Description

信号处理方法、设备及计算机可读存储介质 技术领域
本申请涉及通信技术，尤其涉及一种信号处理方法、设备及计算机可读存储介质。
背景技术
目前，5G(第五代移动通信系统)的研发和应用较多。由于5G的数据传输速度更快，有很多应用场景需要应用5G技术，这也促进了5G的发展。
其中，5G采用的频谱频率较高，在较高频谱情况下，由于一个网络节点(例如基站)覆盖范围有限，小区覆盖半径会非常小，因此在5G中一般会引入多个网络节点。例如引入了TRP(Transmission Reception Point，传输接收点)的概念，通过增加网络空口发射节点数增加网络覆盖。
但是，在基于多DCI(downlink control information，下行控制信息)调度多TRP/panel(TRP的天线阵可以分为若干相对独立的子阵Panel)的PDSCH(Physical Downlink Sharing Channel，物理下行共享信道)的场景中，终端设备能够收到不同的TRP/panel发送的信号，终端设备如何确定出该信号的发送端是哪个TRP/panel，是本领域技术人员亟需解决的技术问题。

具体实施方式
目前，很多小区内设置有多个TRP/panel，从而增大小区的覆盖半径。在基于多DCI调度多TRP/panel的PDSCH的场景中，如果多个TRP/panel之间的空间位置距离较远，或者信号传播路径隔离度很好，终端设备可以接收到两个完全不相关的的信号，即NCJT(non-coherent Joint Transmission，非相干联合传输)场景。
在NCJT场景下，不同的TRP/panel分别向终端设备发送完全不相关的信号，这种情况下，终端设备无法识别接收的信号是哪个TRP/panel发送的，进而导致无法向发送信号的TRP/panel进行响应。
本申请提供的方案中，向终端设备发送信号时，根据传输接收点对应的扰码序列对该待发送的信号进行加扰处理，得到加扰信号。终端设备接收到该加扰信号后，可以利用与其连接的传输接收点对应扰码序列对加扰信号进行解扰，从而可以根据解扰结果确定出发送加扰信号的传输接收点。这种方 式简单易行，能够使终端设备有效识别与接收的信号对应的发送源。
下面结合附图，对本申请的一些实施方式进行说明。在各实施例之间不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
图1为本申请一应用场景图。
本申请提供的方法可以应用在网络设备(如基站)中，例如图1中所示出的设置有多个传输接收点的网络设备13。
如图1所示，终端设备11可以同时连接多个传输接收点12，这些传输接收点12可以基于独立的物理下行共享信道(Physical Downlink Sharing Channel，PDSCH)向终端设备发送信号。
其中，在该通信系统中，这些传输接收点12可以设置在同一网络设备13上。网络设备13可以通过其上设置的传输接收点12向连接的终端设备11发送信号。
网络设备13可以确定其上设置的各个传输接收点12对应的扰码序列，传输接收点12可以对待发送的信号进行加扰，再将得到的加扰信号发送给终端设备11。
图2为本申请第一示例性实施例示出的信号处理方法的流程图。
如图2所示，本申请提供的方法可以包括：
步骤201，根据与传输接收点对应的扰码序列对待发送给终端设备的信号进行加扰，得到加扰信号。
其中，网络设备在向终端设备发送信号时，可以先对待发送的信号进行加扰。
具体的，当网络设备设置有多个传输接收点时，可以利用其中与终端设备连接的任一个传输接收点向终端设备发送信号。这种情况下，网络设备可以基于发送信号的传输接收点对应的扰码序列对待发送给终端设备的信号进行加扰，得到加扰信号。
进一步的，网络设备可以为其设置的各个传输接收点配置对应的扰码序列。例如，可以根据传输接收点的索引生成其对应的扰码序列。
其中，网络设备可以获取原始扰码序列，具体可以从一个golden序列(一种特性较好的伪随机序列)中确定一原始扰码序列SeqScrambGolden。
具体的，网络设备与终端设备可以约定从golden序列中确定原始扰码序列的方式，即终端设备也可以基于一定的规则确定出该原始扰码序列SeqScrambGolden。
进一步的，网络设备可以根据传输接收点的索引对原始扰码序列进行处理，得到与传输接收点对应的扰码序列。例如，网络设备上设置有多个传输接收点，那么可以根据各个传输接收点的索引确定出与传输接收点对应的扰码序列。
实际应用时，可以通过传输接收点的索引TrpScrambID指示应用于不同传输接收点上的PDSCH的扰码序列。在确定传输接收点的索引时，网络设备可以根据与一终端设备连接的传输接收点，确定这些传输接收点的索引。比如，若一个终端设备连接有M个传输接收点，则这M个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2、…、TrpScrambIDM。
一种可选的实施方式中，可以根据传输接收点的索引对原始扰码序列进行处理循环位移处理，进而得到与传输接收点对应的扰码序列。
具体的，加扰是数字信号的加工处理方法，就是用扰码序列与待发送给终端设备的信号相乘，从而得到加扰信号。与待发送给终端设备的信号相比，加扰信号在时间上、频率上被打散。
其中，网络设备向终端设备发送信号时，可以利用扰码序列对待发送给终端设备的信号进行加扰，再将加扰信号发送给该终端设备。具体可以由网络设备中设置的传输接收点向终端设备发送加扰信号，并根据发送信号的传输接收点对应的扰码序列对待发送的信号加扰。
例如，终端设备ue1连接有两个传输接收点，则这两个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2。网络设备可以利用TrpScrambID 1对原始扰码序列进行处理，得到第一扰码序列，利用TrpScrambID 2对原始扰码序列进行处理，得到第二扰码序列。当通过索引为TrpScrambID 1的传输接收点向ue1发送信号时，可以利用第一扰码序列对待发送信号加扰，得到加扰信号，再将加扰信号发送给ue1。当通过索引为TrpScrambID2的传输接收点向ue1发送信号时，可以利用第二扰码序列对待发送信号加扰，得到加扰信号，并将加扰信号发送给ue1。
步骤202，将所述加扰信号发送给所述终端设备。
具体的，网络设备可以利用其设置的传输接收点向终端设备发送加扰信号。终端设备接收到加扰信号之后，可以根据每个与其连接的传输接收点的扰码序列进行解扰，若利用一扰码序列对加扰信号解扰成功，则可以认为发送加扰信号的传输接收点是使用的扰码序列对应的传输接收点。
例如，终端设备可以利用其连接的传输接收点对应的索引对原始扰码序列进行处理，具体的处理方式可以与网络设备对原始扰码序列的处理方式相同。
进一步的，终端设备可以利用得到的扰码序列对接收的加扰信号进行解扰，若解扰成功，则说明该扰码序列对应的传输接收点是发送所述加扰信号的传输接收点。
实际应用时，终端设备可以根据已连接的传输接收点的索引，尝试对接收的加扰信号进行解扰，进而根据解扰结果识别出发送该加扰信号的传输接收点。
本实施例提供的方法用于对信号进行处理，该方法由设置有本实施例提供的方法的设备执行，该设备通常以硬件和/或软件的方式来实现。
本实施例提供的信号处理方法，应用于网络设备，方法包括：根据与传输接收点对应的扰码序列对待发送给终端设备的信号进行加扰，得到加扰信号，将所述加扰信号发送给所述终端设备。通过这种方式，当网络设备向终端设备发送加扰信号时，终端设备可以根据已连接的传输接收点的扰码序列对加扰信号进行解扰，进而识别出发送该加扰信号的传输接收点，从而能够响应该信号。
在一种可选的实施方式中，使用传输接收点的索引对原始扰码序列进行处理，得到与传输接收点对应的扰码序列。
其中，网络设备可以获取原始扰码序列，具体可以从一个golden序列(一种特性较好的伪随机序列)中确定一原始扰码序列SeqScrambGolden。
具体的，网络设备与终端设备可以约定从golden序列中确定原始扰码序列的方式，即终端设备也可以基于一定的规则确定出该原始扰码序列SeqScrambGolden。
进一步的，网络设备可以根据传输接收点的索引对原始扰码序列进行处 理，得到与传输接收点对应的扰码序列。例如，网络设备上设置有多个传输接收点，那么可以根据各个传输接收点的索引确定出与传输接收点对应的扰码序列。
实际应用时，可以通过传输接收点的索引TrpScrambID指示应用于不同传输接收点上的PDSCH的扰码序列。在确定传输接收点的索引时，网络设备可以根据与一终端设备连接的传输接收点，确定这些传输接收点的索引。比如，若一个终端设备连接有M个传输接收点，则这M个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2、…、TrpScrambID M。
其中，终端设备也可以基于上述方式确定与其连接的传输接收点的索引。
具体的，网络设备可以利用传输接收点索引中包括的数值m(m为1-M中的任一数值)对原始扰码序列进行处理。比如，针对索引为TrpScrambID 1的传输接收点，网络设备可以利用数值“1”对原始扰码序列进行处理，得到与索引为TrpScrambID 1的传输接收点对应的扰码序列。针对索引为TrpScrambID2的传输接收点，网络设备可以利用数值“2”对原始扰码序列进行处理，得到与索引为TrpScrambID 2的传输接收点对应的扰码序列。
进一步的，例如可以利用传输接收点索引中包括的数值对原始扰码序列进行循环位移，得到与传输接收点对应的扰码序列。再例如，还可以计算传输接收点索引中包括的数值与一预设数值N的乘积，再利用该乘积对原始扰码序列进行循环位移，得到与传输接收点对应的扰码序列。
可以将上面提到的传输接收点索引中包括的数值，或者乘积作为对原始扰码序列进行循环位移的位移位数。
实际应用时，循环方向可以是循环右移，也就是将移出的低位放到该数的高位；循环方向还可以循环左移，就是把移出的高位放到该数的低位。比如，针对序列1234，循环右移1位得到的序列为4123，循环左移1位得到的序列为2341。
在一种可选的实施方式中，所述索引用于指示位移位数，所述扰码序列为循环位移了位移位数的原始扰码序列。
其中，传输接收点的索引可以用于指示一位移位数。
一种方式中，传输接收点的索引中可以具有数值，可以将该数值直接作 为位移位数。比如，传输接收点的索引是TrpScrambID1，则位移位数是1。
再一种方式中，可以预先设定传输接收点索引与数值的对应关系，可以根据传输接收点的索引进行查表，从而确定对应的数值，位移位数可以是传输接收点索引对应的数值。可选的，该对应关系可以同步给终端设备，以使终端设备能够根据已连接的传输接收点的索引确定对应的数值。例如，传输接收点索引为A时，对应的数值可以为1。
其中，对原始扰码序列进行处理时，可以使用传输接收点的索引指示的位移位数对原始扰码序列进行循环位移，进而得到与传输接收点对应的扰码序列。即，传输接收点对应的扰码序列为循环位移了该传输接收点的索引指示的位移位数的原始扰码序列。例如，若一传输接收点索引指示的位移位数是m，则对原始扰码序列循环位移m位，得到与该传输接收点对应的扰码序列。
当终端设备根据传输接收点的索引对加扰信号进行解扰时，也可以使用上述位移位数对原始扰码序列进行循环位移，进而得到与该传输接收点对应的扰码序列。
在一种可选的实施方式中，所述索引具有对应的数值，位移位数为数值与预设数值之间的乘积。
其中，传输接收点的索引中可以具有数值，比如，传输接收点的索引是TrpScrambID1，则索引中具有的数值是1。还可以预先设置一预设数值N，N为一正整数。位移位数可以是传输接收点的索引具有对应的数值与预设数值的乘积。
具体的，若传输接收点的索引中具有的数值为m，预设数值为N，则位移位数等于m与N之间的乘积。网络设备对原始扰码序列进行处理时，可以使用该乘积对原始扰码序列进行循环位移，进而得到与该传输接收点对应的扰码序列。即，扰码序列为循环位移了m与N之间的乘积的原始扰码序列。
当终端设备根据传输接收点的索引对加扰信号进行解扰时，也可以使用上述乘积对原始扰码序列进行循环位移，进而得到与该传输接收点对应的扰码序列。
在一种可选的实施方式中，所述对应的数值小于或等于与所述终端设备连接的传输接收点的总个数。
进一步的，若一终端设备连接有M个传输接收点，则这些传输接收点的索引具有的数值小于或等于M。比如，传输接收点的索引中具有的数值可以是1-M之间的数值(包括1和M)。
实际应用时，网络设备能够获知与一终端设备连接的传输接收点，终端设备也能够获知自身连接的传输接收点。网络设备可以为各个传输接收点生成索引，比如依次可以是TrpScrambID1、TrpScrambID2…TrpScrambIDM。比如，可以根据终端设备接入传输接收点的顺序依次命名。可选的，终端设备也可以基于同样的方式生成已连接的传输接收点的索引。
其中，可以利用数值依次为与一个终端设备连接的传输接收点命名，使得传输接收点的索引具有对应的数值小于或等于与终端设备连接的传输接收点的总个数。
在一种可选的实施方式中，循环位移的方向为原始扰码序列的高位或低位。
其中，生成传输接收点对应的扰码序列时，可以对原始扰码序列进行循环位移，具体的循环位移的方向可以是原始扰码序列的高位方向，即从低位向高位位移。循环位移的方向也可以是原始扰码序列的低位方向，即从高位向低位位移。
网络设备生成传输接收点对应的扰码序列时可以采用上述方式，终端设备也可以基于上述方式生成传输接收点对应的扰码序列。
具体的，位移位数可以基于上述任一种方式确定。
在一种可选的实施方式中，网络设备中可以包括无线资源控制层(RRC)。可以通过无线资源控制层配置传输接收点的索引。例如，网络设备中设置有多个传输接收点，则可以由无线资源控制层配置这些传输接收点的索引。
在一种可选的实施方式中，网络设备中可以包括媒体访问控制层(MAC)。可以通过媒体访问控制层配置传输接收点的索引。例如，网络设备中设置有多个传输接收点，则可以由媒体访问控制层配置这些传输接收点的索引。
在一种可选的实施方式中，网络设备中可以包括物理层。可以通过物理 层配置传输接收点的索引。例如，网络设备中设置有多个传输接收点，则可以由物理层配置这些传输接收点的索引。
图3为本申请二示例性实施例示出的信号处理方法的流程图。
本申请提供的方法可以应用在终端设备中，例如图1中所示出的终端设备11。
如图3所示，本申请提供的方法可以包括：
步骤301，接收传输接收点发送的加扰信号，其中，所述加扰信号为依据所述传输接收点对应的扰码序列对待发送的信号进行加扰得到的。
其中，传输接收点在向终端设备发送信号时，可以利用所述传输接收点对应的扰码序列对待发送的信号进行加扰，得到加扰信号，再将加扰信号发送给终端设备，以使终端设备能够接收该加扰信号。
可选的，各个传输接收点可以具有对应的扰码序列，该扰码序列可以是网络设备为传输接收点确定的。
其中，可以依据传输接收点的索引对原始扰码序列进行处理所得到与传输接收点对应的扰码序列。
进一步的，在对原始扰码序列进行处理时，可以预先获取原始扰码序列，具体可以从一个golden序列(一种特性较好的伪随机序列)中确定一原始扰码序列SeqScrambGolden。
具体的，可以预先与终端设备约定从golden序列中确定原始扰码序列的方式，即终端设备也可以基于一定的规则确定出该原始扰码序列SeqScrambGolden。
进一步的，可以根据传输接收点的索引对原始扰码序列进行处理，得到与该传输接收点对应的扰码序列。例如，网络设备设置有多个传输接收点时，那么可以根据各个传输接收点的索引确定出与传输接收点对应的扰码序列。
在网络设备向终端设备发送信号时，具体可以利用其设置的传输接收点向终端设备发送信号。该传输接收点可以利用其对应的扰码序列对待发送给终端设备的信号进行加扰。
在确定传输接收点的索引时，可以根据与一终端设备连接的传输接收点，确定这些传输接收点的索引。比如，若一个终端设备连接有M个传输接收点， 则这M个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2…TrpScrambIDM。
假设终端设备ue1连接有两个传输接收点，则这两个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2。网络设备可以利用TrpScrambID 1对原始扰码序列进行处理，得到第一扰码序列，利用TrpScrambID 2对原始扰码序列进行处理，得到第二扰码序列。当通过索引为TrpScrambID 1的传输接收点向ue1发送信号时，可以利用第一扰码序列对待发送信号加扰，得到加扰信号，再将加扰信号发送给ue1。当通过索引为TrpScrambID2的传输接收点向ue1发送信号时，可以利用第二扰码序列对待发送信号加扰，得到加扰信号，并将加扰信号发送给ue1。
步骤302，获取至少一扰码序列并对所述加扰信号进行解扰，其中，所述扰码序列与所述传输接收点对应。
其中，每一传输接收点可以有其对应的扰码序列，本步骤中所述的至少一扰码序列可以是所述终端设备连接的传输接收点中的至少一个传输接收点对应的扰码序列。
具体的，终端设备接收到加扰信号之后，可以根据每个与其连接的传输接收点对应的扰码序列对加扰信号进行解扰。该扰码序列例如可以是终端设备对原始扰码序列进行处理得到的与各个传输节点对应的扰码序列，具体的处理方式可以与网络设备对原始扰码序列的处理方式相同。
进一步的，终端设备可以与网络侧约定获取原始扰码序列的方式，从而使终端设备与网络设备获取的原始扰码序列相同。比如，均为基于一定规则从一个golden序列中确定一原始扰码序列SeqScrambGolden。
实际应用时，终端设备还可以与网络侧确定生成与传输接收点对应的扰码序列的方式，比如可以利用传输接收点的索引对原始扰码序列进行处理，得到与该传输接收点对应的扰码序列。
其中，确定传输接收点索引的方式可以是利用数字依次对当前连接的传输接收点命名，比如一个终端设备连接有M个传输接收点，则这M个传输接收点的索引可以分别为TrpScrambID 1、TrpScrambID 2…TrpScrambIDM。
另一种方式中，还可以由网络侧为终端设备配置传输接收点的索引。可选的，可以通过以下任一种方式配置所述传输接收点的索引：通过无线资源 控制层(RRC)配置、通过媒体访问控制层(MAC)配置、通过物理层配置，用以快速动态地对各传输接收点的索引进行调整。终端设备可以获取通过所述无线资源控制层或所述媒体访问控制层或所述物理层配置的索引。

步骤303，根据解扰结果确定发送所述加扰信号的传输接收点。
若基于一已连接的传输接收点对加扰信号解扰成功，则可以将该传输接收点作为发送加扰信号的传输接收点。
可选的，若解扰后的信号校验成功，则该扰码序列对应的传输接收点为发送所述加扰信号的传输接收点。
具体来说，若通过一传输接收点对应的扰码序列对解扰后的信号进行校验时校验成功，则可以认为解扰成功，此时可以确定该传输接收点为发送所述加扰信号的传输接收点。若对解扰后的信号进行校验时校验失败，则可以认为解扰失败，那么该传输接收点不是发送所述加扰信号的传输接收点。实际应用时，加扰信号或解扰得到的信号中可以包括CRC校验码(Cyclic Redundancy Check，循环冗余校验)。终端设备可以根据解扰后的信号以及该CRC校验码进行校验处理，若校验通过，则可以认为解扰成功。
通过这样的方式，终端设备能够识别出发送加扰信号的传输接收点。
可选的，终端设备识别出发送加扰信号的传输接收点后，可以向该传输接收点发送响应信号，以响应接收的加扰信号。具体的响应信号可以根据解扰成功的解扰信号确定。
