  • Traditional repeaters do not have the ability to communicate with network devices. Therefore, although traditional repeaters can help enhance signal strength, they are not flexible enough to cope with complex environmental changes. Deploying traditional repeaters in 5G networks (especially in high-frequency 5G networks) may cause unnecessary interference to other network devices and/or terminal devices, thereby reducing the transmission efficiency of the entire network (for example, throughput). In order to make the forwarding of repeaters more flexible to adapt to the characteristics of 5G networks, network devices need to assist repeaters and be able to configure the forwarding of repeaters according to network conditions.

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之一。
另一方面，相比于传统的3G和4G系统，5G系统采用了更为高级的多天线传播技术以及相应的传输设备。为了支持更为灵活和复杂的业务，5G系统的复杂度高于3G和4G系统。相应地，5G系统的耗电也高于3G和4G系统。如何降低5G系统的功耗，节省能源开销，也是亟待解决的问题之一。

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/信号交互可采用基于波束的接收和发送方法。波束可以为固定波束或者自适应波束。
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主要用于与网络设备通信，NCR-Fwd主要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AC链路(例如来自终端设备)的信号。AC link用于转发器(例如，向终端设备)转发来自网络设备的信号，或者，接收用于转发至BH链路的信号(例如，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需要具备基于波束收发(转发)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。
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。本申请实施例的转发器可以工作在第一频率范围(FR1)，或者，也可以工作在第二频率范围(FR2)，还可以工作在第一频率范围(FR1)和第二频率范围(FR2)；关于FR1和FR2的具体内容可以参考相关技术。
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。
在本申请实施例中，波束(beam)也可以表述为波瓣、参考信号(RS，reference signal)、传输配置指示(TCI，transmission configuration indication)、空域滤波器(spatial domain filter)等；或者，也可以表述为波束索引、波瓣索引、参考信号索引、传输配置指示索引、空域滤波器索引等。上述参考信号例如为信道状态信息参考信号(CSI-RS，channel state Information reference signal)、探测参考信号(SRS，sounding reference signal)、供转发器使用的RS、由转发器发送的RS等。上述TCI也可以表述为TCI状态(state)。本申请实施例不限于此。
第一方面的实施例
本申请实施例提供一种转发器的指示方法，从转发器一侧进行说明。
图5是本申请实施例的转发器的指示方法的一示意图，如图5所示，该方法包括：
501，转发器接收来自网络设备的配置信息，其中所述配置信息至少配置/指示第一资源和/或第二资源和/或第三资源；以及
502，所述转发器根据所述配置信息在所述第一资源进行转发和/或在所述第二资源不进行转发。
值得注意的是，以上附图5仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其他的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图5的记载。
在本申请实施例中，至少部分第一资源和/或第二资源和/或第三资源可以被该配置信息配置和/或指示，和/或，至少部分第一资源和/或第二资源和/或第三资源可以被预定义或者根据预先规则确定。但本申请不限于此，例如全部资源都可以被配置信息配置和/或指示，或者，全部资源都可以被预定义或者根据预先规则确定。
在一些实施例中，网络设备可以为转发器配置第一资源、第二资源、第三资源中的至少两种。第一资源可以用于转发，可以是针对转发的可用资源(例如称为硬资源或者ON资源)，第二资源不用于转发，可以是针对转发的不可用资源(例如称为NA资源或者OFF资源)，第三资源可以用于转发，可以是针对转发的未定资源(例如称为灵活资源或软资源)；本申请不限于此。
例如，网络设备可以支持第一资源、第二资源和第三资源，在配置时为转发器配置该三种资源。再例如，网络设备可以支持第一资源、第二资源和第三资源，但在配置时为转发器配置其中的至少两种。又例如，网络设备可以支持第一资源、第二资源和第三资源中的其中两种资源，在配置时为转发器配置这两种资源或者其一。本申请不限于以上的方式。
在一些实施例中，所述转发器在所述第一资源处于开启(ON)状态或者可用(available)状态或者硬(hard)状态。例如，所述开启(ON)状态为待机状态或者能够进行转发的状态。所述待机状态为默认关闭(default OFF)但收到指示就能转发的状态。例如，转发器可以在转发状态也可以不在转发状态，在没有转发状态的情况下，转发器可以快速地进入转发状态。又例如，所述开启(ON)状态为进行转发的状态。转发器在所述第一资源进行转发。
在一些实施例中，在所述能够进行转发的状态下，在有波束配置的情况下(例如转发器的工作频段位于FR2)，至少部分第一资源被配置有用于转发的波束，例如，转发 器的至少部分第一资源被配置有对应的波束。转发器在该至少部分第一资源使用与之对应的波束进行转发。
在一些实施例中，在所述能够进行转发的状态下，在没有波束配置的情况下(例如转发器的工作频段位于FR1)，默认波束和/或固定波束被用于转发。例如，转发器的至少部分第一资源资源对应默认波束和/或固定波束。转发器在该至少部分第一资源使用默认波束和/或固定波束进行转发。
在一些实施例中，在所述进行转发的状态下，在有波束配置的情况下(例如转发器的工作频段位于FR2)，转发器的所有第一资源都被配置有对应的波束。转发器在第一资源使用与之对应的波束进行转发。
在一些实施例中，在所述进行转发的状态下，在没有波束配置的情况下(例如转发器的工作频段位于FR1)，转发器的所有第一资源资源都对应默认波束和/或固定波束。转发器在第一资源使用默认波束和/或固定波束进行转发。
在以上的说明中，“能够进行转发”可以认为转发器具有进行转发的能力，和/或，转发器在该第一资源上可以转发，但该第一资源实际上并不一定被用于转发。“进行转发”可以认为是转发器被指示实施转发，或者转发器会实施转发行为，或者转发器在该第一资源上可以转发，和/或，该第一资源实际上被用于转发。以上说明仅为了更清楚地对转发进行阐述，并不构成对本申请的限制。
此外，在本申请的上下文中，“开启状态”“关闭状态”“可用状态”“不可用状态”“硬状态”“软状态”“灵活状态”等等可以是针对转发器的，即转发器可以具有这些状态，也可以是针对资源的，即资源可以具有这些状态。本领域技术人员能够理解以上这些术语在本申请中的具体含义。
在一些实施例中，所述第一资源的一个时间单位对应有转发波束。例如，每个时间单位都有对应的转发波束。又例如，至少部分时间单位有对应的波束。上述的时间单位可以是时隙、符号、子帧或小时隙(mini-slot)的其中之一或任意组合，本申请不限于此。
例如，所述转发波束被网络设备配置或指示，或者根据标准预定义规则确定，或者被预设定(例如出厂前)。
在一些实施例中，所述转发器在所述第一资源对应的开启(ON)状态下使用所述转发波束。例如，所述转发波束为回传(BH)链路上的波束和/或接入(AC)链路上的波束。
例如，所述转发器使用所述回传(BH)链路上的波束接收来自所述网络设备的通信信号，和/或，所述转发器使用所述回传(BH)链路上的波束向所述网络设备发送通信信号。
例如，所述转发器使用所述接入(AC)链路上的波束接收来自所述网络设备的转发信号，和/或，所述转发器使用所述接入(AC)链路上的波束向所述网络设备发送转发信号。
在一些实施例中，该至少部分或全部第一资源对应的转发波束由半静态信令配置。半静态信令例如为无线资源控制(RRC)信令、MAC CE等。
在一些实施例中，所述第一资源和/或所述转发波束由半静态信令配置。所述第一资源和所述转发波束可以被相同的信令配置，或者，所述第一资源和所述转发波束也可以被不同的信令配置。
在一些实施例中，所述第一资源具有最高优先级。
在一些实施例中，所述第一资源的波束指示只能被重配置(reconfigure)不能被改写(override)。
例如，如果第一资源被一个半静态信令配置为硬资源(ON资源)，则该第一资源能被又一个相同的半静态信令重配置为软资源(灵活资源)或者不可用资源(OFF资源)，或者被取消/抹除/移除状态。
又例如，如果第一资源对应的转发波束由半静态信令配置和/或指示，则该转发波束能被又一个相同的半静态信令重配置相同的转发波束，或者，该转发波束能被又一个相同的半静态信令重配置不同的转发波束，或者该转发波束被又一个相同的半静态信令取消/抹除/移除。可选地，该转发波束不能被其它信令(例如一个DCI信令或者一个其它半静态信令)改写(override)。也即，转发器不期待接收到一个为该第一资源指示和/或配置另一个转发波束的其它信令，和/或，网络设备不会向转发器发送一个为该第一资源指示和/或配置另一个转发波束的其它信令。
在一些实施例中，所述网络设备通过第一信令指示所述第一资源，通过第二信令为所述第一资源配置第一波束。
例如，所述第一信令指示所述第一资源的如下至少之一或任意组合：起始位置、偏移量、周期、结束位置；本申请不限于此，还可以指示第一资源的其他属性。
在一些实施例中，所述第二信令指示所述第一波束，和/或，所述第二信令指示所述第一波束对应的时域资源。
例如，第二信令可以直接指示第一波束，或者也可以直接指示第一波束对应的时域资源，或者还可以同时指示第一波束和其对应的时域资源。
在一些实施例中，所述第一资源和所述第一波束对应的时域资源部分重叠，或者，所述第一资源和所述第一波束对应的时域资源全部重叠(重合)，或者，所述第一资源至少包含所述第一波束对应的时域资源。
在一些实施例中，所述第一资源能够被另一第一信令重配置(reconfigure)。
例如，如果第一资源被一个半静态信令(RRC信令)配置为硬资源(ON资源)，则该第一资源还可以被另一个相同的半静态信令(RRC信令)重配置为软资源(灵活资源)或者不可用资源(OFF资源)或者硬资源(ON资源)。
在一些实施例中，所述第一波束只能够被另一第二信令重配置(reconfigure)，不能够被其他信令改写(override)。
例如，如果第一波束被一个半静态信令(RRC信令)配置，则该第一波束只能被另一个相同的半静态信令(RRC信令)重配置，而不能由其它信令(其它RRC信令或DCI或者MAC CE)重置。
在一些实施例中，所述第一信令和所述第二信令为同一信令。
例如，第一信令为转发器指示第一资源，且第一信令还指示与该第一资源的至少部分或全部资源对应的第一波束。
再例如，第二信令为转发器指示第一波束，该第一波束对应的时频资源即为第一资源。
在一些实施例中，所述第一信令和所述第二信令为不同的信令。
由此，网络设备为转发器配置不能够被其它信令的改写的第一资源(例如改写资源或者改写与第一资源相应的转发波束)，可以确保使用第一资源和相应的转发波束进行转发的稳定性，进而减少网络设备和转发器之间不必要的误解，以及避免因为误解导致的错误转发及其产生的对网络性能的影响。
例如，在第一资源进行转发的信号，可以是重要且对稳定性要求较高的信号，例如用于终端设备进行初始接入的公共信号，SSB、SIB、CORESET 0和/或RACHoccasion、CSI-RS等参考信号，等等。
以上对于第一资源或ON状态等进行了示意性说明，以下再说明第二资源或不可用状态。
在一些实施例中，所述转发器在所述第二资源处于关闭(OFF)状态或者不可用 (unavailable)状态。
例如，所述转发器在第二资源不转发信号。
再例如，所述转发器不期待收到与所述第二资源相关的动态指示转发的信令，和/或，所述转发器不期待收到与所述第二资源相关的配置/指示转发的信令，和/或，所述转发器在所述第二资源不期待收到配置/指示转发波束的信令，和/或，所述转发器在所述第二资源不期待收到转发信号。
再例如，所述网络设备不在所述第二资源发送或接收转发信号，和/或，所述网络设备不发送与所述第二资源相关的、动态指示转发的信令，和/或，所述网络设备不发送与所述第二资源相关的、配置/指示转发的信令，和/或，所述网络设备不在所述第二资源发送配置/指示转发波束的信令。
在一些实施例中，所述第二资源通过第三信令被配置。
例如，所述第三信令指示所述第二资源的如下至少之一或任意组合：起始位置、偏移量、周期、结束位置；本申请不限于此，例如还可以指示第二资源的其他属性。
在一些实施例中，所述第二资源能够被另一个第三信令重配置。
例如，如果第二资源被一个半静态信令(RRC信令)配置为不可用资源(OFF资源)，则该第二资源能够被另一个相同的半静态信令(RRC信令)重配置为软资源(灵活资源)或者硬资源(ON资源)或者不可用资源(OFF资源)。
在一些实施例中，所述第三信令和所述第一信令为同一信令。
例如，网络设备可以通过一个信令(例如第一信令)向转发器指示ON状态的第一资源和OFF状态的第二资源。
在一些实施例中，所述第三信令、所述第一信令和所述第二信令为同一信令。
例如，网络设备可以通过一个信令(例如第二信令)为转发器指示第一波束、与该第一波束对应的时域资源即为第一资源、OFF状态的第二资源。
再例如，网络设备可以通过一个信令(例如第一信令)为转发器指示第一资源和第二资源、全部或至少部分第一资源所对应的第一波束。
在一些实施例中，所述第二资源为除了所述第一资源和所述第三资源外的剩余资源。
例如，网络设备可以为转发器配置第一资源(ON资源)和第三资源(灵活资源)，在没有对第二资源明确指示的情况下，除了第一资源和第三资源的其他资源即为第二资源。
在本申请实施例中，处于OFF状态的转发器不转发(或转发器的转发模块不转发)。 例如，转发器不转发是不做以下至少一项：
--在BH链路接收来自基站的信号；
--在AC链路发送经过放大的、在BH链路接收到的信号；
--在AC链路接收信号；
--在BH链路发送经过放大的、在AC链路接收到的信号。
由此，网络设备为转发器配置处于关闭(OFF)状态或者不可用(unavailable)状态的第二资源，可以确保转发器在第二资源所在时间无需转发，进而适当地关闭转发器的部分功能以达到省电目的。如此，既可以减小转发器的能源开销也可以减小整个网络的能源开销，更好地实现低碳环保。
以上对于第二资源或OFF状态等进行了示意性说明，以下再说明第三资源或灵活状态。
在一些实施例中，所述转发器在所述第三资源处于灵活状态或者软(soft)状态。
在一些实施例中，所述第三资源为除了所述第一资源和所述第二资源外的剩余资源。
例如，网络设备可以为转发器配置第一资源(ON资源)和第二资源(OFF资源)，在没有对第三资源明确指示的情况下，除了第一资源和第二资源的其他资源即为第三资源。
在一些实施例中，所述第三资源通过第四信令被配置。
例如，网络设备可以通过第四信令明确指示第三资源。所述第四信令指示所述第三资源的如下至少之一或任意组合：起始位置、偏移量、周期、结束位置；本申请不限于此，还可以指示第三资源的其他属性。
在一些实施例中，所述第四信令和所述第一信令为同一信令。
例如，网络设备可以通过一个信令(例如第一信令)为转发器指示第一资源和第三资源。
在一些实施例中，所述第四信令、所述第一信令和所述第三信令为同一信令。
例如，网络设备可以通过一个信令(例如第一信令)为转发器指示第一资源、第二资源和第三资源。
在一些实施例中，所述第四信令和所述第二信令为同一信令。
例如，网络设备可以通过一个信令(例如第二信令)为转发器指示第一波束和第三资源。
在一些实施例中，所述第四信令和所述第三信令为同一信令。
例如，网络设备可以通过一个信令(例如第三信令)为转发器指示第二资源和第三资源。
在一些实施例中，至少部分第三资源对应的第二波束通过半静态的第五信令被配置/指示，和/或，至少部分第三资源对应的第三波束通过动态的第六信令被配置/指示。
在一些实施例中，所述第五信令指示的第二波束能够被所述第六信令指示的第三波束改写(override)。也就是说，当与第二波束对应的时域资源和与第三波束对应的时域资源至少部分重叠的时候，转发器确定在所述至少部分重叠时域资源使用第三波束进行转发。也即，第六信令的优先级高于第五信令，和/或，第三波束的优先级高于第二波束，和/或，与第三波束对应的第三时域资源优先级高于与第二波束对应的第三时域资源的优先级。
在一些实施例中，根据所述第五信令和/或所述第六信令的优先级，确定所述第三资源对应的波束。例如，在第五信令和第六信令中显式指示该信令的优先级，和/或，由该信令指示的波束的优先级，和/或，由该信令指示的时域资源的优先级。
在一些实施例中，所述第五信令指示的第二波束和/或所述第六信令指示的第三波束所对应的时域资源能够被第七信令指示为关闭(OFF)。
例如，被指示为关闭(OFF)的时域资源不用于转发，或者，被指示为关闭(OFF)的时域资源处于OFF状态或者不可用(unavailable)状态。
在一些实施例中，所述第五信令指示的第二波束能够被指示为关闭(OFF)，和/或，所述第六信令指示的第三波束所对应的时域资源不能够被指示为关闭(OFF)。
在一些实施例中，所述第五信令指示的第二波束能够被另一个第五信令重配(reconfigure)。
在一些实施例中，所述第七信令和所述第六信令为同一信令。
在一些实施例中，所述第六信令通过波束索引的取值指示转发波束。所述第七信令通过某一个波束索引(beam index)和/或其它field的特殊取值指示关闭(OFF)。例如，通过波束索引的一个特殊取值来指示关闭(OFF)，该一个特殊取值为网络设备和转发器预先约定的、预先配置的或者标准预定义的。
在一些实施例中，根据优先级确定所述第五信令指示的第二波束和/或所述第六信令指示的第三波束所对应的时域资源是否能够被指示为关闭(OFF)。
例如，动态信令的优先级高于半静态信令的优先级。
在一些实施例中，在优先级被显式地指示的情况下，根据优先级确定时域资源是否 能够被指示为关闭(OFF)。
例如，在显式指示的优先级相同的情况下，动态信令的优先级高于半静态信令的优先级。再例如，在显式指示的优先级相同的情况下，由所述转发器确定时域资源是否能够被指示为关闭(OFF)。
由此，网络设备为转发器配置处于灵活状态或者软(soft)状态的第三资源，可以增大转发调度的灵活性，并在没有转发需求的时候使得转发器不转发进行减小干扰，提高转发的效率。
在一些实施例中，转发器可以仅支持两种资源，例如网络设备可以为转发器配置第一资源、第二资源、第三资源中的两种。
例如，网络设备可以通过一个信令(例如第一信令)为转发器指示第一资源和第三资源。再例如，网络设备可以通过一个信令(例如第一信令)为转发器指示第一资源，通过另一个信令(例如第四信令)为转发器指示第三资源。以上对于第三资源或灵活状态进行了说明，以下再说明本申请的优先级。
在一些实施例中，转发的优先级可以为以下优先级至少之一或组合
--与该转发相应的转发波束的优先级；
--与该转发相应的配置的优先级；
--承载与该转发相应的配置的信令的优先级；
--与该转发相关的时域资源的优先级；
--与该转发的转发信号的优先级等。
在一些实施例中，半静态信令的优先级高于动态信令的优先级，或者，在后收到的信令的优先级高于在前收到的信令的优先级，或者，动态信令的优先级高于半静态信令的优先级。
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，CSI-RS，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，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。
以上仅示意性对优先级进行了说明，但本申请不限于此。
