附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图是本申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
应理解，本申请实施例的技术方案可以应用于本申请提供的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、5G通信系统(例如新空口(New Radio，NR))，所述5G移动通信系统包括非独立组网(non-standalone，NSA)的5G移动通信系统和/或独立组网(standalone，SA)的5G移动通信系统。本申请提供的技术方案还可以应用于多种通信技术融合的通信系统(例如LTE技术和NR技术融合的通信系统)、或者适用于未来新的各种通信系统，例如6G通信系统、7G通信系统等，本申请实施例对此不作限定。本申请实施例的技术方案也适用于不同的网络架构，包括但不限于中继网络架构、双连接架构、车辆到任何物体的通信(Vehicle-to-Everything)架构等。
本申请实施例涉及的网络设备，可以是基站(Base Station，BS)，也可称为基站设备，是一种部署在无线接入网用以提供无线通信功能的装置。例如在2G网络中提供基站功能的设备包括基地无线收发站(Base Transceiver Station，BTS)和基站控制器(Base Station Controller，BSC)，3G网络中提供基站功能的设备包括节点B(NodeB)和无线网络控制器(Radio Network Controller，RNC)，在4G网络中提供基站功能的设备包括演进的节点B(evolved NodeB，eNB)，在无线局域网络(Wireless Local Area Networks，WLAN)中，提供基站功能的设备为接入点(Access Point，AP)，5G新无线(New Radio，NR)中的提供基站功能的设备包括继续演进的节点B(gNB)，以及未来新的通信系统中提供基站功能的设备等。
本申请实施例涉及终端设备包括无线通信功能的设备，该终端设备可以是手机(mobile phone)、平板电脑(pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端设备、增强现实(Augmented Reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、智能家庭(smart home)中的无线终端等。终端设备也可以是具有无线通信功能的手持设备、车载设备、可穿戴设备、计算机设备或连接到无线调制解调器的其他处理设备、未来5G网络中的终端设备或者未来演进的公 用陆地移动通信网络(Public Land Mobile Network，简称PLMN)中的终端设备等。在不同的网络中终端设备可以叫做不同的名称，例如：用户设备、接入终端、用户单元、用户站、移动站、移动台(Mobile Station，MS)、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置、蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、5G网络或未来演进网络中的终端设备等，本申请实施例对此并不限定。
请参阅图1，图1是本申请实施例提出的一种无线通信系统的示意图。如图1所示，该无线通信系统可以包括网络设备和终端设备。网络设备可以与终端设备通过无线通信进行通信。在网络设备与终端设备通信的过程中，网络设备可以给终端设备配置适当的信号状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)资源或者同步信号和PBCH块(Synchronization Signal and PBCH block，SSB)，然后终端设备对CSI-RS或者SSB进行测量并计算出所需要的信号状态信息(Channel State Information，CSI)，并上报该CSI，网络设备会根据上报的内容进行调度的调整以及波束管理相关的工作。
可以理解的是，图1中所示的网络设备和终端设备的形态和数量仅用于举例，并不构成对本申请实施例的限定。
目前一个CSI报告配置会关联一个CSI资源集或者2个CSI资源集。当CSI资源集被配置为非周期的TRS资源集时，CSI报告配置中所包含的报告量(reportQuantity)被设置为’none’；而对于周期性的TRS资源集，目前协议不支持配置关联一个CSI报告配置。并且目前NR R18协议中支持通过基于TRS的测量以及终端设备上报时域信道属性。但对于实现此功能，目前并无具体方案。
为了解决上述问题，本申请提出了一种CSI上报方法，网络设备向终端设备发送网络配置信息，该网络配置信息指示终端设备上报携带时域信道属性信息的CSI报告，终端设备接收到该网络配置信息后上报包括时域信道属性信息的CSI报告，从而使得终端设备能够支持上报时域信道属性的上报。
为了使本技术领域的人员更好地理解本申请方案，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、完整地描述，显然，所描述的实施例仅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在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图2，图2为本申请实施例提供的一种CSI上报方法流程示意图，应用于如图1所示的无线通信系统。如图2所示，该方法包括如下步骤。
S210、网络设备向终端设备发送网络配置信息，所述网络配置信息包括信道状态信息CSI报告配置信息，所述CSI报告配置信息包括第一信息，所述第一信息用于指示终端设备上报的目标CSI报告包括时域信道属性信息。
其中，终端设备进行CSI测量和CSI上报之前，网络设备可以向终端设备发送网络配置信息，终端设备可以根据网络配置信息进行CSI测量和CSI上报。
在本申请实施例中，为了使终端设备支持时域信道属性的上报，网络设备可以向终端设备发送网络配置信息，该网络配置信息可以为无线资源控制(radio resource control，RRC)高层配置的信息。具体为该网络配置信息可以包括CSI报告配置(CSI-ReportConfig)信息，该CSI报告配置信息中包含了CSI上报的相关配置参数和/或第一信息，该第一信息可以指示终端设备在此次上报的CSI报告中携带时域信道属性信息，以使网络设备能够根据时域信道属性信息提高网络设备所应用的CSI与当前时刻的信道的匹配度，进而提高数据传输性能。例如，CSI报告配置信息中包括第一信息，根据该第一信息，终端设备可以知道此次上报的目标CSI报告中需要携带时域属性信息。
其中，所述第一信息可以显示或隐式的指示终端设备上报时域信道属性信息。示例的，上述第一信息可以采用1个比特来显示指示，当然还可以为其他的比特位数，例如，网络设备配置终端设备需要上报时域信道属性信息，该第一信息可取值1；网络设备未配置终端设备需要上报时域信道属性信息，该第一信息可取值为0。
示例的，上述第一信息可以为reportQuantity(报告数量)，终端设备根据reportQuantity的具体内容隐式获知是否需要上报时域信道属性信息。例如，若reportQuantity不配置为“none”，且此CSI报告所关联的CSI资源是TRS，则终端设备需要上报时域信道属性信息；若reportQuantity配置为“none”，则终端设备可不需要上报时域信道属性信息。
可选的，所述时域信道属性信息包括以下至少一项：多普勒频移、多普勒扩展、时延扩展、平均时延、多普勒频移差、多普勒扩展差、时延扩展差、平均时延差、多普勒频移变化率、多普勒扩展变化率、时延扩展变化率、平均时延变化率。
具体地，信道扩展是无线信道的重要特性，上述多普勒频移、多普勒扩展、时延扩展、平均时延是信道扩展中的相关参数指标，其均会影响网络设备与终端设备之间的无线通信质量。因此本申请将上述时域信道属性信息上报给网络设备，以使网络设备能够选择更佳合适的波束，提高系统性能。
在本申请实施例中，网络设备指示终端设备上报时域信道属性信息，进而使得网络设备可以根据其上报的时域信道属性信息更加全面的获取当前的信道条件，提高网络设备所应用的CSI与当前时刻的信道的匹配度，进而提高数据传输性能。
可选的，所述CSI报告配置信息还包括reportQuantity，所述reportQuantity不配置为none。
在本申请实施例中，由于网络设备需要终端设备上报时域信道属性信息，因此网络设备可将CSI报告配置中的reportQuantity不配置为none，并且指明终端需要上报测量内容。示例的，终端设备需要上报的测量内容还可以包括用于给网络设备提供调度方面的辅助信息(如(信道质量指示(Channel Quality Indicator，CQI)、预编码指示(Precoding Matrix Indicator，PMI)、秩指示(Rand Indication，RI)等)，也可以包括用于给网络设备提供波束(beam)管理的信息(如CSI参考信号接收功(CSI-Reference Signal Receiving Power，cri-RSRP)、SSB-Index-RSRP等)，本申请实施例对此不做限定。
在一种可能的示例中，所述网络配置信息还包括CSI资源配置信息，所述CSI资源配置信息包括周期性的跟踪参考信号TRS资源集或非周期性的TRS资源集。
其中，网络设备配置CSI报告配置，会配置与该CSI报告配置对应的一个或多个CSI测量资源集，每个CSI测量资源集可包括一个或多个CSI测量资源，每个CSI测量资源集可包括信道测量资源集和/或干扰测量资源集。示例的，所述CSI资源配置信息中还包括一个或多个CSI资源集。
其中，TRS可以用于终端设备进行时频跟踪和/或多普勒扩展的估计等。本申请中的终端设备支持上报时域信道属性信息，也支持基于TRS的测量。因此网络设备配置CSI报告配置，可配置与该CSI报告配置关联的TRS资源集，以供终端设备进行TRS测量和CSI上报，即网络设备配置的CSI-RS资源需为TRS资源。其中该TRS资源集可以是周期性的TRS资源集，可以使得终端设备周期性的跟踪时偏、频偏和多普勒扩展等；该TRS资源集也可以是非周期性的TRS资源集，可以让网络设备按需决定是否发送TRS，并告知终端设备此TRS的存在和配置。
S220、终端设备接收所述网络配置信息，并基于所述网络配置信息，上报所述目标CSI报告。
其中，网络设备配置得到CSI报告配置信息和对应的CSI资源配置信息后，可以通过高层信令或物理层信令发送给终端设备。此时，终端设备可以获取到来自网络设备的CSI报告配置信息和CSI资源配置信息。并根据CSI报告配置信息和TRS资源集生成目标CSI报告。
进一步地，终端设备生成目标CSI报告的过程中，可以根据网络设备的指示，从TRS资源集中选择一个或多个TRS测量资源，根据选择的一个或多个TRS测量资源生成目标CSI报告，该目标CSI报告中的CSI信息包括时域信道属性信息。
示例的，若网络设备指示了终端设备需要上报其他测量内容，终端设备生成目标CSI报告的过程中，也可以从一个或多个CSI资源集中选择N个CSI测量资源，根据选择的N个CSI测量资源生成目标CSI报告，该目标CSI报告中的CSI信息可包括时域信道属性信息、CSI相关信息以及L1-RSRP相关的信息。其中，N为大于0且小于或等于M的整数，M为上述CSI资源集中的CSI测量资源的数量。
在当前协议中，对于CSI报告，协议具体规定了其优先级确定方式。CSI上报与其优先级值相关联，终端设备可根据优先级计算公式分别计算其要上报的每个CSI报告的优先级值，进而根据优先级值的大小依次处理CSI的上报。
可选的，所述目标CSI报告的CSI上报系数与第一CSI报告的CSI上报系数相同，所述CSI上报系数为CSI报告的优先级计算公式中用于表征CSI报告是否承载层一参考信号接收功率L1-RSRP或层一信号与干扰加噪声比L1-SINR的系数，所述第一CSI报告携带CSI获取信息。
其中，资源受限时，终端设备可根据CSI报告的优先级值来确定CSI报告的上报顺序，其优先级值代表的优先级越高，终端设备会越优先处理。即传输的时频资源受限，终端设备可以放弃(drop)优先级较低的CSI上报；也可以是计算资源CPU受限时，终端设备可以不更新低优先级的CSI，即不进行低优先级CSI的计算。
在本申请实施例中，终端设备可以根据CSI报告中所包含的测量内容来计算该CSI报告的优先级值，并根据CSI的优先级值进行上报。其中终端设备可根据预设优先级公式确定目标CSI报告的优先级值，该目标CSI报告的优先级值Pri iCSI(y,k,c,s)具体可以表示为：
Pri iCSI(y,k,c,s)＝2*N cells*M s*y+N cells*M s*k+M s*c+s。
其中，具体地，y＝0可用于物理上行共享信道PUSCH上承载的非周期CSI报告，y＝1可用于PUSCH上承载的半持续CSI报告，y＝2可用于物理上行控制信道PUCCH上承载的半持续CSI报告，y＝3可用于PUCCH上承载的周期CSI报告。所述N cells具体可以为高层参数maxNrofServingCells的值，所述s具体可以为reportConfigID的值，所述M s具体可以为高层参数maxNrofCSIReportConfigurations的值。k＝0可用于承载L1-RSRP或L1-SINR的CSI报告，k＝1可用于承载非L1-RSRP或L1-SINR的CSI报告。如果一个CSI报告A关联的Pri iCSI(y,k,c,s)取值小于一个CSI报告B关联的Pri iCSI(y,k,c,s)的取值，则CSI报告A的优先级高于CSI报告B。
其中，L1-RSRP表示物理层的参考信号接收功率(Reference Signal Receiving Power，RSRP)；L1-SINR表示物理层的信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)。
在当前协议中，CSI报告要么承载L1-RSRP或L1-SINR，要么承载CSI获取信息，如RI、和/或者PMI、和/或者CQI等，故在当前协议中，仅是简单地分为两大类：承载L1-RSRP或L1-SINR的CSI报告，承载非L1-RSRP或L1-SINR的CSI报告。在本申请实施例中，由于目标CSI报告包含时域信道属性信息，其不同于L1-RSRP，也不同于L1-SINR，也不同于CSI获取信息，因此终端设备可将目标CSI报告的CSI上报系数k的取值设置成与携带CSI获取信息或者承载L1-RSRP或L1-SINR的CSI报告的CSI上报系数k相同或者不同。进而再根据CSI的类型，小区索引，CSI-ReporConfigId计算目标CSI报告的优先级。具体地，示例性的，目标CSI报告包含时域信道属性信息，因此终端设备可将目标CSI报告的CSI上报系数k的取值设置为k＝0，也可以设置为k＝1，也可以设置为k＝2，有可以设置为k＝1.5，也可以设置为k＝0.5，也可以设置为k＝-0.5，也可以设置为k＝-1。
需要说明的是，5G标准中规定的服务小区最大数量的名称为maxNrofServingCells、CSI报告的配置索引的名称为reportConfigID、CSI报告的配置的最大数量的名称为maxNrofCSIReportConfigurations，但其他标准中规定相同含义的名称也同样适用于本申请，即本申请并不限制这些参数的名称。
需要是说明的是，关于终端设备使用CSI报告的优先级等级与网络设备进行交互的具体方式，可以参照已有技术，本发明实施例对此不做限制。
可选的，所述目标CSI报告占用的CSI处理单元CPU的数目为以下任一项：1、4、0。
其中，终端设备进行CSI测量的过程中需要占用资源，CSI处理单元(CSI processing unit，CPU)表示的是终端设备处理CSI的能力。CSI报告占用的CPU数目的不同表示终端设备对该CSI报告的处理能力不同，其占用的CPU数目越多，代表获得此CSI报告需要消耗越多的处理能力。终端设备预先会指示其的处理能力和/或其能同时计算的CSI数目N CPU。如果一个终端设备能同时计算N CPU个CSI，则表示该终端设备有N CPU个CPU来处理CSI报告。目前协议中规定了每个CSI报告占用的CPU的数目，以及占用CPU的时间。
在本申请实施例中，终端设备进行CSI测量和生成目标CSI报告的过程中，可以占用1个CPU、4个CPU或0个CPU，本申请实施例对此不做限定。示例的，终端设备可以根据其能同时计算的CSI数目N CPU和/或当前未被占用的CPU数目来选择目标CSI报告占用的CPU数目。示例的，终端设备也可以从1、4、0中随机选择目标CSI报告占用的CPU数目。
可选的，所述目标CSI报告的CSI处理时间需求与第二CSI报告的CSI处理时间需求相同，所述第二CSI报告携带L1-RSRP或L1-SINR。
在本申请实施例中，在终端设备向网络设备上报的CSI信息为时域信道属性信息时，可以将目标CSI报告的CSI处理时间设置为与携带L1-RSRP或L1-SINR的CSI报告的CSI处理时间相同。
S230、网络设备接收所述目标CSI报告。
其中，网络设备接收到终端设备发送的目标CSI报告后，可根据其携带的时域信道属性信息更加全面的获取当前的信道条件，提高网络设备所应用的CSI与当前时刻的信道的匹配度，进而提高数据传输性能。
可以看出，本申请提出了一种CSI上报方法，终端设备接收网络设备发送的网络配置信息，该网络配置信息包括信道状态信息CSI报告配置信息，该CSI报告配置信息包括第一信息，该第一信息用于指示终端设备上报的目标CSI报告包括时域信道属性信息，并基于该网络配置信息上报目标CSI报告，提出了一种终端设备上报时域信道属性信息的技术方案，使得终端设备能够支持时域信道属性的上报。
上述主要从方法侧执行过程的角度对本申请实施例的方案进行了介绍。可以理解的是，网络设备为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所提供的实施例描述的各示例的单元及算法步骤，本申请能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用使用不同方法来实现所描述的功能，但是这种实现不应认为超出本申请的范围。
