技术领域
本申请涉及通信技术领域，尤其涉及一种传输参数管理方法、装置及电子设备
背景技术
新空口(New Radio，NR)下行(downlink，DL)发送采用的是开环功率控制机制。对于同步信号块(Synchronization Signal block，SSB/PSS/SSS/PBCH)和/或周期性的(periodic)信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)的发送，基站采用固定的每个资源单元的能量(Energy Per Resource Element，EPRE)，这些EPRE预先通知给用户设备(User Equipment，UE)，以便UE进行信号强度测量；对于控制资源集(CORESET)#0中的物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送，其EPRE控制在一个范围之内，基站会把该动态范围预先通知给UE；对于其他DL信道(channel)和/或信号(signaling)的发送，基站通过实现的方式决定发送功率，且相关信息不通知给UE。
NR上行(Uplink，UL)发送采用开环和闭环的功率控制方式，UE通过开环功控或闭环功控决定UL channel的发送功率。此外，UE的UL发送功率还受限于协议预定义的最大发送功率值，任何时候UE的UL发送功率都不可以超过该值。
但NR现有的功率控制机制没有考虑到IAB DU和MT间的功率谱密度(Power Spectral Density，PSD)不平衡的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员所获得的所有其他实施例，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用。
以下描述提供示例而并非限定权利要求中阐述的范围、适用性或者配置。可以对所讨论的要素的功能和布置作出改变而不会脱离本公开的精神和范围。各种示例可恰适地省略、替代、或添加各种规程或组件。例如，可以按不同于所描述的次序来执行所描述的方法，并且可以添加、省去、或组合各种步 骤。另外，参照某些示例所描述的特征可在其他示例中被组合。
请参见图1，图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是本申请实施例并不限定基站的具体类型和具体通信系统。
图2显示了一个自回传(integrated access backhaul,IAB)系统示意图。一个IAB节点包括分布式单元(Distributed Unit，DU)功能部分和移动终端(Mobile Termination，MT)功能部分。依靠MT，一个接入点(即IAB node)可以找到一个上游接入点(parent IAB node)，并跟上游接入点的DU建立无线连接，该无线连接被称为回传链路(backhaul link)。在一个IAB节点建立完整的回传链路后，该IAB节点打开其DU功能，DU会提供小区服务，即DU可以为用户设备(User Equipment，UE)提供接入服务。一个自回传回路包含一个归属(donor)IAB节点(或者称为IAB donor)，donor IAB节点有直接相连的有 线传输网。其中，Access为接入，Access IAB node为接入IAB节点，Intermediate IAB节点为中间IAB节点，cable transport为有线传输。
图3是一个IAB系统的CU-DU(Centralized Unit-Distributed Unit)结构图。在一个自回传回路中，所有的IAB节点的DU都连接到一个集中单元(Centralized Unit，CU)节点，由这一个节点通过F1协议(F1Application Protocol，或F1control protocol)对DU进行配置。CU通过无线资源控制(Radio Resource Control，RRC)协议，对MT进行配置。Donor IAB节点没有MT功能部分。
IAB系统的引入是为了解决接入点密集部署时，有线传输网部署不到位的情况。即在没有有线传输网络时，接入点可以依赖无线回传。
为了实现频分多路复用(Frequency-division multiplexing，FDM)和/或空分复用(Space Division Multiplexing，SDM)的资源复用，DU和MT的同时收发操作方式有以下几种：
(1)DU和MT同时发送(DU-TX&MT-TX)；或表示为，DU配置为下行(downlink，DL)，MT配置为上行(uplink，UL)；或表示为，DU进行DL发送，MT进行UL发送；
(2)DU和MT同时接收(DU-RX&MT-RX)；或表示为，DU配置为UL，MT配置为DL；或表示为，DU进行UL接收，MT进行DL接收；
(3)DU和MT同时一发一收(DU-TX&MT-RX)；或表示为，DU配置为DL，MT配置为DL；或表示为，DU进行DL发送，MT进行DL接收；
(4)DU和MT同时一发一收(DU-RX&MT-TX)；或表示为，DU配置为UL，MT配置为UL；或表示为，DU进行UL接收，MT进行UL发送。
NR DL发送采用的是开环功率控制机制。对于同步信号块(Synchronization Signal block，SSB/PSS/SSS/PBCH)和/或周期性的(periodic)信道状态信息-参考信号(Channel State Information-Reference Signal，CSI-RS)的发送，基站采用固定的每个资源单元的能量(Energy Per Resource Element，EPRE)，这些EPRE预先通知给UE，以便UE进行信号强度测量；对于控制 资源集(CORESET)#0中的物理下行控制信道(Physical Downlink Control Channel，PDCCH)发送，其EPRE控制在一个范围之内，基站会把该动态范围预先通知给UE；对于其他DL信道(channel)和/或信号(signaling)的发送，基站通过实现的方式决定发送功率，且相关信息不通知给UE。
NR UL发送采用开环和闭环的功率控制方式，UE通过开环功控或闭环功控决定UL channel的发送功率。此外，UE的UL发送功率还受限于协议预定义的最大发送功率值，任何时候UE的UL发送功率都不可以超过该值。
但NR现有的功率控制机制没有考虑到IAB DU和MT间的功率谱密度(Power Spectral Density，PSD)不平衡的问题。
针对IAB DU和MT同时接收的情况，如图4所示，可以由IAB node向parent node发送辅助信息，以辅助parent node进行下行功控，这种方式可以理解为parent node进行闭环(close loop)下行功率控制(DL power control)。或者，如图5所示，Parent node可以向IAB节点发送辅助信息，以辅助IAB节点进行上行功控。这种方式可以理解为，parent node进行开环(open loop)DL power control，辅助信息即为功控参数。或者，如图6所示，IAB node可以向parent node发送辅助信息，以辅助parent node进行上行功控。或者，如图7所示，Parent node可以向IAB节点发送辅助信息，以辅助IAB节点进行下行功控。

可选地，用现有的twoPUSCH-PC-AdjustmentStates(高层参数)，CU配置IAB节点其中的一个State用于某种复用调度模式下，对其child node MT或UE进行功控。
可选地，除了现有的twoPUSCH-PC-AdjustmentStates外，CU配置一个或多个新的PUSCH/PUCCH功控态(power control state/power adjustment state)，用于DU PUSCH/PUCCH和MT PDSCH/PDCCH同时传输时，IAB node对child node MT或UE的上行功控。所述方法可以适用于DU PUSCH/PUCCH和MT PUSCH/PUCCH同时传输的情况。另外，可以在DCI中引入一个新的指示域指示当前调度是否使用新的或某一个/多个或某一种/多种PUSCH  power control state。
可选地，IAB节点在进行上行功率调整/控制时，除了功控命令，还发送一个附加的功率调整参数调整child node MT或UE的上行发送功率，这个附加的功率调整参数仅对当前调度的PUSCH有效或者对一个power control state有效。
