Definitions

  • the present application relates to the field of communication technology.
  • 5G (fifth generation mobile communication technology) systems can provide larger bandwidth and higher data rates, and can support more types of terminals and vertical services.
  • 5G systems are also deployed on new spectrum, which has significantly higher frequencies than the traditional telecommunication spectrum used by 3G and 4G systems.
  • 5G systems can be deployed in the millimeter wave band (28GHz, 38GHz, 60GHz and above, etc.).
  • 5G systems need cell coverage enhancement methods more than previous 3G and 4G systems, especially 5G systems deployed in the millimeter wave frequency band. How to better enhance the cell coverage of 5G systems has become an urgent problem to be solved.
  • RF repeaters are widely used in the actual deployment of 3G systems and 4G systems.
  • an RF repeater is a device that amplifies and forwards the signals between devices in the RF domain.
  • RF repeaters are a type of non-regenerative relay node that simply amplifies and forwards all received signals.
  • conventional RF repeaters are unable to exchange information with other devices (e.g. network devices/terminal devices, etc.). Specifically, in terms of reception, conventional RF repeaters do not support measurement/demodulation/decoding of forwarded signals, nor do they receive signals other than forwarded signals. In terms of transmission, conventional RF repeaters only amplify and forward signals, and do not support generating signals and sending signals generated by themselves. Therefore, the forwarding behavior of conventional RF repeaters is not controlled by the network (e.g., through network devices, etc.). For example, the switch state of the repeater is usually set manually.
  • the switch of a conventional repeater is usually manually set, and it cannot dynamically match the data transmission between the network device and the UE. Generally, data transmission is not performed between the network device and the terminal device all the time. If the repeater is turned on when there is no network device and the terminal device is not transmitting data, on the one hand, it will increase unnecessary power consumption, and on the other hand, it may also cause interference to other devices and reduce network throughput. Therefore, compared with the conventional repeater, it is necessary to add the function of turning on/off the repeater. However, there is currently no specific control method for the on/off state.
  • an embodiment of the present application provides an information indication method, a repeater and a network device.

  • a network device including:
  • a sending unit sends first control information to a forwarder, wherein the first control information at least includes first information for indicating time domain resources; and/or sends or does not send second control information, wherein the second control information is used to instruct the forwarding unit to forward a signal within the time domain resources.
  • a communication system comprising: the repeater of the aforementioned aspect and/or the network device of the aforementioned aspect.
  • the switch of the repeater can be controlled by the first control information so that the time domain resources corresponding to the on state of the repeater match the time domain resources of the data transmission between the network device and the terminal device, thereby saving the power consumption of the repeater and reducing the interference to other devices in the network, thereby improving the network throughput.

  • 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.

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(amplify)和转发(forward)设备往来信号的设备。也就是说，射频转发器是一种非再生类型的中继节点，它们只是将接收到的所有信号直接放大并转发。
发明人发现，传统射频转发器不能够和其他设备(e.g.网络设备/终端设备等)进行信息交互。具体地，在接收方面，传统射频转发器不支持对转发信号进行测量/ 解调/解码，也不接收转发信号之外的信号。在发送方面，传统射频转发器仅放大并转发信号，不支持生成信号和发送自身生成的信号。因此，传统射频转发器的转发行为不受网络(例如通过网络设备等)控制。例如，转发器的开关状态通常是人工进行设置的。
发明人认识到，传统转发器的开关通常是人工设置的，其不能动态匹配网络设备和UE之间的数据传输。一般地，网络设备和终端设备之间不会时时刻刻进行数据传输，如果转发器在没有网络设备和终端设备没有数据传输时也处于开启状态，一方面会增加不必要的功耗，另一方面也可能对其他设备造成干扰，降低网络吞吐量。因此，与传统转发器相比，需要新增转发器的开启/关闭的功能。但是，目前还没有开启/关闭状态的具体控制方法。
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。
根据本申请实施例的一方面，提供一种转发器，包括：
接收单元，其在所述转发器的移动终端接收第一控制信息，所述第一控制信息至少包括用于指示时域资源的第一信息；
所述转发器的转发单元在所述第一信息指示的时域资源为第一状态或第二状态或第三状态。
根据本申请实施例的另一方面，提供一种网络设备，包括：
发送单元，其向转发器发送第一控制信息，所述第一控制信息至少包括用于指示时域资源的第一信息；和/或发送或不发送第二控制信息，所述第二控制信息用于指示所述转发单元在所述时域资源内转发信号。
根据本申请实施例的另一方面，提供一种通信系统，包括：前述一方面的转发器和/或前述一方面的网络设备。
本申请实施例的有益效果之一在于：可以通过第一控制信息对转发器的开关进行控制，使得转发器开启状态对应的时域资源与网络设备和终端设备之间的数据传输的时域资源匹配，节省转发器功耗，同时减小对网络中其他设备的干扰，提升网络吞吐量。

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。

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。

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1是本申请实施例的NCR的一示意图。如图1所示，NCR 102被配置在网络设备101和终端设备103之间。NCR 102可以包括如下两个模块/部件：转发器的移动终端(NCR-MT)和转发器的转发单元(NCR-Fwd)；NCR-Fwd也可称为NCR的 路由单元(NCR-RU)。NCR-MT用于与网络设备通信(交互信息)，NCR-Fwd用于转发往来于网络设备和终端设备之间的信号，NCR-MT和NCR-Fwd为功能实体，其功能可以由相同或不同硬件模块实现。
如图1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(或者回程)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。具体地，NCR-MT通过C-link与网络设备通信；NCR-Fwd通过BH link和AC link转发信号。
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(或者BH)链路上进行发送或进行接收”可以等价于“在AC(或者BH)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。在某些情况下，“转发单元”可以与“转发行为”互换。
在本申请实施例中，转发器还可以表述为网络控制转发器(NCR)、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。
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。
第一方面的实施例

所述转发器的转发单元在所述第一信息指示的时域资源为第一状态或第二状态或第三状态。
值得注意的是，以上附图2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2的记载。
在一些实施例中，第一状态也可以称为开启(ON)状态或第一开启状态，第二状态也可以称为待机状态或切换状态或第二开启状态或第二关闭状态，第三状态也可以称为关闭(OFF)状态或关机状态或第一关闭状态。

在一些实施例中在第二状态和第三状态中，NCR(或者说NCR-Fwd)仅支持其中一个。例如，NCR支持第一状态和第二状态，或者第一状态和第三状态。
在一些实施例中，NCR(或者说NCR-Fwd)支持第二状态和第三状态。例如，NCR支持第一状态，第二状态和第三状态。
在一些实施例中，NCR(或者说NCR-MT)可以向网络设备上报其是否支持第二状态和/或第三状态。
在一些实施例中，仅针对第二状态或仅针对第三状态定义输出功率要求，例如，NCR在第二状态或第三状态的输出功率为不大于或小于下述第二功率(或者说功率水平)。

在一些实施例中，针对第二状态和第三状态的输出功率要求相同，例如，NCR在第二状态和第三状态的输出功率为不大于或小于下述第二功率(或者说功率水平)。
在一些实施例中，针对NCR-Fwd在第二状态和第三状态的输出功率要求不同。例如，若NCR-Fwd处于第二状态，NCR-Fwd的输出功率不大于或小于第二功率，若NCR-Fwd为第三状态，NCR-Fwd的输出功率不大于或小于第三功率。第二功率和第三功率的值不同，例如，第二功率大于第三功率。
在一些实施例中，第二功率/第三功率是指功率谱密度(dBm/MHz)，可以分别称为第二功率谱密度和第三功率谱密度。例如，第二功率等于-85dBm/MHz，第三功率 小于-85dBm/MHz,或者，第二功率大于-85dBm/MHz，第三功率等于-85dBm/MHz。再例如，第二功率等于-50dBm/(SCS×(12×N RB+1)/1000)MHz，第三功率小于-50dBm/(SCS×(12×N RB+1)/1000)MHz；或者，第二功率大于-50dBm/(SCS×(12×N RB+1)/1000)MHz，第三功率等于-50dBm/(SCS×(12×N RB+1)/1000)MHz，该子载波间隔SCS例如是转发信号(并非在转发的)的SCS，但不限于此。再例如，第二功率等于-36dBm/MHz，第三功率小于-36dBm/MHz,或者，第二功率大于-36dBm/MHz，第三功率等于-36dBm/MHz。
在一些实施例中，可以针对上行和下行分别定义针对NCR-Fwd的输出功率要求，也就是说，针对BH link和AC link的输出功率分别定义上述第二功率和/或第三功率。例如，针对下行或者说AC link的输出功率，第二功率等于-85dBm/MHz，第三功率小于-85dBm/MHz,或者，第二功率大于-85dBm/MHz，第三功率等于-85dBm/MHz，针对上行或者说BH link的输出功率，第二功率等于-50dBm/(SCS×(12×N RB+1)/1000)MHz，第三功率小于-50dBm/(SCS×(12×N RB+1)/1000)MHz；或者，第二功率大于-50dBm/(SCS×(12×N RB+1)/1000)MHz，第三功率等于-50dBm/(SCS×(12×N RB+1)/1000)MHz，该子载波间隔SCS例如是转发信号(并非在转发的)的SCS，但不限于此。

在一些实施例中，NCR-Fwd在第二状态或第三状态的输出功率定义分别为：在其处于第二状态或第三状态的时间段内，超过/大于/不少于某一时间长度内测量得到 的平均功率。例如，在其处于第二状态或第三状态的时间段内，由带宽等于NCR-Fwd的通带带宽(passband bandwidth)且以指定的信道频率为中心(centred on the assigned channel frequency)的滤波器(e.g.方形滤波器)滤波，超过/大于/不少于某一时间长度内测量得到的平均功率。其中，该时间长度例如与SCS相关，例如，该时间长度＝70/Nus，N＝SCS/15。该SCS例如是转发信号(并非在转发的)的SCS，但不限于此。
在一些实施例中，支持转发单元从第三状态直接过渡(或者说切换)到第一状态。或者，不支持转发单元从第三状态直接过渡到第一状态和/或从第一状态直接过渡到第三状态，也就是说，若NCR-Fwd是第三状态，其必须先过渡到第二状态，才能再由第二状态过渡到第一状态。类似地，支持或不支持转发单元从第一状态直接过渡到第三状态。
在一些实施例中，仅定义第一状态和第二状态之间的过渡时间(或者说切换时间)或仅定义第一状态和第三状态之间的过渡时间，例如，为下述第一过渡时间。也就是说仅第一状态和第二状态切换时包括该第一过渡时间，第一状态和第三状态切换时不包括该第一过渡时间，或者说，仅第一状态和第三状态切换时包括该第一过渡时间，第一状态和第二状态切换时不包括该第一过渡时间。

或者，转发单元在时间段D为第二状态或第三状态，所述移动终端在所述时间段监听用于指示所述转发单元转发信号的DCI格式，或者，所述移动终端在所述时间段接收指示所述转发单元在所述时间段内转发信号的第二控制信息，或者，所述移动终端在接收所述第一控制信息之后接收指示所述转发单元在所述时间段内转发信号的第二控制信息。
在一些实施例中，第一状态、第二状态和第三状态是指转发器的移动终端 (NCR-MT)的状态，上述第一状态、第二状态或第三状态用于表征NCR-MT的工作状态或者说开关状态。
在一些实施例中，第三状态表征NCR-MT不会在C-link发送或接收信号，例如在第三状态下，所述移动终端(NCR-MT)在时间段D不接收部分或全部下行信号，和/或，不发送部分或全部上行信号。例如，该下行信号包括用于指示转发单元转发信号的第二控制信息，该第二控制信息包括RRC或MAC CE或DCI。
在一些实施例中，第三状态表征NCR-MT不监听在C-link发送或接收信号或不期望在C-link发送或接收信号，例如，在第三状态下，所述移动终端在该时间段D不监听用于指示所述转发单元转发信号的DCI格式，或者所述移动终端不期望在该时间段接收到指示所述转发单元转发信号的第二控制信息(例如DCI)，或者所述移动终端不期望接收到指示所述转发单元在所述时间段内转发信号的第二控制信息(例如RRC或MAC CE或DCI)。
或者，第二状态或第三状态表征NCR-MT监听在C-link发送或接收的信号或在C-link发送或接收信号，例如，在第二状态或第三状态下，所述移动终端在所述时间段监听用于指示所述转发单元转发信号的DCI格式，或者，所述移动终端在所述时间段接收指示所述转发单元在所述时间段内转发信号的第二控制信息，或者，所述移动终端在接收所述第一控制信息之后接收指示所述转发单元在所述时间段内转发信号的第二控制信息。
在一些实施例中，以上第一状态、第二状态或第三状态对应的时间段由网络设备配置的时域资源表示，即所述转发器的移动终端接收网络设备发送的第一控制信息，该第一控制信息可以包括DCI和/或RRC信令和/或MAC CE，所述第一控制信息至少包括用于指示时域资源(时间段)的第一信息；该第一信息可以显式或隐式指示所述转发单元在所述时域资源为第一状态或第二状态或第三状态，由此，所述转发器的转发单元在所述第一信息指示的时域资源为第一状态或第二状态或第三状态。
以下说明如何通过第一信息指示时域资源。
在一些实施例中，该第一信息可以由一个或多个第一信息域承载，该一个或多个第一信息域指示该时域资源的起始位置(偏移)和/或时长和/或间隔和/或周期。该时域资源是周期性的或半持续的或非周期性的。前述起始位置(偏移)和/或时长和/或间隔和/或周期可以以以下时间单位为粒度指示。该时间单位例如是子帧、时隙、符 号、小时隙(mini-slot)、毫秒等等。
在一些实施例中，第一信息域可以包括该时域资源的起始位置(偏移)和/或时长和/或间隔和/或周期包括的时间单位的数量(例如后述示例中Element_2中field_1和/或field_2)，通过该时间单位的数量来指示该时域资源的起始位置(偏移)和/或时长和/或间隔和/或周期，或者该第一信息域包括时间单位的索引(例如后述示例中Element_2中field_3)，或者该第一信息域(例如后述时域资源分配信息域)也可以包括一个行索引值，通过该索引值结合时域资源分配表指示起始位置(偏移)和/或时长和/或间隔和/或周期。
在一些实施例中，在由多(X)个第一信息域承载时，不同第一信息域指示的与时域资源相关的信息不同，例如不同第一信息域可以分别指示偏移，时长，周期等不同的信息(例如后述示例中Element_2中field_1和field_2和field_3)，或者不同第一信息域指示时间单位不同，例如不同第一信息域分别指示时隙和符号等；或者不同第一信息域指示的时域资源不重叠或不完全重叠，本申请实施例并不以此作为限制。
在一些实施例中，在由多(X)个第一信息域承载时，X个第一信息域可以分为多(Y)组第一信息域，每组第一信息域包括一个或多(Z)个第一信息域，一组第一信息域指示时域资源的一部分资源，不同组信息域指示的时域资源不重叠或不完全重叠。例如后述示例6中，Element_2包括一组第一信息域，其中包括3个第一信息域field_1和field_2和field_3。
在一些实施例中，该第一控制信息还可以包括或不包括用于指示一个或多个接入链路波束的第二信息。其中，所述第一控制信息是否包括第二信息与所述转发单元的工作频带(或者频率范围)和/或能力和/或高层参数配置有关。
例如，与工作频带(或者频率范围)相关：转发单元的工作频带在FR1时，第一控制信息不包括第二信息，转发单元的工作频带在FR2时，第一控制信息包括第二信息；
例如，与能力相关：在转发器的接入链路波束固定(或者说只支持一个接入链路波束(模拟波束))时，第一控制信息包括第二信息。在转发器的接入链路波束可以调整或转换(或者说转发器支持多于一个接入链路波束)时，第一控制信息包括第二信息；在该示例中，转发器可以向网络设备发送或不发送能力相关信息。该能力相关信息例如包括该转发器支持的接入链路波束的数量，和/或波束索引，和/或空间特性 相关信息。关于波束索引将在后述进行说明。
例如，转发器的工作频带在FR1，默认接入链路波束固定(或者说只支持一个接入链路波束(模拟波束))，该转发器无需向网络设备发送该能力相关信息；或者，如果该转发器的接入链路波束可以调整/转换(或者说转发器支持多于一个接入链路波束)，则向网络设备发送该能力相关信息，否则，无需向网络设备发送该能力相关信息。
例如，该转发器的工作频带在FR2，默认接入链路波束可以调整/转换(或者说转发器支持多于一个接入链路波束)，该转发器无需向网络设备发送该能力相关信息，或者，如果该转发器的接入链路波束固定(或者说只支持一个接入链路波束(模拟波束))，则向网络设备发送该能力相关信息，否则，无需向基站发送该能力相关信息。
再例如，该转发器的工作频带在FR1或FR2，无论接入链路波束是固定的还是可以调整/转换(或者说转发器支持多于一个接入链路波束)，该转发器均向网络设备发送该能力相关信息，例如，当接入链路波束固定时，上报的接入链路波束数量为1，或者接入链路波束可以调整/转换(或者说转发器支持多于一个(N个)接入链路波束)，上报的接入链路波束数量为N。
例如，与高层参数配置(时间上在第一控制信息之前)相关：例如，假设第一控制信息是DCI(DCI format X_Y),该高层参数是RRC信令的一个信息域，该信息域(直接或间接地)用于配置DCI format X_Y是否包括第二信息。例如，该高层参数可以是1比特，在高层参数配置包括第二信息(例如比特值为1)时，DCI format X_Y包括第二信息，在高层参数配置不包括第二信息(例如比特值为0)时，DCI format X_Y不包括第二信息。再例如，在某一信息元IE或另一信息域包括该信息域的情况下，DCI format X_Y包括第二信息，否则，不包括第二信息。再例如，该高层参数用于配置DCI format X_Y所能指示的接入链路波束所能指示的波束(例如称为候选波束)，配置了转发器的其中一个接入链路波束为候选波束，则DCI format X_Y不包括第二信息。配置了多于一个接入链路波束为候选波束，DCI format X_Y包括第二信息。
例如，高层参数exampleField_4以及exampleField_5使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022130145-appb-000001
其中，exampleField_4用于配置DCI format X_Y中用于指示接入链路波束的信息域，INTEGER(0..3)可以是该信息域的比特数，可选的，也可以包括Element_3，该Element_3用于配置该信息域对应的波束图样的列表(假设该信息域指示一个波束图样的索引)。关于该exampleField_4可以存在或不存在，即exampleField_4是有条件存在的，该条件XYZ1包括针对FR2(或者FR2-1)，可选存在(optional present)；针对FR1，不存在(absent)；或者针对FR2(或者FR2-1)，必须存在(mandatory present)；针对FR1，不存在(absent)；或者针对FR2(或者FR2-1)，必须存在(mandatory present)；针对FR1，可选存在(optional present)。
其中，exampleField_5用于配置DCI format X_Y中用于指示时域资源的信息域，Element_4配置该信息域对应的时域资源列表，例如PDSCH-TimeDomainResourceAllocationList。
例如，高层参数ExampleIE_6或exampleField_6使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2022130145-appb-000002
其中，ExampleIE_6或exampleField_6用于配置DCI format X_Y，aField用于配置DCI format X_Y中用于指示接入链路波束的信息域，INTEGER(0..3)可以是该信息域的比特数，可选的，也可以包括Element_3，该Element_3用于配置该信息域对应的波束图样的列表(假设该信息域指示一个波束图样的索引)，本申请实施例并不以此作为限制，关于该aField可以存在或不存在，即aField是有条件存在的，该条件XYZ1如前所述，此处不再赘述。anotherField用于配置DCI format X_Y中用于指示时域资源的信息域，Element_4配置该信息域对应的时域资源列表，例如PDSCH-TimeDomainResourceAllocationList。
例如，第二信息可以是一个或多个接入链路波束的相关信息，该相关信息包括波束类型和/或波束索引等，关于波束类型和索引将在后述进行说明。
在一些实施例中，所述第一控制信息还包括或不包括用于指示所述第一状态或第二状态或第三状态的第三信息。例如，该第三信息可以是1比特信息或2比特信息，使用1比特或2比特信息指示转发单元的状态是第一状态还是第二状态还是第三状态，例如比特值为0时，指示第一状态，比特值为1时，指示第三状态，此处不再一一示 例。
在一些实施例中，第一控制信息是DCI(DCI format X_Y)，对应第二信息和第三信息的包括同一信息域，也就是说，DCI format X_Y中的同一信息域在不同情况下提供第二信息或第三信息。例如，针对FR1，该信息域用于提供第三信息，针对FR2，该信息域用于提供第二信息。再例如，在NCR支持或者被配置了仅一个接入链路波束的情况下，该信息域用于提供第三信息，在NCR支持或者被配置了多于一个接入链路波束的情况下，该信息域用于提供第二信息。
以下示例说明第一控制信息的实施方式。
在一些实施例中，第一信息显式指示所述转发单元在所述时域资源为第一状态或第二状态或第三状态，也就是说所述第一信息仅用于指示所述转发单元在所述时域资源为第一状态或第二状态或第三状态，不会指示其他内容。
在该实施例中，第一控制信息包括或不包括用于指示一个或多个接入链路波束的第二信息。例如，转发器的工作频带在FR1时，和/或不支持波束控制或指示，和/或接入链路波束可以是默认的或者固定的或者缺省的(只支持一个模拟波束)，因此，网络设备不会向终端设备发送用于指示一个或多个接入链路波束的第二信息，或者说，不会在第一控制信息中发送用于指示一个或多个接入链路波束的第二信息。
以上实施例中，以第二信息指示一个或多个接入链路波束为例，但本申请实施例并不以此作为限制，该第二信息还可以指示一个或多个回程链路波束，其实施方式类似，本申请实施例不再一一重复。
在该实施例中，第一控制信息还可以包括用于指示第一状态或第二状态或第三状态的第三信息。
例如，第一控制信息包括第一信息，不包括第二信息，可选的，还可以包括第三信息，在该情况下接入链路波束可以是默认的或者固定的或者缺省的，该第一信息仅指示所述转发单元在所述时域资源为第一状态或第二状态或第三状态。
在一些实施例中，第一信息隐式指示所述转发单元在所述时域资源为第一状态或第二状态或第三状态，第一信息还用于指示一个或多个接入链路波束和/或一个或多个回程链路波束对应的时域资源。该一个或多个接入链路波束和/或一个或多个回程链路波束由第二控制信息中包括的第二信息指示。例如，转发器的工作频带在FR2，和/或支持波束调整或指示或转换(或者说转发器支持多于一个(N个)接入链路波 束)，因此，网络设备向终端设备发送用于指示一个或多个接入链路波束的第二信息。
例如，第一控制信息包括第一信息和第二信息，该第二信息指示一个或多个接入链路波束和/或一个或多个回程链路波束，第一信息指示一个或多个接入链路波束和/或一个或多个回程链路波束对应的时域资源，同时，该第一信息还可以隐式指示所述转发单元在所述时域资源的状态为第一状态或第二状态或第三状态。
以下示例说明。
以下先说明如何定义接入(AC)链路波束的索引。
AC链路波束也可以称为终端设备侧波束，是指转发器在AC链路采用的(使用)的接收波束/发送波束，该发送波束将来自网络设备的信号转发至终端设备，该接收波束将来自终端设备的信号转发给网络设备。回程链路波束也可以称为网络设备侧波束，是指转发器在BH链路采用的(使用)的接收波束/发送波束，该接收波束将来自终端设备的信号转发至网络设备，该发送波束将来自网络设备的信号转发给终端设备。其中，波束(天线的)例如是指天线阵列(antenna array)的辐射图样(radiation pattern)的主波瓣(main lobe)。
在一些实施例中，转发器可以支持多个不同方向和/或宽度的波束(或者说天线波束)，波束之间可能存在关联关系。例如，第一波束和第二波束之间存在关联关系包括：第一波束和第二波束的波束中心方向相同，和/或第一波束和第二波束的波束峰值方向相同，和/或第一波束和第二波束是准共址(例如QCL类型D)，和/或第一波束在第二波束范围内，或第二波束在第一波束范围内，和/或第一波束的波束宽度在第二波束的波束宽度范围内，和/或第二波束的波束宽度在第一波束的波束宽度范围内。其中，波束中心方向例如是指该波束的半功率轮廓(half power contour)的几何中心，波束峰值方向例如是指该波束的最大EIRP(maximum EIRP)所在的方向。
例如1，NCR支持的波束依次编号，该编号可以按空间关系进行。例如，相邻编号的波束在空间上是相邻的。例如，NCR支持4个波束，从0或1开始编号，各自的索引分别是0～3或1～4。
例如2，NCR同时支持第一波束(宽波束)和第二波束(窄波束)，波束依次编号，该编号可以按空间关系进行。例如，先编号宽波束，再编号窄波束，相邻编号的宽波束在空间上是相邻的，相邻编号的窄波束在空间上是相邻的。或者，先编号一个宽波束和与该宽波束关联的窄波束，再以相同方式编号其他宽波束和窄波束，例如， 图4A是本申请实施例中波束索引示意图，如图4A所示，NCR支持2个宽波束(第一波束)，8个窄波束(第二波束)，前4个窄波束关联第一个宽波束，后4个窄波束关联第二个宽波束。所有波束从0或1开始编号，例如0～9(或未图示的1～10)。编号时可以前两个为宽波束，剩余为窄波束，或者第1和第6个编号为宽波束，其他为窄波束。
例如3，NCR同时支持第一波束(宽波束)和第二波束(窄波束)，第一波束和第二波束分别依次编号，该编号可以按空间关系进行，相邻编号的宽波束在空间上是相邻的，相邻编号的窄波束在空间上是相邻的。例如，图4B是本申请实施例中波束索引示意图，如图4B所示，NCR支持2个宽波束(第一波束)，8个窄波束(第二波束)。宽波束和窄波束分别从0或1开始编号，例如宽波束0～1(或未图示的1～2)，窄波束0～7(或未图示的1～8)。例如。前4个窄波束关联第一个宽波束，后4个窄波束关联第二个宽波束。
例如4，NCR同时支持第一波束(宽波束)和第二波束(窄波束)，第一波束和第二波束是按层级编号的，分别从0或1开始编号，该编号可以按空间关系进行。相邻编号的宽波束在空间上是相邻的，相邻编号的窄波束在空间上是相邻的。针对相邻编号的宽波束，编号较小的宽波束关联的窄波束中编号较大的与编号较大的宽波束关联的窄波束中编号较小的在空间上相邻。例如，图4C是本申请实施例中波束索引示意图，如图4C所示，NCR支持2个宽波束(第一波束)，8个窄波束(第二波束)。宽波束编号为0～1(或未图示的1～2)，关联第一个宽波束的4个窄波束和关联第二个宽波束的4个窄波束分别编号为0～3或(或未图示的1～4)。
上述索引均以一维为例，但本申请实施例并不以此作为限制，该索引也可以是二维或三维的。例如，波束可以按照二维阵列排列，可以对水平方向波束和垂直方向波束水平分别编号，该索引即为二维的索引，此处不再一一举例。
在一些实施例中，可编号波束对应的波束的范围可以是NCR可用于转发的所有波束或者该第一控制信息所能指示的所有波束(网络设备高层参数配置的候选波束)和/或NCR支持的所有波束，或者说，一个波束可以对应一个或多个波束索引(多个波束索引分别是预定义的和/或NCR上报给网络设备的和/或网络设备配置的)。例如，一个波束对应第一索引和第二索引，其中，第一索引是在NCR支持的所有波束中唯一标识该波束的索引，第二索引是在NCR可用于转发的所有波束或者该第一控制信 息所能指示的所有波束(网络设备高层参数配置的候选波束)中唯一标识该波束的索引。
在上述示例中，第一控制信息包括第一信息和第二信息，该第二信息指示的一个或多个接入链路波束与第一信息指示的时域资源对应，在第二信息指示多个接入链路波束时，多个接入链路波束是时分或频分。
在一些实施例中，该第一信息由一个第一信息域承载，第一信息域指示的时域资源对应一个接入链路波束；该第二信息由一个或多个第二信息域承载，该一个或多个第二信息域指示一个接入链路波束，对应该一个第一信息域指示的时域资源；
例如(一)，在由多(M)个第二信息域承载时，不同第二信息域指示的与波束相关的信息不同。例如包括2个第二信息域时，一个用于指示波束类型(宽波束/窄波束)，另一个用于指示(该波束类型的波束的)波束索引，或者，一个用于指示波束组标识，另一个用于指示(该波束组的波束的)波束索引，或者，一个用于指示宽波束的索引，另一个用于指示窄波束的索引(例如基于上述关于索引的例3，可以分别预留特定值表示没有指示宽波束或窄波束；例如基于上述关于索引的例4，仅用于指示窄波束的索引的第二信息域预留特定值表示没有指示窄波束(或者说，表示该DCI指示的是宽波束))。
例如(二)，包括1个第二信息域时，该第二信息域直接或间接指示接入链路波束的波束索引(第一索引或第二索引)。直接指示时，该第二信息域的十进制值等于波束的索引值，从而指示相应波束。间接指示时，第二信息域的十进制值/二进制值按从小到大的顺序映射到从小到大的波束的索引值，从而指示相应波束。或者，第二信息域中的比特按MSB到LSB(或者相反)的顺序映射到从小到大的波束的索引值，若一个比特值为0，则没有指示相应波束，若一个比特值为1，则指示了相应波束(仅有一个比特位为1，其他为0)。例如针对例1，第二信息域可以为0001，指示最后一个编号的波束。
在一些实施例中，该第一信息由一个第一信息域承载，第一信息域指示的时域资源对应一个或多个接入链路波束，该第二信息由一个或多个第二信息域承载，该一个或多个第二信息域指示一个或多个接入链路波束，对应该一个第一信息域指示的时域资源。
例如(三)，第二信息由多(K)个第二信息域承载时，每个第二信息域指示一 个接入链路波束，多个第二信息域指示的接入链路波束根据预定义规则对应第一信息域指示的时域资源的不同部分(时分)，或者多个第二信息域指示的接入链路波束均对应第一信息域指示的时域资源的全部(频分)，或者时域资源的混合。
例如(四)，第二信息由多(K)个第二信息域承载时，K个第二信息域可以分为多(N)组第二信息域，每组第二信息域包括一个或多(M)个第二信息域，每组第二信息域指示一个接入链路波束，多组第二信息域指示的接入链路波束根据预定义规则对应第一信息域指示的时域资源的不同部分(时分)，或者多组第二信息域指示的接入链路波束均对应第一信息域指示的时域资源的全部(频分)，或者时域资源的混合。在一组第二信息域中包括M个第二信息域时，不同第二信息域指示的与波束相关的信息不同。具体指示方式如(一)所述，此处不再赘述。
在一些实施例中，该第一信息由多个第一信息域承载，多个第一信息域指示的时域资源对应一个或多个接入链路波束。例如，不同第一信息域指示的与时域资源相关的信息不同。例如，第一信息由2个第一信息域承载，不同第一信息域还是的时间单位不同，一个用于指示时隙，另一个用于指示符号；或者不同第一信息域指示的信息不同，一个用于指示起始位置，另一个用于指示时长(duration)。再例如，第一信息由3个第一信息域承载，分别用于指示时隙偏移，符号偏移以及时长(duration)。或者，例如，不同第一信息域指示的时域资源不重叠或不完全重叠。该多个第一信息域指示的时域资源是该多个第一信息域指示的时域资源的并集。
例如(五)，该第一信息由多个第一信息域承载，该第二信息由一个或多个第二信息域承载，该一个或多个第二信息域指示一个接入链路波束，对应该多个第一信息域指示的时域资源。在第二信息由一个第二信息域承载时，该一个第二信息域直接或间接指示该一个接入链路波束，具体指示方式见(二)，此处不再赘述，在第二信息由多个第二信息域承载时，不同第二信息域指示的与波束相关的信息不同。具体指示方式见(一)，此处不再赘述，
例如(六)，该第一信息由多个第一信息域承载，该第二信息由一个或多个第二信息域承载，该一个或多个第二信息域指示一个或多个接入链路波束，对应该多个第一信息域指示的时域资源。例1：第二信息由多(K)个第二信息域承载时，每个第二信息域指示一个接入链路波束，各个第一信息域和各个第二信息域一一对应，即一个第二信息域指示的接入链路波束应用于其对应的第一信息域指示的时域资源。例2： 第二信息由多(K)个第二信息域承载时，K个第二信息域可以分为多(N)组第二信息域，每组第二信息域包括一个或多(M)个第二信息域，每组第二信息域指示一个接入链路波束，各个第一信息域和各组第二信息域一一对应；一组第二信息域指示的接入链路波束应用于其对应的第一信息域指示的时域资源。在一组第二信息域中包括M个第二信息域时，不同第二信息域指示的与波束相关的信息不同。具体指示方式如(一)所述，此处不再赘述。
在一些实施例中，该第一控制信息可以是RRC信令。
在一些实施例中，该第一控制信息是RRC信令时，该RRC信令中的同一信息元(示例中的ExampleIE_1)或同一域(示例中的exampleField_1)在不同的情况分别用于配置接入链路波束，或者用于配置转发单元为第一状态或第二状态或第三状态。

在一些实施例中，NCR(例如NCR-MT)可以配置在专用搜索空间USS和/或公共搜索空间CSS监听DCI format X_Y。例如，如果DCI format X_Y是单播或专用(unicast/dedicated)的，可以配置在USS监听该DCI format，相应用于加扰CRC的RNTI例如是第一C-RNTI，或NCR-RNTI或第二C-RNTI，第二MCS-C-RNTI。如果DCI format X_Y是共群(group common)的，可以配置在CSS监听该DCI format，该CSS例如是Type3-PDCCH CSS set，相应用于加扰CRC的RNTI例如是SFI-RNTI，或NCR-RNTI或第二C-RNTI，第二MCS-C-RNTI。
例如，该DCI包括一个或多个第一信息域，所述第一信息域包括时域资源分配信息域。一个TDRA信息域通过行索引指示一行TDRA配置。时域资源分配(TDRA)表(或者简称为TDRA表)包括至少一行，以下，为方便描述，将一行称为一个TDRA配置，即TDRA表包括至少一个TDRA配置。一个TDRA配置包括至少一个时域资源配置，时域资源配置中至少包括时隙中的符号位置(起始位置符号+长度)配置；另外，可选的。一个TDRA配置还可以包括至少一个时隙偏移K0配置；该一个TDRA配置还可以包括或不包括其他信息(例如，映射类型，mapping type)本申请实施例并不以此作为限制。其中，关于时隙中的符号位置配置，其例如包括start and length indicator SLIV,该SLIV对应起始符号(S)和长度(L)的有效组合(valid combination)，或者，其例如对应起始符号starting symbol配置和长度length配置，该starting symbol 配置和length配置是有效组合。
在一些实施例中，该第一控制信息相关的第一时间位置可以是承载该第一控制信息的时域资源或者物理信道(PDCCH/PDSCH)所在的时隙或最后一个时隙或最后一个符号，或者，该第一时间位置也可以是所述第一控制信息或者承载该第一控制信息的物理信道(PDCCH/PDSCH)对应的HARQ-ACK信息所在的子帧或时隙或最后一个时隙或最后一个符号，例如，在该第一控制信息是DCI时，该DCI由PDCCH承载，该第一时间位置可以是承载DCI的PDCCH所在的子帧或时隙或最后一个时隙或最后一个符号，或者该第一时间位置可以是该DCI或承载该DCI的PDCCH对应的HARQ-ACK反馈(所在的PUCCH/PUSCH)所在的子帧或时隙或最后一个时隙或最后一个符号。例如该第一控制信息是MAC CE，该MAC CE可以由PDSCH承载，该第一时间位置是承载该MAC CE的PDSCH对应的HARQ-ACK反馈(所在的PUCCH/PUSCH)所在的子帧或时隙或最后一个时隙或最后一个符号。
在一些实施例中，该所述第一信息指示的时域资源的第二时间位置是第一信息指示的时域资源所在的子帧或时隙或所在的第一个时隙或所在的第一个符号。
在一些实施例中，如果接收第一控制信息时转发器的状态或者说第一信息指示时域资源前转发器的状态和第一信息指示的时域资源的状态不相同，那么状态的切换也需要一定的过渡时间，此外，还可能包括一些其他转发器处理行为的时间(例如波束切换)和/或接收该第一控制信息所需要的时间(解码)等，因此，该第一时间位置和所述第一信息指示的时域资源的第二时间位置之间的第一间隔大于或不小于第一预定值或第二预定值。所述第一预定值大于所述第二预定值。以下先以从第三状态或第二状态转换到第一状态为例进行说明。

以上以第三状态或第二状态转换到第一状态为例进行说明，在转发器由第一状态转换到第三状态，以及第一状态转换到第二状态的实施方式类似；而在转发器由第二状态切换到第三状态，或者由第三状态切换到第二状态时，例如所述转发单元在接收所述第一控制信息时为第三状态或者所述转发单元在所述第一信息指示的时域资源 前为第三状态，在所述指示的时域资源为第二状态，所述第一间隔大于或不小于第五预定值。例如，该第五预定值包括从第三状态切换到第二状态所需要的时间，可选的，所述第五预定值还可以包括或不包括所述移动终端接收所述第一控制信息所需要的时间。
以上以状态切换为例说明该第一间隔的实施方式，以下以第一控制信息是否包括第二信息为例说明该第一间隔(以下称为第二间隔)的实施方式。
在一些实施例中，所述第一控制信息相关的第三时间位置和所述第一信息指示的时域资源的第四时间位置之间的第二间隔大于或不小于第三预定值或第四预定值。所述第三预定值大于所述第四预定值。该第三时间位置可以参考第一时间位置，该第四时间位置可以参考第二时间位置，此处不再重复。
在一些实施例中，所述第一控制信息包括用于指示一个或多个接入链路波束的第二信息，所述第二间隔大于或不小于所述第三预定值。
例如，该第三预定值包括所述转发单元从第三状态切换到第一状态所需要的时间，其中所述从第三状态切换到第一状态所需要的时间包括波束切换所需要的时间，可选的，所述第三预定值还可以包括或不包括所述移动终端接收所述第一控制信息所需要的时间。

或者，例如，所述第四预定值包括波束切换所需要的时间。可选的，所述第四预定值还可以包括或不包括所述移动终端接收所述第一控制信息所需要的时间。
在以上各个示例中，各预定值是否包括移动终端接收第一控制信息所需要的时间可以根据是否反馈针对该第一控制信息的HARQ-ACK确定。
例如在反馈时，该第一(三)时间位置是基于HARQ-ACK的位置(例如DCI或MAC CE对应的HARQ-ACK信息所在的时隙或最后一个时隙或最后一个符号)，则各预定值无需包括移动终端接收第一控制信息所需要的时间；在第一(三)时间位置是基于第一控制信息的(承载DCI的PDCCH所在的时隙或最后一个时隙或最后一个符号)，则各预定值需包括移动终端接收第一控制信息所需要的时间。
例如在不反馈：第一(三)时间位置是基于第一控制信息的(承载DCI的PDCCH所在的时隙或最后一个时隙或最后一个符号)，则各预定值需包括移动终端接收第一控制信息所需要的时间。
以下说明如何确定是否反馈HARQ-ACK信息。
在一些实施例中，所述转发器的移动终端发送或不发送所述第一控制信息对应的HARQ-ACK信息。
在一些实施例中，所述移动终端是否发送所述第一控制信息对应的HARQ-ACK信息与所述转发器的能力和/或高层参数配置相关。或者说是否支持针对所述第一控制信息的HARQ-ACK反馈与所述转发器的能力和/或高层参数配置相关。例如，该第一控制信息可以是DCI。
例如，与能力相关：假设第一控制信息是DCI(DCI format X_Y)，NCR向基站上报支持或不支持对DCI format X_Y的HARQ-ACK反馈，若上报了支持，则NCR接收到DCI format X_Y后向基站发送对应的HARQ-ACK信息(ACK)，否则，NCR接收到DCI format X_Y后不向基站发送对应的HARQ-ACK信息(ACK)。在一些情况下，默认NCR不支持，因此，NCR仅在支持的情况下向基站上报支持对DCI format X_Y的HARQ-ACK反馈，否则不用上报。。
例如，与高层参数配置相关：假设第一控制信息是DCI(DCI format X_Y)，该高层参数是RRC信令的一个信息域，该信息域(直接或间接地)用于配置NCR是否对DCI format X_Y进行HARQ-ACK反馈，若配置为对DCI format X_Y进行HARQ-ACK反馈，则NCR接收到DCI format X_Y后向基站发送对应的HARQ-ACK信息(ACK)，否则，NCR接收到DCI format X_Y后不向基站发送对应的HARQ-ACK信息(ACK)。例如，该高层参数可以是1比特的信息元，在高层参数(例如由RRC承载)配置比特值为1时，针对所述第一控制信息的HARQ-ACK反馈，在高层参数(例如由RRC承载)配置比特值为0时，不针对所述第一控制信息的HARQ-ACK反馈。一般地，若如上所述，NCR的能力不支持该HARQ-ACK反馈，该高层参数不应配置为对DCI format X_Y进行HARQ-ACK反馈。
在一些实施例中，所述转发器的移动终端发送所述第一控制信息对应的HARQ-ACK信息，所述第一信息指示的时域资源的起始位置在用于发送所述HARQ-ACK信息的时域资源的结束位置之后(保证可靠性)或者之前(降低时延)或者相同。其中，发送HARQ-ACK信息的时域位置可以是预定义或者由网络设备指示的，网络设备可以考虑时延和可靠性因素配置该第一信息指示的时域资源的起始位置。
在一些实施例中，所述转发器的移动终端发送所述第一控制信息对应的 HARQ-ACK信息，所述第一信息指示的时域资源的位置与用于发送所述HARQ-ACK信息的时域资源的位置不相关。或者说，所述第一信息指示的时域资源的位置不受限于用于发送所述HARQ-ACK信息的时域资源的位置，或者说，网络设备在配置该第一信息指示的时域资源的位置时，无需考虑发送所述HARQ-ACK信息的时域资源的位置。例如，NCR接收到上述第一控制信息或者或用于承载第一控制信息的DCI/PDCCH/PDSCH后，发送相应的HARQ-ACK信息，并且，该第一控制信息相关的第一(三)时间位置是承载该第一控制信息的时域资源或者物理信道(PDCCH/PDSCH)所在的时隙或最后一个时隙或最后一个符号，例如，在该第一控制信息是DCI时，该DCI由PDCCH承载，该第一(三)时间位置可以是承载DCI的PDCCH所在的子帧或时隙或最后一个时隙或最后一个符号，由此，发送HARQ-ACK信息的时域资源的位置和该第一控制信息中第一信息指示的时域资源的位置没有先后顺序的限定关系，也就是说，该第一控制信息中第一信息指示的时域资源的位置不受限于用于发送所述HARQ-ACK信息的时域资源的位置，反之亦然。
