Description

上报子配置的选择方法、装置、网络设备、终端和介质
本公开要求于2023年08月11日提交的申请号为202311013889.2、名称为“上报子配置的选择方法、装置、网络设备、终端和介质”的中国专利申请的优先权，该中国专利申请的全部内容通过引用全部并入本文。
技术领域
本公开涉及无线通信技术领域，尤其涉及一种信道状态信息参考信号测量上报子配置的选择方法、一种信道状态信息参考信号测量上报子配置的选择装置、一种网络设备和一种计算机可读存储介质。
背景技术
由于5G(5th Generation Mobile Communication Technology，第五代移动通信技术)网络的总能耗接近LTE(Long Term Evolution，长期演进)的4倍，因此亟需降低5G网络的整体能耗，而降低天线的功率是降低网络整体能耗的重要方向。
通过灵活关断天线端口和调节天线发射功率，能够降低天线的功率，以降低基站发送信号的网络能耗，为实现这样的灵活调整，需要对CSI(channel state information，信道状态信息)反馈机制进行相应的增强，在一次CSI配置中实现多种CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)资源配置，以供UE(User Equipment，用户终端)进行测量和上报，但是全部多个CSI测量结果的上报会对UE的复杂度和能耗带来影响。

具体实施方式
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的范例；相反，提供这些实施方式使得本公开将更加全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。所描述的特征、结构或特性可以以任何合适的方式结合在一个或更多实施方式中。
此外，附图仅为本公开的示意性图解，并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分，因而将省略对它们的重复描述。附图中所示的一些方框图是功能实体，不一定必须与物理或逻辑上独立的实体相对应。可以采用软件形式来实现这些功能实体，或在一个或多个硬件模块或集成电路中实现这些功能实体，或在不同网络和/或处理器装置和/或微控制器装置中实现这些功能实体。
本公开提供的方案，在需要对目标病例报告表进行数据分析时，通过确定与目标病例报告CSI-RS(Channel State Information-Reference Signal，信道状态信息参考信号)是5G NR(New Radio，新无线/新空口，即5G的无线网)系统中非常重要的一种参考信号，无线信道条件可能不断变化，终端需要将其看到的下行信道条件通过CSI(Channel State Information，信道状态信息)反馈给基站，以便基站在下行调度时将信道质量考虑在内，灵活关断天线端口和调节天线发射功率，其中，信道质量指示(CQI：Channel Quality Indicator)，秩指示(RI：Rank Indicator)和预编码指示(PMI：Precoder Matrix Indicator)，这三项合起来称为信道状态信息CSI。
由于5G网络的能耗高于4G网络，导致影响了5G网络的运营成本，因此需要降低 5G网络能耗，通过同时配置多个CSI资源并进行测量上报，灵活调整天线关断以及发射功率，可以有效降低基站天线能耗，但是终端同时对多个CSI测量和上报，一方面会导致终端复杂度的增加，另一方面会导致上报CSI的开销剧增，为防止这样的负面影响，需要对进行测量上报的CSI资源进行选择。
下面，将结合附图及实施例对本示例实施方式中的信道状态信息参考信号测量上报子配置的选择方法的各个步骤进行更详细的说明。
图1示出本公开实施例中一种信道状态信息参考信号测量上报子配置的选择方法流程图。
如图1所示，根据本公开的一个实施例的信道状态信息参考信号测量上报子配置的选择方法，一种信道状态信息参考信号测量上报子配置的选择方法，应用于基站，包括：
步骤S102，向终端发送多个信道状态信息CSI上报子配置的选择列表，选择列表用于选择多个CSI上报子配置中的至少一个，以使终端基于选择的CSI上报子配置进行CSI测量和上报。
其中，CSI上报子配置用于配置至少一个CSI-RS资源的上报，CSI子配置sub-configuration，指由具有相同特征的CSI-RS资源所构成的集合，这些特征可以是相同的天线端口数，也可以是发射功率偏移。
选择列表中指示的选择方式，可是直接对一个或多个CSI上报子配置进行指示，也可以通过对子配置范围的限定进行指示，假设共有N个CSI上报子配置sub-configuration，则选择列表中包含的指示标识最多可以有N个，或者是{n|X<＝n<＝Y}的集合，表示该sub-configuration被启用，与之关联的CSI-RS资源的相应配置需要被终端UE测量和上报。
在该实施例中，在通过设置选择列表，基于配置方式在选择列表中配置出所选择的上报子配置，以基于所选择的上报子配置确定配置的CSI-RS资源，针对CSI上报子配置中的CSI-RS配置或由多个CSI-RS资源配置构成的子配置进行CSI测量和上报，可以实现对CSI-RS子配置的指示和选择，可灵活进行天线端口和发射功率的选择，有利于降低用户端测量参考信号的复杂度和网络开销，以及提高CSI-RS测量资源配置的灵活度和可靠性。
在一个实施例中，多个CSI上报子配置sub-configuration基于CSI上报子配置sub-configuration机制配置，配置的每个CSI上报子配置sub-configuration对应于多个具有相同特征的信道状态信息参考信号CSI-RS资源。
其中，一个上报子配置sub-configuration中包括多个CSI-RS资源，另外，每个CSI-RS资源的配置只会存在于一个CSI上报子配置中。
在一个实施例中，选择列表包括至少一个选择标识，或选择列表记录有选择标识的取值范围，选择标识用于指示所选择的CSI上报子配置sub-configuration。
在该实施例中，通过在选择列表中配置选择标识，选择标识用于指示所选择的CSI上报子配置，以基于CSI上报子配置进一步确定所配置的CSI-RS资源，使终端不需要对所 有配置的CSI-RS资源进行测量，从而降低网络功耗。
在一个实施例中，在无线资源控制RRC信令中的CSI报告配置中配置具有对应关系的子标识和上报子配置sub-configuration。
在一个实施例中，选择标识包括为CSI上报子配置sub-configuration的子标识。
其中，在RRC资源配置中为每一个上报子配置sub-configuration增加子标识sub-ID，此时，sub-ID可直接作为选择标识。
在该实施例中，在当某个子标识sub-ID处于列表中时，则表示对应的上报子配置sub-configuration被启用，与之关联的CSI-RS资源的相应配置需要被UE测量和上报，从而保证了选择的灵活性和可靠性。
在一个实施例中，选择标识包括将CSI上报子配置sub-configuration的子标识进行排序的第一排序编号。
在该实施例中，为减少直接使用子标识sub-ID所占用的比特数，将子标识sub-ID按照一定方式排列进行编号，如子标识sub-ID递增或递减顺序，得到第一排序编号，作为选择标识，通过第一排序编号即可知对应的sub-configuration。
在一个实施例中，相同特征为多个CSI-RS资源具有相同的天线端口数，选择列表包括第一选择列表；第一选择列表包括至少一个第一选择标识，第一选择标识基于对天线端口数的选择生成。
示例性地，在一个实施例中，第一选择标识基于对天线端口数的选择生成的实现方式，包括：将多个CSI上报子配置sub-configuration对应的多个天线端口数进行排序，得到第二排序序号，第一选择标识包括第二排序序号。
在该实施例中，也可以不为CSI上报子配置对应配置sub-ID，此时可以直接对天线端口数进行升序/降序排列，得到第二排序序号，用第二排序序号直接作为第一选择标识，选择相应的相应sub-configuration。
示例性地，在另一个实施例中，第一选择标识基于对天线端口数的选择生成的实现方式，包括：第一选择标识包括天线端口数。
其中，CSI-RS resource的天线端口数可以是单个天线端口，也可以是多个天线端口，最多到32个天线端口，在多个天线端口映射的时候会用到CDM(Code Division Multiplexing，码分复用)，即多个CSI-RS资源可以在相同的时频资源上通过CDM的方式加以区分和映射。
在该实施例中，对于为支持不同的天线端口而配置的多个CSI-RS资源，此时在同一个sub-configuration对应的CSI-RS资源具备相同的端口数，故可用sub-configuration关联的天线端口数作为其唯一标记，在列表中填入具体的端口数量，则可指示不同的sub-configuration。
另外，本领域的技术人员能够理解的是，除了在列表中添加天线端口的具体数量外，还可以将列表内容修改为端口数量的取值范围，则天线端口数量在此范围内的sub- configuration均可被指示。
在一个实施例中，相同特征为多个CSI-RS资源具有相同的发射功率偏移值，选择列表包括第二选择列表；第二选择列表包括至少一个第二选择标识，第二选择标识基于对发射功率偏移值的选择生成。
在该实施例中，当同时存在一个CSI-RS资源中包含多个端口数量和发射功率偏移值时，CSI上报子配置可以仅以端口数量进行区分，但此时仍可选择对发射功率偏移，从而帮助指示最终要测量和上报的CSI-RS，则此时可直接选择的要选择的CSI-RS的功率偏移。
其中，发射功率偏移列表可复用基于发射功率的子配置选择列表字段。
在一个实施例中，将多个CSI上报子配置sub-configuration对应的多个发射功率偏移值进行排序，得到第三排序序号，第二选择标识包括第三排序序号。
在一个实施例中，第二选择标识包括发射功率偏移值。
如图2所示，在一个实施例中，向终端发送多个信道状态信息CSI上报子配置sub-configuration的选择列表，包括：
步骤S202，向终端发送RRC信令，RRC信令携带多个CSI上报子配置sub-configuration和选择列表。
在一个实施例中，在向终端发送RRC信令之后，还包括：
步骤S204，向终端发送CSI触发信令，以使终端基于CSI触发信令对选择的CSI上报子配置sub-configuration进行CSI测量和上报，其中，CSI触发信令包括媒体接入控制MAC控制元素CE和/或下行控制信息DCI。
其中，NR中支持三种上报类型，分别是周期性CSI、半持续NZP-CSI(Semi-Persistent CSI，SP-CSI)和非周期NZP-CSI(Aperiodic CSI,A-CSI)，分别即为P-CSI、SP-CSI和A-CSI，其中，P-CSI是RRC信令配置的不需要触发，当RRC信令配置之后，开始周期性的测量和上报。SP-CSI和P-CSI的区别在于需要触发，在RRC信令配置基本信息之后，需要等gNB再发送触发信息之后，才会周期性的测量和发送。在接收到触发信令之前，是不需要上报的。A-CSI就是触发一次，上报一次。
如图3所示，在一个实施例中，向终端发送多个信道状态信息CSI上报子配置sub-configuration的选择列表，包括：
步骤S302，向终端发送RRC信令，RRC信令携带多个CSI上报子配置sub-configuration。
步骤S304，向终端发送CSI触发信令，以使终端基于CSI触发信令对选择的CSI上报子配置sub-configuration进行CSI测量和上报，CSI触发信令携带选择列表，其中，CSI触发信令包括MAC CE和/或DCI。
在该实施例中，对于非周期NZP-CSI(Aperiodic CSI,A-CSI)和半持续NZP-CSI(Semi-Persistent CSI，SP-CSI)适用，该选择字段可位于激活CSI上报的DCI或MAC CE中，其 可选择的具体数值根据RRC中已经配置的CSI-RS资源配置自动获得。
引入sub-configuration的ID，则应在CSI report configuration的RRC配置中，与sub-configuration一同配置。
当有更多维度的sub-configuration被引入时，本专利仍然适用，但仍以基于端口数量的子配置作为选择基准，其他指示字段仅对其中的CSI-RS做进一步指示。
即使不存在sub-configuration机制，仍然可以通过本专利中的方法，基于configuration的配置直接进行选择。
如图4所示，根据本公开的另一个实施例的信道状态信息参考信号测量上报子配置sub-configuration的选择方法，应用于终端，包括：
步骤S402，接收基站发送的多个信道状态信息CSI上报子配置sub-configuration的选择列表，选择列表用于选择多个CSI上报子配置sub-configuration中的至少一个。
步骤S404，基于选择的CSI上报子配置sub-configuration进行CSI测量和上报。
在该实施例中，通过接收基站侧配置的选择列表，基于配置方式在选择列表中配置出所选择的上报子配置，以基于所选择的上报子配置确定配置的CSI-RS资源，针对CSI上报子配置中的CSI-RS配置或由多个CSI-RS资源配置构成的子配置进行CSI测量和上报，可以实现对CSI-RS子配置的指示和选择，可灵活进行天线端口和发射功率的选择，有利于降低终端测量参考信号的复杂度和网络开销。
在一个实施例中，多个CSI上报子配置sub-configuration基于CSI上报子配置sub-configuration机制配置，配置的每个CSI上报子配置sub-configuration对应于多个具有相同特征的CSI-RS资源，接收基站发送的多个信道状态信息CSI上报子配置sub-configuration的选择列表，还包括：提取选择列表中的选择标识，或选择标识的取值范围；基于选择标识或取值范围选择多个CSI上报子配置sub-configuration的至少一个。
在一个实施例中，选择标识包括为CSI上报子配置sub-configuration的子标识。
在一个实施例中，选择标识包括将CSI上报子配置sub-configuration的子标识进行排序的第一排序编号。
在一个实施例中，接收基站发送的RRC信令，还包括：在RRC信令中的CSI报告配置中提取对应的子标识和子配置sub-configuration；基于选择列表选择的子标识，确定所选择的子配置sub-configuration，以对子配置sub-configuration对应的CSI-RS资源进行测量。
在一个实施例中，相同特征为多个CSI-RS资源具有相同的天线端口数，选择列表包括第一选择列表；在第一选择列表提取至少一个第一选择标识，第一选择标识为天线端口数，或第一选择标识为第二排序序号，第二排序序号基于对多个CSI上报子配置sub-configuration对应的多个天线端口数进行排序生成。
在一个实施例中，相同特征为多个CSI-RS资源具有相同的发射功率偏移值，选择列表包括第二选择列表；第二选择列表包括至少一个第二选择标识，第二选择标识为发射功 率偏移值，或第二选择标识为第三排序序号，第三排序序号基于将多个CSI上报子配置sub-configuration对应的多个发射功率偏移值进行排序生成。
在一个实施例中，基于选择的CSI上报子配置进行CSI测量和上报，包括：将同时满足第一选择列表和第二选择列表的CSI-RS资源，作为选择的CSI上报子配置对应的CSI-RS资源。
示例性地，假设共有3个CSI上报子配置sub-configuration，选择标识分别为：#0，#1，#2，分别对应着16，8，24个天线端口，此时，选择列表中的配置信息为{#0，#1}或{16，8}，同时配置功率偏移列表为{#0，#2}或{-3，3}，则表示端口数位16/8的sub-configuration被选择，但只需要对其中发射功率偏移值可设置为3/-3的CSI-RS进行测量和上报，即同时满足第一选择列表和第二选择列表的CSI-RS资源。
在一个实施例中，接收基站发送的多个信道状态信息CSI上报子配置sub-configuration的选择列表，包括：接收基站发送的RRC信令，RRC信令多个CSI上报子配置sub-configuration和选择列表。
在一个实施例中，在接收基站发送的RRC信令之后，还包括：接收基站发送的CSI触发信令；基于CSI触发信令对选择的CSI上报子配置sub-configuration进行CSI测量和上报，其中，CSI触发信令包括媒体接入控制MAC控制元素CE和/或下行控制信息DCI。
在一个实施例中，接收基站发送的多个信道状态信息CSI上报子配置sub-configuration的选择列表，包括：接收基站发送的RRC信令，RRC信令携带多个CSI上报子配置sub-configuration；接收基站发送的CSI触发信令，以基于CSI触发信令对选择的CSI上报子配置sub-configuration进行CSI测量和上报，CSI触发信令携带选择列表，其中，CSI触发信令包括媒体接入控制MAC控制元素CE和/或下行控制信息DCI。
如图5所示，根据本公开的另一种信道状态信息参考信号测量上报子配置的选择方法，包括：
步骤S502，通过CSI资源配置信令CSI-ResourceConfig为终端配置CSI-RS资源。
步骤S504，为终端配置多个CSI上报子配置以及对应子标识，每个CSI上报子配置对应于多个具有相同特征的CSI-RS资源。
步骤S506，基于向终端发送的选择列表确定选择的子标识，以基于选择的子标识，在DCI或MAC CE信令触发激活时，由终端进行相应的CSI测量及上报。
根据本公开的又一个实施例的信道状态信息参考信号测量上报子配置的选择方法，基于CSI反馈的天线端口动态调整。
为实现网络天线动态调整进行节能，引入增强的CSI反馈机制，在CSI Resource configuration的RRC配置中，在CSI-RSResourceSet内，为2个CSI-RS资源分别配置了2个端口数量，对于CSI-RS#1，其端口数分别为{4，8}；对于CSI-RS#2，其端口分别为{8，12}，共形成了3个子配置，分别为：
sub#1(#port＝4)：{CSI-RS#1}；
sub#2(#port＝8)：{CSI-RS#1，CSI-RS#2}；
sub#3(#port＝12)：{CSI-RS#2}。
若通过MAC CE触发，则列表中的内容为{#2}，则只有sub#2中的CSI-RS配置被要求测量和上报。
根据本公开的又一个实施例的信道状态信息参考信号测量上报子配置的选择方法，基于CSI反馈的天线端口和发射功率联合动态调整。
为实现网络天线及功率动态调整进行节能，引入增强的CSI反馈机制。在CSI Resource configuration的RRC配置中，在CSI-RSResourceSet内，一个CSI-RS资源内配置同时配置了2个CSI-RS，分别对应了32端口和16端口的CSI-RS，采用的发射功率偏移为{1dB(#1)，3dB(#2)}；相同set内的另一CSI-RS资源也配置了一个CSI-RS资源，对应16端口，同时发射功率偏移为1dB(#1)。
此时的子配置仍只有2个：分别是sub#1(#port＝16)：{CSI-RS#1，CSI-RS#2}；sub#2(#port＝32)：{CSI-RS#1}。
若通过MAC CE触发，则指示端口数的列表为{#1}，指示发射功率偏移的列表为{3}，则sub#1被测量和上报，且只有其中发射功率偏移等于3dB的CSI-RS资源被测量，即只有CSI-RS#1中发射功率偏移为3dB情况被测量和上报。
