Abstract

本申请提供了一种通信方法和装置，该方法包括：基站获取到第一载波上承载参考信号的资源单元的时频域位置信息后，在第二载波上选择除了承载参考信号的资源单元以外的任一子帧来发送数据。本申请实施例提供的通信方法，通过基站不调度第二载波的承载参考信号的资源单元的子帧，可以使基站发送的第二载波的数据可以无干扰的被终端设备接收。

Description

一种通信方法和装置 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和装置。
背景技术
频分双工(Frequency Division Duplexing，FDD)的长期演进与5G新无线(Long Term Evolution and 5G-New Radio，LNR)共享技术是在一段频谱资源上实现长期演进(Long Term Evolution，LTE)和5G新无线(5G-New Radio，NR)两种通信制式的频谱共享技术，该技术可以实现按LTE和NR的各自需求动态分配该频资源。即，LTE小区和NR小区可在同一段频谱上进行资源共享，该段频谱既属于LTE小区也属于NR小区，可以认为是LTE标准频谱和NR标准频谱的重叠区域，可以使频谱效率最大化。但是为了避免干扰，不允许在同一个资源单元(Resource Element，RE)上既发送NR数据，又发送LTE参考信号，当然的，同一个RE上也不允许既发送LTE数据，又发送NR参考信号。因此，现有技术会采取LNR的规避协调技术：在LTE标准频谱和NR标准频谱的重叠区域中，当LTE基站发送参考信号，例如信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)时，承载LTE参考信号的RE不调度NR的数据，NR基站会将LTE CSI-RS的RE通知给NR系统的用户设备(User Equipment，UE)，以便于NR系统的UE不在这些RE上期待NR数据或解调物理下行共享信道(Physical Downlink Shared Channel，PDSCH)中的数据。
但当LTE CSI-RS图样发生变化时，需要对之前发送给用户的LTE CSI-RS RE图样进行重新配置。在对NR系统UE批量重配期间，存在模糊期问题，即：部分NR系统UE依然使用未变化前的LTE CSI-RS RE信息，部分NR系统UE会使用变化后的LTE CSI-RS RE信息。可见，在重配期间，虽然LTE系统已经生效了新的LTE CSI-RS图样，但是部分NR系统UE依然使用变化前的LTE CSI-RS RE图样进行规避，从而使得LTE系统的CSI-RS会对这些NR系统UE的数据收发产生干扰。因此，如何在LTE和NR频谱动态共享场景下，当其中任意一个系统的参考信号图样发生变化时，在批量用户重配期间，减少模糊期中存在的LTE和NR频谱冲突，是亟待解决的问题。
发明内容
有鉴于此，本申请实施例提供一种通信方法，使得基站通过避开第一载波对应的参考信号所在的子帧，对第二载波进行调度，从而减少与第一载波对应的参考信号占用的资源单元发生变化时，产生的干扰问题。

下面将结合附图详细说明本申请实施例。应理解，在下文示出的实施例中，第一、第二等仅为便于区分不同的对象，而不应对本申请构成任何限定。
同时，在本申请实施例当中，第一基站可以是5G基站，相应的，第二基站为4G基站。也可以第一基站为4G基站，第二基站为5G基站，本申请对此不做限定。
此外，在本申请实施例当中，第一载波和第二载波可以同属于一个基站，也可以属于不同基站，即适用于不同的通信场景，本申请并不限定。
为便于理解本申请实施例，下面首先对本申请中涉及的几个术语做简单介绍。
零功率资源单元(Zero-Power Resource Element，ZP-RE)或哑资源粒(Muted Resource Element，MRE)：不需要产生并映射信号的资源单元，可以用于物理下行共享信道(Physical Downlink Shared Channel，PDSCH)的速率匹配。换句话说，对于NR系统，发送LTE信号且不发送NR信号的RE位置可以设置为ZP-RE。ZP-RE可以是一块位于LTE载波和NR载波重叠区域的时频资源，在该时频资源上，NR系统的基站不发送功率或者将发送功率设置为零，NR的UE不在该位置上接收信号或者将接收功率设置为零。但是，LTE系统的基站和UE可以通过该特定的时频资源进行通信。ZP-RE对于NR来说也可以称为空RE。
参考信号图样：参考信号所在的RE在时频域上的二维分布。
重配模糊期：在批量重配用户期间，UE和基站、LTE侧和NR侧对于需要规避的RE理解不一致的时间段。
图1示出了本申请实施例的无线通信系统100的示意图。
如图所示，该通信系统100可以包括两个网络设备，例如图1中所示的网络设备101和102。该通信系统100还可以包括两个终端设备，例如图1中所示的终端设备103和104，其中终端设备103可以通过双连接(dual connectivity，DC)技术或者多连接技术与5G网络设备101建立无线链路，终端设备104可以通过双连接(dual connectivity，DC)技术或者多连接技术与4G网络设备102建立无线链路。
应理解，在本申请实施例中，终端设备与网络设备之间、终端设备与终端设备之间可以建立无线连接，进行无线通信，发送设备可以通过控制信息指示数据的调度信息，以便接收设备根据控制信息正确地接收数据。其中，网络设备101也可以为主基站，网络设备102例如可以为辅基站，在此情况下，网络设备101为终端设备103初始接入时的网络设备，负责与终端设备103之间的无线资源控制(radio resource control，RRC)通信，网络设备102可以是RRC重配置时添加的，用于提供额外的无线资源。或者网络设备101也可以为4G网络设备，网络设备102可以为5G网络设备，本申请不做限定。此外，在本申请实施例中，4G与5G网络设备也可以是同一个，在这种情况下该网络设备可以发送或接收LTE载波，同时也可以发送或接收NR载波，本申请不做限定。
应理解，在图1中，终端设备103与网络设备101连接，即该终端设备与网络设备之间通过NR标准频谱工作，终端设备104与网络设备102连接，即该终端设备与网络设备之间通过LTE标准频谱工作。此外，在本申请实施例中，终端设备也可以是同一个终端设备，即该终端设备可以支持LTE和NR两种制式，本申请对此不做任何限定。
此外，在本申请中，该通信系统100可以包括至少一个网络设备，NR侧和NR小区/载波可以属于同一个基站，同时，LTE侧和LTE小区/载波、NR侧和NR小区/载波可以理解为一个概念，LTE侧和LTE小区/载波、也可以分别属于不同的基站，当本申请用于一个基站的场景时，该基站既可以在NR标准频谱下发送载波，也可以在LTE标准频谱下发送载波。因此，本申请中的第一载波和第二载波并不限定是由两个基站或者一个基站发送，即本申请对此不做任何限定。
为了方便阐述，下面将以LTE和NR系统中的帧结构为例，首先介绍一下空口通信中的物理帧。
物理帧一般是指数据链路层的协议数据单元。物理帧由几个执行不同功能的部分组成，帧结构是指能够按照传送信息的不同，组成不同的重复周期的帧。为了满足时分复用中的上下行时间转换的要求，TD-LTE设计了专门的无线帧结构。在TD-LTE时域中，以周期方式同时传输、且标准配置上下行子帧数的帧结构有无线帧和半帧2种，无线帧时长10ms，半帧时长5ms，1个无线帧由2个半帧组成。每个半帧由时长1ms的5个子帧组成，每个子帧由时长0.5ms的2个时隙组成，每个时隙可以根据循环前缀CP的不同时长，分别由6个或7个CP+OFDM符号组成。
与4G固定帧结构相比，5G帧结构的最大特点是灵活多变。5G帧采用的是分层结构方式，由固定架构和灵活架构2部分组成。其中固定架构与4G一样，由时长为10ms的无线帧和时长为1ms的子帧组成。每个帧分2个半帧，第一个半帧包含子帧0～4，第二个半帧包含子帧5～9。每个子帧由若干个时隙组成。
在LTE系统或者NR系统中，系统帧序号(system frame number，SFN)的范围可以为0～1023，即基本的数据发送周期为1024个帧。而子帧号的范围为0～9，即部分控制信息的发送周期为10个子帧。
本申请实施例中，第一载波可以是LTE载波，第二载波可以是NR载波。或者，第一载波可以是NR载波，第二载波可以是LTE载波。
本申请实施例中，基站调度某一子帧可以指的是基站会在该子帧内调度上行或者下行数据。基站不调度或者停止调度某一子帧可以指的是基站不会在该子帧内调度上行或者下行数据，但仍然有可能发送参考信号等。
图2是本申请实施例提供的一种通信方法200的示意性流程图。
S210，基站获取第一载波上承载参考信号的资源单元的时频域位置信息。
具体地，当LTE小区与NR小区共基站时，即该基站既可以通过LTE载波也可以通过NR载波与终端进行通信。该第一载波上承载的参考信号可以由该基站产生并服务于一个或者多个终端设备。此时该基站可以自行确定第一载波上承载参考信号的资源单元的时频域位置信息。
S220，该基站在第二载波的第一子帧上向终端发送数据，其中，该第一子帧为除了承载所述参考信号的资源单元所在的子帧之外的任一子帧。
具体而言，当基站向终端设备发送第二载波时，基站通过获取的第一载波上承载参考信号的资源单元的时频域位置信息，将承载所述参考信号的资源单元所在的子帧停止调度，在其他子帧上发送数据。
例如，基站确定第一载波上承载参考信号的资源单元所在的子帧为子帧n，当基站在第二载波上发送数据时，基站会避开子帧n，在其他子帧上发送承载在第二载波上的数据。
应理解，基站获取第一载波上承载参考信号的资源单元的时频域位置信息也可以是通过其他基站发送的第一消息来获取的，例如图3所述的通信方法300的示意性流程图。
S310，第二基站向终端设备发送承载在第一载波上的参考信号。
S320，第二基站向第一基站发送第一消息，该第一消息包括该第二基站向终端设备发送的该第一载波上承载参考信号的资源单元的时频域位置信息。
具体地，当LTE小区与NR小区为非共站时，即存在LTE基站和NR基站共同部署的场景，此时，第一基站可以是LTE基站，也可以是NR基站，反之亦可，本申请对此并不限定。
需要说明的是，S310与S320这两个步骤并没有严格的先后顺序，不可按照数字的大小表示动作的先后，换句话说，第二基站也可以先向第一基站发送第一载波上承载参考信号的资源单元的时频域位置信息后再向终端设备发送第一载波上承载的参考信号。
当第一基站接收到第二基站发送的第一消息后，第一基站执行例如图2所示的方法200的步骤220，即该第一基站向终端设备发送承载在第二载波的第一子帧上的数据，其中，该第一子帧为除了承载所述参考信号的资源单元所在的子帧之外的任一子帧。
换句话说，该第一基站在向终端设备发送数据时，会停止调度第一载波上承载参考信号的资源单元的所在的子帧。该第一基站可以在其他任一子帧上发送数据。
例如，基站确定第一载波上承载参考信号的资源单元所在的子帧为子帧n，当基站在第二载波上发送数据时，基站会避开子帧n。该第一基站可以在其他任一子帧上发送承载在第二载波上的数据。
应注意，在本申请实施例中，第一消息可以是跨制式通信消息或者用于第一基站和第二基站进行通信的其他消息，本申请对此不做任何限定。
因此，通过本申请实施例提供的通信方法，由于基站停止调度第二载波上承载参考信号的资源单元子帧，可以使基站在发送第二载波时，针对参考信号所在的RE进行无干扰的避让，减少了在频谱共享中存在的LTE和NR频谱冲突问题。
图4是本申请实施例提供的另一种通信方法400的示意性流程图。
在本实施例中，以非共站为例介绍该方法。
S410，第二基站通过第一消息将第一载波上承载参考信号的资源单元的时频域位置信息发送给第一基站。
该第一消息中包括所述第一载波上承载参考信号的资源单元的时频域位置信息。
S420，第一基站向终端设备发送承载在第二载波的第一子帧的数据。
具体地，第一基站通过第一消息获取到第一载波上承载参考信号的资源单元的时频域位置信息，在除了承载该参考信号的资源单元的子帧以外的子帧，即第一子帧上向终端设备发送承载在第二载波上的数据。
S430，第一基站根据收到的参考信号的资源单元的时频位置信息将第二载波上对应的资源单元设置为零功率资源单元。
S440，第一基站通过第二消息将零功率资源单元位置信息发送给终端设备。
S450，终端设备向第一基站发送第三消息，该第三消息指示终端设备已经完成了零功率资源单元的配置。
S460，该第一基站在第二载波的第一资源单元上向所述终端设备发送数据。其中，该第一资源单元为承载参考信号的资源单元所在的子帧中，除了承载参考信号的资源单元之外的任一资源单元。
具体来说，当第一基站确定终端设备完成了零功率资源单元的配置后，第一基站在向终端设备发送数据时，可以不再停止调度第一载波上承载参考信号的资源单元的子帧，而是通过零功率资源单元来减少参考信号与数据的干扰。
应理解，本申请实施例可以用在第一基站初始建立的过程中，当第一基站处于初始建立的过程中时，第一基站第一次收到来自第二基站发送的参考信号的资源单元的时频位置信息，换句换说，本申请实施例可以用在第一基站首次接收到来自第二基站的第一消息的情况下，第一基站采用停止调度承载该参考信号的资源单元的子帧来减少信号干扰。
可选的，本申请实施例也可以用在终端设备批量重配置过程中，终端设备批量重配置的过程发生在第二基站的参考信号的资源单元的时频位置发生变化后，为了减少干扰，第一基站需要先确定第二基站的参考信号的资源单元的时频位置发生了变化，随后根据该变化后的参考信号的资源单元的时频位置，重新设置零功率资源单元。因此，第一消息可以包括变化后的第二基站的参考信号的资源单元的时频位置信息。
换句话说，本申请实施例的方法，可以应用于基站初始配置零功率资源单元时，也可以应用于重配置零功率资源单元时，本申请对此不做限定。
需要说明的是，当本申请实施例中的第一载波和第二载波具有重叠区域时，本申请实施例的方法可以是在重叠区域内实施的，此时，在第一载波和第二载波的重叠区域中，第一载波上承载参考信号的资源单元的时频域位置和第二载波对应的资源单元设置其实是同一个时频位置。
应理解，在本实施例当中，若终端设备完成了该零功率资源单元的配置，也可以不向第一基站发送第三消息。
可选的，在本申请实施例中，参考信号可以是信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)。或者该参考信号可以是存在于LTE系统或者NR系统中的其他参考信号，例如可以是并存于LTE系统和NR系统中的其他参考信号本申请对此不作任何限定。
此外，在本申请实施例中，第一基站发送给终端设备的第二消息，本申请也不做任何限定，可以是高层信令，例如，可以是无线资源控制信令(Radio Resource Control，RRC)或其他信令。
本申请实施例提供的通信方法，使得在批量重配用户期间，第一基站通过停止调度承载第一载波上的参考信号的资源单元的子帧，从而减少当参考信号占用的资源单元发生变化时产生的第一基站与第二基站的频谱冲突问题。
以上，结合图2至图4详细说明了本申请实施例提供的方法。以下，结合图5和图6详细说明本申请实施例提供的通信装置。
图5是本申请实施例提供的一种通信装置的示意性框图。如图5所示，该装置500可以包括处理单元510和收发单元520。
处理单元510用于获取第一载波上承载参考信号的资源单元的时频域位置信息。
收发单元520用于在第二载波的第一子帧上向终端发送数据，其中，该第一子帧为除了承载参考信号的资源单元所在的子帧之外的子帧。可选的，该收发单元520还可以用于接收第二基站发送的第一消息，该第一消息包括该第二基站的第一载波上承载参考信号的资源单元的时频域位置信息，此时，该装置的处理单元510具体用于根据该第一消息获取第一载波上承载参考信号的资源单元的时频域位置信息。
可选的，该处理单元510确定第一载波上承载参考信号的资源单元的时频域位置信息有变更时，该处理单元停止调度承载该参考信号的资源单元所在的子帧。
可选的，本实施例所述的装置的处理单元510还用于根据第一载波上承载参考信号的资源单元的时频域位置信息将第二载波上对应的资源单元设置为零功率资源单元。此时，收发单元520还用于向终端设备发送第二消息，该第二消息包括零功率资源单元的时频域位置信息，并指示终端设备在零功率资源单元上不接收第二载波的数据。
同样的，该收发单元发送给终端设备的第二消息，本申请也不做任何限定，可以是高层信令，例如，可以是无线资源控制信令(Radio Resource Control，RRC)或其他信令。
此外，该装置的收发单元520还用于接收该终端设备发送的第三消息，该第三消息表示该终端设备已经完成零功率资源单元的配置。
可选的，该第三消息可以是终端设备发送的响应消息。
可选的，收发单元520中接收的参考信号或处理单元处理的参考信号包括信道状态信息参考信号CSI-RS。
