其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代 理(user agent)、用户设备(user device)、或用户终端(user equipment，终端)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(vehicle to everything，V2X)中的V2V(vehicle to vehicle，车对车)通信、V2I(vehicle to Infrastructure，车对路边设备)通信和V2P(vehicle to pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving GateWay，SGW)、公用数据网网关(Public Data Network GateWay，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户服务器(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
对于蜂窝移动通信系统来説，网络的覆盖性能是至关重要的。这会直接影响运营商的网络部署。在网络部署密集的情况下，网络的覆盖性能会比较好，但是会增加运营商的成本。在网络部署稀疏的情况下，网络的覆盖性能比较差。
为了提高网络的覆盖性能，可以采用重复传输方式增强网络的覆盖性能。例如，通过时域上的重复传输，提高上行覆盖的性能。然而，时域上重复传输的方法会导致频谱资源的利用率会比较低，并且会带来额外的时延。在一些实施例中，可以通过在不同的时隙之间，或是同一个时隙内部的同一个用户的PUSCH(Physical Uplink Shared Channel，上行物理共享信道)或PUCCH(Physical Uplink Control Channel，物理上行链路控制信道)传输的DMRS进行联合信道估计来提高信道估计的准确性， 从而提高网络的覆盖性能。也就是通过支持跨时隙或者跨重复传输的DMRS绑定，来增强PUSCH以及PUCCH的覆盖质量和覆盖范围。
而针对基于跨时隙或者跨重复传输的DMRS绑定的联合信道估计，需要终端与基站等满足一定的功率一致性以及相位连续性条件。
对此，如图2所示，本公开实施例提供一种联合信道估计的配置方法，该方法被终端执行，包括：
步骤S101、接收联合信道估计的配置信息；其中，所述配置信息用于终端进行所述联合信道估计。
在本公开实施例中，终端可以从网络设备获取到联合信道估计的配置信息。这里，网络设备可以是，如基站或者核心网设备等具有与终端进行信息交互功能的设备。终端可以根据配置信息确定进行联合信道估计所需的DMRS的配置等。或者，终端可以基于配置信息确定是否进行联合信道估计，或进行联合信道估计对应的时段等。
终端通过获取网络设备提供的配置信息，进行相应的联合信道估计，可以便于终端基于满足配置信息配置的条件时进行上述联合信道估计，提升信道估计的准确性，进而提升网络的覆盖性能。
在一些实施例中，所述配置信息，至少包括：
终端进行所述联合信道估计所需DMRS绑定的时间范围信息。
DMRS广泛存在于各个通信场景的物理信道中，例如下行的PBCH(Physical Broadcast Channel，广播物理信道)、PDCCH(Physical Downlink Control Channel，物理下行控制信道)和PDSCH(Physical Downlink Shared Channel，物理下行共享信道)，以及上行的PUCCH和PUSCH等，用于上下行数据的解调。针对特定的终端，可以用于进行无线信道的信道估计。
在本公开实施例中，可以采用跨时隙或者跨重复传输的DMRS绑定， 来实现联合信道估计。也就是说，上述时间范围信息可以表示进行联合信道估计的时段跨越的多个时隙或重传范围，在该时间范围信息对应的时段内，可以采用固定的DMRS序列设定，从而便于进行联合信道估计，提升信道估计的准确性。
此外，配置信息还可以包括对DMRS时序或其他参数的配置信息，便于终端基于配置信息，根据DMRS进行联合信道估计。
在一些实施例中，如图3所示，所述方法还包括：
步骤S201、上报终端支持的DMRS绑定能力信息，其中，所述DMRS绑定能力信息用于网络设备确定所述联合信道估计的配置信息。
通过支持跨时隙或者跨重复传输的DMRS绑定来实现联合信道估计，需要终端在一定的时间范围内保持功率一致性和相位连续性，需要终端支持满足上述功率以及相位等性能的要求。因此，终端可以上报自身支持的DMRS绑定能力信息，告知网络设备自身是否支持进行联合信道估计，或者告知网络设备自身支持的功率以及相位等性能的范围。
如此，便于网络设备基于终端上报的能力进行相应的配置。如果终端上报的能力表明自身无法支持联合信道估计，则网络设备可以不进行联合信道估计的配置。若终端上报的能力表明自身可以支持上述联合信道估计，则网络设备可以提供相应的配置信息，便于终端进行联合信道估计。
在一些实施例中，所述DMRS绑定能力信息包括：
所述终端的DMRS绑定能力是否支持联合信道估计的指示信息。
在本公开实施例中，终端上报的DMRS绑定能力信息，可以用于告知网络设备终端是否支持联合信道估计。终端可以基于自身的DMRS绑定能力，确定是否支持联合信道估计。
除此之外，终端也可以根据自身的DMRS绑定能力，确定自身支持 联合信道估计的时段，并上报至网络设备。
当然，终端还可以直接将自身的DMRS绑定能力的相关参数上报至网络设备，由网络设备确定终端是否支持联合信道估计。
在一些实施例中，所述方法还包括：
基于协议的约定，确定所述终端的DMRS绑定能力是否支持联合信道估计的指示信息。
在本公开实施例中，上述终端的DMRS绑定能力信息用于指示终端是否支持联合信道估计，因此，终端可以基于自身的DMRS绑定能力判断是否支持，进而进行上报。
终端的判断标准，可以依据协议的约定确定，因此，终端可以基于协议约定，确定自身的DMRS绑定能力是否满足联合信道估计的条件。
在一些实施例中，所述DMRS绑定能力，包括以下一种或多种：
所述终端的功率一致性；以及
所述终端的相位连续性；
上述DMRS绑定能力可以包括终端支持的功率以及相位等参数的能力，示例性地，终端基于协议规定的阈值范围，确定自身的上述DMRS绑定能力是否满足联合信道估计所需满足的功率一致性以及相位连续性要求，并上报网络设备，从而便于网络设备基于终端的上报进行相应的配置。
在本公开实施例中，协议可以规定终端需要同时满足功率一致性条件和相位连续性条件，即终端的功率满足预定的功率一致性条件，且同时相位满足预定的相位连续性条件，从而满足联合信道估计的条件。
上述DMRS绑定能力，包括以下一种或多种：
所述终端支持的功率最大值和最小值；
所述终端的功率在预定时长范围内波动偏差的最大绝对值；以及
所述终端的功率在预定时长范围内波动偏差的标准差或方差值。
上述功率一致信息可以从终端支持的功率的范围，以及功率波动的范围等方面表示。终端可以通过判断上述终端支持的功率最大值、最小值以及波动偏差等是否满足联合信道估计所需的阈值条件，进而判断终端是否满足进行联合信道估计的需求。
需要说明的是，上述功率一致信息是否满足联合信道估计的需求可以通过协议约定。因此，终端也可基于自身的功率一致信息确定是否满足联合信道估计的需求，并上报至网络设备，以供网络设备进行相应的配置。
示例性地，协议可以预先约定终端进行联合信道估计的一定时间范围功率的最小值和最大值；一定时间范围功率波动相对偏差最大绝对值；以及一定时间范围内功率波动方差或者标准差的最大值等。如此，可以基于终端的功率一致信息是否满足协议约定的范围确定终端是否满足联合信道估计的条件。
上述DMRS绑定能力，还可以包括以下一种或多种：
所述终端支持的相位最大值和最小值；
所述终端的相位在预定时长范围内波动偏差的最大绝对值；以及
所述终端的相位在预定时长范围内波动偏差的标准差或方差值。
与功率一致性的相关参数类似，终端可以通过确定终端支持的相位最大值、最小值以及波动偏差等是否满足联合信道估计所需的阈值条件，上报自身的能力，从而便于网络设备下发相应的配置信息。
当然，相位连续信息满足联合信道估计的需求也可通过协议约定。因此，终端也可基于自身的相位一致性的相关参数确定是否满足协议规定的阈值条件，并上报至网络设备，以供网络设备进行相应的配置。
示例性地，协议可以预先约定终端进行联合信道估计的一定时间范 围相位的最小值和最大值；一定时间范围相位波动相对偏差最大绝对值；以及一定时间范围内相位波动方差或者标准差的最大值等。如此，可以基于终端的相位连续信息是否满足协议约定的范围确定终端是否满足联合信道估计的条件。
在一些实施例中，所述上报终端支持的DMRS绑定能力信息，包括：
上报携带有所述DMRS绑定能力信息的终端能力上报信息。
在本公开实施例中，终端可以将上述DMRS绑定能力信息携带在终端能力上报信息中，并上报至网络设备。终端能力上报信息还可以用于携带终端的其他能力，因此，网络设备可以基于终端能力上报信息确定上述联合信道估计的配置信息，同时还可以进行其他信息的配置以及终端进行数据传输的资源调度等等。
如此，终端上报DMRS绑定能力信息不需要进行额外的信令传输，利用已有的终端能力上报信息就可以进行上报。
在一些实施例中，所述上报终端支持的DMRS绑定能力信息，包括：
上报用于指示所述DMRS绑定能力信息的辅助信息。
在本公开实施例中，可以通过辅助信息来上报终端的DMRS绑定能力信息。辅助信息可以作为单独的信令上报，也可以携带在其他已有的信令上报。可以通过显示地信息携带在信令中，也可以通过通过其他信息进行隐式地指示。
在一些实施例中，所述上报用于指示所述DMRS绑定能力信息的辅助信息，包括：
显式地上报携带有所述辅助信息的专用信息；或
隐式地上报携带有所述辅助信息的预定信息。
这里，专用信息可以包括携带在预定信令的专用信息域的辅助信息或携带在专用信令中的辅助信息专用信息可以专用于携带上述辅助信 息，辅助信息的内容可以包括终端的DMRS能力信息。通过专用信息上报终端的DMRS绑定能力，可以便于网络设备确定终端进行联合信道估计的配置信息。
此外，预定信息可以是用于上报其他内容的信息，而并非专用于上报该辅助信息的信令。隐式地携带即利用预定信息原有的信息内容、信令格式、编码方式、加扰方式以及重传次数等等信息的不同情况来隐式地表示终端上报的辅助信息。示例性地，上述辅助信息可以包括指示终端的DMRS绑定能力是否满足进行联合信道估计的条件。如果终端的DMRS绑定能力满足联合信道估计的条件，则通过预定信息的第一编码方式上报；若终端的DMRS绑定能力不满足联合信道估计的条件，则通过预定信息的第二编码方式进行上报。如此，网络设备只需要通过预定信息的编码方式，就可以确定终端的DMRS绑定能力是否满足联合信道估计的条件，进而提供对应的配置信息。
在一些实施例中，所述方法还包括：
基于接收到的所述联合信道估计的配置信息，进行所述联合信道估计。
终端在接收到网络设备提供的配置信息后，可以基于网络设备的调度，进行上行传输，并在上行传输的过程中，基于该配置信息，进行相应的联合信道估计。
如图4所示，本公开实施例提供一种联合信道估计的配置方法，该方法被网络设备执行，包括：
步骤S301、下发终端进行联合信道估计的配置信息；其中，所述配置信息用于终端进行所述联合信道估计。
在本公开实施例中，网络设备可以对终端进行联合信道估计的配置，因此向终端下发相应的配置信息。这里，网络设备可以是，如基站或者 核心网设备等具有与终端进行信息交互功能的设备。如此，终端可以基于配置信息进行联合信道估计。例如，终端可以根据配置信息确定进行联合信道估计的DMRS的配置等，并基于DMRS进行联合信道估计。或者，终端可以基于配置信息确定是否进行联合信道估计，或进行联合信道估计对应的时段等。
网络设备提供配置信息，便于终端在满足联合信道估计的条件下进行相应的联合信道估计，从而提升信道估计的准确性，进而提升网络的覆盖性能。
在一些实施例中，所述配置信息，至少包括：
终端进行所述联合信道估计所需DMRS绑定的时间范围信息。
DMRS广泛存在于各个通信场景的物理信道中，例如下行的PBCH、PDCCH和PDSCH，以及上行的PUCCH和PUSCH等，用于上下行数据的解调。针对特定的终端，可以用于进行无线信道的信道估计。
在本公开实施例中，可以采用跨时隙或者跨重复传输的DMRS绑定，来实现联合信道估计。也就是说，上述时间范围信息可以表示进行联合信道估计的时段跨越的多个时隙或重传范围，在该时间范围信息对应的时段内，可以采用固定的DMRS序列设定，从而便于进行联合信道估计，提升信道估计的准确性。
在一些实施例中，下发的所述配置信息包括N套，其中，N为大于或等于1的整数。
在本公开实施例中，网络设备可以为终端配置一套或者多套配置信息，终端可以在不同的情况下使用不同的配置信息进行联合信道估计。此外，网络设备也可以为多个终端配置相同的配置信息或者不同的配置信息，例如，对小区内的所有终端配置相同的配置信息，或者对分组的终端配置相同的配置信息。
在本公开实施例中，网络设备对终端进行联合信道估计的配置信息可以基于不同的配置粒度进行对应的配置。具体地，网络设备可以基于不同的SCS、PUCCH、PUSCH、业务类型、调频模式、DMRS模式或者终端上报的不同DRMS绑定能力信息中的一种或多种不同信息作为配置的粒度，并对应确定N套配置信息，N可以为一套也可以为多套，并下发所述N套配置信息。
终端则可以基于网络设备的配置，激活上述N套配置信息中的一套或者多套，并在进行联合信道估计的过程中使用激活的配置信息。
在一些实施例中，如图5所示，所述方法还包括：
步骤S401、下发激活所述配置信息的激活信息，其中，所述激活信息用于激活终端支持M套配置信息，所述M为小于或等于N的正整数。
网络设备还可以通过下发激活信息的方法，触发对终端生效的配置信息，例如，通过激活信息触发终端在同一时段内可以支持M套配置信息，则终端可以基于传输的情况利用被激活的配置信息进行对应的联合信道估计。
当然，网络设备下发激活信息激活的配置信息数量不大于网络设备下发的配置信息的总数量。这样，网络设备可以基于不同的参数为终端配置多套配置信息，然后基于不同的需求或者传输状态激活其中的至少部分配置信息，而不需要进行反复配置。
在一些实施例中，所述下发激活所述配置信息的激活信息，包括：
通过DCI或MAC-CE下发所述配置信息的激活信息。
上述激活信息可以通过DCI或者MAC-CE等信息下发，通过新增的信息域携带上述激活信息，告知终端被激活的配置信息包括哪些，从而便于终端确定当前可以使用的配置信息。
在一些实施例中，所述下发终端进行联合信道估计的配置信息，包 括：
通过无线资源控制RRC信令下发所述配置信息。
基站可以通过RRC信令携带配置信息并下发至终端，也可以通过其他信令携带配置信息下发至终端。例如，通过RRC半静态配置、RRC预配置结合DCI指示激活的方式，或者通过MAC预配置并结合DCI指示激活等显式指示的方式。
在一些实施例中，如图6所示，所述方法还包括：
步骤S501、接收终端上报的DMRS绑定能力信息；
步骤S502、根据所述DMRS绑定能力信息，确定所述联合信道估计的配置信息。
通过支持跨时隙或者跨重复传输的DMRS绑定来实现联合信道估计，需要终端在一定的时间范围内保持功率一致性和相位连续性，需要终端支持满足上述功率以及相位等性能的要求。因此，网络设备可以通过获取终端支持的DMRS绑定能力信息，确定终端是否支持进行联合信道估计，或者获取终端支持的功率以及相位等性能的范围。
如此，网络设备可以基于终端上报的能力进行相应的配置。若网络设备获取的终端能力表明该终端无法支持联合信道估计，则网络设备可以不进行联合信道估计的配置。若网络设备获取的终端能力表明该终端可以支持上述联合信道估计，则网络设备可以提供相应的配置信息，便于终端进行联合信道估计。
在一些实施例中，所述下发终端进行联合信道估计的配置信息，包括：
响应于所述DMRS绑定能力信息指示终端满足联合信道估计的条件，确定终端进行联合信道估计的配置信息；或
确定所述DMRS绑定能力信息是否满足协议约定的阈值范围；响应 于所述DMRS绑定能力信息满足协议预定的阈值范围，确定终端进行联合信道估计的配置信息。
在本公开实施例中，可以通过协议约定终端进行联合信道估计所需满足的条件，包括相位及功率的限定等。
示例性地，协议可以约定终端需满足一定时间范围内相位的最大值和最小值、功率的最大值和最小值；一定时间范围内相位波动的相对偏差的最大绝对值、功率波动的相对偏差的最大绝对值；以及一定时间范围内相位波动的方差或标准差的最大值、功率波动的方差或者标准差的最大值等。
如果终端上报的DMRS绑定能力信息表明终端满足协议约定的上述阈值范围，则可以进行联合信道估计，因此可以下发终端进行联合信道估计的配置信息。
在本公开实施例中，若终端上报的DMRS绑定能力信息用于指示终端是否满足联合信道估计的条件，或者终端支持联合信道估计的时段，则网络设备在DMRS绑定能力信息指示终端满足条件时确定相应的配置信息，而在DMRS绑定能力信息指示终端不满足条件时，确定不对终端进行配置。
若终端上报的DMRS绑定能力信息用于告知网络设备终端的能力参数，则网络设备可以基于协议的约定，确定终端上报的能力参数是否满足联合信道估计规定的阈值条件，进而进行相应的配置。
在一些实施例中，所述方法还包括：
响应于终端满足预定条件，调度终端的上行信道传输；其中，所述终端在所述上行信道传输的过程中，基于所述配置信息，进行联合信道估计。
网络设备可以在终端满足预定条件时，调度终端的上行信道传输。 这里的预定条件为终端进行联合信道估计所需满足的条件。终端基于网络设备的调度，进行上行传输，并可以在上行传输的过程中，基于网络设备提供的配置信息进行联合信道估计，从而提升信道估计的准确性，提升网络覆盖性能。
在一些实施例中，所述预定条件包括但不限于以下至少之一：
所述终端支持跨时隙或跨重复传输的上行信道传输；
所述终端上行信道位于固定的频域位置；以及
所述终端采用预编码方式、TBS(Transport block size，传输块大小)调制方式和固定波束。
也就是终端支持进行上述联合信道估计，同时可以满足上行信道的频域位置、预编码方式、TBS的调制方式以及波束均固定不变，从而便于进行上述联合信道估计。
在一些实施例中，所述下发终端进行联合信道估计的配置信息，包括：
下发显式地携带所述配置信息的第二专用信息；其中，所述第二专用信息包括携带在预定信令的专用信息域的配置信息或携带在专用信令中的配置信息；或
下发隐式地携带所述配置信息的第二预定信息。
在本公开实施例中，可以通过显示指示的方式，向终端下发上述配置信息。例如，通过将配置信息携带在新增的专用信令中下发至终端，或者在已有的预定信令中，新增专用信息域携带上述配置信息下发至终端。
此外，也可以通过隐式指示的方式下发上述配置信息，例如，通过TDRA(Time Domain Resource Assignment，时域资源分配)索引隐式指示配置信息，或者通过重传次数隐式指示配置信息，又如通过PUCCH资 源隐式指示配置信息。也就是说，通过已有信息中具有可变性的内容、格式、数量等参数与配置信息所要提供的内容关联并发送至终端。如此，终端只要通过预定的规则就可以通过接收到的信息确定出网络设备提供的配置信息。如此，不需要额外的信令开销，也不需要新增改变已有信令的格式等，适用范围更广。
本公开实施例还提供如下示例：
在本公开实施例中，针对支持联合信道估计或者DMRS绑定的阈值或者默认条件的配置：
1、可以通过协议规定支持联合信道估计或者DMRS绑定的相位和功率限定。示例性地，规定一定时间范围相位最大值和最小值以及功率最大值和最小值；规定一定时间范围相位波动或功率波动相对偏差最大绝对值；以及规定一定时间范围内相位波动或功率波动方差(或标准差)的最大值等。
2、终端可以上报自身的能力或者辅助信息。也就是说，终端可以上报对于自身功率一致性以及相位连续性的支持情况。
示例性地，终端可以将其功率一致性以及相位连续性的信息作为自身能力进行上报；或者将其功率一致性以及相位连续性的信息作为辅助信息，通过物理层或者高层专用信息显式地上报；或者将其功率一致性以及相位连续性的信息作为辅助信息，利用已有信息隐式地上报。
3、基站的调度可以满足以下条件：

频域位置相同，不发生时隙间或者时隙内的跳频；

在本公开实施例中，针对支持联合信道估计或者DMRS绑定的触发机制和配置原则：
基站可以针对单个终端进行单独触发或者单独配置，基站也可以针对多个终端(如分组内的所有终端或者小区内所有终端)进行联合触发或者联合配置。当进行联合触发时，被触发的所有终端都满足并可以上报终端支持的功率一致性和相位连续性信息。
此外，基站可以对同一终端配置一套或多套配置信息，配置的粒度可以基于如下信息的不同情况进行配置：
1、针对不同SCS配置；

3、针对不同业务类型配置；
4、针对不同重传次数配置；
