背景技术
随着移动通信的快速增长和技术的巨大进步，世界将走向一个完全互联互通的网络社会，即任何人或任何东西在任何时间和任何地方都可以获得信息和共享数据。为了增强移动宽带业务需求、海量物联网终端的通信需求，新一代通信技术(5G)将研究用户在双连接以至多连接下的技术增强(RP-181469 New WID on DC and CA enhancements)。
双连接或者多连接，是指工作在连接态的UE与多于一个网络节点建立物理上的建立无线通路，并实现数据传输。其中，包括主控制节点(Master Node，MN)与辅助控制节点(Secondary Node，SN)。MN由一个Gnb/Enb/ng-eNB来执行，由MN控制的服务小区组称为主小区组(Master Cell Group，MCG)。相应地，SN由一个或多个Gnb/Enb/ng-eNB来执行，由SN控制的服务小区组称为辅小区组(Secondary Cell Group，SCG)。
被配置了双连接或者多连接的UE可以通过和MCG以及和SCG进行通信，实现较高的数据速率。然而，相应地，为了维护和两个网络节点之间的通信，UE的功耗也成倍的增加。为了节约UE的功耗，可以在适当的情况下，例如当UE的通信流量较小的情况下，去激活(deactivate)SCG。网络侧还可以根据需要，重新激活一个被去激活的SCG，如何有效地激活SCG使得数据传输得以恢复是需要解决的问题。

以下，对本发明所涉及的具体实施例进行详细说明。另外，如上所述，本发明中的实施例是为了容易理解本发明而进行的示例性说明，并不是对本发明的限定。
【实施例1】
本实施例给出了一种被配置了双连接或者多连接的UE在与MCG以及SCG进行通信的过程中重新激活一个被去激活的SCG的方法，如图1所示，包括：
步骤S101：UE接收SCG激活命令，当UE接收到激活SCG的命令时，UE至少执行下述操作之一或者多：
-恢复(resume)SRB和DRB在SCG的传输，优选地，可以是恢复所有SRB和所有DRB在SCG的传输；
-在该SCG的PSCell上启动一个随机接入过程，或者是启动在PSCell的随机接入；
-如果定时器T310在运行，那么停止定时器T310，其中T310是指UE在PSCell上连续接收到N个失步(out-of-sync)指示时启动的定时器；
-如果定时器T312在运行，那么停止定时器T312，其中，T312是指被配置了定时器的测量ID(measurement identity)，当它的测量报告(measurement report)被触发时启动的定时器；
-恢复或者启动与该SCG相关联的测量(measuement associated with SCG)或者是测量配置(measConfig associated with SCG)，这里的测量是指根据测量配置而执行的测量操作；这样的测量配置可以是包含在UE从SRB3接收到的RRCReconfiguration消息中，或者是包含在UE从SRB1接收的RRCReconfiguration消息中所嵌入的RRCReconfiguration消息；
-释放与该SCG相关联的在去激活状态下的测量配置；
-激活该SCG的SCell，优选地，可以是激活该SCG所属的所有SCell；或者是在SCG的激活命令中指示了属于该SCG的SCell的状态，激活其中状态设置为激活态的SCell；
-激活该SCG的PSCell；
-启动SCG激活定时器，该定时器的时长由网络侧/基站预先配置，当该定时器运行超时或者被停止时，可以认为SCG进入被去激活的状态，或者是认为该SCG被去激活；
-如果SCG去激活定时器在运行，那么停止该去激活定时器，这个去激活定时器是指当SCG进入去激活状态时，或者收到去激 活命令的时候启动的定时器。
【实施例2】
实施例1中提到的“激活该SCG的SCell”以及“激活该SCG的PSCell”都可以被称为激活服务小区。激活服务小区至少包括下述操作：
-激活任意与该服务小区相关的、处于活跃的BWP(带宽片段)。
当一个服务小区被激活时，其特征如下：
-可以在该服务小区上传输SRS(transmit SRS on the SCell)；
-可以为该服务小区进行CSI报告(report CSI for the SCell)；
-如果该服务小区被配置了上行信道，那么可以在该服务小区的上行信道上进行传输(transmit on UL-SCH on the SCell)；
-如果该服务小区被配置了随机接入信道，那么可以在该服务小区上的随机接入信道上进行传输(transmit on RACH on the SCell)；
-在该服务小区上监听PDCCH(monitor the PDCCH on the SCell)；
-监听和该服务小区相关的PDCCH(monitor the PDCCH for the SCell)：
-如果该服务小区被配置了PUCCH，那么可以在该服务小区上PUCCH进行传输(transmit PUCCH on the SCell)。
可以认为具备上述特征的服务小区可以被称为被激活的小区或者是处于激活态的小区。
实施例2可以在实施例1进行了激活SCell或者激活PSCell的操作的基础上执行。
【实施例3】
实施例1中提到的“激活SCG的PSCell”的另外一种实现方法可以是对该PSCell的BWP进行切换，将当前处于休眠的BWP(Dormant BWP)切换到工作的或者是活跃的BWP(Active BWP)上。
例如，在该PSCell上，接收到SCG激活命令之前，UE工作的BWP是一个休眠的BWP，其BWP ID为BWP-1；当接收到SCG激活命令的时候，将UE在该PSCell上工作的BWP切换到BWP ID为BWP-2的 BWP上。这个BWP-2属于活跃的BWP(Active BWP)或者是一个非休眠的BWP(Non Dormant BWP)。
所述的Dormant BWP是指该BWP配置中不包含PDCCH配置，或者是不包含有效的PDCCH配置，即PDCCH配置缺省(absent)。由于这些PDCCH配置用于PDCCH的监听，因此当休眠BWP不包含PDCCH配置时，UE在休眠BWP上不需要监听相应的PDCCH。相应地，活跃的BWP是指该BWP配置中包含了PDCCH配置，或者是有效的PDCCH配置，用于PDCCH的监听。
优选地，这个BWP-2是一个预先配置的、默认的BWP(default BWP)。当UE接收到SCG激活命令时，在该SCG的PSCell上，UE总是将BWP从休眠BWP切换到该default BWP上。
实施例3可以在实施例1进行了激活PSCell的操作的基础上执行。
【实施例4】
在实施例1-3中提到的SCG激活命令可以有以下三种实施方式：
方式一
SCG激活命令是一个RRC重配置消息(RRC reconfiguration Message)，在该重配置消息中携带了指示激活SCG的信息。例如，在该重配置消息中，携带信元(Information Element)，该信元指示了激活SCG的信息。例如，设置一个SCG状态信元，当该信元取值为真时，或者取值为1时，指示UE激活对应于该信元的SCG。
还可以采用结合的手段，例如，在RRC重配置消息中设置一个SCG状态信元。当在RRC重配置消息中SCG状态信元的取值为真时，或者取值为1时，以及在同一RRC重配置消息中还携带了其他的信元，例如，执行同步的重配置(reconfiguration with sync)的IE时，当两个信元同时出现时，表示指示UE激活相应的SCG。
当UE接收到具有上述特征的RRC重配置消息时，执行前面实施例1-3中所述的激活操作。
方式二
SCG激活命令还可以是一个MAC CE，在该MAC CE中携带了指示激活SCG的信息，例如SCG激活MAC CE。当UE接收到该MAC CE 时，UE向上层，例如RRC层，指示SCG被激活，或是属于该SCG的PSCell被激活。RRC层基于该指示执行前面实施例1-3中所述的激活操作。可选的，在该MAC CE中携带了PSCell或者是属于该SCG的SCell的信息。
例如在该MAC CE中，设置bitmap，每一位分别对应着PSCell或者是SCell。当对应PSCell的比特位对应的取值为1，表示激活PSCell，或者表示激活SCG；当对应SCell的比特位对应的取值为1，表示激活SCell。
特别地，在该MAC CE中还可以重新指示PSCell。例如，在去激活态时PSCell的小区序号/小区ID为X，那么在该MAC CE中可以指示一个小区序号/小区ID为Y的小区作为PSCell，那么在执行激活该SCG的操作时，PSCell不再是之前的小区X，而是小区Y。
这样的SCG激活MAC CE可以是显示地激活或者隐式地激活SCG。
显示地激活
可以设计一个SCG激活MAC CE，在该MAC CE中携带指示，该指示指示UE激活当前配置的SCG。特别地，如果被配置了多个SCG，在该MAC CE中还需要携带SCG的序号。
当UE接收到SCG激活MAC CE，需要向上层指示SCG被激活的信息，这里的上层主要是指RRC层。
RRC层基于该指示，针对被激活的SCG，执行前文中实施例1-3中的任一操作。
隐式地激活
可以设计一个服务小区激活MAC CE，当在该MAC CE中指示激活SCG的PSCell时，UE可以认为接收到了激活SCG的命令。这里通过激活SCG的PSCell来隐式地指示激活SCG。
当UE接收到服务小区激活MAC CE，并且该MAC CE中指示了激活SCG的PSCell时，需要向上层指示SCG被激活的信息，或者是指示SCG PSCell被激活的信息。这里的上层主要是指RRC层。
RRC层基于该指示，针对被激活的SCG，执行前文中实施例1-3中的任一操作。
方式三
SCG激活命令还可以是携带在下行控制信息(Downlink Control Information DCI)中，在该DCI中携带了指示激活SCG的信息。例如，在该DCI中携带一个field，例如SCG状态field，当出现该field时，或者时该field的取值被设置为一个特定值，例如取值为1时，表示激活该SCG。
类似地这样的DCI可以是显示地激活或者隐式地激活SCG。
可以设计一个DCI格式(DCI format)，在该DCI format中携带域(field)，该域或者域值指示激活SCG的PSCell。
当UE接收到携带该DCI format的PDCCH时，可以激活该PSCell，以及认为接收到了激活SCG的命令。由于PDCCH的接收是在物理层处理的，因此当接收到该PDCCH时，需要向上层指示SCG被激活的信息，或者是指示SCG PSCell被激活的信息。
上层基于该指示，针对被激活的SCG，执行前文中实施例1-3中的任一操作。
【实施例5】
在实施例4的基础上，当UE接收到了SCG激活命令时，需要向网络侧/基站发送确定信息或者是响应信息，表示接收到了SCG激活命令。
对应于实施例4中的三种实施方式，该响应信息也可以有三种方式
方式一
UE在接收到携带有SCG激活命令或者是指示SCG激活的RRC重配置消息后，UE生成RRC重配置完成消息，并递交下层进行发送。这条消息作为激活命令的响应消息发送给基站，表示接收到了SCG激活命令。
方式二
UE接收到携带有SCG激活命令或者是指示SCG激活的SCG激活MAC CE时，触发一个SCG激活确认(SCG activation confirmation)，以及在存在一个被触发的SCG激活确认的情况下，当UE获得可用的、用于新传的上行资源时，指示复用和组装实体(Multiplexing and Assembly procedure)生成SCG激活确认MAC CE，用于发送。在生成SCG激活确认MAC CE之后，可以取消被激活的SCG激活确认.
方式三
UE接收到携带有SCG激活命令或者是指示SCG激活的DCI时，在预先配置的PUCCH资源上发送表示确认的信息，例如positive acknowledge，或者是ACK。
【实施例6】
在实施例5中提到当UE接收到了SCG激活命令时，需要向网络侧/基站发送确定信息或者是响应信息。这个响应消息的发送时机可以是在接收到SCG激活命令时发送，还可以是在UE成功激活了SCG时发送。
例如当UE接收到SCG激活命令时，可以启动在PSCell的随机接入过程。当该随机接入过程成功完成时，可以认为SCG被成功激活，那么UE可以在该随机接入成功完成之后发送上述响应消息。
【实施例7】
在实施例1-6中提到UE接收到SCG激活命令时可以恢复在SCG的传输。这个恢复操作的时刻可以是在UE接收到SCG激活命令时(之后)执行，还可以是在UE成功激活了SCG时(之后)执行。
例如当UE接收到SCG激活命令时，可以启动在PSCell的随机接入过程。当该随机接入过程成功完成时，可以认为SCG被成功激活，那么UE可以恢复在SCG的传输。
【实施例8】
在一种情况下，当SCG激活没有成功，那么UE可以启动SCG FAILURE REPORT过程，在该过程中向网络侧发送SCG failure Information message。在该消息中，可以携带发生failure的原因值是SCG激活失败。
这里如何判断SCG激活成功还是失败可以有下述方法：
方法一，如前所述，UE接收到SCG激活命令时，可以启动在PSCell的随机接入过程。当该随机接入过程成功完成时，可以认为SCG被成功激活；如果该随机接入过程没有成功完成，那么可以认为SCG激活失败。例如，当UE接收到一个RA problem，如果该RA是由激活SCG/PSCell 被触发的，那么可以判定SCG激活失败。
方法二，当UE接收到SCG激活命令时，UE可以启动一个SCG激活定时器，当该定时器运行超时时，可以认为SCG激活失败；当SCG激活成功时，例如随机接入过程成功完成，那么可以停止该定时器。在这种情况下，可以在SCG failure Information message指示发生failure的原因值是该定时器运行超时，由于该定时器是在执行SCG激活时启动的，进而网络侧可以判定SCG激活发生了失败。
