Description

资源映射方法及装置
本申请要求于2018年08月31日提交国家知识产权局、申请号为201811025065.6、发明名称为“资源映射方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种资源映射方法及装置。
背景技术
目前，移动通信技术已从第一代(1th-Generation，1G)移动通信技术发展至第四代(4th-Generation，4G)移动通信技术，第五代(5th-Generation，5G)移动通信技术也已经开始处于研究、标准化阶段。每一代移动通信技术均有其对应的物理层多址接入方式，其中，1G至4G的多址接入方式以正交多址接入为主，即不同终端占用不同的时间或者频率资源。在5G中，为了进一步提高系统容量和频谱效率，提出一种非正交多址接入(Non-Orthogonal Multiple Access，NOMA)技术，允许不同终端复用同一时频资源，并以不同终端在同一时频资源中的发射功率来区分终端。
可见，针对上述NOMA场景，需要确定终端收发数据时所使用的时频资源。现有技术中提供一种采用随机种子映射资源的方法，为不同终端配置不同的随机种子，不同随机种子生成不同随机序列，进而不同终端使用不同随机序列对应的时频资源来收发数据。
然而，上述采用随机种子映射资源的方法，需要网络设备为不同终端维护不同的随机种子，且在利用随机种子生成随机序列的过程中还需进行大量运算，使得映射资源的流程较为复杂。
发明内容
本申请提供一种资源映射方法及装置，以降低资源映射的复杂度。
为达到上述目的，本申请采用如下技术方案：
第一方面，本申请提供一种资源映射方法，该方法应用于接入网设备或者接入网设备的芯片，该方法包括：接入网设备获取至少一个终端的资源映射信息，并分别向至少一个终端发送各自的资源映射信息。其中，资源映射信息用于指示至少一个终端中每一终端在第一资源映射块RMB集合的每一RMB中所映射的资源单元RE，第一终端在第一RMB集合的每一RMB中所映射的RE由第一交织序列确定，第一交织序列由基序列确定，第一终端为至少一个终端中的任意一个终端，第一RMB集合包含至少一个RMB。
本申请提供的资源映射方法，基于一个基序列产生多个交织序列，并由不同交织序列确定终端传输信息所占用的RE，由于用以指示RE位置的交织序列均由同一基序列产生，接入网设备无需维护大量的随机种子，也不必针对每一终端均产生一个随机序列，使得映射RE传输信息的实现复杂度有所降低。
在一种可能的设计中，接入网设备获取至少一个终端的资源映射信息，可以具体实现为：接入网设备根据资源映射矩阵确定至少一个终端的资源映射信息，其中，资源 映射矩阵为M*N矩阵，M为正整数，N为正整数，资源映射矩阵包括多个交织序列，多个交织序列中的每一交织序列均由基序列经预设算法得到，多个交织序列包括第一交织序列，资源映射矩阵一行元素对应的至少一个交织序列分配给第二终端使用，一行中的第i列元素对应的交织序列用于确定第二终端在第i个RMB集合的每一RMB中所映射的RE，或者，资源映射矩阵一列元素对应的至少一个交织序列分配给第三终端使用，一列中的第j行元素对应的交织序列用于确定第三终端在第j个RMB集合的每一RMB中所映射的RE，第二终端、第三终端均为至少一个终端中的任意一个终端。
在一种可能的设计中，资源映射信息还用于指示至少一个终端中每一终端在第二RMB集合的每一RMB中所映射的RE，其中，第四终端在第二RMB集合的每一RMB中所映射的RE由第二交织序列确定，第二交织序列为资源映射矩阵中的一个交织序列，第一RMB集合和第二RMB集合至少存在一个不同的RE，第二交织序列与第一交织序列中至少存在一个不同的元素，第四终端为至少一个终端中的任意一个终端。这就意味着，可以动态改变调制符号在不同RMB集合中所占用的RE。参见图11，在第一个RMB集合(包含6个RMB)中，终端1的调制符号在每一RMB中占用的RE为RE#1、RE#2、RE#4、RE#6，在第二个RMB集合(包含1个RMB)中，终端1的调制符号在每一RMB中占用的RE为RE#2、RE#4、RE#5、RE#6，在第三个RMB集合(包含2个RMB)中，终端1的调制符号在每一RMB中占用的RE为RE#1、RE#4、RE#5。如此，终端在不同RMB集合的RMB中使用不同RE传输信息，可增强信息传输的安全性，同时，提升通信系统的抗干扰性能。

首先，给出本申请实施例涉及的通信系统架构示意图，如图1所示，该通信系统包括接入网设备、以及与该接入网设备通信的多个终端(例如图1中的终端1至终端6)。

本申请的说明书以及附图中的术语“第一”和“第二”等是用于区别不同的对象，或者用于区别对同一对象的不同处理，而不是用于描述对象的特定顺序。除非另有说明，“/”表示或的意思，例如，A/B可以表示A或B；本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A， 同时存在A和B，单独存在B这三种情况。“至少一个”包括一个和至少两个的情况。此外，本申请的描述中所提到的术语“包括”和“具有”以及它们的任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括其他没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。需要说明的是，本申请实施例中，“示例性的”或者“例如”等词用于表示作例子、例证或说明。本申请实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。

存储器203可以是只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)或者可存储信息和指令的其他类型的动态存储设备，也可以是电可擦可编程只读存储器(electrically erasable programmable read-only memory，EEPROM)、只读光盘(compact disc read-only memory，CD-ROM)或其他光盘存储、光碟存储(包括压缩光碟、激光碟、光碟、数字通用光碟、蓝光光碟等)、磁盘存储介质或者其他磁存储设备、或者能够用于携带或存储具有指令或数据结构形式的期望的程序代码并能够由计算机存取的任何其他介质，但不限于此。存储器可以是独立存在，通过通信线路202与处理器相连接。存储器也可以和处理器集成在一起。

如图3所示，首先从发射端角度给出本申请实施例的资源映射方法的大致流程：
信道编码单元将X UE-n个信息比特编码为Y UE-n个码字比特，其中，UE-n表示第n个终端(即上文中的用户设备user equipment，UE)，n取值为正整数。之后，Y UE-n个码字比特分别输入多个调制单元，每一调制单元的输入码字比特数为K UE-n＝Y UE-n/P，P为调制单元个数，每一调制单元将K UE-n个码字比特调制为一个调制符号(用Q UE-n表示)，P个调制单元将Y UE-n个码字比特调制为L UE-n个调制符号(调制符号Q UE-n1至调制符号Q UE-nL UE-n)。之后，调制符号被输入到映射单元，映射单元将一个调制符号映射到一个或多个RE上。
在本申请实施例中，一个终端可在T UE-n个RMB中传输调制符号，其中，每一RMB包含M UE-n个RE。因此，该终端在每一RMB中传输的调制符号数为N UE-n＝L UE-n/T UE-n。RMB指的是包含至少一个RE的资源映射块。示例性的，根据信道编码帧划分多个RMB，参见图11，示出了在一个信道编码子帧中划分RMB的示例，一个RMB可以包含6个RE，即M UE-n的取值为6。当然，还可以根据传输块(Transport Block，TB)或者码块(Code Block，CB)划分多个RMB，其原理可参考根据信道编码帧划分RMB的方式，这里不再赘述。
本申请实施例提供的资源映射方法可应用于为多个终端配置RE的场景中，以下实施例主要以多个终端中的如图1所示的终端1和终端2这两个终端为例来说明该方法，如图4所示，本申请实施例提供的资源映射方法包括如下步骤：
S401、接入网设备获取终端的资源映射信息。
其中，终端的资源映射信息用于指示终端在各个RMB中所映射的RE。
具体的，如图5所示，S401可以实现为如下步骤S4011至S4013：
(可选的)S4011、接入网设备根据基序列生成资源映射矩阵。
其中，基序列满足如下关系：π＝[α 1,α 2,...,α J]，π为基序列，基序列中元素α j的取值为整数，J为基序列包含的元素个数。资源映射矩阵为M*N矩阵，M为正整数，N为正整数。
可选的，该基序列可以例如但不限于为如下序列或者为如下序列的子序列：
1、自然序列：例如，基序列π＝Ω＝[0,1,2...,J-1]，Ω为自然序列。
2、自然序列的扩展序列：π＝[Ω，perm 1(Ω)，perm 2(Ω)...,perm t(Ω)]，perm t(Ω)为自然序列Ω的第t个重排序列。重排序列指的是对一个序列中的元素进行重新排序得到的序列。例如，一个序列为η＝[1,2,3，4]，该序列的一个重排序列例如为η 1＝[2,3，4，1]，该序列的另一重排序列例如为η 2＝[3，2，4，1]。当序列包含的元素个数不同时，序列的重排序列的个数可能不同，例如，包含3个元素的序列，其重排序列的个数可以例如为

个，包含4个元素的序列，其重排序列的个数可以例如为
Figure PCTCN2019103884-appb-000004
个。
3、自然序列的比特逆序序列：π＝[BitRev(Ω)]，BitRev(Ω)可由BitRev(Ω’)得到。
BitRev(Ω’＝[β(0),β(1),β(2),...,β(Ω’-1)]，β(i)为i的比特逆序值，即，当i的二进制展开为(b n-1,...,b 1,b 0)时，β(i)的二进制展开为(b 0,b 1,...,b n-1)。Ω’为序列BitRev(Ω’)中的元素个数，

之后，将BitRev(Ω’)中全部小于J的元素按照一定顺序取出，作为BitRev(Ω)的元素。
举例来说，当J取值为3时，基序列包含3个元素，假设基序列为π＝[0,1,2]。首先，计算序列BitRev(Ω’)中的元素个数Ω’，在2的整数次幂(例如1、2、4、8、16)中，大于J(3)的最小值为4，因此，Ω’取值为4。
接下来，计算BitRev(Ω’)＝BitRev(4)＝[β(0),β(1),β(2),β(3)]。由于0至3的二进制展开依次为(00、01、10、11)，因此，β(0)至β(3)的二进制展开依次为(00、10、01、11)，BitRev(4)＝[0,2,1,3]。假设按照从左到右的顺序取出BitRev(4)中小于J(3)元素，则最终得到的自然序列的比特逆序序列如下：
π＝[BitRev(Ω)]＝[BitRev(3)]＝[0,2,1]。
4、比特逆序序列的扩展序列：
π＝[BitRev(Ω),perm 1(BitRev(Ω)),perm 2(BitRev(Ω)),...,perm t(BitRev(Ω))]
其中，BitRev(Ω)为自然序列Ω的比特逆序序列，perm t(BitRev(Ω))为BitRev(Ω)的第t个重排序列。
5、伪随机序列：由预规定的随机种子产生的序列。
6、固定序列：当一个RMB包含的RE个数给定，则规定序列可以例如但不限于为如下序列中的任意一个：
若一个RMB包含2个RE，则固定序列例如为：
[1,2,2,1,1,2,2,1,1,2,2,1,1,2,2,1,…,1,2,2,1]。
若一个RMB包含4个RE，则固定序列例如为：
[1,2,3,4,1,3,2,4,1,4,2,3,1,2,3,4,1,3,2,4,1,4,2,3,1,2,3,4,…,1,2,3,4,1,3,2,4,1,4,2,3]。
若一个RMB包含5个RE，则固定序列例如为：
[1,2,3,4,5,1,3,5,2,4,1,2,5,3,4,1,5,3,2,4,1,2,4,3,5,1,2,3,4,5,…,1,2,3,4,5,1,3,5,2,4,1,2,5,3,4,
1,5,3,2,4,1,2,4,3,5]。
若一个RMB包含6个RE，则固定序列例如为：
[1,2,3,4,5,6,1,3,5,2,4,6,1,2,5,3,4,6,1,2,6,3,4,5,1,2,4,3,5,6,1,2,3,4,5,6,…,1,2,3,4,5,6,1,3,5,2,4,6,1,2,5,3,4,6,1,2,6,3,4,5,1,2,4,3,5,6]。
若一个RMB包含8个RE，则固定序列例如为：
[1,2,3,4,5,6,7,8,1,3,5,7,2,4,6,8,1,4,5,8,2,3,6,7,1,2,5,6,3,4,7,8,1,2,3,5,4,6,7,8,2,3,4,6,1,5,7,8,1,2,3,4,5,6,7,8,…,1,2,3,5,4,6,7,8,1,3,5,7,2,4,6,8,1,4,5,8,2,3,6,7,1,2,5,6,3,4,7,8,1,2,3,5,4,6,7,8,2,3,4,6,1,5,7,8]。
若一个RMB包含12个RE，则固定序列例如为：
[1,2,3,4,5,6,7,8,9,10,11,12,1,3,5,7,9,11,2,4,6,8,10,12,1,4,5,8,9,12,2,3,6,7,10,11,1,2,5,6,9,10,3,4,7,8,11,12,1,2,3,5,6,9,4,7,8,10,11,12,1,2,3,4,5,6,7,8,9,10,11,12,…,1,2,3,4,5,6,7,8,9,10,11,12,1,3,5,7,9,11,2,4,6,8,10,12,1,4,5,8,9,12,2,3,6,7,10,11,1,2,5,6,9,10,3,4,7,8,11,12,1,2,3,5,6,9,4,7,8,10,11,12]。
当然，以上固定序列还可以有其他形式，例如，当一个RMB包含4个RE时，固定序列还可以例如为：
[1,2,3,4,1,4,2,3,1,3,2,4,1,2,3,4,…,1,2,3,4,1,4,2,3,1,3,2,4,1,2,3,4]。
也就是说，由于固定序列中包含的元素个数不同，固定序列还可以扩展为其他形式，上述仅仅列举有限几个作为简单说明。
可选，上述自然序列还可以为π＝Ω＝[1,2...,J]，或者还可以为其他形式的序列，相应的，由该序列得到的其他序列也就不同于上文所列举的序列。
如上文所提及的内容，可以选取上述1至6中任一序列或者任一序列的一个子序列作为基序列。可选的，如果给定基序列包含的元素个数，则可以选取上述任意一个序列的J个元素作为基序列的元素。可选的，从上述任意一个序列中选取前J个元素作为基序列的元素，或者，选取上述任意一个序列的后J个元素作为基序列的元素，或者，选取上述任意一个序列的中间J个元素作为基序列的元素，又或者，按照预设的固定间隔选取上述任意一个序列的J个元素作为基序列的元素，再或者，选取上述任意一个序列的任意J个元素作为基序列的元素，本申请实施例不对基序列元素的选取方式做具体限制，除了接入网设备选取基序列的方式，基序列还可由协议规定。
可选的，基序列中元素的个数J可以例如但不限于为一个RMB包含RE个数的整数倍，一个RMB复用的终端个数的整数倍，一个RMB中待映射的全部调制符号数，本申请实施例对此不进行限制。
可选的，基序列可由接入网设备根据自身策略选取，也可以有协议预先规定，本申请实施例对此不进行限制。
本申请实施例提供多种形式的基序列，接入网设备可随机选取任意一种作为资源映射所使用的基序列，由于可供选择的基序列存在各种变形形式，因此，不易被第三方非法窃取，提升了使用基于基序列映射RE传输信息的安全性。
接入网设备按照预设规则对选取的或者由协议预规定的基序列进行循环移位操作，得到不同的交织序列，生成资源映射矩阵。
示例性的，资源映射矩阵满足如下关系：
Figure PCTCN2019103884-appb-000007
其中，A为资源映射矩阵，该资源映射矩阵中每一元素对应一个交织序列。
可选的，在资源映射矩阵中，每一行元素对应的多个交织序列均分配给一个终端使用，该一行元素中的第i列元素对应的交织序列用于确定终端在第i个RMB集合的每一RMB中所映射的RE。具体的，序列π n,c为终端n在第c个RMB集合的每一RMB中映射RE所使用的交织序列，也就是说，在第c个RMB集合的每一RMB中，终端映射RE所使用的交织序列相同，相应的，终端在该RMB集合的各个RMB中传输信息时占用的RE相同。示例性的，第c个RMB集合包含3个RMB，则终端在第一个RMB中使用交织序列1映射RE，在第二个RMB中也使用交织序列1映射RE，同样的，在第三个RMB中映射RE也使用交织序列1。
可选的，在资源映射矩阵中，每一列元素对应的多个交织序列均分配给一个终端使用，该一列元素中的第j行元素对应的交织序列用于确定终端在第j个RMB集合的每一RMB中所映射的RE。此时，A中序列π n,c为终端c在第n个RMB集合的每一RMB中映射RE所使用的交织序列。终端n或者终端c为接入网设备所服务的终端中的任意一个，包括例如但不限于为图1通信系统中的终端。
下文主要以将资源映射矩阵的一行元素对应的多个交织序列均分配给一个终端为例进行说明，在此统一说明，以下不再赘述。
交织序列π n,c中的元素可以指示终端传输信息所占用的RE，本申请实施例提供如下两种由交织序列π n,c指示RE的方式：
方式1：交织序列间接指示终端占用的RE，交织序列π n,c中的元素指示终端n在第c个RMB集合的每一RMB中映射RE所用的映射向量，该映射向量从映射向量池中选取，映射向量指示终端n的调制符号在第c个RMB集合的每一RMB中所映射的RE的位置。
映射向量池为包含全部可用映射向量的集合，接入网设备服务的终端均在该映射向量池中选取映射向量。
其中，映射向量满足如下关系：
Figure PCTCN2019103884-appb-000008
其中，re_vec为映射向量，L为每一RMB包含的RE数目，w m为终端的一个调制符号映射到一个RMB中第m个RE所需的权重。
方式2：交织序列直接指示终端传输信息时占用的RE，也就是，π n,c中的元素指示终端n的调制符号在第c个RMB集合的每一RMB中所映射的RE的位置。
当然，将一列元素对应的多个交织序列均分配给一个终端的情况下，上述资源映射矩阵A中，π n,c中的元素可间接指示RE位置，即所述π n,c中的元素指示所述终端c在第n个RMB集合的每一RMB中映射RE所用的映射向量，所述映射向量指示所述终端c的调制符号在第n个RMB集合的每一RMB中所映射的RE的位置。或者，所述π n,c中的元素直接指示所述终端c的调制符号在第n个RMB集合的每一RMB中所映射的 RE的位置。
可选的，产生资源映射矩阵的过程可由图6表示。其中，资源映射矩阵中每一元素对应的交织序列均可由基序列经循环移位得到，以π n,c+1和π n+1,c为例。假设在资源映射矩阵中，每一行的各列元素对应的交织序列之间的循环移位间隔为Δ 1，例如，第一行中，序列π 1,1和π 1,2之间的循环移位间隔为2，即π 1,1循环移位2位后可得到π 1,2，每一列的各行元素对应的交织序列之间的循环移位间隔为Δ 2。
首先，基序列经循环移位得到π 1,1，π 1,1再经过circshift(π 1,1,(n-1)Δ 2+c*Δ 1)可得到π n,c+1，其中，circshift(π n,c,Δ)表示将序列π n,c循环移位Δ位的运算。
同样的，π 1,1经过circshift(π 1,1,n*Δ 2+(c-1)Δ 1)可得到π n+1,c。
当然，也可以有基序列循环移位得到资源映射矩阵中任意一个位置的交织序列，再由该交织序列经循环移位得到资源映射矩阵中的其他全部交织序列，本申请实施例并不限制循环移位的具体实现方式。
可选的，Δ 1可设置为终端在一个RMB中待映射的调制符号个数，或者调制符号的整数倍，或者，可设置为终端在一个RMB中待映射的RE数，或者设置为其他可行的数值，或者待映射的RE的整数倍。类似的，也可以配置Δ 2的数值。
需要说明的是，在本申请实施例中，S4011为可选步骤，也就是说，接入网设备中的资源映射矩阵可由接入网设备按照本S4011生成，当然接入网设备也可以不执行S4011，在这种情况下，资源映射矩阵可由协议预先规定。
S4012、接入网设备根据资源映射矩阵为分别不同终端配置交织序列。
可选的，接入网设备随机从资源映射矩阵中选取一行元素，并将该行元素对应的多个交织序列配置给一个终端。例如，接入网设备为终端1配置上述A中的第一行元素对应的多个交织序列，其中，交织序列π 1,1为终端1在第一个RMB集合的每一RMB中映射RE所使用的交织序列，π 1,2为终端1在第二个RMB集合的每一RMB中映射RE所使用的交织序列，以此类推。接入网设备为终端2配置A中的第8行元素对应的多个交织序列，其中，交织序列π 8,1为终端2在第一个RMB集合的每一RMB中映射RE所用的交织序列，π 8,2为终端2在第二个RMB集合的每一RMB中映射RE所使用的交织序列，以此类推。
可选的，接入网设备按照轮询方式从资源映射矩阵中选取一行元素，即选取当前未被使用过的一行元素，并将该行元素对应的多个交织序列配置给一个终端。
当然，接入网设备还可以采用其他方式从资源映射矩阵中选取一行元素，并为终端配置该行元素对应的多个交织序列，本申请实施例对此不进行限制。
S4013、接入网设备根据配置给终端的交织序列确定该终端的资源映射信息。
可选的，资源映射信息包括例如但不限于以下信息的至少一种：交织序列的索引信息、交织序列长度(即交织序列包含元素的个数)信息、所占用RE的位置信息、所占用RE的数量、循环移位算法规则、用以表示不同RE位置的交织序列和/或者交织序列索引和/或交织序列的数量、用以指示不同RE位置的映射向量、映射向量的数量、映射向量的索引、基序列(或者基序列索引)、每一RMB集合包含的RMB个数，下文主要以资源映射信息为交织序列索引信息为例进行说明，这里做出统一说明，下 文不再赘述。
接入网设备可以根据配置给终端的交织序列确定该终端的交织序列索引。示例性的，终端的交织序列索引为交织序列的行号索引，例如，若接入网设备配置给终端的交织序列为资源映射矩阵A中第一行元素对应的多个交织序列，则终端的交织序列索引取值为1，若接入网设备配置给终端的交织序列为资源映射矩阵A中第二行元素对应的多个交织序列，则终端的交织序列索引取值为2，以此类推。
(可选的)S402、接入网设备向终端发送资源映射信息。
相应的，终端接收接入网设备发送的资源映射信息。
可选的，接入网设备通过RRC信令向终端发送资源映射信息，例如，在建立RRC连接时向终端发送资源映射信息，或者，接入网设备通过物理层信令向终端发送资源映射信息，例如，在物理下行控制信道(Physical Downlink Control Channel，PDCCH)中向终端发送资源映射信息，或者，通过广播消息，例如主信息块(master information block，MIB)消息向终端发送资源映射信息。
当然，终端除了可以从接入网设备获取诸如交织序列长度(即交织序列包含元素的个数)信息、传输信息所占用RE的数量、循环移位算法规则、基序列、每一RMB集合包含的RMB个数等信息，还可以由协议预先规定终端的上述信息，例如，由协议预先规定循环移位所使用的基序列，循环移位算法规则，需要说明的是，该基序列与接入网设备使用的基序列是同一基序列。循环移位算法规则与接入网设备的循环移位算法规则是同一算法规则。
S403、终端获取在传输信息时所映射(占用)的RE。
其中，终端传输信息所占用的RE指的是终端通过各个RMB中传输信息时各自占用的RE。
作为一种可能的实现方式，终端存储有与接入网设备中相同的资源映射矩阵，该资源映射矩阵可由协议规定，并分别配置在终端和接入网设备中。或者，该资源映射矩阵由接入网设备生成，并通过接入网设备和终端之间的信令交互配置给终端。
假设终端1、终端2在一个RMB中待映射的调制符号均为2个，分别为Q(UE-1,1)、Q(UE-1,2)、Q(UE-2,1)、Q(UE-2,2)，其中，UE-1表示终端1，UE-2表示终端2，每一调制符号映射到2个RE上。映射向量池为图7所示的一个映射向量的集合{re_vec}，该映射向量池包含多个映射向量组，每一组映射向量包含1个或多个映射向量，每一映射向量包含的元素个数可能相同，也可能不同。例如，可以将{re_vec}中的映射向量
Figure PCTCN2019103884-appb-000009
和
Figure PCTCN2019103884-appb-000010
划分到一个映射向量组中。
如下以资源映射信息为上述交织序列的索引信息为例说明终端如何在RMB中确定占用的RE。
其中，为便于理解，可由因子图表示RE映射过程，当交织序列直接指示和间接 指示RE时，因子图中不同节点具有不同含义。具体的，在交织序列中元素直接用于指示RE位置的情况下，因子图中的一个变量节点(Variable Node，VN)表示一个调制符号，一个功能节点(Function Node，FN)表示一个RE。在交织序列中元素用于指示映射向量，映射向量用于指示RE位置(即交织序列用于间接指示RE位置)的情况下，一个VN表示一个映射向量，一个FN表示一个RE。图8示出了交织序列中元素间接指示RE位置时的因子图，图9示出了交织序列中元素直接指示RE位置时的因子图。
参见图8，在交织序列间接指示RE位置的情况中，终端1在接收到接入网设备发送的交织序列索引信息后，在存储的资源映射矩阵A中查找交织序列索引信息所指示的行，假设为A中的第二行，且第二行元素对应的多个交织序列依次为交织序列1：[1,2,3,4,5,6]、交织序列2：[3,4,5,6,1,2]、交织序列3：[5,6,1,2,3,4]、交织序列4：[1,2,3,4,5,6]。
在第一个RMB集合的每一RMB中，例如在第一个RMB集合的第一个RMB中，终端1根据交织序列1中前两个元素的数值分别映射调制符号1和调制符号2，即Q(UE-1,1)和Q(UE-1,2)。具体的，终端1根据交织序列1中第一个元素的数值(即1)选择映射向量池中编号为1的映射向量(简称1号映射向量)，即
Figure PCTCN2019103884-appb-000011
该1号映射向量表示终端1通过RMB中的第一、第二个RE传输第一个调制符号Q(UE-1,1)，并且，通过第一个RE传输的调制符号权重为w 1，通过第二个RE传输的调制符号权重为w 2。终端1根据交织序列1中第二个元素的数值(即2)选择映射向量池中的1号映射向量，即
Figure PCTCN2019103884-appb-000012
2号映射向量表示终端1通过RMB中的第四、第六个RE传输第二个调制符号Q(UE-1,2)，并且，通过第四个RE传输的调制符号权重为w 4，通过第六个RE传输的调制符号权重为w 6。同样的，在第一个RMB集合的其他每一RMB中，终端1也将调制符号映射到第一、第二、第四、第六个RE上，并且，映射到各个RE上的调制符号权重相同。
类似的，在第二个RMB集合的每一RMB中，终端1根据交织序列2中前2个元素数值(3、4)选择映射向量池中的3、4号映射向量，以此指示终端通过第二个RMB集合的每一RMB中的第几个RE传输2个调制符号，并指示通过各个RE传输的调制符号的权重。终端1在第三个RMB集合、第四个RMB集合中映射RE的方式可参见终端1在第一、第二个RMB集合中映射RE的描述。终端2在各个RMB集合中映射RE的方式也可参见终端1在各个RMB集合中映射RE的相关内容，这里均不再赘述。 图8示例性示出了终端1和终端2在第一个RMB集合的每一RMB中传输信息时占用(映射)的RE。
在交织中元素用于直接指示RE位置的情况下，参见图9，可用的RE构成RE池，RE池包括多个RE组，每一RE组包括多个RE。示例性的，RE组可以为一个子带(subband)，该RE组包含的RE个数即一个子带包含的RE个数，RE还可以为一个RB，该RE组包含的RE个数即一个RB包含的RE个数(例如12*7＝84个)。此时，映射RE的流程如下：
在接收到接入网设备发送的交织序列索引信息后，终端1在存储的资源映射矩阵A中查找终端1所使用的交织序列，假设为A中的第二行，且第二行元素对应的多个交织序列依次为交织序列1：[1,2,4,6,3,5]、交织序列2：[4,6,3,5,1,2]、交织序列3：[3,5,1,2,4,6]、交织序列4：[1,2,4,6,3,5]，不同交织序列可用于指示终端1在不同RMB中占用的RE。具体的，终端1根据交织序列1中前两个元素(即1、2)映射调制符号1Q(UE-1,1)，将终端1的调制符号1映射到RMB中的第一、第二个RE上，并根据交织序列1中第三、第四个元素(即4、6)将终端1的调制符号2映射到RMB中的第四、第六个RE上。类似的，终端2的RE映射方式可参见终端1的RE映射方式，这里不再赘述。
可选的，上述映射RE过程还可用如下公式表示：
Figure PCTCN2019103884-appb-000013
其中，该公式中各个参数的含义可参见上文描述，这里不再赘述。
可选的，上述终端1的第一个调制符号Q(UE-1,1)映射RE的详细过程可用图10表示，将调制符号Q(UE-1,1)乘以权重w 1，并将乘以权重w 1后的该调制符号映射到RE#1，将调制符号Q(UE-1,1)乘以权重w 2，并将乘以权重w 2后的该调制符号映射到RE#2。终端1的第二个调制符号映射RE的过程，以及终端2的两个调制符号RE的过程可参见图10所示的调制符号映射RE的内容，这里不再赘述。
需要说明的是，在本申请实施例中，可以动态改变调制符号在不同RMB集合中所占用的RE。参见图11，在第一个RMB集合(包含6个RMB)中，终端1的调制符号占用的RE为RE#1、RE#2、RE#4、RE#6，在第二个RMB集合(包含1个RMB)中，终端1的调制符号占用的RE为RE#2、RE#4、RE#5、RE#6，在第三个RMB集合(包含2个RMB)中，终端1的调制符号占用的RE为RE#1、RE#4、RE#5。类似的，终端2的调制符号在不同RMB集合的每一RMB中占用的RE也可以不同。如此， 终端在不同RMB集合中使用不同RE传输信息，可增强信息传输的安全性，同时，提升通信系统的抗干扰性能。
可选的，终端接收的接入网设备发送的资源映射信息还可以例如为交织序列，使得终端直接通过交织序列获知在不同RMB集合中所占用的RE。
S404、终端在所映射的RE上传输信息。
当终端获知传输信息所占用的RE后，终端可通过相应RE上传输信息。
其中，终端传输信息包括终端向接入网设备发送上行信息和终端接收接入网设备发送的下行信息。以接入网设备为终端配置在第一RMB集合的各个RMB中所映射的RE为例，若上述接入网设备为终端配置的RE是上行传输所用的RE，则终端在第一RMB集合的各个RMB中所映射的RE上向接入网设备发送上行信息，相应的，接入网设备在第一RMB集合的各个RMB中所映射的RE上接收终端发送的上行信息。若上述接入网设备为终端配置的RE是下行传输所用的RE，则后续接入网设备与终端进行交互时，接入网设备在第一RMB集合的各个RMB中所映射的RE上向终端发送下行信息，相应的，终端在第一RMB集合的各个RMB中所映射的RE上接收接入网设备发送的下行信息。以接入网设备为终端配置的RE为上行传输所用RE为例，仍参见图11，在第一个RMB集合的每一RMB中，终端1均通过第一、第二、第四、第六个RE向接入网设备发送上行信息，相应的，在第一个RMB集合的每一RMB中，接入网设备均通过第一、第二、第四、第六个RE接收终端1发送的上行信息。
本申请实施例提供的资源映射方法，基于一个基序列产生多个交织序列，并由不同交织序列确定终端传输信息所占用的RE，由于用以指示RE位置的交织序列均由同一基序列产生，接入网设备无需维护大量的随机种子，也不必针对每一终端均产生一个随机序列，使得映射RE传输信息的实现复杂度有所降低。
同时，参见表1，为本申请实施例的资源映射方法的实施仿真结果。
表1
Figure PCTCN2019103884-appb-000014
Figure PCTCN2019103884-appb-000015
其中，表1的第1列中的O1I3表示接收机外迭代次数为1，内迭代次数为3，O2I3表示接收机外迭代次数为2，内迭代次数为3，以此类推。表1中的数据表示在不同的终端数、频谱效率、接收机外迭代次数、接收机内迭代次数条件下，达到相同的传输信息的块误码率(Block Error Ratio，BLER)时，采用本申请实施例的资源映射方法与现有技术相比的信噪比(Signal-to-noise ratio，SNR)差距。从表1可知，表1中的SNR差别为负数，表示本申请实施例的资源映射方法在所传输信息的达到BLER目标时，信噪比更低。并且，当系统负载升高时，即终端数由4升至8时，SNR差别更显著，通信系统的性能增益较大。
