下面结合附图对本公开所提供的上行8端口码本的生成方法及其装置进行详细地介绍。
图2是本公开实施例提供的一种上行8端口码本的生成方法的流程示意图，该方法由网络侧设备执行。
如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：获取第一码字集合。
其中，第一码字集合，可以用于从中进行部分码字选择，以生成最终的码本的初始码字集合，该第一码字集合例如可以为R15版本通信协议的下行Type I码本，或者可以为选取采样值对R15版本通信协议的下行Type I码本进行降采样后得到的码本，或者上述两个码本的子集，对此不做限制。
本公开实施例中，在获取第一码字集合时，可以获取R15版本通信协议的下行Type I码本作为第一码字集合，或者选取适当的采样值，对R15版本通信协议的下行Type I码本进行降采样处理，将降采样处理后得到的码本作为第一码字集合，或者还可以选取对R15版本通信协议的下行Type I码本子集作为第一码字集合，以及选取对R15版本通信协议的下行Type I码本进行降采样处理后得到的码本的子集作为第一码字集合，对此不做限制。
步骤S202：根据第一码字集合生成第二码字集合。
其中，第二码字集合，是指从第一码字集合中选取的部分码字构成的码字集合，可以根据最优码字的概率分布选取第一码字集合中的码字以生成第二码字集合。
本公开实施例中，在根据第一码字集合生成第二码字集合时，可以根据上行信道状态信息(Channel State Information，CSI)统计不同层数的最优码字的概率分布，根据统计得到的最优码字的概率分布从第一码字集合中选取部分码字生成第二码字集合，举例而言，第一码字集合中共包含K 1个码字，则可以根据最优码字的概率分布第一码字集合中的K 1个码字中选取K 2个码字，将选取到的K 2个码字作为第二码字集合，或者可以采用其他任意可能的方式根据第一码字集合生成第二码字集合，对此不做限制。
本公开实施例在根据第一码字集合生成第二码字集合之后，可以根据第二码字集合生成上行8端口全相干传输码字集合，具体描述可见后续实施例。
步骤S203：根据第二码字集合生成上行8端口全相干传输码字集合。
本公开实施例在上述获取第一码字集合并根据第一码字集合生成第二码字集合之后，可以根据第二码字集合生成上行8端口全相干传输码字集合。
其中，上行8端口全相干传输码字集合，是指全相干传输场景下的码字集合，该上行8端口全相干传输码字集合可以从第二码字集合中选取码字生成。
举例而言，从第一码字集合中生成而来的第二码字集合共包含K 2个码字，则可以针对第二码字集合确定K 3个码字，以生成上行8端口全相干传输码字集合。
本公开实施例中，在根据第二码字集合生成上行8端口全相干传输码字集合时，可以确定一些参数，根据确定到的参数，以根据第二码字集合生成上行8端口全相干传输码字集合，该参数例如可以为波束和共相位系数等，可以选择根据波束从第二码字集合中选取码字以生成上行8端口全相干传输码字集合，或者选择根据共相位系数据从第二码字集合中选取码字以生成上行8端口全相干传输码字集合，亦或者联合波束与共相位系数，从第二码字集合中选取码字以生成上行8端口全相干传输码字集合，或者还可以采用其他任意可能的方式根据第二码字集合生成上行8端口全相干传输码字集合，对此不做限制。
步骤S204：根据上行8端口全相干传输码字集合生成终端设备的上行8端口码本。
其中，码本是一种赋形方式，可以根据码本对数据进行预编码，上行8端口码本可以支持将终端设备的端口数扩展为8时的数据传输。
本公开实施例在上述根据第二码字集合生成上行8端口全相干传输码字集合之后，可以根据上行8端口全相干传输码字集合生成终端设备的上行8端口码本。
本公开实施例中，在根据上行8端口全相干传输码字集合生成终端设备的上行8端口码本时，可以确定部分相干传输码本设计方案，根据部分相干传输码本设计方案与上行8端口全相干传输码字集合，确定对应的上行8端口部分相干传输码字集合，而后可以对终端设备的能力进行分析，如果终端设备支持非相干传输，则可以将对角矩阵作为上行8端口非相干传输码字集合，而后可以将上行8端口全相干传输码字集合、部分相干传输码字集合以及非相干传输码字合集作为R18版本通信协议下的上行8端口码本，如果终端设备不支持非相干传输，则可以将上行8端口全相干传输码字集合、部分相干传输码字集合作为R18版本通信协议下的上行8端口码本，以实现根据上行8端口全相干传输码字集合生成终端设备的上行8端口码本。
本实施例中，通过获取第一码字集合，根据第一码字集合生成第二码字集合，根据第二码字集合生成上行8端口全相干传输码字集合，根据上行8端口全相干传输码字集合生成终端设备的上行8端口码本，能够有效减少码本中的码字数量，从而减少根据上行8端口码本发送预编码矩阵指示的开销。

步骤S301：获取第一码字集合。
可选地，一些实施例中，第一码字集合，包括以下任意一个：R15下行Type I码本，降采样码本，其中，降采样码本为通过对R15下行Type I码本选取的采样值进行降采样所生成的码本，R15下行Type I码本的子集，降采样码本的子集。
本公开实施例中，在获取第一码字集合时，可以获取R15下行Type I码本、降采样码本、R15下行Type I码本的子集或者R15下行Type I码本的子集中的任意一个作为第一码字集合。
其中，降采样码本为通过对R15下行Type I码本选取的采样值进行降采样所生成的码本。
本公开实施例中，在选取采样值对R15下行Type I码本进行降采样处理以生成对应的降采样码本时，可以采用如下两种天线维度和过采样值，对R15下行Type I码本进行降采样处理，其中一种天线维度和过采样值为(N 1,N 2,O 1,O 2)＝(4,1,4,1)和(N 1,N 2,O 1,O 2)＝(2,2,4,4)，另一种天线维度和过采样值为(N 1,N 2,O 1,O 2)＝(4,1,2,1)和(N 1,N 2,O 1,O 2)＝(2,2,2,2)，可以分别针对这两种天线维度和过采样值对R15下行Type I码本进行降采样处理，以生成对应的降采样码本，例如(N 1,N 2,O 1,O 2)＝(4,1,2,1)时，第一码字集合中码字的数量为K 1＝32个。
步骤S302：获取不同层数的最优码字的概率分布。
其中，该不同层数的最优码字的概率分布可以为不同系统参数下一段时域资源内统计的概率分布。
本公开实施例中，在获取不同层数的最优码字的概率分布时，可以由网络侧设备通过探测参考信号(Sounding Reference Signal，SRS)进行信道估计，遍历码本中的码字，计算不同码字对应的信道容量，统计一段时频资源内各个码字被选为最优码字的概率分布，以实现获取不同层数的最优码字的概率分布。
另一些实施例中，可以由网络侧设备通过探测参考信号SRS进行信道估计，通过矩阵奇异值分解(Singular Value Decomposition，SVD)分解得到最优的码字，遍历码本中的码字，计算不同码字和最优码 字的距离，可用矩阵的F范数表示，统计一段时频资源内各个码字被选为最优码字的概率分布，以实现获取不同层数的最优码字的概率分布。
步骤S303：根据不同层数的最优码字的概率分布从第一码字集合之中的码字生成第二码字集合。
本公开实施例在上述获取不同层数的最优码字的概率分布之后，可以根据不同层数的最优码字的概率分布从第一码字集合之中的码字生成第二码字集合。
本公开实施例中，在根据不同层数的最优码字的概率分布从第一码字集合之中的码字生成第二码字集合时，可以设置一个概率阈值Pa，该概率阈值Pa例如可以设置为Pa＝0.01％，当概率分布中各个码字的概率大于Pa时，则将该码字选为第二码字集合，可以从第一码字集合K 1＝32个码字中，选取K 2＝16个码字作为第二码字集合，以实现根据不同层数的最优码字的概率分布从第一码字集合之中的码字生成第二码字集合。
举例而言，如图4所示，图4是本公开实施例中的CDL-C信道下的概率分布图，可调整参数获得多组概率分布，通过概率分布从第一码字集合之中确定第二码字集合，例如，下表1给出(N 1,N 2,O 1,O 2)＝(4,1,2,1)参数下不同系统条件选取出的码字集合，表2给出(N 1,N 2,O 1,O 2)＝(2,2,2,2)参数下不同系统条件选取出的码字集合。
