Description

一种发送小区配置信息的方法及装置 技术领域
本申请实施例涉及通信领域,尤其涉及一种发送小区配置信息的方法及装置。
背景技术
目前,在长期演进升级(Long Term Evolution-Advanced,LTE-A)系统中,可以通过载波聚合(Carrier Aggregation,CA)技术增加传输带宽,满足LTE-A系统规定的提升峰值速率和系统容量的要求。在基站对终端配置了载波聚合的情况下,由于每个载波单元(Component Carrier,CC)对应一个独立的小区(Cell),此时,基站需要为终端配置与进行载波聚合的载波数量相同的服务小区(Serving Cell),其包括一个主小区(Primary Cell,PCell)和多个辅小区(Secondary Cell,SCell)。若基站为终端配置一个服务小区的配置信息的大小为s,总共需要配置n个服务小区时,那么基站向终端发送的配置信令包括的配置信息的大小为n*s,此时配置信令的开销较大。而且,在终端移动的场景下,终端已配置的辅小区的信号强度可能无法满足为终端服务的要求,此时终端需要对辅小区进行频繁地重配置,这样配置信令的条数也会明显增加。因此,在终端配置了载波聚合情况下,进行小区配置时的配置信令的开销较大。

具体实施方式
在第三代无线通信技术(the third Generation Telecommunication,3G)的通信协议和第四代无线通信技术(the fourth Generation Telecommunication,4G)的通信协议中规定,终端与基站建立RRC连接过程中,RRC信令需要携带小区配置信息,基站为终端进行小区配置,使终端在小区上与基站进行初始连接建立过程,或开始连接重建立过程,该小区也可称为服务小区,详细过程可以参见3GPP的36.331的3.1节的详述,本申请实施例在此不再赘述。
随着无线通信技术的发展,在长期演进升级(Long Term Evolution-Advanced,LTE-A)系统中,可以通过载波聚合(Carrier Aggregation,CA)技术增加传输带宽,满足LTE-A系统规定的提升峰值速率和系统容量的要求。如图1所示,CA技术可以将2~5个载波单元聚合在一起,每个载波单元为20兆赫(Mega Hertz,MHz),来实现最大100MHz的传输带宽,有效提高上下行传输速率。
为了便于理解,下面对载波聚合的基本概念进行简单的阐述。载波单元可以分为主载波单元(primary CC)和辅载波单元(secondary CC)。如果按照终端与基站的传输方向的不同,载波单元还可以分为下行主载波单元(Downlink Primary Component Carrier,DL PCC),上行主载波单元(Uplink Primary Component Carrier,UL PCC)、下行辅载波单元(Downlink Secondary Component Carrier,DL SCC)和上行辅载波单 元(Uplink Secondary Component Carrier,UL SCC)。每个载波单元对应一个独立的小区,那么,工作在主载波单元上的小区可以称为主小区,工作在辅载波单元上的小区可以称为辅小区。主小区是终端初始接入时的小区,负责与终端之间的RRC通信,主小区是在连接建立(connection establishment)时确定的。辅小区是在初始安全激活流程(initial security activation procedure)之后,通过RRC连接重配置(RRC Connection Reconfiguration)消息添加/修改/释放的,用于提供额外的无线资源,详细过程可以参见3GPP的36.331的3.1节的详述,本申请实施例在此不再赘述。
处于RRC连接(RRC_CONNECTED)态的终端,如果没有配置CA,则只有一个服务小区,即主小区;如果配置了CA,则服务小区集合是由主小区和多个辅小区组成的。3GPP的36.331的6.4节中规定了最大辅小区(maxSCell-r10)个数,即配置了载波聚合的终端可以与1个主小区和最多4个辅小区相连。3GPP的36.331的6.4节中规定了服务小区集合包括的服务小区个数(maxServCell-r10),即终端配置的主小区和所有辅小区组成了该终端的服务小区集合,服务小区集合包括最多5个服务小区,其中,服务小区可以是主小区也可以是辅小区。
每个载波单元都有一个对应的索引,主载波单元(primary CC)索引固定为0,而每个终端的辅载波单元索引是通过终端特定的RRC信令发给终端的,详细解释可以参见3GPP的36.331的6.2.2节的辅小区索引(sCellIndex-r10)。终端聚合的载波单元通常来自同一个基站且这些载波单元是同步的。当配置了载波聚合的终端在所有的辅小区内使用相同的小区无线网络临时标识(Cell Radio Network Temporary Identifier,C-RNTI)。载波聚合是终端级的特性,不同的终端可能有不同的主小区以及辅小区。
由于基站为终端配置一个服务小区的配置信息的大小是随着配置信息的内容不同而不同的,即配置信息包括的内容多,则配置信息的字节就大,配置信息包括的内容少,则配置信息的字节就小。若基站为终端配置一个服务小区的配置信息的大小为s,现有技术中进行载波聚合的载波个数可以达到32个载波,则基站总共需要为终端配置32个服务小区,那么基站向终端发送的配置信令包括的配置信息的大小为32*s,此时,配置信令的开销较大。而且,在终端移动的场景下,终端已配置的辅小区的信号强度可能无法满足为终端服务的要求,此时终端需要对辅小区进行频繁地重配置,这样配置信令的条数也会明显增加。因此,在终端配置了载波聚合情况下,为了能够有效地减小进行小区配置时的配置信令的开销,本申请实施例提供一种发送小区配置信息的方法,其基本原理是:首先,网络设备确定至少一个小区组,然后,向终端发送RRC信令,其中,RRC信令包括至少一个小区组中每个小区组的小区组配置信息,至少一个小区组中每个小区组包括至少两个小区,终端接收到网络设备发送的RRC信令后,对至少一个小区组中每个小区组包括的每个小区进行配置,终端对至少一个小区组中每个小区组包括的每个小区进行配置,具体包括:终端根据所述小区组的小区组配置信息配置所述小区组包括的所述每个小区。从而,通过将需要配置的小区进行划分,得到至少一个小区组,每个小区组对应一个配置信息,因此,网络设备向终端发送的RRC信令包含了小区组的配置信息,小区组所包含的每个小区对应同一个配置信息,即所述小区组配置信息,使得终端可以根据小区组配置信息对小区组所包含的每个小区进行配置,相对于现有技术中网络设备向终端发送的RRC信令需要包括每个小区的 小区配置信息的情况下,能够有效地减小小区配置时的配置信令的开销。
下面将结合附图对本申请实施例的实施方式进行详细描述。
图2示出的是可以应用本申请实施例的系统架构的简化示意图。如图2所示,该系统架构可以包括:终端11和网络设备12,其中,实线表示主载波单元对应的主服务小区的范围,用于实现终端与网络设备之间的RRC连接和数据传输,虚线表示辅载波单元对应的辅服务小区的范围,用于实现终端与网络设备之间的数据传输。
其中,终端11可以是无线终端,无线终端可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(如,Radio Access Network,RAN)与一个或多个核心网或者互联网进行通信,无线终端可以是移动终端,如移动电话(或称为“蜂窝”电话)、计算机和数据卡,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。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(SIP)话机、无线本地环路(WLL,Wireless Local Loop)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station),移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、接入点(Access Point)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户站(Subscriber Station,SS)、用户端设备(Customer Premises Equipment,CPE)、用户设备(User Equipment,UE)等。作为一种实施例,图2中所示的终端可以为手机。
网络设备12可以是无线通信的基站(Base Station,BS)或基站控制器等。也可以称为无线接入点,收发站,中继站,小区,发送接收点(Transmit and Receive Port,TRP)等等。具体的,网络设备12是一种部署在无线接入网中用以为终端11提供无线通信功能的装置,其主要功能包括如下一个或多个功能:进行无线资源的管理、互联网协议(Internet Protocol,IP)头的压缩及用户数据流的加密、用户设备附着时进行移动管理实体(Mobility Management Entity,MME)的选择、路由用户面数据至服务网关(Service Gateway,SGW)、寻呼消息的组织和发送、广播消息的组织和发送、以移动性或调度为目的的测量及测量报告的配置等等。网络设备12可以包括各种形式的蜂窝基站、家庭基站、小区、无线传输点、宏基站、微基站、中继站、无线接入点等等。在采用不同的无线接入技术的系统中,具备基站功能的设备的名称可能会有所不同,例如,在3G系统中,称为基站(Node B),在长期演进(Long Term Evolution,LTE)系统中,称为演进型基站(evolved NodeB,eNB或eNodeB),在第五代移动通信技术(the fifth Generation Telecommunication,5G)系统中,称为gNB等等,在无线本地接入系统中,称为接入点(Access Ponit)。
需要说明的是,对于5G或新型无线接入网络(New Radio Access Network,NR)系统,在一个NR基站(NR-NB)下,可能存在一个或多个发送接收点(Transmission Reception Point,TRP),所有的TRP属于同一个小区,其中,每个TRP和终端都可以使用本申请实施例所述的测量上报方法。在另一种场景下,网络设备12还可以分为 中心单元(Central Unit,CU)和分布单元(Dsitribute Unit,DU),在一个CU下,可以存在多个DU,其中,每个DU和终端都可以使用本申请实施例所述的测量上报方法。CU-DU分离场景和多TRP场景的区别在于,TRP只是一个射频单元或一个天线设备,而DU中可以实现协议栈功能,例如DU中可以实现物理层功能。
随着通信技术的演进,网络设备的名称可能会变化。此外,在其它可能的情况下,网络设备12可以是其它为终端11提供无线通信功能的装置。为方便描述,本申请实施例中,为终端11提供无线通信功能的装置称为网络设备12。

图5为本申请实施例提供的一种发送和接收小区配置信息的方法流程图,如图5所示,该方法可以包括:
401、网络设备确定至少一个小区组。
网络设备可以对多个小区进行分组得到至少一个小区组。示例的,网络设备可以根据网络设备和终端两端都已配置的一些分组信息来确定至少一个小区组,具体的可以有以下实现方式:
方式一、由于网络设备预先配置有PUCCH组的分组信息,即PUCCH组包括主PUCCH组或辅PUCCH组,主PUCCH组是指包括主小区的小区组,辅PUCCH组是指包括多个辅小区的小区组。发送主PUCCH组的信令与主小区的PUCCH相关联。比如,在主小区上的PUCCH上发送包括主PUCCH组的信令。发送辅PUCCH组的信令与辅小区的PUCCH相关联。比如,在辅小区上的PUCCH上发送包括辅PUCCH组的信令。因此,网络设备可以根据PUCCH组对多个小区进行分组,将主小区划分到主PUCCH组,该主PUCCH组还可以包括其他辅小区;将剩余的辅小区划分到辅PUCCH组。
方式二、终端针对CA有单独的时间提前(Time Advance,TA)能力,可以同时在对应多个服务小区的载波上使用相同的TA进行接收或发送,多个服务小区被分到一个TAG里;或者,可以同时在对应多个服务小区的载波上使用多个TA进行接收或发送,多个服务小区被分到多个TAG里。TAG包含的是终端以相同的TA在对应多个服务小区的载波上使用相同TA进行接收或发送的小区组。TAG也可以称为上行同步组。因此,网络设备可以根据TAG对多个小区进行分组,来得到至少一个小区组。
方式三、网络设备根据一物理特性对多个小区进行分组,得到至少一个小区组。
示例的,在非授权频段中使用LTE技术,基于载波聚合的架构,由授权载波作为主小区的载波,授权载波或非授权载波作为辅小区的载波。辅小区对应的载波可以为非授权载波或者授权载波。假设辅小区对应的载波可以为授权载波,那么在配置的时候会在辅小区的配置属性上标示出具体的LAA属性,即为授权载波。这样,就可以根据包含LAA属性的辅小区划分到授权载波辅小区组,没有包含LAA属性的辅小区划分到非LAA辅小区组。因此,网络设备根据多个小区对应的载波的载波特性对多个小区进行分组,确定至少一个小区组。
应理解,通信物理特性可以被称为Numerology。该通信物理特性对应通信系统中所采用的不同的参数的集合。不同的Numerology对应的参数可以不同。包括而不限定的,该通信物理特性为以下参数之一或者任意的组合的集合:子载波宽度、循环前缀(Cyclic Prefix,简称“CP”)长度、传输时间间隔(Transmission Time Interval,简称“TTI”)、符号(Symbol)个数、资源块(Resource Block,简称“RB”)位置、时隙长度和帧格式等。作为举例,读者可以从www.3gpp.org获得提案R1-1613779或者R2-168012来理解该通信物理特性Numerology的含义,这些提案的内容包含在本申请实施例的内容中。因为3GPP标准组织的公正性和公开性,这里不再赘述。
需要说明的是,每个小区组应当包括至少两个小区,这样才能体现多个小区对应 了同一个配置信息,即小区组配置信息,那么对于不同的小区,网络设备向终端发送配置信息时,只需要发送同一个小区组配置信息即可,无需对每个小区发送一个小区配置信息。
402、网络设备向终端发送RRC信令。
网络设备确定至少一个小区组之后,向终端发送RRC信令,该RRC信令包括网络设备确定的至少一个小区组中每个小区组的小区组配置信息。示例的,小区组配置信息包括随机接入信道(Random Access Channel,RACH)信息、物理随机接入信道(Physical Random Access Channel,PRACH)、物理下行共享信道(Physical Downlink Shared Channel,PDSCH)、物理上行共享信道(Physical Uplink Shared Channel,PUSCH)、物理混合自动重传指示信道(Physical Hybrid ARQ Indicator Channel,PHICH)、PUCCH、小区上行带宽信息、上行探测信号信息、支持的天线层数、跨载波调度信息、CSI RS、ePDCCH信息、上行共享信道信息针对终端的功控信息和CQI上报信息中的至少一个。需要说明的是,本申请实施例对小区组配置信息具体包括的内容不做限定,实际应用中还可以包括其他的信息,这里只是举例说明。
需要说明的是,RRC信令还可以包括划分规则信息,以便于终端获知网络设备是如何划分小区的。在网络设备根据物理上行控制信道组或上行时间提前组对多个小区进行分组,得到至少一个小区组的情况下,网络设备向终端发送的RRC信令还包括至少一个小区组中每个小区组的小区组信息,小区组信息包含小区组所包含的至少两个小区的小区标识信息。小区标识信息可以是小区的物理层ID,例如物理小区标识(Physical Cell Identifier,PCI),也可以是小区ID,例如,小区索引,本申请实施例对此不作限定,只要是能区别不同的小区即可。在网络设备根据物理特性确定至少一个小区组时,由于终端和网络设备采用相同的方式确定,因此,网络设备向终端发送的RRC信令无需包括小区组信息。
403、终端接收网络设备发送的RRC信令。
网络设备向终端发送RRC信令之后,终端接收网络设备发送的RRC信令。
404、终端根据至少一个小区组中每个小区组的小区组配置信息对至少一个小区组中每个小区组包括的每个小区进行配置。
终端接收到网络设备发送的RRC信令之后,终端对至少一个小区组中每个小区组包括的每个小区进行配置,具体包括:终端根据小区组的小区组配置信息配置小区组包括的所述每个小区。
从而,本申请实施例所述的发送和接收小区配置信息的方法,通过将需要配置的小区进行划分,得到至少一个小区组,每个小区组对应一个配置信息,因此,网络设备向终端发送的RRC信令包含了小区组的配置信息,小区组所包含的每个小区对应同一个配置信息,即所述小区组配置信息,使得终端可以根据小区组配置信息对小区组所包含的每个小区进行配置,相对于现有技术中网络设备向终端发送的RRC信令需要包括每个小区的小区配置信息的情况下,能够有效地减小小区配置时的配置信令的开销。
图6为本申请实施例提供的一种发送和接收小区配置信息的方法流程图,如图6所示,该方法可以包括:
501、网络设备向终端发送基准小区的配置信息。
基准小区的配置信息包含用于配置基准小区的信息。基准小区为主小区,或者,基准小区为物理上行控制信息组中的物理上行控制信道小区,或者,基准小区为辅小区中的任一个。需要说明的是,基准小区的配置信息可以通过RRC重配置消息发送,也可以通过切换命令发送,本申请实施例对此不作限定。
502、终端接收网络设备发送的基准小区的配置信息。
网络设备向终端发送基准小区的配置信息之后,终端接收网络设备发送的基准小区的配置信息。终端可以根据基准小区的配置信息配置基准小区和也可以不配置基准小区,具体的,可以根据网络设备的通知执行。
503、网络设备向终端发送至少一个待配置小区中每个待配置小区的配置信息。
其中,待配置小区的配置信息包括第一标识,第一标识用于指示待配置小区的配置信息是否是基于基准小区的配置信息配置,若第一标识指示待配置小区的配置信息不是基于基准小区的配置信息配置,进一步的,待配置小区的配置信息还包括至少一个第二标识,至少一个第二标识用于指示待配置小区的配置信息中至少一个参数是否是基于基准小区的配置信息包括的参数配置,若第二标识指示待配置小区的配置信息中与第二标识对应的参数不是基于基准小区的配置信息包括的参数配置,则待配置小区的配置信息还包括与第二标识对应的参数。
示例的,在待配置小区的配置信息中设置第一标识和第二标识可以有以下实现方式。
在一种可能的实现方式中,如图7中的(a)所示,第一标识和第二标识可以设置在待配置小区的配置信息的包头中,其中,包头可是RRC信令的信息单元(Information Element,IE),可选的,可以是RRC信令的起始信息单元,即第一标识和第二标识可以设置在RRC信令的信息单元中。假设第一标识设置为1时,指示待配置小区的配置信息是基于基准小区的配置信息配置,此时,待配置小区的配置信息的包头中不包括第二标识,待配置小区的配置信息中信息单元也不包括具体的参数,终端接收到该待配置小区的配置信息后,识别包头中的第一标识后,可知可以根据基准小区的配置信息来配置待配置小区。假设第一标识设置为0时,指示待配置小区的配置信息不是基于基准小区的配置信息配置,此时,进一步的待配置小区的配置信息的包头中还包括一个第二标识,第二标识可以是用1和0组成的字符串,字符串从左至右的每一比特位依次对应待配置小区的配置信息中从左至右的参数。另外,第二标识对应的参数,可以是一个参数位于一个信息单元中,也可以是多个参数位于同一个信息单元中。
对于一个参数位于一个信息单元中,如图7中的(a)所示,第二标识的第一比特位对应信息单元1,第二标识的第二比特位对应信息单元2,第二标识的第三比特位对应信息单元3。假设第二标识的第一比特位设置为1时,信息单元1不包括参数,指示终端基于基准小区的配置信息中与第二标识对应的参数配置待配置小区,即基准小区的配置信息中信息单元1包括的参数配置待配置小区,假设第二标识的第二比特位设置为0时,信息单元2包括参数,指示终端按照待配置小区的配置信息中与第二标识对应的参数配置待配置小区,即待配置小区的配置信息中信息单元2包括的参数配置待配置小区,假设第二标识的第三比特位设置为1时,信息单元3不包括参数,指 示终端基于基准小区的配置信息中与第二标识对应的参数配置待配置小区,即基准小区的配置信息中信息单元3包括的参数配置待配置小区。
对于多个参数位于同一个信息单元中,需要说明的是,待配置小区的配置信息包括的第二标识的每个比特位的个数需要与基准小区的配置信息包括的参数的个数相同,且第二标识的字符串从左至右的每一比特位指示的参数位置也应依次与基准小区的配置信息中从左至右的参数位置相同。如图7中的(b)所示,第二标识的第一比特位、第二比特位和第三比特位分别对应待配置小区的配置信息的信息单元1包括的参数1、参数2和参数3,第二标识的第四比特位对应待配置小区的配置信息的信息单元2包括的参数4。假设第二标识的第一比特位设置为1时,待配置小区的配置信息的信息单元1不包括参数1,指示终端基于基准小区的配置信息中与第二标识对应的参数配置待配置小区,即基准小区的配置信息中信息单元1包括的参数1配置待配置小区,假设第二标识的第二比特位设置为1时,待配置小区的配置信息的信息单元1不包括参数2,指示终端基于基准小区的配置信息中与第二标识对应的参数配置待配置小区,即基准小区的配置信息中信息单元1包括的参数2配置待配置小区,假设第二标识的第三比特位设置为0时,待配置小区的配置信息的信息单元1包括参数3,指示终端根据待配置小区的配置信息中与第二标识对应的参数配置待配置小区,即待配置小区的配置信息中信息单元1包括的参数3配置待配置小区,假设第二标识的第四比特位设置为0时,待配置小区的配置信息的信息单元2包括参数4,指示终端根据待配置小区的配置信息中与第二标识对应的参数配置待配置小区,即待配置小区的配置信息中信息单元2包括的参数4配置待配置小区。
在另一种可能的实现方式中,第一标识可以设置在待配置小区的配置信息的包头中,即待配置小区的配置信息的包头中可以只包括第一标识,而第二标识可以分别设置在待配置小区的配置信息中的信息单元中。假设第一标识设置为1时,指示待配置小区的配置信息是基于基准小区的配置信息配置,此时,待配置小区的配置信息的每个信息单元中不包括第二标识,待配置小区的配置信息中信息单元也不包括具体的参数,终端接收到该待配置小区的配置信息后,识别包头中的第一标识后,可知可以根据基准小区的配置信息来配置待配置小区。如图7中的(c)所示,假设第一标识设置为0时,指示待配置小区的配置信息不是基于基准小区的配置信息配置,此时,进一步的待配置小区的配置信息的每个信息单元中还包括一个第二标识。假设待配置小区的配置信息的信息单元1包括的第二标识设置为1时,信息单元1不包括参数,指示终端基于基准小区的配置信息中与第二标识对应的参数配置待配置小区,即基准小区的配置信息中信息单元1包括的参数配置待配置小区,假设待配置小区的配置信息的信息单元2包括的第二标识设置为0时,信息单元2包括参数,指示终端按照待配置小区的配置信息中与第二标识对应的参数,即待配置小区的配置信息中信息单元2包括的参数配置待配置小区,假设待配置小区的配置信息的信息单元3包括的第二标识设置为1时,信息单元3不包括参数,指示终端基于基准小区的配置信息中与第二标识对应参数配置待配置小区,即基准小区的配置信息中信息单元3包括的参数配置待配置小区。
另外,在待配置小区的配置信息的信息单元中也可以只设置第二标识,只根据第 二标识在待配置小区的配置信息的信息单元中携带参数。例如,待配置小区的配置信息的第i信息单元中的第二标识设置为1时,指示终端基于基准小区的配置信息的第i信息单元包括的参数配置,此时,待配置小区的配置信息的第i信息单元中不包括具体的参数。若待配置小区的配置信息的第i信息单元中的第二标识设置为0时,指示终端基于待配置小区的配置信息的第i信息单元包括的参数配置,待配置小区的配置信息的第i信息单元包括具体的参数。
需要说明的是,待配置小区的配置信息还包含待配置小区的小区标识信息。当基准小区为辅小区中的一个时,网络设备向终端发送基准小区的标识信息。例如,小区标识信息可以是小区的物理层ID,也可以是小区ID,例如,小区索引,本申请实施例对此不作限定,只要是能区别不同的小区即可。
504、终端接收网络设备发送的至少一个待配置小区中每个待配置小区的配置信息。
网络设备向终端发送至少一个待配置小区中每个待配置小区的配置信息之后,终端接收网络设备发送的至少一个待配置小区中每个待配置小区的配置信息。
505、终端根据待配置小区的配置信息配置待配置小区。
终端接收网络设备发送的至少一个待配置小区中每个待配置小区的配置信息之后,终端根据待配置小区的配置信息配置所述待配置小区的配置信息对应的待配置小区。
首先,终端识别第一标识,若第一标识指示待配置小区的配置信息是基于基准小区的配置信息配置,则终端按照基准小区的配置信息配置待配置小区。若第一标识指示待配置小区的配置信息不是基于基准小区的配置信息配置,可以理解为,待配置小区的配置信息与基准小区的配置信息配置不是完全相同的,即待配置小区的配置信息与基准小区的配置信息配置可以完全不同,也可以部分不同。
在待配置小区的配置信息不是基于基准小区的配置信息配置的情况下,终端可以识别第二标识,若第二标识指示与第二标识对应的参数不是基于基准小区的配置信息包括的参数配置,则终端根据待配置小区的配置信息中与第二标识对应的参数配置待配置小区;若第二标识指示与第二标识对应的参数是基于基准小区的配置信息包括的参数配置,则终端根据基准小区的配置信息中与第二标识对应的参数配置待配置小区。当然,这里所述的第一标识和第二标识的设置方式可以是图7(a)至图7(c)所示的方式。
示例的,如图8所示,终端配置待配置小区示意图。假设图8中的小区1为基准小区,基准小区的配置信息包括参数1、参数2和参数3,在网络设备向终端发送小区2的配置信息前,将小区2的配置信息与小区1的配置信息进行比较,可知,小区2的参数1与小区1的参数1完全相同,小区2的参数2’与小区1的参数2不相同,小区2的参数3’与小区1的参数3不相同,则网络设备将小区2的配置信息包括的第一标识可以设置为0,小区2的参数1对应的第二标识设置为1,小区2的参数2对应的第二标识设置为0,小区2的参数3对应的第二标识设置为0,网络设备向终端发送的小区2的配置信息不包括小区2的参数1,需要包括小区2的参数2’和参数3’。终端接收到网络设备发送的小区2的配置信息后,终端识别第一标识为0,此时,终端获知小区2的配置信息不是基于基准小区的配置信息配置的,终端再识别小区2的参数1对应的第二标识设为1,此时终端收到包括小区2的参数1的信息单元为空, 未收到任何信息,终端根据基准小区的配置信息中与第二标识对应的参数;终端再识别小区2的参数2’对应的第二标识为0,此时终端收到小区2的参数2’,配置小区2的参数2’;终端再识别小区2的参数3对应的第二标识为0,此时终端收到小区2的参数3’,配置小区2的参数3’。同理,在网络设备向终端发送小区3的配置信息前,将小区3的配置信息与小区1的配置信息进行比较,可知,小区3的参数1与小区1的参数1完全相同,小区3的参数2与小区1的参数2完全相同,小区3的参数3与小区1的参数3完全相同,则网络设备将小区3的配置信息包括的第一标识可以设置为1,小区3的配置信息不包括第二标识,网络设备向终端发送的小区3的配置信息不包括任何参数。终端接收到网络设备发送的小区3的配置信息后,终端识别第一标识为1,此时,终端获知小区3的配置信息是基于基准小区的配置信息配置的,终端直接根据基准小区的配置信息配置小区3。
需要说明的是,相同的参数可以是系统带宽、PHICH信息、物理下行控制信道(Physical Downlink Control Channel,PDCCH)信息和numerology信息等,不同的参数可以是功控参数、天线参数和中心频率信息参数等。
从而,本申请实施例所述的发送小区配置信息的方法,网络设备通过在待配置小区的配置信息中设置第一标识,来指示待配置小区的配置信息包括的参数与基准小区的配置信息包括的参数是否相同,在待配置小区的配置信息包括的参数与基准小区的配置信息包括的参数相同的情况下,通过减少向终端发送的配置信令包括的相同参数,从而,减小了进行小区配置时的配置信令的开销。
