具体实施方式
下面将结合附图,对本申请中的技术方案进行描述。为了便于理解本申请,下文先结合图1至图8介绍本申请实施例涉及的通信过程。
双连接通信场景
当前,随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此3GPP国际标准组织开始研发第五代(5th generation,5G)通信系统。5G的主要应用场景为:增强移动超宽带(enhanced mobile broadband,eMBB)、低时延高可靠通信(ultra reliability and low latency communication,URLLC)、大规模机器类通信(massive machine type communications,mMTC)。
eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,便如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
在新无线(new radio,NR)早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的长期演进(long term evolution,LTE)覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。
为了能够尽快实现5G网络部署和商业应用,3GPP在2017年12底前首先完成第一个5G版本,即EN-DC(LTE-NR dual connectivity)。图1是EN-DC的组网架构示意图。参见图1,EN-DC是以LTE基站(例如eNB)作为主节点(master node,MN)或主基站,以NR基站(例如gNB)作为辅节点(secondary node,SN)或辅基站的DC,并且MN和SN分别可以与演进分组核心(evolved packet core,EPC)网(即第四代(4th generation,4G)通信系统核心网)建立数据面连接,为终端设备与EPC之间的数据提供空口传输资源。其中,EPC可以包括移动管理节点功能(mobility management entity,MME)和/或服务网关(serving gate way,S-GW)。
需要说明的是,在图1所示的架构中,S1接口是LTE基站与EPC之间的通信接口。基于S1接口中传输的信息的类型不同,S1接口又可以分为S1-U接口和S1-C接口,其中,S1-U接口可以用于传输用户面数据,S1-C接口可以用于传输控制面信令。
下文结合图2至图3所示的两种组网方式为例,介绍EN-DC的双连接场景下终端设备与网络设备之间的连接方式。
参见图2,LTE eNB作为MN,与EPC之间建立有S1-U接口以及S1-C接口。gNB作为SN,与EPC之间建立有S1-U接口。在这种架构下,EPC和基站之间的控制面信令传输只能在EPC和LTE eNB之间传输,再由LTE eNB将特定的控制面信令转发给gNB。而用户面数据则可以在分别在EPC和LTE eNB之间以及EPC和gNB之间传输。
参见图3,LTE eNB作为MN,与EPC之间建立有S1-U接口以及S1-C接口。gNB作为SN,并不直接与EPC通信。在这种架构下,EPC和基站之间的控制面信令和用户面数据传输只能在EPC和LTE eNB之间传输,之后,由LTE eNB将特定的控制面信令和/或用户面数据传输给gNB。
需要说明的是,在图2和图3所示的组网方式中,MN和SN中都可以设置有RRC实体,以生成 RRC PDU,参见图4。但是同一个时刻终端设备通常只有一个RRC状态机且基于MN侧。
还需要说明的是,在LTE中信令承载可以包括信令无线承载(signaling radio bearer,SRB)0,SRB1,SRB2。而EN-DC在此基础上可以进一步支持SRB3。SRB3用于传输SN到终端设备之间的RRC信令,该信令承载的生成不需要和MN之间进行资源协商和UE能力协商。另外,为了提高SRB1和SRB2传输的可靠性,EN-DC中还可以支持分离SRB1(split SRB1)和split SRB2,即MN产生的RRC消息对应的分组数据汇聚协议协议数据单元(packet data convergence protocol protocol data unit,PDCP PDU)在SN侧重复传输一份。
本申请实施例提供的方法可用于各种多制式双连接(multiple RAT dual connectivity,MR-DC)架构。例如,4G通信系统与5G通信系统的双连接、5G通信系统与4G通信系统的双连接,或者5G通信系统与5G通信系统的双连接等等。
上述4G通信系统与5G通信系统的双连接可以包括:演进通用陆地无线接入(evolved universal terrestrial radio access,E-UTRA)系统和新无线(new radio,NR)系统的双连接(E-UTRA-NR dual connectivity,EN-DC),和5G核心网下的E-UTRA系统和NR系统的双连接(NG-RAN E-UTRA-NR dual connectivity,NGEN-DC)等。其中,EN-DC也可以称为选项3系列(option 3series)。
NGEN-DC也可以称为选项7系列(option 7series)。NG EN-DC是以LTE基站(例如ng-eNB)作为MN,以NR基站(例如gNB)作为SN的DC。与EN-DC不同的是,NG EN-DC中,MN和SN都可以连接5G核心网(5G core network,5GC),为终端设备与5GC之间的数据提供空口传输资源。
5G通信系统与4G通信系统的双连接可以包括NR系统和E-UTRA系统的双连接(NRE-UTRA dual connectivity,NE-DC)等。NE-DC也可以称为选项4系列(option 4series)。NE-DC是以NR基站(例如gNB)作为MN,以LTE基站(例如ng-eNB)作为SN,并且MN和SN分别可以与5GC有数据面连接,为终端设备与5GC之间的数据提供空口传输资源。
5G通信系统与5G通信系统的双连接可以包括NR系统与NR系统的DC。NR系统与NR系统的DC中,MN和SN都为NR的基站。
前文介绍了多种双连接的组网方式,下面结合图5至图7,对基于不同类型的主节点的双连接组网方式进行介绍。
图5是LTE eNB作为主节点的双连接(即EN-DC)组网方式的示例图。参见图5,LTE eNB为MN,NR gNB作为SN。在这种架构下,EPC和基站之间的控制面信令传输只能在EPC和LTE eNB之间传输,再由LTE eNB将特定的控制面信令转发给gNB。而用户面数据则可以在分别在EPC和LTE eNB之间以及EPC和gNB之间传输。
图6A是eLTE eNB与5GC的连接的示例图。图6B是图6A中eNB作为主节点的双连接(即NGEN-DC)组网方式的示例图。参见图6B,NR gNB可以与5GC相连,eLTE eNB可以与NR gNB组成NGEN-DC架构,其中,连接到5GC的eLTE eNB可以作为MN,NR gNB作为SN。这种架构下,MN和SN都可以连接5GC,MN和SN的用户面数据可以通过5GC进行聚合;而控制面信令只能在5GC和eNB之间传输,再由eNB转发给gNB。
图7A是NR gNB与5GC连接的示例图。图7B是一种图7A中gNB作为主节点的双连接(即NE-DC)组网方式的示例图。参见图7B,eLTE eNB可以与5GC相连,作为SN。这种架构下,MN和SN都可以连接5GC,MN和SN的用户面数据可以通过5GC进行聚合;而控制面信令只能在5GC和gNB之间传输,再由gNB转发给eNB。图7C是另一种图7A中gNB作为主节点的双连接(即NR-DC)组网方式的示例图。参见图7C,NR gNB可以与5GC连接,作为SN。这种架构下,MN和SN都可以连接5GC,MN和SN的用户面数据可以通过5GC进行聚合;而控制面信令只能由MN转发给SN。
下面仅以图8所示通信系统80为例,对本申请实施例适用的通信系统进行描述。
图8是本申请实施例提供的通信系统的架构示意图。参见图8,通信系统80可以包括网络设备801、网络设备802、网络设备805、终端设备803和终端设备804。图8仅为示意图,并不构成对本申请提供的技术方案的适用场景的限定。
图8中的网络设备即网络设备801、网络设备802或网络设备805可以是任意一种具有无线收发功能的设备。包括但不限于:LTE中的演进型基站(evolutional Node B,NodeB或eNB或e-NodeB),NR中的基站(gNodeB或gNB)或收发点(transmission receiving point/transmission reception point,TRP),3GPP后续演进的等。基站可以是:宏基站,微基站,微微基站,小站,中继站,或,气球站等。多个基站可以支持上述提及的同一种技术的网络,也可以支持上述提及的不同技术的网络。基站可以包含一个或多个共站或非共站的TRP。网络设备还可以是云无线接入网络(cloud radio access network,CRAN)场景下的无线控制器、集中单元(centralized unit,CU),和/或,分布单元(distributed unit,DU)。
图8中的终端即终端设备803或终端设备804是一种具有无线收发功能的设备,可以部署在陆地 上,包括室内或室外、手持、穿戴或车载;也可以部署在水面上(如轮船等);还可以部署在空中(例如飞机、气球和卫星上等)。所述终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality,VR)终端设备、增强现实(augmented reality,AR)终端设备、工业控制(industrial control)中的终端、车载终端设备、无人驾驶(self driving)中的终端、辅助驾驶中的终端、远程医疗(remote medical)中的终端、智能电网(smart grid)中的终端、运输安全(transportation safety)中的终端、智慧城市(smart city)中的终端、智慧家庭(smart home)中的终端等等。本申请的实施例对应用场景不做限定。终端有时也可以称为终端设备、用户设备(user equipment,UE)、接入终端、车载终端、工业控制终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端设备、无线通信设备、机器终端、UE代理或UE装置等。终端可以是固定的,也可以是移动的。
作为示例而非限定,在本申请实施例中,终端可以是可穿戴设备。可穿戴设备也可以称为穿戴式智能设备,是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称,如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上,或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备,更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能,例如:智能手表或智能眼镜等,以及只专注于某一类应用功能,需要和其它设备如智能手机配合使用,如各类进行体征监测的智能手环、智能首饰等。
另外,NR也可以独立部署。在5G通信系统中,最大的信道带宽可以是400MHz(wideband carrier),相比于LTE最大20M带宽来说,带宽很大。在NR独立组网(stand alone,SA)的系统中,通过CA可以提高速率,即用带宽换取速率。目前,通常在共站址且同RAT的载波之间作载波聚合。参与载波聚合的每个载波称之为分量载波(component carrier)。在分量载波中,承载信令传输并管理其他分量载波的分量载波称之为主载波,也叫主小区(primary cell,PCell);辅载波也叫辅小区(secondary cell,SCell)。其中,辅小区可以用来扩展带宽和提高速率,由主载波来决定何时添加或释放辅小区。
小区切换
小区切换(handover,HO)旨在提高通信系统为终端设备提供服务的连续性。在无线通信系统中,当终端设备从一个小区(又称“源小区”)移动到另一个小区时,为了保持通信终端设备需要切换到另一个小区(又称“目标小区”)。其中,小区可以是主小区(primary cell,PCell)或者主辅小区(primary secondary cell,PSCell)。通常,小区切换可以分为传统的切换机制和条件切换机制两种。
对于传统的切换机制而言,为了提高通信系统为处于连接态的终端设备提供服务的连续性,网络设备会在适当时机(例如,服务小区内终端设备的信号测量结果低于阈值)向终端设备发送切换命令,以指示终端设备进行小区切换。在一些实现方式中,上述切换命令可以是包含同步重配信息的RRC重配消息。
对于条件切换(conditional handover,CHO)机制而言,网络设备可以将一个或多个目标小区的配置,以及一个或多个条件切换目标小区关联的条件切换事件配置给终端设备,相应地,终端设备可以执行切换条件评估任务以评估上述一个或多个条件切换目标小区关联的条件切换事件是否满足。当上述一个或多个条件切换目标小区关联的一个或多个条件切换事件满足时,终端设备可以从源小区(或者称“当前服务小区”)切换到满足条件切换事件的对应条件切换目标小区。
R16标准版本中引入的CHO不支持候选小区配置包含辅小区(secondary cell group,SCG)组配置。为了支持MR-DC场景下的CHO,RAN3在R17讨论阶段进一步增强了Xn接口间的信令设计,以支持在CHO候选小区配置中包含一个SCG配置。这种配置方式的潜在问题在于,当终端设备根据执行条件确定目标PCell时,与PCell关联的PSCell的链路质量可能变得不够好,或者不是一个合适的PSCell,这就会导致终端设备无法成功接入PSCell。为了进一步优化移动性对于DC场景吞吐量的影响,R18移动性增强在R17具有辅小区组条件切换(CHO with SCG)的基础上进一步引入了对于PSCell评估流程,即称为具有候选辅小区组的条件切换(CHO with candidate SCGs),协议中的相关定义如下。
具有候选辅小区组的条件切换的定义为:当主小区和关联的主辅小区均满足执行条件,切换主小区,添加/变更主辅小区(A CHO with candidate SCG(s)is defined as a PCell change with PSCell addition/change that is executed by the UE when the execution conditions for both PCell and the associated PSCell are met)。终端设备基于接收到的包括候选辅小区组的条件切换配置,同时对候选主小区和候选的主辅小区的执行条件进行评估,一旦主小区切换或者主辅小区的切换被触发,终端设备停止评估上述执行条件(The UE starts evaluating the execution conditions for candidate PCell(s)and candidate PSCell(s)simultaneously upon receiving the CHO with candidate SCG(s)configuration,and stops evaluating the execution conditions once PCell change or PSCell change is triggered)。终端设备不执行包括候选辅小区组的条件切换,直到 主小区、与主小区关联的主辅小区的执行条件均满足(The UE does not execute CHO with candidate SCG(s)until the execution conditions for both PCell and the associated PSCell are met)。
相关技术中,网络设备可以基于终端设备上报的测量结果,为终端设备提供小区切换配置,如在支持CA/DC部署的场景中执行SCell添加/变更/释放或SCG添加/变更/释放过程。但是,这种方式存在一些的问题。
例如,如果终端设备的位置发生了变化,则基于上述小区切换配置终端设备可能无法接入目标小区。这是因为,上报的测量结果通常只能反映目标频点/小区当前的信道质量,而随着终端设备位置的变化,目标频点/小区相对于终端设备的无线链路情况也会随之发生变化。作为一个示例,基于当前的测量结果(如时刻1上报给网络设备的测量结果),频点1下的小区1具有最好的测量结果(如满足接入要求)。但实际上终端设备很快会移出小区1的覆盖范围,移动到频点2下的小区2。如果网络设备基于时刻1接收到的测量结果为终端设备提供小区切换配置,那么很可能会导致终端设备发生切换失败,造成业务中断。
又如,在支持CA/DC部署的场景中,基于终端设备上报的当前的小区测量结果,可能无法确定目标辅小区的相关信息,或者上报内容中存在一些不必要的信息,信令开销较大。这是因为,终端设备并不清楚哪些基站/小区之间可以构成CA/DC关系。因此,终端设备上报的测量结果可能不足以帮助网络设备确定目标SCell/SCG配置以及其激活/去激活状态,或者,上报内容中存在一些不必要的信息,造成较大的信令开销。
图9是本申请实施例提供的无线通信方法的流程示意图,以解决上述问题。图9所示的方法涉及网络设备和终端设备之间的交互,下文将站在终端设备与网络设备交互的角度,对本申请实施例提供的方法进行介绍。
图9所示的方法可以包括步骤S910。在步骤S910中,终端设备接收网络设备发送的第一配置信息,或者说,网络设备向终端设备发送第一配置信息。
上述第一配置信息与终端设备的第一上报关联。例如,第一配置信息可以用于确定第一上报的上报内容,和/或触发第一上报的条件。
在一些实施例中,第一上报可以与终端设备的小区切换关联,或者说,第一上报用于确定终端设备的小区切换关联的信息,如小区切换配置。
在一些实施例中,第一上报的上报内容可以包括第一预测信息,第一预测信息可以与小区测量结果的预测值关联。小区测量结果的预测值可以基于人工智能(artificial intelligence,AI)等技术获取。例如,AI技术可以用于预测终端设备的轨迹信息,以及目标频点/小区的信道质量。那么终端设备可以根据未来一段时间内终端设备的预测轨迹,上报未来一段时间内符合终端设备接入要求的小区/频点信息。如前文提到的示例,时刻1的测量结果中频点1下的小区1具有最好的测量结果,但是终端设备很快移出小区1的覆盖范围,移动到频点2下的小区2。采用本申请实施例提供的方法,终端设备可以向网络设备上报频点2下的小区2,而不上报频点1下的小区1,从而避免终端设备尝试接入小区1而产生业务中断。
在一些实施例中,第一配置信息可以包括频点/小区配置,频点/小区配置例如可以包括网络设备感兴趣的频点/小区。其中,频点/小区配置可以基于网络设备已知的信息确定,如基于终端设备或频点/小区的位置关系等确定。
在一些实施例中,第一上报的内容可以与第一配置信息中的频点/小区关联,也可以与第一配置信息中的频点/小区不关联。例如,终端设备可以只对第一配置信息中的频点/小区的相关信息进行测量、预测以及上报等,终端设备也可以对除第一配置信息中的频点/小区之外的频点/小区进行测量、预测以及上报等。
在一些实施例中,频点/小区配置可以包括以下中的一种或多种:第一频点/小区(如第一频点/小区列表);以及第二频点/小区(如第二频点/小区列表),第二频点/小区与至少部分第一频点/小区关联。其中,第一频点/小区配置包括至少一个小区/频点信息,第二频点/小区至少包括第一小区/频点配置中的全部/部分小区/频点关联一个小区/频点配置。第二频点/小区与第一频点/小区关联例如可以指第二频点/小区可以和第一频点/小区构成CA/DC关系。进一步地,频点/小区配置还可以包括频点/小区之间的关联关系,如小区1与小区3关联。
在支持CA/DC部署的场景中,终端设备可以基于上述频点/小区配置获知可以构成CA/DC关系的小区,从而确定相关的上报内容。也就是说,第一上报内容可以包括第一小区的信息以及与第一小区关联的第二小区的信息,从而有助于网络设备为终端设备提供合适的主小区配置信息以及辅小区配置信息。另外,在网络设备期待终端设备执行主小区组切换以及辅小区组切换的情况下,如果终端设备不清楚哪些基站/小区之间可以构成CA/DC关系,那么终端设备可能需要上报大量小区的信息,以获取合适 的主小区/辅小区配置信息。而基于上述频点/小区配置,终端设备可以针对性地确定上报内容,从而有助于节约信令开销。
在一些实施例中,第一配置信息可以包括触发第一上报的条件。基于触发第一上报的条件,有助于终端设备对上报内容进行筛选,从而有助于避免上报全部信息,如全部的预测信息而带来的信令开销。下面以第一上报的内容为前文提到的第一预测信息为例,对触发第一上报的条件进行介绍。
在一些实施例中,触发第一上报的条件可以与小区的信道质量,如参考信号接收功率(reference signal receiving power,RSRP)、参考信号接收质量(reference signal received quality,RSRQ)以及信号与干扰加噪声比(signal to interference plus noise ratio,SINR)中的一种或多种关联。以触发第一上报的条件与RSRP阈值关联为例,触发第一上报的条件可以包括第一预测信息满足预设条件,其中预设条件可以包括以下中的一种或多种:第一频点/小区的RSRP测量结果的预测值大于或等于第一RSRP阈值;第二频点/小区的RSRP测量结果的预测值大于或等于第二RSRP阈值;以及第一时间段和第二时间段存在时间重叠。其中,第二频点/小区与第一频点/小区关联,第一时间段为第一频点/小区的RSRP测量结果的预测值大于或等于第一RSRP阈值的时间,第二时间段为第二频点/小区的RSRP测量结果的预测值大于或等于第二RSRP阈值的时间。
上报大于RSRP阈值的频点/小区关联的第一预测信息,有助于提高终端设备接入目标小区的成功率。另外,考虑到支持CA/DC部署的场景,如果第一时间段和第二时间段存在时间重叠,则上报第一频点/小区以及第二频点/小区关联的第一预测信息,有助于终端设备实现主小区和主辅小区的同时接入。
在一些实施例中,触发第一上报的条件可以与时间信息关联。其中,时间信息可以包括获取第一预测信息的预测时间段和/或时间阈值,其中,所述时间阈值与所述第一预测信息满足所述预设条件的时间关联。
例如,触发第一上报的条件可以包括在预测时间段内(如未来A时间内),第一预测信息满足预设条件。由于第一上报的时刻与终端设备执行小区切换的时刻之间可能存在一定的时间间隔,因此,上报在预测时间段内满足预设条件的小区的相关信息,有助于提高终端设备接入目标小区的成功率。其中,预测时间段内例如可以包括终端设备执行小区切换的时刻。
又如,触发第一上报的条件可以包括第一预测信息满足预设条件的持续时间大于或等于时间阈值(可以包括第一时间阈值和/或第二时间阈值)。作为一个示例,触发第一上报的条件可以包括第一频点/小区的RSRP测量结果的预测值大于或等于第一RSRP阈值的持续时间大于或等于第一时间阈值,和/或第二频点/小区的RSRP测量结果的预测值大于或等于第二RSRP阈值的持续时间大于或等于第二时间阈值。上述触发第一上报的条件一方面可以进一步提高终端设备接入目标小区的成功率,另一方面可以避免终端设备服务小区的频繁切换。作为另一个示例,触发第一上报的条件可以包括第一时间段和第二时间段存在时间重叠的持续时间大于或等于第三时间阈值,从而有助于终端设备同时接入主小区和主辅小区的成功率。
另如,触发第一上报的条件包括在预测时间段内,第一预测信息满足预设条件,以及第一预测信息满足预设条件的持续时间大于或等于时间阈值。作为一个示例,触发第一上报的条件包括在未来A时间内,第一频点/小区的RSRP测量结果的预测值大于或等于第一RSRP阈值,且第一频点/小区的RSRP测量结果的预测值大于或等于第一RSRP阈值的持续时间大于或等于第一时间阈值。作为另一个示例,触发第一上报的条件包括在未来B时间内,第二频点/小区的RSRP测量结果的预测值大于或等于第二RSRP阈值,且第二频点/小区的RSRP测量结果的预测值大于或等于第二RSRP阈值的持续时间大于或等于第二时间阈值。
在一些实施例中,B的值可以大于A的值。在一些情况下,某个辅小区或主辅小区可能无法与主小区同时完成接入,但是辅小区或主辅小区可能会在终端设备完成主小区切换之后较短的时间内完成接入。那么,B的值大于A的值,有助于提高上述场景中终端设备接入辅小区或主辅小区的成功率。另外,这种情况下,网络设备可以将辅小区或主辅小区的配置信息提供给终端设备,但是去激活辅小区或主辅小区。
在一些实施例中,触发第一上报的条件可以与频点/小区的优先级信息关联。频点/小区的优先级信息例如可以包括以下中的一种或多种:第一频点/小区的优先级;第二频点/小区的优先级;第三频点/小区;以及优先级阈值。其中,第二频点/小区与第一频点/小区关联,第三频点/小区属于第一频点/小区或者第二频点/小区,且第三频点/小区的优先级高于第一频点/小区或者第二频点/小区中的其他频点/小区。也就是说,第三频点/小区为优先级较高的频点/小区。
在一些实施例中,频点/小区的优先级信息可以基于负载情况等确定。例如,当负载较重时,或者说待传输的数据量较大时,带宽较大的频点/小区,或者空闲的频点/小区的优先级较高。另外,频点/小区的优先级可以为预配置或预定义的固定优先级,频点/小区的优先级也可以为动态调整的,如可以基于 负载的变化情况动态调整。
在频点/小区的优先级信息包括频点/小区的优先级以及优先级阈值的情况下,触发第一上报的条件可以包括第一预测信息关联的频点/小区的优先级大于或等于优先级阈值。其中,优先级阈值例如可以包含在第一配置信息中,或者通过其他消息进行预配置。又如,优先级阈值也可以为协议预定义的。
在频点/小区的优先级信息包括第三频点/小区的情况下,触发第一上报的条件可以包括第一预测信息关联的频点/小区属于第三频点/小区。其中,第三频点/小区例如可以包含在第一配置信息中。
在一些实施例中,优先级信息的配置粒度可以针对每个频点,也可以针对每个小区。
在一些实施例中,触发第一上报的条件可以与概率阈值关联。这里提到的概率阈值可以与第一预测信息满足预设条件的概率关联。例如,触发第一上报的条件可以包括第一预测信息满足预设条件的概率大于或等于概率阈值。又如,触发第一上报的条件可以包括在预测时间段内第一预测信息满足预设条件的概率大于或等于概率阈值。另如,触发第一上报的条件可以包括在预测时间段内第一预测信息满足预设条件的持续时间大于或等于时间阈值的概率大于或等于概率阈值。这里提到预设条件可以包括前文提到的任意一种或多种预设条件,也可以为其他类型的预设条件。
在一些实施例中,触发第一上报的条件可以包括存在至少一个辅小区处于激活态,或者说触发第二频点/小区相关信息上报的条件包括存在至少一个辅小区处于激活态。如果存在至少一个辅小区处于激活态,那么系统可能工作在DC模式。此时,向网络设备上报可以与第一频点/小区构成DC关系的第二频点/小区关联的信息,如测量结果的预测值,可以辅助网络设备为终端设备提供相应的配置信息。如果没有辅小区处于激活态,终端设备可以不向网络设备上报第二频点/小区关联的信息,从而有助于节约信令开销。
对于主小区(如第一小区)以及主辅小区/辅小区(如第二小区),触发第一上报的上报条件可以相同,也可以不同。例如,第一小区关联的预设条件和第二小区关联的预设条件可以不同,如前文提到的第一RSRP阈值和第二RSRP阈值可以不同。又如,第一小区关联的时间信息和第二小区关联的时间信息可以不同。作为一个示例,第一小区关联的预测时间段和第二小区关联的预测时间段可以不同,如前文提到的A时间和B时间。作为一个示例,第一小区关联的时间阈值和第二小区关联的时间阈值可以不同,如前文提到第一时间阈值以及第二时间阈值。另如,第一小区关联的优先级阈值和第二小区关联的优先级阈值可以不同。再如,第一小区关联的概率阈值和第二小区关联的概率阈值可以不同。
需要说明的是,对于第一小区和第二小区,触发第一上报的上报条件可以部分相同,部分不同。例如,第一小区关联的预设条件与第二小区关联的预设条件不同,但是第一小区关联的概率阈值和第二小区关联的概率阈值可以相同。
需要说明的是,触发第一上报的条件可以包括上文介绍的一种或多种条件,即包括以下中的一种或多种:第一预测信息满足预设条件;在预测时间段内,第一预测信息满足预设条件;第一预测信息满足预设条件的持续时间大于或等于时间阈值;第一预测信息满足预设条件的概率大于或等于概率阈值;第一预测信息关联的频点/小区的优先级大于或等于优先级阈值;以及第一预测信息关联的频点/小区属于第三频点/小区。
在一些实施例中,终端设备可以向网络设备发送第一预测信息,或者说,网络设备可以接收终端设备发送的第一预测信息。其中,第一预测信息可以基于上述第一配置信息确定。例如,终端设备可以对至少一个频点下的至少一个小区的测量结果进行预测(如基于AI模型获取测量结果的预测值),并基于测量结果的预测值以及第一配置信息(如第一配置信息中指示的触发第一上报的条件)确定向网络设备上报的第一预测信息。
在一些实施例中,第一预测信息可以包括以下中的一种或多种:终端设备服务小区测量结果的预测值;目标频点/小区测量结果的预测值;以及概率信息。
终端设备服务小区测量结果的预测值例如可以包括预测时间段内,如未来A时间内的测量结果的预测值。
目标频点/小区例如可以包括上述第一频点/小区中的一个或多个频点/小区,又如可以包括上述第一频点/小区中的一个多个频点/小区以及第二频点/小区中的一个或多个频点/小区。参见图10,终端设备的邻小区可以包括小区1、小区2、小区3、小区4以及小区5,其中,小区2、小区3、小区4以及小区5与小区1关联。目标频点/小区可以包括小区1,也可以包括小区1以及小区2、小区3、小区4以及小区5。目标频点/小区测量结果的预测值例如可以包括未来A时间内,小区1测量结果的预测值,和/或未来B时间内,小区2至小区5测量结果的预测值。
在一些实施例中,第一预测信息中的概率信息可以包括目标频点/小区满足预设条件的概率。这里提到的预设条件可以为第一配置信息指示的条件,如前文提到的任意一种或多种预设条件,也可以为其他预设条件。通过上报目标频点/小区满足预设条件的概率信息,可以辅助网络设备为终端设备提供小 区切换配置,有助于提供配置信息的准确性。
在一些实施例中,终端设备可以基于终端设备移动轨迹的预测信息(或者说终端设备的预测移动轨迹),对终端设备的服务小区和/或邻小区的测量结果进行预测。图11示出了终端设备的一种预测移动轨迹1110。基于预测移动轨迹1110,终端设备可以对服务小区以及邻小区(小区1至小区5)的测量结果进行预测。
在一些实施例中,第一预测信息可以辅助网络设备释放/添加辅小区,以及对辅小区执行激活/去激活。例如,第一预测信息中包括可以构建CA/DC关系的小区(如第一小区和第二小区)关联的信息,该信息可以辅助网络设备添加/释放辅小区。作为一个示例,第一预测信息中可以包括第一小区和第二小区可以构建CA/DC关系的时间信息,基于该时间信息网络设备可以确定添加/释放辅小区的时间和/或对辅小区执行激活/去激活的时间。在第一小区和第二小区无法同时完成接入(如第二小区在一段时间后才能满足接入条件)的情况下,终端设备可能会在完成第一小区切换之后完成第二小区的接入。这种情况下,网络设备可以提前添加第二小区,但是去激活第二小区。另外网络设备可以在第二小区满足接入条件时,或第二小区满足接入条件之前,激活第二小区。
在一些实施例中,终端设备可以接收网络设备发送的第二配置信息,第二配置信息包括终端设备的候选小区的配置信息。例如,第二配置信息可以基于前文所述的第一预测信息确定。
候选小区的配置信息例如可以包括候选主小区组(master cell group,MCG)配置信息;和/或候选SCG配置信息,其中,候选SCG与至少部分候选MCG关联。
在一些实施例中,第二配置信息还包括以下中的一种或多种:第一指示信息,用于指示终端设备延迟接入候选小区中的SCG;第二指示信息,用于指示终端设备激活和/或接入候选小区中SCG的时间信息;以及第三配置信息,用于指示保留配置信息的候选小区,和/或,激活和/或接入保留配置信息的候选小区的时间信息。
第一指示信息例如可以用于指示终端设备延迟向候选小区中的SCG发起随机接入。在一些情况下,如辅小区在一段时间后才满足接入条件等,终端设备可能无法同时接入主小区和辅小区。这种情况下,第二配置信息包括第一指示信息,有助于避免提前接入辅小区而造成的接入失败。
在一些实施例中,第二指示信息可以包括第一定时器和/或第三阈值,其中,第三阈值可以与SCG信号质量测量结果的预测值关联。例如,目标SCG信号质量测量结果和/或测量结果的预测值大于或等于第三阈值时,激活目标SCG和/或向目标SCG发起随机接入。终端设备应用目标SCG配置后,在终端设备认为目标SCG为去激活态,和/或,不向目标SCG发起随机接入的情况下,当目标SCG的测量结果和/或测量结果的预测值大于第三阈值时,激活目标SCG和/或向目标SCG发起随机接入。这里提到的第三阈值例如可以为第三RSRP阈值。又如,第二指示信息可以包括第一定时器的时长配置。作为一个示例,当第一定时器超时时,激活目标SCG和/或向目标SCG发起随机接入。终端设备执行条件切换后,在认为目标SCG的状态为去激活态,和/或,不向目标发起随机接入的情况下,启动第一定时器,并在第一定时器超时后,激活目标SCG和/或向目标SCG发起随机接入。
在一些实施例中,终端设备完成条件切换后,可以保留一些候选小区的配置信息,从而辅助终端设备执行下一次小区切换,有助于避免信令开销。
第三配置信息例如可以用于指示保留配置信息的候选小区,或者说,第三配置信息用于指示保留哪些候选小区的配置信息。作为一个示例,第三配置信息可以通过候选小区配置的索引指示保留的候选小区配置信息。以第二配置信息中包含4套候选小区配置(对应的索引为1到4)为例,第三配置信息可以指示终端设备在完成条件切换后,保留的候选小区配置信息,如索引值为4对应的候选小区配置。相应的,终端设备可以释放出保留配置信息的候选小区之外的其他小区的配置信息。
第三配置信息又如可以包括第二定时器,如第二定时器的时长配置。保留的候选小区的配置信息可以用于下一次小区切换。其中,第二定时器可以用于指示激活和/或接入保留配置信息的候选小区的时间信息。例如,当第二定时器超时时,终端设备可以执行以下中的一种或多种:应用保留的候选小区配置信息,激活保留配置信息的候选小区以及接入保留配置信息的候选小区。
前文对终端设备基于网络设备配置的第二配置信息确定目标候选SCG相关信息的方法,下面对终端设备基于前文提到的第一预测信息确定目标候选SCG相关信息的方法。这里提到的目标候选SCG相关信息例如可以包括激活/去激活目标候选SCG的时间信息和/或接入目标候选SCG的时间信息等。
在一些实施例中,终端设备基于第一预测信息确定能否同时接入候选MCG和候选SCG(候选SCG与至少部分候选MCG关联)。例如,终端设备可以基于第一预测信息确定时刻3终端设备是否同时处于候选MCG和候选SCG覆盖范围内。又如,终端设备可以基于第一预测信息确定时刻3候选MCG和候选SCG是否均满足接入条件,或者候选MCG满足接入条件的时间段以及候选SCG满足接入条件的时间段。作为一个示例,如果时刻3终端设备同时处于候选MCG和候选SCG的覆盖范围内,以及候 选MCG和候选SCG均满足接入条件,则终端设备可以在时刻3同时接入候选MCG和候选SCG。否则,终端设备在时刻3无法同时接入候选MCG和候选SCG。
在一些实施例中,如果终端设备无法同时接入候选MCG和候选SCG,则终端设备执行第一操作。第一操作包括以下中的一种或多种:应用候选MCG和候选SCG的配置;去激活候选SCG;延迟向候选SCG发起随机接入;以及向第四小区对应的网络设备发送第三指示信息;其中,第四小区为候选MCG中终端设备接入的小区,第三指示信息用于指示候选SCG关联的信息。
例如,终端设备无法同时接入候选MCG和候选SCG,但是一段时间后候选SCG可能满足接入要求:如终端设备移动到候选SCG的覆盖范围,或者候选SCG的测量结果/测量结果的预测值满足条件切换的执行条件。这种情况下,终端设备可以执行第一操作。其中,提前应用候选MCG和候选SCG的配置有助于降低切换时延。而去激活候选SCG和/或延迟向候选SCG发起随机接入,可以避免在SCG不满足接入条件时的无效接入。
第三指示信息例如可以包括以下中的一种或多种:与候选SCG关联的索引;是否延迟向候选SCG发起随机接入;以及是否对候选SCG去激活。在终端设备无法同时接入候选MCG和候选SCG时,终端设备向第四小区对应的网络设备发送第三指示信息,可以使得网络设备与终端设备对齐理解候选SCG相关的信息。
需要说明的是,上文提到的候选MCG和候选SCG可以为终端设备拟接入的MCG和SCG,也可以替换为目标MCG和目标SCG。
在一些实施例中,当目标SCG的测量结果和/或测量结果的预测值满足接入条件时,可以激活目标SCG和/或向目标SCG发起随机接入。
需要说明的是,本申请中提到的“频点/小区”可以替换为频点和/或小区。
需要说明的是,本申请实施例提供的方法可以应用于条件切换过程,也可以应用于其他类型的小区切换过程。
本申请实施例通过在小区切换过程中引入了小区测量结果的预测值,使得网络设备可以为终端设备提供更为准确的小区配置等信息,从而有助于降低移动性对系统吞吐量的影响。另外,网络设备可以为终端设备配置一些信息,以辅助第一上报,从而有助于提高系统性能。例如,网络设备可以为终端设备配置一些准则,如触发第一上报的条件,对上报对象进行筛选,有助于节约上报开销。另外,考虑到终端设备并不知晓网络设备的部署方式以及小区可接入情况,网络设备可以为终端设备提供与第一频点/小区关联的第二频点/小区,从而辅助终端设备对上报内容进行筛选,有助于节约开销。以前文提到的具有候选辅小区组的条件切换为例,在本申请实施例中,网络设备可以获知终端设备是否/何时能够同时接入PCell和/或PSCell,或者接入不同PCell&PSCell对的概率,从而为终端设备提供更合适的配置信息,有助于提高接入成功的概率。
