Description
本申请实施例涉及移动通信技术领域,具体涉及一种反馈资源配置方法及通信方法、装置、通信设备。

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。
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。
3GPP版本6(Release 6,R6)中引入了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UE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3GPP R6中的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UE。
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UE的业务连续性基于频率优先级的概念。
在NR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。
在NR中,连接态的单播场景是存在HARQ反馈的。对于NR中的MBMS场景并没有引入反馈机制,也就是终端设备接收MBMS业务是不需要反馈的,MBMS业务数据丢失是没有补救措施的,MBMS业务的传输可靠性无法得到保障。对于NR中的一些场景,例如V2X,工业网互联网等场景,对于组播传输的可靠性要求越来越高,所以针对MBMS引入反馈机制确保业务传输的可靠性(即保证多播组内的所有成员都接收到了业务数据)是需要考虑和引入的。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在组播中引入HARQ反馈和重复发送机制,保证业务数据在组内传输的可靠性。
本申请实施例的技术方案中,定义一个新的SIB(称为第一SIB),参照图2,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。
进一步,第一MCCH中还携带以下至少之一:第一指示信息,所述第一指示信息用于指示(TMGI和/或会话标识对应的)MBMS业务是否需要HARQ反馈;第二指示信息,所述第二指示信息用于指示MBMS业务对应的多播组内的成员个数;第三指示信息,所述第三指示信息用于指示终端设备是否需要进入连接态后接收MBMS业务。这里,终端设备在注册到MBMS业务时,网络设备为注册到MBMS业务的终 端设备分配一个成员索引号。
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,参照图3,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 1PDCCH、MTCH 2PDCCH、…、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。参照图4,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。
图5为本申请实施例提供的反馈资源配置方法的流程示意图一,如图5所示,所述反馈资源配置方法包括以下步骤:
步骤501:网络设备发送第一配置信息,所述第一配置信息用于确定MBMS业务对应的第一反馈资源;所述第一反馈资源用于终端设备发送针对所述MBMS业务的NACK信息。
本申请实施例中,网络设备发送第一配置信息,终端设备接收所述第一配置信息,所述终端设备在所述第一反馈资源上发送NACK信息。进一步,可选地,所述网络设备可以是基站,例如gNB。
本申请实施例中,所述第一配置信息携带在第一MCCH中或第一SIB中。这里,第一MCCH和第一SIB可以参照前述相关描述进行理解。需要指出的是,所述第一MCCH中还携带以下至少之一:第一指示信息,所述第一指示信息用于指示所述MBMS业务是否需要HARQ反馈;第二指示信息,所述第二指示信息用于指示所述MBMS业务对应的多播组内的成员个数;第三指示信息,所述第三指示信息用于指示终端设备是否需要进入连接态后接收所述MBMS业务。进一步,所述网络设备为注册到所述MBMS业务的终端设备分配一个成员索引号。
本申请实施例中,所述第一反馈资源是针对MBMS业务的PUCCH反馈资源。也可以理解为,所述第一反馈资源是组播对应的PUCCH反馈资源。
在本申请一可选实施方式中,所述第一配置信息用于确定第一PUCCH资源集(PUCCH resource set),所述第一PUCCH资源集用于确定所述第一反馈资源。
举个例子:所述第一配置信息用于确定第一索引值,可以通过如下表格1所示的配置列表来确定与所述第一索引值关联的PUCCH反馈资源集。
表1
在本申请另一可选实施方式中,所述第一配置信息用于确定所述第一反馈资源。
本申请实施例中,所述第一反馈资源仅用于反馈NACK信息,不反馈ACK信息。可见,终端设备针对某个数据,如果未正确接收(或者说完整接收)该数据的情况下,会在所述第一反馈资源上发送NACK信息;如果正确接收(或者说完整接收)该数据的情况下,不需要反馈任何信息。
在本申请一可选实施方式中,若所述网络设备在所述第一反馈资源上接收到NACK信息,则所述网络设备重传所述NACK信息对应的业务数据包,所述业务数据包为所述MBMS业务的数据包。可见,只要网络设备在所述第一反馈资源上接收到了NACK信息,就说明有终端设备未正确接收业务数据包,网络设备就会触发HARQ重传;反之,如果网络设备在所述第一反馈资源上未收到NACK信息,则说明全部终端设备都正确接收到业务数据包,网络设备不会触发HARQ重传。
本申请实施例的技术方案还提供一种通信方法,包括:终端设备接收第一配置信息,所述第一配置信息用于确定MBMS业务对应的第一反馈资源;所述终端设备在所述第一反馈资源上发送NACK信息。需要说明的是,这里的第一反馈资源可以参照前述相关描述理解。

步骤601:网络设备发送第一配置信息,所述第一配置信息用于确定MBMS业务对应的多个反馈资源,所述多个反馈资源用于多个终端设备发送针对所述MBMS业务的反馈信息。
本申请实施例中,网络设备发送第一配置信息,终端设备接收所述第一配置信息,所述终端设备从所述多个反馈资源中确定第一反馈资源,在所述第一反馈资源上发送反馈信息。进一步,可选地,所述网络设备可以是基站,例如gNB。
本申请实施例中,所述第一配置信息携带在第一MCCH中或第一SIB中。这里,第一MCCH和第一SIB可以参照前述相关描述进行理解。需要指出的是,所述第一MCCH中还携带以下至少之一:第一指示信息,所述第一指示信息用于指示所述MBMS业务是否需要HARQ反馈;第二指示信息,所述第二指示信息用于指示所述MBMS业务对应的多播组内的成员个数;第三指示信息,所述第三指示信息用于指示终端设备是否需要进入连接态后接收所述MBMS业务。进一步,所述网络设备为注册到所述MBMS业务的终端设备分配一个成员索引号。
本申请实施例中,所述反馈资源是针对MBMS业务的PUCCH反馈资源。也可以理解为,所述反馈资源是组播对应的PUCCH反馈资源。网络设备配置组播对应的多个PUCCH反馈资源。
本申请实施例中,所述多个反馈资源可以通过以下方式来实现配置:
所述第一配置信息用于确定多个PUCCH资源集,所述多个PUCCH资源集中的每个PUCCH资源集用于确定一个反馈资源。
在一可选实施方式中,所述多个PUCCH资源集属于第一配置列表,所述第一配置列表包括N个PUCCH资源集的配置信息,N为等于16的整数。这里,每个PUCCH资源集对应一个索引值,可以通过上述表1来确定多个索引值对应的多个PUCCH资源集。
在另一可选实施方式中,所述多个PUCCH资源集属于第一配置列表,所述第一配置列表包括N个PUCCH资源集的配置信息,N为大于16的整数。具体实现时,对表1中PUCCH资源集的配置进行扩展,从而支持更多数目(大于16)的PUCCH资源集的配置。
所述第一配置信息用于确定至少一个PUCCH资源集,对于所述至少一个PUCCH资源集中的每个PUCCH资源集,所述PUCCH资源集和所述多个终端设备的成员索引号用于确定多个反馈资源。
具体实现时,每个PUCCH资源集在计算Rpucch资源(即反馈资源)的时候,引入成员索引号来扩展使得一个PUCCH资源集可以支持多个成员(即终端设备)的反馈资源。
需要说明的是,所述多个反馈资源和所述多个终端设备的成员索引号具有对应关系。这里,应用层在组建通信组(即多播组)的时候,每个成员有一个索引号,在配置反馈资源的时候,成员索引号和反馈资源一一对应。
在本申请一可选实施方式中,所述网络设备在所述多个反馈资源上接收所述多个终端设备发送的针对所述MBMS业务的ACK信息和/或NACK信息。这里,每个终端设备在接收MBMS业务的时候,会在自身的反馈资源上发送ACK信息或者NACK信息给网络侧,触发网络侧进行重传。
本申请实施例中,触发网络设备重传所述第一数据,可以采用以下任意一种机制:
(A)重传机制一
所述网络设备发送第一数据后,将第一计数器置0,并启动第一定时器;所述第一数据为所述MBMS业务的数据;所述网络设备每次接收到一个针对所述第一数据的ACK信息后,控制所述第一计数器加1;若所述第一计数器的数值等于第一阈值且所述第一定时器处于运行状态,则停止所述第一定时器,并确定所述第一数据被所述多个终端设备正确接收;若所述第一定时器超时,则所述网络设备重传所述第一数据。

在一可选实施方式中,所述第一阈值在第一SIB中或者第一MCCH中配置。
具体实现时,所述第一数据为传输块(Transport Block,TB)。网络设备发送TB后,为每个TB维护一个计数器(counter),同时启动一个定时器(timer),每当接收到一个针对该TB的ACK信息,计数器就加1,在定时器超时之前,当计数器等于多播组内的成员个数或者一个预设值时,则停止定时器;如果定时器超时,则触发该TB的重传。
(B)重传机制二
所述网络设备发送第一数据后,启动第一定时器;所述第一数据为所述MBMS业务的数据;若所述第一定时器超时之前,所述网络设备未接收到针对所述第一数据的NACK信息,则确定所述第一数据被所述多个终端设备正确接收;若所述第一定时器超时之前,所述网络设备接收到针对所述第一数据的NACK信息,则所述网络设备重传所述第一数据。
具体实现时,所述第一数据为传输块TB。网络设备发送TB后,启动一个定时器(timer),在定时器超时之前,如果网络设备没有收到针对该TB的NACK信息,则认为是该TB被正确接收;如果网络设备收到针对该TB的NACK信息,则触发该TB的重传。
本申请实施例的技术方案还提供一种通信方法,包括:终端设备接收第一配置信息,所述第一配置信息用于确定MBMS业务对应的多个反馈资源;所述终端设备从所述多个反馈资源中确定第一反馈资源,在所述第一反馈资源上发送反馈信息。需要说明的是,这里的多个反馈资源可以参照前述相关描述理解。
