- 5G Enhanced Mobile Broadband
- URLLC Ultra-Reliable Low-Latency Communications
- mMTC Massive Machine-Type Communications
- eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly.
- eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios.
- Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc.
- Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.
- NR In the early deployment of NR, complete NR coverage is difficult to obtain, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large amount of LTE is deployed below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, and the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investment in LTE, a tight interworking mode between LTE and NR is proposed.
- RRC Radio Resource Control
- RRC_INACTIVE Radio Resource Control
- RRC_IDLE state (abbreviated as idle state): mobility is UE-based cell selection and reselection, paging is initiated by the Core Network (Core Network, CN), and the paging area is configured by the CN. There is no UE context and no RRC connection on the base station side.
- RRC_CONNECTED state (referred to as connected state for short): There is an RRC connection, and UE context exists on the base station side and the UE side. The network side knows that the location of the UE is of a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.

- the maximum channel bandwidth in 5G can be 400MHz (ie, broadband). Compared with the maximum channel bandwidth of 20MHz in LTE, the maximum channel bandwidth in 5G is very large. If the UE keeps working on a broadband carrier (that is, the maximum channel bandwidth), the power consumption of the UE is very large. Therefore, it is recommended that the radio frequency bandwidth of the UE can be adjusted according to the actual throughput of the UE. For this reason, the concept of BWP is introduced. The motivation for introducing BWP is to optimize the power consumption of the UE. For example, the rate requirement of the UE is very low. You can configure the UE with a smaller bandwidth (that is, a BWP with a smaller bandwidth).

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)。
As people speed, latency, high-speed mobility, energy efficiency and the future of life in the pursuit of the business of diversity, complexity, for the third Generation Partnership Project (3 rd Generation Partnership Project, 3GPP ) ISO began the development of 5G . The main application scenarios of 5G are: Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), 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。On the one hand, eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., its capabilities and requirements are also quite different, so it cannot be generalized and must be analyzed in detail in conjunction with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, telemedicine operations (surgery), traffic safety protection, etc. Typical features of mMTC include: high connection density, small data volume, delay-insensitive services, low-cost modules and long service life.
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。In the early deployment of NR, complete NR coverage is difficult to obtain, so the typical network coverage is wide-area LTE coverage and NR island coverage mode. Moreover, a large amount of LTE is deployed below 6GHz, and there is very little spectrum below 6GHz that can be used for 5G. Therefore, NR must study the spectrum application above 6GHz, and the high frequency band has limited coverage and fast signal fading. At the same time, in order to protect mobile operators' early investment in LTE, a tight interworking mode between LTE and NR is proposed.
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,In order to reduce air interface signaling, quickly restore wireless connections, and quickly restore data services, 5G defines a new radio resource control (Radio Resource Control, RRC) state, that is, the RRC inactive (RRC_INACTIVE) state. This state is different from the RRC idle (RRC_IDLE) state and the RRC active (RRC_ACTIVE) state. among them,
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。1) RRC_IDLE state (abbreviated as idle state): mobility is UE-based cell selection and reselection, paging is initiated by the Core Network (Core Network, CN), and the paging area is configured by the CN. There is no UE context and no RRC connection on the base station side.
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。2) RRC_CONNECTED state (referred to as connected state for short): There is an RRC connection, and UE context exists on the base station side and the UE side. The network side knows that the location of the UE is of a specific cell level. Mobility is the mobility controlled by the network side. Unicast data can be transmitted between the UE and the base station.
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。3) RRC_INACTIVE state (referred to as inactive state for short): Mobility is UE-based cell selection and reselection, there is a connection between CN-NR, UE context is stored on a certain base station, and paging is triggered by RAN, based on The paging area of the RAN is managed by the RAN, and the network side knows that the location of the UE is based on the paging area level of the RAN.
NR将来会部署在高频上,为了提高覆盖,在5G中,通过引入beam sweeping的机制来满足覆盖的需求(用空间换覆盖,用时间换空间),如图2所示。在引入beam sweeping后,每个波束方向上都需要发送同步信号,5G的同步信号以同步信号块(SS/PBCH block,SSB)的形式给出,包含主同步信号(Primary Synchronisation Signal,PSS)、辅同步信号(Secondary Synchronisation Signal,SSS)、和物理广播信道(Physical Broadcast Channel,PBCH),如图3所示。5G的同步信号以同步信号突发组(SS burst set)的形式在时域上周期性出现,如图4所示。NR will be deployed at high frequencies in the future. In order to improve coverage, in 5G, a beam sweeping mechanism is introduced to meet the coverage requirements (using space for coverage and time for space), as shown in Figure 2. After the introduction of beam sweeping, synchronization signals need to be sent in each beam direction. 5G synchronization signals are given in the form of synchronization signal blocks (SS/PBCH block, SSB), including primary synchronization signals (Primary Synchronization Signal, PSS), The secondary synchronization signal (Secondary Synchronization Signal, SSS) and the physical broadcast channel (Physical Broadcast Channel, PBCH) are shown in Figure 3. The 5G synchronization signal periodically appears in the time domain in the form of a synchronization signal burst set (SS burst), as shown in Figure 4.
每个小区的实际传输的beam个数通过网络侧配置来确定,但是小区所在的频点决定了可以配置最多的beam个数,如下表1所示。The actual number of beams transmitted in each cell is determined by the network side configuration, but the frequency point where the cell is located determines the maximum number of beams that can be configured, as shown in Table 1 below.
频率范围Frequency Range | L(最多的beam个数)L (the maximum number of beams) |
up to 3(2.4)GHzup to 3(2.4) |
44 |
3(2.4)GHz—6GHz3(2.4)GHz-6GHz | 88 |
6GHz—52.6GHz6GHz—52.6GHz | 6464 |
表1Table 1
5G中的最大信道带宽可以是400MHz(即宽带),相比于LTE中的最大信道带宽20MHz来说,5G中的最大信道带宽很大。如果UE保持工作在宽带载波(即最大信道带宽)上,则UE的功率消耗是很大的。所以建议UE的射频带宽可以根据UE实际的吞吐量来调整,为此引入了BWP的概念,引入BWP的动机是优化UE的功率消耗。例如UE的速率要求很低,可以给UE配置小一点的带宽(即带宽较小的BWP),如果UE的速率要求很高,则可以给UE配置大一点的带宽(即带宽较大的BWP)。如果UE支持高速率,或者操作在载波聚合(Carrier aggregation,CA)模式下,则可以给UE配置多个BWP。此外,BWP的另一个目的就是触发一个小区中多个参数集(numerology)的共存,如BWP1对应numerology1,BWP2对应numerology2。The maximum channel bandwidth in 5G can be 400MHz (ie, broadband). Compared with the maximum channel bandwidth of 20MHz in LTE, the maximum channel bandwidth in 5G is very large. If the UE keeps working on a broadband carrier (that is, the maximum channel bandwidth), the power consumption of the UE is very large. Therefore, it is recommended that the radio frequency bandwidth of the UE can be adjusted according to the actual throughput of the UE. For this reason, the concept of BWP is introduced. The motivation for introducing BWP is to optimize the power consumption of the UE. For example, the rate requirement of the UE is very low. You can configure the UE with a smaller bandwidth (that is, a BWP with a smaller bandwidth). If the UE has a high rate requirement, you can configure the UE with a larger bandwidth (that is, a BWP with a larger bandwidth). . If the UE supports a high rate or operates in a carrier aggregation (CA) mode, multiple BWPs can be configured for the UE. In addition, another purpose of BWP is to trigger the coexistence of multiple parameter sets (numerology) in a cell, for example, BWP1 corresponds to numerology1, and BWP2 corresponds to numerology2.
空闲态或者非激活态的UE驻留在初始BWP(initial BWP)上,初始BWP对于空闲态或者非激活态的UE是可见的,UE可以在初始BWP上获取主信息块(Master Information Block,MIB)、剩余最小系统信息(Remaining Minimum system Information,RMSI)、其他系统信息(Other System Information,OSI)以及寻呼(paging)等信息。An idle or inactive UE camps on the initial BWP (initial BWP). The initial BWP is visible to the idle or inactive UE. The UE can obtain the Master Information Block (MIB) on the initial BWP. ), remaining minimum system information (Remaining Minimum system Information, RMSI), other system information (Other System Information, OSI), and paging (paging) information.
3GPP版本6(Release 6,R6)中引入了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。MBMS was introduced in 3GPP Release 6 (Release 6, R6). MBMS is a technology that transmits data from one data source to multiple UEs by sharing network resources. This technology can effectively utilize network resources while providing multimedia services. Realize the broadcast and multicast of multimedia services at a higher rate (such as 256kbps).
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。Due to the low spectrum efficiency of MBMS in 3GPP R6, it is not sufficient to effectively carry and support the operation of mobile TV-type services. Therefore, in LTE, 3GPP clearly proposed to enhance the ability to support downlink high-speed MBMS services, and determined the design requirements for the physical layer and air interface.
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。3GPP R9 introduced evolved MBMS (evolved MBMS, eMBMS) into LTE. eMBMS proposes the concept of single frequency network (Single Frequency Network, SFN), namely Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN), MBSFN uses a unified frequency to send service data in all cells at the same time, but To ensure synchronization between the cells. This method can greatly improve the overall signal-to-noise ratio distribution of the cell, and the spectrum efficiency will be greatly improved accordingly. eMBMS realizes the broadcast and multicast of services based on the IP multicast protocol.
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。In LTE or enhanced LTE (LTE-Advanced, LTE-A), MBMS has only a broadcast bearer mode, and no multicast bearer mode. In addition, the reception of MBMS services is suitable for UEs in idle state or connected state.
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。3GPP R13 introduced the single cell point to multipoint (Single Cell Point To Multiploint, SC-PTM) concept, and SC-PTM is based on the MBMS network architecture.
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 introduces new logical channels, including Single Cell-Multicast Control Channel (SC-MCCH) and Single Cell-Multicast Transport Channel (SC-MTCH). SC-MCCH and SC-MTCH are mapped to downlink shared channel (Downlink-Shared Channel, DL-SCH), and further, DL-SCH is mapped to physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), where SC -MCCH and SC-MTCH belong to logical channels, DL-SCH belongs to transport channels, and PDSCH belongs to physical channels. SC-MCCH and SC-MTCH do not support Hybrid Automatic Repeat reQuest (HARQ) operations.
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。MBMS introduces a new type of System Information Block (SIB), namely SIB20. Specifically, the SC-MCCH configuration information is transmitted through SIB20, and there is only one SC-MCCH in a cell. The configuration information of the SC-MCCH includes: the modification period of the SC-MCCH, the repetition period of the SC-MCCH, and information such as radio frames and subframes for scheduling the SC-MCCH. Further, 1) the boundary of the SC-MCCH modification period satisfies SFN mod m=0, where SFN represents the system frame number of the boundary, and m is the modification period of the SC-MCCH configured in the SIB20 (ie, sc-mcch-ModificationPeriod). 2) The radio frame scheduling SC-MCCH satisfies: SFN mod mcch-RepetitionPeriod=mcch-Offset, where SFN represents the system frame number of the radio frame, mcch-RepetitionPeriod represents the repetition period of SC-MCCH, and mcch-Offset represents SC-MCCH The offset. 3) The subframe for scheduling SC-MCCH is indicated by sc-mcch-Subframe.
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。The SC-MCCH is scheduled through the Physical Downlink Control Channel (PDCCH). On the one hand, a new radio network temporary identity (Radio Network Tempory Identity, RNTI), namely single cell RNTI (Single Cell RNTI, SC-RNTI) is introduced to identify the PDCCH (such as SC-MCCH PDCCH) used to schedule SC-MCCH, Optionally, the fixed value of SC-RNTI is FFFC. On the other hand, a new RNTI is introduced, namely Single Cell Notification RNTI (SC-N-RNTI) to identify the PDCCH used to indicate the change notification of the SC-MCCH (such as the notification PDCCH). Optionally, the SC -N-RNTI has a fixed value of FFFB; further, one of the 8 bits (bits) of DCI 1C can be used to indicate the change notification. In LTE, the configuration information of the SC-PTM is based on the SC-MCCH configured by the SIB20, and then the SC-MCCH is configured with the SC-MTCH, and the SC-MTCH is used to transmit service data.
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。Specifically, the SC-MCCH only transmits one message (that is, SCPTMConfiguration), which is used to configure the configuration information of the SC-PTM. The configuration information of SC-PTM includes: Temporary Mobile Group Identity (TMGI), session identifier (seession id), group RNTI (Group RNTI, G-RNTI), discontinuous reception (Discontinuous Reception, DRX) configuration information And the SC-PTM business information of the neighboring cell, etc. It should be noted that the SC-PTM in R13 does not support Robust Header Compression (ROHC) function.
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。The downlink discontinuous reception of SC-PTM is controlled by the following parameters: onDurationTimerSCPTM, drx-InactivityTimerSCPTM, SC-MTCH-SchedulingCycle, and SC-MTCH-SchedulingOffset.
当满足[(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset时,启动定时器onDurationTimerSCPTM;When [(SFN*10)+subframe number]modulo(SC-MTCH-SchedulingCycle)=SC-MTCH-SchedulingOffset is satisfied, start the timer onDurationTimerSCPTM;
当接收到下行PDCCH调度时,启动定时器drx-InactivityTimerSCPTM;When receiving the downlink PDCCH scheduling, start the timer drx-InactivityTimerSCPTM;
只有当定时器onDurationTimerSCPTM或drx-InactivityTimerSCPTM运行时才接收下行SC-PTM业务。Only when the timer onDurationTimerSCPTM or drx-InactivityTimerSCPTM is running, the downlink SC-PTM service is received.
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。SC-PTM service continuity adopts the concept of MBMS service continuity based on SIB15, namely "SIB15+MBMSInterestIndication" mode. The service continuity of the idle UE is based on the concept of frequency priority.
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,然而,由于MBMS业务的传输不能根据具体某个终端设备的信道环境而改变传输的调度信息来实现数据传输的可靠性,例如改变TB size或者MCS等。所以小区边缘对于MBMS业务来说,性能一般比较差。如果实现小区之间的传输的内容同步,即相邻小区在同一个时频资资源发送相同的数据,使得终端设备在小区边缘可以同时接收来自两个小区的同一个数据,从而通过合并增益提高数据传输的可靠性,可是如何做到相邻小区之间的内容同步传输需要明确。为此,提出了本申请实施例的以下技术方案。In NR, many scenarios need to support the service requirements of multicast and broadcast, such as the Internet of Vehicles and the Industrial Internet. Therefore, it is necessary to introduce MBMS into NR. However, the transmission of MBMS services cannot change the transmission scheduling information according to the channel environment of a specific terminal device to achieve the reliability of data transmission, such as changing the TB size or MCS. Therefore, the cell edge generally has poor performance for MBMS services. If the content of transmission between cells is synchronized, that is, neighboring cells send the same data in the same time-frequency resource, so that the terminal device can receive the same data from the two cells at the cell edge at the same time, thereby increasing the gain by combining The reliability of data transmission, but how to achieve synchronous transmission of content between neighboring cells needs to be clear. To this end, the following technical solutions of the embodiments of the present application are proposed.
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5,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)。In the technical solution of the embodiment of the present application, a new SIB (called the first SIB) is defined. Referring to FIG. 5, the first SIB includes the configuration information of the first MCCH. Here, the first MCCH is the control channel of the MBMS service. In other words, the first SIB is used to configure the configuration information of the control channel of NR MBMS. Optionally, the control channel of NR MBMS may also be called NR MCCH (that is, the first 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)。Further, the first MCCH is used to carry the first signaling. The embodiment of the present application does not limit the name of the first signaling. For example, the first signaling is signaling A, and the first signaling includes at least one first MTCH. Here, the first MTCH is a service channel of the MBMS service (also referred to as a data channel or transmission channel), and the first MTCH is used to transmit MBMS service data (such as NR MBMS service data). In other words, the first MCCH is used to configure the configuration information of the NR MBMS traffic channel. Optionally, the NR MBMS traffic channel may also be called NR MTCH (that is, the first 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。Specifically, the first signaling is used to configure a NR MBMS service channel, service information corresponding to the service channel, and scheduling information corresponding to the service channel.
