Description
本公开涉及通信技术领域,尤其涉及一种传输MTC系统信息的方法、装置、基站及终端。
MTC(Machine Type Communication,机器类通信)是指无人为干涉的机器之间的通信,广泛用于智慧城市,例如抄表;智慧农业,例如温度湿度等信息的采集;智慧交通例如共享单车等诸多领域。传统的MTC物理下行控制信道PDCCH是部署在4G LTE(Long Term Evoluttion,长期演进)频谱内、和LTE用户共用频率资源和部分信道。
相关技术中,MTC系统依附于4G LTE系统部署资源,在LTE系统广播系统信息如主信息块MIB(Master Information Block)的时间周期如40ms内,并不在预设子帧的控制信道区域即一个子帧前3个OFDM符号对应区域和CRS(cell reference signal小区参考信号)占用的物理资源位置处映射MTC系统的物理广播信道PBCH资源。
随着通信技术的发展,移动通信网络逐渐向5G NR(New Radio)网络演进,LTE系统将逐渐退出移动蜂窝网络,届时LTE系统的频谱资源将被重耕为5G NR频谱资源。由于MTC系统的生存周期较长,可以长达十几年,在LTE系统退出移动蜂窝网络之后,MTC系统可能依然存在,因此需要独立部署MTC系统的PBCH资源,以承载MTC系统的系统信息如MIB。若仍按照相关技术部署MTC系统的PBCH资源,将导致原LTE系统的控制信道资源被闲置,造成资源浪费。

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。

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:5G网络中的基站和终端,其中,基站可以是设置有大规模天线阵列的基站、子基站等。终端可以是传输机器类通信业务的设备,简称MTC设备,如智能电表、共享单车等。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。
本公开应用场景为:MTC系统不依附于原4G LTE系统而进行独立部署,例如原4G LTE系统的频谱资源被重耕为5G NR系统的频谱资源。
在原4G LTE系统中,MTC设备需要和LTE用户共用频谱资源和信道,即MTC系统依附于原4G LTE系统。其中,由于MTC业务的窄带传输特性,基站为MTC系统进 行资源映射时,不在已有控制区域(Control Region)即一个子帧的前3个OFDM符号所对应的时频区域内映射物理资源,而是在子帧的数据区域(Data Region)即后11个OFDM符号所对应的时频区域内为MTC系统映射物理资源。
相应的,基站为MTC系统在预设子帧中进行物理广播信道PBCH资源映射时,也不在上述预设子帧的控制区域映射MPBCH资源,本公开中,将MTC系统的PBCH资源简称为MPBCH资源。上述预设子帧包括:MTC FDD(Frequency Division Duplexing,频分双工)系统中第0号子帧和第9号子帧;以及,MTC TDD(Time Division Duplexing,时分双工)系统中第0号子帧和第5号子帧。上述MPBCH资源用于承载MTC系统的基本系统信息如主信息块MIB(Master Information Block)。
示例性的,参见图1-1所示的LTE系统中MTC FDD normal CP模式下MPBCH资源的映射示意图。在依附于原LTE系统的MTC系统中,当系统采用MTC FDD normal CP模式进行信息传输时,基站会在一个时长为40ms的广播周期内,通过第0号子帧和第9号子帧中部署的MPBCH资源,重复广播预设MTC系统信息如MIB信息,其中,图中的R0表示在一个广播周期内首次广播;R1、R2、R3、R4分别表示第一次、第二次、第三次、第四次重复广播。PSS/SSS分别表示主辅同步信号,PSS的全称是Primary Synchronization Signal,即主同步信号;SSS的全称是Secondary Synchronization Signal,即辅同步信号。
在LTE系统退出移动蜂窝网络后,原LTE系统中预设子帧的控制区域即前3个OFDM符号对应的时频区域将被空出,成为空白资源。如上示例,在LTE系统退出移动蜂窝网络后,图1-1所示的第0号子帧和第9号子帧的控制区域将被空出,成为空白资源,如图1-2所示。
基于此,本公开提供了一种传输MTC系统信息的方法,在基站为MTC系统独立部署MPBCH资源时,可以利用原LTE系统中预设子帧的控制区域资源传输MTC系统的预设系统信息如MIB信息,提高MTC系统信息的传输效率。
参见图2根据一示例性实施例示出的一种传输MTC系统信息的方法流程图,应用于基站中,所述方法可以包括以下步骤:
在步骤11中,确定小区内MTC设备的信息检测能力;
其中,一个MTC设备的信息检测能力,用于表示该MTC设备是否支持从目标资源区域搜索预设MTC系统信息如MIB信息。
上述目标资源区域的时频范围为:时域上等于原LTE系统预设子帧的控制区域对应的时间区域;频域上等于原LTE系统中预设MTC系统信息所占的频率资源区 域。其中,上述预设MTC系统信息包括:使MTC设备接入所述基站小区所需的信息,如MIB信息。MTC设备在接收到基站下发的所述预设MTC系统信息后,可以接入基站所覆盖的小区。
相应的,目标资源区域的频率区域可以是原LTE系统中MPBCH资源映射区域所占的频率资源区域。
仍以MTC FDD normal CP模式为例,原LTE系统中MPBCH资源的映射区域为第0号和第9号子帧的预设6个PRB对的数据区域所占的时频区域;其中,一个子帧的数据区域是指一个子帧的后11个OFDM符号对应的时频区域。一个PRB(physical resource block,物理资源块)的时频范围是:时域上为一个时隙slot,即0.5ms,其中,一个slot包括7个OFDM符号symbol;频域上包括12个连续的子载波,若一个子载波的频率间隔是15KHz,则一个PRB的频率范围是180KHz。一个PRB对在时域上占用2个slot,即1ms;在频域上包括12个子载波。
本公开涉及两类MTC设备,其中一类MTC设备不支持从目标资源区域搜索预设MTC系统信息,本公开中,可以称之为第一类MTC设备。该第一MTC设备可以是沿用原LTE系统传输协议的MTC设备,比如现有的Rel.13-Rel.15终端。另一类MTC设备可以支持从目标资源区域搜索预设MTC系统信息,本公开中,可以称之为第二类MTC设备。
关于基站如何确定MTC设备的信息检测能力,在一实施例中,基站可以根据运营商的部署信息,确定当前小区内各MTC设备的信息检测能力。
例如,基站根据预先获取的运营商部署信息,获知该小区内运营商只部署了release 13的MTC设备,可以确定当前小区内的MTC设备均属于第一类MTC设备。
在本公开另一实施例中,MTC设备接入基站小区后,基站还可以通过MTC设备上报的设备能力信息,确定各个MTC设备的信息检测能力。
参见图3根据一示例性实施例示出的另一种传输MTC系统信息的方法流程图,上述步骤11可以包括:
在步骤111中,获取每个所述MTC设备上报的设备能力信息;
本公开中,在MTC设备接入小区后,比如初次接入小区网络后,基站可以要求接入小区网络的MTC设备上报设备能力信息,即MTC设备被动上报设备能力信息。或者,MTC设备在预设触发条件下,比如接入该基站覆盖的小区网络时,主动向基站上报设备能力信息。该设备能力信息至少包括:表示MTC设备上述信息检测能力的信息。
在步骤112中,根据所述设备能力信息确定所述MTC设备的信息检测能力。
在本公开一实施例中,上述设备能力信息可以包括:用于表示所述信息检测能力的预设指示值。则上述步骤112具体为:根据所述预设指示值确定所述MTC设备的信息检测能力。
在一实施例中,可以采用第一指示值表示MTC设备属于第一类MTC设备;采用第二指示值表示MTC设备属于第二类MTC设备。
假设协议规定:利用承载上述设备能力信息的指定字段中的一个bit位,来表示MTC设备的上述信息检测能力。例如,上述第一指示值是0,上述第二指示值是1。
则上述步骤112的具体实施过程为:若基站检测到一个MTC设备比如UE1上报的设备能力信息中,上述预设bit位被置为0,则确定UE1不支持从所述目标资源区域搜索预设MTC系统信息,即确定UE1属于第一类MTC设备。反之,若上述预设bit位被置为1,则确定UE1支持从所述目标资源区域搜索预设MTC系统信息,即确定UE1属于第二类MTC设备。
在步骤12中,根据所述信息检测能力和预设资源映射方式,在所述预设子帧对应的时频区域映射目标物理资源,所述目标物理资源用于承载所述预设MTC系统信息;
本公开中,上述目标物理资源为承载预设MTC系统信息的资源,若上述预设MTC系统信息为MTC系统的MIB信息,则上述目标物理资源为MTC系统的PBCH资源,简称为MPBCH资源。以下示例将目标物理资源是MPBCH资源为例,进行详细说明。
根据小区内各MTC设备的信息检测能力不同,基站可以采用以下两种映射方式在预设子帧对应的时频区域内映射MPBCH资源:
第一映射方式,与原LTE系统一致,在原MPBCH资源映射区域中映射MPBCH资源。上述原MPBCH资源映射区域可以参见图1-1。
第二映射方式,在预设子帧的有效区域映射MPBCH资源,其中,上述有效区域是指预设子帧中除去CRS(cell reference signal小区参考信号)资源之外的区域,该有效区域包括:原LTE系统的前3个OFDM符号所对应的时频区域和上述原MPBCH资源映射区域,如图1-2所示,图1-2所示的空白格中映射MPBCH资源。
本公开中,基站可以参照原LTE系统在预设子帧内映射CRS资源,参见图1-2中CRS APs 0/1、CRS APs 2/3的部署。
关于目标物理资源的映射,根据小区内各个MTC设备的设备类型是否一致, 上述步骤12的实施可以包括两种情况:
情况一,上述小区内至少有一个MTC设备不支持从目标资源区域搜索预设MTC系统信息,即小区内至少有一个第一类MTC设备。
此种情况下,基站按照第一映射方式在所述预设子帧的数据区域映射MPBCH资源。所述数据区域的时间区域对应为所述预设子帧中去除所述控制区域外的时间区域,所述数据区域的频率区域对应所述原LTE系统中预设MTC系统信息所占频率资源区域。
参见图4-1根据一示例性实施例示出的一个预设子帧的MPBCH资源映射区域的示意图,一个预设子帧的MPBCH资源映射区域包括:一个预设子帧对应的时频区域中、预设6个PRB对的后11个OFDM符号所对应的时频区域,即原MPBCH资源映射区域。
情况二,上述小区内的MTC设备均支持从目标资源区域搜索预设MTC系统信息,即上述小区内的MTC设备均属于第二类MTC设备。
此种情况下,基站可以默认采用第二映射方式在预设子帧中映射MPBCH资源,或者,基站自主决定采用何种映射方式在预设子帧中映射MPBCH资源。
对于基站自主确定映射方式的情况,参见图5根据一示例性实施例示出的另一种传输MTC系统信息的方法流程图,上述步骤12可以包括:
在步骤1201中,确定所述目标物理资源的目标资源映射方式;
本公开实施例中,若基站确定小区内的MTC设备均属于第二类MTC设备,可以根据配置灵活性等需求,自主确定采用第一映射方式或者第二映射方式在预设子帧中映射MPBCH资源。
在步骤1202中,根据所述目标资源映射方式生成广播配置信息,所述广播配置信息用于告知所述MTC设备所述目标物理资源在所述预设子帧中的映射范围;
本公开实施例中,在基站自主确定目标资源映射方式之后,还可以根据上述目标资源映射方式生成广播配置信息,以告知小区内的MTC设备上述MPBCH资源的映射范围。
在一实施例中,上述广播配置信息可以包括:目标资源映射方式,如第一映射方式。
在本公开另一实施例中,上述广播配置信息也可以包括:MPBCH资源的具体映射范围,比如后11个OFDM符号。
在步骤1203中,通过广播信令将所述广播配置信息下发给所述MTC设备;
本公开中,基站可以通过广播信令将所述广播配置信息广播到所述小区内的各个MTC设备,使得各个MTC设备在获取预设MTC系统信息时,可以准确定位目标搜索区域。
其中,在一实施例中,可以通过设置于主信息块MIB中的1个bit承载上述广播配置信息,比如,当上述1个bit置为0时,表示第一映射方式;反之,当上述1个bit置为1时,表示第二映射方式。
在本公开另一实施例中,在MTC设备接入小区网络后,基站也可以通过SIB(System Information Block,系统信息块)中的1个bit承载上述广播配置信息,广播上述广播配置信息以知晓MTC设备。
本公开实施例中,针对上述情况二,即基站小区内的各个MTC设备均支持从目标资源区域搜索预设MTC系统信息的情况,基站可以根据灵活性需求自主决定采用何种资源映射方式进行MPBCH资源映射;并生成广播配置信息广播给各MTC设备,以使MTC设备在检测预设MTC系统信息时,可以根据上述广播配置信息精确定位目标搜索区域,提高MTC设备对预设MTC系统信息如MIB的检测效率,从而提高所述MTC设备接入基站小区的效率。
在步骤1204中,根据所述目标资源映射方式在所述预设子帧中映射所述目标物理资源。
根据目标资源映射方式的不同,上述步骤1204的实施可以包括:
方式一,按照第一映射方式进行目标物理资源映射,与上述情况一相同,此处不再赘述。
方式二,按照第二映射方式在预设子帧对应的时频区域进行目标物理资源映射。
其中,基站按照第二映射方式在一个预设子帧中映射MPBCH资源时,可用的有效映射区域包括:目标资源区域和原MPBCH资源映射区域,如图4-2所示的预设子帧中6个PRB对所占的时频区域。
本公开中,针对基站按照第二映射方式映射MPBCH资源的情况,基站可以基于不同MTC传输模式以及原MPBCH资源映射区域需要部署的不同类型MPBCH单位资源,确定如何映射目标物理资源。
相关技术中,MTC系统可以采用以下四种MTC传输模式进行信息传输,分别为:机器类通信频分双工常规循环前缀MTC FDD Normal CP模式;机器类通信频分双工增强循环前缀MTC FDD Extended CP模式;机器类通信时分双工常规循环前缀 MTC TDD Normal CP模式;机器类通信时分双工增强循环前缀MTC TDD Extended CP模式。
每一种MTC传输模式下,基站在预设子帧的原MPBCH资源映射区域部署四种PBCH单位资源,分别为:PBCH symbol 1、PBCH symbol 2、PBCH symbol 3、PBCH symbol 4。不同MTC传输模式下,上述四种PBCH单位资源的映射方式也不同,参见图6-1、图7、图8、图9所示。
基于此,参见图10根据一示例性实施例示出的另一种传输MTC系统信息的方法流程图,上述步骤12可以包括:
在步骤121中,根据预设MTC传输模式确定所述目标资源区域的目标映射子模式;
上述目标映射子模式用于表示在上述目标资源区域中如何映射目标物理资源如MPBCH资源。
本公开中,至少可以采用以下两种方式实施步骤121:
第一种实施方式,按照协议规定确定上述目标映射子模式
本公开中,5G NR协议可以针对每一种预设MTC传输模式预置有对应的映射子模式,在基站确定当前小区采用的MTC传输模式后,即可确定对应的目标映射子模式。
在一实施例中,基站可以根据当前小区的MTC传输模式查询预设资源映射列表,确定所述MTC传输模式对应的目标映射子模式。其中,所述预设资源映射列表包括:MTC传输模式与预设映射子模式的对应关系,所述预设映射子模式用于指示在所述目标资源区域如何映射PBCH符号。示例性的,上述预设资源映射列表可以如表一所示:
表一
本公开中,一个目标资源区域包括三个子区域。每一个子区域在时域上等于一个符号所占时长;在频域上等于72个连续子载波所占的频率范围,即6个PRB对所 占的频率范围。对应上述目标资源区域中的三个符号,上述三个子区域可以分别表示为S0、S1、S2。
假设基站确定当前小区的MTC传输模式为MTC FDD Normal CP模式,查询表一可知,对应的目标映射子模式为:在#0子帧的前3个OFDM符号所对应的时频区域即子区域S0、S1、S2内依次映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 3;在#9子帧的子区域S0、S1、S2内,依次映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 4,上述目标映射子模式可以简单表示为:(#0:1、2、3;#9:1、2、4)。
采用此种方式,在MTC设备确定基站采用的MTC传输模式以及第二映射方式的情况下,根据协议规定,可以明确基站在目标资源区域中对MPBCH符号的部署情况,无需基站通过专门信令告知目标映射子模式,节约信令开销。
第二种实施方式,基站可以为预设MTC传输模式动态确定目标映射子模式,即对于同一种MTC传输模式,基站在不同时间内确定的目标映射子模式可能不同。
参见图11根据一示例性实施例示出的另一种传输MTC系统信息的方法流程图,上述步骤121可以包括:
在步骤1211中,根据所述预设MTC传输模式下所述目标资源区域中映射的小区参考信号资源类型确定所述目标映射子模式;
本公开中,针对任意一种MTC传输模式,基站可以根据原LTE系统的相关技术,在预设子帧的目标资源区域内映射CRS资源;并根据上述目标资源区域内映射的CRS资源类型以及原MPBCH资源映射区域内PBCH符号类型与CRS资源类型的关系,确定所述目标资源区域的有效区域中所述目标物理资源的映射模式。上述目标资源区域的有效区域是指上述目标资源区域中去除CRS资源之外的区域。上述CRS资源的类型包括:CRS APs 0/1和CRS APs 2/3。其中,APs表示逻辑上的天线端口Antenna Port,在下行链路中,天线端口与小区参考信号CRS是一一对应的。
在映射目标物理资源之前,根据所述目标资源区域的一个子区域中是否设置有CRS资源,可以将上述三个子区域分为:第一子区域和第二子区域。其中,第一子区域中设置有CRS资源,包括:子区域S0、S1;第二子区域中未设置CRS资源,即子区域S2,如图4-2所示。
本公开中,关于如何确定一个子区域的MPBCH资源映射方式,可以包括:
确定待映射子区域的子区域类型;
若待映射子区域属于上述第一子区域,根据该子区域中映射的CRS资源类型,以及原MPBCH资源映射区域中目标子区域的资源映射情况,确定待映射MPBCH资 源类型,其中,上述目标子区域中部署有相同类型的CRS资源。
如图6-1所示,第9号子帧的子区域S0中映射的CRS资源类型为:CRS APs 0/1;则待映射MPBCH资源的类型可以参见第一个时隙slot的#4符号、第二个slot的#0符号、第二个slot的#4符号所在子区域中映射的MPBCH符号,包括:PBCH symbol 2、PBCH symbol 1。
若当前待映射子区域属于上述第二子区域,即S2,则可以在该子区域内映射任一类型的MPBCH符号。
按照上述规则并对照上述图6-1、图7、图8、图9,上述四种MTC传输模式对应的资源映射子模式可以如表二所示:
表二
基站可以根据上述表二确定任一种映射子模式为目标映射子模式。
示例性的,假设当前小区的MTC传输模式为MTC FDD Normal CP模式,则根据上述表二可知,基站可以采用的映射子模式包括16种,如表三所示:
表三
基站可以确定上述任一种模式为目标映射子模式,如模式二(1、2、3)、(1、2、4)。
在步骤1212中,按照所述目标映射子模式生成模式配置信息;
在基站确定目标子映射模式后,可以根据目标映射子模式的信息生成模式配置信息,以告知MTC设备上述目标映射子模式。
本公开中,上述模式配置信息可以包括具体的MPBCH符号类型,示例性的,假设目标映射子模式为上述模式二,则上述模式配置信息可以包括:(1、2、3)、(1、2、4)。
在本公开另一实施例中,还可以采用预设数量的bit位表示目标映射子模式。如上示例,可以采用4个bit表示MTC FDD Normal CP模式对应的16中映射子模式,例如,当上述4个bit被置为0000时,表示上述表三中的模式一。则上述模式配置信息可以包括:表示目标映射子模式的bit位数值。采用此种位图方式表示目标映射子模式,可以节约信令开销。
在步骤1213中,通过预设广播信令广播所述模式配置信息,以使所述MTC设备根据所述模式配置信息确定所述目标资源区域中所述目标物理资源的映射方式。
同上,基站可以通过广播信令承载上述模式配置信息,广播至MTC设备。
本公开中,基站可以根据灵活性需要,在不同时间可以动态确定预设子帧中目标资源区域内MPBCH资源的映射方式,并在MTC设备搜索MTC系统信息之前,将上述模式配置信息广播给MTC设备,从而确保MTC设备可以从预设子帧中准确解调出预设MTC系统信息如MIB信息。
在步骤122中,按照所述目标映射子模式在所述目标资源区域映射所述目标物理资源;
示例性的,仍以MTC传输模式是MTC FDD Normal CP模式为例,若步骤121确定的目标映射子模式为上述表三中的模式一,则基站在第0号和9号子帧对应的目标资源区域中,分别在子区域S0、S1、S2映射PBCH symbol 1、PBCH symbol 2、PBCH symbol 3,参见图6-2示出了基站按照第二映射方式映射目标物理资源的示意图。
同理,图6-3示出了目标映射子模式为上述模式二时,目标资源区域内的MPBCH资源映射的示意图。如图所示,在第0号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 3,在第9号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 4。
图6-4示出了目标映射子模式为上述模式三时,目标资源区域内的MPBCH资源映射的示意图。如图所示,在第0号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 4,在第9号子帧的子区域S0、S1、S2中, 分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 3。
图6-5示出了目标映射子模式为上述模式四时,目标资源区域内的MPBCH资源映射的示意图。如图所示,在第0号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 4,在第9号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 4。
本公开中,在为第二子区域即子区域S2映射目标物理资源时,若上述目标映射子模式指示的待映射资源类型在原MPBCH资源映射区域中匹配设置有预设CRS资源,则基站按照上述目标映射子模式在对第二子区域进行资源映射时,除了映射上述待映射MPBCH符号外,还需要同时映射相同类型的CRS资源。
仍以MTC传输模式是MTC FDD Normal CP模式为例,若步骤121确定的目标映射子模式为上述表三中的模式十六,可知,第0号子帧和第9号子帧的子区域S2的待映射资源类型分别为:PBCH symbol 2、PBCH symbol 1。二者在原MPBCH资源映射区域中均设置有相应的CRS资源,参见图6-1所示。比如,第0号子帧的原MPBCH资源映射区域中,PBCH symbol 2与CRS APs 0/1或CRS APs 2/3绑定映射。第9号子帧的原MPBCH资源映射区域中,PBCH symbol 1与CRS APs 0/1绑定映射;则基站按照上述模式十六在目标资源区域的子区域S2中进行资源映射时,需要部署相同类型的CRS资源。
示例性的,参见图6-6示出的目标映射子模式为上述模式十六时,目标资源区域内的MPBCH资源映射的示意图。如图所示,在第0号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 2,同时在子区域S2中还映射有CRS APs 0/1;同理,在第9号子帧的子区域S0、S1、S2中,分别映射:PBCH symbol 1、PBCH symbol 2、PBCH symbol 1,同时在子区域S2中还映射有CRS APs 0/1。
此处需要说明的是,在本公开另一实施例中,上述第0号子帧的子区域S2中还可以映射与PBCH symbol 2匹配的CRS APs 2/3。
同理,其它MTC传输模式下目标区域的资源映射方式与上述MTC FDD Normal CP模式类似,相互参见即可,此处不再赘述。
在步骤123中,按照原LTE系统的目标物理资源映射方式在所述预设子帧的数据区域映射所述目标物理资源。
本公开中基站对原MPBCH资源映射区域中的资源部署可以与原LTE系统相同。需要说明的是,该步骤123与步骤122无先后顺序之分,二者也可以同时进行。 示例性的,对应上述图6-2,MTC FDD Normal CP模式下第0号和第9号子帧的资源映射情况,参见图6-7所示。
在步骤13中,通过所述目标物理资源广播所述预设MTC系统信息。
在基站映射目标物理资源之后,可以MTC系统信息如MIB信息载入上述目标物理资源中,广播至小区内的MTC设备,使得MTC设备从预设子帧中获取预设MTC系统信息,并依据上述预设MTC系统信息接入小区网络。
综上,采用本公开提供的传输MTC系统信息的方法,在系统为MTC设备独立部署物理广播信道资源的应用场景中,若MTC设备支持从预设子帧的目标资源区域即原LTE系统预设子帧的控制区域中检测预设MTC系统信息如MIB,基站在进行物理广播资源映射时,可以在上述预设子帧的目标资源区域内映射用于承载预设MTC系统信息的目标物理资源即PBCH资源,增强PBCH资源的映射范围,提高系统资源利用率,进而提高MTC系统信息的传输效率。
相应的,本公开还提供了一种传输MTC系统信息的方法,应用于上述第二MTC设备即支持从目标资源区域搜索预设MTC系统信息的MTC设备中。上述目标资源区域的时间区域为原LTE系统中预设子的控制区域的时间区域,是一个预设子帧的前3个OFDM符号所对应的时间区域,如图1-1所示;频率区域为原LTE系统中预设MTC系统信息如MIB信息所占的频率资源区域。
参见图12根据一示例性实施例示出的一种传输MTC系统信息的方法流程图,所述方法可以包括:
在步骤21中,从所述预设子帧的数据区域中获取用于接入小区网络的预设MTC系统信息,并接入所述小区网络,其中,所述数据区域的时间区域为所述预设子帧中去除所述控制区域外的时间区域,所述数据区域的频率区域对应所述原LTE系统中预设MTC系统信息所占频率资源区域;
本公开中,一个MTC设备在初始接入小区网络时,仍然按照相关技术,获取预设MTC系统信息如MIB信息,并接入小区的MTC网络系统。
在步骤22中,获取基站下发的广播配置信息,所述广播配置信息用于告知所述MTC设备目标物理资源在所述预设子帧中的映射范围,所述目标物理资源用于承载所述预设MTC系统信息;
在MTC设备已接入小区网络、需要再次获取预设MTC系统信息的应用场景中,例如,MTC设备需要系统更新时,或者,MTC设备由空闲态到激活态时,可以接收基站广播的广播配置信息,以确定目标物理资源如MPBCH资源的映射范围,参见上 述步骤1202、步骤1203的描述。
在步骤23中,根据所述广播配置信息在所述预设子帧中检测预设MTC系统信息。
与上述步骤1202、步骤1203相对应,上述步骤23的实施包括两种情况:
情况一,若上述广播配置信息指示目标物理资源的映射方式为上述第一映射方式,则MTC设备仍按照相关技术在预设子帧对应的原MPBCH资源映射区域内检测预设MTC系统信息,如图4-1所示。
情况二,若上述广播配置信息指示目标物理资源的映射方式为上述第二映射方式,则上述步骤23具体为:MTC设备在预设子帧的有效映射区域内检测预设MTC系统信息,如图4-2所示。
针对上述情况二,MTC设备可以采用以下任一方式在预设子帧的有效映射区域内检测预设MTC系统信息:
参见图13根据一示例性实施例示出的一种传输MTC系统信息的方法流程图,上述步骤23可以包括:
在步骤231中,若所述广播配置信息指示所述目标物理资源的映射方式为第二映射方式,根据当前小区的MTC传输模式确定所述目标资源区域的目标映射子模式;
即若广播配置信息指示基站按照上述第二映射方式在所述目标资源区域内映射目标物理资源,MTC设备需要首先确定目标资源区域内各子区域的资源映射方式,即目标映射子模式。
本公开中,MTC设备可以按照下述任一方式确定目标映射子模式:
方式一,MTC设备按照系统协议规定的资源映射模式检测MTC系统信息,对应上述步骤121的第一种实施方式。
即上述步骤231具体为:根据当前小区的MTC传输模式查询预设资源映射列表,确定所述MTC传输模式对应的目标映射子模式,所述预设资源映射列表包括:MTC传输模式与预设映射子模式的对应关系,所述预设映射子模式用于指示所述基站在所述目标资源区域如何映射物理广播信道PBCH符号;
其中,上述预设资源映射列表如上述表一所示。
本公开中,MTC设备在确定基站采用的MTC传输模式后,可以根据上述预设资源映射列表,明确基站在目标资源区域中对MPBCH符号部署时所采用的目标映射子模式。
方式二,与上述步骤121的第二种实施方式相对应,MTC设备根据基站下发 的模式配置信息确定目标映射子模式。
参见图14根据一示例性实施例示出的一种传输MTC系统信息的方法流程图,上述步骤231可以包括:
在步骤2311中,接收所述基站广播的模式配置信息;
在步骤2312中,根据所述模式配置信息,确定所述目标资源区域的所述目标映射子模式。
本公开实施例中,MTC设备可以根据基站广播到的模式配置信息,确定基站在预设子帧的目标资源区域,采用何种映射方式部署MPBCH符号,以便后续MTC设备可以准确解析预设MTC系统信息。
在步骤232中,根据所述目标映射子模式在所述预设子帧的有效映射区域中检测所述预设MTC系统信息。
MTC设备在确定目标映射子模式之后,在上述有效映射区域的目标资源区域中,按照上述目标映射子模式解调部分预设MTC系统信息;并在上述有效映射区域的原MPBCH资源映射区域中,按照相关技术间解调另一部分预设MTC系统信息,从而快速解析预设MTC系统信息。
参见图15据一示例性实施例示出的一种传输MTC系统信息的方法流程图,在步骤22之前,所述方法还可以包括:
在步骤20中,向所述基站上报设备能力信息,所述设备能力信息用于指示所述MTC设备是否具备从所述目标资源区域搜索预设MTC系统信息的能力,以使所述基站确定所述MTC设备的所述信息检测能力。
本公开实施例中,MTC设备接入小区网络之后,还可以向基站上报自身的能力信息,以便基站确定该MTC设备的信息检测能力,与上述图3所示实施例相对应,此处不再赘述。
MTC设备解调MPBCH资源承载的预设MTC系统信息时,需要对PBCH的各个符号在长时间内进行功率累加,尝试解调。因此在固定时间内,MPBCH资源部署及传输的越多,MTC设备就能累积更多的PBCH接收功率,成功解调预设MTC系统信息的概率也会更大。因此,采用本公开提供的传输MTC系统信息的方法,当基站采用第二映射方式在预设子帧中映射目标物理资源时,可以有效利用系统资源,提高预设MTC系统信息的解调效率。
对于前述的各方法实施例,为了简单描述,故将其都表述为一系列的动作组合,但是本领域技术人员应该知悉,本公开并不受所描述的动作顺序的限制,因为依据本 公开,某些步骤可以采用其他顺序或者同时进行。
其次,本领域技术人员也应该知悉,说明书中所描述的实施例均属于可选实施例,所涉及的动作和模块并不一定是本公开所必须的。
