Description

资源分配方法/装置/设备及存储介质 技术领域
本公开涉及通信技术领域，尤其涉及一种资源分配方法、装置、设备及存储介质。
背景技术
近些年来，随着频谱资源的日益紧缺，激发了大量频谱共享技术的迅速发展。由于雷达和通信通常具有不同的频段，而频谱资源的紧缺促使雷达和通信功能的有机融合，即通信感知一体化(Integrated Sensing and Communication，ISAC)系统。通感系统建立在雷达系统和通信系统的有机融合基础上，其原因是雷达系统和通信系统有多个共通之处，例如可共用射频前端等硬件设备，相似的频域信号处理算法，波形设计等等。
相关技术中，当通感系统中具有多个数据接收端时，如何进行子载波分配也是一项值得研究的问题。一种简单而可行的方法是采用子载波连续分配，即某个数据接收端占据一段连续的频谱资源，其他数据接收端占据其他连续的频谱资源。其中，假设一个符号对应的子载波总数为784，通感系统中具有4个数据接收端，分别为数据接收端#A、数据接收端#B、数据接收端#C、数据接收端#D，其中，图1和图2为相关技术中数据接收端#A的时频资源的示意图，其中，图1中不同OFDM符号时间内子载波位置固定不变，图2中不同OFDM符号时间内子载波位置随机变化。以及，图1和图2中数据接收端#A占用的子载波用白色部分表示，数据接收端#A未占用的子载波用黑色部分表示。
但是，相关技术中的方法会使得数据接收端的子载波之间的信号相关性较大，从而会影响对于各个数据接收端的探测效果。具体的，当调制方式为正交相移键控(Quadrature Phase Shift Keying，QPSK)，信噪比(Signal to Noise Ratio，SNR)设置为0dB时，图3为图1所示的分配方法下基站对数据接收端#A、数据接收端#B、数据接收端#C、数据接收端#D的雷达探测立体图和平面图，其中，雷达探测立体图为图3中的3-1，雷达探测平面图为图3中的3-2；图4为图2所示的分配方法下基站对数据接收端#A、数据接收端#B、数据接收端#C、数据接收端#D的雷达探测立体图和平面图，其中，雷达探测立体图为图4中的4-1，雷达探测平面图为图4中的4-1。由图3和图4可知，当采用图1所示的分配方式为数据接收端分配频域资源后，探测数据接收端时在距离轴(纵轴)上具有距离扩展现象，当采用图2所示的分配方式为数据接收端分配频域资源后，探测数据接收端时在速度轴(横轴)上具有速度扩展现象，次峰较高，旁瓣较多，则会使得探测效果不理想，无法准确探测数据接收端的距离和速度。
发明内容

本公开一方面实施例提出的资源分配方法，包括：

发送模块，用于发送配置信息，所述配置信息用于确定分配的资源。
本公开又一方面实施例提出的一种通信装置，所述装置包括处理器和存储器，所述存储器中存储有计算机程序，所述处理器执行所述存储器中存储的计算机程序，以使所述装置执行如上一方面实施例提出的方法。
本公开又一方面实施例提出的通信装置，包括：处理器和接口电路；

所述处理器，用于运行所述代码指令以执行如一方面实施例提出的方法。
本公开又一方面实施例提出的计算机可读存储介质，用于存储有指令，当所述指令被执行时，使如一方面实施例提出的方法被实现。
综上所述，在本公开实施例提供的资源分配方法、装置、设备及存储介质之中，会先确定资源分配方案为：基于CPP交织器进行资源分配；之后，按照资源分配方案进行资源分配，并发送配置信息，该配置信息用于确定分配的资源。由此可知，本公开实施例之中，在为数据接收端分配资源时引入CPP交织器，采用CPP交织器将子载波序列进行扰乱，通过构建伪随机序列进而将子载波随机分配给多用户，由此可以避免为数据接收端分配连续的频域资源，提升通感系统感知能力，更有利于分辨通感系统中的多个动目标。

下面参考附图对本公开实施例所提供的资源分配方法、装置、设备及存储介质进行详细描述。
图5为本公开实施例所提供的一种资源分配方法的流程示意图，如图5所示，该资源分配方法可以包括以下步骤：
步骤501、确定资源分配方案为：基于CPP交织器进行资源分配。
本公开实施例的方法可以适用于有源雷达系统和/或无源雷达系统。其中，在有源雷达系统和无源雷达系统中均可以包括数据发送端、数据接收端和回波接收端，其中，基站或用户设备(User Equipment，UE)可以作为数据发送端和回波接收端，UE可以作为数据接收端。
以及，在有源雷达系统中，同一设备可以同时作为数据发送端和回波接收端。在无源雷达中，不同设备分别作为数据发送端和回波接收端，且回波接收端可有多个。其中，数据发送端发送比特数据给数据接收端，数据接收端作为接收机完成通信功能。数据发送端发送比特数据照射在数据接收端上产生的回波信号回传至回波接收端(即数据发送端)，回波接收端通过雷达处理器对数据接收端进行速度距离等信息探测，完成雷达功能。此外，本公开实施例的方法还可以是用于主动式雷达系统和/或被动式雷达系统。
需要说明的是，在本公开的一个实施例之中，UE可以是指向用户提供语音和/或数据连通性的设备。终端设备可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，UE可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，UE也可以是无人飞行器的设备。或者，UE也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，UE也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
进一步地，在本公开的一个实施例之中，上述的确定资源分配方案的方法可以包括以下至少一种：
获取网络设备(基站和/或核心网设备)发送的资源分配方案；
获取基站发送的资源分配方案，其中，该资源分配方案为核心网设备预先配置至基站的；
获取基站发送的资源分配方案，其中，该资源分配方案为其他基站预先配置至该基站的；
基于协议约定确定资源分配方案；
自行确定所述资源分配方案，即根据实际情况或者需求自行确定要采用的配置方案。
步骤502、按照资源分配方案进行资源分配。
具体的，在本公开的一个实施例之中，主要是利用CPP交织器对通感系统中的数据接收端进行频域资源分配。其中，关于该部分内容会在后续实施例进行详细介绍。
步骤503、发送配置信息，该配置信息用于确定分配的资源。
其中，在本公开的一个实施例之中，该配置信息可以包括各个数据接收端对应的频域资源。
综上所述，在本公开实施例提供的资源分配方法之中，会先确定资源分配方案为：基于CPP交织器进行资源分配；之后，按照资源分配方案进行资源分配，并发送配置信息，该配置信息用于确定分配的资源。由此可知，本公开实施例之中，在为数据接收端分配资源时引入CPP交织器，采用CPP交织器将子载波序列进行扰乱，通过构建伪随机序列进而将子载波随机分配给多用户，由此可以避免为数据接收端分配连续的频域资源，提升通感系统感知能力，更有利于分辨通感系统中的多个动目标。
图6为本公开实施例所提供的一种资源分配方法的流程示意图，如图6所示，该资源分配方法可以包括以下步骤：
步骤601、确定资源分配方案为：基于CPP交织器进行资源分配。
其中，关于步骤601的详细介绍可以参考上述实施例描述，本公开实施例中在此不做赘述。
步骤602、将符号(如正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号)中的N个子载波索引依次进行排列以得到第一子载波索引序列。
其中，在本公开的一个实施例之中，可以符号中的N个子载波索引按照从大到小的顺序或者从小到大的顺序来排列，如得到的第一子载波索引序列可以为(0,1,...,N-1)。
步骤603、利用CPP交织器对第一子载波索引序列进行交织处理得到第二子载波索引序列。
具体的，在本公开的一个实施例之中，上述交织处理的方法主要可以包括以下步骤：
步骤a、确定CPP交织器的交织参数。
其中，在本公开的一个实施例之中，该CPP交织器的交织参数可以包括以下至少一种：
CPP交织器计算公式；
CPP交织器对应的分解公式；
CPP交织器计算公式中的参数取值规则。
具体而言，上述的CPP交织器计算公式可以为：
π(i)＝(f 1·i+f 2·i 2+f 3·i 3)mod N        (1)
其中，i用于指示第二子载波索引序列的第i位，π(i)是第二子载波索引序列的第i位的取值，f 1、f 2和f 3是CPP交织器的三个参数，其中，f 1、f 2和f 3的取值基于所述参数取值规则确定。
上述的CPP交织器对应的分解公式可以为：
Figure PCTCN2022092557-appb-000001
其中，ω(N)为正整数，p i是N的因数，α N,i是对应的指数。
上述的参数取值规则可以为：
Figure PCTCN2022092557-appb-000002
Figure PCTCN2022092557-appb-000003
则由上述参数取值规则可知，当3|(p i-1)，α K,i≥1时，f 1、f 2和f 3的取值需满足参数取值规则：f 1≠0 mod p i,f 2＝0 mod p i,f 3＝0 mod p i。当p 1＝2，α N,1＞1，p 2＝3，α N,2＝1时，f 1、f 2和f 3的取值需满足参数取值规则：f 1＝1 mod 2,f 2＝0 mod 2,f 3＝0 mod 2和(f 1+f 3)≠0 mod 3,f 2＝0 mod 3。
以及，在本公开的一个实施例之中，上述的确定CPP交织器的交织参数的方法可以包括以下至少一种：
获取网络设备发送的CPP交织器的交织参数；
获取基站发送的CPP交织器的交织参数，其中，该CPP交织器的交织参数为核心网设备预先配置至所述基站的；
获取基站发送的CPP交织器的交织参数，其中，该CPP交织器的交织参数为其他基站预先配置至所述基站的；
基于协议约定确定CPP交织器的交织参数。
步骤b、基于分解公式对N进行分解以确定出p i和α N,i的值。
示例的，在本公开的一个实施例之中，假设N＝12，则基于分解公式(2)可以将N分解为：N＝12＝2 2*3；此时，可以确定p 1＝2、p 2＝3，α N,1为2(即α N,1＞1)、α N,2＝1。
步骤c、基于p i和α N,i的值以及参数取值规则确定f 1、f 2和f 3的取值。
具体的，可以基于p i和α N,i的值确定出f 1、f 2和f 3的取值需满足的参数取值规则，之后，基于f 1、f 2和f 3的取值需满足的参数取值规则确定出f 1、f 2和f 3的取值。
示例的，假设当N为12，被分解为：N＝12＝2 2*3时，可以确定f 1＝557，f 2＝120和f 3＝600。
步骤d、基于CPP交织器计算公式计算出第二子载波索引序列。
具体的，可以将上述步骤c中确定出的f 1、f 2和f 3的取值带入上述CPP交织器计算公式(1)中，并基于CPP交织器计算公式(1)计算出第二子载波索引序列。
示例的，假设未交织的第一子载波索引序列为(0,1,2,3,4,5,6,7,8,9,10,11)，CPP交织器的交织参数设置为f 1＝557，f 2＝120和f 3＝600则第二子载波索引序列可以(0,5,10,3,8,1,6,11,4,9,2,7)。
步骤604、划分第二子载波索引序列中的子载波索引以进行分组得到K个子载波组，其中，K为通感系统中数据接收端的数量，每个子载波组中包括至少一个第一子载波索引序列。
需要说明的是，在本公开的一个实施例之中，K个子载波组应满足以下条件：
响应于N可被K整除，K个子载波组内所包含的子载波索引的数量相同(如该数量可以为N被K整除后的值)；
响应于N不可被K整除，K个子载波组中的d个子载波组内所包含的子载波索引的数量相同，其他子载波组内所包含的子载波索引的数量相同，且d个子载波组内所包含的子载波索引的数量比其他子载波组内所包含的子载波索引的数量多1，其中，d为N对K取模后的值。以及，d个子载波组内所包 含的子载波索引的数量可以为N除以K的商的整数加1，其他子载波组内所包含的子载波索引的数量可以为N除以K的商的整数。
示例的，在本公开的一个实施例之中，假设N为12，K为3，N可被K整除，此时可以将第二子载波索引序列分3个子载波组，且该3个子载波组内所包含的子载波索引的数量相同，如可以为4。基于此，假设(0,5,10,3,8,1,6,11,4,9,2,7)为第二子载波索引序列，则此时可以将第二子载波索引序列中的前4个子载波索引划分为子载波组#1，子载波组#1为(0,5,10,3)，将第二子载波索引序列中的第5-8个个子载波索引划分为子载波组#2，子载波组#2为(8,1,6,11)，，将第二子载波索引序列中的第9-12个个子载波索引划分为子载波组#2，子载波组#2为(4,9,2,7)。
示例的，在本公开的另一个实施例之中，假设N为12，K为7，N不可被K整除，则确定N对K取模后的值d＝5，此时可以将第二子载波索引序列分7个子载波组，且该7个子载波组中的某5个子载波组内所包含的子载波索引的数量相同，该7个子载波组中的剩余的2个子载波组内所包含的子载波索引的数量与该某5个子载波组内所包含的子载波索引的数量不同，同时该某5个子载波组内所包含的子载波索引的数量比剩余的2个子载波组内所包含的子载波索引的数量多1。基于此，假设(0,5,10,3,8,1,6,11,4,9,2,7)为第二子载波索引序列，则此时可以将第二子载波索引序列中的前2个子载波索引划分为子载波组#1，子载波组#1为(0,5)，将第二子载波索引序列中的第3个至第4个子载波索引划分为子载波组#2，子载波组#2为(10,3)，将第二子载波索引序列中的第5个至第6个子载波索引划分为子载波组#3，子载波组#3为(8,1，将第二子载波索引序列中的第7个至第8个子载波索引划分为子载波组#4，子载波组#4为(6,11)，将第二子载波索引序列中的第9个至第10个子载波索引划分为子载波组#5，子载波组#5为(4,9)，将第二子载波索引序列中的第11个子载波索引划分为子载波组#6，子载波组#6为(2)，将第二子载波索引序列中的第12个子载波索引划分为子载波组#7，子载波组#7为(7)。
或者，可以将第二子载波索引序列中的第1个子载波索引和倒数第5个子载波索引划分为子载波组#1，子载波组#1为(0,11)；将第二子载波索引序列中的2和倒数第4个子载波索引划分为子载波组#2，子载波组#2为(5,4)；将第二子载波索引序列中的第3和倒数第3个子载波索引划分为子载波组#3，子载波组#3为(10,9)；将第二子载波索引序列中的第4和倒数第2个子载波索引划分为子载波组#4子载波组#4为(3,2)；将第二子载波索引序列中的第5和最后1个子载波索引划分为子载波组#5，子载波组#5为(8,7)；将第二子载波索引序列中的第6个子载波索引划分为子载波组#6，子载波组#6为(1)；将第二子载波索引序列中的第7个子载波索引划分为子载波组#7，子载波组#7为(6)。
即在本公开的实施例之中可以对第二子载波索引序列中的子载波索引按照先后顺序划分以得到K个子载波组，或者，不按照先后顺序划分来K个子载波组。
步骤605、为每个数据接收端分配一个子载波组，其中，每个子载波组中子载波索引对应的子载波为分配至所述数据接收端的频域资源。
其中，在本公开的一个实施例之中，可以为第K个数据接收端分配第K个子载波组。示例的，假设通感系统中具备两个数据接收端，分别为数据接收端#A和数据接收端#B，以及，得到的K个子载波组为：子载波组#1和子载波组#2。则可以为数据接收端#A分配子载波组#1，为数据接收端#B分配子载波组#2，此时，数据接收端#A的频域资源即为子载波组#1中子载波索引对应的子载波，数据接收端#B的频域资源即为子载波组#2中子载波索引对应的子载波。
步骤606、发送配置信息，该配置信息用于确定分配的资源。
其中，在本公开的一个实施例之中，该配置信息可以包括各个数据接收端对应的频域资源。例如，该配置信息包括：子载波组#1为数据接收端#A的频域资源，子载波组#2为数据接收端#B的频域资源。
则由上述步骤602和603可知，本公开实施例之中，会利用CPP交织器交织处理顺序排列的第一子载波索引序列以打乱顺序，得到第二子载波索引序列，其中，该第二子载波索引序列中的子载波索引未按照顺序排列。之后，通过执行步骤604和605来分组第二子载波索引序列得到子载波组，并将子载波组分配至数据接收端。其中，由于第二子载波索引序列中的子载波索引未按照顺序排列，则分组得到的子载波组中的子载波索引也应当是未按照顺序排列的，从而可以为各个数据接收端的分配非连续的子 载波，则后续数据接收端基于该非连续的子载波进行通信时，可以降低数据接收端的各个子载波之间的信号相关性，确保了对于数据接收端的探测效果。
此外，在本公开实施例之中，在利用基于PP(Permutation Polynomial,置换多项式)的交织器进行交织处理时，由于基于PP的交织器算法具有完整的代数结构，高效的硬件实现(速度快，存储量小)以及良好的误码率(Bit Error Rate,BER)性能，则可以确保交织处理的效率和准确度，进而可以确保后续能够高效且准确的进行资源分配。
综上所述，在本公开实施例提供的资源分配方法之中，会先确定资源分配方案为：基于CPP交织器进行资源分配；之后，按照资源分配方案进行资源分配，并发送配置信息，该配置信息用于确定分配的资源。由此可知，本公开实施例之中，在为数据接收端分配资源时引入CPP交织器，采用CPP交织器将子载波序列进行扰乱，通过构建伪随机序列进而将子载波随机分配给多用户，由此可以避免为数据接收端分配连续的频域资源，提升通感系统感知能力，更有利于分辨通感系统中的多个动目标。
图7a为本公开实施例所提供的一种资源分配方法的流程示意图，如图7a所示，该资源分配方法可以包括以下步骤：
步骤701、确定资源分配方案为：基于CPP交织器进行资源分配。
步骤702、将符号中的N个子载波索引依次进行排列以得到第一子载波索引序列。
步骤703、利用CPP交织器对第一子载波索引序列进行交织处理得到第二子载波索引序列。
步骤704、划分第二子载波索引序列中的子载波索引以进行分组得到K个子载波组，其中，K为通感系统中数据接收端的数量，每个子载波组中包括至少一个第一子载波索引序列。
其中，关于步骤701-704的详细介绍可以参考上述实施例描述，本公开实施例中在此不做赘述。
步骤705、为每个数据接收端分配一个子载波组，其中，每个子载波组中子载波索引对应的子载波为分配至所述数据接收端的频域资源，且同一数据接收端在不同符号下被分配的频域资源相同。
其中，在本公开的一个实施例之中，假设通感系统基本参数如表1所示，以及，假设通感系统中有A和B共2个UE作为数据接收端，其中，2个UE的速度和距离信息如表2所示。
表1通感系统基本参数
参数名称 数值
载波频率 24GHz
子载波间隔 60kHz
子载波数量 784
总符号带宽 47MHz
OFDM符号数量 560
OFDM前缀持续时间 1.17us
OFDM符号时间 16.67us
完整OFDM符号持续时间 17.84us

表2各UE速度信息与距离信息
UE 距离(m) 速度(m/s)
A 120 -30
B 120 30
C 40 -30
D 40 30
则基于表1中的基本参数可确定，UE#A、UE#B、UE#C和UE#D各自占用N＝784个子载波中的196个，且UE#A、UE#B、UE#C和UE#D的子载波索引由CPP交织器计算得到，以及，在560个OFDM符号时间内，UE#A、UE#B、UE#C和UE#D的子载波索引不变。其中，图7b本公开实施例所提供的一种采用图7a所示的方法分配资源时，UE#A的时频资源示意图，其中，UE#A占用的子载波用白色部分表示，UE#A未占用的子载波用黑色部分表示。需要说明的是，图7b是在f 1＝293，f 2＝756，f 3＝896的情况下基于CPP交织器计算公式进行资源分配时所得到的示意图，以及，图7c为本公开实施例所提供的一种采用图7a所示的方法下对UE的雷达探测立体图和平面图，其中，雷达探测立体图为图7中的c-1，雷达探测平面图为图7中的c-2。由图7c可知，当采用图7a所示的分配方式为UE分配频域资源后，探测UE时，虽然旁瓣较为明显，但是明显缓解了在距离轴(纵轴)上的距离扩展现象，从而一定程度上确保了探测效果。
步骤706、发送配置信息，该配置信息用于确定分配的资源。
其中，在本公开的一个实施例之中，该配置信息可以包括各个数据接收端对应的频域资源。例如，该配置信息包括：子载波组#1为数据接收端#A的频域资源，子载波组#2为数据接收端#B的频域资源。
综上所述，在本公开实施例提供的资源分配方法之中，会先确定资源分配方案为：基于CPP交织器进行资源分配；之后，按照资源分配方案进行资源分配，并发送配置信息，该配置信息用于确定分配的资源。由此可知，本公开实施例之中，在为数据接收端分配资源时引入CPP交织器，采用CPP交织器将子载波序列进行扰乱，通过构建伪随机序列进而将子载波随机分配给多用户，由此可以避免为数据接收端分配连续的频域资源，提升通感系统感知能力，更有利于分辨通感系统中的多个动目标。
图8a为本公开实施例所提供的一种资源分配方法的流程示意图，如图8a所示，该资源分配方法可以包括以下步骤：
步骤801、确定资源分配方案为：基于CPP交织器进行资源分配。
步骤802、将符号中的N个子载波索引依次进行排列以得到第一子载波索引序列。
步骤803、利用CPP交织器对第一子载波索引序列进行交织处理得到第二子载波索引序列。
步骤804、划分第二子载波索引序列中的子载波索引以进行分组得到K个子载波组，其中，K为通感系统中数据接收端的数量，每个子载波组中包括至少一个第一子载波索引序列。
其中，关于步骤801-804的详细介绍可以参考上述实施例描述，本公开实施例中在此不做赘述。
步骤805、为每个数据接收端分配一个子载波组，其中，每个子载波组中子载波索引对应的子载波为分配至所述数据接收端的频域资源，且同一数据接收端在不同符号下被分配的频域资源不同。
其中，在本公开的一个实施例之中，假设通感系统基本参数如上表1所示，以及，假设通感系统中有A和B共2个UE作为数据接收端，其中，2个UE的速度和距离信息如上表2所示。
则基于表1中的基本参数可确定，UE#A、UE#B、UE#C和UE#D各自占用N＝784个子载波中的196个，且UE#A、UE#B、UE#C和UE#D的子载波索引由CPP交织器计算得到，以及，在560个OFDM符号时间内，UE#A、UE#B、UE#C和UE#D的子载波索引发生改变。其中，图8b本公开实施例所提供的一种采用图8a所示的方法分配资源时，UE#A的时频资源示意图，其中，UE#A占用的子载波用白色部分表示，UE#A未占用的子载波用黑色部分表示。需要说明的是，图8b是在f 1＝293，f 2＝756，f 3＝896的情况下基于CPP交织器计算公式进行资源分配时所得到的示意图，以及，图8c为本公开实施例所提供的一种采用图8a所示的方法下对UE的雷达探测立体图和平面图，其中，雷达探测立体图为图8中c-1，雷达探测平面图为图8中c-2。由图8c可知，当采用图8a所示的分配方式为UE分配频域资源后，探测UE时，没有明显的侧峰，可以更清晰地分辨出两个UE，探测效果较优。
步骤806、发送配置信息，该配置信息用于确定分配的资源。
其中，在本公开的一个实施例之中，该配置信息可以包括各个数据接收端对应的频域资源。例如，该配置信息包括：子载波组#1为数据接收端#A的频域资源，子载波组#2为数据接收端#B的频域资源。
综上所述，在本公开实施例提供的资源分配方法之中，会先确定资源分配方案为：基于CPP交织器进行资源分配；之后，按照资源分配方案进行资源分配，并发送配置信息，该配置信息用于确定分配的资源。由此可知，本公开实施例之中，在为数据接收端分配资源时引入CPP交织器，采用CPP交织器将子载波序列进行扰乱，通过构建伪随机序列进而将子载波随机分配给多用户，由此可以避免为数据接收端分配连续的频域资源，提升通感系统感知能力，更有利于分辨通感系统中的多个动目标。
此外，以数据发送端为基站，数据接收端为UE为例，对上述图5-图8a的方法的执行主体进行介绍。
其中，在本公开的一个实施例之中，可以是作为数据发送端的基站执行上述图5-图8a的方法，即：基站确定资源分配方案为：基于CPP交织器进行资源分配，并基于该资源分配方法分配资源，之后，将用于确定分配的资源的配置信息发送至UE(即数据接收端)，UE基于该配置信息确定为其分配的频域资源。其中，基站确定资源分配方案的方法可以为以下至少一种：基于协议约定确定资源分配方案、获取核心网设备发送的资源分配方案、获取其他基站发送的资源分配方案(其中，其他基站的资源分配方案为核心网设备配置的或者另外的基站配置的)、基站自行确定所述资源分配方案。以及，需要说明的是，在本公开的一个实施例之中，作为数据发送端的基站还可以直接将其所确定的资源分配方案发送至UE，以便UE可以基于该资源分配方案确定出为其所分配的频域资源。
在本公开的另一个实施例之中，上述图5-图8a的方法可以是作为数据发送端的基站和作为数据接收端的UE分别执行。即：基站和UE均确定出资源分配方案为：基于CPP交织器进行资源分配，并均基于该资源分配方案分配资源。其中，UE确定资源分配方案的方法可以为：基于协议约定确定资源分配方案，和/或，UE获取基站发送的资源分配方案。
