Description

信息指示方法、转发器和网络设备 技术领域
本申请涉及通信技术领域。
背景技术
与传统的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，除了传统电信频谱以外，5G系统也被部署在新频谱上，新频谱的频率明显高于3G和4G系统使用的传统电信频谱。例如，5G系统可以部署在毫米波波段(28GHz，38GHz，60GHz以及以上等等)。
根据无线信号的传播规律，其所在载波的频率越高、信号在传播过程中遇到的衰落越严重。因此，实际部署中，5G系统比以往的3G、4G系统更需要小区覆盖增强方法，特别是部署在毫米波频段的5G系统。如何更好地增强5G系统小区覆盖，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 Relay/Repeater)放大和转发终端设备与网络设备之间的通信信号，是比较常用的部署手段。射频转发器在3G系统和4G系统的实际部署中具有较为广泛的应用。通常来说，射频转发器是一种在射频域放大和转发网络设备与终端设备往来信号的设备。
发明人发现，针对5G系统在部署中遇到的覆盖问题，采用射频转发器进行覆盖增强是可行的解决方案之一。但是，传统转发器不具备与网络设备通信的能力，无法根据网络的实际情况对转发进行调整。因此，这样的转发器配置在5G系统中，虽然 能够一定程度帮助增强信号强度，但是不够灵活而无法应对复杂的环境变化，与在3G系统和4G系统中部署的同类型射频转发器相比转发效率和转发效果欠佳。
针对上述问题的至少之一，本申请实施例提供了一种信息指示方法、转发器和网络设备。转发器具有与网络设备通信的能力，能够在网络配置下更好地加强信号覆盖并应对环境变化(例如，在转发中减少对其它网络设备和终端设备的干扰等)，由此能够提高整个网络的传输效率。
根据本申请实施例的一方面，提供一种信息指示方法，包括：

其中，所述转发器至少基于所述第一信息和/或通信标准定义规则确定在第一时间使用第一波束在接入(AC)链路进行接收或者进行发送。

本申请实施例的有益效果之一在于：转发器获得第一信息；所述转发器至少基于所述第一信息和/或通信标准定义规则确定在第一时间使用第一波束在接入(AC)链路进行接收或者进行发送。由此，转发器能够基于第一信息和/或通信标准定义规则 确定AC链路的转发，可以更好地加强信号覆盖并应对环境与小区内主要业务的变化等，从而能够提高整个网络的传输效率。

具体实施方式
参照附图，通过下面的说明书，本申请的前述以及其它特征将变得明显。在说明书和附图中，具体公开了本申请的特定实施方式，其表明了其中可以采用本申请的原则的部分实施方式，应了解的是，本申请不限于所描述的实施方式，相反，本申请包括落入所附权利要求的范围内的全部修改、变型以及等同物。
在本申请实施例中，术语“第一”、“第二”等用于对不同元素从称谓上进行区分，但并不表示这些元素的空间排列或时间顺序等，这些元素不应被这些术语所限制。术语“和/或”包括相关联列出的术语的一种或多个中的任何一个和所有组合。术语“包含”、“包括”、“具有”等是指所陈述的特征、元素、元件或组件的存在，但并不排除存在或添加一个或多个其他特征、元素、元件或组件。
在本申请实施例中，单数形式“一”、“该”等包括复数形式，应广义地理解为“一种”或“一类”而并不是限定为“一个”的含义；此外术语“所述”应理解为既包括单数形式也包括复数形式，除非上下文另外明确指出。此外术语“根据”应理解为“至少部分根据……”，术语“基于”应理解为“至少部分基于……”，除非上下文另外明确指出。
在本申请实施例中，术语“通信网络”或“无线通信网络”可以指符合如下任意通信标准的网络，例如长期演进(LTE，Long Term Evolution)、增强的长期演进(LTE-A，LTE-Advanced)、宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)、高速报文接入(HSPA，High-Speed Packet Access)等等。
并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及未来的5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本申请实施例中，术语“网络设备”例如是指通信系统中将终端设备接入通信网络并为该终端设备提供服务的设备。网络设备可以包括但不限于如下设备：基站(BS，Base Station)、接入点(AP、Access Point)、收发节点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，IAB宿主等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。
在本申请实施例中，术语“用户设备”(UE，User Equipment)例如是指通过网络设备接入通信网络并接收网络服务的设备，也可以称为“终端设备”(TE，Terminal Equipment)。终端设备可以是固定的或移动的，并且也可以称为移动台(MS，Mobile Station)、终端、用户、用户台(SS，Subscriber Station)、接入终端(AT，Access Terminal)、站，等等。
终端设备可以包括但不限于如下设备：蜂窝电话(Cellular Phone)、个人数字助理(PDA，Personal Digital Assistant)、无线调制解调器、无线通信设备、手持设备、机器型通信设备、膝上型计算机、无绳电话、智能手机、智能手表、数字相机，等等。
再例如，在物联网(IoT，Internet of Things)等场景下，终端设备还可以是进行监控或测量的机器或装置，例如可以包括但不限于：机器类通信(MTC，Machine Type Communication)终端、车载通信终端、设备到设备(D2D，Device to Device)终端、机器到机器(M2M，Machine to Machine)终端，等等。
为了增强覆盖，3GPP Rel-17研究中引入RF repeater来转发终端设备(UE)和网络设备(基站)之间的传输。对于网络设备和终端设备来说，Rel-17中引入的RF repeater是透明的，即网络设备和终端设备并不知道RF repeater的存在。
图1是本申请实施例的应用场景的一示意图，如图1所示，为了方便说明，以一个网络设备(例如5G基站gNB)101、一个转发器(Repeater)102和一个终端设备(例如UE)103为例进行说明，本申请不限于此。
如图1所示，终端设备103与网络设备101建立连接并与其通信。为了增加通信质量，终端设备103与网络设备101之间传输的信道/信号经由转发器102进行转发。网络设备101，终端设备103与转发器102之间的信道/信号交互均采用基于波束的接收和发送方法。
如图1所示，网络设备101可以具有小区/载波，网络设备101、转发器102和终 端设备103可以在该小区进行转发/通信；但本申请不限于此，例如网络设备101还可以具有其他小区/载波。
在本申请实施例中，网络设备和终端设备之间可以进行现有的业务或者未来可实施的业务传输。例如，这些业务可以包括但不限于：增强的移动宽带(eMBB)、大规模机器类型通信(mMTC)、高可靠低时延通信(URLLC)和车联网(V2X)通信，等等。
传统转发器不具备与网络设备通信的能力，因此，传统转发器虽然能够帮助增强信号强度，但是不够灵活而无法应对复杂的环境变化，将传统转发器部署在5G网络(特别是部署在高频的5G网络)中可能引起对其它网络设备和/或终端设备的不必要的干扰，进而降低整个网络的传输效率(例如，吞吐量)。为了使得转发器的转发能够更为灵活以适应5G网络的特点，网络设备需要对转发器进行协助，并能够根据网络情况对转发器的转发进行配置。
3GPP Rel-18为了增强NR的覆盖，提出网络控制转发器(NCR，Network-controlled repeater)的方案，为网络设备与终端设备之间的信号进行转发。NCR通过控制链路可以与网络设备进行直接通信以辅助NCR的转发操作。
图2是本申请实施例的NCR的一示意图。如图2所示，NCR 202被配置在网络设备201和终端设备203之间。NCR 202可以包括如下两个模块/部件：转发器的移动终端(NCR-MT)和转发器的转发模块(NCR-Fwd)；NCR-Fwd也可称为NCR-RU的路由单元(NCR-RU)。NCR-MT用于与网络设备通信，NCR-Fwd用于转发往来于网络设备和终端设备之间的信号。
如图2所示，本申请实施例的NCR可以具有3个链路：控制链路(control link，C-link)，用于转发的回传链路(backhaul link，BH link))和接入链路(access link，AC link)。其中，C-link用于NCR与网络设备之间的通信。BH link用于转发器从网络设备接收待转发信号，或者，向网络设备转发来自终端设备的信号。AC link用于转发器向终端设备转发来自网络设备的信号，或者，接收来自终端设备的待转发信号。
发明人认识到，5G系统相对于以前的3G、4G系统等更为复杂，例如，能够支持更多种类的业务和终端类型，又例如，需要被部署在多种频段和场景等。与传统的RF repeater相比，NCR需要具备基于波束的功能。
图3是本申请实施例的NCR转发的一示意图。如图3所示，转发器在AC链路 使用发送波束将来自网络设备的信号转发出去。图4是本申请实施例的NCR转发的另一示意图。如图4所示，转发器在AC链路使用接收波束来接收用于转发给网络设备的信号。
但是，发明人发现：转发器如何确定AC链路的波束等信息，目前没有具体方案。即，转发器如何确定AC链路的转发信息(波束、时间、信号方向等)成为亟待解决的问题。
此外，在服务过程中，不同业务类型、终端类型的冲突也被允许，并且提供了系统的冲突解决方案。例如，当一个对可靠性和时延要求都很高的URLLC业务到达的时候，进行中的eMBB业务数据的传输可能被打断或者被放弃，以便让优先级更高的URLLC业务数据能够被及时、可靠地传输。除此以外，由于5G系统功能先进而复杂，因此网络侧在进行配置和调度的时候，可能会有重配置、以及改写等操作。NCR的主要目的是为了覆盖网络信号质量不佳的区域，被NCR服务的终端可以是各种各样的终端，因此，由NCR转发的网络侧与终端侧交互的信号可能具有不同的优先级等。
鉴于以上的理解，发明人还认为，考虑NCR在AC链路中如何避免或者处理波束指示等配置的冲突，是在设计服务于5G网络的NCR的过程中，进一步亟待解决的问题。
下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本申请的限制。
在本申请实施例中，转发器可以与网络设备通信，转发器可以接收网络设备发送的通信信道/信号，并进行信道/信号的解调/解码，由此获得网络设备发给该转发器的信息，以下将该信号处理过程称为“通信”。转发器还可以转发网络设备和终端设备之间传输的信道/信号，转发器不对该信道/信号进行解调/解码，可以进行放大等处理，以下将该信号处理过程称为“转发”。将“通信”和“转发”合称为“传输”。此外，“在AC链路上进行发送或进行接收”可以等价于“在AC链路上进行转发”，“在控制链路上进行发送或进行接收”可以等价于“在控制链路上进行通信”。以上术语仅为了方便说明，并不构成对本申请的限制。
为方便起见，可以将网络设备和转发器之间或者第三设备(例如终端设备)和转发器之间进行直接通信的信道/信号称为通信信号，在发送通信信号时，转发器需要 进行编码和/或调制，在接收通信信号时，转发器需要进行解码和/或解调。此外，可以将经由转发器转发的信道/信号称为转发信号，转发器对转发信号可以进行放大等信号处理，但不会进行解码和/或解调。
在本申请实施例中，转发器还可以表述为直放站、射频转发器、中继器、射频中继器；或者也可以表述为直放站节点、转发器节点、中继器节点；或者还可以表述为智能直放站、智能转发器、智能中继器、智能直放站节点、智能转发器节点、智能中继器节点，等等，本申请不限于此。
在本申请实施例中，网络设备可以是终端设备的服务小区的设备，也可以是转发器所在小区的设备，还可以是转发器的服务小区的设备，也可以是转发器的父节点(Parent node)，本申请对该转发器的名称不做限制，只要能实现上述功能的设备，都包含于本申请的转发器的范围内。

例如，网络侧在指示波束的时候，可以同时指示该波束的转发方向。
再例如，AC链路的收发具有一致性，也就是说，转发上行或者下行的波束具有一致性。这种情况下，即使网络侧不指定这个波束是上行的还是下行的，例如仅仅指示一个波束(例如指示该波束的索引)，网络侧与NCR也不会就这个波束是哪一个波束产生歧义。在这种情况下，在具体的实施方式中，NCR也可以结合其它信息(例如，TDD config)对被指示的该波束用于转发的信号的传播方向进行判断/确定。采用这种实施方式，可以减少重复指示。
在一些实施例中，转发器确定在所述第一时间的上行时间单位使用所述第一波束在所述接入链路进行接收。
在一些实施例中，转发器确定在所述第一时间的下行时间单位使用所述第一波束在所述接入链路进行发送。
在一些实施例中，转发器确定在所述第一时间的至少一个灵活时间单位使用所述第一波束在所述接入链路进行接收或进行发送。
在一些实施例中，转发器确定在所述第一时间的至少一个灵活时间单位在所述接入链路不进行接收和不进行发送。
在一些实施例中，第一信息用于指示第一时间，所述第一时间与第一信号相关。第一信号不由所述转发器生成，和/或，所述转发器不对所述第一信号进行解调解码。即，第一信号为前述的转发信号。
例如，第一信息指示转发公共信号的时间(第一时间)，而第一波束由NCR自行确定，或者按照预定义规则确定、或者被随机确定。转发器不对其所转发的信号进行解调等信号处理，转发器仅对其所转发的信号进行放大。转发器在AC链路使用的波束性能，可以由第三方设备(例如终端设备)测量和/或网络侧测量的结果进行评估。转发器不对其所转发的信号进行任何测量。因此，波束的名字与波束的具体对应关系，不会影响网络侧对转发器的转发行为的指示和配置。由NCR自行确定波束，可以降低网络侧的指示/配置信令开销，减小网络侧的复杂度。
在一些实施例中，所述转发器确定所述第一波束，所述第一波束与所述第一信号相关；所述转发器确定在所述第一时间使用所述第一波束在所述接入链路接收或者发送所述第一信号。
在一些实施例中，所述第一信号至少包含索引为n的SSB；所述第一信息包含系统信息，所述第一时间至少包含所述SSB索引n所对应的时间单位。
在一些实施例中，转发器确定用于在所述接入链路进行发送的所述SSB索引n。
在一些实施例中，所述SSB索引n由网络侧配置或指示，和/或，所述SSB索引n由通信标准预定义，和/或，所述SSB索引n预先设定在所述转发器内。
在一些实施例中，转发器确定用于在所述接入链路发送所述索引为n的SSB的所述第一波束。
在一些实施例中，转发器确定用于在所述接入链路发送的SSB数目N和/或用于在所述接入链路发送的N个SSB的索引，所述SSB索引n为所述N个SSB的索引之一；所述SSB数目N和/或N个SSB的索引被预先设定，或者，所述SSB数目N和/或N个SSB的索引由通信标准预定义，或者，所述SSB数目N和/或N个SSB的索引由网络侧为所述转发器配置或指示。
在一些实施例中，所述SSB数目N的取值被预先设定，转发器向网络侧上报所述SSB数目N。以及，网络侧为转发器配置/指示所述N个SSB的索引。
在一些实施例中，所述转发器确定用于在所述接入链路发送所述N个SSB的N个波束，以及确定所述N个波束与所述N个SSB的对应关系。
例如，N也可以为用于转发SSB的波束数，和/或，N也可以为转发器在AC链路支持的转发波束数，和/或，N也可以为转发器在AC链路使用的转发波束数。
在一些实施例中，转发器根据网络侧配置和/或指示确定用于在所述接入链路发送所述N个SSB的N个波束，或者，所述转发器根据通信标准定义规则确定用于在所述接入链路发送所述N个SSB的N个波束，或者，所述转发器自行确定用于在所述接入链路发送所述N个SSB的N个波束。例如，通信标准定义规则为索引号小的SSB对应索引号小的波束。
在一些实施例中，第一波束与所述SSB索引n一一对应，且所述一一对应关系保持不变，直到所述转发器被重启和/或被重配置。如此可以避免网络侧为NCR配置/指示AC链路转发波束时的歧义。
例如，NCR自行确定使用的波束，且在确定后不再改变。
在一些实施例中，第一时间还包含与所述SSB索引n相应的用于发送随机接入前导(RACH preamble)的时间单位或随机接入机会(RACH occasion)。所述第一信号还包含使用所述与SSB索引n相应的用于发送随机接入前导(RACH preamble)的时间单位或随机接入机会(RACH occasion)相应的时域和/或频域资源来进行传输的 信号。
在一些实施例中，所述第一信号包括以下信号或信道或信息的至少之一，或者，所述第一信号与以下信号或信道或信息的至少之一相关：
同步信号(SS)，
同步信号块(SSB)，
系统信息块(SIB)，
主信息块(MIB)，
Msg1(随机接入信道，RACH)，
Msg2,
Msg3,
Msg4,
Msg5,
用于调度(或触发)Msg1和/或Msg2和/或Msg3和/或Msg4和/或Msg5的物理下行控制信道(PDCCH)，
用于承载Msg2和/或Msg4的物理下行共享信道(PDSCH)，
用于承载Msg3和/或Msg5的物理上行共享信道(PUSCH)，
信道状态信息参考信号(CSIRS)，

调度请求(SR)，
用于承载SR的物理上行控制信道(PUCCH)。
在一些实施例中，转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路接收或者发送所述第一信号。
在一些实施例中，所述第一信息包括所述第一信号所在的时域和/或频域的位置信息，和/或，所述第一信息由一个或者一个以上信令承载。
在一些实施例中，所述第一信息至少包含系统信息；所述转发器至少根据所述第 一信息确定在所述第一时间接收或者发送与所述第一信号相关的信号。
以上对于第一信息、第一波束、第一时间等进行了示意性说明，本申请不限于此。
由于AC链路是NCR的转发链路，因此，NCR可能知道其所转发的信号是什么信号，也可能不知道所转发的信号是什么信号。或者，换句话说，即使NCR不知道其转发的是什么信号，也不影响该NCR对信号进行转发。
网络侧配置NCR在指定的时间、使用指定的波束，对指定传输方向(例如上行或者下行，或，从网络侧到终端侧或者从终端侧到网络侧)的信号进行转发即可。这样，减少了通信协议的复杂度，并降低了NCR的实现成本，有助于增加NCR设备的性价比，以便NCR设备能更好、更多地服务于实际网络服务。
另一方面，NCR也可以识别其所转发的信号的类型，例如，该信号是公共信号(例如：SS，SSB，SIB，MIB，RACH等)或者其它信号(例如：某一个被该NCR服务的终端设备的专有信号等)。这样，具有了这种能力的NCR设备，可以一定程度的自主获取该信号转发的相关信息，从而减轻网络侧设备的复杂度，降低网络设备的成本，也减少了网络侧与NCR之间的交互的配置信息，从而让更多的时域/频域/空域资源用于传输业务数据进而提高频谱使用效率。
以下再示意性说明NCR在AC链路中如何避免或者处理波束指示等配置的冲突。
在一些实施例中，转发器获得第三信息，所述第三信息与第二时间相关，所述第二时间与所述第一时间至少部分重叠；
所述第三信息还用于指示所述转发器在所述接入链路进行转发的第二波束，和/或，所述第三信息还用于指示所述至少部分重叠的时间内、所述转发器在所述接入链路的转发方向，和/或，所述第三信息还用于指示与所述至少部分重叠的时间相关的传输方向和/或开关状态。
以下先示意性说明所述第二波束与所述第一波束不同的情况，即波束出现冲突。以下以在冲突解决中引入优先级概念为例进行说明，所述第一波束的优先级高于或等于所述第二波束的优先级；本申请不限于此。
在一些实施例中，所述第三信息至少用于指示所述转发器在所述第二时间使用所述第二波束在所述接入链路进行转发，所述转发方向与所述转发器在所述第一时间确定的转发方向一致或者不一致，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收或进行发送。
例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行接收，所述第三信息用于指示所述转发器在所述第二时间使用所述第二波束在所述接入链路进行接收，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行发送，所述第三信息用于指示所述转发器在所述第二时间使用所述第二波束在所述接入链路进行发送，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行发送。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行接收，所述第三信息用于指示所述转发器在所述第二时间使用所述第二波束在所述接入链路进行发送，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行发送，所述第三信息用于指示所述转发器在所述第二时间使用所述第二波束在所述接入链路进行接收，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行发送。
在一些实施例中，所述第一波束的优先级由网络侧配置和/或指示，或者所述第一波束的优先级由通信标准定义，或者所述第一波束的优先级由所述转发器至少根据所述第一信息确定。
在一些实施例中，所述第一时间包括的至少一个时间单位的优先级高于或等于预设优先级，或者，高于或等于所述第二时间中任意一个时间单位的优先级，或者，高于或等于所述至少部分重叠的时间中任意一个时间单位的优先级。在冲突解决中，转发器确定的、与所述第一时间相关的转发优先级高于或者等于与所述第二时间相关的转发优先级。
例如，所述时间单位的优先级由网络侧配置和/或指示，或者所述时间单位的优先级由通信标准定义，或者所述时间单位的优先级至少由与所述时间单位相关的信号确定。
在一些实施例中，所述第三信息还用于指示所述转发器在所述接入链路进行转发的第二波束，其中，所述第三信息指示所述转发器在所述第二时间使用所述第二波束 在所述接入链路接收或者发送第二信号；所述第二信号的优先级低于或等于所述第一信号的优先级。在冲突解决中，转发器确定的、与所述第一信号相关的转发优先级高于或者等于与所述第二信号相关的转发优先级。
在一些实施例中，所述第一信号和/或所述第二信号的优先级由通信标准定义，或者，所述第一信号和/或所述第二信号的优先级由网络侧配置和/或指示。
在一些实施例中，所述第一信号的优先级最高。
例如，第一信号的优先级等于或者高于NCR在AC链路上接收或者发送的其它信号的优先级；或者，第一信号的优先级等于或者高于所述第一时间内NCR在AC链路上接收或者发送的其它信号；或者，NCR在AC链路上接收或者发送的信号优先级分为M个等级，所述第一信号的优先级为最高等级。
在一些实施例中，所述第一信息由半静态信令承载和/或由OAM实体配置，所述第三信息由动态信令承载。例如，半静态信令承载或者OAM配置的第一信息的优先级高于或等于动态信令承载的第三信息的优先级。在冲突解决中，由半静态信令承载或者OAM配置的第一信息相关的转发优先级高于或者等于由动态信令承载的第三信息相关的转发优先级。
由此，可以在冲突发生的时候，有效保证更为重要的公共信号的转发，进而避免因为公共信号传输质量不佳造成的终端设备接入网络失败、链路失败、波束失败等不良后果。半静态信令可以用于指示与比较重要的、周期发送或者接收的、公共信号相关的转发，例如SSB信号、SIB信号以及可能包含RACH的信号等。动态信令承载可以用于指示与动态或者较为动态的数据相关的转发，例如被NCR服务的终端设备的PDSCH和/或PUSCH等等。
在一些实施例中，所述第一信息由动态信令承载，所述第三信息由半静态信令承载和/或由OAM指示，或者，所述第三信息由动态信令承载；所述半静态信令包括MAC CE和/或RRC信令；所述转发器在接收所述第一信息之前接收所述第三信息。
由此，可以通过动态信令对信息进行改写。例如，采用这种方法，可以保证较为重要的待转发信号得到可靠、高效的转发。在被NCR服务的终端中，其中一个终端有对可靠性和时延要求都很高的URLLC业务到达的时候，需要发送或者接收URLLC业务信号。网络侧可以是使用动态信令改写转发配置/指示，以保证该URLLC业务信号得到可靠、及时的转发。
在一些实施例中，所述第一信息由半静态信令承载，所述第三信息由半静态信令承载和/或由OAM指示和/或动态信令承载；所述半静态信令包括MAC CE和/或RRC信令；所述转发器在接收所述第一信息之前接收所述第三信息。
由此，可以通过半静态信令对信息进行改写(或者更新，或者重配置等)。例如，采用这种方法，网络侧对周期发送的公共信号的发送进行调整时，可以允许网络侧对周期发送的公共信号的转发配置进行改写，以便转发器适应调整后的公共信号的转发。
上述实施方法可以结合，例如应用在不同的场景以便为转发器的转发提供更好的灵活性同时还能保证重要信号的转发。
以下再示意性说明传输方向不一致的情况，即传输方向出现冲突。
在一些实施例中，所述第三信息还用于指示与所述至少部分重叠时间相关的传输方向和/或开关状态，其中，所述第三信息至少用于指示所述至少部分重叠时间的一个时间单位的信号传输方向；其中，所述一个时间单位的信号传输方向和所述转发器根据所述第一信息确定的在所述第一时间使用所述第一波束在所述接入链路上的信号传输方向不一致。
在一些实施例中，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收或进行发送。
例如，所述转发器确定在所述第一时间使用所述第一波束在所述接入链路进行接收(上行)，所述第三信息至少用于指示所述至少部分重叠时间中的一个时间单位为下行时间单位或者灵活时间单位。
再例如，所述转发器确定在所述第一时间使用所述第一波束在所述接入链路进行发送(下行)，所述第三信息至少用于指示所述至少部分重叠时间中的一个时间单位为上行时间单位或者灵活时间单位。
在一些实施例中，所述转发器在所述信号传输方向不一致的时间单位内在所述接入链路不进行接收和/或不进行发送。
例如，所述转发器确定在所述第一时间使用所述第一波束在所述接入链路进行接收(上行)，所述第三信息至少用于指示所述第一时间包含的时间单位中的一个时间单位为下行时间单位或者灵活时间单位；所述转发器在所述下行时间单位或者灵活时间单位不进行接收，或者，在所述第一时间不进行接收。
再例如，所述转发器确定在所述第一时间使用所述第一波束在所述接入链路进行 发送(下行)，所述第三信息至少用于指示所述第一时间包含的时间单位中的一个时间单位为上行时间单位或者灵活时间单位；所述转发器在所述上行时间单位或者灵活时间单位不进行发送，或者，在所述第一时间不进行发送。
以下再示意性说明OFF时间的情况，即转发时间与OFF时间出现冲突。
在一些实施例中，所述第三信息至少用于指示所述第一时间包含的时间单位中至少一个时间单位不用于接收或发送。该不用于接收或发送的所述至少一个时间单位为关闭(OFF)时间单位，或者，为休眠(sleep/dormancy)时间单位，或者，为空(null)时间单位。
在一些实施例中，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收或进行发送。例如，由于第一信号对于终端设备的初始接入等非常重要，即使是在OFF的状态下，也需要对其进行转发。
在一些实施例中，所述转发器在所述被指示为不用于接收或发送的时间单位内在所述接入链路上不进行接收和/或不进行发送。由此，NCR不在OFF时间进行转发，可以提高节能效率。
在一些实施例中，所述第三信息由信令承载，所述信令至少用于指示关闭(OFF)时间。例如，所述信令还用于指示TDD UL DL配置，所述OFF为TDD UL DL配置中时间单位的一个状态。例如，所述信令为用于指示OFF时间的专用信令。例如，所述信令为DRX信令。
在一些实施例中，所述信令还用于指示上行时间单位，和/或，下行时间单位，和/或，灵活时间单位。例如，所述信令至少用于指示TDD UL DL配置。
以下再示意性说明C-link的情况，即转发链路与控制链路出现冲突。
在一些实施例中，所述转发器获得第四信息，所述第四信息与第三时间相关，所述第三时间与所述第一时间至少部分重叠。
在一些实施例中，所述第四信息至少用于指示所述转发器在所述第三时间在控制链路接收来自网络侧的信号或向网络侧发送信号。
在一些实施例中，所述转发器在所述第三时间在所述控制链路接收来自网络侧的信号或向网络侧发送生成的信号。
由此，NCR优先保证与网络设备之间的连接，避免因为与网络侧的连接不可靠而影响AC链路的转发。
例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行接收，所述第四信息用于指示所述转发器在所述第三时间在所述控制链路进行接收；所述转发器不在所述至少部分重叠时间在所述接入链路进行接收。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行发送，所述第四信息用于指示所述转发器在所述第三时间在所述控制链路进行发送；所述转发器不在所述至少部分重叠的时间在所述接入链路进行发送。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行接收，所述第四信息用于指示所述转发器在所述第三时间在所述控制链路进行接收；所述转发器不在所述第一时间在所述接入链路进行接收。

在一些实施例中，所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收或进行发送。
由此，NCR优先保证AC链路的稳定性，有助于保护高优先级终端设备的传输，例如有URLLC业务的终端设备。
例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行接收，所述第四信息用于指示所述转发器在所述第三时间在所述控制链路接收来自网络侧的信号；所述转发器不在至少部分重叠的时间在所述控制链路接收来自网络侧的信号。
再例如，所述转发器至少基于所述第一信息确定在所述第一时间使用所述第一波束在所述接入链路进行发送，所述第四信息用于指示所述转发器在所述第三时间在所述控制链路向网络侧发送信号；所述转发器不在至少部分重叠的时间在所述控制链路向网络侧发送信号。

以及所述信号被所述转发器解调或者解码。
以上示意性说明了NCR在AC链路中如何处理波束指示等配置的冲突，本申请不限于此。为了避免冲突，网络侧和转发器也可以遵循一定的策略或行为。
以下再对网络侧避免冲突的行为进行示意性说明。
在一些实施例中，网络侧不发送与所述第一信息不一致的指示信息；
在一些实施例中，网络侧不指示所述转发器在所述第一时间使用所述第一波束以外的波束进行发送或者进行接收。
在一些实施例中，网络侧不指示所述第一时间为OFF时间。
在一些实施例中，在所述第一信息至少用于指示所述转发器在所述第一时间使用所述第一波束在所述接入链路进行接收的情况下，网络侧不指示所述第一时间包含下行时间单位和/或灵活时间单位。

在一些实施例中，在所述第一信息至少用于指示所述转发器在所述第一时间使用所述第一波束在所述接入链路进行发送的情况下，所述转发器不期望被指示所述第一时间包含上行时间单位和/或灵活时间单位。
以上对于处理或避免冲突进行了示意性说明，以下再对优先级进行进一步说明。
在一些实施例中，可以表现为波束的优先级：一部分波束的优先级高于另一部分的优先级。
例如，用于转发某些信号的波束的优先级高。例如，用于转发SSB等高优先级信号的波束高。
再例如，网络侧配置一部分波束的优先级高，例如指定一部分波束调度index；或者，网络侧配置或指示一个波束的优先级。
再例如，事先约定某些信令指示的波束优先级高，例如OAM配置的波束优先级高，和或，半静态指示的波束优先级高，和或，动态指示的波束优先级高。
在一些实施例中，可以表现为转发信号的优先级：转发信号本身具有优先级。
例如，优先级可能较高的信号：至少包括以下之一：SS，SSB，SIB，MIB，RACH， 用于调度Msg2和或Msg3和或Msg4和或Msg5的PDCCH，用于承载Msg2和或Msg4的PDSCH，用于承载Msg3和或Msg5的PUSCH，CSIRS，SRS等。当然，也可以是上述信号以外的信号，本申请不以此为限。
再例如，NCR可以辨别具有较高优先级的信号，则用于转发该信号的波束与其它波束冲突时，NCR使用转发该信号的波束进行发送和或接收。
再例如，NCR可以辨别具有较高优先级的信号和部分或者全部其它信号，则用于转发该信号的波束与其它波束(例如用于转发部分或者全部其它信号，或者不确定其所转发信号的波束)冲突时，NCR使用转发该信号的波束进行发送和或接收。
再例如，被NCR服务的终端设备用于汇报BFR(beam failure report)的信号也可能优先级更高，这样让网络侧及时收到终端侧的BFR并进行适当处理，以避免发生进一步的更大的链路失败等。
再例如，信号优先级是由网络侧指示的。
在一些实施例中，可以表现为指示/配置信息、信令的优先级。
例如，OAM配置的波束优先级高，和/或，半静态指示的波束优先级高，和/或，动态指示的波束优先级高。
再例如，上述例子里重要的信号，大多与被服务的终端设备的初始接入、信道追踪、信道测量等关键的流程和能力相关。因此半静态信令或者由OAM配置的信令可能优先级更高一些。
再例如，当NCR所服务的终端设备中有较需要对可靠性和时延要求较高的业务的时候，网络侧可能会发送动态信令，为NCR指示新的传输波束。在这种情况下，优先级有可能分为三类，例如，用于转发SSB等的波束优先级最高，动态改写的优先级次之，其它指示的优先级较低。
在一些实施例中，可以表现为转发方向的优先级：转发方向具有优先级。
例如，波束冲突可能发生在上行转发与下行转发之间，下行转发波束可以更为优先，在通信中网络侧的优先级较高，可以保障被该网络设备服务的更多终端设备的业务。
又例如，波束转发方向冲突中，上行转发波束可以更为优先，以便让网络侧及时获得NCR所服务的终端设备的请求或者上报的信息。
在一些实施例中，可以表现为该波束使用或者转发的时间单位/时间段的优先级。
例如，NCR可以确定(根据收到的指示或者自行获取的系统信息)较为重要的信号可能在哪些时间需要被转发，这些时间或者时间段优先级较高，与这些时间或者时间段相关的波束在波束冲突中具有更高优先级。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
根据本申请实施例，转发器获得第一信息；所述转发器至少基于所述第一信息和/或通信标准定义规则确定在第一时间使用第一波束在接入(AC)链路进行接收或者进行发送。由此，转发器能够基于第一信息和/或通信标准定义规则确定AC链路的转发，可以更好地加强信号覆盖并应对环境与小区内主要业务的变化等，从而能够提高整个网络的传输效率。
