为便于理解本申请实施例的技术方案，以下对本申请实施例的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
在NR系统中，网络设备发送上行授权(Uplink grant，UL grant)信息，例如格式0_0(format 0_0)或格式0_1(format 0_1)的下行控制信息(Downlink Control Information，DCI)，以调度物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输。
网络设备通过UL grant信息调度上行数据传输时，会在DCI中携带时域资源分配(Time Domain Resource Allocation，TDRA)域。TDRA域为6比特(bit)数据，用于指示资源分配表格中16行中的一行。
资源分配表格中每一行包含多种不同的资源分配信息，例如PUSCH起始位置S，PUSCH长度L，时间间隔信息K 2以及映射类型(Type)等。其中，K 2表示UL grant信息所在的时隙和PUSCH所在的时隙之间偏移的时隙数量。PUSCH时域资源分配的映射类型包括A类(Type A)和B类(Type B)。Type A和Type B的区别包括：S的取值范围不同以及L的取值范围不同。Type A主要面向时隙型调度(slot-based)业务，S比较靠前，L比较长。Type B主要面向高可靠低时延通信(Ultra Reliability and Low Latency  Communication，URLLC)等非时隙型调度业务，对时延要求较高，因此S的位置比较灵活以便传输随时到达的业务数据，L较短，可降低传输时延。
Type A和Type B的S和L的取值范围如下表1所示。

PUSCH的时域资源分配表格如下表2所示。

其中，j为UL grant信息所在的时隙。
为了增强上行传输的可靠性，NR R15标准中引入了时隙聚合PUSCH重复传输。时隙聚合PUSCH重复传输是指同一个传输块采用不同的冗余版本重复传输K次。网络设备通过高层参数PUSCH聚合因子(pusch-AggregationFactor)为终端设备配置最大重复次数K，终端设备在K个连续的时隙上重复发送相同的传输块，且每个时隙中承载该传输块的PUSCH副本在时域上占用相同数量的符号。其中，第一个PUSCH副本的冗余版本(Redundancy Version，RV)是由上行授权信息如DCI指示的，其余PUSCH副本的RV是基于集合{0,2,3,1}顺序循环确定。冗余版本的编号RV id如下表3所示：
Figure PCTCN2021086712-appb-000002
表3
如果PUSCH副本所在的时隙中，与PUSCH副本对应的时域资源包含至少一个半静态下行符号，则在该时隙中不发送PUSCH。如图2所示的PUSCH重复传输的一个时域资源示意图，网络设备调度终端设备将传输块重复发送4次，传输块的PUSCH副本需要占用每个时隙中前12个符号。其中，U为上行符号，D为半静态下行符号，F为灵活符号。由于时隙#1和时隙#2中的前3个符号是半静态下行符号D，因此在时隙#1上待发送的第2个PUSCH(PUSCH#2)和时隙#2上待发送的第3个PUSCH(PUSCH#3)被丢弃而不被发送。
对于上行免调度的时隙聚合PUSCH重复传输，网络设备利用高层参数RepK配置传输块的最大重复次数。
在NR R16标准中，对于基于Tpye B的PUSCH重复传输，网络设备发送上行授权信息或者免授权配置信息，指示一个或多个名义PUSCH的重复传输。
终端设备在一个时隙中传输一个或多个实际PUSCH副本，或者在连续多个可用的时隙中传输两个或多个实际PUSCH副本。前述已经说明，网络设备通过指示TDRA表中的某一行，实现时域资源的指定。根据NR R16标准，TDRA表中还增加一列，用于指示Type B的PUSCH重复传输的副本个数numberofrepetition，其取值可以为{1，2，3，4，7，8，12，16}。
上行调度信息或者第一类免授权配置信息指示第一个名义PUSCH的起始符号S和持续时间L，每一个名义PUSCH副本的持续时间L相同，其中，0≤S≤13，1≤L≤14，高层信令各用4bit分别指示S和L，可以实现S+L>14。名义PUSCH和实际PUSCH副本的传输块大小(Transport Block Size，TBS)可根据名义PUSCH的时域长度L确定。从第二个名义PUSCH开始，名义PUSCH副本的起始符号是上一个名义PUSCH副本的终止符号的下一个符号。
终端设备在确定实际PUSCH副本的时域资源之前，需要确定无效符号，除无效符号外的符号可以认为是潜在有效符号。如果一个名义PUSCH副本对应的时域资源包括在同一隙内连续的至少一个潜在有效符号，则可以将该至少一个潜在有效符号映射为一个实际PUSCH副本。因此，一个名义PUSCH副本的时域资源可包含一个或多个实际PUSCH副本的时域资源。此外，终端设备不发送单个符号的实际PUSCH副本，除非单个符号是网络设备指示的名义PUSCH的持续时间L。
图3示出了示例性的PUSCH重复传输的时域资源示意图。如图3所示，名义PUSCH的长度L为6个符号，名义重复次数为4，则在24个符号中包含4个名义PUSCH重复。其中，在每个名义PUSCH副本对应的6个符号中，下行符号或其他无效的符号不用于实际PUSCH传输。以第3个名义PUSCH重复为例，其对应的6个符号均为潜在有效符号，则6个符号中，在同一时隙内连续的第1个符号和第2个符号映射为一个实际PUSCH，在同一时隙内连续的第3个符号至第6个符号映射为另一个实际PUSCH。以第4个名义PUSCH重复为例，其对应的6个符号中，第1个符号、第5个符号和第6个符号为潜在有效符号。其中，第1个符号不与其他潜在有效符号连续，因此第1个符号不用于实际PUSCH传输，第5个符号和第6个符号在同一时隙内连续，可映射为一个实际PUSCH。
在上述方案中，终端设备可基于以下方式确定无效符号：
1、由高层参数tdd-UL-DL-ConfigurationCommon或tdd-UL-DL-Configuration Dedicated半静态配置的下行符号是一种无效符号。
2、根据高层信令配置的无效符号图样InvalidSymbolPattern确定无效符号。其中，无效符号图样包括对应多个符号的多个比特，以取值为1的比特表示对应的符号为无效符号。格式0_1或者0_2的DCI用于调度PUSCH重复，或者激活第二类免授权 PUSCH重复。该DCI中可配置1Bit的无效符号图样指示信息域，当无效符号图样指示信息域为1时，终端设备根据无效符号图样确定无效符号，否则，终端设备忽略无效符号图样。如果DCI中不包含无效符号图样指示信息域，则终端直接根据无效符号图样确定无效符号。不同的DCI格式独立配置无效符号图样指示信息域。
对于基于Tpye A的PUSCH重复传输，NR系统支持在高层信令配置的时域资源分配表中增加一列numberofrepetitions用于指示Type A的PUSCH重复传输次数K。如果没有配置numberofrepetitions，则基于高层参数聚合因子pusch-AggregationFactor确定重复次数K。如果前述两个参数都没有配置，则重复次数K＝1。
对于免授权PUSCH调度：
免授权PUSCH重复类型的确定方式包括：当高层参数PUSCHRepTypeIndicatorForType1Configuredgrant配置为pusch-RepTypeB时，采用B类PUSCH重复，否则采用A类PUSCH重复。免授权重复次数的确定方式包括：如果时域资源分配表中包含numberofrepetitions，则PUSCH的名义重复传输次数由TDRA表指示，否则重复次数由高层参数repK指示。
可见，PUSCH的重复传输次数是半静态配置的，由于系统支持灵活时隙结构，因此，在部分时隙(slot)中，PUSCH的重复会被忽略，导致实际重复传输PUSCH的时域资源不连续。因此，在一些配置场景尤其是时分双工(Time Division Duplex，TDD)场景下，配置的重复次数不能达到理想的覆盖增强效果。
由于进行联合信道估计，需要确定进行联合信道估计的时隙数或PUSCH的重复传输次数，以确定对应的时域范围。在对应的时域范围内，网络设备假设DMRS是相关的，例如DMRS的功率、天线端口和预编码中的至少之一持续不变和/或相位连续，基于此进行联合信道估计。相应的，终端设备应在PUSCH的传输中实现这些与联合信道估计相关的假设。如图4所示的连续时隙的联合信道估计示意图，终端设备需要在重复传输PUSCH的时隙#0至时隙#3中基于前导DMRS和附加DMRS进行联合信道估计，并保持与联合信道估计相关的配置。然而，由于实际重复传输PUSCH的时域资源存在不连续的情况，因此，终端设备难以在整个PUSCH的重复传输期间配合网络设备进行相应配置，即保持DMRS的功率、天线端口、预编码不变和/或保持相位连续等。
本申请实施例提供的方案，主要用于解决上述问题中的至少一个。
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
图5是根据本申请一实施例的信道估计方法的示意性流程图。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括：
步骤S510，终端设备基于接收到的来自网络设备的第一指示信息，确定用于重复传输第一数据的第一时域资源集合；
步骤S520，终端设备基于第一时域资源集合，确定用于进行联合信道估计的第二时域资源集合。
本申请实施例中，第二时域资源集合可以包括用于进行联合信道估计的至少一个时域资源。也就是说，网络设备在第二时域资源集合所包含的时域资源上进行联合信道估计。相应的，终端设备在第二时域资源集合中保持与联合信道估计关联的配置。
可选地，上述信道估计方法还可以包括：
终端设备在第二时域资源集合中，基于与联合信道估计对应的信号配置传输第一数据。
可选地，与联合信道估计对应的信号配置包括以下至少之一：
持续不变的功率；
持续不变的天线端口；
持续不变的预编码；
连续的相位。
与上述方法对应的，参见图6，本申请另一实施例提供一种信道估计方法。该方法可选地可以应用于图1所示的系统，但并不仅限于此。该方法包括：
步骤S610：网络设备向终端设备发送第一指示信息；其中，第一指示信息用于指示终端设备确定用于重复传输第一数据的第一时域资源集合；第一时域资源集合用于确定用于进行联合信道估计的第二时域资源集合。
可选地，上述方法还包括：所述网络设备在所述第二时域资源集合中，进行针对所述第一数据的联合信道估计。或者说网络设备在第二时域资源集合所包含的至少一个时域资源上，进行针对第一数据的联合信道估计。
示例性地，第一数据可以包括PUSCH。
本申请实施例中，用于重复传输第一数据的第一时域资源集合可以包括实际传输第一数据的时隙或符号。例如，对于Type A的上行数据传输，第一时域资源集合可以包括至少一个时隙，该时隙中与PUSCH副本对应的至少一个符号中不包含半静态下行符号；对于Type B的上行数据传输，第一时域资源集合可以包括实际PUSCH对应的符号。
需要说明的是，第一时域资源集合可以包括连续的时域资源，也可以包括离散的时域资源。第二时域资源集合可以包括连续的时域资源，也可以包括离散的时域资源。这里，时域资源可以包括时隙和/或符号。
可选地，第一指示信息可以包括以下至少之一：
上行授权信息；
免授权指示信息；
第二窗口长度指示信息。
可选地，上行授权信息可以包括DCI例如DCI format 0_0或DCI format 0_1。终端设备可以根据上行授权信息，确定重复传输的时域范围，并基于重复传输的时域范围中各时隙的时隙结构或者说符号配置，确定用于重复传输第一数据的第一时域资源集合。
可选地，免授权指示信息可以包括用于配置免调度资源的配置信息。或者，免授权信息可以包括在已配置免调度资源的情况下发送的用于激活某些免调度资源的激活信息。终端设备可以根据免授权指示信息确定生效的免调度资源，在需要利用其中部分或全部免调度资源进行重复传输的情况下，确定免调度资源中可用于重复传输第一数据的第一时域资源集合。网络设备在配置或激活免调度资源的情况下，也可以确定免调度资源中可用于重复传输第一数据的第一时域资源集合。
可选地，第一指示信息可以携带上行授权信息或免授权信息以指示第一时域资源集合，同时携带第二窗口长度指示信息以便于终端设备根据第二窗口长度指示信息确定第二时域资源集合。第二窗口长度指示信息可以用于指示确定第二时域资源集合所需的与时域窗口或者说时域区间、时域范围的长度相关的信息，例如，名义窗口长度、窗口长度阈值、间隔阈值等。示例性地，名义窗口长度可以用于在第一时域资源集合所对应的时域范围中确定出名义窗口，以在名义窗口中确定第二时域资源集合。示例性地，窗口长度阈值可以包括第二时域资源集合所对应的连续的时域范围的长度或第二时域资源集合所包含的时域资源的数量阈值。示例性地，间隔阈值可以包括第二时域资源集合中允许中断的时域区间的长度阈值或者说允许中断的时域资源的数量阈值。
本申请实施例中，网络设备在第二时域资源集合中进行针对第一数据的联合信道估计之前，也可以基于上述第一时域资源集合确定第二时域资源集合。具体的，信道 估计方法还可以包括：网络设备基于第一时域资源集合，确定第二时域资源集合。
本申请实施例中，网络设备或终端设备可采用多种方式实现基于第一时域资源集合确定第二时域资源集合。以下提供多种示例性的实施方式：
示例一：网络设备基于第一时域资源集合，确定第二时域资源集合，包括：
网络设备将第一时域资源集合确定为第二时域资源集合；其中，第一时域资源集合包括至少两个时域资源。
相应的，终端设备基于所述第一时域资源集合，确定用于进行联合信道估计的第二时域资源集合，包括：所述终端设备将所述第一时域资源集合确定为所述第二时域资源集合；其中，所述第一时域资源集合包括至少两个时域资源。
可选地，时域资源包括时隙或符号。
例如，如图7所示，对于TypeA的上行数据传输，重复传输PUSCH的时域范围(以下称重传时域范围)包括5个时隙，分别为时隙#0至时隙#4。其中，时隙#1中与PUSCH#2对应的时域资源包含3个下行符号D，时隙#2中与PUSCH#3对应的时域资源包含3个下行符号D，因此，时隙#1和时隙#2中不进行PUSCH重复传输，则用于重复传输PUSCH的第一时域资源集合包括时隙#0、时隙#3和时隙#4。因此，将时隙#0、时隙#3和时隙#4整体确定为第二时域资源集合，即第二时域资源集合包括时隙#0、时隙#3和时隙#4。网络设备基于时隙#0、时隙#3和时隙#4进行联合信道估计。终端设备在时隙#0、时隙#3和时隙#4上保持功率、天线端口、预编码不变和/或相位连续。
又如，如图8所示，对于TypeB的上行数据传输，重传时域范围包括24个符号，对应4个名义PUSCH。其中，用于重复传输PUSCH的第一时域资源集合包括6个实际PUSCH占用的符号。终端设备将这些符号整体确定为用于进行联合信道估计的第二时域资源集合。也就是说，第二时域资源集合包括6个实际PUSCH占用的符号。网络设备基于6个实际PUSCH占用的符号进行联合信道估计。终端设备在6个实际PUSCH占用的符号上保持功率、天线端口、预编码不变和/或相位连续。
示例二：网络设备基于第一时域资源集合，确定第二时域资源集合，包括：
网络设备基于第一时域资源集合中具有预设关系的M个时域资源，得到第二时域资源集合；其中，M为大于等于1的整数。
相应的，所述终端设备基于所述第一时域资源集合，确定用于进行联合信道估计的第二时域资源集合，包括：
所述终端设备基于所述第一时域资源集合中具有预设关系的M个时域资源，得到所述第二时域资源集合；其中，M为大于等于1的整数。
示例性地，网络设备或终端设备可以将第一时域资源集合中具有预设关系的M个时域资源，确定为第二时域资源集合。
可选地，预设关系包括在时域上连续。相应的，M可以大于等于2。也就是说，终端设备基于第一时域资源集合中在时域上连续的至少两个时域资源，得到联合信道估计的资源集合。
可选地，上述时域资源可以包括时隙或符号。
例如，如图9所示，用于重复传输PUSCH的第一时域资源集合包括时隙#0、时隙#3和时隙#4，其中，时隙#0没有相连续的其他可用于PUSCH数据传输的时隙，因此时隙#0确定为一个联合信道估计的第二时域资源集合，记为第1个第二时域资源集合；时隙#3和时隙#4在时域上连续，因此，可以将时隙#3和时隙#4整体确定为一个第二时域资源集合，记为第2个第二时域资源集合。
又如，如图10所示，用于重复传输PUSCH的第一时域资源集合包括6个实际 PUSCH占用的符号。其中，第1个实际PUSCH占用的两个符号在时域上连续，因此，可以将第1个实际PUSCH占用的两个符号确定为一个第二时域资源集合，记为第1个第二时域资源集合。类似地，可以将第2个实际PUSCH占用的两个符号确定为第2个第二时域资源集合，将第3个实际PUSCH、第4个实际PUSCH和第5个实际PUSCH占用的10个符号确定为第3个第二时域资源集合，将第6个实际PUSCH占用的2个符号确定为第4个第二时域资源集合。
可选地，如果第一时域资源集合中的某个时域资源例如第三时域资源与时域资源集合中的其他时域资源在时域上均不连续，则终端设备或网络设备可以将第三时域资源确定为一个第二时域资源集合。在一些场景下，也可以认为第三时域资源用于进行单信道估计或独立信道估计。
例如，如图9所示，时隙#0可用于重复传输第一数据，且与第一时域资源集合中其他资源不连续，因此，可以将时隙#0确定为第1个第二时域资源集合。
可选地，M小于等于预先配置的资源数量阈值。在M个时域资源在时域上连续的情况下，资源数量阈值也可以视为窗口长度阈值。
例如，M＝6。如图11所示，用于重复传输第一数据的时域资源集合包括6个实际PUSCH占用的符号。其中，第3个实际PUSCH、第4个PUSCH和第5个实际PUSCH占用的10个符号在时域上连续，但符号数量大于资源数量阈值。终端设备和网络设备将前6个在时域上连续的符号(即第3个实际PUSCH和第4个实际PUSCH占用的符号)确定为第i个第二时域资源集合，将后4个在时域上连续的符号(即第5个实际PUSCH占用的符号)确定为第i+1个第二时域资源集合。
可选地，信道估计方法还可以包括：
在第一时域资源集合中的第一时域资源与第一时域资源集合中的第二时域资源之间的时间间隔小于等于间隔阈值的情况下，终端设备和/或网络设备确定第一时域资源和第二时域资源具有预设关系。
也就是说，若时域资源集合中两个时域资源之间的时间间隔小于间隔阈值，则这两个时域资源具有预设关系。可以理解，根据上述可选方式，预设关系包括：在时域上中断的长度小于等于间隔阈值。从另一角度而言，若M个时域资源在时域上中断的长度小于等于间隔阈值，即M个时域资源中两个时域资源之间的时间间隔小于间隔阈值，则可以忽略这两个时域资源之间的间隔，将M个时域资源整体视为第二时域资源集合。
例如，间隔阈值为2个时隙。如图7所示，用于重复传输PUSCH的第一时域资源集合包括时隙#0、时隙#3和时隙#4。其中，时隙#0和时隙#3之间的时间间隔等于2个时隙，时隙#3和时隙#4之间的时间间隔为0(小于2个时隙)，因此，时隙#0、时隙#3和时隙#4具有预设关系。基于此，终端设备或网络设备将时隙#0、时隙#3和时隙#4确定为第二时域资源集合。如图12所示，用于重复传输PUSCH的第一时域资源集合包括时隙#0、时隙#4和时隙#5。其中，时隙#0和时隙#4之间的时间间隔大于2个时隙，时隙#4和时隙#5之间的时间间隔为0(小于2个时隙)，因此，时隙#0和时隙#4不具有预设关系。时隙#4和时隙#5具有预设关系。基于此，终端设备或网络设备将时隙#4和时隙#5整体确定为第2个第二时域资源集合。将时隙#0单独确定为第1个第二时域资源集合。
又如，间隔阈值为2个符号。如图13所示，用于重复传输PUSCH的第一时域资源集合包括6个实际PUSCH占用的符号。其中，第1个实际PUSCH占用的符号与第2个PUSCH占用的符号之间的时间间隔小于间隔阈值，因此，两者之间存在预设关系，第1个第二时域资源集合包括第1个实际PUSCH占用的符号与第2个实际 PUSCH占用的符号。第2个实际PUSCH占用的符号与第3个实际PUSCH占用的符号之间的时间间隔大于间隔阈值，因此，两者之间不存在预设关系，属于不同的第二时域资源集合。
示例三：网络设备基于时域资源集合，确定联合信道估计窗口，包括：
网络设备根据名义窗口长度，在第一时域资源集合所对应的时域范围中确定出N个名义窗口；其中，N为大于等于1的整数；
网络设备在N个名义窗口中的第i个名义窗口中，基于属于第一时域资源集合且具有预设关系的M个时域资源，得到第二时域资源集合；其中，i为大于等于1且小于等于N的整数，M为大于等于1的整数。
相应的，所述终端设备基于所述第一时域资源集合，确定用于进行联合信道估计的第二时域资源集合，包括：
所述终端设备根据名义窗口长度，在所述第一时域资源集合所对应的时域范围中确定出N个名义窗口；其中，N为大于等于1的整数；
所述终端设备在所述N个名义窗口中的第i个名义窗口中，基于属于所述第一时域资源集合且具有预设关系的M个时域资源，得到所述第二时域资源集合；其中，i为大于等于1且小于等于N的整数，M为大于等于1的整数。
这里，第一时域资源集合所对应的时域范围可以指起点为第一时域资源集合中第一个时域资源且终点为第一时域资源集合中最后一个时域资源的时域区间。
根据示例三，可以先基于预先设定的名义窗口长度，将第一时域资源集合所对应的时域范围划分为至少一个名义窗口，例如，窗口长度为20个符号，时域资源集合所对应的时域范围为40个符号，则可以将第一时域资源集合所对应的时域范围划分为2个名义窗口。再在每个名义窗口中，将属于第一时域资源集合且具有预设关系的M个时域资源确定为联合信道窗口。
可选地，时域资源包括时隙或符号。
可选地，M小于等于预先配置的资源数量阈值。
可选地，预设关系包括在时域上连续。
可选地，信道估计方法还可以包括：
在第一时域资源集合中的第一时域资源与第一时域资源集合中的第二时域资源之间的时间间隔小于等于间隔阈值的情况下，终端设备和/或网络设备确定第一时域资源和第二时域资源具有预设关系。
实际应用中，上述示例二可视为示例三中名义窗口数量N＝1的情况。也就是说，可以将第一时域资源集合对应的时域范围视为一个名义窗口。可以理解，在每个名义窗口中基于M个时域资源得到为第二时域资源集合的方式，可以参考上述示例二在第一时域资源集合中基于M个时域资源得到第二时域资源集合的方式实现。在此不再进行赘述。
可选地，网络设备可以向终端设备发送第二指示信息，以指示进行联合信道估计，触发终端设备确定联合信道窗口。具体地，信道估计方法还可以包括：
网络设备向终端设备发送第二指示信息；其中，第二指示信息用于指示进行联合信道估计处理。
相应的，终端设备基于所述第一时域资源集合，确定用于进行联合信道估计的第二时域资源集合，包括：
在接收到来自网络设备的第二指示信息的情况下，所述终端设备基于所述第一时域资源集合，确定所述用于进行联合信道估计的第二时域资源集合；其中，所述第二指示信息用于指示进行联合信道估计。
可选地，第二指示信息包括以下至少之一：
联合信道估计的使能信息；
第一窗口长度指示信息。
可选地，第一窗口长度指示信息可以用于指示上述示例性的实施方式中的名义窗口长度、窗口长度阈值、资源数量阈值、间隔阈值中至少之一。终端设备在接收到窗口长度指示信息的情况下，确定网络设备进行联合信道估计，因此基于第一指示信息所指示的第一时域资源集合确定用于进行联合信道估计的第二时域资源集合。
以上通过多个实施例从不同角度描述了本申请实施例的具体设置和实现方式。利用上述至少一个实施例，终端设备基于网络设备发送的第一指示信息确定用于重复传输第一数据的第一时域资源集合，基于第一时域资源集合确定用于进行联合信道估计的第二时域资源集合。从而终端设备可以基于第二时域资源集合配合网络设备准确地进行联合信道估计。
