Description

FBE的数据传输方法、装置及存储介质 技术领域
本公开涉及通信技术领域，特别涉及一种FBE(Frame Based Equipment，基于帧的设备)机制下的数据传输方法、装置及存储介质。
背景技术
对于非授权频段的使用，为了实现与WiFi(Wireless Fidelity，无线保真)及其他运营商LAA(Licensed-Assisted Access，授权频谱辅助接入)网络的和谐共存，减少相互之间的干扰，引入非授权频段LBT(Listen before Talk，先听后说)。LBT定义了两类设备，一类是FBE，另一类是LBE(Load Based Equipment，基于负载的设备)。对于FBE，设定一个周期，每个周期的固定位置进行一次信道检测，如在每个CCA(Clear Channel Assessment，空闲信道评估)检测时间内进行CCA检测。若检测到信道状态为空闲，即可占用信道进行传输；若检测到信道状态为非空闲，则在这个周期内设备不能占用信道，直至等到下一个周期的固定位置继续检测。
如果在每个周期内执行CCA进行干扰检测，会给设备带来较大的处理开销，且接入信道的成功率也无法保障。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的一种网络架构的示意图。该网络架构可以包括：多个接入网设备110和终端120。各个接入网设备110部署在RAN(Radio Access Network，无线接入网)10中。
终端120的数量通常为多个，每一个接入网设备110所管理的小区内可以分布一个或多个终端120。
接入网设备110与终端120之间通过某种空口技术互相通信，例如可以通 过蜂窝技术相互通信。本公开实施例描述的技术方案可以适用于LTE系统，也可以适用于LTE系统后续的演进系统，如LTE-A(LTE-Advanced)系统、5G系统(也称为NR(New Radio)系统)等。
本公开实施例中，名词“网络”和“系统”经常交替使用，但本领域技术人员可以理解其含义。
本公开实施例所涉及到的终端可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile Station，MS)，终端设备(terminal device)等等。为方便描述，上面提到的设备统称为终端。
本公开实施例所涉及到的RAN中的接入网设备可以是基站(Base Station，BS)，所述基站是一种部署在RAN中用以为终端提供无线通信功能的装置。所述基站可以包括各种形式的宏基站，微基站，中继站，接入点等等。在采用不同的无线接入技术的系统中，具备基站功能的设备的名称可能会有所不同，例如在LTE系统中，称为演进的节点B(evolved NodeB，eNB或eNodeB)，在3G通信系统中，称为节点B(Node B)等等。随着通信技术的演进，“基站”这一名称可能会变化。为方便描述，本公开实施例中，上述为终端提供无线通信功能的装置统称为接入网设备。
为了提升无线信号的传输质量，引入波束成形(beamforming)技术，实现定向信号发送或接收。结合参考图2，图2是根据一示例性实施例示出的一种应用场景的示意图。该应用场景可以包括：第一接入网设备21、第二接入网设备22、第一终端23和第二终端24。其中，第一终端23位于第一接入网设备21服务的小区内，第二终端24位于第二接入网设备22服务的小区内。
如图2所示，第一接入网设备21可以包括多个天线，该多个天线能够产生多个不同指向的波束(beam)，覆盖第一接入网设备21所服务的小区。第一接入网设备21可以通过波束向小区内的终端定向发送信号，也可以通过波束定向接收小区内的终端发送的信号。
类似地，第二接入网设备22也可以包括多个天线，该多个天线能够产生多个不同指向的波束，覆盖第二接入网设备22所服务的小区。第二接入网设备22可以通过波束向小区内的终端定向发送信号，也可以通过波束定向接收小区内的终端发送的信号。
如图2所示，当第一接入网设备21和第二接入网设备22邻近部署时，两个设备指向相同或接近的波束间，会存在较大的传输干扰。如图2所示，假设第一接入网设备21正在使用波束5和6向第一终端23发送下行数据，第二接入网设备22正在使用波束10和11向第二终端24发送下行数据，由于波束5和6与波束10和11的指向接近，因此第一终端23的接收会受到第二接入网设备22与第二终端24间的下行传输的干扰，第二终端24的接收也会受到第一接入网设备21与第一终端23间的下行传输的干扰。
另外，假设第一接入网设备21正在使用波束5和6接收第一终端23发送的上行数据，第二入网设备22正在使用波束10和11向第二终端24发送下行数据，第二终端24的接收也会受到第一终端23与第一接入网设备21间的上行传输的干扰。
对于LBE来说，如果设备(终端或接入网设备)在每个周期内执行CCA进行干扰检测，会给设备带来较大的处理开销，且接入信道的成功率也无法保障。
在本公开实施例提供的技术方案中，通过接入网设备获取其邻近接入网设备的波束占用信息和周期占用信息，当存在使用具有干扰互斥关系的波束传输数据的需求时，根据邻近接入网设备传输数据所占用的固定周期，确定当前需要传输的数据占用的固定周期，从而有针对性地选择无传输干扰的固定周期来传输数据。相较于通过CCA在每个周期重复地进行干扰检测，采用本公开实施例提供的技术方案，可以在周期选择上就规避干扰，减少CCA所带来的处理开销，提升接入信道的成功率。
图3是根据一示例性实施例示出的一种FBE的数据传输方法的流程图。该方法可应用于图2所示的应用场景中。该方法可以包括如下几个步骤。
在步骤301中，第二接入网设备接收第一接入网设备发送的传输状态指示信息。
传输状态指示信息用于指示第一接入网设备与第一终端之间传输第一数据时的相关传输状态，可以包括波束占用信息和周期占用信息。上述第一数据可以包括第一接入网设备向第一终端发送的下行数据和/或第一终端向第一接入网设备发送的上行数据。
波束占用信息用于指示第一接入网设备与第一终端之间传输第一数据所 占用的第一波束。其中，第一波束的数量可以是1个，也可以是多个。波束占用信息可以包括第一波束的标识信息。波束的标识信息用于唯一指示该波束，不同的波束对应不同的标识信息。可选地，波束的标识信息包括该波束对应的SSB(synchronization signal and PBCH Block，同步信号和物理广播信道块)索引，也即SSB index。例如，结合参考图2，假设第一接入网设备21通过波束5向第一终端23发送下行数据，则第一接入网设备21向第二接入网设备22发送的波束占用信息可以包括波束5的标识信息。
周期占用信息用于指示传输第一数据所占用的固定周期。固定周期是指FBE调度的时域单元，例如固定周期可以是FFP(Fixed Frame Period，固定帧周期)。固定周期的时长可以由协议预先规定。第一接入网设备通过向第二接入网设备发送周期占用信息，以告知第二接入网设备传输第一数据占用了哪个或哪些固定周期。示例性地，周期占用信息可以采用bit map来表示，例如，1表示固定周期被占用，0表示固定周期空闲(也即未被占用)。结合参考图4，第一接入网设备与第一终端传输第一数据所占用的固定周期可以表示为110101，即第一个固定周期、第二个固定周期、第四个固定周期和第六个固定周期被传输第一数据所占用，第三个固定周期和第五个固定周期未被其占用。
可选地，周期占用信息可以包括周期指示信息和周期相关信息；其中，周期指示信息用于指示传输第一数据所占用的固定周期，周期相关信息用于指示固定周期的相关参数，可以包括固定周期的时长、固定周期的数量、固定周期中COT(Channel Occupancy Time，信道占用时长)等信息。
可选地，传输状态指示信息还包括FBE指示信息，用于指示第一接入网设备在传输第一数据时的调度机制为FBE调度机制。当第一接入网设备在传输第一数据时的调度机制为FBE调度机制，第二接入网设备在传输第二数据时的调度机制也为FBE调度机制时，第二接入网设备执行接下来的步骤流程。当第一接入网设备在传输第一数据时的调度机制不是FBE，和/或，第二接入网设备在传输第二数据时的调度机制不是FBE时，第二接入网设备不执行接下来的步骤流程，其可以执行其他相应机制下的数据传输流程。
可选地，传输状态指示信息还包括频域指示信息；其中，频域指示信息用于指示传输第一数据所占用的频域资源。频域资源可以包括CC(Component Carrier，载波单元)、BWP(Bandwidth Part，一部分带宽)等频域单元的标识信息。
可选地，传输状态指示信息还包括：传输类型指示信息，传输类型指示信息用于指示第一数据对应的传输类型，传输类型包括上行传输和下行传输。上行传输是指终端向接入网设备发送数据，也即接入网设备从终端接收数据；下行传输是指接入网设备向终端发送数据，也即终端从接入网设备接收数据。
第二接入网设备可以通过空中接口接收第一接入网设备发送的传输状态指示信息，其中，上述空中接口可以是X2接口，也可以是与X2接口等效的空中接口。
在步骤302中，第二接入网设备确定与第一波束具有干扰互斥关系的第二波束。
可选地，第二接入网设备可以根据预存的干扰互斥信息，确定与第一波束具有干扰互斥关系的第二波束；其中，干扰互斥信息包括至少一组波束间的干扰互斥关系。可选地，第二接入网设备中预存的与第一接入网设备对应的干扰互斥信息，包括至少一组第一接入网设备的波束和第二接入网设备的波束之间的干扰互斥关系。在一个示例中，干扰互斥信息可以包括第二接入网设备与第一接入网设备间干扰最大的一组波束间的干扰互斥关系。在另一个示例中，干扰互斥信息可以包括第二接入网设备与第一接入网设备的波束间存在的所有干扰互斥关系。
上述干扰互斥关系可以在接入网设备部署时预设，也可以在接入网设备部署时，经初始化测量得到。
可选地，初始化测量过程如下：当第一接入网设备采用第一目标波束发送测量信号时，第二接入网设备采用第二目标波束接收测量信号，并获取该测量信号的接收信号强度；当测量信号的接收信号强度大于预设阈值时，第二接入网设备确定第二目标波束与第一目标波束具有干扰互斥关系；当测量信号的接收信号强度小于预设阈值时，第二接入网设备确定第二目标波束与第一目标波束不具有干扰互斥关系。可选地，接收信号强度可以用RSRP(Reference Signal Received Power，参考信号接收功率)值来衡量。另外，预设阈值可由协议预先规定，也可以在第二接入网设备中预先设定。若第二接入网设备确定第二目标波束与第一目标波束具有干扰互斥关系，则第二接入网设备记录第二目标波束与第一目标波束间的干扰互斥关系，例如将上述干扰互斥关系记录在干扰互斥信息中。
上述过程仅以确定一组波束间是否具有干扰互斥关系为例，对于其他波束 间是否具有干扰互斥关系，可以采用相似的过程。可选地，结合参考图2，在初始化测量过程中，第一接入网设备21使用波束1发送测量信号，第二接入网设备22按波束编号顺序逐一开启波束1至波束12接收第一接入网设备21发送的测量信号，并获取测量信号的接收信号强度，完成第一轮测量。之后，第一接入网设备21使用波束2发送测量信号，第二接入网设备22再次按波束编号顺序逐一开启波束1至波束12接收第一接入网设备21发送的测量信号，并获取测量信号的接收信号强度，完成第二轮测量。之后，第一接入网设备21依次使用波束3至波束12，重复上述测量过程。至此，完成一次初始化测量。第二接入网设备22记录所有具有干扰互斥关系的各组波束。
另外，第二接入网设备可以根据已确定的具有干扰互斥关系的至少一组波束，以及第二接入网设备的波束分布和第一接入网设备的波束分布，确定第二接入网设备与第一接入网设备间具有干扰互斥关系的至少一组其它波束。可选地，上述波束分布可以包括波束的夹角和/或波束的指向。例如，第二接入网设备可以根据已确定的具有干扰互斥关系的波束，结合第二接入网设备的波束分布和第一接入网设备的波束分布，推算第二接入网设备与第一接入网设备指向相同或接近的波束组，并将上述指向相同或接近的波束组确定为具有干扰互斥关系的波束组。示例性地，结合参考图2，假设已经确定第一接入网设备21的波束5和第二接入网设备22的波束10具有干扰互斥关系，则根据波束的夹角，可以推算出，第一接入网设备21的波束6和第二接入网设备22的波束10也具有干扰互斥关系。
另外，在本公开实施例中，对波束间的干扰互斥关系的记录方式不作限定。示例性地，结合参考图2，可以记录为如下形式：第一接入网设备：{波束5}<—>第二接入网设备：{波束11}，即表示第一接入网设备21的波束5与第二接入网设备22的波束11具有干扰互斥关系；或者，记录为如下形式：第一接入网设备：{波束5，波束6}<—>第二接入网设备：{波束10，波束11}，即表示第一接入网设备21的波束5和/或波束6与第二接入网设备22的波束10和/或波束11具有干扰互斥关系。
在步骤303中，若第二接入网设备存在使用第二波束与第二终端之间传输第二数据的需求，则第二接入网设备根据第一数据所占用的固定周期，确定第二数据占用的固定周期。
当第二接入网设备存在使用第二波束与第二终端之间传输第二数据的需 求时，第二接入网设备可以根据第一数据所占用的固定周期，对第二数据占用的固定周期进行规划，以避免第一数据和第二数据占用重叠的固定周期而导致相互间产生传输干扰。
下面，对第二接入网设备确定第二数据占用的固定周期的几种可能实现方式进行介绍说明。
在一种可能的实施方式中，当第二接入网设备存在使用第二波束与第二终端之间传输第二数据的需求时，第二接入网设备选择与第一数据所占用的固定周期不存在重叠的固定周期，作为第二数据占用的固定周期。示例性地，结合参考图4，第一接入网设备与第一终端使用波束5或波束6传输第一数据，且占用的固定周期为第一个固定周期、第二个固定周期、第四个固定周期和第六个固定周期，第二接入网设备存在使用第二波束与第二终端之间传输第二数据的需求时，不可以调度上述传输第一数据时占用的四个固定周期来传输第二数据，可以选择其他未被第一数据占用的固定周期，即第三个固定周期和第五个固定周期来传输第二数据。
在另一种可能的实施方式中，考虑到上行传输对邻小区中的传输干扰较大，而下行传输对邻小区中的传输干扰较小，因此第二接入网设备也可以采用下述方式确定第二数据占用的固定周期：
1、对于第二数据中的上行数据，第二接入网设备选择符合第一条件的固定周期，作为第二数据中的上行数据占用的固定周期；其中，第一条件包括与第一数据所占用的固定周期不存在重叠。示例性地，结合参考图5，第一接入网设备与第一终端使用波束5或波束6传输第一数据，占用的固定周期为第一个固定周期、第二个固定周期、第四个固定周期和第六个固定周期。其中，在第一个和第四个固定周期中有下行传输占用，也有上行传输占用；在第二个和第六个固定周期中，只有下行传输占用。当第二接入网设备存在使用波束10或波束11传输第二数据的需求时，对于第二数据中的上行数据，第二接入网设备可以选择未被第一数据占用的固定周期，即第三个固定周期和第五个固定周期，作为第二数据中的上行数据占用的固定周期。
2、对于第二数据中的下行数据，第二接入网设备选择符合第二条件的固定周期，作为第二数据中的下行数据占用的固定周期；其中，第二条件包括与第一数据中的上行数据所占用的固定周期不存在重叠。示例性地，结合参考图5，第一接入网设备与第一终端使用波束5或波束6传输第一数据，占用的固 定周期为第一个固定周期、第二个固定周期、第四个固定周期和第六个固定周期。其中，在第一个和第四个固定周期中有下行传输占用，也有上行传输占用；在第二个和第六个固定周期中，只有下行传输占用。当第二接入网设备存在使用波束10或波束11传输第二数据的需求时，对于第二数据中的下行数据，第二接入网设备可以选择已经被第一数据中的下行数据占用的第二个固定周期和第六个固定周期，作为第二数据中的下行数据占用的固定周期。当然，第二接入网设备还可以选择未被第一数据占用的固定周期，即第三个固定周期和第五个固定周期，作为第二数据中的下行数据占用的固定周期。
通过上述方式，可以在尽可能地避免传输干扰的前提下，提高固定周期的利用效率。
需要补充说明的一点是，第一接入网设备向第二接入网设备发送的传输状态指示信息中还可以包括上下行占用指示信息，该上下行占用指示信息用于指示传输第一数据所占用的每个固定周期对应的上下行占用类型。可选地，上下行占用类型可以包括2类：有上行传输占用和无上行传输占用。示例性地，上下行占用指示信息也可以采用bit map来表示，例如，1表示有上行传输占用，0表示无上行传输占用。结合参考图5，第一接入网设备与第一终端传输第一数据所占用的固定周期可以表示为100100，即第一个固定周期和第四个固定周期中有上行传输占用，第二个固定周期、第三个固定周期、第五个固定周期和第六个固定周期没有上行传输占用。
还需要补充说明的一点是，当第二数据属于指定类型的业务数据，且需要占用冲突固定周期进行传输时，第二接入网设备可以在冲突固定周期中，选择与第一数据所占用的频域资源不存在重叠的频域资源传输该第二数据。上述指定类型的业务数据可以是时延敏感的业务数据。其中，冲突固定周期是指与第一数据所占用的固定周期存在干扰冲突的固定周期。上述干扰冲突的判定规则可以是第一数据占用的固定周期和第二数据占用的固定周期重叠，也可以是第一数据中的上行数据占用的固定周期和第二数据中的上行数据占用的固定周期重叠。可选地，第二接入网设备在选择用于传输第二数据的频域资源时，可以尽可能地选择与第一数据所占用的频域资源非邻频的频域资源，以尽可能地减少或避免产生干扰。
另外，第二接入网设备执行上述步骤303的情形可以包括如下两种方式：
在一种可能的实施方式中，当第二接入网设备存在使用第二波束向第二终端发送第二数据的需求时，或者当第二接入网设备存在使用第二波束接收第二终端发送的第二数据的需求时，第二接入网设备均执行上述根据第一数据所占用的固定周期，确定第二数据占用的固定周期的步骤。
在另一种可能的实施方式中，当第二接入网设备存在使用第二波束向第二终端发送第二数据的需求时，第二接入网设备执行上述根据第一数据所占用的固定周期，确定第二数据占用的固定周期的步骤；当第二接入网设备存在使用第二波束接收第二终端发送的第二数据的需求时，第二接入网设备不执行上述根据第一数据所占用的固定周期，确定第二数据占用的固定周期的步骤。由于第一接入网设备与第一终端之间的传输，对第二接入网设备的上行接收干扰较小，因此第二接入网设备可以仅在有下行传输的需求时执行上述步骤303以规避干扰，而在有上行传输的需求时可以不必根据第一数据所占用的固定周期来规划第二数据占用的固定周期，直接认为第二数据不会受到第一数据的传输干扰。
在步骤304中，第二接入网设备在第二数据占用的固定周期中，与第二终端之间传输第二数据。
第二接入网设备确定第二数据占用的固定周期之后，按照该规划对固定周期进行占用来传输第二数据。
另外，第二接入网设备在使用每一个规划占用的固定周期与第二终端之间传输第二数据之前，可以执行CCA，也可以不执行CCA，本公开实施例对此不作限定。
需要说明的一点是，当第二接入网设备进行数据传输时，也可以向其相邻接入网设备发送传输状态指示信息，其相邻接入网设备也可以进行上述FBE机制下的数据传输流程。
综上所述，本公开实施例提供的技术方案中，通过接入网设备获取其邻近接入网设备的波束占用信息和周期占用信息，当存在使用具有干扰互斥关系的波束传输数据的需求时，根据邻近接入网设备传输数据所占用的固定周期，确定当前需要传输的数据占用的固定周期，从而有针对性地选择无传输干扰的固定周期来传输数据。相较于通过CCA在每个周期重复地进行干扰检测，采用本公开实施例提供的技术方案，可以在周期选择上就规避干扰，减少CCA所带来的处理开销，提升接入信道的成功率。
