具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚,下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
在车联网系统中,车联网终端通过车用无线通信技术(vehicle-to-everything,V2X)实现车与X(车、人、交通路侧基础设施和网络)智能信息的交互。V2X通信的交互模式包括:车辆与车辆(vehicle to vehicle,V2V)之间、车辆与路边基础设施(vehicle to infrastructure,V2I)之间、车辆与行人(vehicle to pedestrian,V2P)之间、车辆与网络(vehicle to network,V2N)之间的通信。示例性的,路边基础设施可以是路边单元(road side unit,RSU)。
图1为V2X通信的架构示意图。如图1所示,V2X通信包括V2V通信、V2P通信、V2I通信和V2N通信,V2X通信过程中,V2X业务通过侧行链路(sidelink)或者Uu口进行传输。
在实际应用中,V2X借助与人、车、路、云平台之间的全方位连接和高效信息交互,实现信息服务、交通安全、交通效率等典型应用场景。车联网终端通过V2I和V2N通信可以获取各种信息服务,包括交通信号灯信息,附近区域车辆信息,车辆导航,紧急救援,信息娱乐服务等。通过V2V和V2P通信可以实时获取周围车辆的车速、位置、行车情况及行人活动等信息,并通过智能算法实现碰撞预警功能,避免交通事故。通过V2I通信可以实现车速引导等功能,提高交通效率。
随着技术的不断发展,目前引入新无线(new radio,NR)通信系统,NR系统中V2X称之为NR-V2X。在NR-V2X系统中,需要支持自动驾驶,因此,对车载终端之间数据交互提出了更高的要求,如更高的吞吐量、更低的时延、更高的可靠性、更大的覆盖范围、更灵活的资源分配等。
在NR-V2X系统中,通过侧行链路进行通信称之为V2X sidelink通信模式。该种通信模式下,终端设备可以工作在有网络覆盖的场景,或者没有网络覆盖的场景。
在有网络覆盖的场景中,V2X sidelink通信模式进一步的划分为集中调度传输模式和分布式传输模式。
在集中调度传输模式下,终端设备在侧行链路传输V2X业务的传输资源是由网络设备分配的,在NR-V2X系统中称为模式1,也称为mode1;在分布式传输模式下,网络设备配置V2X sidelink资源池,终端设备每次传输V2X业务时,在网络配置的资源池中获取传输资源,无需网络设备调度,该模式在NR-V2X系统中称为模式2,也称为mode2。详见图2和图3所示示意图的记载。
图2是模式1所适用的系统架构示意图。图3是模式2所适用的系统架构示意图。参照图2和图3所示,第一终端设备和第二终端设备是具备V2X通信能力的终端设备,用于执行V2X通信,第一终端设备与第二终端设备之间通过无线通信接口进行V2X通信,第一终端设备与网络设备,或者,第二终端设备与网络设备之间通过无线通信接口进行通信。为清楚起见,将第一终端设备和第二终端设备之间的无线通信接口称之为第一空口,该第一空口例如为PC5口,第一终端设备和网络设备之间或第二终端设备与网络设备之间的无线通信接口称之为第二空口,该第二空口例如为Uu口。
参照图2所示,作为一种示例,第一终端设备与第二终端设备的传输资源是由网络设备分配,第一终端设备与第二终端设备根据网络设备分配的资源在侧行链路上进行数据的发送;网络设备可以为第一终端设备与第二终端设备分配单次传输的资源,也可以为第一终端设备与第二终端设备分配半静态传输的资源,此处不再赘述。
参照图3所示,作为另一种示例,第一终端设备可以在资源池中选取一个资源向第二终端设备传输数据。具体的,第一终端设备可以通过侦听的方式在资源池中选取传输资源,或者通过随机选取的方式在资源池中选取传输资源,并在选择的传输资源向第二终端设备传输数据,关于第一终端设备选取传输资源的方式,其可以根据实际情况确定,此处不再赘述。
在没有网络覆盖的场景中,终端设备采用上述的模式2进行传输,这时,资源池是通过预配置的方式获取的。具体的传输方式同上述的模式2,这里不再赘述。
由上述分析可知,与传统空口(Uu口)上下行通信不同,V2X通信技术可以使用PC5口进行侧行通信,网络设备会给PC5口通信预先分配资源池,可理解,在本申请实施例中,资源池也可称为V2X资源池。可选的,该资源池中包括一系列频域资源以及时域资源。
相应的,上述还介绍了终端设备使用资源池中的资源进行数据传输的两种方式,分别是侦听方式和随机选取方式。其中,侦听方式即先听后选方式,发送端终端设备在发送业务数据之前,首先监听一段时间,从资源池中确定出合适的发送资源,然后再发送业务数据。随机选取方式,即,终端设备在发送业务数据时,从资源池中随机选择传输业务数据的发送资源。
现阶段,资源池包含的资源是网络设备配置的,终端设备可以按照上述预设规则(即上述侦听方式或随机选取方式)从网络配置的资源池中选择资源进行数据收发,可能会存在终端设备能耗大、监听效果差或资源利用不合理的问题。具体分析如下:
一方面,预设规则的有效性受网络设备参数控制,比如:网络可以配置终端在选择资源前需要监听的周期和次数,但是若监听的周期和次数配置不合理,会存在终端能耗大或感知效果差的问题,例如,在网络设备配置的监听周期太短或监听次数过多时,会存在发送端终端设备能耗大的问题,不利于终端节能,在网络设备配置的监听周期太长或监听次数过少时,会存在发送端终端设备侦听效果差的问题,即终端资源占用感知效果不一定有效。
另一方面,网络设备配置的资源池的有效性有待考验,例如,资源池中可能存在干扰较大,数据收发效果不好的资源,即若网络设备配置的资源池不合适,会存在资源利用率不合理的问题等。
针对上述问题,本申请的技术构思过程如下:本申请的发明人发现,资源池使用过程中存在的终端设备能耗大、监听效果差或资源利用不合理,均是由于缺乏终端设备反馈优化手段造成的,因而,可以提出一种资源选择机制的优化控制方法,以优化资源池配置和/或资源占用感知过程相关的控制参数,具体的,若终端设备在使用资源池中的资源后,及时上报与资源池使用相关的记录数据,以便网络设备基于上报的记录数据调整资源选择配置参数和/或资源池配置信息,进而解决了资源池使用过程中存在的上述问题。
基于上述技术构思过程,本申请的实施例提供了一种选择资源的控制方法,终端设备使用网络设备配置的资源池中的子资源进行数据传输时,可以记录下使用资源池的相关信息,进而在后续可以获取到资源池使用相关的记录数据,并通过第一消息将资源池使用相关的记录数据上报给网络设备,相应的,网络设备接收到该第一消息后,便可以根据该第一消息中至少包括的资源池使用相关的记录数据调整资源池配置信息和/或调整为终端设备配置的资源选择配置参数,从而提高终端设备使用资源池中资源时的利用率,解决现有资源选择过程中存在的终端设备能耗大、监听效果差或资源池的资源利用不合理的问题。
可以理解的是,本申请实施例提供的选择资源的控制方法可用于车联网系统中,也可以用于任意的D2D系统或侧行传输系统中,还可以应用于第三代移动通信(the 3rd generation mobile communication,3G)、长期演进(long term evolution,LTE)系统,第四代移动通信(the 4th generation mobile communication,4G)系统、先进的长期演进系统 (advanced long term evolution,LTE-A)、第三代合作伙伴计划(the 3rd generation partnership project,3GPP)相关的蜂窝系统、第五代移动通信(the 5th generation mobile communication,5G)系统以及后续演进的通信系统。本申请实施例不对其进行限定。
本申请实施例中涉及的网络设备,可以是普通的基站(如NodeB或eNB或者gNB)、新无线控制器(new radio controller,NR controller)、集中式网元(centralized unit)、新无线基站、射频拉远模块、微基站、中继(relay)、分布式网元(distributed unit)、接收点(transmission reception point,TRP)、传输点(transmission point,TP)或者任何其它设备,但本申请实施例不限于此。
本申请实施例中涉及的终端设备是具备侧行通信能力的终端设备,也是一种向用户提供语音和/或数据连通性的设备,例如,具有无线连接功能的手持式设备、车载设备、路边单元等。常见的终端设备包括:手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device,MID)、可穿戴设备,例如智能手表、智能手环、计步器等。可理解,本申请实施例并不对终端设备的具体实现进行限定。
下面,通过具体实施例对本申请的技术方案进行详细说明。需要说明的是,下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。
图4为本申请提供的资源选择的控制方法实施例一的流程示意图。该方法以终端设备和网络设备之间的信息交互进行解释说明。如图4所示,该资源选择的控制方法可以包括如下步骤:
S400、终端设备向网络设备发送第一消息,该第一消息至少包括:资源池使用相关的记录数据。
可选的,在本申请的实施例中,终端设备向网络设备发送第一消息之前,可以获取资源池使用相关的记录数据,本实施例不作限定。
在V2X的场景中,终端设备之间使用PC5口进行侧行通信时,发送端终端设备可以首先从网络设备预先配置的资源池中选择传输资源,然后在该传输资源上向接收端终端设备传输信息。
可选的,终端设备每次从资源池中选择传输资源和/或使用传输资源的过程中,可以记录和/或收集每次使用资源池的相关情况并存储,得到资源池使用相关的记录数据。
可选的,终端设备可以周期性或实时性获取资源池使用相关的记录数据,并将其反馈至网络设备,以便网络设备可以及时获知该终端设备使用资源池的相关信息。
可理解,在本申请的实施例中,资源池使用相关的记录数据可以是该终端设备在预设时间段使用资源池的所有记录数据,也可以是单次使用资源池的记录数据,此处不对其进行限定。
可选的,终端设备获取或确定出资源池使用相关的记录数据后,可以通过第一消息的形式将资源池使用相关的记录数据发送给网络设备。
可理解,第一消息中不局限于包括资源池使用相关的记录数据,其还可以包括其他的信息,例如,终端设备的能力信息、指示信息等,此处不作赘述。
示例性的,在本申请的实施例中,上述记录数据(即,资源池使用相关的数据记录)包括如下至少一种:
第一项:终端设备使用的资源池感知周期;
第二项:终端设备使用的资源池感知重复次数;
可理解,网络设备预配置的资源池中的资源为公共资源,为了避免使用资源冲突,终端设备在发起自身业务之前需要感知或侦听资源池中各子资源被占用的情况,且终端设备的感知过程受网络设备配置的参数控制。
可选的,网络设备配置的参数至少包括资源池感知周期P,即终端设备在使用资源池 中的子资源之前,每次感知或侦听资源池中各个子资源是否被占用的时长。
可选的,网络设备配置的参数中还可以包括资源池感知重复次数K,通过资源池感知重复次数K指示终端设备在使用资源池中的子资源之前,感知或侦听资源池中各个子资源是否被占用的次数。
可选的,在网络设备配置的参数中不包括资源池感知重复次数K时,即不配置K时,默认K等于1,每轮的资源池感知过程为1次;而在配置K时,每轮的资源池感知过程需要重复K次。可理解,若配置的K=0,则终端设备可以直接在从资源池中选定的资源上发送数据,无需进行资源感知。因而,在本实施例中,K为自然数。
可理解,资源池资源也可以表述为资源池中的子资源或者资源池中的资源,本申请实施例并其对上述表述进行限定。
示例性的,图5为终端设备进行资源占用感知过程的示意图。可选的,以K等于2,时刻N为数据发送时刻为例进行说明。如图5所示,在数据发送时刻N之前的两个时间窗内(即:包含时刻(N-2P)的资源感知窗口和包含时刻(N-P)的资源感知窗口),终端设备需要感知资源池包含的各子资源被占用的情况,从而,终端设备根据在该两个时间窗内的资源池感知结果,可以在数据发送时刻N时,优先考虑使用未被占用的子资源或者干扰较小的子资源发送数据,进而尽可能保证数据传输的可靠性。
其中,K表示终端设备在数据发送时刻N之前需要执行资源感知过程的次数,每一次资源感知过程对应一个资源感知时间窗,如图5所示,资源感知时间窗包括时刻(N-k*P),其中,k取值范围为{0,1,2,……,K},P为资源池感知周期。
第三项:终端设备的资源池感知结果与实际资源占用情况不符的次数占终端设备的资源池感知总次数的比例;
可选的,终端设备的资源池感知结果与实际资源占用情况不符可以解释为:经过资源感知过程后,终端设备选择了未被占用或干扰较小的某一子资源,但实际发送数据时发现该子资源已经被占用或者该子资源上的干扰相对较大,这时导致了数据传输效果差。
可选的,出现终端设备的资源池感知结果与实际资源占用情况不符的原因可能是因为资源池感知周期P和资源池感知重复次数K配置不合理,毕竟终端设备的资源池感知过程和实际的数据发送时刻存在时间间隔,在该时间间隔内,资源池中的资源使用情况可能发生变化,因而会出现资源池感知结果与实际资源占用情况不符的情况。
可选的,通常情况下,资源池感知重复次数K一定程度决定了终端设备进行资源占用的感知准确度。具体的,资源池感知重复次数K越大,感知准确度越高,资源池感知重复次数K越小,感知准确度越低。
在本申请的实施例中,上述第一项和第二项参数可以通过该第三项参数进行优化,从而尽可能降低终端设备的误感率,同时减少资源感知频次或者延长感知周期。
第四项:预配置的资源池全量信息;
可选的,若网络设备预配置了资源池全量信息,则终端设备在进行资源感知过程中,可以记录网络设备预配置的上述资源池全量信息。
第五项:平均被占用率高于第一阈值的资源池子资源对应的配置信息;
可选的,在本申请的实施例中,平均被占用率高于第一阈值的资源池子资源对应的配置信息也可以解释为资源池中的第一子资源对应的配置信息,其中,该第一子资源的平均被占用率高于第一阈值。
示例性的,假设终端设备进行了10轮资源感知过程(图5表示一轮资源感知过程),终端设备感知到资源池中某一子资源1(第一子资源)被占用的次数为7次,则子资源1的平均被占用率为0.7(即:7除以10),假设第一阈值为0.5,那么终端设备需要记录子资源1对应的配置信息。
第六项:平均被占用率低于第二阈值的资源池子资源对应的配置信息;
可选的,在本申请的实施例中,平均被占用率低于第二阈值的资源池子资源对应的配置信息可以解释为资源池中的第二子资源对应的配置信息,其中,该第二子资源的平均被占用率低于第二阈值。
示例性的,假设终端设备进行了10轮资源感知过程(图5表示一轮资源感知过程),终端设备感知到资源池中的某一子资源2(即,第二子资源)被占用的次数为2次,则子资源2的平均被占用率为0.2(即:2除以10),假设第二阈值为0.4,那么终端设备需要记录子资源2对应的配置信息。
第七项:平均被占用率高于第三阈值的资源池子资源占资源池总资源的比例;
可选的,在资源池中,满足第一条件的子资源数量占资源池中总子资源数量的比例,其中,第一条件为子资源的平均被占用率高于第三阈值。
示例性的,假设终端设备在一段时间进行资源感知过程时,确定资源池共包含8个子资源,其中5个子资源的平均占用率高于第三阈值,那么平均被占用率高于第三阈值的资源池子资源占整个资源池资源的比例为5/8,即:0.625。
第八项:平均被占用率低于第四阈值的资源池子资源占资源池总资源的比例;
可选的,在资源池中,满足第二条件的子资源数量占资源池中总子资源数量的比例,其中,第二条件为子资源的平均被占用率低于第四阈值。
示例性的,假设终端设备在一段时间进行资源感知过程时,确定资源池包含8个子资源,其中3个子资源的平均占用率低于第四阈值,那么平均被占用率低于第四阈值的资源池子资源占整个资源池资源的比例为3/8,即:0.375。
可理解,本申请实施例并不限定上述第一阈值、第二阈值、第三阈值和第四阈值的具体取值以及各自的大小关系,其可以根据实际场景确定,此处不作赘述。
第九项:资源池中的资源平均被占用率;
可选的,该第九项也可以解释为:在一段时间内,资源池中被占用的子资源总数量与资源池中总子资源数量的比例的平均值。
可选的,在实际应用中,上述第四项(预配置的资源池全量信息)可以通过第五项到第九项进行优化,其中第五项和第六项可以用于精准识别哪些子资源需要保留,哪些需要替换,从而保证资源池中的资源具有较好的数据传输效果;第七项、第八项和第九项可以用于判断资源池的整体使用率,便于网络设备动态调整资源池大小,避免资源池使用率过高或者过低的现象出现。
第十项:终端设备是否支持资源池资源随机选择功能;
在实际应用中,有些终端设备由于业务类型或者能力等级原因,从资源池中选择资源进行数据传输之前,不需要提前感知资源占用情况,而是直接在资源池中随机选择传输资源进行发送数据。也即,支持资源池资源随机选择功能的终端设备不需要提前感知资源占用情况,而不支持资源池资源随机选择功能的终端设备需要提前感知资源占用情况。所以,终端设备在使用资源池中的资源时,还可以记录终端设备是否支持资源池资源随机选择功能。
第十一项:终端设备的优先级信息,该优先级信息用于判断是否采用资源池资源随机选择功能。
可选的,在实际应用中,不同的终端设备具有的优先级,因而,终端设备在使用资源池的资源时,可以基于该终端设备具有的优先级,确定其是否采用资源池随机选择功能,也即在发送数据之前是否需要进行资源感知过程。
示例性的,假设同时存在多个终端设备均需要使用资源池中的资源,这时可以根据该多个终端设备的优先级顺序确定哪些终端设备可以采用资源池随机选择功能,哪些终端设备需要进行资源感知过程。
例如,对于优先级高低不同的两个终端设备,假定优先级较高的终端设备可以采用资 源池资源随机选择功能,而优先级较低的终端设备不采用资源池资源随机选择功能,在使用资源池的资源之前,需要进行资源感知过程。
可选的,由于资源随机选择终端和资源感知选择终端的资源选择逻辑完全不同,上述第十项和第十一项用于告知网络设备终端类型信息,从而避免将需要进行资源感知的终端设备和不需要进行资源感知的终端设备(资源随机选择终端)上报的数据混在一起优化。
可选的,在本申请的实施例中,上述第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项通过如下任意一种方式配置:
预配置方式、默认配置方式、系统广播消息配置方式或专用信令配置方式。
对于预配置方式,具体的,网络设备可以为终端设备预配置上述第一阈值、第二阈值、第三阈值、第四阈值、优先级信息,以便终端设备在记录资源池使用相关的数据时,可以基于第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的任意一项生成上述记录数据中的对应数据项。
可选的,预配置方式对应的预配置信息可以是侧行带宽部分(bandwidth part,BWP)配置信息,该BWP配置信息中的指示信息用于指示第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项。
可选的,预配置方式对应的预配置信息也可以是资源池(Resource Pool,RP)配置信息,该RP配置信息中的指示信息用于指示第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项。
对于默认配置方式,协议中可以直接给出第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项的默认取值,默认取值方式不需要网络设备显性配置过程,默认取值也可以理解为常数取值。
对于系统广播消息配置方式,在本申请的实施例中,网络设备可以配置第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项,可以通过广播形式将其告知其服务小区内的各个终端设备。
对于专用信令配置方式,网络设备可以通过专用信令将该上述第一阈值、第二阈值、第三阈值、第四阈值、优先级信息中的至少一项配置给终端设备,终端设备在接收到上述配置参数后,可以将其进行存储并使用。
可选的,该专用信令可以是无线资源控制(radio resource control,RRC)信令、媒质接入控制的控制单元(MAC control element,MAC CE)、下行控制信息(downlink control information,DCI)中的任意一种。
可选的,在本申请的实施例中,在上述S400之后,网络设备可以对接收到的第一消息进行处理,例如,根据第一消息中包括的资源池使用相关的记录数据,调整资源选择配置参数和/或资源池配置信息。
可选的,在本申请的实施例中,网络设备可以接收终端设备发送的第一消息,通过对该第一消息进行解析,至少可以得到资源池使用相关的记录数据,进而可以根据该资源池使用相关的记录数据,通过调整该终端设备的感知参数,以降低资源感知的误感率,或者通过调整资源池中的子资源,以提高资源池中资源的数据传输效果,或者通过调整资源池的大小,以提高资源池中资源的合理利用。
本申请实施例提供的选择资源的控制方法,终端设备使用网络设备配置的资源池中的子资源进行数据传输时,可以记录下使用资源池的相关信息,进而在后续可以获取到资源池使用相关的记录数据,并通过第一消息将资源池使用相关的记录数据上报给网络设备,相应的,网络设备接收到该第一消息后,便可以根据该第一消息中至少包括的资源池使用相关的记录数据调整资源池配置信息和/或调整为终端设备配置的资源选择配置参数,从而提高终端设备使用资源池中资源时的利用率,解决现有资源选择过程中存在的终端设备能耗大、监听效果差或资源池的资源利用不合理的问题。
需要说明的是,网络设备获取终端设备上报的资源池使用相关的记录数据后可以针对单个终端设备进行配置参数优化;或者,待收集到足够数量的终端设备上报的资源池使用相关的记录数据后进行综合配置参数优化,本申请对此不做限定。
示例性的,在上述实施例的基础上,图6为本申请提供的资源选择的控制方法实施例二的流程示意图。如图6所示,在上述S400之前,可选的,该资源选择的控制方法还可以包括如下步骤:
S601、终端设备向网络设备发送第二消息,该第二消息包括:第一指示信息,该第一指示信息用于指示终端设备记录的资源池使用相关的记录数据可取。
可选的,在实际应用中,终端设备是否可以上报自身记录的资源池使用相关的记录数据需要与网络设备进行协商,此时,终端设备可以通过第二消息向网络设备上报第一指示信息,以告知网络设备终端设备侧存在未被网络设备提取的资源池使用相关的记录数据。
S602、网络设备向终端设备发送第二消息的响应消息,该响应消息包括:第二指示信息,该第二指示信息用于指示终端设备上报资源池使用相关的记录数据。
可选的,网络设备基于接收到的第二消息中的第一指示信息,确定终端设备中存在未被提取的资源池使用相关的记录数据,如果网络设备同意提取该终端设备存储的资源池使用相关的记录数据,则通过第二消息响应消息向该终端设备发送第二指示信息,以指示该终端设备上报存储的资源池使用相关的记录数据。
可理解,图6中的S601和S602步骤为可选步骤,在实际应用中不做限定。
示例性的,在上述实施例的基础上,图7为本申请提供的资源选择的控制方法实施例三的流程示意图。如图7所示,在上述S400之前,可选的,该资源选择的控制方法还可以包括如下步骤:
S701、终端设备向网络设备发送能力指示信息,该能力指示信息用于指示终端设备是否支持收集或者记录资源池使用相关的记录数据中的至少一项数据。
可选的,在实际应用中,有些终端设备由于业务类型或者能力等级原因,可能不支持收集或者记录资源池使用相关的记录数据的情况,因而,终端设备可以向网络设备上报能力指示信息,以指示其支持或者不支持收集或记录资源池使用相关的记录数据中的数据项。
相应的,网络设备通过接收该终端设备上报的能力指示信息,确定终端设备是否支持收集或者记录所述资源池使用相关的记录数据中的至少一项数据。
在本申请实施例的一种可能设计中,终端设备上报的能力指示信息的数量为一个,此时,这一个能力指示信息用于指示终端设备是否具备记录所述资源池使用相关的记录数据中任意数据项的能力。也就是说,第一消息包括的资源池使用相关的记录数据的全部数据项共用一个能力指示信息,只有终端设备支持该能力指示信息对应的能力,终端设备才能够记录上述资源池使用相关的记录数据中的任意数据项。
在本申请实施例的另一种可能设计中,终端设备上报的能力指示信息的数量为至少两个;此时,每个能力指示信息用于指示终端设备是否具备记录所述资源池使用相关的记录数据中单个数据项或一组数据项的能力。也就是说,第一消息包括的资源池使用相关的记录数据的一组或者全部数据项分别对应独立的能力指示信息,只有在对应数据项的能力指示信息指示允许前提下,终端设备才能记录对应的数据项。
作为一种示例,在本申请的实施例中,该方法还可以包括如下步骤:
S702、网络设备向终端设备发送配置消息,该配置消息包括:数据收集指示信息,该数据收集指示信息用于指示是否允许终端设备记录资源池使用相关的记录数据中的数据项。
示例性的,网络设备可以通过配置消息向终端设备发送数据收集指示信息,以指示是否允许终端设备收集资源池使用相关的记录数据中的数据项。
可选的,上述数据收集指示信息的取值用于指示允许或禁止;例如,假设数据收集指 示信息的取值为0或1,相应的,在数据收集指示信息的取值为1时,指示允许,即允许对应数据项的收集;在数据收集指示信息的取值为0时,指示禁止,即不允许对应数据项的收集。在另一种实现方式下,0或1含义可以对调,本申请对此不做限定。
作为一种示例,在数据收集指示信息的取值指示允许时,终端设备记录资源池使用相关的记录数据中的数据项;作为另一种示例,在数据收集指示信息的取值指示禁止时,终端设备不记录资源池使用相关的记录数据中的数据项。
在本申请实施例的一种可能设计中,数据收集指示信息的数量为一个,这一个数据收集指示信息用于指示记录数据中所有数据项的收集与否。也即,第一消息包括的资源池使用相关的记录数据中的全部数据项的收集与否共用一个数据收集指示信息来指示,即终端设备接收到一个数据收集指示信息时,若其取值表示允许时,表示允许终端设备收集资源池使用相关的记录数据中的所有数据项,若其取值表示禁止时,表示不允许终端设备收集资源池使用相关的记录数据中的任意数据项。
在本申请实施例的另一种可能设计中,数据收集指示信息的数量为至少两个;此时,每个数据收集指示信息用于指示记录数据中的单个数据项或一组数据项的收集与否。也即,第一消息包括的资源池使用相关的记录数据中的一组或单个数据项的收集与否分别有独立的数据收集指示信息来指示,即每个数据收集指示可以用于控制单个数据项或者一组数据项的收集与否。示例性的,假设终端设备接收到至少两个数据收集指示信息,且分别为第一数据收集指示和第二数据收集指示,若第一数据指示信息的取值表示允许时,表示终端设备可以收集第一数据指示信息控制的单个数据项或一组数据项,若第二数据指示信息的取值表示禁止,则表示不允许终端设备收集第二数据收集指示信息控制的单个或一组数据项。
在另一种实现方式下,允许资源池使用相关的记录数据中的有些数据项不与任何能力指示信息关联,此时,这些数据项默认终端设备可以记录或收集。
可选的,在上述S702之后,该方法还可以包括如下步骤:
S703、网络设备向终端设备发送数据记录配置信息,该数据记录配置信息包括:数据记录时长配置信息和/或数据记录上报配置信息。
示例性的,该数据记录配置信息包括:数据记录时长配置信息和/或数据记录上报配置信息。其中,数据记录时长配置信息用于配置数据记录的时间长度。数据记录上报配置信息用于配置数据记录的上报信息。
可选的,上述数据记录上报配置信息可以包括如下类型配置中的至少一项:
A1、数据记录上报周期配置信息;
A2、数据记录上报重复次数配置信息;
A3、数据记录上报小区范围配置信息。
其中,数据记录上报周期配置信息用于确定数据记录上报的周期,比如:终端设备每200ms上报一次资源池使用相关的记录数据;可理解,本申请实施例并不对具体的上报周期取值进行限定。
数据记录上报重复次数配置信息用于确定数据记录上报的重复次数,比如:终端设备可以将上述资源池使用相关的记录数据上报多次,以保证网络设备能够成功接收;可理解,本申请实施例并不对具体的重复上报次数进行限定。
数据记录上报小区范围配置信息用于规定资源池使用相关的记录数据上报的小区范围,如果终端设备驻留的小区不是该数据记录上报小区范围配置信息内的小区,则不允许终端设备上报资源池使用相关的记录数据。
可选的,小区范围配置形式为如下任意一种:
至少一个跟踪区标识(tracking area code:TAC)、至少一个小区标识或者至少一个公共陆地移动网(public land mobile network:PLMN)标识。
其中,小区标识通过小区全球标识(cell global identifier:CGI)表示;或者,通过频点+物理小区标识(physical cell identifier:PCI)表示。
步骤S702中的配置信息和S703中的数据记录配置信息可以通过同一条消息发送或者通过不同消息分别发送,本申请对此不做限定。可选的,在本申请的实施例中,终端设备从网络设备接收到数据记录配置信息后,可以对其进行处理,例如,基于该数据记录配置信息,记录资源池使用相关的记录数据,随后执行S400,即通过第一消息向网络设备上报资源池使用相关的记录数据。
可选的,终端设备从网络设备接收到数据记录配置信息后,可以从中确定出数据记录时长配置信息和/或数据记录上报配置信息。
示例性的,假设数据记录配置信息中同时包括数据记录时长配置信息和数据记录上报配置信息,则终端设备可以根据数据记录时长配置信息,确定记录数据的时间长度,并在使用资源池中的资源时执行相应的记录过程,可以根据数据记录上报配置信息执行记录数据的上报过程。
可选的,在图7中,S400之前的S701、S702、S703均是可选步骤,本实施例对其不作限定。
可选的,当图7所示的实施例在图6所示的实施例基础上实现时,S701、S702、S703可以位于上述S601和S602之前,即终端设备向网络设备发送能力指示信息,网络设备向终端设备发送配置消息和/或数据记录配置信息后,终端设备可以向网络设备发送第二消息,并接收网络设备发送的第二消息的响应消息后,再向网络设备上报第一消息。对此,本实施例不作限定。
