Description

资源分配方法、装置及系统 技术领域
本申请涉及互联网技术,尤其涉及一种资源分配方法、装置及系统。
背景技术
随着当前汽车行业的快速发展,第三代合作伙伴计划(Third Generation Partnership Project,3GPP)标准工作组为了将长期演进(Long Term Evolution,LTE)技术扩展至汽车行业,于2015年8月启动基于LTE系统的车联网标准化工作,并在2017年3月推出的R14版本3GPP协议中,对基于LTE的车联网(Vehicle-to-everything,V2X)(或译为:车辆对一切)通信标准进行了定义。其中,采用R14版本3GPP协议的终端根据资源分配方式的不同划分为mode3终端和mode4终端,mode3终端和mode4终端可用的资源池也被划分为独立的两部分。基站从资源池的第一部分中为mode3终端分配时频资源,而mode4终端从资源池的第二部分中随机选择时频资源或者通过监听Sensing方式自主选择时频资源。
为了提高对资源的利用效率,在R15版本的3GPP协议中,mode3终端和mode4终端共享资源池中的资源。但是,由于基站在为mode3终端分配资源时,并不能确定mode4终端自主选择了哪些资源。因此为了减少资源冲突、防止基站从共享资源池中为mode3终端分配的资源也被mode4终端使用,采用R15版本的mode3终端也可以通过Sensing的方式确定可用资源并向基站上报,基站根据R15版本的mode3终端上报的可用资源为R15版本的mode3终端分配资源。
但是在现有技术中,采用R14版本3GPP协议的终端和采用R15版本3GPP协议的终端同时存在并共用资源池。其中,采用R14版本的终端将资源池根据mode3终端和mode4终端划分为两部分,而采用R15版本的mode3终端和mode4终端则共享该资源池中的资源。因此会造成基站在为不能确定可用资源的R14版本的mode3终端分配资源时,仍然存在发生资源冲突的可能。

具体实施方式
图1为本申请实施例应用的通信系统结构示意图。如图1所示的应用场景中,系统10可以包括网络设备101以及终端设备102,103和104。其中,网络设备与终端设备之间、终端设备与终端设备之间都可以通过无线连接。应理解,图1仅以系统包括三个终端设备为例进行说明,但本发明实施例并不限于此,例如,系统还可以包括更多的终端设备;类似地,系统也可以包括更多的网络设备。还应理解,系统也 可以称为网络,本发明实施例对此并不限定。如图1所示,终端设备之间可以进行端到端通信。
下面以车联网为例,介绍本申请的通信方法在车联网中的具体实现方式。若图1所示的系统为车联网系统,则网络设备对终端设备进行调度,并将调度结果发送至该网络设备覆盖范围内的终端设备,其中,该场景下,终端设备指的是车联网中的车辆,或者终端设备还可以指车联网中处于终端角色的基础设施,或者终端设备还可以指车联网中个人携带的设备,例如,行人、骑行者、司机、乘客携带的手持设备。终端设备还可以指其他车联网中的道路使用者或道路使用者携带的设备。图1所示的应用场景中,终端设备之间可以进行D2D通信。第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的版本14(Release14)定义了基于D2D链路增强的V2X链路(例如可以包括以下链路中的至少一种:V2V、V2I、V2P链路)。D2D链路和V2X链路可以采用不同的接口进行通信。图1所示的应用场景中,终端设备与终端设备之间通信的链路可以称为侧行链路(sidelink)。
应理解,在本申请实施例的车联网中,终端设备可以是安装在汽车里面的通信终端或车载通信设备,还可以是其它能够实现通信功能的模块化、可拆卸的车载终端。终端设备在功能上要能够实现车与车(Vehicle to Vehicle,V2V)、人与车(Vehicle to Pedestrain,V2P)、车与基础设施(Vehicle to Infrastucture,V2I)等业务的信息通讯,这些业务可以统称为V2X业务。因此,本申请实施例中的V2X业务可以包括以下业务中的一种或多种:V2V业务、V2I业务、车与人V2P业务。具体地,如图1所示的车联网通信系统包括基站eNB和至少一个车联网通信终端设备(如图1中的终端A、终端B和终端C均为携带在汽车上的车联网通信终端设备),每个车联网通信终端设备通过无线的方式与基站和其他终端相连并通信。终端设备也可以称为终端Terminal、用户设备(user equipment,UE)、移动台(mobile station,MS)、移动终端(mobile terminal,MT)等。其中,终端A和终端B处于基站的网络覆盖范围内,可以直接与基站进行通信;终端C处于基站eNB的网络覆盖范围外,不能直接与基站进行通信;终端A、B和C之间在通信范围之内可以相互通信,还可以与各自信号覆盖范围内的其他终端进行通信并且不需要经由基站或其他终端转发。
在R14版本的3GPP协议中,车联网通信系统中的UE按照资源分配模式分为mode3 UE和mode4UE两种类型。同时,UE进行V2X通信时可用的时频资源的资源池也被划分为独立的两部分,分别分配给mode3 UE和mode4 UE使用。例如:图2A为采用R14版本3GPP协议的UE的资源池的结构示意图。图中UE在进行V2X通信时可用的时频资源的频段为A-B,根据纵轴的频率划分的A-C部分为mode3UE部分,划分的C-B部分为mode4 UE部分。其中,基站从资源池的mode3 UE部分中为mode3 UE分配V2X通信时使用的时频资源,而mode4 UE从资源池的mode4 UE部分中随机选择时频资源或者通过监听Sensing方式自主选择时频资源。具体地,当mode3 UE向基站请求分配资源时,基站根据资源池内mode3 UE部分的空闲资源,向该mode3 UE分配可用的时频资源。由于所有mode3 UE的时频资源都由基站分配,基站知道整个mode3 UE部分资源池的资源使用情况,知道哪些资源已被占用、哪些资源未被占用,因此mode3 UE部分的资源池内的资源不会产生资源冲突。同时,mode4 UE可以通过监听/感知Sensing的方式,监听mode4 UE部分的资源池内哪些资源被占用、哪些资源未被占用,并根据Sensing结果选择可用资源,因此mode4 UE部分的资源池内的资源也不会产生显著的资源冲突问题。
但是,在R14版本的3GPP协议中,将资源池按照UE资源分配模式划分为两部分时对资源的利用效率并不高。例如,当车联网通信系统内mode3 UE数量较少、mode4 UE数量较多时,mode4 UE部分的资源池内因为有大量mode4 UE使用资源而导致资源拥塞,而mode3 UE部分的资源池内的资源却没有得到充分利用造成了资源浪费;而当车联网通信系统内mode 3 UE数量较多、mode4 UE数量较少时,基站用于向mode3 UE分配的资源有限,基站在调度时会导致传输时延,而在mode4 UE部分的资源池内的资源却没有得到充分利用造成了资源浪费。
因此,为了提升资源的使用效率,减少资源浪费和资源拥塞,在R15版本的3GPP协议中,mode3UE和mode4 UE共享资源池。例如:图2B为采用R15版本3GPP协议的UE的资源池的结构示意图,图中UE通信时可用的时频资源的频段为A-B,与R14版本的3GPP协议中相同,并且将图2A中资源池的mode3 UE部分和mode4 UE部分合并作为一个共享资源池整体而不进行A-C与C-B部分的划分。其中,基站从共享资源池的中为mode3 UE分配资源,而mode4 UE也从该共享资源池中随机选择资源或者通过监听Sensing方式自主选择资源。同时,为了防止基站在给mode3 UE分配的共享资源池中的资源同时被mode4 UE所使用而产生冲突,采用R15版本3GPP协议的mode3 UE也具备Sensing功能,并通过Sensing得到可用资源后上报基站,基站基于采用R15版本3GPP协议的mode3 UE上报的Sensing结果向其分配资源。
但是,现有的车联网通信系统中,并不是所有UE都采用R15版本的3GPP协议,而是采用R14版本3GPP协议的UE和采用R15版本3GPP协议的UE同时存在。并且,采用R14版本3GPP协议的UE和采用R15版本3GPP协议的UE共用资源池。其中,采用R14版本的UE依然根据mode3 UE和mode4UE将资源池划分为两部分并分别使用,而采用R15版本的mode3 UE和mode4 UE则共享该资源池中的资源。因此会造成基站在为R14版本的mode3终端配置资源时,不能确定分配的资源是否被R15版本的mode4终端所使用,仍然存在资源冲突的可能。
因此,本申请提供一种资源配置方法及装置,以减少在基于LTE的车联网通信系统中,基站在为UE分配资源时资源冲突的可能。
具体地,图3为本申请资源分配方法实施例一的流程示意图。如图3所示的本实施例的资源配置方法实施例一中,S101、基站获取第一终端的监听/侦查Sensing结果、第一终端的位置信息和第二终端的位置信息;S102、若第一终端的位置信息和第二终端的位置信息满足预设条件,则基站根据第一终端的Sensing结果为第二终端分配第二资源。
其中,在本实施例中,第二终端和第一终端均为图1所示的车联网通信系统中的终端,其中,第一终端具备Sensing的功能,即能够通过Sensing结果确定第一终端的可用资源。并可以使得基站根据第一终端的Sensing结果为第一终端分配第二资源,或者,第一终端能够根据Sensing结果自主选择资源。而第二终端不具备Sensing的功能,即基站在为第二终端分配通信所使用的资源时,基站不能确定哪些资源未被其他终端使用从而可以分配给第二终端。较佳地,本实施例应用于车联网通信系统时,上述资源指终端通信时可用的时频资源,即基站向第二终端分配用于V2X通信时使用的第二资源。此外,本申请中基站向第二终端分配的资源也可以是时域资源、频域资源、广播资源或者其他类型的资源。
因此,为了避免基站给第二终端分配的资源与其他终端正在使用的资源产生冲突,基站可以在第一终端和第二终端的位置信息满足预设条件的情况下,根据第一终端通过Sensing得到的Sensing结果中确定第一终端的可用的资源,并从中分配第二资源给第二终端在V2X通信时使用。从而保证了基站向不能通过Sensing确定可用资源的第二终端分配资源时,能够将第一终端通过Sensing确定的可用的资源分配给第二终端,减少了基站在分配资源时发生资源冲突的可能。
可选地,第二终端还可以是具备Sensing功能、但是由于功能调整或者故障等原因暂时不能Sensing的终端。则基站也可以在确认第二终端暂时不能Sensing后,根据第一终端的Sensing结果给第二终端分配资源。
可选地,第二终端可以在S101之前向基站发送资源分配请求,用于请求基站为第二终端分配通信时使用的资源。其中,发送的资源分配请求可以是缓存状态报告(Buffer Status Report,BSR),BSR用于通知基站UE当前有多少数据需要发送,即通知基站需要给UE分配的资源的资源大小。
其中,Sensing结果用于指示第一资源的使用情况,其中,第一资源为终端到终端通信所使用的资源。 应用于车联网通信系统中,资源为车联网系统内基站可为终端分配的资源池中的所有用于终端到终端通信所使用的时频资源,Sensing结果用于指示在Sensing范围内系统的终端在进行终端到终端通信例如V2X通信时使用的时频资源的使用情况。例如:在车联网系统中,基站可从一时频资源池内为某小区内的终端分配资源,则该小区内的任意终端A需要请求基站为其分配资源时,终端A通过Sensing获取在该小区内的时频资源池中已经被使用的资源、并明确终端A此时可用的资源使用情况后,向基站上报Sensing结果;使得基站能够根据Sensing结果为终端A分配时频资源池内此时终端A可用的时频资源。可选地,在上述实施例中,第一终端的Sensing结果中具体可以包括以下的一项或多项:第一资源中的特定资源、第一资源的信号强度、第一资源上的信号功率和第一资源的信道占用比,其中,特定资源为可用资源或不可用资源,即通过不可用资源来表示可用资源,基站在资源池中除去不可用资源的部分即为可用资源。从而使得基站可以根据第一终端的Sensing结果从第一资源中为第二终端分配第二资源。进一步地,第一资源包括第二资源。例如:当Sensing结果中包括了第一终端的三部分可用第一资源,三部分可用的第一资源其中之的部分为第二资源,则基站从三部分中确定第二资源可以分配给第二终端进行终端到终端的通信;而当Sensing结果中包括了第一终端不可用的部分资源,则基站从不可用资源外的其他资源中确定第二终端的可用的第二资源;当Sensing结果中包括多部分特定资源时,还可携带第一资源的信号强度、第一资源上的信号功率和第一资源的信道占用比,使得基站根据第一资源的上述参数,从第一资源中确定信号较强或者通信情况最好的资源作为第二资源分配给第二终端进行终端到终端通信时使用。
较佳地,上述实施例中第二终端是采用R14版本3GPP协议的mode3 UE,第一终端是采用R15版本3GPP协议的mode3 UE。
例如,图4为本申请资源分配方法中终端位置实施例一的结构示意图。如图4所示的一种车联网系统结构中,基站eNB范围内包括了四个UE标号分别为A、B、C和D。其中,UE A为采用R15版本3GPP协议的mode3 UE;UE B为采用R14版本3GPP协议的mode3 UE;UE C为采用R15版本3GPP协议的mode4 UE;UE D为采用R14版本3GPP协议的mode4 UE。UE C和UE D不需要请求基站分配资源,通过Sensing方式自主选择可用的资源后,在图4所示的车联网系统中进行V2X通信。UE A可以通过Sensing方式监听可用资源后,向eNB发送资源分配请求并携带Sensing结果,使得eNB根据UE A上报的Sensing结果为UE A分配用于V2X通信的资源。而UE B不具备Sensing的能力因此只能向eNB发送资源分配请求后,由eNB为其分配资源。
则在图4的实施例中应用本申请实施例一的方法,在eNB向UE B分配资源之前,先获取UE A通过Sensing监听并上报的Sensing结果,Sensing结果中包括了UE A的可用资源。假设UE A在其能力范围内通过Sensing确定,UE C通信时使用了频段1、UE D通信时使用了频段2,而可用资源池中例如还包括了频段3和频段4。则UE A发送至eNB的Sensing结果内包括其监听到的可用资源频段3和频段4。由于车联网通信中各个UE之间也会进行通信,并且UE C和UE D自主选择可用的通信资源,因此eNB并不能确定目前资源池中哪些资源被UE C和UE D占用。故eNB根据UE A上报的可用资源为频段3和频段4确定目前UE A的可用资源为频段3和频段4,并当第一终端的位置和第二终端的位置满足预设条件,则从中确定例如频段3为第二资源,将频段3分配给UE B在该图4所示的车联网通信系统中进行V2X通信时使用。
需要说明的是,UE A向eNB上报的Sensing结果中可包括多个可用资源,eNB可以从中任意分配第二资源给UE B,也可以根据UE B的实际情况确定最合适的第二资源。
此外,eNB还可以在给UE B分配资源前、分配资源后或者同时根据UE A上报的可用资源为UE A分配V2X通信时所使用的第二资源。
综上,本实施例提供的资源分配方法,在不具备Sensing能力的第二终端请求基站为其分配资源时,如果第二终端的位置与第一终端的位置满足预设条件,通过具备Sensing能力的第一终端Sensing结果,为第二终端分配用于通信所使用的第二资源。从而减少了车联网系统中基站在为不具备Sensing能力的第二终端分配资源时发生资源冲突的可能。
进一步地,在上述实施例中,第一终端的位置和第二终端的位置需要满足的预设条件可以是:
1、第一终端的位置与第二终端的位置之间的距离差小于第一阈值。或者,
2、第一终端的位置与第二终端的位置之间的距离差小于第一阈值;并且,第二时刻与第一时刻的时间差绝对值小于第二阈值。其中,第二时刻是第二终端向基站上报发送第二终端的位置信息的时刻,第一时刻是第一终端向基站上报发送第一终端的位置信息的时刻。
具体地,在上述预设条件实现方式1中,基站可以考虑将与第二终端位置相近的第一终端的Sensing结果用于给第二终端分配资源。其中,由于在车联网通信系统中每个终端都可以与基站和一定范围内的其他终端通信,但是基站并不能完全确定每个终端V2X通信时使用的时频资源。因此需要终端通过Sensing确定该终端的一定位置范围内,其他终端与基站、终端与终端之间V2X通信所使用的时频资源并上报基站,从而使得基站根据终端上报的Sensing结果为该终端分配可用的时频资源。同时,由于终端进行V2X通信的范围以及Sensing的搜索范围有限,终端的Sensing结果只是在有限的位置范围内得到,而基站根据该有限范围内的Sensing结果为该终端分配的时频资源已经可以保证该终端在V2X通信范围内不会与其他终端的时频资源产生冲突。
因此,基站在为根据第一终端Sensing结果为第二终端分配资源时,考虑第二终端与第一终端之间位置关系。例如,在本实施例中,第一终端具备Sensing功能,若假设第二终端与第一终端位置相近,之间的距离小于第一阈值时,则第一终端的Sensing结果可被认为是第二终端的Sensing结果并被基站用于为第二终端分配时频资源。
例如:在图4所示的实施例中,eNB在接收到UE B的资源分配请求后,获取UE B的位置、UE A的位置以及UE A上报的Sensing结果,并判断UE A和UE B之间的距离差为l1,此时若l1小于第一阈值,则eNB判断UE A的Sensing结果对UE B可用。相应地,图5为本申请资源分配方法中终端位置实施例二的结构示意图;在图5所示的实施例中,eNB判断UE A和UE B之间的距离差为l2,此时若l2大于第一阈值,则eNB判断UE A的Sensing结果对UE B不可用。
可选地,在实际应用中,第一阈值的大小可调。具体可以是基站配置的、预配置的、在协议中定义的,也可以根据基站的通信覆盖范围、终端的通信覆盖范围进行实时调整。较佳地,第一阈值的大小可以是50米或者100米。
可选地,本申请各实施例中判断第二终端的位置信息与第一终端的位置信息是否满足预设条件的步骤可以由基站执行,或者由基站将第二终端的位置信息与第一终端的位置信息发送至其他第三方服务器进行判断,本申请对于预设条件的判断方式不做具体限定。
具体地,在上述预设条件实现方式2中,基站不仅考虑1中第二终端的位置与第一终端位置之间的距离之差需要小于第一阈值。还需要同时确定第二终端上报位置的时刻与第一终端上报位置的时刻之间的时间之差小于第二阈值。二者同时满足时,基站才认为第一终端的Sensing结果对第二终端可用。其中,由于车联网通信系统中终端的移动性强、移动速度快,终端向基站上报位置信息后可能在很短时间便移动至下一位置,使得基站所接收的终端上次上报的位置不准确。而在本申请上述实施例中,如果第二终端和第一终端朝相反方向运动,则更会造成第一终端的Sensing结果在很短的时间内对第二终端不可用。因此,在本实施例中,基站在为根据第一终端Sensing结果为第二终端分配资源时,除了考虑第二终端与第一终端之间位置关系,还需要考虑第二终端上报位置信息的第二时刻与第一终端上报位置信 息的第一时刻之间的时间差。
例如,在本实施例中,第一终端具备Sensing功能,若假设第二终端与第一终端位置相近,之间的距离小于第一阈值时,则第一终端的Sensing结果可被认为是第二终端的Sensing结果并被基站用于为第二终端分配时频资源。图6A为本申请资源分配方法中第一时刻与第二时刻实施例一的示意图;在图6A所示的实施例中,第二终端在t1时刻向基站上报了第二终端的位置信息,第一终端在t2时刻向基站上报了第一终端的位置信息,为了使上报的位置信息具有时效性,则如果t1和t2时刻之间差的绝对值|t2-t1|小于第二阈值,则判断第一终端的Sensing结果对第二终端可用。相应地,图6B为本申请资源分配方法中第一时刻与第二时刻实施例二的示意图,在图6B所示的实施例中,第一终端在t1时刻向基站上报了第一终端的位置信息,第二终端在t2时刻向基站上报了第二终端的位置信息,为了使上报的位置信息具有时效性,则如果t1和t2时刻之间差的绝对值|t2-t1|小于第二阈值,则判断第一终端的Sensing结果对第二终端可用。
其中,上述实施例中仅对基站获取的第二终端上报的位置信息和第一终端上报的位置信息的时刻之间关系作出限定。而对于第二终端,可以在向基站发送资源分配请求之后或者同时向基站上报第二终端的位置信息;以及对于第一终端,可以在向基站发送Sensing结果之前、之后或同时上报第一终端位置信息的关系,具体的操作流程可通过本申请下文所述的终端上报位置信息的实施例中的顺序实现。
可选地,在如图6A所述的实施例中,基站在获取第二终端的位置信息后,还需等待至少第二阈值的时间等待第一终端发送其位置信息和/或Sensing结果。而在如图6B所示的实施例中,基站在获取第二终端的位置信息后,需要从之前的时刻至少第二阈值的时间内获取第一终端之前已经发送至基站的第一终端的位置信息和/或Sensing结果,基站可以通过存储设备对第一终端上报的位置信息进行存储。
或者,可选地,基站在等待至少第二阈值的时间后未收到第一终端发送的位置信息,则获取在第二终端发送位置信息之前第二阈值时间内的第一终端发送的位置信息。
可选地,在上述各实施例中,基站获取第二终端的资源分配请求以及位置信息后,可以获取多个第一终端的位置信息和Sensing结果,对每个第一终端的位置信息进行判断后,选择将最合适的第一终端的Sensing结果用于为第二终端分配资源。例如选择距离第二终端最近的第一终端、Sensing结果中包含的可用资源最多的第一终端等。
进一步地,在上述实施例中,第二阈值根据第二终端的业务优先级确定。其中,依次递增的业务优先级对应的第二阈值依次递减。
具体地,对于优先级较高的业务,第二终端需要保证其通信质量,基站则需要在向第二终端分配资源时,保证分配的资源最大可能地不与其他资源产生冲突。因此,基站根据较小的第二阈值对第一终端与第二终端的位置信息进行判断,只有当第一终端的位置与第二终端的位置距离较近、且上报的时间间隔较小时,才能保证第一终端的Sensing结果中包含有效的资源。例如:将第二终端需要通信的业务优先级分为高中低三级,分别对应的第二阈值可以是10毫秒、20毫秒和30毫秒。第二终端可以在资源分配请求中携带所请求资源的业务优先级。较佳地,各实施例中的第二阈值可以设置为4-20毫秒。
综上,本实施例通过对第一终端的位置信息和第二终端的位置信息进行时效性的判断,使得基站确定满足预设条件的第一终端的Sensing结果可用于对第二终端分配时频资源。在减少车联网系统中基站在为不具备Sensing能力的第二终端分配资源时发生资源冲突的可能的同时,能够确保资源的有效性和实时性,从而进一步减少了资源冲突的可能。
进一步地,为了保证本申请保证各实施例中基站获取第二终端的位置信息、基站获取第一终端的位置信息的时效性。本申请还在上述实施例的基础上,使第二终端以及第一终端通过如下所述的终端上报位置信息的方式向基站发送各自的位置信息。具体地,本申请提供的终端向基站上报发送位置信息的方 法包括:
1、基站接收到第二终端发送的资源分配请求后向第二终端发送位置请求,第二终端根据接收到基站发送的位置请求向基站上报第二终端的位置信息和/或基站接收到第一终端发送的Sensing结果后向第一终端发送位置请求,第一终端根据接收到基站发送的位置请求向基站上报第一终端的位置信息。
具体地,基站可以在接收到第二终端发送的资源分配请求或接收到第一终端发送的Sensing结果发送位置请求,请求第二终端或第一终端再次向基站上报其位置。可以理解的是,第二终端和第一终端在此之前均已向基站上报过位置信息,而为了保证第二终端和第一终端位置信息的实时性,基站在需要时再次请求终端上报位置信息。其中,资源分配请求可以以信令的方式由基站下发至终端。
2、第二终端配置为发送资源分配请求后,即向基站发送第二终端的位置信息和/或第一终端被配置为发送Sensing结果后,即向基站发送第一终端的位置信息。
具体地,现有的位置信息上报方式为,基于小区下行参考信号RSRP的事件触发上报。其中,基站先向UE发送一个测量报告配置,报告配置中包含了上报准则和UE需要上报的信息。上报准则包括周期上报和事情触发上报,只有当上报的目的为上报StrongestCells或者上报CGI时,UE才会周期性上报测量报告,其他情况则为事件触发上报。当触发以下事件时:
Event A1:Serving becomes better than absolute threshold;
Event A2:Serving becomes worse than absolute threshold;
UE会向基站上报一个测量报告,位置信息包含在测量报告中。但是,由于Event A1和Event A2这两种事件的发生具有很大的随机性且需要较长时间,这种上报位置信息的方式无法保证时效性。
因此,在本实施例中,考虑在ReportConfig中添加新的触发事件。把UE向基站上报了Sensing结果作为一个触发UE上报测量报告的事件(Event B2),当UE向基站上报Sensing结果后,根据ReportConfig中的新添加的Event B1,会触发UE上报测量结果。
Event B1:UE reports sensing result to eNB;
把UE向基站发送了资源分配请求(这里资源分配请求为BSR)作为一个触发UE上报测量报告的事件(Event B2),当UE向基站上报BSR后,根据ReportConfig中的新添加的Event B2,会触发UE上报测量结果。
Event B2:UE reports BSR to eNB。
本实施例中UE上报位置信息的方法可以使得UE向基站上报sensing或者BSR后立即上报位置信息的效果,保证了位置信息的实时性。
3、第一终端和/或第二终端周期性地向基站上报位置信息。
具体地,第一终端和第二终端都可以通过周期性上报测量报告的方式,在测量报告中携带终端的位置信息。其中,要求上报的目的为reportStrongestCells,reportCGI,如下所示:
Figure PCTCN2019082406-appb-000001
此方案考虑在上报目的中添加“上报位置信息”,使UE周期性向基站上报位置信息。上报地周期可以在ReportConfig中预配置,基站根据UE最近一次上报地位置信息来判断UE的地理位置。
Figure PCTCN2019082406-appb-000002
Figure PCTCN2019082406-appb-000003
4、第二终端在资源分配请求中携带第二终端的位置信息和/或第一终端在Sensing结果中携带第一终端的位置信息。
具体地,本实施例将表示位置信息的字段locationInfo添加到资源分配请求或者Sensing结果中。当UE向基站上报资源分配请求或者Sensing结果时,位置信息会包含在Sensing结果或资源分配请求中被一起上报,无论UE是否将测量结果上报给基站,基站都能获知UE的位置信息。从而通过把表示位置信息的字段locationInfo添加到资源分配请求或者sensing结果中,保证了位置信息上报的时效性。
5、第二终端在向基站发送的第二BSR中携带第二终端的位置信息和/或第一终端在向基站发送的第一BSR中携带第一终端的位置信息。
具体地,本实施例将表示位置信息的字段locationInfo添加到BSR中。当UE向基站上报BSR时,位置信息会包含在BSR中被一起上报,无论UE是否将测量结果上报给基站,基站都能获知UE的位置信息。从而通过把表示位置信息的字段locationInfo添加到BSR中,保证了位置信息上报的时效性。
需要说明的是,上述终端向基站发送位置信息的各方法可单独使用或组合使用,并可根据基站以及终端的通信环境标准进行实时调整,在此不做限定。

为便于进一步理解,以下以R15 mode3 UE为上述实施例中所述的第一终端、R14 mode3 UE为上述实施例中所述的第二终端为例,示出一些具体的场景表述。
在一些具体的车联网通信系统场景中,对于R14 mode3 UE,基站给R14 mode3 UE分资源时,R14mode3 UE不会向基站上报可用资源,如果基站不知道R14 mode 4 UE或者R15 mode 4 UE使用的资源,则可能会造成资源冲突。
则在本申请另一具体实施例中,为了减少基站给R14 mode3 UE分配资源时可能产生的资源冲突,基站需要在给R14 mode3 UE分配资源时获得可用资源的信息,即没有被mode4UE占据的资源。由于R15 mode3 UE可以sensing并上报可用资源给基站,而R14 mode3 UE不可以;因此考虑基站利用地理位置信息,在给R14 mode3 UE分配资源时利用邻近区域的R15 mode3 UE上报的sensing结果,以此来减少资源冲突。流程概括如下:
1)R15 mode3 UE向基站上报sensing结果和位置信息
2)R14 mode3 UE向基站上报BSR和位置信息
3)基站接收R15 mode3 UE上报的sensing结果和位置信息以及R14 mode3 UE上报的BSR和位置信息
4)基站判断sensing结果是否可用
5)基站给R14 mode3 UE分配资源
上述流程中,1)和2)不分先后顺序。从而主要解决基站在给R14 mode3 UE分配资源时,如果不知道mode4UE使用的资源可能会造成资源冲突的问题。
如图13所示,图13为本申请资源分配方法另一实施例具体场景的流程示意图。R15 mode3 UE在t1时刻向基站上报sensing结果和地理位置,R14 mode3 UE在t2时间向基站上报BSR结果和地理位置,基站根据二者上报的地理位置判断二者地理位置是否邻近(见图14,图14为本申请资源分配方法另一实施例中终端位置实施例的结构示意图),当二者地理位置邻近且上报时间差t<k(见图15,图15为本申请资源分配方法另一实施例具体场景中上报地理位置时间差的示意图;)时,基站认为R15 mode3 UE上报的sensing结果对R14UE可用,即基站可以利用R15 mode3 UE上报的可用资源(即sensing结果)给R14 mode3 UE分配资源。
R15 mode3 UE上报的sensing结果是具有时效性的。如图5所示,R15 mode3 UE(记为UEA)在t1 时间向基站上报sensing结果,R14 mode3 UE(记为UEB)在t2时间向基站上报BSR。如果其它UE(记为UEC)在t1-t2这个时间段使用R15 mdoe3 UEsensing到的可用资源,那么在t2时UEA上报的sensing结果将对UEB不可用,因为这些资源已经被UEC使用了。UE上报的地理位置也具有时效性,V2X场景中UE在不断移动,如果t值较大,那么R15 mode3 UE和R14 mode3 UE的实际地理位置与上报的地理位置会相差较大,sensing结果也将不可用。因此需要对t做一个限制,当t<k时,sensing结果可用。图16为本申请资源分配方法另一实施例的流程示意图。如图6示出了基站通过先后判断R15mode3地理位置和R14 mode3地理位置是否接近以及时间t是否小于k来判断Sensing结果可用,两个条件中任一个条件不满足则Sensing结果不可用。
为了使上报的地理位置信息具有时效性,保证R15 mode3 UE上报的sensing结果对R14 mode3 UE是可用的,需要新设计位置信息上报方式,例如R15UE上报sensing和R14UE上报BSR时,都需要上报自己的地理位置信息。
现有的位置信息上报方式为基于小区下行参考信号RSRP的事件触发上报,如图17所示:图17为现有技术中终端上报位置信息的流程示意图。
基站首先向UE发送一个测量报告配置,报告配置中包含了上报准则和UE需要上报的信息。上报准则包括周期上报和事情触发上报,只有当上报的目的为上报StrongestCells或者上报CGI时,UE才会周期性上报测量报告,其他情况则为事件触发上报。当触发以下事件时:
Event A1:Serving becomes better than absolute threshold;
Event A2:Serving becomes worse than absolute threshold;
UE会向基站上报一个测量报告,位置信息包含在测量报告中,由于Event A1和Event A2这两种事件的发生具有很大的随机性且需要较长时间,这种上报位置信息的方式无法保证时效性。
因此,本申请在实施例一中,考虑在ReportConfig中添加新的触发事件。把UE向基站上报了sensing结果作为一个触发UE上报测量报告的事件(Event B2),当UE向基站上报sensing结果后,根据ReportConfig中的新添加的Event B1,会触发UE上报测量结果。
Event B1:UE reports sensing result to eNB;
把UE向基站上报了BSR作为一个触发UE上报测量报告的事件(Event B2),当UE向基站上报BSR后,根据ReportConfig中的新添加的Event B2,会触发UE上报测量结果。
Event B2:UE reports BSR to eNB。
此方案可以达到UE向基站上报sensing或者BSR后立即上报位置信息的效果,保证了位置信息的实时性。具体地,由于现有的位置信息上报方式为基于小区下行参考信号RSRP的事件触发上报,这一事件的触发有时需要经过较长时间,无法满足位置信息上报的时效性,而在此方案中,通过把上报sensing结果或者上报BSR结果作为触发UE上报测量报告的触发事件,可以在UE上报sensing结果或BSR后立即上报位置信息,保证了位置信息上报的时效性
在实施例二中,R15 mode3 UE上报sensing结果、R14 mode3 UE上报BSR和位置信息、基站判断上报信息是否可用过程与实施例一相同。本实施例主要讨论上报方式(周期报告)的修改。
除了事件触发UE上报测量报告,UE也可以周期性上报测量报告,但是要求上报的目的为reportStrongestCells,reportCGI,如下所示:
Figure PCTCN2019082406-appb-000004
Figure PCTCN2019082406-appb-000005
此方案考虑在上报目的中添加“上报位置信息”,使UE周期性向基站上报位置信息。上报地周期可以在ReportConfig中预配置,基站根据UE最近一次上报地位置信息来判断UE的地理位置。
Figure PCTCN2019082406-appb-000006
此方案通过周期性地向基站上报位置信息,在周期值配置为较小值地情况下,可以使位置信息上报具有一定的时效性。具体地,现有的位置信息上报方式为基于小区下行参考信号RSRP的事件触发上报,这一事件的触发有时需要经过较长时间,无法满足位置信息上报的时效性,而在此方案中,通过周期性地向基站上报位置信息,在周期值配置为较小值地情况下,可以使位置信息上报具有一定的时效性。
在实施例三中,类似实施例二,本实施例重点讨论如何在上报结果中携带位置信息。
此方案把表示位置信息的字段locationInfo添加到BSR或者sensing结果中。当UE向基站上报BSR或者sensing结果时,位置信息会包含在sensing结果或BSR中被一起上报,无论UE是否将测量结果上报给基站,基站都能获知UE的位置信息。
本实施例通过把表示位置信息的字段locationInfo添加到BSR或者sensing结果中,保证了位置信息上报的时效性。具体地,此方案通过把表示位置信息的字段locationInfo添加到BSR或者sensing结果中将位置信息的上报与测量结果的上报分离,无论UE是否将测量结果上报给基站,基站都能获知UE的位置信息。这一方案保证了位置信息上报的时效性。
综上,本实施例提出eNB利用位置信息给R14 mode3 UE分配资源,而该资源来自于R15 mode3 UE上报的sensing结果,从而减少了因R14 mode3 UE不能上报sensing结果而导致基站不知道mode4UE的资源使用情况造成的资源冲突,保护了R14 mode3 UE的性能。
其中,关键点包括:基站根据地理位置利用R15 mode3 UE上报的sensing结果给R14 mode3 UE分配资源,为了保证地理位置的时效性,设计新的地理位置上报方式。
次要关键点包括:sensing结果的可用条件,需要判断R15 mode3 UE和R14 mode3 UE是否地理位置邻近,以及R15 mode3 UE上报的sensing结果的时间t1和R14 mode3 UE上报的BSR的时间t2之间的时间差t,只有当二者地理位置接近且t值足够小时,sensing结果才可用。
