Description

确定直连链路资源的方法、装置、用户设备及基站 技术领域
本公开涉及通信技术领域,尤其涉及一种确定直连链路资源的方法、装置、用户设备及基站。
背景技术
随着无线通信技术的发展,移动通信网络逐渐向5G NR(New Radio,新空口)系统演进。在5G NR系统中,也引入了Sidelink(直连链路)技术,即用户设备之间利用无线资源直接通信。与4G LTE(Long Term Evolution,长期演进)系统中的Sidelink技术类似,上述NR系统的Sidelink技术可以应用于V2X(Vehicle-to-Everything,车联网)等应用场景中。
在LTE系统中,UE利用Sidelink技术与其它UE通信时,可以采用网络动态调度方式,或者,从网络广播的资源池中自主选择的方式确定无线传输资源。在LTE系统中,UE只能选择一种资源分配方式确定sidelink传输资源。其中,网络广播的方式不需要空闲态UE进入连接态,可以节约空口的信令开销,但是网络需要为广播中的sidelink资源池预留资源,资源利用率较低。网络动态调度的方式可以根据实际发生的sidelink业务需求分配资源,资源利用率较高,但是要求空闲态UE进入连接态,增加了信令开销。

具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。

应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如, 在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开涉及的执行主体包括:5G NR系统中支持Sidelink(直连链路)技术的用户设备(User Equipment,UE)和基站,其中,用户设备可以是用户终端、用户节点、移动终端、平板电脑、车载设备等。基站可以是设置有大规模天线阵列的基站、子基站等。在具体实现过程中,基站和用户设备各自独立,同时又相互联系,共同实现本公开提供的技术方案。
本公开的应用场景可以是V2X(Vehicle to Everything,车联网)。其中,V2X可以包括:V2V车与车之间的通信、表示汽车与路边单元之间的通信V2I(Vehicle to Infrastructure,车辆对路边单元)、表示汽车与司机的移动终端之间的通信V2N(Vehicle to Nomadic Device,车辆对移动设备)、表示汽车与行人的移动终端之间的通信V2P(Vehicle to Pedestrain,车辆对行人)等通信方式,参见图1根据一示例性实施例所示的应用场景示意图。在上述应用场景中,上述支持Sidelink(直连链路)技术的UE可以是车载设备、路边基础设施装置、行人的移动终端等设备。在Sidelink技术中,UE可以利用系统配置的Sidelink传输资源,向其它UE传输信息。
上述用户设备在准备利用Sidelink(直连链路)技术向周边的UE发送信息之前,需要首先确定Sidelink资源。
基于此,本公开提供了一种确定直连链路资源的方法,应用于5G新空口NR系统的用户设备中。
参见图2根据一示例性实施例示出的一种确定直连链路资源的方法流程图,所述方法可以包括以下步骤:
在步骤11中,确定sidelink资源配置信息,所述sidelink资源配置信息用于指示用户设备根据待传输sidelink数据的服务质量QoS信息确定目标sidelink资源;
本公开中的sidelink资源配置信息,主要用于指示UE根据待传输sidelink数据的服务质量QoS信息、采用何种方式确定目标sidelink资源。
其中,上述待传输sidelink数据包括:待发送或待接收的sidelink数据。待传输sidelink数据的服务质量QoS信息表示待传输sidelink数据对传输可靠性、传输时延、传输速率、传输距离等传输性能参数的要求。
上述目标sidelink资源是指用于承载待传输sidelink数据传输的无线资源。
以用户设备是UE1为例,本公开中,UE1可以采用以下至少两种方式确定 sidelink资源配置信息;
方式一,UE1中已经存储有当前小区广播的sidelink资源配置信息,UE1直接根据已存储信息确定sidelink资源配置信息。
方式二,若UE1中没有预存当前小区的sidelink资源配置信息,UE1可以接收小区广播的sidelink资源配置信息。
与LTE sidelink技术类似,在5G NR中,支持sidelink技术的基站可以按照协议约定周期性向服务小区内的UE广播sidelink资源配置信息。
其中,上述sidelink资源配置信息可以携带在预设系统信息中。示例性的,若5G NR sidelink技术仍沿用LTE sidelink协议,可以由系统信息SIB18、19、21、26,携带上述sidelink资源配置信息,广播至小区内的UE。当前小区内处于空闲态(IDLE)的UE接收到上述系统信息后,可以从中解析出上述sidelink资源配置信息。
在步骤12中,根据待发送sidelink数据的QoS信息和所述sidelink资源配置信息,确定目标资源确定方式;
本公开中,在UE确定待发送sidelink数据之后,可以根据相关技术获知该待发送sidelink数据的QoS信息;然后,根据待发送sidelink数据的QoS信息和所述sidelink资源配置信息,确定目标资源确定方式。
其中,上述QoS信息可以包括:业务数据优先级指示信息,或者,信道质量指示信息。
在一实施例中,上述业务数据优先级指示信息可以是直连数据包优先级指示信息(Prose Per Packet Priority,PPPP)。上述信道质量指示信息可以是5G NR系统中按照预置规则量化表示信道质量的5QI信息。示例性的,上述5QI信息与LTE系统中的CQI类似,可以按照系统约定、量化表示为预设数量的5QI等级。
上述目标资源确定方式用于指示UE采用什么方式确定上述目标sidelink资源。
本公开中,系统可以约定在NR sidelink技术中,UE也可以采用以下两种sidelink资源确定方式来确定目标sidelink资源:
第一种资源确定方式,UE从系统预先配置的资源池中选择目标sidelink资源;
第二种资源确定方式,连接态UE请求基站为其动态配置目标sidelink资源。
本公开中,UE可以按照预置策略从上述资源确定方式中确定一种方式,作为目标资源确定方式。
根据sidelink资源配置信息的不同,UE可以采用以下至少一种方式实施上述步骤12:
第一种方式,所述sidelink资源配置信息包括:预设资源池与第一预设QoS信息的对应关系;
与LTE sidelink技术类似,在NR sidelink技术中,系统也可以使用资源池对5G NR系统中的sidelink通信所使用的时频资源进行管理。其中,一个资源池是在给定系统带宽上的周期性的时间频率资源的集合。
本公开中,系统可以仅约定当UE的待发送sidelink数据的QoS信息满足预设QoS信息时,允许空闲态UE从预设资源池中选择目标sidelink资源,从而避免系统因配置过多的资源池而占用过多资源、导致资源利用低。
示例性的,系统可以约定:当待发送sidelink数据的业务优先级较高时,空闲态UE可以从预设资源池中选择目标sidelink资源,以传输所述待发送sidelink数据。
参见图3根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,上述步骤12可以包括:
在步骤1211中,确定所述第一预设QoS信息是否包括所述待发送sidelink数据的QoS信息;
本公开中,UE1在确定所述待发送sidelink数据的QoS信息之后,可以确定上述第一预设QoS信息是否包括所述待发送sidelink数据的QoS信息;若包括,执行下述步骤1212。
若不包括,一种情况下,说明UE1无法根据当前基站的资源配置信息确定sidelink资源,UE1可以放弃sidelink传输或者切换至其它小区确定目标sidelink资源;在另一种情况下,UE1可以根据系统约定信息,进入连接态、请求基站为其动态调度sidelink资源,后续将结合具体实施例进行详细描述。
在步骤1212中,若所述第一预设QoS信息包括所述待发送sidelink数据的QoS信息,将第一种资源确定方式确定为所述目标资源确定方式,所述第一种资源确定方式为:从所述预设资源池中确定所述目标资源。
本公开实施例中,系统可以约定基站可以为不同应用场景配置不同的预设资源池,例如,针对V2V、V2I、V2N、V2P配置不同的预设资源池。
对于同一个应用场景,基站可以采用一对一、一对多、多对一、多对多等方式,配置预设资源池与预设QOS信息之间的对应关系。
以上述一对一方式为例,假设针对V2N应用场景,系统约定有两个预设资源池A和B,分别对应第一预设QoS信息:QoS a、QoS b;则上述sidelink资源配置信息可以如表一所示:
表一
资源池标识 第一预设QoS信息
资源池A QoS a
资源池B QoS b
假设处于空闲态的UE1,确定当前待发送sidelink数据的QoS信息为QoS a,则UE1可以确定从目标预设资源池即预设资源池A中选择目标sidelink资源;即将第一种资源确定方式确定为目标资源确定方式。
参见图4根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,在图3所示实施例的基础上,上述步骤12还可以包括:
在步骤1213中,若所述第一预设QoS信息中不包括所述待发送sidelink数据的QoS信息,将所述第二种资源确定方式确定为所述目标资源确定方式,所述第二种资源确定方式为:请求网络动态调度sidelink资源。
在本公开实施例中,若UE确定所述第一预设QoS信息中不包括所述待发送sidelink数据的QoS信息,一种情况下,UE可以根据系统约定信息,采用请求网络动态调度方式即上述第二种资源确定方式获取目标sidelink资源。
在本公开另一实施例中,基站广播的sidelink资源配置信息包括:上述预设资源池与第一预设QoS信息的对应关系,还可以包括:第一预设指示信息,该第一预设指示信息用于告知UE当所述第一预设QoS信息中不包括所述待发送sidelink数据的QoS信息时,采用上述第二种资源确定方式请求基站为其动态调度sidelink资源。
其中,上述第一预设指示信息可以用预设系统信息中的预设bit值表示,比如,当系统约定利用SIB18承载上述sidelink资源配置信息时,系统还可以约定利用SIB18中、序号为N的bit承载上述第一预设指示信息,当该序号为N的bit被置为1时,表示承载有上述第一预设指示信息,即指示基站支持下述能力:当所述第一预设QoS信息中不包括所述待发送sidelink数据的QoS信息时,UE可以采用上述第二种资源确定方式请求基站为其动态调度sidelink资源。
反之,当上述序号为N的bit被置为0时,表示基站广播的所述sidelink资源配置信息中不包括上述第一预设指示信息。相应的,表示基站不支持上述能力,此时,UE可以按照其他方式如切换至其它基站服务的小区获取目标sidelink资源。
相应的,上述步骤1213具体包括:若所述第一预设QoS信息中不包括所述待发送sidelink数据的QoS信息,按照所述第一预设指示信息将所述第二种资源确定方式确定为所述目标资源确定方式。
第二种方式,所述sidelink资源配置信息包括:第二预设QoS信息与第二种资源确定方式的对应关系,所述第二种资源确定方式为:请求网络动态调度sidelink资源。
参见图5根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,上述步骤12可以包括:
在步骤1221中,确定所述第二预设QoS信息是否包括所述待发送sidelink数据的QoS信息;
本公开实施例中,基站广播的所述sidelink资源配置信息可以包括:第二预设QoS信息与第二种资源确定方式的对应关系。
在本公开一实施例中,上述sidelink资源配置信息可以具体表示为一个预设sidelink QoS列表。
仍如上示例,在UE1确定待发送sidelink数据的QoS信息之后,或者,在UE1确定上述第一预设QoS信息不包括所述待发送sidelink数据的QoS信息的情况下,可以遍历上述预设sidelink QoS列表,判断上述第二预设QoS信息中是否包括待发送sidelink数据的QoS信息;若包括,执行下述步骤1222;若不包括,可以按照相关约定采用其它方式确定目标sidelink资源或者放弃在当前小区内进行sidelink传输。
在步骤1222中,若所述第二预设QoS信息包括所述待发送sidelink数据的QoS信息,将所述第二种资源确定方式确定为所述目标资源确定方式。
示例性的,假设所述sidelink资源配置信息所指示的内容可以如表二所示:
表二
Figure PCTCN2019071213-appb-000001
假设UE1的待发送sidelink数据的QoS信息为QoS c;查询上述表二可知,UE1可以将第二种资源确定方式即请求网络动态调度方式确定为目标资源确定方式。
本公开实施例中,基站可以通过所述sidelink资源配置信息告知小区内的UE符合网络动态调度资源的条件,以使UE根据待发送sidelink数据的QoS信息确定满足上述预设条件时,进入连接态,在与基站建立通信连接的情况下,请求基站为其动态分配sidelink资源。
第三种方式,所述sidelink资源配置信息可以包括:第三预设QoS信息与第二种资源确定方式、预设无线接入类型之间的对应关系;如上所述,第二种资源确定方 式为:请求网络动态调度sidelink资源。
其中,上述第三预设QoS信息可以与上述第二预设QoS信息相同,也可以不同。
参见图6根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,上述步骤12可以包括:
在步骤1231中,确定所述第三预设QoS信息是否包括所述待发送sidelink数据的QoS信息;
与上述步骤1221类似,在UE1确定待发送sidelink数据的QoS信息之后,或者,在UE1确定上述第一预设QoS信息不包括所述待发送sidelink数据的QoS信息的情况下,UE1可以判断上述第三预设QoS信息中是否包括待发送sidelink数据的QoS信息;
若包括,执行下述步骤1232;若不包括,可以按照相关约定采用其它方式确定目标sidelink资源或者放弃在当前小区内进行sidelink传输。
在步骤1232中,若所述第三预设QoS信息包括所述待发送sidelink数据的QoS信息,确定所述用户设备是否支持所述待发送sidelink数据的QoS信息对应的目标无线接入技术类型;
其中,上述目标无线接入技术类型可以包括:NR sidelink接入技术,和/或,LTE sidelink接入技术。
仍以UE1为例,若UE1确定所述第三预设QoS信息中包括待发送sidelink数据的QoS信息后,还需要进一步判断其自身所支持的sidelink无线接入技术类型是否满足系统要求的无线接入技术类型,若满足,执行下述步骤1233;否则,可以按照相关约定采用其它方式确定目标sidelink资源,或者,放弃在当前小区内进行sidelink传输。
在步骤1233中,若所述用户设备支持所述目标无线接入技术类型,将所述第二种资源确定方式确定为所述目标资源确定方式。
本公开实施例中,对于UE1而言,当其确定的待发送sidelink数据的QoS信息和所支持的sidelink无线接入技术类型同时满足所述sidelink资源配置信息的要求时,可以将上述第二种资源确定方式确定为目标资源确定方式。
示例性的,假设所述sidelink资源配置信息所指示的内容可以如表三所示:
表三
Figure PCTCN2019071213-appb-000002
Figure PCTCN2019071213-appb-000003
假设UE1的待发送sidelink数据的QoS信息为QoS e;根据上述表三,UE1需要进一步判断所述待发送sidelink数据要求的sidelink无线接入技术是否为QoS e对应的目标无线接入技术类型即NR sidelink接入技术;若是,可以将第二种资源确定方式确定为目标资源确定方式。
本公开一实施例中,用户设备的APP层在生成上述待发送sidelink数据的数据包时可以指示上述待发送sidelink数据所需要的sidelink无线接入技术类型。
本公开实施例中,上述sidelink无线接入技术类型可以是LTE sidelink接入技术,也可以是NR sidelink接入技术,或者,两者均适用。
也就是说,UE1的物理层获得的待发送sidelink数据包中携带有sidelink无线接入技术指示信息,基于该指示信息,UE1可以确定上述待发送sidelink数据需要采用哪种sidelink无线接入技术。
本公开实施例中,基站不仅约定了可以采用第二种资源确定方式的sidelink数据的QoS信息,还进一步约定了sidelink无线接入技术类型,使得UE在确定待发送sidelink数据的QoS信息属于所述第三预设QoS信息并且所支持的sidelink无线接入技术类型也满足系统要求时,将上述第二种资源确定方式确定为目标资源确定方式。
在步骤13中,利用所述目标资源确定方式确定承载所述待发送sidelink数据传输的目标资源。
对应目标资源确定方式的不同,上述步骤13也可以包括两种情况:
情况一,所述用户设备确定的目标资源确定方式为上述第一种资源确定方式
相应的,步骤13可以包括:从所述待发送sidelink数据的QoS信息对应的目标预设资源池中确定所述目标资源。
如上述表一所示,当UE1的待发送sidelink数据的QoS信息为QoS a时,UE1可以从目标预设资源池A配置的资源中按照相关技术选择目标资源。
情况二,所述用户设备确定的目标资源确定方式为上述第二种资源确定方式
参见图7根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,上述步骤13可以包括:
在步骤131中,确定所述用户设备的当前连接状态;
UE在一个小区内的网络连接状态至少可以包括:空闲态(IDLE)和连接态(CONNECTED);UE只有在连接态下,才可以通过物理信道向基站发送数据。
在步骤132中,若所述用户设备当前处于空闲态,向所述基站请求建立网络连接;
在步骤133中,若所述用户设备当前处于连接态,向所述基站发送sidelink资源请求信息;
其中,所述sidelink资源请求信息用于请求基站为所述用户设备动态调度sidelink资源。
如上述示例,若UE1当前处于空闲态,首先需要向基站请求建立网络连接,比如向基站发送随机接入请求,在基站响应上述随机接入请求并允许接入小区网络的情况下,即进入连接态后,UE1向基站发送所述sidelink资源请求信息,请求基站为其调度sidelink资源。
本公开实施例提供一种确定直连链路资源的方法,用户设备可以根据待发送sidelink数据的服务质量信息(QoS信息)匹配系统的sidelink资源配置信息,该sidelink资源配置信息指示了sidelink数据的QoS信息与预设资源确定方式的对应关系;确定适合当前待发送sidelink数据的目标资源确定方式,从而利用目标资源确定方式确定用于承载待发送sidelink数据传输的目标资源。采用上述sidelink资源确定方式可以根据系统规划,确定合适的资源确定方式获取目标资源,从而使系统合理平衡资源利用率和信令开销之间的关系,提高系统资源的有效利用率并且减少系统信令开销。
参见图8根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,在上述步骤11之后,所述方法还可以包括:
在步骤10中,向所述基站发送sidelink辅助信息,以使所述基站参考所述sidelink辅助信息为所述用户设备调度sidelink资源。
在本公开一实施例中,UE1在接收到基站广播的sidelink资源配置信息后,还可以向基站发送自身的sidelink辅助信息;其中,上述UE1的sidelink辅助信息用于告知基站UE1适用sidelink技术的相关信息,如目的端标识、当前是否需要进行sidelink传输等信息。
在本公开一实施例中,UE1可以通过sidelink UE Information消息向基站发送上述sidelink辅助信息。
相应的,基站获取到UE1的sidelink辅助信息之后,可以确定是否能为UE1调度sidelink资源,以及在可以为UE1调度sidelink资源的情况下,确定当前是否需要为UE1配置sidelink资源等信息,从而提高基站为UE动态调度sidelink资源的准确性,进而提高系统资源的有效利用率。
相应的,本公开还提供了一种确定直连链路资源的方法,应用于5G新空口NR系统的基站中。
参见图9根据一示例性实施例示出的一种确定直连链路资源的方法流程图,所述方法可以包括:
在步骤21中,确定直连链路sidelink资源配置信息,所述sidelink资源配置信息用于指示用户设备根据待传输sidelink数据的服务质量QoS信息确定目标sidelink资源;
如上所述,本公开中,基站可以针对不同的应用场景确定不同的sidelink资源配置信息。针对同一应用场景如V2V场景,基站可以配置预设资源池与预设QoS信息之间的对应关系,和/或,预设QoS信息与上述第二种资源确定方式之间的对应关系;根据上述预设QoS信息与预设资源确定方式的对应关系,生成上述sidelink资源配置信息。
在步骤22中,将所述sidelink资源配置信息广播至服务小区的用户设备,以使所述用户设备根据待发送sidelink数据的QoS信息和所述sidelink资源配置信息,确定用于承载所述待发送sidelink数据传输的目标资源。
本公开中,所述sidelink资源配置信息可以包括以下至少一项:
预设资源池与第一预设QoS信息的对应关系;
第二预设QoS信息与第二种资源确定方式的对应关系,所述第二种资源确定方式为:请求网络动态调度sidelink资源;
第三预设QoS信息与第二种资源确定方式、预设无线接入类型之间的对应关系。
相应的,UE在接收到上述sidelink资源配置信息后,可以按照上述图3~图7所示的至少一种实施例确定用于承载所述待发送sidelink数据传输的目标资源。
参见图10根据一示例性实施例示出的另一种确定直连链路资源的方法流程图,所述方法还可以包括:
在步骤23中,接收所述用户设备发送的sidelink辅助信息;
与上述步骤10对应,仍以UE1为例,基站可以接收UE1发送的sidelink辅助信息,该UE1的sidelink辅助信息用于告知基站UE1使用sidelink技术的相关信息,比如,目的端标识、当前是否需要进行sidelink传输等信息。
在步骤24中,参考所述sidelink辅助信息确定针对所述用户设备的资源调度方式。
基站获取到UE1的sidelink辅助信息之后,可以确定自身是否能为UE1调度sidelink资源,以及在确定基站可以为UE1调度sidelink资源的情况下,确定当前是否需要为UE1配置sidelink资源等信息。
例如,当前基站根据UE1的sidelink辅助信息确定自身没有能力为UE1动态调度sidelink资源时,可以对UE1进行移动性管理,指示UE1切换至其它可以为UE1动态调度sidelink资源的目标基站所服务小区。
或者,若基站根据UE1的sidelink辅助信息确定UE1当前不需要进行sidelink传输,则基站可以将UE1作为一般UE进行资源调度,暂时不为UE1配置sidelink资源,当UE1请求基站为其调度sidelink资源时,再为UE1配置sidelink资源,从而避免基站在UE1不需要sidelink传输时还使用信令告知sidelink资源配置信息,减少系统信令开销。
