Description

通信方法、设备及存储介质 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信方法、设备及存储介质。
背景技术
先听后说(listen before talk，简称LBT)技术是一种避免信道接入冲突的技术。当基站和终端设备之间需要进行数据传输时，发送数据的一方可以通过LBT技术监听周围是否存在干扰。只有在监测到周围没有干扰时，才会进行数据的传输。
LBT技术是采用请求发送(request to send，简称RTS)/允许发送(clear to send，简称CTS)握手的方式实现的。发送端在需要有数据发送时，首先发送RTS。接收端在接收到并能正确解码RTS后发送CTS。发送端在接收到CTS之后，一个RTS/CTS握手完成，此时，发送端可以向接收端发送数据。由于基站和终端设备之间的数据传输需要通过波束来完成，因此在进行数据传输时，需要确定相应的传输波束。
在5G新空口(new radio，简称NR)中，天线面板(panel)用于形成具有方向性的波束和空间接收滤波器。由于终端设备可以进行多天线面板的发射和接收，目前的握手方式会造成终端设备接收和反馈信息时无法对应到相应的连接波束，导致对终端设备造成信号干扰。

具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，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清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
为了便于理解，首先，对本申请所涉及的概念进行说明。
终端设备：可以为包含无线收发功能、且可以与网络设备配合为用户提供通讯服务的设备。具体地，终端设备可以指用户设备(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。例如，终端设备可以是蜂窝电话、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、可穿戴设备，未来5G网络或5G之后的网络中的终端设备等。
网络设备：网络设备可以是用于与终端设备进行通信的设备，例如，可以是全球移动通信系统(Global System for Mobile Communication，GSM)或码分多址(Code Division Multiple Access，CDMA)通信系统中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络或5G之后的网络中的网络侧设备或未来演进的公共陆地移动网络(Public Land Mobile Network，PLMN)网络中的网络设备等。
本申请实施例中涉及的网络设备也可称为无线接入网(Radio Access Network，RAN)设备。RAN设备与终端设备连接，用于接收终端设备的数据并发送给核心网设备。RAN设备在不同通信系统中对应不同的设备，例如，在2G系统中对应基站与基站控制器，在3G系统中对应基站与无线网络控制器(Radio Network Controller，RNC)，在4G系统中对应演进型基站(Evolutional Node B，eNB)，在5G系统中对应5G系统，如NR中的接入网设备(例如gNB，集中单元CU，分布式单元DU)。
波束：指的是由天线发射出来的电磁波的能量在空间中集中在某个区域的特性。
LBT：listen before talk，先听后说技术，一种避免信道接入冲突的技术。当终端设备和网络设备之间需要进行数据传输时，发送方通过LBT技术监听周围是否存在干扰，只有监测到周围没有干扰时，才会进行数据的传输。
RTS/CTS握手：一种LBT的实现方式。当目标发送方有数据发送时，首先向目标接收方发送RTS帧，目标接收方在接收到RTS帧并能正确解码RTS帧后，会向目标发送方发送CTS帧。目标发送方接收到CTS帧并能正确解码CTS帧后，一个RTS/CTS握手过程完成，此时目标发送方能够向目标接收方发送数据。非目标发送方和非目标接收方在接收到RTS或CTS后需要保持静默一段时间。
下面，结合图1，对本申请中的方法所适用的场景进行说明。
图1为本申请实施例提供的应用场景的示意图。请参见图1，包括网络设备11和终端设备12，网络设备11和终端设备12之间可以进行无线通信。
在网络设备11和终端设备12进行无线通信的过程中，可能设备网络设备11和终端设备12之间进行数据传输。而在进行数据传输之前，通常会采用LBT机制判断周围是否存在干扰，只有监测到周围没有干扰时，才会进行 数据的传输。
在高频系统中，LBT机制采用的是RTS/CTS握手的方式实现的。发送端在需要有数据发送时，首先发送RST。接收端在接收到并能正确解码RTS后发送CTS。发送端在接收到CTS之后，一个RTS/CTS握手完成，此时，发送端可以向接收端发送数据。
可以理解的是，本申请实施例的技术方案可应用于NR通信技术中，NR是指新一代无线接入网络技术，可以应用在未来演进网络，如未来第五代移动通信(the 5th Generation Mobile Communication，5G)系统中。本申请实施例中的方案还可以应用于无线保真(Wireless Fidelity，WIFI)和长期演进(Long Term Evolution，LTE)等其他无线通信网络中，相应的名称也可以用其他无线通信网络中的对应功能的名称进行替代。
本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对一些实现中RTS帧结构和CTS帧结构进行介绍。
图2为一种RTS帧结构示意图，如图2所示，RTS帧可用于取得介质的控制权，以便传输大型帧。RTS帧的帧大小是由RTS门限(RTS threshold)决定的。
在RTS帧结构中，包括帧控制(Frame Control)、持续时间(Duration)、接收端地址(Receiver Address，简称RA)、发送端地址(Transmitter Address，简称TA)和帧校验序列(frame check sequence，简称FCS)。
帧控制中，帧的subtype设定为1011，代表该帧为RTS帧。
持续时间中，由于RTS帧会试图预定介质使用权，供帧交换程序使用，因此RTS帧发送端必须计算RTS帧结束后还需要多少时间永远数据传输。传输所需要的微秒数经过计算后会置于持续时间位中。如果计算的结果不是整数，就会被修正为下一个整数微秒。
RA表示接收端地址，即接收RTS帧的工作站地址。
TA表示发送端地址，即RTS帧的发送端地址。
FCS让工作站得以检查所收到的帧的完整性，当帧送至无线界面时，会先计算FCS，然后再由RF或IR链路传送出去。接收端随后会为所收到的帧计算FCS，然后与记录在帧中的FCS作比较。
图3为一种CTS帧结构示意图，可选地，在目的客户端收到RTS帧后，会发送一个CTS报文，这样在该客户端覆盖范围内的所有设备都会在指定的时间内不发送数据。CTS帧会令附近的工作站保持沉默，从而获取介质的控制权。
如图3所示，在CTS帧结构中，包括帧控制(Frame Control)、持续时间(Duration)、接收端地址(Receiver Address，简称RA)和帧校验序列(FCS)。
可选地，CTS帧中的帧的subtype设定为1100，代表CTS帧。
CTS帧中的持续时间用于，在应答RTS时，CTS帧的发送端会以RTS帧的持续时间值作为持续时间的计算基准。RTS帧会为整个RTS-CTS-Frame-ACK交换过程预留介质使用时间。
CTS帧中的RA表示接收端地址，CTS帧的接收端即为RTS帧的发送端。
CTS帧中的FCS用于让工作站得以检查所收到的帧的完整性。
在5G系统中，由于可以进行多panel发射和接收，panel用以形成具有方向性的波束和空间接收滤波器。在图2和图3示例的RTS帧和CTS帧中，并没有相关的TRP和panel的信息，因此会造成终端设备接收和反馈信息无法对应到连接波束的问题。
本申请实施例提供一种通信方法，以解决上述问题。
图4为本申请实施例提供的通信方法的信令图，如图4所示，该方法可以包括：
S41，网络设备确定RTS帧，所述RTS帧中包括标识信息，所述标识信息用于指示所述网络设备和终端设备之间进行数据传输的第一波束。
当网络设备要向终端设备发送数据之前，会与终端设备之间进行RTS/CTS握手。首先，网络设备确定RTS帧，该RTS帧中包括标识信息，该标识信息用于指示网络设备和终端设备之间进行数据传输的第一波束。

网络设备在确定了RTS帧之后，就可以向终端设备发送该RTS帧，终端设备可以根据该RTS帧获取该标识信息。
S43，终端设备根据所述标识信息确定所述网络设备和所述终端设备之间进行数据传输的第一波束。
终端设备在获取该标识信息之后，由于该标识信息指示网络设备和终端设备之间进行数据传输的第一波束，因此终端设备根据该标识信息可以确定该第一波束，即终端设备能够对应到与网络设备的连接波束。在多panel连接的情况下，确定了第一波束之后，就能够避免来自于其他panel的信号干扰。
本申请实施例提供的通信方法，在网络设备向终端设备发送数据之前，先确定RTS帧，并向终端设备发送该RTS帧，该RTS帧中包括标识信息。终端设备接收该RTS帧之后，能够根据该表示信息确定网络设备和终端设备之间进行数据传输的第一波束。本申请实施例的方案，通过在RTS帧中添加标识信息，使得终端设备能够对应到与网络设备的连接波束，在多panel连接的情况下，避免来自于其他panel的信号干扰。
下面结合具体的实施例对本申请的方案进行详细介绍。
针对于在多panel连接的情况下，目前的握手方式会造成终端设备接收和反馈信息时无法对应到相应的连接波束，导致对终端设备造成信号干扰的问题，本申请实施例的方案是，通过在RTS帧中添加标识信息，从而指示网络设备和终端设备之间进行数据传输的第一波束，使得终端设备能够对应到与网络设备的连接波束，避免来自于其他panel的信号干扰。
可选地，该标识信息可以包括终端设备的天线面板的标识，也可以包括 网络设备的传输接收点的标识。
对应的，在确定了标识信息之后，根据该标识信息可以确定对应的第一波束。可选地，第一波束为以下至少一种：网络设备和天线面板进行数据传输的波束；网络设备和传输接收点进行数据传输的波束；网络设备和天线面板以及传输接收点进行数据传输的波束。可选地，上述天线面板为标识信息包括天线面板的标识时该天线面板的标识指示的天线面板，上述传输接收点为标识信息包括传输接收点的标识时该传输接收点的标识指示的天线面板。
图5为本申请实施例提供的一种RTS帧的结构示意图，如图5所示，与图2示意的RTS帧的结构相比，图5示意的RTS帧的结构，除了包括帧控制、持续时间、接收端地址、发送端地址和帧校验序列外，还包括标识信息。
该标识信息就是相对于目前的RTS帧的结构，新添加的部分，用于指示网络设备和终端设备之间进行数据传输的第一波束。
在RTS帧的结构中，包括多个组成部分。新添加的标识信息可以位于RTS帧中的任意部分。
在RTS帧中，包括至少一个网络设备地址域和/或至少一个终端设备地址域。如图5中所示，在RTS帧中包括一个接收端地址域和一个发送端地址域。由于该RTS帧是由网络设备发送给终端设备的，因此该RTS帧中的接收端地址域即为终端设备地址域，该RTS帧中的发送端地址域即为网络设备地址域。
可选地，该RTS帧中的标识信息可以位于该网络设备地址域中，即位于RTS帧中的发送端地址域中。
可选地，该RTS帧中的标识信息也可以位于该终端设备地址域中，即位于RTS帧中的接收端地址域中。
在终端设备接收到了网络设备发送的RTS帧后，由于该终端设备为网络设备的目标接收端，因此终端设备可以根据RTS帧确定对应的CTS帧，可选地，对应的CTS帧中也包括该标识信息。
图6为本申请提供的一种CTS帧的结构示意图，如图6所示，与图3示意的CTS帧的结构相比，图6示意的CTS帧的结构，除了包括帧控制、持续时间、接收端地址和帧校验序列外，还包括标识信息。
该标识信息就是相对于目前的CTS帧的结构，新添加的部分，用于指示网络设备和终端设备之间进行数据传输的第一波束。
在CTS帧的结构中，包括多个组成部分。新添加的标识信息可以位于CTS帧中的任意部分。
在CTS帧中，包括至少一个网络设备地址域。如图6中所示，在CTS帧中包括一个接收端地址域。由于该CTS帧是由终端设备发送给网络设备的，因此该CTS帧中的接收端地址域即为网络设备地址域。
可选地，该CTS帧中的标识信息可以位于该网络设备地址域中，即位于CTS帧中的接收端地址域中。
当终端设备向网络设备发送该CTS帧之后，网络设备可以从终端设备接收CTS帧，并从CTS帧中获取该标识信息。至此，网络设备和终端设备之间 的一个RTS/CTS握手完成。
在网络设备和终端设备之间的一个RTS/CTS握手完成之后，网络设备可以向终端设备发送下行数据，具体的，由于根据RTS/CTS握手确定了第一波束，因此，网络设备可以通过第一波束向终端设备发送下行数据。
终端设备可以从网络设备接收该下行数据，可选地，也可以通过该第一波束从网络设备接收该下行数据。
下面结合一个具体的示例对本申请的方案进行介绍。
图7为本申请实施例提供的多panel下的RTS/CTS握手示意图，如图7所示，包括终端设备71、网络设备72和WIFI设备73。
在图7的示例中，终端设备71可配置多panel，例如panel1和panel2，从而形成两个连接波束，即图7中的接收波束701和接收波束702，分别接收网络设备72和WIFI设备73的数据。
当接收波束701和接收波束702之间的隔离度或者空间位置隔离较远时，终端设备71可在不受干扰的情况下同时接收网络设备72和WIFI设备73的数据，例如通过与网络设备72之间的数据传输进行打电话，通过与WIFI设备73之间的数据传输进行上网，等等。
当接收波束701和接收波束702之间的距离较近或者隔离度较小，例如终端设备71的位置移动之后导致上述情况发生时，此时波束703和波束704之间可能产生干扰。
当网络设备72要向终端设备发送下行数据时，首先通过波束703向终端设备71发送RTS帧，该RTS帧中不仅包括终端设备地址域，还包括接收波束702的标识信息，例如可以为panel2的标识。
此时，如果接收波束701和接收波束702之间的隔离度不高，终端设备71会通过接收波束701接收到波束703的RTS帧。由于RTS帧中包括panel2的标识，因此可以根据panel2的标识获知该RTS帧是传输该panel2的，此时panel1会保持静默而不发送任何数据，以避免对panel1的连接产生干扰。
本申请实施例提供的通信方法，在网络设备向终端设备发送数据之前，先确定RTS帧，并向终端设备发送该RTS帧，该RTS帧中包括标识信息。终端设备接收该RTS帧之后，能够根据该表示信息确定网络设备和终端设备之间进行数据传输的第一波束。本申请实施例的方案，通过在RTS帧中添加标识信息，使得终端设备能够对应到与网络设备的连接波束，在多panel连接的情况下，避免来自于其他panel的信号干扰。

虽然上述以LTE系统为例进行了介绍，但本领域技术人员应当知晓，本申请不仅仅适用于LTE系统，也可以适用于其他无线通信系统，例如GSM、CDMA2000、WCDMA、TD-SCDMA以及未来新的网络系统等，此处不做限定。
为了更好理解本申请各个实施例，可参考上述移动终端硬件结构以及通信网络系统。
上述本申请实施例序号仅仅为了描述，不代表实施例的优劣。
在本申请中，对于相同或相似的术语概念、技术方案和/或应用场景描述，一般只在第一次出现时进行详细描述，后面再重复出现时，为了简洁，一般未再重复阐述，在理解本申请技术方案等内容时，对于在后未详细描述的相同或相似的术语概念、技术方案和/或应用场景描述等，可以参考其之前的相关详细描述。
在本申请中，对各个实施例的描述都各有侧重，某个实施例中没有详述或记载的部分，可以参见其它实施例的相关描述。
本申请技术方案的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本申请记载的范围。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到上述实施例方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本申请的 技术方案本质上或者说对现有技术做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在如上的一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，被控终端，或者网络设备等)执行本申请每个实施例的方法。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
