首先，对本申请实施例中涉及的部分名词进行解释，以便于本领域技术人员理解。
1、用户设备(user equipment，UE)。本申请实施例中用户设备是一种具有无线收发功能的设备，可以称为终端(terminal)、终端设备、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、接入终端设备、车载终端设备、工业控制终端设备、UE单元、UE站、移动站、远方站、远程终端设备、移动设备、UE终端设备、无线通信设备、UE代理或UE装置等。用户设备可以是固定的或者移动的。需要说明的是，用户设备可以支持至少一种无线通信技术，例如LTE、新空口(new radio，NR)、宽带码分多址(wideband code division multiple access，WCDMA)等。例如，用户设备可以是手机(mobile phone)、平板电脑(pad)、台式机、笔记本电脑、一体机、车载终端、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧 家庭(smart home)中的无线终端、蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、可穿戴设备、未来移动通信网络中的终端设备或者未来演进的公共移动陆地网络(public land mobile network，PLMN)中的终端设备等。在本申请的一些实施例中，用户设备还可以是具有收发功能的装置，例如芯片系统。其中，芯片系统可以包括芯片，还可以包括其它分立器件。

目前，为了使得PUSCH的覆盖增强，引入了可以针对多个PUSCH的DMRS进行联合信道估计的方法，使得基站可以根据DMRS进行联合信道估计。但基站在进行联合信道估计的相关配置时，可能会使得联合信道估计时间等具体信息无法确定，造成基站或终端都无法明确具体的行为以实现联合信道 估计，以致联合信道估计无法实现，降低信道估计效率。

请参阅图2a，图2a是本申请实施例提供的一种联合信道估计方法的流程示意图，如图所示，该方法包括：
步骤201，终端接收来自网络设备发送的时间信息，所述时间信息用于指示预设时段，所述预设时段处于多个时间窗对应的时段。
其中，该时间信息包括网络设备配置的时间窗的信息，所述时间窗是指用于进行联合信道估计的一个时间段，即在通常情况下，一个时间窗对应的时间信息就为一次联合信道估计对应的时间信息。具体来说，在所述时间窗内的PUSCH传输需要保证传输的相位连续性和/或功率一致性。所述时间信息中可以包括多个时间窗的信息，则这些时间窗可以在时间上出现交叠或这些时间窗在时间上均独立。因此可以根据时间信息在这些时间窗对应的时段中确定出用于联合信道估计的具体时间。该预设时段可以是这些时间窗对应的时段中的全部时段，也可以是这些时间窗对应的时段中的部分时段。具体实现中，预设时段还可以用于指示终端或网络设备在预设时段内进行的联合信道估计的规则，即可以通过预设时段获取每个时间窗的开始时间、结束时间和联合信道估计次数等，该预设时段的相关内容可以是时间信息通过下行控制信息(Downlink Control Information，DCI)或者无线资源控制(Radio Resource Control，RRC)或者MAC层控制信息(MAC-CE)体现。当然时间信息也可以仅包括某一类时间窗的开始时间和结束时间，同时该类时间窗的其他信息可以由时间信息中对应的该时间窗的重复次数和间隔时间等内容确定。其中，当预设时段中包括多个时间窗时，这多个时间窗的时间长度可以是不同的。或者，可以是所述时间信息通过隐式的方式体现，例如通过DCI或者RRC中指示的PUSCH重传次数来确定。例如，如果DCI中指示了PUSCH要进行4次重复传输，那么所述时间信息的时间窗的长度可以包含所述4次PUSCH传输。一个具体例子是，时间窗可以起始于第一次PUSCH传输的第一个OFDM符号或者起始于第一次PUSCH传输所在时隙的第一个OFDM符号，或者起始于承载所述DCI的PDCCH的最后一个OFDM符号，或者起始于承载所述DCI的PDCCH的最后一个OFDM符号之后的一个OFDM符号。时间窗还可以终止于最后一次PUSCH传输的最后一个OFDM符号，或者终止于最后一次PUSCH传输所在时隙的最后一个OFDM符号。需要说明的是，本方案中的PUSCH可以替换为物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)。
在一个可能的实例中，在所述多个时间窗在时间上出现交叠的情况下，所述预设时段为存在交叠的多个时间窗对应的时间段的并集。
其中，网络设备会配置多个时间窗用于进行联合信道估计，但网络设备配 置的时间窗可能会在时间上出现交叠，即某一个时间窗对应的时段中可能会与其他时间窗对应的时段出现部分或全部重叠。此时，确定预设时段为存在交叠的多个时间窗对应的时间段的并集，即确定可以用于信道估计的时间为存在交叠的多个时间窗对应的时间段的并集，也就是这重叠的多个时间窗对应的全部时段内的PUSCH传输都可以用于联合信道估计。如图2b所示，图2b是本申请实施例提供的一种联合信道估计时间的示意图，图中存在时间窗1和时间窗2交叠，则此时的预设时段就是时间窗1和时间窗2对应的全部时段。
具体实现中，当确定预设时段为存在交叠的多个时间窗对应的时间段的并集后，还可以确定在该预设时段内的联合信道估计次数及每次联合信道估计的开始时间和结束时间。例如图2b中，可以确定在该预设时段内的联合信道估计次数为1次。由于在进行联合信道估计时，需要保持终端的相位连续，即该预设时段内每个PUSCH中的与相位有关的参数需要一致，因此需要确定出标准时间窗，使得该预设时段内包括的其他时间窗中的与相位有关的参数与所述标准时间窗中的与相位有关的参数一致。其中，所述标准时间窗可以是多个重叠时间窗中时间最早的那个时间窗。例如时间窗1对应的波束方向为A，时间窗2对应的波束方向为B，此时由于只在预设时段内进行一次联合信道估计，而时间窗1又为标准时间窗，因此时间窗2对应的波束方向就需要变为A。例如图2b中，还可以确定在该预设时段内的联合信道估计次数为2次。因此当预设时段中包括多个时间窗时，可以根据时间窗个数确定联合信道估计次数，具体地，该联合信道估计次数与时间窗个数相同。
具体实现中，在预设时段内包括多个时间窗时，根据每个时间窗在该预设时段中的开始时间进行排序，第一时间窗为开始时间最早的时间窗，以此类推，可以先确定第一时间窗对应的时段为一次联合信道估计时间，与所述第一时间窗交叠的第二时间窗对应的时段中，除所述与第一时间窗交叠的时段外的时段为另一次联合信道估计时间，然后再确定第三时间窗对应的时段中除与第二时间窗交叠的时段为另一次联合信道估计时间，以此类推。例如时间窗1与时间窗2交叠，时间窗2与时间窗3交叠，此时可以确定时间窗1对应的时段为一次联合信道估计的时段，时间窗2对应的时段中未与时间窗1交叠的时段为另一次联合信道估计的时段，此时时间窗3对应的时段中未与时间窗2交叠的时 段为另一次联合信道估计的时段。
若存在多个时间窗与第一时间窗交叠，则确定这多个时间窗对应的时段中未与第一时间窗对应的时段交叠的时间段最长的时间窗为目标时间窗，确定该目标时间窗对应的时段中除所述与第一时间窗交叠的时段外的时段为另一次联合信道估计时间。若还存在其他时间窗与该目标时间窗交叠，则确定与该目标时间窗交叠的时间窗对应的时段中未与第一时间窗对应的时段交叠的时间段最长的时间窗为另一个目标时间窗，以此类推，确定出预设时段内的联合信道估计次数与每次开始和结束时间。例如时间窗1分别与时间窗2和时间窗3交叠，而时间窗3中未与时间窗1交叠的时段大于时间窗2中未与时间窗1交叠的时段，此时可以确定时间窗1对应的时段为一次联合信道估计的时段，时间窗3对应的时段为另一次联合信道估计的时间。
可见，本实例中，在多个时间窗出现交叠的情况下，确定这多个时间窗对应的时段的并集为可以进行联合信道估计的时间。这样可以明确联合信道估计的时间，提高信道估计效率。
在一个可能的实例中，在所述交叠情况为所述多个时间窗在时间上出现交叠的情况下，所述预设时段为存在交叠的多个时间窗中开始时间最早的时间窗对应的时间段。
其中，当有多个时间窗交叠时，可以确定可以用于联合信道估计的时段为开始时间最早的时间窗对应的时段。例如图2c所示，图2c是本申请实施例提供的另一种联合信道估计时间的示意图，在图2c中，包括相互交叠的时间窗1和时间窗2，此时由于时间窗1的开始时间要早于时间窗2的开始时间，因此预设时段为时间窗1对应的时段。
具体实现中，所述开始时间最早的时间窗可以是存在交叠关系的多个时间窗中开始时间最早的，也可以是相互交叠的两个时间窗中开始时间最早的。即根据开始时间排序，若时间窗1与时间窗2交叠，时间窗2与时间窗3交叠，时间窗4与时间窗3交叠，所有的时间窗都相互比较，确定一个开始时间最早的时间窗，则开始时间最早的时间窗是时间窗1，因此预设时段为时间窗1对应的时段。也可以根据开始时间让相互交叠的两个时间窗单独比较，已经比较过的时间窗不再参与比较，以此类推，得到多个开始时间最早的时间窗。即时 间窗1与时间窗2比较，因为时间窗2已经参与过比较，则此时时间窗3与时间窗4比较，得到开始时间较早的时间窗1和时间窗3。
具体实现中，若有多个时间窗相互交叠，确定第一时间窗对应的时段为第一预设时段，第一时间窗为开始时间最早的时间窗，确定与第一时间窗交叠的第二时间窗无效，确定与第二时间窗交叠的第三时间窗对应的时段为第二预设时段，确定第一预设时段与第二预设时段均可用于联合信道估计，以此类推，确定可以用于联合信道估计的多个预设时段。其中，若第三时间窗包括多个，则确定第三时间窗对应的时段中未与第二时间窗交叠的时段最长的时间窗为第三目标时间窗，确定第三目标时间窗对应的时段为第二预设时段。或者，若第三时间窗包括多个，则确定第三时间窗对应的时段中开始时间最早的时间窗为第三目标时间窗，确定第三目标时间窗对应的时段为第二预设时段。确定第三目标时间窗后，确定第三时间窗中的除第三目标时间窗的其他时间窗无效。
具体实现中，还可以确定多个交叠的时间窗中时间跨度最长的时间窗对应的时段为预设时段。
可见，本实例中，确定交叠的多个时间窗中开始时间最早的时间窗对应的时段为预设时段，这样可以确定具体的联合信道估计时间，提高信道估计效率。
在一个可能的实例中，在所述交叠情况为所述多个时间窗在时间上出现交叠的情况下，所述预设时段为存在交叠的多个时间窗中的每个时间窗对应的不存在交叠的时间段。
其中，当有多个时间窗出现交叠时，可以确定每个时间窗对应的时段中未出现重叠的时段为预设时段。如图2d所示，图2d是本申请实施例提供的另一种联合信道估计时间的示意图，图中时间窗1和时间窗2出现交叠，此时可以确定时间窗1未出现交叠的前一部分时段为一个预设时段，时间窗2未出现交叠的后一部分时段也为一个预设时段，因此这两个预设时段都可以用于进行联合信道估计。
具体实现中，当预设时段中包括多个时间窗时，可以确定该预设时段内的联合信道估计次数与时间窗个数相同，即每个时间窗对应的时段都为一次联合信道估计的时段。
可见，本实例中，确定多个时间窗中的每个时间窗对应的不存在交叠的时 间段为可以用于联合信道估计的预设时段，这样可以明确联合信道估计的时间，提高信道估计效率。
在一个可能的实例中，所述时间信息还用于指示所述多个时间窗在时间上均不存在交叠。
其中，由于时间信息是根据网络设备配置的时间窗的信息，因此在网络设备进行配置时，可以禁止出现多个时间窗交叠的情况。
可见，本实例中，进行出现时间窗交叠的情况，可以明确联合信道估计时间，提高信道估计效率。
步骤202，终端根据所述预设时段发送资源。
其中，所述资源用于指示网络设备进行联合信道估计，所述资源可以是PUSCH或PUCCH。终端发送的资源中可以包括多个PUSCH或PUCCH，每个PUSCH或PUCCH中都包括可以用于信道估计的DMRS。具体实现中，每次联合信道估计时，发送的多个PUSCH或PUCCH需要保持相位连续性和/或功率一致性。
在一个可能的实例中，所述根据所述预设时段发送资源包括：根据所述预设时段获取联合信道估计次数；根据预设参数和所述预设时间段发送资源，每次联合信道估计对应的预设参数的参数值相同。
其中，预设时段中包括有每次联合信道估计的时间，因此可以获取一个预设时段内的联合信道估计次数。一个预设时段内可以进行一次或多次的联合信道估计，每次进行联合信道估计时终端需要保持相位连续，即与相位有关的参数需要保持不变。例如在一个预设时段内包括两个时间窗，每个时间窗对应的时段内包括两个PUSCH，此时每个时间窗对应的时段内包含的两个PUSCH中的预设参数均相同，但第一个时间窗内的PUSCH中的预设参数和第二个时间窗内的PUSCH中的预设参数可以是不同的。此时若该预设时段内仅进行一次联合信道估计，则需要保持这两个时间窗内的每个PUSCH中的预设参数均相同，即此时需要选择一个目标参数值，使得预设时段内每个PUSCH中的预设参数值相同。若此时该预设时段内要进行两次联合信道估计，则仅需保持每次联合信道估计对应的时段内的PUSCH中的预设参数值相同。
在一个可能的实例中，所述预设参数包括以至少一种传输参数：调制编码 策略、频域资源位置、发射功率、发送预编码指示、时间提前命令、空间参数。
其中，频域资源位置，具体可以包含PRB的总数以及其具体频域位置。空间参数(Spatialparameter)，具体可以指的是空域波束信息。所述预设参数为与终端的相位有关的参数，包括但不限于上述提到的参数。
步骤203，网络设备在接收到来自终端发送的资源，并根据所述预设时段和所述预设资源进行联合信道估计。
可见，本实例中，终端获取来自网络设备的时间信息，所述时间信息用于确定预设时段，所述预设时段处于多个时间窗对应的时段，然后终端根据所述预设时段发送资源，网络设备接收来自终端设备的资源，并根据所述资源和所述预设时段进行联合信道估计。这样可以确定出具体的联合信道估计时间，提高信道估计效率。
本申请实施例提供一种联合信道估计装置，该联合信道估计装置可以为终端。具体的，联合信道估计装置用于执行以上联合信道估计方法中终端所执行的步骤。本申请实施例提供的联合信道估计装置可以包括相应步骤所对应的模块。
本申请实施例可以根据上述方法示例对联合信道估计装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
