Abstract

Description

通信方法及装置 技术领域
本申请实施例涉及通信技术领域，尤其涉及一种通信方法及装置。
背景技术
为了提高数据传输的可靠性，终端设备可以接收来自网络设备的参考信号，如信道状态信息参考信号(channel state information-reference signal，CSI-RS)，利用该CSI-RS信号估计更准确的信道状态信息(channel state information,CSI)，并发送给网络设备，以便网络设备利用该信道状态信息向终端设备发送下行信息。
一般地，CSI的发送方式包括：周期性发送CSI(periodic CSI，P-CSI)，半持久性发送CSI(semipersistent CSI，SP-CSI)和非周期性发送CSI(aperiodic CSI，A-CSI)。对于A-CSI，网络设备通过下行控制信息(downlink control information，DCI)触发终端设备接收来自网络设备的CSI-RS并利用该CSI-RS测量信道和干扰，终端设备得到CSI后发送给网络设备。对于P-CSI和被配置激活后的SP-CSI，终端设备会周期性地接收CSI-RS，并根据CSI-RS测量信道和干扰，周期性地向网络设备发送CSI。然而，采用以上列举的发送方式会导致终端设备频繁发送不必要的CSI，信令开销大。
发明内容
本申请提供一种通信方法及装置，用于降低终端设备发送信道状态信息或上行参考信号的信令开销。
第一方面，提供一种通信方法。该通信方法包括：确定第一反馈信息集合，当第一反馈信息集合满足第一条件时，向网络设备发送第一信道状态信息或第一上行参考信号。其中，第一反馈信息集合包括至少一个反馈信息，反馈信息为否认应答(negative acknowledgement，NACK)或确认应答(acknowledgement，ACK)。
基于第一方面所述的通信方法，终端设备将确定第一反馈信息集合，并根据第一反馈信息集合确定是否向网络设备发送第一信道状态信息或第一上行参考信号，当第一反馈信息集合满足第一条件时，向网络设备发送第一信道状态信息或第一上行参考信号。如此，终端设备可以通过第一反馈信息集合确定是否发送信道状态信息或上行参考信号，无需频繁发送信道状态信息或上行参考信号，从而节省信令开销。此外，可以避免由网络设备触发信道的测量和信道状态信息的发送，可以缩短网络设备获得信道状态信息或上行参考信号的时延，从而满足低时延业务的需求。
在一种可能的实现方式中，第一条件可以为第一反馈信息集合中NACK的特征满足的条件。
在一种可能的实现方式中，NACK的特征可以包括：NACK在第一反馈信息集合的位置、和/或NACK的数量。
在一种可能的实现方式中，第一条件可以包括如下一项或多项：第一反馈信息集合中的NACK的数量与ACK的数量的比值大于或等于第一阈值、第一反馈信息集合中的NACK的数量大于或等于第二阈值、第一反馈信息集合中的连续的NACK的数量大于或等于第三阈值、和第一反馈信息集合中的NACK的数量与总的反馈信息的数量的比值大于或等于第四阈值。可选地，第一阈值、第二阈值、第三阈值和第四阈值可以是预设置的或预配置的。
在一种可能的实现方式中，第一条件可以包括：第一反馈信息集合包括至少一个高优先级的反馈信息。可选地，高优先级的反馈信息对应极高可靠极低时延场景(ultra-reliable and low-latency communications，URLLC)业务，高优先级的反馈信息可以包括高优先级的NACK或高优先级的ACK。
在一种可能的实现方式中，第一条件可以包括：第一反馈信息集合包括至少一个低优先级的反馈信息。可选地，低优先级的反馈信息可以对应增强移动宽带(enhanced mobile broadband，eMBB)业务，低优先级的反馈信息可以包括低优先级的NACK或低优先级的ACK。
在一种可能的实现方式中，第一信道状态信息或第一上行参考信号可以是根据第一配置信息配置的，第一配置信息对应的第一反馈信息集合可以包括至少一个高优先级的反馈信息。如此，终端设备可以根据第一反馈信息集合中包括的反馈信息的不同优先级，向网络设备发送不同的第一信道状态信息或第一上行参考信号，以满足不同业务的多样化需求。
在一种可能的实现方式中，第一信道状态信息或第一上行参考信号可以是根据第二配置信息配置的，第二配置信息对应的第一反馈信息集合可以包括至少一个低优先级的反馈信息。如此，终端设备可以根据第一反馈信息集合中包括的反馈信息的不同优先级，向网络设备发送不同的第一信道状态信息或第一上行参考信号，以满足不同业务的多样化需求。
在一种可能的实现方式中，第一方面提供的通信方法，还可以包括：当未向网络设备发送第一反馈信息集合时，静默第一信道状态信息或第一上行参考信号的发送。也就是说，如果终端设备未向网络设备发送第一反馈信息集合、或者第一反馈信息集合的发送被取消，那么可以取消第一信道状态信息或第一上行参考信号的发送，或者不发送第一信道状态信息或第一上行参考信号，以节省信令开销。
在一种可能的实现方式中，第一反馈信息集合可以包括至少一个高优先级的反馈信息，第一方面提供的通信方法，还可以包括：确定第二反馈信息集合。其中，第二反馈信息集合可以包括至少一个低优先级的反馈信息，第二反馈信息集合与第一反馈信息集合是在同一信道中传输的。可选的，第二反馈信息集合对应的资源与第一反馈信息集合对应的资源可以部分或全部重叠。
在一种可能的实现方式中，第一方面提供的通信方法，还可以包括：当第二反馈信息集合满足第二条件时，向网络设备发送第二信道状态信息或第二上行参考信号。
可选地，第二条件为第二反馈信息集合中NACK的特征满足的条件。NACK的特征可以包括：NACK在第二反馈信息集合中的位置、和/或NACK的数量。
可选地，第二条件包括如下一项或多项：第二反馈信息集合中的NACK的数量与ACK的数量的比值大于或等于第五阈值、第二反馈信息集合中的NACK的数量大于或等于第六阈值、第二反馈信息集合中的连续的NACK的数量大于或等于第七阈值、和第二反馈信息集合中的NACK的数量与总的反馈信息的数量的比值大于或等于第八阈值。
在另一种可能的实现方式中，第一方面提供的通信方法，还可以包括：当第一反馈信息集合满足第一条件且第二反馈信息集合满足第二条件时，静默第二信道状态信息或第二上行参考信号的发送。也就是说，当第一反馈信息集合满足第一条件且第二反馈信息集合满足第二条件时，可以向网络设备发送第一信道状态信息或第一上行参考信号，并取消第二信道状态信息或第二上行参考信号的发送，或者不发送第二信道状态信息或第二上行参考信号，以节省信令开销。
在另一种可能的实现方式中，第一方面提供的通信方法，还可以包括：当第一反馈信息集合不满足第一条件且第二反馈信息集合满足第二条件时，向网络设备发送第二信道状态信息或第二上行参考信号。如此，可以保证数据传输的可靠性。
可选地，NACK为对下行信息解码失败后获得的NACK。也就是说，在判断第一反馈信息集合是否满足第一条件时，可以只将对下行信息解码失败后获得的NACK作为有效NACK。
如此，采用只将对下行信息解码失败后获得的NACK作为有效NACK的第一条件，与采用将对下行信息解码失败后获得的NACK和填充的NACK均作为有效NACK的第一条件相比，可以进一步降低发送第一信道状态信息或第一上行参考信号的不必要的开销。
可选地，第一反馈信息集合包括至少两个反馈信息。也就是说，终端设备可以针对多个反馈信息判断是否发送第一信道状态信息或第一上行参考信息，可以减少发送第一信道状态信息或第一上行参考信息的次数，从而节省终端设备与网络设备时间的信令开销。
第二方面，提供一种通信方法。该通信方法包括：接收来自终端设备的第一反馈信息集合，接收来自终端设备的第一信道状态信息或第一上行参考信号。其中，第一反馈信息集合包括至少一个反馈信息，反馈信息为否认应答NACK或确认应答ACK，第一反馈信息集合是满足第一条件的。

如图1所示，该通信系统包括终端设备和网络设备。
其中，上述终端设备为接入上述通信系统，且具有无线收发功能的终端或可设置于该终端的芯片或芯片系统。该终端设备也可以称为用户设备(user equipment，UE)、用户装置、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。本申请的实施例中的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、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端、车载终端、或具有终端功能的路侧单元(Road Side Unit，RSU)等。其中，车载终端可以是车载模块、车载模组、车载部件、车载芯片或者车载单元。上述网络设备为位于上述通信系统的网络侧，且具有无线收发功能的设备或可设置于该设备的芯片或芯片系统。该网络设备包括但不限于：无线保真(wireless fidelity，WiFi)系统中的接入点(access point，AP)(如家庭网关、路由器、服务器、交换机、网桥等)、基站、演进型节点B(evolved Node B，eNB)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(baseband unit，BBU)、无线中继节点、无线回传节点、或传输点(transmission and reception point，TRP或者transmission point，TP)等。该网络设备还可以为5G，如，新空口(new radio，NR)系统中的gNB、传输点(TRP或TP)、5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者可以为构成gNB或传输点的网络节点等，如基带单元(BBU)、集中式单元(central unit,CU)、分布式单元(distributed unit，DU)、或具有基站功能的RSU等。CU可以包括控制面(central unit-control plane，CU-CP)和用户面(central unit-user plane，CU-UP)。该网络设备还可以为包括CU和分布式单元DU的设备。

应理解，图1仅为便于理解而示例的简化示意图，该通信系统中还可以包括其他网络设备，和/或，其他终端设备，图1中未予以画出。
为了便于理解，下面对本申请实施例中涉及的参考信号的配置信息进行阐述。
以参考信号为CSI-RS为例，配置信息可以包括配置的信息元素(information element，IE)，如CSI资源配置(CSI-ResourceConfig)和CSI上报配置(CSI-ReportConfig)。
其中，上述CSI资源配置，可用于配置CSI测量的资源相关的信息。示例性地，CSI资源配置可以包括如下一项或多项：CSI资源配置标识(CSI-ResourceConfigId)、资源的类型(ResourceType)配置信息、CSI资源集合队列(CSI-RS-ResourceSetList)配置信息。
具体地，CSI资源配置标识为CSI资源配置的标识，该CSI资源配置标识可与CSI上报配置相关联。例如，CSI资源配置标识3与上报配置标识为1的CSI上报配置相关联，则可得知，CSI资源配置标识为3的配置信息对应上报配置标识为1的CSI上报配置信息。
资源的类型(ResourceType)配置信息，可以包括周期性资源、半持久性资源和非周期性资源。按CSI-RS的资源的功能可以将CSI-RS的资源分为:用于信道测量的非零功率CSI-RS(non-zero power CSI-RS，NZP-CSI-RS)、用于干扰测量的零功率CSI-RS(zero power CSI-RS，ZP-CSI-RS)和用于干扰测量的NZP-CSI-RS。其中，ZP-CSI-RS也可以称为信道状态信息干扰测量CSI-IM(channel state information interference measurement)。对于ZP-CSI-RS资源，网络设备在ZP-CSI-RS资源上不发送任何信息，终端设备在该资源上进行检测，检测 到的信息即为干扰。对于NZP-CSI-RS资源，网络设备在该资源上发送已知序列，终端设备可以通过已知序列得到CSI和/或干扰。
CSI资源集合队列配置信息，可用于配置资源集合的队列，该被配置的资源集合的队列可以包括NZP-CSI-RS的资源集合和/或CSI-IM的资源集合。其中，可以通过资源集合的标识关联到资源集合的配置，如可以通过NZP-CSI-RS资源集合标识(NZP-CSI-RS-ResourceSetId)关联到NZP-CSI-RS资源集合(NZP-CSI-RS-ResourceSet)配置信息，可以通过CSI-IM资源集合标识(CSI-IM-ResourceSetId)关联到CSI-IM资源集合(CSI-IM-ResourceSet)配置信息。
示例性地，NZP-CSI-RS资源集合配置信息，可用于配置信道测量的资源的集合，所述资源的集合可以包括至少一个NZP-CSI-RS的资源。其中，可以通过资源的标识关联到资源的配置，如可以通过NZP-CSI-RS资源标识(NZP-CSI-RS-ResourceId)关联到NZP-CSI-RS资源(NZP-CSI-RS-Resources)配置信息。NZP-CSI-RS资源配置信息，是可用于配置与NZP-CSI-RS的资源相关的信息。示例性地，终端设备可以根据NZP-CSI-RS的资源测量信道信息，并反馈CSI。当一个NZP-CSI-RS的资源集合中包括多个NZP-CSI-RS的资源时，终端设备具体反馈的是哪个NZP-CSI-RS的资源上测量得到的CSI，可以通过终端设备反馈的CSI-RS的资源指示信息(CSI-RS resource indicator，CRI)指示。例如CRI＝0，可以表示终端设备反馈的CSI是通过资源Id＝0的资源上测量得到的信道信息。
示例性地，CSI-IM资源集合配置信息，可用于配置测量干扰的资源的集合，与上述NZP-CSI-RS资源集合配置信息类似，本申请实施例不再赘述。CSI-IM资源配置信息，可用于配置CSI-IM的资源相关的信息，可通过CSI-IM资源标识关联到CSI-IM资源配置信息。
其中，上述CSI上报配置，可用于配置与CSI上报有关的参数，例如上报CSI的类型、上报的测量指标等。示例性地，CSI上报配置可以包括但不限于如下一项或多项：上报配置标识(ReportConfigId)、信道测量的资源(ResourcesForChannel Measurement)配置信息、干扰测量的CSI-IM资源(CSI-IM-RessourcesForInterference)配置信息、干扰测量的NZP-CSI-RS资源(NZP-CSI-RS-ResourcesForInterference)配置信息、上报配置类型(ReportConfigType)、上报的量(reportQuantity)、以及宽带反馈或窄带反馈。
具体地，上述上报配置标识为CSI上报配置的标识。信道测量的资源配置信息，可用于配置信道测量的CSI-RS的资源,可以通过CSI资源配置标识(CSI-ResourceConfigId)关联到CSI资源配置。干扰测量的CSI-IM资源配置信息，可用于配置干扰测量的CSI-RS的资源，可以通过CSI资源配置标识(CSI-ResourceConfigId)关联到CSI资源配置。干扰测量的NZP-CSI-RS资源配置信息，可用于配置干扰测量的NZP-CSI-RS的资源，可以通过CSI资源配置标识(CSI-ResourceConfigId)关联到CSI资源配置。
上报配置类型，可表示CSI的发送方式，可以包括P-CSI、SP-CSI和A-CSI。其中，P-CSI可以是网络设备通过无线资源控制(radio resource control，RRC)消息为终端设备配置的，不需要网络设备触发。SP-CSI可以是网络设备通过媒体接入控制控制单元(medium access control control element，MAC CE)或者DCI触发的，终端设备在触发之后是周期性发送CSI。通过MAC CE触发的SP-CSI在物理上行控制信道(physical uplink control channel，PUCCH)上发送CSI，通过DCI触发的SP-CSI在物理上行共享信道(physical downlink shared channel，PUSCH)上发送CSI。A-CSI是网络设备通过DCI触发的，触发后在指定的时隙内指定的PUSCH上只上报一次。
上报的量可以包括CRI、秩指示(rank indicator，RI)、预编码矩阵指示(precoding matrix indicator，PMI)、和/或信道质量指示(channel quantity indicator,CQI)等。网络设备可以通过向终端设备发送不同的配置信息，使终端设备上报其中的全部或者部分。宽带反馈可以表示在整个上报带宽内只反馈一个值。窄带反馈可以表示对每个子带分别反馈。
需要说明的是，在NR系统中，上行参考信号可以用于测量上行信道。在时分双工(time division duplex，TDD)系统中，可以利用上下行信道的互异性，获取下行信道状态信息。与利用CSI-RS信号估计CSI类似，可以利用上行参考信号估计CSI，上行参考信号可以是探测参考信号(sounding reference signal，SRS)，关于上行参考信号SRS的配置信息与参考信号CSI-RS的配置信息类似，本申请实施例不再赘述。
本申请实施例提供的通信方法适用于终端设备向网络设备发送上行信息的场景以及终端设备接收来自网络设备的下行信息的场景。图2为本申请实施例提供的通信方法的流程示意图一，主要以终端设备接收来自网络设备的下行信息的场景为例进行阐述。该通信方法可以适用于图1所示的终端设备与网络设备之间的通信。
如图2所示，该通信方法包括如下步骤：
S201，终端设备确定第一反馈信息集合。
示例性地，第一反馈信息集合包括至少一个反馈信息，反馈信息为NACK或ACK。具体地，若终端设备对来自网络设备的下行信息解码成功或者成功接收所述下行信息，终端设备可以向网络设备发送ACK；若终端设备对来自网络设备的下行信息解码失败或者接收所述下行信息失败，终端设备可以向网络设备发送NACK，第一反馈信息集合中可以包括一个或多个ACK和/或一个或多个NACK。
可选地，第一反馈信息集合包括至少一个NACK和/或至少一个ACK组成的码本序列。例如，第一反馈信息集合可以为NAAAANA，其中“N”表示NACK，“A”表示ACK。
示例性的，第一反馈信息集合包括至少一个信息比特，一个信息比特可承载一个反馈信息。例如，当信息比特为0时，表示反馈信息为NACK，信息比特为1时，表示反馈信息为ACK。又例如，当信息比特为0时，表示反馈信息为ACK，信息比特为1时，表示反馈信息为NACK。
为了便于阅读，本申请实施例以终端设备对下行信息解码失败，则解码结果为NACK，将对应的反馈信息置为“N”，对下行信息解码正确，则解码结果为ACK，将对应的反馈信息置为“A”为例进行阐述。
可选地，第一反馈信息集合中包括填充(full)的NACK和/或对下行信息解码失败后得到的NACK。
下面对填充的NACK进行阐述。以下行信息为例，每个可能的下行信息均有一个对应的反馈信息。所述可能的下行信息的具体含义为：在一个资源上，网络设备可以给终端设备发送下行信息，但是，网络设备也可以选择在该资源上不发送下行信息。
若终端设备接收到了下行信息，则反馈信息具体为NACK或者ACK根据下行信息的解码确定。例如，如果接收到下行信息且解码正确，则反馈信息为ACK，反之，反馈信息为NACK。
若终端设备未接收到下行信息，则将该未收到的下行信息对应的反馈信息置为NACK。该NACK即为填充的NACK，表示终端设备并没有真正的接收到与该反馈信息对应的下行信息。示例性的，终端设备没有接收到下行信息的原因可以是网络设备没有给终端设备发送下 行信息，或者，网络设备给终端设备发送了下行信息，但由于终端设备没有收到该下行信息的调度信息，导致没有接收到下行信息。
图3为本申请实施例提供的第一反馈信息集合示意图。
以时间单元为时隙为例，图3中包括编号为0-9的时隙，假设编号为3和编号8的时隙位置为上行时隙，其它时隙位置为下行时隙，编号为1、2、4、5、7的下行时隙与编号为8的上行时隙对应。具体地，在编号为1的下行时隙发送的下行信息对应的反馈信息，在编号为8的上行时隙发送给网络设备。类似地，在编号为2、4、5、7的下行时隙发送的下行信息分别对应的反馈信息，在编号为8的上行时隙发送给网络设备。因此，在编号为8的上行时隙中存在多个反馈信息，所述多个反馈信息分别与在编号为1、2、4、5、7的下行时隙中所有可能的下行信息相对应。假设编号为1、2、4、5、7的时隙中分别只有一个可能的下行信息，则在编号为8的上行时隙中存在5个反馈信息，这5个反馈信息分别对应在编号为1、2、4、5、7的下行时隙中可能的下行信息。
结合图3，假设编号为1、2的下行时隙为被调度的下行时隙，其它下行时隙为未被调度的下行时隙，网络设备仅在编号为1、2的下行时隙发送下行信息，未在编号为4、5、7的下行时隙发送下行信息，终端设备接收这两个下行信息并解码，解码结果均为NACK，则第一反馈信息集合为NNNNN。其中，编号为1、2的下行时隙对应的NACK(即前两个“N”)是根据解码结果确定的，编号为4、5、7的下行时隙对应的NACK(即后三个“N”)是填充的NACK。
可选地，第一反馈信息集合包括至少两个反馈信息。示例性地，第一反馈信息集合可以包括一个NACK和一个ACK，或者包括两个NACK，或者包括两个ACK。
也就是说，终端设备可以基于多个反馈信息判断是否发送第一信道状态信息或第一上行参考信息，可以减少发送第一信道状态信息或第一上行参考信息的次数，从而节省终端设备与网络设备之间的信令开销。
示例性地，第一上行参考信息可以是SRS，在NR系统中，SRS可以用于测量上行信道，在时分双工(time division duplex，TDD)系统中，可以利用上下行信道的互异性，获取下行信道状态信息。
在一些实施方式中，本申请实施例提供的通信方法，还可以包括：网络设备向终端设备发送至少一个下行信息。相应的，终端设备接收来自网络设备的至少一个下行信息。
示例性的，下行信息可以是通过下行控制信息(downlink control information，DCI)调度的或半静态调度(semi-persistent scheduling，SPS)的，终端设备可以对接收的至少一个下行信息进行解码，获得上述至少一个反馈信息。
S202，当第一反馈信息集合满足第一条件时，终端设备向网络设备发送第一信道状态信息或第一上行参考信号。相应地，网络设备接收来自终端设备的第一信道状态信息或第一上行参考信号。
在一些实施方式中，第一条件可以为第一反馈信息集合中NACK的特征满足的条件。
可选地，NACK的特征可以包括：NACK在第一反馈信息集合中的位置、和/或NACK的数量。
可选地，第一条件可以是预定义的，第一条件具体包括哪个/些条件可以是协议预定义的。
以NACK的特征是NACK的数量为例，第一条件可以包括如下一项或多项条件：第一反馈信息集合中的NACK的数量与ACK的数量的比值大于或等于第一阈值、第一反馈信息集合中的NACK的数量大于或等于第二阈值、第一反馈信息集合中的连续的NACK的数量 大于或等于第三阈值、和第一反馈信息集合中的NACK的数量与总的反馈信息的数量的比值大于或等于第四阈值。
其中，第一阈值、第二阈值、第三阈值和第四阈值可以是预设置的或预配置的。示例性地，所述预设置的阈值可以是通过协议规定的。示例性地，所述预配置的阈值可以是网络设备确定并通知给终端设备的。
示例性地，以NACK的特征是NACK的数量为例，确定第一反馈信息集合是否满足第一条件的方式如下。
当第一条件包括一项条件时，若第一反馈信息集合满足该条件，则确认第一反馈信息集合满足第一条件，若第一反馈信息集合不满足该条件，则确认第一反馈信息集合不满足第一条件。
当第一条件包括多项条件时，确认第一反馈信息集合是否满足第一条件的方式可以包括：第一种方式，当第一反馈信息集合满足第一条件中的任一项条件时，即可确认第一反馈信息集合满足第一条件，当第一反馈信息集合不满足第一条件中的全部条件时，即可确认第一反馈信息集合不满足第一条件。或者，第二种方式，当第一反馈信息集合满足第一条件中的全部条件时，则确认第一反馈信息集合满足第一条件；当第一反馈信息集合不满足第一条件中的全部条件时，即可确认第一反馈信息集合不满足第一条件。
下面以NACK的特征是NACK的数量、第一条件包括一项条件为例进行阐述。
示例性地，假设第一阈值为1/3，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量与ACK的数量的比值等于1/2，大于第一阈值1/3，则该第一反馈信息集合满足第一条件，终端设备可以向网络设备发送第一信道状态信息或第一上行参考信号。
示例性地，假设第二阈值为3，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量等于2，小于第二阈值为3，则该第一反馈信息集合不满足第一条件，终端设备不向网络设备发送第一信道状态信息或第一上行参考信号。
示例性地，假设第二阈值为1，当第一反馈信息集合为NAAAAN，该第一反馈信息集合中NACK的数量为2，大于第二阈值，则该第一反馈信息集合满足第一条件，终端设备可以向网络设备发送第一信道状态信息或第一上行参考信号。
示例性地，当第一反馈信息集合为NAAAAN，该第一反馈信息集合连续的NACK的数量为1，当第一反馈信息集合为NNAAAN，该第一反馈信息集合连续的NACK的数量为2。假设第三阈值为2，第一反馈信息集合为NNAAAN。该第一反馈信息集合中连续的NACK的数量为2，等于第三阈值为2，则该第一反馈信息集合满足第一条件，终端设备可以向网络设备发送第一信道状态信息或第一上行参考信号。
示例性地，假设第四阈值为1/3，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量与总的反馈信息的数量的比值为2/6＝1/3，等于第四阈值1/3，则该第一反馈信息集合满足第一条件，终端设备可以向网络设备发送第一信道状态信息或第一上行参考信号。
下面以NACK的特征是NACK的数量、第一条件包括多项条件为例进行阐述。
以第一条件包括上述条件中的三项条件为例，假设第一条件包括第一反馈信息集合中的NACK的数量与ACK的数量的比值大于或等于第一阈值、第一反馈信息集合中的NACK的数量大于或等于第二阈值、和第一反馈信息集合中的连续的NACK的数量大于或等于第三阈值。
当第一条件包括上述条件中的多项条件时，采用第一种方式确认第一反馈信息集合是否满足第一条件的示例如下。
示例性地，假设第一阈值为1/3，第二阈值为3，第三阈值为2，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量与ACK的数量的比值等于1/2，大于第一阈值1/3，NACK的数量等于2，连续的NACK的数量为1，则该第一反馈信息集合满足第一条件。
示例性地，假设第一阈值为2/3，第二阈值为4，第三阈值为3，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量与ACK的数量的比值等于1/2，NACK的数量等于2，连续的NACK的数量为1，则该第一反馈信息集合不满足第一条件。
需要说明的是，当确定第一反馈信息集合满足第一条件中包括的一个条件时，可以不确定是否满足第一条件中包括的其它条件。例如，若已确定第一反馈信息集合中的NACK的数量大于或等于第二阈值，可以不再确定第一反馈信息集合中的连续的NACK的数量是否大于或等于第三阈值，以节省信号处理流程。
当第一条件包括上述条件中的多项条件时，采用第二种方式确认第一反馈信息集合是否满足第一条件的示例如下。
示例性地，假设第一阈值为1/3，第二阈值为3，第三阈值为2，第一反馈信息集合为NNAAAN。该第一反馈信息集合中NACK的数量与ACK的数量的比值等于1/2，大于第一阈值1/3；NACK的数量等于3，等于第二阈值3；连续的NACK的数量为2，等于第三阈值2，则该第一反馈信息集合满足第一条件。
示例性地，假设第一阈值为1/3，第二阈值为3，第三阈值为2，第一反馈信息集合为NAAAAN。该第一反馈信息集合中NACK的数量与ACK的数量的比值等于1/2，大于第一阈值1/3，NACK的数量等于2，连续的NACK的数量为1，则该第一反馈信息集合不满足第一条件。
可选地，当已确定第一反馈信息集合不满足第一条件中包括的任一项条件时，可以不确定是否满足第一条件中包括的其它条件。例如，若已确定第一反馈信息集合中的NACK的数量小于第二阈值，可以不再确定第一反馈信息集合中的连续的NACK的数量是否大于或等于第三阈值，以节省信号处理流程。
上述仅为本申请实施例提供的示例，本申请不再对第一反馈信息集合满足或不满足第一条件的示例进行一一列举。
可选地，第一条件中的NACK可以为有效NACK，NACK的数量可以为有效NACK的数量。
示例性地，第一条件可以包括如下一项或多项条件：第一反馈信息集合中的有效NACK的数量与ACK的数量的比值大于或等于第一阈值、第一反馈信息集合中的有效NACK的数量大于或等于第二阈值、第一反馈信息集合中的连续的有效NACK的数量大于或等于第三阈值、和第一反馈信息集合中的有效NACK的数量与总的反馈信息的数量的比值大于或等于第四阈值。
可选地，有效NACK包括对下行信息解码失败后获得的NACK和填充的NACK。第一反馈信息集合包括至少一个有效NACK。
或者，可选地，有效NACK为对下行信息解码失败后获得的NACK，第一条件中的NACK为对下行信息解码失败后获得的NACK。第一反馈信息集合包括至少一个有效NACK。
示例性地，在判断第一反馈信息集合是否满足第一条件时，可以只将对下行信息解码失败后获得的NACK作为有效NACK。
以第一条件包括第一反馈信息集合中的连续的NACK的数量大于或等于第三阈值为例，采用只将对下行信息解码失败后获得的NACK作为有效NACK的第一条件。假设第三阈值为2，第一反馈信息集合为NNNAAN，其中，第1个“N”和第2个“N”为对下行信息解码失败后获得的NACK，第3个“N”和第6个“N”为填充的NACK，则该第一反馈信息集合中的连续的NACK的数量为2(即第1个“N”和第2个“N”)，等于第三阈值2，该第一反馈信息集合满足第一条件。
以第一条件包括第一反馈信息集合中的NACK的数量大于或等于第二阈值为例，采用只将对下行信息解码失败后获得的NACK作为有效NACK的第一条件。假设第二阈值为3，第一反馈信息集合为NNAAAN，其中，第1个“N”和第2个“N”为填充的NACK，第6个“N”为对下行信息解码失败后获得的NACK，则该第一反馈信息集合中的NACK的数量为1(即第6个“N”)，小于第二阈值3，该第一反馈信息集合不满足第一条件，终端设备可以不向网络设备发送第一信道状态信息或第一上行参考信号，节省信令开销。
如此，在确定第一反馈信息集合是否满足第一条件时，只计算需要反馈对应的信道状态信息或上行参考信号的NACK(对下行信息解码失败后获得的NACK)，不计算其它不必要反馈信道状态信息或上行参考信号的NACK。填充的NACK，可能是因为网络设备没有给终端设备发送下行信息所导致的，并不能表示当前数据传输错误。因此，在判断是否满足第一条件时不考虑填充的NACK，可以进一步降低发送第一信道状态信息或第一上行参考信号的不必要的开销，而且不会导致太大的性能损失。
示例性地，在判断第一反馈信息集合是否满足第一条件时，可以将对下行信息解码失败后获得的NACK和填充的NACK均作为有效NACK。
假设第二阈值、第一反馈信息集合与上一示例相同(即第二阈值为3，第一反馈信息集合为NNAAAN，其中，第1个“N”和第2个“N”为填充的NACK，第6个“N”为对下行信息解码失败后获得的NACK)，不同的是采用将对下行信息解码失败后获得的NACK和填充的NACK均作为有效NACK的第一条件，则该第一反馈信息集合中的NACK的数量为3，等于第二阈值3，该第一反馈信息集合满足第一条件，从而终端设备向网络设备发送第一信道状态信息或第一上行参考信号。
本申请实施例中，“解码失败”和“解码错误”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。“解码成功”和“解码正确”有时可以混用，应当指出的是，在不强调其区别时，其所要表达的含义是一致的。

也就是说，不同的第一反馈信息集合可以根据不同的第一阈值、和/或不同的第二阈值、和/或不同的第三阈值、和/或不同的第四阈值确定是否满足第一条件。此外，不同第一反馈信息集合对应的第一条件也可以不同，例如，包括至少一个高优先级的反馈信息的第一反馈集合对应的第一条件为第一反馈信息集合中的NACK的数量与ACK的数量的比值大于或等于第一阈值，而包括至少一个低优先级的反馈信息的第一反馈集合对应的第一条件为第一反馈 信息集合中的NACK的数量大于或等于第二阈值。上述不同的第一反馈信息集合可指第一反馈信息集合中包括的反馈信息的优先级不同。
在一种可能的实施方式中，第一信道状态信息或第一上行参考信号可以是根据第一配置信息配置的，第一配置信息对应的第一反馈信息集合包括至少一个高优先级的反馈信息。
可选地，第一信道状态信息或第一上行参考信号与包括至少一个高优先级的反馈信息的第一反馈信息集合相对应。示例性地，网络设备可以根据包括至少一个高优先级的反馈信息的第一反馈信息集合确定第一配置信息，终端设备可以根据第一配置信息确定第一信道状态信息或第一上行参考信号，该第一信道状态信息或第一上行参考信号是由包括至少一个高优先级的反馈信息的第一反馈信息集合触发的。所述触发的含义可以是指：若第一反馈集合满足第一条件，终端设备会发送第一信道状态信息或第一上行参考信号。所述第一信道状态信息或第一上行参考信号是第一反馈集合触发的。
示例性地，可以通过如下方式确定第一配置信息对应的第一反馈信息集合包括至少一个高优先级的反馈信息。
例如，第一配置信息包括第一信息，第一信息与第一信道状态信息或第一上行参考信号相关联。
可选地，第一信息用于指示优先级。第一信息可指示高优先级或低优先级，例如，第一信息指示高优先级，则第一配置信息对应的第一反馈信息集合包括至少一个高优先级的反馈信息。包括至少一个高优先级的反馈信息的第一反馈信息集合触发的第一信道状态信息或第一上行参考信号是通过第一配置信息配置的。
或者，可选地，第一信息为CSI上报配置中的CQI表(CQI-Table)的指示信息，CQI表可用于计算CQI。例如，第一信息指示CSI上报配置中的CQI表对应的传输块错误概率(block error rate,BLER)为10^-5，则第一配置信息对应的第一反馈信息集合包括至少一个高优先级的反馈信息。
可选地，第一配置信息是第一信道状态信息或第一上行参考信号相关的配置信息。例如，第一配置信息可以包括上述CSI资源配置(CSI-ResourceConfig)和/或CSI上报配置(CSI-ReportConfig)。第一信道状态信息可以是根据第一配置信息配置得到的。
可选地，由包括至少一个高优先级的反馈信息的第一反馈信息集合触发的第一信道状态信息或第一上行参考信号是根据第一配置信息配置的，具体含义可以为，终端设备根据第一配置信息确定第一信道状态信息或第一上行参考信号。
以第一信道状态信息为例，终端设备根据第一配置信息确定第一信道状态信息包括的内容，包含CRI，RI，PMI，CQI的一项或者多项。或者，终端设备根据第一配置信息确定第一信道状态信息为宽带反馈或者窄带反馈。又或者，终端设备根据第一配置信息确定测量第一信道状态信息所采用的时频资源。又或者终端设备根据第一配置信息确定上报第一信道状态信息的时频资源，或者终端设备根据第一配置信息确定测量第一信道状态信息的时频资源的类型。
示例性地，第一反馈信息集合为NAAAAN，第一反馈信息集合包括6个反馈信息，假设6个反馈信息的优先级均为高。该第一反馈信息集合对应的第一配置信息可以包括：上报配置类型为P-CSI、上报的量包括CRI、PMI和CQI，测量第一信道状态信息的资源的类型配置信息可以为周期性资源。
示例性地，第一反馈信息集合为NNAAAN，第一反馈信息集合包括6个反馈信息，假设6个反馈信息的优先级均为高，NACK的数量为3大于第二阈值2。该第一反馈信息集合对应 的第一配置信息可以包括：上报配置类型为SP-CSI、上报的量包括CRI、RI、PMI和CQI，资源的类型配置信息可以为半持久性资源。可选地，第一配置信息对应的第一反馈信息集合包括至少一个高优先级的反馈信息且满足第一阈值、第二阈值、第三阈值和第四阈值中的一项或多项。
如此，终端设备可以根据不同的第一反馈信息集合，如第一反馈信息集合中包括的反馈信息的不同优先级，向网络设备发送不同的第一信道状态信息或第一上行参考信号，以满足不同业务的多样化需求。
在另一种可能的实施方式中，第一信道状态信息或第一上行参考信号可以是根据第二配置信息配置的，第二配置信息对应的第一反馈信息集合包括至少一个低优先级的反馈信息。
可选地，第一信道状态信息或第一上行参考信号与包括至少一个低优先级的反馈信息的第一反馈信息集合相对应。示例性地，网络设备可以根据包括至少一个低优先级的反馈信息的第一反馈信息集合确定第二配置信息，终端设备可以根据第二配置信息确定第一信道状态信息或第一上行参考信号，该第一信道状态信息或第一上行参考信号是由包括至少一个低优先级的反馈信息的第一反馈信息集合触发的。所述触发的含义是，若第一反馈集合满足第一条件，终端设备会发送第一信道状态信息或第一上行参考信号。也就是说，所述第一信道状态信息或第一上行参考信号是基于第一反馈集合触发的。
示例性地，可以通过如下方式确定第二配置信息对应的第一反馈信息集合包括至少一个低优先级的反馈信息。
例如，第二配置信息包括第二信息，第二信息与第一信道状态信息或第一上行参考信号相关联。
可选地，第二信息用于指示优先级。第二信息可指示高优先级或低优先级，例如，第二配置信息不包括指示高优先级的第二信息、或者第二信息包括指示低优先级的第二信息，则第二配置信息对应的第一反馈信息集合包括至少一个低优先级的反馈信息。包括至少一个低优先级的反馈信息的第一反馈信息集合触发的第一信道状态信息或者第一上行参考信号是通过第二配置信息配置的。
可选地，第二信息为CSI上报配置中的CQI表的指示信息。例如，第二信息指示CSI上报配置中的CQI表对应的BLER为10^-1，则第一配置信息对应的第一反馈信息集合包括至少一个低优先级的反馈信息。
可选地，第二配置信息与第一配置信息类似，第二配置信息是第一信道状态信息或第一上行参考信号相关的配置信息,该参考信号可以包括CSI-RS和/或SRS。例如，第二配置信息包括上述CSI资源配置(CSI-ResourceConfig)和/或CSI上报配置(CSI-ReportConfig)。第一信道状态信息可以是根据第二配置信息配置得到的。
可选地，由包括至少一个低优先级的反馈信息的第一反馈信息集合触发的第一信道状态信息或第一上行参考信号是根据第二配置信息配置的，具体含义可以为，终端设备根据第二配置信息确定第一信道状态信息或第一上行参考信号。具体实现方式可参照上述终端设备根据第一配置信息确定第一信道状态信息或第一上行参考信号的实现方式，此处不再赘述。
示例性地，第一反馈信息集合为NNAAAN，第一反馈信息集合包括6个反馈信息，假设6个反馈信息的优先级均为低。该第一反馈信息集合对应的第二配置信息可以包括：上报配置类型为A-CSI、上报的量包括CRI、PMI和CQI，资源的类型配置信息可以为非周期性资源。
又示例性地，第一反馈信息集合为NNAAAN，第一反馈信息集合包括6个反馈信息，假设6个反馈信息的优先级均为低，NACK的数量为3，大于第二阈值2。该第一反馈信息集合对应的第二配置信息可以包括：上报配置类型为P-CSI、上报的量包括CRI、RI、PMI和CQI，资源的类型配置信息可以为半持久性资源。也就是说，第二配置信息对应的第一反馈信息集合可以包括至少一个低优先级的反馈信息且满足第一阈值、第二阈值、第三阈值、和第四阈值中的一项或多项。
示例性地，第二配置信息可以与第一配置信息不相同，根据第一配置信息确定的第一信道状态信息与根据第二配置信息确定的第一信道状态信息不相同，如包括上报内容不相同、或者上报第一信道状态信息所采用的时频资源不相同，或者测量第一信道状态信息采用的时频资源不同。
也就是说，当第一反馈信息集合不同时，终端设备可以向网络设备发送不同的第一信道状态信息或第一上行参考信号，如第一信道状态信息的上报时刻、第一信道状态信息的内容、用于测量CSI的资源等可以是独立配置的。
如此，包括高优先级的反馈信息的第一反馈信息集合对应的业务与包括低优先级的反馈信息的第一反馈信息集合对应的业务可能具有不同的需求，为两者对应配置不同的配置信息，如上述第一配置信息和第二配置信息，从而可以针对不同的业务上报不同的第一信道状态信息或第一上行参考信号，可以满足不同业务的多样化需求。
可选地，本申请实施例提供的通信方法，还包括：网络设备向终端设备发送第一配置信息或第二配置信息。相应地，终端设备接收来自网络设备的第一配置信息或第二配置信息。
在一些实施方式中，本申请实施例提供的通信方法，还可以包括：终端设备向网络设备发送第一反馈信息集合。相应地，网络设备接收来自终端设备的第一反馈信息集合。
可选地，当终端设备未向网络设备发送第一反馈信息集合时，可以静默第一信道状态信息或第一上行参考信号的发送。相应地，当网络设备未接收来自终端设备的第一反馈信息集合时，静默第一信道状态信息或第一上行参考信号的接收。
其中，静默可以指不作某个/些动作、或取消某个/些动作。
示例性地，假设第一反馈信息集合为NNAAAN，第一反馈信息集合包括6个反馈信息，6个反馈信息的优先级均为低。如果终端设备未向网络设备发送该第一反馈信息集合、或者第一反馈信息集合的发送被取消，那么可以取消第一信道状态信息或第一上行参考信号的发送，或者不发送第一信道状态信息或第一上行参考信号，以节省信令开销。若仍向网络设备发送第一信道状态信息或第一上行参考信号，由于网络设备未接收到第一反馈信息集合，即使接收到第一信道状态信息或第一上行参考信号，也可能并不能获得该第一信道状态信息或第一上行参考信号是属于哪个终端设备的，从而不能准确地为终端设备调度数据传输，导致浪费信令开销。
基于图2所述的通信方法，终端设备确定第一反馈信息集合，并根据第一反馈信息集合确定是否向网络设备发送第一信道状态信息或第一上行参考信号，当第一反馈信息集合满足第一条件时，向网络设备发送第一信道状态信息或第一上行参考信号。如此，终端设备可以根据第一反馈信息集合确定是否发送信道状态信息或上行参考信号，无需频繁发送信道状态信息或上行参考信号，从而节省信令开销。此外，可以避免由网络设备触发信道的测量和信道状态信息的发送，可以缩短网络设备获得信道状态信息或上行参考信号的时延，从而满足低时延业务的需求。

其中，第五阈值、第六阈值、第七阈值和第八阈值可以是预设置的或预配置的。关于第二条件的具体实现方式与第一条件的实现方式类似，关于第二反馈信息集合是否满足第二条件的具体实现方式与上述第一反馈信息集合是否满足对应的第一条件的实现方式类似，具体可参照上述S202，此处不再赘述。
示例性地，本申请实施例中，确定第二反馈信息集合是否满足上述一项或多项条件的方式，可参照上述以NACK的特征是NACK的数量为例，确定第一反馈信息集合是否满足第一条件的方式，此处不再赘述。
需要说明的是，本申请实施例不对第一阈值至第八阈值的取值进行限定，第五阈值与第一阈值可以相同，也可以不相同，第二阈值与第六阈值、第三阈值与第七阈值、第四阈值与第八阈值可以相同。
在另一些实施方式中，本申请实施例提供的通信方法，还可以包括：S403，当第一反馈信息集合满足第一条件且第二反馈信息集合满足第二条件时，静默第二信道状态信息或第二上行参考信号的发送。相应地，网络设备静默第二信道状态信息或第二上行参考信号的接收。
示例性地，本申请不限定S403与上述S202之间的先后顺序，当第一反馈信息集合满足第一条件且第二反馈信息集合满足第二条件时，可以向网络设备发送第一信道状态信息或第一上行参考信号，并取消第二信道状态信息或第二上行参考信号的发送、或者不发送第二信道状态信息或第二上行参考信号，网络设备取消第二信道状态信息或第二上行参考信号的接收、或者不接收第二信道状态信息或第二上行参考信号，以节省信令开销。
此外，当终端设备已确定出第一反馈信息集合满足第一条件，可以不再确定第二反馈信息集合是否满足第二条件，以进一步节省终端设备的处理流程，节省终端设备的处理资源和功率。
在又一些实施方式中，本申请实施例提供的通信方法，还可以包括：S404，当第一反馈信息集合不满足第一条件且第二反馈信息集合满足第二条件时，终端设备可以向网络设备发送第二信道状态信息或第二上行参考信号。相应地，网络设备接收来自终端设备的第二信道状态信息或第二上行参考信号。
需要说明的是，终端设备可以根据第一反馈信息集合是否满足第一条件和/或第二反馈信息集合是否满足第二条件，执行上述S402、或S403、或S404。
示例性地，本申请不限定S403与上述S202之间的先后顺序，当第一反馈信息集合不满足第一条件且第二反馈信息集合满足第二条件时，终端设备可以向网络设备发送第二信道状态信息或第二上行参考信号，且不向网络设备发送第一信道状态信息或第一上行参考信号。

可选地，当终端设备未向网络设备发送第二反馈信息集合时，可以静默第二信道状态信息或第二上行参考信号的发送。相应地，网络设备静默第二信道状态信息或第二上行参考信号的接收。
也就是说，当第二反馈信息集合与包括至少一个高优先级的反馈信息的第一反馈信息集合在同一信道中传输时，如果终端设备一直未向网络设备发送第二反馈信息集合、或者第二反馈信息集合的发送被取消，那么可以取消第二信道状态信息或第二上行参考信号的发送，或者不发送第二信道状态信息或第二上行参考信号，网络设备取消第二信道状态信息或第二上行参考信号的接收、或者不接收第二信道状态信息或第二上行参考信号，以节省信令开销。若仍向网络设备发送第二信道状态信息或第二上行参考信号，由于网络设备未接收到第二反馈信息集合，即使接收到第二信道状态信息或第二上行参考信号，也可能并不能获得该第二信道状态信息或第二上行参考信号是属于哪个终端设备的，从而不能准确地为终端设备调度数据传输，导致浪费信令开销。
