图1是本申请实施例的一个系统架构的示意图。
如图1所示,所述系统架构100可包括:终端设备、接入网设备、多小区/多播协调实体(Multi-cell/multicast Coordination Entity,MCE)、移动性管理网元(Mobility Management Entity,MME)、归属签约用户服务器(Home Subscriber Server,HSS)、策略与计费规则功能(Policy and Charging Rules Function,PCRF)、服务/公共数据网关(Serving/PDN Gateway,S/P-GW)、集群通信应用服务器(Group Communication Service Application Server,GCS AS)、广播多播服务中心(Broadcasting multicast Service Center,BM-SC)、多媒体广播多播服务网关(Multimedia Broadcast Multicast Service Gateway,MBMS-GW)。
其中,所述系统架构100中的各个节点或网元之间可以进行通信。例如,所述SC-PTM100中的各个节点或网元可以通过各种类型的接口进行通信。
例如,所述终端设备可以通过Uu接口与接入网设备通信;所述接入网设备可以通过M2接口与MCE通信,还可以通过S1-MME接口与所述MME通信,还可通过M1接口与所述MBMS-GW通信,还可通过S1-U接口与所述S/P-GW通信;所述MCE可通过M3接口与MME通信;所述MME可通过S6a接口与所述HSS通信,还可通过S-11接口与所述S/P-GW通信,还可通过Sm接口与所述MBMS-GW通信;所述S/P-GW还可通过SGi接口与GCS AS通信,还可通过Gx接口与PCRF通信;所述PCRF可通过Rx接口与GCS AS通信;所述GCS AS还可通过MB2-C接口和MB2-U接口与BM-SC通信;所述BM-SC通过SGimb接口和SGmb与所述MBMS-GW通信。
应理解,上述涉及的接口可以是通信标准中规定或定义的接口,以实现各个节点或网元之间的数据或信令的传输。
需要说明的是,本申请对上述各个节点或网元的具体实现形式不做限定。
例如,所述接入网设备可以是长期演进(Long Term Evolution,LTE)系统中的演进型基站(Evolutional Node B,eNB或eNodeB),或者是下一代无线接入网(Next Generation Radio Access Network,NG RAN)设备,或者是NR系统中的基站(gNB),或者是云无线接入网络(Cloud Radio Access Network,CRAN)中的无线控制器,或者该网络设备120可以为中继站、接入点、车载设备、可穿戴设备、集线器、交换机、网桥、路由器,或者未来演进的公共陆地移动网络(Public Land Mobile Network,PLMN)中的网络设备等。
再如,上述终端设备可以是任意终端设备,其包括但不限于与网络设备120或其它终端设备采用有线或者无线连接的终端设备。例如,所述终端设备可以指接入终端、用户设备(User Equipment,UE)、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。接入终端可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol,SIP)电话、无线本地环路(Wireless Local Loop,WLL)站、个人数字处理(Personal Digital Assistant,PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备、5G网络中的终端设备或者未来演进网络中的终端设备等。再如,所述终端设备可以用于设备到设备(Device to Device,D2D)通信。
作为示例,所述系统架构100可以是单小区点到多点(Single Cell Point To Multiploint,SC-PTM)。SC-PTM可以是基于MBMS网络架构。
多媒体广播多播服务(Multimedia Broadcast Multicast Service,MBMS)是在3GPP Release 6中引入的一项业务。多媒体广播多播服务是一种通过共享网络资源从一个数据源向多个用户设备传送数据的技术,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,在无线接入网长期演进标准(Long Term Evolution,LTE)项目中,3GPP提出增强对下行高速多媒体广播多播服务业务的支持能力,并确定了对物理层和空中接口的设计要求。
E-MBMS是R9引入到LTE网络的,E-MBMS提出了单频网(Single Frequency Network,SFN)的概念,即采用统一频率在所有小区同时发送数据,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。并基于IP(Internet Protocol)多播协议实 现业务的广播和多播。
R13中,引入了SC-PTM,SC-PTM基于MBMS网络架构。可选的,MCE决定采用SC-PTM传输方式还是多媒体广播多播业务单频网络(Multimedia Broadcast multicast service Single Frequency Network,MBSFN)传输方式。
图2是本申请实施例提供的SC-PTM的逻辑信道和物理信道的示意图。
如图2所示,下行逻辑信道可包括单小区多播控制信道(Single Cell Multicast Control Channel,SC-MCCH)和单小区多播业务信道(Single Cell Multicast Transport Channel,SC-MTCH)。例如,SC-MCCH的逻辑信道标识(LCID)为11001,SC-MTCH的LCID为11001,所述SC-MCCH和所述SC-MTCH均可以映射到下行共享信道(DL-SCH)上,例如,物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。可选的,SC-MCCH和SC-MTCH不支持混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)操作。
此外,如图2所示,下行逻辑信道还可包括:多播控制信道(Multicast Control Channel,MCCH)、多播业务信道(Multicast Transport Channel,MTCH)、寻呼控制信道(Paging Control Channel,PCCH)、公共控制信道(Common Control Channel,CCCH)、专用控制信道(Dedicated Control Channel,DCCH)、广播控制信道(Broadcast Control Channel,BCCH)以及专用业务信道(Dedicated Traffic Channel,DTCH)中的至少一项。此外,下行传输信道还可包括:广播信道(Broadcast Channel,BCH)、寻呼信道(Paging Channel,PCH)以及多播信道(Multicast Channel,MCH)中的至少一项。
另外,SC-MCCH的配置信息可携带在可以通过系统信息块(System Information Block,SIB)中。例如,SIB20可包括SC-MCCH的配置信息。可选的,一个小区只有一个SC-MCCH。配置信息可包括:SC-MCCH的修改周期,重复周期,以及无线帧和子帧配置信息。可选的,所述SC-MCCH的修改周期可通过DCI 1C中的8个bit中的一个bit来指示变更通知。可选的,所述修改周期的边界可以定义为SFN mod m=0,其中m是SIB20中配置的修改周期(sc-mcch-ModificationPeriod)。
图3是本申请实施例提供的配置传输机制(configuration transmission mechanism)的示意图。
如图3所示,SIB20可配置(Config)SC-MCCH PDCCH,还可配置通知PDCCH。可选的,所可通过单小区无线网络临时标识(Single Cell RNTI,SC-RNTI)加扰所述SC-MCCH PDCCH,和/或,可通过单小区通知无线网络临时标识(Single Cell Notification RNTI,SC-N-RNTI)加扰所述通知PDCCH。所述SC-MCCH PDCCH中的下行控制信息(Downlink Control Information,DCI)可用于调度SC-MCCH PDSCH。所述SC-MCCH PDSCH可配置(Config)SC-MTCH 1~SC-MTCH M,其中,所述SC-MTCH 1~SC-MTCH M可包括SC-MTCH 1PDCCH~SC-MTCH M PDCCH,所述SC-MTCH 1PDCCH~SC-MTCH M PDCCH中的DCI可用于调度SC-MTCH 1PDSCH~SC-MTCH M PDSCH。可选的,所述PDCCH~SC-MTCH M PDCCH可分别通过群组无线网络临时标识符(Group RNTI,G-RNTI)G-RNTI 1~-RNTI M加扰。可选的,所述SC-MTCH 1PDSCH~SC-MTCH M PDSCH可分别携带临时移动组标识(Temporary Mobile Group Identity,TMGI)1~TMGI M。
5G的主要应用场景包括:增强移动超宽带(Enhance Mobile Broadband,eMBB)、低时延高可靠通信(Ultra-Reliable and Low Latency Communication,URLLC)、大规模机器类通信(massive machine type of communication,mMTC)。
其中,eMBB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。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,可以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网络环境中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,定了一个新的无线资源控制(Radio Resource Control,RRC)状态,即RRC_INACTIVE(去激活)状态。这种状态有别于RRC_IDLE(空闲)和RRC_CONNECTED(连接)状态。
在RRC_IDLE状态下: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接入层(Access Stratum,AS)上下文,也不存在RRC连接。
在RRC_CONNECTED状态下:存在RRC连接,基站和UE存在UE AS上下文。网络设备知道UE的位置是具体小区级别的。移动性是网络设备控制的移动性。UE和基站之间可以传输单播数据。
RRC_INACTIVE:移动性为基于UE的小区选择重选,存在CN-NR之间的连接,UE AS上下文存在某个基站上,寻呼由无线接入网(Radio Access Network,RAN)触发,基于RAN的寻呼区域由RAN管理,网络设备知道UE的位置是基于RAN的寻呼区域级别的。
在NR中,RRC连接状态的单播是存在HARQ-ACK信息反馈的。但在其他系统的组播广播并没有引入反馈机制,也就是UE接收组播或者广播的业务是不需要反馈的。在NR中的一些业务,例如V2X,工业网互联网等场景下,需要通过组播的方式传输,由于这些业务对可靠性要求越来越高,因此,如何在针对组播或广播进行反馈是本领域急需解决的技术问题。
本申请中,针对NR MBMS中的组播广播业务引入了反馈机制。
具体的,针对NR MBMS系统,提出了四种反馈机制,以确保业务传输可靠性,使得网络可以根据反馈信息确定是否需要发送重传。具体地,所述四种反馈机制可以包括以下反馈机制:
反馈机制1:仅反馈NACK信息。终端如果没有正确接收数据,则反馈NACK,如果正确接收数据,则不反馈。这种反馈机制中,所有的终端或者一组终端共享一个承载NACK的PUCCH资源。
反馈机制2:反馈NACK信息或ACK信息。终端如果没有正确接收数据,则反馈NACK,如果正确接收数据,则反馈ACK。这种反馈机制中,所有需要反馈NACK的终端或一组需要反馈NACK的终端共享一个承载NACK的PUCCH资源,且所有需要反馈ACK的终端或一组需要反馈ACK的终端共享一个承载ACK的PUCCH资源。
反馈机制3:反馈NACK信息或ACK信息。终端如果没有正确接收数据,则反馈NACK,如果正确接收数据,则反馈ACK。这种反馈机制中,所有需要反馈NACK的终端或一组需要反馈NACK的终端共享一个承载NACK的反馈资源,每个需要反馈ACK的终端有独立的承载ACK的PUCCH资源。
反馈机制4:反馈NACK信息或ACK信息。终端如果没有正确接收数据,则反馈NACK,如果正确接收数据,则反馈ACK。这种反馈机制中,每个需要反馈NACK的终端有独立的承载NACK的PUCCH资源,每个需要反馈ACK的终端有独立的承载ACK的PUCCH资源。
但是,针对组播或广播业务,考虑到基于业务的可靠性要求,可靠性要求较高的业务基于反馈机制可提高业务传输的可靠性,但是,针对可靠性要求较低的业务,并不需要引入反馈机制。基于此,本申请提供了一种激活(enable)或去激活(disable)上行反馈的方法,由此,能够在保证业务传输的可靠性的基础上,降低终端设备的功耗以及资源开销。
图4是本申请实施例提供的无线通信方法200的示意性流程图。所述方法200可由终端设备和网络设备执行。例如,图1所示的终端设备和网络设备。
如图4所示,所述方法200可包括:
S210,接收下行控制信息(Downlink Control Information,DCI),所述DCI用于指示激活或去激活上行反馈。
具体而言,终端设备接收网络设备发送的所述DCI,并基于所述DCI确定是否激活或去激活上行反馈。换言之,所述DCI用于指示激活上行反馈的情况下,网络设备可接收反馈信息,并根据上行反馈确定是否需要发送重传数据,以提升业务传输的可靠性。
通过DCI指示激活或去激活上行反馈,在激活上行反馈的情况下,使得网络可以根据上行反馈确定是否需要发送重传数据,能够确保业务传输的可靠性,在去激活上行反馈的情况下,避免了发送反馈信息,能够减低终端设备的功耗以及资源开销。特别是,针对组播或广播业务,可以基于业务的可靠性要求激活或去激活上行反馈,由此,能够在保证业务传输的可靠性的基础上,降低终端设备的功耗以及资源开销。
需要说明的是,本申请实施例中,所述DCI具体可以用于指示激活使用具体的上行反馈方式,如DCI用于指示激活上述四种反馈机制中的至少一种反馈机制的上行反馈。例如,所述DCI可以用于指示激活使用上述反馈机制1的上行反馈。所述DCI具体可以用于指示去激活使用上述四种反馈机制中的至少一种反馈机制的上行反馈。例如,所述DCI可以用于指示去激活使用上述反馈机制1的上行反馈。再如,所述DCI可以用于指示指示去激活使用上述四种反馈机制中的任一种反馈机制的上行反馈,即所述DCI用于指示去激活所有的反馈机制。此外,也可以采用其他信令或消息指示激活或去激活上行反馈,例如,无线资源控制(Radio Resource Control,RRC),本申请实施例对此不作具体限定。此外,本申请实施例中的“指示”可以是直接指示,也可以是间接指示,还可以是表示具有关联关系。举例说明,A指示B,可以表示A直接指示B,例如B可以通过A获取;也可以表示A间接指示B,例如A指示C,B可以通过C获取;还可以表示A和B之间具有关联关系。
在本申请的一些实施例中,所述DCI用于调度用于承载多媒体广播多播服务(Multimedia Broadcast Multicast Service,MBMS)数据的物理下行共享信道(Physical Downlink Shared Channel,PDSCH)。
在本申请的一些实施例中,所述DCI包括的信息域的取值用于指示激活或去激活上行反馈。
换言之,所述DCI可包括用于指示激活或去激活上行反馈的指示信息。
在一种实现方式中,所述DCI包括用于上行反馈指示的第一信息域,所述第一信息域的取值用于指示激活或去激活上行反馈。
例如,所述第一信息域的取值为第一值的情况下,所述第一信息域用于指示激活上行反馈;或者,所述第一信息域的取值为第二值的情况下,所述第一信息域用于指示去激活上行反馈。
换言之,所述DCI可包括用于指示激活或去激活上行反馈的指示信息,且所述指示信息携带在所述指示信息专用的所述第一信息域内。可选的,该第一信息域也可称为上行反馈激活指示信息域。可选的,所述第一信息域包括1比特,例如,所述第一信息域的取值为1表示激活上行反馈,所述第一信息域的取值为0表示去激活上行反馈,当然,也可以取值为0表示激活上行反馈,取值为1表示去激活上行反馈,本申请实施例对此不作具体限定。
在一种实现方式中,所述DCI包括用于调整上行发送功率的发送功率控制(transmit power control,TPC)信息域,所述TPC信息域的取值用于指示激活或去激活上行反馈。例如,在DCI中包括用于调整物理上行控制信道(Physical Uplink Control Channel,PUCCH)或物理上行共享信道(Physical Uplink Shared Channel,PUSCH)的发送功率的TPC信息域,该TPC信息域用于指示激活或去激活上行反馈。
例如,所述TPC信息域的取值为第三值的情况下,所述TPC信息域用于指示激活上行反馈;或者,所述TPC信息域的取值为第四值的情况下,所述TPC信息域用于指示去激活上行反馈。再如,所述TPC信息域的取值为第三值的情况下,所述TPC信息域用于指示激活使用目标反馈机制的上行反馈;或者,所述TPC信息域的取值为第四值的情况下,所述TPC信息域用于指示去激活上行反馈。
换言之,所述DCI可包括用于指示激活或去激活上行反馈的指示信息,且所述指示信息携带在TPC信息域。
在调度MBMS业务的DCI中,接收端终端通常是一组UE,此时通过一个DCI调度MBMS业务的同时,如果激活上行反馈,由于不同的终端可能需要不同的功率调整,因此,无法通过DCI中的TPC命令调整所有需要进行上行反馈的终端的功率,因此,可以复用TPC信息域用于指示是否激活上行反馈;当该DCI用于调度MBMS业务时,可以使用群组无线网络临时标识(Groupcast Radio Network Temporary Identifier,G-RNTI),多播无线网络临时标识(Multicast RNTI,M-RNTI)或广播无线网络临时标识(Broadcast RNTI,B-RNTI)加扰,调度的MBMS数据也使用相应的RNTI加扰。可选的,该TPC信息域包括2比特,例如,该DCI中的TPC信息域的取值为00时,表示去激活上行反馈,取值为01时,表示激活上行反馈,取值10和11可以做为预留值,不用于指示具体信息。进一步的,可以通过DCI中的TPC信息域指示是否激活上行反馈以及具体的上行反馈方式。例如如下表所示:
表1
TPC | 00 | 01 | 10 | 11 |
上行反馈 | 去激活 | 激活 | 激活 | 激活 |
反馈方式 | / | 方式1 | 方式2 | 方式1和方式2 |
如表1所示,方式1指只反馈NACK的反馈机制,方式2指反馈ACK或NACK的反馈机制,所述DCI中的TPC信息域的取值为00时,表示去激活上行反馈,所述DCI中的TPC信息域的取值为01时,表示激活使用方式1的上行反馈,所述DCI中的TPC信息域的取值10时,表示激活使用方式2的上行反馈,所述DCI中的TPC信息域的取值为11时,表示激活使用方式1的上行反馈和时方式2的上行反馈。当然,方式1和方式2仅为本申请的示例,也可以通过其他方式指示具体的反馈方式,本申请实施例对此不作具体限定。
在一种实现方式中,所述DCI包括用于确定PUCCH传输资源或PUCCH传输资源集合的第二信息域,所述第二信息域的取值用于指示激活或去激活上行反馈。
例如,所述第二信息域的取值为第五值的情况下,所述第二信息域用于指示激活上行反馈;或者,所述第二信息域的取值为第六值的情况下,所述第二信息域用于指示去激活上行反馈。例如,所述第二信息域包括PUCCH资源指示(PUCCH resource indicator)信息域或PDSCH到HARQ反馈的定时指示(PDSCH-to-HARQ_feedback timing indicator)信息域。在一种实现方式中,该PUCCH资源指示(PUCCH resource indicator)信息域和PDSCH到HARQ反馈的定时指示(PDSCH-to-HARQ_feedback timing indicator)信息域联合指示激活或去激活上行反馈。
换言之,所述DCI可包括用于指示激活或去激活上行反馈的指示信息,且所述指示信息携带在第二信息域。或者说,在所述DCI中包括第二信息域,所述第二信息域用于确定PUCCH传输资源(或PUCCH传输资源集合),可根据第二信息域确定是否激活或去激活上行反馈。
在一种实现方式中,所述DCI包括第三信息域和第四信息域,所述第三信息域的取值和所述第四 信息域的取值用于指示激活或去激活上行反馈。例如,所述第三信息域或第四信息域可以是TPC信息域,还可以是上述第二信息域(例如PUCCH资源指示信息域或PDSCH到HARQ反馈的定时指示信息域),本申请实施例对此不作具体限定。
例如,所述第三信息域的取值为第七值且所述第四信息域的取值为第八值的情况下,所述第三信息域和所述第四信息域用于指示激活上行反馈;或者,所述第三信息域的取值不是第七值和/或所述第四信息域的取值不是第八值的情况下,所述第三信息域和所述第四信息域用于指示去激活上行反馈。
换言之,所述DCI可包括用于指示激活或去激活上行反馈的指示信息,且所述指示信息携带在第三信息域和第四信息域。或者说,第三信息域和第四信息域用于联合指示激活或去激活上行反馈。当然,也可以是DCI中的至少两个信息域的取值用于指示激活或去激活上行反馈,本申请对此不作具体限定。
在本申请的一些实施例中,所述DCI的格式用于指示激活或去激活上行反馈。
例如,所述DCI的格式为第一格式的情况下,所述DCI用于指示所述激活上行反馈;或者,所述DCI的格式为第二格式的情况下,所述DCI用于指示所述去激活上行反馈。换言之,至少有两种DCI可用于调度承载MBMS业务的PDSCH,当使用第一种DCI调度承载MBMS的PDSCH时,指示激活上行反馈,当使用第二种DCI调度承载MBMS的PDSCH时,指示去激活上行反馈。
需要说明的是,本申请实施例对DCI的具体格式不作限定。例如,在NR中,针对单播业务定义了不同的DCI格式,例如,对于下行调度,可以采用DCI格式1-0或1-1,对于上行调度,可以采用DCI格式0-0或0-1;其中DCI格式1-0还用于调度一些公共信息,如SIB信息等,此时终端被配置SI-RNTI,根据该SI-RNTI去检测DCI格式1-0,本申请实施例中的DCI的格式可以采用针对单播业务定义的DCI格式,也可以引入新的DCI格式,本申请实施例对此不做限定。
在本申请的一些实施例中,用于加扰所述DCI的无线网络临时标识RNTI用于指示激活或去激活上行反馈。
例如,用于加扰所述DCI的RNTI为第一RNTI的情况下,所述DCI用于指示激活上行反馈;或者,用于加扰所述DCI的RNTI为第二RNTI的情况下,所述DCI用于指示去激活上行反馈。可选的,所述第一RNTI包括群组无线网络临时标识G-RNTI、广播无线网络临时标识B-RNTI或多播无线网络临时标识M-RNTI。
对于单播业务,网络为终端配置C-RNTI,网络与该终端之间的数据传输通过C-RNTI加扰。当终端支持MBMS业务时,网络为该终端配置公共RNTI(Common RNTI),如G-RNTI,M-RNTI或B-RNTI,并且DCI使用该公共RNTI加扰,该DCI调度的MBMS数据也用相应的公共RNTI加扰。例如,网络对调度不同的MBMS业务的DCI使用不同的RNTI加扰,如果终端使用第一RNTI加扰DCI,指示激活上行反馈,使用第二RNTI加扰,指示去激活上行反馈。
在本申请的一些实施例中,用于加扰所述DCI的扰码序列用于指示激活或去激活上行反馈。
例如,用于加扰所述DCI的扰码序列为第一序列的情况下,所述DCI用于指示激活上行反馈;或者,用于加扰所述DCI的扰码序列为第二序列的情况下,所述DCI用于指示去激活上行反馈。

例如,所述第一参数为第九值的情况下,所述DCI用于指示激活上行反馈;或者,所述第一参数为第十值的情况下,所述DCI用于指示去激活上行反馈。
由于DCI的信息比特序列或编码后的比特序列需要进行加扰处理以提高抗干扰性能,本申请实施例中,可以根据用于加扰DCI的扰码序列确定是否激活上行反馈。例如,如果DCI使用第一序列加扰,指示激活上行反馈,使用第二序列加扰,指示去激活上行反馈。进一步的,扰码序列可以根据第一参数确定,如第一参数取值为第一值时,对应第一序列,取值为第二值时,对应第二序列。因此,可以根据用于生成扰码序列的第一参数确定激活或去激活上行反馈。
在本申请的一些实施例中,用于承载所述DCI的PDCCH的聚合等级(Aggregation Level,AL)用于指示激活或去激活上行反馈。

例如,PDCCH的聚合等级可包括{1,2,4,8,16}个CCE,当网络发送用于调度承载MBMS业务的DCI的PDCCH时,如果该PDCCH聚合等级对应4个CCE,则表示激活上行反馈,如果对应8个CCE,则表示去激活上行反馈。当然,4和8仅为本申请的示例,不应理解为对本申请的限制。
在本申请的一些实施例中,所述DCI的类型用于指示激活或去激活上行反馈。
例如,所述DCI的类型为专用DCI的情况下,所述DCI用于指示激活上行反馈;或者,所述DCI的类型为公共DCI的情况下,所述DCI用于指示去激活上行反馈。可选的,所述专用DCI通过小区无线网络临时标识C-RNTI加扰,所述公共DCI通过公共RNTI加扰。
换言之,网络调度MBMS业务时,可以采用公共DCI(即为接收端终端发送同一个DCI)承载调度信息,或者采用UE专有的DCI(即为不同接收端发送不同的DCI)承载调度信息。如果采用公共DCI调度,指示去激活上行反馈,如果采用UE专有的DCI调度,指示激活上行反馈。例如,该UE专有的DCI是通过C-RNTI加扰,公共DCI是通过公共RNTI加扰(如G-RNTI,M-RNTI或B-RNTI)。
在本申请的一些实施例中,所述DCI的搜索空间的类型用于指示激活或去激活上行反馈。
例如,所述DCI的搜索空间的类型为专用搜索空间USS的情况下,所述DCI用于指示激活上行反馈;或者,所述DCI的搜索空间的类型为公共搜索空间CSS的情况下,所述DCI用于指示去激活上行反馈。
换言之,搜索空间类型包括公共搜索空间(CSS,Common search space)和UE专有搜索空间(UE-specific search space),如果调度MBMS业务的DCI在CSS中发送,指示去激活上行反馈,如果在USS中发送,指示激活上行反馈。
