Description

通信方法、装置、设备及存储介质
本申请要求于2018年03月26日提交中国专利局、申请号为201810254840.9、申请名称为“通信方法、装置、设备及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法、装置、设备及存储介质。
背景技术
新一代无线(New Radio，NR)标准中定义了同步脉冲序列集(Synchronization Signal burst set，SS burst set)，其主要用于终端进行初始接入、系统消息更新以及波束(beam)管理等。通常每个SS burst set的持续时间为5毫秒(millisecond，ms)，周期可以为5、10、20、40、80或100ms等。图1示出了SS burst set一种可能的结构，SS burst set由若干个同步信号块(Synchronization Sigal Block，SSB)组成。SSB是一种信号结构，适用于5G以及之后的通信系统中。同步信号块还可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)，或者还可以有其他名称，本申请对此不做限制。同步信号块一般可以包括主同步信号(Primary Synchronization Sigal，PSS)、辅同步信号(Secondary Synchronization Signal，SSS)以及物理广播信道(Physical Broadcast Channel，PBCH)。在图1的示例中，每个SSB持续4个正交频分复用技术(Orthogonal Frequency Division Multiplexing，OFDM)符号。PSS和SSS主要作用是帮助终端识别小区以及和小区进行同步，PBCH则包含了最基本的系统信息例如系统帧号、帧内定时信息等。终端成功接收同步信号块是其接入该小区的前提。当载波频率小于6GHz时，每个SS burst set最多包含8个SSB；当载波频率大于6GHz时，每个SS burst set最多包含64个SSB。每个SSB可以对应于不同的beam方向。
对于授权频段(licensed band)来讲，网络设备为SS burst set配置时频资源，即SS burst set的配置发送时间固定。然而在非授权频段(unlicensed band)上，通常采用先听后说(Listen Before Talk，LBT)的信道竞争接入机制，由于LBT的影响，网络设备可能不能在SS Burst Set的配置发送时间发送SS Burst Set，当终端还是按照该配置发送时间进行速率匹配时，可能无法准确获取下行数据的时频资源，从而无法准确解析下行数据，进而降低了通信系统的可靠性。

具体实施方式
在非授权频段(unlicensed band)上，通常采用LBT的信道竞争接入机制。图2为本申请一实施例提供的基于LTB机制的SS burst set的发送方式的示意图，如图2所示，标准可以定义若干SS burst set发送窗口，当网络设备在SS burst set的配置发送时间无法发送SS burst set时，会在该配置发送时间之后的SS burst set发送窗口尝试发送SS burst set；图3为本申请另一实施例提供的基于LTB机制的SS burst set的发送方式的示意图，如图3所示，标准可以定义一个大的SS burst set发送窗口，当网络设备在SS burst set的配置发送时间无法发送SS burst set时，可以在LBT通过后的任意时刻开始发送SS burst set。总之，由于LBT的影响，网络设备可能不能在SS Burst Set的配置发送时间发送SS Burst Set，当终端还是按照该配置发送时间进行速率匹配时，可能无法准确获取下行数据的时频资源，从而无法准确解析下行数据，进而降低了通信系统的可靠性。
为了解决上述技术问题，本申请提供一种通信方法、装置、设备及存储介质。图4为本申请一实施例提供的本申请技术方案的应用场景图，为清楚起见，图4中只示 出了一个终端10和一个网络设备20，实际上还可以包括更多的终端10和网络设备20，其中终端10和网络设备20通过无线接口实现通信。
需要说明的是，本申请中涉及的网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)或者增强的长期演进(evolved Long Term Evolution，eLTE)中的演进型基站(evolved NodeB，eNB)，或者是下一代演进型基站(next generation-evolved NodeB，ng-eNB)、还可以是WLAN中的接入点(Access Point，AP)或者中继站，也可以是NR中的gNB等，在此不作限定。
另外，本申请中涉及的终端可以是指向用户提供语音和/或数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其它处理设备，终端还可以被称为“终端设备”。该终端可以经无线接入网(Radio Access Network，RAN)与至少一个核心网进行通信。该终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和带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音和/或数据。终端也可以称为用户单元(Subscriber Unit)、用户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile Station)、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)或用户设备(User Equipment)，在此不作限定。
实施例一
基于图4的应用场景，进一步地，本实施例提供的通信方法可适用于如下场景，网络设备通过一个天线在第一载波上发送SS burst set，或者，网络设备通过多个天线在第一载波上发送SS burst set，所述多个天线中的各天线在每个时刻的LBT状态相同，例如：所述多个天线中的各天线在某个时刻均已通过LBT，或者在某个时刻均未通过LBT。需要说明的是，本申请所述的天线可以是天线面板。
图5为本申请一实施例提供的一种通信方法的交互流程图，如图5所示，该方法包括如下步骤：
步骤S501：网络设备在第一载波进行LBT，当通过LBT时确定第一时间偏移。
步骤S502：网络设备向终端发送第一时间偏移。
步骤S503：终端接收第一时间偏移，并根据第一时间偏移在第一载波进行速率匹配。
针对步骤S501进行说明：
在非授权频段的应用场景下，网络设备在第一载波上先进行LBT，以发送第一SS burst set。其中，第一SS burst set包含了1个或者多个SSB，网络设备通过同一天线或多个天线发送这些SSB，如上所述，当通过多个天线发送各SSB时，各天线的LBT状态始终保持一致。以网络设备在第一载波上进行LBT为例，当网络设备在第一载波未通过LBT时，则无法发送第一SS burst set，需要待下一个周期再启动 LBT。当网络设备在第一载波通过LBT时，可以发送第一SS burst set。由于LBT本身需要耗费一定的时间，可以理解的是，网络设备需要通过LBT才能发送第一SS burst set，会导致第一SS burst set的实际发送时间与第一SS burst set的配置发送时间存在偏移(offset)。所谓“第一SS Burst Set的配置发送时间”是指网络设备为第一SS Burst Set配置的发送时间。
当通过LBT时，网络设备确定上述第一时间偏移，该第一时间偏移为第一SS burst set在第一载波上的实际发送时间相对于第一SS burst set的配置发送时间的时间偏移。示例性地，在其他实施例中，该第一时间偏移还可以为第一SS burst set中一个或多个SSB在第一载波上的实际发送时间相对于该第一SS burst set中一个或多个SSB的配置发送时间的时间偏移。
可选地，假设第一时间偏移的长度为X比特，则第一时间偏移的最大值为
Figure PCTCN2019079565-appb-000004
个SSB的时间长度，以SSB持续4个OFDM符号为例，这种情况下，SSB的时间长度为4个OFDM符号。需要说明的是SSB的时间长度不限于4个OFDM符号。进一步地，M表示第一SS Burst Set的最大时间偏移，该最大时间偏移是指网络设备为第一SS Burst Set配置的最大时间偏移，N表示第一SS Burst Set的时间长度，通常M和N的单位均为毫秒(millisecond，ms)，2 K表示所述网络设备和所述终端所属的通信系统在一个SS Burst Set窗口所支持的SSB的最大传输个数。例如：X，K均为6，M、N均为5ms，则第一时间偏移为1个SSB的时间长度。
进一步地，本实施例通过如下示例说明如何确定第一时间偏移：
图6A至图6D为本申请实施例提供的基于LTB机制的第一SS burst set的多种发送方式的示意图，该发送方式也可以体现为“图样(pattern)”的形式。其中，第一SS burst set可以包括4个、8个或64个SSB等。本申请实施例以第一SS burst set包括4个SSB(SSB1、SSB2、SSB3和SSB4)为例，第一SS burst set包括8个或64个SSB等情况可参考包括4个SSB的情况。
具体地，如图6A所示，在SSB3的配置发送时间及其之前网络设备在第一载波还未通过LBT，在SSB4的配置发送时间网络设备在第一载波已通过LBT。因此网络设备在SSB4的配置发送时间正常发送SSB4，接着在下一个SS burst set窗口发送剩余的SSB，如在该示例中发送SSB1、SSB2和SSB3，这种情况下第一时间偏移为SSB4的配置发送时间与SSB1的配置发送时间之差。
如图6B所示，在SSB3的配置发送时间及其之前网络设备在第一载波还未通过LBT，在SSB4的配置发送时间网络设备在第一载波已通过LBT，这时网络设备从SSB4的配置发送时间开始，依次发送所有的SSB，如在该示例中发送SSB1、SSB2、SSB3和SSB4，这种情况下，第一时间偏移为SSB1的实际发送时间与SSB1的配置发送时间之差。
如图6C所示，在SSB4的发送时间及其之前网络设备在第一载波还未通过LBT，而在SS burst set的配置发送时间之后的第二个SS burst set发送窗口网络设备在第一载波已通过LBT，这种情况下，第一时间偏移为SSB1的实际发送时间与SSB1的配置发送时间之差。
如图6D所示，在SSB4的发送时间及其之前网络设备在第一载波还未通过LBT，而在SS burst set的配置发送时间之后的第二SS burst set发送窗口的SSB3的发送时间网络设备在第一载波已通过LBT，这种情况下，第一时间偏移为SSB3的实际发送时间与SSB1的配置发送时间之差。
针对步骤S502进行说明：网络设备向终端发送第一时间偏移，包括：网络设备向终端发送下行控制信息(Downlink Control Information，DCI)，其中第一时间偏移可以携带在该DCI中，该DCI可以是UE特定DCI(UE-specific DCI)或公共DCI(group-common DCI)，本申请对网络设备如何发送第一时间偏移不做限制。
针对步骤S503进行说明：终端接收来自网络设备的第一时间偏移，并根据第一时间偏移进行速率匹配。所谓“速率匹配”(Rate matching)是指传输信道上的比特被重发(repeated)或者被打孔(punctured)，以匹配物理信道的承载能力，信道映射时达到传输格式所要求的比特速率。在本申请中，网络设备可以向终端发送DCI，该DCI用于指示下行数据的配置发送时间以及第一SS Burst Set的配置发送时间；终端根据获取到的第一时间偏移、下行数据的配置发送时间以及第一SS Burst Set的配置发送时间可以确定所述下行数据的实际发送时间，从而对下行数据进行解码。其中，该下行数据可以为物理下行共享信道(Physical Downlink Shared Channel，PDSCH)数据、信道状态信息-参考信号(Channel State Information-Reference Signals，CSI-RS)或者跟踪参考信号(Tracking Reference signal，TRS)。“下行数据的配置发送时间”是指网络设备为所述下行数据配置的发送时间。
具体地，上述速率匹配过程的前提是网络设备和终端已默认第一SS Burst Set的一种发送方式。例如：默认的第一SS Burst Set的发送方式可以如图6A所示，第一天线在SSB4的配置发送时间正常发送SSB4，接着在下一个SS burst set窗口发送SSB1、SSB2和SSB3。或者，如图6B所示，第一天线从SSB4的配置发送时间开始，依次发送SSB1、SSB2、SSB3和SSB4。
终端设备的速率匹配过程具体如下：图7A为本申请一实施例提供的基于图6A对应的第一SS Burst Set和下行数据的实际发送时间的示意图，如图7A所示，当第一SS Burst Set存在第一时间偏移时，终端根据第一SS Burst Set的配置发送时间和第一时间偏移确定第一SS Burst Set的实际发送时间，假设网络设备规定其发送完第一SS Burst Set之后，立即发送下行数据，即第一SS Burst Set和下行数据的实际发送时间相邻，基于此，终端设备可确定下行数据的实际发送时间，从而准确解析下行数据。图7B为本申请一实施例提供的基于图6B对应的第一SS Burst Set和下行数据的实际发送时间的示意图，如图7B所示，当第一SS Burst Set存在第一时间偏移时，终端根据第一SS Burst Set的配置发送时间和第一时间偏移确定第一SS Burst Set的实际发送时间，由于网络设备规定其发送完第一SS Burst Set之后，立即发送下行数据，可知，下行数据的实际发送时间与第一SS Burst Set的实际发送时间相邻。基于此，终端设备可确定下行数据的实际发送时间，从而准确解析下行数据。需要说明的是，由于图6A和图6B所示的第一SS Burst Set的发送方式不同，基于此，确定的下行数据的实际发送时间也不尽相同。
当网络设备和终端未默认第一SS Burst Set的发送方式时，网络设备还需要向终 端发送发送方式指示信息，该发送方式指示信息用于指示第一SS burst set的发送方式，例如该发送方式指示信息用于指示网络设备采用如图6A所示的发送方式或如图6B所示的发送方式。基于此，终端确定了第一SS burst set的发送方式之后，终端根据第一SS Burst Set的配置发送时间和第一时间偏移确定第一SS Burst Set的实际发送时间，假设网络设备规定其发送完第一SS Burst Set之后，立即发送下行数据，即第一SS Burst Set和下行数据的实际发送时间相邻。例如：当终端根据该发送方式指示信息确定第一SS burst set的发送方式为图6A的发送方式时，终端确定下行数据的实际发送时间如图7A所示。当终端根据该发送方式指示信息确定第一SS burst set的发送方式为图6B的发送方式时，终端确定下行数据的实际发送时间如图7B所示。
综上，本申请提供一种通信方法，包括：网络设备在第一载波进行LBT，当通过LBT时确定第一时间偏移；网络设备向终端发送第一时间偏移；终端接收第一时间偏移，并根据第一时间偏移进行速率匹配，其中该第一时间偏移为第一SS burst set在第一载波上的实际发送时间相对于第一SS burst set的配置发送时间的时间偏移。通过该方法使得终端可以根据第一时间偏移确定第一SS burst set的实际发送时间，以进行速率匹配，并准确地解析下行数据，从而提高了通信系统的可靠性。
实施例二
实施例一是以单载波为例对通信方式进行了说明，实际上，本申请还存在多载波应用场景，如第一载波为主信道，对应的第一SS burst set用于随机接入，信道测量反馈等；第二载波为辅信道，对应的第二SS burst set用于信道测量反馈。其中，第二载波可以是终端设备和网络设备默认的用于传输第二SS burst set的载波，或者，网络设备在发送SS burst set之前，网络设备向终端设备发送载波指示信息，该载波指示信息用于指示用于传输第二SS burst set的载波为第二载波。下面将介绍基于多载波的通信方法。具体地，以实施例一为基础，图8为本申请一实施例提供的一种通信方法的交互流程图，如图8所示，该方法还包括：
步骤S801：网络设备在第二载波进行LBT，当通过LBT时确定第二时间偏移。
步骤S802a：若第二时间偏移与第一时间偏移具有第一预设关系，则网络设备不发送第二时间偏移。
步骤S803a：终端根据第一时间偏移在第二载波进行速率匹配。
步骤S802b：若第二时间偏移与第一时间偏移不具有第一预设关系，则网络设备发送第二时间偏移。
步骤S803b：终端接收第二时间偏移，并根据第二时间偏移在第二载波进行速率匹配。
其中，步骤S802a和步骤S803a构成的方案与步骤S802b和步骤S803b构成的方案为并列方案。需要说明的是，步骤S802a和步骤S803a构成的方案与步骤S802b和步骤S803b构成的方案是可选的。
步骤S802a至步骤S803b可在步骤S502之后执行，而本实施例对步骤S801与步骤S502的先后顺序不做限制，图8以步骤S801在步骤S503之后执行为例。
针对步骤S801进行说明：第二载波用于发送第二SS Burst Set，第二时间偏移为第二SS Burst Set在第二载波上的实际发送时间相对于第二SS Burst Set的配置发送 时间的时间偏移。示例性地，在其他实施例中，该第二时间偏移还可以为第二SS burst set中一个或多个SSB在第一载波上的实际发送时间相对于该第二SS burst set中一个或多个SSB的配置发送时间的时间偏移。需要说明的是，步骤S801与步骤S501类似，具体可参考步骤S501，本申请对此不再赘述。
结合步骤S802a和步骤S803a进行说明：例如：第一预设关系为第二时间偏移与第一时间偏移相同，或者，第一预设关系为第一时间偏移与第二时间偏移之间具有固定时间间隔。这种情况下，网络设备无需发送第二时间偏移，当第二时间偏移与第一时间偏移相同时，终端仅需要根据第一时间偏移确定第二SS Burst Set的实际发送时间，以准确地进行第二载波的速率匹配。当第二时间偏移与第一时间偏移之间具有固定时间间隔时，终端仅需要根据第一时间偏移和所述固定时间间隔确定第二SS Burst Set的实际发送时间，以准确地进行第二载波的速率匹配。其中，终端设备在第二载波上的速率匹配过程可参考步骤S503，本申请对此不再赘述。
结合步骤S802b和步骤S803b进行说明：需要说明的是，若第二时间偏移与第一时间偏移不具有第一预设关系，则网络设备向终端发送第二时间偏移。终端可以根据第二时间偏移确定第二SS Burst Set的实际发送时间，以准确地进行速率匹配。其中，终端设备在第二载波上的速率匹配过程可参考步骤S503，本申请对此不再赘述。
综上，在本实施例中，若第二时间偏移与第一时间偏移具有第一预设关系，则网络设备向终端不发送第二时间偏移，以使终端实现速率匹配，从而可以节省系统信令开销。
实施例三
基于图4的应用场景，进一步地，本实施例提供的通信方法可适用于如下场景，网络设备通过多个天线在第一载波上发送SS burst set，所述多个天线中的各天线在每个时刻的LBT状态不一定相同，例如：所述多个天线中的某些天线在某个时刻已通过LBT，而其余天线在该时刻未通过LBT。具体地，图9为本申请一实施例提供的一种通信方法的交互流程图，如图9所示，该方法包括如下步骤：
步骤S901：网络设备的多个第一天线在第一载波进行LBT，当至少一个第一天线通过LBT时网络设备确定第一时间偏移。
步骤S902：网络设备向终端发送第一时间偏移。
步骤S903：终端接收第一时间偏移，并根据第一时间偏移在第一载波进行速率匹配。
针对步骤S901进行说明：
其中，多个第一天线用于在第一载波上发送第一SS Burst Set的各SSB。例如：图10为本申请一实施例提供的各第一天线与各SSB的对应关系示意图，如图10所示，所述多个第一天线分别为第一天线1和第一天线2，且第一天线1用于发送SSB1和SSB2，第一天线2用于发送SSB3和SSB4。其中，各第一天线与各SSB的对应关系可以通过剩余系统信息(Remaining system information，RMSI)、开放式系统互联(Open System Interconnection，OSI)信令或者无线资源控制(Radio Resource Control，RRC)信令配置，该RRC信令可以是UE专用RRC信令(UE-specific  RRC)，或者是公共RRC(common RRC)。
进一步地，第一时间偏移为第一SS Burst Set在第一载波上的实际发送时间相对于第一SS Burst Set的配置发送时间的时间偏移。
在非授权频段的应用场景下，网络设备的多个第一天线在第一载波上先进行LBT，以发送第一SS burst set。其中，第一SS burst set包含多个SSB，网络设备可以通过不同的第一天线分别发送这些SSB。以某第一天线在第一载波上进行LBT为例，当该第一天线在第一载波未通过LBT时，则无法发送SSB，需要待载波空闲时继续/重启LBT。当该第一天线在第一载波通过LBT时，可以发送SSB。由于LBT本身需要耗费一定的时间，可以理解的是，各第一天线需要通过LBT才能发送SSB，因此会导致第一SS burst set的实际发送时间与第一SS burst set的配置发送时间存在偏移(offset)。所谓“第一SS Burst Set的配置发送时间”是指网络设备为第一SS Burst Set配置的发送时间。
可选地，假设第一时间偏移的长度为X比特，则第一时间偏移的最大值为
Figure PCTCN2019079565-appb-000005
个SSB的时间长度，以SSB持续4个OFDM符号为例，这种情况下，SSB的时间长度为4个OFDM符号。需要说明的是SSB的时间长度不限于4个OFDM符号。进一步地，M表示第一SS Burst Se t的最大时间偏移，该最大时间偏移是指网络设备为第一SS Burst Set配置的最大时间偏移，N表示第一SS Burst Set的时间长度，通常M和N的单位均为毫秒(millisecond，ms)，2 K表示所述网络设备和所述终端所属的通信系统在一个SS Burst Set窗口所支持的SSB的最大传输个数。例如：X，K均为6，M、N均为5ms，则第一时间偏移为1个SSB的时间长度。
进一步地，本实施例通过如下示例说明如何确定第一时间偏移：
例如：图11A为本申请一实施例提供的基于LTB机制的第一SS burst set的发送方式的示意图，如图11A所示，第一天线1和第一天线2分别在第一载波上选择一个随机数并进行退避，第一天线1需要经过4个空闲的退避时隙(idle ECCA slot)才能完成退避，第一天线2需要经过6个空闲的退避时隙(idle ECCA slot)才能完成退避，在第一天线1实现了4个空闲的退避时隙之后，第一天线1处于等待状态，以等待第一天线2完成6个空闲的退避时隙，进一步地，第一天线1和第二天线2在完成退避之后需要执行25微秒的下行传输信道的侦听(Performing channel sensing for an interval of 25us prior to downlink transmission)，来确定第一载波是否空闲；当确定第一载波空闲时，第一天线1和第一天线2可以同时在第一载波上进行SSB的传输。这种情况下，网络设备可以确定第一天线1和第一天线2均已通过LBT时的时间，并计算该时间与第一SS Burst Set的配置发送时间之差，并确定一个大于或等于该时间差的值作为第一时间偏移。
图11B为本申请另一实施例提供的基于LTB机制的SS burst set的发送方式的示意图，如图11B所示，第一天线1和第一天线2分别在第一载波上进行退避，第一天线1需要经过4个空闲的退避时隙(idle ECCA slot)才能完成退避，天线2需要经过6个空闲的退避时隙(idle ECCA slot)才能完成退避，第一天线1和第一天线2的退避过程相互独立，其中第一天线1在进行SSB传输之前需要执行25微秒的下行传输信道的侦听(Performing channel sensing for an interval of 25us prior to downlink  transmission)，来确定第一载波是否空闲，当确定第一载波空闲时，第一天线1可以在第一载波上进行SSB传输。在第一天线2实现了6个空闲的退避时隙之后，第一天线2在进行SSB传输之前需要执行25微秒的下行传输信道的侦听(Performing channel sensing for an interval of 25us prior to downlink transmission)，来确定第一载波是否空闲，当确定第一载波空闲时，第一天线2可以在第一载波上进行SSB传输。这种情况下，网络设备可以确定第一天线1已通过LBT时的时间，计算该时间与第一SS Burst Set的配置发送时间之差，并确定一个大于或等于该时间差的值作为第一时间偏移。或者，网络设备可以确定第一天线2已通过LBT时的时间，计算该时间与第一SS Burst Set的配置发送时间之差，并确定一个大于或等于该时间差的值作为第一时间偏移。或者，网络设备可以分别确定第一天线1和第一天线2已通过LBT时的时间，选择这两个时间中的较大者，计算该较大时间与第一SS Burst Set的配置发送时间之差，并确定一个大于或等于该时间差的值作为第一时间偏移。
针对步骤S902进行说明：网络设备向终端发送第一时间偏移，包括：网络设备向终端发送DCI，其中第一时间偏移可以携带在该DCI中，该DCI可以是UE特定DCI(UE-specific DCI)或公共DCI(group-common DCI)，本申请对网络设备如何发送第一时间偏移不做限制。
针对步骤S903进行说明：终端接收来自网络设备的第一时间偏移，并根据第一时间偏移进行速率匹配。所谓“速率匹配”(Rate matching)是指传输信道上的比特被重发(repeated)或者被打孔(punctured)，以匹配物理信道的承载能力，信道映射时达到传输格式所要求的比特速率。在本申请中，网络设备可以向终端发送DCI，该DCI用于指示下行数据的配置发送时间以及第一SS Burst Set的配置发送时间；终端根据获取到的第一时间偏移、下行数据的配置发送时间以及第一SS Burst Set的配置发送时间可以确定所述下行数据的实际发送时间，从而对下行数据进行解码。其中，该下行数据可以为PDSCH数据、CSI-RS或者RS。“下行数据的配置发送时间”是指网络设备为所述下行数据配置的发送时间。
具体地，上述速率匹配过程的前提是网络设备和终端已默认第一SS Burst Set的一种发送方式。当网络设备和终端未默认第一SS Burst Set的发送方式时，网络设备还需要向终端发送发送方式指示信息，该发送方式指示信息用于指示第一SS burst set的发送方式。
综上，本申请提供一种通信方法，包括：网络设备的多个第一天线在第一载波进行LBT，当至少一个第一天线通过LBT时网络设备确定第一时间偏移。网络设备向终端发送第一时间偏移。终端根据第一时间偏移在第一载波进行速率匹配。其中该第一时间偏移为第一SS burst set在第一载波上的实际发送时间相对于第一SS burst set的配置发送时间的时间偏移。通过该方法使得终端可以根据第一时间偏移确定第一SS burst set的实际发送时间，以进行速率匹配，并准确地解析下行数据，从而提高了通信系统的可靠性。
实施例四
以实施例三为基础，进一步地，所述通信方法还包括：当所述多个第一天线的LBT状态不一致时，网络设备发送第一SS Burst Set的部分SSB，其中，LBT状态为 通过LBT或未通过LBT。更进一步地，若第二天线对应的SSB未被成功发送，则网络设备通过第二天线对应的SSB的时频资源向终端发送下行数据，其中，该第二天线为任一个第一天线。具体地，以下行数据为PDSCH数据为例，图12A至图12C为本申请一实施例提供的SSB以及PDSCH数据的发送方式的示意图，如图12A所示，第一天线1用于发送SSB1和SSB2，第一天线2用于发送SSB3和SSB4，由于在SSB2的配置发送时间及其之前第一天线1未通过LBT，因此，第一天线1延后发送SSB1和SSB2；同样，由于在SSB4的配置发送时间及其之前第一天线2未通过LBT，因此，第一天线2延后发送SSB3和SSB4，而网络设备可以通过网络设备为SSB1、SSB2、SSB3和SSB4配置的时频资源发送PDSCH数据，即网络设备在为SSB1、SSB2、SSB3和SSB4配置的时频资源上打孔，通过这些时频资源发送PDSCH数据。
如图12B所示，由于在SSB2的配置发送时间及其之前第一天线1未通过LBT，因此，第一天线1延后发送SSB1和SSB2，而在SSB4的配置发送时间及其之前第一天线2已通过LBT，因此，第一天线2在SSB3和SSB4的配置发送时间正常发送SSB3和SSB4，而网络设备可以通过网络设备为SSB1和SSB2配置的时频资源发送PDSCH数据，即网络设备在为SSB1、SSB2配置的时频资源上打孔，通过这些时频资源发送PDSCH数据。
如图12C所示，在SSB2的配置发送时间及其之前第一天线1已通过LBT，因此，第一天线1在SSB1和SSB2的配置发送时间正常发送SSB1和SSB2；而由于在SSB4的配置发送时间及其之前第一天线2未通过LBT，因此，第一天线2延后发送SSB3和SSB4，而网络设备可以通过网络设备为SSB3和SSB4配置的时频资源发送PDSCH数据，即网络设备在为SSB3和SSB4配置的时频资源上打孔，通过这些时频资源发送PDSCH数据。
基于此，哪些SSB已发送，哪些SSB未发送对于速率匹配过程来讲至关重要。基于此，在本申请中，图13为本申请另一实施例提供的一种通信方法的交互流程图，如图13所示，该通信方法包括如下步骤：
步骤S1301：网络设备根据多个第一天线的LBT状态确定第一时间偏移。
步骤S1302：网络设备向终端发送第一时间偏移。
其中，步骤S1301与步骤S901类似，步骤S1302与步骤S902类似，具体内容可参考步骤S901和步骤S902，本申请对此不再赘述。
步骤S1303：网络设备向终端发送第一指示信息。
其中，步骤S1303也可以在步骤S1302之前执行，或者可以与步骤S1302并行执行，本申请对步骤S1302和步骤S1303之间的顺序不做限制。
步骤S1304：终端接收第一时间偏移和第一指示信息，并根据第一指示信息和第一时间偏移在第一载波上进行速率匹配。
其中，第一指示信息用于指示所述多个第一天线在发送所述第一SS Burst Set的各SSB时分别是否通过LBT。基于此，终端可以根据第一指示信息确定第一SS Burst Set中的哪个SSB成功发送，哪个SSB未成功发送，并进行速率匹配。例如：第一指示信息的长度为2比特，例如：第1个比特表示第一天线1在发送SSB1和 SSB2时是否通过LBT，第2个比特表示第一天线2在发送SSB3和SSB4时是否通过LBT。由此可知，网络设备通过第一指示信息可以确定哪些SSB被成功发送，哪些SSB未被成功发送。
或者，第一指示信息用于指示第一SS Burst Set的SSB是否被成功发送。例如：第一指示信息包括2比特，第1个比特表示SSB1和SSB2是否被成功发送，第2个比特表示SSB3和SSB4是否被成功发送。
进一步地，上述第一指示信息可以携带在DCI中，该DCI可以是UE-specific DCI或group-common DCI，本申请对网络设备如何发送第一指示信息不做限制。
上述第一指示信息的长度为Y比特，所述Y比特中每个比特用于指示
Figure PCTCN2019079565-appb-000006
个第一天线的LBT状态，Z表示所述多个第一天线的数量。
针对步骤S1304进行说明：如上所述，若第二天线对应的SSB未被成功发送，则网络设备通过第二天线对应的SSB的时频资源向终端发送下行数据。因此，终端在进行速率匹配时，通过第一指示信息可以确定哪个SSB的时频资源用于发送下行数据。
在本申请实施例中，第一指示信息用于指示所述多个第一天线在发送所述第一SS Burst Set的各SSB时分别是否通过LBT，或者指示第一SS Burst Set的各SSB是否被成功发送。从而使得终端根据该第一指示信息可以确定哪些SSB已被成功发送，而哪些SSB未被成功发送，以精确地实现速率匹配，从而提高通信系统的可靠性。
实施例五
在实施例三和实施例四中，均以单载波为例，实际上，本申请还存在多载波应用场景，如第一载波为主信道，对应的第一SS burst set用于随机接入，信道测量反馈等；第二载波为辅信道，对应的第二SS burst set用于信道测量反馈。下面将介绍基于多载波的通信方法。具体地，以实施例一或实施例二为基础，图14为本申请一实施例提供的一种通信方法的交互流程图，如图14所示，该方法包括：
步骤S1401：网络设备的多个第三天线在第二载波进行LBT，当至少一个第三天线通过LBT时网络设备确定第二时间偏移。
步骤S1402a：若第二时间偏移与第一时间偏移具有第一预设关系，则网络设备不发送第二时间偏移。
步骤S1403a：终端根据第一时间偏移在第二载波进行速率匹配。
步骤S1402b：若第二时间偏移与第一时间偏移不具有第一预设关系，则网络设备发送第二时间偏移。
步骤S1403b：终端接收第二时间偏移，并根据第二时间偏移在第二载波进行速率匹配。
其中，步骤S1402a和步骤S1403a构成的方案与步骤S1402b和步骤S1403b构成的方案为并列方案。需要说明的是，步骤S1402a和步骤S1403a构成的方案与步骤S1402b和步骤S1403b构成的方案是可选的。
步骤S1402a至步骤S1403b可在步骤S1302之后执行，而本实施例对步骤S1401 与步骤S1302的先后顺序不做限制，图14以步骤S1401在步骤S1304之后执行为例。
针对步骤S1401进行说明：多个第三天线用于发送第二SS Burst Set的各SSB，所述第二时间偏移为所述第二SS Burst Set在所述第二载波上的实际发送时间相对于所述第二SS Burst Set的配置发送时间的时间偏移。需要说明的是，步骤S1401与步骤S501类似，具体可参考步骤S501，本申请对此不再赘述。
结合步骤S1402a和步骤S1403a进行说明：例如：第一预设关系为第二时间偏移与第一时间偏移相同，或者，第一时间偏移与第二时间偏移之间具有固定时间间隔。这种情况下，网络设备无需发送第二时间偏移，当第二时间偏移与第一时间偏移相同时，终端仅需要根据第一时间偏移确定第二SS Burst Set的实际发送时间，以准确地进行第二载波的速率匹配。当第二时间偏移与第一时间偏移之间具有固定时间间隔时，终端仅需要根据第一时间偏移和所述固定时间间隔确定第二SS Burst Set的实际发送时间，以准确地进行第二载波的速率匹配。其中，终端设备在第二载波上的速率匹配过程可参考步骤S503，本申请对此不再赘述。
结合步骤S1402b和步骤S1403b进行说明：需要说明的是，若第二时间偏移与第一时间偏移不具有第一预设关系，则网络设备向终端发送第二时间偏移。终端可以根据第二时间偏移确定第二SS Burst Set的实际发送时间，以准确地进行速率匹配。其中，终端设备在第二载波上的速率匹配过程可参考步骤S503，本申请对此不再赘述。
综上，在本实施例中，若第二时间偏移与第一时间偏移具有第一预设关系，则网络设备向终端不发送第二时间偏移，以使终端实现速率匹配，从而可以节省系统信令开销。

以实施例四或实施例五为基础，通信方法还包括：若第二SS Burst Set的SSB由多个第三天线发送，且多个第三天线在发送第一SS Burst Set的SSB时的LBT状态与多个第一天线在发送第一SS Burst Set的SSB时的LBT状态具有第二预设关系，所述LBT状态为通过LBT或者未通过LBT，则第一指示信息还用于指示多个第三天线在发送第二SS Burst Set的各SSB时分别是否通过LBT，或者，第一指示信息还用于指示第二SS Burst Set的各SSB是否被成功发送。

若第二SS Burst Set的SSB由多个第三天线发送，且多个第三天线在发送第一SS Burst Set的各SSB时的LBT状态与多个第一天线在发送第一SS Burst Set的各SSB时的LBT状态不具有第二预设关系，则网络设备向终端发送第二指示信息，第二指示信息用于指示多个第三天线在发送第二SS Burst Set的各SSB时分别是否通过LBT，或者，第二指示信息用于指示第二SS Burst Set的各SSB是否被成功发送。
其中，第一指示信息和第二指示信息可以分别在第一载波和第二载波上发送，或 者，第一指示信息和第二指示信息均在第一载波上发送，又或者，第一指示信息和第二指示信息均在第二载波上发送，本申请对此不做限制。

如图15B所示，网络设备在第一载波和第二载波上发送的第一SS burst set和第二SS burst set不同。当网络设备在发送第一SS burst set和第二SS burst set时，网络设备可以发送第一时间偏移和/或第二时间偏移，其中，第一时间偏移和第二时间偏移相同。可选地，网络设备可以发送第一指示信息和/或第二指示信息，其中，当用于发送第一SS burst set的天线的LBT状态与第二SS burst set的天线的LBT状态具有第二预设关系时，网络设备可以仅发送第一指示信息或第二指示信息。
如图15C所示，网络设备在第一载波和第二载波上发送的第一SS burst set和第二SS burst set相同，均包括SSB1、SSB2、SSB3和SSB4，但是第一SS burst set和第二SS burst set的起始发送时间具有时间间隔。因此，当网络设备在发送第一SS burst set和第二SS burst set时，网络设备可以发送第一时间偏移和/或第二时间偏移，其中，当第一时间偏移和第二时间偏移具有第一预设关系时，网络设备可以仅发送第一时间偏移或第二时间偏移。同样地，网络设备可以发送第一指示信息和/或第二指示信息，其中，第一指示信息和第二指示信息相同。
如图15D所示，网络设备在第一载波和第二载波上发送的第一SS burst set和第二SS burst set不同，而且第一SS burst set和第二SS burst set的发送时间具有时间间隔，因此当网络设备在发送第一SS burst set和第二SS burst set时，网络设备可以发送第一时间偏移和/或第二时间偏移，其中，当第一时间偏移和第二时间偏移具有第一预设关系时，网络设备可以仅发送第一时间偏移或第二时间偏移。同样地，网络设备可以发送第一指示信息和/或第二指示信息，其中，当用于发送第一SS burst set的天线的LBT状态与第二SS burst set的天线的LBT状态具有第二预设关系时，网络设备可以仅发送第一指示信息或第二指示信息。
