小区公共信号的覆盖增强、获取方法、装置、基站及终端
相关申请的交叉引用
本申请主张在2017年1月24日在中国提交的中国专利申请号No.201710055182.6的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信应用的技术领域，特别是指一种小区公共信号的覆盖增强、获取方法、装置、基站及终端。
背景技术
MF(Multe Fire)是一种将长期演进(Long Term Evolution，LTE)技术扩展到非授权频段的无线接入技术，该技术可以不借助授权频段载波独立运行于非授权频谱中。为了与其他在非授权频段设备(如WiFi设备)公平占用非授权频段信道及避免非授权频段设备之间相互干扰，MF物理层引入类似WiFi的载波监听技术的先听后说(Listen Before Talk，LBT)机制。在基站或终端监听到非授权频段信道被占用时，即LBT失败时，停止发送信号，当监听到信道空闲时，即LBT成功时才发送信号。
为了提高LBT机制下基站的下行公共控制信号传输效率，MF引入了发现参考信号(Discovery Reference Signal，DRS)，DRS包含了主要的下行公共控制信号，包括MF主同步信号(Multefire Primary Sync Signal，MF-PSS)、MF辅同步信号(Multefire Secondary Sync Signal，MF-SSS)、小区参考信号(Cell Reference Signal，CRS)、MF主系统信息块(Master Information Block Multefire，MIB-MF)和MF系统信息块(System Information Block Multefire，SIB-MF)，DRS占用一个下行子帧中的12个或14个符号(Symbol)。其中，MIB-MF是通过MF广播信道MF-PBCH进行发送，SIB-MF是通过物理下行共享信道(Physical Downlink Shared Channel，PDSCH)进行发送，这里，该下行共享信道是由物理下行控制信道(Physical Downlink Control Channel，PDCCH)中的公共搜索空间(CSS)进行调度。用户设备(User Equipment， UE)可以在发现信号测量时间配置(Discovery Signals Measurement Timing Configuration，DMTC)窗口内接收DRS以进行下行同步、接收MIB-MF和SIB-MF。MF小区只在DRS子帧或者其他有PDSCH发送的子帧发送CRS。
考虑到某些设备应用到一些特殊的地理位置，且该地理位置的信道衰落比较大，需要进行覆盖增强。例如，停车库里面的监控摄像头，装在地下室里的水表和电表等装置，由于穿透损失比较大，需要对信号质量进行扩大，或者对传输距离进行增强，即覆盖增强(CE，coverage enhancement)。因此，就需要对DRS进行覆盖增强，使得处于深度衰落的用户或者装置可以搜索并接入MulteFire小区。目前，针对这一问题，并未有具体的措施来解决DRS的覆盖增强问题。

具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合具体实施例及附图进行详细描述。
本公开的实施例提供了一种小区公共信号的覆盖增强、获取方法、基站及终端，解决了相关技术中没有具体的措施来提升小区公共信号覆盖的问题。
第一实施例
如图1所示，本公开的实施例提供了一种小区公共信号的覆盖增强方法，应用于基站，包括：
步骤101：根据小区预设的覆盖增强的程度，确定进行覆盖增强的增强小区公共信号的频域资源及时域资源。
这里的小区公共信号包含MF主系统信息块。可具体为MF网络中的发现参考信号DRS，如MIB-MF、MF-PSS和MF-SSS。为区别于基本覆盖下的MIB-MF，以及长期演进(Long Term Evolution，LTE)/LTE-A系统中的MIB (定义为MIB-LTE)，将进行覆盖增强的MIB-MF定义为增强的MIB-MF(enhanced MIB-MF，eMIB-MF)，其中，eMIB-MF所携带的控制信息，可能与MIB-MF不同。对应的，将承载eMIB-MF的传输信道定义为eMF-PBCH(enhanced MF-PBCH，增强的MF-PBCH)。eMIB-MF可以是对MIB-MF的内容进行扩展，用于需要覆盖增强的用户或者装置，在新版本系统中，MF-PBCH和eMF-PBCH所承载的信息是一样的，都是承载扩展后的MIB-MF。新用户可以对MF-PBCH和eMF-PBCH进行合并解码，旧版本用户仍解码MF-PBCH。eMIB-MF也可以是完全不同于MIB-MF的信息，由一个新的eMF-PBCH承载，在新版本系统中，新用户只能解码eMF-PBCH来获得系统信息。
同理，进行覆盖增强后的MF-PSS和MF-SSS定义为增强的MF-PSS(enhanced MF-PSS，eMF-PSS)和增强的MF-SSS(enhanced MF-SSS，eMF-SSS)。eMF-PSS是和MF-PSS相同的序列，是将MF-PSS拓展到了不同的时频资源进行发送，以实现覆盖增强。因此，eMF-PSS包含MF-PSS，MF-PSS也可以被覆盖增强的用户或者装置进行解码。对应的，相同设计也适用于eMF-SSS。eMF-PSS也可以是和MF-PSS不同的序列，携带有其他额外的信息。那么，覆盖增强的用户或者装置无法解码MF-PSS。对应的，相同设计也适用于eMF-SSS。
在本公开的具体实施例中，定义系统的基本传输时间间隔为TTI(Transmission Time Interval)。从绝对值看，TTI在不同频段可以有不同的取值。例如，在6GHz以下，TTI＝1ms；在6-30GHz，TTI＝0.5ms；在30GHz以上，TTI＝0.25ms。从逻辑上看，TTI可以包含一定数目的符号，如1个TTI包含14个OFDM符号，或者12个OFDM符号。或者，1个TTI包含6个或7个OFDM符号。
此外，定义eMF-PBCH的基本传输带宽为
Figure PCTCN2018073166-appb-000001
eMF-PSS的基本传输带宽为
Figure PCTCN2018073166-appb-000002
和eMF-SSS的基本传输带宽为
Figure PCTCN2018073166-appb-000003
这里，在一个基本传输带宽内，各个信道是可以独立解码的。具体的，
Figure PCTCN2018073166-appb-000004
和
Figure PCTCN2018073166-appb-000005
表示为频域上资源块(Resource block，RB)的个数，是一个逻辑值，每个RB包含一定数目的子载波。在不同频段或者不同应用下，该逻辑值的取值可 能有所变化。由于在不同场景，例如不同频段，或者不同应用下，子载波间隔的取值有所不同，因此，eMF-PBCH，eMF-PSS和eMF-SSS的绝对带宽会随着场景有所变化。相较于MF-PBCH，
Figure PCTCN2018073166-appb-000006
可以比6个PRB大，或者等于6个PRB。
传输eMF-PBCH时，eMF-PBCH的基本传输带宽内的逻辑资源可以集中式地映射到频域上，即，eMF-PBCH的物理资源在频域上是连续的。在另一个例子中，eMF-PBCH基本传输带宽内的逻辑资源是分布式地映射到频域上，即，eMF-PBCH的物理资源在频域上是离散的。在一个例子中，eMF-PBCH的逻辑资源以一定的间隔
Figure PCTCN2018073166-appb-000007
分布式地映射到物理资源上，这里的间隔是基于PRB大小的一个数值。
具体的，定义eMF-PBCH的基本映射单元
Figure PCTCN2018073166-appb-000008
那么，eMF-PBCH一个基本传输带宽内的资源以
Figure PCTCN2018073166-appb-000009
为单位，映射到
Figure PCTCN2018073166-appb-000010
个不同的频域位置上，每两个基本映射单元之间的距离即
Figure PCTCN2018073166-appb-000011
这里，
Figure PCTCN2018073166-appb-000012
是预先定义的，例如3。
Figure PCTCN2018073166-appb-000013
的取值基于系统带宽，例如
Figure PCTCN2018073166-appb-000014
或者，还可以基于小区ID，例如，
Figure PCTCN2018073166-appb-000015
进一步，eMF-PBCH的一个基本传输带宽可位于系统带宽的一个特定位置，该位置是固定的，或者基于一个函数得到，其中该函数的参数包含小区ID，系统帧号。在这种情况下，定义eMF-PBCH传输的中心频点和通信系统的中心频点的偏差为
Figure PCTCN2018073166-appb-000016
上述偏差也可以定义eMF-PBCH基本传输带宽的上边界和通信系统中心频点的距离。或者可以定义eMF-PBCH基本传输带宽的下边界和系统中心频点的距离。这里的，通信系统可具体指时分同步码分多址TD-SCDMA、全球微波互联接入WiMAX、LTE/LTE-A、LAA、MulteFire以及后续可能出现的第五代、第六代、第N代移动通信系统。

基于上述的资源映射方式，以及不同的频偏，可以实现eMF-PBCH在不同的频域位置上进行传输。上述

和
Figure PCTCN2018073166-appb-000034
所包含的符号数有所变化，其取值并不是固定的。此外，一个符号的持续时间有所不同，因此，eMF-PBCH和eMF-PSS/eMF-SSS的基本传输时间的绝对值也会变化。相较于LTE/LTE-A系统的4个符号PBCH，以及MF1.0系统中的6个符号MF-PBCH，eMF-PBCH可能占用{1，2，4，5，6}个符号。
在本公开的具体实施例中，MF系统中可存在eMIB-MF的增强，没有eMF-PSS和eMF-SSS的覆盖增强。也可对MF-MIB和MF-PSS/SSS都进行了覆盖增强。在不同情况下，eMF-PBCH的基本传输时间大小会有所不同，资源映射也有所不同，为实现覆盖增强，会有多组时频资源用于传输eMF-PBCH。
在上述时频资源实现覆盖增强可具体为在eMF-PBCH占据多组时频资源上进行重复性传输，每组的大小是eMF-PBCH的基本传输带宽以及基本传输时间，该基本传输带宽为eMF-PBCH在频域上所占用的资源块的个数。上述每组资源在时域上的大小具体为eMF-PBCH的基本传输时间。
该步骤通过确定增强小区公共信号的频域资源及时域资源，以便于后续在所确定的频域资源和/或时域资源重复传输所述增强小区公共信号，以实现小区公共信号的覆盖增强。具体的，上述步骤101中，在基站所覆盖的小区支持覆盖增强时，可根据该小区实际覆盖增强的程度(如支持3倍覆盖增强)， 确定频域资源和时域资源，以便于节省时频资源。在这种实例下，只有覆盖增强程度不大于小区实际能力的用户可以检测到该小区。
另一个实例中，上述步骤101可具体包括：根据所述小区预先定义的最大的覆盖增强程度，确定进行覆盖增强的增强小区公共信号的频域资源及时域资源。
具体的，如基站支持覆盖增强，基站不根据本小区的实际覆盖增强程度(如当前只支持3倍覆盖)，按照预先定义的最大覆盖增强程度(如6倍覆盖增强)，以便于所有不同覆盖增强要求的用户都可以检测到小区，并了解小区的实际覆盖增强能力。
步骤102：在所确定的频域资源和/或时域资源上，重复传输所述增强小区公共信号。
具体的，若所述频域资源为所述基本传输带宽，则在时域资源上，重复传输所述增强小区公共信号；若所述频域资源包含多组资源，且每组资源的频宽为所述基本传输带宽，则在频域资源上重复传输所述增强小区公共信号，或在所述频域资源和所述时域资源上重复传输所述增强小区公共信号，以实现增强小区公共信号的覆盖增强。
本公开实施例的小区公共信号的覆盖增强方法，根据小区预设的覆盖增强的程度，确定进行覆盖增强的增强小区公共信号的频域资源及时域资源；在所确定的频域资源和/或时域资源上，重复传输所述增强小区公共信号。本公开实施例通过在频域资源和/或时域资源上重复传输增强小区公共信号，实现了小区公共信号的覆盖增强，使得处于深度衰落的用户或者装置也可以搜索并接入当前小区。
第二实施例
如图2所示，本公开的实施例还提供了一种小区公共信号的覆盖增强方法，应用于基站，包括：
步骤201：根据小区预设的覆盖增强的程度，对所述增强小区公共信号对应的增强符号进行资源映射处理，得到所述增强小区公共信号的时域资源。
具体的，将每个传输时间间隔TTI中的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号。
在本公开的具体实施例中，假定上述小区公共信号为eMF-PBCH，则对于一次基本的完整性传输，
Figure PCTCN2018073166-appb-000035
的可能取值为{1，2，4，5，6}。如图3所示，eMF-PBCH的一次基本传输需要6个符号，即
Figure PCTCN2018073166-appb-000036
其中，eMF-PBCH的第一个增强符号1，第二个增强符号2，第五个增强符号5和第六个增强符号6上有小区参考信号CRS，第三个增强符号3和第四个增强符号4上没有CRS。
在图4中，eMF-PBCH的一次基本传输需要5个符号，即
Figure PCTCN2018073166-appb-000037
其中，eMF-PBCH的第一个增强符号1，第二个增强符号2和第五个增强符号5上有小区参考信号CRS，第三个增强符号3和第四个增强符号4上没有CRS。
在图5A中，eMF-PBCH的一次基本传输需要4个符号，即
Figure PCTCN2018073166-appb-000038
其中，在一个例子中，eMF-PBCH的第一个增强符号1和第二个增强符号2上有小区参考信号CRS，第三个增强符号3和第四个增强符号4上没有CRS。在图5B中，eMF-PBCH的第一个增强符号1，第二个增强符号2和第四个增强符号4上有小区参考信号CRS，增强符号3上没有CRS。
eMF-PBCH的增强符号是一一映射到一个TTI中的相应数目的符号，例如，OFDM符号。在上述中，如果eMF-PBCH符号有CRS，表示该符号必须映射到有CRS的OFDM符号上，或者映射到没有CRS的OFDM符号上。当映射到没有CRS的OFDM符号上时，必须有部分资源粒子用于发送CRS，或者部分资源粒子不发送任何信号，即图6A、图6B、图7、图8、图9、图10、图11及图12中的Copied CRS or empty(复制的CRS或空白资源)。如果某个eMF-PBCH符号上没有CRS，在做资源映射时，则不能映射到有CRS的OFDM符号上。
具体的，上述步骤201包括将每个传输时间间隔TTI中的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号。
另外，在本公开的具体实施例中，eMF-PBCH的基本传输带宽是和基本传输时间是成比例的，以维持特定的编码效率。假定eMIB-MF的信令开销是40bits，每次独立解码的编码效率和MIB-MF(独立编码效率为40/(2688/4) ＝0.06)相当，则有eMF-PBCH的基本传输带宽为
Figure PCTCN2018073166-appb-000039
分别对应
Figure PCTCN2018073166-appb-000040
为{1，2，4，5，6}。假定，eMIB-MF的信令开销是40bits，每次独立解码的编码效率和MIB-LTE(独立编码效率为40/(1920/4)＝0.08)相当，相应的，可以得到eMF-PBCH的基本传输带宽为

注意一点，若一个TTI中含有的OFDM符号，不是eMF-PBCH基本传输时间的整数倍，则eMF-PBCH的部分符号不能被传输，网络基于删截(puncture)，只传输eMF-PBCH的部分符号这里，puncture定义为eNB按照固定码率对eMF-MIB进行编码，资源映射过程中遇到不可用资源时，需要打掉相应的eMF-PBCH调制符号，不进行发送。
下面结合附图说明本公开实施例中资源映射的具体实现方案。
实现方式一
如图6A、图6B及图7所示，增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应5个增强符号，且5个增强符号中的第一个增强符号、第二个增强符号及第五个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含12个符号(TTI正常长度是14个符号，最后两个符号不可用)，且所述TTI内存在主同步信号PSS、辅同步信号SSS、MF-PSS、MF-SSS及MF-PBCH，则在每个所述TTI中的第三个符号及第八个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第四个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第六个符号及第十个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第七个符号及第十一个符号中映射所述eMF-PBCH的第四个增强 符号，在每个所述TTI中的第五个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号。
上述实现方式也适用于TTI包含14个符号，且14个符号均可用。这时，最后两个符号可以不发送信号，或者只发送eMF-PBCH的其中两个符号。
上述实现方式一适用于不存在eMF-PSS/SSS或存在eMF-PSS/SSS且eMF-PSS/SSS与eMF-PBCH正交的情况。一个TTI的正常长度是14个符号，但在某些情况下，一个TTI只包含12个符号，即该TTI是个非正常TTI。当该TTI中存在PSS/SSS,MF-PSS/SSS，MF-PBCH(位于中心6个PRB)，或存在PSS/SSS(位于中心6个PRB)，或不存在PSS/SSS，MF-PSS/SSS，MF-PBCH，MF-SIB时，eMF-PBCH的一个资源映射示例如图6A所示。在图6A中，eMF-PBCH位于和中心频点相隔
Figure PCTCN2018073166-appb-000055
的频域资源上，时域上的基本传输时间为5个符号，频域上的基本传输带宽是6个PRB。图6A中，eMF-PBCH的传输只位于系统中心频点的一侧。R0和R1分别表示eMF-PBCH的重复传输0和重复传输1，这里，eMF-PBCH在一个TTI内可以重复两次。
需要说明的是，图6A所示的映射方案适用于TTI内存在PSS/SSS,MF-PSS/SSS,MF-PBCH的情况，且控制区域(物理下行控制信道PDCCH)的长度不大于2个符号。
基于类似的设计，图6B给出了TTI正常长度为12个符号(拓展CP)时eMF-PBCH的资源映射方式。在每个所述TTI中的第三个符号及第七个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第四个符号及第八个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第五个符号及第九个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第六个符号及第十一个符号中映射所述eMF-PBCH的第四个增强符号，在每个所述TTI中的第十个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号。
上述实现方式一的另一资源映射方案，如图7所示，这里，TTI内存在PSS/SSS，MF-PSS/SSS和MF-PBCH。在图7中，eMF-PBCH位于和系统中心频点相隔
Figure PCTCN2018073166-appb-000056
的频域资源上，时域上的基本传输时间为5个符号，频 域上的基本传输带宽是6个PRB。基本传输带宽的资源，一分为二，以间隔
Figure PCTCN2018073166-appb-000057
映射到频域上。即在图7中，eMF-PBCH的传输位于系统中心频点的两边。R0和R1分别表示eMF-PBCH的重复传输0和重复传输1，这里，eMF-PBCH在一个TTI内可以重复传输两次。
需要说明的是，图7所示的资源映射方案中，由于存在MF-PSS/SSS等信号的传输，控制区域的长度不能大于2个符号。
实现方式二
如图8所示，所述增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应5个增强符号，且5个增强符号中的第一个增强符号、第二个增强符号及第五个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含14个符号，且所述TTI内存在PSS和SSS(PSS/SSS在#5和#6上进行传输)，不存在MF-PSS、MF-SSS及MF-PBCH，则在每个所述TTI中的第三个符号及第八个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第四个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第十个符号及第十三个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第十一个符号及第十四个符号中映射所述eMF-PBCH的第四个增强符号，在每个所述TTI中的第五个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号。
上述实现方式二所对应的资源映射方案适用于不存在eMF-PSS/SSS或存在eMF-PSS/SSS且eMF-PSS/SSS的频域资源与eMF-PBCH的频域资源正交的情况。eMF-PBCH可以包含中心或非中心6个PRB、或包含中心或非中心6个PRB的一部分，或不包含中心或非中心6个PRB。这里，控制区域长度不大于2。
另外，上述实现方式一及上述实现方式二中，控制区域的时间长度不能大于2个符号，当控制区域的时间长度大于2个符号时，eNB需要对eMF-PBCH进行删截puncture。进行puncture时，用户总是默认eNB跳过了 用于公共控制信息的资源，例如，物理控制格式指示信道PCFICH，公共PDCCH(cPDCCH)，以及调度SI的公共控制信息。跳过cPDCCH以及调度SI的公共控制信息时，eNB可只跳过聚合级别为4所对应的时频资源，也可只跳过聚合级别为8所对应的时频资源，在eNB也可跳过聚合级别4和8所对应的所有时频资源。
此时，上述步骤201可具体包括：对所述增强符号进行删截puncture处理，并对puncture处理后的增强符号进行资源映射处理，得到所述增强小区公共信号的时域资源。
此外，如果eMF-PBCH和部分CSI-RS相撞，eNB应puncture eMF-PBCH。其中，eMF-PBCH所占用的频谱资源不能用于其他数据的传输。
实现方式三
如图9所示，所述增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应6个增强符号，且6个增强符号中的第一个增强符号、第二个增强符号、第五个增强符号及第六个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含12个符号，且所述TTI内存在PSS、SSS、MF-PSS、MF-SSS及MF-PBCH，则在每个所述TTI中的第一个符号及第八个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第二个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第三个符号及第十个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第四个符号及第十一个符号中映射所述eMF-PBCH的第四个增强符号，在每个所述TTI中的第七个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号，在每个所述TTI中的第五个符号及第七个符号中映射所述eMF-PBCH的第六个增强符号。
上述实现方式三中，eMF-PBCH位于和中心频点相隔
Figure PCTCN2018073166-appb-000058
的频域资源上，时域上的基本传输时间为6个符号，频域上的基本传输带宽是6 个PRB。R0和R1分别表示eMF-PBCH的重复传输0和重复传输1。在R1重复传输时，eMF-PBCH符号1和符号2映射到控制区域，这里，认为控制区域的长度总是设为2。由于控制区域有公共控制信号，例如PCFICH，cPDCCH，以及调度公共广播数据的公共调度信令，认为eNB总是puncture eMF-PBCH，以免影响原有用户或新用户解码公共控制信号。因此，eMF-PBCH在一个TTI内的重复次数可以不为整数。
上述实现方式三中，eMF-PBCH位于系统中心的两侧，当然，eMF-PBCH可以只位于系统中心的一侧，可参考图7。此外，该实现方式三适用于当前TTI存在PSS/SSS，MF-PSS/SSS，MF-PBCH(位于中心6个PRB)，或不存在PSS/SSS，MF-PSS/SSS，MF-PBCH(位于中心6个PRB)，或只存在PSS/SSS(中心6个PRB)。该实现方式三适用于系统中存在eMF-PSS/SSS的情况，且eMF-PSS/SSS和eMF-PBCH的频谱资源是正交的。
实现方式四
如图10所示，所述增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应6个增强符号，且6个增强符号中的第一个增强符号、第二个增强符号、第五个增强符号及第六个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含14个符号，且所述TTI内不存在PSS、SSS、MF-PSS、MF-SSS及MF-PBCH，则在每个所述TTI中的第三个符号及第八个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第四个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第六个符号及第十个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第七个符号及第十一个符号中映射所述eMF-PBCH的第四个增强符号，在每个所述TTI中的第五个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号，在每个所述TTI中的第十三个符号及第十四个符号中映射所述eMF-PBCH的第六个增强符号。
当系统中心6PRB不传输MF-PSS/SSS，MF-PBCH，以及PSS/SSS时，eMF-PBCH可以占用系统中心的6个PRB，或者6个PRB的一部分，且eNB不能调度其他数据在eMF-PBCH所占资源中进行传输。eMF-PBCH可以在系统中心频点的一侧或者两侧。
另外，若在某些特定时刻，例如MF系统的DRS子帧，一个TTI长度从14变为12个符号，此时，eNB就不发送eMF-PBCH的最后两个符号，即进行puncture处理。上述实现方式四适用于不存在eMF-PSS/SSS或存在eMF-PSS/SSS且eMF-PSS/SSS与eMF-PBCH正交的情况。
实现方式五
如图11所示，所述增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应5个增强符号，且5个增强符号中的第一个增强符号、第二个增强符号及第五个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含14个符号，且所述TTI内的第六个符号和第七个符号存在增强的MF-SSS、第七个符号存在增强的MF-PSS，则在每个所述TTI中的第三个符号及第八个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第四个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第十个符号及第十三个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第十一个符号及第十四个符号中映射所述eMF-PBCH的第四个增强符号，在每个所述TTI中的第五个符号及第十二个符号中映射所述eMF-PBCH的第五个增强符号。
上述实现方式五中，适用于TTI中有eMF-PSS/SSS的情况。
实现方式六
如图12所示，所述增强小区公共信号为增强的MF物理广播信道eMF-PBCH，且所述eMF-PBCH对应4个增强符号，且4个符号中的第一个增强符号、第二个增强符号及第四个增强符号中包含CRS；及
将每个传输时间间隔TTI中包含小区参考信号CRS的符号或不包含CRS 的符号，映射包含CRS的增强符号，并将所述TTI中不包含CRS的符号，映射不包含CRS的增强符号的步骤，包括：
若每个所述TTI包含12个符号，且所述TTI内的第六个符号和第七个符号存在增强的MF-SSS、第七个符号存在增强的MF-PSS，则在每个所述TTI中的第八个符号及第十二个符号中映射所述eMF-PBCH的第一个增强符号，在每个所述TTI中的第五个符号及第九个符号中映射所述eMF-PBCH的第二个增强符号，在每个所述TTI中的第三个符号及第十个符号中映射所述eMF-PBCH的第三个增强符号，在每个所述TTI中的第四个符号及第十一个符号中映射所述eMF-PBCH的第四个增强符号。
上述实现方式六中，适用于TTI中有eMF-PSS/SSS的情况。
步骤202：根据所述增强小区公共信号的基本传输带宽，确定所述增强小区公共信号的频域资源，所述基本传输带宽为所述增强小区公共信号在频域上所占用的资源块的个数。
具体的，在频域上选取多组资源作为所述增强小区公共信号的频域资源，其中，每组资源的频宽等于所述基本传输带宽，且多组资源在频域上为离散的或连续的。此时，在一个TTI内，覆盖增强的用户可以检测到系统信息或者实现同步，eMIB-MF的覆盖增强通过频域上的重复传输。
进一步地，根据所述增强小区公共信号传输的中心频点与通信系统中心频点的偏差，确定第一组资源的中心频点，并根据所述第一组资源的中心频点及预设跳频间隔，得到所述多组资源中除所述第一组资源之外的其他组资源的频域位置。
如图13所示，每个资源块block代表eMIB-MF在一个基本传输带宽内的信号传输，且每个block可以支持eMIB-MF的1-2次重复性传输。多组资源在频域上可以是离散的，也可以是连续的。每组资源的频域位置，可以基于重复索引和第一组起始资源得到。
例如，在该示例中，第一个资源块的中心频点是基于偏差
Figure PCTCN2018073166-appb-000059
得到的，其他组的频域资源则是在此基础上增加一个跳频间隔
Figure PCTCN2018073166-appb-000060
得到。这里，跳频间隔是固定的，其他组的频域资源位置都是基于第一组的频域资源以及当前组的重复索引n得到。其中，上述偏差
Figure PCTCN2018073166-appb-000061
为预设数值或为根据物理小 区标识ID得到的。频域资源分布于通信系统中心频点的一侧或两侧。
步骤203：若所述频域资源为所述基本传输带宽，则在时域资源上，重复传输所述增强小区公共信号。
在时域资源上重复传输增强小区公共信号可具体包括在每个TTI内重复传输增强小区公共信号或在后续TTI内重复传输增强小区公共信号，以实现小区公共信号的覆盖增强。
步骤204：若所述频域资源包含多组资源，且每组资源的频宽为所述基本传输带宽，则在频域资源上重复传输所述增强小区公共信号，或在所述频域资源和所述时域资源上重复传输所述增强小区公共信号。
具体的，如图13所示，在频域资源包含多组资源时，通过频域资源上重复传输所述增强小区公共信号，或如图14所示，在时域资源包含多组资源且时域资源包含多组资源时，在所述频域资源和所述时域资源上重复传输所述增强小区公共信号，实现小区公共信号的覆盖增强。
本公开实施例的小区公共信号的覆盖增强方法，确定进行覆盖增强的增强小区公共信号的频域资源及时域资源；对所述增强小区公共信号对应的增强符号进行资源映射处理，得到所述增强小区公共信号的时域资源。根据所述增强小区公共信号的基本传输带宽，确定所述增强小区公共信号的频域资源；若所述频域资源为所述基本传输带宽，则在时域资源上，重复传输所述增强小区公共信号；若所述频域资源包含多组资源，且每组资源的频宽为所述基本传输带宽，则在频域资源上重复传输所述增强小区公共信号，或在所述频域资源和所述时域资源上重复传输所述增强小区公共信号，实现了小区公共信号的覆盖增强，使得处于深度衰落的用户或者装置也可以搜索并接入当前小区。
第三实施例
如图15所示，本公开的实施例还提供了一种小区公共信号的获取方法，应用于终端，包括：
步骤1501：确定用于传输增强小区公共信号的频域资源。
这里，基站在用于传输增强小区公共信号的频域资源上重复传输增强小区公共信号。
上述步骤1501具体包括：
步骤15011：在扩展带宽内进行同步信号检测处理，得到小区物理标识PCI。
具体的，在5MHz或者10MHz带宽内，进行同步信号检测处理，得到小区物理标识PCI。
步骤15012：根据所述PCI，确定增强小区公共信号的频域资源。
