本申请主张在2022年03月02日在中国提交的中国专利申请No.202210197639.8的优先权，其全部内容通过引用包含于此。
技术领域
本申请涉及无线通信技术领域，尤其涉及一种非正交多址检测方法、装置及相关设备。
背景技术
未来第六代移动通信技术(6th generation mobile networks，6G)系统对用户体验速率、系统容量、连接数以及时延指标都提出了更高要求，相关技术中的正交多址(Orthogonal Multiple Access，OMA)技术可能无法满足6G要求，为此我们引入了非正交多址(Non-Orthogonal Multiple Access，NOMA)技术，NOMA技术相比于传统的OMA技术，具有以下优点，一是通过多用户信息的叠加传输，在相同的时频资源上可以支持更多的用户连接，可有效满足未来海量设备连接能力指标要求；二是利于实现免调度传输，相比于OMA技术可有效简化信令流程，降低空口时延；三是利用多维调制以及码域扩展可获得更高的频谱效率。
NOMA技术中一个子信道上不再只分配给一个用户，而是多个用户共享，即将多个用户的数据在一个子信道上传输，那么网络侧设备接收到多个用户的数据后，如何对利用NOMA技术的进行传输的数据进行检测成为亟待解决的问题。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。在本申请中的实施例的基础上，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，都属于本申请保护的范围。
请参见图1，图1是本申请实施例可应用的网络系统的结构图，如图1所示，包括终端11和网络侧设备12。终端11和网络侧设备12之间可进行通信。
终端11也可以称作用户设备(User Equipment，UE)、用户终端，在实际应用中，终端可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等。网络侧设备12可以是基站、接入点或其他网元等。
以下对本申请实施例提供的非正交多址检测方法进行说明。
参见图2，图2是本申请实施例提供的非正交多址检测方法的流程示意图。图2所示的非正交多址检测方法可以由网络侧设备执行。
如图2所示，非正交多址检测方法可以包括以下步骤：
步骤201，获取目标码本，所述目标码本包括V个子码本，所述子码本 用于承载用户发送的数据，V为正整数；
上述目标码本为根据非正交多址接入(Non-Orthogonal Multiple Access,NOMA)系统确定的码本。非正交多址技术主要基于用户发送的数据在物理资源上的叠加传输来实现，在接收端采用基于串行干扰删除(Successive Interference Cancellation，SIC)技术或迭代消息传递的算法实现多用户检测。
具体实现时，可采用叠加矩阵或因子图的形式对目标码本进行描述。示例性地，对于3用户2资源的图样分割多址接入(Pattern division multiple access，PDMA)系统，PDMA系统是NOMA系统中的一种，其叠加矩阵F表示为
矩阵F的每一列对应一个子码本，用于承载用户发送的数据。矩阵F的三列分别对应三个子码本，每一个子码本可以分配给一个用户终端使用。矩阵中的数字代表资源占用情况，1表示占用该资源，0表示不占用该资源，矩阵F的第一列对应的子码本占用两个资源，矩阵F的第二列占用第一个资源，矩阵F的第三列占用第二个资源。
网络侧设备将目标码本中的子码本分配给用户终端使用，用户终端基于分配得到的子码本对其发送的数据进行编码，编码方案可以采用极化(Polar)码方案。Polar码可以达到香农极限且具有可实用化的线性复杂度编译码能力，且Polar码被业界确定为5G eMBB场景的控制信道编码方案。具体实现时，参见图3，图3是本申请实施例提供的上行Polar极化码-NOMA系统的结构示意图，对于用户v，其输入到Polar编码器G的数据块中包含Kv比特，经过编码得到长度N比特的码字，码率Rv＝Kv/N。经过交织器后，码字中的每J个比特形成向量：
其中，J为调制阶数，τ＝1,2,...,N/J为个交织器中数据帧的时隙序号。接着每个向量bv将通过信号映射成一个F维的NOMA码字xv＝(xv,1,xv,2,...,xv,F)。映射函数可以表示为：gv:BJ→Xv，其中表示用户v的码本且|Xv|＝M，J＝log2(M)。由全部V个用户的码本组成集合{Xv}，基站为每个用户分配一个不同的码本。对于NOMA系统，V>F，定义系统过载率为J＝V/F。对于 Polar-NOMA系统，NOMA信道在三级信道极化变换下可以被分解为一系列比特极化信道。
具体实现时，参见图4，图4是本申请实施例提供的传输竞争单元的结构示意图。为了支持上行免授权接入，还可以定义传输竞争单元(Contention Transmission Unit，CTU)对目标码本进行描述。示例性地，定义了传输竞争单元(Contention Transmission Unit，CTU)，表示为频率、时间、码本、导频序列的组合{f,t,Cj,Pj}。其中，每块时频资源有V个不同的码本，每个码本对应M个导频，总共有VM个不同的导频序列，即每个时频块有VM个CTU。应理解，导频位于资源上，有多少个导频就有多少个资源。每列时频块代表一个子码本。
步骤202，根据所述目标码本，确定与所述V个子码本对应的V组信道质量指示信息；
V组信道质量指示信息可包括用于描述V个子码本的传输性能的信息，传输性能可用传输容量表征。可选地，所述信道质量指示信息包括信干噪比和瞬时速率中的至少一项。但应理解，信道质量指示信息并不仅限于信干噪比，和/或瞬时速率。每个子码本对应的信道质量指示信息不同，具体而言，子码本的信道质量指示信息跟子码本的资源使用情况有关，可以通过子码本的资源使用情况确定子码本的信道质量指示信息。
可选地，所述步骤202，包括：
根据所述目标码本，确定所述V个子码本的V个资源使用信息。
具体实现时，可以根据描述目标码本的矩阵F确定V个子码本的资源使用信息。资源使用信息包括度df即矩阵F中第f行中的1的个数，表示矩阵F中第f行中的资源使用情况，以表达式(1)为例，d1＝2，即矩阵F的第一行使用了两个资源。资源使用信息还包括矩阵F中第v列非0行的集合FV，仍以表达式(1)为例，F1包括{1}、{2}、{1、2}，{1}表示第一行非0，{2}表示第二行非0，{1、2}表示第一行和第二行非0。
根据所述V个资源使用信息、预先获取的信号发射功率和预先获取的噪声功率，确定与所述V个子码本对应的V个所述信干噪比，和/或与所述V个子码本对应的V个所述瞬时速率。
具体实现时，可以根据上述矩阵F和如下表达式依次确定与V个子码本对应的V个信干噪比
其中，Dk＝{s1,s2,...,sk}表示已经完成检测的用户序号集合，常数l＝P/N0，P为用户终端的信号发射功率，N0为噪声功率，df为度即矩阵F中第f行中的1的个数，f代表矩阵F的行数，f的取值范围为1至M中的正整数，M为正整数，M代表矩阵F中的资源数。FV代表矩阵F中第v列非0行的集合。
瞬时速率与信干噪比正相关，具体的，瞬时速率等于在具体实现时，可以确定与V个子码本对应的V个信干噪比，和/或与V个子码本对应的V个瞬时速率。
步骤203，对所述V组信道质量指示信息进行排序，获得目标检测顺序；
具体实现时，在V组信道质量指示信息包括V个信干噪比的情况下，可以将V个信干噪比按升序或者降序排列，得到信干噪比的排列顺序，前文已述信干噪比与子码本一一对应，因此可以根据信干噪比的排列顺序，确定与该排列顺序对应的子码本的排列顺序。又由于各子码本分配给不同的用户终端使用，即子码本与用户终端一一对应，可将子码本的排列顺序确定为目标检测顺序。
在V组信道质量指示信息包括V个瞬时速率的情况下，可以将V个瞬时速率按升序或者降序排列，得到瞬时速率的排列顺序，前文已述瞬时速率与子码本一一对应，因此可以根据瞬时速率的排列顺序，确定与该排列顺序对应的子码本的排列顺序。又由于各子码本分配给不同的用户终端使用，即子码本与用户终端一一对应，可将子码本的排列顺序确定为目标检测顺序。
在V组信道质量指示信息包括V个信干噪比和V个瞬时速率的情况下，因为信干噪比与瞬时速率正相关，因此可以任意选择将V个信干噪比按升序或者降序排列，或将V个瞬时速率按升序或者降序排列，两种方式下最终确定的与该排列顺序对应的子码本的排列顺序相同。又由于各子码本分配给不 同的用户终端使用，即子码本与用户终端一一对应，可将子码本的排列顺序确定为目标检测顺序。
步骤204，根据所述目标检测顺序，对所述V个子码本承载的数据进行检测。
本申请采用NOMA技术对用户数据进行传输，在用户终端发送时，对同一子信道上的不同用户基于上述目标码本进行数据发送，每个子码本对应的信道质量指示信息不同。因此，将不同的子码本分配给不同的用户的情况下，到达网络侧设备的每个用户数据的信干噪比和瞬时速率都不同。
网络侧设备每一次只检测一个用户的数据，若有V个用户，则需要V次检测。对V个用户发送的数据进行检测的顺序为目标检测顺序。具体而言，可以按信噪干比越大则越先检测的原则确定目标检测顺序，这样的话，用户终端分配到的子码本的信干噪比越大，该用户终端所发送给网络侧设备的数据越先被检测。每次检测后去除该次检测的用户数据，并将去除该次检测的用户数据之后所得到的用户数据作为下一次检测的依据。
本申请实施例中，由于子码本分别分配给不同的用户使用，每个子码本的信道质量指示信息不同，通过确定与V个子码本对应的V组信道质量指示信息，则可将在一个子信道上传输的多个用户数据区分开来，再对V组信道质量指示信息进行排序，获得目标检测顺序，这样，可以根据目标检测顺序，对接收的用户数据即V个子码本承载的数据进行检测，从而解决了如何对利用NOMA技术的进行传输的数据进行检测的问题。
需要说明的是，网络侧设备接收到的是用户终端基于分配得到的子码本对其发送的数据进行编码后的数据，本申请实施例可根据目标检测顺序，对V个子码本承载的数据进行检测，并恢复出用户发送的编码前的数据。
可选地，所述步骤203，包括：
根据V个所述信干噪比的第一顺序，对所述V组信道质量指示信息进行排序，获得第一序列；根据所述第一序列中信道质量指示信息的顺序，确定所述V个子码本的排列顺序；将所述V个子码本的排列顺序，确定为所述目标检测顺序，其中，所述V个子码本的排列顺序与所述第一序列中信道质量指示信息的顺序相同。
具体实现时，在V组信道质量指示信息包括V个信干噪比的情况下，可以根据信干噪比确定子码本的排列顺序，第一顺序可以为升序或者降序。按照V个信干噪比的排列顺序与V组信道质量指示信息的排列顺序相同的原则，确定第一序列。
或者，根据V个所述瞬时速率的第二顺序，对所述V组信道质量指示信息进行排序，获得第二序列；根据所述第二序列中信道质量指示信息的顺序，确定所述V个子码本的排列顺序；将所述V个子码本的排列顺序，确定为所述目标检测顺序，其中，所述V个子码本的排列顺序与所述第二序列中信道质量指示信息的顺序相同。
具体实现时，在V组信道质量指示信息包括V个瞬时速率的情况下，可以根据瞬时速率确定子码本的排列顺序，第二顺序可以为升序或者降序。按照V个瞬时速率的排列顺序与V组信道质量指示信息的排列顺序相同的原则，确定第二序列。
可选地，所述步骤201之后，所述方法还包括：
确定与所述V个子码本对应的V个调制与编码策略MCS等级。各子码本所支持的MCS等级不同，可以根据目标码本中的资源使用情况确定各子码本的MCS等级
根据用户需求和所述V个MCS等级，将所述V个子码本分配给用户终端。
具体实现时，可以根据用户终端的实际需求，将各子码本分配给不同的用户使用，示例性地，用户终端A对MSC等级的要求较高，用户终端B对MSC等级的要求较低，则将目标码本中MCS等级较高的子码本分配给用户终端A使用，将目标码本中MCS等级较低的子码本分配给用户终端B使用。这样，根据用户需求和V个MCS等级，将V个子码本分配给用户终端，可以合理调度资源，从而实现对资源较高效率的利用。
前文已述，各子码本的资源使用信息不同，若给不同的用户终端分配不同的子码本，则会使各用户终端的吞吐率不同，这样则会失去对用户终端分配子码本的公平性。为保证公平性，使各用户终端的吞吐率基本一致，本申请实施例基于轮训调度(Round-Robin Schedule，RRS)的思想，为各个用户 公平的分配资源，可选地，所述步骤201之后，所述方法还包括：
获取用户终端的初始子码本序号和移位步长，所述初始子码本序号为所述V个子码本的任意一个子码本的子码本序号，所述移位步长小于V。
根据所述初始子码本序号和所述移位步长，确定所述用户终端当前轮次的各目标子码本序号；
将所述各目标子码本序号对应的子码本分配给所述用户终端使用。
具体实现时，以目标码本被表示为矩阵F为例，矩阵F的第一列代表第一个子码本，其子码本序号为1，矩阵F的第二列代表第二个子码本，其子码本序号为2…矩阵F的第V列代表第V个子码本，其子码本序号为V。若有V个用户终端，则应为V个用户终端中的各用户终端均分配一个初始子码本序号和移位步长，初始子码本序号为1至V中任一个正整数。因一个子码本一次只能给一个用户终端使用，所以各用户终端分配到的初始子码本序号不同。
初始轮次即第0轮次中，各用户终端分配得到的子码本为与初始子码本序号对应的子码本，第Q轮次中(Q为正整数)，各用户终端分配得到的子码本为与目标序号对应的子码本，目标序号等于移位步长与Q的乘积值与初始子码本序号之和。
作为一个示例，以半静态配置为例，网络侧设备可以利用下行链路控制信息((Downlink Control Information，DCI)信令添加seq_init(初始子码本序号)和step_cycle(移位步长)字段为用户终端配置码本序号。seq_init字段占用step_cycle字段占用对于用户k，在发送第一个码块时按照init_seq指定的码本序号及对应码率进行Polar编码，第二次发送时将按照step_cycle的值对初始序号进行移位，得到新的码本序号直至发送完成。seq_init的取值及对应的码本排序(Codebook sequence)可如表1所示：

表1
本申请实施例中，通过获取用户终端的初始子码本序号和移位步长，根据初始子码本序号和移位步长，确定用户终端当前轮次的各目标子码本序号，将各目标子码本序号对应的子码本分配给用户终端使用。可以实现将目标码本中的各子码本轮流分配给各用户终端使用，从而使用户终端可以共享到整套码本。具体而言，若在预设时间段内，可以实现两个轮次的子码本分配，那么根据初始子码本序号和移位步长，若用户终端A在第一轮次中分配到序号为1的子码本，用户终端B在第一轮次中分配到序号为2的子码本，那么在第二轮次中，用户终端A可能分配到序号为2的子码本，用户终端B可能分配到序号为1的子码本，这样，在该预设时间段内，用户终端A两次分配到的吞吐率之和与用户终端B两次分配到的吞吐率之和是相同的，从而使各用户终端的吞吐率基本一致，保证了对用户终端分配子码本的公平性。
