Description

转发器的指示方法、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。
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。

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。
发明人认识到，5G系统采用了更高级的MIMO技术，特别是在FR2频段，5G基站能够赋型更窄的波束，并采用波束扫描(beam swiping)服务小区内的终端设备。对于工作在FR1频段的NCR设备，由频段本身特性决定的，网络设备、NCR设备以及被服务的终端设备所支持的波束总数有限。如何基于不同频率范围的无线信号传播特性，对工作在不同频率范围的NCR设备进行设计，以更好地达到省电节能和高效传输的综合效果，成为亟待解决的问题。
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。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，转发器在第一频域范围确定(或默认或被期望)进行转发，除非接收到来自网络设备的第一信息；和/或
502，所述转发器在第二频域范围确定(或默认或被期望)不进行转发，除非接收到来自所述网络设备的第二信息。
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。
在一些实施例中，转发器在第一频域范围转发，除非接收到来自网络设备的第一信息；和/或，所述转发器在第二频域范围不转发，除非接收到来自所述网络设备的第二信息。
例如，如果没有接收到第一信息，转发器在第一频域范围默认具有转发的能力，至于实际上是否转发信号，可以根据实际的调度或指示进行。或者，如果没有收到第一信息，转发器在第一频域范围在已确定的转发频带上按照已经确定的转发方法进行转发。所述已经确定的转发频带和/或已经确定的转发方法可以在出厂前设定、设备安装时设定、由OAM配置和/或由网络设备配置。但本申请不限于此。
再例如，如果没有接收到第二信息，转发器在第二频域范围默认不具有转发的能力，例如转发模块被关闭。或者，如果没有接收到第二信息，转发器在第二频域范围不被允许进行转发或者不实施转发。
在一些实施例中，转发器在第一频域范围被期望(或确定或默认)为开启(ON)，除非接收到来自网络设备的第一信息；和/或，所述转发器在第二频域范围确定(或默认或被期望)为关闭(OFF)，除非接收到来自所述网络设备的第二信息。
在一些实施例中，转发器在第一频域范围被期望(或确定或默认)处于开启(ON)状态，除非接收到来自网络设备的第一信息；和/或，所述转发器在第二频域范围确定(或被默认或被期望)处于关闭(OFF)状态，除非接收到来自所述网络设备的第二信息。
在一些实施例中，转发器在第一频域范围默认(或确定或被期望)进行转发；和/或，转发器在第二频域范围默认(或确定或被期望)不进行转发。
以上示意性对本申请的转发器的一些行为进行了说明，但本申请不限于此，例如以上描述可以相互替换或者相互结合。
在本申请实施例中，转发器在第一频域范围默认(或确定或被期望)进行转发；和/或，转发器在第二频域范围默认(或确定或被期望)不进行转发。由此，能够减少不必要的干扰，提高整个网络的传输效率；此外还能够降低系统功耗和节省能源开销。
在本申请实施例中，在默认的ON状态下，至少转发模块被开启或者开始工作或者能够转发或者转发；在默认的OFF状态下，至少转发模块被关闭或者暂停工作或者停止转发或者不转发。
例如，处于默认ON状态的转发器的转发模块按照已确定的转发波束在已确定的转发频段进行转发；又例如，处于默认ON状态的转发器的转发模块按照已确定的转发波束在已确定的转发频段和已确定的时间进行转发。例如，处于默认的OFF状态的转发器的转发模块停止工作(随时可以开始转发)；又例如，处于默认的OFF状态的转发器中仅转发模块停止工作；又例如，处于默认的OFF状态的转发器中仅转发模块关闭等等。但本申请不限于此。
在一些实施例中，上述转发器被期望(或确定或默认)为开启(ON)可以是所述转发器的转发部件或转发模块(NCR-Fwd)被期望为开启，也可以是转发模块和通信模块均被期望为开启等等。上述转发器被期望(或确定或默认)为关闭(OFF)可以是所述转发器的转发部件或转发模块(NCR-Fwd)被期望为关闭，也可以是转发模块和通信模块均被期望为关闭等等。或者说，转发器的转发模块和通信模块的开启和/或关闭可以一致，也可以不一致。但本申请不限于此。
在一些实施例中，在默认的ON状态下，NCR在FR1在已确定的转发频带上按照已经确定的转发方法进行转发。考虑到FR1的频谱特性以及在FR1部署的网络的特点，使NCR处于这种默认的ON状态有助于节省网络设备的指示开销，提高频谱使用效率，进而增加网络传输速率。
在一些实施例中，在默认的OFF状态下，NCR不对信号进行转发。但是，NCR处于开机或者正常上电的状态，NCR转发模块停止转发。考虑到FR2的频谱特性以及在FR2部署的网络的特点，使NCR处于这种默认的OFF状态的主要目的之一是在网络设备不为NCR所覆盖的终端设备服务的时候，减少NCR对周围设备的不必要的干扰。
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。
在一些实施例中，所述第一频域范围为FR1，所述第二频域范围为FR2；但本申请不限于此。关于FR1和FR2的具体内容可以参考相关技术。例如，第一信息是至少应用于FR1的、至少用于指示OFF的信息；第二信息是至少应用于FR2的、至少用于指示ON的信息。
在一些实施例中，所述第一信息至少用于指示所述转发器暂停转发或不转发或进入/开始/使能关闭(OFF)状态或进入停止转发状态，所述第二信息至少用于指示所述转发器转发或进入/开始/使能开启(ON)状态。
在一些实施例中，所述第一信息至少用于指示转发频率在所述第一频域范围的所述转发器暂停转发或不转发或进入/开始/使能关闭(OFF)状态或进入停止转发状态，所述第二信息至少用于指示转发频域在所述第二频域范围的所述转发器转发或进入/开始/使能开启(ON)状态。
在一些实施例中，所述第一信息至少用于指示转发频率在所述第一频域范围的所述转发器在第一时间暂停转发或不转发或进入/开始/使能关闭(OFF)状态或进入停止转发状态，所述第二信息至少用于指示转发频域在所述第二频域范围的所述转发器在第二时间转发或进入/开始/使能开启(ON)状态。
以下针对至少一个转发频率在第一频率范围(FR1)内的转发器，对第一信息和第一时间进行说明。
在一些实施例中，第一时间默认为转发器进行转发的一段时间。
例如，工作在FR1下的NCR默认在第一时间处于ON状态，除非收到第一信息指示其转为OFF状态或者暂停转发或者指示其在第一时间不转发。
再例如，工作在FR1下的NCR默认处于ON状态，直到该NCR收到来自基站的指示，指示其不转发或者处于OFF状态(例如，通过第一信息)。这种情况下，可以将第一时间理解为第一信息被执行之后的时间段。
再例如，在有基站具体指示之前，工作在FR1下的NCR在某一个时间(例如，第一时间)默认处于ON状态。除非NCR在该第一时间之前收到了来自基站的第一信息，指示其在该第一时间不转发或者指示其在第一时间为OFF状态，NCR在第一时间处于ON状态。
在一些实施例中，所述转发器接收用于指示转发器至少在所述第一时间不转发的第一信息，所述转发器的至少一个转发频率在所述第一频域范围。所述转发器根据所述第一信息在所述第一时间不转发。
在一些实施例中，所述转发器根据所述第一信息能够在所述第一时间不转发。
例如，在没有其他信息指示的情况下，转发器根据第一信息在第一时间不转发。再例如，在还接收到其他信息且该其他信息的优先级高于第一信息或者该其他信息改写了第一信息的指示的情况下，转发器至少根据该其他信息在第一时间转发或者不转发。
在一些实施例中，转发器在第一时间之前未接收到第一信息的情况下，在所述第一时间进行转发。
在一些实施例中，转发器在第一时间之前接收到第一信息的情况下，在所述第一时间不转发。
在一些实施例中，所述第一时间可以由所述第一信息指示。
在一些实施例中，所述第一时间为非周期性的一段时间；所述第一信息还指示所述第一时间的如下至少之一：起始时间点、结束时间点、持续时长。
在一些实施例中，所述第一时间为周期性的一段时间；所述第一信息还指示所述第一时间的如下至少之一：周期、偏移量、起始时间点、结束时间点、持续时长。
在一些实施例中，第一信息可以显式指示第一时间。
例如，第一信息可以显式指示一个时间段，该时间段至少包含第一时间；该时间段可以是周期性的。第一信息可以指示周期和偏移量，和/或，起始时间和持续时间。
再例如，一个第一信息可以指示一个时间点，该时间段从该时间点开始，直至基站指示结束为止。该时间段的结束时间点可以由另一个第一信息指示，也可以由其它信息指示。
在一些实施例中，第一信息可以隐式指示第一时间。
例如，第一信息也可以隐式指示一个时间段，该时间段至少包含第一时间。例如，第一信息为NCR-MT的DRX指示，第一时间为NCR-MT的休眠时间。例如，第一信息为功率指示信息，指示NCR Fwd的转发功率在第一时间为零。
在又一些实施例中，所述第一时间由转发器根据其它信息和/或预定义规则确定。例如，转发器确定转发器通信模块的关闭时间为所述第一时间，或者，根据高层定时器确定第一时间的起始和/或终止等等。
图6是本申请实施例的第一信息和第一时间的一示例图。如图6的上半部分所示，如果NCR在第一时间之前没有收到第一信息，NCR在该第一时间处于ON状态，NCR在该第一时间进行转发。如图6的下半部分所示，如果NCR在第一时间之前收到了来自基站的第一信息，指示其在该第一时间不转发，则NCR确定在该第一时间根据该第一信息不转发(如图6中的OFF所示)。
在一些实施例中，第一信息可以指示转发器在周期性的第一时间不转发。
图7是本申请实施例的第一信息和第一时间的另一示例图。如图7所示，在接收到基站发送的第一信息之后，转发器可以在周期性的第一时间不转发(如OFF所示)，在 其他时间进行转发(如ON所示)。
在一些实施例中，第一信息可以指示周期性的第一时间不转发(如OFF所示)和指示周期性的ON时间。
图8是本申请实施例的第一信息和第一时间的另一示例图。如图8所示，该第一信息指示ON/OFF时间，NCR按照第一信息在周期性的第一时间不转发，或者，NCR在周期性的第一时间转为OFF状态，NCR按照第一信息在周期性的第五时间转发，或者，NCR在周期性的第五时间转发为ON状态。图8所示第一时间位于第五时间之前。在具体实施中，第一时间也可以位于第五时间之后。本申请不以此为限制。
例如，当该NCR服务的终端设备数据量不大的时候，基站可以指示NCR周期性地转发和不转发。在这种周期性的时间里，当NCR不进行转发的时候，可以适当关闭转发部件以及相应的控制部件，以便达到更好的节能效果。指示周期性ON/OFF的第一信息，可以由动态信令承载也可以由半静态信令承载。
在一些实施例中，所述转发器在所述第一时间之前的N个符号和/或M个时隙还未接收到所述第一信息的情况下，在所述第一时间进行转发；N和M均为大于或等于0的整数。
例如，在第一时间之前定义最小间隔(interval/gap)或者最小处理时延。
图9是本申请实施例的第一信息和第一时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图9中所示的第一间隔。如图9所示，如果NCR(NCR-MT)在第一时间开始前的第一间隔之前收到第一信息，NCR-Fwd按照第一信息不转发，或者，NCR-Fwd转为OFF状态。
也就是说，第一信息的到达时刻与第一时间的起始时刻之间大于或等于最小间隔，NCR在第一时间为OFF。
图10是本申请实施例的第一信息和第一时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图10中所示的第一间隔。如图10所示，如果NCR(NCR-MT)在第一时间开始前的第一间隔之内收到第一信息，NCR-Fwd不按照第一信息指示不转发，或者，NCR-Fwd不转为OFF状态。
也就是说，第一信息的到达时刻与第一时间的起始时刻之间小于最小间隔，NCR不执行第一信息的指示，即NCR在第一时间仍为ON。
图11是本申请实施例的第一信息和第一时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图11中所示的第一间隔。如图11所示，如果NCR(NCR-MT) 在第一时间开始前的第一间隔之前收到第一信息，NCR-Fwd按照第一信息不转发，或者，NCR-Fwd在第一时间转为OFF状态。
图12是本申请实施例的第一信息和第一时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图12中所示的第一间隔。如图12所示，如果NCR(NCR-MT)在第一时间开始前的第一间隔之前收到第一信息，NCR-Fwd按照第一信息在周期性的第一时间不转发，或者，NCR-Fwd在周期性的第一时间转为OFF状态。
由此，定义或规定最小时间间隔有助于规范终端设备和基站的实现，为不同厂商的基站设备和终端设备联合调试提供便利，由此加快产品更新换代为市场提供更快更好的服务。
图13是本申请实施例的第一信息和第一时间的另一示例图。如图13所示，可以没有最小间隔的要求。在这种情况下，可以由基站保证：第一信息的到达时刻与第一时间的起始时刻之间的间隔足够NCR-MT对接收到的第一信息进行解调/解码以及NCR-Fwd准备执行第一信息所指示的不转发或者进入所指示的OFF状态。
由此，由基站保证信息的接收和信息所指示内容的执行之间的时间间隔，有助于为基站产品和终端产品的实现提供更大的自由度。对于硬件计算能力强、算法先进的设备，如此可以允许其发挥最大能力，使得采用该设备部署的网络处理时延减小、有效传输时间增加，进而提高该网络的传输效率。
在一些实施例中，第一信息指示从第一时间点开始的包括所述第一时间的一段时间内所述转发器不能够转发。所述第一时间为从第一时间点开始的一段时间。
图14是本申请实施例的第一信息和第一时间的另一示例图。如图14所示，如果NCR(NCR-MT)在第一时间开始前收到第一信息，NCR-Fwd按照第一信息的指示在第一时间点开始进入OFF状态，即不能够进行转发。
在一些实施例中，所述转发器还可以接收第三信息；以及所述转发器根据所述第三信息从第三时间点开始转发。
图15是本申请实施例的第一信息和第一时间的另一示例图。如图15所示，如果NCR(NCR-MT)在第一时间开始前收到第一信息，NCR-Fwd按照第一信息的指示在第一时间点开始进入OFF状态，即不能够进行转发。如果NCR(NCR-MT)在第一时间点之后收到第三信息，NCR-Fwd按照第三信息的指示在第三时间点开始进入ON状态，即能够进行转发。
在一些实施例中，第一信息可以是显式信息(explicit information)，也可以是隐式信 息(implicit information)。
例如，显式的第一信息可以用于指示NCR在第一时间点进入OFF状态，如图14和15所示。再例如，显式的第一信息可以用于指示NCR在第一时间进入(或处于)OFF状态，如图6和11所示。再例如，显式的第一信息可以用于指示NCR在第一时间不转发。
在一些实施例中，所述第一信息为动态信令和/或半静态信令。
在一些实施例中，所述第一信息由物理下行控制信道(PDCCH)和/或MAC CE和/或无线资源控制(RRC)信令承载。
例如，第一信息可以是用于动态指示NCR不转发的信息。
--例如，第一信息可以是DCI，指示NCR不转发；例如，第一信息可以是专用信令，指示NCR不转发；再例如，第一信息可以重用用于指示NCR转发的信令(该信令至少应用于FR2)，例如预定义一个field的固定取值，以此指示NCR不转发，如果工作在FR1的NCR收到该信令，且该field取值为预先约定的固定值，则该NCR在该信令相应的第一时间不转发。再例如，第一信息可以重用用于指示NCR转发波束的信令(该信令至少应用于FR2)，通过最小或最大波束序号或者预定义的波束序号指示NCR不转发，则该工作在FR1的NCR在这些波束相应的第一时间不转发等等。
--又例如，第一信息可以是DCI，指示NCR功率；其中，如果被指示的功率为零，NCR接收到该DCI后，在与第一信息相应的第一时间不转发；
--还例如，第一信息指示某一灵活时间单位仍为灵活时间单位，NCR在该灵活时间单位不转发。
再例如，第一信息还可以是半静态/半持续信息，至少用于指示NCR不转发。
--例如，第一信息用于半静态地指示NCR处于OFF的时间，该OFF时间(第一时间)可以是周期性的或者非周期的。
--又例如，第一信息用于半静态/半持续指示NCR不转发的时间。例如，基站为UE配置了DRX模式，在终端设备处于休眠时间的时候，相应地NCR不转发。
--还例如，第一信息为半静态信息，指示NCR周期性的转发(ON)时间和不转发(OFF)时间。
在一些实施例中，上述半静态的第一信息可以通过MAC CE或者RRC信令指示/承载。在另一些实施例中，上述半持续的第一信息可以通过MAC CE或者RRC先配置一种或者大于一种的配置信息，随后通过DCI或者MAC CE或者其它信号激活其中的一 种或者几种。
以下针对至少一个转发频率在第二频率范围(FR2)内的转发器，对第二信息和第二时间进行说明。
在一些实施例中，第二时间默认为转发器不进行转发的一段时间。
例如，工作在FR2的NCR默认在第二时间处于OFF状态，除非收到第二信息指示其转为ON状态或者指示其在第二时间进行转发。由于这种OFF状态下的转发器可以随时被第二信息指示而变更为ON状态，这种默认的OFF状态可以是一种动态OFF状态。由此，采用动态OFF状态，可以根据网络设备的实时调度，及时地调整转发器的状态(转发或者不转发)。
再例如，工作在FR2的NCR默认处于OFF状态，直到该NCR收到来自基站的指示，指示其进行转发或者处于ON状态(例如，通过第二信息)。
再例如，在有基站具体指示之前，工作在FR2的NCR在某一个时间(例如，第二时间)默认处于OFF状态。除非NCR在该第二时间之前收到了来自基站的第二信息，指示其在该第二时间进行转发或者指示其在第二时间为ON状态，NCR在第二时间处于OFF状态。
在一些实施例中，所述转发器接收用于指示所述转发器至少在所述第二时间转发的第二信息，所述转发器的至少一个转发频率在所述第二频域范围。所述转发器根据所述第二信息在所述第二时间进行转发。
在一些实施例中，所述转发器根据所述第二信息能够在所述第二时间转发。
例如，在没有其他信息指示的情况下，转发器根据第二信息在第二时间进行转发。再例如，在还接收到其他信息且该其他信息的优先级高于第二信息或者该其他信息改写了第二信息的指示的情况下，转发器根据该其他信息在第二时间不转发或者转发。
在一些实施例中，转发器在第二时间之前未接收到第二信息的情况下，在所述第二时间不进行转发。
在一些实施例中，转发器在第二时间之前接收到第二信息的情况下，在所述第二时间进行转发。
在一些实施例中，所述第二时间可以由所述第二信息指示。
在一些实施例中，所述第二时间为非周期性的一段时间；所述第二信息还指示所述第二时间的如下至少之一：起始时间点、结束时间点、持续时长。
在一些实施例中，所述第二时间为周期性的一段时间；所述第二信息还指示所述第 二时间的如下至少之一：周期、偏移量、起始时间点、结束时间点、持续时长。
在一些实施例中，第二信息可以显式地指示第二时间。
例如，第二信息可以显式指示一个时间段，该时间段至少包含第二时间；该时间段可以是周期性的。第二信息可以指示周期和偏移量，和/或，起始时间和持续时间。
再例如，一个第二信息可以指示一个时间点，该时间段从该时间点开始，直至基站指示结束为止。该时间段的结束时间点可以由另一个第二信息指示，也可以由其它信息指示。
在一些实施例中，第二信息可以隐式地指示第二时间。
例如，第二信息也可以隐式指示一个时间段，该时间段至少包含第二时间。例如，第二信息为NCR-MT的DRX指示，第二时间为NCR-MT的开启时间。例如，第二信息为功率指示信息，指示NCR Fwd的转发功率在第一时间为非零。
在又一些实施例中，所述第二时间由转发器根据其它信息和/或预定义规则确定。例如，转发器确定转发器通信模块的开启时间为所述第二时间，或者，根据高层定时器确定第二时间的起始和/或终止等等。
图16是本申请实施例的第二信息和第二时间的一示例图。如图16的上半部分所示，如果NCR在第二时间之前没有收到第二信息，NCR在该第二时间处于OFF状态，NCR在该第二时间不进行转发。如图16的下半部分所示，如果NCR在第二时间之前收到了来自基站的第二信息，指示其在该第二时间进行转发，则NCR确定在该第二时间根据该第二信息进行转发(如图16中的ON所示)。
在一些实施例中，第二信息可以指示转发器在周期性的第二时间进行转发。
图17是本申请实施例的第二信息和第二时间的另一示例图。如图17所示，在接收到基站发送的第二信息之后，转发器可以在周期性的第二时间进行转发(如ON所示)，在其他时间不进行转发(如OFF所示)。
在一些实施例中，第二信息除指示周期性的第二时间转发(如ON所示)以外，还可以指示周期性的OFF时间
图18是本申请实施例的第二信息和第二时间的另一示例图。如图18所示，该第二信息指示ON/OFF时间，NCR按照第二信息在周期性的第二时间转发，或者，NCR在周期性的第二时间转为ON状态，或者，NCR按照第二信息在周期性的第六时间不转发，或者，NCR在周期性的第六时间转发为OFF状态。图18所示第二时间位于第六时间之前。在具体实施中，第二时间也可以位于第六时间之后。本申请不以此为限制。
例如，当该NCR服务的终端设备数据量不大的时候，基站可以指示NCR周期性地转发和不转发。在这种周期性的时间里，当NCR不进行转发的时候，可以适当关闭转发部件以及相应的控制部件，以便达到更好的节能效果。指示周期性ON/OFF的第二信息，可以由动态信令承载也可以由半静态信令承载。
在一些实施例中，图8所示的应用于FR1的ON/FF指示与图18所示的应用于FR2的ON/OFF指示由同一信令指示。接收到该信令后，NCR根据其转发频带在FR1或者FR2按照该信令所指示的时间(和转发方式等)进行转发或者不转发。通过一个信令进行指示，能够简化系统设计和产品实现。
在又一些实施例中，图8所示的应用于FR1的ON/FF指示与图18所示的应用于FR2的ON/OFF指示可以由不同信令指示。例如，NCR接收到应用于FR1的信令时，按照该信令所指示的时间(和转发方式等)在其位于FR1的转发频带进行转发或者不转发；NCR接收到应用于FR2的信令时，按照该信令所指示的时间(和转发方式等)在其位于FR2的转发频带进行转发或者不转发。通过不同信令指示应用于FR1和FR2的转发时间和/或转发行为，有助于简化产品实现逻辑。此外，通过不同信令指示应用于FR1和FR2的转发时间和/或转发行为，还有助于支持高级NCR的实现，例如一个NCR设备可以同时有多个转发频带，其中一部分位于FR1另外一部分位于FR2。
在一些实施例中，所述转发器在所述第二时间之前的N个符号和/或M个时隙还未接收到所述第二信息的情况下，在所述第二时间不进行转发；N和M均为大于或等于0的整数。
例如，在第二时间之前定义最小间隔(interval/gap)或者最小处理时延。
图19是本申请实施例的第二信息和第二时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图19中所示的第二间隔。如图19所示，如果NCR(NCR-MT)在第二时间开始前的第二间隔之前收到第二信息，NCR-Fwd在第二时间按照第二信息进行转发，或者，NCR-Fwd在第二时间转为ON状态。
也就是说，第二信息的到达时刻与第二时间的起始时刻之间大于或等于最小间隔，NCR在第二时间为ON。
图20是本申请实施例的第二信息和第二时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图20中所示的第二间隔。如图20所示，如果NCR(NCR-MT)在第二时间开始前的第二间隔之内收到第二信息，NCR-Fwd不按照第二信息指示进行转发，或者，NCR-Fwd不转为ON状态。
也就是说，第二信息的到达时刻与第二时间的起始时刻之间小于最小间隔，NCR不执行第二信息的指示，即NCR在第二时间仍为OFF。
图21是本申请实施例的第二信息和第二时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图21中所示的第二间隔。如图21所示，如果NCR(NCR-MT)在第二时间开始前的第二间隔之前收到第二信息，NCR-Fwd按照第二信息进行转发，或者，NCR-Fwd转为ON状态。
图22是本申请实施例的第二信息和第二时间的另一示例图。例如，标准预定义最小间隔或最小处理时延，即图22中所示的第二间隔。如图22所示，如果NCR(NCR-MT)在第二时间开始前的第二间隔之前收到第二信息，NCR-Fwd按照第二信息在周期性的第二时间进行转发，或者，NCR-Fwd在周期性的第二时间转为ON状态。
由此，定义或规定最小时间间隔有助于规范终端设备和基站的实现，为不同厂商的基站设备和终端设备联合调试提供便利，由此加快产品更新换代为市场提供更快更好的服务。
图23是本申请实施例的第二信息和第二时间的另一示例图。如图23所示，可以没有最小间隔的要求。在这种情况下，可以由基站保证：第二信息的到达时刻与第二时间的起始时刻之间的间隔足够NCR-MT对接收到的第二信息进行解调/解码以及NCR-Fwd准备执行第二信息所指示的转发或者进入所指示的ON状态。
由此，由基站保证信息的接收和信息所指示内容的执行之间的时间间隔，有助于为基站产品和终端产品的实现提供更大的自由度。对于硬件计算能力强、算法先进的设备，如此可以允许其发挥最大能力，使得采用该设备部署的网络处理时延减小、有效传输时间增加，进而提高该网络的传输效率。
在一些实施例中，第二信息指示从第二时间点开始的包括所述第二时间的一段时间内所述转发器能够进行转发。
图24是本申请实施例的第二信息和第二时间的另一示例图。如图24所示，如果NCR(NCR-MT)在第二时间开始前收到第二信息，NCR-Fwd按照第二信息的指示在第二时间点开始进入ON状态，即能够进行转发。
在一些实施例中，所述转发器还可以接收第四信息；以及所述转发器根据所述第四信息从第四时间点开始不能够转发。
图25是本申请实施例的第二信息和第二时间的另一示例图。如图25所示，如果NCR(NCR-MT)在第二时间开始前收到第二信息，NCR-Fwd按照第二信息的指示在第二 时间点开始进入ON状态，即能够进行转发。如果NCR(NCR-MT)在第二时间点之后收到第四信息，NCR-Fwd按照第四信息的指示在第四时间点开始进入OFF状态，即不能够进行转发。
在一些实施例中，第二信息还指示所述转发器所使用的转发波束。例如，被指示的所述转发波束为接入(AC)链路上的波束和/或反馈(backhaul)链路上的波束。
在一些实施例中，第二信息还指示所述转发器进行转发。所述转发器使用默认波束。所述默认波束可以是预先约定的波束，也可以是转发器采用的默认波束。例如，转发器在反馈链路可以采用默认波束。采用默认波束有助于节省指示信息开销，提高有效数据传输效率。
在一些实施例中，第二时间包括灵活时间单位。第二信息用于指示所述第二时间中所包括的灵活时间单位为上行时间单位，和/或，所述第二信息用于指示所述第二时间中所包括的灵活时间单位为下行时间单位。第二信息指示所述第二时间中所包括的灵活时间单位为上行时间单位，所述转发器在所述被指示为上行时间单位的第二时间将其在接入链路接收到的信号通过反馈链路向网络设备转发。第二信息指示所述第二时间中所包括的灵活时间单位为下行时间单位，所述转发器在所述被指示为下行时间单位的第二时间将其在反馈链路接收到的、来自网络设备的信号通过接入链路转发出去。
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。
在一些实施例中，第二信息指示NCR功率，该功率非零，NCR在第二时间使用该功率进行转发。
在一些实施例中，第二信息可以是显式信息(explicit information)，也可以是隐式信息(implicit information)。
例如，显式的第二信息可以用于指示NCR在第二时间点进入ON状态，如图24和25所示。再例如，显式的第二信息可以用于指示NCR在第二时间进入(或处于)ON状态，如图17和21所示。再例如，显式的第二信息可以用于指示NCR在第二时间进行转发(例如使用默认波束)，如图17和21所示。
再例如，隐式的第二信息可以用于指示NCR使用的转发波束，所述被指示的转发波束为AC链路的波束和/或反馈链路的波束。NCR在第二时间使用所述第二信息指示的波束进行转发。
又例如，隐式的第二信息可以用于向NCR指示第二时间的灵活单位为上行时间单 位还是下行时间单位。NCR在上行时间单位进行从接入链路到反馈链路的转发，在下行时间单位进行从反馈链路到接入链路的转发。
在一些实施例中，所述第二信息为动态信令或者半静态信令。
在一些实施例中，所述第二信息由物理下行控制信道(PDCCH)和/或MAC CE和/或无线资源控制(RRC)信令承载。
例如，第二信息可以是用于动态指示NCR进行转发的信息。
--例如，第二信息动态地指示使用默认波束进行转发，默认波束可以由通信标准预定义，也可以由OAM进行配置，还可以由网络设备指示或者确认。
--例如，第二信息动态地指示NCR与第二时间对应的转发波束，NCR在第二时间结束OFF状态，使用该指示的波束进行转发。
--又例如，第二信息动态地指示NCR功率，该功率非零，NCR在第二时间使用该功率进行转发。
--还例如，第二信息动态地指示灵活时间单位为上行时间单位和/或下行时间单位，NCR在所述上行时间单位将从接入链路接收的信号在反馈链路转发，在所述下行时间单位将在反馈链路接收到的信号在接入链路转发。
再例如，第二信息还可以是半静态指示NCR进行转发的半静态(半持续)信息。
--例如，第二信息用于半静态地指示NCR处于ON的时间。
--又例如，第二信息用于半静态/半持续指示NCR进行转发的时间和/或所使用的波束。例如，为了所服务的终端设备的半持续数据传输，基站通过第二信息半静态/半持续地配置NCR对该数据进行转发。这种配置可以用于参考信号转发，例如CSI-RS和SRS等。基站可以仅配置NCR转发方法，而不指示该配置用途。
--又例如，第二信息用于半静态/半持续指示NCR进行转发的时间和/或所使用的波束。例如，转发用于终端设备接入小区或者保持与基站连接等作用的公共信号。
在一些实施例中，上述半静态的第二信息通过MAC CE或者RRC指示。在另一些实施例中，上述半持续的第二信息通过MAC CE或者RRC先配置一种或者大于一种的配置信息，随后通过DCI或者MAC CE或者其它信号激活其中的一种或者几种。
以上示意性说明第一信息和第二信息的情况，但本申请不限于此，还可以将上述的各个实施例结合起来。
例如，NCR在FR1默认处于ON，在FR2默认处于OFF。用于指示周期性ON/OFF的第一信息和第二信息可以是一个信息。该信息可以既指示ON又指示OFF。由此，可 以节省信令设计所需要的标准化时间，加快标准化协议冻结，加速产业升级。同时，还可以节省协议栈存储空间从而降低设备成本。
在上述实施例中，考虑了部署在不同频段范围的5G网络的工作特点。在FR1频段，基站用于服务终端设备的波束较FR2频段的宽，基站可以用较少的波束覆盖其所覆盖的区域。相应地，处于FR1频段的终端设备在网络设备通过波束扫描提供服务的时候有较多被服务的机会。
在本申请实施例中，在FR1频段进行转发的NCR默认处于ON状态，在收到第一信息时进入OFF状态。相较于默认处于OFF状态，基站可以用较少的第一信息控制NCR完成在FR1所需要的转发。
而在FR2频段进行转发的NCR默认处于OFF状态，在收到第二信息的时候进入ON状态。相较于默认处于ON状态，基站可以用较少的第二信息控制NCR完成在FR2所需要的转发。
因此，采用本申请的实施方案，既可以在不需要转发的时候使NCR处于不转发状态以达到节电目的，又可以根据频段部署特性利用较少的控制信息达到控制NCR转发或者不转发的效果，降低了控制信息的发送频率并提高了信息传输效率，从而更好地取得省电节能和高效传输的综合效果。
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，转发器默认(或确定或被期望)在第一频域范围进行转发，和/或，转发器默认(或确定或被期望)在第二频域范围不进行转发。由此，能够减少不必要的干扰，提高整个网络的传输效率；此外还能够降低系统功耗和节省能源开销。
