为便于理解本申请实施例的技术方案,以下对本申请实施例相关的技术方案进行说明。
随着人们对速率、延迟、高速移动性、能效的追求以及未来生活中业务的多样性、复杂性,为此第三代合作伙伴计划(3 rd Generation Partnership Project,3GPP)国际标准组织开始研发5G。5G的主要应用场景为:增强移动超宽带(enhanced Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable Low-Latency Communications,URLLC)、大规模机器类通信(massive Machine-Type Communications,mMTC)。
一方面,eMBB仍然以用户获得多媒体内容、服务和数据为目标,其需求增长十分迅速。另一方面,由于eMBB可能部署在不同的场景中,例如室内,市区,农村等,其能力和需求的差别也比较大,所以不能一概而论,必须结合具体的部署场景详细分析。URLLC的典型应用包括:工业自动化,电力自动化,远程医疗操作(手术),交通安全保障等。mMTC的典型特点包括:高连接密度,小数据量,时延不敏感业务,模块的低成本和长使用寿命等。
在NR早期部署时,完整的NR覆盖很难获取,所以典型的网络覆盖是广域的LTE覆盖和NR的孤岛覆盖模式。而且大量的LTE部署在6GHz以下,可用于5G的6GHz以下频谱很少。所以NR必须研究6GHz以上的频谱应用,而高频段覆盖有限、信号衰落快。同时为了保护移动运营商前期在LTE投资,提出了LTE和NR之间紧耦合(tight interworking)的工作模式。

RRC状态
5G为了降低空口信令和快速恢复无线连接,快速恢复数据业务的目的,定义了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC非激活(RRC_INACTIVE)状态。这种状态有别于RRC空闲(RRC_IDLE)状态和RRC激活(RRC_ACTIVE)状态。其中,
1)RRC_IDLE状态(简称为空闲(idle)态):移动性为基于UE的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在UE上下文,不存在RRC连接。
2)RRC_CONNECTED状态(简称为连接(connected)态):存在RRC连接,基站侧和UE侧存在UE上下文。网络侧知道UE的位置是具体小区级别的。移动性是网络侧控制的移动性。UE和基站之间可以传输单播数据。
3)RRC_INACTIVE状态(简称为非激活(inactive)态):移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE上下文存在某个基站上,寻呼由RAN触发,基于RAN的寻呼区域由RAN管理,网络侧知道UE的位置是基于RAN的寻呼区域级别的。

多媒体广播多播服务(Multimedia Broadcast Multicast Service,MBMS)
MBMS是一种通过共享网络资源从一个数据源向多个终端设备传送数据的技术,该技术在提供多媒体业务的同时能有效地利用网络资源,实现较高速率(如256kbps)的多媒体业务的广播和组播。
由于MBMS频谱效率较低,不足以有效地承载和支撑手机电视类型业务的运营。因此在LTE中,3GPP明确提出增强对下行高速MBMS业务的支持能力,并确定了对物理层和空中接口的设计要求。
3GPP R9将演进的MBMS(evolved MBMS,eMBMS)引入到LTE中。eMBMS提出了单频率网络(Single Frequency Network,SFN)的概念,即多媒体广播多播服务单频率网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN),MBSFN采用统一频率在所有小区同时发送业务数据,但是要保证小区间的同步。这种方式可以极大的提高小区整体信噪比分布,频谱效率也会相应的大幅提高。eMBMS基于IP多播协议实现业务的广播和多播。
在LTE或增强的LTE(LTE-Advanced,LTE-A)中,MBMS只有广播承载模式,没有多播承载模式。此外,MBMS业务的接收适用于空闲态或者连接态的终端设备。
3GPP R13中引入了单小区点对多点(Single Cell Point To Multiploint,SC-PTM)概念,SC-PTM 基于MBMS网络架构。
MBMS引入了新的逻辑信道,包括单小区多播控制信道(Single Cell-Multicast Control Channel,SC-MCCH)和单小区多播传输信道(Single Cell-Multicast Transport Channel,SC-MTCH)。SC-MCCH和SC-MTCH被映射到下行共享信道(Downlink-Shared Channel,DL-SCH)上,进一步,DL-SCH被映射到物理下行共享信道(Physical Downlink Shared Channel,PDSCH)上,其中,SC-MCCH和SC-MTCH属于逻辑信道,DL-SCH属于传输信道,PDSCH属于物理信道。SC-MCCH和SC-MTCH不支持混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)操作。
MBMS引入了新的系统信息块(System Information Block,SIB)类型,即SIB20。具体地,通过SIB20来传输SC-MCCH的配置信息,一个小区只有一个SC-MCCH。SC-MCCH的配置信息包括:SC-MCCH的修改周期、SC-MCCH的重复周期、以及调度SC-MCCH的无线帧和子帧等信息。进一步,1)SC-MCCH的修改周期的边界满足SFN mod m=0,其中,SFN代表边界的系统帧号,m是SIB20中配置的SC-MCCH的修改周期(即sc-mcch-ModificationPeriod)。2)调度SC-MCCH的无线帧满足:SFN mod mcch-RepetitionPeriod=mcch-Offset,其中,SFN代表无线帧的系统帧号,mcch-RepetitionPeriod代表SC-MCCH的重复周期,mcch-Offset代表SC-MCCH的偏移量。3)调度SC-MCCH的子帧通过sc-mcch-Subframe指示。
SC-MCCH通过物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度。一方面,引入新的无线网络临时标识(Radio Network Tempory Identity,RNTI),即单小区RNTI(Single Cell RNTI,SC-RNTI)来识别用于调度SC-MCCH的PDCCH(如SC-MCCH PDCCH),可选地,SC-RNTI固定取值为FFFC。另一方面,引入新的RNTI,即单小区通知RNTI(Single Cell Notification RNTI,SC-N-RNTI)来识别用于指示SC-MCCH的变更通知的PDCCH(如通知PDCCH),可选地,SC-N-RNTI固定取值为FFFB;进一步,可以用DCI 1C的8个比特(bit)中的一个bit来指示变更通知。在LTE中,SC-PTM的配置信息基于SIB20配置的SC-MCCH,然后SC-MCCH配置SC-MTCH,SC-MTCH用于传输业务数据。
具体地,SC-MCCH只传输一个消息(即SCPTMConfiguration),该消息用于配置SC-PTM的配置信息。SC-PTM的配置信息包括:临时移动组标识(Temporary Mobile Group Identity,TMGI)、会话标识(seession id)、组RNTI(Group RNTI,G-RNTI)、非连续接收(Discontinuous Reception,DRX)配置信息以及邻区的SC-PTM业务信息等。需要说明的是,R13中的SC-PTM不支持健壮性包头压缩(Robust Header Compression,ROHC)功能。
SC-PTM的下行非连续的接收是通过以下参数控制的:onDurationTimerSCPTM、drx-InactivityTimerSCPTM、SC-MTCH-SchedulingCycle、以及SC-MTCH-SchedulingOffset。
当满足[(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset时,启动定时器onDurationTimerSCPTM;
当接收到下行PDCCH调度时,启动定时器drx-InactivityTimerSCPTM;
只有当定时器onDurationTimerSCPTM或drx-InactivityTimerSCPTM运行时才接收下行SC-PTM业务。
SC-PTM业务连续性采用基于SIB15的MBMS业务连续性概念,即“SIB15+MBMSInterestIndication”方式。空闲态的终端设备的业务连续性基于频率优先级的概念。
根据上述描述可知,SC-PTM的配置是基于SIB20配置SC-MCCH,然后基于SC-MCCH配置SC-MTCH。一个小区有且仅有一个SC-MCCH,也就是说,在终端设备进行小区重选后需要重新获取SC-MCCH,这将会导致业务中断。
在新无线(New Radio,NR)系统中,很多场景需要支持组播和广播的业务需求,例如车联网中,工业互联网中等。所以在NR中引入MBMS是有必要的。
需要说明的是,上述方案中的MBMS业务包括但不局限于多播业务、组播业务、MBS业务等。本申请实施例以MBS业务为例进行说明,“MBS业务”的描述也可以被替换为“多播业务”或者“组播业务”或者“广播业务”或者“MBMS业务”。
NR支持广播类型的MBS业务,通过BCCH配置MCCH,通过MCCT配置MTCH。其中,MCCH用于传输MBS业务的配置信息,而MTCH用于传输MBS业务数据。一个小区有且仅有一个MCCH,MCCH中承载有信令(以下称为MCCH信令),通过MCCH信令配置多个MBS业务的配置信息。如果多个MBS业务的配置信息中一旦有一个MBS业务的配置信息发生变更,那么MCCH信令就会变更,这种情况下,网络侧会通知小区的所有用户更新MCCH信令,然而,有些用户是不需要更新MBS业务的配置信息的,这就导致这些用户受到影响,不利于这些用户的节能目的。为此,提出了 本申请实施例的以下技术方案。
本申请实施例的技术方案中,定义一个新的SIB(称为第一SIB),第一SIB也可以是SIB20,参照图2,第一SIB包括第一MCCH的配置信息,这里,第一MCCH为MBS业务的控制信道,换句话说,第一SIB用于配置NR MBS的控制信道的配置信息,可选地,NR MBS的控制信道也可以叫做NR MCCH(即所述第一MCCH)。
进一步,第一MCCH用于承载第一信令,本申请实施例对第一信令的名称不做限定,如第一信令为信令MCCH信令,所述第一信令包括至少一个第一MTCH的配置信息,这里,第一MTCH为MBS业务的业务信道(也称为数据信道或传输信道),第一MTCH用于传输MBS业务数据(如NR MBS的业务数据)。换句话说,第一MCCH用于配置NR MBS的业务信道的配置信息,可选地,NR MBS的业务信道也可以叫做NR MTCH(即所述第一MTCH)。
具体地,所述第一信令用于配置NR MBS的业务信道、该业务信道对应的业务信息以及该业务信道对应的调度信息。进一步,可选地,所述业务信道对应的业务信息,例如TMGI、session id等标识业务的标识信息。所述业务信道对应的调度信息,例如业务信道对应的MBS业务数据被调度时使用的RNTI,例如G-RNTI、DRX配置信息等。
需要说明的是,第一MCCH和第一MTCH的传输都是基于PDCCH调度的。
需要说明的是,本申请实施例对所述第一SIB、所述第一MCCH和所述第一MTCH的命名不做限制。为便于描述,所述第一SIB也可以简称为SIB,所述第一MCCH也可以简称为MCCH,所述第一MTCH也可以简称为MTCH,参照图3,通过SIB配置用于调度MCCH的PDCCH(即MCCH PDCCH)以及通知PDCCH(Notification PDCCH),其中,通过MCCH PDCCH携带的DCI调度用于传输MCCH的PDSCH(即MCCH PDSCH)。进一步,通过MCCH配置N个用于调度MTCH的PDCCH(即MTCH 1PDCCH、MTCH 2PDCCH、…、MTCH N PDCCH),其中,MTCH n PDCCH携带的DCI调度用于传输MTCH n的PDSCH(即MTCH n PDSCH),n为大于等于1且小于等于N的整数。MCCH和MTCH被映射到DL-SCH上,进一步,DL-SCH被映射到PDSCH上,其中,MCCH和MTCH属于逻辑信道,DL-SCH属于传输信道,PDSCH属于物理信道。

本申请实施例中,所述第一DCI用于指示至少一个MBS业务的配置信息发生变更。进一步,可选地,所述第一DCI还用于指示至少一个MBS业务启动、或者停止、或者暂停。以下对所述第一DCI如何进行指示进行说明。
●通过第一DCI中携带的第一指示信息指示至少一个MBS业务的配置信息发生变更。
本申请实施例中,所述第一DCI中携带第一指示信息,所述第一指示信息用于指示至少一个MBS业务的配置信息发生变更。这里,所述第一指示信息的实现可以有如下方式。
方式一:所述第一指示信息为MBS业务标识列表,所述MBS业务标识列表包括至少一个MBS业务标识,所述至少一个MBS业务标识中的每个MBS业务标识关联一个MBS业务;所述MBS业务标识列表用于指示所述至少一个MBS业务标识关联的至少一个MBS业务的配置信息发生变更。
进一步,可选地,所述MBS业务标识列表还用于指示以下之一:
所述至少一个MBS业务标识关联的至少一个MBS业务启动;
所述至少一个MBS业务标识关联的至少一个MBS业务停止;
所述至少一个MBS业务标识关联的至少一个MBS业务暂停。
在一个示例中,MBS业务标识列表为TMGI列表,TMGI列表包括至少一个TMGI,其中,TMGI列表中的每个TMGI关联一个MBS业务,通过TMGI列表指示至少一个MBS业务的配置信息发生变更。
例如:TMGI列表包括TMGI 1、TMGI 2和TMGI 3,其中,TMGI 1关联MBS业务1,TMGI 2关联MBS业务2,TMGI 3关联MBS业务3,该TMGI列表指示MBS业务1、MBS业务2和MBS业务3的配置信息发生变更。
方式二:所述第一指示信息为第一比特图,所述第一比特图中的每个比特位对应一个MBS业务标识,所述比特位的取值用于指示该比特位对应的MBS业务标识所关联的MBS业务的配置信息是否发生变更。
进一步,可选地,所述比特位的取值还用于指示以下之一:
该比特位对应的MBS业务标识所关联的MBS业务启动;
该比特位对应的MBS业务标识所关联的MBS业务停止;
该比特位对应的MBS业务标识所关联的MBS业务暂停。
本申请实施例中,所述第一比特图中的比特位与MBS业务标识之间的对应关系,可以通过以下方式确定:
方式a)所述第一比特图中的比特位与MBS业务标识之间的对应关系通过系统广播消息配置;或者,
方式b)所述第一比特图中的比特位按照从低位到高位的顺序,与第一配置中配置的MBS业务标识按照MBS业务标识从小到大的顺序一一对应;或者,
方式c)所述第一比特图中的比特位按照从低位到高位的顺序,与第一配置中配置的MBS业务标识按照MBS业务标识从大到小的顺序一一对应;
方式d)所述第一比特图中的比特位按照从低位到高位的顺序,与第一配置中配置的MBS业务标识按照配置顺序一一对应。
上述方案中,所述第一配置包括N个MBS业务的配置信息,N为正整数;其中,所述第一配置携带第一MCCH中的第一信令中,或者,所述第一配置携带在系统广播消息中。
在一个示例中,MBS业务标识为TMGI,第一比特图包括N个比特位,N个比特位中的每个比特位对应一个TMGI,比特位的取值用于指示该比特位对应的TMGI所关联的MBS业务的配置信息是否发生变更。
这里,N的取值基于第一配置中包含的MBS业务的配置信息的数量确定,可选地,N的取值等于第一配置中包含的MBS业务的配置信息的数量。通过所述第一比特图可以确定N个MBS业务的配置信息中的每个MBS业务的配置信息是否发生变更。
例如:N的取值为6,第一比特图为100101,其中,第一比特图按照从低位到高位的顺序与TMGI1、TMGI 2、TMGI 3、TMGI 4、TMGI 5、TMGI 6一一对应,比特位的取值为1表示该比特位对应的TMGI所关联的MBS业务的配置信息发生变更,比特位的取值为0表示该比特位对应的TMGI所关联的MBS业务的配置信息未发生变更,基于此,TMGI 1关联的MBS业务1、TMGI 3关联的MBS业务3、以及TMGI 6关联的MBS业务6的配置信息发生变更,而TMGI 2关联的MBS业务2、TMGI 4关联的MBS业务4、以及TMGI 5关联的MBS业务5的配置信息未发生变更。
本申请实施例中,所述终端设备根据所述第一DCI中携带的第一指示信息,确定是否更新所述终端设备相关的MBS业务的配置信息。进一步,可选地,所述终端设备根据所述第一DCI中携带的第一指示信息,确定是否开始接收所述终端设备相关的MBS业务、或者是否停止接收所述终端设备相关的MBS业务、或者是否暂停接收所述终端设备相关的MBS业务。
这里,所述终端设备相关的MBS业务可以是所述终端设备正在接收的MBS业务或者期望接收的MBS业务或者即将接收的MBS业务或者感兴趣的MBS业务。
在一个示例中,假设所述终端设备相关的MBS业务为MBS业务1,若所述终端设备根据所述第一DCI中携带的第一指示信息确定MBS业务1的配置信息发生了更新,则所述终端设备更新MBS业务1的配置信息;所述终端设备根据所述第一DCI中携带的第一指示信息确定MBS业务1的配置信息未发生更新,则所述终端设备不更新MBS业务1的配置信息。
●通过第一DCI的加扰信息指示至少一个MBS业务的配置信息发生变更。
本申请实施例中,所述第一DCI通过第一N-RNTI加扰,所述第一N-RNTI加扰的第一DCI用于指示至少一个MBS业务的配置信息发生变更。

在一可选方式中,网络设备可以通过系统广播消息配置多个第一N-RNTI,其中,每个第一N-RNTI都可以关联至少一个MBS业务标识。所述第一N-RNTI加扰的第一DCI用于指示该第一RNTI关联的至少一个MBS业务标识所关联的至少一个MBS业务的配置信息发生变更。
在一个示例中,MBS业务标识为TMGI。
本申请实施例中,所述终端设备根据加扰所述第一DCI的第一N-RNTI,确定是否更新所述终端设备相关的MBS业务的配置信息。进一步,所述终端设备根据加扰所述第一DCI的第一N-RNTI,确定是否开始接收所述终端设备相关的MBS业务、或者是否停止接收所述终端设备相关的MBS业务、或者是否暂停接收所述终端设备相关的MBS业务。
这里,所述终端设备相关的MBS业务可以是所述终端设备正在接收的MBS业务或者期望接收的MBS业务或者即将接收的MBS业务或者感兴趣的MBS业务。
在一个示例中,以MBS业务标识为TMGI为例,网络设备可以通过系统广播消息配置3个第一N-RNTI,分别为MBS N-RNTI 1,MBS N-RNTI 2和MBS N-RNTI 3,其中,MBS N-RNTI 1关联TMGI 1和TMGI 2,MBS N-RNTI 2关联TMGI 3,MBS N-RNTI 3关联TMGI 4和TMGI 4。终端设备接收到通过MBS N-RNTI 1加扰的第一DCI,通过MBS N-RNTI 1关联的TMGI 1和TMGI 2,可以确定TMGI 1关联的MBS业务1和TMGI 2关联的MBS业务2的配置信息发生了变更;假设所述终端设备相关的MBS业务为MBS业务1,终端设备确定出MBS业务1的配置信息发生了变更,所述终端设备更新MBS业务1的配置信息。
本申请实施例的技术方案,网络设备可以通过不同的第一N-RNTI加扰的第一DCI,来通知终端设备发生配置变更的至少一个TMGI,从而使得终端设备可以据此判决是否更新与自己相关的MBS业务的配置信息。
本申请实施例的技术方案还可以预先配置MBS业务的传输状态,来触发终端设备提前获取MSB业务的配置,降低MBS业务的丢失概率。
具体地,所述网络设备发送第一MCCH或者系统广播消息,所述第一MCCH或者系统广播消息携带第一配置,所述终端设备从第一MCCH或者系统广播消息中获取第一配置,所述第一配置包括N个MBS业务的配置信息,N为正整数。所述N个MBS业务的配置信息中的每个MBS业务的配置信息包含第二指示信息,所述第二指示信息用于指示所述MBS业务的传输状态。这里,所述MBS业务的传输状态为传输、或者未传输、或者即将传输、或者已经停止传输、或者暂停传输。
上述方案中,所述N个MBS业务的配置信息中的每个MBS业务的配置信息关联一个MBS业务的MBS业务标识。在一个示例中,所述MBS业务标识为TMGI。
在一可选方式中,所述N个MBS业务的配置信息中的每个MBS业务的配置信息还包含一个RNTI,所述RNTI用于加扰激活或者去激活所述MBS业务的DCI。这里,可选地,所述DCI还用于指示所述MBS业务的传输状态。终端设备可以使用所述RNTI监听PDCCH,从PDCCH中获取DCI,所述DCI用于指示MBS业务的传输状态。这里,所述MBS业务的传输状态为传输、或者未传输、或者即将传输、或者已经停止传输、或者暂停传输。
可选地,所述RNTI与一个小区关联或者与一个MBS业务标识关联或者与一组MBS业务标识关联。即所述RNTI可以是per cell或者per TMGI或者per TMGI group配置的。
