Description

信息处理方法、装置、基站、用户设备及存储介质 技术领域
本公开涉及无线通信技术领域,尤其涉及一种信息处理方法、装置、基站、用户设备及存储介质。
背景技术
车用无线通信技术(vehicle to Everything,V2X)使用用户间直传链路(Sidelink,SL)进行通信。与长期演进(LTE)V2X相比,新空口(new radio,NR)V2X可以支持更多应用场景,例如车辆组队驾驶、扩展传感、远程驾驶、增强驾驶等。为提供以上服务,NR V2X需要支持更高的传输可靠性和更低的通信时延,LTE V2X的资源分配方法已经不再适用,需要对资源分配方式进行进一步研究。
目前,针对NR V2X的资源分配方式主要有两种:基站集中调度方式和用户自主选择方式。其中,所述基站集中调度方式是指由基站控制SL资源池的使用,基站分配用户设备(User Equipment,UE)进行Sidelink传输所需要的SL资源;所述用户自主选择方式是指采用UE一定的资源冲突避免机制,自主地从资源池中选择sidelink传输所需要的SL资源。为了减少频谱资源的浪费,提高资源利用率,可以采用两种资源分配方式共享资源池;然而若上述两种资源分配方式共享资源池,会相互干扰、可靠性比较低。

请参考图1,其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示,无线通信系统是基于蜂窝移动通信技术的通信系统, 该无线通信系统可以包括:若干个用户设备110以及若干个基站120。
其中,用户设备110可以是指向用户提供语音和/或数据连通性的设备。用户设备110可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网进行通信,用户设备110可以是物联网用户设备,如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网用户设备的计算机,例如,可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如,站(Station,STA)、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程用户设备(remote terminal)、接入用户设备(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户设备(user equipment)。或者,用户设备110也可以是无人飞行器的设备。或者,用户设备110也可以是车载设备,比如,可以是具有无线通信功能的行车电脑,或者是外接行车电脑的无线用户设备。或者,用户设备110也可以是路边设备,比如,可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站120可以是无线通信系统中的网络侧设备。其中,该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication,4G)系统,又称长期演进(Long Term Evolution,LTE)系统;或者,该无线通信系统也可以是5G系统,又称新空口系统或5G NR系统。或者,该无线通信系统也可以是5G系统的再下一代系统。其中,5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network,新一代无线接入网)。
其中,基站120可以是4G系统中采用的演进型基站(eNB)。或者,基站120也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站120采用集中分布式架构时,通常包括集中单元(central unit,CU)和至少 两个分布单元(distributed unit,DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol,PDCP)层、无线链路层控制协议(Radio Link Control,RLC)层、媒体访问控制(Media Access Control,MAC)层的协议栈;分布单元中设置有物理(Physical,PHY)层协议栈,本公开实施例对基站120的具体实现方式不加以限定。
基站120和用户设备110之间可以通过无线空口建立无线连接。在不同的实施方式中,该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口;或者,该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口,比如该无线空口是新空口;或者,该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中,用户设备110之间还可以建立E2E(End to End,端到端)连接。比如车联网通信(vehicle to everything,V2X)中的V2V(vehicle to vehicle,车对车)通信、V2I(vehicle to Infrastructure,车对路边设备)通信和V2P(vehicle to pedestrian,车对人)通信等场景。
在一些实施例中,上述无线通信系统还可以包含网络管理设备130。
若干个基站120分别与网络管理设备130相连。其中,网络管理设备130可以是无线通信系统中的核心网设备,比如,该网络管理设备130可以是演进的数据分组核心网(Evolved Packet Core,EPC)中的移动性管理实体(Mobility Management Entity,MME)。或者,该网络管理设备也可以是其它的核心网设备,比如服务网关(Serving GateWay,SGW)、公用数据网网关(Public Data Network GateWay,PGW)、策略与计费规则功能单元(Policy and Charging Rules Function,PCRF)或者归属签约用户服务器(Home Subscriber Server,HSS)等。对于网络管理设备130的实现形态,本公开实施例不做限定。
目前,V2X中使用SL进行通信,主要采用以下两种方式进行资源分配:
第一种方式,如图2所示,本公开一实施例提供了一种基站集中调度方式的资源分配方法。请参见图2,第一用户设备UE向所述基站发送用户间直传链路SL的缓存状态报告(Buffer State Report,BSR);所述基站基于所述BSR,为所述第一UE分配SL资源,并向所述第一UE发送资源分配(resource allocation,RA)信息;所述第一UE基于所述SL资源向第二UE发送信息;其中,所述信息包括直传链路控制信息(Sidelink Control Information,SCI)和/或数据(data)。
在一实施例中,如图3所示,所述一种基站集中调度方式的资源分配方法,包括以下步骤:
S01,第一UE向基站发送SL的BSR;
S02,所述基站基于所述BSR,向所述第一UE发送调度信息;其中,所述调度信息包括SL资源;
S03,所述第一UE基于所述SL资源向所述基站发送信息,其中,所述信息包括SCI和/或数据。
第二种方式,如图4所示,本公开一实施例提供了一种基于用户设备UE自主选择方式的资源分配方法。请参见图4,第一UE从基站的预配置的资源池中选择进行SL传输所需要的SL资源;并基于所述SL资源向第二UE发送信息;其中,所述信息包括SCI和/或数据。
图2和图4中示出的两种方式中使用的资源池之间相互独立,互不干扰。为了减少资源的浪费、提高资源的利用率,可使得上述两种方式共享资源池;如此,在上述两个资源池共享资源池,需要减少两种资源分配间相互干扰。
如图5所示,本公开实施例中提供一种信息处理方法,所述方法包括:
步骤S11,接收第一用户设备UE发送的缓存状态报告BSR;
步骤S12,基于所述第一UE的数量和/或所述BSR,向相应的所述第 二UE发送调度信息;
步骤S13,根据接收到的所述第二UE基于所述调度信息上报的直传链路SL资源感知信息,为所述第一UE分配SL资源。
本公开实施例所述的信息处理方法,应用在基站中。这里,所述基站为用户设备接入互联网的接口设备。所述基站可以为各种类型的基站,例如,3G基站、4G基站或5G基站。
在本公开实施例中,所述第一UE为发送端UE;所述第二UE为接收端UE。这里,所述第一UE、和所述第二UE均为所述基站的信号覆盖范围下的UE。可以理解的是,所述第一UE和所述第二UE可以互换,在其它实施例中,若所述第二UE需要发送数据和/或控制信息给所述第一UE,则所述第二UE为发送端UE,所述第一UE为接收端UE。
这里,所述第一UE和所述第二UE均可以是移动电话、计算机、服务器、收发设备、平板设备或医疗设备,等等。
这里,所述第一UE和所述第二UE均可以为一个或多个UE。
在一些实施例中,所述第一UE的数量为与所述基站连接的所述第一UE的数量,或者,所述第一UE的数量为向所述基站发送所述BSR的所述第一UE的数量。
在一实施例中,所述接收第一用户的UE发送缓存状态报告BSR,包括:接收所述第一用户设备基于业务需求发送的缓存状态报告BSR。其中,所述业务可包括:周期性业务和/或非周期性业务。周期性业务为周期性定期传输的业务;非周期性业务可为不定期传输的业务。
在一些实施例中,所述BSR携带所述第二UE的标识信息,以通知基站该BSR所相应的第二UE。当然,标识出第二UE的方式可以有很多种,本公开的所有实施例并不对此做出限定。
例如,在一实施例中,所述BSR中携带所述第二UE的标识信息;其 中,所述标识信息用于指示相应的所述第二UE。
在一实施例中,所述第二标识信息可以为目的索引。可以理解的是,所述BSR中包括媒体存取控制(Media Access Control Address,MAC)单元;其中,所述MAC单元包括目的索引字段;其中,所述目的索引字段如下表1,包括:目的索引1、目的索引2、……目的索引N-1,目的索引N;其中,所述N为大于或等于1的自然数。这里,一个目的索引字段标识一个第二UE,如此,在本公开实施例中,基站可以基于所述目的索引字段确定相应的第二UE,并向所述第二UE发送调度信息。

表1 MAC单元示意表
当然,在其它实施例中,所述标识信息也可以为其它的数字、字母和/或字符等,所述标识信息可以唯一标识所述第二UE或者所述基站信号覆盖范围内的UE的任何信息,具体的消息内容在此不作限制。
在一实施例中,所述基站基于物理上行共享信道(Physical Uplink Shared Channel,PUSCH)接收所述第一UE发送的所述BSR。
这里,所述SL资源感知信息包括但不限于以下至少之一:各UE占用资源池的资源信息、及所述第二UE可用的资源信息。
这里,所述向所述第二UE发送调度信息,包括:基于所述物理下行(Physical Downlink Control Channel,PDCCH)和/或物理下行共享信道 (Physical Downlink Shared Channel,PDSCH)发送调度信息。
可以理解的是,所述第二UE可以基于能量感知,以确定所述SL资源感知信息。例如,在SL监听,若有其他设备占用了某一个SL资源,则会收到在该SL资源上传输的无线信号,从而生成SL资源感知信息。
在一些实施例中,所述方法还包括:
向所述第一UE发送用于指示为所述第一UE分配的SL资源的分配信息。
这里,向所述第一UE发送SL资源的分配信息,包括:所述基站通过下行链路控制信息(Downlink Control Information,DCI)format 5A,向所述第一UE发送分配信息。如此,所述第一UE可以通过对所述DCI farmat5A解码,以获得所述SL资源。
这里,所述SL资源包括但不限于以下之一:SL时域资源、及SL频域资源。
在本公开实施例中,当基站接收到第一UE发送的BSR,可以向第二UE发送调度信息,以使得所述基站获取所述第二UE上报的SL能量感知信息,并基于所述SL能量感知信息,向所述第一UE发送SL资源的分配信息。如此,在本公开实施例中,一方面可以实现基站基于所述第一UE上报的BSR为所述第一UE分配SL资源;另一方面可以实现第二UE根据自身确定的SL资源感知信息自主选择SL资源;使得这两种分配方式可以共用所述基站的SL资源(即资源池的SL资源)。且,由于基站能够从第二UE中,及时了解到SL资源被占用情况,从而可以减少由于基站给UE分配SL资源或所述UE自主选择资源时的相互干扰,可以在大大提高SL资源的利用率的前提下,提高基于SL传输数据和/或控制信息的可靠性。
在一些实施例中,所述第二UE基于所述调度信息上报的SL资源感知信息中至少包括:
所述第二UE基于所述调度信息上报的空闲SL资源的信息。
这里,所述空闲SL资源包括但不限于以下之一:空闲SL时域资源、及空闲SL频域资源。
在一些实施例中,所述接收到所述第二UE基于所述调度信息上报的直传链路SL资源感知信息,包括:
接收所述第二UE感知的空闲SL资源的信息。
在一实际应用中,基站的资源池包括多个SL资源;这里所述SL的信息可以为所述SL在所述资源池的SL资源位置。当然,在其它实际应用中,所述SL资源信息也可以为标识所述SL资源的标识信息。
在本公开实施例中,所述第二UE可以仅上报所述第二UE感知的SL资源的信息,例如:空闲SL时域资源、或空闲SL频域资源。如此,所述基站也可以仅接收空闲SL资源的信息。相对于接收整个SL资源占用情况信息来说,能够减少所述第二UE上报所述SL资源的信息。且,由于上报的信息更少,也能够减少所述第一UE获得分配信息的等待时延。
在一些实施例中,所述空闲SL资源包括:空闲SL频域资源;其中,一个所述频域资源包括一个或多个子信道,且每一个所述子信道包括一个或多个频域资源块。
在另一些实施例中,所述空闲SL资源包括:空闲SL时域资源;其中,一个所述时域资源包括一个或多个传输时间间隔,且每一传输时间间隔内包括一个或多个时域资源块。
在一实施例中,所述子信道包括5个频域资源块。
在一实施例中,所述子信道包括的预定频域资源块小于或等于10个频域资源块。如此,可以在缩小所述第一UE等待时延的前提下,还能保证传输数据的可靠性。
在一实施例中,所述一个传输时间间隔(Transmission Time Interval, TTI)为1ms。
在实际应用中,发送频域资源信息的最小单位(也称为粒度)一般是一个频域资源块,和/或,发送频域信息的粒度一般是一个时域资源块。而在本公开实施例中,所述一个频域资源包括一个子信道,一个所述子信道包括一个或多个的频域资源块,和/或,所述一个时域资源包括一个传输时间间隔内的时域资源块。如此,在本公开实施例中,所述SL资源的信息可以以预定个数的频域资源块的粒度发送频域资源,和/或以一个传输时间间隔的粒度发送时域资源。如此,本公开实施例可以进一步缩短所述空闲SL时域资源或空闲SL频域资源的上报时间,从而进一步减少所述第一UE等待所述基站为所述第一UE分配资源的等待时间。
在一些实施例中,所述基于所述第一UE的数量和/或所述BSR,向相应的第二UE发送调度信息,包括:
根据所述第一UE的数量和/或所述BSR,向所述第二UE发送包含上报数量指示的所述调度信息,其中,所述上报数量指示,用于指示所述第二UE上报感知的SL资源位置的数量。
在本公开实施例中,SL资源位置是指;SL时域资源位置和/或SL频域资源位置。
在一些实施例中,所述若所述第一UE的数量达到第一状态和/或所述BSR达到第二状态,所述上报数量指示,用于指示所述第二UE上报第一数量的SL资源位置;
或者,
若所述第一UE的数量未达到第一状态,所述上报数量指示,用于指示所述第二UE上报第二数量的SL资源位置;
或者,
若所述BSR未达到第二状态,所述上报数量指示,用于指示所述第二 UE上报第二数量的SL资源位置;
其中,所述第二数量小于所述第一数量。
其中,所述第一UE的数量达到第一状态,包括
发送所述BSR的所述第一UE的数量达到第一数量阈值;
所述BSR达到第二状态,包括:
所述BSR指示的缓存数据量达到第一数据量阈值。
这里,若发送所述BSR的所述第一UE的数量达到第一数量阈值,则指示第二UE上报SL资源位置的数量为第一数量;若发送BSR的所述第一UE的数量未达到所述第一数量阈值,则指示第二UE上报SL资源位置的数量为第二数量。
在一实施例中,所述发送SL资源位置的第一数量等于所述第一UE的数量。
在另一实施例中,所述发送SL资源位置的第一数量大于所述第一UE的数量。其中,部分第一UE对应一个SL资源位置,另外部分第一UE对应2个或2个以上SL资源位置。
类似的,还可以根据所述BSR指示的缓存数据量来确定指示第二UE上报SL资源位置的数量。例如:若所述BSR指示的缓存数据量达到第一数据量阈值,则指示第二UE上报的SL资源位置的数量为第一数量;若所述BSR指示的缓存数量未达到第一数据量阈值,则指示第二UE上报SL资源位置的数量为第二数量。
如此,在本公开实施例中,基站根据与所述基站连接的UE数量,和/或发送BSR的所述第一UE的数据量,和/或所述BSR指示的缓存数据量,相应的要求第二UE发送SL资源位置的数量。
具体地,若与基站连接的UE数量较多,和/或发送BSR的所述第一UE的数据量较多,和/或所述BSR指示的缓存数据量较多,则基站向所述 第二UE发送调度的调度信息中包括的指示所述第二UE上报感知的SL资源位置的个数较多。如此,可以减少因调度SL资源较少而引起过高的调度等待时延,以及减少SL资源碰撞冲突的概率。
若与基站连接的UE数量较少,和/或发送BSR的所述第一UE的数据量较少,和/或所述BSR指示的缓存数据量较少,则基站向所述第二UE发送调度的调度信息中包括的指示所述第二UE上报感知的SL资源位置的个数较少。如此,可以降低当不需要过多SL资源而调用较多的SL资源信息、导致的占用过多的传输资源,从而减少第二UE上报空闲SL资源信息所述使用的资源开销。
例如,在一个时刻,若与所述基站连接UE数量为10个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的8个空闲SL资源位置的调度信息。在另一个时刻,若与所述基站连接UE的数量为5个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的4个空闲SL资源位置的调度信息。
又如,在一个时刻,若发送BSR的所述第一UE的数量为10个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的10个空闲SL资源位置的调度信息。在另一个时刻,若发送BSR的所述第一UE的数量为5个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的5个空闲SL资源位置的调度信息。
再如,在一个时刻,若所述BSR指示的缓存数据量为1G,所述基站向所述第二UE发送包括指示所述第二UE上报感知10个空闲SL资源位置的调度信息。在另一个时刻,若所述BSR指示的缓存数据为0.5G,所述基站向所述第二UE发送包括指示所述第二UE上报感知5个空闲SL资源位置的调度信息。
如此,在本公开实施例中,要求第二UE发送SL资源的数量,是根据 与所述基站连接的UE数量,和/或发送BSR的所述第一UE的数量,和/或所述BSR指示的缓存数据量,动态决定的;当前与所述基站连接的UE数量、发送BSR的所述第一UE的数据量、及所述BSR指示的缓存数据量之中的任意一个或多个比较多的时候,基站可以要求第二UE发送对应数量的SL资源。
例如:若与所述基站连接UE数量为10个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的8个空闲SL资源位置的调度信息。再例如,若与所述基站连接UE的数量为5个,所述基站向所述第二UE发送包括指示所述第二UE上报感知的4个空闲S资源位置的调度信息。
如此,本公开实施例中可以基于与所述基站连接的UE的数量、发送BSR的第一UE的数量以及所述BSR指示缓存数量的其中至少之一,动态选择合适指示所述第二UE上报感知空闲SL资源位置的个数的调度信息进行SL资源的调度;从而能够在提高SL资源利用率的同时,还能进一步减少所述第一UE的等待延时等。
在一些实施例中,所述接收所述第二UE基于所述调度信息上报的直传链路SL资源感知信息,包括:
接收所述第二UE基于物理上行控制信道(Physical Uplink Control Channel,PUCCH)和/或物理上行共享信道上报的所述SL资源感知信息。
在本公开实施例中,可以通过物理上行控制信道或物理上行共享信道的其中至少之一传输SL资源感知信息,如此,提供了多种上传SL资源感知信息的方式,以及提高所述SL资源感知信息上传效率。
这里需要指出的是:以下一种信息处理方法的描述,是应用在第二UE的,与上述应用在基站的所述信息处理方法的描述是类似的。对于本公开中应用于第二UE的基于所述信息处理方法实施例中未披露的技术细节,请参照本公开应用在基站的所述信息处理方法实施例的描述,此处不做详细 阐述说明。
如图6所示,本公开实施例提供一种信息处理方法,所述方法包括:
步骤S21,接收基站发送的调度信息,其中,所述调度信息为根据第一UE发送给所述基站的缓存状态报告BSR确定的信息;
步骤S22,基于所述调度信息,向所述基站上报用于使所述基站为所述第一UE分配SL资源的SL资源感知信息。
这里,在实际应用中,所述第二UE还可以基于自身获取的所述SL感知信息,获取空闲SL资源;并基于所述空闲SL资源向其它UE发送信息。
