Description

一种通信方法及相关设备 技术领域
本申请涉及通信技术领域，尤其涉及一种通信方法及相关设备。
背景技术
5G通信系统相比于前几代移动通信系统在传输速率、时延及功耗方面都提出了更高的要求，致力于支持更高系统性能，支持多种业务类型、不同部署场景和更宽的频谱范围。其中，增强移动宽带(enhanced mobile broadband,eMBB)，海量机器类型通信(massive machine type communication,mMTC)，超可靠低延迟通信(ultra-reliable and low latency communications,URLLC)是5G通信系统的三大典型应用场景。
目前，终端设备在解码获取数据时，如果数据信道解码出错，网络设备会给终端设备调度重传，重新发送数据，为了更精确给终端设备调度数据信道的时频资源，网络设备会触发终端设备接收或发送参考信号，从而提供更加准确的信道状态信息，进而提高通信系统的性能。目前参考信号的发送包括周期性发送、半永久性发送和非周期性的发送。对于非周期性的参考信号，如果终端设备数据信道解码出错，终端设备会反馈否定应答，相应的，网络设备在接收到该否定应答之后，向终端设备发送参考信号，终端设备接收到该参考信号之后，根据该参考信号测量信道状态信息，然后向网络设备反馈该信道状态信息，整个过程消耗的时间比较长，对于对时延要求比较高的URLLC业务来说，是不可行的。而对于周期性和半永久性的参考信号，终端设备会周期性的接收参考信号，并且根据参考信号周期性的反馈信道状态信息。这将会导致较大的开销，尤其是网络中设备数目比较多的时候，开销会非常明显。此外，对于URLLC业务而言，业务到达可能是随机的，即突发性业务，为了更好的测量信道，需要配置的信道状态信息-参考信号(channel state information-reference signal,CSI-RS)周期非常短，这将会进一步增加占用的资源。

NR系统中信道和干扰的测量主要是通过发送已知序列的参考信号(reference signal，RS)来测量信道或者干扰。NR系统中通常通过信道状态信息-参考信号(channel state information-reference signal,CSI-RS)测量下行信道的信道状态信息或者干扰，信道探测参考信号(sounding reference signal，SRS)测量上行信道的信道状态信息。当然，对于时分双工(time division duplex，TDD)系统，上下行链路的信道状态是对称的。因此，终端设备可以通过下行链路的信道状态获得上行数据传输的信道状态，或者可以通过上行链路的信道状态信息获得下行数据传输的信道状态信息。本申请实施例主要针对下行信道和干扰的测量进行介绍，但是上行数据信道测量也可以采用类似的方案，不赘述。
下行信道一般通过信道状态信息-参考信号CSI-RS进行测量。网络设备向终端设备发送CSI-RS相关的配置信息，终端设备接收该CSI-RS相关的配置信息，然后网络设备向终端设备发送CSI-RS，该CSI-RS用于终端设备测量信道和干扰，终端设备接收到CSI-RS之后，根据接收到的CSI-RS，计算需要测量的指标，例如，秩指示(rank indicator，RI)信息、预编码矩阵指示(pre-coding matrix indicator,PMI)信息、信道质量指示(channel quantity indicator,CQI)信息，然后根据CSI-RS相关的配置信息上报信道状态信息。该CSI-RS相关的配置信息包括信道状态信息-参考信号报告配置(CSI-RS ReportConfig)和信道状态信息-参考信号资源配置(CSI-RS ResourceConfig)，其中，CSI-RS ReportConfig用于配置信道上报有关的参数，例如，信道状态上报的类型，上报的测量的指标，CSI-RS ResourceConfig用于配置测量的时频资源的相关信息。
信道状态上报的类型可以分为3种，周期性信道状态信息(periodic channel state information，P-CSI)、半永久性信道状态信息(semipersistent channel state information，SP-CSI) 和非周期性信道状态信息(aperiodic channel state information，A-CSI)。如图2所示，图2表示周期性信道状态信息P-CSI的示意图。P-CSI是无线资源控制(radio resource control，RRC)配置的，周期性的发送，配置之后不需要触发。网络设备向终端设备发送配置信息，该配置信息不需要激活，然后网络设备向终端设备周期性的发送CSI-RS，相应的，终端设备周期性的接收该CSI-RS，然后根据该CSI-RS测量信道和干扰，然后上报信道状态信息。如图3所示，图3表示半永久性信道状态信息SP-CSI的示意图。SP-CSI是通过无线资源控制(radio resource control，RRC)配置的相关信息之后，不能直接使用，需要进一步触发。可以通过介质访问控制控制元素(medium access control control element，MAC CE)或者下行链路控制信息(downlink control information，DCI)触发，触发之后是周期性发送，通过MAC CE触发的SP-CSI在(physical uplink control channel，PUCCH)上发送信道状态信息，通过DCI触发的SP-CSI在物理上行共享信道(physical downlink shared channel，PUSCH)上发送信道状态信息。如图4所示，图4表示非周期性信道状态信息A-CSI的示意图，A-CSI是DCI触发的，触发后在指定的PUSCH上只上报一次信道状态信息。在本申请实施例中，信道状态信息和信道信息含义相同。
上报的测量的指标可以有秩指示RI信息、预编码矩阵指示PMI信息、信道质量指示CQI信息等，具体上报的测量指标可以通过在ReportConfig中配置变量进行选择全部上报或者只上报其中的一部分。
信道状态的上报还支持宽带反馈和窄带反馈。对于宽带反馈，则表示在整个上报带宽内只反馈一个值，而窄带反馈表示的是对每个子带(subband)分别反馈。并且，每个子带的大小在现有协议中有规定，具体如表格1所示，表格1表示现有协议中规定的子带大小，对于固定的带宽部分(bandwidth part，BWP)而言，每个子带包括的物理资源块(physical resource block，PRB)的数目是固定的。例如，一个BWP包含50个PRB，则其子带大小为4或者8，而具体是哪一个，则可以由高层信令规定。而且，针对于窄带反馈，还可以是离散的或者连续的进行反馈。

CSI-RS配置信息配置的资源也可以为三种，周期性的、半永久性的(semi-persistent)和非周期性的。信道状态上报类型和其对应的测量的时频资源的配置方式之间存在一定的关系，具体如表格2所示，表格2表示信道状态上报类型与CSI-RS配置信息配置的资源之间的关系。从表中可以看出，对于周期性配置的资源，可以支持P-CSI上报，SP-CSI上报和A-CSI上报，而对于非周期性的资源，仅仅支持A-CSI上报。

CSI-RS配置信息配置的资源从功能来看，可以分为三种，分别为用于信道测量的非零功率信道状态信息-参考信号(NZP-CSI-RS for channel)，用于干扰测量的零功率信道状态信息-参考信号(ZP-CSI-RS for interference)，用于干扰测量的非零功率信道状态信息-参考信号(NZP-CSI-RS for interference)，其中，NZP-CSI-RS for channel表示的是用于信道测量的非零功率信道状态信息-参考信号，该资源配置是必选的；ZP-CSI-RS for interference表示用于干扰测量的零功率信道状态信息-参考信号，该资源配置是可选的，如果CSI-RS配置信息配置了ZP-CSI-RS for interference，该资源集合中的资源和NZP-CSI-RS for channel资源集合中的资源一一对应；因为零功率信道状态信息-参考信号(ZP-CSI-RS)一般是用于测量干扰的，因此，一般也记做信道状态信息-干扰测量(channel state information–interference measurement，CSI-IM)。下面介绍零功率信道状态信息-参考信号(ZP-CSI-RS)和非零功率信道状态信息-参考信号(NZP-CSI-RS)之间的区别，ZP-CSI-RS是指网络设备在配置的资源上不发送任何信息，终端设备在该资源上进行检测，检测到的信号就是干扰，因为网络设备在该配置的资源上不发送任何信息。非零功率信道状态信息-参考信号(NZP-CSI-RS)是指网络设备在配置的资源上发送已知序列，终端设备通过该已知序列得到信道和/或干扰。
下面将介绍信道状态信息-参考信号报告配置(CSI-RS ReportConfig)中的几个参数，如图5所示，图5表示信道状态信息-参考信号报告配置(CSI-RS ReportConfig)，CSI-RS ReportConfig用于配置信道上报有关的参数，例如，信道状态上报的类型，上报的测量的指标：
(1)报告配置标识号(reportConfigId)是指信道状态信息-参考信号报告配置的标识号，用于标记信道状态信息-参考信号报告配置。
(2)用于信道测量的资源(resourcesForChannelMeasurement)配置用于信道测量的CSI-RS的资源，通过CSI-ResourceConfigId关联到该资源配置。
(3)用于干扰测量的信道状态信息-干扰测量资源(CSI-IM-RessourcesForInterference)配置用于干扰测量的CSI-RS的资源，通过CSI-ResourceConfigId关联到该资源配置，在本申请实施例中，也会用ZP-CSI-RS资源来描述用于测量干扰的资源。
(4)用于干扰测量的非零功率信道状态信息-参考信号资源(NZP-CSI-RS-ResourcesForInterference)：配置用于干扰测量的NZP-CSI-RS资源，通过CSI-ResourceConfigId关联到该资源配置。
(5)报告配置类型(reportConfigType)：信道状态的上报的类型，可以分为周期性上报，半永久性上报和非周期上报。
(6)报告质量(reportQuantity)：上报的测量的指标，可以通过不同的配置，选择让终端设备上报不同的指标，包括CRI,RI,PMI,CQI等等。
下面将介绍信道状态信息资源配置(CSI ResourceConfig)中的几个参数，如图6所示，图6表示信道状态信息资源配置(CSI ResourceConfig)，CSI ResourceConfig用于配置测量的时频资源的相关信息：
(1)信道状态信息资源配置标识号(csi-ResourceConfigId)：该csi-ResourceConfig的标识号ID，用于标记该csi-ResourceConfig，通过该变量关联到CSI-ReportConfig；
(2)信道状态信息-参考信号资源集合的队列(csi-RS-ResourceSetList)：配置资源结合的队列，其中可以包括用于信道测量的资源集合，用于干扰测量的资源集合。其中通过非非零功率信道状态信息-参考信号资源集合标识号NZP-CSI-RS-ResourceSetId和/或用于信道状态信息-干扰测量资源集合标识号CSI-IM-ResourceSetId关联到资源集合的配置。非零功率信道状态信息-参考信号资源集合NZP-CSI-RS-ResourceSet和信道状态信息-干扰测量资源集合CSI-IM-ResourceSet中配置的资源的主要区别是，在NZP-CSI-RS资源中会发送已知序列的CSI-RS，通过已知序列的CSI-RS信号测量信道或者干扰；而CSI-IM资源也叫做ZP-CSI-RS资源，在该资源上不发送任何信息，接收到的信息均为干扰。
(3)资源的类型(resourceType)：可以分为周期性(periodic)资源，半持久性(semipersistent)资源和非周期性(aperiodic)资源。
下面将介绍非零功率信道状态信息-参考信号资源集合(NZP-CSI-RS-ResourceSet)中的几个参数，如图7所示，图7表示非零功率信道状态信息-参考信号资源集合(NZP-CSI-RS-ResourceSet)。NZP-CSI-RS-ResourceSet用于配置非零功率NZP的CSI-RS资源集合，其中可以包括至少一个资源。终端设备根据这些资源测量信道状态信息，并反馈该信道状态信息。当一个资源集合中存在多个资源时，终端设备具体反馈的是哪个资源上测量得到的信道状态信息，会通过终端设备反馈的信道状态信息-参考信号资源指示信息(channel state information-reference signal resource indicator，CRI)变量指示，例如CRI＝0，表示终端设备反馈的信道状态信息是通过资源集合中id＝0的资源上测量得到的信道状态信息。
(1)非零功率信道状态信息资源集合标识号(nzp-CSI-ResourceSetId)：用于标识非零功率信道状态信息资源集合的标识号。
(2)非零功率信道状态信息-参考信号资源(nzp-CSI-RS-Resources)：该资源集合中包括的资源，通过NZP-CSI-RS-ResourceId关联到每个NZP-CSI-RS资源，如图8所示，图8表示非零功率信道状态信息-参考信号资源(nzp-CSI-RS-Resources)。
信道状态信息-干扰测量资源集合(CSI-IM-ResourceSet)配置用于测量干扰的资源集合，具体如图9所示，图9表示信道状态信息-干扰测量资源集合。
信道状态信息-干扰测量资源(CSI-IM-Resource)配置用于测量干扰的资源的相关信息，通过CSI-IM-ResourceId关联到CSI-IM-ResourceSet。
下面将介绍不同信道状态信息CSI报告的优先级：
(1)对于周期性信道状态信息P-CSI，优先级为低优先级。
(2)对于半永久性SP-CSI，通过MAC CE触发，在PUCCH上发送的SP-CSI的优先 级为低优先级；对于通过DCI触发的SP-CSI，其优先级和DCI中指示信息的优先级保持一致，DCI中指示信息为高优先级，则其为高优先级，指示为低优先级，则为低优先级。
(3)对于非周期性A-CSI，需要通过DCI触发，其优先级和DCI中指示信息的优先级保持一致，DCI中指示信息为高优先级，则其为高优先级，指示为低优先级，则为低优先级。
超可靠低延迟通信(ultra-reliable and low latency communications,URLLC)业务主要用于无人驾驶、车联网、自动工厂和远程医疗等领域，要求低时延和高可靠性。
增强移动宽带(enhanced Mobile Broadband,eMBB)业务主要用于超高清时频、全息技术、增强现实和虚拟现实等应用，对网络带宽和速率要求比较高。
实施例一：
目前，当用于终端设备发送信道状态信息的资源与发送其他数据的资源的发生重叠时，如何发送信道状态信息和其他数据是本领域人员正在解决的技术问题。一般而言，会通过优先级信息来判断是发送信道状态信息，或者其他数据，或者信道状态信息和其他数据复用之后再发送。但是，对于通过终端设备解码下行数据失败时对应的信道状态信息的发送，如何确定信道状态信息对应的优先级是本领域尚未解决的问题，因此，本实施例提出以下解决方案。
请参见图10，图10是本申请实施例提供的一种通信方法，该方法包括：
步骤S1001：网络设备向终端设备发送配置信息。
具体地，该配置信息中可以包括下行数据的时频资源位置、下行参考信号的时频资源位置、下行参考信号的周期性、周期和用于终端设备发送信道状态信息的时频资源的指示信息等一项或者多项。在一种示例中，该下行参考信号可以为信道状态信息-参考信号CSI-RS。
步骤S1002：终端设备接收来自网络设备的配置信息。
具体地，终端设备在接收该配置信息之后，可以根据该配置信息确定下行数据的时频资源位置、下行参考信号的时频资源位置、下行参考信号的周期性和用于终端设备发送信道状态信息的时频资源的指示信息等一项或者多项，也就是说能够根据该配置信息确定在哪个时频资源位置去接收下行数据、在哪个时频资源位置去接收下行参考信号、以及确定下行参考信号发送的周期性、以及确定用于发送信道状态信息的时频资源等一项或者多项。
可选地，所述信道状态信息是根据所述配置信息确定的。可选的，终端设备可以通过所述配置信息确定所述信道状态信息包括的具体参数，例如为CQI信息、秩指示RI信息、预编码矩阵指示PMI信息、信道状态信息参考信号资源索引CRI信息和干扰信息中的一项或者多项。可选的，终端设备可以通过所述配置信息确定所述信道状态信息中包括的频域资源粒度，即所述信道状态信息为宽带反馈或者窄带反馈。
步骤S1003：网络设备向终端设备发送下行数据。
具体地，该下行数据可以是通过下行链路控制信息DCI调度的，网络设备向终端设备发送DCI，该DCI用于调度该下行数据，下行数据可以为PDSCH。可选的，该下行数据可以是半静态调度(semi-persistent scheduling，SPS)的，也就是说，网络设备在初始调度时通 过DCI指示终端设备当前的调度信息，终端设备识别是半静态调度，则终端设备保持当前的调度信息，然后网络设备可以每隔固定的周期在相同的时频资源位置上向终端设备发送下行数据，相应的，终端设备每隔固定的周期在相同的时频资源位置上接收来自网络设备的下行数据。
步骤S1004：终端设备接收来自网络设备的下行数据。
步骤S1005：当下行数据解码失败时，终端设备确定信道状态信息的第一信息。
具体地，当下行数据是通过DCI调度的，下行数据解码失败可以指，第一种情况是PDCCH解码错误，第二种情况，解码PDCCH正确但PDSCH解码错误。第一信息可以为优先级信息。信道状态信息可以用于网络设备重新发送下行数据，或者传输新的下行数据。信道状态信息可以包括信道质量指示CQI信息、秩指示RI信息、预编码矩阵指示PMI信息、信道状态信息参考信号资源索引CRI信息和干扰信息中的一项或者多项。
可选的，该信道状态信息的第一信息用于确定是否向网络设备发送信道状态信息。如图11所示，当所述信道状态信息对应的时频资源与第四信息对应的时频资源发生重叠(overlap)时，根据信道状态信息的第一信息和第四信息对应的第一信息判断是否向网络设备发送信道状态信息。在一种示例中，信道状态信息的第一信息为第三状态，第四信息对应的第一信息为第四状态，则终端设备确定向网络设备发送信道状态信息。在又一种示例中，信道状态信息的第一信息为第四状态，第四信息对应的第一信息为第三状态，则终端设备不向网络设备发送信道状态信息。在又一种示例中，信道状态信息的第一信息和第四信息对应的第一信息相同，则将信道状态信息和第四信息复用(multiplex)之后传输。其中，第一信息可以为优先级信息，第三状态为高优先级，第四状态为低优先级。
可选的，复用是指将信道状态信息和第四信息在一个信道中传输。可选的，将两个或者两个以上信息复用传输时，所述的两个或者多个以上的信息可以联合编码。第四信息可以为上行数据信息、上行确定应答ACK或否定应答NACK信息、第二信道状态信息和调度请求(scheduling request,SR)信息中的一项或者多项。所述第二信道状态信息是区别于所述信道状态信息的其他信道状态信息。
在一种示例中，重叠可以为时域发生重叠，具体的，如图11所示，时域重叠指的是两个时频资源对应的时域资源部分或者全部是相同的。可选的，时域重叠可以为两个时频资源对应的时域资源中至少有一个符号是相同的。所述的两个时频资源分别为信道状态信息的时频资源和第四信息的对应的时频资源。在又一种示例中，重叠可以为频域发生重叠，具体的，如图12所示，频域重叠指的是两个时频资源对应的频域资源部分或者全部相同。所述的两个时频资源分别为信道状态信息的时频资源和第四信息的时频资源。
可选的，信道状态信息的第一信息和信道状态信息的第一参数相关。其中，所述第一参数可以为下列参数中的一项或者多项：信道状态信息对应的时频资源、信道状态信息对应的时频资源的指示信息、信道状态信息的编码速率、以及信道状态信息在映射到时频资源时的映射顺序。如图13所示，当信道状态信息的时频资源与第五信息的时频资源发生重叠时，通过第一信息确定第一参数。
在一种示例中，当所述第一参数为时频资源或者时频资源的指示信息时，当两个时频资源发生重叠时，在第一时频资源中传输信道状态信息和第五信息。具体的，如果信道状 态信息的第一信息为第三状态，第五信息的第一信息为第四状态，则信道状态信息对应的时频资源的第一个符号在第五信息对应的时频资源的第一个符号之前，如图14所示。
在又一种示例中，当所述第一参数为信道状态信息的编码速率时。当两个时频资源发生重叠，则将信道状态信息和第五信息复用之后传输。将信道状态信息和第五信息重新编码，所述信道状态信息的编码速率为R1，第五信息的编码速率为R2。如果信道状态信息的第一信息为第三状态，所述第五信息的第一信息为第四状态，则R1大于R2。如果信道状态信息的第一信息为第四状态，所述第五信息的第一信息为第三状态，则R1小于R2。如果信道状态信息的第一信息和第五信息的第一信息相同，则R1和R2相等。
在又一种示例中，当所述第一参数为信道状态信息映射到时频资源的映射顺序时。如果信道状态信息的第一信息为第三状态，所述第五信息的第一信息为第四状态，则信道状态信息先于第五信息映射。如果信道状态信息的第一信息为第四状态，所述第五信息的第一信息为第三状态，则第五信息先于信道状态信息映射到时频资源。
在一种可能的实现方式中，当所述下行数据解码失败时，确定信道状态信息的第一信息，包括：信道状态信息的第一信息与否定应答NACK的第一信息相同。
具体地，第一信息可以为优先级信息。该否定应答NACK用于表示下行数据解码失败。也就是说，以第一信息为优先级信息为例，当否定应答NACK的优先级为高优先级时，信道状态信息的优先级为高优先级；当否定应答NACK的优先级为低优先级时，信道状态信息的优先级为低优先级。
在又一种可能的实现方式中，终端设备接收来自网络设备的第一DCI，该第一DCI用于指示否定应答NACK的第一信息。
在一种示例中，以第一信息为优先级信息为例，终端设备接收来自网络设备的第一DCI，该第一DCI用于指示否定应答NACK的优先级为高优先级。在又一种示例中，终端设备接收来自网络设备的第一DCI，该第一DCI用于指示否定应答NACK的优先级为低优先级。
在一种可能的实现方式中，当下行数据解码失败时，确定信道状态信息的第一信息，包括：根据配置信息，确定信道状态信息的第一信息。具体地，第一信息可以为优先级信息。具体地，根据配置信息确定信道状态信息的第一信息可以包括以下4种情况：

第2种情况：根据配置信息确定信道状态信息为半永久性信道状态信息SP-CSI；接收来自网络设备的第二下行控制信息DCI，第二DCI用于指示SP-CSI的第一信息。具体地， 第一信息可以为优先级信息。在一种示例中，以第一信息为优先级信息为例，终端设备根据配置信息确定信道状态信息为半永久性信道状态信息SP-CSI，终端设备接收来自网络设备的第二下行控制信息DCI，该第二DCI用于指示SP-CSI的优先级为高优先级，那么该信道状态信息的优先级为高优先级。在一种示例中，配置信息中可以包括指示信息，该指示信息用于指示所述信道状态信息为半永久性信道状态信息SP-CSI。可选的，指示信息可以为图5中所示的reportConfigType，相应的，终端设备可以根据图5中所示的reportConfigType确定信道状态信息为半永久性信道状态信息SP-CSI。
第3种情况：根据配置信息确定信道状态信息为半永久性信道状态信息SP-CSI；接收来自网络设备的介质访问控制控制元素MAC CE；在MAC CE用于激活配置信息的情况下，半永久性信道状态信息SP-CSI的第一信息为第一状态。具体地，第一信息可以为优先级信息，第一状态可以为低优先级。在一种示例中，以第一信息为优先级信息为例，终端设备根据配置信息确定信道状态信息为SP-CSI，终端设备接收来自网络设备的MAC CE，在该MAC CE用于激活该配置信息的情况下，SP-CSI的优先级为低优先级，那么终端设备确定信道状态信息的优先级为低优先级。在一种示例中，配置信息中可以包括指示信息，该指示信息用于指示所述信道状态信息为半永久性信道状态信息SP-CSI。可选的，指示信息可以为图5中所示的reportConfigType相应的，终端设备可以根据图5中所示的reportConfigType确定信道状态信息为半永久性信道状态信息SP-CSI。
第4种情况：根据所述配置信息确定所述信道状态信息为非周期信道状态信息A-CSI；接收来自所述网络设备的第三下行控制信息DCI，所述第三DCI用于指示所述非周期信道状态信息A-CSI的第一信息。具体地，第一信息可以为优先级信息。在一种示例中，以第一信息为优先级信息为例，终端设备根据配置信息确定信道状态信息为非周期信道状态信息A-CSI，终端设备接收来自网络设备的第三下行控制信息DCI，该第三DCI用于指示SP-CSI的优先级为高优先级，那么该信道状态信息的优先级为高优先级。在一种示例中，配置信息中可以包括指示信息，该指示信息用于指示所述信道状态信息为非周期信道状态信息A-CSI。可选的，指示信息可以为图5所示的reportConfigType，相应的，终端设备可以根据图5中所示的reportConfigType确定信道状态信息为非周期信道状态信息A-CSI。
在又一种可能的实现方式中，当下行数据解码失败时，确定信道状态信息的第一信息，包括：终端设备确定信道状态信息的第一信息为第二状态，其中，配置信息对应的信道状态信息的第一信息为第一状态。具体地，第一信息可以为优先级信息，第二状态可以为高优先级，第一状态为低优先级。
在一种示例中，以第一信息为优先级信息，第一状态为低优先级，第二状态为高优先级为例，终端设备确定配置信息对应的信道状态信息为周期性信道状态信息P-CSI，周期性信道状态信息P-CSI的优先级为低优先级，此时，由于该信道状态信息是通过NACK触发的，终端设备确定信道状态信息的优先级为高优先级。在又一种示例中，终端设备确定配置信息对应的信道状态信息为半永久性信道状态信息SP-CSI，在介质访问控制控制元素MAC CE用于激活该配置信息的情况下，该配置信息对应的半永久性信道状态信息SP-CSI的优先级为低优先级，此时，由于该信道状态信息是通过NACK触发的，终端设备确定信 道状态信息的优先级为高优先级。在又一种示例中，终端设备确定配置信息对应的信道状态信息为半永久性信道状态信息SP-CSI，在第二DCI用于激活该配置信息的情况下，第二DCI指示SP-CSI的优先级为低优先级，那么该配置信息对应的半永久性信道状态信息SP-CSI的优先级为低优先级，此时，由于该信道状态信息是通过NACK触发的，终端设备确定信道状态信息的优先级为高优先级。在又一种示例中，终端设备确定配置信息对应的信道状态信息为非周期性信道状态信息A-CSI，在第三DCI用于激活该配置信息的情况下，第三DCI指示A-CSI的优先级为低优先级，那么该配置信息对应的非周期性信道状态信息A-CSI的优先级为低优先级，此时，由于该信道状态信息是通过NACK触发的，终端设备确定信道状态信息的优先级依然为高优先级。
在又一种可能的实现方式中，当下行数据解码失败时，确定信道状态信息的第一信息，包括：根据所述配置信息确定的信道状态信息的第一信息为第一状态，若所述下行数据解码失败，则所述信道状态信息的第一信息为第二状态。具体地，第一信息可以为优先级信息，第二状态可以为高优先级，第一状态为低优先级。示例性的，如果下行数据解码失败，则信道状态信息的第一信息从第一状态改变为第二状态。具体示例可参照终端设备确定信道状态信息的第一信息为第二状态，其中，配置信息对应的信道状态信息的第一信息为第一状态的实现方式对应的示例此处不再赘述。
在该方案中，所述信道状态信息的第一信息的状态在数据信道解码失败和其他情况是不同的。以第一信息为优先级为例，当数据信道解码失败时，所述信道状态信息的优先级为高优先级。在该情况下，能够尽可能保证在信道状态信息的时频资源和其他数据的时频资源发生重叠时，信道状态信息的正常发送。有利于在信道状态解码失败时，网络设备获得更为精确的信道状态信息。
步骤S1006：终端设备向网络设备发送否定应答NACK。
具体地，该否定应答NACK用于表示下行数据解码失败。
步骤S1007：网络设备接收来自终端设备的否定应答NACK。
在上述方法中，当网络设备配置的用于终端设备发送信道状态信息的时频资源与其他数据的时频资源重叠时，如何根据信道状态信息的第一信息确定如何发送信道状态信息或其他数据，也就是说解决了当时频资源重叠时，如何发送信道状态信息和/或其他数据的问题。

实施例二：
请参见图16，图16是本申请实施例提供的一种通信方法，该方法包括：
步骤S1601：网络设备向终端设备发送第一配置信息。
具体地，第一配置信息可以包括下行数据的时频资源位置、下行参考信号的时频资源位置、下行参考信号的周期和用于终端设备发送信道状态信息、上行参考信号的时频资源的指示信息、上行参考信号的周期等一项或者多项。在一种示例中，该下行参考信号可以为信道状态信息-参考信号CSI-RS。在一种示例中，该上行参考信号为SRS。
步骤S1602：终端设备接收来自网络设备的第一配置信息。
具体地，终端设备可以根据该第一配置信息确定下行数据的时频资源位置、下行参考信号的周期和用于终端设备发送信道状态信息或上行参考信号的时频资源的指示信息等一项或者多项，也就是说终端设备能够根据该第一配置信息确定在哪个时频资源位置去接收下行数据、在哪个时频资源位置去接收下行参考信号、以及下行参考信号发送的周期、以及确定用于发送信道状态信息或上行参考信号的时频资源等一项或者多项。
步骤S1603：网络设备向终端设备发送下行数据。
具体参照步骤S1003，此处不再赘述。
步骤S1604：终端设备接收来自网络设备的下行数据。
步骤S1605：当下行数据解码失败、且否定应答NACK满足第三条件时，终端设备向网络设备发送信道状态信息或上行参考信号。
具体地，否定应答NACK用于表示下行数据解码失败。第三条件可以所述否定应答NACK的第一信息为第五状态，第三条件还可以为所述否定应答NACK的第一信息为第六状态，且否定应答NACK连续出现K次，K为正整数。其中K可以是网络设备指示的，也可以是协议规定的。其中，第一信息可以为优先级信息，第五状态为高优先级，第六状态为低优先级。在一种示例中，所述否定应答NACK的第一信息为第六状态，且否定应答NACK连续出现K次的含义是：终端设备检测下行数据信道，连续有K次解码失败，且该NACK的第一信息为第六状态。所述连续，具体表示的是终端设备接收到K次下行数据，K次下行数据均解码失败。下面以K＝3为例描述。假设终端设备接收到5个下行数据，对5个下行数据解码，得到的结果分别是{ACK,ACK,NACK,NACK,NACK}。其中ACK表示下行数据信道解码正确。其中，连续出现了3次NACK，如果这三次NACK对应的第一信息均为第六状态，则表明否定应答NACK满足第三条件。又一个示例，假设终端设备接收到5个下行数据，解码的结果分别是{NACK,ACK,NACK,NACK,ACK}，虽然也出现了3次NACK，但是并没有连续出现，因此不满足第三条件。又一个示例，假设终端设备接收到5个下行数据，解码的结果分别是{ACK,ACK,NACK,NACK,NACK}，连续出现了3个NACK，但是其中第三个NACK对应的第一信息为第五状态，此时，不满足第三条件。
具体地，信道状态信息可以包括信道质量指示CQI信息、秩指示RI信息、预编码矩阵指示PMI信息、信道状态信息参考信号资源索引CRI信息和干扰信息中的一项或者多项。 在一种示例中，当信道状态信息包括信道质量指示CQI信息和/或干扰信息时，终端设备测量信道质量指示CQI信息和/或干扰信息，不测量或者不更新秩指示RI信息和预编码矩阵指示PMI信息。信道状态信息可以用于网络设备重新发送下行数据，或者传输新的下行数据。可选的，上行参考信号是SRS信号，该上行参考信号可以用于网络设备测量上行信道。在TDD系统中，网络设备可以利用上下行链路的信道是对称的，从而通过上行信道信息获取下行信道信息。其中，不测量或者不更新RI信息和PMI信息表示的是在确定RI信息和预编码矩阵指示PMI信息时不进行测量或更新。具体的，也就是说，确定RI信息和PMI信息时可以通过网络设备直接指示信息确定，或者采用预设的值，或者采用之前测量的得到的值确定。由于当终端设备反馈的变量越多，表示需要测量的变量越多，那么测量所需要花费的计算资源和时间就会越多。因此通过这样的方式，如果终端设备仅仅反馈CQI信息和/或干扰信息，就只需要测量CQI信息和/或干扰信息，就能够有效的降低处理时延，更及时的反馈信道状态信息。
在上述方法中，通过当下行数据解码失败、且否定应答NACK满足第三条件时，终端设备向网络设备发送信道状态信息或上行参考信号的方式，能够在一般情况下，高优先级的业务对于开销和时延更为敏感，所以对于高优先级的业务支持NACK触发，能够更匹配业务特性。对于低优先级的业务，对于时延不敏感，能够通过混合自动重传(hybrid automatic repeat request，HARQ)提高可靠性，因此，通过设置K能够进一步降低开销。
在一种可能的实现方式中，当下行数据解码失败、且否定应答NACK满足为第三条件时，终端设备根据第一配置信息向网络设备发送信道状态信息或上行参考信号。
具体地，第一配置信息中配置了用于终端设备发送信道状态信息或上行参考信号的时频资源。或者，第一配置信息中配置了所述信道状态信息的频域粒度，即信道状态信息是窄带反馈还是宽带反馈。又或者，第一配置信息中配置了所述信道状态信息包含的具体参数。所述信道状态信息包含的参数如前所述，不赘述。
在一种示例中，假设第一配置信息中配置的用于终端设备发送信道状态信息或上行参考信号的时频资源，第三条件为所述信道状态信息的第一信息为高优先级，那么当下行解码失败、且否定应答NACK的优先级为高优先级时，终端设备在第一配置信息中配置的用于终端设备发送信道状态信息或上行参考信号的时频资源上向网络设备发送信道状态信息或上行参考信号。
在又一种可能的实现方式中，终端设备接收来自网络设备的第五DCI，该第五DCI用于指示否定应答NACK的第一信息。
例如，以第一信息为优先级信息为例，终端设备接收来自网络设备的第五DCI，该第五DCI用于指示否定应答NACK的优先级为高优先级，或者，终端设备接收来自网络设备的第五DCI，该第五DCI用于指示否定应答NACK的优先级为低优先级。
在又一种可能的实现方式中，终端设备接收来自网络设备的下行参考信号。具体地，该下行参考信号可以为信道状态信息-参考信号CSI-RS，该下行参考信号用于终端设备测量信道状态信息。
在又一种可能的实现方式中，该信道状态信息是根据下行数据的解调参考信号DMRS确定的。
在又一种可能的实现方式中，当下行数据解码失败时、且满足第三条件时，终端设备在第二时频资源上向网络设备发送信道状态信息。
在又一种可能的实现方式中，当下行数据解码失败时，终端设备在第二时频资源上向网络设备发送信道状态信息。
其中，在一种示例中，该第二时频资源和解码失败的下行数据的时频资源对应。通过这样的方式，可以通过下行数据的时频资源确定第二时频资源，因此，能够节省用于指示第二时频资源的开销。
在又一种示例中，该第二时频资源和用于反馈否定应答NACK的时频资源对应。所述否定应答NACK表示所述下行数据解码失败。通过这样的方式，可以通过反馈否定应答NACK的时频资源确定第二时频资源，能够节省用于指示第二时频资源的开销。
在又一种示例中，该第二时频资源为用于反馈否定应答NACK的时频资源。所述否定应答NACK表示所述下行数据解码失败。通过这样的方式，信道状态信息和否定应答NACK在同一块时频资源反馈，不需要分别通过指示信息指示两个独立的时频资源，能够节省信令开销。
在又一种示例中，该第二时频资源可以为第一配置信息配置的，当下行数据解码成功、或者没有下行数据时，在第一配置信息配置的时频资源上实际上是不发送信道状态信息的。如图17所示，图17表示一种发送信道状态信息的示意图。网络设备配置了5个用于反馈信道状态信息的时频资源，分别为第一个时频资源、第二个时频资源、第三个时频资源、第四个时频资源、第五个时频资源。终端设备只有当下行数据解码失败且满足第三条件、或者下行数据解码失败时，终端设备在第二时频资源上向网络设备发送信道状态信息，如图17所示，解码失败的下行数据的时频资源对应为第三个时频资源，那么第二时频资源为第三个时频资源。终端设备在第三个时频资源上向网络设备发送信道状态信息，在第一个时频资源、第二个时频资源、第四个时频资源和第五个时频资源上不发送信道状态信息。
步骤S1606：终端设备向网络设备发送否定应答NACK。
具体地，该否定应答NACK用于表示下行数据解码失败。
步骤S1607：网络设备接收来自终端设备的否定应答NACK。
在上述方法中，针对不同的业务类型，支持的参考信号的发送和信道状态信息的反馈应该是不同的。例如，对于URLLC业务，信道状态信息反馈可能需要快速反馈，信道状态信息最好是窄带信息。对于eMBB业务而言，快速反馈的需求不高。本申请实施例提出了一种当下行数据解码失败、且否定应答NACK的第一信息为第三条件时，终端设备向网络设备发送信道状态信息或上行参考信号，通过这样的方式，能够保证高优先级的业务，例如URLLC业务快速的反馈，减少开销，保证通信性能。

在一种示例中，假设终端设备接收来自网络设备的至少两个配置信息包括第一配置信息和第二配置信息，其中，第二配置信息包括第七信息，第七信息为信道状态信息报告CSI-Report中配置的信道状态信息表格CQI-Table对应的传输块错误概率为10 -1或者用于指示信道状态信息报告CSI-Report中配置的信道状态信息表格CQI-Table对应的传输块错误概率为10 -1，那么终端设备可以根据第七信息确定第二配置信息对应的第一信息为低优先级或低优先级业务类型，那么终端设备可以根据第七信息确定第二配置信息对应低优先级的业务类型，确定第一配置信息对应高优先级的业务类型。

频域指示信息包括频域粒度指示信息和频域带宽。频域带宽表示信道测量的带宽。频域粒度如上述介绍，可以为窄带反馈或者宽带反馈。如果为窄带反馈，每种带宽部分BWP下，有两种窄带的配置，如表格1所示。由于URLLC业务一般业务包比较小，在分配资源的时候占用的资源有限，例如为5个RB，因此，对于URLLC业务而言，窄带反馈更为有效和常见；相对应的，对于eMBB业务而言，宽带反馈就能够有比较好的效果。因此，通过频域粒度可以隐含的指示配置信息和业务类型的对应关系，而且不需要额外的指示信息。

具体可以参考步骤S1003，此处不再赘述。
步骤S1804：终端设备接收来自网络设备的下行数据。
步骤S1805：当下行数据解码失败时，终端设备根据第一配置信息向所述网络设备发送信道状态信息或上行参考信号。
具体地，第一配置信息为至少两个配置信息中的一个，第一配置信息对应的第一信息与否定应答NACK的第一信息相同，否定应答NACK用于表示下行数据解码失败。也就是说，NACK的第一信息触发对应的配置信息。可选的，所述的第一配置信息对应的第一信息与否定应答NACK的第一信息相同可以指第一信息的内容相同。例如，当第一信息为优先级信息时，所述的第一配置信息对应的第一信息为高优先级，如果否定应答NACK的第一信息也为高优先级，则二者相同。类似的，当所述第一配置信息对应的第一信息为低优先级，若否定应答NACK的第一信息为低优先级，则二者相同。
第一信息可以为优先级信息或者用于指示第一配置信息对应的业务类型。第一配置信息中包括用于发送信道状态信息或上行参考信号的时频资源。
具体地，信道状态信息可以包括信道质量指示CQI信息、秩指示RI信息、预编码矩阵指示PMI信息、信道状态信息参考信号资源索引CRI信息和干扰信息中的一项或者多项。在一种示例中，当信道状态信息包括信道质量指示CQI信息和/或干扰信息时，终端设备测量信道质量指示CQI信息和/或干扰信息，不测量或者不更新秩指示RI信息和预编码矩阵指示PMI信息。信道状态信息可以用于网络设备重新发送下行数据，或者传输新的下行数据。可选的，上行参考信号可以是SRS信号。该上行参考信号可以用于网络设备测量上行信道。其中，不测量或者不更新RI信息和PMI信息表示的是在确定RI信息和预编码矩阵指示PMI信息时不进行测量或更新。具体的，也就是说，确定RI信息和PMI信息时可以通过网络设备直接指示信息确定，或者采用预设的值，或者采用之前测量的得到的值确定。当终端设备反馈的变量越多，表示需要测量的变量越多，因此，测量所需要花费的计算资源和时间就会越多。如果终端设备仅仅反馈CQI信息和/或干扰信息，就只需要测量CQI信息和/或干扰信息，就能够有效的降低处理时延，更及时的反馈信道状态信息。
在一种示例中，第一配置信息对应的优先级与否定应答NACK的优先级相同，以第一信息为优先级信息为例，例如，否定应答NACK的优先级为高优先级，第一配置信息对应的优先级为高优先级；例如，否定应答NACK的优先级为低优先级，第一配置信息对应的优先级为低优先级；以第一信息用于指示第一配置信息对应的业务类型为例，例如，否定 应答NACK的第一信息为高优先级的业务类型，第一配置信息对应的第一信息为高优先级的业务类型，例如，否定应答NACK的第一信息为低优先级的业务类型，第一配置信息对应的第一信息为低优先级的业务类型。
在又一种可能的实现方式中，终端设备接收来自网络设备的第四DCI，该第四DCI用于指示否定应答NACK的第一信息。
在一种示例中，以第一信息为优先级信息为例，终端设备接收来自网络设备的第四DCI，该第四DCI用于指示否定应答NACK的优先级为高优先级。在又一种示例中，终端设备接收来自网络设备的第四DCI，该第四DCI用于指示否定应答NACK的优先级为低优先级。
在又一种可能的实现方式中，终端设备接收来自网络设备的下行参考信号。具体地，该下行参考信号可以为信道状态信息-参考信号CSI-RS，该下行参考信号用于终端设备测量信道状态信息。
在又一种可能的实现方式中，该信道状态信息是根据下行数据的解调参考信号DMRS确定的。
步骤S1806：终端设备向网络设备发送否定应答NACK。
具体地，该否定应答NACK用于表示下行数据解码失败。
步骤S1807：网络设备接收来自终端设备的否定应答NACK。
在上述方法中，不同业务类型对应不同的配置信息，例如，对于高优先级的业务，如URLLC业务，对应的配置信息配置的资源可以比较密集，而对于低优先级的业务，如eMBB业务，对应的配置信息配置的资源可以比较稀疏，通过这样的区别配置配置信息的资源的方式能够在保证通信性能的同时，更好的适用于不同业务的需求。
