具体实施方式
下面将结合本发明实施例中的附图，对本发明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做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。
本发明的技术方案，可以应用于各种通信***，例如：GSM，码分多址(CDMA，Code Division Multiple Access)***，宽带码分多址(WCDMA，Wideband Code Division Multiple Access Wireless)，通用分组无线业务(GPRS，General Packet Radio Service)，长期演进(LTE，Long Term Evolution)等。
用户设备(UE，User Equipment)，也可称之为移动终端(Mobile Terminal)、移动用户设备等，可以经无线接入网(例如，RAN，Radio Access Network)与一个或多个核心网进行通信，用户设备可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(BTS，Base Transceiver Station)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(eNB或e-NodeB，evolutional Node B)，本发明并不限定，但为描述方便，下述实施例以Node B为例进行说明。
为了更加清楚地理解本发明，下面将结合图1对本发明所提到的MAC PDU数据包的格式进行简单介绍。
如图1所示，一个MAC PDU包含MAC头(header)和MAC净荷(payload)。其中，MAC payload包括0个或至少一个MAC CE(Control element，控制单元)，0个或至少一个MAC业务数据单元(Service Data Unit，SDU)和可选的padding(填充)。
MAC header包含多个子头(sub-header)，每个子头中包括R/R/E/LCID字段，其中，R代表保留字段，E代表是否当前的子头是该MAC PDU里的最后一个子头，LCID为逻辑信道标识(logic Channel ID)
每个sub-header按顺序对应MAC净荷中的单元(MAC CE，MAC SDU或padding)，即第一sub-header对应第一个单元，第二个sub-header对应第二个单元，依次类推。
sub-header中的LCID中的取值可以表征该sub-header所对应的单元的类型。例如，当下行MAC PDU数据包里的sub-header里的LCID取值为11011，则表示MAC净荷中对应的位置是激活去激活MAC CE；当上行MAC PDU数据包里的sub-header里的LCID取值为11001，则表示MAC净 荷中对应的位置是一个扩展Extended功率余量上报(Power Headroom Report，PHR)MAC CE；当上行MAC PDU数据包里的sub-header里的LCID取值为11000，则表示MAC净荷中对应的位置是一个双连接Dual Connectivity PHR MAC CE。
现有协议中的信令结构最多支持8个小区聚合(1个主小区和7个辅小区)，即图1中的MAC CE的结构如下所示：
Figure PCTCN2015079034-appb-000001
但是随着***的频谱效率和用户吞吐量进一步提升，更多的小区(例如，32个)需要被聚合，如何在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量是一项亟待解决的问题。
为此，本发明提供以下技术方案，可以解决该问题，以下将结合图2至图xx进行详细说明。
图2是根据本发明实施例的通信方法100的示意性流程图。如图2所示，该方法100包括：
110，第一通信设备生成MAC PDU数据包，该MAC PDU数据包包括至少一个第一类型的MAC CE，第一类型的每个MAC CE用于携带至少一个辅小区的信息，其中，该第一通信设备根据具有该第一类型的MAC CE对应的辅小区确定具有该第一类型的MAC CE在该MAC PDU数据包中的位置；
120，该第一通信设备向第二通信设备发送该MAC PDU数据包，用于该第二通信设备获取具有该第一类型的MAC CE并根据具有该第一类型的MAC CE在该MAC PDU数据包中的位置确定具有该第一类型的MAC CE对应的辅小区以获取辅小区的信息。
具体地说，第一通信设备在确定需要生成MAC PDU数据包时，可以确定在该MAC PDU数据包中的某一类型的MAC CE需要携带哪些辅小区的信息，然后根据该类型的每个MAC CE所对应的辅小区(MAC CE所对应的辅小区即指MAC CE需要携带这些辅小区的信息)，确定该类型的每个MAC CE在MAC PDU数据包中的位置，然后根据该类型的每个MAC CE在MAC PDU数据包中的位置进行MAC PDU数据包的封装，并将封装后的 该MAC PDU数据包发送至第二通信设备，从而第二通信设备在获取该MAC PDU数据包后，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息。
因此，在本发明实施例中，第一通信设备在生成MAC PDU数据包时，根据第一类型的MAC CE对应的辅小区确定第一类型的MAC CE在该MAC PDU数据包中的位置，从而第二通信设备在解析该MAC PDU数据包时，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息，从而在需要聚合的小区数量增多时，可以通过在一个MAC DPU数据包中携带多个该类型的MAC CE，每个该类型的MAC CE分别携带不同的辅小区的信息，并通过MAC CE在MAC PDU数据中的位置来决定该MAC CE所承载的是哪些辅小区的信息，从而可以不需要改变MAC CE的格式(例如，增加MAC CE组号或增加MAC CE长度所带来的改变)达到支持更多的小区聚合的目的，对协议改动较小，实现简单。
可选地，本发明实施例可以用于基站内小区聚合，也可以用于基站间小区聚合。
可选地，在本发明实施例中，为了支持更多的小区聚合，小区索引的取值范围扩展到大于7，比如扩展到31。
可选地，在本发明实施例中，第一类型的MAC CE可以是激活去激活MAC CE(Activation/Deactivation MAC CE)，第一通信设备是基站，第二通信设备是用户设备。或者，第一类型的MAC CE是扩展功率余量报告Extended PHR MAC CE或双连接功率余量报告Dual Connectivity PHR MAC CE，第一通信设备是用户设备，第二通信设备是基站。
可选地，在本发明实施例中，MAC PDU数据包还包括至少一个LCID，至少一个LCID与至少一个第一类型的MAC CE一一对应，其中，至少一个LCID中每个LCID用于指示各自对应的MAC CE为第一类型的MAC CE。
可选地，在本发明实施例中，每个所述第一类型的MAC CE包括Ci，i取值从1到7(即每个所述第一类型的MAC CE包括C1、C2一直到C7)，如果至少一个所述第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*7+1到(X-1)*7+7的辅小区信息，则所述第一MAC CE中的Ci对应小区索引为(X-1)*7+i的辅小区。
应理解，在第一类型的MAC CE为激活去激活MAC CE时，Ci的取值可以表示对应的小区的状态为激活状态还是去激活状态，例如1表示激活，0表示去激活。
在第一类型的MAC CE为扩展功率余量报告MAC CE或双连接功率余量报告MAC CE时，Ci取值可以表示对应的小区是否上报了功率余量信息，例如1表示上报，0表示未上报。应理解，在在第一类型的MAC CE为扩展功率余量报告MAC CE或双连接功率余量报告MAC CE时，MAC CE除了Ci之外，还可以包括其他信息，例如，如图5a，5b，6a和图6b所示。
应理解，在本发明实施例中，第一类型的每个MAC CE用于携带至少一个辅小区的信息是指每个该MAC CE所对应的辅小区的个数，例如，如果某用户设备共配置了8个辅小区，则在MAC PDU数据包中第一个第一类型的MAC CE中7个Ci(即i取值从1到7)均对应有辅小区的信息，而第二个该第一类型的MAC CE可以只在Ci(即i取值从1到7)其中的一个填充相应辅小区的信息，而其他位可以是无效信息，接收端可以不解析。
图4a所示的是第一类型的MAC CE为激活去激活MAC CE所属MAC PDU数据包的部分信息，共包含n个LCID和n个第一类型的MAC CE，n个LCID与n个第一类型的MAC CE一一对应，第一类型的每个MAC CE具有Ci，i取值从1到7，如果至少一个所述第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*7+1到(X-1)*7+7的辅小区的信息，则所述第一MAC CE中的Ci对应小区索引为(X-1)*7+i的辅小区，其中，图4a中，R代表保留字段，E代表是否当前的子头是该MAC PDU里的最后一个子头。
图4b是根据本发明实施例所适用的MAC CE格式图。在图4中，MAC CE包括C1，C2，C3，C3，C4，C5，C6和C7，分别表示对应的辅小区的信息，例如，如果该MAC CE为激活去激活MAC CE，C1，C2，C3，C3，C4，C5，C6和C7表示对应的小区的激活去激活状态，例如，1表示激活，0表示去集合；如果该MAC CE为扩展功率余量报告MAC CE或双连接功率余量报告MAC CE，则C1，C2，C3，C3，C4，C5，C6和C7表示是否上报了对应的小区的功率余量信息，例如，1表示上报，0表示未上报。应理解，在该MAC CE为扩展功率余量报告MAC CE或双连接功率余量报告MAC CE，该MAC CE还包括其他信息，例如，如图5a，5b，6a和图6b所示。
可选地，在本发明实施例中，第一通信设备根据具有该第一类型的MAC CE对应的辅小区确定具有该第一类型的MAC CE在该MAC PDU数据包中的位置，包括：
第一通信设备根据具有该第一类型的MAC CE对应的辅小区确定具有该第一类型的每个MAC CE在该MAC PDU数据包中第一类型的MAC CE中的位置，或具有该第一类型的每个MAC CE在该MAC PDU数据包中MAC CE中的位置，或具有该第一类型的每个MAC CE在该MAC PDU数据包中的MAC SDU、MAC CE和padding单元中的位置。
也就是说，某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该类型的所有MAC CE中的位置决定，可以由该MAC CE在所有MAC CE中的位置决定，也可以由该MAC CE在所有MAC SDU、MAC CE和padding单元中的位置决定。
为了便于理解，以下将结合两种情况进行详细说明。
在第一种情况中，用户设备的辅小区通过无线资源控制RRC信令进行分组，每个小区组分配一个组号，每个第一类型的MAC CE用于携带一个小区组下的辅小区的信息，第一通信设备根据第一类型的MAC CE对应的辅小区确定第一类型的MAC CE在MAC PDU数据包中的位置，包括：
如果至少一个第一类型的MAC CE中的第一MAC CE携带的是对应组号为X的辅小区的信息，则确定第一MAC CE是MAC PDU数据包中的第X个第一类型的MAC CE；或者
如果至少一个第一类型的MAC CE中的第一MAC CE携带的是对应组号为X的辅小区的信息，则确定第一MAC CE是MAC PDU数据包中的第X个MAC CE；或者
如果至少一个第一类型的MAC CE中的第一MAC CE携带的是对应组号为X的辅小区的信息，则确定第一MAC CE是MAC PDU数据包中所有MAC业务数据单元SDU，MAC CE，填充单元Padding的第X个单元。
具体地说，基站可以通过RRC信令对用户设备的辅小区进行分组，每个第一类型的MAC CE用于携带一个小区组下的辅小区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个小区分配一个小区组内的索引，Ci对应该小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该小区组内的小区中小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
在第二种情况中，每个第一类型的MAC CE用于携带N个辅小区的信息，该第一通信设备根据具有该第一类型的MAC CE对应的辅小区确定具有该第一类型的MAC CE在该MAC PDU数据包中的位置，包括：
如果至少一个第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息，则确定该第一MAC CE是该MAC PDU数据包中的第X个第一类型的MAC CE；也就是，该MAC PDU数据包中的第X个第一类型的MAC CE，携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息；优选地，如果该MAC PDU数据包里携带了多个第一类型的MAC CE，则这多个第一类型的MAC CE是连续存放的；或者
如果至少一个具有该第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息，则确定该第一MAC CE是该MAC PDU数据包中的第X个MAC CE；也就是，该MAC PDU数据包中的第X个MAC CE，携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息；或者
如果至少一个具有该第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息，则确定该第一MAC CE是该MAC PDU数据包中所有MAC SDU、MAC CE和padding单元中的第X个单元；也就是，该MAC PDU数据包中所有MAC SDU、MAC CE和padding单元中的第X个单元，携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息。
为了便于理解，以下结合图3a和图3b进行详细说明。其中，在结合图3a和图3b的说明中，均假设一个MAC CE支持7个辅小区，MAC PDU数据包最多支持31个辅小区，小区索引(index)为从1到31，且假设第一类型的MAC CE为激活去激活MAC CE，在MAC PDU数据包中至少需要包括小区索引8-14对应的激活去激活MAC CE。其他的情况，也是同理，这里不再累述，比如第一类型的MAC CE为Extended PHR MAC CE。
如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有该类型的MAC CE中的位置决定， 由于至少包括小区索引8-14对应的激活去激活MAC CE，则需要在所有第一类型的MAC CE中的第二个MAC CE中携带小区索引为8-14的辅小区的激活去激活状态。例如，在3a和图3b中，MAC CE2为小区索引为8-14的辅小区的对应的激活去激活MAC CE，则MAC CE1是小区索引1-7的辅小区的对应的激活去激活MAC CE；如果MAC CE3为小区索引8-14的辅小区的对应的激活去激活MAC CE，则MAC CE1或MAC CE2是小区索引1-7的辅小区的对应的激活去激活MAC CE；如果MAC CE4为小区索引8-14的辅小区的对应的激活去激活MAC CE，则MAC CE1，MAC CE2或MAC CE3是小区索引1-7的辅小区的对应的激活去激活MAC CE。
如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有MAC CE中的位置决定，由于至少包括小区索引8-14对应的激活去激活MAC CE，则需要在所有MAC CE中的第二个MAC CE中携带小区索引8-14对应的激活去激活状态。例如，在3a和图3b中，MAC CE2为小区索引8-14对应的激活去激活MAC CE，其中，MAC CE 1可以是小区索引1-7对应的激活去激活MAC CE，也可以是其他类型的MAC CE。
如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在MAC PDU数据包中所有MAC SDU、MAC CE和padding单元中的位置决定，由于至少包括小区索引8-14对应的激活去激活MAC CE，则需要将第二个单元确定为该小区索引8-14对应的激活去激活MAC CE。例如，在3a中，MAC CE2为小区索引8-14对应的激活去激活MAC CE，其中，MAC CE 1可以是小区索引1-7对应的激活去激活MAC CE，也可以是其他类型的MAC CE；在图3b中，MAC CE1为小区索引8-14对应的激活去激活MAC CE。
可选地，在本发明实施例中，在第一类型的MAC CE是激活去激活MAC CE时，基站将需要改变激活去激活状态的辅小区中具有最大小区索引的辅小区对应的MAC CE确定为至少一个第一类型的MAC CE中位置最靠后的MAC CE。
也就是说，在基站生成MAC PDU数据包时，基站可以不需将配置的所有辅小区对应的MAC CE均包括在MAC PDU数据包中，而是根据是否需要改变辅小区激活去激活状态，以及需要改变激活去激活状态的辅小区索引 中的最大小区索引，来确定需要携带哪些MAC CE，其中，MAC PDU数据包不需要携带这样的MAC CE：该MAC CE对应的辅小区中的最小索引大于需要改变激活去激活状态的辅小区的小区索引中的最大小区索引。以下将结合举例一和举例二进行描述：
在举例一中，假设配置了21个辅小区，每个某一类型的MAC CE共承载7个辅小区的信息，MAC CE 1承载索引为1-7的辅小区的信息，MAC CE 2承载索引为8-14的辅小区的信息，MAC CE 3承载15-21的辅小区的状态，如果需要小区索引5和13的辅小区的状态改变，则需要在MAC PDU数据包中包括该MAC CE1和MAC CE2。至于该MAC CE1和MAC CE2的排序可以包括以下三种情况：
1)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有第一类型的MAC CE中的位置决定，则需要在MAC PDU数据包中携带MAC CE 1和MAC CE 2，且MAC CE 1位置先于MAC CE 2，MAC CE1和MAC CE2在MAC PDU数据包中的绝对位置不限定。
2)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有MAC CE中的位置决定，则需要在MAC PDU数据包中携带MAC CE1和MAC CE2，MAC CE1需要是所有MAC CE中的第一个MAC CE和MAC CE2需要是所有MAC CE中的第二个MAC CE。
3)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在MAC PDU数据包中的所有MAC SDU、MAC CE和padding单元中的位置决定，则需要在MAC PDU数据包中携带MAC CE1和MAC CE2，MAC CE1是所有MAC SDU、MAC CE和padding单元的第一个单元和MAC CE2需要是所有MAC SDU、MAC CE和padding单元的第一个单元。
在举例2中，假设配置了21个辅小区，每个某一类型的MAC CE共承载7个辅小区的信息，MAC CE 1承载索引为1-7的辅小区的信息，MAC CE 2承载索引为8-14的辅小区的信息，MAC CE 3承载15-21的辅小区的状态，如果需要小区索引13的辅小区的状态改变，则至少需要在MAC PDU数据包中包括MAC CE2。至于是否需要包括其他MAC CE或者MAC CE的 排序，可以包括以下三种情况：
1)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有第一类型的MAC CE中的位置决定，因为需要状态改变的辅小区(小区索引为13的辅小区)属于索引8-14，即需要携带第二个具有该类型的MAC CE，则需要在该MAC CE2之前携带MAC CE1，也就是说，需要在MAC PDU数据包中携带MAC CE 1和MAC CE 2，且MAC CE 1位置先于MAC CE 2，MAC CE1和MAC CE2在MAC PDU数据包中的绝对位置不限定。
2)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该MAC PDU数据包中所有MAC CE中的位置决定，因为需要状态改变的辅小区(小区索引为13的辅小区)属于属于索引8-14，即需要携带第二个MAC CE，则需要在该MAC CE2之前携带MAC CE，MAC CE2之前的MAC CE可以是MAC CE1，也可以是其他类型的MAC CE。
3)、如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在MAC PDU数据包中的所有MAC SDU、MAC CE和padding单元中的位置决定，，因为需要状态改变的辅小区(小区索引为13的辅小区)属于属于索引8-14，即所有携带MAC SDU、MAC CE和padding单元中的第二个单元，则需要在该MAC CE2之前携带MAC CE1，也就是说，需要在MAC PDU数据包中携带MAC CE2，MAC CE2是所有MAC SDU、MAC CE和padding单元，MAC CE2之前的单元可以是MAC CE1，其他类型的MAC CE或者MAC SDU等。
或者，所述第一通信设备将需要改变激活去激活状态的辅小区中所属组号为最大的辅小区对应的MAC CE确定为至少一个所述第一类型的MAC CE中位置最靠后的MAC CE。
例如，类似于上文的举例一描述，假设配置了21个辅小区，每个某一类型的MAC CE共承载7个辅小区的信息，MAC CE 1承载索引为1-7的辅小区的信息，MAC CE 2承载索引为8-14的辅小区的信息，MAC CE 3承载15-21的辅小区的状态，如果需要小区索引5和13的辅小区的状态改变，则可以根据需要改变状态的小区索引的最大值来确定最后一个该类型的MAC CE，即根据小区索引13来确定MAC PDU数据包中最后一个该类型的MAC CE，即MAC CE2，也就是说不需要携带MAC CE3。因此，在本发 明实施例中，因为将需要改变激活去激活状态的辅小区中所属组号为最大的辅小区对应的MAC CE确定为位置最靠后的MAC CE，即不需要携带对应的小区索引大于该最大小区索引的同类型的MAC CE，从而可以节省信令开销。
可选地，在本发明实施例中，在第一类型的MAC CE为是扩展功率余量报告Extended PHR MAC CE或双连接功率余量报告Dual Connectivity PHR MAC CE时，所述第一通信设备将需要上报功率余量信息的辅小区中具有最大小区索引的辅小区对应的MAC CE确定为至少一个所述第一类型的MAC CE中位置最靠后的MAC CE。
也就是说，在基站生成MAC PDU数据包时，基站可以不需将配置的所有辅小区对应的MAC CE均包括在MAC PDU数据包中，而是根据是否需要上报辅小区的功率余量信息，以及需要上报功率余量信息的辅小区索引中的最大小区索引，来确定需要携带哪些MAC CE，其中，MAC PDU数据包不需要携带这样的MAC CE：该MAC CE对应的辅小区中的最小索引大于需要上报功率余量信息的辅小区的小区索引中的最大小区索引。
例如，假设配置了21个辅小区，每个某一类型的MAC CE共承载7个辅小区的信息，MAC CE 1承载索引为1-7的辅小区的信息，MAC CE 2承载索引为8-14的辅小区的信息，MAC CE 3承载15-21的辅小区的状态，如果需要小区索引5和13的辅小区的功率余量信息上报，则可以根据需要上报功率余量信息的小区索引的最大值来确定最后一个该类型的MAC CE，即根据小区索引13来确定MAC PDU数据包中最后一个该类型的MAC CE，即MAC CE2，也就是说不需要携带MAC CE3。因此，在本发明实施例中，因为将需要改变激活去激活状态的辅小区中所属组号为最大的辅小区对应的MAC CE确定为位置最靠后的MAC CE，即不需要携带对应的小区索引大于该最大小区索引的同类型的MAC CE，从而可以节省信令开销。
或者，所述第一通信设备将需要上报功率控制信息的辅小区中所属组号为最大的辅小区对应的MAC CE确定为至少一个所述第一类型的MAC CE中位置最靠后的MAC CE。其中，至于具体携带哪些第一类型的MAC CE以及如何排序请参考以上描述。
可选地，在本发明实施例中，在第一类型的MAC CE为是扩展功率余量报告Extended PHR MAC CE时，至少一个第一类型的MAC CE中的第一 个MAC CE还包括主小区的功率余量信息,至少一个第一类型的MAC CE中第一个之后的第一类型的MAC CE不包括主小区的功率余量信息，以避免重复信息上报，节省信令开销。
在此情况下，第一个Extended PHR MAC CE具体地信令结构可以如图5a所示，在图5a中，Ci用于指示相应的辅小区是否上报了对应的功率余量信息，PH(Type2，PCell)表示主小区的TYPE2的功率余量信息，PH(Type1，PCell)表示主小区的TYPE1的功率余量信息，PH(Type1，SCell)表示辅小区的TYPE1的功率余量信息，R为保留字段，PCMAC，P和V为其他功率信息，可参考现有技术，此处不再赘述。第一个之后的Extended PHR MAC CE具体地信令结构可以如图5b所示，在图5b中，Ci用于指示相应的辅小区是否上报了对应的功率余量信息，PH(Type1，SCell)表示辅小区的TYPE1的功率余量信息，PH(Type2，SCell)表示辅小区的TYPE2的功率余量信息，PCMAC，c，P和V为其他功率信息，可参考现有技术，此处不再赘述。
可选地，在本发明实施例中，在第一类型的MAC CE为双连接功率余量报告Dual Connectivity PHR MAC CE时，至少一个第一类型的MAC CE中的第一个MAC CE还包括主小区的功率余量信息和主辅小区的功率余量信息,至少一个第一类型的MAC CE中第一个之后的第一类型的MAC CE不包括主小区的功率余量信息和主辅小区的功率余量信息，以避免重复信息上报，节省信令开销。
在此情况下，第一个Dual Connectivity PHR MAC CE的信令格式可以如图6a所示，在图6a中，Ci用于指示相应的辅小区是否上报了对应的功率余量信息，PH(Type2，PCell)表示主小区的TYPE2的功率余量信息，PH(Type1，PCell)表示主小区的TYPE1的功率余量信息，PH(Type1，SCell)表示辅小区的TYPE1的功率余量信息，PH(Type2，PSCell)表示主辅小区的TYPE2的功率余量信息，R为保留字段，PCMAC，P和V为其他功率信息，可参考现有技术，此处不再赘述。第一个之后的Dual Connectivity PHR MAC CE的信令格式可以如图6b所示，在图6b中，Ci用于指示相应的辅小区是否上报了对应的功率余量信息，PH(Type1，SCell)表示辅小区的TYPE1的功率余量信息，R为保留字段，PCMAC，P和V为其他功率信息，可参考现有技术，此处不再赘述。
可选地，在本发明实施例中，当所述第一类型的MAC CE指示辅小区的功率余量信息被携带，并且所述辅小区具有PUCCH时，所述第一类型的MAC CE还包括所述辅小区的TYPE 2功率余量信息。
因此，在本发明实施例中，第一通信设备在生成MAC PDU数据包时，根据第一类型的MAC CE对应的辅小区确定第一类型的MAC CE在该MAC PDU数据包中的位置，从而第二通信设备在解析该MAC PDU数据包时，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息，从而在需要聚合的小区数量增多时，可以通过在一个MAC DPU数据包中携带多个该类型的MAC CE，每个该类型的MAC CE分别携带不同的辅小区的信息，并通过MAC CE在MAC PDU数据中的位置来决定该MAC CE所承载的是哪些辅小区的信息，从而可以不需要改变MAC CE的格式(例如，增加MAC CE组号或增加MAC CE长度所带来的改变)达到支持更多的小区聚合的目的，对协议改动较小，实现简单。
在本发明实施例中，还提供另外一种通信方法，可以解决如何在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量的问题。以下将图12中的方法700和图13中的方法800进行说明。
如图12所示，该方法700包括：
710，基站确定需要激活第一辅小区，其中，所述第一辅小区所属的第一辅小区组中所有辅小区处于去激活状态；
720，基站生成第一MAC PDU数据包，所述第一MAC PDU数据包包括第一激活去激活MAC CE，所述第一激活去激活MAC CE包括指示信息，所述指示信息用于指示激活所述第一辅小区，或者用于指示激活所述第一辅小区组；
730，基站通过主小区向用户设备发送所述第一MAC PDU，以便于所述用户设备激活所述第一辅小区或所述第一辅小区组。
可选地，第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态，其中，N个辅小区中不同的辅小区分别属于N个辅小区组中不同的辅小区组。
也就是说，第一MAC CE包括指示信息，也即Ci(i取值从1到N)，用 于指示N个辅小区的激活去激活状态，且N个辅小区中不同的辅小区属于不同的辅小区组。
可选地，在第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态时，基站确定需要激活第一辅小区，包括：基站根据需要激活第二辅小区确定需要激活所述第一辅小区，其中，所述第二辅小区属于所述第一辅小区组，所述；以及在用户设备激活所述第一辅小区之后，所述方法700还包括：
基站生成第二MAC PDU数据包，所述第一MAC PDU数据包包括第二激活去激活MAC CE，所述第二激活去激活MAC CE对应于所述第一辅小区组，用于指示所述第一辅小区组中的激活去激活状态，且在所述第二激活去激活MAC CE中，所述第二辅小区的状态为激活；
所述基站通过所述第一辅小区向所述用户设备发送所述第二MAC PDU，以便于所述第二用户设备激活所述第二辅小区。
具体地说，可以为每个组内的至少一个辅小区分配一个在主小区所在组下的索引；这样当某组下的所有小区都去激活后，可以通过主小区激活该某组中在主小区所在组具有小区索引的小区，并进一步通过该小区来激活该某组中其他小区；当然，因为该小区在该某组中也分配了索引，也可以通过该某组下的小区进行激活去激活。应理解，本发明中提到的主小区所在的组可以是这样一个小区组：该组包括主小区以及每个辅小区组中的至少一个辅小区。
可选地，第一激活去激活MAC CE用于指示N个辅小区组的激活去激活状态。
也就是说，第一MAC CE包括Ci(i取值从1到N)，用于指示N个辅小区组的激活去激活状态；例如，C1指示第一个辅小区组的状态为激活，从而可以激活第一个辅小区组中的所有辅小区；再例如，C2指示第二个辅小区组的状态为去激活，从而可以去激活第二个辅小区组中的所有辅小区。
具体地说，每个小区组分配一个组号，每个小区组对应MAC CE里的一个比特，通过主小区下发的MACCE用来激活去激活的是小区组，通过辅小区下发的MACCE用来激活去激活的是该辅小区对应的小区组下的小区。
可选地，基站可以对用户设备的辅小区进行分组(通过无线资源控制RRC信令进行分组)，每个第一类型的MAC CE用于携带一个辅小区组下的辅小 区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个辅小区分配一个辅小区组内的索引，Ci对应该辅小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该辅小区组内的小区中小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
因此，以上方法可以解决以下问题：第一类型的MAC CE中不携带辅小区组号信息，发送方在该MAC CE对应的辅小区组下的小区上发送该第一类型的MAC CE，接收方根据接收该MAC CE的辅小区，获知该第一类型的MAC CE是对应这个辅小区所属的辅小区组。然而，当一个小区组的所有小区都被去激活了，则无法通过该辅小区组下的辅小区发送该MAC CE来进行激活的问题
因此，以上实施例可以在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量。
如图13所示，方法800包括：
810，用户设备通过主小区接收第一MAC PDU数据包，所述第一MAC PDU数据包包括第一激活去激活MAC CE，所述第一激活去激活MAC CE包括指示信息，所述指示信息用于指示激活第一辅小区，或者用于指示激活第一辅小区组；
820，所述用户设备根据所述第一MAC CE，激活所述第一辅小区或激活所述第一辅小区组。
可选地，第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态，其中，N个辅小区中的不同的辅小区分别属于N个辅小区组中不同的辅小区组。
也就是说，第一MAC CE包括指示，也即Ci(i取值从1到N)，用于指示N个辅小区的激活去激活状态，而每个辅小区都分别属于一个辅小区组，且N个辅小区中不同的辅小区属于不同的辅小区组。
可选地，在第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态时，在激活所述第一辅小区之后，所述方法800还包括：
用户设备通过所述第一辅小区接收第二MAC PDU数据包，所述第二 MAC PDU数据包包括第二激活去激活MAC CE，所述第二激活去激活MAC CE对应于所述第一辅小区组，用于指示所述第一辅小区组中的激活去激活状态，所述第二辅小区和所述第一辅小区属于所述第一辅小区组，且在所述第二激活去激活MAC CE中，所述第二辅小区的状态为激活；
所述用户设备根据所述第二MAC PDU数据包，激活所述第二小区。
具体地说，可以为每个组内的至少一个辅小区分配一个在主小区所在组下的索引；这样当某组下的所有小区都去激活后，可以通过主小区激活该某组中在主小区所在组具有小区索引的小区，并进一步通过该小区来激活该某组中其他小区；当然，因为该小区在该某组中也分配了索引，也可以通过该某组下的小区进行激活去激活。
可选地，第一激活去激活MAC CE用于指示N个辅小区组的激活去激活状态。
也就是说，第一MAC CE包括Ci(i取值从1到N)，用于指示N个辅小区组的激活去激活状态；例如，C1指示第一个辅小区组的状态为激活，从而可以激活第一个辅小区组中的所有辅小区；再例如，C2指示第二个辅小区组的状态为去激活，从而可以去激活第二个辅小区组中的所有辅小区。
具体地说，每个小区组分配一个组号，每个小区组对应MAC CE里的一个比特，通过主小区下发的MACCE用来激活去激活的是小区组，通过辅小区下发的MACCE用来激活去激活的是该辅小区对应的小区组下的小区。
可选地，基站可以对用户设备的辅小区进行分组(通过无线资源控制RRC信令进行分组)，每个第一类型的MAC CE用于携带一个辅小区组下的辅小区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个辅小区分配一个辅小区组内的索引，Ci对应该辅小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该辅小区组内的辅小区中辅小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
因此，以上方法可以解决以下问题：第一类型的MAC CE中不携带小区组号信息，发送方在该MAC CE对应的小区组下的小区上发送该第一类型的MAC CE，接收方根据接收该MAC CE的小区，获知该第一类型的MAC CE是对应这个小区所属的小区组。然而，当一个小区组的所有小区都被去 激活了，则无法通过该小区组下的小区发送该MAC CE来进行激活的问题
因此，以上实施例可以在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量。
图7是根据本发明实施例的通信方法200的示意性流程图。如图7所示，该方法200包括：
210，第二通信设备获取第一通信设备发送的MAC PDU数据包，该MAC PDU数据包包括至少一个第一类型的MAC控制单元CE，第一类型的每个MAC CE用于携带至少一个辅小区的信息；
220，第二通信设备获取第一类型的MAC CE，并根据第一类型的MAC CE在MAC PDU数据包中的位置确定第一类型的MAC CE对应的辅小区以获取辅小区的信息。
具体地说，第一通信设备在确定需要生成MAC PDU数据包时，可以确定在该MAC PDU数据包中的某一类型的MAC CE需要携带哪些辅小区的信息，然后根据该类型的每个MAC CE所对应的辅小区(MAC CE所对应的辅小区即指MAC CE需要携带这些辅小区的信息)，确定该类型的每个MAC CE在MAC PDU数据包中的位置，然后根据该类型的每个MAC CE在MAC PDU数据包中的位置进行MAC PDU数据包的封装，并将封装后的该MAC PDU数据包发送至第二通信设备，从而第二通信设备在获取该MAC PDU数据包后，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息。
因此，在本发明实施例中，第一通信设备在生成MAC PDU数据包时，根据第一类型的MAC CE对应的辅小区确定第一类型的MAC CE在该MAC PDU数据包中的位置，从而第二通信设备在解析该MAC PDU数据包时，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息，从而在需要聚合的小区数量增多而导致MAC CE的数量增多时，可以通过MAC CE在MAC PDU数据中的位置来决定该MAC CE所承载的是哪些辅小区的信息，从而可以不需要改变MAC CE的格式(例如，增加MAC CE组号或增加MAC CE长度所带来的改变)，对协议改动较小，实现简单。
可选地，本发明实施例可以用于基站内小区聚合，也可以用于基站间小 区聚合。
可选地，在本发明实施例中，第一类型的MAC CE可以是激活去激活MAC CE(Activation/Deactivation MAC CE)，第一通信设备是基站，第二通信设备是用户设备。或者，第一类型的MAC CE是Extended PHR MAC CE或Dual Connectivity PHR MAC CE，第一通信设备是用户设备，第二通信设备是基站。

可选地，在本发明实施例中，每个所述第一类型的MAC CE包括Ci，i取值从1到7(即每个所述第一类型的MAC CE包括C1、C2一直到C7)，如果至少一个所述第一类型的MAC CE中的第一MAC CE携带的是对应小区索引为(X-1)*7+1到(X-1)*7+7的辅小区信息，则所述第一MAC CE中的Ci对应小区索引为(X-1)*7+i的辅小区。

也就是说，某一类型的某一MAC CE对应哪些辅小区的信息可以由该MAC CE在该类型的所有MAC CE中的位置决定，可以由该MAC CE在所有MAC CE中的位置决定，也可以由该MAC CE在所有MAC SDU、MAC CE和padding单元中的位置决定。
为了便于理解，以下将结合两种情况进行详细说明。
在第一种情况中，用户设备的辅小区通过无线资源控制RRC信令进行 分组，每个小区组分配一个组号，每个第一类型的MAC CE用于携带一个小区组下的辅小区的信息，根据第一类型的MAC CE在MAC PDU数据包中的位置确定第一类型的MAC CE对应的辅小区并获取辅小区的信息，可以包括：
如果至少一个第一类型的MAC CE中的第一MAC CE的位置是MAC PDU数据包中的第X个第一类型的MAC CE，则确定第一MAC CE携带的是对应组号为X的辅小区的信息；或者
如果至少一个第一类型的MAC CE中的第一MAC CE的位置是MAC PDU数据包中的第X个MAC CE，则确定第一MAC CE携带的是对应组号为X的辅小区的信息；或者
如果至少一个第一类型的MAC CE中的第一MAC CE的位置是MAC PDU数据包中MAC SDU、MAC CE和padding单元中的第X个单元，则确定第一MAC CE携带的是对应组号为X的辅小区的信息。
具体地说，基站可以通过RRC信令对用户设备的辅小区进行分组，每个第一类型的MAC CE用于携带一个小区组下的辅小区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个小区分配一个小区组内的索引，Ci对应该小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该小区组内的小区中小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
为了便于理解，以下结合图3a和图3b进行详细说明。其中，在结合图3a和图3b的说明中，此处假设MAC PDU数据包最多承载5组辅小区，一组辅小区包括7个辅小区，每组辅小区映射到一个MAC CE。

在第二种情况中，根据第一类型的MAC CE在MAC PDU数据包中的位置确定第一类型的MAC CE对应的辅小区并获取辅小区的信息，可以包括：

如果至少一个第一类型的MAC CE中的第一MAC CE的位置是MAC PDU数据包中的第X个MAC CE，则确定第一MAC CE对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区；也就是，该MAC PDU数据包中的第X个MAC CE携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息；或者
如果至少一个第一类型的MAC CE中的第一MAC CE的位置是MAC PDU数据包中所有MAC SDU、MAC CE和padding单元中的第X个单元，则确定第一MAC CE对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区；也就是，该MAC PDU数据包中所有MAC SDU、MAC CE和padding单元中的第X个单元，携带的是对应小区索引为(X-1)*N+1到(X-1)*N+N的辅小区的信息。
为了便于理解，以下结合图3a和图3b进行详细说明。其中，在结合图3a和图3b的说明中，此处假设一个MAC CE支持7个辅小区，MAC PDU数据包最多支持31个辅小区，小区索引(index)为从1到31。
如果按照某一类型的某一MAC CE对应哪些辅小区的信息可以由该 MAC CE在该MAC PDU数据包中所有该类型的MAC CE中的位置决定，且假设在图3a中，MAC CE1和MAC CE2为第一类型的MAC CE，则MAC CE1携带有小区索引1-7的辅小区的信息，MAC CE2携带有小区索引8-14的辅小区的信息。

因此，在本发明实施例中，第一通信设备在生成MAC PDU数据包时，根据第一类型的MAC CE对应的辅小区确定第一类型的MAC CE在该MAC PDU数据包中的位置，从而第二通信设备在解析该MAC PDU数据包时，可以根据该类型的每个MAC CE在MAC PDU数据包中的位置，确定该类型的每个MAC CE所对应的辅小区以获取辅小区的信息，从而在需要聚合的小区数量增多时，可以通过在一个MAC DPU数据包中携带多个该类型的MAC CE，每个该类型的MAC CE分别携带不同的辅小区的信息，并通过MAC CE在MAC PDU数据中的位置来决定该MAC CE所承载的是哪些辅小区的信息，从而可以不需要改变MAC CE的格式(例如，增加MAC CE组号或增加MAC CE长度所带来的改变)达到支持更多的小区聚合的目的，对协议改动较小，实现简单。

图14是根据本发明实施例的基站900的示意性框图。如图14所示，该基站900包括
确定单元910，用于确定需要激活第一辅小区，其中，所述第一辅小区所属的第一辅小区组中所有辅小区处于去激活状态；
生成单元920，用于生成第一MAC PDU数据包，所述第一MAC PDU数据包包括第一激活去激活MAC CE，所述第一激活去激活MAC CE包括指示信息，所述指示信息用于指示激活所述第一辅小区，或者用于指示激活所述第一辅小区组；
发送单元930，用于通过主小区向用户设备发送所述第一MAC PDU，以便于所述用户设备激活所述第一辅小区或所述第一辅小区组。
可选地，第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态，其中，N个辅小区中的不同的辅小区分别属于N个辅小区组中不同的辅小区组。
也就是说，第一MAC CE包括指示信息，也即Ci(i取值从1到N)，用于指示N个辅小区的激活去激活状态，且N个辅小区中不同的辅小区属于不同的辅小区组。
可选地，在第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态时，所述确定单元910还用于：根据需要激活第二辅小区确定需要激活所述第一辅小区，其中，所述第二辅小区属于所述第一辅小区组，所述；以及在用户设备激活所述第一辅小区之后，
所述生成单元920还用于：生成第二MAC PDU数据包，所述第一MAC PDU数据包包括第二激活去激活MAC CE，所述第二激活去激活MAC CE对应于所述第一辅小区组，用于指示所述第一辅小区组中的激活去激活状态，且在所述第二激活去激活MAC CE中，所述第二辅小区的状态为激活；
所述发送单元930还用于：通过所述第一辅小区向所述用户设备发送所述第二MAC PDU，以便于所述第二用户设备激活所述第二辅小区。
具体地说，可以为每个组内的至少一个辅小区分配一个在主小区所在组下的索引；这样当某组下的所有小区都去激活后，可以通过主小区激活该某 组中在主小区所在组具有小区索引的小区，并进一步通过该小区来激活该某组中其他小区；当然，因为该小区在该某组中也分配了索引，也可以通过该某组下的小区进行激活去激活。应理解，提到的主小区所在的组可以是这样一个小区组：该组包括主小区以及每个辅小区组中的至少一个辅小区。
可选地，第一激活去激活MAC CE用于指示N个辅小区组的激活去激活状态。
也就是说，第一MAC CE包括Ci(i取值从1到N)，用于指示N个辅小区组的激活去激活状态；例如，C1指示第一个辅小区组的状态为激活，从而可以激活第一个辅小区组中的所有辅小区；再例如，C2指示第二个辅小区组的状态为去激活，从而可以去激活第二个辅小区组中的所有辅小区。
具体地说，每个小区组分配一个组号，每个小区组对应MAC CE里的一个比特，通过主小区下发的MACCE用来激活去激活的是小区组，通过辅小区下发的MACCE用来激活去激活的是该辅小区对应的小区组下的小区。
可选地，基站可以对用户设备的辅小区进行分组(通过无线资源控制RRC信令进行分组)，每个第一类型的MAC CE用于携带一个辅小区组下的辅小区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个辅小区分配一个辅小区组内的索引，Ci对应该辅小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该辅小区组内的小区中小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
因此，以上方法可以解决以下问题：第一类型的MAC CE中不携带辅小区组号信息，发送方在该MAC CE对应的辅小区组下的小区上发送该第一类型的MAC CE，接收方根据接收该MAC CE的辅小区，获知该第一类型的MAC CE是对应这个辅小区所属的辅小区组。然而，当一个小区组的所有小区都被去激活了，则无法通过该辅小区组下的辅小区发送该MAC CE来进行激活的问题
因此，以上实施例可以在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量。
图15是根据本发明实施例中的用户设备1000的示意性框图。如图15所 示，该用户设备1000包括：
接收单元1010，用于通过主小区接收第一MAC PDU数据包，所述第一MAC PDU数据包包括第一激活去激活MAC CE，所述第一激活去激活MAC CE包括指示信息，所述指示信息用于指示激活第一辅小区，或者用于指示激活第一辅小区组；

也就是说，第一MAC CE包括指示，也即Ci(i取值从1到N)，用于指示N个辅小区的激活去激活状态，而每个辅小区都分别属于一个辅小区组，且N个辅小区中不同的辅小区属于不同的辅小区组。
可选地，在第一激活去激活MAC CE用于指示N个辅小区的激活去激活状态时，在激活所述第一辅小区之后，
所述接收单元1010还用于：通过所述第一辅小区接收第二MAC PDU数据包，所述第二MAC PDU数据包包括第二激活去激活MAC CE，所述第二激活去激活MAC CE对应于所述第一辅小区组，用于指示所述第一辅小区组中的激活去激活状态，所述第二辅小区和所述第一辅小区属于所述第一辅小区组，且在所述第二激活去激活MAC CE中，所述第二辅小区的状态为激活；
所述激活单元1020还用于：根据所述第二MAC PDU数据包，激活所述第二小区。
具体地说，可以为每个组内的至少一个辅小区分配一个在主小区所在组下的索引；这样当某组下的所有小区都去激活后，可以通过主小区激活该某组中在主小区所在组具有小区索引的小区，并进一步通过该小区来激活该某组中其他小区；当然，因为该小区在该某组中也分配了索引，也可以通过该某组下的小区进行激活去激活。
可选地，第一激活去激活MAC CE用于指示N个辅小区组的激活去激活状态。
也就是说，第一MAC CE包括Ci(i取值从1到N)，用于指示N个辅小 区组的激活去激活状态；例如，C1指示第一个辅小区组的状态为激活，从而可以激活第一个辅小区组中的所有辅小区；再例如，C2指示第二个辅小区组的状态为去激活，从而可以去激活第二个辅小区组中的所有辅小区。
具体地说，每个小区组分配一个组号，每个小区组对应MAC CE里的一个比特，通过主小区下发的MACCE用来激活去激活的是小区组，通过辅小区下发的MACCE用来激活去激活的是该辅小区对应的小区组下的小区。
可选地，基站可以对用户设备的辅小区进行分组(通过无线资源控制RRC信令进行分组)，每个第一类型的MAC CE用于携带一个辅小区组下的辅小区的信息，至于每一个MAC CE中的比特如何进行辅小区的映射，可以采用以下两种方式：
1)、每个辅小区分配一个辅小区组内的索引，Ci对应该辅小区组内索引为i的辅小区。
2)、根据辅小区的小区索引的大小顺序分别对应Ci，比如该辅小区组内的辅小区中辅小区索引最小的辅小区对应C1，稍次的对应C2，依次类推。
因此，以上方法可以解决以下问题：第一类型的MAC CE中不携带小区组号信息，发送方在该MAC CE对应的小区组下的小区上发送该第一类型的MAC CE，接收方根据接收该MAC CE的小区，获知该第一类型的MAC CE是对应这个小区所属的小区组。然而，当一个小区组的所有小区都被去激活了，则无法通过该小区组下的小区发送该MAC CE来进行激活的问题
因此，以上实施例可以在不改变信令结构，即保持MAC CE的结构和sub-header的结构的基础上，增加聚合小区的数量或者灵活改变聚合的小区的数量。
