应理解,本文中术语“系统”和“网络”在本文中常被可互换使用。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):移动性为基于终端设备的小区选择重选,寻呼由核心网(Core Network,CN)发起,寻呼区域由CN配置。基站侧不存在终端设备上下文,不存在RRC连接。
2)RRC_CONNECTED状态(简称为连接(connected)态):存在RRC连接,基站侧和终端设备侧存在终端设备上下文。网络侧知道终端设备的位置是具体小区级别的。移动性是网络侧控制的移动性。终端设备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):移动性为基于终端设备的小区选择重选,存在CN-NR之间的连接,终端设备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,网络侧知道终端设备的位置是基于RAN的寻呼区域级别的。
Figure PCTCN2021085398-appb-000002
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。
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包括第一MCCH的配置信息,这里,第一MCCH为MBMS业务的控制信道,换句话说,第 一SIB用于配置NR MBMS的控制信道的配置信息,可选地,NR MBMS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A,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MBMS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MBMS业务数据(如NR MBMS的业务数据)。换句话说,第一MCCH用于配置NR MBMS的业务信道的配置信息,可选地,NR MBMS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 MBMS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MBMS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。其中,用于调度第一MCCH的PDCCH使用的RNTI使用全网唯一标识,即是一个固定值。用于调度第一MTCH的PDCCH使用的RNTI通过第一MCCH进行配置。
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,通过SIB配置用于调度MCCH的PDCCH(即MCCH PDCCH)以及通知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M个用于调度MTCH的PDCCH(即MTCH 1 PDCCH、MTCH 2 PDCCH、…、MTCH M 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M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。
需要说明的是,虽然上述方案是以MBMS为例进行说明的,但“MBMS”的描述也可以替换为“MBS”。本申请实施例以MBS为例进行说明,“MBS业务”的描述也可以被替换为“MBMS”。
在NR MBS中,MBS业务的传输网络架构如图2所示,5G核心网通过共享GTP隧道传递MBS业务流到5G接入网(如gNB),5G接入网可以判断通过点对点(Point To Point,PTP)方式或者点对多点(Point To Multipoint,PTM)方式传递MBS业务流给终端设备。
对于接收MBS业务的终端设备来说,同时还会接收其他非MBS业务,例如eMBB业务。所以当没有MBS业务传输的时候,终端设备可以被网络侧释放到空闲态或者非激活态或者保持在连接态。在终端设备处于空闲态或者非激活态的情况下,当MBS业务的数据到达时,网络侧可以通过寻呼来唤醒终端设备来接收MBS业务。
在NR中,对应同一寻呼时机(Paging Occasion,PO)的多个用户的寻呼可以复用在一个寻呼消息中,所以一个PO对应的多个用户都会监听MBS业务的寻呼消息,即使某些用户没有参与该MBS业务,MBS业务的寻呼消息也会务唤醒这些用户,对这些用户造成影响,例如造成这些用户费电。此外,NR支持波束扫描(beam sweeping)传输,所以一个寻呼消息在一个小区中会传输多份,具体份数取决于该小区实际传输的同步信号块(SS/PBCH Block,SSB)个数,这样,MBS业务的寻呼消息会有很高的负荷,浪费了无线资源。为此,提出了本申请实施例的以下技术方案。
图3是本申请实施例提供的指示寻呼的方法流程示意图,如图3所示,所述指示寻 呼的方法包括以下步骤:
步骤301:网络设备发送第一DCI,终端设备接收第一DCI,所述第一DCI用于调度寻呼消息,其中,所述第一DCI携带第一指示信息,所述第一指示信息用于指示以下至少之一:所述寻呼消息为MBS寻呼消息;触发所述寻呼消息的MBS业务的信息。
本申请实施例中,网络设备可以是接入网设备。在一些可选实施方式中,网络设备为基站。
本申请实施例中,网络设备发送第一DCI,终端设备接收第一DCI,具体地,所述终端设备在PO中监听并接收所述第一DCI。
本申请实施例中,所述第一DCI携带寻呼消息的调度信息,换句话说,所述第一DCI用于调度寻呼消息。在一些可选实施方式中,所述第一DCI也可以称为寻呼DCI(paging DCI)。
本申请实施例中,所述第一DCI携带第一指示信息,所述第一指示信息用于指示以下至少之一:所述寻呼消息为MBS寻呼消息;触发所述寻呼消息的MBS业务的信息。
在一些可选实施方式中,所述第一指示信息用于指示所述寻呼消息为MBS寻呼消息。换句话说,所述第一指示信息用于指示所述寻呼消息为MBS类型的寻呼消息。
对于终端设备来说,在一些可选实施方式中,若所述终端设备为传统(legacy)类型的终端设备或者未被配置MBS业务的终端设备,则所述终端设备放弃接收所述第一DCI调度的寻呼消息;或者,若所述终端设备被配置了MBS业务或者支持MBS业务,则所述终端设备接收所述第一DCI调度的寻呼消息。
这里,接收第一DCI调度的寻呼消息,也可以理解为,接收第一DCI调度的PDSCH,所述PDSCH用于承载寻呼消息。
这里,传统(legacy)类型的终端设备是指非MBS业务的终端设备(即不接收MSB业务的终端设备),例如eMBB类型的终端设备。
作为示例,所述第一指示信息为1比特信息,1比特信息的取值为第一值用于指示所述寻呼消息为MBS寻呼消息,1比特信息的取值为第二值用于指示所述寻呼消息不是MBS寻呼消息。这里,第一值为1,第二值为0;或者,第一值为0,第二值为1。
在一些可选实施方式中,所述第一指示信息用于指示触发所述寻呼消息的MBS业务的信息。这里,可选地,触发所述寻呼消息的MBS业务的信息包括以下至少之一:MBS业务标识、MBS业务关联信息。
在一些可选实施方式中,所述第一指示信息用于指示触发所述寻呼消息的MBS业务的MBS业务标识。作为示例,所述MBS业务标识包括以下至少之一:TMGI、G-RNTI、MBS会话标识。
对于终端设备来说,在一些可选实施方式中,若所述终端设备为传统类型的终端设备或者未被配置所述MBS业务标识对应的MBS业务的终端设备,则所述终端设备放弃接收所述第一DCI调度的寻呼消息。
对于终端设备来说,在一些可选实施方式中,若所述MBS业务标识对应的MBS业务是所述终端设备感兴趣的MBS业务或者加入的MBS业务或者期望接收的MBS业务,则:
选项1:所述终端设备接收所述第一DCI调度的寻呼消息;或者,
选项2:所述终端设备不接收所述第一DCI调度的寻呼消息,直接发起无线资源控制RRC连接建立过程或者RRC连接恢复过程。
这里,接收第一DCI调度的寻呼消息,也可以理解为,接收第一DCI调度的PDSCH, 所述PDSCH用于承载寻呼消息。
这里,传统类型的终端设备是指非MBS业务的终端设备(即不接收MSB业务的终端设备),例如eMBB类型的终端设备。
在一些可选实施方式中,所述第一指示信息用于指示MBS业务关联信息。其中,所述MBS业务关联信息包括以下至少之一:MBS业务的类型;MBS业务的第一信息,所述第一信息基于MBS业务标识得到。
作为示例,MBS业务的第一信息可以是MBS业务标识的一部分内容。
作为示例,MBS业务的第一信息可以是通过MBS业务标识计算得到,以MBS业务标识为TMGI为例,第一信息=TMGI mod k,其中,k为正整数。
对于终端设备来说,在一些可选实施方式中,所述终端设备基于所述MBS业务关联信息,确定所述寻呼消息是否为自己的寻呼消息;若所述终端设备确定所述寻呼消息不是自己的寻呼消息,则所述终端设备放弃接收所述第一DCI调度的寻呼消息;或者,若所述终端设备确定所述寻呼消息是自己的寻呼消息,则所述终端设备接收所述第一DCI调度的寻呼消息。
这里,MBS业务关联信息的容量(或者说占据的负荷)较小,因此可以有效节省第一DCI的开销。终端设备根据MBS业务关联信息可以判断出寻呼消息是自己的寻呼消息的概率,若概率较大(例如大于或等于指定阈值),则接收第一DCI调度的寻呼消息,通过寻呼消息来进一步判断寻呼消息是否是自己的寻呼消息;若概率较小(例如小于或等于指定阈值),则放弃接收第一DCI调度的寻呼消息。
在一些可选实施方式中,所述第一DCI还携带第一信息域,所述第一信息域能够被传统类型的终端设备解析;其中,所述第一信息域的取值为特定值的情况下,所述传统类型的终端设备不接收所述第一DCI调度的寻呼消息。
作为示例,所述第一信息域为短消息指示(short message indicator)信息域。这里,短消息指示信息域占据2比特。传统类型的终端设备接收到第一DCI后,解析短消息指示信息域中的2比特,若2比特的取值为特定值,例如00或者10,则传统类型的终端设备不接收所述第一DCI调度的寻呼消息。可选地,传统类型的终端设也不解析所述第一指示信息。
本申请实施例的技术方案,用于调度寻呼消息的第一DCI携带第一指示信息,所述第一指示信息用于指示寻呼消息为MBS寻呼消息和/或触发寻呼消息的MBS业务的信息,如此,终端设备可以根据自身情况决定是否监听寻呼消息,降低了MBS寻呼对没有参与MBS业务的终端设备的影响,一方面,降低了空口信令的负荷,另一方面,达到了终端设备省电的目的。
