具体实施方式
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。
应理解，本申请实施例的技术方案可以应用于各种通信系统，例如：全球移动通讯(Global System of Mobile communication，GSM)系统、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolved，LTE)系统、LTE频分双工(Frequency Division Duplex，FDD)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、全球互联微波接入(Worldwide Interoperability for Microwave Access，WiMAX)通信系统、新无线(New Radio，NR)或未来的5G系统等。
特别地，本申请实施例的技术方案可以应用于各种基于非正交多址接入技术的通信系统，例如稀疏码多址接入(Sparse Code Multiple Access，SCMA)系统、低密度签名(Low Density Signature，LDS)系统等，当然SCMA系统和LDS系统在通信领域也可以被称为其他名称；进一步地，本申请实施例的技术方案可以应用于采用非正交多址接入技术的多载波传输系统，例如采用非正交多址接入技术正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)、滤波器组多载波(Filter Bank Multi-Carrier，FBMC)、通用频分复用(Generalized Frequency Division Multiplexing，GFDM)、滤波正交频分复用(Filtered-OFDM，F-OFDM)系统等。
本申请实施例中的终端设备可以指用户设备(User Equipment，UE)、接入终端、用户单元、用户站、移动站、移动台、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。接入终端可以是蜂窝电话、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)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，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，PLMN)中的终端设备等，本申请实施例并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
图1是本申请实施例一个应用场景的示意图。图1中的通信系统可以包括终端设备10和网络设备20。网络设备20用于为终端设备10提供通信服务并接入核心网，终端设备10通过搜索网络设备20发送的同步信号、广播信号等而接入网络，从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备10与网络设备20之间的蜂窝链路进行的上/下行传输。
从网络侧来看，当某个小区有下行数据需要发送时，就有可能要求终端发送非周期性信道状态信息(Channel State Information，CSI)上报。在LTE系统中，非周期性CSI是通过物理上行共享信道(Physical Uplink Shared Channel，PUSCH)上报的；在NR系统中，非周期性CSI可以通过PUSCH上报，也可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)上报的，当采用PUCCH上报时，网络侧如何对PUCCH进行配置是需要解决的问题。
应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。本文中术语“和/或”，仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。另外，本文中字符“/”，一般表示前后关联对象是一种“或”的关系。
图2示出了本申请实施例的传输PUCCH的方法100的示意性框图。如图2所示，该方法100包括以下部分或全部内容：
S110，终端设备接收网络设备发送的下行控制信息DCI，该DCI包括CSI的触发信息和承载该非周期性CSI的PUCCH的配置信息。
S120，在该触发信息触发该终端设备上报该非周期CSI的情况下，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI。
需要说明的是，在本申请实施例中的触发信息，不仅可以是对终端设备上报非周期CSI的触发，也可以是对相应的CSI的上报配置的触发，举例来说，网络设备可以提前为CSI配置多种上报配置，该触发信息可以是触发该多种上报配置中的一种。所谓上报配置可以是网络设备针对非周期CSI的上报配置的各种信息。也就是说，该触发信息可以用于通知终端设备是否需要上报非周期CSI和/或在需要上报的情况下，如何上报该非周期CSI。例如，该触发信息可以是某个下行控制信息(Downlink Control Information，DCI)中的某两个比特位，其中，一个比特位可以用来指示是否需要终端设备上报非周期CSI，另一个比特位可以用来指示如何上报CSI。另外，该DCI中还可以携带一个关于承载该非周期CSI的上行信道的配置信息。例如，该上行信道的时频资源等。若该DCI携带的是PUCCH的配置信息，就可以说明网络设备指示终端设备使用PUCCH来传输非周期CSI，进而终端设备可以根据该配置信息来配置承载非周期CSI的PUCCH；若该DCI携带的是PUSCH的配置信息，就可以说明网络设备指示终端设备使用PUSCH来传输非周期CSI，进而终端设备可以根据该配置信息来配置承载CSI的PUSCH。
因此，本申请实施例的传输PUCCH的方法，网络侧可以动态调整承载非周期CSI上报的PUCCH的配置信息，有利于提高PUCCH的传输性能。
应理解，上述触发信息和配置信息是独立的两个信息域，该触发信息和配置信息也可以是一个信息域，例如，终端设备只要接收到该DCI中携带的是PUCCH的配置信息，那么就默认需要使用PUCCH进行非周期CSI的上报。本申请实施例对此不构成限定。
可选地，网络设备也可以给终端设备发送一个指示信息，指示承载非周期CSI的上行信道。例如，该指示信息可以是一个比特位，网络设备可以与终端设备约定，该比特位为“0”则为PUCCH，该比特位为“1”，则为PUSCH。如果该指示信息指示采用PUCCH承载非周期CSI，则上述DCI中携带的配置信息就是用于配置PUCCH的，如果该指示信息指示采用PUSCH承载非周期CSI，则上述DCI中携带的配置信息就是用于配置PUSCH的。该指示信息可以同上述非周期CSI的触发信息一样，承载于同一个DCI信令中，或者该指示信息可以与上述触发信息占用相同的信息域；该指示信息也可以承载于非周期CSI的上报配置中，举例来说，网络设备 可以将承载非周期CSI的上行信道与非周期CSI的上报配置对应起来，换句话说，每一种非周期CSI的上报配置中都携带与某一种上行信道对应的指示信息。关于非周期CSI的上报配置可以是由网络设备预先通知终端设备的，例如，可以通过无线资源控制(Radio Resource Control，RRC)信令半静态配置。
可选地，该DCI可以是一个调度信息，例如，可以是一个用于调度上行传输的信息，本申请实施例不限于此。
可选地，在本申请实施例中，该PUCCH的配置信息包括以下信息中的至少一种信息：该PUCCH的资源配置信息、该PUCCH的发送功率控制TPC命令、与该PUCCH对应的参考信号资源配置、该PUCCH的准共址QCL指示信息和该PUCCH的解调参考信号DMRS配置。
应理解，承载非周期CSI的配置信息包括但不限于上述各种信息。任何只要能够用来配置PUCCH的信息都在本申请技术方案的保护范围之内。
下面将一一结合上述举例的各种配置信息，详细介绍本申请实施例的技术方案。
可选地，在本申请实施例中，该PUCCH的配置信息包括该PUCCH的资源配置信息，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI，包括：该终端设备根据该PUCCH的资源配置信息，确定该PUCCH所占用的时频资源和/或该PUCCH所占用的PUCCH资源；该终端设备在该时频资源和/或该PUCCH资源上传输该非周期性CSI。
这里有两个术语需要说明，PUCCH的时频资源是一种物理上的概念，而PUCCH资源则是一种逻辑上的概念，这两者之间具有映射关系。通常所谓的时频资源可以是PUCCH占用的带宽、PUCCH占用的正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号数和PUCCH所占用的OFDM符号中的任何一项，该时频资源还可以是PUCCH所占的子载波数目等。
可选地，在本申请实施例中，该PUCCH的配置信息包括该PUCCH的发送功率控制TPC命令，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI，包括：该终端设备根据该TPC命令，确定该PUCCH的发送功率；该终端设备采用该发送功率在该PUCCH上传输该非周期CSI。
功率控制是常见的提高通信质量的一种方法。发送功率控制的基本原理 可以是接收方可以根据接收到信号的信干比与信干比目标值比较，然后向发送方返回一个发送功率控制(Transmitted Power Control，TPC)命令，通过高层给定的功率控制算法得到是增加发射功率还是减小发射功率的。具体地，终端设备可以根据该TPC命令，确定该PUCCH的闭环功率调整值；然后根据该闭环功率调整值调整发送功率，进而根据调整后的发送功率在PUCCH上传输非周期CSI。通常，所谓的闭环功率调整值可以是通过累加模式(即在现有闭环功率调整值的基础上累加TPC命令指示的值)，也可以是采用绝对值模式(即直接将该TPC命令指示的值作为闭环功率调整值)。
可选地，在本申请实施例中，该PUCCH的配置信息包括该PUCCH的参考信号资源配置，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI，包括：该终端设备根据该参考信号资源配置，确定该PUCCH的发送波束；该终端设备采用该发送波束进行该PUCCH的传输。
具体地，终端设备可以将在该参考信号资源配置所指示的参考信号资源上传输参考信号所采用的发送波束或接收波束确定为该PUCCH的发送波束。该参考信号资源配置可以是用于指示传输上行参考信号的资源，例如探测参考信号(Sounding Reference Signal，SRS)资源；也可以用于指示下行参考信号资源，例如，信道状态信息参考信号(Channel State Information-Reference Signal，CSI-RS)资源或者同步信号块(Synchronization Signal Block，SSB)。进一步地，该参考信号资源配置指示上行参考信号资源还是下行参考信号资源可以根据终端侧的波束对应性是否可用来确定。如果终端侧的波束对应性可用，则该参考信号资源配置可以指示下行参考信号资源；如果终端侧的波束对应性不可用，则该参考信号资源配置只能指示上行参考信号资源。终端设备可以将波束对应性是否可用的信息预先上报给网络设备。
可选地，在本申请实施例中，该PUCCH的配置信息包括该PUCCH的解调参考信号DMRS配置，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI，包括：该终端设备根据该DMRS配置，确定用于解调该PUCCH的DMRS；该终端设备根据该DMRS在该PUCCH上传输该非周期CSI。
具体地，该解调参考信号(Demodulation Reference Signal，DMRS)配置可以是指示该DMRS的序列和/或该DMRS所占用的资源。
可选地，在本申请实施例中，该PUCCH的配置信息包括该PUCCH的准共址QCL指示信息，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI，包括：该终端设备根据该QCL指示信息，确定该PUCCH的发送波束；该终端设备采用该发送波束在该PUCCH上传输该非周期CSI。
具体地，终端设备可以根据该准共址(Quasi-Co-location，QCL)指示信息，确定与该PUCCH准共址的上行信号，然后再根据传输该上行信号所用的波束，进一步确定该PUCCH的发送波束，例如，可以直接将传输该上行信号所用得波束作为传输该PUCCH的波束。应理解，该上行信号与该PUCCH可以只针对空间接收参数准共址。
可选地，在本申请实施例中，该非周期CSI包括以下信息中的至少一种信息：信道状态信息参考信号CSI-RS的资源索引、秩指示(rank indication，RI)、预编码信息和信道质量指示(Channel Quality Indicator，CQI)。
图3示出了本申请实施例的传输PUCCH的方法200的示意性框图。如图3所示，该方法200包括以下部分内容或全部内容：
S210，网络设备向终端设备发送下行控制信息DCI，该DCI包括非周期信道状态信息CSI的触发信息和承载该非周期性CSI的PUCCH的配置信息，以便于在该触发信息触发该终端设备上报该非周期CSI的情况下，该终端设备根据该PUCCH的配置信息在该PUCCH上传输该非周期CSI。
因此，本申请实施例的传输PUCCH的方法，网络侧可以动态调整承载非周期CSI上报的PUCCH的配置信息，有利于提高PUCCH的传输性能。
可选地，在本申请实施例中，该PUCCH的配置信息包括以下信息中的至少一种信息：该PUCCH的资源配置信息、该PUCCH的发送功率控制TPC命令、该PUCCH的参考信号资源配置、该PUCCH的准共址QCL指示信息和该PUCCH的解调参考信号DMRS配置。
