Description

子信道的配置方法、通信节点及存储介质 技术领域
本申请涉及通信技术领域，例如涉及一种子信道的配置方法、通信节点及存储介质。
背景技术
对于非授权频段上的边链路(sidelink，SL)通信，一般地，基于载波配置带宽部分(Bandwidth Part，BWP)，在BWP内配置一个或者多个SL资源池(以下简称为资源池)，一个资源池可以包含多个资源块集合(Resource Block set，RB set)。通常，相邻的RB set之间留有保护带以避免不同RB set上的传输相互干扰。当相邻的RB set都空闲(即没有被其他设备占用)时，与仅仅使用RB set内的资源相比，如果相邻的RB set以及它们之间的保护带都可以使用，则传输可以达到更高的资源利用率。然而，当UE使用一个RB set时，相邻的RB set可能被其他设备占用，尤其是可能被其它异系统的设备占用，为了避免相邻RB set之间产生干扰，所以通常要保留保护带的资源不被使用。因此如何将保护带利用起来是亟需解决的问题。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。下文中将结合附图对本申请的实施例进行详细说明。
SL通信包括车用无线通信技术(Vehicle to Everything，V2X)通信、用户设备(User Equipment，UE)与UE直接通信(Device to Device，D2D)等，可以工作在授权频谱、智能交通系统(Intelligent Traffic Systems，ITS)频谱。在 将来，SL通信也可以工作在非授权频谱。
对于授权频段上的SL通信，BWP内配置一个或者多个资源池，资源池在频域上包含多个连续的资源块(Resource Block，RB)，这些RB被划分为一个或多个子信道，每个子信道包含相同数量个RB，SL的资源分配是基于资源池上子信道进行的，每个SL传输占用频域上连续的一个或多个子信道。
对于非授权频段上的SL通信，BWP内配置一个或者多个资源池，一个资源池可以包含多个RB set。通常，相邻的RB set之间留有保护带以避免不同RB set上的传输相互干扰。当相邻的RB set都空闲(即没有被其他设备占用)时，与仅仅使用RB set内的资源相比，如果相邻的RB set以及它们之间的保护带都可以使用，则可以达到更高的资源利用率。然而，当UE使用一个RB set时，相邻的RB set可能被其他设备占用，尤其是可能被其它异系统的设备占用，为了避免相邻RB set之间产生干扰，所以通常不使用保护带。因此如何将保护带利用起来是目前亟需解决的问题。
另外，在有占用信道带宽(Occupied Channel Bandwidth，OCB)要求的地区，为满足OCB要求，通常用户设备(User Equipment，UE)占用的RB在频域上是离散分布的，这些特征使得授权频段上频域连续的子信道难以应用到非授权频段。因此，如何支持频域离散的子信道也是有待进一步解决的问题。
本申请提供的子信道的配置方法可以应用于基于多类无线通信技术的SL通信系统，例如基于长期演进(long term evolution，LTE)技术、第四代移动通信技术(4th-generation，4G)、第五代移动通信技术(5th-generation，5G)、LTE与5G混合技术、5G新无线电(New Radio，NR)技术、以及未来通信发展中出现的新的通信技术，如第六代移动通信技术(6th-generation，6G)等的SL通信系统。
在本申请实施例中，提供一种子信道的配置方法、通信节点及存储介质，能够在非授权频段上配置SL资源，提高资源利用率。
首先，对本申请下述实施例涉及的概念进行解释：
在本申请实施例中，非授权频谱的新无线电(New Radio in Unlicensed Spectrum，NR-U)系统定义了RB的多个交织，每个交织由等间隔的公共资源块(Common Resource Block，CRB)构成。例如，交织m∈{0,1,…,M-1}由CRB{m,M+m,2M+m,3M+m,…}组成，M为交织的数目。通常，对于15kHz和30kHz的子载波间隔，交织的数目M分别为10和5。当然，本申请也包含其他的子载波间隔(例如，60kHz，120kHz，240kHz等)对应的交织，也不限制不同子载波对应的交织的数目M。BWP i内交织m中交织资源块(Interlaced Resource Block，IRB)(即BWP i内交织m中CRB的编号) 与公共资源块之间的关系如下：
其中，是BWP i相对于公共资源块0的起始公共资源块，μ为子载波间隔索引。示例性的，图1示出了一实施例提供的一种交织数目为5的交织示意图。如图1所示，交织0由CRB{0,5,10，…}组成，交织1由CRB{1,6,11，…}组成，以此类推，交织4由CRB{4,9,14，…}组成。在起始CRB为CRB 4且大小为106个CRB的BWP内，交织0中交织资源块{0,1,...,20}对应的CRB索引为{5,10,...,105}，交织1中交织资源块{0,1,...,20}对应的CRB索引为{6,11,...,106}，以此类推，交织4中交织资源块{0,1,2,...,21}对应的CRB索引为{4,9,14,...,109}。
在本申请实施例中，对于特定子载波间隔的一个载波，UE可以被配置N-1个保护带(Guard Band，GB)，每个GB通过起始CRB和CRB数目(即保护带的大小)来定义，N-1个GB将载波划分成N个RB set。对于一个载波，BWP包含整数个资源块集合，BWP的起始资源块且BWP的带宽其中，为资源块集合s0的起始RB，为资源块集合s1的结束RB，0≤s0≤s1≤N-1。即BWP的起始RB与资源块集合s0的起始RB对齐，BWP的结束RB与资源块集合s1的结束RB对齐。示例性的，图2示出了一实施例提供的一种载波、BWP与RB set的示意图。如图2所示，BWP的起始RB与RB set1的起始RB对齐，BWP的结束RB与RB set2的结束RB对齐，也就是说BWP由RB set 1、GB1和RB set2组成。在本申请实施例中，可以通过指示交织索引和RB set索引来指示分配给UE的BWP内的资源，交织与RB set(包括分配的相邻的RB set之间的保护带)的交集就是分配给UE的资源。资源分配中，RB set索引在BWP内从0到升序编号，为BWP内的RB set数目。一般地，基于载波配置BWP，在BWP内配置资源池，本申请也不排除基于载波配置资源池。
下面，对子信道的配置方法，通信节点及其技术效果进行描述。
图3示出了一实施例提供的一种子信道的配置方法的流程示意图，如图3所示，本实施例提供的方法适用于通信节点，该方法包括如下步骤。
S110、确定配置信息，配置信息包括资源池的子带和资源池的交织，或者包括资源池的资源块集合RB set、资源池的交织和频域单元大小。
S120、根据配置信息，确定频域单元。
S130、根据频域单元，配置子信道，每个子信道包括特定数量的频域单元，特定数量通过配置、预配置或者预定义的方式确定。
根据上述步骤S110可知，配置信息具体可以分为两种情况：一种情况是配置信息包括资源池的子带和资源池的交织；另一种情况是配置信息包括资源池的RB set、资源池的交织和频域单元大小。相应地，在步骤S120中，无论配置信息属于哪一种情况，都可以确定出频域单元，但是两种情况确定频域单元的方法不同。为了便于理解，下述实施例分别对上述两种情况进行详细描述。
另外，如无特别说明，本申请下述实施例中L、R、频率位置、频域单元大小、子带大小、子带数目等参数可以是通过配置、预配置或者预定义方式确定的，例如，特别说明可以是通过计算得到，或者通过预定义规则得到。
在一种可能的实现方式中，配置信息包括资源池的子带和资源池的交织。图4示出了一实施例提供的另一种子信道的配置方法的流程示意图，如图4所示，该方法包括如下步骤。
S210、确定配置信息，配置信息包括资源池的子带和资源池的交织。
在一实施例中，资源池包括至少一个子带，每个子带包括如下至少之一：RB set、RB set和与RB set相邻的保护带、一组连续的RB。
在一实施例中，子带基于资源池确定；或者，子带基于载波确定，基于载波的子带确定BWP的子带，基于BWP的子带确定资源池的子带；或者，子带基于BWP确定，基于BWP的子带确定资源池的子带；或者，子带基于载波确定，基于载波的子带确定资源池的子带。
配置、预配置或者预定义的资源池包含的交织(即哪些交织被分配给资源池)，资源池包含的交织与资源池包含的子带取交集就得到配置或者分配给资源池的频域资源。一般地，可以默认资源池包含所有交织。示例性的，基于资源池配置子带，并配置资源池包含的交织，从而确定资源池包含的频域资源，如图5所示，配置资源池包含子带0和1，以及配置资源池包含交织2和3，则图5中阴影部分所示的资源为资源池中的资源，即资源池的频域资源为子带0和1内交织2和3包含的所有RB。又示例性的，基于载波或者BWP配置子带，然后将部分或全部子带配置给资源池，如图6所示，一个子载波间隔为30kHz的载波或者BWP，共包含3个子带，假设交织总数为5，可以配置资源池包含子带0和1，并配置资源池包含交织2和3，则图6中阴影部分所示的资源为资源池中的资源。
在一实施例中，确定子带的规则包括下述7种中的至少之一：
规则1：保护带和与保护带相邻的索引小的RB set组成一个子带；
规则2：保护带和与保护带相邻的索引大的RB set组成一个子带；
规则3：保护带中前L个RB和与保护带相邻的索引小的RB set组成一个子带，L为大于或者等于0、且小于保护带包括的RB数量的整数；
规则4：保护带中后R个RB和与保护带相邻的索引大的RB set组成一个子带，R为大于或者等于0、且小于保护带包括的RB数量的整数；
规则5：K-1个频率位置确定K个子带，K为正整数；
规则6：根据子带大小和子带数目中的至少之一确定子带；
规则7：每个RB set为一个子带。
在一实施例中，可以通过配置、预配置或者预定义的方式确定采用哪个或者哪些规则来确定子带。
通常，资源块集合是从低频到高频进行编号的，即索引小的资源块集合就是频率低的资源块集合，索引大的资源块集合就是频率高的资源块集合，本申请不做严格区分。另外，保护带也是从低频到高频进行编号的。
示例一：保护带和与保护带相邻的索引小的RB set(或频率低的RB set)组成一个子带。
保护带和与保护带相邻的索引小的RB set组成一个子带，最后一个RB set(即资源池内索引最大的RB set)作为一个子带。
图7示出了一实施例提供的一种根据规则1确定子带的示意图。如图7所示，资源池包含3个保护带和4个RB set，保护带为图7中阴影标注的部分，RB在资源池内的编号为0,1,…,216。子带0的起止RB分别为0和55，即由资源池内的第一个RB set和第一个保护带组成；子带1的起止RB分别为56和110，即由资源池内的第二个RB set和第二个保护带组成；子带2的起止RB分别为111和166，即由资源池内的第三个RB set和第三个保护带组成；子带3的起止RB分别为167和216，即由资源池内的第四个RB set组成。
示例二：保护带和与保护带相邻的索引大的RB set(或频率高的RB set)组成一个子带。
保护带和与保护带相邻的索引大的RB set组成一个子带，第一个RB set(即资源池内索引最小的RB set)作为一个子带。
图8示出了一实施例提供的一种根据规则2确定子带的示意图。如图8所示，资源池包含3个保护带和4个RB set，保护带为图8中阴影标注的部分，RB在资源池内的编号为0,1,…,216。子带0的起止RB分别为0和49，即由资源池内的第一个RB set组成；子带1的起止RB分别为50和105，即由资源池内的第一个保护带和第二个RB set组成；子带2的起止RB分别为106和160， 即由资源池内的第二个保护带和第三个RB set组成；子带3的起止RB分别为161和216，即由资源池内的第三个保护带和第四个RB set组成。
示例三：保护带中前L个RB和与保护带相邻的索引小的RB set组成一个子带，L为大于或者等于0、且小于保护带包括的RB数量的整数。
对于一个资源池，一个保护带中前L个RB和与保护带相邻的索引小的RB set组成一个子带，最后一个RB set作为一个子带，L为大于或者等于0、且小于保护带包括的RB数量的整数。资源池内的每个保护带可以分别对应一个L值，或者，资源池内的所有保护带对应一个L值。
图9示出了一实施例提供的一种根据规则3确定子带的示意图。如图9所示，资源池包含2个保护带和3个RB set，L的取值为5，第一个保护带的前5个RB和第一个RB set组成一个子带；第二个保护带的前5个BR和第二个RB set组成一个子带；第三个RB set作为一个子带。
在一实施例中，对于规则3，L的取值通过配置、预配置或者预定义的方式确定；或者，L的取值根据频域单元大小计算得到。
对于L的取值根据频域单元大小计算得到的情况，每个频域单元为在一个子带内一个交织包括的所有RB。例如，频域单元大小为个RB，则L的取值需要满足条件：使得相邻的索引小的RB set与保护带的前L个RB组成的子带中资源池对应的交织包含的RB数均为的最小(或者最大)的值。即，L使得资源池的每个子带和资源池的每个交织的交集包含的RB数等于配置、预配置或者预定义的频域单元大小。如图10所示，假设资源池包含的交织为交织0、交织1和交织2(可以配置、预配置或者预定义资源池包含哪些交织，或者默认资源池包含所有交织)，保护带GB0包含6个RB，与GB0相邻的索引小的资源集合RB set0包含8个RB，在RB set0内交织0、1和2对应的RB数分别为1、1和2，假设频域单元大小为2个RB，即则使得RB set0和GB0的前L个RB组成的子带满足该子带内交织0、1和2包含的RB数(即对应的频域单元大小)均为2的最小的L是2，即L＝2。
示例四：保护带中后R个RB和与保护带相邻的索引大的RB set组成一个子带，R为大于或者等于0、且小于保护带包括的RB数量的整数。
对于一个资源池，一个保护带中后R个RB和与保护带相邻的索引大的RB set组成一个子带，第一个RB set作为一个子带，R为大于或者等于0、且小于保护带包括的RB数量的整数。资源池内的每个保护带可以分别对应一个R值，或者，资源池内的所有保护带对应一个R值。
在一实施例中，对于规则4，R的取值通过配置、预配置或者预定义的方式确定；或者，R的取值根据频域单元大小计算得到。
对于R的取值根据频域单元大小计算得到的情况，其计算方法与上述示例三中根据频域单元大小计算L的取值的方法类似，为了简洁，此处不再赘述。
示例五：保护带中前L个RB和与保护带相邻的索引小的RB set组成一个子带，保护带中后R个RB和与保护带相邻的索引大的RB set组成一个子带，对于两侧都有保护带的RB set，该RB set与索引小的保护带的后R个RB、索引大的保护带的前L个RB组成一个子带，L为大于或者等于0、且小于保护带包括的RB数量的整数，R为大于或者等于0、且小于保护带包括的RB数量的整数。
对于一个资源池，一个保护带中前L个RB和与保护带相邻的索引小的RB set组成一个子带，保护带中后R个RB和与保护带相邻的索引大的RB set组成一个子带，对于一个保护带，L与R之和是小于或者等于保护带包括的RB数量的整数。资源池内的每个保护带可以分别对应一个L值，或者，资源池内的所有保护带对应一个L值；资源池内的每个保护带可以分别对应一个R值，或者，资源池内的所有保护带对应一个R值。
图11示出了一实施例提供的一种根据规则3和规则4确定子带的示意图。如图11所示，资源池包含2个保护带和3个RB set，第一个保护带的前3个RB和第一个RB set组成一个子带(即子带0)；第一个保护带的后2个RB、第二个RB set以及第二个保护带的前2个RB组成一个子带(即子带1)；第二个保护带的后4个RB和第三个RB set组成一个子带(即子带2)。
示例六：K-1个频率位置确定K个子带，K为正整数。
K-1个频率位置将资源池划分成K的子带，记为子带k，k＝0,1,…,K-1，子带k(0＜k≤K-1)的起始RB为频率位置k-1对应的RB，子带k(0≤k＜K-1)的结束RB为频率位置k对应的RB的前一个RB，子带0的起始RB为资源池的第一个RB，子带K-1的结束RB为资源池的最后一个RB。
图12示出了一实施例提供的一种根据规则5确定子带的示意图。如图12所示，RB在资源池内的编号(即RB索引)为0,1,…,159，两个频率位置分别为RB 55和RB 110，子带0的起止RB分别为0(即资源池的第一个RB)和54(即频率位置0对应的RB的前一个RB)，子带1的起止RB分别为55(即频率位置0对应的RB)和109(即频率位置1对应的RB的前一个RB)，子带2的起止RB分别为110(即频率位置1对应的RB)和159(即资源池的最后一个RB)。
上述方法将频率位置对应的RB作为索引高的子带的起始RB，也可以将频率位置对应的RB作为索引低的子带的结束RB，即：
K-1个频率位置将资源池划分成K的子带，记为子带k，k＝0,1,…,K-1，子 带k(0＜k≤K-1)的起始RB为频率位置k-1对应的RB的后一个RB，子带k(0≤k＜K-1)的结束RB为频率位置k对应的RB，子带0的起始RB为资源池的第一个RB，子带K-1的结束RB为资源池的最后一个RB。
图13示出了一实施例提供的另一种根据规则5确定子带的示意图。如图13所示，RB在资源池内的编号(即RB索引)为0,1,…,159，两个频率位置分别为RB 55和RB 110，子带0的起止RB分别为0(即资源池的第一个RB)和55(即频率位置0对应的RB)，子带1的起止RB分别为56(即频率位置0对应的RB的后一个RB)和110(即频率位置1对应的RB)，子带2的起止RB分别为111(即频率位置1对应的RB的后一个RB)和159(即资源池的最后一个RB)。
在一实施例中，K-1个频率位置通过配置、预配置或者预定义的方式确定。
示例七：根据子带大小和子带数目中的至少之一确定子带。
方式1、根据子带大小和子带数目K，从资源池的第一个RB开始每个RB为一个子带，资源池内包括K个子带；或者，如果配置或者预配置了资源池大小(即资源池包含的RB数目)，根据子带大小和子带数目K，从资源池的第一个RB开始每个RB为一个子带，资源池内包括K个子带，其中，小于或者等于
图14示出了一实施例提供的一种根据规则6确定子带的示意图。K＝3，资源池包含3个子带，每个子带大小为50个RB，由于资源池包含的RB数不是子带大小的整数倍，剩余的2个RB不属于任何一个子带。
方式2、根据资源池的大小和子带大小确定子带数目，进而确定资源池的子带。
具体的，确定子带大小和资源池的大小根据资源池的大小和子带大小确定子带数目或者
可选地，如果则子带数目如果则子带数目其中，Th为门限值，每个资源池或者每个BWP或者每个载波对应一个门限值。表示对x向下取整，表示对x向上取整。也可以配置或者预配置或者预定义的方式确定子带数目是还是子带数目是
当子带数目时，除最后一个子带外在资源池中从第一个RB开始每个RB为一个子带，最后一个子带的大小为 个RB，其中，mod为求余运算。图15示出了一实施例提供的另一种根据规则6确定子带的示意图，如图15所示， 则资源池包含3个子带，前2个子带大小为50个RB，最后一个子带大小为50+152mod50＝52个RB。即资源池包含的RB数不是子带大小的整数倍时，剩余的个RB属于最后一个子带。
当子带数目时，除最后一个子带外在资源池中从第一个RB开始每个RB为一个子带，最后一个子带的大小为个RB。即资源池包含的RB数不是子带大小的整数倍时，剩余的个RB作为一个子带。
方式3、根据资源池的大小和子带数目确定子带大小，进而确定资源池的子带。
具体的，确定子带的数目K和资源池的大小根据资源池的大小和子带数目K确定子带大小，前个子带的大小为个RB，后个子带的大小为个RB，这些子带在资源池中从第一个RB开始依次摆放。图16示出了一实施例提供的又一种根据规则6确定子带的示意图，如图16所示，K＝3，前152 mod 3＝2个子带的大小为个RB，最后3-152 mod 3＝1个子带的大小为个RB。
或者，确定子带的数目K和资源池的大小根据资源池的大小和子带数目K确定子带大小，前个子带的大小为个RB，后个子带的大小为个RB，这些子带在资源池中从第一个RB开始依次摆放。
或者，确定子带的数目K和资源池的大小根据资源池的大小和子带数目K确定子带大小，在资源池中从第一个RB开始每个RB为一个子带。
或者，确定子带的数目K和资源池的大小根据资源池的大小和子带数目K确定子带大小，对于前K-1个子带，在资源池中从第一个RB开始每个RB为一个子带，资源池的最后个RB为第K个子带。
或者，确定子带的数目K和资源池的大小根据资源池的大小和子带数目K确定子带大小，资源池的前个RB为第一个子带，对于第二至第K个子带，在资源池中从第个RB开始每个RB为一个子带。
示例八：每个RB set为一个子带。
图17示出了一实施例提供的一种根据规则7确定子带的示意图，资源池包 含3个保护带和4个RB set，RB set0、RB set1、RB set2和RB set3分别对应子带0、子带1、子带2和子带3，即每个RB set对应一个子带。
在上述所有示例中，如果资源池仅包含一个资源块集合，则该资源块集合对应一个子带。
需要说明的是，上述规则的示例给出了基于资源池确定子带的方法，类似地，也可以基于载波或者BWP确定子带，只需将“资源池”替换为“载波或者BWP”即可，如果基于载波或者BWP确定子带，则需要进一步配置资源池包含哪些子带，或者哪些子带属于资源池。一般地，一个载波中配置至少一个BWP，一个BWP中配置至少一个资源池，所以，通常资源池包含的子带是BWP包含的子带的子集，BWP包含的子带是载波包含的子带的子集，但也不排除其他情况，例如，直接配置载波中哪些子带属于资源池，即直接基于载波包含的子带配置资源池包含的子带。
在本申请中，配置或者预配置某个信息可以为：由网络或基站将信息配置给UE；或者，由其他高层实体(如UE自身的高层、其他网络实体等)为UE提供信息。
本申请提供的方法可以通过配置或者预配置方式使能或者去使能，或者通过使能SL信道或信号使用交织进行使能，其中，使能表示能采用本申请中的方法，去使能表示不能采用本申请中的方法(即采用NR R16SL或者NR R17SL中资源池的配置方法)。通过是否使能本申请中的方法，可以支持在有OCB要求的地区和无OCB要求的地区灵活实现SL通信。
通常，可以配置或者预配置一个或多个RB set(也可能包含资源块集合之间的保护带)属于资源池，配置、预配置或者预定义一个或多个交织属于资源池，或者默认资源池包含所有交织，进一步配置资源池包含的子信道，以便在资源池中基于子信道分配SL传输资源。也可以配置或者预配置资源池的起始RB和资源池包含的连续RB数(UE期望资源池的起始RB与RB set sx的起始RB对齐，资源池的结束RB与RB set sy的结束RB对齐，其中，0≤sx≤sy≤N-1，N为载波或者BWP包含RB set的总数)，配置、预配置或者预定义一个资源池包含的交织，或者默认资源池包含所有交织，然后进一步配置资源池包含的子信道。
S220、根据资源池的子带和资源池的交织，确定频域单元，每个频域单元为在一个子带内一个交织包括的所有RB。
每个频域单元为在一个子带内一个交织包括的所有RB，即频域单元为一个子带中的资源块和一个交织中的资源块的交集。
在一实施例中，频域单元按照先交织后子带的规则进行编号；或者，频域单元按照先子带后交织的规则进行编号。
例如，按照先交织后子带的规则对频域单元编号，包括：先按照交织索引升序对第一个子带内的频域单元编号，然后按照交织索引升序对第二个子带内的频域单元编号，按照子带索引升序以此类推，直至对所有子带内的频域单元完成编号。具体地，假设资源池包含K个子带和M个交织，第一个子带内按照交织索引升序对频域单元依次编号为0,1,...,M-1，第二个子带内按照交织索引升序对频域单元编号为M,M+1,...,2M-1，以此类推，第K个子带内按照交织索引升序对频域单元编号为(K-1)M,(K-1)M+1,...,KM-1。
又比如，按照先交织后子带的规则对频域单元编号，包括：先按照交织索引升序对第一个子带内的频域单元编号，然后按照交织索引降序对第二个子带内的频域单元编号，按照子带索引升序以此类推，对于索引为偶数的子带，按照交织索引升序对该子带内的频域单元编号，对于索引为奇数的子带，按照交织索引降序对该子带内的频域单元编号，直至对所有子带内的频域单元完成编号。具体地，假设资源池包含K个子带和M个交织，第一个子带内按照交织索引升序对频域单元依次编号为0,1,...,M-1，第二个子带内按照交织索引降序对频域单元编号为M,M+1,...,2M-1，以此类推，第2k-1个子带内按照交织索引升序对频域单元依次编号为(2k-2)M,(2k-2)M+1,...,(2k-1)M-1。第2k个子带内按照交织索引降序对频域单元依次编号为(2k-1)M,(2k-1)M+1,...,2kM-1。类似地，也可以将本例子中的升序和降序交换一下，即先按照交织索引降序对第一个子带内的频域单元编号，然后按照交织索引升序对第二个子带内的频域单元编号，按照子带索引升序以此类推，对于索引为偶数的子带，按照交织索引降序对该子带内的频域单元编号，对于索引为奇数的子带，按照交织索引升序对该子带内的频域单元编号，直至对所有子带内的频域单元完成编号。采用该方式对频域单元编号可以使得连续的频域单元对应的交织索引不会跳变。
例如，按照先子带后交织的规则对频域单元编号，包括：先按照子带索引升序对第一个交织内的频域单元编号，然后按照子带索引升序对第二个交织内的频域单元编号，按照交织索引升序以此类推，直至对所有交织内的频域单元完成编号。具体地，假设资源池包含K个子带和M个交织，则第一个交织内按照子带索引升序对频域单元依次编号为0,1,...,K-1，第二个交织内按照子带索引升序对频域单元依次为K,K+1,...,2K-1，以此类推，第M个交织内按照子带索引升序对频域单元依次编号为(M-1)K,(M-1)K+1,...,MK-1。

S230、根据频域单元，配置子信道，每个子信道包括特定数量的频域单元，特定数量通过配置、预配置或者预定义的方式确定。
例如，对于资源池内进行编号后的频域单元，从第一个频域单元开始，每X个频域单元为一个子信道，X通过配置、预配置或者预定义的方式确定。
S240、基于子信道为物理边链路共享信道(Physical Sidelink Shared Channel，PSSCH)分配频域资源，PSSCH的频域资源包括至少一个子信道。
在一实施例中，若PSSCH的频域资源中没有子信道跨RB set，则PSSCH只能使用被分配的子信道中不属于保护带的RB，或者PSSCH不能使用被分配的子信道中属于保护带的RB；
若PSSCH的频域资源中所有子信道的并集跨多个RB set，则PSSCH使用PSSCH的频域资源中所有子信道的并集所跨的RB set中的RB和所有子信道的并集所跨的RB set之间的保护带中的RB。
在一实施例中，每个PSSCH传输与一个物理边链路控制信道(Physical Sidelink Control Channel，PSCCH)传输关联；
PSCCH的频域资源为从关联的PSSCH的第一个子信道的第一个不属于保护带的RB开始的个RB、且PSCCH的频域资源位于一个子信道内；或者，
PSCCH的频域资源为从关联的PSSCH的第一个子信道的第一个不属于保护带的RB开始的个不属于保护带的RB；或者，
若PSCCH关联的PSSCH的第一个子信道没有跨RB set(即子信道只包含了一个RB set中的RB)，则PSCCH的频域资源为从关联的PSSCH的第一个子信道的第一个不属于保护带的RB开始的个不属于保护带的RB、且PSCCH的频域资源位于一个子信道内；若PSCCH关联的PSSCH的第一个子信道跨多个RB set(即子信道包含了多个RB set中的RB)，则PSCCH的频域资源为从关联的PSSCH的第一个子信道的第一个不属于保护带的RB开始的个RB、且PSCCH的频域资源位于一个子信道内，用于PSCCH传输的个RB仅包含子信道所跨的RB set中的RB和子信道所跨的RB set之间的保护带中的RB。
在一实施例中，对于每个资源池，UE被配置或者预配置PSCCH占用的RB数目
在另一种可能的实现方式中，配置信息包括资源池的RB set、资源池的交织和频域单元大小。图18示出了一实施例提供的又一种子信道的配置方法的流程示意图，如图18所示，该方法包括如下步骤。
S310、确定配置信息，配置信息包括资源池的RB set、资源池的交织和频域单元大小。
S320、根据资源池的RB set、资源池的交织和频域单元大小，确定频域单元，每个频域单元为从资源池的一个RB set的起始RB开始的包含在一个交织内的频域单元大小个RB。
假设频域单元大小为则从资源池的一个RB set的起始RB开始的包含在一个交织内的个RB为一个频域单元。
在一实施例中，频域单元按照先交织后RB set的规则进行编号；或者，频域单元按照先RB set后交织的规则进行编号。
例如，按照先交织后RB set对频域单元编号，包括：先按照交织索引升序对第一个RB set对应的频域单元编号，然后按照交织索引升序对第二个RB set对应的频域单元编号，按照RB set索引升序以此类推，直至对资源池内的所有RB set对应的频域单元完成编号。
又比如，按照先交织后RB set对频域单元编号，包括：先按照交织索引升序对第一个RB set对应的频域单元编号，然后按照交织索引降序对第二个RB set对应的频域单元编号，按照RB set索引升序以此类推，对于索引为偶数的RB set，按照交织索引升序对该RB set对应的频域单元编号，对于索引为奇数的RB set，按照交织索引降序对该RB set对应的频域单元编号，直至对资源池内的所有RB set对应的频域单元完成编号。类似地，也可以将本例子中的升序和降序交换一 下，即先按照交织索引降序对第一个RB set对应的频域单元编号，然后按照交织索引升序对第二个RB set对应的频域单元编号，按照RB set索引升序以此类推，对于索引为偶数的RB set，按照交织索引降序对该RB set对应的频域单元编号，对于索引为奇数的RB set，按照交织索引升序对该RB set对应的频域单元编号，直至对资源池内的所有RB set对应的频域单元完成编号。采用该方式对频域单元编号可以使得连续的频域单元对应的交织索引不会跳变。
例如，按照先RB set后交织对频域单元编号，包括：先按照RB set索引升序对第一个交织内的频域单元编号，然后按照RB set索引升序对第二个交织内的频域单元编号，按照交织索引升序以此类推，直至对资源池内的所有交织内的频域单元完成编号。
又比如，按照先RB set后交织对频域单元编号，包括：先按照RB set索引升序对第一个交织内的频域单元编号，然后按照RB set索引降序对第二个交织内的频域单元编号，按照交织索引升序以此类推，对于索引为偶数的交织，按照RB set索引升序对该交织内的频域单元编号，对于索引为奇数的交织，按照RB set索引降序对该交织内的频域单元编号，直至对所有交织内的频域单元完成编号。类似地，也可以将本例子中的升序和降序交换一下，即先按照RB set索引降序对第一个交织内的频域单元编号，然后按照RB set索引升序对第二个交织内的频域单元编号，按照交织索引升序以此类推，对于索引为偶数的交织，按照RB set索引降序对该交织内的频域单元编号，对于索引为奇数的交织，按照RB set索引升序对该交织内的频域单元编号，直至对所有交织内的频域单元完成编号。采用该方式对频域单元编号可以使得连续的频域单元对应的RB set索引不会跳变。
上述举例与步骤S220中“频域单元按照先交织后子带的规则进行编号；或者，频域单元按照先子带后交织的规则进行编号”的具体实例类似，只需将“子带”改为“RB set”，将“子带内的频域单元”改为“RB set对应的频域单元”即可，修改的目的是和本实施例中的方法描述更匹配，具体实例没有本质上的区别，为了简洁，此处不再赘述。
在一实施例中，UE期望一个频域单元包含在一个RB set内；或者，
UE期望一个频域单元包含在一个RB set内或者包含在一个RB set以及相邻的保护带内；或者，
UE不期望一个频域单元跨多个RB set；或者，
当资源池仅包含一个RB set时UE期望资源池的所有频域单元包含在一个RB set内，当资源池包含多个RB set时，UE不期望一个频域单元跨多个RB set； 或者，
当资源池仅包含一个RB set时UE期望资源池的所有频域单元包含在一个RB set内，当资源池包含多个RB set时，对于资源池内的最后一个RB set，UE期望一个频域单元包含在一个RB set内，或者频域单元仅仅保留RB set内的RB(即允许频域单元小于个RB)，对于资源池的其他RB set，UE不期望一个频域单元跨多个RB set。
S330、根据频域单元，配置子信道，每个子信道包括特定数量的频域单元，特定数量通过配置、预配置或者预定义的方式确定。
例如，对于资源池内编号后的频域单元，从第一个频域单元开始，每X个频域单元为一个子信道，X的通过配置、预配置或者预定义的方式确定。
S340、基于子信道为物理边链路共享信道PSSCH分配频域资源，PSSCH的频域资源包括至少一个子信道。
在一实施例中，若PSSCH的频域资源中没有子信道跨RB set，则PSSCH只能使用被分配的子信道中不属于保护带的RB，或者PSSCH不能使用被分配的子信道中属于保护带的RB；
若PSSCH的频域资源中所有子信道的并集跨多个RB set，则PSSCH使用PSSCH的频域资源中所有子信道的并集所跨的RB set中的RB和所有子信道的并集所跨的RB set之间的保护带中的RB。
在一实施例中，每个PSSCH传输与一个物理边链路控制信道PSCCH传输关联；
PSCCH的频域资源为从关联的PSSCH的第一个子信道的第一个不属于保护带的RB开始的个RB、且PSCCH的频域资源位于一个子信道内；或者，
