如图1所示，通信系统100可以包括终端设备110和网络设备120。网络设备120可以通过空口与终端设备110通信。终端设备110和网络设备120之间支持多业务传输。
应理解，本申请实施例仅以通信系统100进行示例性说明，但本申请实施例不限定于此。也就是说，本申请实施例的技术方案可以应用于各种通信系统，例如：长期演进(Long Term Evolution，LTE)系统、LTE时分双工(Time Division Duplex，TDD)、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、物联网(Internet of Things，IoT)系统、窄带物联网(Narrow Band Internet of Things，NB-IoT)系统、增强的机器类型通信(enhanced Machine-Type Communications，eMTC)系统、5G通信 系统(也称为新无线(New Radio，NR)通信系统)，或未来的通信系统等。

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的相关技术进行说明，以下相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。
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。
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 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。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”的描述也可以被替换为“MBMS”。
在NR系统中，很多场景需要支持组播类型和广播类型的业务需求，例如车联网中，工业互联网中等。所以在NR中引入组播类型和广播类型的MBS业务是有必要的。需要说明的是，组播类型的MBS业务是指通过组播方式传输的MBS业务。广播类型的MBS业务是指通过广播方式传输的MBS业务。
在NR系统中，对于组播类型的MBS业务来说，MBS业务是发给某个组中的所有终端设备。终端设备在RRC连接状态下接收组播类型的MBS业务，终端设备可以通过点对多点(Point-To-Multipoint，PTM)方式或者点对点(Point-To-Point，PTP)方式接收组播类型的MBS业务数据。其中，参照图2，PTM方式的MBS业务数据通过网络侧配置的G-RNTI来加扰对应的调度信息，PTP方式的MBS业务数据通过C-RNTI来加扰对应的调度信息。
对于组播类型的MBS业务来说，基站从共享隧道(tunnel)接收核心网下发的MBS业务后，可以将该MBS业务通过空口下发给一个组中的所有终端设备。这里，基站可以通过PTP方式和/或PTM方式将MBS业务下发给一个组中的所有终端设备。例如：一个组包括终端设备1、终端设备2和终端设备3，基站可以通过PTP方式将MBS业务下发给终端设备1，通过PTP方式将MBS业务下发给终端设备2，通过PTP方式将 MBS业务下发给终端设备3；或者，基站可以通过PTP方式将MBS业务下发给终端设备1，通过PTM方式将MBS业务下发给终端设备2和终端设备3；或者，基站可以通过PTM方式将MBS业务下发给终端设备1，终端设备2以及终端设备3。在核心网到基站之间采用一个共享的GTP隧道(Shared GTP tunnel)来传输MBS业务，即无论是PTM方式的MBS业务还是PTP方式的MBS业务都是共享这个GTP隧道的。基站按照PTM方式下发MBS业务数据给UE1和UE2，以及按照PTP方式下发MBS业务数据给UE3。
对于组播类型的MBS业务(简称为MBS组播业务)来说，为了终端设备节能引入了非连续接收(Discontinuous Reception，DRX)机制。为便于区别，将用于MBS组播业务接收的DRX称为MBS DRX(或者多播DRX(multicast DRX))，将用于传统的单播业务接收的DRX称为单播DRX，MBS DRX和单播DRX是相互独立的。作为示例，MBS DRX相关的参数可以参照以下表1所示，网络侧可以通过RRC信令配置表1所示的参数，从而通过这些参数控制MBS DRX操作，需要说明的是，MBS DRX是per G-RNTI或per G-CS-RNTI配置的。对于终端设备来说，DRX激活时间包括以下定时器运行的时间：drx-onDurationTimerPTM、drx-InactivityTimerPTM、drx-RetransmissionTimer-DL-PTM。

表1
一方面，MBS业务传输过程中，存在PTP用于PTM重传的场景，即一个MBS业务的传输块(Transport Block，TB)，网络侧通过PTM方式(也即G-RNTI加扰对应的调度信息)进行初始传输(简称为初传)，如果终端设备接收失败反馈否定应答(NACK)，网络侧通过PTP方式(也即C-RNTI加扰对应的调度信息)进行重传输(简称为重传)。此时PTM方式的初传和PTP方式的重传对应相同的HARQ进程标识和新数据指示(New Data Indication，NDI)，即初传的调度信令中携带的的HARQ进程标识和NDI，与重传的调度信令中携带的HARQ进程标识和NDI是相同的。
另一方面，MBS业务传输过程中，对于PTM方式的传输存在HARQ反馈，HARQ反馈的模式包括基于仅否定应答(NACK only)的HARQ反馈模式和基于肯定应答/否定应答(ACK/NACK)的HARQ反馈模式。MBS业务的反馈模式可以通过RRC信令配置，且是per G-RNTI或者per G-CS-RNTI配置的。然而，如何支持HARQ反馈的使能或者去使能尚未明确。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，通过RRC信令或者DCI指示HARQ反馈是使能的(enable)还是去使能的(disable)，进一步，明确了HARQ反馈在去使能的时候对于DRX操作的影响。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图3是本申请实施例提供的反馈状态的指示方法的流程示意图，如图3所示，所述反馈状态的指示方法包括以下步骤：
步骤301：终端设备接收网络设备发送的RRC信令，所述RRC信令携带第一指示信息或者第二指示信息，其中，所述第一指示信息用于指示HARQ反馈是使能的或者去使能的；所述第二指示信息用于指示通过DCI来控制HARQ反馈是使能的或者去使能的。
本申请实施例中，网络通过RRC专用信令为终端设备配置MBS业务传输的配置信息，例如包括TMGI、G-RNTI或G-CS-RNTI、用于MBS接收公共频域位置、HARQ反馈模式、数据传输架构方式等。其中，所述HARQ反馈模式例如可以是仅否定应答反馈模式(NACK only based HARQ feedback)，或者是ACK/NACK反馈模式(ACK/NACK based HARQ feedback)。数据传输方式例如可以是PDCP anchor的协议栈方式，PTP用于PTM重传的数据架构传输方式。
需要说明的是，本申请实施例中的HARQ反馈的模式可以是NACK only based HARQ feedback，或者也可以是ACK/NACK based HARQ feedback，无论是何种反馈模式都适用于本申请实施例的技术方案。
本申请实施例中，HARQ反馈模式可以是per G-RNTI配置的或者是per G-CS-RNTI配置的。这里，HARQ反馈模式是per G-RNTI配置的，可以理解为，按照G-RNTI配置HARQ反馈模式，HARQ反馈模式与G-RNTI是关联的。HARQ反馈模式是组-配置调度-无线网络临时标(G-CS-RNTI)配置的，可以理解为，按照G-CS-RNTI配置HARQ反馈模式，HARQ反馈模式与G-CS-RNTI是关联的。其中，G-RNTI用于MBS业务的动态调度，G-CS-RNTI用于MBS业务的半持续(SPS)调度。
