在SC-PTM机制中,当基站通过SC-PTM机制向终端设备发送MBMS时,在一个载波上通过MBMS点到多点控制信道(MBMS point-to-multipoint Control Channel,MCCH)向终端设备发送业务控制信息,业务控制信息通常包括:该MBMS的业务标识和与该MBMS对应的群组无线网络临时标识(Group-Radio Network Temporary Identity,G-RNTI)。G-RNTI用于指示需要接收该MBMS的终端设备。终端设备根据接收到的G-RNTI,在该同一载波上通过MBMS业务信道(MBMS traffic Channel,MTCH)接收该MBMS。
当一个终端设备位于多个小区的覆盖范围内时,一个小区对应一个载波频率,不同小区对应不同载波频率。该终端设备只能在一个小区对应的载波频率上接收MCCH和MTCH。

具体实施方式
下面将结合附图,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付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。
请参考图1A,其示出了本发明一示例性实施例提供的多播业务收发系统的结构示意图。该多播业务收发系统包括:网络设备120和终端设备140。
网络设备120是该系统中与终端设备140进行业务传输的网元。
可选的,网络设备120与终端设备140进行传输的业务是MBMS,网络设备120同时向多个终端设备发送一个MBMS,图1A中仅示例性的示出了一个终端设备140。在具体的实施例中,终端设备120通常是多个。
可选的,网络设备120是长期演进进阶(Long Term Evolution-Advance,LTE-A)系统中的至少一个演进型基站(evolutional Node B,eNB或e-NodeB)。
可选的,终端设备140是诸如手机、平板电脑、电子书阅读器和膝上型便携计算机等等具有无线网络通信能力的电子设备。
可选的,终端设备140同时位于网络设备120所提供的多个小区的覆盖范围内。图1A仅以终端设备140位于小区10和小区11的覆盖范围内进行举例说明。在具体的实施例中,终端设备140所位于的小区个数不予限定,可以是两个或者两个以上,本实施例对此不做限定。
可选的,网络设备120采用载波聚合技术与终端设备140进行业务传输。
网络设备与终端设备在传输MBMS时,网络设备向终端设备发送MCCH,发送MCCH是指发送承载在MCCH上的MBMS的业务控制信息。业务控制信息中包括该MBMS的临时多播组标识(Temporary Multicast Group Identifier,TMGI)和该MBMS对应的G-RNTI。G-RNTI用于指示需要接收该MBMS的至少一个终端设备,需要接收该MBMS的至少一个终端设备共用同一个G-RNTI。
如图1B所示,网络设备在每个重复周期(Repetition Period,RP)150向终端设备发送一次MCCH。一个修改周期(Modification Period,MP)161中包含多个重复周期150。在一个修改周期中,MCCH的内容不变化。当网络设备需要改变MCCH的内容时,在两个修改周期的边界处开始,在下一个修改周期中发送新的MCCH,如图1B所示,在修改周期161和修改周期162的边界处163开始,在修改周期162中发送新的MCCH,即修改周期161和修改周 期162中传输的MCCH的内容可以不同。
终端设备在一个修改周期中仅读取一次MCCH。在已经接入小区后,终端设备通常会读取一个修改周期中的第一次MCCH。当终端设备在一个修改周期中的中间时段才接入该小区时,则在接入小区后接收该修改周期中最近一次出现的MCCH。
终端设备在读取MCCH之后,根据MCCH上承载的MBMS的业务控制信息,接收MBMS的业务信道(MBMS Traffic Channel,MTCH),接收MTCH是指接收承载在MTCH信道上的MBMS数据。
载波聚合(Carrier Aggregation,CA)技术是指:将2个或2个以上成员载波(Component Carrier,CC)聚合在一起用于业务传输,以支持更大的带宽,每个成员载波的带宽可以达到20MHZ。网络设备和用户设备在采用载波聚合技术进行业务传输时,终端设备确定自己能够支持的成员载波的数量M,网络设备对该终端设备进行调度在M个成员载波上进行业务传输,不同的终端设备使用的成员载波的数量M可以是不同的,同一终端设备在传输不同业务时使用的成员载波的数量M也可以是不同的。

综上所述,本公开实施例提供的多播业务收发方法,通过网络设备在第一小区中向终端设备发送n个小区的配置信息和MBMS对应的MBMS对应的配置信息,n个小区的配置信息中包括:至少一个第二小区的配置信息,第二小区中包括至少一个用于和第一小区采用载波聚合技术共同传输MBMS的第二小区的小区标识,终端设备根据n个小区的配置信息和第二小区的小区标识确定第二小区的配置信息,根据第二小区的配置信息,从第二小区接收MTCH;解决了终端设备只能从一个小区中接收MBMS对应的MCCH和MTCH的问题;达到了终端设备可以通过载波聚合技术,从第一小区和至少一个第二小区中接收同一个多播业务的效果。
终端设备在从第二小区接收MTCH时,根据第二小区使用的是授权载波还是非授权载波的不同,有两种不同的接收方式。在本实施例中,以第二小区使用的是授权载波为例,对终端设备从第二小区接收MTCH的第一种方式进行说明。
请参考图5A,其示出了本发明一个示例性实施例提供的多播业务收发方法的流程图。本实施例以该方法应用于图1A所示的多播业务收发系统中进行说明,该方法包括:
步骤501,网络设备在第一小区中发送n个小区的配置信息,n个小区是支持协同传输MBMS的小区,配置信息至少包括小区标识、频率信息和带宽信息之间的对应关系。
可选的,网络设备通过系统广播信息或MCCH向终端设备发送n个小区的配置信息。
可选的,第一小区是主小区,第一小区使用授权载波。
可选的,配置信息包括:小区标识、频率信息、带宽信息、参考信号配置信息、信号门限中的至少一种,其中,频率信息、带宽信息、参考信号配置信息、信号门限是可选的。
可选的,n个小区中不同的小区的配置信息中包括的内容可以相同或不同。
可选的,n个小区的配置信息中,小区标识是物理小区标识或者是物理小区标识和小区编号,物理小区标识和小区编号对应。
可选的,物理小区标识可以是物理小区标识符(Physical Cell Identifier, PCI)、演进的通用移动通信系统(Universal Mobile Telecommunications System,UMTS)陆地接入网(Evolved UMTS Terrestrial Radio Access Network,E-UTRAN)小区全局标识符(E-UTRAN Cell Global Identifier,ECGI)或者其它用于标识小区的信息,本实施例对此不作限定。
可选的,小区的小区编号是该小区在n个小区的配置信息中的顺序编号,小区编号可以是显示配置的,即网络设备使用信令向终端设备指示小区的小区编号;小区编号也可以不用显式配置,即网络设备不使用信令进行指示,小区的小区编号和该小区在n个小区的配置信息中出现的顺序对应,本实施例对小区标识的类型不做限定。
可选的,n个小区中,不同的小区的小区标识所使用的标识类型可以相同或者不同。
如下表一所示,其示例性的示出了n个小区的配置信息的一种可能的形式:
  物理小区标识 频率信息/MHZ 带宽信息/MHZ 小区编号
小区1 物理小区标识1 800 5 1(00)
小区2 物理小区标识2 500 7 2(01)
小区3 物理小区标识3 300 3 3(10)
小区4 物理小区标识4 100   4(11)
表一
如上表一所示的n个小区的配置信息中包括小区1、小区2、小区3和小区4的配置信息,配置信息中包括的小区标识是物理小区标识和小区编号,小区1、小区2和小区3的配置信息中包括:物理小区标识、小区的频率信息、小区的带宽信息和小区编号,小区4的配置信息中包括:物理小区标识、频率信息和小区编号,与小区1、小区2和小区3的配置信息包括的内容不同。
在上表一中,小区编号是显式配置的,小区1的小区编号是1,小区2的小区编号是2,小区3的小区编号是3,小区4的小区编号是4,网络设备通过二进制方式表示小区编号,如上表一包括4个小区,则需要使用2比特信息表示,如上表一示出的使用00表示小区编号1、使用01表示小区编号2等;在另一个可能的实施例中,小区编号也可以不在n个小区的配置信息中显示配置,表一中不包括小区编号这一信息,则根据各小区在n个小区的配置信息中出现 的顺序,仍然可以得到小区1的小区编号是1,小区2的小区编号是2,小区3的小区编号是3,小区4的小区编号是4。
需要说明的是,上表一示出的n个小区的配置信息的内容和形式都是示例性的,上表一示出的不同小区的配置信息中包括的内容也是示例性的,本实施例对此不做限定。
步骤502,网络设备在第一小区中发送MBMS对应的配置信息,MBMS对应的配置信息中包括:至少一个第二小区的小区标识,第二小区用于和第一小区在同一调度时刻或不同调度时刻协同传输MBMS。
可选的,网络设备通过MCCH向终端设备发送MBMS对应的配置信息,MCCH可以是一个修改周期的第一个MCCH或者是一个修改周期中的最后一个MCCH。
可选的,MBMS对应的配置信息包括:至少一个第二小区的小区标识、MBMS的TMGI、第一G-RNTI和DRX参数中的至少一种,其中,TMGI和DRX参数是可选的,第一G-RNTI与MBMS对应。
可选的,第二小区是网络设备发送给终端设备的n个小区的配置信息中的n个小区的子集。
可选的,在MBMS对应的配置信息中,第二小区的小区标识是第二小区的小区编号和小区索引,小区索引用于在跨载波调度时在DCI中对第二小区进行标识,小区编号和小区索引对应。
其中,第二小区的小区编号是第二小区在n个小区的配置信息中的顺序编号,小区编号包含较多的数据信息,第二小区的小区索引是第二小区在MBMS对应的配置信息中的顺序编号,小区索引相比于小区编号,使用更少的数据信息对第二小区进行标识。
比如,当网络设备发送给终端设备的n个小区的配置信息中的小区编号显示配置时,网络设备通过发送信令指示小区的小区编号,当n个小区的配置信息中包括8个小区的配置信息时,网络设备在使用二进制表示小区编号时需要3比特信息,比如使用000表示小区编号1、001表示小区编号2……111表示小区编号8,假设MBMS对应的配置信息中包括一个第二小区的小区标识,该第二小区是n个小区中小区编号为3的小区,则该第二小区在MBMS对应的配置信息中的小区标识包括小区编号3和小区索引1,网络设备在指示该第二小区的小区编号时,仍然需要使用010表示小区编号3,即需要使用3比特信 息,而在指示该第二小区的小区索引时,只需要使用0表示小区索引1,即仅需要使用1比特信息。
需要说明的是,MBMS对应的配置信息中的第二小区的小区编号与该第二小区在n个小区的配置信息中的小区编号相同,第二小区的小区编号是不变的,但是第二小区在传输不同的MBMS时,对应的小区索引可以是不同的。
可选的,MBMS对应的配置信息中包括的至少一个第二小区,是用于和第一小区采用载波聚合技术在同一调度时刻或不同调度时刻协同传输MBMS的辅小区,是上述n个小区的配置信息中包含的n个小区的子集。
如下表二所示,其示例性的示出了MBMS对应的配置信息的一种可能的形式:
  小区编号 DRX参数 小区索引
小区2 2(01) 参数1 1(0)
小区4 4(11) 参数2 2(1)
表二
如上表二所示的MBMS对应的配置信息中包括两个第二小区,即上述表一中的小区2和小区4,MBMS对应的配置信息中包括小区2和小区4对应的小区编号、DRX参数和小区索引,小区2的小区编号为2、小区4的小区编号为4,与上述表一所示的n个小区的配置信息中小区2和小区4的小区编号相同,网络设备使用2比特信息进行指示,小区2的小区索引是小区2在表二所示的MBMS对应的配置信息中的顺序编号,小区2的小区索引是1,小区4的小区索引是小区4在表二所示的MBMS对应的配置信息中的顺序编号,小区4的小区索引是2,网络设备使用二进制信息对小区索引进行指示,如上表二包括两个第二小区,则网络设备使用1比特信息表示,如上表二所示,使用0标识小区索引1,使用1表示小区索引2。
需要说明的是,上述表二示出的内容和形式都是示例性的,本实施例对此不作限定。
在本实施例中,以MBMS对应的配置信息中的第二小区使用授权载波为例。
需要说明的是,上述n个小区的配置信息可以是多个MBMS共用的配置 信息,在传输不同的MBMS时,和第一小区采用载波聚合技术在同一调度时刻或不同调度时刻协同传输MBMS的第二小区可以是不同的,比如,网络设备向终端设备发送的n个小区的配置信息如上表一所示,网络设备和终端设备在传输一个MBMS时,使用小区1作为第二小区;在传输另一个MBMS时,使用小区2作为第二小区。
终端设备从第一小区中接收n个小区的配置信息,从第一小区中接收MBMS对应的配置信息的方法与上述步骤501和步骤502相同,本实施例对此不再赘述。
步骤503,终端设备根据第二小区的小区标识,从n个小区的配置信息中获取第二小区的配置信息。
终端设备在n个小区的配置信息中,查找与MBMS对应的配置信息中包括的第二小区的小区标识所对应的配置信息,第二小区的配置信息包括的内容与上述n个小区的配置信息包括的内容类似,本实施例对此不再赘述。
在一个示例性的例子中,第二小区的小区标识是小区编号,终端设备接收到的MBMS对应的配置信息中的第二小区的小区编号是小区编号2和小区编号4,终端设备接收到的n个小区的配置信息如上表一所示,则终端设备根据小区编号2和小区编号4,从n个小区的配置信息中获取2个第二小区的配置信息,即小区编号为2和小区编号为4的配置信息。
步骤504,终端设备通过第一G-RNTI从第一小区接收调度信息,并根据调度信息从第一小区接收MTCH。
其中,调度信息用于指示MTCH所占用的时频资源位置。
需要说明的是,终端设备也可以通过第一G-RNTI从第二小区接收调度信息,通过跨载波调度的方式根据调度信息从第一小区接收MTCH。
可选的,终端设备在接收到的MBMS对应的配置信息所在子帧的N个子帧之后,N为大于等于0的数值,根据第二小区的配置信息,从第二小区接收MTCH,终端设备使用下列步骤505或者步骤506所示的方法从第二小区接收MTCH。
步骤505,终端设备根据第二小区的配置信息,通过第一G-RNTI从第二小区接收调度信息,并根据调度信息从第二小区接收MTCH。
步骤506,终端设备根据第二小区的配置信息,通过第一G-RNTI从第一小区接收调度信息,并根据调度信息从第二小区接收MTCH。
需要说明的是,步骤504和步骤505或,步骤504和步骤506没有特定的先后关系,视具体的调度策略执行。
对应的,网络设备在接收到的MBMS对应的配置信息所在子帧的N个子帧之后,根据第二小区的配置信息,在第二小区中发送MTCH,网络设备使用两种不同的方法在第二小区中发送MTCH:
网络设备通过第一G-RNTI在第一小区中发送MTCH,并根据第二小区的配置信息与上述步骤504所示的方法相同;
网络设备通过第一G-RNTI在第二小区发送调度信息,并根据调度信息在第二小区中发送MTCH的方法与上述步骤505类似,或者,网络设备根据第二小区的配置信息,通过第一G-RNTI在第一小区中发送调度信息,并根据调度信息在第二小区中发送MTCH的方法与上述步骤506类似,本实施例对此不再赘述。
综上所述,本公开实施例提供的多播业务收发方法,通过网络设备在第一小区中向终端设备发送MBMS对应的配置信息,MBMS对应的配置信息中包括:至少一个第二小区的小区标识,终端设备根据第二小区的小区标识获取第二小区的配置信息,第二小区用于与第一小区在同一调度时刻或不同调度时刻协同传输MBMS,终端设备根据第二小区的配置信息从第二小区接收MTCH;解决了终端设备只能从一个小区中接收MBMS对应的MCCH和MTCH的问题;达到了终端设备可以通过载波聚合技术,从第一小区和至少一个第二小区中接收同一个多播业务的效果
综上所述,本公开实施例提供的多播业务收发方法,网络设备只需要向终端设备指示第一G-RNTI,终端设备可以通过第一G-RNTI从第一小区和至少一个第二小区中接收MTCH,网络设备不需要再使用信令向终端设备指示每个第二小区使用的G-RNTI,从而节省了空口信令。
在基于图5A所示实施例的其他可选实施例中,如图5B所示,在本实施例中,以第二小区使用的是非授权载波为例,对终端设备从第二小区接收MCCH的第二种方式进行说明。
基于上述步骤501和步骤502示出的n个小区的配置信息和MBMS对应的配置信息,在本实施例中,在n个小区的配置信息或者MBMS对应的配置信息中,第二小区的配置信息还包括:第二G-RNTI。
则上述步骤505和步骤506可被替代实现为步骤507:
步骤507,终端设备根据第二小区的配置信息,通过第二G-RNTI从第二小区接收接收调度信息,并根据调度信息从第二小区接收MTCH。
可选的,终端设备在接收到MBMS对应的配置信息所在子帧的N个子帧之后,根据第二小区的配置信息,从第二小区接收MTCH。
需要说明的是,在本实施例中,第二小区使用的也可以是授权载波。
网络设备根据第二小区的配置信息,通过第二G-RNTI在第二小区中发送调度信息,并根据调度信息在第二小区中发送MTCH的方法与上述步骤507类似,本实施例对此不再赘述。
综上所述,本公开实施例提供的多播业务收发方法,和第一小区采用载波聚合技术共同传输MBMS的第二小区使用的可以是非授权载波,达到了终端设备可以从使用非授权频谱的第二小区中接收多播业务,提高了对非授权频谱资源的利用率。
在基于图5A所示的实施例中,当终端设备通过步骤506所示的跨载波调度的方式从第二小区接收MTCH的方法时,包括如下几个步骤,如图6所示:
步骤601,网络设备通过第一G-RNTI在第一小区中向终端设备发送DCI,DCI中的预定字段中携带有调度的第二小区的小区标识。
可选的,DCI中的预定字段携带的第二小区的小区标识是小区索引。
可选的,网络设备通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)向终端设备发送DCI。
在本实施例中,网络设备通过第一小区向终端设备发送的DCI中携带有第二小区的小区标识,由于传统的DCI format 1A不存在专用的字段用于传递第二小区的小区标识。所以,在本实施例中,对传统DCI format 1A中的预定字段进行重新定义,使用传统DCI format 1A中的有用字段或多余字段传递第二小区的小区标识,本实施例中的DCI可以被称为DCI format 1A,或者,被称为其它DCI format,比如DCI format 1M,本实施例对此不作限定。
可选的,在频分双工模式(Frequency Division Duplexing,FDD)中,传统DCI format 1A中包括至少9比特的多余字段;在时分双工模式(Time Division Duplexing,TDD)中,传统DCI format 1A中包括至少11比特的多余字段。
在本实施例中,由于终端设备在接收网络设备发送的多播业务后,不需要向网络设备反馈HARQ信息,所以与HARQ机制有关的HARQ process number、NDI、RV和TPC command for PUCCH都是多余字段;另外,多播业务是由网络设备发送给终端设备的,即工作在下行链路中,而DCI format 0是用于指示上行调度信息,所以Flag for format0/format1A differentiation也是多余字段。
在本实施例中,使用DCI format 1A中的多余字段作为预定字段传递第二小区的小区标识,也即,预定字段是:HARQ process number、NDI、RV、TPC command for PUCCH,以及Flag for format0/format1A differentiation中的至少一种。
在一个示例性的例子中,如下表三示例性的示出了传统DCI format 1A的一种可能的形式,其示出了不同的字段及其对应的字段长度:
DCI format 1A
Flag for format0/format1A differentiation–1bit
LVRB/DVRB assignment flag–1bit
RB assignment
MCS–5bits
NDI–1bit
RV–2bits
-
TPC command for PUCCH–2bits
HARQ process number–3bits
表三
其中,LVRB/DVRB assignment flag是指集中式虚拟资源块(Localized VirtualResourceBlock,LVRB)/分布式虚拟资源块(Distributed VirtualResourceBlock,DVRB)的资源分配标识,RB assignment是指资源块(Resource Block,RB)的资源分配方式,RB assignment对应的字段长度是不固定的,本实施例对此不作限定。
需要说明的是,上述表三示出的内容和形式都是示例性的,本实施例对此不作限定。在一个示例性的例子中,DCI中的预定字段是HARQ process number,即DCI是对传统DCI format 1A中的HARQ process number进行了重新定义,则网络设备使用HARQ process number对应的3比特用来传递小区标识。
步骤602,终端设备通过第一G-RNTI从第一小区接收DCI。
步骤603,终端设备对DCI中的预定字段进行解析,获取第二小区的小区标识。
可选的,终端设备根据DCI中的其他字段解析得到调度信息,比如,根据RB assignment确定在哪个资源块上从第二小区进行接收,本实施例对其他字段的内容不作限定。
终端设备对DCI中的预定字段解析得到的小区索引,根据小区索引确定小区索引对应的第二小区是被调度的第二小区。
步骤604,终端设备根据第二小区的小区标识,确定被调度的第二小区的配置信息。
可选的,终端设备接收到的DCI中的小区索引对应的第二小区是被调度的第二小区,是MBMS对应的配置信息中的至少一个第二小区。
可选的,终端设备根据解析得到的第二小区的小区索引和MBMS对应的配置信息确定被调度的第二小区的小区编号,根据被调度的第二小区的小区编号和n个小区的配置信息确定被调度的第二小区的配置信息。
在一个示例性的例子中,终端设备接收到的n个小区的配置信息如上表一所示,MBMS对应的配置信息如上表二所示,终端设备对接收到的DCI中的预定字段解析得到小区索引为1,则终端设备根据小区索引和MBMS对应的配置信息确定小区索引1对应的小区编号是2,并根据小区编号和n个小区的配置信息,确定小区编号为2的第二小区是小区2,则被调度的第二小区是小区2,并确定小区2的配置信息。
步骤605,网络设备根据第二小区的配置信息,在第二小区中发送MTCH。
步骤606,终端设备根据第二小区的配置信息,从第二小区接收MTCH。
终端设备根据确定的被调度的第二小区的配置信息,从该第二小区接收MTCH,在上述示例性的例子中,终端设备从小区2中接收MTCH。
在一个示例性的例子中,网络设备和终端设备在如图1A示出的系统中进行多播业务的传输,终端设备140在2个成员载波上接收进行传输的MBMS,主载波对应的是第一小区10,辅载波对应的是第二小区11,第一小区使用授权载波,第二小区使用非授权载波,则网络设备120和终端设备140在进行业务传输时的示意图如图7所示:
终端设备从第一小区中接收MCCH,MCCH上承载n个小区的配置信息和MBMS对应的配置信息,终端设备根据MCCH,从第一小区接收MTCH和/或从第二小区接收MTCH。
在基于上述实施例的其他可选实施例中,终端设备在从第一小区和/或第二小区接收MTCH之前,还包括以下步骤,如图8所示:
在本实施例中,第二小区的配置信息中还包括:信号门限和第二小区的参考信号配置信息;
步骤801,终端设备根据第二小区的参考信号配置信息获取第二小区的信号测量结果。
可选的,参考信号配置信息是发现参考信号(Discovery Reference Signal,DRS)和/或公共参考信号(Common Reference Signal,CRS)的配置信息。
步骤802,当第二小区的信号测量结果小于或等于信号门限时,终端设备向网络设备反馈第一指示信息。
第一指示信息用于向网络设备指示第二小区的信号测量结果小于或等于信号门限,表示该终端设备在第二小区的信号质量已经很差。
需要说明的是,本实施例对信号门限的取值不作限定。
步骤803,网络设备接收终端设备反馈的第一指示信息。
可选的,网络设备在接收到终端设备反馈的第一指示信息后,存在两种方式调度终端设备重新接收MBMS:确定新的第二小区;或者,放弃使用载波聚合技术传输该MBMS,本实施例对此不做限定,本实施例对第一指示信息中包括的内容也不作限定。
可选的,网络设备重新向终端设备发送MBMS对应的配置信息,重新发送的MBMS对应的配置信息中包括:新的第二小区的小区标识。
在一个示例性的例子中,n个小区的配置信息如上表一所示,用于和第一小区采用载波聚合技术共同传输MBMS的第二小区是小区2,当终端设备测量 到小区2的信号测量结果小于信号门限时,向网络设备反馈第一指示信息,网络设备在接收到第一指示信息后,确定新的第二小区为小区3,并重新向终端设备发送包含小区3的小区标识的MBMS对应的配置信息,由小区3和小区1共同MBMS。或者,网络设备向终端设备发送用于指示放弃使用载波聚合技术传输该MBMS的信令,由第一小区单独传输该MBMS。
综上所述,本公开实施例提供的多播业务收发方法,通过终端设备对第二小区的信号进行测量得到信号测量结果,当信号测量结果小于或等于信号门限时,向网络设备反馈第一指示信息,达到了当用于传输MTCH的第二小区的信号很差时,可以及时向网络设备进行反馈,避免因第二小区信号太差造成的传输错误的效果。
在基于上述实施例的其他可选实施例中,终端设备在从第一小区和/或第二小区接收MTCH之前,还包括以下步骤,如图9所示:
在本实施例中,第二小区的配置信息中还包括:信号门限和第二小区的参考信号配置信息;
步骤901,终端设备根据第二小区的参考信号配置信息获取第二小区的信号测量结果。
可选的,参考信号配置信息是DRS和/或CRS的配置信息。
步骤902,终端设备获取第一小区的信号测量结果。
步骤903,当第二小区的信号测量结果小于或等于信号门限,且第一小区的信号测量结果大于信号门限时,向网络设备反馈第二指示信息。
第二指示信息用于向网络设备指示第一小区的信号测量结果大于信号门限且第二小区的信号测量结果小于或等于信号门限。
需要说明的是,本实施例对信号门限的取值不作限定,对第二指示信息中包括的内容也不作限定。
可选的,当第一小区的信号测量结果小于或等于信号门限时,不向网络设备反馈第二指示信息。
步骤904,网络设备接收终端设备反馈的第二指示信息。
可选的,网络设备在接收到终端设备反馈的第二指示信息后,存在两种方式调度终端设备重新接收MBMS:确定新的用于和第一小区共同传输MBMS的第二小区;或者,放弃使用载波聚合技术传输该MBMS,本实施例对此不做 限定。
可选的,网络设备重新向终端设备发送MBMS对应的配置信息,重新发送的MBMS对应的配置信息中包括新的用于和第一小区共同传输MBMS的第二小区的小区标识。
综上所述,本公开实施例提供的多播业务收发方法,终端设备对第一小区和第二小区的信号进行测量得到信号测量结果,由于在第一小区的信号也较差的情况下,即使向网络设备反馈后仍然不能使用信号更好的小区进行多播业务的传输,所以当第二小区的信号较差时,同时对第一小区的信号进行检测,当第一小区信号较好、第二小区信号较差时,才向网络设备进行反馈,避免了无意义的反馈信息造成的空口信令的浪费。
