Description

转发器接入链路的转发方法及装置 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Rel-17 3GPP研究中提出的RF repeater能够转发基站与终端之间的传输从而增强5G系统的网络覆盖。然而RF repeater对于基站和终端是透明的并且不受基站的控制，因此Rel-17中的RF repeater对其他设备造成干扰且不能控制其能耗，需要一直处于监听转发的状态。
在Rel-18的研究中，提出由网络控制的转发器(NCR，network-controlled repeater) 能够接收网络侧的控制信息(side control information)。NCR包括NCR-MT(也称为通信单元)和NCR-Fwd(也称为转发单元)，其中，NCR-MT能够与基站进行通信，并根据基站发送的控制信息对NCR-Fwd的转发进行控制，NCR-Fwd是组成NCR的实现基站与终端之间转发的部分，包括NCR与基站连接的回传链路(backhaul link，BH-link)以及终端侧的接入链路(access link，AC-link)。
为了使NCR能够更好的增强覆盖，更准确地转发基站与终端的通信，并减小对周围其他设备的干扰，基站控制并指示NCR-Fwd的回传链路波束和接入链路波束。目前，仅确定可以将波束标识(beam index)用于接入链路的波束管理。
发明人发现，在现有技术中，并没有如何确定波束标识以及如何使用波束标识进行接入链路的波束管理的具体方案，即，缺乏有效的接入链路的波束管理机制，导致无法确定NCR的接入链路的波束，从而无法有效利用波束标识并完成终端与基站之间的转发。
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接入链路的转发方法及装置。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，提供一种转发器接入链路的转发装置，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接入链路的波束标识；以及，转发单元，其使用接收的所述波束标识对应的波束进行转发。
根据本申请实施例的第二方面，提供一种转发器接入链路的波束标识的指示装置，所述装置设置于网络设备，所述装置包括：第一指示单元，其向转发器指示接入链路的波束标识。
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。

实施例1
本申请实施例提供一种转发器接入链路的转发方法，应用于转发器。例如，应用于图1和图2中的转发器103。
图3是本申请实施例1的转发器接入链路的转发方法的一示意图。如图3所示，该方法包括：
步骤301：转发器的接收单元接收来自网络设备的接入链路的波束标识；以及
步骤302：转发器的转发单元使用接收的该波束标识对应的波束进行转发。
这样，转发器根据从网络设备接收的接入链路的波束标识，使用与该波束标识对应的波束进行接入链路上的转发，使网络设备能够调度转发器用于转发的接入链路波束，并使转发器能够确定转发的接入链路波束，因此，能够有效利用波束标识并完成终端与网络设备之间的转发。
在一些实施例中，转发器为网络控制的转发器，即NCR。
在一些实施例中，转发器的接收单元是NCR-MT或NCR-MT的一部分；转发器的转发单元是NCR-Fwd。例如，可以参见图2中的相关结构。
在一些实施例中，波束标识(beam index)对接入链路(AC-link)的波束进行标号(也可以称为编号)，得到波束标识，并由网络设备指示转发器所转发的波束标识。
另外，波束标识也可以表述为波束索引或波束编号或波束标号等。

在一些实施例中，转发器接收的该波束标识通过RRC信令、MAC CE以及物理层信令中的至少一种指示。
该物理层信令例如是DCI，或者，也可以是其他物理层信令。
这样，通过物理层信令指示接入链路的波束标识，减小了波束标识指示的信令开销及传输的时延，从而提高系统的利用效率。
在一些实施例中，转发器接收的该波束标识是网络设备配置的接入链路的波束标识中的至少一个，也就是说，由网络设备确定接入链路的波束标识并向转发器指示确定的波束标识中的至少一个。
例如，网络设备配置的接入链路的波束标识为波束#1，波束#2，波束#3，……，当转发器需要在接入链路上进行转发时，网络设备向转发器指示的波束标识(即转发器接收的该波束标识)为该网络设备配置的波束#1，波束#2，波束#3，……中的至少一个，该转发器使用接收的该波束标识对应的波束在接入链路上进行转发；其中，网络设备配置的波束标识与波束之间的对应关系由转发器实现决定。
在一些实施例中，或者，转发器接收的该波束标识是该转发器上报的接入链路的波束标识中的至少一个，也就是说，由转发器确定并上报接入链路的波束标识，网络设备向转发器指示该转发器上报的波束标识中的至少一个。
例如，转发器向网络设备上报波束标识波束#1，波束#2，波束#3，……，当转发器需要在接入链路上进行转发时，网络设备向转发器指示的波束标识(即转发器接收的该波束标识)为该转发器上报的波束#1，波束#2，波束#3，……中的至少一个，该转发器使用接收的该波束标识对应的波束在接入链路上进行转发；其中，网络设备指示的波束标识与波束之间的对应关系由转发器实现决定。
在转发器接收的该波束标识是网络设备配置接入链路的波束标识中的至少一个的情况下，例如，该波束标识是该网络设备根据该转发器上报的信息配置的。
在一些实施例中，该转发器上报的信息包括：该接入链路支持的波束数量信息、该接入链路的波束之间的关系以及是否支持同时在不同该接入链路的波束上转发中 的至少一个。
在一些实施例中，该接入链路支持的波束数量信息包括以下中的至少一个：该接入链路支持的波束总数、该接入链路支持的转发波束总数、该接入链路支持的同时转发的波束总数以及不同类型的波束数量。
在一些实施例中，不同类型的波束是不同方向的波束，或者，不同宽窄的波束，或者，不同精度的波束。
另外，关于波束之间的关系以及波束的方向和宽窄将在下面详细说明。
在一些实施例中，是否支持同时在不同该接入链路的波束上转发，包括：支持同时转发的波束数；支持同时转发的波束精度相同或不同；以及支持同时转发的波束之间的关系中的至少一个。
对于转发器接收的该波束标识是网络设备配置接入链路的波束标识中的至少一个的情况，在上述示例中，网络设备根据该转发器上报的信息配置接入链路的波束标识。又例如，接入链路的波束标识是网络设备配置的，也就是说，网络设备不需要转发器上报信息，独立的确定接入链路的波束标识。
对于转发器接收的该波束标识是网络设备配置接入链路的波束标识中的至少一个的情况，该方法还可以包括：该转发器从网络设备接收该波束标识对应的波束之间的关系信息。也就是说，网络设备还向转发器指示接入链路的波束标识对应的波束之间的关系信息。
对于转发器接收的该波束标识是转发器上报的接入链路的波束标识中的至少一个的情况，该方法还可以包括：该转发器向该网络设备上报该波束标识对应的波束之间的关系信息。
在一些实施例中，网络设备按照转发器上报的接入链路的波束标识进行指示，也就是说，不需要网络设备对接入链路的波束标识进行处理。
或者，网络设备对转发器上报的接入链路的波束标识进行处理后再向该转发器重新指示波束标识。例如：网络设备根据一个参考值对转发器上报的接入链路的波束标识重新标号，例如，从转发器上报的波束#4开始标0,1,2,3。
下面，对波束之间的关系进行详细的说明。
在一些实施例中，波束之间的关系也可以称为波束之间的QCL(准共址，Quasi-Colocation)关系或者波束的空域关系(spatial relation)。
在一些实施例中，该波束之间的关系是不同波束标识对应的波束之间的关系。
例如，该波束之间的关系至少包括：不同波束标识对应的波束是不同方向的，或者，不同波束标识对应波束是同一方向不同宽窄的。
在一些实施例中，波束的宽窄也可以表述为波束的精度(精细度)或波束的类型。
图5是本申请实施例1的波束之间的关系的一示意图。如图5所示，波束标识波束#1对应的波束分别与波束#4、波束#5、波束#6对应的波束为同一方向的波束，波束#2对应的波束分别与波束#7、波束#8、波束#9对应的波束为同一方向的波束，波束#3对应的波束分别与波束#10、波束#11、波束#12对应的波束为同一方向的波束。
另外，波束标识波束#1对应的波束、波束#2对应的波束、波束#3对应的波束为不同方向的波束；波束#4、波束#5、波束#6对应的波束为不同方向的波束；波束#7、波束#8、波束#9对应的波束为不同方向的波束；波束#10、波束#11、波束#12对应的波束为不同方向的波束。
在一些实施例中，波束之间的关系可以包括类型1和类型2，其中，类型1是指两个的波束是不同方向的，例如图5中的波束#1对应的波束与波束#2对应的波束，波束#4对应的波束与波束#3对应的波束，波束#5对应的波束与波束#8对应的波束，波束#11对应的波束与波束#12对应的波束；类型2是指两个波束是同一方向不同宽窄(不同精度或类型)的，例如图5中的波束#1对应的波束与波束#4对应的波束，波束#2对应的波束与波束#9对应的波束。
如上所述，在一些实施例中，可以由网络设备确定接入链路的波束之间的关系，即不同的波束标识对应波束之间的关系，并指示给转发器。
例如，网络设备利用一个比特(bit)指示波束#1、波束#2对应的波束之间的关系是类型1还是类型2，例如，该比特指示“0”，则表示波束#1与波束#2对应的波束是类型1的关系；该比特指示“1”，则表示波束#1与波束#2对应的波束是类型2的关系；
又例如，网络设备指示同一集合中的波束标识对应的波束是同一方向不同宽窄(不同精度或类型)的波束，例如，集合1是{波束#1，波束#4，波束#5，波束#6}，集合2是{波束#2，波束#7，波束#8}；
又例如，网络设备指示一个集合中波束的宽窄(或精度或类型)相同的波束，例如，集合1是{波束#1，波束#2，波束#3}，集合2是{波束#5，波束#6，波束#7}。
如上所述，在一些实施例中，可以由转发器确定接入链路的波束之间的关系，即不同的波束标识对应波束之间的关系，并上报给网络设备。
例如，转发器利用一个比特(bit)上报波束#1对应的波束与波束#2对应的波束之间的关系是类型1还是类型2，例如，该比特指示“0”，则表示波束#1对应的波束与波束#2对应的波束是类型1的关系；该比特指示“1”，则表示波束#1对应的波束与波束#2对应的波束是类型2的关系；
又例如，转发器上报波束标识，同一集合中的波束标识对应的波束是同一方向的不同宽窄(不同精度或类型)的波束，例如，集合1是{波束#1，波束#4，波束#5，波束#6}，集合2是{波束#2，波束#7，波束#8}；
又例如，转发器上报一个集合中波束的宽窄(或精度或类型)相同的波束，比如集合1是{波束#1，波束#2，波束#3}，集合2是{波束#5，波束#6，波束#7}。
在一些实施例中，转发器可以支持上述示例中的一个上报方式，或者，转发器可以同时支持上述示例中的多个上报方式。
另外，在一些实施例中，可以默认规定不同波束标识对应波束之间的关系。
例如，规定波束标识对应的波束关系是类型1还是类型2；
又例如，规定某些波束标识对应的波束是同一方向不同宽窄(不同精度或类型)的波束；
又例如，规定某些波束标识对应的波束是相同宽窄(相同精度或类型)不同方向的波束。
如上所述，转发器接收的接入链路的波束标识是网络设备配置的或者转发器上报的。
另外，在一些实施例中，默认规定转发器的接入链路的波束信息。
例如，默认规定转发器支持的接入链路波束数最大为M个，例如8个或4个；
又例如，默认规定转发器支持的同时在M’个接入链路波束上转发；
又例如，默认规定转发器的接入链路波束之间的关系。
在一些实施例中，该转发器接收的该波束标识由第一数量的比特指示对应的波束标识。
例如，该第一数量由该接入链路的波束标识总数确定，或者，该第一数量由该接入链路支持的转发波束总数确定，或者，该第一数量由该转发器接收的该波束标识总 数确定。例如，波束标识由log 2M个比特指示对应标识数字，其中M为第一数量。
在一些实施例中，或者，该转发器接收的该波束标识由位图(bitmap)的方式指示对应的波束标识。
例如，该位图的比特数是该接入链路的波束标识总数，或者，该位图的比特数是该接入链路支持的转发波束总数，或者，该位图的比特数是该转发器接收的该波束标识总数。
在一些实施例中，网络设备指示该波束标识可以采用多种方式。
例如，方式1：该转发器接收的该波束标识(即网络设备指示的该波束标识)是该转发器上报的接入链路的波束标识中的至少一个，或者，该转发器接收的该波束标识是该网络设备配置的接入链路的波束标识中的至少一个。
也就是说，该转发器接收的该波束标识是该转发器上报的接入链路的波束标识的至少一个(全部或一部分)，或者，该转发器接收的该波束标识是该网络设备配置的接入链路的波束标识的至少一个(全部或一部分)。
例如，方式2：该网络设备通过RRC信令配置网络设备配置的接入链路的波束标识中的至少一个波束标识或转发器上报的接入链路的波束标识中的至少一个波束标识，也就是说，对于网络设备配置接入链路的波束标识的情况，RRC信令配置的是该网络设备配置的接入链路的波束标识中的至少一个波束标识，对于转发器上报接入链路的波束标识的情况，RRC信令配置的是该转发器上报的接入链路的波束标识中的至少一个波束标识；
并且，通过MAC CE激活第一部分波束标识，通过物理层信令的域指示第二部分波束标识，该第一部分波束标识包括该RRC信令配置的波束标识中的至少一个波束标识，该第二部分波束标识包括该第一部分波束标识中的至少一个波束标识，该转发器接收的该波束标识是该第二部分波束标识。其中，物理层信令例如是DCI。
以下通过具体的示例进行说明。
转发器最多被RRC信令配置个波束标识为了接入链路转发指定的服务小区内终端设备的传输。例如，M1由转发器的支持接入链路波束数量的能力确定，M1为正整数，例如为128。每个波束标识对应转发器的接入链路波束，其对应关系由转发器实现决定。
例如，为了转发器转发终端设备与网络设备之间下行和上行的传输，转发器被配 置最多128个波束标识的列表，其配置在RRC信令中。
该转发器接收在MAC CE中的激活指令，用于映射最多M2个波束标识，每个波束标识对应转发器的接入链路转发上行或下行的波束，其中，M2为正整数，M2小于或等于M1。
图6是本申请实施例1的MAC CE的一示意图。需要说明的是，图6所示的MAC CE仅是一个示例，本申请实施例的MAC CE可以采用各种其他的结构。
例如，如果RRC信令中配置了波束标识，MAC CE中的域Ti指示波束标识i(波束#i)的激活或去激活状态，否则忽略MAC CE中的域Ti。如图6所示，域Ti设置为1时指示波束标识i(波束#i)被激活，并且映射到DCI中指示接入链路转发波束标识的码字；域Ti设置为0时指示波束标识i(波束#i)被去激活，并且不被映射到DCI中指示接入链路转发波束标识的码字。
如果激活指令映射到DCI中的码字，转发器则应用DCI的码字指示的波束标识来转发终端设备与网络设备之间下行和上行的传输。DCI中映射波束标识的码字是按Ti设为1的顺序(升序)确定的，即第一个设为1的Ti映射DCI中的码字为0，第二个设为1的Ti映射DCI中的码字为1，以此类推。激活的波束标识数量最大为M2个。DCI中映射波束标识码字最多指示N个波束标识，DCI中指示波束标识域的码字有N log 2M2个，N为正整数，N小于或等于M2。
例如，激活的波束标识数最多为8个。如果DCI指示波束标识无效则DCI中码字为0比特，否则指示一个波束标识为3比特；
又例如，MAC CE中的域激活T4，T20，T22，则DCI中指示0则代表波束#4，指示1则代表波束#20，指示2则代表波束#22；
又例如，DCI指示波束标识的码字指示2个波束标识，DCI中码字为6个比特。
在一些实施例中，该转发器接收的该波束标识包括该网络设备指示的由该网络设备配置的或该转发器上报的第一波束标识，以及该网络设备通过RRC信令配置和MAC CE激活和物理层信令的域指示的第二波束标识。也就是说，该转发器接收的该波束标识是网络设备按照上述方式1和方式2指示的第一波束标识和第二波束标识。
在一些实施例中，可以根据转发的信号类型，确定网络设备按照上述方式1还是方式2指示转发该信号的波束对应第一波束标识还是第二波束标识。
例如，该转发器转发广播信号的波束对应于网络设备按照上述方式1指示的第一 波束标识，该转发器转发终端特定的信号的波束对应于网络设备按照上述方式2指示的第二波束标识。
在一些实施例中，还可以根据接收的波束配置是半静态波束配置还是动态波束配置来确定网络设备按照上述方式1还是方式2指示接收该波束配置的波束对应第一波束标识还是第二波束标识。
例如，该转发器接收半静态波束配置的波束对应于网络设备按照上述方式1指示的第一波束标识，该转发器接收动态波束配置的波束对应于网络设备按照上述方式2指示的第二波束标识。
在一些实施例中，还可以根据接入链路的波束的宽窄或类型或精度来确定网络设备按照上述方式1指示与该波束对应的第一波束标识还是按照方式2指示与该波束对应的第二波束标识。
例如，该转发器接入链路的宽波束对应于网络设备按照上述方式1指示的第一波束标识，该转发器接入链路的窄波束对应于网络设备按照上述方式2指示的第二波束标识；也可以说，该转发器接入链路的低精度波束对应于网络设备按照上述方式1指示的第一波束标识，该转发器接入链路的高精度波束对应于网络设备按照上述方式2指示的第二波束标识。
由上述实施例可知，转发器根据从网络设备接收的接入链路的波束标识，使用与该波束标识对应的波束进行接入链路上的转发，使网络设备能够调度转发器用于转发的接入链路波束，并使转发器能够确定转发的接入链路波束，因此，能够有效利用波束标识并完成终端与网络设备之间的转发。
