Description
本发明涉及通信技术领域,特别涉及一种资源分配方法及装置。
IoV(Internet of Vehicles,车联网)是基于互联网与物联网技术的结合,同时融入大量软件技术和信息服务内容的新型管理服务网络。在车联网中,以车辆为节点和信息源,利用先进的传感技术、网络技术和无线通信技术,通过车辆或手机处理和共享大量信息,实现“人-车-路-环境-社会”的互联互通,达到智能化识别、定位、跟踪、监管和推送服务,从而实现更智能、更安全、更环保、更舒适的驾乘体验与服务。
由于车辆内配置有通信单元,因此可以把车辆看做是一个UE(User Equipment,用户设备)。现有技术中,在UE需要与其他UE或其他设备进行通信之前,UE可以向基站发送传输资源请求,当基站接收到UE发送的传输资源请求时,由于基站无法根据该传输资源请求确定终端的位置,因此,为了避免在未知车辆位置的情况下,向车辆分配相同传输资源而可能带来的传输冲突,基站会为不同的UE分配不同的传输资源,从而使得UE能够在分配的传输资源上与其他UE进行正常的通信,进而实现人-车-路-环境-社会”的互联互通。
在实现本发明的过程中,发明人发现现有技术至少存在以下问题:
当基站覆盖的小区内UE数量较多,并且车辆对传输资源的需求很大时,由于基站覆盖区域内的传输资源有限且不能复用,会导致基站可能没有剩余资源可分配,以至于一些车辆不能进行通信,传输资源的复用率较低,且车辆的通信效率较低。

上述所有可选技术方案,可以采用任意结合形成本发明的可选实施例,在此不再一一赘述。
结合图1所示的实施场景示意图及上述所示实施例的内容,图7是本发明实施例提供的一种资源分配方法的流程图,参见图7,该方法包括:
701、基站向覆盖范围内的UE发送侦听设置信息,所述侦听设置信息用于通知UE进行侦听的持续时长。
可选地,由于UE的移动性以及UE与基站之间进行通信的信号可能存在
的不稳定性,都可能会导致UE未成功接收到基站发送的侦听设置信息,因此,在本发明实施例的一种可选实现方式中,为了保障基站覆盖范围内的所有UE都能够成功接收到基站发送的侦听设置请求,基站可以设置一个发送周期,周期性的向覆盖范围内的UE发送侦听设置信息,从而使得基站覆盖范围内的所有UE都能接收到该侦听设置信息。
该侦听设置信息可以通过多种形式发送,例如,可以通过RRC(Radio Resource Control,无线资源控制协议)信令、SIB(System Information Block,系统信息块)消息或控制信令发送,具体地,该发送过程可以包括:基站向站覆盖范围内的UE发送RRC信令,所述RRC信令携带所述侦听设置信息;或,基站向覆盖范围内的UE发送SIB消息,所述SIB消息携带所述侦听设置信息;或,基站向覆盖范围内的UE发送控制信令,所述控制信令携带所述侦听设置信息。
702、第一UE接收基站发送的侦听设置信息。
在本发明实施例中,是以进行侦听的持续时长由基站设置为例进行说明的,在实际场景中,该进行侦听的持续时长不仅可以由基站设置,还可以是用户设备上预定义的时长,该预定义时长可以是第一UE在出厂前,厂商为其内置的一个固定值。当然,该持续时长还可以由用户进行设置,UE可以提供自行设置持续时长的功能,用户在UE上自行输入预设时长,如,用户可以输入10ms,20ms等等,本发明实施例对此不作限定,当UE检测到用户输入时长时,将用户输入的时长设置为对传输资源进行侦听的持续时长。
本发明实施例可以根据UE对通信质量的要求,设置不同的侦听持续时长,如,当UE的数据传输量较大、需要很多空闲传输资源时,可以将持续时长设置为一个较大的值,从而使得UE在较长的时间内对传输资源进行侦听,进而侦听到更多空闲的传输资源。当UE对侦听的空闲传输资源数量没有特殊要求时或者UE对传输的时效性要求较高时,也可以将该持续时长设置为一个较小的值,从而能够及时结束侦听,从而尽快获取到传输资源。
703、第一UE根据所述侦听设置信息,确定对基站覆盖范围内传输资源进行侦听的持续时长。
当第一UE接收到基站发送的侦听设置请求时,将侦听设置请求中携带的持续时长作为第一UE对传输资源进行侦听的持续时长。
704、第一UE对基站覆盖范围内传输资源进行侦听。
在本发明实施例中,该侦听可以是指对传输资源进行能量检测,如果在传
输资源上存在UE进行通信的信号,并且该UE与第一UE距离很近时,该传输资源的能量检测值相对较高,当在传输资源上不存在UE进行通信的信号时,或者在传输资源上存在UE进行通信的信号,并且该UE与第一UE距离很远时,该传输资源的能量检测值相对较小,因此本发明实施例中采用对传输资源进行能量检测,并根据能量检测值,判断传输资源是否空闲。具体地,第一UE对基站覆盖范围内的传输资源进行侦听包括:第一UE对传输资源进行能量检测,得到能量检测值;当所述能量检测值小于第一能量阈值时,则认为该传输资源为空闲,第一UE获取该空闲的传输资源的传输资源索引,当第一UE对传输资源进行侦听的时长到达预设时长时,停止对传输资源进行侦听。
其中,该第一能量阈值可以是由基站设置,在这种情况下,在该步骤704之前,还可以包括:基站向覆盖范围内的UE发送能量阈值信息,该能量阈值信息用于通知UE进行侦听时的第一能量阈值,当UE接收到该能量阈值信息时,根据该第一能量阈值对用户设备自身进行设置。当然,在实际场景中,该第一能量阈值不仅可以由基站设置,还可以是用户设备上预定义的第一能量阈值,本发明实施例不对第一能量阈值的来源做具体限定。
需要说明的是,该能量阈值信息可以通过多种形式发送,例如,可以通过RRC信令、SIB消息或控制信令发送,具体地,该发送过程可以包括:向基站覆盖范围内的UE发送RRC信令,所述RRC信令携带所述能量阈值信息;或,向基站覆盖范围内的UE发送SIB消息,所述SIB消息携带所述能量阈值信息;或,向基站覆盖范围内的UE发送控制信令,所述控制信令携带所述能量阈值信息。
由于基站覆盖范围内的传输资源可能有多个,因此,在实际进行侦听的过程中,可以采取轮询的方式对不同的传输资源进行侦听或采取并行的方式对不同的传输资源进行侦听。
705、第一UE通过侦听获取空闲传输资源索引。
该空闲传输资源索引用于标识第一UE通过侦听所得到的空闲传输资源。本发明实施例是以侦听到空闲传输资源为例进行说明的,而在实际场景中,第一UE通过侦听,可能侦听不到任何空闲传输资源,因此,也就无法得到空闲传输资源索引,这种情况下,在向基站发送资源分配请求时,可以不携带任何传输资源索引,以使得基站获知当前第一UE的需求。
进一步地,第一UE所侦听到的空闲传输资源可能有多个,则为了避免资
源浪费以及减少信令负担,基站还可以向覆盖范围内的UE发送数目设置信息,所述数目设置信息用于通知UE在发送资源分配请求时携带传输资源索引的个数,使得UE在接收到该数目设置信息时,根据该数目设置信息所携带的个数,设置发送资源分配请求时携带传输资源索引的个数。
具体地,当第一UE侦听到的空闲的传输资源个数大于数目设置信息中携带的传输资源索引个数时,则在资源分配请求中携带数目设置信息中指定的数目,当第一UE侦听到的空闲的传输资源个数小于数目设置信息中携带的传输资源索引的个数时,则在资源分配请求中携带UE侦听到的所有空闲传输资源索引。如,当第一UE侦听到的空闲的传输资源个数为8,数目设置信息中携带传输资源索引的个数为5时,则在资源分配请求中携带5个传输资源索引;当第一UE侦听到的空闲的传输资源个数为8,数目设置信息求中携带传输资源索引的个数为10时,则在资源分配请求中携带8个传输资源索引。
另外,当第一UE侦听到空闲传输资源时,在本发明另一实施例中,还可以根据各个空闲传输资源的能量检测值从小到大的顺序,对空闲传输资源索引进行排序,在资源分配请求中携带排序后的空闲传输资源索引。当然,在第一UE侦听到的空闲的传输资源个数大于数目设置信息中携带的传输资源索引个数时,可以按照能量检测值的排序顺序,从中获取与数目设置信息中携带的传输资源索引个数的空闲传输资源索引。由于UE之间的距离等因素,UE所侦听到的空闲传输资源不一定是实际空闲的,而能量检测值越小,该传输资源是空闲资源的可能性越大,如此,将能量检测值较小的空闲传输资源上报给基站,使得基站在其中为第一UE进行资源分配,可以大大提高分配成功率。
706、当侦听时长达到预设时长时,第一UE向基站发送资源分配请求,该资源分配请求携带第一UE侦听得到的空闲传输资源索引。
在本发明实施例中,以资源分配请求携带第一UE侦听得到的空闲传输资源索引为例进行说明。
707、基站接收第一UE发送的资源分配请求。
708、如果所述资源分配请求携带所述第一UE侦听得到的传输资源索引,基站根据所述传输资源索引,为所述第一UE分配传输资源。
该传输资源索引所对应的传输资源可以是已分配的传输资源或空闲传输资源,对于已分配的情况,由于被分配的UE与第一UE之间距离较大,其通信也不会互相影响,因此,可以直接将该传输资源索引对应的传输资源分配给
第一UE。
709、基站向所述第一UE发送所分配的传输资源。
710、第一UE接收所述基站分配的传输资源,基于该分配的传输资源进行通信。
第一UE可以基于分配的传输资源向其他UE发送车车通信的信号或向基站发送信号,本发明实施例对此过程不作具体限定。
本发明实施例提供的方法,通过UE对基站所提供的传输资源进行侦听,从而能够获知处于空闲状态的传输资源,并主动向基站请求空闲传输资源,使得基站基于UE的上报进行资源分配,从而实现了传输资源分配的合理化,提高了传输资源的复用率以及车联网中车辆间通信的成功率。
上述图7所示的实施例是以第一UE侦听到空闲传输资源为例进行说明的,而在实际场景中,第一UE也可能侦听不到任何空闲传输资源,为了实现车车通信并提高资源复用率,本发明实施例还提供了另一种可能实现方式,参见图8,该实现方式具体包括:
801、基站向覆盖范围内的UE发送侦听设置信息,所述侦听设置信息用于通知UE进行侦听的持续时长。
802、第一UE接收基站发送的侦听设置信息。
803、第一UE根据所述侦听设置信息,确定对基站覆盖范围内传输资源进行侦听的持续时长。
804、第一UE对基站覆盖范围内传输资源进行侦听。
上述步骤801-804与步骤701-704同理,在此不作赘述。
805、第一UE通过侦听未获取到任何空闲传输资源索引。
806、当侦听时长达到预设时长时,第一UE向基站发送资源分配请求,该资源分配请求不携带传输资源索引。
807、基站接收第一UE发送的资源分配请求。
808、如果所述资源分配请求未携带任何传输资源索引,根据基站传输资源的分配情况,为第一UE分配传输资源。
具体地,该过程包括步骤808A-808E:
808A、判断基站是否有未被分配的传输资源,如果是,执行步骤808B,如果否,执行步骤808C。
基站会根据自身对资源的分配,保存有传输资源的分配情况,如,哪个传输资源已经被分配以及被分配给了哪个UE,因此,通过查询基站传输资源的分配情况,可以获知基站当前是否还有可分配的传输资源。
808B、如果基站有未被分配的传输资源,将未被分配的传输资源分配给所述第一UE。
本发明实施例中,基站可以根据资源分配请求中携带的传输资源索引,随机将任一个未被分配的传输资源分配给第一UE。本发明实施例不对基站为第一UE分配传输资源的方式做限定。
808C、如果基站所有传输资源均已经被分配,获取所述第一UE的位置信息。
其中,步骤808C中“获取所述第一UE的位置信息”可以通过以下三种可能实现方式中任一种方式实现:
第一种可能实现方式、接收所述第一UE的位置信息。
具体地,该“接收第一UE的位置信息”可以有三种可能实现方式:(1)接收所述第一UE的GPS位置信息。对于配置有GPS定位系统的UE,可以通过自身所配置的GPS定位系统获取GPS位置信息,并将GPS位置信息发送给基站,使得基站接收到UE的GPS位置信息。(2)接收所述第一UE的估计位置信息,所述估计位置信息为第一UE根据基站发射的定位参考信号进行估计得到的位置信息。对于一些没有定位系统的UE来说,可以根据自身接收到的定位参考信号对自身的位置信息进行估计,从而得到估计位置信息,并将估计位置信息发送给基站,使得基站接收到UE的估计位置信息。(3)接收所述第一UE当前的区域索引信息。在实际场景中,还可以采取隐式上报位置的方式,例如,基站将自身的覆盖范围按照地理位置划分成了多个区域,每个区域对应于不同的区域索引信息,而区域内的终端能够根据自身当前状态,如自身的位置信息(GPS位置信息或估计位置信息等),判断自己现在所处的区域,从而将对应区域的区域索引信息发送给基站,使得基站接收到该区域索引信息后,根据区域索引,确定UE当前的位置信息。
第二种可能实现方式、根据所述第一UE的发射信号,确定所述第一UE的位置信息。
在本发明实施例中,第一UE的发射信号可以为SRS(Sounding Reference Signal,侦听参考信号)、RACH(Random Access Channel,随机接入信道)、
PUCCH(Physical Uplink Control Channel,物理上行控制信道)、PUSCH(Physical Uplink Share Channel,物理上行共享信道)、用于承载SR(Scheduling Request,调度请求)的物理上行链路控制信道PUCCH信号、用于承载BSR(Buffer Status Report,缓存状态报告)的物理上行共享信道PUSCH信号或所述第一UE与其他UE之间的通信信号。其中,如果第一UE当前与基站之间存在业务传输,则可以利用PUCCH信号、PUSCH信号或SRS信号等确定第一UE的位置信息。而如果此时第一UE是通过SR请求用于进行车车通信的资源,则可以利用用于承载SR的物理上行链路控制信道PUCCH信号、用于承载BSR的物理上行共享信道PUSCH信号等确定第一UE的位置信息。而如果基站能够接收到车车通信的通信信号,可以利用第一UE与其他UE之间的通信信号确定第一UE的位置信息。
具体地,该第二种可能实现方式包括:根据所述第一UE的发射信号,确定所述第一UE与基站之间的相对方位;根据所述第一UE的发射信号的能量检测值,确定所述第一UE与基站之间的距离。具体地,基站可以根据第一UE的发射信号,确定第一UE与基站之间的相对方位。如,根据第一UE的发射信号,确定第一UE在基站的东侧。基站根据第一UE的发射信号的能量检测值,确定第一UE距离基站的距离。如,基站根据第一UE的发射信号的能量检测值。确定第一UE距离基站的为500米。根据基站确定出的第一UE与基站之间的相对方位和与基站之间的距离,确定了第一UE的位置信息。
在车车通信过程中,UE会向其他UE发送自身的状态信息,状态信息可以包括车辆位置、行驶方向、行驶速度等信息,而由于车车通信是以广播形式进行传输的,因此,基站也可能会成功接收到车车通信的通信信号,对通信信号进行解析,从而确定UE的位置信息。
第三种可能实现方式、将上一次获取到的所述第一UE的位置信息,作为当前所述第一UE的位置信息。
当然,为了节省计算资源,还可以获取上一次已经获取到的第一UE的位置信息,作为第一UE当前的位置信息。
808D、根据所述第一UE的位置信息和当前已分配传输资源的UE的位置信息,确定符合预设条件的第二UE,所述预设条件为所述第二UE与所述第一UE之间的距离大于第一预设距离。
808E、将已分配给所述第二UE的传输资源分配给所述第一UE。
其他UE的位置信息获取方法可以与上述获取第一UE的位置信息方法同理,在此不作赘述。
为了在保证通信质量的同时提高资源复用率,在进行资源分配时,可以根据获取到的第一UE的位置信息,在当前已分配传输资源的UE中查找第二UE,当UE之间的距离大于第一预设距离,则对其通信质量的影响最小,因此,可以将为第二UE分配的传输资源分配给所述第一UE。该第一预设距离可以由基站预设,例如,车车通信的传输距离为300米,基站可以根据UE之间的位置信息,为两个距离大于600米的UE分配相同的传输资源,该距离至少是车车传输距离的两倍,此时,该两个车辆之间不会存在传输冲突及隐藏节点问题。
809、基站向所述第一UE发送所分配的传输资源。
810、第一UE接收所述基站分配的传输资源,基于该分配的传输资源进行通信。
该步骤809-810与步骤709-710同理,在此不作赘述。
本发明实施例提供的方法,通过UE对基站所提供的传输资源进行侦听,从而能够获知处于空闲状态的传输资源,并主动向基站请求空闲传输资源,使得基站基于UE的上报进行资源分配,从而实现了传输资源分配的合理化,提高了传输资源的复用率以及车联网中车辆间通信的成功率。进一步地,即使所侦听到的资源并不是实际空闲的传输资源,仍可以根据UE之间的距离为当前请求资源的UE进行资源分配,在不影响其他UE的通信的情况下,提高了传输资源的复用率。
上述图7和图8所示的实施例是以第一UE进行侦听为例进行说明的,而在实际场景中,也可以无需启动侦听过程,而是直接基于第一UE的位置信息为其进行资源分配,相应地,本发明实施例还提供了另一种可能实现方式,参见图9,该实现方式具体包括:
901、第一UE向基站发送资源分配请求,该资源分配请求不携带传输资源索引。
本发明实施例中,以UE不进行侦听过程为例进行说明。
902、基站接收第一UE发送的资源分配请求。
903、基站判断是否有未被分配的传输资源,如果否,执行步骤904。
在本发明实施例的另一种实现方式中,如果基站有未被分配的传输资源,
将未被分配的传输资源分配给所述第一UE。
904、基站获取所述第一UE的位置信息。
在资源分配请求未携带任何传输资源索引时,说明该第一UE没有进行资源侦听,或者进行了资源侦听但是未侦听到任何空闲传输资源,则此时,为了保证第一UE的通信成功率并提高资源复用率,可以根据第一UE的位置信息为其进行资源分配。
该获取第一UE的位置信息的过程与上述步骤808C同理,在此不做赘述。
905、根据所述第一UE的位置信息和当前已分配传输资源的UE的位置信息,确定符合预设条件的第二UE,所述预设条件为所述第二UE与所述第一UE之间的距离大于第一预设距离;将已分配给所述第二UE的传输资源分配给所述第一UE。
基站为第一UE分配传输资源,此时分为两种情况。第一种情况,基站有空闲的传输资源,则基站将可用的空闲资源分配给第一UE;第二种情况,基站所有的传输资源都被占用,基站根据所述第一UE的位置信息和当前已分配传输资源的UE的位置信息,将已分配给第二UE的传输资源分配给所述第一UE,所述第二UE与所述第一UE之间的距离大于第一预设距离。
该步骤905与上述步骤808D同理,在此不作赘述。
906、基站向所述第一UE发送所分配的传输资源。
907、第一UE接收所述基站分配的传输资源,基于该分配的传输资源进行通信。
该步骤906-907与步骤709-710同理,在此不作赘述。
本发明实施例提供的方法,通过根据UE的位置信息,确定UE之间的距离,从而能够为距离大于第一预设距离的UE分配相同的传输资源,从而实现资源服用,并在不影响UE之间通信的情况下,提高了传输资源的复用率。
进一步地,上述图8~图10所示实施例中,均是针对如何分配传输资源为例进行说明,而在进行了传输资源的复用之后,还需要提高通信成功率,也即是避免资源冲突的发生,为此,本发明实施例在上述实施例的基础上,也即是已经为第一UE和第二UE分配了相同的传输资源的基础上,还提供了一种冲突检测方法,参见图10,该冲突检测方法包括:
1001、基站向第一UE和第二UE分别发送资源复用消息,所述资源复用消息用于通知所述第一UE和所述第二UE分配了相同的传输资源。
基站可以通过发送该资源复用消息触发第一UE和第二UE周期性的向基站发送自身的位置信息,以使基站根据第一UE和第二UE的位置信息判断是否存在资源冲突。
1002、当第一UE和第二UE接收到基站发送的资源复用消息时,周期性向基站发送用户设备自身的位置信息。
该发送过程可以与上述实施例中UE发送UE自身位置信息同理,在此不作赘述。
1003、基站实时根据第一UE和所述第二UE的位置信息,判断所述第一UE和所述第二UE之间的距离是否小于第二预设距离,如果是,则执行步骤1004,如果否,继续执行获取位置信息和判断的步骤。该第二预设距离可以由基站设定。
1004、当确认所述第一UE和所述第二UE之间的距离小于第二预设距离时,基站确定所述第一UE与所述第二UE之间存在资源冲突。
该第二预设距离小于或等于第一预设距离,当UE之间相距小于第二预设距离时,可以认为UE的通信质量会受到影响,此时可以确定所述第一UE与所述第二UE之间存在资源冲突。
上述步骤1001和1002以基站根据第一UE和第二UE发送的位置信息,确定是否存在资源冲突为例进行说明的,在实际场景中,本发明还提供的其他两种确定是否存在资源冲突的可能实现方式:
第一种可能实现方式,当接收到所述第一UE发送的资源冲突消息时,确定所述第一UE和所述第二UE之间存在资源冲突,所述资源冲突消息由所述第一UE在静默时对所述传输资源进行检测得到。
需要说明的是,UE可以根据预先设置的静默方式在通信过程中进行静默。静默是指该UE在某个传输时隙中不进行信号或数据的发送,仅进行信号或数据的接收,此时,在静默状态下,UE可以通过对传输资源的侦听,确认该传输资源是否被占用。该预设设置的静默方式可以由基站设置、用户设备上预定义或者由用户设置的。例如,基站可以向第一UE和所述第二UE分别发送静默设置信息,所述静默设置信息用于通知UE在指定传输时隙中静默。如,该静默设置信息可以用于通知UE在5次传输机会中静默1次,并在静默资源内,对所分配的传输资源进行能量检测。
当第一UE或第二UE确定静默方式后,在指定传输时隙中检测到所分配
的传输资源的能量检测值大于第二能量阈值时,确定该传输资源上存在资源冲突,并生成资源冲突消息。当第一UE或第二UE生成资源冲突消息时,向基站发送该资源冲突消息,以使基站根据该资源冲突消息,确定第一UE和第二UE之间存在资源冲突。其中,该第二能量阈值可以是由基站设置,在这种情况下,在该步骤1004之前,还可以包括:基站向覆盖范围内的UE发送能量阈值信息,该能量阈值信息用于通知UE进行侦听时的第二能量阈值,当UE接收到该能量阈值信息时,根据该第二能量阈值对UE自身进行设置。当然,在实际场景中,该第二能量阈值不仅可以由基站设置,还可以是用户设备上预定义的第二能量阈值,本发明实施例不对第二能量阈值的来源做具体限定。
为了提高静默检测的精准度,第一UE和第二UE可以采用不同的静默方式,以使第一UE和第二UE在不同的传输时隙中静默,避免了第一UE(或第二UE)在指定传输时隙中静默时,第二UE(或第一UE)也在该次传输时隙中静默,从而导致第一UE因检测所占用的传输资源的能量检测值小于第二能量阈值而误判。
其中,基站可以根据UE的ID(Identity,身份标识)或者UE所接入的小区标识,向不同的UE发送不同的静默设置信息,该静默设置信息可以是随机的,如,向第一UE发送的静默设置信息用于通知第一UE在每10次传输时隙中的第5次静默,向第二UE发送的静默设置信息用于通知第二UE在每10次传输时隙中的第8次静默,当然静默设置信息也可以是以遵从某一原则的,如,静默的传输时隙依次按序递增,如,向第一UE发送的静默设置信息用于通知第一UE在每10次传输时隙中的第1次静默,向第二UE发送的静默设置信息用于通知第二UE在每10次传输时隙中的第2次静默。向不同的UE发送不同的静默设置信息,从而使第一UE和第二UE采用不同的静默方式。当然,第一UE也可以在第一UE上自行设置与第二UE不同的静默机制,本发明实施例不对第一UE和第二UE确定不同的静默机制的方式做限定。
当然,上述过程中的资源冲突消息是由第一UE发送的,在实际场景中,第二UE在静默时对传输资源进行检测,也可能会检测到传输资源已被其他UE占用,此时,第二UE也可以向基站发送资源冲突消息,也即是,当基站接收到所述第二UE发送的资源冲突消息时,确定所述第一UE和所述第二UE之间存在资源冲突,所述资源冲突消息由所述第二UE在静默时对所述传输资源进行检测得到。
第二种方式:当接收到第三UE发送的资源冲突消息时,确定所述第一UE和所述第二UE之间存在资源冲突,所述第三UE为在基站覆盖范围内除所述第一UE和所述第二UE之外的UE,所述资源冲突消息由所述第三UE对所述传输资源进行检测得到。
为了及时获知资源冲突,基站可以向覆盖范围内的UE发送广播消息,所述广播消息携带所述传输资源索引,以使基站覆盖范围内的UE对所述传输资源进行检测。
具体的,在基站为第一UE和第二UE分配相同的传输资源后,基站会发送广播消息,该广播消息携带为第一UE与第二UE分配的传输资源索引,以使基站覆盖范围内的UE对传输资源进行检测。当第三UE接收到基站发送的广播消息时,根据广播消息中携带的传输资源索引,对所述传输资源进行检测;如果所述检测模块在该传输资源上成功检测到信号,但是随着第三UE自身的移动,该传输资源上的信号能量的变化幅度小于预设阈值,并且在传输资源上不能再次成功检测到信号,且在预设时长内仍无法成功检测到信号,则确定第一UE和第二UE之间存在资源冲突,第三UE向基站上报资源冲突指示。
1005、确定所述第一UE与所述第二UE之间存在资源冲突时,基站重新为所述第一UE或所述第二UE分配传输资源。
具体如何重新为第一UE或第二UE分配传输资源可以基于基站的分配方式确定,如,可以根据第一UE和第二UE的业务优先级等确定重新为哪个UE进行分配。如果第一UE的业务优先级高,则可以重新为第二UE分配传输资源。当然,还可以随机对其中一个UE进行重新分配,或者,对两个UE均进行重新分配,只要所分配的传输资源不同即可,本发明实施例对此不作限定。当然,对其中任一个UE进行重新分配时,可以依据本发明实施例所提供的资源分配方式进行。
1006、基站向第一UE或第二UE发送所分配的传输资源。
本发明实施例提供的方法,通过基站向第一UE和第二UE发送资源复用消息,以使第一UE和第二UE周期性向基站发送UE自身的位置信息,当基站接收到第一UE和第二UE发送的位置信息时,判断第一UE和第二UE之间的距离是否小于第二预设距离,当基站判断第一UE和第二UE之间的距离小于第二预设距离时,确定第一UE与第二UE之间存在资源冲突,并重新为第一UE或第二UE分配传输资源,从而实现传输资源分配的合理化,提高传
输资源的复用率以及车联网中车辆间通信的成功率。
