Description
本公开涉及通信技术领域,尤其涉及一种传输、监测辅载波配置信息的方法、装置、基站及终端。
随着移动宽带业务的普及,功耗问题一直是终端如智能手机制造商面对的挑战。经过对终端的功耗研究发现:对于PDCCH的监测所消耗的功率占终端总消耗功率的比例超过40%。这是因为针对一个传输单位比如一个子帧,终端在监测PDCCH(Physical Downlink Control Channel,物理下行控制信道)的过程中,盲检次数多达44次;然而大多数情况下,所监测传输单元中并没有属于该终端的数据传输,导致终端因监测PDCCH浪费大量功耗。尤其是在CA(Carrier Aggregation,载波聚合)/DC(Dual Connectivity,双连接)应用场景中,终端需要在多个载波上进行PDCCH监测,将导致更多的功耗浪费。
相关技术为了适应不同的业务类型,并减少PDCCH的功率开销,引入了辅载波激活/去激活机制。即当用户(User Equipment,UE)的业务量较大或者对速率要求较高时,基站会通过激活(Activate)机制为用户添加载波资源,即SCC(Secondary Component Carrier辅载波)资源。另外一方面,当用户的业务量较小或者对速率要求较低时,基站可以通过去激活(Deactivate)机制关闭用户监测的某个辅载波,以减少功率消耗。
然而,相关技术中SCC的激活/去激活配置信息都是由MAC(Media Access Control,媒体介入控制)层信令传输的,由于需要经过物理层,其传输和解析过程需要较长时间,无法满足5G NR系统对资源配置的动态性和灵活性要求。

这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
在本公开使用的术语是仅仅出于描述特定实施例的目的,而非旨在限制本公开。在本公开和所附权利要求书中所使用的单数形式的“一种”、“所述”和“该”也旨在包括多数形式,除非上下文清楚地表示其他含义。还应当理解,本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。
应当理解,尽管在本公开可能采用术语第一、第二、第三等来描述各种信息,但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如,在不脱离本公开范围的情况下,第一信息也可以被称为第二信息,类似地,第二信息也可以被称为第一信息。取决于语境,如在此所使用的词语“如果”可以被解释成为“在……时”或“当……时”或“响应于确定”。
本公开涉及的执行主体包括:基站和终端,其中,基站可以是设置有大规模天线阵列的基站、子基站等。终端可以是用户设备(User Equipment,UE)、用户节点、移动终端或平板电脑等。在具体实现过程中,基站和终端各自独立,同时又相互联系,共同实现本公开提供的技术方案。
基于此,本公开提供了一种传输辅载波配置信息的方法,应用于5G NR(New Radio,新空口)网络的预设应用场景中,该应用场景中,基站除了可以在主载波PCC(Primary component carrier)上调度UE,还可以为UE配置一个或多个辅载波SCC(Secondary component carrier,辅载波),以便在上述辅载波SCC上调度UE,比如CA(Carrier Aggregation,载波聚合)/DC(Dual Connectivity,双连接)应用场景中。
参见图1根据一示例性实施例示出的一种传输辅载波配置信息的方法流程图,应用于基站中,所述方法可以包括以下步骤:
在步骤11中,确定辅载波SCC配置信息,所述SCC配置信息用于指示去激活或激活所述辅载波;
本公开中,基站可以按照预置规则在预设触发条件下针对UE的辅载波SCC确定去激活/激活指示信息。
以终端为UE1为例,对于UE1在辅载波SCC上处于去激活状态的情况,当 UE1的业务量较大或者待传输业务对速率要求较高时,基站会针对UE1生成一个SCC激活指示信息,发送给UE1,通过激活机制为UE1添加辅载波资源,以便基站可以同时在主载波PCC和上述辅载波SCC上同时调度UE1,提高该UE1的业务传输量或业务数据的传输效率。
另一方面,对于UE1在SCC上处于激活状态的情况,当UE1的业务量较小或者待传输业务对速率要求较低时,基站可以针对UE1生成一个SCC去激活指示信息,发送给UE1。由于UE1在某个辅载波上处于激活状态时,需要在此载波上不断监测PDCCH信息以进行正常的业务调度,导致UE的功耗增加,通过去激活机制关闭UE1监测的某个载波,可以减少功率消耗。
对于UE的一个SCC而言,上述SCC配置信息包括:SCC去激活指示信息,或者,SCC激活指示信息。
若基站为UE配置有多个SCC,上述SCC配置信息可以包括针对一个或多个SCC的去激活/激活指示信息。
在步骤12中,根据所述SCC配置信息生成目标物理层信号;
本公开中,基站在确定了SCC配置信息之后,可以直接将该SCC配置信息编码成物理层信号,以便后续直接通过物理层信道进行传输。
相关技术如LTE(Long Term Evoluttion,长期演进)系统中,由于物理层信令资源有限,又鉴于辅载波激活/去激活机制的实现需要大量的控制信令,一般通过上层信令如MAC信令传输上述SCC激活/去激活指示信息。
假设相关技术中,通过MAC信令传输上述SCC激活/去激活指示信息,则其传输过程为:由于MAC信令属于数据链路层信令,首先将包含SCC激活/去激活指示信息的MAC信令由数据链路层映射至物理层,包装成满足物理层数据格式要求的消息才能传输给UE。到达UE后,UE侧的物理层首先对消息进行验证,再映射到数据链路层进行解析。其中包括了数据链路层与物理层之间数据格式的转换以及信息验证过程所花费的时间,实践证明上述时间约为20ms,导致SCC配置信息的传输时延过长。若5G NR系统仍采用相关技术中的SCC配置信息传输方式,将无法满足5G NR系统对资源配置的灵活性要求。
本公开利用5G NR系统丰富的物理层信令资源,可以直接将SCC配置信息编码成物理层信号进行传输,从而有效缩短上述SCC配置信息的传输时延,进而提高资源配置的灵活性。
关于物理层资源对SCC配置信息的承载,根据SCC配置信息的类型不同,用 于承载上述SCC配置信息的物理层资源也略有不同。
对于SCC去激活指示信息,可以通过PCC或SCC的专用物理层信道资源承载,或者,利用对应SCC上的PDCCH资源承载。
对于SCC激活指示信息,可以通过PCC或SCC的专用物理层信道资源承载。
针对一个SCC的去激活/激活指示信息的传输,上述步骤12的实施可以包括:
实施方式一、本公开中,基站可以将SCC配置信息加载于预设载波的目标物理层信道中,生成目标物理层信号。其中,仍以UE1为例,上述预设载波可以是UE1的主载波PCC,也可以是配置给UE1的辅载波。
参见图2根据一示例性实施例示出的另一种传输辅载波配置信息的方法流程图,上述步骤12可以包括:
在步骤121中,确定用于承载所述SCC配置信息的、预设载波的目标物理层信道;
本公开一实施例中,基站可以按照协议规定,确定用于承载SCC配置信息的目标物理层信道,该目标物理层信道可以是传输上述SCC配置信息的专用信道。上述目标物理层信道可以是基站按照协议规定,在UE的主载波中确定的指定物理层信道;也可以是基站按照协议规定,在UE的辅载波中确定的指定物理层信道。
在本公开另一实施例中,基站也可以为UE配置目标物理层信道。
参见图3根据一示例性实施例示出的另一种传输辅载波配置信息的方法流程图,上述步骤121可以包括:
在步骤1211中,基于所述预设载波配置所述目标物理层信道,生成所述目标物理层信道的配置信息,所述配置信息至少包括:所述目标物理层信道的频率范围;
本公开中,基站可以基于UE的主载波或者辅载波,自主配置用于承载上述SCC配置信息的目标物理层信道,获得目标物理层信道的配置信息,以便后序将上述目标物理层信道的配置信息告知UE。其中,上述目标物理层信道的配置信息至少包括:目标物理层信道的频率范围;还可以包括:所述SCC配置信息的潜在传输时机,和/或,承载所述SCC配置信息的预设资源的位置信息。
其中,上述目标物理层信道的频率范围用于告知UE目标物理层信道的位置,以便UE精确定位目标物理层信道,进而从该目标物理层信道上监测属于自己的SCC配置信息。
上述承载所述SCC配置信息的预设资源的位置信息,用于告知UE在目标物理层信道什么位置的时频资源中可能承载有SCC配置信息,以便UE可以精确定位目标 资源,缩小监测范围,提高SCC配置信息的检测效率,进而节约UE功耗。
所述SCC配置信息的潜在传输时机,用于告知UE在什么时机监测SCC配置信息,避免UE一直处于监测状态而浪费功耗。
本公开一实施例中,若基站按照预设传输周期在目标物理层信道上向UE发送SCC配置信息。则上述SCC配置信息的潜在传输时机,可以是基站明确告知UE的预设传输周期,比如10ms。对应的,UE在获取上述潜在传输时机后,可以参照上述预设传输周期进行SCC配置信息的检测,如上示例,每10ms检测一次。
在公开另一实施例中,上述SCC配置信息的潜在传输时机,还可以是表示基站可能发送SCC配置信息的预置条件信息。
其中,若上述SCC配置信息为SCC去激活指示信息,在一实施例中,上述预置条件信息可以是:UE在预设SCC的预设数量的连续传输周期内未监测到属于自己的PDCCH信息。
在步骤1212中,将所述目标物理层信道的配置信息发送给所述终端。
本公开中,基站可以通过高层信令将目标物理层信道的配置信息发送给UE。其中,上述高层信令可以是RRC(Radio Resource Control,无线资源控制)信令、MAC(Medium Access Control,媒介访问控制)CE(Control Element,控制单元)信令等。
在步骤122中,将所述SCC配置信息加载于所述目标物理层信道的预设资源中。
根据基站为UE配置的辅载波数量,以及在哪个载波上配置上述目标物理层信道不同,上述步骤122的实施可以包括以下两种情况:
第一种情况,对应基站为UE配置有一个SCC,即需要传输的SCC配置信息的数量为一个,或者,基站在SCC上配置目标物理层信道的情况。此种情况下,针对一个UE,基站配置的目标物理层信道用于传输一个SCC的去激活/激活指示信息。
参见图4根据一示例性实施例示出的另一种传输辅载波配置信息的方法流程图,上述步骤122可以包括:
在步骤1221中,根据所述SCC配置信息确定对应的目标状态指示值;
如上所述,对于一个UE,基站为其确定的SCC配置信息可以是SCC去激活指示信息,或者,SCC激活指示信息。
本公开中,系统可以预置有预设状态指示值,该预设状态指示值可以是协议规定的、用于分别表示SCC去激活指示信息和SCC激活指示信息的数值。该数值可以是预设序列值,也可以是预设比特指示值。
假设上述预设状态指示值为预设序列值,本公开中,基站中可以预置有第一预设列表,该第一预设列表包括:不同SCC配置信息与预设序列值的对应关系。基站可以根据上述步骤11确定的SCC配置信息查询第一预设列表,确定SCC配置信息对应的目标序列值。
示例性的,上述第一预设列表可以如表一所示:
预设序列值 | SCC配置信息 |
第一序列值 | SCC去激活指示信息 |
第二序列值 | SCC激活指示信息 |
表一
假设基站根据步骤11确定的SCC配置信息为SCC去激活指示信息,查询上述表一可知,目标序列值为第一序列值。
同理,若上述预设状态指示值为预设比特指示值,则基站中可以预置有第二预设列表。该第二预设列表包括:不同SCC配置信息与预设比特指示值之间的对应关系。基站可以根据上述步骤11确定的SCC配置信息查询第二预设列表,确定SCC配置信息对应的目标比特指示值。
示例性的,上述第二预设列表可以如表二所示:
SCC配置信息 | 预设比特指示值 |
SCC去激活指示信息 | 0 |
SCC激活指示信息 | 1 |
表二
如上示例,若步骤11确定的SCC配置信息为SCC去激活指示信息,查询上述表二可知,目标比特指示值为0。
此处需要说明的是,在本公开另一实施例中,系统也可以采用比特值0代表SCC激活指示信息;比特值1代表SCC去激活指示信息,本公开对此不做限定。
在步骤1222中,将所述目标状态指示值映射于所述目标物理层信道的预设资源中。
基站在确定了目标物理层信道、SCC配置信息对应的目标状态指示值之后,可以按照协议规定或者上述步骤1211中基站配置的、预设资源的位置信息,将上述目标状态指示值加载于目标物理层信道的预设资源中,生成目标物理层信号,准备发送给终端。其中,上述目标物理层信道可以是主载波的预设物理层信道,也可以是辅载波的预设物理层信道。
第二种情况,对应基站为一个终端配置有多个辅载波SCC,并且在UE的主载波PCC上配置有目标物理层信道,该目标物理层信道用于传输各个SCC的去激活/激活指示信息。
参见图5根据一示例性实施例示出的另一种传输辅载波配置信息的方法流程图,上述步骤122可以包括:
在步骤1223中,根据每个所述辅载波的SCC配置信息,生成用于指示每个所述辅载波去激活/激活状态的位图信息;
示例性的,假设基站为UE配置有6个可用的辅载波,分别表示为:SCC1、SCC2、SCC3、SCC4、SCC5、SCC6。假设基站根据UE当前业务调度状态确定的SCC配置信息包括:去激活SCC1、SCC3、SCC4;激活CC2、SCC5、SCC6。则基站根据上述各SCC的配置信息生成的位图bitmap信息可以参见图6所示,采用预设6个bit承载上述SCC配置信息,每个bit位对应一个SCC,如上示例,当该bit被置为0,代表去激活该SCC的指示信息,反之,若当该bit被置为1,代表激活该SCC的指示信息。
在步骤1224中,将所述位图信息映射于所述主载波的所述目标物理层信道的预设资源中。
在确定了上述位图信息之后,可以将该位图信息映射至主载波目标物理层信道的预设资源中,准备发送给终端。
上述实施方式一,适用于任何一种SCC配置信息对应的目标物理层信号的生成过程。
通过系统约定的或者基站实时配置的目标物理层信道,专门传输SCC配置信息,可以提高SCC配置信息的传输效率,进而提高动态配置资源的灵活性,从而满足不同业务需求,提高5G NR网络的用户体验。
本公开中,若步骤11确定的SCC配置信息为:SCC去激活指示信息,则可以将上述SCC去激活指示信息加载于该SCC的PDCCH信息中,详见实施方式二。
实施方式二,将所述SCC去激活指示信息加载于所述SCC上传输的、所述终端的PDCCH信息中,生成所述目标物理层信号。
本公开中,基站可以采用以下任一方式,将一个SCC的去激活指示信息加载于PDCCH信息中,生成目标物理层信号。
方式一、将所述SCC去激活指示信息加载于目标资源的预设资源位中,其中,所述目标资源用于承载所述终端的下行控制信息DCI;
根据相关知识,一个SCC的PDCCH信道上可以同时传输多个UE的DCI (Downlink Control Information,下行控制信息)。对于一个目标UE如UE1,基站可以确定承载UE1的DCI信息的目标资源区域,并按照预置策略将上述目标资源区域的预设资源位用来承载上述SCC去激活指示信息。
方式二、采用预设RNTI(Radio Network Tempory Identity,无线网络临时标识)序列对所述终端的DCI信息中的循环冗余校验CRC码进行加扰,生成标识所述SCC去激活指示信息的目标PDCCH信息;
本公开实施例中,基站可以采用预设RNTI序列值对终端的DCI中的CRC(Cyclic Redundancy Check,循环冗余校验)码进行加扰,以表示不同的SCC配置信息。
其中,预设RNTI序列值与不同SCC配置信息的对应关系,可以如表三所示:
SCC配置信息 | 预设RNTI序列值 |
SCC去激活指示信息 | 第一RNTI值 |
SCC激活指示信息 | 第二RNTI值 |
表三
如上示例,若步骤11确定的SCC配置信息为SCC去激活指示信息,查询上述表三可知,对应第一RNTI值。
则基站在生成UE1的DCI信息时,采用上述第一RNTI值对DCI的CRC加扰,生成携带有SCC去激活指示信息的DCI信息,即UE1的目标PDCCH信息。
相应的,UE1在SCC的PDCCH信道检测DCI信息时,若采用第一RNTI序列值解扰成功,可以获知该DCI信息中携带了SCC去激活指示信息。
本公开实施例中,通过加扰在DCI循环冗余校验CRC码上的无线网络临时标识RNTI值指示对当前SCC的去激活指示信息,可以节约用于承载SCC配置信息的无线资源。
方式三,利用所述终端的PDCCH信息在控制区域中的传输位置,标识所述SCC去激活指示信息。
针对每一个传输单元比如时隙slot,基站可以按照预置规则计算目标CCE的可能传输位置,其中,目标CCE为可以承载终端DCI信息的控制信道单元。
本公开中,基站可以将一个UE的所有目标CCE(Control Channel Element,控制信道单元)的可能传输位置进行划分,分为第一预设传输位置和第二预设传输位置;并定义第一预设传输位置或第二预设传输位置与SCC去激活指示信息的关联关系。比如,将SCC去激活指示信息与第一预设传输位置的目标CCE关联。
基站在传输目标UE的DCI信息时,若步骤11确定的SCC配置信息为SCC去激 活指示信息,则将UE1的DCI信息加载于第一预设传输位置的目标CCE中进行传输。
相应的,目标UE在进行盲检时,若在第一预设位置的CCE中检测到属于自己的DCI,则确定监测到了该SCC的去激活指示信息。反之,若目标UE在第二预设位置的CCE中检测到了属于自身的DCI,则确定没有监测到该SCC的去激活指示信息。
仍假设目标UE是UE1,假设一个传输单元的控制区域包括36个CCE,基站按照预置规则,计算出UE1的目标CCE包括:1、3、5、7、9、11号CCE。
假设系统约定前半部分的目标CCE属于第一预设位置的CCE,即第1、3、5号CCE,并关联SCC去激活指示信息。
如上示例,若步骤11确定的SCC配置信息为SCC去激活指示信息,则可以将UE1的DCI信息加载于第1、3、5号CCE中的一个或多个CCE中,在SCC的PDCCH信道上传输。
反之,若基站未确定SCC去激活指示信息,则将UE1的DCI信息加载于第7、9、11号CCE中的一个或多个CCE中,在SCC的PDCCH信道上传输,参见图7根据一示例性实施例示出的另一种传输SCC配置信息的场景示意图。
本公开实施例中,通过设置DCI信息的承载资源位置隐形指示SCC去激活指示信息,也可以节约承载SCC配置信息的无线资源。
上述实施方式二,适用于终端在一个SCC上处于激活状态时,通过PDCCH信息携带该SCC的去激活指示信息,可以避免为SCC配置信息设置独立的物理传输信道,进而可以节约无线资源。
在步骤13中,通过所述目标物理层信号将所述SCC配置信息发送给终端,以使所述终端根据所述SCC配置信息确定是否在所述SCC上监测物理下行控制信道PDCCH信息。
本公开中,基站可以直接通过物理层信号承载辅载波SCC的去激活/激活指示信息,节省了由高层配置上述SCC激活/去激活信息时从高层向低层映射所花费的时间,以及数据格式转换时间,有效提高了SCC配置信息的传输效率,使得UE可以快速解析SCC配置信息,并根据上述SCC配置信息及时确定是否在相应SCC上监测属于自己的PDCCH信息,对于SCC去激活指示的情况,可以及时告知UE适时停止在SCC上监测PDCCH信息,从而节约UE功耗。
相应的,本公开还提供了一种监测辅载波配置信息的方法,应用于终端中。参见图8根据一示例性实施例示出的一种监测辅载波配置信息的方法流程图,所述方法可以包括以下步骤:
在步骤21中,确定用于承载辅载波SCC配置信息的目标物理层信号的传输配置信息;
其中,所述目标物理层信号的传输配置信息用于告知终端如何获取SCC配置信息。所述SCC配置信息用于指示去激活或激活所述辅载波,可以包括:SCC去激活指示信息或SCC激活指示信息。
本公开中,UE可以采用以下至少两种方式确定上述目标物理层信号的传输配置信息:
第一种方式,按照系统协议约定,确定上述目标物理层信号的传输配置信息。该目标物理层信号的传输配置信息可以是设备制造商或移动运营商预置在终端硬件中的配置信息。或者,在终端接入小区网络后,从基站广播的系统消息中获取到的、关于SCC配置信息的传输配置信息。
第二种方式,对应基站可以自主配置的情况,终端可以接收基站自主确定的、目标物理层信号的传输配置信息。
对应上述步骤12的实施方式一,上述目标物理层信号的传输配置信息可以是目标物理层信道的资源配置信息,至少包括:目标物理层信道的频率范围,还可以包括:承载所述SCC配置信息的预设资源的位置信息、所述SCC配置信息的潜在传输时机。
对应上述步骤12的实施方式二,上述目标物理层信号的传输配置信息也可以是用于指示PDCCH信息如何携带SCC去激活指示信息。
在步骤22中,根据所述目标物理层信号的传输配置信息和当前用户状态,从所述目标物理层信号中监测属于自身的SCC配置信息;
根据承载SCC配置信息的物理层资源的不同,本公开中步骤22的实施方式可以包括三种情况:
情况一、在所述SCC的预设物理层信道资源中监测属于自身的SCC配置信息;
本公开中,当上述资源配置信息指示UE在SCC的预设物理层信道中监测属于自身的SCC配置信息时,UE可以根据已知的、SCC配置信息传输时机,从一个SCC的预设物理层信道上监测SCC去激活/激活指示信息。
情况二、在主载波的预设物理层信道资源中监测属于自身的SCC配置信息;
本公开中,当上述资源配置信息指示UE在PCC的预设物理层信道中监测属于自身的SCC配置信息时,若基站为UE配置有一个SCC,上述SCC配置信息的监测过程与上述情况一类似;若基站为UE配置有多个SCC,则UE根据已知的、SCC配 置信息传输时机,根据当前SCC对应的位图信息确定针对当前SCC的SCC配置信息。
情况三、从所述SCC的PDCCH资源中监测属于自身的SCC去激活指示信息。
若基站告知UE,当其在SCC上处于激活状态时,从属于其自身的PDCCH信息中监测该SCC的去激活指示信息。则UE根据已知的、SCC配置信息传输时机,按照预设方式根据监测到的属于自身的PDCCH信息,解析PDCCH信息中是否携带有该SCC的去激活指示信息。
例如,根据目标区域的预设资源位的指示值确定SCC去激活指示信息,上述目标资源区域为承载UE的DCI信息的资源区域。或者,利用预设RNTI序列值解扰DCI中的CRC确定SCC去激活指示信息。或者,根据监测到DCI信息的目标CCE的传输位置确定DCC去激活指示信息。上述SCC去激活指示信息的监测过程与上述步骤12的实施方式二相对应,相互参见即可。
针对预设载波设置有目标物理层信道的情况,根据所述SCC配置信息的潜在传输时机的不同,UE可以采用以下至少两种方式监测SCC配置信息:
方式一、按照所述SCC配置信息的预设传输周期,从所述目标物理层信号中监测属于自身的SCC配置信息。比如,在与系统信号同步的情况下,在目标物理层信道上每10ms监测一次SCC配置信息。
方式二、按照上述预置条件信息,监测SCC配置信息
参见图9根据一示例性实施例示出的另一种监测辅载波配置信息的方法流程图,上述步骤22可以包括:
在步骤221中,当所述终端在所述SCC上处于激活状态时,若在当前传输周期内未监测到属于自身的PDCCH信息,开始记录监测失败次数;
在步骤222中,确定在后序连续多个传输周期内是否监测到属于自身的PDCCH信息;
在步骤223中,若在后序连续多个传输周期内均未监测到属于自身的PDCCH信息,确定所述PDCCH信息监测失败的连续累计次数;
在步骤224中,若所述连续累计次数达到预设阈值,开始监测所述SCC去激活指示信息。
在步骤23中,根据监测到的所述SCC配置信息,确定是否在所述SCC上监测物理下行控制信道PDCCH信息。
当某个SCC处于激活状态时,UE会尝试监测对应此SCC的去激活指示信息,如果监测到此SCC的去激活指示信息,UE在一段时间后停止在此SCC上监测PDCCH 信息,然后该SCC处于去激活状态。另一方面,如果没有监测到对应此SCC的去激活指示信息,UE则继续监测此SCC上的PDCCH信息,此SCC仍处于激活状态。当某个SCC处于去激活状态时,UE则尝试监测此SCC对应的激活指示信息,一旦检测到该SCC的激活指示信息,则该SCC在一段时间内将被激活,UE将在此SCC上开始监测PDCCH信息。
