请参见图1，图1是本申请实施例提供的一种物理下行共享信道PDSCH配置方法的流程示意图。需要说明的是，本申请实施例的物理下行共享信道PDSCH配置方法由终端设备执行。如图1所示，该方法可以包括如下步骤：
步骤101，接收第一配置信息，该第一配置信息用于指示具有链接关系的至少两个搜索空间集SS set，以及每个搜索空间集对应的控制资源集CORESET的信息。
其中，该至少两个搜索空间集对应的CORESET的CORESETPoolIndex不同。
具有链接关系是指，至少两个搜索空间集SS set中对应的PDCCH候选时频资源(PDCCH candidate)索引值相同的至少两个PDCCH候选时频资源用于发送相同的下行控制信息DCI。发送相同的DCI可以理解为PDCCH重复发送。
可选地，该第一配置信息是网络设备通过无线资源控制RRC信令发送的。
步骤102，响应于第一配置信息确定物理下行共享信道PDSCH的配置信息，其中，该PDSCH对应的下行控制信息DCI通过具有链接关系的至少两个搜索空间集中的至少两个物理下行控制信道PDCCH候选时频资源传输。
可选地，PDSCH的配置信息包括dataScramblingIdentityPDSCH、rateMatchPattern和HARQ-ACK反馈配置信息中的至少一项。
该PDSCH对应的DCI，是通过步骤101中指示的具有链接关系的至少两个搜索空间集中的具有相同索引值的至少两个PDCCH候选时频资源传输的。
可选地，该PDSCH的配置信息是通过接收RRC信令确定的。
在一些实施方式中，该方法还包括：接收第一媒体接入层(Medium Access Control，MAC)控制元素(Control Element，CE，或称控制单元)，该第一媒体接入控制层控制元素用于指示该DCI中的传输配置指示TCI域对应的至少一个码点对应的至少一个TCI状态，确定该PDSCH配置信息为指定控制资源集池索引CORESETPoolIndex对应的PDSCH配置信息。
其中，TCI域(field)对应的至少一个码点(codepoint)是指，比如TCI域有3比特，则TCI域对应8个码点，每个码点会对应至少一个TCI状态。每个TCI状态会对应至少一个准共址(Quasi Co-location，QCL)类型(Type)，其中QCL Type包括Type A，Type B，Type C和Type D中的至少一项。
可选地，指定控制资源集池索引CORESETPoolIndex为0,1,2中的其中一项。
在一些实施方式中，TCI域对应的码点中，若每个码点都只对应最多一个TCI状态，则该指定控制资源集池索引CORESETPoolIndex为0或1。
在一些实施方式中，TCI域对应的码点中，若至少有一个码点对应多个TCI状态，则该指定控制资源集池索引CORESETPoolIndex为0,1或2。
其中，控制资源集池索引CORESETPoolIndex为2对应的PDSCH的配置信息，是单独配置的，区别于控制资源集池索引CORESETPoolIndex为0或1对应的PDSCH配置信息。
进一步地，其中指定控制资源集池索引为2对应具有链接关系的至少两个搜索空间集的控制资源集池索引。
也就是，为具有链接关系的至少两个搜索空间集单独配置控制资源集池索引。如果具有链接关系的至少两个搜索空间集关联的控制资源集里面没有独立搜索空间集，则这个控制资源集的控制资源集池索引也为2。否则，这个控制资源集的控制资源集池索引还是为0或1。即控制资源集池索引为2只针对 控制资源集中与其它搜索空间集有链接关系的搜索空间集。其中，独立搜索空间集指与任意其它搜索空间集没有链接关系的搜索空间集。
在本实施例的一种实现方式中，该指定控制资源集池索引，是根据无线资源控制RRC信令或者默认规则确定的。
也就是，根据RRC信令或者默认规则，确定指定控制资源集池索引，进一步地，确定PDSCH的配置信息为指定控制资源集池索引对应的PDSCH的配置信息。
在本实施例的一种实现方式中，该指定控制资源集池索引为至少两个搜索空间集中编号较小的搜索空间集对应的CORESET对应的控制资源集池索引。
也就是，该具有链接关系的至少两个SS set中，编号较小的SS set对应的CORESET对应的CORESETPoolIndex作为该指定控制资源集池索引。
在本实施例的一种实现方式中，该指定控制资源集池索引为至少两个搜索空间集对应的至少两个CORESET中CORESET编号较小的CORESET对应的控制资源集池索引。
也就是，该具有链接关系的至少两个SS set对应的至少两个CORESET中，CORESET编号较小的CORESET对应的CORESETPoolIndex作为指定控制资源集池索引。
在本实施例的一种实现方式中，该PDSCH的配置信息为该码点对应的PDSCH的配置信息。
进一步地，接收第二配置信息，该第二配置信息用于确定TCI域的每个码点对应的控制资源集池索引，码点对应的PDSCH的配置信息包括码点对应的控制资源集池索引对应的PDSCH的配置信息。
也就是，通过码点和PDSCH的配置信息的关联关系，根据码点确定对应的PDSCH的配置信息。进一步地，通过接收第二配置信息，确定码点对应的CORESETPoolIndex，码点对应的PDSCH的配置信息为码点对应的CORESETPoolIndex对应的PDSCH的配置信息。也就是通过码点确定指定控制资源集池索引。
需要说明的是，TCI域对应的所***点可以对应相同的CORESETPoolIndex，也可以对应不同的CORESETPoolIndex。比如，TCI域的8个码点全部对应CORESETPoolIndex 0，也可以码点000,001,010对应CORESETPoolIndex 0，码点011,100,101对应CORESETPoolIndex 1，码点110,111对应CORESETPoolIndex 2。每个码点也可以对应多个控制资源集池索引，比如码点111对应的CORESETPoolIndex为0,1或者1,2等等。
可选地，RRC信令中包含至少一个控制资源集池索引对应的PDSCH的配置信息。
在本申请实施例中，HARQ-ACK反馈配置信息包括独立反馈配置或者联合反馈配置。
其中，独立反馈配置用于指示对应不同控制资源集池索引的PDSCH对应不同的HARQ-ACK码本；
联合反馈配置用于指示对应不同控制资源集池索引的PDSCH对应一个HARQ-ACK码本的不同比特位置。
可以理解的是，该联合反馈配置可以是部分的对应不同控制资源集池索引的PDSCH对应的HARQ-ACK的联合。比如，有控制资源集池索引为0,1和2对应的三个PDSCH，可以是控制资源集池索引为0和1对应的PDSCH的HARQ-ACK反馈采用联合反馈，控制资源集池索引为2对应的PDSCH的HARQ-ACK反馈采用单独反馈，也就是，控制资源集池索引为0和1对应的PDCSH的HARQ-ACK反馈采用同一个码本中的不同比特位置，控制资源集池索引为2对应的PDSCH的HARQ-ACK反馈采用另外一个码本。
综上，通过接收第一配置信息，该第一配置信息用于指示具有链接关系的至少两个搜索空间集SS set，以及每个搜索空间集对应的控制资源集CORESET的信息，响应于第一配置信息确定物理下行共享信道PDSCH的配置信息，其中，该PDSCH对应的下行控制信息DCI通过具有链接关系的至少两个搜索空间集中的至少两个物理下行控制信道PDCCH候选时频资源传输，明确了在多个具有链接关系的SS set对应的多个CORESET对应的CORESETPoolIndex不同的情况下，PDSCH的传输配置方法，提高PDCCH重复发送时的CORESET的配置灵活性，以及PDSCH的传输灵活性。

其中，该第一MAC CE用于指示DCI中的传输配置指示TCI域对应的至少一个码点对应的至少一个TCI状态。
该DCI是通过具有链接关系的至少两个搜索空间集中的至少两个物理下行控制信道PDCCH候选时频资源传输的，也就是，该DCI是至少两个搜索空间集SS set中对应的PDCCH候选时频资源索引值相同的PDCCH候选时频资源上发送的相同的DCI。发送相同的DCI可以理解为重复发送DCI。
步骤203，确定物理下行共享信道PDSCH的配置信息。
该PDSCH是，通过具有链接关系的至少两个SS set中的至少两个PDCCH候选时频资源传输的DCI对应调度的PDSCH。
可选地，PDSCH的配置信息包括dataScramblingIdentityPDSCH、rateMatchPattern和HARQ-ACK反馈配置信息中的至少一项。

其中，控制资源集池索引CORESETPoolIndex为2对应的PDSCH的配置信息，是单独配置的，区别于控制资源集池索引CORESETPoolIndex为0或1对应的PDSCH配置信息。
进一步地，其中指定控制资源集池索引为2对应具有链接关系的至少两个搜索空间集的控制资源集池索引。
也就是，为具有链接关系的至少两个搜索空间集单独配置控制资源集池索引。如果具有链接关系的至少两个搜索空间集关联的控制资源集里面没有独立搜索空间集，则这个控制资源集的控制资源集池索引也为2。否则，这个控制资源集的控制资源集池索引还是为0或1。即控制资源集池索引为2只针对控制资源集中与其它搜索空间集有链接关系的搜索空间集。其中，独立搜索空间集指与任意其它搜索空间集没有链接关系的搜索空间集。

请参见图4，图4是本申请实施例提供的一种物理下行共享信道PDSCH配置方法的流程示意图。需要说明的是，本申请实施例的物理下行共享信道PDSCH配置方法由网络设备执行。如图4所示，该方法可以包括如下步骤：
步骤401，发送第一配置信息，以使终端设备确定物理下行共享信道PDSCH的配置信息，其中， 所述第一配置信息用于指示具有链接关系的至少两个搜索空间集，以及每个搜索空间集SS set对应的控制资源集CORESET的信息，并且其中，该PDSCH对应的下行控制信息DCI通过具有链接关系的至少两个搜索空间集中的至少两个物理下行控制信道PDCCH候选时频资源传输。
其中，该至少两个搜索空间集对应的CORESET的控制资源集池索引不同。
具有链接关系是指，至少两个搜索空间集SS set中对应的PDCCH候选时频资源(PDCCH candidate)索引值相同的至少两个PDCCH候选时频资源用于发送相同的下行控制信息DCI。发送相同的DCI可以理解为PDCCH重复发送。
在一些实施方式中，该第一配置信息是网络设备通过无线资源控制RRC信令发送的。

可选地，该方法还包括：发送RRC信令，以使终端设备通过该RRC信令确定该PDSCH的配置信息。
在一些实施方式中，该方法还包括：发送第一媒体接入层(Medium Access Control，MAC)控制元素(Control Element，CE，或称控制单元)，该第一媒体接入控制层控制元素用于指示该DCI中的传输配置指示TCI域对应的至少一个码点对应的至少一个TCI状态，确定该PDSCH配置信息为指定控制资源集池索引CORESETPoolIndex对应的PDSCH配置信息。
其中，TCI域(field)对应的至少一个码点(codepoint)是指，比如TCI域有3比特，则TCI域对应8个码点，每个码点会对应至少一个TCI状态。每个TCI状态会对应至少一个准共址(Quasi Co-location，QCL)类型(Type)，其中QCL Type包括Type A，Type B，Type C和Type D中的至少一项。
可选地，指定控制资源集池索引CORESETPoolIndex为0,1,2中的其中一项。
在一些实施方式中，TCI域对应的码点中，若每个码点都只对应最多一个TCI状态，则该指定控制资源集池索引CORESETPoolIndex为0或1。
在一些实施方式中，TCI域对应的码点中，若至少有一个码点对应多个TCI状态，则该指定控制资源集池索引CORESETPoolIndex为0,1或2。
其中，控制资源集池索引CORESETPoolIndex为2对应的PDSCH的配置信息，是单独配置的，区别于控制资源集池索引CORESETPoolIndex为0或1对应的PDSCH配置信息。
进一步地，其中指定控制资源集池索引为2对应具有链接关系的至少两个搜索空间集的控制资源集池索引。
也就是，为具有链接关系的至少两个搜索空间集单独配置控制资源集池索引。如果具有链接关系的至少两个搜索空间集关联的控制资源集里面没有独立搜索空间集，则这个控制资源集的控制资源集池索引也为2。否则，这个控制资源集的控制资源集池索引还是为0或1。即控制资源集池索引为2只针对控制资源集中与其它搜索空间集有链接关系的搜索空间集。其中，独立搜索空间集指与任意其它搜索空间集没有链接关系的搜索空间集。
在本实施例的一种实现方式中，该指定控制资源集池索引，是根据无线资源控制RRC信令或者默认规则确定的。
也就是，根据RRC信令或者默认规则，确定指定控制资源集池索引，进一步地，确定PDSCH的配置信息为指定控制资源集池索引对应的PDSCH的配置信息。

需要说明的是，TCI域对应的所***点可以对应相同的CORESETPoolIndex，也可以对应不同的CORESETPoolIndex。比如，TCI域的8个码点全部对应CORESETPoolIndex 0，也可以码点000,001,010对应CORESETPoolIndex 0，码点011,100,101对应CORESETPoolIndex 1，码点110,111对应CORESETPoolIndex 2。每个码点也可以对应多个控制资源集池索引，比如码点111对应的CORESETPoolIndex为0,1或者1,2等等。

联合反馈配置用于指示对应不同控制资源集池索引的PDSCH对应一个HARQ-ACK码本的不同比特位置。
可以理解的是，该联合反馈配置可以是部分的对应不同控制资源集池索引的PDSCH对应的HARQ-ACK的联合。比如，有控制资源集池索引为0,1和2对应的三个PDSCH，可以是控制资源集池索引为0和1对应的PDSCH的HARQ-ACK反馈采用联合反馈，控制资源集池索引为2对应的PDSCH的HARQ-ACK反馈采用单独反馈，也就是，控制资源集池索引为0和1对应的PDCSH的HARQ-ACK反馈采用同一个码本中的不同比特位置，控制资源集池索引为2对应的PDSCH的HARQ-ACK反馈采用另外一个码本。
综上，通过发送第一配置信息，以使终端设备确定物理下行共享信道PDSCH的配置信息，其中，所述第一配置信息用于指示具有链接关系的至少两个搜索空间集，以及每个搜索空间集SS set对应的控制资源集CORESET的信息，并且其中，该PDSCH对应的下行控制信息DCI通过具有链接关系的至少两个搜索空间集中的至少两个物理下行控制信道PDCCH候选时频资源传输，明确了在多个具有链接关 系的SS set对应的多个CORESET对应的CORESETPoolIndex不同的情况下，PDSCH的传输配置方法，提高PDCCH重复发送时的CORESET的配置灵活性，以及PDSCH的传输灵活性。

步骤503，发送RRC信令，以使终端设备确定物理下行共享信道PDSCH的配置信息。
