Description

资源优先级的确定方法、处理装置及系统、UE 技术领域
本申请涉及但不限于通信领域，尤其涉及一种资源优先级的确定方法、处理装置及系统、用户设备(UE，User Equipment)。
背景技术
在相关技术的设备到设备(Device-to-Device，简称为D2D)通信系统中，用户设备(User Equipment，简称为UE)之间有业务需要传输时，UE之间的业务数据不经过基站的转发，而是直接由数据源UE通过空中接口传输给目标UE，如图1所示，D2D UE之间的无线链路称为边链路(Sidelink)，D2D通信模式具有明显区别于传统蜂窝系统通信模式的特征，对于能够应用D2D通信方式的近距离通信用户来说，D2D传输不但节省了无线频谱资源，而且降低了核心网的数据传输压力，能够减少系统资源占用，增加蜂窝通信系统频谱效率，降低终端发射功耗，并在很大程度上节省网络运营成本。
在相关技术的蜂窝通信系统中，UE的无线资源由演进型基站(eNB，evolved NodeB)统一控制调度，eNB指示UE所配置的下行或上行资源，UE按照eNB的配置指示在相应的下行资源上接收eNB发射的数据信号，或者在上行资源上向eNB发射信号。在长期演进(LTE，Long Term Evolution)系统中，eNB可以灵活地根据UE需求动态调度配置所需的资源。
在D2D通信系统中，UE之间直接进行数据的传输，发送端UE可以按照网络侧的调度配置获得D2D通信的物理边链路控制信道(PSCCH，Physical Sidelink Control Channel)和物理边链路共享信道(PSSCH，Physical Sidelink Shared Channel)资源，也可以在给定的PSCCH和PSSCH资源池中竞争选择资源进行D2D通信控制及数据信息的发射。
车联网系统是指通过装载在车辆上的传感器、车载终端及电子标签等设备提供车辆信息，采用各种通信技术实现车与车(Vehicle-to-Vehicle，简称为V2V)、车与人(V2P，Vehicle-to-Person)、车与基础设施(V2I，Vehicle-to-Infrastructure)之间的互连互通，并在信息网络平台上对信息进行 提取、共享等有效利用，对车辆进行有效的管控和提供综合服务的系统。车联网可以实现基于通信的车辆信息通知及碰撞危险预警，通过利用先进的无线通信技术和新一代信息处理技术，实现车与车、车与路侧基础设施间的实时信息交互，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)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，成为当前解决道路交通安全问题的一种新的思路。
近年来，随着新的移动通信技术的发展，基于长期演进(LTE，Long Term Evolution)技术来解决车联网通信是热点研究之一。其中，车与车之间的近距离通信可以应用D2D通信方式，作为D2D通信方式的一种特殊应用。
但在相关技术中上述D2D/V2V通信过程中存在以下问题：eNB为UE调度Sidelink资源，或者UE在Sidelink资源池中选择资源时，由于缺乏对Sidelink资源使用情况的信息，影响了资源调度选择的有效性，使Sidelink资源的使用效率较低。
针对相关技术中存在的上述问题，目前尚未发现有效的解决方案。

UE在PSCCH资源池中，通过对每一个PSCCH资源进行能量检测和解码中的至少一项，判定此PSCCH资源的优先级，体现为优先级指数或者优先级等级。基于对PSCCH资源池中每个PSCCH资源的优先级判定，UE可以进行PSCCH资源选择，或者将部分或全部的PSCCH资源优先级信息上报给eNB，供eNB进行PSCCH资源调度参考。
根据对PSCCH资源进行能量检测和信息解码中的至少一项，确定PSCCH资源优先级的方法包括两类，图9是本发明实施例中方法一确定PSCCH资源优先级的过程示意图；图10是本发明实施例中方法二确定PSCCH资源优先级的过程示意图。
方法一、加权处理
如图9所示，本实施例中方法一确定PSCCH资源优先级的过程包括：
S902、对PSCCH资源进行能量检测和信息解码中的至少一项，获得检测结果和解码结果中的至少一项；其中，对PSCCH资源进行能量检测，获得能量值或功率值，作为检测结果；对PSCCH资源上承载的SCI信息进行解码，确定解码正确或错误，作为解码结果。

S906、基于权值处理规则，根据PSCCH资源的能量加权值和解码加权值中至少一项，确定PSCCH资源的优先级指数或者优先级等级。
方法二、查表
如图10所示，本实施例中方法二确定PSCCH资源优先级的过程包括：
S1002、对PSCCH资源进行能量检测和信息解码中的至少一项，获得检测结果和解码结果中的至少一项；
S1004、根据第一优先级等级表，确定PSCCH资源的优先级。
在本方法中，系统预定义或高层信令配置第一优先级等级表，根据对PSCCH资源的能量检测和信息解码结果中的至少一项，可查表唯一确定对应的PSCCH优先级等级。
不论方法一还是方法二，都需要对PSCCH资源执行以下至少一项处理：进行能量检测、信息解码处理。
其中，对PSCCH资源进行能量检测的方法可以包括：
对PSCCH资源上的导频资源单元(RE，Resource Element)进行能量检测，获得导频能量值或者导频功率值；或者，
对PSCCH资源上的所有RE进行能量检测，获得PSCCH资源的总能量值或者总功率值；

对PSCCH资源进行信息解码的方法可以包括：对PSCCH资源进行接收解码，按照所承载的SCI格式进行校验，通过校验判定解码结果为正确或者错误，获得此PSCCH资源上的信息解码结果。
然后，根据PSCCH资源的能量检测和信息解码中至少一项的结果按照方法一或方法二确定相应的优先级。
基于方法一，需对上述PSCCH资源的能量检测结果和信息解码结果中的至少一项进行加权处理，其中，加权处理方法可以包括以下至少之一：
根据对PSCCH资源进行能量检测获得的能量值或功率值，按照第一对应关系确定对应的加权值，其中，第一对应关系定义了PSCCH资源的能量值或功率值的数值对应的能量加权值；
根据对PSCCH资源进行的信息解码的结果，按照第二对应关系确定对应的解码加权值，其中，第二对应关系定义了所述信息解码结果正确对应的加权值以及信息解码结果错误对应的加权值。
在示例实施方式中，对PSCCH资源的能量加权值和解码加权值中的至少一项按照权值处理规则进行处理，可以确定PSCCH资源的优先级，这里 PSCCH资源的优先级体现为优先级指数，或优先级等级。
在示例性实施方式中，对PSCCH资源的能量加权值和解码加权值中的至少一项进行处理的权值处理规则可以是：将PSCCH的能量加权值和解码加权值中的至少一项进行线性运算，确定PSCCH资源的优先级。
其中，权值处理规则可以包括但不限于下列方法：
将PSCCH的能量加权值与解码加权值相加，确定PSCCH资源的优先级指数；
将所述PSCCH的能量加权值与解码加权值分别乘以相应的权重系数后再相加，确定PSCCH资源的优先级指数；
将PSCCH的能量加权值与解码加权值相乘，确定PSCCH资源的优先级指数。
在示例性实施方式中，根据获得的PSCCH资源的优先级指数，基于优先级指数等级换算表，可以将优先级指数转换为优先级等级。优先级指数等级换算表定义了任意优先级指数唯一对应的优先级等级。如此，PSCCH资源的优先级指数可折算为相应的优先级等级。
在示例性实施方式中，权值处理规则可以是按照第二优先级等级表，根据PSCCH的能量加权值和解码加权值中的至少一项，确定PSCCH资源的优先级，其中，第二优先级等级表定义了任意能量加权值和解码加权值中至少一项唯一对应的优先级等级。
基于方法二，需对上述PSCCH资源的能量检测结果和信息解码结果中至少一项进行查表处理，其中，查表处理方法可以包括：
根据对PSSCH资源的能量检测和信息解码中至少一项的结果，根据第一优先级等级表进行查表，则可唯一确定此PSCCH资源的优先级等级；其中，第一优先级等级表中定义了任意的能量检测结果和信息解码结果中至少一项对应的PSCCH资源优先级等级。
在方法一或方法二中，可以通过系统预定义或者由网络侧通过高层信令配置指示下列一项或多项：第一优先级等级表；第一对应关系；第二对应关系；权值处理规则；优先级指数等级换算表；第二优先级等级表。
上述确定PSCCH资源优先级的方法在不冲突的条件下可以任意组合使用。对多个PSCCH资源的优先级确定，可以形成PSCCH资源优先级列表，其中，PSCCH资源的优先级列表可以作为网络侧为UE调度配置PSCCH资源的参考信息，或者作为UE自身竞争或选择PSCCH资源的依据。
网络侧可以包括以下实体中的一种或多种：演进型基站(eNB)、中继站(RN)、小区协作实体(MCE)、网关(GW)、移动性管理设备(MME)、演进型通用陆地无线接入网(EUTRAN)操作管理及维护(OAM)管理器。
下面以eNB作为网络侧实体为例进行说明。

其中，根据测量所得的功率值或能量值，按照系统预定义的第一对应关系，确定PSCCH资源的能量加权值。
一种第一对应关系的实例如表1所示。UE测量PSCCH资源上的导频功率为E，则根据下表可确定相应的能量加权值k。

… … …
n En-1≤E<En kn
… … …
N EN-1≤E kN
实例二
UE对每个PSCCH资源进行SCI信息盲检，判断是否承载了有效的SCI信息，当解码校验正确，则在此PSCCH资源上获得了SCI信息，否则即为解码错误。一种第二对应关系的实例如表2所示。UE盲检PSCCH资源上SCI信息，当解码正确时，相应的解码加权值为s0；解码错误，未获得SCI信息时，则相应的解码加权值为s1。
表2
index 信息解码 加权值s
0 正确 s0
1 错误 s1
实例三
UE对某PSCCH资源进行能量检测及信息解码后，能量加权值为k2，解码加权值为s0，则根据权值处理规则，确定此PSCCH资源的优先级指数P。
其中：当系统预定义的权值处理规则为将PSCCH资源的能量加权值与解码加权值相加，则此PSCCH资源的优先级指数为：P＝k2+s0；
当系统预定义的权值处理规则为将PSCCH资源的能量加权值与解码加权值分别乘以相应的权重系数后相加，且定义了能量加权值的权重系数为K，解码加权值的权重系数为S，则此PSCCH资源的优先级指数为：
P＝K*k2+S*s0；
当系统通过高层信令指示采用的权值处理规则为将PSCCH的能量加权值与解码加权值相乘，则此PSCCH资源的优先级指数为：P＝k2*s0。
UE根据系统采用的权值处理规则，按照对PSCCH资源的能量检测和信息解码中至少一项的结果，可确定相应的PSCCH资源的优先级指数。
实例四
根据能量加权值和解码加权值中至少一项通过权值处理规则确定的PSCCH资源的优先级指数可以提供较精细的优先级信息，考虑到进一步的资源选择或者资源优先级信息上报，PSCCH资源的优先级可以做进一步的转化， 将精细的优先级指数P转换为优先级等级R，即定义优先级指数到优先级等级的对应关系表。一种优先级指数等级换算表的实例如表3所示。

其中，r0、r1、…、r2N+1指优先级等级。
