Definitions

  • This application relates to the field of communication.
  • Coverage issues are a fundamental issue in cellular network deployment.
  • Mobile operators employ different types of network nodes in their deployments to provide comprehensive coverage.
  • a common full-stack cell deployment is ideal, but it is not always feasible (eg, when there is no backhaul link) or economical. Therefore, mobile operators consider using new types of network nodes to increase the flexibility of network deployment.
  • NR rel-17 introduces a radio frequency repeater (RF repeater), which is used to increase the coverage area of NR's cellular network deployment.
  • RF repeaters are usually non-generative and simply amplify and forward (AF) all received signals.
  • RF repeaters are usually full-duplex and cannot distinguish between upstream and downstream transmissions. Its advantages are low cost, simple deployment, and no delay. Its disadvantage is that it is possible to amplify the noise together, thus increasing the interference to the signal.
  • NR's radio frequency repeater needs to regulate radio frequency and electromagnetic compatibility (EMC) requirements, and also needs to consider the frequency bands of FR1 (FDD and TDD) and FR2 (TDD).
  • EMC radio frequency and electromagnetic compatibility

  • the control link can be based on the existing Uu interface.
  • the MT applies these configuration information to the RU (that is, the AF module) through the internal operation of the intelligent repeater.
  • the access link from gNB to ordinary UE has undergone signal amplification and forwarding by intelligent repeater, so it is called AF link, and it can also be called data path.
  • the repeater is transparent to the UE, and the UE does not know the existence of the repeater.

Description

功率相关信息的上报装置及方法 技术领域
本申请涉及通信领域。
背景技术
覆盖问题是蜂窝网络部署的一个根本问题。移动运营商在其部署中采用不同类型的网络节点来提供全面覆盖。普通的全协议栈的小区部署是最理想的，但是它并不总是可行的(例如，当没有回传链路时)或者经济的。因此，移动运营商考虑使用新的类型的网络节点来增加网络部署的灵活性。
NR rel-17引入了射频中继器(RF repeater)，用于增加NR的蜂窝网络部署的覆盖面积。射频中继器通常是非自生的(non-generative)，只是简单地将所有收到的信号进行放大并转发(amplify and forward，AF)。射频中继器通常是全双工的，不能区分上行和下行传输。它的优点是成本低，部署简单，不增加时延。它的不足之处是有可能将噪音一起放大，从而增加了对信号的干扰。
NR的射频中继器需要规范射频和电磁兼容(electromagnetic compatibility，EMC)的需求，还需要考虑FR1(FDD和TDD)和FR2(TDD)的频段。射频中继器不需要对终端设备(UE)执行自适应波束成形。
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
为了优化系统性能，包括可能的减轻干扰和进一步提高覆盖，智能中继器(smart repeater)被提出并被认为是一个用来提升网络拓扑的有效方案。智能中继器的主要优点有：比传统中继(relay)，IAB-DU(integrated access and backhaul-distributed unit)和gNB更加简单的协议栈；通过gNB的侧面控制(side control)来实现智能操作，比如动态改变中继器的发送和接收(TX/RX)。
智能中继器可以分为两个部分，一部分用来实现部分UE的功能，这部分可以叫做MT(mobile termination，移动终端)，其和网络设备(例如gNB)进行通信。另外一部分实现无线射频功能，也就是中继器的放大转发功能，这部分可以称为RU(radio unit，无线单元)。
gNB和MT之间的链路是一个控制链路或控制路径，也是前向(fronthaul)链路。通过该控制链路，gNB可以通过侧面控制信息，例如TDD配置、开关信息、RU的波束成形信息等来配置智能中继器。该控制链路可以基于已有的Uu接口。MT将这些配置信息通过智能中继器内部操作运用到RU(也就是AF模块)中。
gNB到普通UE的接入链路经历了智能中继器的信号放大转发，因此称为AF链路，也可以叫数据路径。中继器对UE来讲是透明的，UE并不知道中继器的存在。该数据路径(例如FR2)携带了从UE来的或者发给UE的模拟上行或下行信号。该路径本质上是一个模拟信号穿过(pass through)。数据路径完全被gNB(DU)通过控制路径来进行控制。
在UE进行上行传输时，除了完成物理层功率控制之外，需要将UE的功率余量上报(power headroom report,PHR)到网络。功率余量(power headroom，PH)表示当前UE的BWP(bandwidth part，部分带宽)中发射功率与最大允许发射功率能力之间的差值。
针对UE的功率余量上报，5G定义了3种PH类型：Type 1 PH是当前终端最大发射功率和估计的PUSCH(Physical Uplink Shared CHannel，物理上行共享信道)传输功率的差值；Type 2 PH是当前终端最大发射功率和估计的PUCCH(Physical Uplink Control CHannel，物理上行控制信道)和PUSCH传输功率之和的差值；Type 3 PH是当前终端最大发射功率和估计的SRS(Sounding Reference Signal，探测参考信号)传输功率的差值。
发明人发现，在例如智能中继器等的网络节点中，终端(MT)在功率余量上报时，只能上报MT自己的功率余量，不能上报RU部分的功率余量。这样，不利于网络设备对无线单元(RU)进行功率控制，从而影响网络性能。
为了解决上述问题中的一个或多个，本申请实施例提供一种功率相关信息的上报装置及方法，第一网络节点的第一模块上报第二模块的功率相关信息，这样，网络设备能够根据上报的功率相关信息对第二模块进行有效的功率控制，从而实现网络性能 的优化。

另外，在本申请实施例中，第二模块的上行功率相关信息和下行功率相关信息可以同时进行上报，例如，包含在同一个PHR中进行上报；或者，第二模块的上行功率相关信息和下行功率相关信息也可以分别进行上报，例如分别包含在不同的PHR中进行上报。
在本申请实施例中，例如，针对上行传输有相应的功率余量，可以称为上行功率余量；针对下行传输有相应的功率余量，可以称为下行功率余量。
例如，针对上行传输有相应的增益，可以称为上行增益；针对下行传输有相应的增益，可以称为下行增益。
例如，针对上行传输有相应的发射功率，可以称为上行发射功率；针对下行传输有相应的发射功率，可以称为下行发射功率。
也就是说，上行功率相关信息可以包括上行功率余量、上行增益以及上行发射功率中的至少一个，下行功率相关信息可以包括下行功率余量、下行增益以及下行发射功率中的至少一个。
在本申请实施例中，第一模块除了上报第二模块的功率相关信息(例如上行功率相关信息和/或下行功率相关信息)，还可以上报该第一模块的功率相关信息。
在本申请实施例中，该第一模块可以使用相同的MAC(medium access control)CE(control element)上报该第一模块的功率相关信息和该第二模块的功率相关信息，或者，该第一模块也可以使用不相同的MAC CE上报该第一模块的功率相关信息和该第二模块的功率相关信息。
在本申请实施例中，可以是在满足一定触发条件时，上报第二模块的功率相关信息。
下面，基于上报第二模块的功率余量、增益以及发射功率分别进行具体的说明
首先，对上报功率余量的情况进行具体的说明。
在本申请实施例中，例如将第二模块的上行功率余量称为第一功率余量，将第二模块的下行功率余量称为第二功率余量。
该第一功率余量和该第二功率余量可以是相同类型的功率余量，或者也可以是不同类型的功率余量。
例如，第一功率余量是Type 4功率余量(Type 4 PH)，第二功率余量是Type 5功率余量(Type 5 PH)，或者，第一功率余量和第二功率余量均为Type 4功率余量(Type 4 PH)。另外，Type 4功率余量(Type 4 PH)以及Type 5功率余量(Type 5 PH)只是一个示例性的名称，第一功率余量和第二功率余量也可以采用其他名称来表示其类型。
在本申请实施例中，该第一功率余量表示当前第二模块在一个频段内的最大发射功率和估计的上行传输功率的差值，和/或，该第二功率余量表示当前该第二模块在一个频段内的最大发射功率和估计的下行传输功率的差值。
例如，PH＝P CMAX-P RU，
其中，PH表示第一功率余量或第二功率余量，P CMAX表示当前第二模块在一个频段内的最大发射功率，P RU表示估计的上行传输功率或下行传输功率。
在本申请实施例中，P RU可以是根据功率控制式计算得到，也可以由第二模块在某个时刻或时段测量得到。当PH为正值时，其表示第二模块还有多少传输功率可以使用；当PH为负值时，其表示所计算的传输功率已经超过第二模块允许的最大传输功率。
在本申请实施例中，根据第二模块的实现情况，该“一个频段”可以有不同的具体含义。例如，该第一功率余量和/或该第二功率余量可以针对一个小区(cell)，或者小区的一个BWP，或者一个载频(carrier)，或者一个通带(pass band)。
这样，通过cell ID，或者BWP ID，或者carrier ID，或者pass band ID，能够反映出该频段的起始频点或中心频点，以及带宽。
在本申请实施例中，在步骤301中，例如，该第一模块将该第二模块的至少一个上行功率余量和该上行功率余量对应的至少一个频段标识(ID)上报给网络设备，和/或，该第一模块将该第二模块的至少一个下行功率余量和该下行功率余量对应的至少一个频段标识(ID)上报给网络设备。
也就是说，第一模块可以上报一个或多个上行功率余量以及相应的频段ID，和/或，一个或多个下行功率余量以及相应的频段ID。
例如，该频段ID是cell ID，或者BWP ID，或者carrier ID，或者pass band ID。
在本申请实施例中，在步骤301中，该第一模块还可以将该上行功率余量对应的至少一个频段的该第二模块的最大输出功率(P CMAX)上报给该网络设备，和/或，该第一模块还可以将该下行功率余量对应的至少一个频段的该第二模块的最大输出功率(P CMAX)上报给该网络设备。
在步骤301中，该第一模块可以通过第一MAC CE(control element，控制单元)上报该第二模块的功率余量。
在本申请实施例中，该第一MAC CE可以包含至少一个小区ID以及与该小区ID对应的上行功率余量和/或下行功率余量。
例如，当第二模块分配了一个或多个小区(cell)ID，且这些cell ID和第一模块的cell ID不重叠时，第二模块的上行功率余量可以和第一模块的功率余量一起上报 给网络设备，也就是说，可以利用已有的PHR MAC CE来上报第一模块和第二模块的功率余量。
例如，已有的单条目或多条目的PHR MAC CE可以不变。网络设备通过cell ID来区分该cell ID对应的功率余量是针对第一模块的还是针对第二模块的。
例如，当一个cell ID对应的是第二模块时，相应的条目包含的是第二模块的P CMAX和Type 4 PH。
在本申请实施例中，该第一模块可以使用相同的MAC CE上报该第一模块的功率相关信息和该第二模块的功率余量，也可以使用不同的MAC CE上报该第一模块的功率相关信息和该第二模块的功率余量。
例如，当使用相同的MAC CE上报该第一模块的功率余量和该第二模块的功率余量时，在该MAC CE中，第一小区对应的功率余量是该第一模块的功率余量，第二小区对应的功率余量是该第二模块的功率余量，该第二小区包含该第二模块的工作频段。也就是说，例如，当某上报的服务小区含有激活的第二模块(例如RU)的工作频段时，可上报第二模块在该工作频段的Type 4 PH。
另外，在本申请实施例中，该第一模块的至少一个类型的功率余量或该第二模块的至少一个类型的功率余量具有上报的优先级。也就是说，为每个服务小区上报最多一种功率余量，且根据这些功率余量的优先级来确定上报哪种功率余量，即，上报优先级高的功率余量。这样，能够减少上报信令开销。
在本申请实施例中，可以是，当满足第一条件时，该第一网络节点的第一模块上报第二模块的功率余量。
例如，该第一条件包括以下条件中的至少一个：
该第二模块在一个频段被激活或重激活；
第一定时器超时，同时，该第一模块获得了用于新数据传输的上行资源，并且自从上一次功率余量上报后至少一个用于路损参考的且激活的下行BWP不是休眠BWP的服务小区的路损变化量超过第一阈值；
第二定时器超时；
RRC层对该第一模块配置或重配置了功率余量上报(PHR)功能(不包含关闭PHR)；
网络侧激活了一个配置有上行的且firstActiveDownlinkBWP-Id没有被设为休眠的 BWP的辅小区(SCell)；
主辅小区(PSCell)添加；
该第一定时器超时，MAC实体有用于新数据传输的上行资源，并且任何一个MAC实体中配置有上行的激活服务小区满足如下条件：该激活服务小区有上行资源分配或者有PUCCH传输，并且该激活服务小区由于功率管理所需的功率回退相当于上次在MAC实体分配给该激活服务小区的上行资源或者PUCCH上传输的功率余量上报时的变化值超过第二阈值；以及
在任意配置有上行的MAC实体的辅小区上将激活BWP从休眠BWP切换至非休眠的下行BWP。
例如，该第一定时器可以称作功率余量上报禁止定时器(phr-ProhibitTimer)，该第二定时器可以称作功率余量上报周期定时器(phr-PeriodicTimer)。
例如，该第一阈值是网络配置的门限phr-Tx-PowerFactorChange。
在本申请实施例中，由于第一网络节点的第二模块同时进行上行和下行的放大和转发，因此针对下行传输也会有功率余量。对于下行功率余量，即第二功率余量，具体说明如下。
在本申请实施例中，可以为第二模块定义一个新的针对下行AF传输的PH类型，例如是Type 5 PH。这个新的类型的PH表示当前第二模块在某个频段内的最大发射功率和估计的下行传输功率的差值。Type 5 PH除了是针对下行，其他相关内容与Type4 PH类似。
在某些场景下，第二模块(例如RU模块)也会发送自己的参考信号，以便于UE进行测量。
这些参考信号例如可以包括SSB(Synchronization Signal Block，同步信号块)、CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)以及下行SRS中的至少一个。
这些信号是第二模块自己产生的，不是通过AF链路传输的，它们的传输所用的功率控制也可以不同。
在本申请实施例中，可以给这些参考信号定义不同类型的功率余量。
例如，定义Type 6 PH为当前第二模块最大发射功率和估计的SSB传输功率的差值；定义Type 7 PH为当前第二模块最大发射功率和估计的CSI-RS传输功率的差值； 定义Type 8 PH为当前第二模块最大发射功率和估计的下行SRS传输功率的差值。
在本申请实施例中，该第二功率余量包括真实功率余量和虚拟功率余量。
例如，Type 6 PH、Type 7 PH和Type 8 PH都可以分为真实PH和虚拟PH。当有相应的参考信号传输时，上报真实的PH到网络设备，当没有相应的参考信号传输时，上报预先约定的参考信号格式计算一个PH给网络设备，称为虚拟PH。
在本申请实施例中，可以通过第一网络节点的第一模块将第二模块的一个或多个下行PH和对应的一个或多个频段ID上报给基站，比如通过MAC CE来上报。在上报某频段PH的同时，还可以包含对应的该频段的P CMAX值。
为了减少上报信令开销，可以为每个频段上报最多一种PH。
在本申请实施例中，第二模块的第二功率余量的至少一个类型的功率余量具有上报的优先级，即，可以将第二模块的第二功率余量的不同类型的PH进行优先级排序，在某频段同时有多个PH的时候按优先级汇报优先级高的PH。
例如，一种优先级排序为：Type 5 PH>真实的Type 6 PH>真实的Type 7 PH>真实的Type 8 PH>虚拟的Type 6 PH>虚拟的Type 7 PH>虚拟的Type 8 PH。
在本申请实施例中，智能中继器中的MT模块(第一模块)和RU模块(第二模块)的数据传输可以采用多种方式。以下以第一网络节点是智能中继器为例，针对具体的场景进行说明。
例如，MT模块和RU模块可以采用频分复用(frequency division multiplexing，FDM)的方式，也就是MT模块和RU模块采用不同的载频。
图4是本申请实施例1的智能中继器的一示意图。如图4所示，智能中继器400包括MT模块和RU模块，MT模块和RU模块采用不同的载频，即互为带外(out-of-band)通信。在智能中继器中有两个射频链(RF chain)，一个用于MT模块，另一个用于RU模块。RU模块作为放大器工作的频点和MT模块与网络设备通信用的频点总是不同，或者总是相隔足够的频率范围。在这种情况下，智能中继器400的AF(放大并转发)功能部分不会被MT模块发送给或接收网络设备的信号所影响。
对于智能中继器，网络设备也需要知道RU模块的上行传输功率余量，以便对RU模块进行上行功率控制。由于RU模块是非自生的中继器，并不对UE或者网络设备的信号进行编解码，因此RU模块不会知道自己转发的数据是属于什么物理信道，也就是5G定义的3种PH类型都不适用于RU模块的PHR。
在本申请实施例中，例如，MT模块上报的RU模块的功率余量是Type 4 PH，其表示当前RU模块在某个频段内的最大发射功率和估计的上行传输功率的差值。具体的计算方式可参见上面关于上行功率余量的内容，此处不再重复说明。
类似的，如果RU的上行功率余量报告(PHR)被触发，则通过MT模块将RU模块的一个或多个上行PH和对应的一个或多个频段ID上报给网络设备。另外，如果RU模块也分配了一个或多个小区ID(cell ID)，这些小区ID和MT模块的小区ID不重叠，那么RU模块的上行PH可以和MT模块的PH一起上报给网络设备，也就是利用已有的PHR MAC CE来上报MT模块和RU模块的PH。已有的单条目和多条目的PHR MAC CE可以不变。网络设备可以通过cell ID来区分该cell ID对应的PH是针对MT模块的还是针对RU模块的。如果某cell ID对应的是RU模块，则相应的条目包含的是RU模块的P CMAX和Type 4 PH。
又例如，MT模块和RU模块可以采用时分复用(time division multiplexing，TDM)的方式，也就是MT模块和RU模块在不同的时段进行通信。图5是本申请实施例1的智能中继器的另一示意图。如图5所示，智能中继器500包括MT模块和RU模块，MT模块和RU模块在不同的时段进行通信，MT模块和RU模块采用相同的频段，即两者为带内(in-band)通信。在这种结构下，当MT模块在收发和网络设备的信号时，RU模块会暂停或者挂起工作。当RU模块在进行放大和转发时，MT模块会停止通信。
图6是本申请实施例1的智能中继器的又一示意图。如图6所示，智能中继器600包括MT模块和RU模块，MT模块和RU模块采用相同的频段，即两者为带内(in-band)通信，但是MT模块和RU模块并不采用时分复用的传输方式。MT模块的上行或下行信号和中继器的AF信号合并在一起进行传输。
在图5和图6示出的场景中，MT模块和RU模块都在同频段工作，因此可以重用PHR MAC CE来进行PH上报，也就是MT模块照常使用PHR MAC CE来上报与自身相关的PH，例如Type 1和Type 3 PH。
但是，如果某小区包含有RU模块的工作频段，该小区可以为RU模块定义Type 4 PH，有关Type 4 PH的具体内容可以参考前面的记载，此处不再重复说明。
另外，如前所述，和传统的PHR MAC CE不同，MT模块还可以同时上报RU模块的Type 4 PH。方法是仍然采用单条目或多条目的PHR MAC CE，当某上报的服务 小区含有激活的RU模块工作频段时，可上报RU模块在该工作频段的Type 4 PH。
另外，如前所述，MT模块的至少一个类型的功率余量或RU模块的至少一个类型的功率余量具有上报的优先级。也就是说，为每个服务小区上报最多一种功率余量且根据这些功率余量的优先级来确定各小区上报哪种功率余量，即，上报优先级高的功率余量。这样，能够减少上报信令开销。
例如，对于一个小区，如果该小区含有RU模块的工作频段，那么可以上报MT模块的功率余量，也可以上报RU模块的功率余量；而如果该小区不含有RU模块的工作频段，则上报MT模块的功率余量。并且，在MT模块和RU模块有多个类型的功率余量的情况下，根据优先级来确定该小区上报哪种功率余量。
例如，功率余量的优先级排序为：真实的(actual)Type 1 PH>Type 4 PH>真实的Type 3 PH>虚拟的(virtual)Type 1 PH>虚拟的Type 3 PH。
以上，对上报功率余量的情况进行了具体的说明。接着，对上报第二模块的增益的情况进行具体的说明。
在本申请实施例中，该第一模块可以将该第二模块在至少一个频段的增益上报给网络设备。
例如，该增益针对一个小区(cell)，或者小区的一个BWP，或者一个载频(carrier)，或者一个通带(pass band)。
例如，该第二模块的增益包括该第二模块的上行增益和/或下行增益，该上行增益是指上行传输的放大增益，下行增益是指下行传输的放大增益。
在本申请实施例中，第一网络节点通常是为了增强小区覆盖，因此所使用的增益通常是用来补偿网络设备到第一网络节点的路径损耗，因此上下行传输可能采样同样的放大增益。在这种情况下，可以只上报各频段的一个通用增益，表明上下行同时使用该增益。
在本申请实施例中，该第一模块可以通过第二MAC CE或RRC信令上报该第二模块的增益。
例如，第二MAC CE称为GR(Gain Report)MAC CE。
该RRC信令是第一模块到网络设备的RRC信令。
在本申请实施例中，该第二MAC CE或该RRC信令可以包括频段标识(ID)以及与该频段标识对应的上行增益和/或下行增益。
在本申请实施例中，该第二MAC CE或该RRC信令还可以包括与该频段对应的最大增益。
在本申请实施例中，例如，当满足第二条件时，该第一网络节点的第一模块上报第二模块的增益。
例如，该第二条件包括以下条件中的至少一个：
第三定时器超时，同时，该第一模块获得了用于新数据传输的上行资源，并且，该第二模块在一个频段的增益与上次功率上报的增益的变化值大于或等于第三阈值；
第四定时器超时；以及
RRC层对该第一模块配置或重配置了增益上报(GR)功能(不包含关闭GR)。
例如，该第三定时器例如可以称作增益上报禁止定时器(gr-ProhibitTimer)，该第四定时器例如可以称作增益上报周期定时器(gr-PeriodicTimer)。
在本申请实施例中，增益上报禁止定时器是为增益上报设置的一个最小上报间隔，也就是定时器运行时不能进行增益上报，避免上报过渡频繁。增益上报周期定时器是设置的最大上报间隔，也就是即使没有其他事件触发，到一定时间周期也需要上报。
例如，该第三阈值由网络设备通过RRC信令对第一模块进行配置。
以上，对上报增益的情况进行了具体的说明。接着，对上报第二模块的发射功率的情况进行具体的说明。
在本申请实施例中，上报的发射功率可以是第二模块在某一时刻的发射功率，也可以是第二模块在某一段时间内的平均发射功率。
在本申请实施例中，第二模块的发射功率可以包括第二模块的上行发射功率和/或下行发射功率。
在本申请实施例中，该第一模块可以通过第三MAC CE或RRC信令上报该第二模块的发射功率。
例如，第三MAC CE称为PR(Powr Report)MAC CE。
例如，该第三MAC CE或该RRC信令包括频段标识(ID)以及与该频段标识对应的上行发射功率和/或下行发射功率。该第三MAC CE或该RRC信令还可以包括与该频段对应的最大发射功率。
在本申请实施例中，例如，当满足第三条件时，该第一网络节点的第一模块上报 第二模块的发射功率。
例如，该第三条件包括以下条件中的至少一个：
第五定时器超时，同时，该第一模块获得了用于新数据传输的上行资源，并且，该第二模块在一个频段的发射功率与上次功率上报的发射功率的变化值大于或等于第四阈值；
第六定时器超时；以及
RRC层对该第一模块配置或重配置了功率上报(PR)功能(不包含关闭PR)。
例如，该第五定时器称作功率上报禁止定时器(pr-ProhibitTimer)，该第六定时器称作功率上报周期定时器(pr-PeriodicTimer)。
例如，该第四阈值由网络设备通过RRC信令对第一模块进行配置。
由上述实施例可知，第一网络节点的第一模块向网络设备上报第二模块的功率相关信息，这样，网络设备能够根据上报的功率相关信息对第二模块进行有效的功率控制，从而实现网络性能的优化。
实施例2
本申请实施例2还提供一种功率相关信息的接收方法，该方法应用于网络设备侧。该方法对应于实施例1中的第一网络节点侧的功率相关信息的上报方法，相同的内容不再重复说明。
图7是本申请实施例2的功率相关信息的接收方法的一示意图。如图7所示，该方法包括：
步骤701：从第一网络节点的第一模块接收该第一网络节点的第二模块的功率相关信息。
例如，该功率相关信息包括该第二模块的上行功率相关信息和/或下行功率相关信息。
例如，该功率相关信息包括该第二模块的功率余量、增益以及发射功率中的至少一个。
例如，该第一模块是终端设备(mobile terminal，MT)模块，该第二模块是无线单元(radio unit，RU)模块。
例如，该第一网络节点是智能中继器(smart repeater，SR)。
上述方法的具体实现以及有关功率相关信息的具体内容可以参照实施例1中的 记载，此处不再具体说明。
由上述实施例可知，第一网络节点的第一模块向网络设备上报第二模块的功率相关信息，这样，网络设备能够根据上报的功率相关信息对第二模块进行有效的功率控制，从而实现网络性能的优化。

本申请实施例3提供了一种功率相关信息的上报装置，该装置设置于第一网络节点。该第一网络节点包括第一模块和第二模块。由于该装置解决问题的原理与实施例1的方法类似，因此其具体的实施可以参照实施例1所述的方法的实施，内容相同或相关之处不再重复说明。
