具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图1是根据本公开的实施例示出的一种物理下行控制信道发送方法的示意流程图。本实施例所示的物理下行控制信道发送方法可以适用于基站，所述基站包括但不限于5G基站、6G基站等通信***中的基站。所述基站可以与作为用户设备的终端进行通信，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。在一个实施例中，所述终端可以是后续任一实施例所述物理下行控制信道接收方法所适用的终端。
在一个实施例中，在所述基站中设置有多个发送单元，所述发送单元可以是天线面板panel，也可以是传输接收点TRP(Transmission Reception Point)。基站可以选择通过多个发送单元发送PDCCH，也可以选择其中某个发送单元单独发送PDCCH，具体可以根据基站需要设置。
如图1所示，所述物理下行控制信道发送方法可以包括以下步骤：
在步骤S101中，通过多个发送单元向终端发送物理下行控制信道PDCCH，其中，不同所述发送单元发送的PDCCH的解调参考信号DMRS序列不同。
在一个实施例中，基站可以通过多个发送单元向终端发送PDCCH，也即每个发送单元都可以向终端发送PDCCH。
其中，每个发送单元可以在相同的时频资源向终端发送PDCCH，也可以在不同的时频资源向终端发送PDCCH，具体可以由基站根据需要选择。
每个发送单元与终端之间都可以形成一条通信链路，从而多个发送单元与终端之间可以形成多条通信链路，基站就可以通过该多条通信链路向终端发送PDCCH。
据此，即使多个发送单元中某个发送单元与终端之间的通信链路因被遮挡、深度衰落等原因而受到影响，由于多个发送单元中的其他发送单元与终端之间还存在通 信链路来发送PDCCH，因此可以确保顺利地将PDCCH发送至终端，有利于提高发送PDCCH的可靠性，尤其在高频带上，可以增加PDCCH的鲁棒性，以便满足URLLC(Ultra-relaible and Low Latency Communication，极可靠低时延通信)业务的需要。
另外，由于不同的发送单元发送的PDCCH所经过的无线信道不同，使得终端在接收到PDCCH后，可以基于不同的DMRS序列配置分别估计相应的无线信道并进一步解调PDCCH。
需要说明的是，不同的发送单元在空间上可以处于不同位置，也可以处于相同位置，在不同的发送单元在空间上处于相同位置的情况下，不同的发送单元发送信号的方向可以不同，例如发送波束的方向不同。
图2是根据本公开的实施例示出的另一种物理下行控制信道发送方法的示意流程图。如图2所示，所述方法还包括：
在步骤S201中，针对每个所述发送单元分别确定初始化参数；
在步骤S202中，根据所述初始化参数和伪随机序列确定所述发送单元发送的PDCCH的DMRS序列。
在一个实施例中，DMRS序列可以通过伪随机序列确定，生成伪随机序列的函数需要初始化，所述函数包括但不限于GOLD序列生成函数，对函数进行初始化得到的参数即初始化参数，进而可以根据初始化参数和伪随机序列确定DMRS序列，具体可以是根据初始化参数确定用于生成伪随机序列的函数，然后根据该函数和待生成的DMRS序列的序号来确定DMRS序列。
根据本实施例，可以针对每个发送单元分配确定初始化参数，从而可以针对不同的发送单元可以得到不同的初始化参数，进而根据不同的初始化参数可以得到不同的伪随机序列，最后基于不同的伪随机序列可以得到不同的DMRS序列，从而实现了针对不同发送单元发送的PDCCH确定不同的DMRS序列，进而保证不同发送单元发送的PDCCH的DMRS序列不同。
图3是根据本公开的实施例示出的又一种物理下行控制信道发送方法的示意流程图。如图3所示，所述针对每个所述发送单元分别确定的初始化参数包括：
在步骤S301中，针对不同的所述发送单元确定不同的扰码；
在步骤S302中，根据所述扰码确定相应发送单元的伪随机序列中的初始化参 数；
在步骤S303中，将所述扰码配置给所述终端。
在一个实施例中，初始化参数可以基于扰码得到，基站可以将用于确定初始化参数的扰码配置给终端，例如通过无线资源控制RRC(Radio Resource Control)信令将扰码配置给终端，以便终端可以基于接收到的扰码确定初始化参数，从而确定伪随机序列对应的DMRS，进而根据DMRS序列解调PDCCH。
在一个实施例中，初始化参数可以参考下式确定：

其中，l表示时域上符号的位置；c init是GOLD序列生成函数的初始化参数；

是一个时隙slot所包含符号symbol的数目，例如可以为14；N IDk为扰码，其中的k是发送单元的相关信息，也即针对不同的发送单元，可以设置不同的扰码N IDk，从而可以得到不同的初始化参数，进而得到不同的DMRS序列，每个N IDk的取值范围可以是0到65535，

在一个实施例中，DMRS序列可以参考下式确定：
Figure PCTCN2020117210-appb-000004
其中，l表示时域上符号的位置；c()是GOLD序列生成函数，c(2m)和c(2m+1)都可以视作不同的GOLD序列；m是DMRS序列的序号。根据该伪随机序列，可以生成在符号l上映射的DMRS序列。
图4是根据本公开的实施例示出的又一种物理下行控制信道发送方法的示意流程图。如图4所示，所述针对每个所述发送单元分别确定的初始化参数包括：
在步骤S401中，响应于不给所述终端配置所述发送单元对应的扰码，根据所述基站对应小区的标识和所述发送单元的相关信息确定扰码；
在步骤S402中，根据所述扰码确定相应发送单元的伪随机序列中的初始化参数。
在一个实施例中，在基站不给终端配置发送单元对应的扰码时，终端就不能根据基站配置的扰码来确定DMRS序列，基站和终端可以预先约定在这种情况下，基于 能够获取到的信息确定扰码，例如根据基站对应小区的标识和发送单元的相关信息确定扰码。
对于基站而言，基站可以确定自身对应小区的标识，以及自身发送单元的相关信息。对于终端而言，终端在接收到基站发送的信息(包括但不限于所述PDCCH)后，可以确定基站对应小区的标识，另外基站在通过发送单元发送PDCCH时，还可以携带发送单元的相关信息，终端在接收到PDCCH后，可以确定发送该PDCCH的发送单元的相关信息，从而根据基站对应小区的标识和发送单元的相关信息确定扰码，进而根据扰码确定DMRS序列。
在一个实施例中，初始化参数可以参考下式确定：
Figure PCTCN2020117210-appb-000005
其中，l表示时域上符号的位置；
Figure PCTCN2020117210-appb-000006

是无线帧内的时隙号；N ID为扰码，
Figure PCTCN2020117210-appb-000008
为基站对应小区的标识，k为发送单元的相关信息，据此，针对不同的发送单元而言，发送单元的相关信息可以不同，扰码N ID就可以不同，也即针对不同的发送单元，可以设置不同的扰码N ID，从而可以得到不同的初始化参数，进而得到不同的DMRS序列，每个N ID的取值范围可以是0到65535。
图5是根据本公开的实施例示出的又一种物理下行控制信道发送方法的示意流程图。如图5所示，所述针对每个所述发送单元分别确定的初始化参数包括：
在步骤S501中，根据所述发送单元的相关信息确定用于计算所述初始化参数的函数；例如根据所述发送单元的相关信息、时隙包含符号的数目、符号的位置、无线帧内的时隙号和扰码确定用于计算所述初始化参数的函数。
在一个实施例中，所述初始化参数需要基于函数确定，例如在前述实施例中，所述函数为：
Figure PCTCN2020117210-appb-000009
或者为：
Figure PCTCN2020117210-appb-000010
函数计算公式中各参量的含义同图3和图4实施例部分的参数，在此不一一赘 述！
在这两个实施例中，计算初始化参数的函数并没有发生改变。
在本实施例，可以对计算初始化参数的函数进行调整，具体可以根据所述发送单元的相关信息、时隙包含符号的数目、符号的位置、无线帧内的时隙号和扰码确定用于计算所述初始化参数的函数，例如在上述函数中以加法关系(也可以采用其他关系，例如与扰码相乘的关系)添加发送单元的相关信息k，那么计算初始化参数的函数可以如下所示：
Figure PCTCN2020117210-appb-000011
函数计算公式中各参量的含义同图3和图4实施例部分的参数，在此不一一赘述！
据此，针对不同的发送单元而言，发送单元的相关信息k可以有所不同，从而针对不同的发送单元而言，用于计算初始化参数的函数有所不同，那么计算得到初始化参数就可以有所不同，也即针对不同的发送单元，可以得到不同的初始化参数，进而得到不同的DMRS序列。
需要说明的是，在所有实施例中，发送单元的相关信息，包括但不限于发送单元的标识、序号、针对发送单元生成的随机数等。
图6是根据本公开的实施例示出的又一种物理下行控制信道发送方法的示意流程图。如图6所示，所述通过多个发送单元向终端发送PDCCH包括：
在步骤S601中，通过多个发送单元在相同的时频资源向终端发送PDCCH。
在一个实施例中，多个发送单元可以在相同的时频资源向终端发送PDCCH，也即多个发送单元可以空分复用SDM(Space Division Multiplexing)，相应地，终端可以通过多个接收单元在相同的时频资源接收基站发送的多个PDCCH，虽然在相同的时频资源接收到多个PDCCH，但是不同的PDCCH中的DMRS序列不同，因此可以确保终端基于不同的DMRS序列分别解调不同DMRS序列对应的PDCCH。
图7是根据本公开的实施例示出的又一种物理下行控制信道发送方法的示意流程图。如图7所示，所述通过多个发送单元向终端发送PDCCH包括：
在步骤S701中，通过多个发送单元在同一个DMRS端口向终端发送PDCCH。
在一个实施例中，多个发送单元可以在同一个DMRS端口(例如端口2000) 向终端发送PDCCH，据此，可以确保满足当前协议对于PDCCH仅支持单端口传输的要求。而多个发送单元发送的多个PDCCH中的DMRS序列不同，可以视作是在非正交(也可以称作准正交)的多个DMRS端口上发送的。
据此，可以保证虽然发送的DMRS序列不同，但是在时域和频域上映射的位置却是相同的。例如图8所示，多个DMRS序列在时域和频域上映射的位置相同，都是每隔3个数据的资源粒子RE(Resource Element)映射一个DMRS的RE，在PDCCH中，数据的RE中内容可以是DCI。也即基站在相同的时频位置发送PDCCH中DMRS的RE和数据的RE。
例如可以参考下式进行DMRS在时频资源上的映射：
Figure PCTCN2020117210-appb-000012
Figure PCTCN2020117210-appb-000013
k′＝0,1,2；
n＝0,1,...
其中，
Figure PCTCN2020117210-appb-000014
是DMRS序列在时频资源上的RE位置，
Figure PCTCN2020117210-appb-000015
是功率调整因子，r l是DMRS序列，k′是DMRS序列中的序列值序号，
Figure PCTCN2020117210-appb-000016
是一个PRB中包含子载波的数量，例如为12。
可选地，每个所述发送单元向终端发送的PDCCH中的下行控制信息DCI相同。
在一个实施例中，每个发送单元向终端发送的PDCCH中的DCI可以是相同的，据此，即使多个发送单元中某个发送单元与终端之间的通信链路因被遮挡、深度衰落等原因而受到影响，由于多个发送单元中的其他发送单元与终端之间还存在通信链路来发送PDCCH，因此可以提高PDCCH发送链路的有效性，保证更高的接收可靠性，使得终端能够从PDCCH中获取到DCI。
可选地，每个所述发送单元向终端发送的PDCCH中携带DCI的部分信息，且所述多个发送单元向终端发送的PDCCH中携带的DCI的部分信息构成完整的DCI。
在一个实施例中，每个发送单元向终端发送的PDCCH中可以携带DCI的部分信息，并且多个发送单元向终端发送的PDCCH中携带的DCI的部分信息可以构成完整的DCI。
例如对于3个发送单元而言，可以将一个完整的DCI编码后划分为3个部分， 其中第一部分通过第一个发送单元发送的PDCCH承载，第二部分通过第二个发送单元发送的PDCCH承载，第三部分通过第三个发送单元发送的PDCCH承载，据此，可以提高发送DCI的灵活性，并且及时在DCI的数据量较大的情况下，也可以将DCI划分为多个数据量较小的部分分别发送。
图9是根据本公开的实施例示出的一种物理下行控制信道接收方法的示意流程图。本实施例所示的物理下行控制信道接收方法可以适用于终端，所述终端包括但不限于手机、平板电脑、可穿戴设备、传感器、物联网设备等电子设备。所述终端可以作为用户设备与基站通信，所述基站包括但不限于5G基站、6G基站等通信***中的基站。在一个实施例中，所述基站可以是上述任一实施例所述的物理下行控制信道发送方法所适用的基站。
在一个实施例中，在所述终端中设置可以有多个接收单元，例如多个接收天线，每个接收天线都可以接收基站发送的下行控制信道。
如图9所示，所述物理下行控制信道接收方法可以包括以下步骤：
在步骤S901中，通过所述多个接收单元接收基站中多个发送单元发送的PDCCH，其中，不同所述发送单元发送的PDCCH的解调参考信号DMRS序列不同。
在一个实施例中，基站可以通过多个发送单元向终端发送PDCCH，也即每个发送单元都可以向终端发送PDCCH，相应地，终端可以通过多个接收单元接收基站中多个发送单元发送的PDCCH，不同接收单元接收的PDCCH的DMRS序列也不同。
其中，每个发送单元可以在相同的时频资源向终端发送PDCCH，也可以在不同的时频资源向终端发送PDCCH，具体可以由基站根据需要选择。
每个发送单元与接收单元之间都可以形成一条通信链路，从而多个发送单元与多个接收单元之间可以形成多条通信链路，基站就可以通过该多条通信链路向终端发送PDCCH。
据此，即使多个发送单元中某个发送单元与终端之间的通信链路因被遮挡、深度衰落等原因而受到影响，由于多个发送单元中的其他发送单元与终端之间还存在通信链路来发送PDCCH，因此可以确保顺利地将PDCCH发送至终端，有利于提高发送PDCCH的可靠性。
另外，由于不同的发送单元发送的PDCCH所经过的无线信道不同，使得终端在接收到PDCCH后，可以基于不同的DMRS序列配置分别估计相应的无线信道并进 一步解调PDCCH。
图10是根据本公开的实施例示出的另一种物理下行控制信道接收方法的示意流程图。如图10所示，所述方法还包括：
在步骤S1001中，确定每个所述发送单元发送的PDCCH分别对应的初始化参数；
在步骤S1002中，根据所述初始化参数和伪随机序列确定对应的所述发送单元发送的PDCCH的DMRS序列。
在一个实施例中，由于基站针对每个发送单元分配确定初始化参数，从而针对不同的发送单元可以得到不同的初始化参数。那么终端在接收到多个PDCCH轴，可以确定每个发送单元发送的PDCCH分别对应的初始化参数，并且确定的不同的发送单元对应的初始化参数不同，进而可以基于不同的初始化参数和伪随机序列确定所述发送单元发送的PDCCH的DMRS序列，具体可以是根据初始化参数确定用于生成伪随机序列的函数，然后根据该函数和待生成的DMRS序列的序号来确定DMRS序列，从而基于不同的初始化参数得到不同的DMRS序列，以对每个PDCCH进行解调。
图11是根据本公开的实施例示出的又一种物理下行控制信道接收方法的示意流程图。如图11所示，所述确定每个所述发送单元发送的PDCCH分别对应的初始化参数包括：
在步骤S1101中，根据所述基站发送的配置信息确定每个所述发送单元对应的扰码，其中，不同的所述发送单元对应的扰码不同；
在步骤S1102中，根据所述扰码确定相应发送单元的伪随机序列中的初始化参数。
在一个实施例中，初始化参数可以基于扰码得到，基站可以将用于确定初始化参数的扰码配置给终端，例如通过无线资源控制RRC信令将扰码配置给终端，从而终端可以基于接收到的扰码确定初始化参数，从而确定伪随机序列对应的DMRS，进而根据DMRS序列解调PDCCH。
在一个实施例中，初始化参数可以参考下式确定：

其中，l表示时域上符号的位置；c init是GOLD序列生成函数的初始化参数；

是一个时隙slot所包含符号symbol的数目，例如可以为14；N IDk为扰码，其中的k是发送单元的相关信息，也即针对不同的发送单元，可以设置不同的扰码N IDk，从而可以得到不同的初始化参数，进而得到不同的DMRS序列，每个N IDk的取值范围可以是0到65535，
Figure PCTCN2020117210-appb-000019

基站可以将N IDk配置给终端，从而使得终端在接收到具有相关信息k的发送单元发送的PDCCH后，能够根据扰码N IDk来确定该发送单元对应的初始化参数，进而确定该发送单元发送的PDCCH中的DMRS序列。
在一个实施例中，DMRS序列可以参考下式确定：
Figure PCTCN2020117210-appb-000020
其中，l表示时域上符号的位置；c()是GOLD序列生成函数，c(2m)和c(2m+1)都可以视作不同的GOLD序列；m是DMRS序列的序号。根据该伪随机序列，可以生成在符号l上映射的DMRS序列。
图12是根据本公开的实施例示出的又一种物理下行控制信道接收方法的示意流程图。如图12所示，所述确定每个所述发送单元发送的PDCCH分别对应的初始化参数包括：
在步骤S1201中，响应于所述基站不给所述终端配置所述发送单元对应的扰码，根据所述基站对应小区的标识和所述发送单元的相关信息确定扰码；
在步骤S1202中，根据所述扰码确定相应发送单元的伪随机序列中的初始化参数。
在一个实施例中，在基站不给终端配置发送单元对应的扰码时，终端就不能根据基站配置的扰码来确定DMRS序列，基站和终端可以预先约定在这种情况下，基于能够获取到的信息确定扰码，例如根据基站对应小区的标识和发送单元的相关信息确定扰码。
对于终端而言，终端在接收到基站发送的信息(包括但不限于所述PDCCH)后，可以确定基站对应小区的标识，另外基站在通过发送单元发送PDCCH时，还可以携带发送单元的相关信息，终端在接收到PDCCH后，可以确定发送该PDCCH的发送单元的相关信息，从而根据基站对应小区的标识和发送单元的相关信息确定扰码， 进而根据扰码确定DMRS序列。
在一个实施例中，初始化参数可以参考下式确定：

相应地，终端在接收到具有相关信息k的发送单元发送的PDCCH后，可以根据基站对应小区的标识和k来确定扰码N ID，从而根据扰码N ID来确定该发送单元对应的初始化参数，进而确定该发送单元发送的PDCCH中的DMRS序列。
图13是根据本公开的实施例示出的又一种物理下行控制信道接收方法的示意流程图。如图13所示，所述确定每个所述发送单元发送的PDCCH分别对应的初始化参数包括：

在步骤S1302中，根据所述函数计算所述初始化参数。
在一个实施例中，基站可以对计算初始化参数的函数进行调整，具体了哟根据所述发送单元的相关信息、时隙包含符号的数目、符号的位置、无线帧内的时隙号和扰码确定用于计算所述初始化参数的函数，例如在上述函数中以加法关系(也可以采用其他关系，例如与扰码相乘的关系)添加发送单元的相关信息k，那么计算初始化参数的函数可以如下所示：
Figure PCTCN2020117210-appb-000025
函数计算公式中各参量的含义同图11和图12实施例部分的参数，在此不一一赘述！
据此，针对不同的发送单元而言，发送单元的相关信息k可以有所不同，从而针对不同的发送单元而言，用于计算初始化参数的函数有所不同，那么计算得到初始化参数就可以有所不同，也即针对不同的发送单元，可以得到不同的初始化参数，进而得到不同的DMRS序列。
对于终端而言，在接收到发送单元发送的PDCCH后，还可以获取到发送单元的相关信息，那么可以根据发送单元的相关信息确定用于计算初始化参数的函数，从而根据该函数计算出发送单元对应的初始化参数，进而确定该发送单元发送的PDCCH中的DMRS序列。
