于其他符号的头部分长度更长。具有区别性，终端设备可以将符号的头部分长度作为判断是否为预设序列的条件之一。
在一种可能的实现方式中，上述第一类符号的头部分为离散傅里叶变换DFT模块输入的低索引部分。其中，如图3所示，当DFT模块的输入是正序时，即DFT模块的输入的索引是由小到大排列的，如1、2、3等，这样，DFT模块输入的低索引部分就可以是第一类符号的头部分。
在一种可能的实现方式中，上述第一类符号的头部分为离散傅里叶变换DFT模块输入的索引值小于第一预设索引值的索引指示的部分。如图3所示，当DFT模块的输入为正序时，小于该第一预设索引值的索引指示的部分则为第一类符号的头部分，大于该第一预设索引值的索引指示的部分则为数据部分和尾部分。其中，第一预设索引值可以是终端设备 或接入网设备配置的。
在一种可能的实现方式中，上述第一类符号的头部分在所述第一类符号的数据部分的前面。如图3所示，当DFT模块正序输入时，第一类符号的结构从左到右分别为头部分、数据部分和尾部分，则位于数据部分前面的部分则为第一类符号的头部分。
在一种可能的实现方式中，上述第一类符号的头部分为离散傅里叶变换DFT模块输入的高索引部分。其中，如图4所示，当DFT模块的输入是逆序时，即DFT模块的输入的索引是由大到小排列的，如100、99、98等，这样，DFT模块输入的高索引部分就可以是第一类符号的头部分。
在一种可能的实现方式中，上述第一类符号的头部分为离散傅里叶变换DFT模块输入的索引值大于第二预设索引值的索引指示的部分。如图4所示，当DFT模块的输入为逆序时，大于该第二预设索引值的索引指示的部分则为第一类符号的头部分，小于该第二预设索引值的索引指示的部分则为数据部分和尾部分。其中，第二预设索引值可以是终端设备或接入网设备配置的。
在一种可能的实现方式中，第一类符号的头部分在所述第一类符号的数据部分的后面。如图4所示，当DFT模块逆序输入时，第一类符号的结构从左到右分别为尾部分、数据部分和头部分，则位于数据部分后面的部分则为第一类符号的头部分。
220、接收接入网设备发送的数据。
终端设备由休眠状态切换至工作状态之后，可以检测控制信道，检测控制信道则意味着终端设备成功由休眠状态切换至了工作状态。其中，该控制信道可以包括PDCCH、至少一个DCI格式(Format)的PDCCH或者至少一个搜索空间集(Search Space Set)的PDCCH。例如，终端设备可以在PDCCH上检测下行调度信息，以在该下行调度信息所指示的时频资源上接收相应的数据。
在一种可能的实现方式中，终端设备由休眠状态切换至工作状态之后，可以启动定时器，启动了定时器后则意味着终端设备成功由休眠状态切换至了工作状态。其中，该定时器可以是工作状态持续时间内的定时器，也可以是非激活定时器(Inactivity Timer)。该工作状态持续时间内的定时器可以是终端设备进入工作状态就开启的定时器，该定时器的运行时间段则为终端设备处于工作状态的时间段。非激活定时器可以是终端设备在监听控制信道期间收到混合重传请求(HARQ)初始重传的控制信令时打开或重启的，在该非激活定时器超时之前，终端设备可以连续监听控制信道。说明若第一类符号的头部为预设序列或信令，则该预设序列可以指示终端设备开启非激活定时器。
通过本申请实施例，终端设备可以在检测到第一类符号的头部为预设序列或信令时，确定接入网设备有待发送的数据需要终端设备接收，则可以由休眠状态切换至工作状态。终端设备可以根据在工作状态中获取到的调度信息去响应的时频资源上接收接入网设备发送的数据。这样，终端设备不用持续地盲检控制信道来判断是否需要由休眠状态切换至工作状态，而是根据第一类符号的头部是否预设序列或信令来判断，可以大大节省终端设备的功耗。
请参见图5，图5为本申请实施例提供了另一种数据传输方法的流程示意图。如图5所示的流程示意图可以包括以下步骤：
510、若检测到第二类符号的头部分为预设序列或信令，则由休眠状态切换至工作状态。
在一种可能的实现方式中，对于某些场景，接入网设备可以设置第二类符号的头部分为零序列、零功率序列或低功率序列后，第二类符号在时域上就可以留出一个低发射功率的时间段，在该低发射功率的时间段内，接入网设备可以发射一些不同系统或不同波形的信号。其中，该第二类符号可以是终端设备或接入网设备指定的某一种类型的符号。接入 网设备可以将一些不同系统或不同波形的信号添加至第二类符号中已被终端设备设置为零序列、零功率序列或低功率序列的头部分中，这样可以保证不同系统的共存性。其中，该共存性指的是，第二类符号的头部分若为预设序列或信令(不同的系统都能识别的)，则代表该第二类符号的头部可以被不同的系统互相识别，在不同的系统之间共存。
需要说明的是，终端设备还可以假设第二类符号的头部分为零序列、零功率序列或低功率序列。也就是说，即便第二类符号的头部分不为零序列、零功率序列或低功率序列，终端设备也可以假设为零序列、零功率序列或低功率序列，这样也可以使接入网设备在发送第二类符号的头部分的时候，加入其他的信号。
在一种可能的实现方式中，上述第二类符号的头部分之外的部分所对应的波形可以是UW DFT-S-OFDM或者ZT DFT-S-OFDM。
在一种可能的实现方式中，上述第二类符号的头部分所对应的波形可以是UW DFT-S-OFDM或者ZT DFT-S-OFDM之外的波形。
在一种可能的实现方式中，上述第二类符号所对应的波形可以是UW DFT-S-OFDM或者ZT DFT-S-OFDM之外的波形。此时，接入网设备可以在整个第二类符号位置上加入其他的信号，例如加入公共前导(Common Preamble)。
在一种可能的实现方式中，上述第二类符号可以包含参考信号(Reference Signal，RS)、导频(Pilot)或前导(Preamble)。
在一种可能的实现方式中，上述第二类符号的头部分可以包含参考信号、导频或前导。在一种可能的实现方式中，上述第二类符号的位置可以由信令给出。其中，信令可以包含于：无线资源控制(Radio Resource Control，RRC)信令；媒质接入控制(Medium Control Access，MAC)信令、MAC包数据单元(MAC Packet Data Unit，MAC PDU)或MAC控制元素(MAC Control Element，MAC CE)；物理下行控制信道(Physical Downlink Control Channel，PDCCH)、下行控制信息(Downlink Control Information，DCI)或时隙格式指示(Slot Format Indicator，SFI)。
