通信资源确定方法、通信方法、通信节点及介质

具体实施方式
为使本申请的目的、技术方案和优点更加清楚明白，下文中将结合附图对本申请的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
在一个示例性实施方式中，图1a为本申请实施例提供的一种通信资源确定方法的流程示意图，该方法可以适用于确定发送数据的通信资源的情况，该方法可以由通信资源确定装置执行，通信资源确定装置可以由软件和/或硬件实现，并集成在第一通信节点上。第一通信节点可以为发射端的用户终端(User Equipment，UE)。
在基于NR的非授权频谱接入(NR-based Access to Unlicensed Spectrum，NR-U)中在载波上定义了M个连续的交织资源块(Resource block，RB),每个交织内的RB等间隔分布，不同的交织在频域上呈梳状分布，编号从0到M-1。例如，频域上还定义了N个连续的资源块集合RBset，编号从0到N-1，如图1b所示。在对数据资源进行指示时，NR-U采用了两级指示的方式，X+Y，X代表物理上行共享信道(Physical Uplink Shared CHannel，PUSCH)资源使用的交织，Y代表PUSCH资源使用的连续的RBset，从而，用户终端就可以根据指示信息确定数据在带宽部分(Bandwidth part，BWP)内的资源位置。
如图1b所示，在频域上的最小指示单元是1个交织下的一个RBset内的所有物理RB资源。图1c为本申请实施例提供的一种数据通信场景示意图，如图1c所示：SL UE基于SL资源池进行通信，不需要基站来转发数据。
其中SL通信资源池中数据调度的最小单元是子带subchannel，根据配置或者预配置信息，SL资源池由频域W个连续的subchannel组成，通常一个数据占用若干个连续的subchannel，而subchannel是根据配置或者预配置信息确定的若干个连续的RB。
图1d为本申请实施例提供的一种资源池的示意图，参见图1d，在资源指示的时候，只需要指示数据在频域上占用的subchannel起始位置和subchannel使用数目即可确定SL数据的资源位置，数据的发送至少使用一个subchannel。
然而，当SL设备，如第一通信节点和第二通信节点工作在非授权频谱上时，频域的资源占用不再是物理连续的RB了，因此，也无法使用传统的方法来确定SL通信资源池上的资源了。
基于此，如图1a所示，本申请提供的一种通信资源确定方法，包括如下步骤：
S110、对频域资源单元进行编号，确定编号后的多个频域资源单元，所述频域资源单元为一个交织上的一个资源块集合内的所有资源块。
根据NR-U的定义，非授权上最小的调度单元是一个交织上的一个RBset上的物理RB资源，因此本申请把一个交织上的一个RBset上的物理RB资源定义为一个频域最小资源单元，又称频域资源单元，记为MinRBgroup。
本申请可以基于确定的资源池确定通信资源。在确定资源池时，可以基于频域资源确定。
在一个实施例中，本步骤可以对频域资源单元进行编号，以基于编号后的频域资源单元确定资源池。
此处不对编号方式进行限定，相邻频域资源单元间的频域资源单元可以连续，也可以不连续。
S120、基于编号后的频域资源单元确定资源池。
在对频域资源单元编号后，本步骤可以基于编号后的频域资源单元确定资源池。
在一个实施例中，可以将频域资源单元中的部分或全部映射到多个子带上形成资源池。
本实施例不对映射方式进行限定。一个子带内的频域资源可以是连续的，不同子带间的频域资源可以连续，也可以不连续。
S130、从所述资源池内选取通信资源。
在确定资源池后，可以从资源池内的候选资源中选取通信资源。
候选资源可以为形成资源池的资源，候选资源可以为子带，也可以为多个频域资源单元。
S140、在所述通信资源上发送数据。
在选取通信资源后，本步骤可以在通信资源上发送数据。
在一个实施例中，第一通信节点可以认为是发射UE，第二通信节点可以认为是接收UE，第一通信节点在数据发送的时候，可以在L个连续的subchannel中选择O个连续的subchannel进行数据发送。O<＝L。接收UE根据确定的资源池信息在资源池中盲检SL数据。资源池信息可以为表征资源池的信息。
在一个实施例中，根据配置或者预配置SL通信资源池信息，发射UE的物理边链路共享信道(Physical sidelink shared channel，PSSCH)由O(O>＝1,O<＝L)个连续的第一子带频域资源大小的第二子带组成，在L个资源配置表中确定PSSCH的候选位置，然后从候选位置中确定PSSCH的实际发射位置，即从资源池内选取通信资源。
根据配置或者预配置SL资源池，接收UE确定可能的PSSCH的资源位置，然后在可能的资源位置上检测SL数据。
本申请实施例提供的一种通信资源确定方法，对频域资源单元进行编号，确定编号后的多个频域资源单元，所述频域资源单元为一个交织上的一个资源块集合内的所有资源块；基于编号后的频域资源单元确定资源池；从所述资源池内选取通信资源；在所述通信资源上发送数据。利用该方法，能够在非授权频谱上确定资源池，然后基于资源池选取通信资源以实现数据发送。
在上述实施例的基础上，提出了上述实施例的变型实施例，在此需要说明的是，为了使描述简要，在变型实施例中仅描述与上述实施例的不同之处。
在一个实施例中，所述频域资源单元的个数基于载波所配置的信息或者预配置信息确定；
所述载波所配置或者预配置的信息包括：M个交织、带宽部分和Q个资源块集合；
所述带宽部分内包括N个资源块集合，N为小于Q的正整数。M,N和Q为正整数。
假定在SL-U的载波上定义了M个交织，在SL-U的载波的BWP上配置了N个RBset。
SL-U的资源池预配置/配置顺序包括：
首先有SL-U的载波，例如CC1。
其次在该CC1上定义有M个交织；
该CC1上定义了SL BWP；
该CC1上定义了Q个RBset；
SL BWP内包含N个RBset，N<＝Q；
因此可以确定M*N个频域上的最小资源单元。
在一个实施例中，所述频域资源单元的个数为M*N个。
在一个实施例中，对频域资源单元进行编号，确定编号后的多个频域资源单元，包括：
按照交织索引，依次对每个交织内的各个连续的资源块集合进行连续的编号，确定M*N个频域资源单元。

在一个示例中，对频域上的最小资源单元进行编号，包括：先按照交织索引，依次对交织内的各个连续的RBset资源进行连续的编号，编号确定了M*N个频域最小资源单元，编号为0到M*N-1，其中不同交织之间编号连续的MinRBgroup频域资源是连续的，即一个交织上的MinRBgroup从低频到高频编号结束之后，下个相邻交织上的MinRBgroup从高频到低频继续连续编号。

根据频域最小资源单元和subchannel的比例因子，一个subchannel需要映射K个连续的频域最小资源单元。
因此配置L个资源映射表格，Subchannel(r1，r2)表示连续S个subchannel频域资源大小的资源的第(r2+1)个配置，其中，S＝r1+1。r1>＝0,r1<＝L-1，r2>＝0,r2<＝L-1。
