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。
处于RRC空闲状态、RRC非激活状态、RRC连接状态的终端设备都能接收广播的MBS业务。为了保证RRC连接状态的终端设备接收广播的MBS业务的连续性,终端设备在RRC连接状态时需要指示网络侧终端设备感兴趣或者正在接收的MBS业务的标识信息,以便于网络侧在进行切换判决时优先考虑支持该MBS业务的小区作为切换的目标小区。
在NR中,不同于LTE,终端设备进入RRC连接状态后,网络侧给终端设备配置多个专用BWP(如最多4个专用BWP),终端设备在RRC连接状态下可以在这些专用BWP之间切换,例如基于DCI或者定时器等机制实现BWP之间的切换。终端设备在RRC空闲状态或者RRC非激活状态下接收广播的MBS业务,从RRC空闲状态或者RRC非激活状态进入RRC连接状态后,网络侧不明确终端设备之前接收的MBS业务,如果按照目前的方式为终端设备配置专用BWP,会导致终端设备无法正常接收MBS业务。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,终端设备上报其在RRC空闲状态或者RRC非激活状态下感兴趣或者正在接收的MBS业务的标识信息,便于网络侧配置合适的专用BWP,避免终端设备进行不必要的BWP切换,保障了MBS业务是正常接收。
图2是本申请实施例提供的MBS业务的指示方法的流程示意图一,如图2所示,所述MBS业务的指示方法包括以下步骤:
步骤201:终端设备向网络设备发送MBS业务的标识信息,网络设备接收终端设备发送的MBS业务的标识信息,所述MBS业务为所述终端设备期望的MBS业务或者正在接收的MBS业务;其中,所述MBS业务的标识信息用于所述终端设备的专用下行BWP的配置和/或所述MBS业务的标识信息用于确定所述终端设备待切换的目标小区。
本申请实施例中,所述MBS业务的标识信息用于所述网络设备为所述终端设备配置专用下行BWP和/或所述MBS业务的标识信息用于所述网络设备为所述终端设备选择待切换的目标小区。
本申请实施例中,终端设备在RRC空闲状态或者RRC非激活状态或者RRC连接状态下,都可以接收广播的MBS业务。终端设备在RRC空闲状态或者RRC非激活状态下接收广播的MBS业务的情况下,如果终端设备从RRC空闲状态或者RRC非激活状态进入RRC连接状态,则终端设备可以在进入RRC连接状态后或者进入RRC连接状态的过程中,向网络设备发送MBS业务的标识信息,这里的MBS业务是指终端设备在之前的RRC空闲状态或者RRC非激活状态下期望的MBS业务或者正在接收的MBS业务,从而网络设备可以根据终端设备指示的MBS业务的标识信息,为所述终端设备配置专用下行BWP和/或为所述终端设备选择待切换的目标小区。

需要说明的是,本申请上述方案中描述的“MBS业务的标识信息”可以是指一个MBS业务的标识信息也可以是指多个MBS业务的标识信息(即MBS标识信息列表)。
以下结合具体应用示例对本申请实施例的技术方案进行举例说明,需要说明的是,以下应用示例中以终端设备为UE为例,网络设备为gNB为例进行说明。
应用示例一
应用示例一对应于上述方案中的情况一,参照图3,图3是本申请实施例提供的MBS业务的指示方法的流程示意图二,如图3所示,所述MBS业务的指示方法包括以下步骤:
步骤301:UE处于RRC空闲状态,正在接收广播的MBS业务。
这里,所述广播的MBS业务的标识信息为TMGI-1。
步骤302:UE向gNB发送RRC建立请求(RRCSetupRequest)消息。
这里,UE通过SRB0向gNB发送RRC建立请求消息。
步骤303:gNB向UE发送RRC建立(RRCSetup)消息。
这里,gNB通过SRB1向UE发送RRC建立消息。
步骤304:UE进入RRC连接状态。
步骤305:UE向gNB上报UE感兴趣或者正在接收的MBS业务的标识信息。
这里,UE感兴趣或者正在接收的MBS业务的标识信息例如是TMGI-1。
需要说明的是,UE感兴趣或者正在接收的MBS业务的标识信息不限于一个TMGI,也可以是一个TMGI列表。

方式1-1:UE通过RRC建立完成(RRCSetupComplete)消息上报UE感兴趣或者正在接收的MBS业务的标识信息。这里,RRC建立完成消息(也即MSG5)通过SRB1传输。
方式1-2:UE通过一个新的RRC消息上报UE感兴趣或者正在接收的MBS业务的标识信息。这里,新的RRC消息例如是MBS兴趣指示(MBSInterestingIndication)消息。
需要说明的是,上述方式1-1和方式1-2没有进行安全考虑,即携带MBS业务的标识信息的RRC消息是未经过安全处理的,因而在没有安全问题的情况下可以使用上述方式1-1或方式1-2来上报MBS业务的标识信息。
方式2-1:UE通过安全激活完成(SecurityModeComplete)消息上报UE感兴趣或者正在接收的MBS业务的标识信息。
方式2-2:UE通过UE辅助信息(UEAssistanceInformation)消息上报UE感兴趣或者正在接收的MBS业务的标识信息。
方式2-3:UE通过一个新的RRC消息上报UE感兴趣或者正在接收的MBS业务的标识信息。这里,新的RRC消息例如是MBS兴趣指示(MBSInterestingIndication)消息。
需要说明的是,上述方式2-1、方式2-2和方式2-3进行了安全考虑,即携带MBS业务的标识信息的RRC消息是经过安全处理的(即在AS层安全激活之后才上报RRC消息),因而在没有或者有安全问题的情况下可以使用上述方式2-1或方式2-2或方式2-3来上报MBS业务的标识信息。
步骤306:gNB向UE发送RRC重配置(RRCReconfiguration)消息,携带专用下行BWP的配置信息。

进一步,如果UE在SCell上接收广播的MBS业务,则该SCell不能被去激活,不能配置dormant BWP(即该SCell不能处于具有休眠行为的激活状态)。或者,如果UE在SCell上接收广播的MBS业务,则如果SCell被去激活,或者配置dormant BWP并激活了dormant BWP,则UE仅允许可以在该小区继续监听G-RNTI加扰的PDCCH和对应的PDSCH接收,但是不能接收C-RNTI加扰的PDCCH和对应的PDSCH接收。且该SCell的第一个激活的DL BWP的带宽必须包含该SCell的初始DL BWP的带宽和/或该SCell的MBS BWP的带宽。
步骤307:UE向gNB发送RRC重配置完成(RRCReconfigurationComplete)消息。

这里,所述广播的MBS业务的标识为TMGI-1。
步骤402:UE向目标gNB发送RRC恢复请求(RRCResumeRequest)消息,1比特指示信息用于指示UE是否正在接收MBS业务。
这里,UE通过SRB0向目标gNB发送RRC恢复请求消息。
这里,RRC恢复请求消息用于确定1比特指示信息,1比特指示信息用于指示UE是否正在接收MBS业务。例如:1比特指示信息的取值为1代表UE正在接收MBS业务,1比特指示信息的取值为0代表UE没有正在接收MBS业务。1比特指示信息的实现有如下几种方式:
1)UE在RRC恢复请求消息中携带1比特指示信息,例如利用RRC恢复请求消息中的空闲比特位(spare bit)来指示这个1比特指示信息。
2)UE通过RRC恢复请求消息对应的CCCH的LCID来指示UE正在接收广播的MBS业务,例如为CCCH定义一个新的LCID,用于指示UE发起RRC连接恢复的时候UE正在接收广播的MBS业务。此时的RRC恢复请求消息的RLC PDU在MAC TB中对应的包头中指示的LCID为上述新定义的LCID。
3)UE在RRC恢复请求消息中携带1比特指示信息,例如利用RRC恢复请求消息中的恢复原因(resume casue)的取值来指示UE正在接收广播的MBS业务。
步骤403:目标gNB向UE发送RRC恢复消息,携带PCell的BWP的配置信息。
这里,目标gNB通过SRB1向UE发送RRC恢复消息。

步骤405:UE通过RRC恢复完成(RRCResumeComplete)消息上报UE感兴趣或者正在接收的MBS业务的标识信息。
这里,UE通过SRB1发送RRC恢复完成消息。
步骤406:gNB向UE发送RRC重配置(RRCReconfiguration)消息,携带专用下行BWP的配置信息。
这里,gNB通过SRB1向UE发送RRC重配置消息。
这里,gNB获取到关于UE感兴趣或者正在接收的MBS业务的标识信息后,通过RRC重配置消息配置专用下行BWP的配置信息,具体地:
gNB在给UE配置PCell的专用DL BWP时,专用DL BWP的带宽包含PCell的初始DL BWP的带宽和/或PCell的MBS BWP的带宽。或者,
gNB可以指示UE在某个SCell上接收MBS业务,配置该Scell的专用DL BWP的带宽包含该SCell的初始DL BWP的带宽和/或该SCell的MBS BWP的带宽。
进一步,如果UE在SCell上接收广播的MBS业务,则该SCell不能被去激活,不能配置dormant BWP(即该SCell不能处于具有休眠行为的激活状态)。或者,如果UE在SCell上接收广播的MBS业务,则如果SCell被去激活,或者配置dormant BWP并激活了dormant BWP,则UE仅允许可以在该小区继续监听G-RNTI加扰的PDCCH和对应的PDSCH接收,但是不能接收C-RNTI加扰的PDCCH和对应的PDSCH接收。且该SCell的第一个激活的DL BWP的带宽必须包含该SCell的初始DL BWP的带宽和/或该SCell的MBS BWP的带宽。

步骤501:UE处于RRC非激活状态,UE正在接收广播的MBS业务。
这里,所述广播的MBS业务的标识为TMGI-1。
步骤502:UE接收目标gNB发送的系统广播消息,配置第一关联关系和/或第二关联关系。
这里,“关联关系”也可以称为“映射关系(mapping relationship)”。
这里,第一关联关系为preamble和/或RO(rach occasion)资源与MBS业务是否正在进行之间的关联关系。第二关联关系为preamble和/或RO(rach occasion)资源与MBS业务标识(即MBS业务的标识信息)之间的关联关系。
需要说明的是,上述步骤501和步骤502没有先后顺序。
步骤503:UE向目标gNB发送MSG1。
