为便于理解本申请实施例的技术方案，以下对本申请实施例相关的技术方案进行说明。
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，为此第三代合作伙伴计划(3 rd Generation Partnership Project，3GPP)国际标准组织开始研发5G。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-Reliable Low-Latency Communications，URLLC)、大规模机器类通信(massive Machine-Type  Communications，mMTC)。
一方面，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，例如室内，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。同时为了保护移动运营商前期在LTE投资，提出了LTE和NR之间紧耦合(tight interworking)的工作模式。
为了能够尽快实现5G网络部署和商业应用，3GPP完成第一个5G版本，即EN-DC(LTE-NR Dual Connectivity)。在EN-DC中，LTE基站(eNB)作为主节点(Master Node，MN)，NR基站(gNB或en-gNB)作为辅节点(Secondary Node，SN)，EN-DC的网络部署和组网架构如图2所示，其中，演进的通用无线接入网(Evolved Universal Terrestrial Radio Access Networ，E-UTRAN)代表接入网部分，演进型分组核心网(Evolved Packet Core network，EPC)代表核心网部分，接入网部分由至少一个eNB(图2中示意出两个eNB)和至少一个en-gNB(图2中示意出两个en-gNB)组成，其中，eNB作为MN，en-gNB作为SN，MN和SN均连接到EPC。在R15后期，将支持其他DC模式，即NE-DC，5GC-EN-DC，NR DC。对于EN-DC，接入网络连接的核心网是EPC，而其他DC模式连接的核心网是5GC。
其中，MN主要负责RRC控制功能以及通向CN的控制面，SN可以配置辅助的信令，例如SRB3，主要提供数据传输功能。
在5G中，最大的信道带宽可以是400MHZ(称为宽带载波(wideband carrier))，相比于LTE最大20M带宽来说，宽带载波的带宽很大。如果终端设备保持工作在宽带载波上，则终端设备的功率消耗非常大。所以建议终端设备的射频(Radio Frequency，RF)带宽可以根据终端设备实际的吞吐量来调整。为此，引入BWP的概念，BWP的动机是优化终端设备的功率消耗。例如终端设备的速率很低，可以给终端设备配置小一点的BWP(如图3-1所示)，如果终端设备的速率要求很高，则可以给终端设备配置大一点的BWP(如图3-2所示)。如果终端设备支持高速率，或者工作在载波聚合(Carrier Aggregation，CA)模式下，可以给终端设备配置多个BWP(如图3-3所示)。BWP的另一个目的就是触发一个小区中多个参数集(numerology)共存，如图3-3所示，BWP1对应基础参数集(numerology)1，BWP2对应numerology2。
通过无线资源控制(Radio Resource Control，RRC)专用信令可以给一个终端配置最多4个上行BWP和最多4个下行BWP，但同一时刻只能有一个上行BWP和下行BWP被激活。在RRC专用信令中，可以指示所配置的BWP中第一个激活的BWP。同时在终端处于连接态过程中，也可以通过下行控制信息(Downlink Control Information，DCI)在不同的BWP之间切换。当处于非激活状态的载波，进入激活状态后，第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。每个BWP的配置参数包括：
-子载波间隔(subcarrierSpacing)；
-循环前缀(cyclicPrefix)；
-BWP的第一个物理资源块(Physical Resource Block，PRB)以及连续的PRB个数(locationAndBandwidth)；
-BWP标识(bwp-Id)；
-BWP公共配置参数和专用配置参数(bwp-Common，bwp-Dedicated)。
终端在进行无线链路监控(Radio Link Monitor，RLM)过程中，只在激活的BWP上执行，非激活的BWP不需要操作，而在不同BWP之间进行切换的时候，也不需要重置RLM相关的定时器和计数器。对于RRM测量，无论终端在哪个激活的BWP上收发数据，都不影响RRM测量。对于CQI的测量，终端也只需要在激活的BWP上执行。
当一个载波被去激活，然后通过媒体接入控制控制单元(Media Access Control Control Element，MAC CE)激活了该载波，则初始的第一个激活的BWP为RRC专用信令中配置的第一个激活的BWP。
BWP标识(BWP id)在RRC专用信令中的取值为0到4，BWP标识为0的BWP默认为初始BWP。
在DCI中BWP指示(BWP indicator)为2比特(bit)，如下表1所示。如果配置的BWP个数小于等于3个，则BWP indicator＝1,2,3分别对应BWP id＝1,2,3。如果BWP的个数为4个，则BWP indicator＝0,1,2,3分别对应按照顺序索引配置的BWP。而且网络侧在配置BWP的时候使用连续的BWP id。
Figure PCTCN2019116375-appb-000001
表1
为了满足高速率的需求，5G中也支持CA技术。CA通过联合调度和使用多个成员载波(Component Carrier，CC)上的资源，使得NR系统可以支持更大的带宽，从而能够实现更高的系统峰值速率。根据所聚合载波的在频谱上的连续性可以分为，连续性载波聚合和非连续性载波聚合；根据聚合的载波所在的带宽(band)是否相同，分为带内(Intra-band)载波聚合和带间(inter-band)载波聚合。
在CA中，主载波(Primary Cell Component，PCC)有且只有一个，PCC提供RRC信令连接，非接入层(NAS)功能，安全功能等。物理上行控制信道(Physical Uplink Control Channel，PUCCH)在PCC上且只在PCC上存在。辅载波(Secondary Cell Component，SCC)只提供额外的无线资源。PCC和SCC同称为服务小区，其中，PCC上的小区为主小区(Primary cell，Pcell)，SCC上的小区为Scell。标准上还规定聚合的载波最多支持5个，即聚合后的最大带宽为100MHZ，并且聚合载波属于同一个基站。所有的聚合载波使用相同的小区无线网络临时标识(Cell-Radio Network Temporary Identifier，C-RNTI)，基站实现保证C-RNTI在每个载波所在的小区不发生冲突。由于支持不对称载波聚合和对称载波聚合两种，所以要求聚合的载波一定有下行，可以没有上行。而且对于PCC小区来说一定有本小区的PDCCH和PUCCH，而且只有主载波小区有PUCCH，其他辅载波小区可能有PDCCH。
为了支持终端设备的节能以及快速建立SCG，提出dormancy SCG的概念，dormancy SCG意味着SCG中的所有小区处于休眠状态，处于休眠状态的小区可以称为dormancy小区。终端设备在dormancy小区不监听PDCCH，不执行数据的发送和接收，但是RRM/CSI测量以及波束管理等。所以，如何支持dormancy SCG是个需要明确的问题。为此，提出了本申请实施例的以下技术方案。
图4为本申请实施例提供的状态转换方法的流程示意图一，如图4所示，所述状态转换方法包括以下步骤：
步骤401：主节点接收辅节点发送的第一指示信息，所述第一指示信息用于指示所述辅节点侧的业务不活跃。
本申请实施例的技术方案可以应用但不局限于双连接架构中，例如多连接架构。在双连接架构或多连接架构中，主节点(MN)覆盖的小区集合称为主小区组(MCG)，辅节点(SN)覆盖的小区集合称为SCG。MCG包括一个主小区(PCell)和至少一个辅小区(SCell)。SCG包括一个主辅小区(PScell)和至少一个辅小区(SCell)。
对于辅节点侧的SCG而言，支持休眠状态。本申请实施例将处于休眠状态的SCG称为dormancy SCG，将处于非休眠状态的SCG称为non-dormancy SCG，将处于激活状态的SCG称为激活SCG。可选地，non-dormancy SCG和激活SCG可以指同一状态。
本申请实施例中，1)若所述辅节点在SCG承载上未接收到来自核心网的下行数据，且未接收到来自终端设备的上行数据，则所述辅节点向所述主节点发送所述第一指示信息；或者，2)若所述辅节点在SCG承载上未接收到来自核心网的下行数据，且接收到来自终端设备的针对所述SCG承载的一次或者多次BSR上报为0，则所述辅节点向所述主节点发送所述第一指示信息。其中，所述第一指示信息用于指示所述辅节点侧的业务不活跃。
步骤402：若所述主节点确定没有下行数据转发给所述辅节点和/或没有来自辅节点发送的上行数据，则所述主节点向所述辅节点发送第一确认信息，所述第一确认信息用于触发SCG进入休眠状态。
在一可选实施方式中，所述主节点接收到所述辅节点发送的所述第一指示信息后，启动第一定时器；若所述第一定时器超时之前，所述主节点未接收到来自核心网的需要转发给所述辅节点的下行数据和/或没有来自辅节点发送的上行数据，则所述主节点向所述辅节点发送所述第一确认信息。
本申请实施例中，所述主节点确定没有下行数据转发给所述辅节点和/或没有来自辅节点发送的上行数据，包括：
所述主节点确定所述主节点终结的分流承载上没有下行数据转发给所述辅节点；和/或，
所述主节点确定所述主节点终结的分流承载对应的BSR上报为0。
对于所述辅节点来说，若所述辅节点接收所述主节点发送的第一确认信息，则触发SCG进入休眠状态。
在一可选实施方式中，所述主节点向终端设备发送第二指示信息，所述第二指示信息用于通知所述终端设备SCG进入休眠状态。进一步，可选地，所述第二指示信息通过所述主节点侧的RRC信令或者MAC CE或者PDCCH携带。
以下结合具体示例对本申请实施例的技术方案进行举例说明。
示例一
参照图5，本示例的状态转换方法包括以下流程：
1、SN检测到业务不活跃。
这里，SN在SCG RLC承载上如果接收不到来自CN的下行数据，同时也接收不到来自UE的上行数据，或者对于上行该SCG RLC承载对应的BSR上报为0(或者持续几次BSR上报为0)，则SN向MN通知SN侧的业务不活跃(见如下步骤2)。
2、SN向MN通知SN侧的业务不活跃。
这里，SN向MN通知SN侧的业务不活跃也可以替换成SN向MN通知SN侧的休眠条件满足(SN inform MN the dormancy condition is met)。
具体地，MN收到SN发送的SN侧的业务不活跃的指示后，判断MN终结的分流承载(split bear)上没有下行数据需要转发给SN，则MN可以判决让SCG进入休眠状态。可选地，在这个过程中MN在接收到SN侧的业务不活跃的指示后，启动第一定时器，如果第一定时器超时前，没有接收到来自CN的MN终结的split bear上的下行数据需要转发给SN，则MN可以判决让SCG进入休眠状态。
3、MN向SN通知SCG进入休眠状态。
这里，MN向SN通知SCG进入休眠状态也可以理解为MN向SN发送第一确认信息，所述第一确认信息用于触发SCG进入休眠状态，应理解，第一确认信息用于确认休眠决定(confirm the dormancy decision)。
具体地，MN通过Xn/X2接口信令通知SN SCG进入休眠状态。
4、MN向UE通知SCG进入休眠状态。
具体地，MN通过MN侧的RRC信令或者MN MAC CE或者MN PDCCH通知UE SCG进入休眠状态。
