Description

一种广播组播业务的传输方法、基站设备和用户设备 技术领域
本发明涉及通信技术领域,尤其涉及一种广播组播业务的传输方法、基站设备和用户设备。
背景技术
在通信系统中,通常会出现这一场景:同一地区多个用户接收相同的业务数据,比如热门球赛、热点新闻等等。这种情况下,为了节省频谱资源,长期演进系统(Long Term Evolution,简称为LTE)采用多媒体广播组播业务单频网(Multimedia Broadcast multicast service Single Frequency Network,简称为MBSFN)方式,同时向这多个用户传输相同的业务数据。如图1所示,图1是MBSFN发送的一个示例,图中带斜线的子帧是广播组播业务使用的子帧,其中有四种广播组播业务使用这些子帧发送,其它子帧则是单播业务使用的子帧。图中所有的子帧构成一个调度周期,在该调度周期的第一个子帧发送调度信息,用于指示这四个业务所在的子帧。比如业务B所对应的子帧编号为“#2”,表示业务B的数据到了“#2”子帧就结束了。
为了提高信号强度,3GPP所使用的MBSFN方式是由多个小区协同工作的,多个小区同时发送相同的内容,其信号在空中共同传输,用户设备(User Equipment,简称为UE)能同时收到来自多个小区的广播组播信号,这些信号相互叠加,从UE的角度看,相当于信号强度增加了。
MBSFN方式虽然能增强信号,但是要求多个小区协同工作,这就对灵活组网带来一些限制,为此,3GPP又引入了单小区点对多点(Single cell Point to multipoint,简称为SC-PTM)的方式,即单小区内点到多点的传输。顾名思义,这种方式是单小区的行为,无需多个小区协同工作。演进基站(E-UTRAN Node B,简称为eNB)在采用SC-PTM方式传输广播组播业务时,无需区分广播组播使用的子帧和其它子帧,每一个子帧都可以发送广播组播的数据。如图2所示,图2是SC-PTM发送的一个示例,基站事先为每个广播组播业务分配一个无线网络临时组标识(Multimedia Broadcast Multicast Service,简称为 G-RNTI),图中使用了G-RNTI 1和G-RNTI 2标识。基站需要发送某个业务时,先在物理下行控制信道(Physical Downlink Control Channel,简称为PDCCH)区域发送一个G-RNTI加扰的下行控制信息(Downlink Control Information,简称为DCI),用以指示该业务所对应的数据块在物理下行共享信道(Physical Downlink Shared Channel,简称为PDSCH)中的哪些时频上。UE在所有子帧盲检DCI,以搜索希望接收的广播组播业务,如果找到,再到对应的PDSCH区域的相应时频位置取出数据块。
这种传输方式要求UE不间断地监听PDCCH,以寻找要接收的广播组播业务,使得UE功耗大。特别是针对空闲态的UE,这类UE本来只需定期监听固定的PDCCH以接收寻呼消息,但是,UE一旦要接收广播组播业务的数据,在空闲态时也得监测所有子帧,大大增加了UE的功耗。

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,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。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前提下所获得的所有其他实施例,都属于本发明保护的范围。
在此部分,首先对本发明中各个实施例均涉及的一些基本概念进行说明。
本发明的技术方案具体可以应用于各种通信系统,例如:全球移动通讯(Global System of Mobile communication,简称为GSM)系统、码分多址(Code Division Multiple Access,简称为CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,简称为WCDMA)系统、通用分组无线业务(General Packet Radio Service,简称为GPRS)、长期演进(Long Term Evolution,简称为LTE)系统等,本发明实施例以LTE系统为例。具体应用于基站广播或组播业务的应用场景。如图3所示,基站可以给同一小区的多个UE发送广播组播业务的数据。具体可以参照图4-图6所示的方法实施例。
本发明实施例提供的用户设备(User Equipment,简称为UE)包括终端(Terminal)、移动台(Mobile Station,简称为MS)或移动终端(Mobile Terminal)等,该用户设备可以经无线接入网(Radio Access Network,简称为RAN)与一个或多个核心网进行通信,例如,用户设备可以是移动电话(或称为“蜂窝”电话)或具有移动终端的计算机等,例如,用户设备还可以是便携式、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数据。
本发明实施例提供的基站可以是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)。本发明实施例以LTE系统中的基站为例。
请参阅图4,图4是本发明实施例提供的一种广播组播业务的传输方法的流程图。本发明实施例是从基站角度描述的。如图4所示所述方法可以包括:
步骤S401,基站确定目标业务的调度周期的起始子帧。
假设,基站需要传输至少两种广播组播业务,由于基站传输每种广播组播业务的传输方法相同,本发明实施例仅以其中一种广播组播业务为例(即目标业务)阐述其广播组播业务的传输方法,其他广播组播业务的传输方法以此类推。
可选的,基站可根据公式offset=Ε mod Τ计算所述目标业务的偏移值,再根据公式(K*10+I)mod Τ=offset确定所述起始子帧,其中,offset为所述偏移值,E为所述目标业务的无线网络临时组标识,T为所述目标业务的调度周期,K为所述起始子帧的系统帧号,I为所述起始子帧的子帧号。
目标业务的调度周期可以根据目标业务能容忍的最大时延确定。可选的,可以将目标业务能容忍的最大时延确定为该目标业务的调度周期。假设,目标业务能容忍的最大时延为200ms,则可以确定目标业务的调度周期为200ms。
在LTE系统中,总共有1024个系统帧,系统帧号依次为0~1023,每个系统帧有10字子帧,子帧号依次为0~9。基站和UE对系统帧和系统帧内的子帧的编号方式事先约定好的。
基站和UE对目标业务的G-RNTI也是事先约定好的。
假设,目标业务的G-RNTI值为1284,调度周期为200ms,基站根据公式offset=Ε mod Τ可计算出所述目标的偏移值offset=1284mod200=84,再根据公式(K*10+I)mod Τ=offset可确定所述目标业务的起始子帧,即可确定目标业务的起始子帧可以为:第28号、48号、68号等等系统帧的第4号子帧。
步骤S402,基站根据所述目标业务在所述调度周期的调度情况确定调度信息。
基站事先可配置一个调度周期的目标业务。假设,该调度周期为200ms,由于每个子帧等于1ms,相当于该调度周期内存在200个子帧,而目标业务的数据可能只占用几个子帧,因此,其他子帧可用于调度其他的广播组播业务的数据。基站则根据所述目标业务在所述调度周期的调度情况确定调度信息。
所述调度情况包括所述目标业务在所述调度周期的调度位置和/或调度数量。当然,在一些可选的实施例中,所述调度情况也可以包括所述目标业务在接下来的K个调度周期中的调度位置和/或调度数量。
若所述调度情况包括所述目标业务在所述调度周期的调度位置,所述基站设备根据所述目标业务在所述调度周期的调度情况确定的调度信息包括位置指示信息,所述位置指示信息用于指示所述目标业务的数据在所述调度周期中的起始位置。具体的,假设,目标业务在一个调度周期的调度情况如图5所示,目标业务的数据的起始位置为“#3”子帧,基站可以通过位置指示信息指示所述目标业务的数据在所述调度周期中的起始位置为“#3”。需要说明的是,位置指示信息指示具体位置的方式本发明不限定。
若所述调度情况包括所述调度数量,所述基站设备根据所述目标业务在所述调度周期的调度情况确定的调度信息包括业务指示信息、数据量指示信息和/或传输块指示信息。
其中,所述业务指示信息用于指示所述调度周期中是否存在所述目标业务的数据。具体的,基站根据所述目标业务在所述调度周期的调度数量判断所述调度周期是否存在目标业务的数据。可选的,业务指示信息可用二进制表示调度周期中是否存在目标业务的数据,如用0表示没有目标业务的数据,用1表示有目标业务的数据;可选的,基站也可设置一个G-RNTI表,通过G-RNTI表表示调度周期中是否存在目标业务的数据,若G-RNTI表中存在G-RNTI表示有目标业务的数据,否则,表示没有目标业务的数据。
其中,所述数据量指示信息用于指示所述目标业务在所述调度周期中的数据量。具体的,基站根据所述目标业务在所述调度周期的调度数量确定所述数据量指示信息。假设,目标业务在一个调度周期的数据数量为400Bytes,基站可以通过数据量指示信息指示所述目标业务的数据量为400Bytes。需要说明的是,数据量指示信息指示具体数据量的方式本发明不限定。这样,UE在所述调度周期内如果已经获取到400Bytes的数据,就不再获取,降低了UE功耗。
其中,所述传输块指示信息用于指示所述目标业务的传输块在所述调度周期中的数量。具体的,基站可根据目标业务的数据量确定所述目标业务占用的传输块的数量,假设,目标业务在一个调度周期的传输块为3,基站可以通过传输块指示信息指示所述目标业务的传输块为3。需要说明的是,传输块指示信息指示传输块的具体数据的方式本发明不限定。这样,UE在所述调度周期内如果已经获取到3个传输块,就不再获取,降低了UE功耗。
应指出的是,步骤S401和步骤S402之间没有严格的先后执行顺序,还可以同时执行,本发明不限定。
当然,所述调度信息还可以包括一些调制解调所述目标业务的指示信息,如调制编码方式等等,一切方便UE接收所述调度周期的所述目标业务的指示信息都可以携带在所述调度信息中,本发明只例举了几种可能的实施方式,不能以此限定本发明。
步骤S403,基站通过所述起始子帧广播所述调度信息,以使UE根据所述调度信息获取所述调度周期中的所述目标业务的数据。
一种可选的实施方式中,所述调度信息可以为MAC层的控制信令或无线资源控制信令,且若所述调度信息为MAC层的控制信令或无线资源控制信令,所述调度信息是携带在所述起始子帧的物理下行共享信道PDSCH发送的,并通过下行控制信息DCI指示所述调度信息在所述PDSCH的位置。
具体实现中,可以通过所述目标业务的G-RNTI指示所述调度信息在所述PDSCH的位置,G-RNTI在起始子帧的哪个时隙,该时隙则为调度信息的位置;若基站通过所述起始子帧广播至少两个业务的调度信息,一种方式,可以通过各个业务的G-RNTI指示对应的调度信息在所述PDSCH的位置,假设,业务A的调度周期为200ms,业务B的调度周期为400ms,且业务A和业务B的偏移值都为0,即业务A和业务B的起始子帧部分相同,此时,可以通过业务A的G-RNTI指示业务A的调度信息在PDSCH的位置,通过业务B的G-RNTI指示业务B的调度信息在PDSCH的位置,两份指示相互独立;另一种方式,可以通过约定好的某一个公共的G-RNTI指示所述两份调度信息在所述PDSCH的位置。
在另一种可选的实施方式中,所述调度信息可以为物理层指示,若所述调度信息为物理层指示,所述调度信息是携带在所述起始子帧的物理下行控制信道PDCCH发送的,比如:基站通过PDCCH发送一份用G-RNTI加扰的DCI,其中包含调度信息。
再进一步的,基站还可以通过所述调度周期的至少一个子帧发送停止指示信息,基站发送停止指示信息可以使UE根据该停止指示信息停止获取所述目标业务的数据,进一步为UE节约了耗电量。具体的,所述停止指示信息可以 携带在所述至少一个子帧的DCI、MAC Header或媒体控制单元MAC CE内。
在一种可选的实施方式中,所述停止指示信息可用于指示在当前子帧之后的N个子帧内是否存在所述目标业务的数据,其中,N是携带在停止指示信息中的。假设,目标业务在一个调度周期的调度情况如图5所示,即目标业务的数据携带在“#3”子帧和“#7”子帧,基站可以通过“#3”子帧发送停止指示信息,用于指示在“#3”子帧之后的3个子帧内不存在目标业务的数据,那么,UE在获取到“#3”子帧的数据后的3个子帧内停止检测,直到“#3”子帧的数据后的第4个子帧才重新开始检测,以获取第“#7”子帧中的数据,相比UE一直检测调度周期而言,进一步降低了UE功耗;
需要说明的是,N的具体值是根据实际情况确定的,不能以本实施例例举的结果限定本发明。
在另一种可选的实施方式中,所述停止指示信息可用于指示在所述调度周期的下一调度周期是否存在所述目标业务的数据。具体的,假设,目标业务的数据在当前调度周期已经全部调度,则下一调度周期不会继续调度目标业务的数据,基站可以通过停止指示信息指示在下一调度周期不存在目标业务的数据,那么,UE在下一调度周期不会继续检测目标业务的数据,相比UE一直检测每个调度周期而言,进一步降低了UE的功耗。
在其他可选实施例中,所述用于指示在所述调度周期的下一调度周期是否存在所述目标业务的数据的停止指示信息还可以携带在调度信息中发送。
在又一种可选的实施方式中,所述停止指示信息用于指示在所述调度周期中当前子帧之后的子帧内是否存在所述目标业务的数据。具体的,假设,目标业务的调度周期总共有100个子帧,而目标业务的数据携带在“#3”子帧,也就是说“#4”~“#99”子帧都不存在目标业务的数据,基站可以发送停止指示信息,用于指示在本调度周期中“#3”子帧之后的子帧内都不存在目标业务的数据,那么,UE在获取到“#3”子帧的数据后就停止检测,相比UE检测整个调度周期而言,进一步降低了UE的功耗。
在图4所示的实施例中,基站确定目标业务的调度周期的起始子帧,并根据所述目标业务在所述调度周期的调度情况确定调度信息,再通过所述起始子帧广播所述调度信息,以使UE可以根据所述调度信息获取所述调度周期中的 所述目标业务的数据,相比现有技术中,UE通过盲检测获取业务的数据而言,降低了UE的功耗。
请参阅图6,图6是本发明实施例提供的另一种广播组播业务的传输方法的流程图。本发明实施例是从UE角度描述的。如图6所示所述方法可以包括:
步骤S601,UE确定目标业务的调度周期的起始子帧。
UE根据公式offset=Ε mod Τ计算所述目标业务的偏移值,再根据公式(K*10+I)mod Τ=offset确定所述起始子帧,其中,offset为所述偏移值,E为所述目标业务的无线网络临时组标识,T为所述目标业务的调度周期,K为所述起始子帧的系统帧号,I为所述起始子帧的子帧号。
目标业务的调度周期可以根据目标业务能容忍的最大时延确定。可选的,可以将目标业务能容忍的最大时延确定为该目标业务的调度周期。假设,目标业务能容忍的最大时延为200ms,则可以确定目标业务的调度周期为200ms。当然,所述目标业务的调度周期也可以是基站指示的。
假设,目标业务的G-RNTI值为1284,调度周期为200ms,UE根据公式offset=Ε mod Τ可计算出所述目标业务的偏移值offset=1284mod200=84,再根据公式(K*10+I)mod Τ=offset可确定所述目标业务的起始子帧,即可确定目标业务的起始子帧可以为:第28号、48号、68号等等系统帧的第4号子帧。
步骤S602,UE在所述起始子帧接收基站广播的调度信息,所述调度信息是基站根据所述目标业务在所述调度周期的调度情况确定的;所述调度情况包括所述目标业务在所述调度周期的调度位置和/或调度数量。
一种可选的实施方式中,所述调度信息可以为MAC层的控制信令或无线资源控制信令,UE可以在所述起始子帧的PDSCH检测到所述调度信息,并根据DCI确定所述调度信息在所述PDSCH的位置。
具体实现中,UE可以通过G-RNTI确定所述调度信息在所述PDSCH的位置,G-RNTI在起始子帧的哪个时隙,该时隙则为调度信息的位置。一种方式,不同的业务通过不同的G-RNTI指示;UE可以通过检测所述目标业务的G-RNTI确定对应的调度信息在所述PDSCH的位置;另一种方式,可以通过约定好的某一个G-RNTI指示所述调度信息在所述PDSCH的位置。
在另一种可选的实施方式中,所述调度信息可以为物理层指示,UE可以在所述起始子帧的PDCCH通过盲检检测到所述调度信息。
再进一步的,UE还可以通过所述调度周期的子帧接收停止指示信息。其中,所述停止指示信息携带在所述至少一个子帧的DCI、MAC Header或媒体控制单元MAC CE内。
步骤S603,UE根据所述调度信息获取所述目标业务的数据。
在一种可选的实施方式中,所述调度信息包括位置指示信息,所述位置指示信息用于指示所述目标业务的数据在所述调度周期中的起始位置。UE可以根据所述位置指示信息确定所述目标业务的数据在所述调度周期的起始位置,并在所述起始位置处获取所述目标业务的数据。目标业务在一个调度周期的调度情况如图5所示,即目标业务的数据携带在“#3”子帧和“#7”子帧,UE可以通过位置指示信息指示所述目标业务的数据的起始位置为“#3”子帧。
在另一种可选的实施方式中,所述调度信息包括业务指示信息,所述业务指示信息用于指示所述调度周期中是否存在所述目标业务的数据。UE可以根据所述业务指示信息判断所述调度周期是否存在所述目标业务的数据,若是,UE则检测所述调度周期以获取所述目标业务的数据;否则,UE停止检测所述调度周期。
具体的,所述业务指示信息可用二进制表示,如用0表示没有目标业务的数据,用1表示有目标业务的数据;所述业务指示信息也可通过G-RNTI表表示,通过G-RNTI表表示调度周期中是否存在目标业务的数据,如G-RNTI表中存在G-RNTI表示有目标业务的数据,否则,表示没有目标业务的数据。
在又一种可选的实施方式中,所述调度信息包括数据量指示信息,所述数据量指示信息用于指示所述目标业务在所述调度周期中的数据量;UE可以获取所述调度周期中的所述目标业务的数据,直到所述目标业务获取到的数据量达到所述数据量指示信息指示的数据量时停止获取。具体实现中,UE可以从所述起始子帧开始一直检测所述调度周期以获取所述目标业务的数据,直到所述目标业务获取到的数据量达到所述数据量指示信息指示的数据量时停止获取。假设,数据量指示信息指示目标业务在一个调度周期的数据量为400Bytes,UE可以从所述起始子帧开始一直检测所述调度周期,直到所述目标业务获取 到的数据量达到400Bytes时停止检测。
在又一种可选的实施方式中,所述调度信息包括传输块指示信息,所述传输块指示信息用于指示所述目标业务的传输块在所述调度周期中的数量;UE可以获取所述调度周期中的所述目标业务的数据,直到所述目标业务的传输块获取到的数量达到所述传输块指示信息指示的数量时停止获取。具体实现中,UE可以从所述起始子帧开始一直检测所述调度周期以获取所述目标业务的数据,直到所述目标业务的传输块获取到的数量达到所述传输块指示信息指示的数量时停止获取。假设,所述传输块指示信息指示目标业务在一个调度周期的传输块为3,UE可以从所述起始子帧开始一直检测所述调度周期,直到所述目标业务的传输块获取到的数量为3时停止检测。
进一步的,在一个调度周期内,如果基站没有明确指示目标业务的数据所在的子帧,即调度信息不包括位置指示信息,UE可以从所述起始子帧开始一直检测所述调度周期以获取所述目标业务的数据,若检测到连续M个业务都不是所述目标业务,则停止检测所述调度周期。
在一个调度周期内,UE若检测到连续M个业务都不是所述目标业务,则认为本调度周期不再有目标业务的数据,而停止在本调度周期继续尝试获取。
其中M可以由协议规定,也可以由基站配置给UE。如果由基站配置,各个广播组播业务可以共用一个M值,也可为各个广播组播业务分别配置一个M值。
进一步的,UE若检测到停止指示信息,则可以根据所述停止指示信息判断是否停止获取所述目标业务的数据。
在一种可选的实施方式中,所述停止指示信息用于指示在当前子帧之后的N个子帧内是否存在所述目标业务的数据,其中,N是携带在停止指示信息中的。假设,目标业务的数据携带在“#3”子帧和“#7”子帧,停止指示信息可以携带在“#3”子帧,用于指示在“#3”子帧之后的3个子帧内不存在目标业务的数据,那么,UE在获取到“#3”子帧的数据后的3个子帧内停止检测,直到“#3”子帧的数据后的第4个子帧才重新开始检测,以获取第“#7”子帧中的数据,相比UE一直检测调度周期而言,进一步降低了UE的功耗。
在另一种可选的实施方式中,所述停止指示信息用于指示在所述调度周期 的下一调度周期是否存在所述目标业务的数据。假设,目标业务的数据在当前调度周期已经全部调度,则下一调度周期不会继续调度目标业务的数据,停止指示信息可以用于指示在下一调度周期不存在目标业务的数据,那么,UE在下一调度周期不会继续检测目标业务的数据,相比UE一直检测每个调度周期而言,进一步降低了UE的功耗。
在又一种可选的实施方式中,所述停止指示信息用于指示在所述调度周期中当前子帧之后的子帧内是否存在所述目标业务的数据。假设,目标业务的调度周期总共有100个子帧,而目标业务的数据携带在“#3”子帧,也就是说“#4”~“#99”子帧都不存在目标业务的数据,停止指示信息可以用于指示在本调度周期中“#3”子帧之后的子帧内都不存在目标业务的数据,那么,UE在获取到“#3”子帧的数据后就停止检测,相比UE检测整个调度周期而言,进一步降低了UE功耗。
在图6所示的实施例中,UE确定目标业务的调度周期的起始子帧,并在所述起始子帧接收基站广播的调度信息,再根据所述调度信息获取所述目标业务的数据,相比现有技术中,UE通过盲检测获取目标业务的数据而言,降低了UE的功耗。
