Description

通信方法、设备及系统 技术领域
本申请涉及通信领域，尤其涉及通信方法、设备及系统。
背景技术
物联网(internet of thing，IoT)是“物物相连的互联网”。它将互联网的用户端扩展到了任何物品与物品之间，使得在任何物品与物品之间可以进行信息交换和通信。这样的通信方式也称为机器间通信(machine type communications，MTC)。
在窄带物联网(narrow band internet of thing，NB-IoT)系统的版本(release，Rel)16中，为了使NB-IoT系统和(new radio，NR)系统更好地共享频谱资源，讨论了NB-IoT系统和NR系统共存的问题，并最终确定NB-IoT系统可以预留资源，该预留的资源可以用于NR系统进行调度。
然而，如何预留资源，目前并没有相关的解决方案。
发明内容
本申请实施例提供一种通信方法、设备及系统，在预留资源时，可以避免终端设备的参考信号与其他终端设备的数据发生冲突，进而可以避免对终端设备的信道估计性能的影响。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供了一种通信方法及相应的通信装置。该方案中，终端设备接收来自网络设备的资源配置信息，并根据该资源配置信息，确定第一时间单元内第一资源对应的符号。其中，第一资源对应的符号不包括第一时间单元内参考信号所在的符号，该第一资源不用于该终端设备对应的数据传输。基于该方案，在预留资源时忙不将参考信号所在的符号作为第一资源对应的符号，因此网络设备不会在参考信号所在的符号进行其他终端设备的数据调度，从而可以避免该终端设备的参考信号与其他终端设备的数据传输发生冲突，进而可以避免对终端设备的信道估计性能的影响。
在一种可能的设计中，该资源配置信息包括第一时间单元内，除参考信号所在的符号之外的n个符号对应的指示信息，其中，第一符号对应的指示信息用于指示第一符号是否为第一资源对应的符号，第一符号为n个符号中的一个符号，n为正整数。
在该方案中，由于资源配置信息不会指示参考信号所在的符号是否为第一资源对应的符号，从而，终端设备不可能根据资源配置信息确定参考信号所在的符号为第一资源对应的符号，因此可以实现第一资源对应的符号中不包括参考信号所在的符号。
在一种可能的设计中，该资源配置信息包括第一时间单元包括m个符号，该资源配置信息包括该m个符号对应的指示信息，其中，第二符号对应的指示信息用于指示该第二符号是否为该第一资源对应的符号，该第二符号为该m个符号中的一个符号，m为正整数；终端设备根据该资源配置信息，确定第一时间单元内第一资源对应的符号，包括：若该第二符号为该参考信号所在的符号，且该第二符号对应的指示信息指示该第二符号为该第一资源对应的符号，该终端设备确定该第一资源对应的符号不包括该第二符号；若该第二符号不为该参考信号所在的符号，且该第二符号对应的指示信息指示该第二符号为该第一资源对应的符号，该终端设备确定该第一资源对应的符号包括该第二符号。
在该方案中，即使资源配置信息指示参考信号所在的符号为第一资源对应的符号，终端设备也不将参考信号所在的符号确定为第一资源对应的符号，也可以理解为终端设备忽略该指示，从而可以实现终端设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号。
在一种可能的设计中，第一时间单元包括m个符号，该资源配置信息包括该m个符号对应的指示信息，其中，第三符号对应的指示信息用于指示该第三符号是否为该第一资源对应的符号，该第三符号为该m个符号中的一个符号，m为正整数；终端设备根据该资源配置信息，确定第一时间单元内第一资源对应的符号，包括：若该第三符号为该参考信号所在的符号，且该第三符号对应的指示信息指示该第三符号为该第一资源对应的符号，该终端设备将该参考信号所在的符号由该第三符号调整至第四符号，并确定该第一资源对应的符号包括该第三符号；若该第三符号不为该参考信号所在的符号，且该第三符号对应的指示信息指示该第三符号为该第一资源对应的符号，该终端设备确定该第一资源对应的符号包括该第三符号。
在该方案中，若资源配置信息指示参考信号所在的符号为第一资源对应的符号，终端设备可以将参考信号所在的符号调整至资源配置信息指示的不为第一资源对应的符号的一个符号，从而可以实现终端设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号。
在一种可能的设计中，述m个符号中包括第五符号，该第五符号为该参考信号所在的符号，且该第五符号对应的指示信息指示该第五符号不为该第一资源对应的符号；该通信方法还包括：终端设备将该参考信号所在的符号由该第五符号调整至第六符号，该第五符号与该第六符号之间的间隔等于该第三符号与该第四符号之间的间隔。
在该方案中，由于终端设备可以相应地将参考信号所在的符号由第五符号调整至第六符号，因此可以保证参考信号所在的至少两个符号之间的位置相当于调整之前保持不变，从而避免参考信号的位置发生跳变，进而保证信道估计可以采用一套滤波参数，降低信道估计的实现复杂度。
在一种可能的设计中，该通信方法还包括：终端设备接收来自该网络设备的第一指示信息，该第一指示信息包括偏置值，该偏置值表示该第三符号和该第四符号之间的间隔；或者，该第一指示信息包括该第四符号的位置信息。
在一种可能的设计中，该通信方法还包括：终端设备丢弃该第一资源对应的符号所承载的数据。
在一种可能的设计中，参考信号包括以下一项或多项：窄带参考信号NRS、窄带定位参考信号NPRS、解调参考信号DMRS、或者小区参考信号CRS。
第二方面，提供了一种通信方法及相应的通信装置。该方案中，网络设备确定资源配置信息，并向终端设备发送该资源配置信息。其中，该资源配置信息用于终端设备确定第一时间单元内第一资源对应的符号，第一资源对应的符号不包括第一时间单元内参考信号所在的符号，第一资源不用于终端设备对应的数据传输。其中，第二方面所带来的技术效果可参见上述第一方面所带来的技术效果，此处不再赘述。
在一种可能的设计中，资源配置信息包括该第一时间单元内，除该参考信号所在的符号之外的n个符号对应的指示信息，其中，第一符号对应的指示信息用于指示该第一符 号是否为该第一资源对应的符号，该第一符号为该n个符号中的一个符号，n为正整数。
在一种可能的设计中，第一时间单元包括m个符号，该资源配置信息包括该m个符号对应的指示信息，其中，第二符号对应的指示信息用于指示该第二符号是否为该第一资源对应的符号，该第二符号为该m个符号中的一个符号，m为正整数；该通信方法还包括：若该第二符号为该参考信号所在的符号，且该第二符号对应的指示信息指示该第二符号为该第一资源对应的符号，该网络设备确定该第一资源对应的符号不包括该第二符号；若该第二符号不为该参考信号所在的符号，且该第二符号对应的指示信息指示该第二符号为该第一资源对应的符号，该网络设备确定该第一资源对应的符号包括该第二符号。
基于该方案，可以实现网络设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号，同时使得网络设备和终端设备确定的第一资源对应的符号保持一致。
在一种可能的设计中，第一时间单元包括m个符号，该资源配置信息包括该m个符号对应的指示信息，其中，第三符号对应的指示信息用于指示该第三符号是否为该第一资源对应的符号，该第三符号为该m个符号中的一个符号，m为正整数；该通信方法还包括：若该第三符号为该参考信号所在的符号，且该第三符号对应的指示信息指示该第三符号为该第一资源对应的符号，该网络设备将该参考信号所在的符号由该第三符号调整至第四符号，并确定该第一资源对应的符号包括该第三符号；若该第三符号不为该参考信号所在的符号，且该第三符号对应的指示信息指示该第三符号为该第一资源对应的符号，该网络设备确定该第一资源对应的符号包括该第三符号。
基于该方案，可以实现网络设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号，同时使得网络设备和终端设备确定的第一资源对应的符号保持一致。
在一种可能的设计中，该m个符号中包括第五符号，该第五符号为该参考信号所在的符号，且该第五符号对应的指示信息指示该第五符号不为该第一资源对应的符号；该通信方法还包括：该网络设备将该参考信号所在的符号由该第五符号调整至第六符号，该第五符号与该第六符号之间的间隔等于该第三符号与该第四符号之间的间隔。
在一种可能的设计中，该通信方法还包括：该网络设备向该终端设备发送第一指示信息，该第一指示信息包括偏置值，该偏置值表示该第三符号和该第四符号之间的间隔；或者，该第一指示信息包括该第四符号的位置信息。
在一种可能的设计中，该通信方法还包括：网络设备丢弃该第一资源对应的符号所承载的数据。
在一种可能的设计中，参考信号包括以下一项或多项：窄带参考信号NRS、窄带定位参考信号NPRS、解调参考信号DMRS、或者小区参考信号CRS。

具体实施方式
为了方便理解本申请实施例的技术方案，首先给出本申请相关技术或名词的简要介绍如下。
第一，IoT：
IoT是“物物相连的互联网”。它将互联网的用户端扩展到了任何物品与物品之间，使得在任何物品与物品之间可以进行信息交换和通信。这样的通信方式也称为机器间通信(machine type communications，MTC)。其中，通信的节点称为IOT终端或IOT设备。典型的IoT应用包括车联网、智能社区、工业检测监控、智能抄表、智能电网、智能农业、智能交通、智能家居以及环境检测等各个方面。
由于物联网需要应用在多种场景中，比如从室外到室内，从地上到地下，因而对物联网的设计提出了很多特殊的要求。比如，由于某些场景下的IOT终端应用在覆盖较差的环境下，如电表水表等通常安装在室内甚至地下室等无线网络信号很差的地方，因此需要覆盖增强的技术来解决。或者，由于某些场景下的IOT终端的数量要远远大于人与人通信的设备数量，也就是说需要大规模部署，因此要求能够以非常低的成本获得并使用IOT终端。或者，由于某些场景下的IOT终端传输的数据包很小，并且对延时并不敏感，因此要求支持低速率的IOT终端。或者，由于在大多数情况下，IOT终端是通过电池来供电的，但是同时在很多场景下，IOT终端又要求能够使用十年以上而不需要更换电池，这就要求IOT终端能够以极低的电力消耗来工作。
为了满足上述需求，移动通信标准化组织第三代合作伙伴计划(3rd generation partnership project，3GPP)在RAN#62次全会上通过了一个新的研究课题来研究在蜂窝网络中支持极低复杂度和低成本的物联网的方法，并且在RAN#69次会议上立项为NB-IoT课题。
第二、NR：
面对MTC通信、智慧城市、智能交通、无人驾驶，虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)等新兴应用出现，NR系统(也称为第五代(5thgeneration，5G)系统)将支持增强移动宽带(enhanced mobile broadband，eMBB)、极高可靠极低时延通信(ultra reliable and low latency communications，URLLC)和海量机器类通信(massive machine type communications，mMTC)三大应用。目前3GPP R15和R16 NR主要针对的是eMBB和URLLC应用。其中eMBB处理的是以人为中心的使用场景，涉及用户对多媒体内容、服务和数据的访问。eMBB将满足数据流量爆发式增长和用户数量增强的需求，致力于提供更好的用户体验，相比长期演进(long term evolution，LTE)系统(也称为第四代(4thgeneration，4G)系统)能够支持更高速率，更低时延。
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行描述。其中，在本申请的描述中，除非另有说明，“/”表示前后关联的对象是一种“或”的关系，例如，A/B可以表示A或B；本申请中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况，其中A,B可以是单数或者复数。并且，在本申请的描述中，除非另有说明，“多个”是指两个或多于两个。“以下至少一项(个)”或其类似表达，是指的这些项中的任意组合，包括单项(个)或复数项(个)的任意组合。例如，a，b，或c中的至少一项(个)，可以表示：a，b，c，a-b，a-c，b-c，或a-b-c，其中a，b，c可以是单个，也可以是多个。另外，为了便于清楚描述本申请实施例的技术方案，在本申请的实施例中，采用了“第一”、“第二”等字样对功能和作用基本相同的相同项或相似项进行区分。本领域技术人员可以理解“第一”、“第二”等字样并不对数量和执行次序进行限定，并且“第一”、“第二”等字样也并不限定一定不同。同时，在本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念，便于理解。
本申请实施例可以适用于LTE系统，如NB-IoT系统中；也可以适用于其他无线通信系统，例如全球移动通信系统(global system for mobile communication，GSM)，移动通信系统(universal mobile telecommunications system，UMTS)，码分多址接入(code division multiple access，CDMA)系统，宽带码分多址(wideband code division multiple access，WCDMA)，5G网络以及面向未来的新的网络系统等，本申请实施例对此不作具体限定。其中，上述适用本申请的通信系统仅是举例说明，适用本申请的通信系统不限于此，在此统一说明，以下不再赘述。此外，术语“系统”可以和“网络”相互替换。
如图1所示，为本申请实施例提供的一种通信系统10。该通信系统10包括一个网络设备20，以及与该网络设备20连接的一个或多个终端设备30。可选的，不同的终端设备30之间可以相互通信。
以图1所示的网络设备20与任一终端设备30进行交互为例，本申请实施例中，网络设备20确定资源配置信息，并向终端设备30发送该资源配置信息；终端设备30接收来自网络设备20的资源配置信息，并根据该资源配置信息确定第一时间单元内第一资源对应的符号，该第一资源对应的符号不包括第一时间单元内参考信号所在的符号，该第一资源不用于该终端设备30对应的数据传输。基于该方案，在预留资源时，不将参考信号所在的符号作为第一资源对应的符号，因此网络设备不会在参考信号所在的符号进行其他终端设备的数据调度，从而可以避免终端设备30对应的参考信号与其他终端设备的数据传输发生冲突，进而可以避免因冲突影响终端设备30的信道估计性能以及其他终端设备的数据传输性能。
可选的，本申请实施例中的网络设备20，是一种将终端设备30接入到无线网络的设备，可以是LTE中的演进型基站(evolutional Node B，eNB或eNodeB)；或者GSM或CDMA中的基站(base Transceiver Station，BTS)；或者WCDMA系统中的 基站(NodeB)；或者5G网络或者未来演进的公共陆地移动网络(public land mobile network，PLMN)中的基站，宽带网络业务网关(broadband network gateway，BNG)，汇聚交换机或非第三代合作伙伴项目(3rd generation partnership project，3GPP)接入设备等，本申请实施例对此不作具体限定。可选的，本申请实施例中的基站可以包括各种形式的基站，例如：宏基站，微基站(也称为小站)，中继站，接入点等，本申请实施例对此不作具体限定。
可选的，本申请实施例中的终端设备30，可以是用于实现无线通信功能的设备，例如终端或者可用于终端中的芯片等。其中，终端可以是LTE网络或者未来演进的PLMN中的用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、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、个人数字处理(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、车载设备或可穿戴设备，VR终端设备、AR终端设备、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)中的无线终端等。终端可以是移动的，也可以是固定的。
可选的，本申请实施例中的网络设备20与终端设备30也可以称之为通信装置，其可以是一个通用设备或者是一个专用设备，本申请实施例对此不作具体限定。
可选的，如图2所示，为本申请实施例提供的网络设备20和终端设备30的结构示意图。
其中，终端设备30包括至少一个处理器(图2中示例性的以包括一个处理器301为例进行说明)和至少一个收发器(图2中示例性的以包括一个收发器303为例进行说明)。可选的，终端设备30还可以包括至少一个存储器(图2中示例性的以包括一个存储器302为例进行说明)、至少一个输出设备(图2中示例性的以包括一个输出设备304为例进行说明)和至少一个输入设备(图2中示例性的以包括一个输入设备305为例进行说明)。

需要说明的是，本申请实施例中的时隙、子帧、半帧、无线帧(或者称为帧)和超帧可以参考第一通信系统中的相关定义，也可以参考第二通信系统中的相关定义。
其中，在本申请实施例的不同实现方式下，网络设备确定的资源配置信息也可能不同，具体的：
在一种可能的实现方式中，网络设备确定的该资源配置信息包括第一时间单元内，除参考信号所在的符号之外的n个符号对应的指示信息，其中，第一符号对应的指示信息用于指示第一符号是否为第一资源对应的符号，第一符号为n个符号中的一个符号；n小于m，m为第一时间单元包括的符号总数，n和m均为正整数。
其中，第一符号为n个符号中的一个符号可以理解为：第一符号为n个符号中的任意一个符号，比如，该n个符号如果按照时间先后顺序进行编号为符号0，符号1，…，符号n-1，则第一符号可以为符号s，其中s的取值集合为0，1，…，n-1。
可选的，该n个符号对应的指示信息可以是位图的形式，位图中的一个比特可以表示一个符号对应的指示信息，或者可以表示n个符号中多个离散符号对应的指示信息，或者可以表示n个符号中多个连续符号对应的指示信息，本申请实施例对此不做具体限定。
示例性的，第一时间单元可以为一个子帧，以第一时间单元包括子帧1，子帧1包括14个符号，参考信号所在的符号为子帧1内的第4个和第11个符号，即n为12为例，如图5a所示，资源配置信息可以采用12比特位图表示该12个符号对应的指示信息，其中，一个比特表示一个符号对应的指示信息，例如，当该比特为“1”时，指示该比特对应的符号为第一资源对应的符号，该比特为“0”时，指示该比特对应的符号不为第一资源对应的符号；或者，如图5b所示，资源配置信息可以采用6比特位图表示该12个符号对应的指示信息，其中，一个比特表示2个连续符号(除参考信号所在的符号之外)对应的指示信息，例如，当该比特为“1”时，指示该比特对应的两个符号均为第一资源对应的符号，该比特为“0”时，指示该比特对应的两个符号均不为第一资源对应的符号。在另一种可能的实现方式中，第一时间单元包括m个符号，网络设备确定的该资源配置信息包括该m个符号对应的指示信息，其中，第二符号对应的指示信息用于指示第二符号是否为第一资源对应的符号，第二符号为该m个符号中的一个符号；或者，第三符号对应的指示信息用于指示第三符号是否为第一资源对应的符号，第三符号为该m个符号中的一个符号，m为正整数。
其中，第二符号或第三符号为m个符号中的一个符号可以理解为：第二符号或第三符号为m个符号中的任意一个符号，比如，该m个符号如果按照时间先后顺序进行编号为符号0，符号1，…，符号m-1，则第二符号可以为符号t1，第三符号可以为符号t2，其中t1和t2的取值集合均为0，1，…，m-1。
可选的，该m个符号对应的指示信息可以是位图的形式，位图中的一个比特可以 表示一个符号对应的指示信息，或者可以表示m个符号中多个离散符号对应的指示信息，或者可以表示m个符号中多个连续符号对应的指示信息，本申请实施例对此不做具体限定。
示例性的，第一时间单元可以为一个子帧，以第一时间单元包括子帧1，子帧1包括14个符号，即m为14，参考信号所在的符号为子帧1内的第4个和第11个符号为例，如图6a所示，资源配置信息可以采用14比特位图表示该14个符号对应的指示信息，其中，一个比特表示一个符号对应的指示信息，例如，当该比特为“1”时，指示该比特对应的符号为第一资源对应的符号，该比特为“0”时，指示该比特对应的符号不为第一资源对应的符号；或者，如图6b所示，资源配置信息可以采用7比特位图表示该14个符号对应的指示信息，其中，一个比特表示2个连续符号对应的指示信息，例如，当该比特为“1”时，指示该比特对应的两个符号均为第一资源对应的符号，该比特为“0”时，指示该比特对应的两个符号均不为第一资源对应的符号。
S402、网络设备向终端设备发送资源配置信息。相应的，终端设备接收来自网络设备的资源配置信息。
可选的，网络设备可以通过下行控制信息(downlink control information，DCI)、MAC控制元素(control element，CE)、MAC协议数据单元(protocol data unit，PDU)、或无线资源控制(radio resource control，RRC)信令中的一个或多个承载资源配置信息。
S403、终端设备根据资源配置信息，确定第一资源对应的符号。
其中，第一资源对应的符号不包括第一时间单元内参考信号所在的符号。
可选的，参考信号包括以下一项或多项：窄带参考信号(narrowband reference signal，NRS)、窄带定位参考信号(narrowband positioning reference signal，NPRS)、解调参考信号(demodulation reference signal，DMRS)、或者小区参考信号(cell-specific reference signal，CRS)。
其中，NRS和NPRS是NB-IoT系统中的参考信号，CRS和PRS是LTE系统以及eMTC或者LTE-M系统中的参考信号，DMRS可以是NB-IoT中的参考信号，也可以是LTE系统中的参考信号，也可以是eMTC或者LTE-M系统中的参考信号，还可以是NR系统中针对不同物理信道的解调参考信号。
其中，在本申请实施例的不同实现方式下，根据资源配置信息的不同，终端设备根据资源配置信息确定第一资源对应的符号的方法也可能不同，具体的：
在一种可能的实现方式中，资源配置信息包括第一时间单元内，除参考信号所在的符号之外的n个符号对应的指示信息时，终端设备根据资源配置信息确定第一资源对应的符号，可以包括：若第一符号对应的指示信息指示第一符号为第一资源对应的符号，终端设备确定第一资源对应的符号包括第一符号；若第一符号对应的指示信息指示第一符号不为第一资源对应的符号，终端设备确定第一资源对应的符号不包括第一符号，其中，第一符号为该n个符号中的一个符号。
示例性的，如图5a所示，终端设备可以根据资源配置信息确定第一资源对应的符号包括：子帧1的第1个和第6个符号；如图5b所示，终端设备可以根据资源配置信息确定第一资源对应的符号包括：子帧1的第1个、第2个、第13个和第14个符号。
在该方案中，由于资源配置信息不会指示参考信号所在的符号是否为第一资源对应的符号，从而，终端设备不可能根据资源配置信息确定参考信号所在的符号为第一资源对应的符号，因此可以实现第一资源对应的符号中不包括参考信号所在的符号。
需要说明的是，在该实现方式中，网络设备也可以根据与终端设备相同的方式确定第一资源对应的符号。
在另一种可能的实现方式中，第一时间单元包括m个符号，网络设备确定的该资源配置信息包括该m个符号对应的指示信息时，终端设备根据资源配置信息确定第一资源对应的符号，可以包括：若第二符号为参考信号所在的符号，且第二符号对应的指示信息指示第二符号为第一资源对应的符号，终端设备确定第一资源对应的符号不包括第二符号；若第二符号不为参考信号所在的符号，且第二符号对应的指示信息指示第二符号为第一资源对应的符号，终端设备确定第一资源对应的符号包括第二符号，其中，第二符号为该m个符号中的一个符号。
示例性的，如图6a所示，子帧1的第一个符号对应的指示信息指示第1个符号为参考信号所在的符号，且第1个符号不是参考信号所在的符号，因此终端设备确定第一资源对应的符号包括子帧1的第1个符号；子帧1的第4个符号对应的指示信息指示第4个符号为参考信号所在的符号，且第4个符号是参考信号所在的符号，因此终端设备确定第一资源对应的符号不包括子帧1的第4个符号，以此类推，终端设备根据资源配置信息最终可以确定第一资源对应的符号包括子帧1的第1个和第6个符号。
在该方案中，即使资源配置信息指示参考信号所在的符号为第一资源对应的符号，终端设备也不将参考信号所在的符号确定为第一资源对应的符号，也可以理解为终端设备忽略该指示，从而可以实现终端设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号。
需要说明的是，在该实现方式中，网络设备也可以根据与网络设备相同的方式确定第一资源对应的符号，即若第二符号为参考信号所在的符号，且第二符号对应的指示信息指示第二符号为第一资源对应的符号，网络设备确定第一资源对应的符号不包括第二符号；若第二符号不为参考信号所在的符号，且第二符号对应的指示信息指示第二符号为第一资源对应的符号，网络设备确定第一资源对应的符号包括第二符号。基于该方案，可以实现网络设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号，同时使得网络设备和终端设备确定的第一资源对应的符号保持一致。
在又一种可能的实现方式中，第一时间单元包括m个符号，网络设备确定的该资源配置信息包括该m个符号对应的指示信息时，终端设备根据资源配置信息确定第一资源对应的符号，可以包括：若第三符号为参考信号所在的符号，且第三符号对应的指示信息指示第三符号为第一资源对应的符号，终端设备将参考信号所在的符号由第三符号调整至第四符号，并确定第一资源对应的符号包括第三符号；若第三符号不为参考信号所在的符号，且第三符号对应的指示信息指示第三符号为第一资源对应的符号，终端设备确定第一资源对应的符号包括第三符号，其中，第三符号为该m个符号中的一个符号。
可选的，上述第四符号可以是资源配置信息指示的不为第一资源对应的符号的一 个符号。
示例性的，如图7a所示，子帧1的第1个符号不为参考信号所在的符号，且对应的指示信息指示第1个符号为第一资源对应的符号，因此终端设备确定第一资源对应的符号包括子帧1的第1个符号；子帧1的第4个符号是参考信号所在的符号，且第4个符号对应的指示信息指示第4个符号为参考信号所在的符号，因此终端设备将参考信号所在的符号由第4个符号调整为第3个符号(即第四符号)，并确定第一资源对应的符号包括子帧1的第4个符号，以此类推，终端设备根据资源配置信息最终可以确定第一资源对应的符号包括子帧1的第1个、第4个和第6个符号。
在该方案中，若资源配置信息指示参考信号所在的符号为第一资源对应的符号，终端设备可以将参考信号所在的符号调整至资源配置信息指示的不为第一资源对应的符号的一个符号，从而可以实现终端设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号。
需要说明的是，在该实现方式中，网络设备也可以根据与网络设备相同的方式确定第一资源对应的符号，即若第三符号为参考信号所在的符号，且第三符号对应的指示信息指示第三符号为第一资源对应的符号，网络设备将参考信号所在的符号由第三符号调整至第四符号，并确定第一资源对应的符号包括第三符号；若第三符号不为参考信号所在的符号，且第三符号对应的指示信息指示第三符号为第一资源对应的符号，网络设备确定第一资源对应的符号包括第三符号。基于该方案，可以实现网络设备根据资源配置信息确定的第一资源对应的符号中不包括参考信号所在的符号，同时使得网络设备和终端设备确定的第一资源对应的符号保持一致。
可选的，在该实现方式中，网络设备可以向终端设备发送第一指示信息。相应的，终端设备接收来自网络设备的第一指示信息。其中，第一指示信息包括偏置值，该偏置值标识第三符号和第四符号之间的间隔，该间隔的单位可以为符号，也可以为其他时域单位；或者，第一指示信息包括第四符号的位置信息。例如，基于上述图7a所示的示例，第一指示信息可以包括偏置值1，即指示第三符号和第四符号之间的间隔为1个符号；或者，第一指示信息可以包括子帧1的第3个符号的位置信息，例如，第3个符号的标识，指示将参考信号所在的符号由第4个符号调整至第3个符号。
其中，网络设备可以先确定第一资源对应的符号，再向终端设备发送第一指示信息，也可以先向终端设备发送第一指示信息，再结合第一指示信息和资源配置信息确定第一资源对应的符号，本申请实施例对此不做具体限定。
可选的，在该实现方式中，若第一时间单元包括的m个符号中包括第五符号，该第五符号为参考信号所在的符号，且第五符号对应的指示信息指示第五符号不为第一资源对应的符号，本申请实施例提供的通信方法还包括：终端设备将参考信号所在的符号由第五符号调整至第六符号，该第五符号和第六符号之间的间隔等于第三符号和第四符号之间的间隔，且由第五符号调整至第六符号的调整方向与由第三符号调整至第四符号的调整方向一致，例如，若将参考信号所在的符号由第三符号向前调整至第四符号，则将参考信号所在的符号由第五符号向前调整至第六符号；若将参考信号所在的符号由第三符号向后调整至第四符号，则将参考信号所在的符号由第五符号向后调整至第六符号。
示例性的，基于图7a所示的示例，子帧1的第11个符号为参考信号所在的符号，且第11个符号对应的指示信息指示第11个符号不为第一资源对应的符号，则终端设备将参考信号所在的符号由第11个符号调整至第10个符号，如图7b所示，调整后的参考信号所在的符号为子帧1的第3个符号和第10个符号。
在该方案中，由于终端设备可以相应地将参考信号所在的符号由第五符号调整至第六符号，因此可以保证参考信号所在的至少两个符号之间的位置相当于调整之前保持不变，从而避免参考信号的位置发生跳变，进而保证信道估计可以采用一套滤波参数，降低信道估计的实现复杂度。
需要说明的是，在该实现方式中，网络设备也可以将第五符号调整至第六符号，使得网络设备和终端设备确定的参考信号所在的符号保持一致。
可选的，终端设备和网络设备在确定第一资源对应的符号后，后续在终端设备和网络设备之间进行数据传输时，终端设备和网络设备丢弃(或删除)第一资源对应的符号所承载的数据。也就是说，第一资源对应的符号在资源映射时计算在内但不用于数据传输。
需要说明的是，丢弃或者删除第一资源对应的符号所承载的数据应在数据传输之前进行，终端设备和网络设备在资源映射时将第一资源计算在内，但第一资源对应的符号所承载的数据被丢弃(或删除)，未用于数据传输。
示例性的，第一时间单元内有5个符号用于终端设备和网络设备的数据传输，其中第3个符号被配置为第一资源对应的符号，终端设备和网络设备在资源映射时将第一资源对应的符号计算在内，若资源映射的数据为{a，b，c，d，e}，且a，b，c，d，e依次被映射到该5个符号，则在数据传输前第一资源占用的第3个符号上的数据c被丢弃(或删除)，终端设备和网络设备实际传输的数据为{a，b，d，e}。
综上，基于本申请实施例提供的通信方法，在预留资源时，不将参考信号所在的符号作为第一资源对应的符号，因此网络设备不会在参考信号所在的符号进行其他终端设备的数据调度，从而可以避免终端设备对应的参考信号与其他终端设备的数据传输发生冲突，进而可以避免因冲突影响终端设备的信道估计性能以及其他终端设备的数据传输性能。
需要说明的是，本申请实施例中，终端设备和网络设备可以以第一时间单元为周期，根据上述资源配置信息确定每个第一时间单元内第一资源对应的符号。其中，每个第一时间单元的起始位置可根据帧号、子帧号、时隙号或者符号号中的至少一项确定。例如，第一时间单元的起始帧为满足SFN mod x＝0的帧，SFN为帧号，x为预设值，x为正整数。示例性的，如图8所示，图示中包括4个第一时间单元，若上述资源配置信息为“00010000010000”，则终端设备和网络设备根据该资源配置信息确定四个第一时间单元中每个第一时间单元内第一资源对应的符号。
需要说明的是，本申请实施例中，在包括多个第一时间单元的第二时间单元内，网络设备可以仅向终端设备发送一次资源配置信息，终端设备和网络设备可以根据该资源配置信息，确定该第二时间单元内第一资源对应的符号。
示例性的，网络设备可以向终端设备发送第二指示信息，该第二指示信息包括第二时间单元中包括的每个第一时间单元对应的指示信息，第一时间单元对应的指示信 息可以指示是否需要根据资源配置信息确定该第一时间单元内第一资源对应的符号。其中，每个第二时间单元的起始位置可根据帧号、子帧号、时隙号或者符号号中至少一项确定。比如第二时间单元的起始帧为满足SFN mod y＝0的帧，SFN为帧号，y为预设值，y为正整数。
例如，如图9所示，第二时间单元包括4个第一时间单元，4个第一时间单元对应的指示信息分别为“1001”，其中，“1”表示需要根据资源配置信息确定该第一时间单元内第一资源对应的符号，“0”表示不需要根据资源配置信息确定该第一时间单元内第一资源对应的符号，也就是说，表示该第一时间单元内不存在第一资源对应的符号，因此，终端设备和网络设备根据资源配置信息确定第二时间单元包括的第1个第一时间单元和第4个第一时间单元内第一资源对应的符号。
