Description

一种资源分配方法及设备
本申请要求在2017年3月24日提交中国专利局、申请号为201710184471.6、发明名称为“一种资源分配方法及设备”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
本发明涉及通信技术领域,特别涉及一种资源分配方法及设备。
背景技术
目前,车辆通信是指在车辆上装载可以进行移动通信的用户设备(User Equipment,UE)之后,车辆可以通过该用户设备无线接入车辆通信网络,进而与其他用户设备进行通信。车辆可以发送道路安全消息给其他用户设备,道路安全消息可以包括车辆自身的状态或者附近道路的状态等等这些与道路行驶安全相关的信息,其他用户设备接收到道路安全消息之后,则可以根据该状态做出相应的处理。例如,若是一辆正在行驶的车辆突然发生了紧急故障,则该车辆可以将故障状态信息发送给附近的车辆上安装的用户设备或行人的用户设备,使得附近的车辆或行人能够及时的避让,从而保证道路交通安全。
在车辆通信中,若车辆需要发送道路安全消息给其他用户设备时,则需要通过发送资源来发送。而现在的发送资源分配模式有两种,即分配模式(mode)3和分配模式(mode)4。其中,这两种分配模式的发送资源池都是由演进基站(evolved Node B,eNB)来分配的,但是采用mode3的用户设备的发送资源是由其附近的eNB来分配的;而采用mode4的用户设备的发送资源是由其自己从对应的发送资源池中选择的,为避免在资源分配时发生干扰,因此目前采用mode3的用户设备的发送资源池和采用mode4的用户设备的发送资源池是相互独立的。但也因此可能出现这样的情况,可能采用mode3的 用户设备的发送资源池已经发生了拥塞,也就是说该发送资源池中的发送资源已经被占用了很大比例,例如已经被占用了80%;而采用mode3的用户设备的发送资源池中的发送资源都还很空闲。在这种情况时,eNB是可以对两个发送资源池进行一定的调整的,但是这种调整会使得通信中断,显然不利于通信的稳定性。因此如何合理提高发送资源的利用率,是目前亟待解决的,而其中一种方法即是将发送资源池1和发送资源池2中的发送资源进行共享。
若是将采用mode3的用户设备和采用mode4的用户设备的发送资源池进行共享,因为采用mode4的用户设备的发送资源由于是由其自己选择的,因此将发送资源池进行共享对于采用mode4的用户设备来讲,其实并未有什么影响。但是对于采用mode3的用户设备来讲,由于其的发送资源是由eNB来分配的,而eNB只知道自己给采用mode3的用户设备分配过哪些发送资源,但并不知道采用mode4的用户设备占用了哪些发送资源,因此在给采用mode3的用户设备分配发送资源时,有可能将采用mode4的用户设备已经占用的发送资源分配给采用mode3的用户设备,进而采用mode3的用户设备和采用mode4的用户设备使用的发送资源则会发生冲突,这样显然是不可行的。

附图说明
图1为本发明实施例提供的本发明实施例的应用场景图;
图2为本发明实施例提供的资源分配方法的流程图;
图3为本发明实施例提供的资源分配设备的一种结构示意图。
具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述。
以下,对本发明实施例中的部分用语进行解释说明,以便于本领域技术人员理解。
用户设备,是指可以向用户提供数据连通性的设备,该设备可以通过无线接入网(Radio Access Network,RAN)与其他用户设备进行通信,例如都可以通过车载的移动装置等设备实现。当然,用户设备还可以是包括可以进行无线通信设备的设备,本发明实施例对此不做限制。
另外,本文中出现的术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存 在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
首先介绍本发明实施例的一种应用场景,请参见图1。其中,mode3 UE即是指采用mode3的用户设备,mode4 UE即是指采用mode4的用户设备。发送资源池1为eNB为mode3 UE分配的发送资源池,发送资源池2为eNB为mode4分配的发送资源池。UEmode3 UE可以向其他mode3 UE或者mode4 UE发送道路安全消息,mode4 UE也可以向其他mode4 UE或者mode3 UE发送道路安全消息。在mode3 UE要发送道路安全消息时,mode3 UE需要向向eNB发起发送资源请求,该发送资源请求用于告知eNB此时mode3 UE需要发送道路安全消息以及mode3 UE发送该道路安全消息需要的发送资源,则eNB会根据该发送资源请求给mode3 UE分配发送资源池1中处于空闲状态的发送资源。而在mode4 UE要发送道路安全消息时,mode4 UE则可以根据mode4 UE接收到的其他UE发送来的道路安全消息可以知道发送资源池2中的哪些发送资源已经被占用,则mode4 UE会在发送资源池2中剩余的处于空闲状态的发送资源中选择发送资源。
目前发送资源池1和发送资源池2是完全相互独立的,发明人在发明过程中注意到,也因此可能出现这样的情况,可能发送资源池1已经发生了拥塞,而发送资源池2中的发送资源都有空闲。因此如何提高发送资源的合理利用率,是目前亟待解决的,其中一种方法即是将发送资源池1和发送资源池2中的发送资源进行共享。
若是将发送资源池1和发送资源池2中的发送资源进行共享,因为mode4 UE的发送资源是由其自己选择的,因此将发送资源池进行共享对于mode4 UE来讲,其实并未有什么影响。但是对于mode3 UE来讲,由于mode3 UE的发送资源是由eNB来分配的,而eNB只知道自己给mode3 UE分配过哪些发送资源,但并不知道mode4 UE占用了哪些发送资源,因此在给mode3 UE分配发送资源时,有可能将mode4 UE已经占用的发送资源分配给mode3 UE,进而mode3 UE和mode4 UE使用的发送资源则会发生冲突,这样显然是不可行 的。
鉴于此,本发明实施例提供一种资源分配方案,该方案在基站给mode3 UE分配发送资源之前,基站首先会确定共享发送资源池中的哪些资源为可用资源,然后根据这些可用资源来为mode3 UE分配发送资源,这样也就可以避免将mode4 UE已经占用的发送资源分配给mode3 UE,进而也就避免了mode3 UE和mode4 UE的发送资源发生冲突。
下面结合附图介绍本发明实施例提供的技术方案。在下面的介绍过程中,可以将本发明实施例提供的技术方案应用在图1所示的应用场景为例,当然本发明实施例的应用场景不限于此。
请参见图2,本发明一实施例提供一种资源分配方法,该方法包括:
步骤201:基站确定第一模式用户设备及第二模式用户设备共享的共享发送资源池中是否包括可用资源;其中,第一模式用户设备的发送资源由基站分配;第二模式用户设备的发送资源由其从共享发送资源池内选择;
步骤202:若基站确定共享发送资源池中包括可用资源,则基站基于可用资源,给第一模式用户设备分配发送资源。
本发明实施例中,第一模式用户设备则可以是mode3 UE,第二模式设备则可以是mode4 UE。
本发明实施例中,在基站确定第一模式用户设备及第二模式用户设备共享的共享发送资源池中是否包括可用资源之前,基站还可以接收外部设备发送的资源状态信息。具体,这些外部设备可以包括第一模式用户设备和/或第二模式用户设备,当然,也可能包括其他可能的设备,本发明实施例对此不做限制。
本发明实施例中,在基站接收第一模式用户设备及第二模式用户设备发送的资源状态信息之前,基站可以从基站覆盖范围内用户设备中确定需要向基站发送资源状态信息的第一模式用户设备和/或所述第二模式用户设备。
具体的,需要向基站发送资源状态信息的第一模式用户设备和/或所述第二模式用户设备可以是基站预先设置好的,也就是说,可以在在基站中设置 要求这些第一模式用户设备和/或所述第二模式用户设备中哪些设备向基站发送资源状态信息。例如基站可以预先设置只要求基站覆盖范围内的第一模式用户设备发送资源状态信息;或者基站可以设置只要求基站覆盖范围内的第二模式用户设备发送资源状态信息;当然,基站也可以设置要求基站覆盖范围内的所有的第一模式用户设备和第二模式用户设备都发送资源状态信息。
在下文中将第一模式用户设备和/或第二模式用户设备简称为用户设备,下文中所提到的用户设备即是包括第一模式用户设备和/或第二模式用户设备,在下文中将不再进行解释。
在实际应用中,因为用户设备在向基站发送资源状态消息时,与其他用户设备进行通信所占用的信道是相同的,若是同时向基站发送资源状态信息的数量过多,则有可能影响到其他设备的通信过程。因此,基站可以要求部分的用户设备发送资源状态信息。具体的,基站可以估算需要向基站发送资源信息的用户设备和用户设备的比例,这里的比例可以以不影响其他设备的通信过程为基准来估算。在基站确定需要需要向基站发送资源信息的第一模式用户设备和第二模式用户设备的比例之后,基站则可以在基站覆盖范围内选择这个比例对应数量的用户设备。另外,基站在选择用户设备时,还可以考虑地理位置因素。也即,基站在选择用户设备时,尽量使得选择的用户设备包括各个方位的用户设备,这样基站接收到的资源状态信息会比较全面准确。
本发明实施例中,基站在确定需要向基站发送资源状态信息的用户设备,也就是在基站确定了需要向基站发送资源状态信息的第一模式用户设备和/或第二模式用户设备之后,基站可以给这些用户设备发送第一指示消息,第一指示消息用于指示这些用户设备向基站发送所述资源状态信息。
本发明实施例中,在用户设备接收到第一指示消息之后,用户设备则会将收集到的资源状态信息发送给基站。
在实际应用中,用户设备除了可以给其他用户设备发送道路安全消息信息之外,还可以接收其他用户设备发送来的道路安全消息,该道路安全消息 除了包括关于道路安全消息的数据外,还可以包括用于指示发送该道路安全消息的用户设备所占用的发送资源的位置信息,也就是SA。在用户设备接收到道路安全消息后,可对SA进行解码,若SA成功被解码,则SA所指示的位置的发送资源则是被占用的,也就是说该SA所指示的位置的资源为不可用资源,相对应的,若是发送资源处于的位置不是成功解码后的SA所指示的位置,则可以确定该发送资源没有被占用,也就是说该发送资源是可用资源。
进一步地,用户设备在对SA成功解码后,用户设备还可以测量SA的功率值,并根据SA的测量功率值确定该SA所指示的位置的发送资源是否为可用资源。因为可能出现这样的情况,发送资源的位置有可能被成功解码的SA所指示,但是这个SA的测量功率值很小,则相应的,包括这个SA的道路安全消息的信号强度也是十分弱的,则可以认为SA所指示的位置没有被占用,也就是说,当SA的功率测量值不大于预设功率测量值时,则认为该SA所指示的位置对应的发送资源是可用资源。
另外,在用户设备接收到第一指示消息之后,用户设备还可以对共享发送资源池中的发送资源进行测量,则用户设备可以根据测量的发送资源的功率测量值确定发送资源的状态。具体的,若是用户设备测量的发送资源的功率测量值大于预设的功率测量值,则说明有用户设备正在通过该发送资源发送道路安全消息,也就是说明该发送资源正在被占用;若是用户设备测量的发送资源的功率测量值不大于预设的功率测量值时,也就是说有可能有用户设备正在通过该发送资源发送道路安全消息,但由于该功率测量值很小,则即使有用户设备在发送道路安全消息,这个道路安全消息的信号强度也是十分弱的,则可以认为该用户设备没有占用该发送资源,也就是说,当用户设备测量的发送资源的功率测量值不大于预设功率测量值时,则认为该发送资源是可用资源。
进一步地,用户设备测量的发送资源的功率测量值可以是参考信号接收功率(Reference Signal Receiving Power,RSRP),当用户设备测量的的RSRP值不大于预设RSRP值时,则认为该RSRP值对应的发送资源为可用资源,否 则相反。其中,预设RSRP值可以是用户设备预先设置好的,也可以根据发送资源的不同将RSRP值设为不同的值,当然,也可以是用户设备根据基站发送的预设RSRP值进行设置的。
本发明实施例中,用户设备在测量获得功率测量值之后,还可以将测量获得的功率测量值发送给基站,则基站也可以根据功率测量值是否不大于预设功率测量值确定该发送资源是否是可用资源。其中,这里的预设功率测量值可以是基站预先设置好的,并且该预设功率测量值可以跟用户设备设置的预设功率测量值相同,也可以不相同。
本发明实施例中,用户设备可以根据上述的三种确定方式的一种或多种来进行来确定发送资源是否为可用资源。具体的,三种确定方式即:根据发送资源的位置是否是被任何一个成功解码的SA指示的位置、SA的功率测量值是否不大于预设功率测量值以及发送资源的功率测量值是否不大于预设功率测量值。
本发明实施例中,在用户设备确定发送资源是否为可用资源之后,则可以根据确定的结果生成资源状态信息。其中,这个资源状态信息可以是过去资源的资源状态信息,也可以是未来资源的资源状态信息。过去资源即是指该用户设备发送资源状态信息的时刻之前的发送资源的状态信息,未来资源即是指该用户设备发送资源状态信息的时刻之后的发送资源的状态信息。未来资源的资源状态信息可以根据用户设备获取的之前的发送资源的持续时间和/或周期来进行推算,当然,在用户设备发送的资源状态信息中,也可以将发送资源的持续时间和/或周期也包括进去。另外,资源状态信息中还可以包括优先级信息,例如包括道路安全消息包括的数据的优先级信息或者用户设备的优先级信息。
在基站要求该用户设备发送资源状态信息时,用户设备则可以将生成的资源状态信息发送给基站。具体的,该用户设备发送的资源状态信息可以是包括该用户设备所知道的可用资源的状态信息,和/或该用户设备根据已经被占用的发送资源的状态信息确定的其余不可用资源的状态信息。当然,用户 设备发送的资源状态信息也可以包括该用户设备自己占用的发送资源的状态信息,并且用户设备还可以将自己占用的发送资源的位置进行指示,使得基站接收到资源状态信息后则可以知道该用户设备占用的发送资源的位置。或者,用户设备发送的资源状态信息还可以只包括该用户设备的占用的发送资源的信息。
在实际应用中,用户设备发送的资源状态信息可以是该用户设备已知的资源状态信息的全部,也可以是该用户设备已知的资源状态信息中的部分。若是用户设备将已知的资源的状态信息中的部分发送给基站,那么发送给基站的这部分资源状态信息可以是从全部的资源状态信息中随机选择的,也可以是该用户设备按照预定规则从全部的资源状态信息中选取的。例如,若是该用户设备发送给基站的资源状态信息是该用户设备确定的可用资源的信息,那么按预定规则则可以按照这些可用资源的空闲程度来进行排序,并选择出其中空闲程度较高的发送资源,并将这些空闲程度较高的发送资源的资源状态信息发送给基站。具体的,发送资源的空闲程度可以根据测量得到的发送资源的接收总功率(Received Signal Strength Indication,RSSI)来确定,RSSI值越小,则对应的发送资源越空闲。
本发明实施例中,因为发送资源存在级别关系,例如,发送资源可以是子帧级别的,一个子帧又可以包括多个子信道,则发送资源也可以是子信道级别的,另外,将多个子信道进行不同方式的组合又可以构成多个子信道集合,则发送资源还可以是子信道集合级别的,因此用户设备发送给基站的资源状态信息可以是多种级别的发送资源的资源状态信息。具体的,可以包括但不限于以下三种:
用于表征子信道级别的发送资源的状态的资源状态信息;和/或,
用于表征子信道集合级别的发送资源的状态的资源状态信息;和/或,
用于表征子帧级别的发送资源的状态的资源状态信息;
具体的,子信道级别的资源状态信息可以表征具体的子信道的状态;子信道集合级别的资源状态信息可以表征子信道集合的状态,也就是说,若表 明该子信道集合的状态为可用资源,则认为该子信道集合包括的所有子信道的状态都为可用资源;子帧级别的资源状态信息可以表征子帧的状态,也就是说,若表明该子帧的状态为可用资源,则认为该子帧包括的所有子信道的状态都为可用资源。
其中,还存在两种特殊的情况,当子信道集合级别的资源状态信息中所有的子信道都被占用时,则子信道集合级别的资源状态信息即是相当于子帧级别的资源状态信息;当子信道集合级别的资源状态信息中只有一个子信道被占用时,则子信道集合级别的资源状态信息即是相当于子信道级别的资源状态信息。
具体的,在用户设备发送资源状态信息给基站时,还可以在资源状态信息中包括用于指示资源状态信息的级别的信息,使得基站可以知道用户设备发送的资源状态信息是哪种级别的。
本发明实施例中,用户设备可以通过无线资源控制信令(Radio Resource Control,RRC)将资源状态信息发送给基站。
本发明实施例中,用户设备还可以通过多种方式向基站发送资源状态信息。具体的,至少包括但不限于以下两种:
用户设备可以通过bitmap的方式向基站发送资源状态信息;或者,
用户设备发送的资源状态信息可以是用于指示发送资源在时频频域中的位置的资源位置信息。
具体的,在用户设备发送资源状态信息给基站时,还可以在资源状态信息中包括用于指示用户设备的发送方式的信息,使得基站可以知道用户设备是通过哪种方式进行发送的,进而可以进行后续的处理。
本发明实施例中,为了限制用户设备发送的资源状态信息过多,影响到其他通信设备的通信过程,因此可以限制用户设备发送的资源状态信息的所占用的子信道的数量,也就是限制用户设备发送的资源状态信息的bit位。下面将具体介绍资源状态信息的计算,以下的计算是以假设共享发送资源池中的发送资源总共包括1000个子帧,每个子帧包括10个子信道为例进行的。
具体的,若用户设备采用bitmap的方式向基站发送资源状态信息,则可以在一个bit位上的0表示该位置的发送资源为可用资源,1表示该位置的发送资源为不可用资源,当然,也可以是1表示该位置的发送资源为可用资源,0表示该位置的发送资源为不可用资源,本发明实施例对此不做限制。下面将以0表示该位置的发送资源为可用资源,1表示该位置的发送资源为不可用资源为例进行介绍。
若是资源状态信息用于表征子帧级别的发送资源的占用状态,1个bit位可以表示一个子帧的状态,则1000个子帧需要1000bit。具体的,若在某一子帧的bit位上为1,则表示该子帧包括的部分子信道或者全部子信道为不可用资源;若在某一子帧的bit位上为0,则表示该子帧包括的全部子信道都为可用资源。
若是资源状态信息用于表征子信道集合级别的发送资源的占用状态,1个bit位可以表示一个子信道集合的状态,因为一个子帧包括的10个子信道可以组合成7种子信道集合,则1000个子帧的子信道集合需要7000bit。具体的,若在某一子信道集合的bit位上为1,则表示该子信道集合包括的部分子信道或者全部子信道为不可用资源;若在某一子信道集合的bit位上为0,则表示该子信道集合包括的全部子信道都为可用资源。
若是资源状态信息用于表征子信道级别的发送资源的占用状态,1个bit位可以表示一个子信道的状态,则1000个子帧包括10000个子信道,则总共需要10000bit。具体的,若在某一子信道的bit位上为1,则表示该子信道为不可用资源;若在某一子信道的bit位上为0,则表示该子信道为可用资源。
具体的,若用户设备发送的资源状态信息为用于指示发送资源在时频域中的位置的资源位置信息,为了便于区分,用户设备发送的资源位置信息对应的发送资源可以是可用资源,也可以是不可用资源,具体的则可以实际情况进行设置。为了便于定位发送资源的位置,需要设置一个基准位置,那么这里的资源位置信息则是指发送资源相对于基准资源的相对位置。例如将发送位置信息的时刻对应的子帧设置为为基准位置,则用户设备发送的资源状 态信息则是用于指示发送资源与该基准位置的距离。在基站接收到资源位置信息后,则可以进过一定的换算可以知道发送资源的实际位置。其中,这个基准位置可以是预先设置好的,并且基站和用户设备默认的基准位置必须相同,否则基站换算得到的发送资源的位置则是不准确的;或者,用户设备在发送资源状态信息时,将基准位置同时发送给基站;基准位置也可以是基站将基准位置发送给用户设备的。
若用户设备发送的资源状态信息为用于指示发送资源在时频域中的位置的资源位置信息,则用户设备发送的资源位置信息的计算如下。
若用户设备发送的资源位置信息是子帧级别的,由于总共有1000个子帧,则需要10个bit位则可以表示出1000个子帧的可能的情况。因为将10个bit位上的状态进行排列组合则有2的10次方种排列方式,一种排列方式代表一个子帧的位置,则完全可以表示出1000个子帧的位置信息。因此,表达一个子帧的位置需要10bit。
若用户设备发送的资源位置信息是子信道集合级别的,则首先需要10个bit位来表示这个子信道集合处于的子帧的位置。其次,由于一个子帧包括10个子信道,并且可能出现7种子信道集合,则需要3个bit位则可以表示出7个子帧的可能的情况。因为将3个bit位上的状态进行排列组合则有2的3次方种排列方式,一种排列方式代表一个子信道集合的位置,则完全可以表示出1个子帧包括的7种子信道集合的位置信息。因此,表达一个子信道集合的位置需要13bit。
若是用户设备需要发送20个资源位置信息给基站,则若用户发送子帧级别的,则需要20x10=200bit;则若用户发送子信道集合级别的,则需要20x13=260bit。
本发明实施例中,发送资源还可以按照周期或者持续时间的不同来进行分类,其中,若按周期分类,周期可以是可被允许的全部或部分的周期。那么用户设备发送的资源状态信息还可以包括发送资源的分类信息,并且还可以包括各种分类下的发送资源的数量。例如将发送资源按照周期分类时,则 可以将发送的每种周期的发送资源的资源状态信息的数量也发送给基站。具体的,发送资源的周期例如可以是20ms,50ms,100ms,当然,发送资源的周期还可以是其他可能的周期,本发明对此不做限制。其中,通过周期为100ms的发送资源发送消息的用户设备也可以通过周期为20ms或者50ms的发送资源发送消息,那么在用户设备发送给基站的周期为100ms的发送资源的资源状态信息的数量也可以包括周期为20ms或者50ms的发送资源的资源状态信息的数量。当然,为避免重复,当在用户设备发送的资源状态信息中已经包括了周期为20ms或者50ms的发送资源的资源状态信息的数量时,则在发送周期为100ms的发送资源的资源状态信息的数量时,则可以将其去除。
本发明实施例中,用户设备将资源状态信息发送给基站后,基站可以接收该资源状态信息。基站接收到该用户资源信息后,就可以根据该资源状态信息和基站已经为第一模式用户设备分配的发送资源信息确定在共享发送资源池中还是否包括可用资源。具体的,若用户设备发送的资源状态信息是表明共享发送资源池中的其中一部分发送资源为不可用资源,则基站可以根据该资源状态信息确定与该资源状态信息相反的其他发送资源位可用资源,还可以进一步的,从这些可用资源中将基站已经为第一模式用户设备分配过的发送资源去除,若最终还有剩余的发送资源,则该剩余的发送资源则为实际真正空闲的可用资源,也就是说可以确定在共享发送资源池中还包括可用资源。
本发明实施例中,基站确定在共享发送资源池中还包括可用资源之后,则可以根据这些可用资源来为第一模式用户设备分配发送资源。
本发明实施例中,在基站确定第一模式用户设备及第二模式用户设备共享的共享发送资源池中是否包括可用资源之前,基站还可以接收外部设备发送的辅助信息,该辅助信息至少包括外部设备的地理位置信息。其中,外部设备可以是在发送资源状态信息的同时将辅助信息发送给基站,也可以是在发送资源状态信息之前或者之后将辅助信息发送给基站,本发明实施例对此不作限制。那么在基站为第一模式用户设备分配发送资源时,则还可以考虑 到第一模式用户设备的地理位置信息来分其分配更合适的发送资源。
本发明实施例中,在基站给第一模式用户设备分配发送资源之后,还可以接收用户设备发送的冲突信息。具体的,冲突信息可以是发生冲突的第一用户设备中的一个或者多个发送给基站的,也可以是其他设备发送给基站的。其他设备则是指知道了有第一用户设备占用的发送资源发生冲突的用户设备。其中,冲突信息中可以包括用于指示发生冲突的发送资源的信息和/或包括用于指示发生冲突的第一用户设备的信息。冲突信息中也可以包括辅助信息,例如辅助信息为发送冲突信息的其他用户设备的地理位置信息和/或发生冲突的第一用户设备的地理位置信息。冲突信息中还可以包括优先级信息,例如包括道路安全消息包括的数据的优先级信息或者用户设备的优先级信息。
此外,如果是发生冲突的用户设备发现了自己的发送资源发生了冲突,并且该用户设备是第二模式用户设备,则该用户设备也可以重新在共享发送资源池中选择其他可用资源。如果是其它设备发现了发送资源发生了冲突,所述其它设备也可以在自己发送的道路安全消息包括的有关道路安全的消息数据和/或SA中,包括用于指示发生冲突的发送资源的信息和/或发生冲突的用户设备的信息。
基站根据接收的冲突信息,则可以确定是否有第一用户设备的发送资源发生冲突。
若基站确定在所有用户设备中存在发送资源冲突的第一用户设备,但是基站不能确定是哪些设备的发送资源发生了冲突,则基站可以给所有用户设备发送冲突消息,以使的所有用户设备都知道是哪些发送资源发生了冲突,则用户设备可以确定是否是自己的发送资源发生了冲突,若是的话,则可以进行相应处理。其中,若是第一模式用户设备确定是自己的发送资源发生了冲突,则第一模式用户设备可以通知基站为其重新分配发送资源;若是第二模式用户设备确定是自己的发送资源发生了冲突,则第二模式用户设备可以重新选择发送资源。
本发明实施例中,基站也可以根据接收的冲突信息确定是哪些发送资源 和/或哪些设备的发送资源发生了冲突,另外,基站还可以结合用户设备发送的资源状态信息来进行确定。当基站确定有第一用户设备的发送资源发生冲突后,若是基站确定发生冲突的第一用户设备包括第一模式用户设备时,则基站可以基于共享发送资源池中其他的可用资源,给所述第一用户设备中的其中至少一个第一模式用户设备重新分配发送资源。当然,在基站确定的第一用户设备包括的第一模式用户设备可以是第一用户设备只包括第一模式用户设备,也可以是基站确定的第一用户设备中包括第一模式用户设备,但是与该第一模式用户设备的发送资源冲突的另外一个或者多个用户设备基站还不能确定,那么这里的另外一个或者多个用户设备则有可能是第一模式用户设备,也有可能是第二模式用户设备。例如,若是另外一个或者多个用户设备为第一模式用户设备,也就是说,发送资源发生冲突的用户设备皆为第一模式用户设备,则基站可以给其中一个或者多个第一模式用户设备重新分配资源。
若基站确定有第一用户设备的发送资源发生冲突后,若是基站确定发生冲突的第一用户设备包括第二模式用户设备时,则基站会给该第二模式用户设备发送第三指示消息,第三指示消息则是用于指示第一用户设备中的其中至少一个第二模式用户设备更换发送资源。当然,在基站确定的第一用户设备包括的第二模式用户设备可以是第一用户设备只包括第二模式用户设备,也可以是基站确定的第一用户设备中包括第二模式用户设备,但是与该第二模式用户设备的发送资源冲突的另外一个或者多个用户设备基站还不能确定,那么这里的另外一个或者多个用户设备则有可能是第一模式用户设备,也有可能是第二模式用户设备。例如,若是另外一个或者多个用户设备为第二模式用户设备,也就是说,发送资源发生冲突的用户设备皆为第二模式用户设备,则基站可以给其中一个或者多个第二模式用户设备发送第三指示消息。
若所述基站确定有第一用户设备的发送资源发生冲突后,若是基站确定发生冲突的第一用户设备包括第一模式用户设备和第二模式用户设备时,则基站会基于共享发送资源池中其他的可用资源,给第一用户设备包括的第一 模式用户设备重新分配发送资源;或者,基站会给第一用户设备包括的第二模式用户设备发送第三指示消息,指示第二模式用户设备更换发送资源。
还可以向所述第二模式用户设备发送用于表征已经分配给所述第一模式用户设备的发送资源的第二指示消息,使得第二模式用户设备在共享发送资源池中选择发送资源时,能够避开这些已经分配给第一模式用户设备的发送资源,也就能够避免第二模式用户设备和第一模式用户设备占用的发送资源发生冲突。
由于可能因为用户设备发送的资源状态信息是不完全的,也就是说不能包括共享发送资源池中所有发送资源的状态,则基站基于此资源状态信息确定的可用资源则有可能与第二模式用户设备正在占用的发送资源冲突。那么,在基站给第一模式用户设备分配发送资源之后,基站还可以给第二模式用户设备发送第四指示消息,该第四指示消息用于指示第二模式用户设备向基站发送第二模式用户设备选择的发送资源的信息。这里的第二模式用户设备可以是部分的第二模式用户设备,也可以是全部的第二模式用户设备。
在基站接收到第二模式用户设备选择的发送资源的信息之后,基站则可以根据第二模式用户设备选择的发送资源与基站为第一模式用户设备分配的发送资源,确定第二模式用户设备选择的发送资源与基站为第一模式用户设备分配的发送资源是否冲突。
若是基站确定第二模式用户设备选择的发送资源与基站为第一模式用户设备分配的发送资源发生冲突,则基站可以重新确定共享发送资源池中其他的可用资源,再给第一模式用户设备重新分配发送资源;或者,基站也可以给与基站为第一模式用户设备分配的发送资源发生冲突的第二模式用户设备发送第三指示消息,该第三指示消息则是用于指示该第二模式用户设备更换其他的发送资源。
本发明实施例中,为了保证第一模式用户设备的传输性能,基站还可以为第一模式用户设备另外分配一个相对较小的专用发送资源池。在基站确定在共享发送资源池中没有包括可用资源之后,则可以利用专用发送资源池中 的发送资源来为第一模式用户设备分配资源。
综上,在基站给第一模式用户设备分配发送资源之前,基站首先会确定共享发送资源池中的哪些资源为可用资源,然后根据这些可用资源来为第一模式用户设备分配发送资源,这样也就可以避免将第二模式用户设备已经占用的发送资源分配给第一模式用户设备,进而也就避免了第一模式用户设备和第二模式用户设备的发送资源发生冲突。
