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。

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,上述方案中的MBMS业务包括但不局限于多播业务、组播业务。本申请实施例以多播业务为例进行说明,“多播业务”的描述也可以被替换为“MBS业务”或者“组播业务”或者“MBMS业务”。
在NR中,终端设备需要在RRC连接态下接收多播业务,针对多播业务的可靠性提出了更高的需求。
对于多播业务的调度方式,主要体现在两个方面,一个是用于传输多播业务的PDSCH的加扰方式,另一个是用于调度PDSCH的PDCCH的加扰方式。如何使得终端设备明确多播业务的调度方式有待解决。
本申请实施例中,PDSCH的加扰方式和PDCCH的加扰方式可以相同,也可以不同。以下给出三种类型的调度方式:
1)C-RNTI加扰的PDCCH用来传输公共的PDSCH的调度信息,即:PDCCH通过C-RNTI加扰,PDSCH通过G-RNTI加扰。
2)G-RNTI加扰的PDCCH用来传输公共的PDSCH的调度信息,即:PDCCH通过G-RNTI加扰,PDSCH通过G-RNTI加扰。
3)C-RNTI加扰的PDCCH用来传输per UE的PDSCH的调度信息,即:PDCCH通过C-RNTI加扰,PDSCH通过C-RNTI加扰。
终端设备如何区分上述三种调度方式是需要明确的,为此,提出了本申请实施例的以下技术方案。
图2是本申请实施例提供的多播业务的调度方法的流程示意图,如图2所示,所述多播业务的调度方法包括以下步骤:
步骤201:网络设备向终端设备发送第一信息,终端设备接收网络设备发送的第一信息,所述第一信息用于确定多播业务的调度方式,所述调度方式用于确定第一PDCCH的加扰方式和/或第一PDSCH的加扰方式;其中,所述第一PDCCH用于调度所述第一PDSCH,所述第一PDSCH用于传输多播业务。
本申请实施例中,网络设备可以是基站,如gNB。
本申请实施例中,网络设备通过第一信息向终端设备指示多播业务的调度方式,终端设备根据 第一信息可以确定第一PDCCH的加扰方式和/或第一PDSCH的加扰方式。这里,所述第一PDCCH用于调度所述第一PDSCH,所述第一PDSCH用于传输多播业务。
需要说明的是,所述第一PDCCH是指多播业务的PDCCH,所述第一PDSCH是指多播业务的PDSCH。在一个示例中,所述第一PDCCH也可以称为MBS PDCCH,所述第一PDSCH也可以称为MBS PDSCH。本申请实施例对于所述第一PDCCH和所述第一PDSCH的名称不做限制。
本申请实施例中,所述第一PDSCH用于传输多播业务,所述第一PDCCH用于调度所述第一PDSCH,即所述第一PDCCH用于传输所述第一PDSCH的调度信息。
需要说明的是,公共的PDCCH/PDSCH是指,该PDCCH/PDSCH通过G-RNTI加扰。多播组(如MBS组)内的全部终端设备都能识别该PDCCH/PDSCH。公共的PDCCH/PDSCH也可以称为组公共的PDCCH/PDSCH。
需要说明的是,UE专有的PDCCH/PDSCH是指,该PDCCH/PDSCH通过C-RNTI加扰。多播组(如MBS组)内仅目标终端设备能够识别该PDCCH/PDSCH,多播组内除目标终端设备以外的其他终端设备不能识别该PDCCH/PDSCH。UE专有的PDCCH/PDSCH也可以称为per UE的PDCCH/PDSCH。
需要说明的是,本申请实施例中对于“G-RNTI”的描述也可以替换为组公共RNTI(group-common RNTI),对于“C-RNTI”的描述也可以替换为“UE-specific RNTI”。
以下对网络设备如何通过第一信息向终端设备指示多播业务的调度方式进行说明。

对于方式一来说,第一PDCCH通过C-RNTI加扰,第一PDCCH调度的第一PDSCH的加扰方式通过第一PDCCH承载的第一DCI携带的第一信息来指示,例如通过第一DCI中的1比特信息专用于指示第一PDCCH调度的第一PDSCH使用的是C-RNTI加扰还是G-RNTI加扰。在一个示例中,1比特信息的取值为1(或者0)表示第一PDCCH调度的第一PDSCH使用的是C-RNTI加扰,1比特信息的取值为0(或者1)表示第一PDCCH调度的第一PDSCH使用的是G-RNTI加扰。
本申请实施例中,通过DCI的方式指示多播业务的调度方式,可以实现灵活可变的调度方式。
