Description

子信道的确定方法、通信节点及存储介质 技术领域
本申请涉及通信技术领域，例如涉及子信道的确定方法、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，一个载波配置一个SL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一个或者多个资源块集合(Resource Block set，RB set)。当资源池包含多个RB set时，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。但是，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。而SL通常基于子信道进行资源分配或者资源选择。

具体实施方式
此处所描述的实施例仅仅用以解释本申请。下文中将结合附图对本申请的实施例进行说明。
SL通信包括车辆对车辆(vehicle-to-vehicle，V2V)通信、车辆对任何东西(vehicle-to-anything，V2X)通信、用户设备(User Equipment，UE)与UE直接通信(Device to Device，D2D)等。对于SL通信，当UE之间有业务需要传输时，业务数据可以不经过其他网络设备的转发，而是由数据源设备直接传输给目标设备，即实现了设备间的直接通信。
SL通信可以工作在授权频段、智能交通系统(Intelligent Traffic Systems，ITS)频段等。在将来，也可以工作在非授权频谱。当SL UE被配置至少一个资源池时，资源池定义了在一个载波的BWP内用于SL通信的时频资源(SL工作在授权频段时，通常边链路同步信号块(sidelink-Synchronization Signal/Physical broadcast channel Block，S-SSB)资源不包含在SL资源池中；但SL工作在非授权频段时，S-SSB资源可能不包含在SL资源池中，也可能包含在SL资源池中)。在时域上，资源池由一组具有特定周期的时隙组成。在频域上，资源池由至少一个连续子信道组成，子信道包括多个连续的资源块(Resource Block，RB)，子信道大小可配置。通常，在频域上，资源分配的粒度是子信道，每个SL传输占用一个或者多个连续的子信道。
对于非授权频段上的SL通信，当资源池包含多个RB set时，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。但是，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，如何确定资源池内包括的子信道是亟需解决的问题。
本申请提供的子信道的确定方法可以应用于基于各类无线通信技术的SL通信系统，例如基于长期演进技术(Long Term Evolution，LTE)技术、4G技术、5G技术、LTE与5G混合技术、5G新无线(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，提供子信道的确定方法、通信节点及存储介质，能够确定资源池包括的子信道，提高资源利用率。
下面，对子信道的确定方法，通信节点及其技术效果进行描述。
图1示出了一实施例提供的一种子信道的确定方法的流程示意图，如图1所示，本实施例提供的方法适用于通信节点，该方法包括S110-S120。
S110、确定配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小、子信道数量中的至少之一。
在一实施例中，配置信息可以为资源池中每个资源块集合RB set对应的子信道的配置信息，也可以为资源池对应的子信道的配置信息。即子信道可以按照RB set进行划分，也可以按照资源池进行划分。
配置信息包括第一个子信道的起始资源块位置、子信道大小、子信道数量中的至少之一。即配置信息可以包括：1.第一个子信道的起始资源块位置；2.子信道大小；3.子信道数量；4.第一个子信道的起始资源块位置和子信道大小；5.第一个子信道的起始资源块位置和子信道数量；6.子信道大小和子信道数量；7.第一个子信道的起始资源块位置、子信道大小和子信道数量。共7种情况。
对于配置信息不包括第一个子信道的起始资源块位置的情况，如上述情况2、3、6，通信节点可以预定义每个RB set或者资源池对应的第一个子信道的起始资源块位置，例如，每个RB set/资源池对应的第一个子信道的起始资源块位置为该RB set/资源池的起始资源块位置。对于配置信息不包括子信道大小的情况，如上述情况1、3、5，通信节点可以提前配置有默认的子信道大小。对于配置信息不包括子信道数量的情况，如上述情况1、2、4，通信节点可以提前配置有默认子信道数量；或者，通信节点根据每个RB set/资源池的大小、第一个子信道的起始资源块位置和子信道大小计算子信道数量，例如，当每个RB set/资源池对应的第一个子信道的起始资源块位置为该RB set/资源池的起始资源块位置时，该RB set/资源池对应的子信道数量为该RB set/资源池包含的资源块数量除以子信道大小，如果相除后的结果不是整数，可以对结果向下取整。
S120、根据预设规则和配置信息，确定资源池包括的子信道。
在一实施例中，预设规则可以包括第一预设子规则、第二预设子规则、第三预设子规则中的至少之一。
根据上述S110可知，配置信息可以为资源池中每个资源块集合RB set对应 的子信道的配置信息，也可以为资源池对应的子信道的配置信息。相应地，在S120中，无论配置信息属于哪一种情况，都可以根据相应的预设规则，确定资源池包括的子信道。为了便于理解，下述实施例分别对不同的情况进行详细描述。
另外，如无特别说明，本申请下述实施例中第一门限至第八门限中可以由高层实体配置，或者预定义。高层实体包括如下至少之一：网络、基站、通信节点(如UE)自己的高层、其他高层网络实体。“第一”、“第二”、…、“第八”等仅仅用于名义上区分不同门限，例如，实现时也不排除部分仅仅序数词不同的门限是相同的参数。例如，第三门限和第四门限是相同的参数，第五门限和第六门限是相同的参数。
在第一种实现方式中，配置信息为资源池中每个RB set对应的子信道的配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小和子信道数量中至少之一，预设规则包括第一预设子规则。
通信节点确定资源池包括的子信道的方法包括：对于资源池中的任一RB set，从RB set的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道；如果RB set有剩余资源块，则根据第一预设子规则确定剩余资源块所属的子信道；资源池包括的子信道由资源池中所有RB set对应的子信道组成。
在一实施例中，RB set的剩余资源块为从RB set的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道后，在RB set的结束位置剩余的资源块。
一种示例性的，第一预设子规则包括以下规则中的任意一项：
规则a1、剩余资源块作为一个子信道。
规则a2、剩余资源块不属于任何子信道。
规则a3、剩余资源块和RB set中按照子信道大小依次划分的子信道数量个子信道中的最后一个子信道合并成一个子信道。
规则a4、根据剩余资源块的数量和第一门限之间的大小关系、剩余资源块的数量与子信道大小的比值和第二门限之间的大小关系、剩余资源块后面是否有保护带中的至少之一，确定剩余资源块所属的子信道。
对于规则a4，包括如下至少之一：

本申请中上述规则在不冲突的情况下，可以任意组合，本申请实施例对此不作限制。
例如，对于资源池的第i个RB set，子信道由nsubCHsize个连续资源块组成，物理资源块的编号j＝0,1,,nsubCHsize-1。
nsubCHsize是子信道大小，通常，对于一个资源池中的所有RB set，子信道大小是相同的，也就是说子信道大小一般是按照资源池配置的，以使得一个资源池中子信道大小一致，本申请也不排除不同RB set配置不同的子信道大小的情况。
是资源池内资源块集合i的第一个子信道的第一个RB索引，用于指示资源池内资源块集合i的第一个子信道的第一个RB的位置，上述公式中该参数是相对该资源池所在的SL BWP的最低RB索引的索引。对于资源池中的每个RB set，高层实体可以为通信节点配置资源块集合的第一个子信道的第一个RB的位置；或者，预定义资源块集合的第一个子信道的第一个RB与该资源块集合的最低RB对齐，即资源块集合的第一个子信道的第一个RB就是资源块集合的最低RB。对于一个RB set，如果高层实体没有为通信节点配置该资源块集合的第一个子信道的第一个RB的位置，则通信节点默认该资源块集合的第一个子信道的第一个RB与该资源块集合的最低RB对齐。
是资源块集合i对应的子信道数量，对资源块集合i，从其第一个子 信道的起始资源块位置开始按照子信道大小依次划分个连续且不交叠的子信道。一个资源块集合对应的子信道数量可以由高层实体提供给通信节点，例如，高层实体可以为资源池中每个RB set单独配置子信道数量；或者，对于一个资源池，配置一个子信道数量，该子信道数量应用于资源池中的每个RB set，即资源池中每个RB set对应的子信道数量是相同的，均等于为高层实体配置的子信道数量；或者，高层实体为资源池配置总的子信道数量T，资源池中每个RB set对应的子信道数量相同，等于T除以资源池中RB set的总数，如果不能整除则向下取整；或者，通信节点根据RB set包含的资源块数量和子信道大小获取该RB set对应的子信道数量；或者，通信节点根据RB set包含的资源块数量、资源块集合的第一个子信道的第一个RB的位置和子信道大小获取该RB set对应的子信道数量。
资源块集合i对应的子信道的总数未必等于例如，可以等于或者等于例如，一个RB set包含50个RB，子信道大小为15个RB，根据RB set包含的资源块数量50和子信道大小15获取该RB set对应的子信道数量，比如，子信道数量为50/15向下取整等于3，假设该RB set的第一个子信道的第一个RB与该RB set的最低RB对齐，因此，有3个大小为15个RB的子信道包含在该RB set中，对于剩余的50-15*3＝5个RB，可以按照第一预设子规则来确定其对应的子信道。如果剩余的RB不属于任何子信道，或者合并到该RB set的最后一个子信道中，则这种情况下该RB set对应的子信道的总数是3；如果剩余的RB作为一个子信道或者与相邻的保护带中的RB组成一个子信道，则该RB set对应的子信道的总数是4。
在本实施例中，一个RB set中的剩余资源块的数量可以小于子信道大小，也可以大于或者等于子信道大小；一个RB set按照子信道大小依次划分子信道后也可以不剩余资源块。
对于资源池中的一个RB set，从该RB set的第一个子信道的第一个RB位置开始按照子信道大小依次划分的子信道数量可以由高层实体配置。例如，一个RB set包含46个资源块，子信道大小为15个RB，该高层实体为通信节点配置该RB set对应的子信道数量为2，假设RB set的第一个子信道的第一个RB与该RB set的最低RB对齐，从RB set的第一个子信道的第一个RB位置开始按照子信道大小依次划分2个子信道，因此，该RB set的剩余RB的数量为46-15*2＝16，即该RB set中的剩余RB数大于子信道大小。
对于资源池中的一个RB set，从该RB set的第一个子信道的第一个RB位置开始按照子信道大小依次划分的子信道数量可以由通信节点计算得到。例如，一个RB set包含46个资源块，子信道大小为15个RB，假设RB set的第一个子信道的第一个RB与该RB set的最低RB对齐，则大小为15个RB的子信道 的数量为46/15向下取整，即子信道数量为3，因此，该RB set的剩余RB的数量为46-15*3＝1，即该RB set中的剩余RB数小于子信道大小。
再比如，一个RB set包含46个资源块，该RB set后面的保护带包含15个RB，子信道大小为15个RB，该RB set对应的子信道数量为4，假设RB set的第一个子信道的第一个RB与该RB set的最低RB对齐，则该RB set和该保护带被依次划分为4个子信道，前3个子信道在该RB set内，第四个子信道包含该RB set的最后一个RB和保护带的前14个RB。
在本实现方式中，配置信息中的子信道大小，或者上述“按照子信道大小依次划分子信道数量个连续且不交叠的子信道”中的子信道大小，为名义上的子信道大小，根据第一预设子规则确定的子信道大小可以与名义上的子信道大小不相等。
下面提供一些示例，用来解释说明“根据第一预设子规则确定RB set的剩余资源块所属的子信道”。
示例一
在示例一中，第一预设子规则采用上述规则a4-01，或者规则c1，或者规则d1和d7的组合。
图2示出了一实施例提供的一种采用规则a4-01，或者规则c1，或者规则d1和d7的组合确定剩余资源块所属的子信道的示意图。如图2所示，一个资源池包含两个RB set，即资源块集合0和资源块集合1，它们包含的RB数分别是47和45。资源块集合0和资源块集合1之间的保护带包含14个RB。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐，子信道大小为12个RB，第一门限为10，在按照子信道大小12个RB依次划分3个连续且不交叠的子信道后，资源块集合0的剩余RB数为11，大于第一门限10，因此作为一个子信道；资源块集合1的剩余RB的数量为9，小于第一门限，因此不属于任何子信道。故资源池包含的子信道一共是7个，其中，资源块集合0和1分别对应其中的前4个和后3个子信道，子信道大小依次为：12,12,12,11,12,12,12。
图3示出了一实施例提供的另一种采用规则a4-01，或者规则c1，或者规则d1和d7的组合确定剩余资源块所属的子信道的示意图。如图3所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2，相邻的两个RB set之间具有保护带。对于每个RB set，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐，第一门限为10。在按照子信道大小依次划分3个连续且不交叠的子信道后，资源块集合0的剩余RB数为1，小于 第一门限，因此剩余RB不属于任何子信道；资源块集合1的剩余RB数为10，等于第一门限，因此剩余RB作为一个子信道；资源块集合2的剩余RB数为10，等于第一门限，因此剩余RB作为一个子信道。故资源池包含的子信道一共是11个。
示例二
在示例二中，第一预设子规则采用上述规则a4-02，或者规则c2，或者规则d14和d20的组合。
图4示出了一实施例提供的一种采用规则a4-02，或者规则c2，或者规则d14和d20的组合确定剩余资源块所属的子信道的示意图。如图4所示，一个资源池包含两个RB set，即资源块集合0和资源块集合1，它们包含的RB数分别是47和45。资源块集合0和资源块集合1之间的保护带包含14个RB。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐，子信道大小为12个RB，第二门限为0.7，在按照子信道大小12个RB依次划分3个连续且不交叠的子信道后，资源块集合0的剩余RB数与子信道大小的比值为11/12＝0.92，大于第二门限0.7，因此作为一个子信道；资源块集合1的剩余RB数与子信道大小的比值为9/12＝0.75，大于第二门限0.7，因此也作为一个子信道；故资源池包含的子信道一共是8个，子信道大小依次为：12,12,12,11,12,12,12,9。
示例三
在示例三中，第一预设子规则采用上述规则a1或者规则c3。也就是说，对于一个RB set，不管剩余RB的数量是多少，都将剩余RB作为一个子信道。
图5示出了一实施例提供的一种采用规则a1或者规则c3确定剩余资源块所属的子信道的示意图。如图5所示，一个资源池包含两个RB set，即资源块集合0和资源块集合1。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后剩余的资源块作为一个子信道；对于资源块集合1，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的2个子信道后剩余的资源块作为一个子信道。故资源池包含的子信道一共是7个。
示例四
在示例四中，第一预设子规则采用上述规则a3或者规则c4。
图6示出了一实施例提供的一种采用规则a3或者规则c4确定剩余资源块所属的子信道的示意图。如图6所示，一个资源池包含两个RB set，即资源块集 合0和资源块集合1。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余的资源块合并到按照子信道大小划分的最后一个子信道中，即最后一个子信道的大小为配置的子信道大小和资源块集合的剩余资源块之和。类似地，资源块集合1的剩余的资源块也合并到从该资源块集合第一个子信道的第一个RB位置开始按照子信道大小划分的最后一个子信道中。因此，资源池包含的子信道一共是6个。
示例五
在示例五中，第一预设子规则采用上述规则a4-03或者规则d40和d41的组合。
图7示出了一实施例提供的一种采用规则a4-03或者规则d40和d41的组合确定剩余资源块所属的子信道的示意图。如图7所示，一个资源池包含两个RB set，即资源块集合0和资源块集合1，它们包含的RB数均为46。资源块集合0和资源块集合1之间的保护带包含14个RB。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐，子信道大小为12个RB，在按照子信道大小12个RB依次划分3个连续且不交叠的子信道后，资源块集合0的剩余RB数为10，与其后的保护带组成一个子信道；资源块集合1的剩余RB数为10，剩余RB作为一个子信道。故资源池包含的子信道一共是8个，子信道大小依次为：12,12,12,24,12,12,12,10。
示例六
在示例六中，第一预设子规则采用上述规则a4-04，或者规则d41、d43和d44的组合。
图8示出了一实施例提供的一种采用规则a4-04，或者规则d41、d43和d44的组合确定剩余资源块所属的子信道的示意图。如图8所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量与保护带包含的资源块数量之和大于子信道大小，剩余资源块与该保护带中的部分资源块组成一个大小等于子信道大小的子信道；对于资源块集合1，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量与保护带包含的资源块数量之和小于或者等于子信道大小，剩余资源块与该保护带中的所有资源块组成一个子信道；对于资源块集合2，从资源块集合的 第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块作为一个子信道。故资源池包含的子信道一共是12个。
示例七
在示例七中，第一预设子规则采用上述规则a4-08，或者规则d3、d4、d5和d7的组合。
图9示出了一实施例提供的一种采用规则a4-08，或者规则d3、d4、d5和d7的组合确定剩余资源块所属的子信道的示意图。如图9所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量小于第一门限，剩余资源块不属于任何子信道；对于资源块集合1，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量大于或者等于第一门限且剩余资源块数量与保护带包含的资源块数量之和小于或者等于子信道大小，剩余资源块与该保护带中的所有资源块组成一个子信道；对于资源块集合2，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量大于或者等于第一门限且剩余资源块后面没有保护带，剩余资源块作为一个子信道。故资源池包含的子信道一共是11个。
示例八
在示例八中，第一预设子规则采用上述规则a4-09，或者规则d16、d17、d18和d20的组合。
图10示出了一实施例提供的一种采用规则a4-09，或者规则d16、d17、d18和d20的组合确定剩余资源块所属的子信道的示意图。如图10所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量与子信道大小的比值小于第二门限，剩余资源块不属于任何子信道；对于资源块集合1，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量与子信道大小的比值小于第二门限，剩余资源块不属于任何子信道；对于资源块集合2，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，剩余资源块的数量与子信道大小的比值大于或者等于第二门限且剩余资源块后面没有保护带，剩余 资源块作为一个子信道。故资源池包含的子信道一共是10个。
示例九
在示例九中，第一预设子规则采用上述规则a4-10，或者规则c6，或者规则d1和d8的组合。
图11示出了一实施例提供的一种采用规则a4-10，或者规则c6，或者规则d1和d8的组合确定剩余资源块所属的子信道的示意图。如图11所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。假设第一门限为10，对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，资源块集合0剩余1个RB，小于第一门限，因此剩余资源块与资源块集合0中按照子信道大小依次划分的子信道数量个子信道中的最后一个子信道合并成一个子信道；对于资源块集合1和2，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，均剩余10个RB，等于第一门限，因此资源块集合1和2中剩余RB分别作为一个子信道。故资源池包含的子信道一共是11个。
示例十
在示例十中，第一预设子规则采用上述规则a4-11，或者规则c7，或者规则d14和d21的组合。
图12示出了一实施例提供的一种采用规则a4-11，或者规则c7，或者规则d14和d21的组合确定剩余资源块所属的子信道的示意图。如图12所示，一个资源池包含3个RB set，即资源块集合0、资源块集合1和资源块集合2。对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。假设子信道大小为12个RB，第二门限为0.8，对于资源块集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，资源块集合0剩余1个RB，剩余RB的数量与子信道大小的比值为1/12＝0.08，小于第二门限，因此剩余资源块与资源块集合0中按照子信道大小依次划分的子信道数量个子信道中的最后一个子信道合并成一个子信道；对于资源块集合1和2，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的3个子信道后，均剩余10个RB，剩余RB的数量与子信道大小的比值为10/12＝0.83，大于第二门限，因此资源块集合1和2中剩余RB分别作为一个子信道。故资源池包含的子信道一共是11个。
示例十一
上述示例一至示例十均是以资源块集合的第一子信道的第一个RB与资源块集合的第一个RB对齐为例，来说明确定剩余资源块所属的子信道的方法的。当资源块集合的第一子信道的第一个RB与资源块集合的最低RB不对齐时，上述所有示例仍然适用。对于一个RB set，仍然从该资源块集合的第一子信道的第一个RB的位置开始按照子信道大小依次划分子信道，因此，如果一个资源块集合的第一子信道的第一个RB相对该资源块集合的最低RB偏移X个RB，且X不为0，则该资源块集合前X个RB不属于任何子信道。
在示例十一中，第一预设子规则采用上述规则a4-01，或者规则c1，或者规则d1和d7的组合。
图13示出了一实施例提供的又一种采用规则a4-01，或者规则c1，或者规则d1和d7的组合确定剩余资源块所属的子信道的示意图。如图13所示，一个资源池包含两个RB set，即资源块集合0和资源块集合1，它们包含的RB数分别是47和45。资源块集合0和资源块集合1之间的保护带包含14个RB，子信道大小为12个RB，第一门限为10。资源块集合0的第一个子信道的第一个RB的位置相对该资源块集合的最低RB偏移1个RB，从资源块集合0的第一个子信道的第一个RB的位置开始在按照子信道大小12个RB依次划分3个连续且不交叠的子信道后，资源块集合0的剩余RB数为47-12*3-1＝10等于第一门限10，因此作为一个子信道；资源块集合1的第一个RB相对该资源块集合的最低RB偏移0个RB(即与该资源块集合的最低RB对齐)，在按照子信道大小12个RB依次划分3个连续且不交叠的子信道后，资源块集合1的剩余RB的数量为45-12*3＝9，小于第一门限，因此不属于任何子信道。故资源池包含的子信道一共是7个，其中，资源块集合0和1分别对应其中的前4个和后3个子信道，子信道大小依次为：12,12,12,10,12,12,12。
在上述十一个示例中，对于后面没有保护带的资源块集合中的剩余资源块，也根据规则确定了其所属于的子信道。在本申请中，也可以配置或者预定义，后面没有保护带的资源块集合中的剩余资源块不属于任何子信道，示例可以参考上述示例，对于上述示例做适当修改即可，例如，最后一个资源块集合中剩余资源块不属于任何子信道。
上述十一个示例仅仅给出了根据部分规则确定RB set的剩余资源块所属的子信道的例子，根据其他规则或者规则组合确定RB set的剩余资源块所属的子信道的方法，也可以采用与上述十一个示例类似的方法给出例子，这里不再一一列举。
在第二种实现方式中，配置信息为资源池对应的子信道的配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小和子信道数量中至少之 一，预设规则包括第二预设子规则。
通信节点确定资源池包括的子信道的方法包括：若资源池包括至少两个RB set，则从资源池的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道；根据第二预设子规则，对划分的子信道进行排除处理；资源池包括的子信道由剩余的所有子信道组成。
一种示例性的，第二预设子规则包括如下至少之一：
规则e1、若子信道没有跨RB set且子信道中包含在RB set中的资源块的数量小于第三门限，则排除子信道。
规则e2、若子信道跨两个RB set且子信道中包含在两个RB set中的资源块的数量均小于第四门限，则排除子信道。

规则e4、若子信道跨两个RB set且子信道中的包含在两个RB set中的资源块的数量与子信道大小的比值均小于第六门限，则排除子信道。
规则e5、若子信道没有跨RB set、子信道中包含在RB set中的资源块的数量小于第三门限且子信道中包含在RB set中的资源块的数量与子信道大小的比值小于第五门限，则排除子信道。
规则e6、若子信道跨两个RB set、子信道中包含在两个RB set中的资源块的数量均小于第四门限且子信道中的包含在两个RB set中的资源块的数量与子信道大小的比值均小于第六门限，则排除子信道。
规则e7、若子信道跨两个RB set、子信道中包含在两个RB set中的资源块的数量均小于第三门限且子信道中的包含在两个RB set中的资源块的数量与子信道大小的比值均小于第五门限，则排除该子信道。
规则e8、若子信道跨两个RB set，则排除该子信道。
本申请中上述规则在不冲突的情况下，可以任意组合，比如规则e1和e3组合、规则e2和e4组合等，本申请实施例对此不作限制。
例如，对于一个资源池，子信道m＝0,1,,nnumSub-1，由nsubCHsize个连续资源块组成，物理资源块的编号nPRB＝nsubCHRBstart+m·nsubCHsize+j，j＝0,1,,nsubCHsize-1。
nsubCHsize是子信道大小，通常，对于一个资源池中的所有RB set，子信道大小是相同的，也就是说子信道大小一般是按照资源池配置的，以使得一个资源 池中子信道大小一致。
nsubCHRBstart是资源池的第一个子信道的第一个RB索引，用于指示资源池的第一个子信道的第一个RB的位置，上述公式中该参数是相对该资源池所在的SL BWP的最低RB索引的索引。高层实体可以为通信节点配置资源池的第一个子信道的第一个RB的位置；或者，预定义资源池的第一个子信道的第一个RB与该资源池的最低RB对齐。对于一个资源池，如果高层实体没有为通信节点配置该资源池的第一个子信道的第一个RB的位置，则通信节点默认该资源池的第一个子信道的第一个RB与该资源池的最低RB对齐。
nnumSub是资源池对应的子信道数量，对一个资源池，从该资源池的第一个子信道的起始资源块位置开始按照子信道大小依次划分nnumSub个连续且不交叠的子信道。一个资源池对应的子信道数量可以由高层实体提供给通信节点；或者，通信节点根据资源池包含的资源块数量和子信道大小获取该资源池对应的子信道数量；或者，通信节点根据资源池包含的资源块数量、资源池的第一个子信道的第一个RB的位置和子信道大小获取该资源池对应的子信道数量。
资源池对应的子信道的总数未必等于nnumSub，例如，可以小于或者等于nnumSub，但也有可能等于nnumSub+1。例如，一个资源池包含两个RB set，每个资源块集合包含105个RB，两个资源块集合之间的保护带为6个RB，即资源池包含216个RB，子信道大小为20个RB。假设该资源池的第一个子信道的第一个RB与该资源块池的最低RB对齐，高层实体配置该资源池的子信道数量nnumSub等于10，资源池划分为10个大小为20个RB的子信道后，资源池内剩余16个RB。假设资源池内剩余的16个RB不属于任何子信道，且根据子信道的排除规则可能排除部分子信道，则该资源池包含的子信道数小于或者等于nnumSub个；假设资源池内剩余的16个RB作为一个子信道，且根据子信道的排除规则没有排除任何子信道，则该资源池包含的子信道数为nnumSub+1个。
在本实现方式中，资源池中的剩余资源块为从该资源池对应的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠子信道后，在资源池的结束位置剩余的资源块。
一个资源池中的剩余资源块的数量可以小于子信道大小，也可以大于或者等于子信道大小。
在本实现方式中，配置信息中的子信道大小，或者上述“按照子信道大小依次划分子信道数量个连续且不交叠的子信道”中的子信道大小，为名义上的子信道大小，如果资源池中的剩余资源块也属于一个子信道，或者剩余的资源块与资源池中按照子信道大小依次划分子信道数量个连续且不交叠的子信道中的最后一个子信道合并成一个子信道，则该子信道的大小通常与名义的子信道大小不相等，当然也可以规定资源池中的剩余资源块不属于任何子信道，这时资源 池中所有的子信道大小相等。
下面提供一些示例，用来解释说明“根据第二预设子规则，对划分的子信道进行排除处理”。
示例十二
在示例十二中，第二预设子规则采用上述规则e1和e2的组合。
图14示出了一实施例提供的一种采用规则e1和e2的组合对划分的子信道进行排除处理的示意图。如图14所示，一个资源池包含3个RB set，即资源块集合0，1和2，相邻资源块集合之间分别是保护带0和1。假设第三门限为8，第四门限也为8，包含保护带中资源的子信道分别是子信道n和子信道m(m>n)；子信道n没有跨资源块集合，子信道n中包含在资源块集合0中的资源块的数量是3，小于第三门限8，因此子信道n被排除；子信道m跨资源块集合1和2，子信道m中包含在资源块集合1和资源块集合2中的资源块的数量分别是9和1，由于只有1小于第四门限8，而9大于第四门限8，所以子信道m没有被排除。
示例十三
在示例十三中，第二预设子规则采用上述规则e3和e4的组合。
图15示出了一实施例提供的一种采用规则e3和e4的组合对划分的子信道进行排除处理的示意图。如图15所示，一个资源池包含3个RB set，即资源块集合0，1和2，相邻资源块集合之间分别是保护带0和1。假设子信道大小为12，第五门限为0.8，第六门限为0.8，包含保护带中资源块的子信道分别是子信道n和子信道m(m>n)；子信道n没有跨资源块集合，子信道n中包含在资源块集合0中的资源块的数量是3，与子信道大小的比值为3/12＝0.25，小于第五门限0.8，因此子信道n被排除；子信道m跨资源块集合1和2，子信道m中包含在资源块集合1和资源块集合2中的资源块的数量分别是9和1，与子信道大小的比值分别为9/12＝0.75和1/12＝0.08，由于0.75和0.08都小于第六门限0.8，所以子信道m也被排除了。
上述两个示例(示例十二和示例十三)仅仅给出了根据部分规则确定资源池包含的子信道的例子，根据其他规则或者规则组合确定资源池包含的子信道的方法，也可以采用与上述两个示例类似的方法给出例子，这里不再一一列举。
在本实现方式中，给出了确定资源池中的剩余资源块对应的子信道的方法。在一实施例中，确定资源池中的剩余资源块对应的子信道的方法，可以采用上述示例中确定资源块集合中的剩余资源块对应的子信道的方法，将“资源块集合”替换为“资源池”即可；或者，协议规定，资源池中的剩余资源块不属于任何子信 道，或者通信节点不期望使用资源池中的剩余资源块。
在第三种实现方式中，配置信息为资源池中每个RB set对应的子信道的配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小和子信道数量中至少之一，预设规则包括第三预设子规则。
通信节点确定资源池包括的子信道的方法包括：对于资源池中的任一RB set，从RB set的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道；根据第三预设子规则，对划分的子信道进行排除处理；资源池包括的子信道由资源池中所有RB set剩余的子信道组成。
一种示例性的，第三预设子规则包括如下至少之一：
规则f1、若子信道中包含在RB set中的资源块的数量小于第七门限，则排除子信道。
规则f2、若子信道中包含在RB set中的资源块的数量与子信道大小的比值小于第八门限，则排除子信道。
规则f3、若子信道与下一个RB set交叠或者与下一个RB set的第一个子信道交叠，则排除子信道。
本申请中上述规则在不冲突的情况下，可以任意组合，比如规则f1和f2组合、规则f1和f3组合、规则f2和f3组合、规则f1、f2和f3组合，本申请实施例对此不作限制。
在本实现方式中，通常，对于一个资源池中的所有RB set，子信道大小是相同的，也就是说子信道大小一般是按照资源池配置的，以使得一个资源池中子信道大小一致，本申请也不排除不同RB set配置不同的子信道大小。
在本实现方式中，对于资源池中的每个RB set，高层实体可以为通信节点配置资源块集合的第一个子信道的第一个RB的位置；或者，预定义资源块集合的第一个子信道的第一个RB与该资源块集合的最低RB对齐。对于一个RB set，如果高层实体没有为通信节点配置该资源块集合的第一个子信道的第一个RB的位置，则通信节点默认该资源块集合的第一个子信道的第一个RB与该资源块集合的最低RB对齐。
在本实现方式中，对于资源池中的每个RB set，高层实体可以为通信节点配置子信道数量；或者，如果RB set后面有保护带，则子信道数量由资源块集合与其后面的保护带组成的子带的带宽以及子信道大小计算得到，如果RB set 后面没有保护带，则子信道数量由资源块集合的带宽以及子信道大小计算得到。例如，根据带宽以及子信道大小计算子信道数量的方法可以是，假设带宽包含BW个资源块，子信道大小为S个资源块，则子信道数量为：BW除以S，然后向下取整。
下面提供一些示例，用来解释说明“根据第三预设子规则，对划分的子信道进行排除处理”。
示例十四
在示例十四中，第三预设子规则采用上述规则f1。
图16示出了一实施例提供的一种采用规则f1或规则f2对划分的子信道进行排除处理的示意图。如图16所示，一个资源池包含3个RB set，即资源块集合0，1和2，相邻资源块集合之间分别是保护带0和1。假设子信道大小为15，第七门限为10，包含保护带中资源块的子信道分别是子信道n和子信道m(m>n)；子信道n中包含在资源块集合0中的资源块的数量是10，等于第七门限10，因此子信道n没有被排除；子信道m中包含在资源块集合1中的资源块的数量是2，小于第七门限10，所以子信道m被排除。
示例十五
在示例十五中，第三预设子规则采用上述规则f2。
继续参考图16，一个资源池包含3个RB set，即资源块集合0，1和2，相邻资源块集合之间分别是保护带0和1。假设子信道大小为15，第八门限为0.6，包含保护带中资源块的子信道分别是子信道n和子信道m(m>n)；子信道n中包含在资源块集合0中的资源块的数量是10，与子信道大小的比值为10/15＝0.66，大于第八门限0.6，因此子信道n没有被排除；子信道m中包含在资源块集合1中的资源块的数量是2，与子信道大小的比值为2/15＝0.13，小于第八门限0.6，所以子信道m被排除。
示例十六
在示例十六中，第三预设子规则采用上述规则f3。
图17示出了一实施例提供的一种采用规则f3对划分的子信道进行排除处理的示意图。如图17所示，一个资源池包含2个RB set，即资源块集合0和1，资源块集合0的最后一个子信道(即子信道n)与下一个资源块集合的第一个子信道交叠了，所以，子信道n被排除。
在第四种实现方式中，配置信息为资源池对应的子信道的配置信息，配置 信息包括第一个子信道的起始资源块位置、子信道大小和子信道数量中至少之一。
通信节点确定资源池包括的子信道的方法包括：若资源池包括一个RB set，则从资源池的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道；资源池包括的子信道由划分的所有子信道组成。
在一实施例中，若资源池划分为子信道数量个子信道后有剩余资源块，还可以确定剩余资源块所属的子信道，其方法包括如下至少之一：
若剩余资源块的数量大于或者等于第三门限，则剩余资源块作为一个子信道，资源池还包括该子信道；若剩余资源块的数量与子信道大小的比值大于或者等于第五门限，则剩余资源块作为一个子信道，资源池还包括该子信道；若剩余资源块的数量大于或者等于第三门限且剩余资源块的数量与子信道大小的比值大于或者等于第五门限，则剩余资源块作为一个子信道，资源池还包括该子信道；若剩余资源块的数量小于第三门限，则剩余资源块和按照子信道大小依次划分的子信道数量个子信道中的最后一个子信道合并成一个子信道；若剩余资源块的数量与子信道大小的比值小于第五门限，则剩余资源块和按照子信道大小依次划分的子信道数量个子信道中的最后一个子信道合并成一个子信道；剩余资源块不属于任何子信道。
在第五种实现方式中，配置信息为资源池中每个RB set对应的子信道的配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小和子信道数量中至少之一。
通信节点确定资源池包括的子信道的方法包括：对于资源池中的任一RB set，从RB set的第一个子信道的起始资源块位置开始，按照子信道大小依次划分子信道数量个连续且不交叠的子信道；资源池包括的子信道由资源池中所有RB set对应的子信道组成。
在一实施例中，对于后面有保护带的RB set，该RB set对应的最后一个子信道的结束位置在保护带的结束位置或者在保护带的结束位置之前；对于后面没有保护带的RB set，该RB set对应的最后一个子信道的结束位置在该RB set的结束位置或者在该RB set的结束位置之前。
图18示出了一实施例提供的一种划分子信道的示意图。如图18所示，一个资源池包含两个RB set，即资源块集合0和1，对于每个资源块集合，资源块集合的第一子信道的第一个RB与该资源块集合的第一个RB对齐。对于资源块 集合0，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的n+1个子信道；对于资源块集合1，从资源块集合的第一个子信道的第一个RB位置开始按照子信道大小依次划分的N-n-1个子信道。资源池共包含N个子信道。
在本实现方式中，子信道大小、资源块集合的第一个子信道的第一个RB的位置，子信道数量的确定方式与上述实施例相同，这里不再赘述。
在第六种实现方式中，给出了如何基于资源池包含的子信道进行SL频域资源分配或者频域资源选择，以及如何确定SL传输实际使用的频域资源的方法。
在一实施例中，资源池包含的子信道按照频率由低到高依次连续编号，得到子信道的逻辑索引，对于一个SL传输，通过指示连续L个子信道的逻辑索引(例如，指示起始子信道，从起始子信道开始连续的子信道数量)，来指示为其分配的频域资源。
如果一个SL传输被分配的连续L个子信道没有跨资源块集合(即L个子信道包含在一个资源块集合内，或者包含在一个资源块集合及其后面的保护带内)，则该SL传输只能使用L个子信道中包含在资源块集合中的资源块。即不能使用L个子信道中包含在保护带的资源块。进一步地，对于L个子信道中包含在保护带的资源块，SL传输需要对L个子信道中包含在保护带的资源块做速率匹配，或者，SL传输对L个子信道中包含在保护带的资源块进行打孔。
如果一个SL传输被分配的连续L个子信道跨至少两个相邻资源块集合(即L个子信道包含至少两个相邻资源块集合中资源块)，则该SL传输可以使用L个子信道中包含在资源块集合的资源块，以及相邻资源块集合之间的保护带内的资源块。进一步地，对于L个子信道中不能使用的资源块，SL传输需要对其做速率匹配或者打孔。
在第七种实现方式中，当高层实体指示使能了资源块连续的边链路传输时，通信节点采用本申请中的子信道确定方法。指示的粒度可以是载波，或者BWP，或者资源池。例如，高层实体指示一个载波使能了资源块连续的边链路传输，则对于该载波上的所有BWP中所有资源池，通信节点采用本申请中的子信道确定方法。再比如，高层实体指示一个BWP使能了资源块连续的边链路传输，则对于该BWP中所有资源池通信节点采用本申请中的子信道确定方法，再比如，高层实体指示一个资源池使能了资源块连续的边链路传输，则对于该资源池通信节点采用本申请中的子信道确定方法。
在第八种实现方式中，当高层实体没有指示使能使用交织(interlace)的边链路传输时，通信节点采用本申请中的子信道确定方法。指示的粒度可以是载波或者BWP，或者资源池。例如，高层实体没有指示一个载波使能使用交织的边链路传输，则对于该载波上的所有BWP中所有资源池，通信节点采用本申请中的子信道确定方法。再比如，高层实体没有指示一个BWP使能使用交织的边链路传输，则对于该BWP中所有资源池通信节点采用本申请中的子信道确定方法，再比如，高层实体没有指示一个资源池使能使用交织的边链路传输，则对于该资源池通信节点采用本申请中的子信道确定方法。
图19示出了一实施例提供的一种子信道的确定装置的结构示意图，该装置可以配置于通信节点中，如图19所示，该装置包括：获取模块200和确定模块210。
获取模块200，设置为确定配置信息，配置信息包括第一个子信道的起始资源块位置、子信道大小、子信道数量中的至少之一；确定模块210，设置为根据预设规则和配置信息，确定资源池包括的子信道。
