为便于更好的理解本申请实施例，对本申请相关的下行非相干传输进行说明。
在NR系统中引入了基于多个传输点/发送接收点(Transmission/reception point，TRP)的下行和上行的非相干传输。其中，TRP之间的回传(backhaul)连接可以是理想的或者非理想的，理想的backhaul下TRP之间可以快速动态的进行信息交互，非理想的backhaul下由于时延较大TRP之间只能准静态的进行信息交互。在下行非相干传输中，多个TRP可以采用不同的控制信道独立调度一个终端的多个物理下行共享信道(Physical Downlink Shared Channel，PDSCH)传输，也可以采用同一个控制信道调度不同TRP的传输，其中不同TRP的数据采用不同的传输层，后者只能用于理想backhaul的情况。
对于采用多个物理下行控制信道(Physical Downlink Control Channel，PDCCH)调 度的下行传输，所调度的PDSCH可以在相同的时隙或不同的时隙传输。终端需要支持同时接收来自不同TRP的PDCCH和PDSCH。终端反馈肯定应答(Acknowledgement，ACK)/否定应答(Negative Acknowledgement，NACK)和信道状态信息(Channel State Information，CSI)时，可以将ACK/NACK和CSI各自反馈给传输相应PDSCH的不同TRP(如图2中的A)，也可以合并上报给一个TRP(如图2中的B)。前者可以应用于理想backhaul和非理想backhaul两种场景，后者只能用于理想backhaul的场景。其中，不同TRP传输的用于调度PDSCH的下行控制信息(Downlink Control Information，DCI)可以通过不同的控制资源集(Control Resource Set，CORESET)来承载，即网络侧配置多个CORESET，每个TRP采用各自的CORESET进行调度，即可以通过CORESET来区分不同的TRP。例如，网络设备可以为每个CORESET配置一个CORESET组索引，不同的索引对应不同的TRP。终端反馈CSI时，需要分别反馈每个TRP各自对应的CSI。所述CSI包含秩指示(Rank Indication，RI)，预编码矩阵指示(Precoding Matrix Indicator，PMI)，信道质量指示(Channel Quantity Indicator，CQI)等内容，可以用于各自TRP进行下行传输的调度。
为便于更好的理解本申请实施例，对本申请相关的下行CSI上报进行说明。
为了网络设备能够进行合理的调度，终端需要反馈下行信道状态信息CSI，以让基站确定传输层数、预编码矩阵、发送波束、调制编码方式等终端的调度信息。具体的，终端的CSI上报基于网络设备指示的CSI上报配置进行，终端上报CSI所用的上行资源以及进行CSI测量所用的下行参考信号和测量子带都是通过CSI上报配置指示，CSI上报配置(CSI-ReportConfig)可以如图3所示。其中，用于CSI测量的资源包含两种类型的资源：信道测量资源(Channel Measurement Resource，CMR)和干扰测量资源(Interference Measurement Resource，IMR)。具体的，CMR可以是若干个非零功率信道状态信息参考信号(Non-Zero Power Channel State Information-Reference Signal，NZP-CSI-RS)或者同步信号块(Synchronization Signal Block，SSB)，干扰测量资源可以是信道状态信息干扰测量(Channel State Information Interference Measurement，CSI-IM)和/或NZP-CSI-RS。同时，基站可以通过CSI上报配置指示终端需要测量哪些子带上的CSI，终端只需要测量这些子带上的信号和干扰，并反馈这些子带对应的CSI。每个CSI上报配置对应一个CSI上报，每个CSI上报可以包含CRI，RI，PMI，CQI等不同的信息。具体的，CSI中包含哪些内容/信息通过CSI上报配置中的上报量信息(reportQuantity)来确定。
需要说明的是，SSB也可以称为同步信号/物理广播信道块(synchronization signal/physical broadcast channel block，SS/PBCH block)。
现阶段，终端针对每个CSI上报配置上报一个CSI，所述CSI基于网络配置的信道测量资源和干扰测量资源计算得到，用于获得一个TRP的信道信息。例如，终端可以用CSI上报配置1得到TRP1单独的CSI，用CSI上报配置2得到TRP2单独的CSI。在基于多DCI的多TRP传输方案种，两个TRP独立进行同一个终端设备的PDSCH调度，相应的PDSCH物理资源可以是完全重叠，部分重叠或者不重叠的。在不同的资源重叠情况下，由于干扰的不同相应的CSI也会不同。现有的CSI上报方案无法支持上报不同资源重叠情况下的CSI，网络设备得到的CSI并不一定是当前调度情况下的最优CSI，从会影响多TRP传输的性能。
基于上述问题，本申请提出了一种配置资源重叠类型信息的方案，可以通过资源重叠类型信息指示终端设备测量不同PDSCH资源重叠假设下的CSI，从而进行不同资源重叠情况下的PDSCH灵活调度，支持基于多DCI的多TRP同时传输。网络设备在获得不同资源重叠类型对应的CSI后，可以根据当前的调度结果，采用相应的CSI用于所调度的PDSCH，从而获得更高的吞吐量。
以下通过具体实施例详述本申请的技术方案。
图4是根据本申请实施例的无线通信的方法200的示意性流程图，如图4所示，该方法200可以包括如下内容中的至少部分内容：
S210，网络设备向终端设备发送第一CSI上报配置，该第一CSI上报配置中至少包括资源重叠类型信息；
S220，该终端设备接收该第一CSI上报配置；
S230，该终端设备根据该资源重叠类型信息进行CSI测量。
在本申请实施例中，资源重叠是指PDSCH的资源重叠。CSI测量的时候需要有一个传输假设(与网络设备调度的PDSCH对应)，可以假设PDSCH是重叠或者不重叠，相应的CSI测量方法不同，在CSI测量之后，可以将CSI测量结果上报给网络设备，CSI上报是用于PDSCH传输的。
也即，在本申请实施例中，该资源重叠类型信息用于指示终端设备根据所指示的资源重叠类型(OverlappingType)进行CSI测量。
在一些实施例中，该资源重叠类型信息用于指示不重叠、部分重叠、完全重叠中的至少一种。
在一些实施例中，该资源重叠类型信息用于指示不重叠、重叠中的至少一种。
在一些实施例中，该第一CSI上报配置中的资源重叠类型信息与第二CSI上报配置中的资源重叠类型信息相同；其中，该第二CSI上报配置是与该第一CSI上报配置关联的CSI上报配置。
该第一CSI上报配置与该第二CSI上报配置的关联关系可以预先通过高层信令通知给终端设备的，即该第一CSI上报配置和该第二CSI上报配置的关联关系是通过高层信令预先配置的。
在一些实施例中，该第一CSI上报配置和该第二CSI上报配置的关联关系是通过该第一CSI上报配置指示的。例如，在该第一CSI上报配置中指示关联的该第二CSI上报配置的配置标识(ID)。
在一些实施例中，与该第一CSI上报配置关联的CSI上报配置可以是一个或多个，此外，与该第一CSI上报配置关联的CSI上报配置可以通过该第一CSI上报配置中携带的信息指示。
在一些实施例中，在该资源重叠类型信息指示不同的资源重叠类型的情况下，该终端设备进行CSI测量所用的干扰测量资源或者干扰测量假设不同。
需要说明的是，该终端设备进行CSI测量所用的干扰测量假设，例如可以是：干扰测量所假设的波束、天线面板(panel)、预编码器(precoder)中的一种或多种。
作为实施例1，该资源重叠类型信息用于指示不重叠、部分重叠、完全重叠中的至少一种。
在实施例1的一些实现方式中，在该资源重叠类型信息指示不重叠的情况下，上述S230具体包括：
该终端设备根据该第一CSI上报配置中指示的第一CMR和第一IMR进行CSI测量。
也就是说，在资源重叠类型信息指示不重叠的情况下，终端设备可以按照第一CSI上报配置中指示的第一CMR和第一IMR进行CSI测量及CSI上报，不需要考虑来自另外的TRP的干扰。
在实施例1的一些实现方式中，在该资源重叠类型信息指示部分重叠的情况下，上述S230具体包括：
该终端设备在第一子带上将第二CMR作为干扰测量资源进行CSI测量，以及在第二子带上不将第二CMR作为干扰测量资源进行CSI测量；
其中，该第一子带为该第一CSI上报配置与第二CSI上报配置中均指示的上报子带，该第二子带为该第一CSI上报配置中指示但第二CSI上报配置中没有指示的上报子带，该第二CMR为第二CSI上报配置中指示的CMR，该第二CSI上报配置是与该第一CSI 上报配置关联的CSI上报配置。
也即，在资源重叠类型信息指示部分重叠的情况下，在关联的两个CSI上报配置中重叠的子带上考虑另一个TRP的干扰，非重叠的子带上不考虑另一个TRP的干扰。
例如，假设第一CSI上报配置中指示第一CMR作为信道测量资源，第一IMR作为干扰测量资源，指示的上报子带(Band)为{Band0,Band1,Band6,Band7}；与第一CSI上报配置关联的第二CSI上报配置中指示第二CMR作为信道测量资源，第二IMR作为干扰测量资源，指示的上报子带为{Band0,Band1,Band2,Band3}。此时，第一子带为在第一CSI上报配置与第二CSI上报配置中都指示的上报子带，即Band0和Band1；第二子带为第一CSI上报配置指示但第二CSI上报配置中没有指示的上报子带，即Band6和Band7。
终端设备在第一子带(即Band0和Band1)上将第二CMR作为干扰测量资源进行CSI测量，即终端设备需要在第二CMR和第一IMR上都进行干扰测量，并基于测量的干扰进行第一CSI上报配置的CSI计算。终端设备在第二子带(Band6和Band7)上不将第二CMR作为干扰测量资源，即终端设备在第二子带上只基于第一CMR和第一IMR进行CSI测量。
在一些实施例中，在资源重叠类型信息指示部分重叠的情况下，该第一CSI上报配置与该第二CSI上报配置中指示的上报子带不完全相同。
在实施例1的一些实现方式中，如果第一CSI上报配置与第二CSI上报配置中指示的上报子带完全相同，则终端设备可以在所有上报子带上将第二CSI上报配置中指示的第二CMR作为干扰测量资源进行CSI测量。
在实施例1的一些实现方式中，如果第一CSI上报配置与第二CSI上报配置中指示的上报子带完全不同，则终端设备可以在所有上报子带上都不将第二CSI上报配置中指示的第二CMR作为干扰测量资源进行CSI测量。
在实施例1的一些实现方式中，在该资源重叠类型信息指示完全重叠的情况下，上述S230具体包括：
该终端设备在该第一CSI上报配置中指示的全部子带上将第二CMR作为干扰测量资源进行CSI测量；
其中，该第二CMR为第二CSI上报配置中指示的CMR，该第二CSI上报配置是与该第一CSI上报配置关联的CSI上报配置。
具体例如，在资源重叠类型信息指示完全重叠的情况下，终端设备在第一CSI上报配置指示的所有上报子带上，在第二CSI上报配置中指示的第二CMR和第一CSI上报配置中指示的第一IMR上都进行干扰测量，并基于测量的干扰进行第一CSI上报配置的CSI计算。
在一些实施例中，在资源重叠类型信息指示完全重叠的情况下，该第一CSI上报配置与该第二CSI上报配置中指示的上报子带完全相同。
在实施例1的一些实现方式中，在资源重叠类型信息指示完全重叠的情况下，如果第一CSI上报配置与第二CSI上报配置中指示的上报子带不完全相同，终端设备只上报其中重叠的子带上的CSI，不上报非重叠子带上的CSI。
在实施例1中，例如，如图5所示，在资源重叠类型信息指示完全重叠的情况下，在第一非零功率CSI-RS(即第一CSI上报配置中指示的CMR)上进行信道测量，以及在第一CSI-IM(即第一CSI上报配置中指示的IMR)和第二非零功率CSI-RS(即第二CSI上报配置中指示的CMR)上进行干扰测量。在资源重叠类型信息指示部分重叠的情况下，对于重叠子带，在第一非零功率CSI-RS(即第一CSI上报配置中指示的CMR)上进行信道测量，以及在第一CSI-IM(即第一CSI上报配置中指示的IMR)和第二非零功率CSI-RS(即第二CSI上报配置中指示的CMR)上进行干扰测量；对于非重叠子带，在第一非零功率CSI-RS(即第一CSI上报配置中指示的CMR)上进行信道测量，以及 在第一CSI-IM(即第一CSI上报配置中指示的IMR)上进行干扰测量。在资源重叠类型信息指示不重叠的情况下，在第一非零功率CSI-RS(即第一CSI上报配置中指示的CMR)上进行信道测量，以及在第一CSI-IM(即第一CSI上报配置中指示的IMR)上进行干扰测量。
在实施例1的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备根据该多个资源重叠类型分别进行CSI测量，且该多个资源重叠类型的CSI测量基于相同的CMR和/或不同的IMR。
例如，当资源重叠类型信息指示不重叠和完全重叠时，两种资源重叠类型基于相同的第一CMR进行信道测量，但进行干扰测量时，完全重叠的情况下需要额外考虑来自另一个TRP(CSI上报配置)的干扰。
在实施例1的一些实现方式中，该终端设备上报该第一CSI上报配置对应的CSI，其中，该第一CSI上报配置对应的CSI中包含至少一个资源重叠类型对应的CSI。
在实施例1的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备将该多个资源重叠类型对应的CSI按照该多个资源重叠类型的配置顺序进行级联后，在同一个CSI上报中反馈。
例如，当资源重叠类型信息指示“完全重叠”和“不重叠”时，对应的CSI分别为CSI0和CSI1，则终端将这两个CSI按照{CSI0，CSI1}的顺序进行级联后在同一个CSI中上报。
对于网络侧，网络设备在获得不同资源重叠类型对应的CSI后，可以根据当前的调度结果(不同TRP的PDSCH是否存在资源重叠)，采用相应的CSI用于所调度的PDSCH，从而获得更高的吞吐量。
在实施例1的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备从该多个资源重叠类型对应的CSI中选择部分资源重叠类型对应的CSI进行CSI上报。
在一些实现方式中，该终端设备可以向网络设备发送第一指示信息，其中，该第一指示信息用于指示该多个资源重叠类型中该终端设备所选择的资源重叠类型，或者，该第一指示信息用于指示该多个资源重叠类型中该终端设备所选择的资源重叠类型对应的CSI的标识。
需要说明的是，该第一指示信息可以与该第一CSI上报配置对应的CSI一起上报，也可以单独上报，本申请对此并不限定。
例如，假设资源重叠类型信息指示“完全重叠”“部分重叠”和“不重叠”，终端设备从三种资源重叠类型各自对应的CSI中，选择一种资源重叠类型对应的CSI进行上报，并用2比特信息指示所选择的资源重叠类型。这2比特中不同的状态对应不同的资源重叠类型。
具体的，终端设备可以根据当前的信道状态，推荐最优的资源重叠类型并将相应的CSI上报给网络设备，从而网络设备可以采用对应的调度策略以达到推荐的重叠状态，并采用反馈的CSI达到更高的吞吐量。
在实施例1的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型，且该第一CSI上报配置对应的CSI中的部分CSI需要丢弃的情况下，该终端设备按照该多个资源重叠类型的配置顺序依次进行丢弃，或者，该终端设备按照与网络设备约定好的丢弃顺序进行丢弃。
例如，当承载第一CSI上报配置对应的CSI上报的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)/物理上行控制信道(Physical Uplink Control Channel，PUCCH)的码率超过一定门限时，需要丢弃其中部分的CSI，从而保证丢弃后的码率不会超过该门限。假设资源重叠类型信息指示“部分重叠”和“不重叠”(部分重叠的配置顺序在前)，对应的CSI分别为CSI0和CSI1，则在丢弃CSI时，可以先丢弃配置顺序在后的 上报量信息对应的CSI(即CSI1)，在需要时再丢弃配置顺序在前的上报量信息对应的CSI(即CSI0)，直到码率满足门限。
在一些实现方式中，该与网络设备约定好的丢弃顺序包括：
先丢弃资源重叠类型为部分重叠对应的CSI，接着丢弃资源重叠类型为完全重叠对应的CSI，再丢弃资源重叠类型为不重叠对应的CSI。
在另一种实现方式中，该与网络设备约定好的丢弃顺序包括：
先丢弃资源重叠类型为完全重叠对应的CSI，接着丢弃资源重叠类型为部分重叠对应的CSI，再丢弃资源重叠类型为不重叠对应的CSI。以此类推。
作为实施例2，该资源重叠类型信息用于指示不重叠、重叠中的至少一种。
在实施例2的一些实现方式中，在该资源重叠类型信息指示不重叠的情况下，上述S230具体包括：
该终端设备根据该第一CSI上报配置中指示的第一CMR和第一IMR进行CSI测量。
也就是说，在资源重叠类型信息指示不重叠的情况下，终端设备可以按照第一CSI上报配置中指示的第一CMR和第一IMR进行CSI测量及CSI上报，不需要考虑来自另外的TRP的干扰。
在实施例2的一些实现方式中，在该资源重叠类型信息指示重叠的情况下，上述S230具体包括：
该终端设备在该第一CSI上报配置中指示的全部子带上将第二CMR作为干扰测量资源进行CSI测量；
其中，该第二CMR为第二CSI上报配置中指示的CMR，该第二CSI上报配置是与该第一CSI上报配置关联的CSI上报配置。
具体例如，终端设备在第一CSI上报配置指示的所有上报子带上，在第二CSI上报配置中指示的第二CMR和第一CSI上报配置中指示的第一IMR上都进行干扰测量，并基于测量的干扰进行第一CSI上报配置的CSI计算。
在实施例2的一些实现方式中，在该资源重叠类型信息指示重叠的情况下，上述S230具体包括：
该终端设备在第一子带上将第二CMR作为干扰测量资源进行CSI测量，以及在第二子带上不将第二CMR作为干扰测量资源进行CSI测量；
其中，该第一子带为该第一CSI上报配置与第二CSI上报配置中均指示的上报子带，该第二子带为该第一CSI上报配置中指示但第二CSI上报配置中没有指示的上报子带，该第二CMR为第二CSI上报配置中指示的CMR，该第二CSI上报配置是与该第一CSI上报配置关联的CSI上报配置。
在一些实现方式中，如果第一CSI上报配置和第二CSI上报配置中的上报子带不完全相同，该终端设备在第一子带上将第二CMR作为干扰测量资源进行CSI测量，以及在第二子带上不将第二CMR作为干扰测量资源进行CSI测量；
其中，该第一子带为该第一CSI上报配置与第二CSI上报配置中均指示的上报子带，该第二子带为该第一CSI上报配置中指示但第二CSI上报配置中没有指示的上报子带，该第二CMR为第二CSI上报配置中指示的CMR，该第二CSI上报配置是与该第一CSI上报配置关联的CSI上报配置。
在一些实现方式中，如果第一CSI上报配置和第二CSI上报配置中的上报子带相同，则终端设备在所有的子带上将第二CSI上报配置中指示的第二CMR作为干扰测量资源进行CSI测量，即此时只有第一子带，没有第二子带。
例如，假设第一CSI上报配置中指示第一CMR作为信道测量资源，第一IMR作为干扰测量资源，指示的上报子带为{Band0,Band1,Band2,Band3}；与第一CSI上报配置关联的第二CSI上报配置中指示第二CMR作为信道测量资源，第二IMR作为干扰测量资源，指示的上报子带为{Band2,Band3,Band4,Band5}。此时第一子带为Band2和Band3， 第二子带为Band0和Band1。终端设备在第一子带(即Band2和Band3)中在第二CMR和第一IMR上都进行干扰测量，并基于测量的干扰进行第一CSI上报配置的CSI计算。终端设备在第二子带(Band0和Band1)上不将第二CMR作为干扰测量资源，即终端只基于第一CMR和第一IMR进行CSI测量。如果此时第一和第二CSI上报配置中的上报子带均为{Band0,Band1,Band2,Band3}，则终端在所有子带上都将第二CMR作为干扰测量资源。
在实施例2的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备根据该多个资源重叠类型分别进行CSI测量，且该多个资源重叠类型的CSI测量基于相同的CMR和/或不同的IMR。
在实施例2的一些实现方式中，该终端设备上报该第一CSI上报配置对应的CSI，其中，该第一CSI上报配置对应的CSI中包含至少一个资源重叠类型对应的CSI。
在实施例2的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备将该多个资源重叠类型对应的CSI按照该多个资源重叠类型的配置顺序进行级联后，在同一个CSI上报中反馈。
例如，当资源重叠类型信息指示“重叠”和“不重叠”时，对应的CSI分别为CSI0和CSI1，则终端设备将这两个CSI按照{CSI1，CSI0}的顺序(配置在后则级联顺序在前)进行级联后在同一个CSI中上报。
在实施例2的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型的情况下，该终端设备从该多个资源重叠类型对应的CSI中选择部分资源重叠类型对应的CSI进行CSI上报。
例如，当资源重叠类型信息指示两个资源重叠类型时，终端设备从两个资源重叠类型对应的CSI中，选择一个资源重叠类型对应的CSI进行CSI上报。
在一些实现方式中，该终端设备可以向网络设备发送第一指示信息，其中，该第一指示信息用于指示该多个资源重叠类型中该终端设备所选择的资源重叠类型，或者，该第一指示信息用于指示该多个资源重叠类型中该终端设备所选择的资源重叠类型对应的CSI的标识。
需要说明的是，该第一指示信息可以与该第一CSI上报配置对应的CSI一起上报，也可以单独上报，本申请对此并不限定。
例如，终端设备上报所选择的资源重叠类型的指示信息，或者所选择的资源重叠类型对应的CSI的指示信息。具体的，可以采用1比特的信令来指示所选择的资源重叠类型或者所选择的资源重叠类型对应的CSI。
在实施例2的一些实现方式中，在该资源重叠类型信息指示多个资源重叠类型，且该第一CSI上报配置对应的CSI中的部分CSI需要丢弃的情况下，该终端设备按照该多个资源重叠类型的配置顺序依次进行丢弃，或者，该终端设备按照与网络设备约定好的丢弃顺序进行丢弃。
例如，当承载第一CSI上报配置对应的CSI上报的PUSCH/PUCCH的码率超过一定门限时，需要丢弃其中部分的CSI，从而保证丢弃后的码率不会超过该门限。假设资源重叠类型信息指示“不重叠”和“重叠”(不重叠的配置顺序在前)，对应的CSI分别为CSI0和CSI1，则在丢弃CSI时，可以先丢弃配置顺序在前的上报量信息对应的CSI(即CSI0)，在需要时再丢弃配置顺序在前的上报量信息对应的CSI(即CSI1)，直到码率满足门限。
在一些实现方式中，该与网络设备约定好的丢弃顺序包括：
先丢弃资源重叠类型为重叠对应的CSI，再丢弃资源重叠类型为不重叠对应的CSI。
因此，在本申请实施例中，网络设备可以通过资源重叠类型信息指示终端设备测量不同PDSCH资源重叠假设下的CSI，从而进行不同资源重叠情况下的PDSCH灵活调度，支持基于多DCI的多TRP同时传输。此外，网络设备在获得不同资源重叠类型对应的 CSI后，可以根据当前的调度结果，采用相应的CSI用于所调度的PDSCH，从而获得更高的吞吐量。
