具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
在无线通信***中，基站传输和接收点(Transmission and Reception Point，TRP)/面板(PANEL)的应用主要为了改善小区边缘的覆盖，在服务区内提供更为均衡的服务质量，用不同的方式在多个TRP/PANEL间协作传输数据。从网络形态角度考虑，以大量的分布式接入点加基带集中处理的方式进行网络部署将更加有利于提供均衡的用户体验速率，并且显著的降低越区切换带来的时延和信令开销。利用多个TRP或面板之间的协作，从多个角度的多个波束进行信道的传输/接收，可以更好的克服各种遮挡/阻挡效应，保障链路连接的鲁棒性，适合超可靠低时延通信(Ultra Reliable Low Latency Communication，URLLC)业务提升传输质量和满足可靠性要求。
在R16研究阶段，基于下行多TRP/PANEL间的多点协作传输技术的应用，对物理下行共享信道(Physical Downlink Shared CHannel，PDSCH)进行了传输增强。由于数据传输包括上下行信道的调度反馈，因此在URLLC的研究中，只对下行数据信道增强不能保证业务性能。因此在R17的研究中，继续对物理下行控制信道(Physical Downlink Control Channel，PDCCH)以及物理上行链路控制信道(Physical Uplink Control CHannel，PUCCH)和物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)进行增强。
可以理解的是，R17的两种上行PUSCH时域重复传输的增强方式分别是R16引入的重复类型A传输方式和重复类型B传输方式。
进一步可以理解的是，R16的时隙级别的时隙聚合(Slot Aggregation)PUSCH传输不适用于某些时延要求很低可靠性要求很高的情况。图1为根据本公开实施例的一种PUSCH重复类型A的示例图。如图1所示，一个PUSCH在连续的K个时隙中传输，即K个传输时机，起始时隙中的第S个符号上开始传输，每个传输时机持续L个符号，同时S+L不同超过时隙边界。如图1所示，图1示出了传输时机K为2，起始时隙的开始符号S为0，每个传输时机持续的符号L为4。
进一步可以理解的是，为了降低时延提高可靠性，R16支持以迷你时隙(Mini-slot)为单位的PUSCH重复传输方案，且允许PUSCH传输跨时隙可以进一步降低时延。图2为根据本公开实施例的一种PUSCH重复类型B的示例图。如图2所示，在时域上，一个PUSCH在起始时隙中的第S个符号上开始传输，连续发送K个名义传输时机，每个名义传输时机都连续占用L个符号，传输S+L可以跨时隙边界。如图2所示，图2示出了传输时机K为2，起始时隙的开始符号S为0，每个传输时机持续的符号L为4。
进一步的，重复类型A传输方式和重复类型B传输方式的传输参数定义如表(1)所示：
Figure PCTCN2022111583-appb-000001
表(1)
可以理解的是，在现有的多TRP的传输中，PDSCH信道最多支持两个下行不同的TRP的协作传输，在时分复用技术(time-division multiplexing，TDM)方案中，类似上述Type A传输方式，是时隙级别的传输。不同的波束(波束方向指示为传输配置指示状态(transmission configuration indication state，TCI state))到不同重复的传输时机的映射方法，可以由高层信令采用半静态方式配置以确定每个传输块(Transport Block，TB)的具体传输映射方案。
进一步可以理解的是，TCI state和传输时机之间的映射关系主要有周期映射和连续映射这2种方案。当映射关系为周期映射时，两个TCI state依次循环映射到配置的多个传输时机上，例如当配置4次 传输时，TCI state映射的图样是#1#2#1#2。当映射关系为连续映射时，两个TCI state连续循环映射到配置的多个传输时机上，例如当配置4次传输时，TCI state映射的图样是#1#1#2#2，对于4次以上的传输，则重复该图样，如对于8次传输，则TCI state映射的图样是#1#1#2#2#1#1#2#2。
可以理解的是，在R17之前，上行传输均计算1个功率余量(Power Headroom，PH)并进行上报。R17对于上述两种基于M-TRP(多TRP)传输的上行PUSCH传输方案引入了per TRP的功率余量上报，即对于M-TRP传输，需要上报2个PHR。
进一步可以理解的是，R17不支持M-下行控制信息(downlink control information，DCI)下的调度传输。至于S-DCI调度传输，采用的上报方法是，当在时隙n中报告PHR MAC(Mediu Access Control)-CE(Control Element)时，对于配置有mTRP PUSCH重复传输的载波，第二功率余量报告(Power Headroom Reporting，PHR)值确定如下：
如果第一个PHR值是与给定TRP相关联的mTRP PUSCH重复传输对应的实际PHR，则与另一TRP相关联的第二个PHR值仅在时隙n中重复传输时才是实际PHR。否则，为虚拟PHR。
如果第一个PHR值是实际PHR，但不对应于mTRP PUSCH重复中的任一传输(对应于S-TRP PUSCH)，则第二个PHR值为虚拟PHR。
如果第一个PHR值为虚拟PHR，则第二个PHR值为虚拟PHR。
PHR反应了用户设备(User Equipment，UE)的可用功率，即功率余量，在上行传输的控制中，需要测量并上报给网络设备，UE只有在上行共享信道(Uplink Shared Channel，UL-SCH)被调度时才发送报告。UE根据协议规定触发PHR上报的触发条件。
这里与multi-TRP上行传输相关的主要是类型1功率余量报告，报告包括了功率余量和所在分量载波上的最大发射功率Pcmax，Pcmax是网络设备配置的。由于网络设备知道功率余量报告对应时刻的编码调制方式以及终端用于传输的资源大小，即可以确定调制编码方式(Modulation and Coding Scheme，MCS)和分配资源大小的有效组合。当没有实际的PUSCH传输时，UE也可以上报类型1功率余量。
当前的PHR测量机制包括实际PHR或者虚拟PHR。当有PUSCH传输时，UE上报实际PHR到网络设备，如果没有PUSCH传输，则UE根据预先定义的PUSCH格式计算一个PHR上报给网络设备，即虚拟PHR。网络设备将根据UE的功率差值信息，确定UE能够发送的带宽以及传输模式。
进一步的，PHR上报的内容包括：
各小区上可发送的最大功率；
各小区上UE发送上行控制信道(如PUCCH)后的功率余量；
各小区上UE发送上行数据信道(如PUSCH)后的功率余量；
各小区上UE发送上行探测信道(如探测参考信号(sounding reference signal，SRS))后的功率余量；
其中如果UE有真实的物理信道发送，则上报该物理信道真实发送后的功率余量。如果UE没有真实的物理信道发送，则上报该物理信道参考(或虚拟)发送后的功率余量。
进一步的，PHR的MAC CE的上报格式如表(2)所示：
Figure PCTCN2022111583-appb-000002
表(2)
其中，相关域的含义如下：
Ci:如果1个辅小区(Secondary Cell，SCell)通过无线资源控制(Radio Resource Control，RRC)消息配置有SCellIndex，那么该域指示是否上报了配置有SCellIndex i的SCell的PH域。Ci域设置成“1”指示上报了配置有SCellIndex i的SCell的PH域。Ci域设置成“0”指示没有上报配置有SCellIndex i的SCell的PH域。
R:预留比特，设置成"0"。
V:该域指示上报的PH值是基于真实传输还是参考格式。对于Type 1PH,V＝0指示基于PUSCH上的真实传输，而V＝1指示基于PUSCH的参考格式。对于Type 2PH,V＝0指示基于PUCCH上的真实传输,而V＝1指示基于PUCCH的参考格式。对于Type 3PH,V＝0指示基于SRS上的真实传输,而V＝1指示基于SRS的参考格式。此外，对于Type 1,Type 2and Type 3PH,V＝0指示上报格式中包含了某小区对应的P CMAX,c域,而V＝1指示上报格式中没有包含某小区对应的P CMAX,c域。
PH：该域指示功率余量的等级。
P:该域指示是否当前MAC实体采用了功率回退机制。在没有功率回退时，如果某小区对应的P CMAX,c域有不同的取值，MAC实体设置P＝1。
P CMAX,c:如果该域存在，则指示用于计算对应的PH域值的P CMAX,c的数值，即UE计算的在该小区可发送的最大功率。
进一步的，PH的类型包括：
Type 1PH：PH type1,c(i)＝P CMAX,c–P PUSCH,c(i)
Type 2PH：PH type2,c(i)＝P CMAX,c–P PUSCH,c(i)–P PUCCH,c(i)
Type 3PH：PH type3,c(i)＝P CMAX,c–P SRS,c(i)
其中，“i”为某子帧“i”。
P PUSCH,c(i)：为UE根据计算获得的上行数据信道(PUSCH)的发射功率。当UE有实际信号发送时，该值为根据实际发送的信道功率确定。当UE没有实际信号发送时，该值为根据参考的(或虚拟的)信道功率确定。
P PUCCH,c(i)：为UE根据计算获得的上行控制信道(PUCCH)的发射功率。当UE有实际信号发送时，该值为根据实际发送的信道功率确定。当UE没有实际信号发送时，该值为根据参考的(或虚拟的)信道功率确定。
P SRS,c(i)：为UE根据计算获得的上行探测参考信道(SRS)的发射功率。当UE有实际信号发送时，该值为根据实际发送的信道功率确定。当UE没有实际信号发送时，该值为根据参考的(或虚拟的)信道功率确定。
可以理解的是，UE可以被配置为单载波传输，或多载波传输，其中对应多载波传输配置的情况如下：
载波聚合(Carrier Aggregation，CA)小区激活与去激活状态：UE配置了CA时，包括多个小区：1个主小区(Primary Cell，PCell)、1个或多个SCell；当前CA配置中1个下行载波会有1个对应的上行载波。
双连接(Dual Connectivity，DC)：UE配置了CA时，包括多个小区组：主小区组(Master Cell Group，MCG)、辅小区组(Secondary Cell Group，SCG)；其中MCG包括1个PCell和0个或多个SCell，SCG包括1个PSCell和0个或多个SCell。
补充上行载波(Supplement Uplink carrier，SUL carrier)：在5G***中，对于1个下行载波可以配置2个上行载波，其中1个为补充上行载波，该补充上行载波可以配置给PCell或SCell。
可以理解的是，目前通信***的瓶颈仍然在上行传输的速率及覆盖等，因此对于R18标准的***增强方向，主要是考虑在Multi-TRP场景下，利用多panel进行上行同时传输来提高上行速率，并进一步提高传输的可靠性。传输可以基于一个PDCCH信道承载的一个下行控制信息(downlink control information，DCI)进行调度，也可以考虑基于不同PDCCH承载的不同DCI分别调度。PUSCH的传输可以为基于单个PDCCH即S-DCI(单DCI)调度的多PANEL/TRP传输，可以使用空分复用(Space Division Multiplexing，SDM)/频分多路复用(Frequency Division Multiplexing，FDM)复用方式，如图3所示，PUSCH的传输也可以为基于不同PDCCH即M-DCI(多DCI)调度的多PANEL/TRP传输，也可以使用SDM/FDM复用方式，如图4所示。
进一步可以理解的是，对于M-DCI调度，在不同的天线面板上通过各自独立的PDCCH调度信息调度各自的PUSCH传输，如图4所示，分别表示为PUSCH1和PUSCH2。对应M-DCI调度的不同PUSCH，可能的资源分配方式如图5所示，其中，时域资源完全重叠而频域资源不限定；或者，时域资源部分重叠而频域资源不限定；或者，时域资源完全不重叠而频域资源不限定。
进一步的，在R18上行多进多出(Multiple-Input Multiple-Output，MIMO)增强中，考虑通过多panel实现面向多TRP的上行同时传输，进一步提高上行的***传输吞吐率和传输可靠性，为了支持基于多panel的上行同时传输，现有PHR上报机制需要增强，以提供基于M-DCI调度下物理上行信道传输的PHR上报方案。
为此，本公开提出了一种基于多下行控制信息M-DCI的功率余量PHR上报方法及装置，使得上行的***的传输吞吐率和传输可靠性提高，同时提高网络侧每一个面板的上行传输调度的准确性。
下面结合附图对本申请所提供的基于多下行控制信息M-DCI的功率余量PHR上报方法及装置进行详细地介绍。
图6示出了根据本公开实施例的一种基于多下行控制信息M-DCI的功率余量PHR上报方法的流程示意图。如图6所示，该方法可由用户设备UE执行，且可以包括以下步骤：
S601，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定待上报PHR数量M。
在一些实施例中，M为UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量中的较小者。
在一示例中，当用户设备UE只支持上报一个PHR时，网络设备通常地可以配置并触发最多一个PHR上报。
在另一示例中，当用户设备UE支持上报多个PHR时，网络设备通常地可以配置并触发一个或多个PHR上报。
S602，UE将N个物理下行控制信道PDCCH调度的N个物理上行信道中的M个物理上行信道的各自PHR上报给网络设备，N大于等于2，M小于等于N。
在M-DCI调度下，通过多个PDCCH来调度多个物理上行信道，其中每个PDCCH调度1个物理上行信道。
UE根据确定出的待上报PHR数量M，将多个物理上行信道中的M个物理上行信道的各自PHR上报给网络设备。
本公开实施例的基于M-DCI的PHR上报方法及装置，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定待上报PHR数量M；将N个物理下行控制信道PDCCH调度的N个物理上行信道中的M个物理上行信道的各自PHR上报给网络设备，由此，根据本实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法及装置，可以在M-DCI调度下上报多个PHR，支持基于多面板的上行同时传输，可以提高上行的***的传输吞吐率和传输可靠性，可以提高网络侧每一个面板的上行传输调度的准确性。
图7示出了根据本公开实施例的一种基于M-DCI的PHR上报方法的流程示意图。如图7所示，该方法可由用户设备UE执行，且可以包括以下步骤：
S701，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定待上报PHR数量M。
关于S701的具体实施细节，可以参考上述步骤S601的细节，在此不再赘述。
S702，UE根据预配置规则确定N个物理上行信道的各自PHR的上报优先级。
在M-DCI调度下，对于多个PDCCH调度的多个上行信道PUSCH/PUCCH时，UE可以根据预配置规则，考虑不同上行信道PUSCH/PUCCH的各自PHR的上报优先级。其中，PUSCH可以为支持STxMP的PUSCH。
在本实施例中，可以根据N个物理上行信道的资源分配情况确定对应的预配置规则。该N个物理上行信道的资源分配情况可以为于N个物理上行信道的时域资源完全重合，该N个物理上行信道的资源分配情况也可以为N个物理上行信道的时域资源部分重合或完全不重合。
S703，UE根据上报优先级从所述N个物理上行信道中确定M个物理上行信道。
UE在确定在M-DCI调度下的N个物理上行信道的各自PHR的上报优先级后，可以基于上报优先级从N个物理上行信道中确定需要针对其上报PHR的M个物理上行信道。
S704，UE将M个物理上行信道的各自PHR上报给网络设备。
UE将确定出的M个物理上行信道的各自PHR上报给网络设备。
根据本公开实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定待上报PHR数量M，根据预配置规则确定N个PDCCH调度的N个物理上行信道的各自PHR的上报优先级，基于上报优先级将M 个物理上行信道的各自PHR上报给网络设备，由此，根据本实施例的基于M-DCI的PHR上报方法，根据预配置规则确定上报优先级，并基于上报优先级上报PHR，可以在M-DCI调度下，支持基于多面板的上行同时传输，可以提高上行的***的传输吞吐率和传输可靠性，可以提高网络侧每一个面板的上行传输调度的准确性。
本公开实施例还提供了一种基于M-DCI的功率余量PHR上报方法，该方法可由UE执行，且可以包括图7中所示的步骤S701-S704。
在一些实施例中，当N个物理上行信道的时域资源完全重合时，预配置规则为PHR的上报优先级取决于以下中的至少一个：
物理上行信道关联的控制资源集(control-resource set，CORESET)池索引(Pool Index)；
物理上行信道对应的PDCCH的发送时间；
计算得出的待上报PHR的值；
物理上行信道对应的传输控制信息所关联的终端能力索引；
物理上行信道关联的天线面板标识。
在一示例中，UE可以基于不同物理上行信道，例如PUSCH、PUCCH，关联的CORESET Pool Index ID大小确定PHR的上报优先级。例如，CORESET Pool Index ID越小，CORESET Pool Index ID关联的物理上行信道上报的PHR的上报优先级越高。在另一示例中，CORESET Pool Index ID越大，CORESET Pool Index ID关联的物理上行信道上报的PHR的上报优先级越高。
在另一示例中，UE可以PDCCH的发送时间确定PHR的上报优先级，例如，PDCCH的发送时间越早，该PDCCH对应的物理上行信道上报的PHR的上报优先级越高。
在本实施例中，UE可以计算得出待上报PHR的值。从而，用户设备UE可以根据该待上报PHR的值确定为PHR的上报优先级。例如，UE可以设置待上报PHR的值越小，该待上报PHR的上报优先级越高。在另一示例中，UE可以设置上报PHR的值小于预设阈值时，该待上报PHR具有高上报优先级越。
在一示例中，UE可以基于物理上行信道对应的传输控制信息所关联的终端能力索引UE capability value index的取值确定PHR的上报优先级。例如，UE可以设置UE capability value index的取值越小，该UE capability value index对应的物理上行信道上报的PHR的上报优先级越高。在另一示例中，UE可以设置UE capability value index的取值越大，该UE capability value index对应的物理上行信道上报的PHR的上报优先级越高。
在另一示例中，UE可以基于天线面板标识对应的panel ID的取值确定PHR的上报优先级。例如，UE可以设置panel ID的取值越小，该panel ID对应的物理上行信道上报的PHR的上报优先级越高。又如，UE还可以设置panel ID的取值越大，该panel ID对应的物理上行信道上报的PHR的上报优先级越高。
在一些实施例中，UE在计算待上报PHR的值时，UE可以基于相应的天线面板的最大发射功率或UE的最大发射功率计算得出待上报PHR的值。
在一示例中，UE可以基于相应的天线面板的最大发射功率Pcmax计算对应的PUSCH/PUCCH传输时机的待上报PHR的值。
在另一示例中，UE可以基于UE的最大发射功率Pcmax计算得出对应的PUSCH/PUCCH传输时机的待上报PHR的值。
以上示例虽然是根据上述所列中的一项来确定PHR的上报优先级。但应理解的是，可以根据上述所列的多项来确定PHR的上报优先级。例如，在另一示例中，UE可以基于PDCCH的发送时间以及物理上行信道关联的CORESET Pool Index ID大小确定PHR的上报优先级。例如，当PDCCH的发送时间相同，进一步根据物理上行信道关联的CORESET Pool Index ID大小确定PHR的上报优先级，如，CORESET Pool Index ID越小，该PDCCH对应的物理上行信道上报的PHR的上报优先级越高。
根据本公开实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，用户设备UE根据预配置规则确定在M-DCI调度下的N个物理上行信道的一个或多个PHR的各自上报优先级，基于上报优先级将M个PHR上报给网络设备，由此，根据本实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，根据预配置规则确定上报优先级，并基于上报优先级上报PHR，可以在M-DCI调度下，支持基于多面板的上行同时传输，可以提高上行的***的传输吞吐率和传输可靠性，可以提高网络侧每一个面板的上行传输调度的准确性。
本公开实施例还提供了一种基于多下行控制信息M-DCI的功率余量PHR上报方法，该方法可由UE执行，且可以包括图7中所示的步骤S701-S704。
在一些实施例中，当N个物理上行信道的时域资源部分重合或完全不重合时，预配置规则为PHR的上报优先级取决于以下中的至少一个：
物理上行信道的发送时间；
物理上行信道关联的控制资源集CORESET池索引；
物理上行信道对应的PDCCH的发送时间；
计算得出的待上报PHR的值；
物理上行信道对应的传输控制信息所关联的终端能力索引；
物理上行信道关联的天线面板标识。
在一示例中，UE可以在PUSCH/PUCCH的发送时间确定PHR的上报优先级。例如，PUSCH/PUCCH的发送时间越早，该PUSCH/PUCCH对应的物理上行信道上报的PHR的上报优先级越高。
在另一示例中，UE可以基于不同物理上行信道，例如PUSCH、PUCCH，关联的CORESET Pool Index ID大小确定PHR的上报优先级。例如，CORESET Pool Index ID越小，CORESET Pool Index ID关联的物理上行信道上报的PHR的上报优先级越高。在另一示例中，CORESET Pool Index ID越大，CORESET Pool Index ID关联的物理上行信道上报的PHR的上报优先级越高。
在本实施例中，UE可以在PDCCH的发送时间确定PHR的上报优先级。例如，PDCCH的发送时间越早，该PDCCH对应的物理上行信道上报的PHR的上报优先级越高。
在本实施例中，UE可以计算得出待上报PHR的值。从而，用户设备UE可以根据该待上报PHR的值确定为PHR的上报优先级。例如，UE可以设置待上报PHR的值越小，该待上报PHR的上报优先级越高。在另一示例中，UE可以设置上报PHR的值小于预设阈值时，该待上报PHR具有高上报优先级越。
在一示例中，UE可以基于物理上行信道对应的传输控制信息所关联的终端能力索引UE capability value index的取值确定PHR的上报优先级。例如，用户设备UE可以设置UE capability value index的取值越小，该UE capability value index对应的物理上行信道上报的PHR的上报优先级越高。在另一示例中，UE可以设置UE capability value index的取值越大，该UE capability value index对应的物理上行信道上报的PHR的上报优先级越高。
在另一示例中，UE可以基于天线面板标识对应的panel ID的取值确定PHR的上报优先级。例如，用户设备UE可以设置panel ID的取值越小，该panel ID对应的物理上行信道上报的PHR的上报优先级越高。又如，UE还可以设置panel ID的取值越大，该panel ID对应的物理上行信道上报的PHR的上报优先级越高。
在一些实施例中，UE在计算待上报PHR的值时，UE可以基于相应的天线面板的最大发射功率或UE的最大发射功率计算得出待上报PHR的值。
在一示例中，UE可以基于相应的天线面板的最大发射功率Pcmax计算对应的PUSCH/PUCCH传输时机的待上报PHR的值。
在另一示例中，UE可以基于UE的最大发射功率Pcmax计算得出对应的PUSCH/PUCCH传输时机的待上报PHR的值。
以上示例虽然是根据上述所列中的一项来确定PHR的上报优先级。但应理解的是，可以根据上述所列的多项来确定PHR的上报优先级。例如，在另一示例中，UE可以基于PDCCH的发送时间以及物理上行信道关联的CORESET Pool Index ID大小确定PHR的上报优先级。例如，当PDCCH的发送时间相同，进一步根据物理上行信道关联的CORESET Pool Index ID大小确定PHR的上报优先级，如，CORESET Pool Index ID越小，该PDCCH对应的物理上行信道上报的PHR的上报优先级越高。
根据本公开实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，用户设备UE根据预配置规则确定在M-DCI调度下的N个物理上行信道的一个或多个PHR的各自上报优先级，基于上报优先级将M个PHR上报给网络设备，由此，根据本实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，根据预配置规则确定上报优先级，并基于上报优先级上报PHR，可以在M-DCI调度下，支持基于多面板的上行同时传输，可以提高上行的***的传输吞吐率和传输可靠性，可以提高网络侧每一个面板的上行传输调度的准确性。
图8示出了根据本公开实施例的一种基于多下行控制信息M-DCI的功率余量PHR上报方法的流程示意图。如图8所示，该方法可由用户设备UE执行，且可以包括以下步骤：
S801，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定待上报PHR数量M。
S802，UE根据预配置规则确定N个物理上行信道的各自PHR的上报优先级。
S803，UE根据上报优先级从所述N个物理上行信道中确定M个物理上行信道。
S804，UE将M个物理上行信道的各自PHR上报给网络设备。
关于上述步骤S801-S804的描述和具体细节，可以参考上述步骤S701-S704的相关描述与细节。
在一示例中，UE在根据预配置规则确定在M-DCI调度下的N个物理上行信道的各自PHR的上报优先级后，可以由按照各自PHR的上报优先级顺序排序，将排序在前的M个物理上行信道的各自PHR进行上报。
在一些实施例中，上述步骤S803可以包括以下步骤：
S8031：根据N个物理上行信道按照各自PHR的上报优先级排序，确定排序在前的M个物理上行信道。
例如，在M-DCI调度下，对于4个PDCCH调度的4个上行信道PUSCH/PUCCH，当用户设备UE仅支持上报两个PHR时，网络设备配置并触发最多2个PHR上报。此时，UE确定待上报PHR数量为2，UE可以按照4个物理上行信道的各自PHR的上报优先级排序，将排序在前(即优先级较高)的两个物理上行信道的各自PHR上报给网络设备。
在一些实施例中，在上报M个物理上行信道的各自PHR时，可以按照该M个物理上行信道的各自PHR的上报优先级的顺序，按照优先级从高到低的方式，依次上报M个物理上行信道的各自PHR。即，若上报2个物理上行信道的各自PHR，其中第一物理上行信道的PHR的上报优先级高于第二物理上行信道的PHR的上报优先级，则先上报第一物理上行信道的PHR，然后上报第二物理上行信道的PHR。
根据本公开实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，用户设备UE根据预配置规则确定在M-DCI调度下的N个物理上行信道的一个或多个PHR的各自上报优先级，基于上报优先级将M个PHR上报给网络设备，由此，根据本实施例的基于多下行控制信息M-DCI的功率余量PHR上报方法，根据预配置规则确定上报优先级，并基于上报优先级上报PHR，可以在M-DCI调度下，支持基于多面板的上行同时传输，可以提高上行的***的传输吞吐率和传输可靠性，可以提高网络侧每一个面板的上行传输调度的准确性。
图9示出了根据本公开实施例的一种基于多下行控制信息M-DCI的功率余量PHR上报方法的流程示意图。如图9所示，该方法可由网络设备执行，且可以包括以下步骤：
S901，网络设备接收UE上报的M个物理上行信道的各自PHR；
其中，UE根据UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量确定M，M个物理上行信道为N个物理下行控制信道PDCCH调度的N个物理上行信道中的物理上行信道，M小于等于N，N大于等于2。
在一些实施例中，M为UE支持的第一最大PHR上报数量和网络设备配置的第二最大PHR上报数量中的较小者。
在一些实施例中，UE根据预设配置规则确定确定N个物理上行信道的各自PHR的上报优先级，并根据上报优先级从N个物理上行信道中确定M个物理上行信道。
在一示例中，当N个物理上行信道的时域资源完全重合时，预配置规则为PHR的上报优先级取决于以下中的至少一个：
物理上行信道关联的控制资源集CORESET池索引；
物理上行信道对应的PDCCH的发送时间；

物理上行信道对应的PDCCH的发送时间；
计算得出的待上报PHR的值；
物理上行信道对应的传输控制信息所关联的终端能力索引；
物理上行信道关联的天线面板标识。
在一些实施例中，对于任意两个物理上行信道，
当第一物理上行信道关联的CORESET池索引小于第二物理上行信道关联的CORESET池索引时，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级；
当第一物理上行信道对应的PDCCH发送时间比第二物理上行信道对应的PDCCH发送时间早时，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级；
当第一物理上行信道的待上报PHR的值小于第二物理上行信道的待上报的PHR的值时，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级；
当第一物理上行信道对应的传输控制信息所关联的终端能力索引小于第二物理上行信道对应的传输控制信息所关联的终端能力索引，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级；
当第一物理上行信道关联的天线面板标识小于第二物理上行信道关联的天线面板标识时，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级。
在一些实施例中，对于任意两个物理上行信道，当第一物理上行信道的发送时间早于第二物理上行信道的发送时间时，第一物理上行信道的PHR的上报优先级高于与第二物理上行信道的PHR的上报优先级。
在一些实施例中，基于相应的天线面板的最大发射功率或UE的最大发射功率计算得出待上报PHR的值。
