技术领域
本发明涉及通信技术领域，特别涉及一种资源选择方法及设备。
背景技术
在新空口(New Radio,NR)技术中，NR SL(sidelink，旁链路)资源分配方式有两种，一种基于基站调度(mode 1)，另一种基于用户设备UE自主资源选择(mode 2)。
其中，对于基站调度的资源分配方式，UE用于数据传输的sidelink资源由基站决定，并通过下行信令通知发送TX UE；对于UE自主选择的资源分配方式，UE在(预)配置的资源池中选择可用的传输资源，UE在资源选择之前先进行信道监听，根据信道监听结果选择出干扰较小的资源集合，再从所述资源集合中随机选择用于传输的资源。
然而，基于UE自主资源选择的方案，对于sidelink的组播通信，即一个UE向组内其它UE进行信息传输，组内UE在发送信息时，由于无法收到其他组内UE向其发送的信息，往往会造成传输资源的可靠性较低。
发明内容
本发明实施例提供一种资源选择方法及设备，以解决用户设备自主选择资源时所存在的传输资源的可靠性较低的问题。
为了解决上述技术问题，本发明是这样实现的：
第一方面，本发明的实施例提供了一种资源选择方法，应用于用户设备，包括：

第三方面，本发明实施例还提供了一种用户设备，包括处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序，所述计算机程序被所述处理器执行时实现如上所述的资源选择方法的步骤。
第四方面，本发明实施例还提供了一种计算机可读存储介质，所述计算机可读存储介质上存储有计算机程序，所述计算机程序被处理器执行时实现如上所述的资源选择方法的步骤。
这样，本发明实施例中，用户设备通过确定作为第二资源集合的子集的第一资源集合，能够在根据该第一资源集合选取目标资源时，避免资源选择的冲突，提升通信的可靠性。

具体实施方式
为使本发明要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。为了方面描述，下文‘/’符号等同于或者。
本发明实施例的方法应用于用户设备，用户设备(user equipment，UE)可以指接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(sessioninitiation protocol，SIP)电 话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备。
如图1所示，本发明实施例的一种资源选择方法，应用于用户设备，包括：
步骤101，确定第一资源集合，所述第一资源集合为第二资源集合的子集。
可选地，第二资源集合是协议定义，或者，预配置，或者，目标节点配置，或者，目标节点动态指示的资源集合，其中目标节点可为控制节点或传输节点(如该用户设备传输的对端设备)。如此，通过该步骤确定的第一资源集合，由于第一资源集合为第二资源集合的子集，就能够在更小的范围内进传输资源的选择。
步骤102，根据所述第一资源集合选取目标资源。
本步骤中，在步骤101确定了第二资源集合的子集后，将进一步根据该第一资源集合，完成目标资源的选取。
这样，按照上述步骤101和步骤102，本发明实施例的方法，用户设备在自主选择资源时，通过确定作为第二资源集合的子集的第一资源集合，能够在根据该第一资源集合选取目标资源时，避免资源选择的冲突，提升通信的可靠性。
其中，第二资源集合可以是一个或多个载波、一个或多个部分带宽(Bandwidth Part，BWP)、一个或多个资源池的全部或者部分资源。可选地，第二资源集合是用户设备所属的用户设备组(UE group)所选择的资源集合或被分配的资源集合，例如，一个UE group内的UE选用资源池内的一组资源，或者控制节点为一个UE group分配的一组资源，或者一个UE group的组头UE选择的一组资源等等。
该实施例中，可选地，所述第一资源集合是所述第二资源集合基于以下至少一项参数划分的子集：
子集的大小；
起始位置；
目标个数；
周期。
其中，子集的大小是第二资源集合的一个子集的时频颗粒度和/或频颗粒度，起始位置是第二资源集合的一个子集起点，目标个数是第二资源集合的子集总数，周期为第二资源集合的一个子集与子集间隔的总长度。以第二资源集合是资源池为例，针对资源池划分的子集，子集的大小是该子集的时频颗粒度和/或频颗粒度，时域颗粒度可为一个或多个时隙(slot)、一个或多个子时隙sub-slot、一个或多个逻辑时隙(logical slot)或者一个或多个逻辑子时隙(logical sub-slot)，频域颗粒度为资源池的带宽、一个或多个子信道(sub channel)、一个或多个物理资源块(Physical Resource Block,PRB)；起始位置是第二资源集合的一个子集的时和/或频起始位置；目标个数可为时域的个数和/或频域的子集个数。
可选地，所述至少一项参数通过协议定义，或者，预配置，或者，控制节点配置，或者，控制节点指示，或者，第一预设策略确定。
其中，配置可通过高层信令，如无线资源控制(Radio Resource Control，RRC)信令，旁链路无线资源控制(PC5-RRC)信令或旁链路无线资源控制(PC5-S)信令等配置。而控制节点指示，可以是可通过物理层或者部分高层信令的动态指示，如下行控制信息(Downlink Control Information，DCI)、旁链路控制信息(Sidelink Control Information，SCI)或者媒体接入控制层控制单元(Media access Control Layer Control Element，MAC CE)。控制节点可以是基站，UE分组的组头，远程用户单元(Remote Subscriber Unit，RSU)或者中继设备relay UE等。
而对于第一预设策略确定参数的实现，该实施例中，可选地，所述第一预设策略的内容项包括以下至少一项：
所述用户设备的分组信息；
所述用户设备旁链路无线资源控制连接的数量；
所述用户设备的待传输数据的大小。
如此，可根据UE的分组信息确定参数，如分组信息指示组内UE的个数，得到第二资源集合划分的子集的目标个数，该目标个数等于组内UE的 个数，或者，组内UE的个数的整数倍。可根据用户设备旁链路无线资源控制UE PC5-RRC连接的数量确定参数，如对于UE1，第二资源集合划分的子集的目标个数等于该UE1的PC5-RRC连接的数量，或者，该UE1所属组内所有PC5-RRC连接的数量。还可根据UE的待传输数据的大小(如物理资源块(PRB)、子信道(sub-channel)数量)确定参数，如根据要待传输数据的sub-channel数量决定频域的粒度/长度，这样不同传输需求分配不同大小的资源时，可以减少资源分配碎片，提高利用率。
另外，该实施例中，可选地，所述第二资源集合的各个子集具有对应的索引编号。
可选地，所述索引编号的数量等于所述第二资源集合的子集的个数；或者，
所述索引编号的数量通过协议定义，或者，预配置，或者，控制节点配置，或者，控制节点指示，或者，第二预设策略确定。
其中，若索引编号的数量等于第二资源集合的子集的个数，则索引编号与子集是一一对应的。此时，索引编号可以是针对时域/频域，先时域后频域，或者先频域后时域，按照时频增长/递降的方向的顺序编号，当然不排除其他的编号形式。如此，该索引编号可以由如下预设公式计算，例如，第二资源集合的子集的大小以一个logical slot或一个logical slot或多个logical slot或多个slot为时域单位，和/或，一个sub-channel或多个sub-channel为频域单位：
索引编号＝X mod N；
索引编号＝Y mod M；
索引编号＝(Y mod M)*N+(X mod N)
索引编号＝(X mod N)*M+(Y mod M)；
其中，X为当前子集的logical slot或slot索引，当然，X也可以是当前子集的logical slot或slot索引除以子集频域粒度的向上或向下取整，Y为当前子集的sub-channel索引或者sub-channel索引除以子集频域粒度的向上或向下取整，N为第二资源集合中子集的时域长度,M为第二资源集合中子集的频域长度。
对于第二预设策略确定索引编号的实现，该实施例中，可选地，所述第 二预设策略的内容项包括以下至少一项：
所述用户设备的分组信息；
所述第二资源集合的子集的个数。
如此，可根据UE的分组信息确定索引编号，如分组信息指示组内UE的个数，就可得到索引编号个数，该索引编号个数等于组内UE的个数，或者，组内UE的个数的整数倍，则子集的索引编号就按照该索引编号个数重复编号。可根据第二资源集合的子集的个数确定索引编号，如根据第二资源集合的子集的个数，对索引编号个数进行截短，重复延长，循环等操作。
另外，该实施例中，可选地，步骤101包括：
基于以下至少一项信息确定所述第一资源集合：
所述用户设备的组内身份标识ID；
所述用户设备的源ID；
目标用户设备的ID；
时间信息；
旁链路网络ID；
地理位置信息；
资源池ID。
其中，为保证组内UE的发送时间/频率是不重叠，可依据用户设备的组内ID(in-group ID/member ID)、源ID(source ID)中的一种选择第一资源集合，如：
第一资源集合的索引编号＝组内ID mod子集个数/索引编号个数；
第一资源集合的索引编号＝组内ID
第一资源集合的索引编号满足如下条件：第一资源集合的索引编号mod组内UE个数＝组内ID。
当然，还可以通过协议定义，或者，预配置，或者，控制节点配置述第二资源集合的各个子集的索引编号与组内ID的对应关系，由该对应关系选择第一资源集合。
而为达到组内UE/组间UE干扰随机化的目的，可依据用户设备的源ID(source ID)、目标用户设备ID(Destination ID)、时间信息(如旁链路系统 帧号DFN、系统帧号(System Frame Number，SFN)、logical slot number、slot number等)、旁链路同步信号SLSS ID、地理位置信息(如区域(zone)ID或小区(cell)ID等)、资源池ID等选择第一资源集合，如：
第一资源集合的索引编号＝K mod子集个数或索引编号个数，其中K为source ID，Destination ID，DFN，SFN，logical slot number，slot number，SLSS ID，zone ID，cell ID中的一种。
又或者，依据多种信息选择第一资源集合，如：
第一资源集合的索引编号＝[(ID1 mod子集个数或索引编号个数)+(ID2 mod子集个数或索引编号个数)]mod子集个数或索引编号个数；
第一资源集合的索引编号＝(ID1+ID2)mod(子资源个数或索引编号个数)；
其中，ID1为组内ID或源ID，ID2为source ID，Destination ID，DFN，SFN，logical slot number，slot number，SLSS ID，zone ID或cell ID。
当然，也可以在第二资源集合的子集中随机选择子集作为第一资源集合。
应该知道的是，该实施例中，所述ID均可以为实际ID的一部分，例如整个ID bits中的某些最低有效位(Least Significant Bit，LSB)，或者，最高有效位(Most Significant Bit，MSB)。
在确定第一资源集合，UE可在第一资源集合中随机选择目标资源进行传输。但，考虑到传输的可靠性，该实施例中，可选地，步骤102包括：
确定资源选择窗口；
根据所述第一资源集合和所述资源选择窗口，确定第三资源集合；
在所述第三资源集合中选取所述目标资源。
这里，会先确定资源选择窗口，然后结合该资源选择窗口和已确定的第一资源集合，进一步确定第三资源集合，将该第三资源集合作为备选资源集合，最终从第三资源集合中选取目标资源，而通过该第三资源集合中选取的目标资源，将更大程度的避免与其他UE的资源重叠或干扰，达到更佳的传输的可靠性。
在选取目标资源之后，可选地，还包括：
根据所述第一资源集合对应的功率控制参数，在所述目标资源上发送数 据。
例如，根据第一资源集合对应的功率控制参数如初始功率P0/路损调整因子alpha，在目标资源上发送数据；根据第一资源集合对应的功率控制参数如发送功率的增量值、功率谱密度(Power Spectral Density，PSD)的增量值或者每个资源粒子的能量EPRE的增量值，在目标资源上进行动态的发送数据。
下面，结合具体场景说明本发明实施例的方法的应用：
当前场景中，UE-A、UE-B和UE-C为同组UE，其中，UE-A的member ID为#2，UE-B的member ID为#3，UE-C的member ID为#4，资源池(即第二资源集合)分为8个子集，其索引编号从#1～#8。
若UE通过公式：索引编号＝组内ID mod子集个数，选择与其相匹配的第一资源集合，则如图2所示，UE-A的第一资源集合为该资源池的#2子集，UE-B的第一资源集合为该资源池的#3子集，UE-C的第一资源集合为该资源池的#4子集。
当然，子集的划分还可以是基于UE group占用的资源集合决定，如图3所示，将该资源集合分为8个子集，其索引编号从#1～#8。UE通过索引编号＝组内ID mod子集个数，选择与其相匹配的子集。
综上所述，本发明实施例的方法，用户设备在自主选择资源时，通过确定作为第二资源集合的子集的第一资源集合，能够在根据该第一资源集合选取目标资源时，避免资源选择的冲突，提升通信的可靠性。
