Description

用于传输信道状态信息的方法及设备 技术领域
本申请涉及通信领域，并且更具体地，涉及一种用于传输信道状态信息的方法及设备。
背景技术
通常，为了实现更好的调度，终端设备需要向网络设备上报信道状态信息(channel state information，CSI)，然后网络设备可以根据终端设备上报的CSI进行调度处理，例如选择信道质量比较好的下行信道进行下行传输。
终端设备在上报CSI时，由于无法确定与该CSI关联的控制资源集(ControlResourceSet，CORESET)组索引，也就不知道将该CSI传输到哪个传输点/发送接收点(Transmission/reception point，TRP)，因此，终端设备无法确定该CSI和其他上行信息能否复用传输。
发明内容
本申请提供一种用于传输信道状态信息的方法及设备，能够有效地进行CSI的传输。
第一方面，提供了一种用于传输信道状态信息的方法，包括：终端设备根据信道状态信息CSI对应的CSI上报配置，确定与所述CSI关联的控制资源集CORESET组索引；终端设备根据所述CORESET组索引，确定所述CSI能否与其他上行信息进行复用传输。
第二方面，提供了一种终端设备，用于执行上述第一方面或其各实现方式中的方法。
具体地，该终端设备包括用于执行上述第一方面或其各实现方式中的方法的功能模块。
第三方面，提供了一种终端设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述第一方面或其各实现方式中的方法。
第四方面，提供了一种装置，用于实现上述第一方面或其各实现方式中的方法。
具体地，该装置包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该装置的设备执行如上述第一方面或其各实现方式中的方法。
第五方面，提供了一种计算机可读存储介质，用于存储计算机程序，该计算机程序使得计算机执行上述第一方面或其各实现方式中的方法。
第六方面，提供了一种计算机程序，当其在计算机上运行时，使得计算机执行上述第一方面或其各实现方式中的方法。
基于上述技术方案，将CSI上报配置中包含的配置信息与CORESET组索引相关联，不同的CORESET组索引对应不同的TRP，利用CORESET组索引就可以区分CSI对应的TRP，因此终端设备可以确定将该CSI传输到哪个TRP，从而终端设备能够该CSI是否可以与其他上行信息复用传输。

应理解，本文中术语“系统”和“网络”在本文中常被可互换使用。
在NR系统中引入了基于多个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设备的物理下行共享信道(physical downlink shared channel，PDSCH)传输，也可以采用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。终端设备需要支持同时接收来自不同TRP的PDCCH和PDSCH。终端设备反馈正确应答/否定应答(acknowledgement/negative acknowledgement，ACK/NACK)和信道状态信息(channel status 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所示)，也可以合并上报给一个TRP(如图3所示)。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CORESET来承载，即网络侧可以配置多个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(CSI associated with CORESET index)，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。其中，CSI中包括的内容例如可以有秩指示(rank indication，RI)、预编码矩阵指示(precoding matrix indicator，PMI)、信道质量指示(channel quality indicator，CQI)等内容，可以用于各自TRP进行下行传输的调度。
对于采用单个PDCCH调度的多TRP下行传输，如图4所示。同一个DCI可以调度来自不同TRP的多个传输层。其中，来自不同TRP的传输层采用不同CDM组中的DMRS端口，且采用不同的传输配置指示(transmission configuration indicator，TCI)状态。网络设备需要在一个DCI中指示来自不同的码分复用(code division multiplexing，CDM)组的解调参考信号(demodulation reference signal，DMRS)端口，以及不同CDM组所分别对应的TCI状态，从而支持不同的DMRS端口采用不同的波束来传输。这种情况下，混合自动重传请求(hybrid automatic repeat request，HARQ)-ACK反馈和CSI上报可以重用现有协议中的机制。这种方案只能用于理想backhaul的场景。
在NR中，网络侧可以采用模拟波束来传输下行PDSCH，如图5所示，图5所示的过程是以信道状态信息参考信号(channel state information reference signal，CSI-RS)为例进行说明的。在进行模拟波束赋形之前，网络侧需要通过下行波束管理过程来确定所用的波束，下行波束管理可以基于CSI-RS或者同步信号块(synchronzation signal block，SSB)进行。具体的，网络侧发送用于波束管理的多个SSB或者多个CSI-RS资源，终端基于这些SSB或CSI-RS资源进行测量，选择其中接收质量最好的若干个SSB或者CSI-RS资源，并将相应的SSB索引或CSI-RS资源索引以及相应的参考信号接收功率(reference signal receiving power，RSRP)上报给网络侧。网络侧根据终端的上报得到一个最优的SSB或CSI-RS资源，将其所用的发送波束确定为下行传输所用的发送波束，从而用于传输下行控制信 道或者数据信道。网络侧在传输下行控制信道或数据信道之前，会通过TCI状态将对应的准共址(quasi-co-located，QCL)参考信号指示给终端，从而终端可以采用之前接收所述QCL参考信号所用的接收波束，来接收对应的下行控制信道或数据信道。
在传统方案中，针对非周期性CSI上报，终端设备可以根据触发该非周期性CSI上报的DCI所在的CORESET的CORESET组索引，确定该非周期性CSI上报关联哪个TRP，然后终端设备就可以将该非周期性CSI发送给该TRP，其中，不同的CORESET组索引可以对应不同的TRP。但是对于周期性和半持续性CSI，终端设备不知道与周期性和半持续性CSI关联的CORESET组索引，也就无法知道将该CSI发送给哪个TRP。
本申请实施例提供一种用于传输CSI的方法，终端设备可以根据该方法，确定CSI对应的CORESET组索引，然后根据该CORESET组索引进行CSI的传输。如图6所示，该方法包括步骤S610～S620。
S610、终端设备根据CSI对应的CSI上报配置，确定与所述CSI关联的CORESET组索引。
S620、终端设备根据所述CORESET组索引，确定该CSI能否与其他上行信息进行复用传输。
本申请实施例，通过CSI上报配置中包含的配置信息确定出与CSI关联的CORESET组索引，不同的CORESET组索引对应不同的TRP，利用CORESET组索引就可以区分CSI对应的TRP，不需要增加额外的信令开销。然后终端设备可以将该CSI发送给确定的CORESET组索引对应的TRP。
CSI上报配置可用于指示终端设备上报CSI所需要的信息。例如，可以包括测量参数、门限值、资源信息、CSI上报方式等。CSI上报配置可以是通过高层信令发送给终端设备的。CSI上报配置可以承载在无线资源控制(radio resource control，RRC)参数中。
终端设备可以根据网络设备发送的高层信令确定CSI对应的CSI上报配置。例如，网络设备可以向终端设备配置多个CSI上报配置，终端设备可以通过高层信令确定不同CSI上报配置对应的CSI。
对于周期性和半持续性的CSI上报，每个CSI上报可以对应一个CSI上报配置。其中，半持续性CSI也可以称为半静态CSI。
在本申请实施例中，CORESET组索引为网络设备通过高层信令为每个CORESET分别配置的索引值，索引值相同的CORESET为一个CORESET组。
例如，网络设备可以在用于配置CORESET的RRC配置参数中，例如RRC参数控制资源集(ControlResourceSet)，为每个CORESET分别配置一个索引，称为CORESET组索引(名称不限于此)。网络设备为不同CORESET配置的索引可以相同，也可以不同。
本申请实施例中的CORESET组索引可用于确定HARQ-ACK码本(codebook)，即配置不同的CORESET组索引的CORESET调度的PDSCH的HARQ-ACK可以采用独立的HARQ-ACK码本。
本申请实施例对确定与所述CSI关联的CORESET组索引的方式不做具体限定。例如，终端设备可以根据以下信息中的至少一种：CSI上报配置的标识(identity，ID)信息、CSI上报配置所指示的用于传输CSI的物理上行控制信道(physical uplink control channel，PUCCH)资源、CSI上报配置所指示的用于测量CSI的测量资源、CSI上报配置所指示的 上报内容，确定与CSI相关联的CORESET组索引。
终端设备可以根据上述信息中的一种信息确定与CSI相关联的CORESET组索引，也可以将上述信息信息相互结合，即根据上述信息中的多种信息确定与CSI相关联的CORESET组索引。
下面以终端设备根据CSI上报配置的ID信息，确定与CSI相关联的CORESET组索引为例进行描述。
这里的ID信息为网络设备指示的用于标识每个CSI上报配置的ID，例如，网络设备通过RRC信令指示的CSI-ReportConfigId。
方式1、如果该ID小于预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第一索引；如果该ID大于或等于预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第二索引。其中，第一索引与第二索引不同。或者，如果该ID小于或等于预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第一索引；如果该ID大于预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第二索引
该预设值可以是协议中预定义的，也可以是网络设备发送给终端设备的，或者也可以是预配置在终端设备中的。
本申请实施例对CORESET组索引的取值个数不做具体限定，CORESET组索引的取值可以有两个，可以多于两个。
如果CORESET组索引有两个值，则可以设置一个预设值；如果CORESET组索引有三个值，则可以设置两个预设值，以此类推。例如，如果该ID小于第一预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第一索引；如果该ID大于或等于第一预设值且小于第二预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第二索引；如果该ID大于或等于第三预设值，则终端设备可以确定与CSI相关联的CORESET组索引为第三索引。
以CORESET组索引有两个值为例，该预设值可以为M/k，其中，M为终端设备可以被配置的CSI上报配置的最大数量，k＞1。这两个值均可以由终端设备与网络设备预先约定好。
本申请实施例对M、k的取值不做具体限定。例如，M的取值可以为48。k的取值可以为1.5或2或3等。
本申请实施例对CORESET组索引的取值不做具体限定。CORESET组索引的取值例如可以为0或1，当然，CORESET组索引的取值也可以是0和1之外的其他值。
以CORESET组索引的取值为0或1为例，则第一索引可以为1，第二索引为0；或者，第一索引为0，第一索引为1。
举例说明，如果ID小于M/k，则终端设备可以确定与CSI相关联的CORESET组索引为0；如果ID大于或等于M/k，则终端设备可以确定与CSI相关联的CORESET组索引为1。或者，如果ID小于M/k，则终端设备可以确定与CSI相关联的CORESET组索引为1；如果ID大于或等于M/k，则终端设备可以确定与CSI相关联的CORESET组索引为0。
下面以M＝48，k＝2为例，对本申请实施例的具体实施方式进行描述，如图7所示。
当CSI测量配置的ID的取值在0～23之间时，与CSI相关联的CORESET组索引为0；当CSI测量配置的ID的取值在24～47之间时，与CSI相关联的CORESET组索引为1。
方式2、如果ID为偶数，则终端设备确定与CSI相关联的CORESET组索引为第一索引；如果ID为奇数，则终端设备确定与CSI相关联的CORESET组索引为第二索引。或者，如果ID为偶数，则终端设备确定与CSI相关联的CORESET组索引为第二索引；如果ID为奇数，则终端设备确定与CSI相关联的CORESET组索引为第一索引。
关于第一索引和第二索引的描述可以参照上文的描述，下文将不再重复。
举例说明，如果ID为偶数，则终端设备可以确定与CSI相关联的CORESET组索引为0；如果ID为奇数，则终端设备可以确定与CSI相关联的CORESET组索引为1，如图8所示。或者，如果ID为偶数，则终端设备可以确定与CSI相关联的CORESET组索引为1；如果ID为奇数，则终端设备可以确定与CSI相关联的CORESET组索引为0。
作为另一种实现方式，终端设备也可以根据ID取模后的值，确定与CSI相关联的CORESET组索引。例如，如果ID对X取模后的值为0，则终端设备确定与CSI相关联的CORESET组索引为0，否则，终端设备确定与CSI相关联的CORESET组索引为1，其中，X为大于1的整数。
如果CORESET组索引有多个值，则终端设备可以根据ID取模后的值的不同，确定与CSI相关联的CORESET组索引。例如，如果ID对X取模后的值为0，则终端设备确定与CSI相关联的CORESET组索引为0；如果ID对X取模后的值为1，则终端设备确定与CSI相关联的CORESET组索引为1；如果ID对X取模后的值为2，则终端设备确定与CSI相关联的CORESET组索引为2。
通过上述实现方式，网络设备可以通过CSI上报配置的ID信息对CSI进行分组，不同组的CSI对应不同的TRP，从而可以在终端侧区分发给不同TRP的CSI。
下面以终端设备根据CSI上报配置所指示的用于传输CSI的PUCCH资源，确定与CSI相关联的CORESET组索引为例进行描述。
终端设备在发送CSI时，可以在CSI上报配置所指示的PUCCH资源上发送该CSI。该PUCCH资源可以包括时域资源和频域资源。
方式1、如果该PUCCH资源包含在第一PUCCH资源集合中，则终端设备可以确定与CSI相关联的CORESET组索引为第一索引；如果该PUCCH资源没有包含在第一PUCCH资源集合中，则终端设备可以确定与CSI相关联的CORESET组索引为第二索引。例如，如果该PUCCH资源包含在第二PUCCH资源集合中，则终端设备可以确定与CSI相关联的CORESET组索引为第二索引。
其中，该第一PUCCH资源集合为特定的PUCCH资源集合。该第一PUCCH资源集合可以是网络设备指定给终端设备的PUCCH资源集合，或者也可以是协议中规定的PUCCH资源集合，或者也可以是预配置在终端设备中的PUCCH资源集合。
网络设备可以在一个时隙内配置占用不同时域资源的多个PUCCH资源集合，这些PUCCH资源集合可以用于不同TRP的PUCCH传输。该第一PUCCH资源集合可以是该多个PUCCH资源集合中的任意一个或多个PUCCH资源集合。例如，该第一PUCCH资源可以为一个时隙内配置的占用不同时域资源的多个PUCCH资源集合的第一个PUCCH资源集合。
当然，第一PUCCH资源集合也不局限于为一个时隙内包含的多个PUCCH资源集合中的第一个PUCCH资源集合，也可以为一个时隙内包含的多个PUCCH资源集合中的前 n个PUCCH资源集合，其中，n≥2。
网络设备在向终端设备配置一个时隙内的不同PUCCH资源集合时，还可以为终端设备预配置不同PUCCH资源集合与CORESET组索引的对应关系。终端设备可以根据网络设备预配置的PUCCH资源集合与CORESET组索引的对应关系，以及所述PUCCH资源所在的PUCCH资源集合，确定与该CSI关联的CORESET组索引。
例如，终端设备确定用于传输CSI的PUCCH资源属于第一PUCCH资源集合，且网络设备预配置的第一PUCCH资源集合对应于CORESET组索引0，则终端设备可以确定与该CSI对应的CORESET组索引为索引0。又例如，终端设备确定用于传输CSI的PUCCH资源属于第二PUCCH资源集合，且网络设备预配置的第二PUCCH资源集合对应于CORESET组索引1，则终端设备可以确定与该CSI对应的CORESET组索引为索引1。
作为优选的实现方式，该第一PUCCH资源集合可以为一个时隙内占用不同时域资源的多个PUCCH资源集合中最靠前的PUCCH资源集合。一个时隙内占用不同时域资源的多个PUCCH资源集合可以指一个时隙内占用不同时域资源的所有PUCCH资源集合。
如图9所示，网络设备可以在一个时隙中配置占用不同正交频分复用(orthogonal frequency division multiplexing，OFDM)符号的2个PUCCH资源集合，其中时域位置最靠前的PUCCH资源集合1为第一PUCCH资源集合。如果用于承载CSI的PUCCH资源属于PUCCH资源集合1，则终端设备可以确定与CSI相关联的CORESET组索引为0；如果用于承载CSI的PUCCH资源属于PUCCH资源集合2，则终端设备可以确定与CSI相关联的CORESET组索引为1。或者，如果用于承载CSI的PUCCH资源属于PUCCH资源集合1，则终端设备可以确定与CSI相关联的CORESET组索引为1；如果用于承载CSI的PUCCH资源属于PUCCH资源集合2，则终端设备可以确定与CSI相关联的CORESET组索引为0。
基于该方式，网络设备可以通过用于传输PUCCH的时域资源的不同对CSI进行分组，不同组的CSI对应不同的TRP，从而在终端侧可以区分来自不同TRP的CSI。
方式2、如果在该PUCCH资源所在的至少部分时域资源单元上，终端设备还需要发送其他上行信息，则终端设备可以确定与CSI关联的CORESET组索引和与其他上行信息关联的CORESET组索引相同。
该其他上行信息例如可以为以下中的至少一种：HARQ-ACK、调度请求(scheduling request，SR)、CSI和PUSCH承载的上行数据。
时域资源单元可以为以下中的至少一种：时隙、子时隙和OFDM符号。
具体地，如果在PUCCH资源所在的OFDM符号上，终端设备需要同时发送其他上行控制信息(如通过另一个PUCCH资源发送HARQ-ACK或通过PUSCH发送非周期性CSI)或者上行数据，则终端设备可以认为与该CSI关联的CORESET组索引和与需要发送的上行控制信息或上行数据关联的CORESET组索引相同。例如，如果与同时发送的上行控制信息或上行数据关联的CORESET组索引为0，则与该CSI关联的CORESET组索引也为0。
终端设备假设同时发送的上行信息都关联相同的CORESET组索引，这样就不需要为每个上行信息都配置一个关联的CORESET组索引，能够节省信令开销。
下面以终端设备根据CSI上报配置所指示的用于测量CSI的测量资源，确定与CSI相 关联的CORESET组索引为例进行描述。
例如，终端设备可以根据该测量资源中是否包括SSB，确定与CSI相关联的CORESET组索引。如果测量资源中包括SSB，则终端设备可以确定与CSI相关联的CORESET组索引为第一索引。
举例说明，如果测量资源中包括SSB索引的配置信息，则终端设备需要基于该SSB进行CSI的相关测量，此时终端设备可以确定与该CSI关联的CORESET组索引为0。
当然，该方式也可以与其他方式相结合。例如，如果测量资源中包括SSB，则终端设备可以确定与该CSI关联的CORESET组索引为0；如果测量资源中没有包括SSB，则终端设备可以根据其他方式(如上文描述的方式1或方式2)确定与该CSI关联的CORESET组索引。又例如，如果测量资源中包括SSB，则终端设备期望根据其他方式确定的与CSI关联的CORESET组索引的取值也为0。
该SSB可用于终端设备对信道质量进行测量，并将测量结果携带在CSI中上报给网络设备。
终端设备基于该SSB进行测量可以指终端设备可以对该SSB的RSRP、参考信号测量质量(reference signal received quality，RSRQ)、接收信号强度指示(received signal strength indication，RSSI)、信号与干扰加噪声比(signal to interference plus noise ratio，SINR)等进行测量。
下面以终端设备根据CSI上报配置所指示的上报内容，确定与CSI相关联的CORESET组索引为例进行描述。
例如，终端设备可以根据上报内容中是否包括SSB索引和/或SSB对应的RSRP。如果上报内容中包括SSB索引和/或SSB对应的测量参数，则终端设备可以确定与该CSI关联的CORESET组索引为第一索引。
举例说明，如果上报内容中包括SSB索引和/或SSB对应的RSRP，则终端设备可以确定与该CSI关联的CORESET组索引为0。如果上报内容(例如reportQuantity)中包括基于SSB的测量参数(例如ssb-Index-RSRP)，则终端设备需要基于SSB进行CSI的相关测量，此时终端设备可以确定与该CSI关联的CORESET组索引为0。
当然，该方式也可以与其他方式相结合。例如，如果上报内容中包括SSB的测量参数，则终端设备可以确定与该CSI关联的CORESET组索引为0。如果上报内容中不包括与SSB相关的测量量，则终端设备可以根据上文描述的其他方式(如方式1或方式2)，确定与该CSI关联的CORESET组索引。
CORESET组索引为0对应的TRP一般为服务TRP，CORESET组索引为1对应的TRP一般为协作TRP，而终端设备只会检测服务TRP发送SSB，因此，终端设备可以根据CSI上报内容是否包括SSB相关的配置，就可以判断该TRP是否为服务TRP，即该TRP对应的CSI是否关联CORESET组索引0，而不需要额外的信令。
当然，终端设备也可以根据上报内容中是否包括SSB对应的RSRQ、RSSI和/或SINR，确定与该CSI关联的CORESET组索引，本申请实施例对此不做具体限定。
上文描述的对中方式可以单独实施，也可以相互结合来实施。以上几种方式一起使用时，例如可以先根据一种方式判断，如不满足再根据另一种方式判断，如图10所示。
终端设备在根据CSI对应的CSI上报配置，确定与CSI关联的CORESET组索引时， 可以先判断CSI上报配置所指示的用于测量CSI的测量资源中是否包括SSB。如果测量资源中包括SSB，则确定与CSI关联的CORESET组索引为0；如果测量资源中没有包括SSB，则终端设备可以进一步判断上报内容中是否包括与SSB相关的测量量。如果上报内容中包括与SSB相关的测量量，则可以确定与CSI关联的CORESET组索引为0；如果上报内容中不包括与SSB相关的测量量，则可以进一步判断ID是否为偶数。如果ID为偶数，则确定与CSI关联的CORESET组索引为0，如果ID不是偶数，则确定与CSI关联的CORESET组索引为1。
本申请实施例中的第一索引和第二索引可以相同，也可以不同，本申请实施例对此不作具体限定。
终端设备根据与CSI关联的CORESET组索引，确定该CSI能否与其他上行信息进行复用后传输。可选地，用于传输该其他上行信息的至少部分时域资源单元与用于传输该CSI的至少部分时域资源单元相同。
时域资源单元可以为以下中的至少一种：时隙、子时隙和OFDM符号。例如，时域资源单元可以是一个时隙，或者一个迷你时隙，或者一个OFDM符号。其中，一个迷你时隙可以由同一个时隙内的多个OFDM符号组成。
用于传输该其他上行信息的至少部分时域资源单元与用于传输该CSI的至少部分时域资源单元相同可以指，用于传输该其他上行信息和该CSI的部分或全部的时域资源单元相同。
例如，传输第一上行信息的时域资源单元为第一时隙，传输CSI的时域资源单元也为第一时隙，则该第一上行信息属于本申请实施例中的其他上行信息。又例如，如果传输第二上行信息的时域资源单元为第一时隙中的符号{1,2}，传输CSI的时域资源单元为第一时隙中的符号{2,3}，则该第二上行信息也属于本申请实施例中的其他上行信息。
如果与CSI关联的CORESET组索引和与其他上行信息关联的CORESET组索引相同，则终端设备可以将该CSI与其他上行信息复用后传输。
终端设备在传输CSI和其他上行信息时，可以采用多种方式。
例如，终端设备可以将CSI和其他上行信息进行级联，然后可以在同一个PUCCH或同一个PUSCH中传输级联后的CSI和其他上行信息。其中，CSI和其他上行信息可以独立进行编码。
又例如，终端设备可以将CSI和其他上行信息进行联合编码，并在同一个PUCCH或同一个PUSCH中传输编码后的CSI和其他上行信息。
举例说明，如果其他上行信息为HARQ-ACK反馈信息，则终端设备可以将该HARQ-ACK信息与CSI复用后在用于传输CSI的PUCCH资源上传输。如果其他上行信息为PUSCH携带的上行数据，则终端设备可以将该CSI和上行数据复用后，在PUSCH中传输。
这种方式的好处是，在CSI与其他上行信息对应同一个TRP时，通过信号的复用可以避免信号被丢弃。
如果与CSI关联的CORESET组索引和与其他上行信息关联的CORESET组索引不同，则终端设备确定该CSI和其他上行信息不能复用后传输，例如，终端设备可以不发送该CSI和其他上行信息。换句话说，终端设备不期望CSI和其他上行信息在相同的时域资源单元 上传输。
网络设备在进行资源调度时，关联不同的CORESET组索引的CSI与上行信息应该被配置在不同的时域资源上。如果出现关联不同的CORESET组索引的CSI与上行信息被配置在相同时域资源单元上的情况，终端设备可以当做一个错误情况(error case)，既不传输CSI，也不传输其他上行信息。
在本申请实施例中，其他上行信息为以下信息中的至少一种：HARQ-ACK、SR、CSI和PUSCH承载的上行数据。其中，HARQ-ACK、SR可以通过PUCCH承载，CSI可以通过PUCCH或PUSCH承载。
与其他上行信息关联的CORESET组索引可以通过约定的方式来得到。例如，如果其他上行信息为PUSCH承载的数据，则与其关联的CORESET组索引可以为调度该PUSCH的DCI所在的CORESET的CORESET组索引；如果其他上行信息为非周期性CSI，则与其关联的CORESET组索引可以为调度该非周期性CSI的DCI所在的CORESET的CORESET组索引；如果其他上行信息为HARQ-ACK信息，则与其关联的CORESET组索引可以为调度该HARQ-ACK对应的PDSCH的DCI所在的CORESET的CORESET组索引；如果其他上行信息为周期性CSI或半持续性CSI，则终端设备可以采用上文描述的方法确定与其关联的CORESET组索引。
本申请实施例提供的技术方案，当用于发送CSI的时域资源与发送其他上行信息的时域资源发生冲突时(即至少部分时域资源单元相同时)，如果终端设备不能得知与CSI关联的CORESET组索引，终端设备将无法确定CSI与冲突的上行信息是否对应相同的TRP，也就无法确定能否将他们进行复用传输。通过本申请实施例的方法确定出与CSI关联的CORESET组索引后，终端设备就可以确定CSI与冲突的上行信息是否对应相同的TRP，从而能够确定能否将他们进行复用传输。
本申请实施例提供的方法可以应用在任何场景中，或者终端设备可以根据是否需要在CSI对应的服务小区(serving cell)同时检测多个DCI，确定是否需要采用本申请实施例的方法来确与CSI关联的CORESET组索引。
作为一个示例，当出现以下中的至少一种情况时：
1)该服务小区的激活带宽部分(bandwidth part，BWP)上配置的多个CORESET被配置了不同的CORESET组索引值。
2)该服务小区的至少一个BWP上配置的多个CORESET被配置了不同的CORESET组索引值。
3)该服务小区的激活BWP上配置了多于3个的CORESET。
4)该服务小区的至少一个BWP上配置了多个3个的CORESET。
终端设备认为需要在CSI对应的服务小区同时检测多个DCI，此时，终端设备需要根据上文描述的方法，确定与CSI关联的CORESET组索引。当以上条件不满足时，即终端设备不需要在CSI对应的服务小区上同时检测多个DCI时，终端设备可以直接确定与CSI关联的CORESET组索引为0，或者直接确定该CSI可以与其他上行信息进行复用后传输，而不需要根据上文描述的方法进行判断。
上文中详细描述了根据本申请实施例的无线通信的方法，下面将结合图11至图14，描述根据本申请实施例的装置，方法实施例所描述的技术特征适用于以下装置实施例。
图11是本申请实施例提供的一种终端设备的示意性框图，该终端设备可以是上文描述的任一种终端设备。图11所示的终端设备1100包括处理单元1110，其中：
