Description

一种进行BWP分配的方法和设备
本申请要求在2018年4月13日提交中国专利局、申请号为201810333176.7、申请名称为“一种进行BWP分配的方法和设备”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
本申请涉及无线通信技术领域，特别涉及一种进行BWP(Bandwidth part，部分带宽)分配的方法和设备。
背景技术
目前，现有的5G新空口技术(New Radio，NR)中，用户设备(User Equipment，UE，也可以称为终端)未强制要求支持在相同的时间单元里采用不同的参数集，同时进行下行接收或上行传输多个频分复用(Frequency Division Multiplex，FDM)的物理信道。而在车到万物(Vehicle to X，V2X)通信中，在满足V2X系统中较高的节点密度和业务量的需求的同时，还需要满足V2X业务的低时延传输的需求，如此以FDM方式进行数据传输则需要被考虑在内。
FDM方式采用不同的参数集进行数据传输。现有的长期演进(Long Term Evolution，LTE)中，在采用FDM方式进行数据传输时，由于子载波间隔是固定的15kHz，同一子帧内，不考虑频偏影响时，FDM的不同的频域资源间不会由于子载波的拖尾信号干扰导致性能下降。
现有的5G NR中定义的参数集(Numerology)包括可调整的子载波间隔(Sub-Carrier Spacing，SCS)、可调整的循环前缀(Cyclic Prefix，CP)等。
而5G NR中定义了多种SCS配置，以及不同的CP配置。当CP配置都为常用配置，而SCS配置不同时，FDM的不同的频域资源间会因为拖尾信号不互为正交，导致互相干扰。
综上所述，现有技术在5G NR下运用FDM方式进行V2X通信时存在子载波的拖尾信号干扰，导致性能下降。
发明内容
本申请提供一种进行BWP分配的方法和设备，用以解决现有技术中存在的在5G NR 下运用FDM方式进行V2X通信时存在子载波的拖尾信号干扰，导致性能下降的问题。
第一方面，本申请提供一种进行BWP分配的方法，该方法包括：
首先根据不同参数集和BWP差异信息的第一映射关系，确定需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息，其中所述第一节点需要在与所述第二节点对应的时间单元内进行BWP分配；然后根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件；如果满足分配条件，则在所述第二节点对应的时间单元内为所述第一节点分配BWP。
上述方法，首先确定第一节点与第二节点的差异信息，再根据差异信息以及第一节点需要分配BWP对应的业务的可靠性要求判断是否满足分配条件，若满足分配条件，则在第二节点对应的时间单元内为第一节点分配BWP。当第二节点可以通过编码增益等可以补偿BWP引入的干扰时，在第二节点对应的时间单元内为第一节点分配BWP。如此可以在运用FDM方式进行数据传输时，避免信号干扰，同时由于采用的是FDM的方式进行数据传输，故在同一时间内可以进行多个数据的传输。满足了V2X系统节点密度和业务量高的需求，同时保证了低时延高可靠性的需要，因而提高了系统性能。
在一种可能的实现方式中，所述分配条件包括下列分配条件中的部分或全部：
分配条件1、所述第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值，且所述第一节点需要分配BWP对应的业务的可靠性等级低于阈值，且所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP匹配的资源；
分配条件2、所述第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值不小于所述最大差异值，且所述第一节点需要分配BWP对应的业务的可靠性等级不低于阈值，且所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源；
其中，所述最大差异值为BWP差异信息中所述第一节点的编码配置信息对应的最大差异值；所述保护间隔信息对应的资源为所述第一节点和所述第二节点的不同参数集对应的保护间隔信息中所述第一节点的编码配置信息对应的资源。
上述方法，当第二节点满足分配条件1时，则确定第一节点可以与第二节点在同一时间单元内进行资源分配。此时，由于第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值，所以采用FDM方式进行数据传输时，可以通过编码增益等可以补偿BWP引入的干扰，进而可以保证V2X业务低时延高可靠的特性，同时由于采用FDM方式进行数据传输，所以，可以满足V2X业务高节点密度和高业务量的特性。
当第二节点满足分配条件2时，则确定第一节点可以与已分配BWP的第二节点在同一时间单元内进行资源分配。此时，由于第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值不小于所述最大差异值，同时第一节点需要分配BWP对应的业务的可靠性等级也较高，此时采用保护间隔以避免拖为信号造成的干扰。
在一种可能的实现方式中，根据不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息。
上述方法，根据第一节点的参数集和第二节点的参数集以及不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息，如此即可根据确定的保护间隔信息进一步判断已分配的第二节点对应的时间单元内能够进行分配的资源中是否有与第一节点需要分配的BWP匹配的资源，进一步确定数据传输的方式。
在一种可能的实现方式中，若满足分配条件2，则在所述第二节点对应的时间单元内为所述第一节点分配BWP，且根据所述保护间隔信息对应的资源在所述第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔。
上述方法，在确定第一节点满足分配条件2时，在所述第二节点对应的时间单元内为所述第一节点分配BWP，根据所述保护间隔信息对应的资源在所述第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔。由于设置了保护间隔，所以可以消除拖尾信号的干扰，如此即可保证在V2X业务传输时的高可靠的业务需求，同时采用FDM的方式进行数据传输，则可以保证V2X业务传输时低时延的业务需求，进而提高了性能。
在一种可能的实现方式中，所述根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件之后，如果不满足分配条件，则采用时分复用(Time Division Multiplex，TDM)方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
上述方法，在不满足分配条件时，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。如此，无法在第二节点的当前的时间单元里为第一节点分配资源时，也可以采用TDM的方式在与第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
第二方面，本申请实施例提供一种进行BWP分配的设备，该设备包括：处理器、存储器和收发机；
其中，所述处理器，用于读取存储器中的程序并执行：
根据不同参数集和BWP差异信息的第一映射关系，确定需要分配BWP的第一节点和 已分配BWP的第二节点的不同参数集对应的BWP差异信息，其中所述第一节点需要在与所述第二节点对应的时间单元内进行BWP分配；根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件；如果满足分配条件，则在所述第二节点对应的时间单元内为所述第一节点分配BWP。
在一种可能的实现方式中，所述分配条件包括下列分配条件中的部分或全部：
分配条件1、所述第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值，且所述第一节点需要分配BWP对应的业务的可靠性等级低于阈值，且所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP匹配的资源；
分配条件2、所述第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值不小于所述最大差异值，且所述第一节点需要分配BWP对应的业务的可靠性等级不低于阈值，且所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源；
其中，所述最大差异值为BWP差异信息中所述第一节点的编码配置信息对应的最大差异值；所述保护间隔信息对应的资源为所述第一节点和所述第二节点的不同参数集对应的保护间隔信息中所述第一节点的编码配置信息对应的资源。
在一种可能的实现方式中，所述处理器具体用于：
根据不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息。
在一种可能的实现方式中，所述处理器还用于：
若满足分配条件2，则在所述第二节点对应的时间单元内为所述第一节点分配BWP，且根据所述保护间隔信息对应的资源在所述第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔。

在根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件之后，如果不满足分配条件，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
第三方面，本申请实施例提供一种进行BWP分配的设备，该设备包括：

为了提升交通系统的安全性和智能化，智能交通系统的概念正逐渐兴起。智能交通可以利用新一代的通信网络和数据处理能力，提高现有交通系统的整体效率，降低能量损耗，增加运输的安全和便捷程度。
近年来智能交通系统的开发将主要集中在智能公路交通系统领域，也就是俗称的车联 网。其中V2X技术借助车-车，车与路测基础设施、车与路人之间的无线通信，实时感知车辆周边状况进行及时预警成为当前世界各国解决道路安全问题的一个研究热点。根据美国交通部提供的数据，V2V技术可帮助预防80％各类交通事故的发生。
搭载V2X功能汽车是搭载先进的车载传感器、控制器、执行器等装置，并融合现代通信与网络技术，实现车与X(人、车、路、后台等)智能信息的交换共享，具备复杂的环境感知、智能决策、协同控制和执行等功能，可实现安全、舒适、节能、高效行驶，并最终可替代人来操作的新一代汽车。
如此，在V2X通信中，将有大量数据需要传输，同时还需要及时的反馈，即V2X系统具有较高的节点密度和业务量的需求的同时，还需要满足V2X业务的低时延高可靠的传输需求，如此以FDM方式进行数据传输则需要被考虑在内。
现有的5G NR中，UE未强制要求支持在相同的时间单元里采用不同的参数集(Numerology)，同时进行下行接收或上行传输多个FDM的物理信道。
其中，5G NR中定义的参数集包括可调整的SCS、可调整的循环前缀(Cyclic Prefix，CP)等。
在5G NR中定义了多种SCS配置，以及不同的CP配置。本申请实施例中设定CP配置均为常用配置，不考虑不同的CP配置带来的不同处理方法，仅考虑参数集中的可调整的SCS不同的处理方法。当采用FDM的方式进行数据传输，且参数集中的可调整的SCS配置不同时，FDM的不同的频域资源间会因为拖尾信号不互为正交，导致互相干扰。
现有技术在消除拖尾信号的干扰时不考虑设置保护间隔时，只在接收时依靠接收处理的增益来抵抗拖尾信号叠加产生的干扰，一般采用的增益有：编码增益，接收分集增益，重传合并增益等。当FDM的不同频域资源大小差异较大时，系统噪声较大，依靠以上的增益很难保证高可靠的V2X业务。
另一方面，在消除拖尾信号的干扰时可以在发端进行加窗过滤处理。此方法中，如果窗口过滤实现的阶数较低则信号过滤效果不理想，干扰影响仍会导致性能下降；如果窗口过滤实现的阶数较高虽然信号过滤效果较好，但仍存留残余干扰影响，而且发端处理复杂度会显著增加。
显而易见，上述方法均具有一定的局限性，不能完全消除拖尾信号的干扰。因此，本申请实施例将提供一种进行BWP分配的方法，使得在V2X通信中以FDM方式进行数据传输，以满足V2X系统的高节点密度和高业务量的特性的同时，还满足V2X业务的低时延传输的需求。
其中，本申请实施例中的执行主体可以是网络侧设备或第一节点。网络侧设备可以是 基站；第一节点和第二节点可以是移动设备，如手机，V2X系统中的汽车等。
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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它实施例，都属于本申请保护的范围。
如图1所示，本申请实施例提供一种进行BWP分配的方法，该方法包括：
步骤100，根据不同参数集和BWP差异信息的第一映射关系，确定需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息，其中所述第一节点需要在与所述第二节点对应的时间单元内进行BWP分配；
步骤101，根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件；
步骤102，如果满足分配条件，则在所述第二节点对应的时间单元内为所述第一节点分配BWP。
本申请实施例中，首先确定第一节点与第二节点的差异信息，再根据差异信息以及第二节点具体的编码配置确定第一节点与第二节点差异的最大差异值，然后根据最大差异值确定具体的分配条件，在判断确定第二节点满足分配条件时，在第二节点对应的时间单元内为第一节点分配BWP。当第二节点可以通过编码增益等可以补偿BWP引入的干扰时，在第二节点对应的时间单元内为第一节点分配BWP。如此，可以在运用FDM方式进行数据传输时，避免信号干扰，同时由于采用的是FDM的方式进行数据传输，故在同一时间内可以进行多个数据的传输。满足了V2X系统节点密度和业务量高的需求，同时保证了低时延高可靠性的需要，因而提高了系统性能。
下面将对本申请实施例提供的一种进行BWP分配的方法进行详细说明。
在步骤100中，首先根据不同参数集和BWP差异信息的第一映射关系，确定需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息，其中所述第一节点需要在与所述第二节点对应的时间单元内进行BWP分配。
在具体实施时，当有需要分配BWP的第一节点需要在与已分配BWP的第二节点对应的时间单元内进行BWP分配时，首先会根据第一节点的参数集和第二节点的参数集以及不同参数集和BWP差异信息的第一映射关系，确定有需要分配BWP的第一节点需要在与已分配BWP的第二节点的不同参数集对应的BWP差异信息。如此可以根据确定的BWP差异信息进一步的确定第一节点是否可以与所述第二节点在同一时间单元内进行BWP分配。
其中，确定需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息所依据的不同参数集和BWP差异信息的第一映射关系是给定的时间单元内，设置的不同参数集间，不同的编码方配置下，第一节点与第二节点分配的BWP的大小差异的最大差异值的映射关系，根据第一节点与第二节点之间的差异以及第一节点的编码配置可以确定第一节点与第二节点间的差异信息。给定的时间单元内，设置的不同参数值间的BWP的大小差异的最大差异值的映射关系表现形式多样。如下面表1即为不同参数集和BWP差异信息的第一映射关系的一种表现形式。
在表1中，V2X系统中有的3个不同参数集，分别为N1、N2和N3，则表1第一行表示的是参数集N1和参数集N2之间，若采用的编码配置为C1，则两个节点对应的BWP差异的最大差异值为1MHz；若采用的编码配置为C2，则两个节点对应的BWP差异的最大差异值为3MHz；
第二行表示的是参数集N1和参数集N3之间，若采用的编码配置为C1，则两个节点对应的BWP差异的最大差异值为2MHz；若采用的编码配置为C2，则两个节点对应的BWP差异的最大差异值为4MHz；
第三行表示的是参数集N2和参数集N3之间，若采用的编码配置为C1，则两个节点对应的BWP差异的最大差异值为4MHz；若采用的编码配置为C2，则两个节点对应的BWP差异的最大差异值为8MHz。
如此在本申请实施例具体实施时，在确定需要分配BWP的第一节点的参数集和已分配BWP的第二节点的参数集确定后，即可确定第一节点和第二节点不同参数集对应的BWP差异信息。
例如：假设5G NR V2X系统中有3个不同的参数集，分别为N1、N2和N3，有两种编码配置C1和C2；假设设置不同参数集间的BWP的大小差异映射表如表1所示。
表1：不同参数集间的BWP的大小差异映射关系表

例1、假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内。
则可以确定已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异信息是 参数集N1与参数集N2之间的差异信息，进而确定已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异信息为：
若需要分配BWP的节点B采用的编码配置为C1，则已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异的最大差异值为1MHz；
若需要分配BWP的节点B采用的编码配置为C2，则已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异的最大差异值为2MHz。
例2、参见表1，假设目前有已分配BWP的节点A的业务配置参数集为N3，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内。
则可以确定已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异信息是参数集N2与参数集N3之间的差异消息，进而确定已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异信息为：
若需要分配BWP的节点B采用的编码配置为C1，则已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异的最大差异值为4MHz；
若需要分配BWP的节点B采用的编码配置为C2，则已分配BWP的节点A与需要分配BWP的节点B对应的BWP差异的最大差异值为8MHz。
在确定出需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息后，需要根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求做进一步的判断。
在执行步骤102之前，根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件。
在具体实施中，在确定出需要分配BWP的第一节点和已分配BWP的第二节点的不同参数集对应的BWP差异信息后，会根据得到的确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件，只有当第一节点满足分配条件时，才能确定第一节点可以与第二节点在同一时间单元内进行资源分配。
具体实施中，一种可选的实施方式为，有两组用于判断的分配条件。
分配条件1：
1、所述第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值；
2、所述第一节点需要分配BWP对应的业务的可靠性等级低于阈值；
3、所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分 配的BWP匹配的资源。
其中，所述最大差异值为BWP差异信息中所述第一节点的编码配置信息对应的最大差异值。
当第二节点满足所有上述条件时，则确定第一节点可以与第二节点在同一时间单元内进行资源分配。此时，由于第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值，所以采用FDM方式进行数据传输时，可以通过编码增益等可以补偿BWP引入的干扰，进而可以保证V2X业务低时延高可靠的特性，同时由于采用FDM方式进行数据传输，所以，可以满足V2X业务高节点密度和高业务量的特性。
例如：假设5G NR V2X系统中有3个不同的参数集，分别为N1、N2和N3，有两种编码配置C1和C2；预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，假设设置不同参数集间的BWP的大小差异映射表参见上面的表1。
例1、假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内，需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，需要分配BWP的节点B采用编码配置为C2，同时节点B需要分配BWP对应的业务的可靠性等级为2，且已分配BWP的节点A对应的时间单元内有相邻的20MHz连续空闲频域资源可以使用。
则当需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，同时采用的编码配置为C2，则根据表1可知BWP的大小最大差异值为2MHz，而节点A的BWP与节点B的BWP的差异值为1MHz，小于最大差异值2MHz，故节点B满足分配条件1的第一条要求；
且节点B需要分配BWP对应的业务的可靠性等级为2，而预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，则节点B需要分配BWP对应的业务的可靠性等级低于阈值，故节点B满足分配条件1的第二条要求；
且需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，已分配BWP的节点A对应的时间单元内有相邻的20MHz连续空闲频域资源可以使用，则确定需要分配BWP的节点B在与已需要分配BWP的节点A相同的时间单元内有相邻的19MHz连续空闲频域资源可以使用，故节点B满足分配条件1的第三条要求。
综上，节点B满足分配条件1的所有要求，则确定节点B满足分配条件1，进而执行步骤102。
在步骤102中，如果满足分配条件，则在所述第二节点对应的时间单元内为所述第一节点分配BWP。
具体实施中，在确定满足分配条件后，在所述第二节点对应的时间单元内为所述第一节点分配BWP。如此，在确定第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值小于所述最大差异值，且第一节点需要分配BWP对应的业务的可靠性等级低于阈值时，可以通过编码增益等补偿BWP引入的干扰；同时第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP匹配的资源时，在所述第二节点对应的时间单元内为所述第一节点分配BWP。
可选的，在根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件之后，如果不满足分配条件，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
具体实施时，若确定第一节点不满足分配条件1时，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。如此，即使无法在与已分配BWP的第二节点相同的时间单元里为第一节点分配BWP时，也可以采用TDM方式的方式在与第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
例如：假设5G NR V2X系统中有3个不同的参数集设置N1、N2和N3，有两种编码配置C1和C2；预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，假设设置不同参数集间的BWP的大小差异映射关系参见表1。
例1、假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内，节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，需要分配BWP的采用编码配置为C2，同时节点B需要分配BWP对应的业务的可靠性等级为2，且已分配BWP的节点A对应的时间单元内有相邻的18MHz连续空闲频域资源可以使用。
则当需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，采用编码配置为C2，则根据表2可知BWP的大小最大差异值为2MHz，而已分配BWP的节点A的BWP与需要分配BWP的节点B的BWP的差异值为1MHz，小于最大差异值2MHz，故节点B满足分配条件1的第一条要求；
且节点B需要分配BWP对应的业务的可靠性等级为2，而预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，则节点B需要分配BWP对应的业务的可靠性等级 低于阈值，故节点B满足分配条件1的第二条要求；
且需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝19MHz，已分配BWP的节点A对应的时间单元内有相邻的18MHz连续空闲频域资源可以使用，则确定需要分配BWP的节点B在与已分配BWP的节点A相同的时间单元内没有相邻的19MHz连续空闲频域资源可以使用，故节点B不满足分配条件1的第三条要求。
综上，节点B不满足分配条件1的所有要求，则确定需要分配BWP的节点B不满足分配条件1，进而采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
分配条件2：
1、第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值不小于所述最大差异值；
2、所述第一节点需要分配BWP对应的业务的可靠性等级不低于阈值；
3、所述第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源；
其中，所述保护间隔信息对应的资源为所述第一节点和所述第二节点的不同参数集对应的保护间隔信息中所述第一节点的编码配置信息对应的资源。
当需要分配BWP的第一节点满足所有上述条件时，则确定第一节点可以与已分配BWP的第二节点在同一时间单元内进行资源分配。此时，由于第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值不小于所述最大差异值，同时第一节点需要分配BWP对应的业务的可靠性等级也较高，此时采用保护间隔以避免拖尾信号造成的干扰。
具体实施中，在判断是否满足分配条件2时，还需要确定第二节点对应的时间单元内有能够进行分配的资源中是否有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源。
可选的，根据不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息。
具体实施中，根据第一节点的参数集和第二节点的参数集以及不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息，如此即可根据确定的保护间隔信息进一步判断已分配的第二节点对应的时间单元内能够进行分配的资源中是否有与第一节点需要分配的BWP匹配的资源，进一步确定数据传输的方式。
其中，不同参数集和保护间隔信息的第二映射关系是指给定的时间单元内，设置不同参数集间的频域保护间隔映射关系，表示的是不同参数集间，不同的编码配置下，第一节点与第二节点之间设置的频域保护间隔带宽的大小。
例如，参见表2，V2X系统中有的3个不同参数集，分别为N1、N2和N3，则表2第一行表示的是参数集N1和参数集N2之间，若采用的编码配置为C1，则两个节点对应的频域保护间隔带宽为30MHz；若采用的编码配置为C2，则两个节点对应的频域保护间隔带宽为60MHz；
第二行表示的是参数集N1和参数集N3之间，若采用的编码配置为C1，则两个节点对应的频域保护间隔带宽为120MHz；若采用的编码配置为C2，则两个节点对应的频域保护间隔带宽为240MHz；
第三行表示的是参数集N2和参数集N3之间，若采用的编码配置为C1，则两个节点对应的频域保护间隔带宽为240MHz；若采用的编码配置为C2，则两个节点对应的频域保护间隔带宽为480MHz。
如此在本申请实施例具体实施时，在确定需要分配BWP的第一节点的参数集和已分配BWP的第二节点的参数集确定后，且确定需要分配BWP的第一节点的参数集和已分配BWP的第二节点的参数集之间的BWP差异值不小于所述最大差异值，即可根据不同参数集和保护间隔信息的第二映射关系确定第一节点和第二节点不同参数集对应的保护间隔信息。
例如：假设5G NR V2X系统中有3个不同的参数集设置N1、N2和N3，有两种编码配置C1和C2；预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，假设设置不同参数集间间的频域保护间隔映射表如下：
表2：不同参数集间的频域保护间隔映射表

例1、参见表2，假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内。
则可以确定已分配BWP的节点A与需要分配BWP的节点B对应的保护间隔信息是参数集N1与参数集N2之间的保护间隔消息，进而确定已分配BWP的节点A与需要分配 BWP的节点B对应的保护间隔信息为：
若需要分配BWP的节点B采用的编码配置为C1，则已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为30MHz；
若需要分配BWP的节点B采用的编码配置为C2，则已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为60MHz。
例2、参见表2，假设目前有已分配BWP的节点A的业务配置参数集为N2，需要分配BWP的节点B的业务配置参数集为N3。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内。
则可以确定已分配BWP的节点A与需要分配BWP的节点B对应的保护间隔信息是参数集N2与参数集N3之间的保护间隔消息，进而确定已分配BWP的节点A与需要分配BWP的节点B对应的保护间隔信息为：
若需要分配BWP的节点B采用的编码配置为C1，则已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为240MHz；
若需要分配BWP的节点B采用的编码配置为C2，则已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为480MHz。
在可以根据不同参数集和保护间隔信息的第二映射关系，确定所述第一节点和所述第二节点的不同参数集对应的保护间隔信息后，则下面将根据分配条件2对第一节点进行判断进行举例说明。
例如：假设5G NR V2X系统中有3个不同的参数集设置N1、N2和N3，有两种编码配置C1和C2；预设第一节点需要分配BWP对应的业务的可靠性等级的阈值为5，假设设置不同参数集间的BWP的大小差异映射关系参见表1，不同参数集间的频域保护间隔映射关系参见图2。
例1、假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内，需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝10MHz，需要分配BWP的采用的编码配置为C2，同时节点B需要分配BWP对应的业务的可靠性等级为7，且已分配BWP的节点A对应的时间单元内有相邻的80MHz连续空闲频域资源可以使用。
则当需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝10MHz，采用编码配置为C2，则根据表1可知BWP的大小最大差异为2MHz，而已分配BWP的节点A的BWP与需要分配BWP 的节点B的BWP的差异值为10MHz，显然大于最大差异值2MHz，故需要分配BWP的节点B满足分配条件2的第一条要求；
且节点B需要分配BWP对应的业务的可靠性等级为7，而预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，则节点B需要分配BWP对应的业务的可靠性等级高于阈值，故需要分配BWP的节点B满足分配条件2的第二条要求。
且已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2，需要分配BWP的节点B采用的编码配置为C2，则确定已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为60MHz；此时需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝10MHz，而已分配BWP的节点A对应的时间单元内有相邻的80MHz连续空闲频域资源可以使用，故第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源，故需要分配BWP的节点B满足分配条件2的第三条要求。
综上，需要分配BWP的节点B满足分配条件1的所有要求，则确定需要分配BWP的节点B满足分配条件1，进而执行步骤102。
在步骤102中，如果满足分配条件，则在所述第二节点对应的时间单元内为所述第一节点分配BWP。
具体实施中，在确定满足分配条件后，在所述第二节点对应的时间单元内为所述第一节点分配BWP。如此，在确定第一节点需要分配的BWP和所述第二节点已分配的BWP的差异值大于所述最大差异值，且第一节点需要分配BWP对应的业务的可靠性等级不小于设定阈值时，即可以通过设置保护间隔来消除拖尾信号的干扰；同时第二节点对应的时间单元内能够进行分配的资源中有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源时，在所述第二节点对应的时间单元内为所述第一节点分配BWP。
可选的，若满足分配条件2，则在所述第二节点对应的时间单元内为所述第一节点分配BWP，且根据所述保护间隔信息对应的资源在所述第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔。
具体实施时，在确定第一节点满足分配条件2时，在所述第二节点对应的时间单元内为所述第一节点分配BWP，根据所述保护间隔信息对应的资源在所述第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔。由于在第一节点的BWP和所述第二节点的BWP之间设置了保护间隔，所以可以消除拖尾信号的干扰，如此即可保证在V2X业务传输时的高可靠的业务需求，同时采用FDM的方式进行数据传输，则可以保证V2X业务传 输时低时延的业务需求，进而提高了性能。
例如，参见表2，假设目前有已分配BWP的节点A的业务配置参数集为N2，需要分配BWP的节点B的业务配置参数集为N3。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内，已确定需要分配BWP的节点B满足分配条件2，且采用的编码配置为C1。
则可以确定已分配BWP的节点A与需要分配BWP的节点B对应的保护间隔信息为，进一步的根据需要分配BWP的节点B采用的编码配置为C1，确定已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为240MHz。
确定出已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔带宽为240MHz后，在第二节点对应的时间单元内为所述第一节点分配的BWP，且在第一节点的BWP和所述第二节点的BWP之间设置频域保护间隔，频域保护间隔带宽为240MHz。
可选的，在根据确定的BWP差异信息和所述第一节点需要分配BWP对应的业务的可靠性要求，判断是否满足分配条件之后，如果不满足分配条件，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
具体实施时，若确定第一节点不满足分配条件时，则采用TDM方式在与所述第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。如此，无法在第二节点的当前的时间单元里为第一节点分配资源时，也可以采用TDM方式的方式在与第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
例如：假设5G NR V2X系统中有3个不同的参数集，分别为N1、N2和N3，有两种编码配置C1和C2；预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，假设设置不同参数集间的BWP的大小差异映射关系参见表1，不同参数集间的频域保护间隔映射关系参见表2。
例1，假设目前有已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2。节点A已分配资源，且分配的BWP为BWP(A)＝20MHz在给定的时间单元内，需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且需要分配的BWP为BWP(B)＝10MHz，采用编码配置为C2，同时节点B需要分配BWP对应的业务的可靠性等级为7，且已分配BWP的节点A对应的时间单元内有相邻的50MHz连续空闲频域资源可以使用。
则当需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝10MHz，采用编码配置为C2，则根据表1可知BWP的大小最大差异值为2MHz，而已分配BWP的节点A的BWP与需要分配BWP 的节点B的BWP的差异值为10MHz，显然大于最大差异值2MHz，故需要分配BWP的节点B满足分配条件2的第一条要求；
且节点B需要分配BWP对应的业务的可靠性等级为7，而预设第二节点需要分配BWP对应的业务的可靠性等级的阈值为5，则节点B需要分配BWP对应的业务的可靠性等级高于阈值，故需要分配BWP的节点B满足分配条件2的第二条要求。
且已分配BWP的节点A的业务配置参数集为N1，需要分配BWP的节点B的业务配置参数集为N2，采用编码配置为C2，则确定已分配BWP的节点A与需要分配BWP的节点B对应的频域保护间隔为60MHz；此时需要分配BWP的节点B想以FDM方式在与已分配BWP的节点A相同的时间单元内进行资源分配，且分配的BWP为BWP(B)＝10MHz，而已分配BWP的节点A对应的时间单元内有相邻的50MHz连续空闲频域资源可以使用，故第二节点对应的时间单元内能够进行分配的资源中没有与所述第一节点需要分配的BWP和保护间隔信息对应的资源匹配的资源，故需要分配BWP的节点B不满足分配条件2的第三条要求。
综上，需要分配BWP的节点B不满足分配条件2的所有要求，则确定需要分配BWP的节点B不满足分配条件1，进而采用TDM方式在与第二节点对应的时间单元不同的时间单元内以FDM方式分配BWP。
