具体实施方式
在本申请实施例使用的术语仅仅是出于描述特定实施例的目的，而非限制本申请。本申请和权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式，除非上下文清楚地表示其它含义。还应当理解，本文中使用的术语“和/或”是指包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解，尽管在本申请实施例可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本申请范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，此外，所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
在TDD系统中，帧结构被分成DL时隙、UL时隙和S时隙，DL时隙包括多个DL符号，在这些DL符号对应的时域资源处理下行数据，UL时隙包括多个UL符号，在这些UL符号对应的时域资源处理上行数据，S时隙包括至少一个F符号，F符号可以用于DL，也可以用于UL，还可以用于GP。当前，TDD系统工作在HD模式中，即在同一个时刻，相同时域资源仅能用于UL或者DL。
为了更加灵活的使用时域资源，并提高资源利用率，TDD系统需要在相同的时域资源同时用于UL和DL，也就是，在相同的时域资源同时处理上行数据和下行数据，即FD模式。
在TDD系统下，帧结构一旦确定，用户设备就可以按照帧结构进行数据收发，而帧结构被分成DL时隙、UL时隙和S时隙。在FD模式下，基站设备和用户设备也可以获得帧结构。对于采用HD模式的用户设备，基站设备根据帧结构调度用户设备进行发送或者接收。对于采用FD模式的用户设备来说，基站设备根据帧结构调度用户设备的发送，接收或者同时发送和接收。
综上所述，基站设备可以配置针对FD模式的帧结构，并将针对FD模式的帧结构通知给用户设备，以使用户设备能够获知当前时刻的帧结构，从而能够正确地进行数据收发。从另一个角度，用户设备在获知针对FD模式的帧结构之后，还可以获知当前时刻可能存在用户设备间的干扰，从而可以采用一些干扰消除技术来减轻其它用户设备造成的干扰，提高通信的可靠性。
本申请一个例子提出一种TDD帧结构配置方法，以在TDD系统中支持FD模式， 对于针对FD模式配置的帧结构，用于指示UL资源、DL资源以及FD资源。在该帧结构中，包括DL时隙、UL时隙、FD时隙和S时隙。DL时隙包括多个DL符号，在这些DL符号对应的时域资源处理下行数据，UL时隙包括多个UL符号，在这些UL符号对应的时域资源处理上行数据，FD时隙包括多个FD符号，FD符号用于上行数据和下行数据，在这些FD符号对应的时域资源可以同时处理上行数据和下行数据。S时隙包括至少一个F符号，F符号可以用于DL，可以用于UL，可以用于GP。在F符号用于DL时，表示F符号用于下行数据，处理下行数据；在F符号用于UL时，表示F符号用于上行数据，处理上行数据；在F符号用于GP时，作为上下行切换的保护时间。
本例子中的FD符号，指可以同时进行下行数据和上下数据传输的符号。
基于上述FD模式的帧结构，基站设备可以将固定FD符号的帧结构配置给用户设备，也就是说，帧结构包括的是固定FD符号(即FD符号直接配置在帧结构中)，即在UL符号、DL符号和F符号的基础上，扩展出FD符号。对于FD符号，基站设备和用户设备同时处理上行数据和下行数据。
下面，先介绍如下方案。
当前，在5G系统中，TDD的帧结构按照时隙分为UL时隙，DL时隙和S时隙，S时隙中可以包含F符号，且F符号可以用于UL，DL，或者GP。其中，帧结构可以通过TDD-UL-DL-ConfigCommon(上下行公共配置)/TDD-UL-DL-ConfigDedicated(上下行专用配置)的方式告知用户设备。
TDD-UL-DL-ConfigCommon中，可以最大配置两个帧结构的模式(pattern)，每个模式可以配置帧结构的周期，以及周期中每个时隙和符号的具体配置(DL符号，UL符号，或F符号)，从而确定帧结构。其中，一种帧结构的示例可以参见图1所示，上下行配比是1:4，S时隙是时隙3，符号#10和#11被配置成F符号，用于上下行切换的GP。
在TDD-UL-DL-ConfigDedicated中，可以对TDD-UL-DL-ConfigCommon中被配置成F的符号进行更改，将其配置成DL符号或者UL符号。
下面，对本申请一个例子的技术方案进行说明。
本例子中提出一种TDD帧结构配置方法，可以应用于基站设备，参见图2所示，为该TDD帧结构配置方法的流程示意图，该方法可以包括：
步骤201、确定基站设备对应的工作模式，该工作模式可以是使能FD模式或者关闭FD模式；其中，在该工作模式是使能FD模式时，允许时隙中的符号作为FD符号、 DL符号、UL符号、或者F符号；在该工作模式是关闭FD模式时，允许时隙中的符号作为DL符号、UL符号、或者F符号。
步骤202、若该工作模式是使能FD模式，则向用户设备发送使能FD模式指示信息，以使用户设备基于使能FD模式指示信息为用户设备使能FD模式。
步骤203、若该工作模式是使能FD模式，则在时隙的多个符号中包括FD符号时，在FD符号对应的时域资源能够同时处理上行数据和下行数据。
一个例子中，针对时隙中的F符号，在工作模式是使能FD模式时，允许时隙中的F符号用于DL、UL、或GP；在工作模式是关闭FD模式时，允许时隙中的F符号用于DL、UL、或GP。
一个例子中，向用户设备发送使能FD模式指示信息，可以包括：向用户设备发送上下行公共配置消息，该上下行公共配置消息携带使能FD模式指示信息。其中，上下行公共配置消息携带使能FD模式指示信息，可以包括：若上下行公共配置消息包括全双工模式字段，则上下行公共配置消息携带使能FD模式指示信息。或者，若上下行公共配置消息未包括全双工模式字段，则上下行公共配置消息未带使能FD模式指示信息。
一个例子中，在通过上下行公共配置消息携带使能FD模式指示信息时，上下行公共配置消息可以通过SIB信息(如SIB1消息)来发送，或者，上下行公共配置消息可以通过RRC重配消息来发送。
在通过SIB消息发送携带使能FD模式指示信息的上下行公共配置消息时，使能FD模式的生效时间，包括但不限于：在发送SIB消息的时隙的下一个时隙；或者，在发送SIB消息的时隙后的第M个时隙；其中，M是基站设备和用户设备之间约定的固定值，M为正整数；或者，在发送SIB消息的帧的下一个帧的第一个时隙；或者，在发送SIB消息的周期的下一个周期的第一个时隙。或者，在通过RRC重配消息发送携带使能FD模式指示信息的上下行公共配置消息时，使能FD模式的生效时间，包括但不限于：在接收RRC重配消息对应的RRC重配完成消息的时隙的下一个时隙；或者，在接收RRC重配消息对应的RRC重配完成消息的时隙后的第M个时隙，M是基站设备和用户设备之间约定的固定值，M为正整数。
一个例子中，步骤203之前，基站设备还可以确定目标帧结构，目标帧结构可以可以包括多个时隙，每个时隙可以包括多个符号；基站设备向用户设备发送上下行公共配置消息，该上下行公共配置消息包括目标帧结构对应的帧结构参数，以使用户设备基于 该帧结构参数确定目标帧结构；其中，在目标帧结构对应的多个时隙的符号中包括FD符号时，该帧结构参数可以包括与该FD符号对应的FD模式参数。在此基础上，可以基于目标帧结构进行数据处理。针对步骤203，在基于目标帧结构进行数据处理时，在时隙中的符号作为FD符号时，则在FD符号对应的时域资源能够同时处理上行数据和下行数据。在时隙中的符号作为DL符号时，则在DL符号对应的时域资源处理下行数据。在时隙中的符号作为UL符号时，则在UL符号对应的时域资源处理上行数据。
一个例子中，当目标帧结构对应的时隙的符号中包括多个FD符号时，多个FD符号是连续的。比如说，从目标帧结构的目标周期的第一个符号开始，向后配置K1个连续FD符号；和/或，从目标帧结构的目标周期的最后一个符号开始，向前配置K2个连续FD符号；其中，K1为正整数，K2为正整数。
一个例子中，FD模式参数包括第一全双工符号数量和第二全双工符号数量；在此基础上：若在目标帧结构中配置K1个连续FD符号，则第一全双工符号数量可以用于指示K1的取值；和/或，若在目标帧结构中配置K2个连续FD符号，则第二全双工符号数量可以用于指示K2的取值。
一个例子中，FD模式参数包括第一全双工时隙数量、第三全双工符号数量、第二全双工时隙数量和第四全双工符号数量。若在目标帧结构中配置K1个连续FD符号，则第一全双工时隙数量用于指示K1个FD符号占用的完整时隙数目，第三全双工符号数量用于指示K1个FD符号占用的非完整时隙中FD符号的数目；和/或，若在目标帧结构中配置K2个连续FD符号，则第二全双工时隙数量用于指示K2个FD符号占用的完整时隙数目，第四全双工符号数量用于指示K2个FD符号占用的非完整时隙中FD符号的数目。
一个例子中，在目标帧结构对应的多个时隙的符号中包括F符号，在向用户设备发送上下行公共配置消息之后，还可以向用户设备发送上下行专用配置消息，该上下行专用配置消息包括全双工参数，且全双工参数用于指示将F符号用于FD。
本申请一个例子中提出一种TDD帧结构配置方法，可以应用于支持FD模式的用户设备，参见图3所示，为该TDD帧结构配置方法的流程示意图，包括：
步骤301、从基站设备接收使能FD模式指示信息；其中，该使能FD模式指示信息是基站设备在工作模式是使能FD模式时向用户设备发送的。
步骤302、基于该使能FD模式指示信息为用户设备使能FD模式。
其中，在为用户设备使能FD模式之后，用户设备期待时隙中的符号作为FD符号、DL符号、UL符号、或者F符号。若没有为用户设备使能FD模式，则用户设备期待时隙中的符号作为DL符号、UL符号、或者F符号。
其中，若为用户设备使能FD模式，则用户设备期待时隙中的F符号用于DL、UL、或者GP。若没有为用户设备使能FD模式，则用户设备期待时隙中的F符号用于DL、UL、或者GP。
步骤303、在为用户设备使能FD模式之后，则在时隙的多个符号中包括FD符号时，在FD符号对应的时域资源能够同时处理上行数据和下行数据。在时隙的多个符号中包括DL符号时，在DL符号对应的时域资源处理下行数据。在时隙的多个符号中包括UL符号时，在UL符号对应的时域资源处理上行数据。
若没有为用户设备使能FD模式，在时隙的多个符号中包括DL符号时，在DL符号对应的时域资源处理下行数据；在时隙的多个符号中包括UL符号时，在UL符号对应的时域资源处理上行数据。
若为用户设备使能FD模式，或者没有为用户设备使能FD模式，在时隙中的F符号用于DL时，在F符号对应的时域资源处理下行数据；在时隙中的F符号用于UL时，在F符号对应的时域资源处理上行数据。
一个例子中，从基站设备接收使能FD模式指示信息，可以包括：从基站设备接收上下行公共配置消息，该上下行公共配置消息携带使能FD模式指示信息。其中，上下行公共配置消息携带使能FD模式指示信息，可以包括：若上下行公共配置消息包括全双工模式字段，则上下行公共配置消息携带使能FD模式指示信息。或者，若上下行公共配置消息未包括全双工模式字段，则上下行公共配置消息未携带使能FD模式指示信息。
一个例子中，在通过上下行公共配置消息携带使能FD模式指示信息时，上下行公共配置消息可以通过SIB信息(如SIB1消息)来接收，或者，上下行公共配置消息可以通过RRC重配消息来接收。
在通过SIB消息接收携带使能FD模式指示信息的上下行公共配置消息时，用户设备使能FD模式的生效时间，可以包括但不限于：在接收SIB消息的时隙的下一个时隙；或者，在接收SIB消息的时隙后的第M个时隙，M是基站设备和用户设备之间约定的固定值，M为正整数；或者，在接收SIB消息的帧的下一个帧的第一个时隙；或，在接 收SIB消息的周期的下一个周期的第一个时隙。
在通过RRC重配消息接收携带使能FD模式指示信息的上下行公共配置消息时，用户设备使能FD模式的生效时间，可以包括但不限于：在发送RRC重配消息对应的RRC重配完成消息的时隙的下一个时隙；或者，在发送RRC重配消息对应的RRC重配完成消息的时隙后的第M个时隙，M是基站设备和用户设备之间约定的固定值，M为正整数。
一个例子中，步骤303之前，还可以从基站设备接收上下行公共配置消息，上下行公共配置消息包括目标帧结构对应的帧结构参数，基于帧结构参数确定目标帧结构；其中，目标帧结构可以包括多个时隙，每个时隙可以包括多个符号；在目标帧结构对应的多个时隙的符号中包括FD符号时，帧结构参数包括与FD符号对应的FD模式参数，且FD模式参数用于指示目标帧结构对应的多个时隙中的FD符号，即用户设备可以基于FD模式参数确定出目标帧结构对应的多个时隙中的FD符号。基于目标帧结构进行数据处理。
针对步骤303，在基于目标帧结构进行数据处理时，在时隙中的符号作为FD符号，则在FD符号对应的时域资源能够同时处理上行数据和下行数据。在时隙中的符号作为DL符号时，则在DL符号对应的时域资源处理下行数据。在时隙中的符号作为UL符号时，则在UL符号对应的时域资源处理上行数据。
一个例子中，当目标帧结构对应的时隙的符号中包括多个FD符号时，则期待多个FD符号是连续的。比如说，期待K1个连续FD符号是从目标帧结构的目标周期的第一个符号开始向后配置；和/或，期待K2个连续FD符号是从目标帧结构的目标周期的最后一个符号开始向前配置；其中，K1和K2为正整数。
FD模式参数包括第一全双工符号数量和第二全双工符号数量，若目标帧结构中包括K1个连续FD符号，则基于第一全双工符号数量确定K1的取值，基于K1的取值从目标帧结构对应的多个时隙中确定出FD符号；若目标帧结构中包括K2个连续FD符号，则基于第二全双工符号数量确定K2的取值，基于K2的取值从目标帧结构对应的多个时隙中确定出FD符号。
FD模式参数包括第一全双工时隙数量、第三全双工符号数量、第二全双工时隙数量和第四全双工符号数量，若目标帧结构中包括K1个连续FD符号，则基于第一全双工时隙数量确定K1个FD符号占用的完整时隙数目，基于第三全双工符号数量确定K1 个FD符号占用的非完整时隙中FD符号数目；基于第一全双工时隙数量和第三全双工符号数量从目标帧结构对应的多个时隙中确定出FD符号；若目标帧结构中包括K2个连续FD符号，则基于第二全双工时隙数量确定K2个FD符号占用的完整时隙数目，基于第四全双工符号数量确定K2个FD符号占用的非完整时隙中FD符号数目；基于第二全双工时隙数量和第四全双工符号数量从目标帧结构对应的多个时隙中确定出FD符号。
一个例子中，在目标帧结构对应的多个时隙的符号中包括F符号，从基站设备接收上下行公共配置消息之后，还可以从基站设备接收上下行专用配置消息，该上下行专用配置消息包括全双工参数，且该全双工参数用于指示将F符号用于FD。
本申请一个例子中提出一种TDD帧结构配置方法，可以应用于不支持FD模式的用户设备，参见图4所示，为TDD帧结构配置方法的流程示意图，包括：
步骤401、从基站设备接收使能FD模式指示信息；其中，该使能FD模式指示信息是基站设备在工作模式是使能FD模式时向用户设备发送的。
步骤402、忽略使能FD模式指示信息，即不会基于使能FD模式指示信息为用户设备使能FD模式。其中，用户设备期待时隙中的符号作为DL符号、UL符号、或者F符号；在时隙中的符号作为DL符号时，在所述DL符号对应的时域资源处理下行数据；在时隙中的符号作为UL符号时，在所述UL符号对应的时域资源处理上行数据。其中，用户设备期待时隙中的F符号用于DL、UL、或者GP；在时隙中的F符号用于DL时，在F符号对应的时域资源处理下行数据；在时隙中的F符号用于UL时，在F符号对应的时域资源处理上行数据。
由以上技术方案可见，可以将基站设备对应的工作模式区分为使能FD模式和关闭FD模式，在工作模式是使能FD模式时，允许时隙中的符号作为FD符号，即将时隙中的符号的功能扩展到作为FD符号，而在时隙中的符号作为FD符号时，基站设备和用户设备可以在FD符号对应的时域资源同时处理上行数据和下行数据，这样，相同时域资源能够同时处理上行数据和下行数据，从而更加有效的利用时域资源，提高资源利用率，能够提高网络覆盖和网络容量，同时降低传输时延，如降低上行传输时延。
以下结合具体例子，对上述技术方案进行说明。
本申请一个例子中提出了一种TDD帧结构配置方法，使帧结构能够应用于FD模式，FD符号在帧结构中明确指示，如通过TDD-UL-DL-ConfigCommon(上下行公共配置)和/或TDD-UL-DL-ConfigDedicated(上下行专用配置)来配置固定的FD符号。针对FD 模式的帧结构，可以包括多个时隙，每个时隙可以包括多个符号，这些符号可以是F符号、DL符号、UL符号和FD符号。其中，基站设备和用户设备在DL符号对应的时域资源处理下行数据，在UL符号对应的时域资源处理上行数据。若基站设备使能FD模式，则基站设备在FD符号对应的时域资源可以同时处理上行数据和下行数据。若用户设备使能FD模式，则用户设备在FD符号对应的时域资源可以同时处理上行数据和下行数据。
对于F符号来说，F符号用于DL、UL、或者GP。在F符号用于DL时，基站设备和用户设备可以处理下行数据；在F符号用于UL时，基站设备和用户设备可以处理上行数据；在F符号用于GP时，可以用于上下行切换的保护。
其中，F符号用于GP的原因在于：在TDD系统的帧结构中，通过GP符号实现上下行切换的保护。在基站设备工作在FD模式时，会有单独的天线和射频电路来进行发送和接收，无需通过GP符号实现上下行切换的保护。对于FD模式的用户设备，工作方式与基站设备相同，无需通过GP符号实现上下行切换的保护。对于HD模式的用户设备，使用足够的时间为射频进行发送和接收之间的切换，即使用GP符号实现上下行切换的保护。综上所述，为了支持HD模式的用户设备，FD模式的帧结构仍然支持GP符号，因此，允许F符号用于GP。
比如说，为了兼容不同类型的用户设备，FD模式中的帧结构考虑分配GP给用户设备(如HD模式的用户设备)做上下行的切换的保护。参见图5所示，为帧结构的示意图，若将时隙2的符号#7-#13配置成FD符号(即将DL符号变为FD符号)，且由于FD符号同时处理上行数据和下行数据，此时至少将符号#6用于GP。相反，如果基站设备在已经配置成FD符号的位置发送下行数据，即用户设备接收下行数据，那么，也会在FD符号后留出GP以便于用户设备进行上下行切换的保护。例如，如果将时隙4的符号#0-#7配置FD符号(即将UL符号变为FD符号)，并通过这些FD符号发送下行数据，那么，在符号#8-#13接收上行数据(在符号#8-#13作为UL符号或者FD符号时，均可以接收上行数据)时，至少在符号#8预留GP资源供用户设备进行上下行切换的保护。
一种例子中，对于FD符号来说，FD符号中的一部分频域资源可以用于UL，另一部分频域资源可以用于DL，中间一部分频域资源可以作为上下行保护间隔，从而能够避免产生子带间(Inter Sub-band)干扰。
一个例子中，TDD帧结构配置方法可以包括以下步骤：
步骤S11、基站设备确定本基站设备对应的工作模式，该工作模式是使能FD模式或者关闭FD模式。比如说，可以根据业务需要，为基站设备配置工作模式，对此过程不做限制。其中，在基站设备对应的工作模式是使能FD模式时，允许时隙中的符号是FD符号、F符号、DL符号和UL符号，以及，允许时隙中的F符号用于DL、UL、或者GP。在基站设备对应的工作模式是关闭FD模式时，允许时隙中的符号是F符号、DL符号和UL符号，即不允许时隙中的符号是FD符号，以及，允许时隙中的F符号用于DL、UL、或者GP。
步骤S12、基站设备确定目标帧结构，目标帧结构可以包括多个时隙，每个时隙可以包括多个符号，该符号可以是FD符号、F符号、DL符号或者UL符号。
目标帧结构是用于实现数据处理(如数据发送和/或数据接收)的帧结构，基站设备会确定出目标帧结构，基于该目标帧结构实现数据处理，用户设备也会确定出目标帧结构，基于该目标帧结构实现数据处理，并且，基站设备确定的目标帧结构与用户设备确定的目标帧结构相同。
一个例子中，目标帧结构对应的时隙的符号中可以包括一个FD符号，目标帧结构对应的时隙的符号中也可以包括多个FD符号。当目标帧结构对应的时隙的符号中包括多个FD符号时，多个FD符号可以是连续的。当多个FD符号连续时，可以降低GP符号的数目。当然，多个FD符号也可以不是连续的，即多个FD符号之间存在其它类型的符号。
一个例子中，可以从目标帧结构的目标周期的第一个符号开始，向后配置K1个连续FD符号，K1为正整数。其中，目标周期可以是目标帧结构的任意周期。K1个连续FD符号可能只占用一个时隙的符号，也可能占用多个时隙的符号。比如说，当目标帧结构的目标周期的第一个时隙是下行时隙时，就可以从目标帧结构的目标周期的第一个下行时隙开始，向后配置K1个连续FD符号。当目标帧结构的目标周期的第一个时隙是S时隙时，就可以从目标帧结构的目标周期的第一个S时隙开始，向后配置K1个连续FD符号。
一个例子中，可以从目标帧结构的目标周期的最后一个符号开始，向前配置K2个连续FD符号，K2为正整数。其中，目标周期可以是目标帧结构的任意周期。K2个连续FD符号可能只占用一个时隙的符号，也可能占用多个时隙的符号。比如说，当目标帧结构的目标周期的最后一个时隙是上行时隙时，就可以从目标帧结构的目标周期的最后一个上行时隙开始，向前配置K2个连续FD符号。当目标帧结构的目标周期的最后 一个时隙是S时隙时，就可以从目标帧结构的目标周期的最后一个S时隙开始，向前配置K2个连续FD符号。
一个例子中，可以从目标帧结构的目标周期的第一个符号开始，向后配置K1个连续FD符号，K1为正整数。以及，可以从目标帧结构的目标周期的最后一个符号开始，向前配置K2个连续FD符号，K2为正整数。
比如说，当连续FD符号为一组时，从目标帧结构的目标周期的第一个符号开始，向后配置多个(如K1个，K1表示从第一个符号开始的连续符号数量)连续FD符号；或者，从目标帧结构的目标周期的最后一个符号开始，向前配置多个(如K2个，K2表示从最后一个符号开始的连续符号数量)连续FD符号。
又例如，当连续FD符号为两组时，从目标帧结构的目标周期的第一个符号开始，向后配置多个(如K1个，这里只是用K1表示连续符号数量，而不表示一组配置和两组配置时，会配置相同数量)连续FD符号；以及，从目标帧结构的目标周期的最后一个符号开始，向前配置多个(如K2个)连续FD符号。
参见图6A所示，是时域资源配置的示意图，图6A给出了在DL符号和UL符号中配置FD符号的示例，例如，目标帧结构的周期是1ms，即2个时隙，阴影填充部分(如时隙1/时隙3中的符号#10-#13，时隙0/时隙2中的符号#0-#4)表示已配置的FD符号。从图6A可以看出，可以从目标帧结构的目标周期(时隙0和时隙1组成一个目标周期，时隙2和时隙3组成一个目标周期)的第一个符号(如时隙0的第一个符号、时隙2的第一个符号)开始向后配置连续FD符号，如向后配置5个连续FD符号。此外，可以从目标帧结构的目标周期的最后一个符号(如时隙1的最后一个符号、时隙3的最后一个符号)开始向前配置连续FD符号，如向前配置4个连续FD符号。
综上可以看出，可以在目标帧结构中配置最多两个连续FD资源，比如说，在目标帧结构中配置两个连续的FD资源时，第一个FD资源从目标帧结构的目标周期内的第一个符号开始向后配置，第二个FD资源从目标帧结构的目标周期内的最后一个符号开始向前配置。在目标帧结构中配置一个连续的FD资源时，FD资源从目标帧结构的目标周期内的第一个符号开始向后配置，或者，FD资源从目标帧结构的目标周期内的最后一个符号开始向前配置。对于目标帧结构的目标周期，以该目标周期包括两个时隙为例，则可以在两个时隙中配置连续FD符号，参见图6B所示，示出了两个时隙组成目标周期的示例。
步骤S13、基站设备向用户设备发送上下行公共配置消息。
一个例子中，若基站设备对应的工作模式是使能FD模式，则上下行公共配置消息可以携带使能FD模式指示信息。比如说，若上下行公共配置消息包括全双工模式字段，则上下行公共配置消息携带使能FD模式指示信息。
或者，若基站设备对应的工作模式是关闭FD模式，则上下行公共配置消息可以不携带使能FD模式指示信息。比如说，若上下行公共配置消息未包括全双工模式字段，则上下行公共配置消息未带使能FD模式指示信息。
上下行公共配置消息可以是TDD-UL-DL-ConfigCommon，可以在上下行公共配置消息中额外增加全双工模式字段，通过全双工模式字段表示使能FD模式指示信息，全双工模式字段可以是fullDuplexPattern。
上下行公共配置消息可以通过SIB信息(如SIB1消息)来发送，或者，上下行公共配置消息可以通过RRC重配消息来发送。
在通过SIB消息发送携带使能FD模式指示信息的上下行公共配置消息时，可以明确FD模式的生效时间，如采用如下方案确定使能FD模式的生效时间：
方案1：在发送SIB消息的时隙的下一个时隙，即SIB消息的发送时隙的下一个时隙，也就是说，在发送SIB消息的时隙的下一个时隙生效使能FD模式。参见图7所示，SIB消息是每隔8帧发送一次，即80ms发送一次SIB消息，如图7中第N帧和第N+8帧的时隙0发送SIB消息，显然，发送SIB消息的时隙就是第N帧和第N+8帧的时隙0，因此，FD模式在第N帧的时隙1生效。
方案2：在发送SIB消息的时隙后的第M个时隙，即SIB消息的发送时隙后的第M个时隙，也就是说，在发送SIB消息的时隙后的第M个时隙生效使能FD模式。其中，M可以是基站设备和用户设备之间约定的固定值，M可以为正整数，对此不做限制。比如说，M是根据用户设备的能力，在基站设备和用户设备之间约定好的固定值，基站设备不通过特定信令将M的取值告知用户设备，如M为4、5、6、7等。
参见图7所示，以M＝5为例，由于发送SIB消息的时隙是第N帧的时隙0，因此，FD模式在第N帧的时隙5(时隙0后的第5个时隙)生效。
方案3：在发送SIB消息的帧的下一个帧的第一个时隙，即SIB消息的发送帧后第一个帧的第一个时隙，即，在发送SIB消息的帧的下一个帧的第一个时隙生效使能FD模式。参见图7所示，发送SIB消息的时隙是第N帧的时隙0，FD模式在第N+1 帧的时隙0生效。
方案4：在发送SIB消息的周期的下一个周期的第一个时隙，即SIB消息的发送周期后第一个周期的第一个时隙，也就是说，在发送SIB消息的周期的下一个周期的第一个时隙生效使能FD模式。参见图7所示，SIB消息消息的时隙是第N帧的时隙0，因此，当前周期的下一个周期是第N+8帧，FD模式在第N+8帧的时隙0生效。
在通过RRC重配消息发送携带使能FD模式指示信息的上下行公共配置消息时，可以明确FD模式的生效时间，如采用如下方案确定使能FD模式的生效时间：方案1：在接收RRC重配消息对应的RRC重配完成消息的时隙的下一个时隙，即RRC重配完成消息的接收时隙的下一个时隙，也就是说，在接收RRC重配完成消息的时隙的下一个时隙生效使能FD模式。方案2：在接收RRC重配消息对应的RRC重配完成消息的时隙后的第M个时隙，即RRC重配完成消息的接收时隙后的第M个时隙，也就是说，在接收RRC重配完成消息的时隙后的第M个时隙生效使能FD模式。其中，M可以是基站设备和用户设备之间约定的固定值，M可以为正整数，对此不做限制。
其中，基站设备通过RRC重配消息发送携带使能FD模式指示信息的上下行公共配置消息时，用户设备在接收到RRC重配消息之后，可以向基站设备发送RRC重配完成消息，而基站设备可以接收RRC重配消息对应的RRC重配完成消息，以接收RRC重配消息对应的RRC重配完成消息的时隙作为参考依据。
一个例子中，上下行公共配置消息可以携带目标帧结构对应的帧结构参数，该帧结构参数用于指示目标帧结构，对此帧结构参数不做限制，只要用户设备能够基于帧结构参数确定出目标帧结构即可。
在目标帧结构对应的多个时隙的符号中包括FD符号时，该帧结构参数可以包括与FD符号对应的FD模式参数，FD模式参数用于指示目标帧结构对应的多个时隙中的FD符号，使用户设备确定出时隙中的FD符号。
对于FD符号对应的FD模式参数，考虑时域配置的粒度不同，可以通过符号粒度或者时隙加符号粒度来指示FD符号对应的FD模式参数。
情况1：通过符号粒度来指示FD符号对应的FD模式参数。
在TDD-UL-DL-ConfigCommon的基础上，在上下行公共配置消息中引入FD符号对应的FD模式参数，包括两个主要参数：
nrofFullDuplexSymbolsOutofDlSymbols：该参数是第一全双工符号数量，若在目 标帧结构中配置K1个连续FD符号，则该参数用于指示K1的取值，即该参数表示从帧结构的目标周期的第一个符号向后开始的连续FD符号的个数，该参数的取值是正整数类型，范围是从0到10ms周期内最大的符号数。该参数可以表示为maxNrofSlots*maxNrofSymbols，maxNrofSlots表示10ms周期中最大时隙数目，maxNrofSymbols表示单个时隙中的符号数，该参数可选。
nrofFullDuplexSymbolsOutofUlSymbols：该参数是第二全双工符号数量，若在目标帧结构中配置K2个连续FD符号，则该参数用于指示K2的取值，即该参数表示从帧结构的目标周期的最后一个符号向前开始的连续FD符号的个数，该参数的取值是正整数类型，范围是从0到10ms周期内最大的符号数。该参数可以表示为maxNrofSlots*maxNrofSymbols，maxNrofSlots表示10ms周期中最大时隙数目，maxNrofSymbols表示单个时隙中的符号数，该参数可选。
针对上述情况1，上下行公共配置消息的伪码可以参见如下所示：
Figure PCTCN2022090609-appb-000001
在上述上下行公共配置消息中，fullDuplexPattern1和fullDuplexPattern2表示全双工模式字段，用于表示使能FD模式指示信息，其中fullDuplexPattern1对应pattern1，即fullDuplexPattern1是基于pattern1中配置的帧结构参数进一步配置FD参数。相应的，fullDuplexPattern2对应pattern2，即fullDuplexPattern2是基于pattern2中配置的帧结构 参数进一步配置FD参数。此外，nrofFullDuplexSymbolsOutofDlSymbols和nrofFullDuplexSymbolsOutofUlSymbols表示FD模式参数，结合图6A所示的目标帧结构可以看出，可以将nrofFullDuplexSymbolsOutofDlSymbols的值设置成5，将nrofFullDuplexSymbolsOutofUlSymbols的值设置成4。
情况2：通过时隙加符号粒度来指示FD符号对应的FD模式参数。
在TDD-UL-DL-ConfigCommon的基础上，在上下行公共配置消息中引入FD符号对应的FD模式参数，可以通过时隙加符号的方式来表示FD模式参数，即通过时隙数量加上符号数量共同构成，包括四个主要参数：
nrofFullDuplexSlotOutofDlSlots：该参数是第一全双工时隙数量，若在目标帧结构中配置K1个连续FD符号，则该参数用于指示K1个FD符号占用的完整时隙数目。假设完整时隙包括14个符号，那么，若K1小于14，则K1个FD符号占用的完整时隙数目是0，即该参数的取值可以是0；若K1大于等于14且小于28，则K1个FD符号占用的完整时隙数目是1，即该参数的取值可以是1；若K1大于等于28且小于42，则K1个FD符号占用的完整时隙数目是2，即该参数的取值可以是2，以此类推。该参数表示从帧结构的目标周期的第一个符号向后开始的连续FD时隙的数目，该参数的取值为正整数类型，范围是从0到10ms周期内最大的时隙数，即0…maxNrofSlots，该参数可选。
nrofFullDuplexSymbolinDlorSpecialSlots：该参数是第三全双工符号数量，若在目标帧结构中配置K1个连续FD符号，则该参数用于指示K1个FD符号占用的非完整时隙中FD符号的数目。假设完整时隙包括14个符号，那么，若K1小于14，则K1个FD符号占用的非完整时隙中FD符号的数目是K1，即该参数的取值可以是K1；若K1大于等于14且小于28，则K1个FD符号占用的非完整时隙中FD符号的数目是(K1-14)，即该参数的取值可以是(K1-14)；若K1大于等于28且小于42，则K1个FD符号占用的非完整时隙中FD符号的数目是(K1-28)，即该参数的取值可以是(K1-28)，以此类推。显然，nrofFullDuplexSlotOutofDlSlots的取值乘以完整时隙中的符号总数量(如14)，再加上nrofFullDuplexSymbolinDlorSpecialSlots的取值，就是K1。
该参数表示从nrofFullDuplexSlotOutofDlSlots之后的第一个符号开始连续的FD符号的数目，该参数的取值为正整数类型，范围是从0到时隙内最大符号数，即0…maxNrofSymbols，该参数可选，且依赖于nrofFullDuplexSlotOutofDlSlots。
如果nrofFullDuplexSlotOutofDlSlots没有配置，则不可以配置该参数。但是，如果nrofFullDuplexSlotOutofDlSlots配置，该参数可以配置也可以不配置。
nrofFullDuplexSlotOutofUlSlots：该参数是第二全双工时隙数量，若在目标帧结构中配置K2个连续FD符号，则该参数用于指示K2个FD符号占用的完整时隙数目。若K2小于14，则K2个FD符号占用的完整时隙数目是0，即该参数的取值是0；若K2大于等于14且小于28，则K2个FD符号占用的完整时隙数目是1，即该参数的取值是1，以此类推。该参数表示从帧结构的目标周期的最后一个符号向前开始的连续FD时隙的数目，该参数的取值为正整数类型，范围是从0到10ms周期内最大的时隙数，即0…maxNrofSlots，该参数可选。
nroffullDuplexSymbolinUlorSpecialSlots：该参数是第四全双工符号数量，若在目标帧结构中配置K2个连续FD符号，则该参数用于指示K2个FD符号占用的非完整时隙中FD符号的数目。若K2小于14，则K2个FD符号占用的非完整时隙中FD符号的数目是K2，即该参数的取值是K2；若K2大于等于14且小于28，则K2个FD符号占用的非完整时隙中FD符号的数目是(K2-14)，即该参数的取值可以是(K2-14)，以此类推。显然，nrofFullDuplexSlotOutofUlSlots的取值乘以完整时隙中的符号总数量(如14)，再加上nroffullDuplexSymbolinUlorSpecialSlots的取值，就是K2。
该参数表示从nrofFullDuplexSlotOutofUlSlots之前最后一个符号开始向前连续FD符号的数目，取值为正整数类型，范围是从0到时隙内最大符号数，即0…maxNrofSymbols，该参数可选，且依赖于nrofFullDuplexSlotOutofUlSlots。
如果nrofFullDuplexSlotOutofUlSlots没有配置，则不可以配置该参数。但是，如果nrofFullDuplexSlotOutofUlSlots配置了，该参数可以配置也可以不配置。
针对上述情况2，上下行公共配置消息的伪码可以参见如下所示：
Figure PCTCN2022090609-appb-000002
Figure PCTCN2022090609-appb-000003
其中fullDuplexPattern1对应pattern1，即fullDuplexPattern1是基于pattern1中配置的帧结构参数进一步配置FD参数。相应的，fullDuplexPattern2对应pattern2，即fullDuplexPattern2是基于pattern2中配置的帧结构参数进一步配置FD参数。在TDD-UL-DL-Pattern-FullDuplex中，前面两个参数作为一对配置，与下行时隙中的FD符号有关的FD模式参数，后面两个参数作为另一对配置，与上行时隙中的FD符号有关的FD模式参数。结合图6A所示的目标帧结构，将nrofFullDuplexSlotOutofDlSlots和nrofFullDuplexSymbolinDlorSpecialSlot的值分别设置成0和5。此外，还可以将nrofFullDuplexSlotsOutofUlSlots和nroffullDuplexSymbolinUlorSpecialSlots的值分别设置成0和4。
步骤S14、用户设备从基站设备接收上下行公共配置消息。
步骤S15、若上下行公共配置消息包括使能FD模式指示信息，则用户设备基于该使能FD模式指示信息为本用户设备使能FD模式。
若上下行公共配置消息包括全双工模式字段，则用户设备确定上下行公共配置消息携带使能FD模式指示信息，并为本用户设备使能FD模式。或者，若上下行公共配置消息未包括全双工模式字段，则用户设备确定上下行公共配置消息未携带使能FD模式指示信息，不会为本用户设备使能FD模式。
其中，若为用户设备使能FD模式，则用户设备期待时隙中的符号是FD符号、F符号、DL符号和UL符号，以及，期待时隙中的F符号用于DL、UL、或者GP。若没有为用户设备使能FD模式，则用户设备期待时隙中的符号是F符号、DL符号和UL符号，以及，期待时隙中的F符号用于DL、UL、或者GP。
在通过上下行公共配置消息携带使能FD模式指示信息时，上下行公共配置消息可以通过SIB信息(如SIB1消息)来接收，或者，上下行公共配置消息可以通过RRC 重配消息来接收。在通过SIB消息接收携带使能FD模式指示信息的上下行公共配置消息时，还可以明确FD模式的生效时间，比如说，采用如下方案确定用户设备使能FD模式的生效时间：方案1：在接收SIB消息的时隙的下一个时隙，即SIB消息的接收时隙的下一个时隙，即，在接收SIB消息的时隙的下一个时隙生效使能FD模式。方案2：在接收SIB消息的时隙后的第M个时隙，即SIB消息的接收时隙后的第M个时隙，即，在接收SIB消息的时隙后的第M个时隙生效使能FD模式。M是基站设备和用户设备之间约定的固定值，M为正整数。方案3：在接收SIB消息的帧的下一个帧的第一个时隙，即SIB消息的接收帧的下一个帧的第一个时隙，即，在接收SIB消息的帧的下一个帧的第一个时隙生效使能FD模式。方案4：在接收SIB消息的周期的下一个周期的第一个时隙，即SIB消息的接收周期的下一个周期的第一个时隙，即，在接收SIB消息的周期的下一个周期的第一个时隙生效使能FD模式。
在通过RRC重配消息接收携带使能FD模式指示信息的上下行公共配置消息时，还可以明确FD模式的生效时间，比如说，采用如下方案确定用户设备使能FD模式的生效时间：在发送RRC重配消息对应的RRC重配完成消息的时隙的下一个时隙；或者，在发送RRC重配消息对应的RRC重配完成消息的时隙后的第M个时隙，M是基站设备和用户设备之间约定的固定值，M为正整数。
其中，基站设备通过RRC重配消息发送携带使能FD模式指示信息的上下行公共配置消息时，用户设备在接收到RRC重配消息之后，可以向基站设备发送RRC重配完成消息，因此，以用户设备发送RRC重配消息对应的RRC重配完成消息的时隙作为参考依据。
步骤S16、用户设备从上下行公共配置消息中解析出帧结构参数，并基于该帧结构参数确定目标帧结构。其中，目标帧结构可以包括多个时隙，每个时隙可以包括多个符号，该符号可以是FD符号、F符号、DL符号或者UL符号。
在目标帧结构对应的多个时隙的符号中包括FD符号时，该帧结构参数还可以包括与FD符号对应的FD模式参数，且该FD模式参数用于指示目标帧结构对应的多个时隙中的FD符号，也就是说，用户设备可以基于FD模式参数确定出目标帧结构对应的多个时隙中的FD符号。
比如说，当目标帧结构对应的时隙的符号中包括多个FD符号时，则用户设备期待多个FD符号是连续的。若目标帧结构中包括K1个连续FD符号，则用户设备期待K1个连续FD符号是从目标帧结构的目标周期的第一个符号开始向后配置；和/或，若 目标帧结构中包括K2个连续FD符号，则用户设备期待K2个连续FD符号是从目标帧结构的目标周期的最后一个符号开始向前配置。
比如说，参见步骤S13中的情况1，FD模式参数包括第一全双工符号数量和第二全双工符号数量，在此基础上，若目标帧结构中包括K1个连续FD符号，则用户设备可以基于第一全双工符号数量确定K1的取值，基于K1的取值就可以从目标帧结构对应的多个时隙中确定出FD符号。若目标帧结构中包括K2个连续FD符号，则用户设备可以基于第二全双工符号数量确定K2的取值，基于K2的取值就可以从目标帧结构对应的多个时隙中确定出FD符号。
又例如，参见步骤S13中的情况2，FD模式参数可以包括第一全双工时隙数量、第三全双工符号数量、第二全双工时隙数量和第四全双工符号数量，在此基础上，若目标帧结构中包括K1个连续FD符号，则基于第一全双工时隙数量确定K1个FD符号占用的完整时隙数目，并基于第三全双工符号数量确定K1个FD符号占用的非完整时隙中FD符号数目，基于第一全双工时隙数量和第三全双工符号数量就可以从目标帧结构对应的多个时隙中确定出FD符号，关于该确定方式，可以参见步骤S13中的情况2。若目标帧结构中包括K2个连续FD符号，则基于第二全双工时隙数量确定K2个FD6符号占用的完整时隙数目，并基于第四全双工符号数量确定K2个FD符号占用的非完整时隙中FD符号数目，基于第二全双工时隙数量和第四全双工符号数量就可以从目标帧结构对应的多个时隙中确定出FD符号，关于该确定方式，可以参见步骤S13中的情况2。
步骤S17、基站设备和用户设备基于目标帧结构进行数据处理。
一个例子中，若基站设备对应的工作模式是使能FD模式，且为用户设备使能FD模式，则目标帧结构的多个符号可以是FD符号、F符号、DL符号或者UL符号。其中，在基于目标帧结构进行数据处理时，若时隙中的符号是FD符号时，基站设备在FD符号对应的时域资源可以同时处理上行数据和下行数据，用户设备在FD符号对应的时域资源可以同时处理上行数据和下行数据。在时隙中的符号是DL符号时，基站设备在DL符号对应的时域资源处理下行数据，且用户设备在DL符号对应的时域资源处理下行数据。在时隙中的符号是UL符号时，基站设备在UL符号对应的时域资源处理上行数据，且用户设备在UL符号对应的时域资源处理上行数据。此外，若时隙中的F符号用于DL，则基站设备在F符号对应的时域资源处理下行数据，且用户设备在F符号对应的时域资源处理下行数据。若时隙中的F符号用于UL，则基站设备在F符号对 应的时域资源处理上行数据，且用户设备在F符号对应的时域资源处理上行数据。
一个例子中，若基站设备对应的工作模式是关闭FD模式，且没有为用户设备使能FD模式，则目标帧结构的多个符号可以是F符号、DL符号或者UL符号。在基于目标帧结构进行数据处理时，在时隙中的符号是DL符号时，基站设备在DL符号对应的时域资源处理下行数据，且用户设备在DL符号对应的时域资源处理下行数据。在时隙中的符号是UL符号时，基站设备在UL符号对应的时域资源处理上行数据，且用户设备在UL符号对应的时域资源处理上行数据。此外，在时隙中的符号为F符号时，若时隙中的F符号用于DL，则基站设备在F符号对应的时域资源处理下行数据，且用户设备在F符号对应的时域资源处理下行数据。若时隙中的F符号用于UL，则基站设备在F符号对应的时域资源处理上行数据，且用户设备在F符号对应的时域资源处理上行数据。
在上面例子中，针对步骤S11-步骤S17，是针对支持FD模式的用户设备，关于不支持FD模式的用户设备，用户设备从基站设备接收到上下行公共配置消息时，忽略使能FD模式指示信息和FD模式参数，也不会基于使能FD模式指示信息为用户设备使能FD模式。用户设备期待时隙中的符号是F符号、DL符号和UL符号，用户设备期待时隙中的F符号用于DL、UL、或者GP。
用户设备基于目标帧结构进行数据处理时，在时隙中的符号为F符号时，若时隙中的F符号用于DL，用户设备在F符号对应的时域资源处理下行数据。若时隙中的F符号用于UL，用户设备在F符号对应的时域资源处理上行数据。
在FD模式使能后，从基站设备的角度，基站设备可以根据业务需求对FD符号进行灵活调度，并在FD符号中同时进行发送和接收操作。
对于不支持FD模式的用户设备，用户设备不会期待FD符号被配置成同时发送上行数据和接收下行数据。对于不同用户设备(如第一用户设备和第二用户设备)，基站设备在第一用户设备对应的FD符号配置发送上行数据，在第二用户设备对应的FD符号(与第一用户设备对应的FD符号同一位置)配置接收下行数据，这样，基站设备可以在该FD符号同时发送上行数据和接收下行数据。
对于不支持FD模式的用户设备，在DL数据和UL数据的转换过程时，可以预留出足够的GP资源供用户设备进行上下行切换。
对于支持FD模式的用户设备，FD符号可以被配置成同时发送上行数据和接收 下行数据，即用户设备同时发送上行数据和接收下行数据，不预留GP资源。
一个例子中，在TDD系统中通过TDD-UL-DL-ConfigCommon和TDD-UL-DL-ConfigDedicated确定帧结构，TDD-UL-DL-ConfigCommon用于配置服务小区范围内所有用户设备的帧结构，而对于一个或多个用户设备，通过TDD-UL-DL-ConfigDedicated来改变TDD-UL-DL-ConfigCommon中配置为F的符号，将其配置成UL或DL，以满足业务需求。在FD模式帧结构配置中，可以采用TDD-UL-DL-ConfigCommon和TDD-UL-DL-ConfigDedicated结合来完成。
在此基础上，在目标帧结构对应的多个时隙的符号中包括F符号(F符号可以作为DL、UL、或者GP，但是还没有用于DL、UL、或者GP)时，基站设备还可以向用户设备发送TDD-UL-DL-ConfigDedicated(上下行专用配置消息)，该上下行专用配置消息包括全双工参数，且全双工参数用于指示将F符号用于FD。用户设备可以从基站设备接收上下行专用配置消息，在上下行专用配置消息包括全双工参数时，用户设备期待F符号用于FD。
比如说，可以在服务小区配置参数ServingCellConfig中，引入一个新的参数，如TDD-UL-DL-ConfigDedicated-FullDuplex参数，并在这个新的参数中引入TDD-UL-DL-SlotConfig-FullDuplex参数用于配置F符号。其中，帧结构的配置参数TDD-UL-DL-SlotConfig-FullDuplex的伪码如下所示：
Figure PCTCN2022090609-appb-000004
Figure PCTCN2022090609-appb-000005
其中，在上述代码中，allFullDuplex表示当前时隙中的所有符号均被配置成FD符号，enableOtherSymbolsFullDuplex如果配置，则表示除DL符号和UL符号之外的其它符号可以做为FD符号使用，FD符号同时可以作为GP用于用户设备的上下行切换。如果服务小区中未配置TDD-UL-DL-Pattern-FullDuplex，则用户设备不会期待配置TDD-UL-DL-ConfigDedicated-FullDuplex。此外，如果在TDD-UL-DL-ConfigDedicated中配置FD符号，用户设备不会期待在同一个时隙中配置不连续的FD符号。对于HD模式的用户设备来说，用户设备不会期待相同的FD符号被基站设备同时配置成发送上行数据和接收下行数据。
由以上技术方案可见，可以将基站设备对应的工作模式区分为使能FD模式和关闭FD模式，在工作模式是使能FD模式时，允许时隙中的符号作为FD符号，即将时隙中的符号的功能扩展到作为FD符号，而在时隙中的符号作为FD符号时，基站设备和用户设备可以在FD符号对应的时域资源同时处理上行数据和下行数据，这样，相同时域资源能够同时处理上行数据和下行数据，从而更加有效的利用时域资源，提高资源利用率，能够提高网络覆盖和网络容量，同时降低传输时延，如降低上行传输时延。在不影响当前5G系统的情况下，配置固定FD符号的帧结构，完成帧结构的配置后，基 站设备和用户设备就可以根据帧结构的类型进行数据的发送和接收，基站设备和FD模式的用户设备可以同时进行收发，HD模式的用户设备同一时刻只能进行发送或者接收，能够实现灵活的FD符号配置。
基于同一发明构思，还提供了与上述TDD帧结构配置方法对应的TDD帧结构配置装置，及基站设备和用户设备，由于基站设备和用户设备解决问题的原理与上述例子的TDD帧结构配置方法相似，因此，基站设备和用户设备的实施可以参见方法的实施，重复之处不再赘述。
