相关申请的交叉引用
本申请要求于2020年10月16日提交的申请号为202011112047.9，发明名称为“功率控制方法、网络设备、终端、装置及存储介质”的中国专利申请的优先权，其通过引用方式全部并入本文。
技术领域
本公开涉及通信技术领域，尤其涉及一种功率控制方法、网络设备、终端、装置及存储介质。
背景技术
物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的功率控制过程是对PUSCH的发射功率进行调整，目的是补偿路径损耗、阴影衰落以及快衰落等的影响；同时，PUSCH的功率控制也用于控制小区间的干扰水平。
现有技术中，PUSCH功率控制主要由开环和闭环两个部分组成。在闭环功率控制过程中不可缺少的一个重要部分就是传输功率控制(Transmission Power Control,TPC)命令更新。通过更新TPC命令进行PUSCH功率控制。
但是，现有技术中的方案会导致因为过高的发送功率或者过低的发送功率并没有合适的调制与编码策略(Modulation and Coding Scheme,MCS)匹配其性能，因为自适应调制编码(Adaptive Modulation and Coding,AMC)中MCS等级存在上限和下限。MCS等级的上限，导致并不是随着功率提升一定会带来性能提升，反而带来干扰增加的问题；MCS等级的下限，导致过低的功率并没有合适的MCS与其匹配，造成误块率(Block Error Rate,BLER)增大的问题。

具体实施方式
PUSCH的功率控制过程是对PUSCH的发射功率进行调整，目的是补偿路径损耗、阴影衰落以及快衰落等的影响；同时，PUSCH的功率控制也用于控制小区间的干扰水平。PUSCH功率控制主要由开环和闭环两个部分组成。在闭环功率控制过程中不可缺少的一个重要部分就是TPC命令更新。
现有标准中规定了TPC命令需要包含于具有下行控制信息(Downlink Control Information,DCI)格式(Format)0的物理下行控制信道(Physical Downlink Control Channel,PDCCH)中，或包含于DCI格式3/3A的PDCCH中并与其他TPC命令联合编码(此时PDCCH的循环冗余校验(Cyclic Redundancy Check,CRC)校验比特由TPC-PUSCH-RNTI进行加扰)。当前的PUSCH功率控制调整状态用f(i)表示。
若通过无线资源控制(Radio Resource Control，RRC)层通知的UE专属参数(积使能参数Accumulation-enabled)开启了累积值方式的功率控制，或者TPC命令字δ PUSCH包含在DCI Format0并且CRC校验比特采用临时(Temporary)C-RNTI加扰的PDCCH中，则f(i)的计算公式如下：
f(i)＝f(i-1)+δ PUSCH(i-K PUSCH)
其中，f(i)为当前的PUSCH功率控制调整状态，δ PUSCH(i-K PUSCH)指i-K PUSCH子帧上的DCI格式0或3/3A发送的TPC命令，f(0)是f(i)重置之后的初始值。
K PUSCH的值的确定方法如下：
对于频分双工(Frequency Division Duplex,FDD)，K PUSCH＝4；
对于时分双工(Time Division Duplex,TDD)上行/下行(UL/DL)配置(Configuration)1-6时，不同TDD UL/DL配置的K PUSCH取值如 表1所示。
对于TDD UL/DL配置0：
当由PDCCH DCI格式0调度的PUSCH传输位于子帧2或7且DCI中的UL index信息域的低比特位为1时，K PUSCH＝7；
对于其它情况的PUSCH传输，K PUSCH的值根据表1确定。
表1不同TDD UL/DL配置的K PUSCH取值
Figure PCTCN2021121183-appb-000001
UE在每个非非连续接收(Discontinuous Reception,DRX)子帧用该UE的C-RNTI或SPS-RNTI(半持久调度RNTI)尝试解码一个DCI Format0的PDCCH，同时也用该UE的TPC-PUSCH-RNTI尝试解码一个DCI Format3/3A的PDCCH。
如果UE在同一子帧内同时检测到DCI Format0和DCI Format3/3A的PDCCH，则UE只使用由DCI Format0给出的TPC命令δ PUSCH。
当在某一子帧中没有解码出TPC命令、或UE处于DRX状态、或在TDD模式下第i个子帧不是上行子帧时，δ PUSCH＝0dB。
当累积修正值δ PUSCHdB包含在具有DCI格式0的PDCCH时，其调整值见表2；但是，如果DCI Format0的功能是SPS激活或SPS释放，则δ PUSCH＝0dB。

当累积修正值δ PUSCHdB包含在具有DCI格式3/3A的PDCCH时，其调整值集合包括两种：集合1由表2给出、集合2由表3给出，具体选择哪个集合由RRC层参数TPC-Index的比特数决定。

若UE达到最大发射功率，则“正”的TPC命令不进行累积；
若UE达到最小发射功率，则“负”的TPC命令不进行累积；
处于如下状态的UE需要重新设置TPC命令的累积：
当P O_UE_PUSCH改变时；
当收到随机接入响应消息时(处于同步/重同步状态)。
若通过RRC层配置的UE专属参数Accumulation-enabled未开启累积值方式时，UE处于绝对值闭环方式，f(i)＝δ PUSCH(i-K PUSCH)，其中，δ PUSCH(i-K PUSCH)由子帧i-K PUSCH中的具有DCI格式0的PDCCH指示。
K PUSCH的值按如下方式确定：
对于FDD，K PUSCH＝4；
对于TDD UL/DL配置1-6，K PUSCH值如表1所示；
对于TDD UL/DL配置0：
当由PDCCH DCI格式0调度的PUSCH传输位于子帧2或7且DCI中的UL index信息域的低比特位为1时，那么K PUSCH＝7；
对于其它情况的PUSCH传输，K PUSCH由表1给出。
绝对值方式下的δ PUSCH由具有DCI格式0的PDCCH指示，δ PUSCH取值如表2所示；如果DCI Format0的功能是SPS激活或SPS释放则δ PUSCH＝0dB。
如果某个子帧中没有解码出具有DCI format0的PDCCH、或UE处于DRX状态、或在TDD模式下第i个子帧不是上行子帧时，f(i)＝f(i-1)。
对于两种TPC调整值f(*)计算方法(累积值方式或绝对值方式)，其初始值设置为：
P O_UE_PUSCH配置发生改变时，f(i)＝0。
否则，通过如下公式进行计算：
f(0)＝ΔP rampup+δ msg2
其中，δ msg2是随机接入响应消息中指示的TPC命令字，用于调度的PUSCH的TPC命令字δ msg2的取值如表4所示。ΔP rampup由RRC层配置，对应于从首次至最后一次preamble传输之间总的功率爬升量。

Figure PCTCN2021121183-appb-000004
(1)P CMAX,f,c(i)：UE计算的最大发射功率。UE结合高层参数配置的最大发射功率及应用场景和自身射频要求确定的输出功率。
(2)P O_PUSCHb,,f,c(j)：UE基准发射功率，由高层配置的小区级标称功率参数P O_NOMINALP_USCH,f,c(j)和UE级标称功率参数P O_UE_PUSCH,b,f,c(j)组成。J是与业务相关的索引，取值如下：
1.如果没有给UE配置P0-PUSCH-AlphaSet或是通过RAR UL许可调度的PUSCH传输，j＝0，P O_UE_PUSCH,b,f,c(0)＝0并且P O_NOMINALP_USCH,f,c(0)＝P O_PRE+Δ PREAMBLE_Msg3，其中前导目标接收功率P O_PRE和msg3前导偏移Δ PREAMBLE_Msg3由高层参数preambleReceivedTargetPower、msg3-DeltaPreamble指定，如果没有给出msg3-DeltaPreamble配置，Δ PREAMBLE_Msg3＝0dB。
2.如果是通过配置的授权配置参数ConfiguredGrantConfig配置的PUSCH传输，j＝1，P O_NOMINALP_USCH,f,c(1)P O_NOMINALP_USCH,f,c(1)由 p0-NominalWithoutGrant提供，或如果p0-NominalWithoutGrant没有提供配置，P O_NOMINALP_USCH,f,c(1)＝P O_NOMINALP_USCH,f,c(0)并且P O_UE_PUSC,Hb,f,c(1)从免调度配置IE ConfiguredGrantConfig的P0-PUSCH-AlphaSetId p0值配置索引获取p0-PUSCH-Alpha配置。其中，NominalWithoutGrant为没有授权的Po-nominal，AlphaSetId为alpha参数集合ID。
3.当j∈{2,...,J-1}＝S J,P O_NOMINALP_USCH,f,c(j)由高层参数p0-NominalWithGrant指定，或没有配置p0-NominalWithGrant时，P O_NOMINALP_USCH,f,c(j)＝P O_NOMINALP_USCH,f,c(0)，P O_UE_PUSC,Hb,f,c(j)由p0-PUSCH-AlphaSetId指定p0值配置索引获取p0-PUSCH-Alpha配置。
1)如果配置了多组高层参数SRI-PUSCH-PowerControl，每组中都关联了一个p0-PUSCH-AlphaSetId，并且如果DCI format 0_1包含一个SRI域，UE根据SRI-PUSCH-PowerControlId选择一组SRI-PUSCH-PowerControl配置，再从SRI-PUSCH-PowerControl配置中获取p0-PUSCH-AlphaSetId，再根据ID对应的P0-PUSCH-AlphaSet确定P O_UE_PUSC,Hb,f,c(j)。其中，PowerControl为功率控制。
2)如果是通过DCI format 0_0或没有SRI域的DCI format 0_1调度PUSCH传输，或者没有为UE提供SRI-PUSCHPowerControl，那么j＝2，并且从p0-AlphaSets列表的第一个P0-PUSCH-AlphaSet获取P O_UE_PUSC,Hb,f,c(j)。
(3)α b,f,c(j)：
1.j＝0时，α b,f,c(0)取值为高层参数msg3-Alpha，如果没有配置该高层参数，α b,f,c(0)＝1。
2.j＝1时，α b,f,c(1)取值为高层参数ConfiguredGrantConfig中p0-PUSCH-Alpha配置的ID对应的P0-PUSCH-AlphaSet中alpha值；
3.j∈S J时，α b,f,c(j)取值为p0-PUSCH-AlphaSetId对应的P0-PUSCH-AlphaSet中alpha值，p0-PUSCH-AlphaSetId确定方法如下：
1)如果配置了多组高层参数SRI-PUSCH-PowerControl，每组中 都关联了一个p0-PUSCH-AlphaSetId，并且如果DCI format 0_1包含一个SRI域，UE根据SRI-PUSCH-PowerControlId选择一组SRI-PUSCH-PowerControl配置，再从SRI-PUSCH-PowerControl配置中获取p0-PUSCH-AlphaSetId，再根据ID对应的P0-PUSCH-AlphaSet确定α b,f,c(j)；
2)如果是通过DCI format 0_0或没有SRI域的DCI format 0_1调度PUSCH传输，或者没有为UE提供SRI-PUSCHPowerControl，那么j＝2，并且从p0-AlphaSets列表的第一个P0-PUSCH-AlphaSet获取α b,f,c(j)。

在第i个PUSCH传输机会上的资源块数量；
(5)PL b,f,c(q d)：UE使用索引为q d参考信号测量的下行激活BWP的路损，单位dB。其中，BWP为带宽部分。UE根据参考信号q d测量的下行激活BWP的路损，单位dB。参考信号选择流程如下：
1.如果没有为UE提供PUSCH-PathlossReferenceRS高层配置参数或在UE被提供专用高层配置参数之前，UE使用获取MIB时用的SS/PBCH的参考信号；PathlossReference为路径损耗参考。
2.如果为UE配置了多组参考信号集，且每组参数信号集中通过ssb-Index关联SSB或csi-RS-Index关联CSI-RS(或同时)，具体使用哪组参考信号集需要根据PUSCH-PathlossReferenceRS-Id来确定，PUSCH-PathlossReferenceRS-Id确定的方法如下：
1)如果是通过RAR UL许可调度的PUSCH传输，UE使用与之对应的PRACH传输相同的参考信号资源索引q d；
2)如果配置了多组高层参数SRI-PUSCH-PowerControl，每组中都关联了一个PUSCH-PathlossReferenceRS-Id，并且如果DCI format 0_1包含一个SRI域，UE根据SRI-PUSCH-PowerControlId找到关联的q d，再根据q d从确定关联的SSB或CSI-RS参考信号索引ssb-Index或csi-RS-Index，进一步根据ssb-Index或csi-RS-Index确定小区参考 信号资源配置，确定的参考符号资源为服务小区c或由pathlossReferenceLinking指定小区的参考符号集；
3)如果是由DCI format 0_0调度的PUSCH传输，并且高层给UE激活BWP的第一个PUCCH资源配置了PUCCH-SpatialRelationInfo，则UE PUSCH使用第一个PUCCH资源中的RS资源q d；spatial relation info为空间关系信息。
4)如果是由DCI format 0_0调度的PUSCH传输，并且没有为UE PUCCH传输配置PUCCH-SpatialRelationInfo参数，或者通过不包含SRI域的DCI format 0_1调度，或没有给UE配置SRI-PUSCH-PowerControl IE，那么UE最终确定的参考信号资源索引q d等于0，对应当前服务小区或由pathlossReferenceLinking指示的服务小区上的参考信号资源；
5)对于免调度PUSCH传输，如果ConfiguredGrantConfig IE中包含有rrc-ConfiguredUplinkGrant，那么q d等于rrc-ConfiguredUplinkGrant中pathlossReferenceIndex对应的当前服务小区的参考信号资源或pathlossReferenceLinking指示的服务小区参考信号资源；
6)对于免调度PUSCH传输，如果ConfiguredGrantConfig IE中没包含rrc-ConfiguredUplinkGrant，那么UE根据激活时的DCI format 0_1的SRI域索引值映射的资源找出PathlossReferenceRS-Id配置，如果DCI中没有包含SRI域，那么UE最终确定的参考信号资源索引q d等于0，对应当前服务小区或由pathlossReferenceLinking指示的服务小区上的参考信号资源。
PL b,f,c(q d)＝referenceSignalPower–higher layer filtered RSRP，referenceSignalPower由高层参数配置，RSRP由q d对应的参考服务小区测量得到，高层滤波配置由参考服务小区的QuantityConfig配置。
如果UE没有配置周期CSI-RS接收，referenceSignalPower由 ss-PBCH-BlockPower提供，如果配置了周期CSI-RS接收，referenceSignalPower由ss-PBCH-BlockPower或powerControlOffsetSS提供的CSI-RS传输功率偏移量对应的SSB传输功率；如果没有配置powerControlOffsetSS，UE假设偏移量为0dB。
(6)Δ TF,b,f,c(i)：属于闭环参数，表示对不同的调制编码方案造成的接收功率变化进行补偿，通过高层参数deltaMCS控制是否使用该闭环参数。

1)如果UE有两个闭环进程，需要配置twoPUSCH-PC-AdjustmentStates，l∈{0,1}，如果UE不配置twoPUSCH-PC-AdjustmentStates，l＝0：
1>如果是由ConfiguredGrantConfig调度的PUSCH传输或重传，那么闭环进程号由powerControlLoopToUse指定；
2>如果为UE提供了SRI-PUSCH-PowerControl配置，那么UE通过DCI format 0_1的SRI找到关联的sri-PUSCH-ClosedLoopIndex；
3>如果是使用DCI format 0_0或者没有SRI域的DCI format 0_1调度的PUSCH传输，或者没有配置SRI-PUSCH-PowerControl，则,l＝0；

PUSCH的功率控制算法是开环工作点的设置和闭环功率控制算法两个部分。其中闭环功控反映在参数f(i)中，闭环功控功率调整量是测量值与目标值的差异确定的，目标值是针对不同用户不同的。
现有功控算法闭环目标值中没有考虑AMC的影响因素。因为过高的发送功率或者过低的发送功率并没有合适的MCS匹配其性能，因为AMC中MCS等级存在上限和下限。MCS等级的上限，导致并不是随着功率提升一定会带来性能提升，反而带来干扰增加的问题；MCS等级的下限，导致过低的功率并没有合适的MCS与其匹配，造成BLER增大的问题。
为了解决现有方案的不足，本公开实施例提出结合AMC的功率控制策略。当信道条件很差MCS等级较低，不再降低UE发射功率，以免性能继续下降。同理，当信道条件很好，UE不需要很大的发射功率时，可以降低UE发射功率，减少对其它用户性能的影响以及降低本区或邻区干扰。
事件或周期进行功率保护判定和具体功率调整操作，功率调整在发送TPC命令前产生。
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
