下面参考附图对本公开实施例所提供的预编码测量方法/装置/设备及存储介质进行详细描述。
图1为本公开实施例所提供的一种预编码方法的流程示意图，其中，本公开实施例提供的方法可以应用至多UE场景，该方法由辅助通信设备执行，如图1所示，该预编码方法可以包括以下步骤：
步骤101、获取网络侧设备发送的预编码信息。
其中，在本公开的一个实施例之中，上述辅助通信设备可以为智能中继器(Smart Repeater)和/或RIS阵列。
其中，在本公开的一个实施例之中，该预编码信息可以包括以下至少一种：
至少一个特定PMI(Precoding Matrix Index，预编码矩阵索引)；
每个特定PMI对应的加权系数集；其中，加权系数集包括至少一个加权系数，每个特定PMI对应的加权系数集由每个特定PMI与至少一个UE对应的加权系数确定。
需要说明的是，在本公开的一个实施例之中，上述的预编码信息可以是网络侧设备基于来自至少两个UE的PMI信息确定的。即，所述预编码信息可以是网络侧设备根据至少两个UE的PMI信息确定的。其中，在本公开的一个实施例之中，该PMI信息可以包括多个PMI信息，其中这多个PMI信息可以对应于两个或两个以上UE；其中一个UE可以对应一个或多个PMI信息。在本公开实施中，所述至少两个UE的PMI信息包括：至少两个UE发送的PMI。进一步的，该至少两个UE的PMI信息还可以包括：每个PMI与至少两个UE中的每一个UE对应的加权系数。其中，所述PMI包括UE对应的信道质量最好的M个PMI和/或最坏的N个PMI，其中，M、N为大于等于0的整数。以及，该PMI对应的加权系数与利用该PMI对入射波束进行预编码得到的复合波束与UE的偏向程度呈正相关。例如，示例性的，预编码码本包含N个预编码矩阵，UE计算出的最佳预编码矩阵W，使用码本中的X个预编码矩阵的线性组合对最优预编码矩阵进行逼近，加权系数即为线性组合的加权系数。在一个可能的示例中，假设有10个候选预编码矩阵(X＝10)，UE计算出来的最佳波束预编码矩阵并不在候选预编码矩阵之中，因此可以用10个候选预编码矩阵中的所有或部分(比较靠近最佳波束预编码矩阵的几个候选预编码矩阵)进行逼近，从而确定候选预编码矩阵的加权系数；即，越逼近最佳波束预编码矩阵的候选预编码矩阵，其加权系数越高。
以及，在本公开的一个实施例之中，上述的PMI信息可以是UE直接发送至网络侧设备，在本公开的另一个实施例之中，上述的PMI信息可以是UE通过辅助通信设备转发至网络侧设备的，即：UE先将该PMI信息发送至辅助通信设备，再由辅助通信设备将PMI信息转发至网络侧设备。在本公开实施例中，辅助通信设备示例性的可以为Smart Repeater(智能中继器)/RIS。
此外，在本公开的一个实施例之中，UE在发送PMI信息中的PMI时，可以是按照特定顺序来依次发送该PMI的。其中，在本公开的一个实施例之中，该特定顺序可以为：按照PMI索引从小到大的顺序，在本公开的另一个实施例之中，该特定顺序可以为：按照PMI对应信道质量从最好到最坏的顺序，在本公开的又一个实施例之中，该特定顺序可以为：按照PMI对应信道质量从最坏到最好的顺序。当然，UE在发送PMI信息中可以包括一个或多个PMI；若只发送一个PMI，则无需进行排序；若发送多个PMI，则可以按照上述方式或是任何可能的方式进行排序。
示例的，在本公开的一个实施例之中，假设某UE向网络侧设备发送的PMI信息中包括两个PMI，分别为该UE对应的信道质量最坏的PMI-1、以及信道质量最好的PMI-2。此时，该UE发送该两个PMI的顺序可以为按照PMI索引的由小到大的顺序发送，即：依次发送PMI-1、PMI-2；或者，该UE发送该两个PMI的顺序可以为按照PMI对应信道质量从最好到最坏的顺序，即：依次发送PMI-2、PMI-1；或者，该UE发送该两个PMI的顺序可以为按照PMI对应信道质量从最坏到最好的顺序，即：依次发 送PMI-1、PMI-2。
还需要说明的是，在本公开的一个实施例之中，上述的PMI与UE对应的加权系数是一可选选项，即，UE可以向网络侧设备发送该UE所发送的每个PMI以及该UE的每个PMI与UE对应的加权系数，也可以不向网络侧设备发送该UE的每个PMI与UE对应的加权系数，而仅发送PMI即可。如前所述的，该UE的每个PMI与UE对应的加权系数，PMI对应的加权系数与利用该PMI对入射波束进行预编码得到的复合波束偏向于该PMI对应的UE的程度呈正相关。
在本公开的一个实施例之中，所述预编码信息可以是网络侧设备根据接收到的各个UE发送的PMI信息对应的所有PMI中选择至少一个特定PMI，并基于至少一个特定PMI对应的加权系数确定每个特定PMI的加权系数集；之后，将至少一个特定PMI和/或每个特定PMI对应的加权系数集确定为预编码信息。其中，该加权系数集包括至少一个加权系数，每个特定PMI对应的加权系数集由每个特定PMI与至少一个UE对应的加权系数确定。在本公开实施例中，针对每一个PMI，不同的UE对应不同的加权系数；可以根据其中全部或部分UE对应的加权系数，生成该PMI所对应的加权系数集。
需要说明的是，在本公开的一个实施例之中，在选择特定PMI时，主要是基于该辅助通信设备对应的目标UE确定的，其中，该目标UE即为要接收该辅助通信设备反射和/或透射入射波束后得到的复合波束的UE。以及，所选择的特定PMI应当满足以下条件：利用该特定PMI对入射波束进行预编码得到复合波束后，该复合波束能够被该目标UE准确接收。
基于此，该特定PMI可以包括以下至少一种：
目标UE对应的信道质量最好的至少一个PMI；
非目标UE对应的信道质量最差的至少一个PMI。
以及，需要说明的是，在本公开的一个实施例之中，当确定了特定PMI之后，可以直接将特定PMI对应的所有UE的加权系数，确定为特定PMI的加权系数集。在本公开的另一个实施例之中，当确定了特定PMI之后，网络侧设备还可以对该特定PMI对应的加权系数进行更改，并将更改之后的加权系数确定为特定PMI的加权系数集。
示例的，在本公开的一个实施例之中，假设当前具备有两个UE，分别为UE-1、UE-2，其中，UE-1发送至基站的PMI信息为：质量最好的PMI-1、PMI-1对应的加权系数a、质量最坏的PMI-2、以及PMI-2对应的加权系数b；UE-2发送至基站的PMI信息为：质量最坏的PMI-3、质量最好的PMI-4、PMI-3对应的加权系数c、PMI-4对应的加权系数d。其中，目标UE为UE-1，则网络侧设备可以将PMI-1、PMI-3确定为特定PMI，以及，可以将加权系数a确定为特定PMI-1的加权系数集、将加权系数c确定为特定PMI-3的加权系数集。
则通过执行上述步骤，网络侧设备即可确定出预编码信息，之后，可以将预编码信息发送至辅助通信设备。
需要说明的是，在本公开的一个实施例之中，网络侧设备在向辅助通信设备发送预编码信息时，可以可选性地向辅助通信设备发送一个特定PMI对应的加权系数集或部分特定PMI对应的加权系数集；即，网络侧设备可以向辅助通信设备发送每个特定PMI对应的加权系数集，也可以不向辅助通信设备发送每个特定PMI对应的加权系数集，而仅发送一个特定PMI或是几个特定PMI即可。
步骤102、基于预编码信息对入射波束进行预编码以形成复合波束，并发射复合波束。
其中，在本公开的一个实施例之中，辅助通信设备基于预编码信息对入射波束进行预编码时具体可以是：基于特定PMI和/或特定PMI对应的加权系数集确定复合波束。在一种可能的实现方式中，可以基于特定PMI和/或特定PMI对应的加权系数集，按照特定方向反射和/或透射入射波束，得到复合波束。
进一步的，该方法中还可以包括：向UE发射该复合波束。具体的，该网络设备可以向一个UE发射该复合波束，也可以向多个UE设备发射该复合波束。
综上所述，在本公开实施例提供的预编码方法之中，辅助通信设备会获取网络侧设备发送的预编码信息，之后，会基于预编码信息对入射波束进行预编码以形成复合波束，并发射复合波束。由此，在本公开实施例中，辅助通信设备是基于网络侧设备发送的预编码信息对入射波束进行预编码的，则复杂性 较低，适用性较高。

以及，在本公开的一个实施例之中，上述的PMI信息可以是UE直接发送至网络侧设备，在本公开的另一个实施例之中，上述的PMI信息可以是UE通过辅助通信设备转发至网络侧设备的，即：UE先将该PMI信息发送至辅助通信设备，再由辅助通信设备将PMI信息转发至网络侧设备。在本公开实施例中，辅助通信设备示例性的可以为Smart Repeater(智能中继器)/RIS。
此外，在本公开的一个实施例之中，UE在发送PMI信息中的PMI时，可以是按照特定顺序来依次发送该PMI的。其中，在本公开的一个实施例之中，该特定顺序可以为：按照PMI索引从小到大的顺序，在本公开的另一个实施例之中，该特定顺序可以为：按照PMI对应信道质量从最好到最坏的顺 序，在本公开的又一个实施例之中，该特定顺序可以为：按照PMI对应信道质量从最坏到最好的顺序。当然，UE在发送PMI信息中可以包括一个或多个PMI；若只发送一个PMI，则无需进行排序；若发送多个PMI，则可以按照上述方式或是任何可能的方式进行排序。具体可以参见前述实施例中的示例。

步骤b、网络侧设备基于各个UE的PMI信息确定上述预编码信息。
在本公开的一个实施例之中，所述预编码信息可以是网络侧设备根据接收到的各个UE发送的PMI信息对应的所有PMI中选择至少一个特定PMI，并基于至少一个特定PMI对应的加权系数确定每个特定PMI的加权系数集；之后，将至少一个特定PMI和/或每个特定PMI对应的加权系数集确定为预编码信息。其中，该加权系数集包括至少一个加权系数，每个特定PMI对应的加权系数集由每个特定PMI与至少一个UE对应的加权系数确定。在本公开实施例中，针对每一个PMI，不同的UE对应不同的加权系数；可以根据其中全部或部分UE对应的加权系数，生成该PMI所对应的加权系数集。
在本公开的一个实施例之中，在选择特定PMI时，主要是基于该辅助通信设备对应的目标UE确定的，其中，该目标UE即为要接收该辅助通信设备反射和/或透射入射波束后得到的复合波束的UE。以及，所选择的特定PMI应当满足以下条件：利用该特定PMI对入射波束进行预编码得到复合波束后，该复合波束能够被该目标UE准确接收。
