Description

用户设备、电子设备、无线通信方法和存储介质
本申请要求于2022年4月1日提交中国专利局、申请号为202210339010.2、发明名称为“用户设备、电子设备、无线通信方法和存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开的实施例总体上涉及无线通信领域，具体地涉及用户设备、电子设备、无线通信方法和计算机可读存储介质。更具体地，本公开涉及一种无线通信系统中的用户设备、一种作为无线通信系统中的网络侧设备的电子设备、一种由无线通信系统中的用户设备执行的无线通信方法、一种由无线通信系统中的网络侧设备执行的无线通信方法以及一种计算机可读存储介质。
背景技术
用户设备可以装备多个天线面板，简称面板(panel)，以覆盖多个不同的方向。例如，用户设备的每一个面板朝向一个方向、发送一个或多个波束。用户设备可以利用用户能力值集合(UE capability value set)来向网络侧设备上报用户设备的多个面板，每个用户能力值集合对应一个面板。用户能力值集合可以包括一个或多个用户能力值。而在现有的协议中规定，用户设备不能上报用户能力值相同的两个用户能力值集合。也就是说，如果用户设备具有两个面板，这两个面板的用户能力值集合中的用户能力值相同，则用户设备不能向网络侧设备同时上报这两个面板，即网络侧设备不能同时调度这两个面板。这样一来，大大限制了在上行传输中调度多个面板的应用场景。
此外，在现有的协议中，在用户设备装备多个天线面板的场景中，在用户设备向网络侧设备上报波束质量信息之后，网络侧设备是否需要发送反馈信息、以及如何发送反馈信息还没有定论。进一步，在网络侧设备确定为用户设备的上行传输调度多个面板的情况下，如何实现上行调度也是需要解决的技术问题之一。
因此，有必要提出一种技术方案，以优化用户设备的多面板上行传 输过程。

根据本公开的另一方面，提供了一种计算机程序，所述计算机程序当被计算机执行时使得所述计算机执行根据本公开所述的无线通信方法。

将按照以下顺序进行描述：
1.问题的描述；
2.用户设备的配置示例；
3.网络侧设备的配置示例；
4.方法实施例；
5.应用示例。
<1.问题的描述>
前文中提到，在现有的协议中规定，用户设备不能上报用户能力值相同的两个用户能力值集合，大大限制了在上行传输中调度多个面板的应用场景。另外，现有的协议并未规定将天线面板的哪个或者哪些参数用作用户能力值集合中的用户能力值。此外，在现有的协议中，在用户设备向网络侧设备上报波束质量信息之后，网络侧设备是否需要发送反馈信息、 以及如何发送反馈信息也没有定论。进一步，在现有的协议中也没有关于如何实现在上行传输中调度多个面板的细节。
本公开针对这样的场景提出了一种无线通信系统中的电子设备、由无线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，以优化用户设备的多面板上行传输过程。
根据本公开的无线通信系统可以是5G NR通信系统，也可以是6G或者更高等级的通信系统。
根据本公开的网络侧设备可以是基站设备，例如可以是eNB，也可以是gNB(第5代通信系统中的基站)。
根据本公开的用户设备可以是移动终端(诸如智能电话、平板个人计算机(PC)、笔记本式PC、便携式游戏终端、便携式/加密狗型移动路由器和数字摄像装置)或者车载终端(诸如汽车导航设备)。用户设备还可以被实现为执行机器对机器(M2M)通信的终端(也称为机器类型通信(MTC)终端)。此外，用户设备可以为安装在上述终端中的每个终端上的无线通信模块(诸如包括单个晶片的集成电路模块)。此外，根据本公开的用户设备可以装备多个天线面板。
<2.用户设备的配置示例>
图1是示出根据本公开的实施例的用户设备100的配置的示例的框图。
如图1所示，用户设备100可以包括生成单元110和通信单元120。
这里，用户设备100的各个单元都可以包括在处理电路中。需要说明的是，用户设备100既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，生成单元110可以生成面板信息。这里，面板信息可以包括用户设备100的多个面板中的每个面板的用户能力值集合.进一步，不同的面板的用户能力值集合中的用户能力值(UE capability value)相同或不相同。
根据本公开的实施例，用户设备100可以通过通信单元120将面板信息发送至网络侧设备。这里的网络侧设备可以是为用户设备100提供服 务的网络侧设备。
由此可见，根据本公开的实施例的用户设备100，上报的面板信息中，不同的面板的用户能力值集合中的用户能力值相同或者不相同。也就是说，本公开取消了用户设备不能上报用户能力值相同的两个面板的限制，即取消了对多面板上行传输的限制，从而使得用户设备能够上报任意的面板，进而优化了用户设备的多面板上行传输过程。
根据本公开的实施例，如图1所示，用户设备100还可以包括相干类型确定单元130，用于确定用户设备100的所有面板中的每个面板的面板内相干类型。进一步，生成单元110可以将面板内相干类型作为一个用户能力值从而被包括在该面板的用户能力值集合中。
根据本公开的实施例，面板内相干类型表示面板的多个端口之间的相干情况，面板的多个端口之间的相干情况包括完全相干、部分相干和非相干。
根据本公开的实施例，在面板的所有SRS端口中的任意两个SRS端口均相干的情况下，相干类型确定单元130可以确定该面板的面板内相干类型为完全相干。这里，两个SRS端口相干指的是两个SRS端口之间的相位差恒定，因此两个SRS端口可以使用相同的预编码矩阵。也就是说，在完全相干的情况下，该面板的所有SRS端口均使用相同的预编码矩阵。例如，面板A具有4个SRS端口，编号为1-4，这4个SRS端口的任意两个SRS端口都相干，即4个SRS端口使用相同的预编码矩阵a，则面板A的面板内相干类型为完全相干。
根据本公开的实施例，在面板的所有SRS端口中的任意两个SRS端口均不相干的情况下，相干类型确定单元130可以确定该面板的面板内相干类型为非相干。这里，两个SRS端口不相干指的是两个SRS端口之间的相位差非恒定，即随时间变化，因此两个SRS端口使用不同的预编码矩阵。也就是说，在非相干的情况下，该面板的所有SRS端口均使用不同的预编码矩阵。例如，面板B具有4个SRS端口，编号为1-4，这4个SRS端口的任意两个SRS端口都不相干，即4个SRS端口分别使用不同的预编码矩阵a、b、c和d，则面板B的面板内相干类型为非相干。
根据本公开的实施例，在面板的所有SRS端口中存在部分的相干的SRS端口的情况下，相干类型确定单元130可以确定该面板的面板内相干类型为部分相干。也就是说，在部分相干的情况下，该面板的所有SRS 端口中有部分SRS端口使用相同的预编码矩阵。例如，面板C具有4个SRS端口，编号为1-4，这4个SRS端口中的端口1和2相干，使用相同的预编码矩阵a，端口3使用预编码矩阵b，端口4使用预编码矩阵c，则面板C的面板内相干类型为部分相干。
根据本公开的实施例，在面板的多个端口部分相干的情况下，面板的多个端口之间的相干情况还包括部分相干的端口。例如，在面板C中的端口1和2相干的情况下，面板的多个端口之间的相干情况还可以包括表示1和2相干的信息，即用户能力值不仅包括表示部分相干的信息，还包括该面板的部分相干的端口。
根据本公开的实施例，用户能力值还可以包括SRS端口的数目，即生成单元110可以将面板的SRS端口的数目作为一个用户能力值从而被包括在该面板的用户能力值集合中。也就是说，每个面板的用户能力值集合都可以包括两个用户能力值：SRS端口的数目；以及面板内相干类型。
根据本公开的实施例，每个面板的用户能力值集合可以包括一个或多个用户能力值。两个面板的用户能力值集合中的用户能力值相同指的是这两个面板的用户能力值集合中的所有用户能力值均相同，否则这两个面板的用户能力值集合中的用户能力值不同。此外，根据本公开的实施例，在两个面板的用户能力值集合中的用户能力值相同的情况下，也可以说这两个面板的用户能力值集合相同。
也就是说，在每个面板的用户能力值集合包括SRS端口的数目以及面板内相干类型的情况下，在两个面板的SRS端口的数目以及面板内相干类型这两个用户能力值分别相同的情况下，这两个面板的用户能力值集合相同，否则这两个面板的用户能力值集合不同。例如，面板D和面板E的SRS端口的数目相同，面板D的面板内相干类型为部分相干，其中端口1和2相干，端口3和4相干，面板E的面板内相干类型为部分相干，其中端口1和4相干，端口2和3相干，则面板D和面板E的用户能力值集合不同。再如，面板F和面板G的SRS端口的数目相同，面板F的面板内相干类型为完全相干，面板G的面板内相干类型为完全相干，则面板F和面板G的用户能力值集合相同。
如上所述，根据本公开的实施例，可以将面板的SRS端口的数目和/或面板内相干类型作为用户能力值从而包括在面板的用户能力值集合中。也就是说，本公开定义了两种可以用作用户能力值的参数。
根据本公开的实施例，在如上所述确定了用户设备100的所有面板中的每个面板的用户能力值集合之后，生成单元110可以将每个面板的用户能力值集合包括在面板信息中。
由此可见，根据本公开的实施例，不管用户能力值集合是否相同，用户设备都可以将该面板上报至网络侧设备，即网络侧在调度多面板时没有任何限制。
根据本公开的实施例，在上报面板信息之后，用户设备100可以通过通信单元120从网络侧设备接收RRC配置信息。
根据本公开的实施例，如图1所示，用户设备100还可以包括测量单元140，用于根据来自网络侧设备的参考信号对各个波束的信道质量进行测量。这里，用户设备100可以装备有多个面板，每个面板包括一个或多个波束，从而测量单元140可以对各个面板的各个波束的信道质量进行测量。
本公开对表示信道质量的参数不作任何限定。例如，可以用L1-RSRP(Lay 1-Reference Signal Receiving Power，层1参考信号接收功率)或者L1-SINR(Lay 1-Signal to Interference plus Noise Ratio，层1信干噪比)来表示各个波束的信道质量。
根据本公开的实施例，如图1所示，用户设备100还可以包括选择单元150，用于选择每个面板的优选波束，即针对每个面板选择信道质量最优的波束。
根据本公开的实施例，生成单元110还可以针对每个面板生成波束质量信息，波束质量信息包括该面板的优选波束，从而用户设备100可以通过通信单元120将波束质量信息发送至网络侧设备。
根据本公开的实施例，可以用面板指示信息和波束指示信息来表示面板的优选波束。进一步，由于面板与用户能力值集合存在一一对应的关系，因此可以用用户能力值集合的标识信息(UE capability value set ID)来表示面板指示信息。此外，由于网络侧设备的下行参考信号与波束存在一一对应的关系，因此可以用CRI(CSI-RS resource indicator，CSI-RS资源指示)或者SSBRI(SSB(Synchronization Signal block，同步信号块)resource indicator，SSB资源指示)来表示波束指示信息。也就是说，每个面板的波束质量信息可以包括面板指示信息和波束指示信息。
根据本公开的实施例，相干类型确定单元130还可以确定每个面板 的面板间相干类型，并且生成单元110可以将面板间相干类型包括在波束质量信息中。
根据本公开的实施例，面板的面板间相干类型可以表示该面板与其他面板之间的相干情况，该面板与其他面板之间的相干情况包括非相干和相干。
根据本公开的实施例，如果面板X的面板内相干类型为完全相干，面板Y的面板内相干类型为完全相干，且面板X的各个端口与面板Y的各个端口之间的相位差恒定，则面板X的面板间相干类型为相干，面板Y的面板间相干类型为相干。此时，面板X的各个端口与面板Y的各个端口可以使用相同的预编码矩阵。
针对每个面板，相干类型确定单元130可以确定用户设备100中是否存在与该面板相干的其他面板。如果不存在与该面板相干的其他面板，则该面板的面板间相干类型为非相干。如果存在与该面板相干的其他面板，则该面板的面板间相干类型为相干。进一步，在存在与该面板相干的其他面板的情况下，该面板与其他面板之间的相干情况还包括与该面板相干的其他面板的信息。例如，可以用用户能力值集合的标识信息来表示其他面板。例如，在面板X与面板Y相干，则面板X的面板间相干类型为相干，并且面板X的面板间相干类型包括面板Y的信息；面板Y的面板间相干类型为相干，并且面板Y的面板间相干类型包括面板X的信息。
根据本公开的实施例，生成单元110还可以将面板的优选波束的信道质量信息包括在波束质量信息中。信道质量信息包括但不限于L1-RSRP和L1-SINR。
如上所述，生成单元110可以针对每个面板生成波束质量信息，波束质量信息可以包括以下中的一种或多种：该面板的面板间相干类型；该面板的优选波束；该面板的优选波束的信道质量信息。
如上所述，根据本公开的实施例，用户设备100在向网络侧设备上报波束质量信息时，可以上报面板间相干类型。此外，用户设备100在向网络侧设备上报面板信息时，可以上报面板内相干类型。这样一来，可以便于网络侧设备根据各个面板的面板内相干类型和面板间相干类型来为用户设备100调度用于上行传输的面板并为各个面板确定预编码矩阵。
根据本公开的实施例，在用户设备100向网络侧设备发送波束质量信息之后，用户设备100可以通过通信单元120从网络侧设备接收针对波 束质量信息的反馈信息。
根据本公开的实施例，如图1所示，用户设备100还可以包括解码单元160，用于对反馈信息进行解码以确定网络侧设备是否接收到波束质量信息。
根据本公开的实施例，用户设备100可以利用PUCCH，例如PUCCH中的UCI(Uplink Control Information，上行控制信息)发送波束质量信息。在这种情况下，网络侧设备可以利用DCI格式0(DCI format 0)或DCI格式2(DCI format 2)发送反馈信息，从而解码单元160对反馈信息进行解码以确定ACK和NACK。在解码单元160确定ACK的情况下，用户设备100可以确定网络侧设备接收到波束质量信息；在解码单元160确定NACK的情况下，用户设备100可以确定网络侧设备没有接收到波束质量信息。下面将详细描述网络侧设备利用DCI格式0和DCI格式2发送反馈信息的两种情形。
根据本公开的实施例，网络侧设备可以利用DCI格式0，例如DCI格式0_1来发送反馈信息。具体地，当用户设备100获得DCI格式0_1的信息之后，可以根据DFI(Downlink Feedback Information，下行反馈信息)标志来确定该信息是针对PUSCH、PUCCH还是PUSCH和PUCCH的反馈，进而根据PUCCH的HARQ-ACK比特图、或者根据PUSCH和PUCCH的HARQ-ACK比特图来确定ACK或者NACK。
图2是示出根据本公开的实施例的网络侧设备利用DCI格式0_1发送反馈信息的示例图。如图2所示，DCI格式0_1包括DCI格式的标识、载波指示、DFI标志、HARQ-ACK比特图、TPC(Transmit Power Control，传输功率控制)以及预留位。在DFI标志为01的情况下，HARQ-ACK比特图表示针对PUSCH的HARQ-ACK比特图，TPC表示针对PUSCH的TPC；在DFI标志为10的情况下，HARQ-ACK比特图表示针对PUCCH的HARQ-ACK比特图，TPC表示针对PUCCH的TPC；在DFI标志为11的情况下，HARQ-ACK比特图表示针对PUSCH和PUCCH的HARQ-ACK比特图，TPC表示针对PUSCH和PUCCH的TPC；在DFI标志为00的情况下，没有HARQ-ACK比特图、TPC以及预留位信息，表示上行调度准许(Uplink grant)信息。
如上所述，在用户设备100利用PUCCH发送波束质量信息、并且网络侧设备发送ACK或者NACK的情况下，网络侧设备可以对DCI格式0_1进行重用从而承载反馈信息，仅需要对DCI格式0_1进行很小的改动 就可以实现反馈信息的承载。
根据本公开的实施例，网络侧设备可以利用DCI格式2，例如DCI格式2_x来发送反馈信息。具体地，当用户设备100获得DCI格式2_x的信息之后，可以根据用户设备100发送波束质量信息的PUCCH的资源从而从针对所有PUCCH资源的HARQ-ACK码本中确定用户设备100的反馈信息，进而确定ACK或者NACK。
图3是示出根据本公开的实施例的网络侧设备利用DCI格式2_x发送反馈信息的示例图。如图3所示，DCI格式2_x包括PUCCH资源1至PUCCH资源N、以及针对PUCCH资源1-N的HARQ-ACK码本。
如上所述，在用户设备100利用PUCCH发送波束质量信息、并且网络侧设备发送ACK或者NACK的情况下，网络侧设备可以新设计DCI格式2_x来承载反馈信息。进一步，用户设备100可以利用专用于DCI格式2_x的RNTI(Radio Network Tempory Identity，无线网络临时标识)来对该DCI格式进行解码。
根据本公开的实施例，用户设备100可以利用PUCCH，例如PUCCH中的UCI(Uplink Control Information，上行控制信息)发送波束质量信息。在这种情况下，网络侧设备可以利用DCI格式1(DCI format 1)，例如DCI格式1_1和DCI格式1_2发送反馈信息，从而解码单元160对反馈信息进行解码以确定NACK。在解码单元160确定NACK的情况下，用户设备100可以确定网络侧设备没有接收到波束质量信息，在用户设备100没有收到NACK的情况下，用户设备100可以确定网络侧设备接收到波束质量信息。这样一来，网络侧设备可以只反馈NACK，从而大大减少信令开销。下面将详细描述网络侧设备利用DCI格式1_1和DCI格式1_2发送反馈信息的两种情形。
根据本公开的实施例，网络侧设备可以利用DCI格式1_1中的一个或多个字段的某个特定值来表示NACK反馈信息。例如，网络侧设备可以利用RV(Redundancy Version，冗余版本)字段、MCS(Modulation and Coding Scheme，调制编码方案)字段和FDRA(Frequency Domain Resource Assignment，频域资源分配)字段中的一个或多个的特定值来表示NACK。作为一个非限制性示例，当用户设备100根据DCI格式1_1确定RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0时，用户设备100可以确定NACK，即网络侧设备没有接收到波束质量信息，否则确定网络侧设备接收到波束质量信息。
图4是示出根据本公开的实施例的网络侧设备利用DCI格式1_1发送反馈信息的示例图。如图4所示，DCI格式1_1包括DCI格式的标识、载波指示、RV字段、MCS字段、FDRA字段和PUCCH资源指示。在RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0的情况下，用户设备100可以确定接收到NACK信息。
根据本公开的实施例，网络侧设备可以利用DCI格式1_2中的一个或多个字段的某个特定值来表示NACK反馈信息。例如，网络侧设备可以利用RV(Redundancy Version，冗余版本)字段、MCS(Modulation and Coding Scheme，调制编码方案)字段和FDRA(Frequency Domain Resource Assignment，频域资源分配)字段中的一个或多个的特定值来表示NACK。作为一个非限制性示例，当用户设备100根据DCI格式1_2确定RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0时，用户设备100可以确定NACK，即网络侧设备没有接收到波束质量信息，否则确定网络侧设备接收到波束质量信息。
图5是示出根据本公开的实施例的网络侧设备利用DCI格式1_2发送反馈信息的示例图。如图5所示，DCI格式1_2包括DCI格式的标识、载波指示、RV字段、MCS字段、FDRA字段和PUCCH资源指示。在RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0的情况下，用户设备100可以确定接收到NACK信息。
值得注意的是，如上虽然描述了利用RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0的情况指示NACK信息的实施例，但是该实施例并不是限制性的。网络侧设备可以利用字段的其他组合、以及字段的其他特定值来表示NACK。
如上所述，根据本公开的实施例，在用户设备100利用PUCCH来传输波束质量信息，并且网络侧设备只反馈NACK而不反馈ACK的情况下，网络侧设备可以利用通过重用DCI格式1来承载反馈信息。
根据本公开的实施例，用户设备100可以利用PUSCH，例如PUSCH中的UCI或MAC CE发送波束质量信息。在这种情况下，网络侧设备可以利用DCI格式0(DCI format 0)，例如DCI格式0_0和DCI格式0_1发送反馈信息，从而解码单元160对反馈信息进行解码以确定反馈信息。
具体地，网络侧设备可以利用DCI格式0_0或DCI格式0_1中的上行调度准许中的NDI(New Data indicator，新数据指示)字段的内容来表 示ACK或者NACK。当用户设备100接收到DCI格式0_0或DCI格式0_1之后，可以根据NDI字段的值来确定网络侧设备是否接收到波束质量信息。例如，当NDI字段的值为1时，表示ACK消息，即网络侧设备接收到波束质量信息；当NDI字段的值为0时，表示NACK消息，即网络侧设备没有接收到波束质量信息。进一步，用户设备100可以根据HARQ进程的标识信息(HARQ process ID)来确定与发送的波束质量信息相对应的NDI。
如上所述，根据本公开的实施例，在用户设备100利用PUSCH来传输波束质量信息的情况下，网络侧设备可以通过DCI格式0中的HARQ进程的标识信息和NDI字段来承载反馈信息。
根据本公开的实施例，在用户设备100确定网络侧设备没有接收到波束质量信息的情况下，用户设备100可以对波束质量信息进行重传。
如上所述，本公开认为网络侧设备需要对用户设备100发送的波束质量信息进行反馈。进一步，本公开设计了网络侧设备发送反馈信息的细节，从而提高波束质量信息的可靠性。
根据本公开的实施例，用户设备100还可以通过通信单元120从网络侧设备接收上行调度信息。例如，用户设备100可以根据DCI格式0接收上行调度信息。
根据本公开的实施例，上行调度信息可以包括多个SRI(SRS Resource Indicator，SRS资源指示)。如图1所示，用户设备100还可以包括面板确定单元170，用于根据上行调度信息中的多个SRI确定用于上行传输的多个面板。
根据本公开的实施例，SRI可以用于指示一个SRS资源集合(SRS Resource Set)中的一个SRS资源(SRS Resource)，而SRS资源与上行波束具有一一对应的关系，因此可以用于指示用户设备100的某个特定波束，即可以用于指示用户设备100的某个特定面板。也就是说，面板确定单元170可以根据每个SRI确定一个面板，从而可以根据多个SRI确定多个面板。
根据本公开的实施例，上行调度信息也可以包括一个SRI，面板确定单元170用于根据上行调度信息中的一个SRI确定用于上行传输的多个面板。
根据本公开的实施例，可以在用户设备100与网络侧设备之间预设 波束组合与SRI的映射关系。也就是说，可以将不同的面板上的波束的各种组合都列举出来，每个组合与一个SRI具有映射关系。这样一来，用户设备100可以根据上行调度信息中的一个SRI确定波束组合，即确定多个SRS资源集合中的多个SRS资源，从而确定多个波束，进而确定多个波束所在的面板。
由此可见，用户设备100可以根据来自网络侧设备的上行调度信息确定网络侧设备调度的多个面板上的多个波束。
根据本公开的实施例，上行调度信息还可以包括TPMI(Transmission Precoder Matrix Index，传输预编码矩阵索引)。如图1所示，用户设备100还可以包括预编码矩阵确定单元180，用于根据上行调度信息中的TPMI确定网络侧设备调度的多个面板的预编码矩阵。
根据本公开的实施例，在上行调度信息包括一个TPMI的情况下，说明网络侧设备调度的多个面板之间是相干的关系，因此这多个面板可以使用相同的预编码矩阵。因此，预编码矩阵确定单元180可以将该TPMI指示的预编码矩阵用作多个面板的预编码矩阵。
根据本公开的实施例，在上行调度信息包括多个TPMI的情况下，说明网络侧设备调度的多个面板之间是非相干的关系，因此多个面板使用不同的预编码矩阵。进一步，预编码矩阵确定单元180还可以根据调度的各个面板的面板内相干类型确定各个面板的预编码矩阵的数目，即TPMI的数目。也就是说，在面板内相干类型为完全相干的情况下，该面板的所有端口使用相同的预编码矩阵，即TPMI的数目为1；在面板内相干类型为非相干的情况下，该面板的所有端口使用不同的预编码矩阵，即TPMI的数目与端口的数目相同；在面板内相干类型为部分相干的情况下，该面板的相干的端口使用相同的预编码矩阵，不相干的端口使用不同的预编码矩阵。
例如，网络侧设备调度了面板A和面板B，面板A和面板B相干，则用户设备100可以根据一个TPMI确定一个预编码矩阵，面板A的所有端口和面板B的所有端口都使用该预编码矩阵。再如，网络侧设备调度了面板C和面板D，面板C和面板D非相干，面板C的面板内相干关系为完全相干，面板D的面板内相干关系为非相干、且面板D具有2个端口，则用户设备可以根据3个TPMI确定3个预编码矩阵，其中面板C的所有端口使用预编码矩阵1，面板D的2个端口分别使用预编码矩阵2和预编码矩阵3。又如，网络侧设备调度了面板E和面板F，面板E和面板F非 相干，面板E的面板内相干关系为完全相干，面板F的面板内相干关系为部分相干、且面板F具有4个端口，其中端口a和b相干，则用户设备可以根据4个TPMI确定4个预编码矩阵，其中面板E的所有端口使用预编码矩阵1，面板F的端口a和b使用预编码矩阵2，端口c使用预编码矩阵3，端口d使用预编码矩阵4。
这里，网络侧设备例如可以通过波束质量信息中的面板间相干类型来确定各个面板之间的相干关系，并且通过面板信息中的面板内相干类型类确定各个面板的端口之间的相干关系，从而确定各个面板所需要的预编码矩阵的数目。
如上所述，根据本公开的实施例，用户设备100可以通过网络侧设备的上行调度信息确定调度的多个天线面板的各个端口所使用的预编码矩阵。
如上所述，本公开对网络侧设备同时调度用户设备100的多个面板的细节进行了设计，从而使得网络侧设备可以利用上行调度信息同时调度多个面板，并为多个面板配置预编码矩阵。
由此可见，根据本公开的实施例，不管用户能力值集合是否相同，用户设备100都可以将该面板上报至网络侧设备，即网络侧在调度多面板时没有任何限制。此外，本公开定义了用户能力值集合中的两个用户能力值：SRS端口的数目和面板内相干类型。进一步，本公开认为网络侧设备需要对用户设备100发送的波束质量信息进行反馈，并且设计了网络侧设备发送反馈信息的细节，从而提高波束质量信息的可靠性。此外，本公开对网络侧设备同时调度用户设备100的多个面板的细节进行了设计，从而使得网络侧设备可以利用上行调度信息同时调度多个面板，并为多个面板配置预编码矩阵。综上，本公开优化了用户设备100的多面板上行传输过程。

图6是示出根据本公开的实施例的无线通信系统中的用作网络侧设备的电子设备600的结构的框图。这里的电子设备600例如可以为基站设备。
如图6所示，电子设备600可以包括通信单元610和确定单元620。
这里，电子设备600的各个单元都可以包括在处理电路中。需要说明的是，电子设备600既可以包括一个处理电路，也可以包括多个处理电 路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。

如上所述，根据本公开的实施例，面板信息中不同的面板的用户能力值集合中的用户能力值相同或者不相同。也就是说，本公开取消了用户设备不能上报用户能力值相同的两个面板的限制，即取消了对多面板上行传输的限制，从而使得用户设备能够上报任意的面板，从而电子设备600可以调度任意的面板，进而优化了用户设备的多面板上行传输过程。
根据本公开的实施例，确定单元620可以根据用户能力值集合确定其中包括的一个或多个用户能力值。这里，用户能力值可以包括面板内相干类型，面板内相干类型表示面板的多个端口之间的相干情况，面板的多个端口之间的相干情况包括完全相干、部分相干和非相干。也就是说，确定单元620可以根据来自用户设备的面板信息确定各个面板的面板内相干类型，即完全相干、部分相干和非相干。

根据本公开的实施例，每个面板的波束质量信息可以包括面板指示信息和波束指示信息，确定单元620可以根据波束质量信息中的面板指示信息和波束指示信息来确定各个面板的优选波束。进一步，由于面板与用户能力值集合存在一一对应的关系，因此可以用用户能力值集合的标识信息(UE capability value set ID)来表示面板指示信息，从而确定单元620可以根据用户能力值集合的标识信息来确定面板。此外，由于网络侧设备的下行参考信号与波束存在一一对应的关系，因此可以用CRI或者SSBRI来表示波束指示信息，从而确定单元可以根据CRI或者SSBRI来确定波束。
根据本公开的实施例，确定单元620还可以根据波束质量信息确定面板的优选波束的信道质量信息，例如L1-SINR或者L1-RSRP。
根据本公开的实施例，确定单元620可以根据波束质量信息确定面板的面板间相干类型，面板间相干类型表示面板与其他面板之间的相干情况，面板与其他面板之间的相干情况包括非相干和相干。进一步，在面板与其他面板相干的情况下，面板与其他面板之间的相干情况还包括与面板相干的其他面板的信息。也就是说，确定单元620可以根据面板间相干类型确定是否存在与该面板相干的其他面板，并且在存在与该面板相干的其他面板的情况下，确定单元620还可以确定与该面板相干的其他面板。例如，确定单元620可以根据用户能力值集合的标识信息来确定其他面板。
根据本公开的实施例，如图6所示，电子设备600还可以包括生成单元630，用于生成针对波束质量信息的反馈信息。进一步，电子设备600可以通过通信单元610将反馈信息发送至用户设备。
根据本公开的实施例，在用户设备通过PUCCH发送波束质量信息的情况下，电子设备600可以利用DCI格式0或DCI格式2承载反馈信息，反馈信息包括ACK和NACK。也就是说，在电子设备600成功接收波束质量信息的情况下，生成单元630生成ACK；在电子设备600未成功接收波束质量信息的情况下，生成单元630生成NACK。
根据本公开的实施例，电子设备600可以利用DCI格式0，例如DCI格式0_1来发送反馈信息。具体地，电子设备600可以利用DFI标志来表 示该信息是针对PUSCH、PUCCH还是PUSCH和PUCCH的反馈，并且根据反馈信息生成PUCCH的HARQ-ACK比特图、或者生成PUSCH和PUCCH的HARQ-ACK比特图。具体地，如图2所示，DCI格式0_1包括DCI格式的标识、载波指示、DFI标志、HARQ-ACK比特图、TPC以及预留位。在DFI标志为01的情况下，HARQ-ACK比特图表示针对PUSCH的HARQ-ACK比特图，TPC表示针对PUSCH的TPC；在DFI标志为10的情况下，HARQ-ACK比特图表示针对PUCCH的HARQ-ACK比特图，TPC表示针对PUCCH的TPC；在DFI标志为11的情况下，HARQ-ACK比特图表示针对PUSCH和PUCCH的HARQ-ACK比特图，TPC表示针对PUSCH和PUCCH的TPC；在DFI标志为00的情况下，没有HARQ-ACK比特图、TPC以及预留位信息，表示上行调度准许(Uplink grant)信息。
如上所述，在用户设备利用PUCCH发送波束质量信息、并且电子设备600发送ACK或者NACK的情况下，电子设备600可以对DCI格式0_1进行重用从而承载反馈信息，仅需要对DCI格式0_1进行很小的改动就可以实现反馈信息的承载。
根据本公开的实施例，电子设备600可以利用DCI格式2，例如DCI格式2_x来发送反馈信息。具体地，生成单元可以根据反馈信息以及用户设备发送波束质量信息的PUCCH的资源来确定针对所有PUCCH资源的HARQ-ACK码本。也就是说，针对所有PUCCH资源的HARQ-ACK码本可以包括电子设备600服务的多个用户设备的反馈信息。具体地，如图3所示，DCI格式2_x包括PUCCH资源1至PUCCH资源N、以及针对PUCCH资源1-N的HARQ-ACK码本。
如上所述，在用户设备利用PUCCH发送波束质量信息、并且电子设备600发送ACK或者NACK的情况下，电子设备600可以新设计DCI格式2_x来承载反馈信息。进一步，电子设备600可以分配一个新的RNTI(Radio Network Tempory Identity，无线网络临时标识)来对新设计的DCI格式2_x进行加扰。
根据本公开的实施例，在用户设备通过PUCCH发送波束质量信息的情况下，电子设备600可以利用DCI格式1承载反馈信息，反馈信息包括NACK。也就是说，在电子设备600成功接收波束质量信息的情况下，不发送反馈信息；在电子设备600未成功接收波束质量信息的情况下，生成单元630生成NACK。
根据本公开的实施例，电子设备600可以利用DCI格式1_1或者DCI格式1_2中的一个或多个字段的某个特定值来表示NACK反馈信息。例如，电子设备600可以利用RV字段、MCS字段和FDRA字段中的一个或多个的特定值来表示NACK。作为一个非限制性示例，RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0表示NACK。具体地，如图4和图5所示，DCI格式1_1和DCI格式1_2包括DCI格式的标识、载波指示、RV字段、MCS字段、FDRA字段和PUCCH资源指示。在RV字段的值全部为1、MCS字段的值全部为1、FDRA字段的值全部为0的情况下，表示NACK信息。此外，电子设备600还可以利用PUCCH资源指示字段来指示未解码成功的PUCCH。
如上所述，根据本公开的实施例，在用户设备利用PUCCH来传输波束质量信息，并且电子设备600只反馈NACK而不反馈ACK的情况下，电子设备600可以利用通过重用DCI格式1来承载反馈信息。
根据本公开的实施例，在用户设备通过PUSCH发送波束质量信息的情况下，电子设备600可以利用DCI格式0中的NDI字段的内容指示反馈信息。例如，电子设备600可以利用DCI格式0_0或DCI格式0_1中的上行调度准许中的NDI字段的内容来表示ACK或者NACK。在电子设备600成功接收到波束质量信息的情况下，可以将NDI字段的值设置为1；在电子设备600没有成功接收到波束质量信息的情况下，可以将NDI字段的值设置为0。进一步，电子设备600可以根据HARQ进程的标识信息(HARQ process ID)来确定与发送的波束质量信息相对应的NDI。
如上所述，根据本公开的实施例，在用户设备利用PUSCH来传输波束质量信息的情况下，电子设备600可以通过DCI格式0中的HARQ进程的标识信息和NDI字段来承载反馈信息。
如上所述，本公开认为电子设备600需要对用户设备发送的波束质量信息进行反馈。进一步，本公开设计了电子设备600发送反馈信息的细节，从而提高波束质量信息的可靠性。
根据本公开的实施例，如图6所示，电子设备600还可以包括面板确定单元640，用于为用户设备确定用于上行传输的多个面板。进一步，生成单元630可以生成上行调度信息，并且电子设备600可以通过通信单元610将上行调度信息发送至用户设备。这里，电子设备600可以通过DCI格式0来发送上行调度信息。
根据本公开的实施例，上行调度信息可以包括多个SRI以用于指示为用户设备调度的多个面板。也就是说，电子设备600可以确定需要调度的多个面板上的多个波束，由于SRI与上行波束具有一一对应的关系，因此可以分别用多个SRI指示多个波束，从而指示多个面板。
根据本公开的实施例，上行调度信息可以包括一个SRI以用于指示为用户设备调度的多个面板上的多个波束。例如，可以在用户设备与电子设备600之间预设波束组合与SRI的映射关系。也就是说，可以将不同的面板上的波束的各种组合都列举出来，每个组合与一个SRI具有映射关系。这样一来，电子设备600可以确定与调度的波束组合相对应的SRI，从而将该SRI包括在上行调度信息中。
根据本公开的实施例，如图6所示，电子设备600还可以包括预编码矩阵确定单元650，用于为调度的多个面板的各个端口确定预编码矩阵。
根据本公开的实施例，在电子设备600调度的多个面板之间相干的情况下，这多个面板可以使用相同的预编码矩阵。因此，预编码矩阵确定单元650可以确定一个预编码矩阵以用作多个面板的预编码矩阵，生成单元630可以用一个TPMI指示该预编码矩阵，并将该TPMI包括在上行调度信息中。
根据本公开的实施例，在电子设备600调度的多个面板之间非相干的情况下，多个面板使用不同的预编码矩阵，预编码矩阵确定单元650还可以根据调度的各个面板的面板内相干类型确定各个面板的预编码矩阵的数目。也就是说，在面板内相干类型为完全相干的情况下，该面板的所有端口使用相同的预编码矩阵，即该面板需要的预编码矩阵的数目为1；在面板内相干类型为非相干的情况下，该面板的所有端口使用不同的预编码矩阵，即该面板需要的预编码矩阵的数目与端口的数目相同；在面板内相干类型为部分相干的情况下，该面板的相干的端口使用相同的预编码矩阵，不相干的端口使用不同的预编码矩阵。进一步，在预编码矩阵确定单元650确定了各个面板的预编码矩阵的数目之后，生成单元630可以用相应数目的TPMI指示多个预编码矩阵，并将这多个TPMI包括在上行调度信息中。
这里，电子设备600可以通过波束质量信息中的面板间相干类型来确定各个面板之间的相干关系，并且通过面板信息中的面板内相干类型类确定各个面板的端口之间的相干关系，从而确定需要发送的TPMI的数目。
如上所述，本公开对电子设备600同时调度用户设备的多个面板的细节进行了设计，从而使得电子设备600可以利用上行调度信息同时调度多个面板，并为多个面板配置预编码矩阵。
由此可见，根据本公开的实施例，不管用户能力值集合是否相同，用户设备都可以将该面板上报至电子设备600，即电子设备600在调度多面板时没有任何限制。此外，本公开定义了用户能力值集合中的两个用户能力值：SRS端口的数目和面板内相干类型。进一步，本公开认为电子设备600需要对用户设备发送的波束质量信息进行反馈，并且设计了电子设备600发送反馈信息的细节，从而提高波束质量信息的可靠性。此外，本公开对电子设备600同时调度用户设备的多个面板的细节进行了设计，从而使得电子设备600可以利用上行调度信息同时调度多个面板，并为多个面板配置预编码矩阵。综上，本公开优化了用户设备的多面板上行传输过程。
