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.

  • the NCR can suspend forwarding signals by using the implementation method of the present application, thereby reducing interference to other surrounding devices, improving the transmission signal-to-noise ratio of other devices, and thus improving the throughput of the entire network.
  • the main function of NCR is to enhance the signal coverage of certain areas of the cell. Relatively speaking, the coverage area of NCR is small, so there is a situation where there is no terminal device that needs to be served in the area covered by NCR for a period of time (for example, there is no terminal device in the RRC connection state, or no terminal device has service transmission requirements, or there is no terminal device in the coverage area of NCR).

  • 5G base stations serve terminal devices through beams.
  • the beams of 5G base stations are usually narrower than those of 4G and 3G base stations (due to the high operating frequency and the use of advanced MIMO technology). Therefore, it is impossible for the beams of 5G base stations to always point to a certain NCR.

  • the NCR is in the OFF state by default at the first time, unless it receives the first information instructing it to turn to the ON state or instructing it to forward at the first time.

Abstract

本申请实施例提供了一种转发器的指示方法、转发器和网络设备。所述方法包括：转发器确定(或默认或被期望)在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。

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。
发明内容
针对上述问题的至少之一，本申请实施例提供了一种转发器的指示方法、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)，此外还能够降低系统功耗和节省能源开销。
根据本申请实施例的一方面，提供一种转发器的指示方法，包括：
转发器确定在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及
所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。
根据本申请实施例的另一方面，提供一种转发器，包括：
确定单元，其确定在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及
接收单元，其接收用于指示所述转发器在所述第一时间不进行转发的第二信息。
根据本申请实施例的另一方面，提供一种转发器的指示方法，包括：
网络设备向转发器发送第一信息；其中，转发器确定在第一时间不进行转发，除非接收到所述第一信息；以及
所述网络设备向所述转发器发送用于指示所述转发器在所述第一时间不进行转发的第二信息。
根据本申请实施例的另一方面，提供一种网络设备，包括：
第一发送单元，其向转发器发送第一信息；其中，转发器确定在第一时间不进行转发，除非接收到所述第一信息；以及
第二发送单元，其向所述转发器发送用于指示所述转发器在所述第一时间不进行转发的第二信息。
根据本申请实施例的另一方面，提供一种通信系统，包括：
网络设备，其向转发器发送第一信息和/或第二信息；以及
转发器，其确定在第一时间不进行转发，除非接收到所述第一信息；以及接收用于指示所述转发器在所述第一时间不进行转发的所述第二信息。
本申请实施例的有益效果之一在于：转发器确定(或默认或被期望)在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。由此，转发器默认在第一时间为OFF，从而能够减少不必要的干扰，提高整个网络的传输效率；此外在收到第二信息的情况下转发器被指示在第一时间为OFF，从而还能够降低系统功耗和节省能源开销。

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，转发器确定(或默认或被期望)在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及
502，所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。
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，转发器被期望(或确定或默认)为关闭(OFF)，除非接收到来自网络设备的第一信息(显式地指示或者隐式地指示)；以及所述转发器接收用于指示所述转发器不进行转发的第二信息。
在一些实施例中，转发器被期望(或确定或默认)在第一时间处于关闭(OFF)状态，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。
在一些实施例中，转发器确定(默认或被期望)在第一时间不进行转发；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。
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，发明人认识到，例如5G系统采用了更高级的MIMO技术，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，也即基站可以在不同时间使用不同空间方向的波束服务处于小区覆盖范围内不同 地理位置的终端设备。5G基站几乎不会一直服务NCR覆盖的终端设备，当5G基站不服务NCR覆盖的设备的时候，采用本申请的实施方式，NCR可以暂停转发信号，以此减小对周围其它设备的干扰，提高其它设备的传输信噪比，进而提升整个网络的吞吐量。
此外，NCR的主要作用是增强小区的某些区域的信号覆盖，相对而言NCR的覆盖面积较小，因此存在NCR所覆盖的区域在一段时间内没有需要服务的终端设备的情况(例如，没有处于RRC连接态的终端设备，或者，没有终端设备有业务传输需求，又或者，在NCR的覆盖范围里没有终端设备)。这种情况下，基站可以指示NCR进入休眠/睡眠状态，以节省NCR设备耗电。
在本申请实施例中，为了方便说明，可以将NCR在第一时间默认的OFF状态称为默认的OFF状态，由第二信息指示的OFF状态称为指示的OFF状态。处于默认的OFF状态和指示的OFF状态的转发器的行为可以相同，例如转发模块(转发器)被关闭或者暂停工作或者停止转发或者不转发。处于默认的OFF状态和转发的OFF状态的转发器的行为也可以不同，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)，而处于指示的OFF状态的转发器的转发模块处于休眠状态或者关闭状态(需要一定的时延进入转发状态)。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，而处于指示的OFF状态的转发器中转发模块处于休眠状态或者转发模块和通信模块(NCR-MT)均处于休眠状态。又例如，处于默认的OFF状态的转发器中仅转发模块关闭，而处于指示的OFF状态的转发器转发模块和通信模块均处于关闭状态等等。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。但本申请不限于此。
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。使NCR处于这种OFF状态的主要目的是减少NCR对周围设备的不必要的干扰。
例如，5G基站通过波束来服务终端设备，5G基站的波束通常比4G和3G基站的窄(由于工作频率高和高级MIMO技术的采用)，因此，5G基站的波束不可能总指向某一NCR。换句话说，5G基站利用beam swiping通常在不同的时间来服务不同 方向的终端设备。5G基站不可能一直服务该NCR下的终端设备。在5G基站服务其它方向终端设备的时候，NCR可以处于默认的OFF状态下。没有与基站通信的信号交互的时候，NCR不进行转发。这一点与RF repeater不同，RF repeater总是处于开机状态，不区分(也基本没有能力区分)是否有信号交互发生在基站和其所服务的终端设备之间，仅仅是将收到的信号放大再发送出去。因此，RF repeater在没有被基站指向的时候，会放大不必要的信号，进而产生不必要的干扰。
在一些实施例中，在指示的OFF状态下，NCR也不对信号进行转发，可以进入一定程度的休眠。使NCR处于这种的OFF状态的主要目的是省电。
例如，当NCR所覆盖的区域内没有终端设备，或者没有需要被服务的终端设备，基站可以为NCR配置OFF状态。
在本申请实施例中，转发器确定(或默认或被期望)在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。由此，转发器默认在第一时间为OFF(处于默认的OFF状态)，从而能够减少不必要的干扰，提高整个网络的传输效率；此外在收到第二信息的情况下转发器被指示在第一时间为OFF(处于指示的OFF状态)，从而还能够降低系统功耗和节省能源开销。
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，第一时间被默认为转发器不进行转发的一段时间。
例如，NCR默认在第一时间处于OFF状态，除非收到第一信息指示其转为ON状态或者指示其在第一时间进行转发。由于这种OFF状态下的转发器可以随时被第一信息指示而变更为ON状态(转发状态)，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，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，通过第一信息)。这种情况下，可以将第一时间理解为接收到第一信息之前或者第一信息被执行之前的时间段。
再例如，在有基站具体指示之前，NCR在某一个时间(例如，第一时间)默认处于OFF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进行转发或者指示其在第一时间为ON状态，NCR在第一时间处于默认的OFF状态。
在一些实施例中，转发器接收用于指示所述转发器至少在第一时间进行转发的第一信息，所述转发器根据所述第一信息在所述第一时间进行转发。
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进行转发。
例如，在没有其他信息指示的情况下，转发器至少根据第一信息在第一时间进行转发。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一信息的情况下或者该其它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，在所述第一时间不进行转发。
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，在所述第一时间进行转发。
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，第一信息可以是显式指示第一时间，也可以是隐式指示第一时间。
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。
又例如，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，所述第一时间由转发器根据其它信息和/或预定义规则确定。
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在该第一时间默认处于OFF状态，NCR在该第一时间不进行转发。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进行转发，则NCR确定在该第一时间根据该第一信息进行转发(如图6中的ON所示)。
在一些实施例中，转发器还接收第二信息，指示该转发器在第二时间为OFF状态。进一步地，所述第二信息指示所述转发器在第二时间为OFF状态，所述第二时间包含所述第一时间。所述第二时间可以是一段时间，也可以是多段时间；可以是周期性的时间段，也可以是非周期性的时间段。
在一些实施例中，所述包括所述第一时间的第二时间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，第二信息可以是显式信息(explicit information)，也可以是隐式信息(implicit information)。
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一时间；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。
又例如，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的休眠时间。例如，第二信息为功率指示信息，指示NCR Fwd的转发功率在第二时间为零。
在又一些实施例中，所述包括所述第一时间的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休眠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7是本申请实施例的第二信息和第二时间的一示例图。如图7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不进行转发(OFF)。NCR确定在该第二时间不转发。
以上示意性说明了第一信息和第一时间的关系，以及第二信息和第二时间的关系。本申请不限于此，此外，第一时间和/或第二时间可以是周期性的。
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进行转发。
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，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进行转发(如ON所示)。可选地，该第一信息还可以指示转发器在其他时间不进行转发(如OFF所示)。
在一些实施例中，第二信息可以指示转发器在周期性的第二时间不转发。
图9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9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不转发，例如进入休眠状态。
在一些实施例中，第二信息还可以指示转发器进行转发(ON)，该ON状态可以称为暂定的ON状态，而由第一信息指示的ON状态称为指示的ON状态。
图10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10所示，第二信息可以配置ON/OFF。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不转发(如OFF所示)，例如进入休眠状态。对于暂定的ON状态，在接收到第一信息的指示后，转发器才能够转发。又例如，在第二信息指示的暂定的ON状态时，转发器默认处于OFF状态，除非接收到第一信息。
在一些实施例中，可以为第一信息和第二信息设置间隔时间。
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，在所述第一时间不进行转发；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 信息进行转发，或者，NCR-Fwd转为ON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ON。
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内收到第一信息，NCR-Fwd不按照第一信息指示进行转发，或者，NCR-Fwd不转为ON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OFF。
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。例如，标准预定义最小间隔或最小处理时延，即图13中所示的第一间隔。如图13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按照第一信息进行转发，或者，NCR-Fwd转为ON状态。
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。例如，标准预定义最小间隔或最小处理时延，即图14中所示的第一间隔。如图14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进行转发，或者，NCR-Fwd在周期性的第一时间转为ON状态。
在一些实施例中，在第二时间之前定义最小间隔(interval/gap)或者最小处理时延。第一时间之前的最小间隔与第二时间之前的最小间隔可以相同，或者也可以不同。
图15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15中所示的第二间隔。如图15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按照第二信息不转发；否则可以忽略该第二信息。
图16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16中所示的第二间隔。如图16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不转发；否则可以忽略该第二信息。
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17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17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转发或者进入所指示的ON状态。
图17以第一信息和第一时间为例进行了说明，类似地，第二信息和第二时间也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一段时间内所述转发器能够进行转发。所述第一时间为从第一时间点开始的一段时间。
图18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18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ON状态，即能够进行转发。这种情况下，第一时间可以是该第一时间点之后的一段时间。
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不转发或者不根据所述第一信息进行转发。
图19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19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ON状态，即能够进行转发。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OFF状态，即不进行转发。这种情况下，第一时间可以是该第一时间点和第三时间点之间的一段时间。
在一些实施例中，所述第二信息指示从第二时间点开始的一段时间内所述转发器 不能够进行转发。
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。如图20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OFF状态(指示的OFF状态)，例如进入休眠状态。
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默认不转发。
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。如图21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OFF状态(指示的OFF状态)。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(默认的OFF状态)。
以下再对第一信息和/或第一时间进行进一步说明。
在一些实施例中，第一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，第一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。
又例如，转发器在FR1(Frequency range1)可以在反馈链路和/或接入链路采用固定波束。或者，转发器被配置和/或设置在FR1进行转发，网络设备不向转发器指示转发波束，转发器自行决定转发波束或者采用固定转发波束。又或者，OAM或网络设备为转发器预先配置/指示默认转发波束。第一信息指示转发器进行转发或者指示转发器处于(或者进入)ON状态。或者，第一信息指示转发器在第一时间进行转发或者在第一时间处于ON状态。或者，第一信息指示转发器从第一时间点开始转发或者在第一时间点进入ON状态。转发器确定能够使用默认波束在第一时间转发。
采用默认波束或者由转发器自行确定波束进行转发的实施方法，有助于节省指示信息开销，提高有效数据传输效率。在FR1，由于其载波频率相较于FR2(Frequency range2)偏低，在一些情况下(例如转发器部署位置确定、覆盖面积偏小等)采用默认波束或者由转发器自行确定波束进行转发的实施方法也能够取得与采用自适应调整波束类似的性能。
在一些实施例中，第一时间包括灵活时间单位。第一信息用于指示所述第一时间中所包括的灵活时间单位为上行时间单位，和/或，所述第一信息用于指示所述第一时间中所包括的灵活时间单位为下行时间单位。第一信息指示所述第一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一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。第一信息指示所述第一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一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，第一信息指示NCR功率，该功率非零，NCR在第一时间使用该功率进行转发。
在一些实施例中，第一信息可以是显式指示转发，也可以是隐式指示转发。
在一些实施例中，例如，显式的第一信息可以用于指示NCR在第一时间点进入ON状态，如图18和19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)ON状态，如图6和8所示。再例如，显式的第一信息可以用于指示NCR在第一时间进行转发(例如使用默认波束)，如图6和8所示。
再例如，隐式的第一信息可以用于指示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在第一时间使用所述第一信息指示的波束进行转发。
又例如，隐式的第一信息可以用于向NCR指示第一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，所述第一信息为动态信令或者半静态信令。
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进行转发的信息。
--例如，第一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，第一信息动态地指示NCR与第一时间对应的转发波束，NCR在第一时间结束OFF状态，使用该指示的波束进行转发。
--又例如，第一信息动态地指示NCR功率，该功率非零，NCR在第一时间使用该功率进行转发。
--还例如，第一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，第一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，第一信息用于半静态地指示NCR处于ON的时间。
--又例如，第一信息用于半静态/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UE的半持续数据传输，基站通过第一信息半静态/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CSIRS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，第一信息用于半静态/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UE接入小区或者保持与基站连接等作用的公共信号。相较于上述用于UE的数据传输，这样的公共信号重要性比较高。因此，这样的第一信息指示的转发配置的优先级较高。除此以外，还可能有终端设备需要高优先级业务，其相应的转发优先级也较高。
在一些实施例中，上述半静态通过MAC CE或者RRC指示。在另一些实施例中，上述半持续通过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。
以下再对第二信息和/或第二时间进行进一步说明。
在所述第二时间中，所述转发器不被指示进行转发，或者，所述转发器不能够进行转发，或者，所述转发器不被期望进行转发。
在一些实施例中，在第二时间内由第二信息指示处于OFF状态的NCR不转发，具体可以包括：NCR在第二时间不会再被指示为ON(具体如何指示ON，可以参照前述第一信息处的描述)。
例如，NCR不期待在第二时间被指示为ON；
再例如，NCR不期待接收到新的指示，指示其在第二时间为ON(除非接收到 一个第二信息，改写前一个第二信息)。
再例如，NCR即使又收到了指示进行转发的其他信息，也仍然处于OFF状态。
在一些实施例中，所述第一时间对应的转发的优先级高，尽管所述第二时间被指示所述第二信息指示为OFF状态，转发器在所述第一时间进行转发。
例如，NCR在第二时间不转发，除非该第二时间包含的第一时间为高优先级时间(或者，特殊时间单位)。高优先级时间单位或者特殊时间单位用来转发重要信号的时间单位，例如，SSB信号、PRACH信号等。该第一时间单位可以由基站指示，和/或，为标准预定义，和/或，由NCR自行确定(例如接收系统信息)。
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，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，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。
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，第二信息可以是一次性指示的动态信息。例如，NCR收到该动态信息后进入OFF状态；又或者该动态信息指示一个时间段。该动态信息还可以是周期性的(具体周期相关信息可以由动态信令指示，也可以半静态的提前配置且由动态信令激活)。
再例如，第二信息也可以是半静态信息。例如，该半静态信息用于配置以省电为目的OFF状态，该半静态信息可以仅指示OFF状态对应的时间(例如第二时间)，也可以指示周期的ON状态时间(例如前述暂定的ON状态)和OFF状态时间。再例如，该半静态信息重用NCR-MT的DRX信令，NCR根据预定义规则解读DRX配置信令，并确定与OFF状态对应的第二时间。
以下再对转发器既接收到第一信息又接收到第二信息的情况进行说明。
图22是本申请实施例的第一信息和第二信息的一示例图。如图22所示，例如，在接收到第二信息之前接收到第一信息。其中，第一信息指示第一时间，第二信息指示第二时间。第一时间和第二时间不重叠。
图23是本申请实施例的第一信息和第二信息的另一示例图，示出了具有最小间隔的情况；图24是本申请实施例的第一信息和第二信息的另一示例图，示出了不具有最小间隔的情况。如图23和24所示，例如，在接收到第二信息之前接收到第一信息。其中，第一信息指示第三时间，第二信息指示第二时间。
以下以第三时间和第二时间至少部分重叠，且重叠部分为第一时间为例进行说明。
在一些实施例中，所述转发器在接收到所述第二信息之前接收到所述第一信息的情况下，根据所述第一信息在所述第一信息所指示的第三时间内进行转发，并根据所述第二信息在所述第二信息所指示的第二时间的剩余时间内不进行转发。
图25是本申请实施例的第一信息和第二信息的另一示例图，示出了具有最小间隔的情况；图26是本申请实施例的第一信息和第二信息的另一示例图，示出了不具有最小间隔的情况。如图25和26所示，第一信息指示的转发或者ON完成后，进入第二信息指示的OFF状态。
第二信息指示的OFF状态可以用于省电，这种处理有助于平衡数据转发与省电。可以完成指示的转发后，再进入OFF状态(停止转发)。此外，允许这样的冲突存在，可以减少网络设备在调度和指示之前进行规划的计算复杂度，进而降低网络设备的实现成本。
在一些实施例中，所述转发器在接收到所述第二信息之前接收到所述第一信息的情况下，根据所述第一信息在所述第一信息所指示的第三时间内的不与所述第二信息所指示的第二时间重叠的时间内进行转发，并根据所述第二信息在所述第二时间内不进行转发。
图27是本申请实施例的第一信息和第二信息的另一示例图，示出了具有最小间隔的情况；图28是本申请实施例的第一信息和第二信息的另一示例图，示出了不具有最小间隔的情况。如图27和28所示，NCR执行第一信息指示的ON/转发一段时间后，停掉(中止)第一信息指示的ON/转发，直接进入第二信息指示的OFF状态。
由此，有助于基站在指示的过程中，中断不必要的转发。例如，转发指示为提前预测的，在实际调度中，被指示的后半段转发时间已经没有信号需要转发了。基站可以通过及时地发送第二信息，让NCR尽快进入OFF状态。从而达到更好的省电目的。
在一些实施例中，所述转发器在接收到所述第二信息之前接收到所述第一信息的情况下，在所述第一信息所指示的第三时间内不进行转发，并根据所述第二信息在所述第二信息所指示的第二时间内不进行转发，所述第二时间与所述第三时间至少部分重叠。
图29是本申请实施例的第一信息和第二信息的另一示例图，示出了具有最小间隔的情况；图30是本申请实施例的第一信息和第二信息的另一示例图，示出了不具有最小间隔的情况。如图29和30所示，NCR不执行第一信息指示的ON/转发，直接进入第二信息指示的OFF状态。由此，能够达到最好的省电目的。
以上示意性对先收到第一信息再收到第二信息的情况进行了说明，但本申请不限于此。上述方式也可以结合实施。例如，如果收到第二信息的时候，已经开始了由第一信息指示的转发或者ON状态，可以采用图27所示的方式，尽可能早地停止该转发或者该ON状态。如果收到第二信息的时候，尚未开始由第一信息指示的转发或者ON状态，则可以采用图29的方式，直接根据第二信息指示，在第二时间进入OFF状态或者不做转发。
以下示意性对先收到第二信息再收到第一信息的情况进行说明。
图31是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第一间隔和第二间隔的情况；图32是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第二间隔的情况。如图31和32所示，例如，在接收到第二信息之后接收 到第一信息。其中，第一信息指示第三时间，第二信息指示第二时间。
以下以第三时间和第二时间至少部分重叠，且重叠部分为第一时间为例进行说明。
在一些实施例中，所述转发器在接收到所述第二信息之后接收到所述第一信息的情况下，根据所述第二信息在所述第二信息所指示的第二时间内不进行转发。
图33是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第一间隔和第二间隔的情况；图34是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第二间隔的情况。如图33和34所示，NCR不执行第一信息指示的ON/转发，保持第二信息指示的OFF状态。
由此，有助于NCR设备的节能(尽可能保持由第二信息指示的OFF状态)。此外，由于允许这种冲突存在，即允许网络设备发送这样不会被执行的第一信息，可以减少网络设备在调度和指示之前进行规划的计算复杂度，进而降低网络设备的实现成本。
在一些实施例中，所述转发器在接收到所述第二信息之后接收到所述第一信息的情况下，根据所述第一信息在所述第一信息所指示的第三时间内进行转发，并根据所述第二信息在所述第二信息所指示的第二时间不与所述第三时间重叠的时间内不进行转发，所述第二时间与所述第三时间至少部分重叠。
图35是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第一间隔和第二间隔的情况；图36是本申请实施例的第一信息和第二信息的另一示例图，示出了具有第二间隔的情况。如图35和36所示，NCR暂停第二信息指示的OFF状态，按照第一信息的指示在第一时间处于ON状态/进行转发。第一时间例如为高优先级时间(或者，特殊时间单位)。
由此，可以保证高优先级的信号被优先转发，提高系统的可靠性。
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，第一信息优先级高于第二信息，这种情况下优先执行第一信息。再例如，第二信息优先级高于第一信息，这种情况下优先执行第二信息。
再例如，在时间轴上先收到的信息所指示的状态和/或行为优先级较高，这种情况下优先执行先接收到的信息。
再例如，由NCR根据优先级是否高于阈值来确定，例如对于优先级低于预设阈 值的第一信息，其优先级低于第二信息；对于优先级高于预设阈值的第一信息，其优先级高于第二信息。
此外，以上说明中以第一时间为例，本申请不限于此。第一时间可以是两个信息中至少之一所指示的具体时间，也可以是指示时间的一部分。例如，当NCR接收到两个信息的时候，第一时间是两个信息指示的重叠部分。
在一些实施例中，可以将默认的OFF状态称为第一OFF状态，将指示的OFF状态称为第二OFF状态。
例如，转发器被期望(或确定或默认)为处于第一关闭(OFF)状态，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在第一时间处于第二关闭(OFF)状态的第二信息。
在一些实施例中，可以将第一信息指示的ON状态称为第一ON状态(也可称为指示的ON状态)，在该ON状态下转发器能够进行转发。将第二信息指示的ON状态称为第二ON状态(也可称为暂定的ON状态)，例如，在该ON状态下转发器还不能够进行转发，在接收到第一信息之后才能在与第一信息对应的第一时间上真正地进行转发。
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，转发器确定(或默认或被期望)在第一时间不进行转发，除非接收到来自网络设备的第一信息；以及所述转发器接收用于指示所述转发器在所述第一时间不进行转发的第二信息。由此，转发器默认在第一时间为OFF，从而能够减少不必要的干扰，提高整个网络的传输效率；此外在收到第二信息的情况下转发器被指示在第一时间为OFF，从而还能够降低系统功耗和节省能源开销。
