Abstract
本发明公开了一种信息传输方法、基站、用户设备及通信系统,能够提高系统信息传输成功率,从而保障MBMS的实现。方法包括:在指定时频资源上接收基站发送的系统信息,系统信息包括MBMS区域标识以及区域标识对应的MCCH时频资源信息;根据MBMS区域标识以及区域标识对应的MCCH时频资源信息,确定用于传输区域标识对应的MCCH的时频资源;根据用于传输区域标识对应的MCCH的时频资源,接收区域标识对应的MCCH。本发明实施例的方法,系统信息直接携带于时频资源,由于时频资源能够通过更多的信道进行传输,因此能够提高系统信息传输成功率,保障UE正常接收MBMS。
Description
本发明涉及通信领域,特别涉及一种信息传输方法、基站、用户设备及通信系统。
MBMS(英文全称为:Multimedia Broadcast Multicast Service,中文译文为:广播业务)通常是按照MBMS区域(MBMS area)来进行的,网络中的若干个小区(通常是相邻的小区)组成一个MBMS区域,同一个MBMS区域内的小区发送属于本MBMS区域的MBMS服务(service)。例如,如果一个MBMS区域提供CCTV1的电视节目,则这个MBMS区域之内的所有小区都提供CCTV1的电视节目。
基站(如eNB)将系统信息及其他信息一起携带于MIB(英文全称为:Master Information Block,中文译文为:)消息及SIB(英文全称为:System Information Block,中文译文为:)消息通过PBSH(英文全称为:Physical Broadcast Channel,中文译文为:物理层广播信道)及PDSCH(英文全称为:Physical Downlink Shared Channel,中文译文为:)发送到UE(英文全称为:User equipment,中文译文为:用户设备),UE解析MIB消息及SIB消息得到系统信息,根据系统信息记录的MCCH(英文全称为:MBMS Control Channel)的相关信息(如MCCH的位置)继续监听MCCH,接收MCCH传输的MBMS业务相关信息,从而实现正常接收MBMS业务。
随着通信技术的发展,出现了一些特殊的载波,这些载波上没有PBCH、PDSCH,或者UE无法确定PBCH、PDSCH的具体位置,所以在这些载波上无法传输MIB消息及SIB消息,从而导致传输系统信息失败,影响UE实现广播业务。
因此,如何通过其他途径传输系统信息,从而提高系统信息传输成功率,保障MBMS的实现,是当前需要解决的问题。

图8为本发明一实施例提供的一种通信系统的结构示意图。
为使本发明的目的、技术方案和优点更加清楚,下面将结合附图对本发明实施方式作进一步地详细描述。
应理解,本发明的技术方案可以应用于各种通信系统,例如:GSM(Global System of Mobile communication,中文译文为:全球移动通讯)系统、CDMA(Code Division Multiple Access,中文译文为:码分多址)系统、WCDMA(Wideband Code Division Multiple Access,中文译文为:宽带码分多址)系统、GPRS(General Packet Radio Service,中文译文为:通用分组无线业务)、LTE(Long Term Evolution,中文译文为:长期演进)系统、FDD(Frequency Division Duplex,中文译文为:长期演进频分双工)系统、TDD(Time Division Duplex,长期演进时分双工)、UMTS(Universal Mobile Telecommunication System,中文译文为:通用移动通信系统)等。
还应理解,在本发明实施例中,UE(User Equipment,中文译文为:用户设备)可称之为终端(Terminal)、MS(Mobile Station,中文译文为:移动台)、移动终端(Mobile Terminal)等,该用户设备可以经RAN(Radio Access Network,中文译文为:无线接入网)与一个或多个核心网进行通信,例如,UE可以是移动电话(或称为“蜂窝”电话)、具有移动终端的计算机等,例如,UE还可以是便携式、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音和/或数据。
在本发明实施例中,基站可以是GSM或CDMA中的基站(Base Transceiver Station,简称为“BTS”),也可以是WCDMA中的基站
(NodeB,简称为“NB”),还可以是LTE中的演进型基站(Evolutional Node B,简称为“eNB或e-NodeB”),本发明并不限定。为了描述方便,下述实施例将以基站eNB和用户设备UE为例进行说明。
本发明一实施例提供一种信息传输方法,如图1所示,该方法包括:
101、在指定时频资源上接收基站发送的系统信息,所述系统信息包括MBMS区域标识以及区域标识对应的MCCH时频资源信息。
本发明实施例中,系统信息为该UE实现MBMS业务所需的系统信息。
102、根据所述MBMS区域标识以及区域标识对应的MCCH时频资源信息,确定用于传输区域标识对应的MCCH的时频资源。
其中,MBMS区域标识可以预先获取或通过解调系统信息获取。一个系统信息中可以包括至少一个MBMS区域对应的MCCH时频资源信息,因此,可以通过UE所需要的MBMS区域,有针对性的确定该UE对应的用于传输区域标识对应的MCCH的时频资源。
103、根据所述用于传输区域标识对应的MCCH的时频资源,接收所述区域标识对应的MCCH。
上述实施例可以由用户设备(例如UE)实现。
上述本发明实施例的信息传输方法,将UE实现MBMS所需的系统信息直接携带于指定时频资源,通过指定时频资源向UE传输系统信息。与现有技术中实现MBMS的系统信息分散于MIB消息和SIB消息,MIB消息和SIB消息由固定的信道传输,当传输MIB消息和SIB消息传输失败时,影响UE实现MBMS相比,本发明实施例的方法,系统信息直接携带于时频资源,由于指定时频资源的传输比较灵活,因此能够提高系统信息传输成功率,保障UE正常接收MBMS。
本发明实施例中,可选的,上述步骤101中的指定时频资源为特定的子帧或特定的子帧集合;或者,所述指定时频资源为系统带宽中特定的频带或特定的频带集合;或者,所述指定时频资源为特定的子
帧中特定的频带的集合。
例如,以12个子帧为周期,该指定时频资源可以是第5个子帧;或,如果指定时频资源为特定的子帧集合,该子帧集合可以包括第5、6和10个子帧;或,系统带宽的中间6个PRB(英文全称为:Physical Resource Block,中文译文为:物理资源块)为该频带集合,该UE可以在系统带宽的中间6个PRB接收该系统信息;或,特定的子帧中特定的频带的集合可以是第5、6和10个子帧中任一个子帧的某几个PRB。
本发明实施例中,可选的,上述步骤101中的“在指定时频资源上接收基站发送的系统信息”包括下述步骤:101a、当所述指定时频资源为特定的子帧集合时,在所述特定的子帧集合中的每个子帧上检测所述基站发送的系统信息,当在所述特定的子帧集合中的一个或多个子帧上检测到所述系统信息时,接收所述系统信息。如,图2为本发明实施例的一个时频资源示例,如图2所示,以12个子帧为周期,每12个子帧中的第5,6,10个子帧的中间6个PRB为指定时频资源。该基站可以在第5,6,10个子帧的某一个子帧(例如第10个)的中间6个PRB中发送该系统信息,该UE可以在第5,6,10子帧的中间6个PRB进行盲检测(blind detection),接收该系统信息。
本发明实施例中,可选的,上述步骤101中,在指定时频资源上接收基站发送的系统信息之前,所述方法还包括:接收基站发送的第一指示信息,所述第一指示信息用于通知UE传输所述系统信息的指定时频资源的位置。UE可以通过接收该基站所广播的第一指示信息,以获知该基站在哪个指定时频资源上传输该系统信息。该接收第一指示信息的时机可以是UE在进入基站覆盖范围时接收,还可以是UE在接入基站时接收。
本发明实施例中,可选的,上述步骤101中,在指定时频资源上接收基站发送的系统信息,包括:在指定时频资源上接收基站每隔预
设周期发送的系统信息。基站可以每隔预设周期发送系统信息,以使得在任何时刻进入该基站覆盖范围内的UE能够获取到系统信息,以实现MBMS业务。
可选的,上述步骤101中,在指定时频资源上接收基站发送的系统信息包括:在第一指定时频资源上接收基站发送的第一系统信息,所述第一系统信息包括所述系统信息的第一部分和第二指示信息,所述第二指示信息用于通知UE传输所述系统信息的第二部分的时频资源的位置;
在所述系统信息的第二部分的时频资源上接收所述基站发送的第二系统信息,所述第二系统信息包括所述系统信息的第二部分。
在该基站通过该指定时频资源向该UE传输该系统信息时,通过该指定时频资源向该UE传输该系统信息的全部;或者,通过该指定时频资源向该UE传输该系统信息的一部分,该系统信息的一部分可以包含在第一指示信息中,该第一指示信息用于向该UE通知传输该系统信息剩余部分即第二部分的时频资源的位置,使得UE能够在第二部分的时频资源上接收第二系统信息,例如该第一指示信息可以指示传输系统信息剩余部分的子帧号。这样,可以使得该UE成功接收全部系统信息。
可选地,上述指定时频资源位于单播子帧,或者所述指定时频资源位于广播子帧,或者所述指定时频资源位于单播子帧和广播子帧。
具体地,该传输该系统信息的时频资源位于单播子帧时,该UE应用单播子帧的对应的CP长度进行解调;该传输该系统信息的时频资源位于广播子帧时,该UE应用长CP进行解调;传输该系统信息的时频资源位于单播子帧和广播子帧时,对于单播子帧部分的系统信息,该UE应用单播子帧的对应的CP长度解调,对于广播子帧部分的系统信息,该UE应用长CP进行解调。
通过上述系统信息的多种传输方式,该基站在分配向该UE传输该系统信息的指定时频资源,能够根据应用场景的变化实时调整时频
资源的分配,且,通过多种方式传输该系统信息,从而可以提高系统信息传输的成功率。
可选地,上述系统信息为当前UE所在小区特有;或者,上述系统信息为当前UE所在小区所在的MBMS区域特有。
进一步地,当所述系统信息为当前UE所在小区特有,在对所述系统信息进行解调时,使用采用所述当前UE所在小区标识(如小区ID)进行加扰的RS;或,当所述系统信息为当前UE所在小区所在的MBMS区域特有,在对所述系统信息进行解调时,使用采用所述当前UE所在小区所在的MBMS区域标识(如区域ID)进行加扰的RS。
可以只有部分的area上存在上述信息,也可以只有部分cell存在上述信息。
具体地,当使用该UE所在小区的cell-id(小区标识)进行加扰时,该UE可以在进行PSS/SSS同步过程中获取该cell-id,从而得到RS的加扰信息,实现正确解调该系统信息。
当使用该UE所在小区所在的MBMS区域的area id(区域标识)进行加扰时,所述UE可以通过下述两种方式获取该area id:
方式一:获取预先配置的至少一个MBMS区域标识。
该基站与该UE预先约定该area id为固定值,或者该area id的可能值。例如,预先约定area id是0,该UE可以根据area id为0生成DMRS,然后在该时频资源上进行盲检,实现正确解调该系统信息。
例如,可以约定存在MBMS业务小区中至少有一个area的area id是0,则该UE可以根据area id为0生成DMRS,然后在该时频资源上进行盲检,如果有MBMS业务,则UE可以解调出来。
方式二:检测同步信道,所述同步信道携带至少一个MBMS区域标识。
预先设定该UE所在小区所在的MBMS区域的同步信道,该基站应用该同步信道向该UE发送该area id,UE通过检测同步信道获取该
area-id,生成DMRS,然后在该时频资源上进行接收,实现正确解调该系统信息。
可选地,所述系统信息包括以下至少一种:
系统带宽信息;系统子帧位置;至少一个MBMS区域标识;所述至少一个MBMS区域的MCCH信息;所述至少一个MBMS区域的MCCH变化周期;所述至少一个MBMS区域的MCCH变化信息的传输位置。
需要说明的是,该至少一个MBMS区域包含该UE所在小区所在的MBMS区域,即该系统信息优先包含该UE所在小区所在的MBMS区域的系统信息。
进一步地,所述至少一个MBMS区域的MCCH信息包括:
当前UE所在小区所在的MBMS区域包含的至少一个小区,该至少一个小区中每个小区配置的MBMS区域,所述至少一个小区中每个小区配置的MBMS区域的MCCH信息。
例如,该UE所在小区所在的MBMS区域包含4个小区,小区标识分别为Cell1、Cell2、Cell3、Cell4,可以通过以下方式通知每个小区配置的MBMS区域的MCCH信息:Cell1配置的MBMS区域,Cell1配置的每个MBMS区域的id及MCCH信息;Cell2配置的MBMS区域,Cell2配置的每个MBMS区域的id及MCCH信息;Cell3配置的MBMS区域,Cell3配置的每个Cell1配置的id及MCCH信息;Cell4配置的MBMS区域,Cell4配置的每个MBMS区域的id及MCCH信息。
再例如,该UE所在小区所在的MBMS区域包含4个小区,小区标识分别为Cell1、Cell2、Cell3、Cell4,可以通过以下方式通知每个小区配置的MBMS区域的MCCH信息:四个小区中至少有一个小区配置了MBMS区域1,MBMS区域1的id及MCCH信息,配置MBMS区域1的小区为Cell1;四个小区中至少有一个小区配置了MBMS区域2,MBMS区域2的id及MCCH信息,配置MBMS区域2的小区为Cell2、Cell3。
这样,该UE获取到一个MBMS的系统信息,即可得知其所在的小区的配置的其他MBMS区域的系统信息。
这样,该UE在接收了上述信息之后,可以到指定位置接收其他MBMS区域的系统信息,得知其他MBMS区域的MCCH信息实现其他MBMS区域的广播业务。
上述举例为该系统信息为该UE所在小区所在的MBMS区域特有时,该基站传输该系统信息的传输方法;该系统信息为该UE所在小区特有时,该基站传输可以采用现有的方法传输该系统信息。
上述本发明实施例的信息传输方法,将UE实现MBMS所需的系统信息直接携带于指定时频资源,通过指定时频资源向UE传输系统信息。与现有技术中实现MBMS的系统信息分散于MIB消息和SIB消息,MIB消息和SIB消息由固定的信道传输,当传输MIB消息和SIB消息传输失败时,影响UE实现MBMS相比,本发明实施例的方法,系统信息直接携带于时频资源,由于指定时频资源的传输比较灵活,因此能够提高系统信息传输成功率,保障UE正常接收MBMS。
