本发明涉及通信领域,尤其涉及一种数据传输方法、装置、存储介质、芯片及相关设备。
从UE(User Equipment,用户设备)侧来看,双连接(Dual Connectivity,DC)的场景涉及三种不同的承载类型,分别为MCG Bearer(Master Cell Group Bearer,主小区组承载)、SCG Bearer(Secondary Cell Group Bearer,辅小区组承载)和Split Bearer(分离承载)。而从网络侧来看,这三种承载既可以在MN终结(MN Terminated),也可以在SN终结(SN Terminated)。其中,MN Terminated Bearers(在MN终结的承载)对于CN(Core Network,核心网)用户面连接是终结在MN(Master Node,主基站)的,即PDCP(Packet Data Convergence Protocol,分组数据汇聚协议)层在MN;SN Terminated Bearers(在SN终结的承载)对于CN用户面连接是终结在SN(Secondary Node,辅基站)的,即PDCP层在SN。而在Uu用户面,针对不同承载类型,会与MCG或者SCG资源相关,即对于MCG Bearers,只有MCG无线资源会相关;对于SCG Bearers,只有SCG无线资源会相关;对于Split Bearer,MCG无线资源和SCG无线资源都会相关。其中,Split Bearer包括MCG(Master Cell Group,主小区组)分支(leg)的承载和SCG(Secondary Cell Group,辅小区组)分支(leg)的承载。

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,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
需要说明的是,本申请的说明书和权利要求书中及上述附图中的属于“第一”、“第二”、“第三”等是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的本申请的实施例能够以除了在这里图示或描述以外的顺序实施。此外,术语“包括”及其任何变形,意图在于覆盖不排他的包含, 例如,包含了一系列步骤或单元的过程、方法、***、产品或服务器不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
请参阅图1,图1为本申请实施例提供的一种数据传输方法的场景图。如图1所示,在该数据传输场景中,用户设备101处于双连接(Dual-Connectivity,DC)状态,与MN(MeNB,主基站)102和SN(SeNB,辅基站)103通信,MN 102与SN 103通信,MN 102和SN 103均可与核心网104通信。MN 102向SN 103发送SCG Suspension Requset(辅小区组挂起请求);SN 103根据接收到的SCG Suspension Requset使SCG(Secondary Cell Group,辅小区组)处于SCG Suspension(辅小区组挂起)状态,并向MN 102反馈SCG Suspension Complete(辅小区组挂起完成)的信息;MN 102根据SCG Suspension Complete的信息向用户设备发送Indication to Suspend SCG(已挂起辅小区的指示);用户设备根据Indication to Suspend SCG进入SCG挂起状态,PSCell(Primary SCG Cell,主辅小区)配置长周期的DRX(Discontinuous Reception,不连续接收),各Scell(Secondary Cell,辅小区)处于Dormancy(休眠)状态。
其中,网络设备可通过RRC(Radio Resource Control,无线资源控制)消息配置用户设备进入或离开SCG挂起状态,也可通过MAC CE(Media Access Control Control Element,媒体访问控制层控制元素)或Lower Layer Indication(低层指示信息)指示用户设备进入或离开SCG挂起状态。所述Lower Layer Indication可以为PHY(物理层)指示信息或DCI(Downlink Control Information,下行控制信息)等。
本申请实施例中,所述SCG Suspension,可以是SN或者SCG去激活,或者可以是SN或者SCG挂起。
本申请实施例中,对于用户设备一侧,在SCG处于SCG Suspension状态的情况下,若有需要SCG Bearer(Secondary Cell Group Bearer,辅小区组承载)或配置成Split Bearer(分离承载)形式的SCG分支(leg)的承载传输的业务数据,即有需要通过SCG无线资源传输的业务数据,则根据接收到的网络设备发送的配置信息,将业务数据由SCG切换MCG(Master Cell Group,主小区组)传输,即用户设备将业务数据先发送给MN 102,再由MN 102将业务数据转发给SN 103,进而可由SN 103将业务数据发送给核心网104。
需要说明的是,目前,Split Bearer可将SCG分支或者MCG分支配置成主路径(Primary Path),即若用户设备需要传输的数据量小于传输数据量门限,则用户设备只会在主路径上传输业务数据;在SCG处于SCG Suspension状态的情况下,所述配置成Split Bearer形式的SCG分支的承载传输业务数据,是指将Split Bearer的SCG分支配置成主路径,即若用户设备需要传输的数据量小于传输数据量门限,则用户设备只会在Split Bearer的SCG分支上传输业务数据,即需要激活SCG,比如:完成PSCell的TA(Timing Advance,定时提前)维护,Beam(波束)管理以及信道质量上报等,才能传输该业务数据,增加了传输数 据的时延和能耗。
本申请实施例中,在SCG处于SCG Suspension状态的情况下,若有需要SCG Bearer(Secondary Cell Group Bearer,辅小区组承载)或配置成Split Bearer(分离承载)形式的SCG分支(leg)的承载传输的业务数据,并不激活SCG,而是将业务数据由SCG切换MCG传输,避免了激活SCG增加传输业务数据的时延和能耗。
其中,将业务数据由SCG切换MCG传输,即是将业务数据由SN 103切换到MN 102传输,再即是将业务数据由SCG Bearer和/或Split Bearer的SCG分支的承载切换到MCG Bearer和/或Split Bearer的MCG分支的承载传输,也即是将RLC(Radio Link Control,无线链路控制子层)Bearer由SCG切换到MCG,还即是PDCP(Packet Data Convergence Protocol,分组数据汇聚协议)路由规则指示根据配置信息,将数据包由SN 103 RLC切换到MN 102 RLC传输,还即是从使用SCG无线资源切换到使用MCG无线资源传输业务数据。其中,用于传输需要在SCG传输的业务数据的相关承载可以是一个或多个。本申请实施例中,所述多个是指至少两个。
本申请实施例中,所述网络设备包括MN 102和SN 103。所述配置信息可由核心网104发送给SN 103,由SN 103直接发送给用户设备或由SN 103通过MN 102发送给用户设备;所述配置信息再可由MN 102配置并发送给用户设备;所述配置信息还可由SN 103配置并通过MN 102发送给用户设备,或者由SN 103配置并发送给用户设备,网络设备还可通过其他方式配置或发送配置信息给用户设备,在此不对网络设备配置或发送配置信息给用户设备的方式作限定。
本申请实施例中,所述配置信息可包括:切换条件,和/或,无线资源配置信息。其中,无线资源配置信息包括辅小区组SCG无线资源配置信息和主小区组MCG无线资源配置信息,和/或,无线资源配置信息包括分离承载Split Bearer配置信息。
本申请实施例中,若所述配置信息包括:切换条件,则网络设备通过所述配置信息指示用户设备执行:若确定满足所述切换条件,则将业务数据由所述辅小区组SCG切换到所述主小区组MCG传输。
需要说明的是配置信息可用于指示用户设备执行若SCG处于挂起状态,则将业务数据由所述辅小区组SCG切换到所述主小区组MCG传输,进而配置信息可不携带切换条件。
本申请实施例中,若所述配置信息包括:辅小区组SCG无线资源配置信息和主小区组MCG无线资源配置信息,则所述配置信息,用于指示所述用户设备使用辅小区组SCG无线资源传输业务数据或使用主小区组MCG无线资源传输业务数据。具体地,网络设备在将传输业务数据的相关的一个或多个无线承载配置成SCG承载的同时,增加与该SCG承载对应的MCG承载,并指示用户设备只通过SCG承载和MCG承载中的一种传输业务数据。
本申请实施例中,所述配置信息包括:分离承载Split Bearer配置信息;所述配置信息, 用于指示用户设备使用所述辅小区组SCG无线资源传输业务数据或使用所述主小区组MCG无线资源传输业务数据,即分离承载Split Bearer配置信息指示配置一种特殊配置的Split Bearer,该特殊配置的Split Bearer配置成只通过SCG无线资源和MCG无线资源中的一项传输业务数据。其中,所述分离承载Split Bearer配置信息包括:辅小区组SCG无线资源配置信息和主小区组MCG无线资源配置信息。
本申请实施例中,针对一个或多个无线承载,所述配置信息可以包含一个或多个Split Bearer配置信息,即每个无线承载分别对应一个Split Bearer配置信息。网络设备可在任意无线承载配置的Split Bearer配置信息中增加指示信息,该指示信息用于指示用户设备使用所述辅小区组SCG无线资源传输业务数据或使用所述主小区组MCG无线资源传输业务数据,即指示只通过SCG无线资源和MCG无线资源中的一项传输业务数据。
进一步,网络设备指示用户设备在有需要通过SCG无线资源传输的业务数据的情况下,将该业务数据由所述辅小区组SCG切换到主小区组MCG以通过MCG无线资源传输该业务数据;但在不满足配置信息中的切换条件,和/或,符合激活辅小区组的条件,和/或,用户设备接收到网络设备发送的第一指示信息的情况下,用户设备通过SCG传输该业务数据,即激活SCG,使PSCell处于Activated(激活状态)且未处于Dormancy状态,从而通过SCG传输业务数据。
具体地,MN 102向SN 103发送SCG Activation Request(SCG激活请求);SN 103根据SCG Activation Request激活SCG,并向MN 102反馈SCG Activation Complete(辅小区组激活完成)的信息;MN 102根据SCG Activation Complete的信息向用户设备发送Indication to Activation SCG(已激活辅小区的指示);用户设备根据该Indication to Activation SCG进入SCG激活状态,若TA(Timing Advance,定时提前)没有维持,则用户设备在PScell发起随机接入过程与SN进行通信,以传输业务数据。
需要说明的是,若SCell(或PSCell)处于Deactivated(去激活状态,或称:非激活状态),则用户设备不能在该SCell(或PSCell)执行传输业务数据,接收参考信号和做测量上报等操作;若SCell(或PSCell)处于Activated且未处于Dormancy状态,则可在该SCell(或PSCell)传输业务数据;若SCell(或PSCell)处于Dormancy状态,则用户设备可在该SCell(或PSCell)执行CSI(Channel State Information,信道状态信息)测量和/或Beam管理等操作,但不能传输业务数据。其中,Activated引入Dormancy状态,主要为了节能和快速恢复该SCell(或PSCell)的数据传输。
进一步,网络设备在接收到待传输的DL(DownLink,下行)数据,也可根据切换条件或根据网络设备的实际传输情况,确定不用激活SCG,将DL数据通过SN 103转发给MN 102进行调度。其中,网络设备可接收核心网104发送的待传输给用户设备的DL数据。
本申请实施例中,若辅小区组SCG未处于辅小区组挂起SCG Suspension状态,则用户设备与网络设备对于配置的SCG Bearer或者特殊配置的Split Bearer均通过SCG传输业务 数据,即通过SN 103传输业务数据,也即通过SCG无线资源传输业务数据,还即是通过SCG Bearer或Split Bearer中SCG分支的承载传输业务数据。
