Description
本申请涉及通信领域,尤其涉及一种小区配置方法、基站和终端设备。
为了满足长期演进技术升级版((Long Term Evolution-Advanced,LTE-A)的下行峰速1Gbps,上行峰速500Mbps的要求,需要提供最大100MHz的传输带宽,但由于该传输带宽的连续频谱的稀缺,LTE-A提出了载波聚合(Carrier Aggregation,CA)的解决方案。CA是将2个或更多的成员载波(Component Carrier,CC)聚合在一起以支持更大的传输带宽(最大为100MHz)。实际上,每个CC对应一个独立的小区(cell),每个CC的最大带宽为20MHz。配置了CA之后,用户设备(User Equipment,UE)能够同时与多个小区进行收发数据的操作,因此能够提高UE的吞吐量。
随着异构网络的部署,小小区(small cell)部署变得更加普遍。在LTE Rel-13中,UE进行的CA操作被扩展到32个载波,CC个数大大增加。其中1个载波对应的小区可以作为主小区(Primary Cell,PCell)为UE提供服务,其余31个载波对应的小区可以作为辅小区(Secondary Cell,SCell)为UE提供服务。在CA场景中,PCell作为UE的移动性锚点可减少UE的切换操作,SCell被密集部署在不同的频率上用于提升用户面容量。
在LTE CA中,当UE进入无线资源控制(Radio Resource Control,RRC)连接态后,基站发送RRC连接重配置(connection reconfiguration)消息,其中携带为UE配置的一个或多个SCell的配置信息。被配置的SCell的状态默认是去激活的,在使用SCell进行数据传输之前,基站需要发送激活媒质接入控制(Medium Access Control,MAC)信元(ControlElement,CE)来激活配置的SCell,以便进行UE数据传输。但是,SCell的覆盖范围很小,随着UE的移动,UE的SCell的服务质量会快速发生改变,因此,UE的SCell将被频繁的配置或去配置,或在配置后频繁地对SCell激活或去激活,信令开销大。而且,当小小区的部署变得更加密集,且UE进行CA操作的载波个数超过5个(最多可能32个)时,基站用于配置SCell的RRC连接重配置消息的信令开销也比较高,用于激活或去激活SCell的MAC CE占用的比特数也比较大,例如可以为32bit,也会使得信令开销大。

于指示终端设备将至少一个小区中,N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的辅小区的配置信息。这样,终端设备的小区的配置不会因为终端设备的移动而被频繁的配置,终端设备的小区的配置可以在较长时间段中半静态改变,降低了第一配置消息的发送频率,使得信令开销降低。而且,第二配置消息中携带小区的索引或组的索引而不携带小区的具体配置信息,可使得第二配置消息占用的比特大小大大降低,使得信令开销进一步降低。
在一种可能的设计中,第一配置消息为***消息或无线资源控制RRC消息,第二配置消息为RRC消息、或媒体介入控制信元MAC CE、或物理下行控制信道PDCCH信令。对于空闲态的终端设备,第一配置消息可以为***消息,对于连接态的终端设备,第一配置消息可以为RRC消息。
在一种可能的设计中,第二配置消息还用于指示终端设备激活终端设备的辅小区。这样,基站在向终端设备配置辅小区时,第二配置消息可以起到配置的作用,还可以兼有激活的作用,不需要再配置后再发送激活消息给终端设备,以进一步降低信令开销。
在一种可能的设计中,至少一个小区的配置信息包括至少一个小区的公共信息和至少一个小区中每个小区特定的信息,公共信息携带在第一配置消息的公共信息字段中,公共信息字段的数量小于至少一个小区的数量。这样相对于在发送第一配置消息时,分别携带每个小区的配置信息,本申请在第一配置消息中各个小区的公共信息出现次数小于至少一个小区的数量,可以进一步降低比特占用大小,减小信令开销。公共信息在所述第一配置消息中N次重复,可以认为存在N个公共信息字段。(N为正整数)
在一种可能的设计中,公共信息字段的数量为1。即本申请在第一配置消息中各个小区的公共信息出现次数为一次,可以进一步降低比特占用大小,减小信令开销。
在一种可能的设计中,若每个小区的配置信息包括该小区的索引,则每个小区的配置信息还包括该小区的物理小区标识PCI、载波频率以及无线资源配置中的至少一种;或,若每个小区的配置信息包括该小区所属的一组小区的组的索引,则每组小区的配置信息包括该组小区的组的索引,以及该组小区中每个小区的PCI、载波频率以及无线资源配置中的至少一种。第一配置消息中携带一组小区的组的索引以及每组中各个小区的索引,相对于只携带每个小区的索引,在发送第二配置消息时可以只携带所要配置为辅小区的组的索引,可以进一步减小第二配置消息的比特占用大小。

在一种可能的设计中,该方法还包括:基站向终端设备发送第五配置消息,第五
配置消息为RRC消息,第五配置消息包括终端设备的辅小区的分组信息,分组信息包括每组辅小区的组的标识以及每组辅小区包括的小区的索引;基站向终端设备发送第一MAC CE或第二MAC CE,第一MAC CE包括每组辅小区的组的标识对应的比特信息,第二MAC CE包括至少一组辅小区的组的标识以及至少一组辅小区的组的标识对应的比特信息;其中,任一组辅小区的组的标识对应的比特信息为第一比特值或第二比特值,第一比特值用于指示该组辅小区包括的每个辅小区激活,第二比特值用于指示该组辅小区包括的每个辅小区去激活。也就是说,基站在为终端设备配置了辅小区后,可以进一步将辅小区分组,进而在后续发送激活消息激活辅小区时,可以携带待激活的辅小区的组的标识和比特信息,以指示辅小区激活/去激活。相对于携带每个辅小区的索引及其对应的激活/去激活的指示,可以降低激活消息的比特占用大小。

为了便于理解,示例地给出了部分与本申请相关概念的说明以供参考。如下所示:
PCell:是终端设备进行初始连接建立的小区,或进行RRC连接重建的小区,或是在切换(handover)过程中指定的主小区。PCell负责与终端设备之间的RRC通信。
SCell:是在RRC重配置时添加的小区,用于提供额外的无线资源,SCell与终端设备之间不存在任何RRC通信。PCell是在连接建立(connection establishment)时确定的,SCell是在初始安全激活流程(initialsecurity activation procedure)之后,通过RRC连接重配置(connection reconfiguration)消息添加/修改/释放的。
小(small)小区:低功率的无线接入节点,工作在授权的、非授权的频谱,可以覆盖10米到200米的范围。
宏(macro)小区:覆盖半径大多为1km~25km。由于覆盖半径较大,所以宏小区对应的基站的发射功率较强,一般在10W以上。
本申请可应用于在CA场景下为终端设备进行SCell的配置,以及对SCell进行激活或去激活。如图1所示,终端设备在基站的宏小区的覆盖范围内移动,宏小区和小小区部署在不同的频率层上。对于进行CA操作终端设备,宏小区作为终端设备的主小区,密集部署的小小区可被配置为终端设备的辅小区,以提升终端设备的数据速率。
本申请的网络架构可以包括基站和终端设备。
基站是一种在无线接入网用以提供无线通信功能的装置。例如基站可以为LTE中的演进型基站(evolved Node B,eNB)、家庭演进基站(Home evolved Node B,HeNB)、中继(Relay Node,Relay)、家庭基站(Home eNode B)(也可称为Femto cell)、微微(Pico)基站等。在5G通信***中,基站可以为eNB、新无线节点B(New Radio NodeB,gNB),集中单元(Centralized Unit,CU),分布式单元(Distributed Unit)和新无线控制器等。
终端设备可以是可移动的终端设备,也可以是不可移动的终端设备。该设备主要
用于接收或者发送业务数据。终端设备可分布于网络中,在不同的网络中用户设备有不同的名称,例如:UE、终端,移动台,用户单元,站台,蜂窝电话,个人数字助理,无线调制解调器,无线通信设备,手持设备,膝上型电脑,无绳电话,无线本地环路台等。该终端设备可以经无线接入网(radio access network,RAN)(无线通信网络的接入部分)与一个或多个核心网进行通信,例如与无线接入网交换语音和/或数据。
在一个示例中,基站200可以通过如图2所示的结构实现。图2示出了一种基站的通用硬件架构。图2所示的基站可以包括室内基带处理单元(building baseband unit,BBU)和远端射频模块(remote radio unit,RRU),RRU和天馈***(即天线)连接,BBU和RRU可以根据需要拆开使用。应注意,在具体实现过程中,基站200还可以采用其他通用硬件架构,而并非仅仅局限于图2所示的通用硬件架构。在本申请实施例中,RRU可以通过天馈***向终端设备发送配置消息或更新消息等。
在一个示例中,终端设备300可以通过如图3所示的结构实现。以终端设备300为手机为例,图3示出了手机的通用硬件架构进行说明。图3所示的手机可以包括:射频(radio Frequency,RF)电路310、存储器320、其他输入设备330、显示屏340、传感器350、音频电路360、I/O子***370、处理器380、以及电源390等部件。本领域技术人员可以理解,图3所示的手机的结构并不构成对手机的限定,可以包括比图示更多或者更少的部件,或者组合某些部件,或者拆分某些部件,或者不同的部件布置。本领域技术人员可以理解显示屏340属于用户界面(user Interface,UI),显示屏340可以包括显示面板341和触摸面板342。且手机可以包括比图示更多或者更少的部件。尽管未示出,手机还可以包括摄像头、蓝牙模块等功能模块或器件,在此不再赘述。
进一步地,处理器380分别与RF电路310、存储器320、音频电路360、I/O子***370、以及电源390均连接。输入/输出(Input/Output,I/O)子***370分别与其他输入设备330、显示屏340、传感器350均连接。其中,RF电路310可用于收发信息或通话过程中,信号的接收和发送,特别地,将基站的下行信息接收后,给处理器380处理。例如在本申请实施例中,RF电路310用于接收基站发送的配置消息或更新消息等。存储器320可用于存储软件程序以及模块。处理器3180通过运行存储在存储器320的软件程序以及模块,从而执行手机的各种功能应用以及数据处理。其他输入设备330可用于接收输入的数字或字符信息,以及产生与手机的用户设置以及功能控制有关的键信号输入。显示屏340可用于显示由用户输入的信息或提供给用户的信息以及手机的各种菜单,还可以接受用户输入。传感器350可以为光传感器、运动传感器或者其他传感器。音频电路360可提供用户与手机之间的音频接口。I/O子***370用来控制输入输出的外部设备,外部设备可以包括其他设备输入控制器、传感器控制器、显示控制器。处理器380是手机300的控制中心,利用各种接口和线路连接整个手机的各个部分,通过运行或执行存储在存储器320内的软件程序和/或模块,以及调用存储在存储器320内的数据,执行手机300的各种功能和处理数据,从而对手机进行整体监控。电源390(比如电池)用于给上述各个部件供电,优选的,电源可以通过电源管理***与处理器380逻辑相连,从而通过电源管理***实现管理充电、放电、以及功耗等功能。
本申请的基本原理为:基站通过第一配置消息向终端设备提供至少一个小区的配置信息,小区的配置信息包括小区的索引或小区所在的一组小区的组的索引,终端设备存储小区的配置信息。基站通过第二配置消息向终端设备提供待配置为辅小区的小区的索引或组的索引,其中小区的具体配置信息不在第二配置消息中携带,终端设备可根据小区的索引或组的索引在小区的配置信息中获取辅小区的配置信息。这样,终端设备的小区的配置不会因为终端设备的移动而被频繁的配置,终端设备的小区的配置可以在较长时间段中半静态改变,降低了第一配置消息的发送频率,使得信令开销降低。而且,第二配置消息中携带小区的索引或组的索引而不携带小区的具体配置信息,可使得第二配置消息占用的比特大小大大降低,使得信令开销进一步降低。
下面对本申请的实施例进行说明。
本申请实施例提供一种小区配置方法,该实施例中的小区可以理解为小小区,如图4所示,包括:
401、基站向用户设备终端设备发送第一配置消息,第一配置消息包括至少一个小区的配置信息,每个小区的配置信息包括该小区的索引或该小区所属的一组小区的组的索引。
示例性的,可以假设小区的配置更新不频繁,即在较长时间段中半静态改变。因此基站可以将多个小区的配置信息先通过第一配置消息发送给终端设备,之后再指示终端设备被配置为SCell的小区。
可选的,第一配置消息可以为***消息或无线资源控制RRC消息。例如,若基站确定终端设备处于空闲态,则第一配置消息可以为***消息;若基站确定UE处于连接态,则第一配置消息可以为专用的RRC消息。
在一种可能的设计中,若每个小区的配置信息包括该小区的索引,则每个小区的配置信息还包括该小区的物理小区标识PCI、载波频率以及无线资源配置中的至少一种。无线资源配置可以包括物理信道、上行和下行发送信号时的配置信息等。
在一个示例中,至少一个小区的配置信息包括至少一个小区的公共信息和至少一个小区中每个小区特定的信息,公共信息携带在第一配置消息的公共信息字段,公共信息字段的数量小于至少一个小区的数量。也就是说,至少一个小区的配置信息中的公共信息可以重复多次,但是可以少于至少一个小区的个数。这样可以节省第一配置消息的信令开销。在一种可能的设计中,公共信息字段的数量为1。也就是说,至少一个小区的配置信息的公共信息在第一配置消息中出现一次,即每个小区的公共信息可以被统一通知,每个小区特定的信息可以被各自通知,这样可以进一步节省第一配置消息的信令开销。这里的公共信息出现一次即为一个公共信息字段。例如,每个小区的公共信息占用5bit,第一配置消息中携带5个小区的配置信息,那么5个小区的配置信息中的公共信息占用25bit,但是如果公共信息在第一配置消息特定的比特位置只出现一次,那么可节省20bit的信令开销。如表1所示,表1示出了第一配置消息中携带的多个小区的配置信息。
表1第一配置消息的内容
从表1中可以看出,第一配置消息中包括小区1(Cell1)、小区2(Cell2)以及小区3(Cell3)等多个小区的公共信息以及每个小区特定的信息。每个小区特定的信息例如可以包括小区的索引(Cellindex)、PCI、载波频率(Frequency)以及该小区的无线资源配置(Cell-specific radio configurations)等。
上述公共信息包含的参数可以如表2所示。

动重传请求(Hybrid Automatic Repeat reQuest,HARQ)反馈信道配置,soundingRS-UL-ConfigCommon表示探测参考信号上行公共配置,uplinkPowerControlCommon表示上行功控公共配置,tdd-Config表示时分复用配置,mbsfn-SubframeConfigList表示多播同频网子帧配置,p-Max表示最大功率,antennaInfoCommon表示天线公共信息,ul-CyclicPrefixLength表示上行循环前缀长度,pdsch-ConfigDedicated表示物理下行共享信道专用配置,pusch-ConfigDedicated表示物理上行共享信道专用配置,uplinkPowerControlDedicated表示上行功控专用配置,tpc-PDCCH-ConfigPUSCH表示功控命令配置,cqi-ReportConfig表示信道质量指示上报配置,soundingRS-UL-ConfigDedicated表示探测参考信号上行专用配置,AntennaInfoDedicated表示天线专用信息。在另一种可能的设计中,若每个小区的配置信息包括该小区所属的一组小区的组的索引,则每组小区的配置信息包括该组小区的组的索引,以及该组小区中每个小区的PCI、载波频率以及无线资源配置中的至少一种。也就是说,第一配置消息中的小区可进行分组,每组小区对应一个组的索引。其中,分组的依据可以是基站基于小区部署或位置等决定,例如将小区覆盖范围较近的多个小区分为一组。
同样地,若任一组小区的配置信息中若存在公共信息,为了节省信令开销,该组小区的配置信息中的公共信息携带在第一配置消息的公共信息字段中。
402、终端设备接收基站发送的第一配置消息。
终端设备接收到基站发送的第一配置消息后,可存储第一配置消息中小区的配置信息。
这样一来,可在SCell的覆盖很小,随着终端设备移动,终端设备的SCell的质量快速发生变化,需要频繁地配置/去配置SCell时,本申请可通过第一配置消息携带多个小区的配置信息发送给终端设备,使得终端设备一次存储多个小区的配置信息,可降低发送配置消息配置/去配置小区的频率。
403、基站向终端设备发送第二配置消息,第二配置消息包括N个小区的索引或N组小区的索引,N为大于1的正整数,第二配置消息用于指示终端设备将至少一个小区中,N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的辅小区的配置信息。
当终端设备进入RRC连接态后,基站若确定终端设备需额外的无线资源,可向终端设备配置SCell小区。
在一个示例中,第二配置消息可以为RRC消息、或媒体介入控制信元MAC CE、或物理下行控制信道PDCCH信令。
可选的,该第二配置消息中还可以包括被配置为SCell的小区的特定无线资源配置,例如该特定无线资源配置指示终端设备更新某一小区的某一配置信息后再配置为终端设备的SCell。
这样,基站通过第二配置消息可携带配置为SCell的小区的索引和可选的特定无线资源配置,于是,在第二配置消息中可以携带配置为SCell的Cellindex,或配置为SCell的Cell的组的索引,不需要携带配置为SCell的小区除索引以外的其它配置
信息,可使得配置SCell的配置消息占用的比特大小大大降低,即信令开销降低,不需要为终端设备每次配置SCell时携带每个小区的所有配置信息。
404、终端设备接收基站发送的第二配置消息。
在一种可能的设计中,如图5所示,假设终端设备处于连接态时接收第一RRC消息,第一RRC消息中携带有至少一个小区的配置信息,之后基站向终端设备发送第二RRC消息,该第二RRC消息中包括N个小区的索引或N组小区的索引,指示终端设备将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息,终端设备接收到第二RRC消息后,查询小区的配置信息,将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息。而后,基站可以向终端设备发送MAC CE,该MAC CE用于激活SCell,作为SCell的小区就可以用于终端设备进行数据通信。
在另一种可能的设计中,如图6所示,假设终端设备处于连接态时接收第一RRC消息,第一RRC消息中携带有至少一个小区的配置信息,之后基站向终端设备发送第三RRC消息,该第三RRC消息中包括N个小区的索引或N组小区的索引,指示终端设备将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息,终端设备接收到第三RRC消息后,查询小区的配置信息,将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息。其中,第三RRC消息还可以用于激活该SCell,也就是上述第二配置消息还用于指示终端设备激活终端设备的辅小区。这样,终端设备在接收到第三RRC消息配置完SCell后可直接激活配置的SCell,基站也不需要再向终端设备发送用于激活SCell的消息,以节省信令开销。
再一种可能的设计中,如图7所示,假设终端设备处于连接态时接收第一RRC消息,第一RRC消息中携带有至少一个小区的配置信息,之后基站可向终端设备发送MAC CE或PDCCH,该MAC CE或PDCCH中包括N个小区的索引或N组小区的索引,指示终端设备将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息,终端设备在接收到MAC CE或PDCCH时,查询小区的配置信息,将N个小区的索引或N组小区的索引对应的小区的配置信息配置为终端设备的SCell的配置信息,并激活配置的SCell,激活后的SCell就可以用于终端设备进行数据通信。这样采用MAC CE或PDCCH携带待配置为SCell的索引,相对于采用RRC消息携带待配置为SCell的索引,MAC CE属于L2信令,PDCCH属于L1信令,可提升配置消息的发送速度,且信令开销更小。
需要说明的是,本申请实施例还可以应用于LTE中,还可以应用于LTE-新空中接口(New Radi0,NR)双连接中。在LTE-NR中,LTE可被部署为宏的主基站,NR可部署在小小区中,尤其在高频上。
还需要说明的是,在第二配置消息中携带一组或组小区的索引,而不需要携带多个个小区的索引,这样通过分组的方式也可以进一步减小第二配置消息的信令开销。
如果小区的配置信息发生变化,基站还可以通知终端设备更新小区的配置信息,因此,还方法实施例还可以包括:
405、基站向终端设备发送第三配置消息,第三配置消息为***消息或RRC消息,
第三配置消息包括更新的小区的配置信息。
例如该更新的小区的配置信息中可以包括终端设备已存储的小区的配置信息将要更新后的信息,也可以包括基站新添加的小区的配置信息,或者包括基站要删除的小区的配置信息的索引等。
或,基站需要更新终端设备保存的小区配置信息时,基站可以向终端设备发送第四配置消息,第四配置消息为RRC消息、或MAC CE、或PDCCH信令,第四配置消息包括更新的小区的配置信息,且第四配置消息用于指示终端设备根据更新的小区的配置信息替换上一次配置的辅小区的配置信息。也就是说,第四配置消息不仅用于指示终端设备更新已保存的小区的配置信息,且更新的小区的配置信息也同时被配置为终端设备的SCell的配置信息。
406、终端设备接收基站发送的第三配置消息。
当终端设备接收到的是第三配置消息,终端设备可根据第三配置消息中携带的信息更新本地已存储的小区的配置信息。
当终端设备接收到的是第四配置消息,终端设备可根据第四配置消息中携带的信息更新本地已存储的小区的配置信息,同时终端设备将更新的小区的配置信息替换已存储的SCell的配置信息。
在步骤403至404中,如果第二配置消息用于将小区的配置信息设置为SCell的配置信息时不兼有激活SCell的能力,例如第二配置消息为上述第一RRC消息时,那么还可以采用MAC CE来激活/去激活SCell,本申请实施例还可以降低激活SCell的MAC CE信令的开销。这种情况下,在步骤404之后,该方法还可以包括:
407、基站向终端设备发送第五配置消息,第五配置消息为RRC消息,第五配置消息包括终端设备的辅小区的分组信息,分组信息包括每组辅小区的组的标识以及每组辅小区包括的小区的索引。
也就是说,在终端设备将小区的配置信息配置为SCell的配置信息之后,被配置为SCell的小区可以进一步被分为一个或多个组,每组SCell包括至少一个SCell,且每组SCell被配置一个组的标识,每个组的标识对应的SCell组的分组信息包括该SCell组包括的至少一个SCell的索引。
例如基站配置的多个SCell被分组后包括SCell Group1、SCell Group2、……、SCell Group m,其中,SCell Group1可以包括索引为SCell1-1、SCell1-2、……、SCell1-n等多个SCell,SCell Group2可以包括索引为SCell2-1、SCell2-2、……、SCell2-n等多个SCell,SCell Group m可以包括索引为SCell1-1、SCell1-2、……、SCell1-n等多个SCell。
如何决定SCell的分组可以依赖与基站的实现,例如基站基于小区的部署、位置或测量等决定。
408、终端设备接收基站发送的第五配置消息。
终端设备可根据第五配置消息中的分组信息获知每组SCell所对应的至少一个SCell。
409、基站向终端设备发送第一MAC CE或第二MAC CE,第一MAC CE包括每组辅小区的组的标识对应的比特信息,第二MAC CE包括至少一组辅小区的组的标识以及至
少一组辅小区的组的标识对应的比特信息。
以基站向终端设备发送第一MAC CE为例,第一MAC CE中包括每组SCell的组的标识对应的比特信息。例如将终端设备的SCell分为8个组,以bitmap指示每组SCell被激活还是去激活。其中,任一组辅小区的组的标识对应的比特信息为第一比特值或第二比特值,第一比特值用于指示该组辅小区包括的每个辅小区激活,第二比特值用于指示该组辅小区包括的每个辅小区去激活。例如第一比特值为1,1表示激活相应的SCell组,第二比特值为0,0表示去激活相应的SCell组。假设8组SCell的组的标识为G0、G1、G2、G3、G4、G5、G6、G7以及G8,各组SCell的标识在MAC CE中的部分信令格式如表3所示。
表3
G7 | G6 | G5 | G4 | G3 | G2 | G1 | G0 |
例如表1中各组SCell的标识对应的bit的值如表2所示,说明G0、G2以及G5对应的SCell组包括的SCell被激活,G1、G3、G4、G6以及G7对应的SCell组的包括的SCell去激活。如果被分的SCell组少于8个组,则可以在表4中增加保留Rbit。
表4
0 | 0 | 1 | 0 | 0 | 1 | 0 | 1 |
以基站向终端设备发送第二MAC CE为例,第二MAC CE包括至少一组SCell的组的标识以及该至少一组SCell的组的标识对应的比特信息。例如表5为激活/去激活一组SCell时MAC CE中的部分信令格式,表6表示激活/去激活两组SCell时MAC CE中的部分信令格式。
表5
R | R | Ind | Group ID |
表6
表5和表6中,R表示保留bit,Ind对应的比特指示激活或去激活,与上述过程类似地,Ind对应的比特信息为第一比特值1时可以指示激活Ind对应的Group ID指示的SCell组,Ind对应的比特信息为第二比特值0时可以指示去激活Ind对应的Group ID指示的SCell组。
410、终端设备接收基站发送的第一MAC CE或第二MAC CE,并根据第一MAC CE或第二MAC CE激活或去激活辅小区。
即终端设备可根据第一MAC CE或第二MAC CE激活/去激活对应的一组SCell或多组SCell。相对于现有技术中发送的MAC CE激活/去激活SCell,需要携带每个激活/去激活的SCell的索引,本申请实施例可以在将SCell分组的情况下,通过第一MAC CE或第二MAC CE携带激活/去激活的SCell组的标识,不需要携带每个SCell的标识,可以减少MAC CE占用的比特数,降低MAC CE的信令开销。
