Description

数据传输方法、设备及装置 技术领域
本公开涉及通信技术领域，特别涉及一种数据传输方法、设备及装置。
背景技术
5G(5th-Generation，第五代移动通信技术)NR(New Radio，新无线电通信)作为5G领域的一个重要的应用场景，可采用非授权频段传输数据。其中，非授权频段是指无需授权即可***的频段，常见的WiFi即运行在非授权频段中。由于非授权频段不受运营商部署网络的管制，邻近基站间在传输数据时会彼此干扰。为避免邻近基站的干扰，基站在使用非授权频段所划分的某个信道传输数据之前，可采用LBT(License Before Talk，先听后说)机制对该信道进行监听，如果监听到其他基站未占用该信道，则采用该信道传输数据。
采用非授权频段中的信道进行数据传输时，依据传输机制不同，基站的类型可分为两种，一类是LBE(Load Based Equipment，基于负载的设备)基站，另一类为FBE(Frame Based Equipment，FBE)基站。LBE基站基于负载需要进行动态调度，其占用信道的时间和长度是动态的，虽然资源调度更灵活，但调度机制十分复杂，不利于应用；FBE基站在固定的周期内进行调度，虽然调度方式不够灵活，但更易控制，目前已在通信领域得到广泛应用。
考虑到不同FBE基站的业务不同，每个FBE基站需要配置不同的FFP(Fixed Frame Period，固定帧周期)，当相邻FBE基站基于LBT机制进行数据传输时，不同的FFP可能会互相影响。例如，一个FBE基站在配置了FFP后，另一个FBE基站再配置FFP时如果与之冲突，则进行LBT时会监听失败，从而影响数据传输，因此，为了提高FBE基站传输数据的成功率，亟需一种新的数据传输方法。

图3是根据一示例性实施例示出的一种数据传输方法的流程图，如图3所示，数据传输方法应用于数据传输设备中，该数据传输设备包括第二基站或第二基站中的终端。数据传输方法包括以下步骤。
在步骤S301中，数据传输设备预先与第一基站进行时间同步。
其中，数据传输设备包括第二基站或第二基站中的终端，第二基站为第一基站相邻且存在干扰的基站。在进行数据传输之前，数据传输设备需要与第一基站进行时间同步。该时间同步是指相邻两个基站间实现同步对齐，或者两个基站通过同步过程获取相互之间的FFP的时间差。
进一步地，为了更好地确定出第一基站的FFP传输模式，第二基站还可基于获取到的与第一基站的FFP之间的时间差，对第一基站的各个FFP进行编号，从而对第一基站在FFP内的数据传输过程进行监听时，能够获知进行数据传输的当前FFP的相对位置及其编号。例如，图4、图5、图6中将三个相邻的FFP依次编号为FFP0、FFP1、FFP2。
在步骤S302中，第一基站在至少一个FFP预设的LBT时频区域内进行数据传输。
基于预先设置的FFP，每当达到FFP时，第一基站在FFP预设的LBT时频区域内，按照预设的时频模式传输数据。本公开实施例中所述的按照预设的时频模式传输数据是指第一基站在不同时间和不同频段子区域内传输数据。
其中，第一基站传输的数据可以为有效数据，也可以为任意无效的干扰数据，本公开实施例不对第一基站所传输的数据作具体的限定。预设的LBT时频区域为第一基站在FFP内的空闲区域，预设的LBT时频区域可以包括至少一个频段，该至少一个频段包括CC频段、BWP频段或RB等。该预设的LBT时频区域通常会被划分为至少一个子时频区域，该至少一个子时频区域用于数据传输设备对第一基站的数据传输情况进行监听。
在步骤S303中，数据传输设备对第一基站在至少一个FFP预设的LBT时频区域内的数据传输情况进行监听。
当需要进行数据传输时，数据传输设备可基于LBT机制，对第一基站在至少一个FFP预设的LBT时频区域内的数据传输情况进行监听。该过程中，对于所监听的FFP数量，可由第二基站进行设置。通过对第一基站至少一个FFP预设的LBT时频区域内的数据传输情况进行监听，数据传输设备可确定出第一基站的FFP传输模式，从而基于第一基站的FFP传输模式进行干扰规避。参见图4、图5、图6，数据传输设备对第一基站在FFP0、FFP1、FFP2三个预设的LBT时频区域内的数据情况进行监听。
在步骤S304中，数据传输设备根据对每个FFP预设的LBT时频区域中每个子时频区域的监听结果，确定第一基站的FFP传输模式信息。
其中，FFP传输模式信息与至少一个FFP预设的LBT时频区域中各个子时频区域的占用状态的组合对应。占用状态是指能够监听到第一基站进行数据传输的状态，也即是，如果在任一FFP预设的LBT时频区域中任一子时频区域上监听到第一基站进行数据传输，则确定该子时频区域处于占用状态。
具体地，数据传输设备根据对每个FFP预设的LBT时频区域中每个子时频区域的监听结果，确定第一基站的FFP传输模式信息时，可采用如下步骤：3041、数据传输设备根据对每个FFP预设的LBT时频区域中每个子时频区域的监听结果，按照预设规则，确定至少一个FFP预设的LBT时频区域中各个子时频区域的占用状态的组合。
其中，预设规则用于指示至少一个FFP预设的LBT时频区域中各个子时频区域的监听结果与至少一个FFP预设的LBT时频区域中各个子时频区域的占用状态的组合之间的对应关系。该预设规则可由第二基站预先进行设置。
在本公开的一个实施例中，该预设规则可以为当在任一FFP预设的LBT时频区域中指定位置的子时频区域上监听到第一基站进行数据传输，则对至少一个FFP预设的LBT时频区域中指定位置的子时频区域的占用状态进行组合时，可确定组合后的该指定位置的子时频区域处于占用状态。例如，图4中的左图，当在FFP0、FFP1、FFP2预设的LBT时频区域内任一个左侧子时频区域上监听到第一基站的数据传输操作，则对FFP0、FFP1、FFP2预设的LBT时频区域中左侧时频区域的占用状态进行组合时，可确定组合后的左侧时频区域处于占用状态。
在本公开的另一个实施例中，该预设规则还可以为当在至少两个FFP预设的LBT时频区域中指定位置的子时频区域上监听到第一基站进行数据传输，则对至少一个FFP预设的LBT时频区域中指定位置的子时频区域的占用状态进行组合时，可确定组合后的该指定位置的子时频区域处于占用状态。图4中的左图，当在FFP0、FFP1、FFP2中至少两个FFP预设的LBT时频区域内左侧子时频区域上监听到第一基站的数据传输操作，则对FFP0、FFP1、FFP2预设的LBT时频区域中左侧时频区域的占用状态进行组合时，可确定组合后的左侧时频区域处于占用状态。
在本公开的另一个实施例中，该预设规则还可以为当在所有FFP预设的LBT时频区域中指定位置的子时频区域上均监听到第一基站进行数据传输，则对至少一个FFP预设的LBT时频区域中指定位置的子时频区域的占用状态进 行组合时，可确定组合后的该指定位置的子时频区域处于占用状态。图4中的左图，当在FFP0、FFP1、FFP2预设的LBT时频区域内左侧子时频区域上均监听到第一基站的数据传输操作，则对FFP0、FFP1、FFP2预设的LBT时频区域中左侧时频区域的占用状态进行组合时，可确定组合后的左侧时频区域处于占用状态。
当然，预设规则还可以包括其他内容，此处不再一一说明。
当设置了预设规则之后，第二基站还可通过广播信令、物理层控制信令、上层RRC(Radio Resource Control，无线资源控制)信令或MAC(Media Access Control，媒体访问控制)CE(Control Element，控制元素)信令将预设规则传输至第二基站中的每个终端，从而使得每个终端在对第一基站在FFP预设的LBT时频区域内的数据传输过程进行监听时，能够确定出第一基站的FFP传输模式信息。
基于预先设置的预设规则，数据传输设备根据对每个FFP预设的LBT时频区域中每个子时频区域的监听结果，即可确定出至少一个FFP预设的LBT时频区域中各个子时频区域的占用状态的组合。例如，参见图4，设定预设规则为当在任一FFP预设的LBT时频区域中指定位置的子时频区域上监听到第一基站进行数据传输，则对至少一个FFP预设的LBT时频区域中指定位置的子时频区域的占用状态进行组合时，可确定组合后的该指定位置的子时频区域处于占用状态。基于所设置的预设规则，对于图4中的左图，数据传输设备对第一基站在FFP0、FFP1、FFP2预设的LBT时频区域内的数据传输情况进行监听，当在FFP0、FFP1、FFP2中任一个FFP预设的LBT时频区域中右侧子时频区域上监听到数据传输操作，则数据传输设备对FFP0、FFP1、FFP2预设的LBT时频区域中右侧子时频区域的占用状态进行组合时，可确定组合后的右侧子时频区域处于占用状态；对于图4中的右图，数据传输设备对第一基站在FFP0、FFP1、FFP2预设的LBT时频区域内的数据传输情况进行监听，当在FFP0、FFP1、FFP2中任一个FFP预设的LBT时频区域中中间子时频区域上监听到数据传输操作，则数据传输设备对FFP0、FFP1、FFP2预设的LBT时频区域中中间子时频区域的占用状态进行组合时，可确定组合后的中间子时频区域处于占用状态。
3042、数据传输设备根据至少一个FFP预设的LBT时频区域中各个子时频区域的占用状态的组合，确定第一基站的FFP传输模式信息。
在本公开的一个实施例中，FFP传输模式信息包括一维FFP传输模式信息、二维FFP传输模式信息或二维扩展FFP传输模式信息等。其中，一维FFP传输模式信息用于表征第一基站在同一频段上、至少一个FFP预设的LBT时频区域中相对位置相同的子时频区域的占用状态的组合。参见图4，图4中左图的FFP传输模式信息表征了基站A在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧子时频区域的占用状态的组合；图4中右图的FFP传输模式信息表征了基站A在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中中间子时频区域的占用状态的组合。
二维FFP传输模式信息可以是基于一维FFP传输模式信息在频域上所做的扩展，此时该二维FFP传输模式信息用于表征第一基站在至少两个频段上、至少一个FFP预设的LBT时频区域中相对位置相同的子时频区域的占用状态的组合。参见图5，图5中左图的FFP传输模式信息表征了第一基站在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧子时频区域的占用状态的组合，及在SWP2频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中中间子时频区域的占用状态的组合，以及在SWP3频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧子时频区域的占用状态的组合；图5中右图的FFP传输模式信息表征了第一基站在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中中间子时频区域的占用状态的组合，及在SWP2频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右子时频区域的占用状态的组合，以及在SWP3频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中中间子时频区域的占用状态的组合。二维FFP传输模式信息还可以是基于一维FFP传输模式信息在时间域上所做的扩展，此时该二维FFP传输模式信息用于表征第一基站在同一频段上、至少一个FFP预设的LBT时频区域中相对位置不同的子时频区域的占用状态的组合。由于二维FFP传输模式信息需要数据传输设备在不同频率上均进行监听，因此，监听复杂度程度较高。
二维扩展FFP传输模式信息是基于一维FFP传输模式信息在时间域和频域上所做的扩展，该二维扩展FFP传输模式信息用于表征第一基站在至少两个频段上、至少一个FFP预设的LBT时频区域中相对位置不同的子时频区域的占用状态的组合。参见图6，图6中左图的FFP传输模式信息表征了第一基站在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧 子时频区域的占用状态的组合，及在SWP2频段上、FFP0预设的LBT时频区域中左侧子时频区域、FFP1预设的LBT时频区域中右侧子时频区域、FFP2预设的LBT时频区域中左侧子时频区域的占用状态的组合，以及在SWP3频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧子时频区域的占用状态的组合；图6中右图的FFP传输模式信息表征了第一基站在SWP1频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中左侧子时频区域的占用状态的组合，及在SWP2频段上、FFP0、FFP1、FFP2三个FFP预设的LBT时频区域中右侧子时频区域的占用状态的组合，以及在SWP3频段上、FFP0预设的LBT时频区域中中间子时频区域、FFP1预设的LBT时频区域中右侧子时频区域、FFP2预设的LBT时频区域中中间子时频区域的占用状态的组合。由于二维扩展FFP传输模式信息需要数据传输设备在不同时间域和频率上均进行监听，因此，监听复杂度程度最高。
在步骤S305中，数据传输设备根据FFP传输模式信息，确定第一基站的FFP传输模式。
在本公开实施例中，每种FFP传输模式信息与第一基站的一种FFP传输模式对应，因此，基于FFP传输模式信息，数据传输设备可确定出第一基站的FFP传输模式。具体地，数据传输设备可根据FFP传输模式信息，按照预设映射关系进行映射，得到第一基站的FFP传输模式。其中，预设映射关系可由第二基站进行设置，该预设映射关系中规定了组合后的每个子时频区域所代表的FFP占用情况，实际上，该预设映射关系指示了FFP传输模式信息与FFP传输模式之间的对应关系。参见图4，预设映射关系指示组合后的左侧子时频区域代表FFP全部不占用，中间子时频区域代表FFP占用三分之一，右侧子区域代表FFP全部被占用，基于所设置的预设映射关系，数据传输设备对图4中左图所示的FFP传输模式信息进行映射，得到三个FFP被占用的FFP传输模式；数据传输设备对图4中右图所示的FFP传输模式信息进行映射，得到中间FFP被占用的FFP传输模式。
进一步地，当设置了预设映射关系后，第二基站还可将预设映射关系通过广播信令、物理层控制信令、上层RRC信令或MAC CE信令传输至第二基站中的每个终端。
在本公开的另一个实施例中，当数据传输设备为第二基站时，数据传输设备根据FFP传输模式信息，确定第一基站的FFP传输模式之后，还可根据第 一基站的FFP传输模式，确定出第二基站的FFP传输模式。基于第一基站的FFP传输模式所确定的第二基站的FFP传输模式，可规避第一基站的干扰，提高数据传输的成功率。
在本公开的一个实施例中，当数据传输设备为第二基站中的终端时，数据传输设备还可将FFP传输模式信息发送至第二基站，当接收到FFP传输模式信息时，第二基站根据预设映射关系，确定出第一基站的FFP传输模式，进而根据第一基站的FFP传输模式，调整第二基站的FFP传输模式，从而规避所有第一基站已经进行数据传输的时频位置，以提高传输数据的成功率。
在本公开的一个实施例中，当数据传输设备为第二基站中的终端时，数据传输设备还可将第一基站的FFP传输模式发送至第二基站，使得第二基站能够根据第一基站的FFP传输模式，调整第二基站的FFP传输模式，从而可规避所有第一基站已经进行数据传输的时频位置，以提高传输数据的成功率。
在本公开的另一个实施例中，当数据传输设备为第二基站中的终端时，数据传输设备根据FFP传输模式信息，确定第一基站的FFP传输模式之后，还可根据第一基站的FFP传输模式，调整向第二基站所发送的数据传输请求，从而可规避第一基站的干扰，以提高数据传输的成功率。
在本公开的另一个实施例中，第一基站在FFP内进行数据传输时，所传输的数据包括上行数据、下行数据及上下行数据，根据所传输数据的数据类型，第一基站的FFP传输模式可以包括FFP上行传输模式、FFP下行传输模式及FFP上下行传输模式。其中，FFP上行传输模式是指对第一基站在FFP预设的LBT时频区域内传输的上行数据进行监听得到的模式；FFP下行传输模式是指对第一基站在FFP预设的LBT时频区域内传输的下行数据进行监听得到的模式；FFP上下行传输模式是指对第一基站在FFP预设的LBT时频区域内传输的上下行数据进行监听得到的模式。第二基站通过将第一基站的FFP传输模式进行分类，可确定出第一基站的干扰类型，从而基于干扰类型进行进一步调度判断。例如，如果第一基站的FFP传输模式为FFP上行传输模式，则第二基站可以选择规避第一基站上行数据传输的FFP；如果第一基站的FFP传输模式为FFP下行传输模式，则第二基站可以选择规避第一基站下行数据传输的FFP；如果第一基站的FFP传输模式为FFP上下行传输模式，则第二基站可以选择规避第一基站上下行数据传输的FFP。
本公开实施例提供的方法，通过对第一基站在至少一个FFP预设的LBT 时频区域内的数据传输情况进行监听，确定第一基站的FFP传输模式信息，进而根据FFP传输模式信息，确定出第一基站的FFP传输模式。该方法无需经过基站间信令交互，即可获取邻近的其他基站的FFP传输模式，从而能够进行干扰规避的传输调度。
