Description

转发器的配置方法及装置 技术领域
本申请涉及通信领域。
背景技术
与传统的2G(第二代移动通信技术)、3G(第三代移动通信技术)、4G(第四代移动通信技术)系统相比，5G(第五代移动通信技术)系统能够提供更大的带宽以及更高的数据率，并且能够支持更多类型的终端和垂直业务。为此，5G系统支持的频带范围/工作带宽明显大于2G，3G和4G系统，并且,5G系统支持更高的载波频率。例如，5G系统可以部署在毫米波波段。
然而，载波频率越高，信号在传输过程中遇到的衰落越严重。因此，在5G系统的实际部署中，特别是在毫米波段，如何更好的增强小区覆盖，成为亟待解决的问题。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
为了更好的解决蜂窝移动通信系统在实际部署中的覆盖问题，采用射频转发器(RF Repeater)放大和转发设备之间的信号，是比较常用的部署手段。射频转发器在2G系统、3G系统和4G系统的实际部署中具有较为广泛的应用，其优点在于低成本，易部署，且不会增加过多时延。通常来说，传统的射频转发器是一种在射频域放大(amplify)和转发(forward)设备往来信号的设备。也就是说，传统的射频转发器是一种非再生类型的中继节点，射频转发器只是将接收到的所有信号直接放大并转发。
在R-17的终端设备的上行/下行时分双工(UL/DL TDD)配置中，在下行与上行区域之间会配置灵活区域，除了使终端设备可以为一些突发的传输灵活的利用该区域的时域资源之外，还可以为终端设备在下行区域接收数据之后和上行区域发送数据之前提供一段缓冲时间，使终端设备有足够的时间处理接收到的数据并为发送数据做准 备。
在R-17的UL/DL TDD配置中，半静态配置的小区公共灵活区域可以被终端设备的专属配置进行修改，即根据终端设备的专属配置在灵活区域上进行收发。终端设备的动态UL/DL TDD配置可以修改半静态配置的灵活区域。当终端设备在灵活区域上没有动态配置时，该终端设备根据搜索空间配置在对应的控制资源集(CORESET)上检测的物理下行控制信道(PDCCH)，并根据PDCCH的指示在灵活区域上确定收发方向，该终端设备在检测到对应的调度指示前不在灵活区域进行信道和信号的接收和发送。
在R-17中，为了增强网络设备(例如基站)的覆盖，提出射频转发器(RF repeater)为终端设备和网络设备之间的通信进行放大和转发。对于射频转发器的转发的现有技术是通过实现的方式解决的。
发明人发现，在现有技术中，并未对转发器用于转发的TDD配置提出相应的解决方案，并且在用于转发的TDD配置的灵活区域中，针对转发器该如何确定转发行为以及相关的配置方式也没有解决方案，导致转发器无法灵活的利用灵活区域。
另外，转发器与网络设备之间能够进行通信(又称为传输)，现有技术中并没有考虑转发器在配置的灵活区域中传输与转发的配置关系，也没有针对转发器在配置的灵活区域中如何确定传输与转发的行为的解决方案，导致转发器的转发与传输在灵活区域内容易产生冲突。
为了解决上述问题中的一个或多个，本申请实施例提供一种转发器的配置方法及装置。即，针对上述问题中的一个或多个，本申请实施例提出了相应的解决方案。
根据本申请实施例的第一方面，提供一种转发器的配置装置，所述装置设置于转发器，所述装置包括：第一接收单元，其接收来自网络设备的时分双工(TDD)配置信息；以及第一确定单元，其确定在第一灵活时间单元上的转发行为。
根据本申请实施例的第二方面，提供一种转发器的配置装置，所述装置设置于网络设备，所述装置包括：第一发送单元，其向转发器发送时分双工(TDD)配置信息。
根据本申请实施例的第三方面，提供一种转发器，所述转发器包括根据本申请实施例的第一方面所述的装置。
根据本申请实施例的第四方面，提供一种网络设备，所述网络设备包括根据本申请实施例的第二方面所述的装置。
根据本申请实施例的第五方面，提供一种通信系统，所述通信系统包括根据本申请实施例的第三方面所述的转发器和/或根据本申请实施例的第四方面所述的网络设备，以及终端设备。
根据本申请实施例的第六方面，提供一种转发器的配置方法，所述方法包括：转发器接收来自网络设备的时分双工(TDD)配置信息；以及转发器确定在第一灵活时间单元上的转发行为。
根据本申请实施例的第七方面，提供一种转发器的配置方法，所述方法包括：网络设备向转发器发送时分双工(TDD)配置信息。
根据本申请实施例的第八方面，提供了一种计算机可读程序，其中当在转发器的配置装置或转发器中执行所述程序时，所述程序使得所述转发器的配置装置或转发器执行本申请实施例的第六方面所述的转发器的配置方法。
根据本申请实施例的第九方面，提供了一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得转发器的配置装置或转发器执行本申请实施例的第六方面所述的转发器的配置方法。
根据本申请实施例的第十方面，提供了一种计算机可读程序，其中当在转发器的配置装置或网络设备中执行所述程序时，所述程序使得所述转发器的配置装置或网络设备执行本申请实施例的第七方面所述的转发器的配置方法。
根据本申请实施例的第十一方面，提供了一种存储有计算机可读程序的存储介质，其中所述计算机可读程序使得转发器的配置装置或网络设备执行本申请实施例的第七方面所述的转发器的配置方法。
本申请实施例的有益效果之一在于：
通过向转发器发送TDD配置信息，转发器能够确定配置的灵活区域，并且，转发器确定第一灵活时间单元上的转发行为，使转发器的转发对于突发的业务传输更加灵活，并且使转发器在下行转发与上行转发之间具有一段缓冲时间，从而使转发器有足够的时间处理接收到的数据并为发送业务做准备。
另外，还考虑了转发器在配置的灵活区域中传输与转发的配置关系，避免转发器的转发与传输在灵活区域内发生冲突，保证转发器的转发与传输的可靠性。

步骤301：转发器接收来自网络设备的时分双工(TDD)配置信息；以及
步骤302：转发器确定在第一灵活时间单元上的转发行为。
这样，通过向转发器发送TDD配置信息，转发器能够确定配置的灵活区域，并且，转发器确定在第一灵活时间单元上的转发行为，使转发器的转发对于突发的业务传输更加灵活，并且使转发器在下行转发与上行转发之间具有一段缓冲时间，从而使转发器有足够的时间处理接收到的数据并为发送业务做准备。
在步骤301中，转发器接收来自网络设备的时分双工配置信息，例如，转发器通过图1和图2中的下行通信链路接收时分双工配置配置信息。
在一些实施例中，该时分双工配置又称为上行/下行时分双工(UL/DL TDD)配置。
在一些实施例中，该时分双工配置信息配置的时域资源包括以下时间单元中的至少一个：下行时间单元、灵活时间单元以及上行时间单元。

该上行转发包括转发终端设备向网络设备传输的信道和/或信号；该下行转发包括转发网络设备向终端设备传输的信道和/或信号。
另外，关于转发器如何确定在灵活时间单元上的转发行为，将在下面进行具体的描述。

在一些实施例中，该半静态时分双工配置由RRC信令、MAC层信令以及物理层信令中的至少一个来指示。也就是说，通过半静态信令来指示该半静态时分双工配置。

在一些实施例中，该半静态时分双工配置包括小区公共(cell-common)时分双工配置和/或转发器专属(repeater-dedicated)时分双工配置。
也就是说，该半静态时分双工配置可以包括小区公共时分双工配置，或者，包括转发器专属时分双工配置，或者，包括小区公共时分双工配置和转发器专属时分双工配置。
在一些实施例中，对于小区公共时分双工配置，例如通过半静态的小区公共信令来指示，对于转发器专属时分双工配置，例如通过半静态的针对转发器专属的信令来指示。

在一些实施例中，在上述信令中可以指示灵活时隙和/或符号个数，也可以不指示灵活时隙和/或符号个数。在不指示灵活时隙和/或符号个数的情况下，可以认为在上述周期内除了上行时间单元和下行时间单元的其他时间单元为灵活时隙和/或符号，其中，灵活时隙和/或符号是灵活时间单元的时隙和/或符号。
在一些实施例中，在配置了第一模式时，每20ms/P个周期的第一个符号与偶数帧的第一个符号对齐，或者，每20ms/P个周期的第一个符号是偶数帧的第一个符号，其中，P能被20整除，20ms表示两个帧长，即每个帧长为10ms。

在一些实施例中，在配置了第一模式(pattern 1)和第二模式(pattern 2)时，每20ms/(P+P 2)个周期的第一个符号与偶数帧的第一个符号对齐，或者，每20ms/(P+P 2)个周期的第一个符号是偶数帧的第一个符号，其中，P+P 2能被20整除，20ms表示两个帧长，即每个帧长为10ms。
在一些实施例中，该转发器专属时分双工配置仅在该小区公共时分双工配置的灵活区域单元上进行配置。例如，只能在小区公共上下行TDD配置的灵活区域进行设备专用上下行的配置；即，只能改变小区公共上下行TDD配置的灵活区域，不能改变小区公共上下行TDD配置的上下行区域。
在一些实施例中，该转发器专属时分双工配置由RRC信令、MAC层信令以及物理层信令中的至少一个来指示。

又例如，如果未配置下行符号数，则该时隙内没有下行符号；如果未配置上行符号数，则该时隙内没有上行符号；配置上行符号和/或下行符号数后，该时隙内剩余符号为灵活符号。
其中，所述时隙为上述信令指示在周期中的时隙位置对应的时隙。
以上针对半静态时分双工配置进行了说明，下面针对动态时分双工配置进行说明。
在一些实施例中，该动态时分双工配置由RRC信令、MAC层信令以及物理层信令中的至少一个来指示。
例如，该动态时分双工配置由物理层信令指示。例如采用DCI format 2_0，来动态的指示某一时隙的format配置。
在一些实施例中，该动态时分双工配置能够对半静态时分双工配置中的灵活时间单元进行配置。例如，可以对半静态时分双工配置的灵活时间单元指示相应的时隙格式(slot format)，从而进行动态配置，但是不能修改半静态时分双工配置中的上行时间单元和下行时间单元。
在一些实施例中，可以由RRC信令、MAC信令以及物理层信令中的至少一个信令来指示该动态时分双工配置应用的小区标识和/或该动态时分双工配置对应的时隙格式索引(SFI，slot format indicator)和/或该动态配置应用的时隙格式。

在一些实施例中，指示SFI的配置对半静态配置的信号和/或信道传输没有影响的格式可称为255格式，该格式不能修改灵活区域。
在一些实施例中，当重叠的常规循环前缀(normal CP)符号中的一个是灵活的时，该转发器将扩展循环前缀(extended CP)符号确定为该灵活时间单元上的灵活符号；和/或，当重叠的一对常规循环前缀符号包括一个下行符号和一个上行符号时，该转发器将该扩展循环前缀符号确定为该灵活时间单元上的灵活符号。
在一些实施例中，“重叠的常规循环前缀”是指与扩展循环前缀重叠的常规循环前缀。
在步骤301中，转发器接收来自网络设备的时分双工(TDD)配置信息，因此转发器能够确定时分双工配置中的灵活时间单元，进一步的，在步骤302中，转发器确定在第一灵活时间单元上的转发行为。
在一些实施例中，该第一灵活时间单元包括时分双工配置中的灵活时间单元的至少一部分。
例如，该第一灵活时间单元是基于时分双工配置中的灵活时间单元而确定的。但是，本申请实施例不限于此。
例如，该第一灵活时间单元包括时分双工配置中的灵活时间单元的一部分，或者，该第一灵活时间单元包括该灵活时间单元的全部，或者，该第一灵活时间单元包括该灵活时间单元的一部分以及其他时域资源，或者，该第一灵活时间单元包括该灵活时间单元的全部以及其他时域资源。
在一些实施例中，该转发行为包括上行转发、下行转发以及不进行转发中的至少一个。
在一些实施例中，该上行转发包括转发终端设备向网络设备传输的信道和/或信号；该下行转发包括转发网络设备向终端设备传输的信道和/或信号。
在一些实施例中，转发器确定在第一灵活时间单元上的转发行为，可以是该转发 器根据第一指示，确定在该第一灵活时间单元上的转发行为；或者，也可以是该转发器根据默认的第一规则，确定在该第一灵活时间单元上的转发行为。
也就是说，转发器可以通过指示或默认的方式来确定在该第一灵活时间单元上的转发行为。
图5是本申请实施例1的转发器确定在第一灵活时间单元上的转发行为的方法的一示意图。如图5所示，该方法包括：
步骤501：转发器根据第一指示，确定在该第一灵活时间单元上的转发行为；或者，
步骤502：转发器根据默认的第一规则，确定在该第一灵活时间单元上的转发行为。
在一些实施例中，“默认的规则”是指，预定义的规则或规定，例如协议中的规定。
首先针对通过指示的方式进行说明。
在一些实施例中，该第一指示通过物理层信令、MAC层信令以及RRC信令中至少一个来配置。例如，该第一指示通过物理层信令来配置，例如DCI format。
在一些实施例中，当转发器收到第一指示时，该转发器确定在该第一灵活时间单元上进行上行转发和/或下行转发。
例如，当转发器收到第一指示时，该转发器根据以下方式确定在该第一灵活时间单元上的转发行为：
当该转发器收到指示上行转发的该第一指示时，该转发器确定在该第一灵活时间单元上将终端设备发送的信道和/或信号转发给网络设备；和/或，
当该转发器收到指示下行转发的该第一指示时，该转发器确定在该第一灵活时间单元上将网络设备发送的信道和/或信号转发给终端设备。
又例如，当该转发器没有收到该第一指示时，该转发器根据默认的第二规则确定在该第一灵活时间单元上的转发行为，该第二规则包括以下规则中的一种：
该转发器在该第一灵活时间单元的部分符号或所有符号只做下行转发；
该转发器在该第一灵活时间单元的部分符号或所有符号只做上行转发；
该转发器在该第一灵活时间单元的前n1个符号进行下行转发，后n2个符号进行上行转发，且n1+n2不大于该第一灵活时间单元的符号总数；以及
该转发器在该第一灵活时间单元上不进行任何转发。
在一些实施例中，默认的第一规则可以和第二规则相同。
例如，该第一规则包括以下规则中的一种规则：
该转发器在该第一灵活时间单元的部分符号或所有符号只做下行转发；
该转发器在该第一灵活时间单元的部分符号或所有符号只做上行转发；
该转发器在该第一灵活时间单元的前n1个符号进行下行转发，后n2个符号进行上行转发，且n1+n2不大于该第一灵活时间单元的符号总数；以及
该转发器在该第一灵活时间单元上不进行任何转发。
在一些实施例中，默认的第一规则也可以和第二规则不同。
在一些实施例中，在转发器确定在第一灵活时间单元上进行上行转发和/或下行转发的情况下，如图3所示，该方法还包括：
步骤303：转发器在第一灵活时间单元上进行上行转发和/或下行转发。
在一些实施例中，转发器确定在该第一灵活时间单元上的转发行为时，还可以考虑转发器接收的第一指示与转发器服务的终端设备接收的第二指示所指示的传输方向的一致性。
在一些实施例中，该转发器根据接收的第一指示所指示的在该第一灵活时间单元上的转发方向与该转发器服务的终端设备接收的第二指示所指示的在第二灵活时间单元上的传输方向是否一致，来确定该转发器在第一灵活时间单元上的转发行为。
例如，当该转发器根据接收的第一指示所指示的在该第一灵活时间单元上的转发方向与该转发器服务的终端设备接收的第二指示所指示的在该第二灵活时间单元上的传输方向一致时，该转发器在第一灵活时间单元上进行上行转发或下行转发；
当该转发器根据接收的第一指示所指示的在该第一灵活时间单元上的转发方向与该转发器服务的终端设备接收的第二指示所指示的在该第二灵活时间单元上的传输方向不一致时，该转发器在第一灵活时间单元上不进行转发。
在一些实施例中，第二灵活时间单元是由该终端设备的时分双工配置确定的，另外，第一灵活时间单元和第二灵活时间单元在时域上是相同的，即是相同的时域资源。
在一些实施例中，“一致”例如是指，转发器在第一灵活时间单元上进行下行转发与该终端设备在第二灵活时间单元上进行接收是一致的，和/或，转发器在第一灵活时间单元上进行上行转发与该终端设备在第二灵活时间单元上进行发送是一致的。
在一些实施例中，“不一致”例如是指，转发器在第一灵活时间单元上进行下行转发与该终端设备在第二灵活时间单元上进行发送是不一致的，和/或，转发器在第一灵活时间单元上进行上行转发与该终端设备在第二灵活时间单元上进行接收是不一致的。
以下通过具体的示例进行说明。
当转发器接收到或检测到指示转发器在一组灵活符号进行下行转发信道或信号的第一指示时，例如，
当转发器接收或检测到指示转发器在这组符号上接收PDSCH或CSI-RS的一个DCI fromat，且转发器所服务的终端设备接收或检测到指示该终端设备在这组符号上接收PDSCH或CSI-RS的一个DCI fromat时，转发器将从网络设备接收的PDSCH或CSI-RS发送给与该转发器对应的终端设备；和/或，
当转发器接收或检测到指示转发器在这组符号上接收PDSCH或CSI-RS的一个DCI fromat，并且，转发器所服务的终端设备没有接收或检测到指示该终端设备在这组符号上接收PDSCH或CSI-RS的一个DCI fromat或者转发器所服务的终端设备接收或检测到指示该终端设备在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI format或RAR UL grant或fallbackRAR UL grant或successRAR时，则转发器不在这组符号上进行下行转发。
当转发器接收到或检测到指示转发器在一组灵活符号进行上行转发信道或信号的第一指示时，例如，
当转发器接收或检测到指示转发器在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR，且转发器所服务的终端设备接收或检测到指示该终端设备在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR时，转发器将从终端设备接收的PPUSCH或PUCCH或PRACH或SRS发送给网络设备；和/或，
当转发器接收或检测到指示转发器在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR，并且，转发器所服务的终端设备没有接收或检测到指示该终端设备在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant 或fallbackRAR UL grant或successRAR或者转发器所服务的终端设备接收或检测到指示该终端设备在这组符号上接收PDSCH或CSI-RS的一个DCI format时，转发器不在这组符号上进行上行转发。
在一些实施例中，对于由该小区公共时分双工配置指示的灵活区域单元中的符号，当配置了该转发器专属时分双工配置时，该转发器不希望同时收到配置为发送的转发器专属时分双工配置信令和配置为接收的转发器专属时分双工配置信令，以避免冲突。
如前所述，转发器被的时分双工配置包括半静态时分双工配置和/或动态时分双工配置。
在一些实施例中，对于转发器被配置该半静态时分双工配置的情况，
当该转发器没有被配置检测该动态时分双工配置，并且被该小区公共时分双工配置和该转发器专属时分双工配置的一个时隙的一组符号是灵活的时；或者，当该转发器没有被提供该小区公共时分双工配置和该转发器专属时分双工配置时，该转发器接收到上行转发的相关指示时，该转发器进行上行转发；和/或，该转发器接收到下行转发的相关指示时，该转发器进行下行转发。
例如，当转发器没有被配置去检测动态时分双工配置，例如承载DCI format 2_0的PDCCH，并且，一个时隙中的符号被提供的小区公共时分双工配置和该转发器专属时分双工配置指示是灵活的，或者当转发器没有被提供半静态公共配置和专属配置时，
如果转发器接收或检测到一个DCI format的相应指示，转发器接收PDSCH或CSI-RS，或者转发器将从终端设备接收的PDSCH或CSI-RS发送给对应的终端设备；
如果转发器接收或检测到一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR的相应指示，转发器发送PUSCH或PUCCH或PRACH或SRS，或者转发器将从终端设备接收的PUSCH或PUCCH或PRACH或SRS发送给终端设备。
在一些实施例中，对于转发器被配置动态时分双工配置的情况，
当该转发器被该小区公共时分双工配置和该转发器专属时分双工配置的一个时隙的一组符号被指示是灵活的时，或者，当该转发器没有被提供该小区公共时分双工配置和该转发器专属时分双工配置，并且检测到该动态时分双工配置提供的时隙格式 且不是255格式时，
该转发器接收或检测到指示该转发器在该时隙的该符号上进行上行转发或者下行转发的第一指示的情况下，该转发器在该时隙的该符号上进行上行转发或者下行转发；和/或，
该转发器没有接收或检测到指示该转发器在该时隙的该符号上进行上行转发的第一指示或者指示该转发器在时隙的符号上进行下行转发的第一指示的情况下，该转发器不在该时隙的该符号上进行上行转发或者下行转发。
例如，当指示给转发器的一个时隙中的一组符号被提供的小区公共时分双工配置和转发器专属时分双工配置指示是灵活的，或者，转发器没有被提供小区公共时分双工配置和转发器专属时分双工配置，并且转发器检测到动态TDD配置，例如DCI format 2_0利用时隙格式值提供的一个时隙的格式且不是255时，
如果这组符号中的一个或多个符号是CORESET中的符号，被配置给转发器进行PDCCH监听的，那么只有当DCI format 2_0中的SFI-index值指示这一个或多个符号是下行符号时，转发器接收CORESET中的PDCCH，或者转发器将从网络设备接收的CORESET中的PDCCH发送给与该转发器对应的终端设备；
如果DCI format 2_0中的SFI-index值指示这组符号是灵活的，并且转发器接收或检测到指示转发器在这组符号上接收PDSCH或CSI-RS的一个DCI fromat时，转发器接收PDSCH或CSI-RS，或者转发器将从网络设备接收的PDSCH或CSI-RS发送给与该转发器对应的终端设备；
如果DCI format 2_0中的SFI-index值指示这组符号是灵活的，并且转发器接收或检测到指示转发器在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR时，转发器发送PUSCH或PUCCH或PRACH或SRS，或者转发器将从终端设备接收的PUSCH或PUCCH或PRACH或SRS发送给网络设备；
如果DCI format 2_0中的SFI-index值指示这组符号是灵活的，并且，转发器没有接收或检测到指示转发器在这组符号上接收PDSCH或CSI-RS的一个DCI fromat或者没有接收或检测到指示转发器在这组符号上发送PUSCH或PUCCH或PRACH或SRS的一个DCI fromat或RAR UL grant或fallbackRAR UL grant或successRAR时，转发器不在这组符号上发送或接收，或者转发器不在这组符号上进行上行转发或下行 转发。
在一些实施例中，对于转发器被配置该动态时分双工配置的情况，还可以包括：
当该转发器被该小区公共时分双工配置和该转发器专属时分双工配置的一个时隙的一组符号被指示是灵活的时，或者，当该转发器没有被提供该小区公共时分双工配置和该转发器专属时分双工配置且没有该动态时分双工配置提供时隙格式时，在该转发器接收到第一指示的情况下，该转发器在该时隙的该符号上做上行转发或者下行转发。
如前所述，本申请实施例的转发器除了能够转发之外，还能够与网络设备进行通信(又称为传输)，例如，通过下行通信链路和/或上行通信链路与网络设备进行通信。
在一些实施例中，需要考虑转发器用于通信(传输)的时分双工配置与转发器用于转发的时分双工配置之间的关系，例如，需要考虑转发器在配置的灵活区域中通信(传输)与转发的配置关系，从而，能够避免转发器的转发与传输在灵活区域内发生冲突，保证转发器的转发与传输的可靠性。
在步骤301中，转发器接收来自网络设备的时分双工配置信息，在一些实施例中，该时分双工配置信息指示该转发器用于转发的下行时间单元、灵活时间单元以及上行时间单元中的至少一个，和/或，指示该转发器用于通信的下行时间单元、灵活时间单元以及上行时间单元中的至少一个。
在一些实施例中，可以使用同一个时分双工配置信息来指示该转发器用于转发和用于传输的下行时间单元、灵活时间单元以及上行时间单元中的至少一个，也可以使用不同的双工配置信息来分别指示该转发器用于转发和用于传输的下行时间单元、灵活时间单元以及上行时间单元中的至少一个。
例如，该时分双工配置信息指示该转发器用于转发的下行时间单元、灵活时间单元以及上行时间单元中的至少一个，并且，该时分双工配置信息还指示该转发器用于通信的下行时间单元、灵活时间单元以及上行时间单元中的至少一个；
又例如，该转发器分别接收第一时分双工配置信息和第二时分双工配置信息，其中，该第一时分双工配置信指示该转发器用于转发的下行时间单元、灵活时间单元以及上行时间单元中的至少一个，该第二时分双工配置信息指示该转发器用于通信的下行时间单元、灵活时间单元以及上行时间单元中的至少一个。
在一些实施例中，用于转发的时分双工配置信息重用(采用)用于通信的时分双 工配置信息，或者用于转发的时分双工配置信息与用于通信的时分双工配置信息是相同的；或者，也可以不重用(不采用)用于通信的时分双工配置信息，或者用于转发的时分双工配置信息与用于通信的时分双工配置信息是不同的。
例如，用于转发的时分双工配置信息所配置的参数是“aaabbbxxx”，但是，“aaabbbxxx”实际上就是与用于通信的参数相同的参数，或者转发器用于转发的时分双工配置的参数采用转发器用于通信的时分双工配置的参数“aaabbbxxx”。
另外，“aaabbbxxx”只是对于参数形式的一个示例，其不是对参数形式和/或内容的限制。
又例如，转发器的转发根据一个信令确定reference SCS，而该信令实际上就是转发器的用于通信的信令。
以下对转发器用于通信(传输)的时分双工配置与转发器用于转发的时分双工配置之间的关系进行具体的说明。
在一些实施例中，转发器接收时分双工配置，指示转发器用于转发的下行转发时间单元、上行转发时间单元以及灵活时间单元，转发器接收的该时分双工配置采用指示转发器用于通信的时分双工配置，或者转发器接收的该时分双工配置与指示转发器用于通信的时分双工配置是相同的。
例如，转发器接收或检测的指示在上述灵活时间单元中转发行为的指示信令采用转发器接收或检测的指示在上述灵活时间单元中通信行为的指示信令，或者转发器接收或检测的指示在上述灵活时间单元中转发行为的指示信令与转发器接收或检测的指示在上述灵活时间单元中通信行为的指示信令是相同的；
又例如，转发器接收或检测的指示在上述灵活时间单元中转发行为的指示信令不采用转发器接收或检测的指示在上述灵活时间单元中通信行为的指示信令，或者转发器接收或检测的指示在上述灵活时间单元中转发行为的指示信令与转发器接收或检测的指示在上述灵活时间单元中通信行为的指示信令是不同的。
在一些实施例中，转发器接收时分双工配置，指示转发器用于转发的下行转发时间单元、上行转发时间单元以及灵活时间单元，转发器接收的该时分双工配置不采用指示转发器用于通信的时分双工配置，或者转发器接收的该时分双工配置与指示转发器用于通信的时分双工配置是不同的。
例如，转发器接收的用于转发的时分双工配置信令不采用转发器通信的时分双工 配置信令，或者用于转发的时分双工配置信令与转发器用于通信的时分双工配置信令是不同的；而转发器接收的用于转发的时分双工配置的参数采用转发器用于通信的时分双工配置的参数，或者用于转发的时分双工配置的参数与转发器用于通信的时分双工配置的参数是相同的；
其中，例如转发器接收或检测的指示在上述灵活时间单元中转发行为的指示采用转发器接收或检测的指示在上述灵活时间单元中通信行为的指示，或者转发器接收或检测的指示在上述灵活时间单元中转发行为的指示与转发器接收或检测的指示在上述灵活时间单元中通信行为的指示是相同的，例如，转发器接收或检测的指示在第一灵活时间单元中的转发行为的指示和通信行为的指示是相同的DCI fromat。
又例如，转发器接收的用于转发的时分双工配置信令不采用转发器用于通信的时分双工配置信令，或者用于转发的时分双工配置信令与转发器用于通信的时分双工配置信令是不同的；而转发器接收的用于转发的时分双工配置的参数不采用转发器用于通信的时分双工配置的参数，或者用于转发的时分双工配置的参数与转发器用于通信的时分双工配置的参数是不同的；
其中，例如转发器接收或检测的指示在上述灵活时间单元中转发行为的指示不采用转发器接收或检测的指示在上述灵活时间单元中通信行为的指示，或者转发器接收或检测的指示在上述灵活时间单元中的转发行为的指示与转发器接收或检测的指示在上述灵活时间单元中的通信行为的指示是不同的，例如，转发器接收或检测的指示在第一灵活时间单元中的转发行为的指示和通信行为的指示是不同的DCI fromat。
在一些实施例中，转发器接收的用于转发的时分双工配置的参数采用转发器用于通信的时分双工配置的参数，或者转发器用于转发的时分双工配置的参数与用于通信的时分双工配置的参数是相同的；
在一些实施例中，转发器接收的用于转发的时分双工配置的参数不采用转发器用于通信的时分双工配置的参数，或者转发器用于转发的时分双工配置的参数与通信的时分双工配置的参数是不同的。
在一些实施例中，在需要考虑转发器的转发与通信(传输)这两种行为的情况下，在步骤302中，转发器确定在第一灵活时间单元上的转发行为和/或通信行为。
在一些实施例中，该通信行为包括该转发器与网络设备间的上行传输、下行传输以及不进行传输中的至少一个。
例如，该上行传输包括转发器向网络设备发送信道和/或信号；该下行传输包括该转发器从该网络设备接收信道和/或信号。
在一些实施例中，该下行传输包括检测序列、解调、解扰、解码以及解读信息等处理中的至少一个；该上行传输包括生成信息、生成序列、加扰、编码、调制、映射到时频资源等处理中的至少一个。
在一些实施例中，该转发器根据默认的第三规则确定在第一灵活时间单元上的转发行为和/或通信行为。例如，该转发器根据默认的第三规则确定在第一灵活时间单元上是否进行转发和/或通信。
如前所述，“默认的规则”是指，预定义的规则或规定，例如协议中的规定。
在一些实施例中，该第三规则包括以下规则中的一种：
在该第一灵活时间单元上，该转发器进行通信(传输)但不进行转发；
在该第一灵活时间单元上，该转发器进行转发但不进行通信(传输)；
在该第一灵活时间单元上，该转发器进行通信(传输)和转发；以及
在该第一灵活时间单元上，该转发器不进行通信(传输)和转发。
在一些实施例中，当在第一灵活时间单元上可以进行转发而不可以进行通信时，转发器接收第一信令，该第一信令指示转发器根据指示进行转发还是根据默认配置(例如，与前述的第一规则的配置方式相同)进行转发。
例如，采用1比特(bit)指示，即，第一信令指示1时根据默认配置进行转发，指示为0时根据指示确定转发方向。
又例如，采用第一信令指示默认配置被采用，当第一信令被提供时，转发器根据默认配置确定第一灵活时间单元上的转发方向；当第一信令没有被提供时，转发器根据指示确定第一灵活时间单元上的转发方向。
在一些实施例中，当在第一灵活时间单元中可以进行通信不可以进行转发时，转发器接收第二信令，该第二信令指示转发器根据指示进行通信还是根据默认配置进行通信。
例如，采用1bit指示，第二信令指示1时根据默认配置进行通信，指示为0时根据指示确定通信方向(传输方向)。
又例如，采用第二信令指示默认配置被采用，当第二信令被提供时，转发器根据默认配置确定第一灵活时间单元上的通信方向(传输方向)；当第二信令没有被提供 时，转发器根据指示确定第一灵活时间单元上的通信方向(传输方向)。
在一些实施例中，在第一灵活时间单元中可以进行转发也可以进行通信时，转发器接收第一信令和/或第二信令，第一信令指示转发器根据指示进行转发还是根据默认配置进行转发，第二信令指示转发器根据指示进行通信(传输)还是根据默认配置进行通信。
例如采，用1bit指示，第一信令/第二信令指示1时根据默认配置进行转发和/或通信(传输)，指示为0时根据指示确定转发方向和/或通信方向(传输方向)。
例如，采用第一信令和/或第二信令指示默认配置被采用，当第一信令和/或第二信令被提供时，转发器根据默认配置确定第一灵活时间单元的转发方向和/或通信方向(传输方向)；当第一信令和/或第二信令没有被提供时，转发器根据指示确定第一灵活时间单元的转发方向和/或通信方向(传输方向)。
在一些实施例中，该转发器也可以根据转发优先级和通信优先级确定在第一灵活时间单元上的转发行为和/或通信行为。
在一些实施例中，该转发优先级基于该转发器服务的终端设备的优先级和/或该转发器转发的业务的优先级确定。
例如，当该转发优先级高于该通信优先级时，该转发器确定在该第一灵活时间单元上只进行转发，不进行通信；或者，该转发器确定先在该第一灵活时间单元中确定转发时间区域，再在该第一灵活时间单元的剩余区域中确定通信时间区域。
又例如，当该通信优先级高于该转发优先级时，该转发器确定在该第一灵活时间单元上只进行通信，不进行转发；或者，该转发器确定先在该第一灵活时间单元中确定通信时间区域，再在该第一灵活时间单元的剩余区域中确定转发时间区域。
在一些实施例中，优先级高是指优先级程度高，优先级低是指优先级程度低。
例如，优先级的数值越小，优先级(的程度)越高，优先级的数值越大，优先级(的程度)越低；
又例如，也可以是优先级的数值越大，优先级(的程度)越高，优先级的数值越小，优先级(的程度)越低。
在一些实施例中，转发器能够确定转发器所服务的终端设备的优先级；
在一些实施例中，转发器在进行转发时，也可以确定转发的业务的优先级。
由上述实施例可知，通过向转发器发送TDD配置信息，转发器能够确定配置的 灵活区域，并且，转发器确定在第一灵活时间单元上的转发行为，使转发器的转发对于突发的业务传输更加灵活，并且使转发器在下行转发与上行转发之间具有一段缓冲时间，从而使转发器有足够的时间处理接收到的数据并为发送业务做准备。
另外，还考虑了转发器在配置的灵活区域中传输与转发的配置关系，避免转发器的转发与传输在灵活区域内发生冲突，保证转发器的转发与传输的可靠性。
实施例2
本申请实施例2还提供一种转发器的配置方法，该方法应用于网络设备侧。该方法对应于实施例1中的转发器侧的转发器的配置方法，相同的内容不再重复说明。例如，该方法应用于图1和图2中的网络设备101。
图6是本申请实施例2的转发器的配置方法的一示意图。如图6所示，该方法包括：
步骤601：网络设备向转发器发送时分双工(TDD)配置信息。

由上述实施例可知，通过向转发器发送TDD配置信息，转发器能够确定配置的灵活区域，并且，转发器确定在第一灵活时间单元上的转发行为，使转发器的转发对于突发的业务传输更加灵活，并且使转发器在下行转发与上行转发之间具有一段缓冲时间，从而使转发器有足够的时间处理接收到的数据并为发送业务做准备。
实施例3
本申请实施例3提供了一种转发器的配置装置，该装置设置于转发器。由于该装置解决问题的原理与实施例1的方法类似，因此其具体的实施可以参照实施例1所述的方法的实施，内容相同或相关之处不再重复说明。
