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的一部分实施例,而不是全部实施例。基于本发明中的实施例,本领域普通技术人员在没有作出创造性劳动的前提下所获得的所有其他实施例,都应属于本发明保护的范围。
应理解,本发明实施例的技术方案可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,简称“GSM”)系统、码分多址(Code Division Multiple Access,简称“CDMA”)系统、宽带码分多址(Wideband Code Division Multiple Access,简称“WCDMA”)系统、通用分组无线业务(General Packet Radio Service,简称“GPRS”)、长期演进(Long Term Evolution,简称“LTE”)系统、通用移动通信系统(Universal Mobile Telecommunication System,简称“UMTS”)、等目前的通信系统,以及,尤其应用于未来的5G系统。
本发明实施例中的终端设备也可以指用户设备(User Equipment,简称“UE”)、接入终端、用户单元、用户站、移动站、移动台、远方站、远程 终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,简称“SIP”)电话、无线本地环路(Wireless Local Loop,简称“WLL”)站、个人数字处理(Personal Digital Assistant,简称“PDA”)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备,未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network,简称“PLMN”)中的终端设备等。
本发明实施例中的网络设备可以是用于与终端设备通信的设备,该网络设备可以是GSM或CDMA中的基站(Base Transceiver Station,简称“”BTS),也可以是WCDMA系统中的基站(NodeB,简称“NB”),还可以是LTE系统中的演进型基站(Evolutional NodeB,简称“eNB或eNodeB”),还可以是云无线接入网络(Cloud Radio Access Network,简称“CRAN”)场景下的无线控制器,或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等。下面以基站为例进行描述。
对于现在LTE系统中的参考信号,例如小区特定的参考信号,小区可以使用1个、2个或4个小区特定的参考信号,分别对应使用1个、2个或4个天线端口。小区特定的参考信号只在天线端口0~3中的一个或几个中传输。小区特定的参考信号在每个下行子帧,整个下行带宽内的每个RB上都会发送。在多播广播单频网络(Multicast Broadcast Single Frequency Network,简称“MBSFN”)子帧上,小区特定的参考信号只能在该子帧的非MBSFN区域(non-MBSFN region)上传输。由于小区特定的参考信号是在全带宽发送,并且在每个下行子帧都要发送。从网络设备节能和避免小区间干扰的角度考虑,在将来的5G系统中,可以选择在特定的频域资源上发送参考信号,并且可以规律地或非规律性地在特定的时间点或时间段上发送参考信号。
应理解,本发明实施例中的参考信号,也可以称为参考信道等,本发明对此不做限定。参考信号在特定的资源位置上发送后,终端设备通过一定的方式获取该参考信号的资源位置,接收该参考信号并对该参考信号进行解调,从而利用该参考信号进行信道估计或信道探测。
图1是本发明一个应用场景的示意图。图1中的通信系统可以包括基站 10和终端设备20。基站10用于为终端设备20提供通信服务并接入核心网,终端设备20通过搜索基站10发送的同步信号、广播信号等而接入网络,从而进行与网络的通信。图1中所示出的箭头可以表示通过终端设备20与基站10之间的蜂窝链路进行的上/下行传输。本发明实施例通过在部分特定的资源位置上发送参考信号,可以实现网络设备的节能并避免小区间的干扰。
图2示出了根据本发明实施例的传输参考信号的方法的流程交互图。图2中示出了基站10和终端设备20,图2中由基站10执行的方法也可以由其他网络设备执行。如图2所示,该传输参考信号的具体流程包括:
201,基站10确定用于传输参考信号的目标资源。
其中,基站10确定用于传输参考信号的目标资源,也可以称基站10确定用于传输参考信道的目标资源。
具体地,基站10在向移动终端20发送参考信号之前,为该参考信号配置特定的资源位置,并在该特定的资源位置上向移动终端20发送该参考信号,由于只是在部分资源位置上发送参考信号而不必在全部下行子帧上和全带宽内发送,因此能够减少基站10的能耗,并且避免了小区之间的干扰。
其中,该目标资源为可用于传输该参考信号的传输资源中的部分资源,该目标资源包括频域资源、时域资源和空域资源中的至少一种。该空域资源可以是在多输入多输出(Multiple-Input Multiple-Output,简称“MIMO”)等天线技术中形成的多流数据的传输模式。该时域资源可以包括至少一个时间段和/或至少一个时间点,并且可选地,该至少一个时间段和/或至少一个时间点是按周期分布的。
应理解,这里基站10确定用于传输参考信号的目标资源,也可以说是基站10确定用于传输该参考信号对应的参考信道的目标资源,并且本发明实施例中基站10还可以为其他特定信号或特定信道确定用于传输的目标资源。传输该参考信号的资源可以包括频域资源、时域资源和空域资源中的至少一种。
具体地,基站10可以为该参考信号配置频域资源、时域资源和空域资源中的至少一种。在频域资源、时域资源和空域资源对应的三种资源项中,每一个资源项都是可选存在的,如果基站10没有为该参考信号配置某项资源,即该资源项空缺,那么可以表示该参考信号可以在该资源项表示的资源上任意发送,例如在该资源项对应的整个可用于参考信号传输的资源上都发 送该参考信号,或者可以按照协议中约定的特定资源位置上发送。
还应理解,基站10确定的用于传输该参考信号的资源,还可以是基站10根据协议规定获取的用于传输该参考信号的资源,本发明对此不作限定。
其中,该参考信号例如可以包括小区特定的参考信号CRS。
可选地,基站10确定用于传输该参考信号的目标资源,包括:
确定参考标识,该参考标识包括小区标识或波束标识;
根据该参考标识,以及该参考标识与资源标识之间的对应关系,确定用于传输该参考信号的目标资源,该资源标识与该目标资源一一对应。
具体而言,网络设备可以根据参考标识,以及该参考标识与资源标识之间的对应关系,确定该资源标识,并根据该资源标识确定与该资源标识一一对应的用于传输参考信号的目标资源。该资源标识与目标资源的对应关系,具体可以参见下面对表一至表四的描述。
可选地,该参考标识与该资源标识之间的对应关系可以包括i=mod(Cell ID,I)或i=mod(Beam ID,I),其中,该i表示该资源标识,该Cell ID表示该小区标识,该Beam ID表示该波束标识,该I表示最大资源标识数。
举例来说,假设小区标识Cell ID=7,最大的资源标识数I=5,那么可以计算出资源标识i=2,基站10应该在i=2对应的目标资源上向终端设备20发送参考信号。
又例如,假设波束标识Beam ID=11,最大的资源标识数I=5,那么可以计算出资源标识i=1,基站10应该在i=1对应的目标资源上向终端设备20发送参考信号。
应理解,这里的确定出的资源标识,可以是指示时域资源标识、频域资源标识和空域资源标识的组合资源标识,也可以是指示时域资源的时域资源标识,还可以是指示频域资源的频域资源标识或指示空域资源的空域资源标志。例如基站10可以根据小区标识确定时域资源标识,然后根据时域资源标识与频域资源标识或空域资源标识的关系,确定频域资源标识或空域资源标识。本发明对此不做任何限定。
202,基站10向终端设备20发送指示信息。
具体而言,该指示信息可以用于显式或隐式指示用于传输该参考信号的目标资源,以便于终端设备20根据该指示信息获取用于接收该参考信号的目标资源的位置。
例如,基站10可以向终端设备20发送指示信息,从而显式指示用于传输参考信号的目标资源的位置;基站10还可以向终端设备隐式地指示该目标资源的位置,通过向终端设备20指示该目标资源对应的资源标识,使得终端设备20获知接收该参考信号的目标资源。
可选地,基站10可以向终端设备20发送指示信息,该指示信息包括用于指示所述目标资源的资源指示信息。
该实施例中,基站10可以通过向终端设备发送直接指示用于传输该参考信号的目标资源的资源指示信息,使得终端设备20可以通过该资源指示信息直接获取用于传输该参考信号的目标资源。
可选地,基站10向终端设备发20送指示信息,该指示信息包括用于指示资源标识的标识指示信息,该资源标识与目标资源一一对应。
具体而言,用于传输该参考信号的目标资源和指示该目标资源的资源标识是一一对应的,如果知道该参考信号的资源标识,就能够根据该资源标识确定用于传输该参考信号的目标资源。因此,基站10可以通过向终端设备20发送与该目标资源对应的资源标识,以使得终端设备20获取用于传输参考信号的目标资源。
可选地,该资源标识可以包括以下标识中的至少一种:
用于指示该频域资源的频域资源标识、用于指示该时域资源和时域资源周期的时域资源标识、用于指示该空域资源的空域资源标识、和用于指示该频域资源、该时域资源和该空域资源中至少两种资源的组合资源标识。
具体而言,该资源标识中可以包括至少一中资源标识,该组合资源标识中可以包括频域资源、时域资源和空域资源中的至少两种资源位置的组合。例如,该资源标识中可以包括频域资源标识、时域资源标识和空域资源标识;或者包括同时指示该频域资源、该时域资源和该空域资源组合资源标识;或者包括空域资源标识,以及指示该频域资源和该时域资源的组合资源标识。
下面结合表一至表四,举例说明本发明实施例中的目标资源和资源标识之间的对应关系。表一是频域资源、时域资源和空域资源与组合资源标识的对应关系。
表一
资源标识 频域资源 时域资源 空域资源
0 Df1、Df3 Dt1(T1) L1

2 Df1、Df3 Dt1(T2) L2

I-1 Dfm Dtn(Tn) Lk
其中,表一中的组合标识可以包括0,1,2,3……I-1,其中I为自然数,每一个标识号对应特定的频域资源、时域资源和空域资源。
表一中的第二列表示频域资源,Dfi表示频域资源中的一个连续区间,即一个特定的频带范围,i为大于等于1小于等于m的整数,m为整个频域资源被划分成的子资源的总个数,例如m=5时表示整个频域资源被划分成5个子频域资源,每个子频域资源对应的频域资源位置各不相同。
表一中的第三列表示时域资源,时域资源中可以包括特定的时间段和/或特定的时间点,以及时域资源周期T。其中,Dti表示时域资源中的一个连续区间,即一个特定的时间段的标识,或者一个特定的时间点的标识,且i为大于等于1小于等于n的整数。n为固定时域资源被划分成的子资源的总个数。应理解,每个时域资源周期中可以包括按周期分布的至少一个时间段和/或至少一个时间点。
举例来说,例如,假设时域资源周期T1=10ms,n=10,时间点的标识Dti=2,这时基站10可以在每个10ms内的第2ms上发送参考信号;又假设时域资源周期T1=5ms,n=5,时间点的标识i=3,这时基站10可以在每个5ms内的第3ms上发送参考信号;又假设时域资源周期T2=14ms,n=2,该时间周期分为两个时间段,分别为时间段10(0~7ms)和时间段20(7~14ms),时间段的标识Dti=20,这时,基站10可以在每个14ms内的第7ms~第14ms上发送参考信号;又假设时域资源周期T2=10ms,n=3,该时间周期分为三个时间段,分别为时间段10(0~2ms)、时间段20(4~6ms)和时间段30(8~10ms),时间段的标识i=30,这时,基站10可以在每个10ms内的第8ms~第10ms上发送参考信号。特别地,T=10ms,n=10,也可以表示一个无线帧中包括的10个子帧(每个子帧1ms),Dti等于几就表示在该无线帧中对应的第几个子帧上发送参考信号。
其中,该时域资源周期的信息可以承载在时域资源标识的信息中,也可以是单独配置的或者协议中规定的。
表一中的第四列表示空域资源,该空域资源通过层(Laryer,简写为“L”)表示,Li表示第i个空域资源,i为大于等于1小于等于k的整数。k为整个空域资源被划分为的总层数,例如m=5时表示整个空域资源被划分成5层。
举例来说,与标识号0对应的频域资源包括Df1和Df3,与标识0对应的时域资源包括T1周期内的时间段Dt1,与标识0对应空域资源包括L1。当基站10确定了该参考信号的资源标识,就能够确定与该资源标识一一对应的目标资源,从而在该目标资源(频域资源、时域资源和空域资源)上向终端设备20发送参考信号,即在频带Df1和Df3,时间段Dt1和层L1上向终端设备发送参考信号。
除了上述的用一个特定的资源标识表示几种资源的组合,还可以用一个特定的资源标识表示其中的任意一种资源,例如频域资源、时域资源和空域资源分别对应各自的资源标识。表二、表三和表四分别是频域资源和频域资源标识的对应关系、时域资源和时域资源标识的对应关系、以及空域资源和空域资源标识的对应关系。

其中,If-1、It-1、Il-1分别表示频域资源标识的最大资源标识数、时域资源标识的最大资源标识数和空域资源标识的最大资源标识数。表二至表四中的符号的含义可以参考前述对表一的描述,为了简洁,这里不再赘述。
应理解,目标资源和资源标识的映射关系,可以是通过网络侧配置的,也可以是协议中预定义的。本发明对此不作限定。
上面描述的目标资源和资源标识的对应关系,仅仅是示例,该资源标识与目标资源的对应关系,还可以通过其他方式来确定。例如在201中,网络设备确定用于传输该参考信号的目标资源,可以是根据目标资源中的任意一种资源对应的资源标识确定该目标资源。
举例来说,基站10可以根据时域资源标识确定频域资源标识和空域资源标识,从而根据该时域资源标识、该频域资源标识和该空域资源标识确定该目标资源;或者基站10可以根据频域资源标识确定时域资源标识和空域资源标识,从而根据该时域资源标识、该频域资源标识和该空域资源标识确定该目标资源;或者基站10可以根据空域资源标识确定时域资源标识和频域资源标识,从而根据该时域资源标识、该频域资源标识和该空域资源标识确定该目标资源。
应理解,基站10也可以只确定两种资源标识,例如根据时域资源标识确定空域资源标识,而频域资源标识空缺,该空缺的资源项可以表示该参考信号可以在全带宽内发送或者在协议约定的频域资源位置上发送。本发明对此不做限定。
可选地,该资源标识包括该时域资源标识时,网络设备20确定用于传输该参考信号的目标资源,包括:
网络设备20根据以下对应关系中的任意一种,确定用于传输该参考信号的该频域资源:if=mod(RN,If)、if=mod(Pi,If)、if=mod(Dti,If)和if=mod(it,If);和/或
网络设备20根据以下对应关系中的任意一种,确定用于传输该参考信号的该空域资源:il=mod(RN,Il)、il=mod(Pi,Il)、il=mod(Dti,Il)和il=mod(it,Il)。
其中,RN表示该时域资源在该时域资源周期中的资源编号,Pi表示该时域资源周期的编号,Dti表示该时域资源在该时域资源周期中对应的时间段或时间点,it表示该时域资源标识,if表示该频域资源标识,il表示该空域资源标识,If表示最大频域资源标识数,Il表示最大空域资源标识数。
其中,该时域资源在时域资源周期中的资源编号RN,可以包括系统帧号(System Frame Number,简称“SFN”)、子帧号、时隙号等无线帧的编号。本发明对此不做限定。
举例来说,基站10向终端设备20发送的标识指示信息中可以包括时域资源标识,例如该时域资源标识可以为时域资源在时域资源周期中的资源编号。假设该资源编号RN为其所在的系统帧号且SFN=11,该标识指示信息包括时域资源标识但不包括频域资源标识,基站10可以根据if=mod(SFN,If)确定出频域资源标识。例如当最大频域资源标识数If=5时,频域资源标识if=1,基站10应该在SFN=11和if=1对应的频域资源上向终端设备20发送参考信号。
如果该标识指示信息包括时域资源标识但不包括空域资源标识,基站10可以根据il=mod(SFN,Il)确定出空域资源标识。例如当最大空域资源标识数Il=3时,空域资源标识il=2,基站10应该在SFN=11和il=2对应的空域资源上向终端设备20发送参考信号。
当然,如果该标识指示信息只包括时域资源标识而不包括频域资源标识和空域资源标识,基站10可以根据if=mod(SFN,If)和il=mod(SFN,Il)确定频域资源标识if和空域资源标识il
又例如,基站10可以根据if=mod(Pi,If)和il=mod(Pi,Il)确定频域资源标识和空域资源标识。假设时域资源所在的周期的编号Pi=12,当最大频域资源标识数If=5时,频域资源标识if=2,当最大空域资源标识数Il=3时,空 域资源标识il=0,基站10应该在Pi=12对应的时域资源周期、if=2对应的频域资源和il=0对应的空域资源上向终端设备20发送参考信号。
又例如,时域资源所在的某一周期内特定的时间点或时间段Dti=11,基站10可以根据if=mod(Dti,If)和il=mod(Dti,Il)确定频域资源标识和空域资源标识,当最大频域资源标识数If=5时,频域资源标识if=1,当最大空域资源标识数Il=3时,空域资源标识il=2,基站10应该在Dti=11对应的时域资源、if=1对应的频域资源和il=2对应的空域资源上向终端设备20发送参考信号。
又例如,资源标识中可以直接包括时域资源标识,假设时域资源标识it=13,基站10可以根据if=mod(it,If)和il=mod(it,Il)确定出频域资源标识和空域资源标识,当最大频域资源标识数If=5时,频域资源标识if=3,当最大空域资源标识数Il=3时,空域资源标识il=1,基站10应该在it=13对应的时域资源、if=3对应的频域资源和il=1对应的空域资源上向终端设备20发送参考信号。
可选地,该资源标识包括频域资源标识时,基站10确定用于传输所述参考信号的目标资源,包括:
根据it=mod(if,It)确定用于传输所述参考信号的所述时域资源;和/或
根据il=mod(if,Il)确定用于传输所述参考信号的所述空域资源。
其中,it表示时域资源标识,It表示最大时域资源标识数,if表示频域资源标识,Il表示最大空域资源标识数,il表示空域资源标识。
举例来说,基站10向终端设备20发送的标识指示信息中可以包括频域资源标识。如果标识指示信息中包括频域资源标识而没包括时域资源标识,基站10可以根据it=mod(if,It)确定时域资源标识;如果标识指示信息中包括频域资源标识而没包括空域资源标识,基站10可以根据il=mod(if,Il)确定空域资源标识;如果标识指示信息中包括频域资源标识而没包括时域资源标识和空域资源标识时,基站10可以根据it=mod(if,It)和根据il=mod(if,Il)同时确定时域资源标识和空域资源标识。假设频域资源标识if=13,基站10根据it=mod(if,It)和il=mod(if,Il)确定时域资源标识和空域资源标识,当最大时域资源标识数It=5时,时域资源标识it=3,当最大空域资源标识数Il=3时,空域资源标识il=1,基站10应该在it=3对应的时域资源、if=13对应的频域资源标识和il=1对应的空域资源上向终端设备20发送参考信号。
可选地,该资源标识还可以包括空域资源标识时,基站10确定用于传输所述参考信号的目标资源,包括:
根据it=mod(il,It)确定用于传输所述参考信号的所述时域资源;和/或
根据if=mod(il,If)确定用于传输所述参考信号的所述频域资源。
其中,it表示时域资源标识,It表示最大时域资源标识数,if表示频域资源标识,If表示最大频域资源标识数,il表示空域资源标识
举例来说,基站10向终端设备20发送的资源指示信息中还可以包括空域资源标识,而不包括频域资源标识和/或频域资源标识。假设空域资源标识il=13,基站10可以根据it=mod(il,It)或者if=mod(il,If),可以确定出时域资源标识和频域资源标识,当最大时域资源标识数Il=5时,时域资源标识it=3,当最大频域资源标识数If=3时,频域资源标识if=1,基站10在it=3对应的时域资源、if=1对应的频域资源和il=13对应的空域资源上向终端设备20发送参考信号。
应理解,上述的任一资源标识与其他资源标识之间的相应关系,可以是在协议中约定的,或者是基站10确定并通知给终端设备20的。
还应理解,上述的根据协议约定或者基站10确定的任一资源标识与其他资源标识之间的相应关系,也可以包括各个资源标识之间显式的对应关系。本发明对此不做限定。
可选地,基站10向终端设备20发送该指示信息,包括:
基站10向终端设备20发送承载在高层信令、物理层信令或者媒体介入控制MAC层通知中的该指示消息。
具体地,基站10向移动终端20发送高层信令,通过该高层信令中包括的资源指示信息或标识指示信息,显式或隐式指示用于传输该参考信号的目标资源,例如在主信息块中携带指示该目标资源的资源指示信息或指示资源标识的标识指示信息;或者在系统信息块中携带该资源指示信息或该标识指示信息;基站10还可以向移动终端20发送物理层信令,通过该物理层信令中包括的资源指示信息或标识指示信息,显式或隐式指示该目标资源,例如在物理层的控制信道中携带该资源指示信息或该标识指示信息,或者确定一条专用的物理信道用于发送该资源指示信息或该标识指示信息;另外基站10也可以向移动终端20发送媒体介入控制(Media Access Control,简称“MAC”)层通知,通过MAC层通知中包括的该资源指示信息或该标识指 示信息,通知终端设备20用于接收该参考信号的目标资源。
203,终端设备20确定用于传输该参考信号的目标资源。
其中,终端设备20确定用于传输参考信号的目标资源,也可以称终端设备20确定用于传输参考信道的目标资源。
具体地,终端设备20接收基站10发送的指示信息后,可以根据该指示信息直接获取参考信号的资源位置,或者根据指示信息获取资源标识,并根据该资源标识确定与其对应的目标资源的位置。终端设备20确定了用于传输该参考信号的目标资源后,就可以在该目标资源上接收基站10发送的参考信号。并通过信号解调、处理,从而利用该参考信号进行信道估计或信道探测。
应理解,终端设备20如果接收到的是指示目标资源的资源指示信息,就直接在该资源指示信息所指示的目标资源上接收基站10发送的参考信号;终端设备20如果接收到的是指示资源标识的标识指示信息,需要通过该标识指示信息中的资源标识,从而根据该资源标识确定目标资源,例如根据该资源标识以及该资源标识与其他资源标识之间的关系确定其他资源标识,从而获取该目标资源。
还应理解,终端设备20获取到资源标识后,需要根据资源标识与目标资源的对应关系,确定与该资源标识对应的目标资源。其中该资源标识与目标资源的对应关系,可以是终端设备20根据协议获取的,也可以是基站10发送给终端设备20的,例如通过广播的方式向覆盖范围内多个终端设备发送该对应关系的信息,或者只向终端设备20发送该对应关系的信息,例如可以是发送如表一至表四中的至少一种对应关系。
可选地,终端设备20可以根据以下对应关系中的任意一种,确定用于传输所述参考信号的频域资源:if=mod(RN,If)、if=mod(Pi,If)、if=mod(Dti,If)和if=mod(it,If);和/或根据以下对应关系中的任意一种,确定用于传输所述参考信号的所述空域资源:il=mod(RN,Il)、il=mod(Pi,Il)、il=mod(Dti,Il)和il=mod(it,Il)。
可选地,终端设备20可以根据it=mod(if,It)确定用于传输所述参考信号的所述时域资源;和/或根据il=mod(if,Il)确定用于传输所述参考信号的所述空域资源。
可选地,终端设备20可以根据it=mod(il,It)确定用于传输所述参考信号 的所述时域资源标识;和/或根据if=mod(il,If)确定用于传输所述参考信号的所述频域资源标识。
应注意,终端设备20根据资源标识确定该目标资源的过程,具体可以参考基站10确定目标资源的过程,为了简洁,这里不再赘述。
204,基站10在该目标资源上向终端设备20发送参考信号。
其中,基站10在该目标资源上向终端设备20发送参考信号,也可以称基站10在该目标资源上向终端设备20发送参考信道。
具体地,基站10确定了目标资源后,在该目标资源上向终端设备20发送该参考信号或者该参考信号对应的参考信道,相应地,终端设备20根据基站10发送的指示信息确定了目标资源后,在该目标资源上接收基站10发送的参考信号。
应理解,204也可以在202之前执行,即基站10先向终端设备20发送参考信号再发送指示信息,本发明对此不做限定。
可选地,如果该目标资源发生变更,该方法还可以包括205。
205,基站10向终端设备20发送寻呼消息。
其中,该寻呼消息可以包括:变更后的目标资源的信息或用于指示该目标资源变更的指示消息。
也就是说,该参考信号的目标资源可以是确定的,也可以是根据网络条件等能够随时进行调整的,当需要对该目标资源的位置进行变更时,基站10通过向终端设备20发送指示目标资源变更的寻呼消息。
该寻呼消息可以中可以直接携带资源配置信息,即变更后的目标资源的位置信息,当终端设备20接收到该寻呼消息后就直接在该寻呼消息携带的资源配置上接收参考信号。该寻呼消息中也可以携带用于指示该目标资源变更的指示消息,终端设备20接收到该寻呼消息后可以通过读取主信息块或者特定的系统信息块获取该目标资源。
可选地,基站10可以向终端设备20发送寻呼消息,包括:
基站10向终端设备20发送承载在高层信令、物理层信令或MAC层通知中的该寻呼消息。
