Description

一种数据传输方法及设备 技术领域
本发明涉及通信领域,尤其涉及一种数据传输方法及设备。
背景技术
机器类型通信(Machine Type Communication,MTC)是一种通过蜂窝网络进行数据传输的机器与机器(Machine to Machine,M2M)的通信,其主要应用于智能交通、智能电网、智能家居等领域,在这些领域中,MTC终端多部署在有限封闭的空间,如车内、地下室等特殊通信环境,与普通通信环境相比,其接收到的信号将会附加20dB的穿透损耗,也就是说,这种环境下的通信质量不好,MTC终端接收数据的成功率较低。目前,可以通过引入覆盖增强(Coverage enhancement)技术,来提高MTC终端接收数据的成功率。
另外,现有的MTC只支持单播通信模式,即每个MTC终端都要单独与基站建立通信链路,以便接收来自基站的数据。在这种单播通信模式下,当基站有软件升级等群组类型的多播业务数据需下发到群组内的所有MTC终端时,需要分别通过与每个MTC终端建立的通信链路向相应的MTC终端发送多播业务数据,这样会导致基站的资源耗损较为严重,也会使得网络负担加重,尤其在群组内包括的MTC终端的数量较大时,上述问题尤为突出。为了降低基站的资源损耗,减轻网络负担,MTC中可以引入一种单小区点对多点通信(Single Cell Point to Multi-point,SC-PTM)技术。在这种技术下,接收同一多播业务数据的一组MTC终端会使用相同的下行配置来接收数据,即该组MTC终端仅会与基站建立一条共享的通信链路,这样,当基站有多播业务数据需下发时,仅需通过该共享的通信链路便可以向群组内的所有MTC终端发送该多播业务数据,这样基站的资源耗损便得到降低,网络负担也得以减轻。但是,SC-PTM 技术目前并不支持覆盖增强技术,即在引入SC-PTM技术后,MTC终端接收数据的成功率仍然较低。
因此,如何提高引入SC-PTM技术后的MTC终端接收数据的成功率已成为本领域技术人员研究的重点课题。

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。
本文中术语“和/或”,仅仅是一种描述关联对象的关联关系,表示可以存在三种关系,例如,A和/或B,可以表示:单独存在A,同时存在A和B,单独存在B这三种情况。另外,本文中字符“/”,一般表示前后关联对象是一种“或”的关系。
为了降低MTC中基站的资源耗损,减轻网络负担,需要在MTC中引入一种SC-PTM技术,SC-PTM技术是一种利用共享资源信息 同时向多个MTC终端传输相同数据的技术,在该技术下,接收同一多播业务数据的一组MTC终端与基站之间建立有一条共享的通信链路,即共享一条下行传输信道,具体如图1所示,SC-PTM技术中有一个控制信道,即单小区多播控制信道(Single Cell Multi-cast Control Channel,SC-MCCH),一个数据信道,即单小区多播业务信道(Single Cell Multi-cast Traffic Channel,SC-MTCH),这两个信道均映射到下行共享信道(Downlink Shared Channel,DL-SCH)上,这样,当基站有多播业务数据需要下发时,可以先通过SC-MCCH向群组内的所有MTC终端发送控制信息(该控制信息中可以包括多播业务数据的标识和接收多播业务数据发送的时间),然后通过SC-MTCH向群组内的所有MTC终端发送多播业务数据,从而降低基站的资源耗损,减轻网络负担。但目前的问题是,即使引入SC-PTM技术,能够降低基站的资源耗损,减轻网络的负担,但是其目前并不支持覆盖增加技术,因此在直接引入SC-PTM技术到MTC中时,MTC终端接收数据的成功率仍然较低,为了提高MTC终端接收数据的成功率,本发明实施例提供了一种数据传输方法,其基本原理是:基站设备向终端设备发送用于控制多播业务数据的重复传输的第一控制信息,并根据第一控制信息向终端设备发送多播业务数据,使得终端设备可以根据接收到的第一控制信息接收基站设备重复发送的多播业务数据,以提高终端设备接收多播业务数据的成功率。这样,在引入SC-PTM技术的MTC中,MTC终端便可以通过根据接收到的第一控制信息接收基站重复发送的多播业务数据,从而提高了MTC终端接收数据的成功率。
需要说明的是,本发明实施例中所述的重复传输指的是将信息重复发送。

图5为本发明实施例提供的另一种数据传输方法的流程图,如图5所示,该方法可以包括:
为了提高引入SC-PTM技术的MTC中终端设备接收数据的成功率,本发明实施例提出了一种数据传输方法,为了便于本领域技术人员的理解,下面将对终端设备接收多播业务数据的一般过程进行具体描述:
401、基站设备向终端设备发送系统消息。
其中,该系统消息中可以包括用于终端设备完成多播业务数据接收所需的配置信息。
402、终端设备接收基站设备发送的系统消息。
403、基站设备向终端设备发送修改通知。
其中,该修改通知用于通知第一控制信息发生改变,修改通知中携带有第一RNTI。所述携带实质是发送修改通知的第三PDCCH或第三MPDCCH使用第一RNTI进行加扰。当用于控制多播业务数据的重复传输的信息,即第一控制信息发生改变时,基站设备可以向终端设备发送修改通知以便通知终端设备重新获取第一控制信息,进而重新获取多播业务数据。这里需要说明的是,一种情况,并不是第一控制信息中的任何信息发生改变就发送修改通知,可以是第一控制信息中的部分信息发生改变时才发送修改通知。例如,当第一控制信息中携带的多播业务数据的类型信息发生改变时,发送修改通知,其他信息发生改变时,不发送修改通知。或者,例如,只是第一控制信息中增加了新的多播业务类型时,才发送修改通知,其他情况不发送修改通知,等等。当然,若用于控制多播业务数据的重复传输的信息,即第一控制信息未发生改变,则无需执行步骤403,但终端设备依然需要盲检发送修改通知的第三PDCCH或第三 MPDCCH,以确认是否有修改通知。
进一步的,为了能够提高终端设备接收多播业务数据的成功率,基站设备可以向终端设备重复发送修改通知,可以用系统消息控制修改通知的重复传输。具体的,当系统消息用于控制修改通知的重复传输时,基站设备可以根据系统消息向终端设备重复发送修改通知。其中,系统消息中可以包括第二配置参数,以用来控制修改通知的重复传输,该第二配置参数可以包括以下至少一项:第二偏移量、第二调度周期、第二起始时刻、第二终止时刻、第二重复次数、第二重复模式、第二频率信息。
其中,在上述第二配置参数包括的参数中:
1、第二调度周期,当第二调度周期用系统帧号表示时,可以确定发送该修改通知的系统帧号,该系统帧号是一个调度周期内发送该修改通知的起始系统帧。例如,如图6A所示,第二调度周期为16(单位:帧),根据公式SFN mod第二调度周期=0(SFN为系统帧号,mod表示取余运算),便可以确定出发送修改通知的系统帧号为0、16、32、48、64、80、96等等。也就是说,当基站设备需要发送修改通知时,可以根据第二调度周期确定当前的系统帧是否需要发送修改通知,如,当前的系统帧号为16,那么根据公式SFN mod第二调度周期=0便可以确定当前的系统帧16需发送修改通知。
或者,当第二调度周期使用子帧号来表示时,可以确定发送该修改通知的系统帧号和起始子帧号。例如,如图6B所示,第二调度周期为25(单位:子帧),根据公式(SFN*10+子帧号)mod第二调度周期=0,便可以确定出发送修改通知的系统帧号为0、2等等,且系统帧0对应的起始子帧号为0,系统帧2对应的起始子帧号为5。也就是说,当基站设备需要发送修改通知时,可以根据第二调度周期确定当前的系统帧是否需要发送修改通知,且确定出在当前系统帧的哪个子帧上开始发送,即确定出起始子帧号,如,当前的系统帧号为2,那么根据公式(SFN*10+子帧号)mod第二调度周期=0便可以确定当前的系统帧2需发送修改通知,且起始子帧号为5。
2、第二偏移量,当第二偏移量用系统帧号表示时,可以与第二调度周期一起来确定发送该修改通知的系统帧号。例如,如图6C所示,第二调度周期为16(单位:帧)第二偏移量为1(单位:帧),根据公式SFN mod第二调度周期=第二偏移量(SFN为系统帧号,mod表示取余运算),便可以确定出发送修改通知的系统帧号为1、17、33、49、65、81、97等等。也就是说,当基站设备需要发送修改通知时,可以根据第二调度周期和第二偏移量确定当前的系统帧是否需要发送修改通知,如,当前的系统帧号为33,那么根据公式SFN mod第二调度周期=第二偏移量便可以确定当前的系统帧33需发送修改通知。
或者,当第二调度周期和第二偏移量都使用子帧号来表示时,可以一起来确定发送该修改通知的系统帧号和起始子帧号。例如,如图6D所示,第二调度周期为25(单位:子帧)、第二偏移量为5(单位:子帧),根据公式(SFN*10+子帧号)mod第二调度周期=第二偏移量,便可以确定出发送修改通知的系统帧号为0、3、5等等,且系统帧0对应的起始子帧号为5,系统帧3对应的起始子帧号为0,系统帧5对应的起始子帧号为5。也就是说,当基站设备需要发送修改通知时,可以根据第二调度周期确定当前的系统帧是否需要发送修改通知,且确定出在当前系统帧的哪个子帧上开始发送,即确定出起始子帧号,如,当前的系统帧号为3,那么根据公式(SFN*10+子帧号)mod第二调度周期=第二偏移量便可以确定当前的系统帧3需发送修改通知,且起始子帧号为0。
3、第二起始时刻,当只确定了发送修改通知的系统帧号时,可以使用第二起始时刻来确认起始子帧号,这时第二起始时刻用于确定传输修改通知的起始子帧号。此外,第二起始时刻还可以用于确定传输修改通知的起始符号,即在每次重复发送该修改通知的子帧里,具体从哪个符号开始发送该修改通知。第二终止时刻,指重复发送修改通知的最后一个帧位置和/或最后一个子帧位置和/或一个子帧中最后一个符号位置。
以上确定了发送该修改通知的系统帧号,和这个系统帧号里的起始子帧号,和重复发送该修改通知的子帧里,具体的起始符号。
4、第二重复次数,表示在一个调度周期里,重复发送该修改通知的次数。如1次,2次,…,N次,N为大于或等于1的整数,示例性的,如图6所示,表示第二重复次数为1次、2次、3次。
5、第二重复模式指的是重复传输修改通知(即该第三PDCCH或第三MPDCCH)的模式,例如,第二重复模式为每1个子帧传输一次修改通知,每2个子帧传输一次修改通知,…,每M个子帧传输一次修改通知,M为大于或等于1的整数,示例性的,如图7所示,表示第二重复模式为每1个子帧传输一次修改通知,每2个子帧传输一次修改通知,每3个子帧传输一次修改通知,根据上述确定的系统帧号和起始子帧号和第二重复次数和第二重复模式,便可以确定出在当前的系统帧上或当前的调度周期中的哪些子帧需要进行修改通知的传输。示例性的,如图8所示,假设当前的系统帧的系统帧号为5,起始子帧号为3,第二重复次数为2,第二重复模式为每3个子帧传输一次修改通知,那么根据第二重复次数和第二重复模式确定出在系统帧号为5的系统帧上的3号子帧和6号子帧上需进行修改通知的传输。其中,这里不限制重复传输该修改通知(即第三PDCCH或第三MPDCCH)的子帧一定位于一个系统帧内,即重复传输子帧可以扩展到后面的系统帧,这样就是确定在当前的调度周期中的哪些子帧重复发送修改通知。
6、第二频率信息,表示发送该修改通知(即第三PDCCH或第三MPDCCH)的频率信息,即在哪些频带上发送该修改通知,在MTC中,系统带宽被分成多个窄带,如6个物理资源块(Physical Resource Block,PRB),对应6×180kHz,则第二频率信息表示该修改通知具体在哪个6PRB上发送,该频率信息可以是具体的频率,即以Hz为单位,或是系统带宽分成多个窄带后的窄带的索引值(Narrow Band Index)。例如,如图8A所示,每种系统带宽都被分成若干个6PRBs,当终端设备接收某个基站设备的服务时,终端设 备通过系统消息即可获取到系统带宽,如10MHz(对应50PRB),此时系统带宽被分成8个窄带,第一个窄带为第2PRB到第7PRB,第二个窄带为第8PRB到第13PRB,依此类推。另外,不同系统带宽下,划分窄带的方法可能有所不同,但都可以对划分的窄带依次进行索引,如上述例子窄带索引依次为1、2、…、8,这样当基站设备配置在哪个窄带上发送修改通知时,可以直接通知终端设备窄带的索引值,即第二频率信息为索引值,如索引值为3,表示3对应的窄带,即是该系统带宽下,10MHz(对应50PRB),第14PRB到第19PRB的窄带。这样当终端设备收到此第二频率信息后,就可以在该指定的窄带上去接收修改通知。
需要说明的是,第二配置参数中具体包括的内容可以根据实际应用场景的需求进行选择,本发明实施例在此并不做具体限定。且,若用来控制修改通知的重复传输所需的参数不包括在第二配置参数中时,可以将用来控制修改通知的重复传输所需的参数预先配置在基站设备和终端设备中,也可以根据实际应用场景的需求采用其他的方式通知终端设备,本发明实施例在此并不做具体限制。
另外,针对第二配置参数中包括的第二重复次数和第二重复模式也可以用类似的参数替代,以确定在当前的系统帧上的哪些子帧需要进行修改通知的传输。例如,可以用重复间隔或重复周期代替第二重复模式,重复间隔指的是发送修改通知的两个子帧的间隔,如重复间隔为0个子帧,1个子帧,…,X个子帧,X为大于或等于0的整数,重复周期指的是在一个调度周期内重复发送修改通知的周期,如重复周期为1个子帧,2个子帧,…,Y个子帧,Y为大于或等于0的整数。示例性的,如图9所示,表示重复间隔为0个子帧(相应的重复周期为1个子帧)、1个子帧(相应的重复周期为2个子帧)、2个子帧(相应的重复周期为3个子帧)。再例如,还可以用重复时间代替重复第二重复次数,重复时间指的是从发送第一个修改通知到最后一个修改通知持续的时间,如,重复时间为1个子帧、2个子帧,3个子帧,…,Z个子帧,Z为大于或等于1的整 数。示例性的,如图10所示,表示重复时间为2个子帧、3个子帧、4个子帧,根据重复间隔、重复周期和第二重复模式中的一个,以及重复时间也可以确定出在当前的系统帧上的哪些子帧需要进行修改通知的传输。
示例性的,假设第二配置参数包括第二偏移量、第二调度周期(且第二调度周期和第二偏移量都使用子帧号来表示)、第二起始时刻、第二重复次数(Repetition Number)、第二重复模式(Repetition Pattern)和第二频率信息,此时基站设备根据系统消息向终端设备发送修改通知具体的可以为:基站设备可以先根据第二偏移量和第二调度周期,确定当前的系统帧是否为需发送修改通知的系统帧,若确定出当前的系统帧不是需发送修改通知的系统帧,则判断当前的系统帧的下一个系统帧是否为需发送修改通知的系统帧,若确定出当前的系统帧是需发送修改通知的系统帧,则基站设备根据第二偏移量、第二调度周期、第二起始时刻、第二重复次数和第二重复模式确定出需要在当前的系统帧或当前的调度周期内的哪些子帧和/或符号上发送修改通知,然后根据确定出的所有子帧号和/或符号,以及第二频率信息向终端设备发送携带有第一RNTI的修改通知,以便实现修改通知的重复发送。例如,第二偏移量为5(单位:子帧)、第二调度周期为25(单位:子帧)、第二重复次数为3次、第二重复模式为每2个子帧发送一次,且,当前的系统帧为7,此时基站设备根据系统消息向终端设备发送修改通知具体的可以为:基站设备可以先根据第二偏移量5和第二调度周期25,确定当前的系统帧7为需发送修改通知的系统帧,则基站设备根据第二偏移量5、第二调度周期25、第二重复次数3和第二重复模式每2个子帧发送一次确定出需要在当前的系统帧7的子帧0、子帧2、子帧4上发送修改通知(如图10A所示),然后根据第二频率信息,在系统帧号为7的子帧0、2、4上向终端设备发送携带有第一RNTI的修改通知,以便实现修改通知的重复发送。
其中,第一RNTI具体的可以为单小区修改通知无线网络临时 标识(Single Cell Notification Radio Network Temporary Identity,SC-N-RNTI),也就是说可以采用SC-N-RNTI对第三PDCCH或第三MPDCCH进行加扰,实现向终端设备通知第一控制信息发生改变的目的。
此步骤为可选步骤。
404、终端设备接收基站设备发送的修改通知。
其中,在终端设备对多播业务数据感兴趣时,终端设备直接接收第一控制信息(该第一控制信息可以携带在SC-MCCH中),不需要盲检携带修改通知的第三PDCCH或第三MPDCCH,当接收到的第一控制信息中不包含终端设备感兴趣的业务时,终端设备需要一直盲检发送修改通知的第三PDCCH或第三MPDCCH,因为当终端设备感兴趣的业务出现时,一定会引起第一控制信息的改变,这样基站设备一定会发修改通知,所以为了节约终端设备的功耗,此时,终端设备只需要盲检测携带修改通知的第三PDCCH或第三MPDCCH。若终端设备检测到修改通知,则读取携带在SC-MCCH中的第一控制信息。若还不包含感兴趣的业务,继续盲检测第三PDCCH或第三MPDCCH,若已经包含,则根据携带在SC-MCCH中的第一控制信息接收携带在SC-MTCH中的多播业务数据,接收多播业务数据时,终端设备会一直接收携带在SC-MCCH中的第一控制信息,这时不需要检测携带修改通知的第三PDCCH或第三MPDCCH。
进一步的,当基站设备根据系统消息向终端设备重复发送修改通知时,终端设备可以根据系统消息接收基站设备重复发送的修改通知,具体的,终端设备可以根据系统消息中包括的第二配置参数接收基站设备重复发送的修改通知。其中,对于第二配置参数的具体描述与步骤403中对第二配置参数的具体描述类似,本发明实施例在此不再详细赘述。
示例性的,按照步骤403中的例子,终端设备根据系统消息接收基站设备发送的修改通知具体的可以为:终端设备可以先根据第 二偏移量和第二调度周期,或只根据第二调度周期,确定当前的系统帧是否为需接收修改通知的系统帧,若确定出当前的系统帧不是需接收修改通知的系统帧,则判断当前的系统帧的下一个系统帧是否为需接收修改通知的系统帧,若确定出当前的系统帧是需接收修改通知的系统帧,则终端设备根据第二偏移量、第二调度周期、第二起始时刻、第二重复次数和第二重复模式确定出需要在当前的系统帧或当前的调度周期内的哪些子帧和/或符号上接收修改通知,然后根据确定出的所有子帧号和/或符号,以及第二频率信息接收基站设备发送携带有第一RNTI的修改通知,由于可以在多个子帧号和/或符号上重复接收修改通知,因此提高了终端设备接收修改通知的成功率。其中,当第一RNTI为SC-N-RNTI时,终端设备可以采用SC-N-RNTI对第三PDCCH或第三MPDCCH进行解扰,若解扰成功,则可以确定第一控制信息发生改变。
此步骤为可选步骤。
405、基站设备向终端设备发送第二控制信息。
其中,基站设备在向终端设备发送第一控制信息之前,可以先向终端设备发送第一控制信息的调度信息,即第二控制信息。
进一步的,为了能够提高终端设备接收多播业务数据的成功率,基站设备可以向终端设备重复发送第二控制信息,在一种可能的实现方式中,可以用系统消息控制第二控制信息的重复传输,具体的,当系统消息用于控制第二控制信息的重复传输时,基站设备可以根据系统消息向终端设备发送第二控制信息。其中,系统消息中可以包括第三配置参数,以用来控制第二控制信息的重复传输,该第三配置参数可以包括以下至少一项:第三偏移量、第三调度周期、第三起始时刻、第三终止时刻、第三重复次数、第三重复模式、第三频率信息。
另外,第三终止时刻,指的是重复发送第二控制信息的最后一个帧位置和/或最后一个子帧位置和/或一个子帧中最后一个符号位置第三偏移量还可以指示修改通知消息发送的最后一个子帧到发送 第二控制信息的起始子帧的偏移。
需要说明的是,本发明实施例中对于第三配置参数的具体描述与步骤403对第二配置参数的描述类似,本发明实施例在此不再详细赘述。另外,第三配置参数中具体包括的内容可以根据实际应用场景的需求进行选择,本发明实施例在此并不做具体限定。且,若用来控制第二控制信息的重复传输所需的参数不包括在第三配置参数中时,可以将用来控制第二控制信息的重复传输所需的参数预先配置在基站设备和终端设备中,也可以根据实际应用场景的需求采用其他的方式通知终端设备,本发明实施例在此并不做具体限制。
示例性的,假设第三配置参数包括第三偏移量、第三调度周期(且第三调度周期和第三偏移量都使用子帧号来表示)、第三起始时刻、第三重复次数、第三重复模式和第三频率信息。此时基站设备根据系统消息向终端设备发送第二控制信息具体的可以为:基站设备可以先根据第三偏移量和第三调度周期确定当前的系统帧是否为需发送第二控制信息的系统帧,若确定出当前的系统帧不是需发送第二控制信息的系统帧,则判断当前的系统帧的下一个系统帧是否为需发送第二控制信息的系统帧,若确定出当前的系统帧是需发送第二控制信息的系统帧,则基站设备根据第三偏移量、第三调度周期,第三起始时刻、第三重复次数和第三重复模式确定出需要在当前的系统帧或当前的调度周期的哪些子帧和/或符号上发送第二控制信息,然后根据确定出的所有子帧号和/或符号,以及第三频率信息通过第一PDCCH或第一MPDCCH向终端设备发送第二控制信息,以便实现第二控制信息的重复发送。
另外,在另一种可能的实现方式中,基站设备也可以直接根据重复传输修改通知的子帧和/或符号来进行第二控制信息的重复传输,也就是说,基站设备在向终端设备发送了修改通知之后,可以直接根据确定出的需要发送修改通知的子帧和/或符号上发送第二控制信息。在又一种可能的实现方式中,系统消息中可以包括一修正偏移量(这个修改偏移量可以包含在第三偏移量中)(该修正偏移 量指的是发送第二控制信息的起始子帧相对于发送修改通知的起始子帧的偏移量,该修正偏移量的单位可以是帧,也可以是子帧),当修正偏移量的单位是子帧时,基站设备向终端设备发送第二控制信息具体的可以是:基站设备根据该修正偏移量和确定出的需要发送修改通知的子帧和/或符号,确定出发送第二控制信息的子帧和/或符号,然后根据确定出的发送第二控制信息的子帧和/或符号发送第二控制信息。当修正偏移量的单位是帧时,基站设备向终端设备发送第二控制信息具体的可以是:基站设备根据该修正偏移量、起始子帧号和确定出的需要发送修改通知的子帧和/或符号,确定出发送第二控制信息的子帧和/或符号,然后根据确定出的发送第二控制信息的子帧和/或符号发送第二控制信息。
此步骤为可选步骤。
406、终端设备接收基站设备发送的第二控制信息。
其中,在基站设备向终端设备发送了第二控制信息之后,终端设备便可以接收基站设备发送的第二控制信息。
进一步的,在一种可能的实现方式中,当基站设备根据系统消息向终端设备重复发送第二控制信息时,终端设备可以根据系统消息接收基站设备重复发送的第二控制信息,具体的,终端设备可以根据系统消息中包括的第三配置参数接收基站设备重复发送的第二控制信息。其中,对于第三配置参数的具体描述与步骤405中对第三配置参数的具体描述类似,本发明实施例在此不再详细赘述。
示例性的,按照步骤405中的例子,终端设备根据系统消息接收基站设备发送的第二控制信息具体的可以为:终端设备可以先根据第三偏移量和第三调度周期,确定当前的系统帧是否为需接收第二控制信息的系统帧,若确定出当前的系统帧不是需接收第二控制信息的系统帧,则判断当前的系统帧的下一个系统帧是否为需接收第二控制信息的系统帧,若确定出当前的系统帧是需接收第二控制信息的系统帧,则终端设备根据第三偏移量、第三调度周期、第三起始时刻、第三重复次数和第三重复模式确定出需要在当前的系统 帧或当前的调度周期的哪些子帧和/或符号上接收第二控制信息,然后根据确定出的所有子帧号和/或符号,以及第三频率信息通过第一PDCCH或第一MPDCCH接收基站设备发送第二控制信息,由于可以在多个子帧号和/或符号上重复接收第二控制信息,因此提高了终端设备接收第二控制信息的成功率。
另外,在另一种可能的实现方式中,当基站设备直接根据重复传输修改通知的子帧和/或符号来进行第二控制信息的重复传输时,终端设备可以根据确定出的接收修改通知的子帧和/或符号,接收第二控制信息。在又一种可能的实现方式中,当基站设备根据修正偏移量(该修正偏移量可以包括在系统消息中,具体的,该修正偏移量可以包含在第三偏移量中)向终端设备重复发送第二控制信息时,基站设备可以根据该修正偏移量和确定出的需要接收修改通知的子帧和/或符号(或者,根据修正偏移量、起始子帧号和确定出的需要接收修改通知的子帧和/或符号),确定出接收第二控制信息的子帧和/或符号,然后根据确定出的接收第二控制信息的子帧和/或符号接收第二控制信息。
在本发明实施例中,优选的,为了减少终端设备获取到多播业务数据的时延,当第一控制信息发生改变时,无需执行步骤403和步骤404,而是通过采用第一RNTI对发送第二控制信息进行加扰,该第一RNTI用于对第二控制信息进行加扰,且用于指示第一控制信息发生改变,例如,该第一RNTI可以为SC-N-RNTI,具体的,基站设备可以采用第一RNTI,如SC-N-RNTI对第一PDCCH(或第一MPDCCH)进行加扰,然后通过采用第一RNTI加扰后的第一PDCCH(或第一MPDCCH)发送第一控制信息,当第一控制信息未发生改变时,步骤403和步骤404也是无需执行的,此时基站设备可以采用第二RNTI,如SC-RNTI对第一PDCCH(或第一MPDCCH)进行加扰,然后通过采用第二RNTI加扰后的第一PDCCH(或第一MPDCCH)发送第一控制信息。对于终端设备来说,其可以采用第一RNTI和第二RNTI分别对第一PDCCH(或第一MPDCCH)进行 解扰,若采用第一RNTI对第一PDCCH(或第一MPDCCH)解扰成功,则表明第一控制信息发生改变,此时需重新获取第一控制信息,以便重新获取多播业务数据,若采用第二RNTI对第一PDCCH(或第一MPDCCH)解扰成功,则表明第一控制信息未发生改变。或者,当第一控制信息发生改变时,无需执行步骤403和步骤404,而是在第二控制信息中增加一指示信息,该指示信息用于指示第一控制信息发生改变,这样当第一控制信息发生改变时,无需执行步骤403和步骤404,可以直接通过第二控制信息向终端设备通知第一控制信息发生改变,减少了终端设备获取到多播业务数据的时延。
此步骤为可选步骤。
407、基站设备向终端设备发送第一控制信息。
其中,在基站设备向终端设备发送了第二控制信息之后,基站设备可以向终端设备发送第一控制信息,第一控制信息指的是多播业务数据的控制信息。
进一步的,为了能够提高终端设备接收多播业务数据的成功率,基站设备可以向终端设备重复发送第一控制信息,在一种可能的实现方式中,用于控制第一控制信息的重复传输的参数全部包含在第二控制信息中,即采用第二控制信息来控制第一控制信息的重复传输,此时,具体的,基站设备可以根据第二控制信息向终端设备发送第一控制信息。其中,第二控制信息中可以包括第四配置参数,以用来控制第一控制信息的重复传输,并且,考虑到系统带宽的限制,第一控制信息可能需进行分段传输,因此,当第一控制信息不需进行分段传输时,该第四配置参数可以包括:第四偏移量、第四调度周期、第四起始时刻、第四终止时刻、第四重复次数、第四重复模式、MCS、TBS、第四频率信息,当第一控制信息需进行分段传输时,第四配置参数还可以包括:分段数、重复方式。
其中,第四终止时刻,指重复发送第一控制信息的最后一个帧位置和/或最后一个子帧位置和/或一个子帧中最后一个符号位置。此外,本文中,MCS包含调制方式和编码速率,一般MCS使用索引 值,索引不同的调制方式和编码速率。TBS,传输块大小,可以以比特为单位,或是索引一些比特为单位的值。
分段数指的是对第一控制信息需要进行分段的段数,如2段,…,A段,A为大于或等于2的整数,重复方式为依次间隔传输不同分段信息或将当前分段信息重复传输完成之后,再重复传输下一个分段信息。示例性的,如图11所示为分段数为2段,重复方式为依次间隔传输不同分段信息,第四重复次数为4次、第四重复模式为每2个子帧传输一次分段信息的示意图。如图12所示为分段数为2段,重复方式为将当前分段信息重复传输完成之后,再重复传输下一个分段信息,第四重复次数为4次、第四重复模式为每2个子帧传输一次分段信息的示意图。

示例性的,按照步骤409中的例子,终端设备根据第一控制信息接收基站设备发送的第三控制信息具体的可以为:终端设备可以先根据第五偏移量和第五调度周期确定当前的系统帧是否为需接收第三控制信息的系统帧,若确定出当前的系统帧不是需接收第三控制信息的系统帧,则判断当前的系统帧的下一个系统帧是否为需接收第三控制信息的系统帧,若确定出当前的系统帧是需接收第三控制信息的系统帧,则终端设备根据第五偏移量、第五调度周期、第五起始时刻、第五重复次数和第五重复模式确定出需要在当前的系统帧或当前的调度周期的哪些子帧和/或符号上接收第三控制信息,然后根据确定出的所有子帧号和/或符号,以及第五频率信息通过第二PDCCH或第二MPDCCH接收基站设备发送第三控制信息,由于可以在多个子帧号和/或符号上重复接收第三控制信息,因此提高了终端设备接收第三控制信息的成功率。
此步骤为可选步骤。
411、基站设备向终端设备发送多播业务数据。
其中,在基站设备向终端设备发送了第三控制信息之后,可以向终端设备发送多播业务数据。
进一步的,为了能够提高终端设备接收多播业务数据的成功率,基站设备可以向终端设备重复发送多播业务数据,在一种可能的实现方式中,用于控制多播业务数据的重复传输的参数全部包含在第三控制信息中,即采用第三控制信息来控制多播业务数据的重复传输,此时,具体的,基站设备可以根据第三控制信息向终端设备发送多播业务数据。其中,第三控制信息中可以包括第一配置参数,以用来控制多播业务数据的重复传输,该第一配置参数可以包括以下至少一项:第一偏移量、第一重复次数、第一重复模式、MCS、TBS、第一频率信息。其中,第一偏移量用于指示多播业务数据的 起始时刻滞后于第三控制信息起始时刻或终止时刻的偏移量,起始时刻指的是起始子帧号或起始系统帧号,终止时刻指的是终止子帧号或终止系统帧号。
另外,需要说明的是,本发明实施例中对于第一配置参数中其他参数的具体描述与步骤403对第二配置参数的描述类似,本发明实施例在此不再详细赘述。另外,第一配置参数中具体包括的内容可以根据实际应用场景的需求进行选择,本发明实施例在此并不做具体限定。且,若用来控制多播业务数据的重复传输所需的参数不包括在第一配置参数中时,可以将用来控制多播业务数据的重复传输所需的参数预先配置在基站设备和终端设备中,也可以根据实际应用场景的需求采用其他的方式通知终端设备,本发明实施例在此并不做具体限制。
示例性的,第一配置参数包括第一偏移量、第一重复次数、第一重复模式、MCS、TBS和第一频率信息。此时基站设备根据第三控制信息向终端设备发送多播业务数据具体的可以为:基站设备可以先根据第一偏移量确定当前的系统帧是否为需发送多播业务数据的系统帧,若确定出当前的系统帧被是需发送多播业务数据的系统帧,则判断当前的系统帧的下一个系统帧是否为需发送多播业务数据的系统帧,若确定出当前的系统帧是需发送多播业务数据的系统帧,则基站设备根据第三控制信息起始时刻或终止时刻、第一偏移量、第一重复次数和第一重复模式确定出需要在当前的系统帧或当前的调度周期的哪些子帧和/或符号上发送多播业务数据,然后根据确定出的所有子帧号和/或符号,以及MCS、TBS、和第一频率信息通过SC-MTCH向终端设备发送多播业务数据,以便实现多播业务数据的重复发送。
在另一种可能的实现方式中,为了减少终端设备获取到多播业务数据的时延,基站设备可以将用于控制多播业务数据的重复传输的参数全部包含在第一控制信息中,采用第一控制信息来控制多播业务数据的重复传输,也就是说,步骤409和步骤410此时可以不 用执行,此时,具体的,基站设备可以根据第一控制信息向终端设备发送多播业务数据。其中,第一控制信息中可以包括第一配置参数,以用来控制多播业务数据的重复传输,且该第一配置参数可以包括以下至少一项:第一偏移量、第一调度周期、第一起始时刻、第一终止时刻、第一重复次数、第一重复模式、MCS、TBS、session ID、TMGI、第一频率信息,第一终止时刻,指重复发送多播业务数据的最后一个帧位置和/或最后一个子帧位置和/或一个子帧中的最后一个符号位置,且第一配置参数与步骤403中第二配置参数的具体描述类似,本发明实施例在此不再详细赘述,并且,基站设备根据第一控制信息向终端设备发送多播业务数据的具体过程也与基站设备根据第三控制信息向终端设备发送多播业务数据的过程类似,本发明实施例在此也不再详细赘述。
在又一种可能的实现方式中,可以将部分用于控制多播业务数据的重复传输的参数包含在第一控制信息中,并且剩余部分用于控制多播业务数据的重复传输的参数包含在第三控制信息中,即采用第一控制信息和第三控制信息共同来控制多播业务数据的重复传输,此时,具体的,基站设备可以根据第一控制信息和第三控制信息向终端设备发送多播业务数据。其中,对于这种可能实现方式中,用于控制多播业务数据的重复传输的参数中哪些参数包含在第一控制信息中,哪些参数包含在第三控制信息中,可以根据实际应用场景的需求进行设置,本发明实施例在此不做限定。另外,第一控制信息和第三控制信息中包括的用来控制多播业务数据的重复传输的参数,与本步骤中第二种可能实现方式中的第一配置参数的具体描述类似,本发明实施例在此不再详细赘述,且,基站设备根据第一控制信息和第三控制信息向终端设备发送多播业务数据的具体过程也与基站设备根据第三控制信息向终端设备发送多播业务数据的过程类似,本发明实施例在此也不再详细赘述。
412、终端设备接收基站设备发送的多播业务数据。
其中,在基站设备向终端设备发送了多播业务数据之后,终端 设备便可以接收基站设备发送的多播业务数据。
进一步的,在一种可能的实现方式中,当基站设备根据第三控制信息向终端设备重复发送多播业务数据时,终端设备可以根据第三控制信息接收基站设备重复发送的多播业务数据,具体的,终端设备可以根据第三控制信息中包括的第一配置参数接收基站设备重复发送的多播业务数据。其中,对于第一配置参数的具体描述与步骤411中对第一配置参数的具体描述类似,本发明实施例在此不再详细赘述。
示例性的,按照步骤411中的例子,终端设备根据第三控制信息接收基站设备发送的多播业务数据具体的可以为:终端设备可以先根据第一偏移量确定当前的系统帧是否为需接收多播业务数据的系统帧,若确定出当前的系统帧不是需接收多播业务数据的系统帧,则判断当前的系统帧的下一个系统帧是否为需接收多播业务数据的系统帧,若确定出当前的系统帧是需接收多播业务数据的系统帧,则终端设备根据第三控制信息起始时刻或终止时刻、第一偏移量、第一重复次数和第一重复模式确定出需要在当前的系统帧或当前的调度周期的哪些子帧和/或符号上接收多播业务数据,然后根据确定出的所有子帧号和/或符号,以及MCS、TBS、第一频率信息通过SC-MTCH接收基站设备发送多播业务数据,由于可以在多个子帧号和/或符号上重复接收多播业务数据,因此提高了终端设备接收多播业务数据的成功率。
在另一种可能的实现方式中,当基站设备根据第一控制信息向终端设备发送多播业务数据时,终端设备可以根据第一控制信息接收多播业务数据,具体的,终端设备可以根据第一控制信息中包括的第一配置参数接收基站设备重复发送的多播业务数据。其中,对于第一配置参数的具体描述与步骤411中对第一配置参数的具体描述类似,本发明实施例在此不再详细赘述,并且,基站设备根据第一控制信息接收基站设备发送多播业务数据的具体过程也与基站设备根据第三控制信息接收基站设备发送多播业务数据的过程类似, 本发明实施例在此也不再详细赘述。
在又一种可能的实现方式中,当基站设备根据第一控制信息和第三控制信息向终端设备重复发送多播业务数据时,基站设备可以根据第一控制信息和第三控制信息接收多播业务数据,具体的,终端设备可以根据第一控制信息和第三控制信息中包括的第一配置参数接收基站设备重复发送的多播业务数据。其中,对于第一配置参数的具体描述与步骤411中对第一配置参数的具体描述类似,本发明实施例在此不再详细赘述,并且,基站设备根据第一控制信息和第三控制信息接收基站设备发送多播业务数据的具体过程也与基站设备根据第三控制信息接收基站设备发送多播业务数据的过程类似,本发明实施例在此也不再详细赘述。
本发明提供的数据传输方法,基站设备通过向终端设备发送用于控制多播业务数据的重复传输的第一控制信息,并通过根据第一控制信息向终端设备重复发送多播业务数据,使得终端设备可以根据接收到的第一控制信息接收基站设备重复发送的多播业务数据,以提高终端设备接收多播业务数据的成功率。这样,在引入SC-PTM技术的MTC中,MTC终端便可以通过根据接收到的第一控制信息接收基站重复发送的多播业务数据,从而提高了MTC终端接收数据的成功率。
并且,通过对第一控制信息、第二控制信息、第三控制信息、修改通知的重复传输,进一步的提高了MTC终端接收多播业务数据的成功率。且,通过将用于控制第一控制信息的重复传输的参数携带在系统消息中传输和/或将用于控制多播业务数据的重复传输的参数携带在第一控制信息中,减小了终端设备获取到多播业务数据的时延。另外,当第一控制信息发生改变时,通过在第二控制信息中携带用于指示第一控制信息发生改变的第一RNTI或者用第二控制信息指示所述第一控制信息发生改变,而非通过向终端设备发送修改通知,减小了终端设备获取到多播业务数据的时延。
