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。
需要说明的是,上述方案虽然是以MBMS业务为例进行说明的,但本申请实施例的技术方案不局限于此。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“MBMS业务”。
在NR系统中,很多场景需要支持组播类型和广播类型的业务需求,例如车联网中,工业互联网中等。所以在NR中引入组播类型和广播类型的MBS业务是有必要的。需要说明的是,组播类型的MBS业务是指通过组播方式传输的MBS业务。广播类型的MBS业务是指通过广播方式传输的MBS业务。
在NR系统中,对于组播类型的MBS业务来说,MBS业务是发给某个组中的所有终端设备。终端设备在RRC连接状态下接收组播类型的MBS业务,终端设备可以通过PTM方式或者PTP方式接收组播类型的MBS业务数据。其中,参照图2,PTM方式的MBS业务数据通过网络侧配置的G-RNTI来加扰对应的调度信息,PTP方式的MBS业务数据通过C-RNTI来加扰对应的调度信息。
对于组播类型的MBS业务来说,基站从共享隧道(tunnel)接收核心网下发的MBS业务后,可以将该MBS业务通过空口下发给一个组中的所有终端设备。这里,基站可以通过PTP方式和/或PTM方式将MBS业务下发给一个组中的所有终端设备。例如:一个组包括终端设备1、终端设备2和终端设备3,基站可以通过PTP方式将MBS业务下发给终端设备1,通过PTP方式将MBS业务下发给终端设备2,通过PTP方式将MBS业务下发给终端设备3;或者,基站可以通过PTP方式将MBS业务下发给终端设备1,通过PTM方式将MBS业务下发给终端设备2和终端设备3;或者,基站可以通过PTM方式将MBS业务下发给终端设备1,终端设备2以及终端设备3。参照图3,在核心网到基站之间采用一个共享的GTP隧道(Shared GTP tunnel)来传输MBS业务,即无论是PTM方式的MBS业务还是PTP方式的MBS业务都是共享这个GTP隧道的。基站按照PTM方式下发MBS业务数据给UE1和UE2,以及按照PTP方式下发MBS业务数据给UE3。
一般,终端设备通过PTM方式接收MBS业务,但当该终端设备的信号质量不好,或者小区内接收该MBS业务的用户很少的情况下,网络设备会判决通过PTP方式给终端设备发送MBS业务,相应地,终端设备通过PTP方式接收网络设备发送的MBS业务。同时,为了终端设备节能的目的,网络设备会通知终端设备去激活PTM方式,终端设备去激活PTM方式后,停止监听G-RNTI加扰的MBS业务的调度信息,进而停止接收PTM方式的MBS业务。网络设备如何通知终端设备关于MBS业务的传输方式是个需要解决的问题。为此,提出了本申请实施例的以下技术方案。
为便于理解本申请实施例的技术方案,以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合,其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。

以下结合具体应用实例对本申请实施例的技术方案进行举例说明。
应用实例一
基站通过RRC专用信令配置第一终端设备在MBS业务接收过程中的索引号为1,该索引号在基站覆盖的小区内的该MBS业务内是唯一的。基站判断切换某个或者某些终端设备部的传输方式切换到PTP方式。基站下发第一命令,所述第一命令包括MBS业务对应的MBS组内的所有终端设备的传输方式指示。
在一个示例中,所述第一命令携带第一比特图,所述第一比特图包括多个比特位,所述多个比特位按照从低位到高位的顺序,与MBS组内的多个终端设备按照索引从小到大的顺序一一对应。例如第一终端设备被分配的索引为3,则在第一比特图中从低位向高位数第三个比特位就是该第一终端设备对应的比特位,该比特位的取值表征第一终端设备对应的传输方式指示。如果比特位的取值为1则表示第一终端设备的传输方式为PTP方式,换句话说,比特位的取值为1则表示第一终端设备激活或者切换到PTP方式,并且去激活PTM方式。如果比特位的取值为0则表示第一终端设备的传输方式为PTM方式,换句话说,比特位的取值为0则表示第一终端设备激活或者切换到PTM方式,并且去激活PTP方式。上述比特位的取值也可以反过来。
第一比特图可以承载MAC CE中或者DCI中。
1)如果第一比特图承载在DCI中,则该DCI通过G-RNTI加扰,该G-RNTI可以是用于MBS业务调度的G-RNTI,或者,该G-RNTI可以是专用于传输方式指示的G-RNTI。
2)如果第一比特图承载在MAC CE中,则为该MAC CE定义一个LCID,通过该LCID来标识这个MAC CE。该MAC CE对应的调度信息通过G-RNTI加扰,该G-RNTI可以是用于MBS业务调度的G-RNTI,或者,该G-RNTI可以是专用于传输方式指示的G-RNTI。
在一可选方式中,G-RNTI可以是用于MBS业务调度的G-RNTI,或者,G-RNTI也可以是专用于传输方式指示的G-RNTI,如果每个G-RNTI对应一个MBS业务,即每个G-RNTI对应一个MBS会话标识,则MAC CE中不需要包含MBS会话标识。
作为示例,参照图7,MAC CE包括第一比特图,第一比特图包括16个比特位,分别与16个终端设备的索引对应,比特位的取值用于指示该比特位对应的终端设备的传输方式。此外,MAC CE还包括长度(Length)指示域,用于指示第一比特图包括的比特位数。
在一可选方式中,G-RNTI可以是用于MBS业务调度的G-RNTI,如果每个G-RNTI对应多个MBS业务,即每个G-RNTI对应多个MBS会话标识,则MAC CE中需要包含MBS会话标识,该MBS会话标识用于确定第一比特图应用的MBS业务。考虑到MBS会话标识太大,因此,通过RRC专用信令为第一终端设备配置关于共享一个G-RNTI的多个MBS业务中每个MBS业务分配的一个MBS索引(MBS index),MAC CE中包含MBS会话标识对应的MBS索引。
作为示例,参照图8,MAC CE包括第一比特图,第一比特图包括16个比特位,分别与16个终端设备的索引对应,比特位的取值用于指示该比特位对应的终端设备的传输方式。此外,MAC CE还包括长度(Length)指示域,用于指示第一比特图包括的比特位数。此外,MAC CE还包括MBS索引,用于指示第一比特图应用的MBS业务。

这里,DCI指示的传输方式可以通过RRC信令进行配置或者通过协议约定或者通过DCI中携带的指示位来确定。作为示例,DCI中携带1比特的指示位,该指示位的取值用于指示传输方式,例如指示位的取值为1表示PTP方式,指示位的取值为0表示PTM方式。指示位的取值反过来也可以。
在一可选方式中,G-RNTI可以是用于MBS业务调度的G-RNTI,若一个G-RNTI对应多个MBS业务,即一个G-RNTI对应多个MBS会话标识,则DCI中携带第二比特图,第二比特图包括多个比特位,多个比特位与多个MBS业务一一对应,比特位的取值用于指示该比特位对应的MBS业务对应的MBS组内的全体终端设备的传输方式,例如例如比特位的取值为1表示PTP方式,比特位的取值为0表示PTM方式。指示位的取值反过来也可以。这里,第二比特图中的多个比特位与多个MBS业务之间的对应关系可以通过协议预定或者通过RRC信令进行配置。
方案B)基站通过MAC CE通知一个或多个MBS业务对应的MBS组内的全体终端设备的传输方式,这里,传输方式可以是PTM方式或者PTM方式。该MAC CE对应的调度信息通过G-RNTI加扰。
在一可选方式中,G-RNTI可以是用于MBS业务调度的G-RNTI,或者,G-RNTI也可以是专用于传输方式指示的G-RNTI。若一个G-RNTI对应一个MBS业务,即一个G-RNTI对应一个MBS会话标识,则包含该MAC CE的LCID的子头用于指示该MBS业务对应的MBS组内的全体终端设备的传输方式为PTM方式或者PTP方式。
这里,MAC CE指示的传输方式可以通过RRC信令进行配置或者通过协议约定或者通过MAC CE中携带的指示位来确定。作为示例,MAC CE中携带1比特的指示位,该指示位的取值用于指示传输方式,例如指示位的取值为1表示PTP方式,指示位的取值为0表示PTM方式。指示位的取值反过来也可以。
在一可选方式中,G-RNTI可以是用于MBS业务调度的G-RNTI,若一个G-RNTI对应多个MBS业务,即一个G-RNTI对应多个MBS会话标识,则MAC CE中携带第二比特图,第二比特图包括多个比特位,多个比特位与多个MBS业务一一对应,比特位的取值用于指示该比特位对应的MBS业务对应的MBS组内的全体终端设备的传输方式,例如例如比特位的取值为1表示PTP方式,比特位的取值为0表示PTM方式。指示位的取值反过来也可以。这里,第二比特图中的多个比特位与多个MBS业务之间的对应关系可以通过协议预定或者通过RRC信令进行配置。
