Abstract
本发明提供了一种信令消息的发送、检测装置、传输系统,其中,该方法包括:确定N组同步信号,以及所述N组同步信号对应的发送资源,N>=1;确定M套与所述N组同步信号关联的第一类信令消息,M<=N;确定所述M套第一类信令消息的发送资源位置;在所述发送资源和所述发送资源位置上分别发送所述N组同步信号和所述第一类信令消息。通过本发明,解决了相关技术中采用宽波束发送时导致广播信道的覆盖和效率问题。
Description
本发明涉及通信领域,具体而言,涉及一种信令消息的发送、检测装置、传输系统。
在无线通信系统中,开机后终端会进行小区搜索,进行同步序列的检测。完成小区搜索的过程之后,UE已经与小区取得下行同步,得到小区的PCI以及获得了子帧及系统帧的同步。接着,UE需要获取到小区的系统信息(System Information),这样才能知道该小区是如何配置的,以便接入该小区并在该小区内正确地工作。在4G长期演进(Long-Term Evolution,简称为LTE)系统中,小区的系统信息是在物理层广播信道中进行发送;4G中物理层广播信道发送的系统消息是小区级别的信息,即对接入该小区的所有UE生效。系统信息可分为Master Information Block(MIB)和多个System Information Block(SIB),每个系统信息包含了与某个功能相关的一系列参数集合。系统信息一些具体类型如表1示:
表1
并不是所有的SIB都必须存在。例如对于运营商部署的基站而言,就不需要SIB9;如果某小区不提供MBMS,就不需要SIB13。小区会不断地广播这些系统信息。
MIB中包含一些非常重要的广播消息,MIB会在物理信道PBCH(Physical Broadcast CHannel)上传输。LTE中PBCH上发送MIB的发送端处理过程如图1所示,图1(a)是本发明相关技术中LTE中PBCH上发送MIB的发送端处理过程示意图一,图1(b)是本发明相关技术中LTE中PBCH上发送MIB的发送端处理过程示意图二,图中,PCFICH,PHICH,PDCCH,PBCH等都为的信道。
SIB消息会在数据信道上传输,其发送资源会在公有控制信道(对应于PDCCH的common search space)上进行配置指示;
SIB1消息的发送周期为80ms其他系统消息的发送周期由SIB1配置,见36.331的IE:SystemInformationBlockType1字段:SchedulingInfoList
需要说明的是,前面只是介绍了相关技术LTE中的部分系统消息,在后续的LTE标准版本演进中,可能会增加一些其他类型的系统消息;在其
他的系统及其他系统的演进中,系统消息的类型可能会有一些差别,名称方面也可能有变化;
相关技术中的LTE系统中广播信道采用射频宽波束进行发送,申请人发现,由于天线数目的增多,以及高频的应用,一个趋势是采用窄波束进行传输,采用宽的波束可能无法满足覆盖要求也不能充分发挥多天线优势。引入射频波束后,原来的只需要一个宽波束发送的信道或信号即可覆盖整个小区,变为了需要多个窄波束的同步信号的进行发送,如图2所示,图2是本发明相关技术中的宽波束和窄波束的发送示意图。
相关技术中的方式仍然采用宽波束发送,会带来广播信道的覆盖和效率问题。
针对相关技术中存在的上述问题,目前尚未发现有效的解决方案。

实施例3
本实施例是根据本发明的可选实施例,用于结合具体的场景对本申请进行详细说明,本发明的相关技术中的方式仍然采用宽波束发送,会带来广播信道的覆盖和效率问题;另外,如果广播信道目前包括的一些消息和可能新增的一些信息,存在面向不同范围用户的需求,比如面向不同范围UE组的一些配置消息;因此需要新的广播或组播信息发送方法;本实施例包括多个具体实施例:
具体实施例A:
在基于射频波束扫描的同步信号发送方式中,图10是本发明实施例的发送同步信号的扫描示意图,同步信号在不同的时刻使用不同的射频波束向对应的方向进行发送,由于同步信号一般要保障全面的覆盖,所以扫
描的范围一般是小区的覆盖范围;波束越窄,增益越大覆盖越广,但需要的扫描波束越多,相应的时间越长;
这种扫描方式是简单的给出了单个发射通道,射频波束时分的情况,如果有多个发送通道,也可以进行其他的波束复用方式;
发送端需要确定N组同步信号以及所述N组同步信号对应的发送资源;一般N组同步信号对应于N种不同的发送资源配置;资源类型除了前面提到的时域符号和波束资源,也可以是天线端口资源或称为天线资源;频域资源;序列资源;等;例如,使用不同波束发送的同步信号可以用不同的天线端口进行区分;使用不同波束发送的同步信号也可以用不同的频域资源进行区分;使用不同波束发送的同步信号也可以在不同的序列资源上进行区分;
在下行,终端需要接收很多重要信息;这些重要信息主要包括:系统参数,例如物理层的一些重要配置信息如带宽配置、帧结构、numerology参数,接入参数,信道配置、等等;除了传统了4G中的些参数,这里还应该包括5G中会被新引入的一些物理层配置参数;系统消息不限于物理层的配置信息,还可以是高层的配置信息;
这些参数一般在物理层广播信道PBCH上传输,或者在物理层控制信道PDCCH上指示其传输位置,在物理层数据信道中传输;可以看出在PBCH上传输时一般直接发送信息内容本身,如果在控制信道上传输,则是传输一个传输指示信息而不是参数本身;这些消息在4G中是以小区广播方式发送的,在5G中则可能是小区广播或扇区组播方式发送的;组播方式不是面向所有小区的内的用户,只能面向部分用户构成的用户组;
对于上述这些信息,我们统一称呼为第一类信令,本发明提到的第一类信令包括:
-系统参数/广播参数/组播参数的配置消息;
-指示系统参数在物理层传输配置的物理层控制消息;
-在物理广播或组播信道中发送的信令配置消息;
-在物理控制信道中发送的信令配置消息(CSS/USS)
第一类信令如何发送是本发明需要解决的一个问题;我们提出了以下的一些方式来发送第一类信令:
第一种方式是同步信道与传输第一类信令的信道进行关联绑定,这里的关联关系包括:
-部分或全部第一类信令消息的传输与同步信号传输存在参考解调关系;
-部分或全部第一类信令消息的传输与同步信号的传输对应相同的(收/发)波束/虚拟扇区/端口/天线/传输节点;
-部分或全部第一类信令消息的传输信号与同步信号的传输信号具有准共位置关系;
部分或全部第一类信令消息的加扰方式与同步信号使用的发送资源位置(序列,位置,波束,扇区,天线,端口等)存在关联关系;
具体实施例A-1
第一类信令的信道对应的总的传输资源集合可能是一个较大的的资源集合,比如S个波束;或者是S个序列;或者是S个虚拟扇区,或者是S根天线,或者是S个时域符号组,或者是S个频域资源块等等;S为一个大于0的整数;
但是,为了获得更好的传输效率、鲁棒性以及配置的灵活性,可与根据一些方式对第一类信令消息确定其发送粒度,所谓的划分发送粒度的例子为表2,表2是本发明实施例的划分发送粒度表:
表2
一般来说S1S2Sn都是可以被S整除的,如果不能整除则有一套信令发送的资源数是取模(Mod)确定
不同的第一类信令可以有不同的发送粒度配置,对应不同的“每套信令发送资源”和“最大的可以发送的信令套数”。
其中划分方式可以是根据第一类信令消息的类型;
一个简单的例子是,对于一些基本系统参数,如系统带宽信息,可以只发送一套,所有的波束均发送相同的内容;而一些其他消息,如物理随机接入信道(Physical Random Access Channel,简称为PRACH)配置等,可以不同的波束发送不同的配置,也就是说同一套参数信息的发送粒度是不同的;
还有一个例子是,直接通知参数的第一类信令消息的发送套数配置x套,x>=1;而指示参数在物理层传输配置的物理层控制消息的发送套数配置y套,y>x;也就是说,直接通知参数的第一类信令消息的发送资源(e.g波束)数大于指示参数在物理层传输配置的物理层控制消息的发送资源(e.g波束)数,
还有一个例子是,在物理广播或组播信道中发送的信令配置消息的发送套数配置x套,x>=1;而在物理控制信道中发送的信令配置消息的发送套数配置y套,y>x;也就是说,直接通知参数的第一类信令消息的发送资源(e.g波束)数大于指示参数在物理层传输配置的物理层控制消息的发送资源(e.g波束)数,
除了上面提到的一些例子,还可以根据第一类信令消息的具体类型进行更细致的粒度划分,这样有更高的传输效率,比如下表3中给出的示例,表3是本发明实施例的根据第一类信令消息的类型进行划分的表格:
表3
| 第一信令消息的类型 | 发送粒度配置 |
| A | 1 |
| B | 2 |
| … | … |
| H | n |
第一信令消息的类型A,B……H可以是前面背景技术介绍中提到的各种消息,也可以包含5G中新引入的一些类型,粒度的配置可以是使用全部的资源,可以是使用1/2的资源,1/4的资源等等;本发明侧重于提出一种灵活粒度的消息发送方法;图11是根据本发明实施例的不同第一类消息子类型对应不同发送资源与发送参数套数的示意图。
各种不同子类型的第一类信令的发送粒度可以是由该子类型的特点决定,有不同的覆盖范围和面向的UE群组;
前面提到的发送粒度预先确定的方式,这种比较适合与初始接入的UE;发送粒度也可以是信令配置的,比较适合与非初始接入的情况,比如小区切换的情况,可以由之前的小区进行一些信令配置通知第一类信令消息的发送粒度;还有一种情况是低频辅助高频的情况,在低频的小区进入通信获取上述粒度的配置信息,然后再去高频进行同步接入;
发送端可以通过其他载频/小区的发送指示多种类型的第一类信令消息与多组同步信号关联关系的配置参数给接收端;比如指示某种子类型的第一类信令消息与一个或一组同步信号的关联关系,如果是一组,需要通知一组信号中包含的同步信号的数目;
所述第一类信令消息的扰码可以根据与其绑定同步信号所使用的资源索引来确定;第一类信令加扰时会使用一个扰码,该扰码初始化时,会有一个初始化参数,这个参数可以是由与该第一类信令消息其绑定同步信号所使用的资源索引来确定的。
具体实施方式A-2:
本实施方式用于说明实施例A中涉及的M套第一类信令消息的发送资源位置以及与其关联的同步信道的发送资源位置的关系;
一般来说第一类信令消息的发送资源与其关联的同步信道的发送资源进行频分和/或时分,具体的有以下一些方式:
方式1:第一类信令消息的发送位置位于与其绑定的同步信号的相同时域符号;图12是根据本发明实施例的第一类信令消息与同步信号的关联示意图,如图12所示,给出了两个具体例子其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波;如图12所示,其中横轴对应的维度是时域,比如正交频分复用(Orthogonal Frequency Division Multiplexing,简称为OFDM)符号,纵轴对应的维度是频域,比如子载波;
第一类信令消息与同步信号在相同的OFDM符号,与同步信号进行频分,具体的有几种情况,分别对应图12的3张图,在同步信号的单侧有两种情况,在同步信号的双侧有两种情况;较佳的,这里的第一类信令消息应该是与同步信号相邻的;
方式2:第一类信令消息的发送位置位于与其绑定的同步信号的相同时域符号以及与其绑定的同步信号之后的X1个时域符号;较佳的这X1个时域符号为连续的时域符号;图13是本发明实施例的第一类信令消息的发送位置与同步信号在时域的关系图一,如图13所示,是一种比较典型的例子,其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波;
除了这种情况,同步信号所在的符号,其传输第一类信令消息和同步信号的带宽可以比后面的传输第一类信令消息的带宽小一些。
方式3:第一类信令消息的发送位置位于与其绑定的同步信号的相同时域符号以及与其绑定的同步信号之前的X2个时域符号;更进一步的所述X2个时域符号为连续的时域符号,图14是本发明实施例的第一类信令消息的发送位置与同步信号在时域的关系图二,一个典型的例子如图14所
示,其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波。
方式4:第一类信令消息的发送位置位于与其绑定同步信号的相同时域符号以及与其绑定的同步信号之后的X1个时域符号以及与其绑定的同步信号之前的X2个时域符号;更进一步的所述X1,X2个时域符号为连续的时域符号;图15是本发明实施例的第一类信令消息的发送位置与同步信号在时域的关系图三,一个典型的例子如图15所示,其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波。
方式5:第一类信令消息的发送位置位于与其绑定的同步信号之后或之前的第Y1个时域符号;其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波;图16是本发明实施例的第一类信令消息的发送位置与同步信号在时域的关系图四。
较佳的,Y1个时域符号的位置为与所述绑定的同步信号相邻的Y1个时域符号;
但也可以是的不相邻的情况,图17是本发明实施例的第一类信令消息的发送位置与同步信号在时域的关系图五。
对于后面的两种情况这里Y1个时域符号的位置根据所述绑定的同步信号的资源索引确定;因为不同的索引的同步信号与第一类信令消息的间隔时间长度不是完全一样的,需要根据索引及第一类信令消息占用的OFDM符号数目才能确定间隔时长;
发送端可以通过同步信号指示中第一类信令消息的映射信息,包括带宽/位置/复用方式等信息;可以通过同步信号的位置,使用的序列,或者同步信号中携带的信息内容来指示所述映射信息;
发送端确定同步信号及第一类信令发送资源后在所述资源位置上发送所述第一类信息和同步信号。
具体实施方式A-3:
除了前面提到的一些情况外,还可以是一下的1套第一类信令消息对
多个同步信号的绑定关系,图18是本发明实施例的1套第一类信令消息对多个同步信号的绑定关系示意图,如图18所示,其中横轴对应的维度是时域,比如OFDM符号,纵轴对应的维度是频域,比如子载波:
具体实施例B:
发送端基站首先确定一些需要发送的第一类信令消息;这些第一类信令消息前面的实施例A中已经进行过介绍,包括以下信息中的一种或者多种:系统参数/广播参数/组播参数的配置消息;指示系统参数/广播参数/组播参数在物理层传输配置的物理层控制消息;在物理广播或组播信道中发送的信令配置消息;在物理控制信道中发送的信令配置消息(CSS/USS),本实施例中涉及的第一类信令消息与前面相同;
基站需要发送多种第一类信息消息,较佳的,基站可以将多种第一类信令消息分成多个组;一般来说需要至少存在两个组,即组数目大于等于2;
分组的方法可以是收发端进行约定的方式;比如协议规定好哪些第一类信令消息分为第一组,哪些第二类信令消息分为第二组,等等;
分组的方式可以根据第一类信令消息的类型,比如重要程度接近的信令消息分在同一组;
分组的方式可以根据第一类信令消息的周期;比如发送频率相同或接近的消息分在同一组
分组的方式可以根据第一类信令消息的开销大小;比如开销相近的分在同一组;
这里以2个组为例说明多组第一类信令消息的发送,更多的组的情况以此类推:
基站发送多组第一类信令消息,至少存在两组第一类信令消息的发送方法包括:
第一组消息在第一类信道上发送;第一类信道的发送带宽为发送端或
接收端约定;在第一类信道上发送第二类信道的传输参数配置配置信息;在第二类信道上的发送第二组消息;
更为具体的传输参数配置信息包括以下一种或多种:
第二类信道的发送端口:比如第二类信道使用多少个端口,具体是哪些端口,发送端口的位置信息等等;
第二类信道的发送天线配置:比如第二类信道使用哪些天线发送,天线拓扑,架构等信息;
第二类信道的发送扇区配置:比如第二类信道使用哪些发送扇区发送,数目及扇区ID;
第二类信道的发送波束配置:比如第二类信道使用哪些发送波束发送,数目及波束ID,波束权值等信息;
第二类信道的传输技术配置:比如是使用预编码还是分集技术;
第二类信道的时域资源大小/位置配置;比如其使用了多少OFDM符号,以及具体是哪些OFDM符号;
第二类信道的频域资源大小/位置配置;比如其使用了多少子载波,以及具体是哪些子载波
第二类信道的功率配置;比如,其发射功率相对于同步信号的发送功率偏置;或者其发送功率相对于其参考解调导频的发送功率偏置;或者是直接通知其发送功率的数值;
第二类信道的对应的导频配置;比如其参考解调导频的位置、密度、功率、端口数目、与其他信号的复用关系等信息
还可以包括第二类信道的时频资源映射配置;
较佳的所述第一类信道为第一物理广播或组播信道,第二类信道为第二物理广播或组播信道;图19是本发明实施例的第二类信道的时频资源映射配置示意图,图19中给出了两种情况。
图19只给出了2个,除了前面的图19中所示,另外一种较佳的方式
为,第一类信道为物理广播或组播信道,第二类信道为公有控制信道;
考虑到第一类信道携带的信息在接收端进行检测时需要一定的时间,如果第一类信道携带第二类信道的配置信息,那么在检测出第一类信道携带的信息之前,第二类信道无法正确的接收和检测,因此需要预留一定的时间,因此,第一类信道和第二类信道间的时间至少间隔Ts,Ts可以为绝对时间单位毫秒纳秒等,也可以是以OFDM符号数目为单位;
为了充分的利用资源,并且保障足够的时间间隔,较佳的可以向前面图19中所示的,在间隔内发送同步信号或其他的第一类信道。
具体实施例C:
