具体实施方式
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,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不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,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”所区别的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”一般表示前后关联对象是一种“或”的关系。
值得指出的是,本申请实施例所描述的技术不限于长期演进型(Long Term Evolution,LTE)/LTE的演进(LTE-Advanced,LTE-A)系统,还可用于其他无线通信系统,诸如码分多址(Code Division Multiple Access,CDMA)、 时分多址(Time Division Multiple Access,TDMA)、频分多址(Frequency Division Multiple Access,FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access,OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access,SC-FDMA)和其他系统。本申请实施例中的术语“系统”和“网络”常被可互换地使用,所描述的技术既可用于以上提及的系统和无线电技术,也可用于其他系统和无线电技术。然而,以下描述出于示例目的描述了新空口(New Radio,NR)系统,并且在以下大部分描述中使用NR术语,尽管这些技术也可应用于NR系统应用以外的应用,如第6代(6th Generation,6G)通信系统。
图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络节点12。其中,终端11也可以称作终端设备或者用户终端(User Equipment,UE),终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)或称为笔记本电脑、个人数字助理(Personal Digital Assistant,PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer,UMPC)、移动上网装置(Mobile Internet Device,MID)、可穿戴式设备(Wearable Device)或车载设备(Vehicle UE,VUE)、行人终端(Pedestrian UE,PUE)等终端侧设备,可穿戴式设备包括:手环、耳机、眼镜等。需要说明的是,在本申请实施例并不限定终端11的具体类型。网络节点12可以是基站或核心网,其中,基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station,BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set,BSS)、扩展服务集(Extended Service Set,ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点、发送接收点(Transmitting Receiving Point,TRP)或所述领域中其他某个合适的术语,只要达到相同的技术效果,所述基站不限于特定技术词汇。
为了方便理解,以下对本申请实施例涉及的一些内容进行说明:
一、双连接(Dual Connectivity,DC)、载波聚合(Carrier Aggregation,CA)。
DC即为UE提供两个网络节点(如接入网网元)的资源,其中一个网络 节点称为主节点(Master Node,MN),另一个称为辅节点(Secondary Node,SN)。在每个网络节点,使用了CA技术,即为UE配置由该节点控制的一系列服务小区,也称小区组(Cell Group)。MN控制的为主小区组(Master Cell Group,MCG),SN控制的为辅小区组(Secondary Cell Group,SCG)。每个小区组都包含一个特殊小区(Special Cell,SpCell)和一系列辅小区(Secondary Cell,Scell)。在MCG中特殊小区称为主小区(Primary Cell,PCell),在SCG中特殊小区称为主辅小区(Primary Secondary Cell,PSCell)。在一个小区组中SpCell使用主载波,而其他辅小区使用辅载波,一个小区组内的资源调度由SpCell进行。
二、SCG挂起(suspended)。
UE可以在判断SCG发生失败时,自动将SCG挂起,然后向MN节点上报SCG失败信息。
UE也可以在网络侧的控制下将SCG挂起,例如,当UE很长一段时间都是低数据量传输时,网络侧可以将SCG暂时挂起,而不是直接将SCG删除,等较大数据量传输时再添加回来。将SCG暂时挂起,可以使终端在较长一段时间内以更加省电的方式工作,同时当有大量数据需求时可以较快地恢复SCG。
在本申请实施例中,在终端的SCG处于挂起状态的情况下,终端断开与SCG的连接,从而可以节省终端的耗电;在恢复了终端的SCG的情况下,终端与SCG重新建立连接,从而可以通过SCG进行数据传输,提高数据传输的速率。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的SCG处理方法进行详细地说明。
参见图2,图2是本申请实施例提供的SCG处理方法的流程图之一。本申请实施例的SCG处理方法可以应用于终端。进一步地,所述终端可以处于RRC连接态,且工作在双连接(Multi-RAT Dual Connectivity,MR-DC)模式,但不仅限于此。
如图2所示,应用于终端的SCG处理方法可以包括以下步骤:
步骤201、在所述终端的辅小区组SCG处于挂起状态时,使用目标资源 恢复所述终端的SCG。
在本申请实施例中,所述目标资源可以但不仅限于包括以下任意一项:随机接入信道(Random Access Channel,RACH)资源;调度请求(Scheduling Request,SR)资源。在实际应用中,所述目标资源可以由网络侧配置、协议约定或终端决定,本申请实施例对此不做限定。
具体实现时,所述在所述终端的辅小区组SCG处于挂起状态时,使用目标资源恢复所述终端的SCG,可以包括:
在所述终端的辅小区组SCG处于挂起状态时,判断是否满足SCG恢复条件;在满足所述SCG恢复条件的情况下,使用目标资源恢复所述终端的SCG;
其中,满足所述SCG恢复条件可以但不仅限于包括以下任意一项:
所述终端的待传输数据的数量大于第一阈值;
接收到第一指示信息,所述第一指示信息指示所述终端恢复SCG。
需要说明的是,本申请实施例并不限定触发所述终端的SCG进入挂起状态的触发条件。具体实现时,所述终端可以主动触发将SCG置于挂起状态,也可以被动触发将SCG置于挂起状态。
可选的,所述触发条件可以但不仅限于包括以下至少一项:
所述终端的SCG发生失败;
接收到第二指示信息,所述第二指示信息用于指示所述终端将SCG置于挂起状态。
本实施例的SCG处理方法,在所述终端的辅小区组SCG处于挂起状态时,使用目标资源恢复所述终端的SCG;其中,所述目标资源包括以下任意一项:随机接入RACH资源;调度请求SR资源。可见,本实施例解决了SCG挂起之后的SCG的恢复问题,从而可以满足终端大数据量传输的需求。
在本申请实施例中,可选的,在所述目标资源为所述RACH资源的情况下,所述终端的SCG通过在所述RACH资源上发起的RACH过程恢复;
在所述目标资源为SR资源的情况下,所述终端的SCG通过在所述SR资源上发起的SR过程恢复。
为方便理解,具体说明如下:
在所述目标资源为所述RACH资源的情况下,所述使用目标资源恢复所述终端的SCG,可以包括:
在所述RACH资源上发起RACH过程,所述RACH过程用于请求恢复所述终端的SCG。
具体实现时,本申请实施例并不限定所述RACH过程的类型,可选的,所述RACH过程可以是4步RACH过程或2步RACH过程。
在所述目标资源为SR资源的情况下,所述使用目标资源恢复所述终端的SCG,可以包括:
在所述SR资源上发起SR过程,所述SR过程用于请求恢复所述终端的SCG。
可见,通过上述方式,终端可以通过RACH过程或SR过程实现SCG的快速恢复,进而可以满足终端大数据量传输的需求。
在本申请实施例中,可选的,所述使用目标资源恢复所述终端的SCG,包括:
使用目标资源向第一网络节点发送SCG恢复请求消息,所述SCG恢复请求消息包括以下至少一项:用于指示恢复所述终端的SCG的第一标识信息、第二标识信息或第三标识信息;所述终端恢复所述终端的SCG的原因值;
其中,所述第二标识信息由第二网络节点通过截短所述第一标识信息得到,所述第三标识信息由所述终端通过截短所述第一标识信息得到。
在本可选实施方式中,终端可以通过向第一网络节点发送SCG恢复请求消息,用于请求恢复所述终端的SCG。若所述终端的SCG通过在所述RACH资源上发起的RACH过程恢复,则对于4步RACH过程,所述SCG恢复请求消息可以承载于4步RACH过程的消息(Message,Msg)3中;对于2步RACH过程,所述SCG恢复请求消息可以承载于2步RACH过程的MsgA中。若所述终端的SCG通过在所述SR资源上发起的SR过程恢复,则所述SCG恢复请求消息可以承载于SR过程的SR请求消息中。
具体实现时,所述SCG恢复请求消息包括以下至少一项:用于指示恢复所述终端的SCG的第一标识信息、第二标识信息或第三标识信息;所述终端恢复所述终端的SCG的原因值。
所述第一标识信息、所述第二标识信息和所述第三标识信息均可以用于指示恢复所述终端的SCG,也就是说,第一网络节点获取到所述第一标识信息、所述第二标识信息和所述第三标识信息中的任意一个,即可以知晓所述SCG恢复请求消息用于请求恢复所述终端的SCG。
在本可选实施方式中,所述第二标识信息由第二网络节点通过截短所述第一标识信息得到,所述第三标识信息由所述终端通过截短所述第一标识信息得到。也就是说,所述第二标识信息和所述第三标识信息均可以通过截短所述第一标识信息得到,但所述第二标识信息由第二网络节点生成,第三标识信息由终端生成。所述第二标识信息和所述第三标识信息可视为所述第一标识信息的截短格式的标识信息。
具体实现时,所述第一标识信息和所述第二标识信息可以由第二网络节点配置,所述第三标识信息可以由终端自主生成。
第一实现方式中,第二网络节点可以仅配置所述第一标识信息。
第二实现方式中,第二网络节点可以同时配置所述第一标识信息和所述第二标识信息。
如:在长期演进(Long Term Evolution,LTE)系统中,第二网络节点可以仅配置所述第一标识信息;在NR系统中,第二网络节点可以同时配置所述第一标识信息和所述第二标识信息。
对于上述第一实现方式,终端可以生成所述第三标识信息;对于上述第二实现方式,由于第二网络节点配置有所述第二标识信息,因此,终端可以生成所述第三标识信息。
在本可选实施方式中,若所述SCG恢复请求消息包括用于指示恢复所述终端的SCG的第一标识信息、第二标识信息或第三标识信息,则终端可以通过以下方式决定是在所述SCG恢复请求消息携带那个标识信息:
检测所述SCG恢复请求消息可携带的比特数是否大于第二阈值;
在所述SCG恢复请求消息可携带的比特数大于所述第二阈值的情况下,决定在所述SCG恢复请求消息中携带所述第一标识信息;
在所述SCG恢复请求消息可携带的比特数小于或等于所述第二阈值的情况下,决定在所述SCG恢复请求消息中携带所述第二标识信息或第三标识 信息。
进一步地,在所述SCG恢复请求消息可携带的比特数小于或等于所述第二阈值的情况下,检测第二网络节点是否配置有所述第二标识信息;若所述第二网络节点配置有所述第二标识信息,则决定在所述SCG恢复请求消息中携带所述第二标识信息;否则,所述终端生成所述第三标识信息,并决定在所述SCG恢复请求消息中携带所述第三标识信息。
可见,通过上述方式,终端可以通过向第一网络节点发送SCG恢复请求消息请求恢复所述终端的SCG,规范了恢复所述终端的SCG的流程。
在本申请实施例中,可选的,所述使用目标资源向第一网络节点发送SCG恢复请求消息之后,所述方法还包括:
使用所述目标资源接收所述第一网络节点发送的所述SCG恢复请求消息的响应消息;
其中,所述响应消息携带SCG配置信息,所述SCG配置信息至少包括主辅小区PSCell配置。
第一网络节点在接收到终端发送的SCG恢复请求消息后,可以向终端发送所述SCG恢复请求消息的响应消息,用于指示是否允许终端恢复SCG。若所述终端的SCG通过在所述RACH资源上发起的RACH过程恢复,则对于4步RACH过程,所述响应消息可以承载于4步RACH过程的Msg4中;对于2步RACH过程,所述响应消息可以承载于2步RACH过程的MsgB中。若所述终端的SCG通过在所述SR资源上发起的SR过程恢复,则所述响应消息可以承载于SR过程的SR请求响应消息中。
在实际应用中,所述第一网络节点发送的响应消息可以指示允许所述终端恢复SCG,也可以拒绝所述终端恢复SCG,具体可根据实际情况决定,本申请实施例对此不做限定。
在本可选实施方式中,所述响应消息携带SCG配置信息,说明所述第一网络节点发送的响应消息可以指示允许所述终端恢复SCG。应理解的是,若所述第一网络节点拒绝所述终端恢复SCG,所述响应消息可以不包括SCG配置信息。
所述SCG配置信息至少包括主辅小区PSCell配置。进一步地,所述SCG 配置信息还可以包括至少一个SCell配置。
具体实现时,所述SCG配置信息中包括的PSCell配置与所述终端挂起的SCG的PSCell配置可以相同,也可以不同。所述SCG配置信息中包括的SCell配置与所述终端挂起的SCG的SCell配置可以相同,也可以不同。
以下以所述SCG配置信息中包括的PSCell配置进行示例说明:
在所述SCG配置信息中包括的PSCell配置与所述终端挂起的SCG的PSCell配置不同的情况下,进一步地,所述SCG配置信息中包括的PSCell配置可以是一个完整的PSCell配置,在此情况下,终端可以直接根据所述SCG配置信息中包括的PSCell配置进行SCG的恢复;所述SCG配置信息中包括的PSCell配置也可以是一个PSCell配置的变化值,在此情况下,终端需要结合据所述SCG配置信息中包括的PSCell配置和所述终端挂起的SCG的PSCell配置,进行SCG的恢复。
应理解的是,上述示例的实施原理同样适用于所述SCG配置信息中的SCell配置,为避免重复,此处不再赘述。

在1)的场景中,第一网络节点在接收到终端发送的SCG恢复完成消息之后,可以通过Xn等接口向所述终端对应的MN转发接收到的所述SCG恢复完成消息,终端可以无需与其对应的MN通信。在2)的场景中,终端可直接向其对应的MN发送SCG恢复完成消息,第一网络节点可以无需与终端对应的MN通信。
需要说明的是,本申请实施例中的第二网络节点和第一网络节点可以为同一网络节点,也可以为不同的网络节点,具体可根据实际情况决定,本申请实施例对此不做限定。
