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。
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。
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、MBS业务。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“MBMS业务”。
在NR中,终端设备需要在RRC连接态下接收MBS业务,针对MBS业务的可靠性提出了更高的需求。如何使用SPS的方式来传输MBS业务,提高MBS业务传输的可靠性是个需要明确的问题。为此,提出了本申请实施例的以下技术方案。
本申请实施例中,SPS配置的信息可以参照如下表1所示,包括周期(periodicity)信息、HARQ进程(nrofHARQ-Processes,periodicityExt)信息、PUCCH反馈资源(n1PUCCH-AN)信息、MCS(mcs-Table)信息、SPS配置索引(sps-ConfigIndex)信息、HARQ进程标识偏移(harq-ProcID-Offset)信息、HARQ反馈码本(harq-CodebookID)信息、PDSCH聚合因子(pdsch-AggregationFactor)信息等。此外,SPS配置的信息还可以包括其他信息,详见以下关于本申请实施例的描述。
表1
图2是本申请实施例提供的MBS业务的半静态调度方法的流程示意图,如图2所示,所述MBS业务的半静态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配置信息,终端设备接收网络设备发送的第一配置信息,所述第一配置信息用于确定N个半静态调度SPS配置,N为正整数,所述N个SPS配置中的全部或部分用于传输MBS业务。
本申请实施例中,所述网络设备可以是基站,如gNB。
(一)MBS传输的SPS配置
本申请实施例中,MBS传输的SPS配置可以通过第一配置信息来实现。
在一可选方式中,所述第一配置信息携带在RRC信令中。
在一可选方式中,所述第一配置信息携带在BWP配置中或者服务小区配置中。这里,BWP配置例如是BWP-DownlinkDedicated配置,服务小区配置例如是ServingCellConfig。
需要说明的是,如果第一配置信息携带在BWP配置中,则代表网络设备是以BWP为粒度(per BWP)对第一配置信息进行配置。如果第一配置信息携带在服务小区配置中,则代表网络设备是以小区为粒度(per cell)对第一配置信息进行配置。
本申请实施例中,所述第一配置信息用于确定N个SPS配置,N为正整数,所述N个SPS配置中的全部或部分用于传输MBS业务。这里,所述第一配置信息的实现可以有如下方式:
方式一:所述第一配置信息包括第一SPS配置列表,所述第一SPS配置列表中包括N个SPS配置,所述第一SPS配置列表为用于传输MBS业务的专用SPS配置列表。
进一步,可选地,所述N个SPS配置中的每个SPS配置包含第二指示信息,所述第二指示信息用于指示所述SPS配置关联的MBS标识信息。
这里,由于所述第一SPS配置列表为用于传输MBS业务的专用SPS配置列表,因而所述第一SPS配置列表中的全部SPS配置均用于传输MBS业务。
方式二:所述第一配置信息包括第一SPS配置列表,所述第一SPS配置列表中包括N个SPS配置,所述N个SPS配置中的每个SPS配置包含第一指示信息,所述第一指示信息用于指示所述SPS配置是否用于传输MBS业务和/或所述SPS配置关联的MBS标识信息。
进一步,可选地,所述N个SPS配置中的每个SPS配置包含第二指示信息,所述第二指示信息用于指示所述SPS配置关联的MBS标识信息。

需要说明的是,由于SPS配置用于MBS业务传输,因此可以将SPS配置称为“MBS SPS配置”。
(二)激活去激活SPS配置
本申请实施例中,通过DCI激活或者去激活用于传输MBS业务的SPS配置,以下将该DCI称为第一DCI,本申请实施例对DCI的名称不做限制。

需要说明的是,第一DCI还可以用于去激活所述N个SPS配置中的至少一个SPS配置。在MBS业务传输的场景中,被去激活的SPS配置不能再继续用于MBS业务传输。
本申请实施例中,所述第一DCI用于激活至少一个SPS配置,为此,所述第一DCI中,或者MAC CE中,或者RRC信令中需要携带一些信息来指示至少一个SPS配置。在一可选方式中,所述第一DCI或者MAC CE中或者RRC信令携带第一SPS标识列表,所述第一SPS标识列表用于确定需要激活的至少一个SPS配置。在另一可选方式中,所述第一DCI或者MAC CE中或者RRC信令携带第一MBS标识,所述第一MBS标识用于确定需要激活的至少一个SPS配置。
