技术领域
本发明涉及无线通信技术，尤指一种资源选择方法及装置，以及一种资源配置方法及装置和相关计算机存储介质。
背景技术
近年来，近距离通信，如D2D(Device-to-Device，设备到设备)和V2X(Vehicle-to-Everything，车联网)受到越来越多的关注和研究。它可应用于公共安全、车联网、现场指挥、社交网络、电子支付、本地广告、游戏娱乐等。
D2D技术可以工作在有网络覆盖、部分网络覆盖和无覆盖等多种场景，允许多个支持D2D功能的用户设备(即D2D用户设备，D2D User Equipment，D2D UE)进行直接发现或者直接通信。D2D技术的应用，可以减轻蜂窝网络的负担、减少用户设备的电池功耗、提高数据速率，并改善网络基础设施的鲁棒性，很好地满足高数据速率业务和邻近服务的要求，并且也支持无网络覆盖场景下直接通信，可以满足公共安全等特殊通信需求。
车联网通信，是通过先进的无线通信技术，实现车与车、车与路侧基础设施、车与行人之间的实时信息交互，告知彼此目前的状态(包括车辆的位置、速度、加速度、行驶路径等)及获知的道路环境信息，协作感知 道路危险状况，及时提供多种碰撞预警信息，防止道路交通安全事故的发生。车联网通信的模式具体可分为几类：车与车通信(Vehicle-to-Vehicle Communication，简称为V2V)、车与人通信(Vehicle-to-Pedestrian Communications，简称为V2P)、车与网络基础设施通信(Vehicle-to-Infrastructure Communications，简称为V2I)，车与网络(Vehicle-to-Network Communications，简称为V2N)通信。上述的车联网通信模式也可以统称为车联网通信(Vehicle-to-Everything Communications，简称为V2X)。
D2D通信、V2X通信，或其他设备之间的直接通信，通常支持两种通信模式：模式一，基于基站调度的通信(称作Mode1)；模式二，UE自主选择资源的通信(称作Mode2)。为了支持低时延业务，需要发送UE尽快地将数据从空口发送出去。对于模式二，则需要发送UE选择出满足低时延要求的可用空闲的时频资源。

其中，所述配置信息包括至少以下之一：资源池类型，第一发送资源池列表，第一发送资源池索引，第二发送资源池列表，资源池的使用优先级，第二发送资源池索引；
或者，所述配置信息包括至少以下之一：
资源池类型，资源池的使用优先级，第二发送资源区域频域起始位置或索引，第二发送资源区域频域终止位置或索引，第二发送资源区域时域起始位置或索引，第二发送资源区域时域终止位置或索引，第二发送资源区域时域位置bitmap(位图)。
其中，资源池类型至少包括三种类型，如资源池类型一(第一种类型资源池)是作为基站调度分配资源的资源池；资源池类型二(第二种类型资源池)是作为UE自主选择的资源池；资源池类型三(第三种类型资源池)是既可以作为基站调度分配资源的资源池、可以作为UE自主选择的资源池。当然，资源池类型不限于以上所述，还可以为其它任何能够想到的合理方式。
其中，所述第一发送资源池、第二发送资源池、第三发送资源池，可以分别为一个资源池，也可以分别为一组资源池。所述第一发送资源池、第二发送资源池、第三发送资源池，可以在相同载波，也可以在不同载波。
在本发明的一可选实施例中，资源池的配置，有两种方案，分别如图2和图3所示。
方案一
如图2所示，包括第一发送资源池21和第二发送资源池22。
各资源池的配置信息可以由无线资源控制(RRC)信令携带，配置信息中指明当前资源池是否为第二发送资源池。配置信息中还可包括但不限于以下至少之一：
资源池类型，第二发送资源池列表，资源池的使用优先级，第二发送资源池索引，第一发送资源池列表，第一发送资源池索引，可用空闲资源的能量判决门限Th1，可用空闲资源数量或比例门限Th2。
方案二
如图3所示，包括第三发送资源池30，第三发送资源池30中包括第一发送资源区域31和第二发送资源区域32。
其中，可以通过RRC消息携带发送资源池的配置信息，该配置信息中同时会指示部分频域范围和/或时域范围内的资源为第二发送资源区域32，其余为第一发送资源区域31，或者指示部分频域范围和/或时域范围内的资源为第一发送资源区域31，其余为第二发送资源区域32。
RRC消息中还可携带包括但不限于至少以下之一：
资源池类型，资源池的使用优先级，第二发送资源区域频域起始位置或索引，第二发送资源区域频域终止位置或索引，第二发送资源区域时域起始位置或索引，第二发送资源区域时域终止位置或索引，第二发送资源区域时域位置bitmap(位图)，可用空闲资源的能量判决门限Th1，可用空闲资源的数量或比例门限Th2。
方案一是采用两个资源池，二者所包含的资源的时频位置可以连续，也可以不连续。即第一发送资源池位于一个时频区域，第二发送资源池与第一发送资源池之间可以间隔一些时频资源。也可以分别在不同的载波上。方案二是一个资源池，第一发送资源区域31和第二发送资源区域的时频资源是连续的。
其中，上述Th1、Th2可以为一个值，也可以为与CBR(信道占用率，Channel Busy Ratio)或PPPP(业务优先级，Prose Per Packet Priority)对应的一组值(多个值)。即一个或多个业务优先级，或一个或多个CBR等级，对应一个可用空闲资源的能量判决门限。其中，对于Th1，通常PPPP越高， 取值越小；CBR越高，取值越小。对于Th2，通常PPPP越高，取值越大；CBR越高，取值越大。
所述可用空闲资源数量或比例门限Th2可以预配置，或从基站处获取，或根据用户设备所需的最少资源量确定。
同样地，所述能量判决门限Th1可以预配置，或者，从基站处获取，或者，根据用户设备的需求而定。
应该理解，在具体实现上，可以为每个资源池(第一至第三资源池)各配置一个Th1和一个Th2，可以为所有资源池配置同一个Th1和同一个Th2，还可以为部分资源池配置同一个Th1和同一个Th2，其它资源池各自配置，也可以为每个UE配置一个Th1和一个Th2；除以上方式，本方案中的Th1、Th2的配置方式还涵盖有任何其它能够想到的合理方式，对此本方案不做一一阐述。
在本发明的一可选实施例中，所述第一发送资源池或者所述第一发送资源区域满足预设资源选择条件是指：所述第一发送资源池或者所述第一发送资源区域的可用空闲资源的数量大于或者大于等于可用空闲资源数量门限，和/或所述第一发送资源池或者所述第一发送资源区域的可用空闲资源的比例大于或者大于等于可用空闲资源比例门限Th2。
在本发明的一可选实施例中，所述可用空闲资源为所述第一发送资源池或所述第一发送资源区域中，在一定时域范围内(比如，资源选择窗口)内，经过资源检测，未被占用或预测未被占用，满足时延要求且其能量小于或小于等于能量判决门限Th1的资源。可用空闲资源中排除了可能已被或将被其他UE占用的资源，和/或由于半双工原因当前UE还未经过检测(sensing)的资源(无法确定是否被其他用户占用的资源)。
所述可用空闲资源的能量判决门限Th1是指，用于判断UE用于发送PSSCH(Physical Sidelink Share Channel，物理边链路共享信道)和/或PSCCH (Physical Sidelink Control Channel，物理边链路控制信道)资源上能量高低的门限。所述能量是指UE测量用于发送PSSCH和/或PSCCH的资源上S-RSSI(Sidelink-Received Signal Strength Indication，边链路的接收的信号强度指示)或DMRS(Demodulation Reference Signal，解调参考信号)的RSRP(Reference Signal Receiving Power，参考信号接收功率)。
其中，UE从第二发送资源池或第二发送资源区域选择满足要求的资源，至少需要满足以下条件之一：
UE有数据要发送，需要选择资源或重选资源；
UE sensing第一发送资源池或第一发送资源区域的可用空闲资源数量或比例低于或不高于至少可用空闲资源的门限Th2。
UE在选择资源之前，对第二发送资源池或第二发送资源区域进行了资源检测(sensing)。
可选地，UE从第二发送资源池或第二发送资源区域选择到满足要求的资源之后，可以在此资源上发送PSSCH和/或PSCCH。可只使用一次，也可按照SPS(Semi-Persistent Scheduling，半静态调度)进程连续使用多个发送周期的资源。
在本发明的另一可选实施例中，所述第一发送资源池或者所述第一发送资源区域满足预设资源选择条件是指：在所述第一发送资源池或者所述第一发送资源区域中，计算资源检测后的可用空闲资源集合中资源的能量统计值，且能量统计结果小于或小于等于能量判断门限。也就是说，针对资源为第一发送资源池、第二发送资源池(或者第一、二发送资源区域)的情形，对第一发送资源池(或者第一发送资源区域)的可用资源集合中资源的能量统计值进行计算，如果第一发送资源池(或者第一发送资源区域)的能量统计值小于或小于等于第一发送资源池(或者第一发送资源区域)的能量判断门限，则利用第一发送资源池(或者第一发送资源区域) 进行数据的发送。否则，利用第二发送资源池(或者第二发送资源区域)进行数据的发送。
在本发明的再一可选实施例中，所述第一发送资源池或者所述第一发送资源区域满足预设资源选择条件是：在所述第一发送资源池或者所述第一发送资源区域中，对第一发送资源池/第一发送资源区域的可用空闲资源集合进行能量统计得到的能量统计结果小于对第二发送资源池/第二发送资源区域的可用空闲资源集合进行能量统计得到的能量统计结果。
也即，针对所有的发送资源池(第一、二发送资源池)/资源区域(第一、二发送资源区域)，比较对各个发送资源池/资源区域的可用空闲资源集合进行能量统计的能量统计结果，选择能量统计结果最小的发送资源池/资源区域进行数据的发送。
下面以车联网通信(V2X)为例，通过几个优选的实施例来进一步说明上述的资源选择方法。
实施例一
该实施例提供了一种模式二UE进行资源选择的方法，基本流程如图4所示，详细步骤包括：
步骤401、接收基站发送的资源池的配置信息，资源池方案为图2所示的方案一。其中，第一发送资源池和第二发送资源池分别位于不同的载波。第一发送资源池的使用优先级高于第二发送资源池。
还可接收基站配置的其他参数，包括但不限于：可用空闲资源的能量判决门限Th1，可用空闲资源的比例或数量门限Th2，资源选择窗口。
步骤402、检测(sensing)第一发送资源池和/或第二发送资源池，并统计满足时延要求的可用空闲资源；
一种统计方法为：在待检测的资源池内，在一定的时间范围内，接收 或监听所有资源上的PSCCH和PSSCH信道，并测量资源上的能量或导频信号能量，并根据信号周期、占用资源大小、优先级等特征，预测资源选择窗口内的资源使用情况，排除可能已被其他UE占用的和/或由于半双工原因未经过sensing的资源，包括但不限于：
正确接收到用于指示当前数据(data)传输PSSCH的控制信令的调度分配(SA，Scheduling Assignment)/边链路控制信息(SCI，Sidelink Control Information)和data的资源位置；未正确接收但能量大于或大于等于可用空闲资源能量判决门限Th1的资源；由于当前时间上在发送数据而未能检测的资源；其他可能与其他UE使用资源有冲突的资源。
在排除以上资源后的剩余资源中，统计满足时延要求且能量小于或小于等于可用空闲资源能量判决门限Th1的资源数量或比例。
步骤403，如果有数据要发送，则执行步骤404，否则，执行步骤402；
步骤404、判断第一发送资源池是否满足资源选择条件，如果满足，则执行步骤405；否则，执行步骤406；
其中，一种判断方法是：将资源选择窗口内可用空闲资源的比例或数量与空闲资源的比例或数量门限Th2进行比较，如果可用空闲资源比例或数量大于等于或大于门限Th2，则第一发送资源池满足资源选择条件，否则，不满足资源选择条件。所述门限Th2，可以是与资源池对应的一个值；或为与资源池无关的一个值；或为与业务优先级对应的一组值，优先级越高，Th2越大；或为与资源池的资源占用率对应的一组值，资源占用率越高，门限越大。此处，由于信道可视为一种资源，对于Th2，“CBR越高，取值越大”可视为“资源占用率越高，门限越大”的一种具体实现情况。
上述方案中，所描述的门限Th2可以是与资源池对应的一个值或为与资源池无关的一个值的含义，可以这样理解：可以为每个资源池(第一至第三资源池)各配置一个Th2，或为所有资源池配置同一个Th2，或为部分 资源池配置同一个Th2、其它资源池各自配置等等。
步骤405，在第一发送资源池内选择资源并发送数据，结束；
步骤406，在第二发送资源池内选择资源并发送数据，结束。
例如，假定空闲资源数量门限Th2为20，检测到资源选择窗口内可用空闲资源为30，检测到的资源选择窗口内的可用空闲资源的数量30大于数量门限20，则使用第一发送资源池发送数据；
假定空闲资源比例门限Th2为20％，假定总资源数量为100，则计算得到可用空闲资源数量门限为100*20％＝20，与可用空闲资源的数量30比较，实际检测的数量大于门限，则使用第一资源池发送数据；
假定空闲资源比例门限Th2为20％，实际检测的数量为30，总的资源数量为100，则实际检测的可用空闲资源比例为30％，与比例门限Th2做比较，实际检测的数量比例大于比例门限，则使用第一资源池发送数据。
其中，如果UE发送SPS业务，UE可持续占用选择的资源发送数据，直到下一次资源重选时间的到来。但如果当前使用的是第二发送资源池或第二发送资源区域，也可以在每次发送数据前，执行步骤404，监测第一发送资源池是否满足资源选择条件，如果满足资源选择条件，则在第一发送资源池中重新选择资源并进行后续的数据发送。
其中，模式二UE可以与legacy UE和/或模式一UE共享使用第一发送资源池。
该实施例，经过上述的资源选择过程，UE在第一发送资源池中无法获得满足资源选择条件的资源时，通过在第二发送资源池上选择/重选资源，获得满足时延要求的可用资源，保证了低时延业务的发送。
实施例二
该实施例提供了一种资源选择方法，如图5所示，包括：
步骤501，预配置或从基站接收资源池的配置信息，资源池方案为图3 所示的方案二。还可接收基站配置的其他参数，包括但不限于：可用空闲资源的能量判决门限Th1，可用空闲资源的比例或数量门限Th2，资源选择窗口。
步骤502，检测第一发送资源区域和/或第二发送资源区域内满足时延要求的可用空闲资源；
步骤503，如果有数据要发送，则继续步骤504，否则，执行步骤502；
步骤504，判断第一发送资源区域是否满足资源选择条件，如果满足，则执行步骤505；否则，执行步骤506；
其中，一种判断方法是：将资源选择窗口内可用空闲资源的比例或数量与空闲资源的比例或数量门限Th2进行比较，如果可用空闲资源比例或数量大于等于或大于门限Th2，则第一发送资源区域满足资源选择条件，否则，不满足资源选择条件。
步骤505，在第一发送资源区域内选择资源并发送数据，结束；
步骤506，在第二发送资源区域内选择资源并发送数据，结束。
其中，如果UE发送SPS业务，UE可持续占用选择的资源发送数据，直到下一次资源重选时间的到来。但如果当前使用的是第二发送资源区域，也可以在每次发送数据前，执行步骤504，监测第一发送资源区域是否满足资源选择条件，如果满足，则可在第一发送资源区域中重新选择可用的资源进行后续的数据发送。
其中，第一发送资源区域，可配置为legacy模式二UE的发送资源池，由模式二UE与legacy UE共享使用，也可以与模式一UE共享使用。
该实施例，经过上述的资源选择过程，UE在第一发送资源区域中无法获得可用资源时，可通过在第二发送资源区域上选择资源，获得满足时延要求的可用资源，保证了低时延业务的发送。
实施例三
该实施例提供了一种资源选择方法，如图8所示，所述方法包括：
步骤801，UE预配置或从基站接收资源池的配置信息，包含一个或多个发送资源池。如图2所示，包含2个发送资源池即第一发送资源池和第二发送资源池。
步骤802，UE检测第一发送资源池和/或第二发送资源池内满足时延要求的可用空闲资源，作为对应资源池的可用空闲资源集合，对每个发送资源池的可用空闲资源集合进行能量统计，得到每个发送资源池的能量统计结果；
此处，针对每个发送资源池，之所以是各个发送资源池的集合，主要考虑到，各个发送资源池中可能会存在资源不连续的(可用)空闲资源，如频域和/或时域位置不连续的空闲资源。如果发送资源池中存在资源不连续的空闲资源，则可将所有资源不连续的空闲资源进行集合形成可用空闲资源集合。如果发送资源池中不存在资源不连续的空闲资源即存在资源连续的空闲资源，无需将这段资源连续的空闲资源视为可用空闲资源的集合，视为一段资源连续的可用空闲资源即可。
所述可用空闲资源为所述各个发送资源池中，在一定时域范围内，经过资源检测，未被占用或预测未被占用，满足时延要求的一定数量的资源。所述一定数量为预定义、预配置或系统配置的一个数量值，或为预定义、预配置或系统配置一个数量比例值，该数量比例指的是各个发送资源池的可用空闲资源集合与对应发送资源池中资源总量的比值。
步骤803，将所述可用空闲资源集合和能量统计结果上报用户设备的高层。
此处，本领域人员应该而知，国际标准化组织(ISO)定义了开放式系统互联参考模型(OSI，Open System Interconnection)，OSI模型把网络通信的工作分为7层，从底层开始依次是物理层、数据链路层、网络层、传输 层、会话层、表示层和应用层。高层的概念是相对而言的，比如，媒体介入控制层(MAC，Media Access Control)，属于OSI模型中数据链路层，通常将位于MAC层以上的层视为高层。高层还可以指代的是会话层、表示层和应用层这三层。高层还可以指代是七层中的除了物理层之外的其它层。当然，高层的概念还可以包括其它任何能够想到的合理方式，此处不做具体限定。具体的高层指的是哪种含义根据实际应用场景而定。
步骤804，UE的高层做资源选择时，根据对预设资源选择条件的判断结果选择对应的资源池。
如果经判断满足预设资源选择条件的发送资源池为第一发送资源池，则执行步骤805；
否则，执行步骤806。
其中，所述一种预设资源选择条件是：针对第一、二发送资源池中的其中一个发送资源池如第一发送资源池，比较该发送资源池的对空闲资源集合进行能量统计的能量统计结果与为该资源池预先配置/定义的能量判决门限Th1之间的大小关系，当判断为对空闲资源集合进行能量统计的能量统计结果小于或小于等于能量判决门限Th1，则选择该发送资源池(第一发送资源池)。否则，继续判断其他发送资源池或选择异常资源池。
所述另一种预设资源选择条件是：针对所有的发送资源池，比较对各个发送资源池的可用空闲资源集合进行能量统计的能量统计结果，选择能量统计结果最小的发送资源池。
所述能量统计结果为统计所述可用空闲资源集合中各资源单元的能量值的最大值、平均值、或方差。所述能量值可以为以下之一：各资源单元的信号接收功率(S-RSSI，Sidelink Received Signal Strength Indicator)，共享信道导频接收功率(PSSCH-RSRP，PSSCH Reference Signal Received Power)，控制信道导频接收功率(PSCCH-RSRP，PSCCH Reference Signal  Received Power)。
步骤805，在第一发送资源池内选择资源并发送数据，流程结束；
步骤806，在第二发送资源池内选择资源并发送数据，流程结束。
需要说明的是，本实施例中，是以资源为第一、二发送资源池为例进行的说明，如果资源是第三发送资源池中的第一发送资源区域和第二发送资源区域，则执行过程与前述的方案类似，此处不赘述。
在本实施例中，经过上述的资源选择过程，如果UE在第一发送资源池/区域中无法获得可用空闲资源时，可在第二发送资源池/区域上选择资源并发送数据，由此UE能够获得满足时延要求的可用空闲资源，保证了低时延业务的发送。
实施例四

在本发明的一可选实施例中，所述方法还包括：将所述可用空闲资源数量或比例门限、能量判决门限至少之一发送给所述用户设备。
