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。

RRC状态
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。
Figure PCTCN2019106471-appb-000002
MBMS
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。
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。如何配置NR中的MBMS配置信息以实现并优化MBMS业务需要明确。另一方面,在LTE中,MBMS配置信息的实现是通过SIB20配置SC-MCCH,然后通过SC-MCCH配置SC-MTCH;而SC-MCCH的传输是基于小区级别的,在UE小区变更后需要重新获取MBMS配置信息,引入了由于小区变更导致的业务中断或业务时延。再者,NR中的SIB是基于UE请求发送的,所以在小区变更后会进一步引入业务中断或业务时延。为此,提出了本申请实施例的以下技术方案。
图2为本申请实施例提供的信息配置方法的流程示意图,如图2所示,所述信息配置方法包括以下步骤:
步骤201:终端设备接收第一SIB,所述第一SIB包括第一MCCH的配置信息,所述第一MCCH用于承载第一信令,所述第一信令用于确定至少一个第一MTCH的配置信息。
本申请实施例中,网络设备发送第一SIB,终端设备接收第一SIB。可选地,所述网络设备可以是基站,例如gNB。
本申请实施例中,定义一个新的SIB(称为第一SIB),参照图3,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,参照图4,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5,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。
通过本申请实施例的上述技术方案,明确了NR中的MBMS配置信息(即第一SIB、第一MCCH的配置信息、第一MTCH的配置信息),从而实现NR系统支持MBMS业务的广播和组播。进一步,为了实现小区变更前后终端设备如何获取MBMS配置信息,以达到提高业务连续性以及缩短业务中断时延或者业务数据丢失的目的,提出了以下方案,需要说明的是,本申请实施例中涉及到的小区变更是指小区重选或小区切换。需要说明的是,本申请实施例中的第一SIB、第一MCCH、第一信令以及第一MTCH属于第一小区侧的相关概念,第二SIB、第二MCCH、第二信令以及第二MTCH属于第二小区侧的相关概念。其中,“第一”和“第二”是为了区分两个不同小区,其概念是类似的。

方案一
考虑到终端设备在一个小区接收MBMS业务,当发生小区变更时,为了业务连续性以及缩短业务中断或者业务时延或者避免业务数据丢失。可以配置第一SIB采用如下任意一种发送形式:
(1)所述第一SIB持续被发送,具体地,所述第一SIB由第一小区持续发送给所述终端设备。
这里,第一小区为终端设备当前驻留的小区,具体地,第一小区不基于UE请求而持续(或者说一直)发送第一SIB。终端设备驻留到第一小区后,终端设备可以避免发送用于请求第一SIB的请求消息,而直接获得第一小区发送的第一SIB,保障了业务连续性以及缩短业务中断或者业务时延或者避免业务数据丢失。
(2)所述第一SIB的类型为区域专用SIB,所述第一SIB关联第一区域标识,所述第一区域标识用于标识所述第一SIB的有效区域范围。
所述终端设备接收第一小区发送的第一SIB;所述终端设备从所述第一小区变更到第二小区后,获取所述第二小区侧的第一区域标识;若所述第二小区侧的第一区域标识和所述第一小区侧的第一区域标识相同,则所述终端设备使用已获取的所述第一小区的第一SIB来确定所述第一MCCH的配置信息,并基于所述第一MCCH的配置信息接收MBMS业务。
具体地,定义第一SIB为区域专用(area specific)类型的SIB。可选地,可以在SIB1中配置第一SIB为area specific类型的SIB,且配置第一SIB关联的第一区域标识,所述第一区域标识用于标识所述第一SIB的有效区域范围。进一步,第一区域标识可以是NR系统中支持的系统信息区域标识(systemInformationAreaID)或者新定义的区域标识。应理解,第一区域标识也可以用于标识一个MBMS业务区域,MBMS配置信息(即第一SIB)在该MBMS业务区域内保持不变,可见,终端设备在该MBMS业务区域内发生小区变更时,不用重新获取MBMS配置信息,使用之前的MBMS配置信息即可。
(3)所述第一SIB还包括第二MCCH的配置信息,所述第二MCCH用于承载第二信令,所述第二信令用于确定至少一个第二MTCH的配置信息;所述第一MCCH的配置信息对应第一小区,所述第二MCCH的配置信息对应第二小区,所述第二小区为所述第一小区的邻区。
所述终端设备接收第一小区发送的第一SIB;所述终端设备从所述第一小区变更到第二小区后,使用已获取的所述第一小区的第一SIB来确定所述第二MCCH的配置信息,并基于所述第二MCCH的配置信息接收MBMS业务。
具体地,对于终端设备所在的第一小区,第一小区不仅广播本小区的MCCH的配置信息(即所述第一MCCH的配置信息),还广播邻区的MCCH的配置信息(即所述第二MCCH的配置信息),即第一SIB中承载的内容包括第一小区对应的第一MCCH的配置信息,以及第二小区对应的第二MCCH的配置信息。终端设备在小区变更后,不需要重新读取第二小区的第一SIB中的内容。
需要说明的是,上述(1)、(2)和(3)中的方案可以单独来实施,也可以将上述方案进行任意结合来实施。
Figure PCTCN2019106471-appb-000004
方案二
由于第一SIB是通过PDCCH调度发送的,为了使终端设备能够尽快获取第一SIB的内容,以缩短业务中断或者业务时延或者避免业务数据丢失,提出以下方案。
(1)所述第一SIB关联独立的第一公共搜索空间,所述第一公共搜索空间用于传输第一PDCCH,所述第一PDCCH用于调度所述第一SIB。
具体地,可以为第一SIB配置独立的公共搜索空间(即所述第一公共搜索空间),可选地,该独立的第一公共搜索空间具有短的周期。该独立的第一公共搜索空间,可以在SIB1中配置或者在MIB中配置。
(2)所述第一SIB关联RMSI的第二公共搜索空间,所述第二公共搜索空间用于传输第一PDCCH和第二PDCCH,所述第一PDCCH用于调度所述第一SIB,所述第二PDCCH用于调度RMSI;所述第一PDCCH携带第一指示信息,所述第一指示信息用于指示所述第一PDCCH调度的数据为所述第一SIB,所述第二PDCCH携带第二指示信息,所述第二指示信息用于指示所述第二PDCCH调度的数据为所述RMSI。
具体地,定义第一SIB使用RMSI的公共搜索空间(即所述第二公共搜索空间)。这种情况下,为了区分第一SIB和RMSI,在用于调度第一SIB的第一PDCCH里面添加第一指示信息,通过该第一指示信息指示第一PDCCH调度的数据为所述第一SIB; 同理,在用于调度RMSI的第二PDCCH里面添加第二指示信息,通过该第二指示信息指示第二PDCCH调度的数据为所述RMSI。
需要说明的是,第一指示信息和第二指示信息可以统称为指示信息,该指示信息用于指示PDCCH调度的数据是RMSI,还是第一SIB,还是OSI。
(3)所述第一SIB关联独立的第一SI-RNTI,所述第一SI-RNTI用于加扰第一PDCCH,所述第一PDCCH用于调度所述第一SIB。
具体地,为第一SIB配置独立的SI-RNTI(即所述第一SI-RNTI),所述第一SI-RNTI可以用M-SI-RNTI来表示,M-SI-RNTI不同于现有系统定义的全网唯一的SI-RNTI,通过M-SI-RNTI来加扰用于调度第一SIB的第一PDCCH。
需要说明的是,上述(1)、(2)和(3)中的方案可以单独来实施,也可以将上述(3)中的方案可以与上述(1)或(2)中的方案进行任意结合来实施。
Figure PCTCN2019106471-appb-000005
方案三
所述第一MCCH通过第三PDCCH调度,所述第三PDCCH通过SC-RNTI或者M-RNTI加扰。这里,第一MCCH的传输是基于PDCCH(即所述第三PDCCH)调度的,该PDCCH采用的RNTI是全网唯一分配的RNTI,可以用SC-RNTI或者M-RNTI来表示。
本实施例中,定义第一MCCH中承载的第一信令在一个区域范围内有效,具体地,所述第一MCCH关联第二区域标识,所述第二区域标识用于确定所述第一MCCH中承载的所述第一信令的有效区域范围。
可选地,所述第二区域标识为新定义标识,所述新定义标识通过所述第一SIB或者第二SIB进行配置;或者,所述第二区域标识为系统广播区域标识。这里,第二SIB例如是SIB1。系统广播区域标识例如是NR中的systemInformationAreaID。
所述终端设备接收第一小区发送的第一SIB;所述终端设备从所述第一小区变更到第二小区后,获取所述第二小区侧的第二区域标识;若所述第二小区侧的第二区域标识和所述第一小区侧的第二区域标识相同,则所述终端设备使用已获取的所述第一小区的所述第一MCCH中的第一信令来确定至少一个第一MTCH的配置信息,并基于所述至少一个第一MTCH的配置信息接收MBMS业务。
举个例子:当终端设备从发生小区变更后,首先获取第二小区的第二区域标识(如systemInformationAreaID),如果与第一小区的第二区域标识相同,则终端设备不需要重新获取第一MCCH中的第一信令的内容,否则需要重新获取,然后才能接收MBMS业务。
Figure PCTCN2019106471-appb-000006
方案四
所述第一SIB还包括至少一个第二MTCH的配置信息;所述第一MTCH的配置信息对应第一小区,所述第二MTCH的配置信息对应第二小区,所述第二小区为所述第一小区的邻区。
所述终端设备接收第一小区发送的第一SIB;所述终端设备从所述第一小区变更到第二小区后,使用已获取的所述第一小区的第一SIB来确定所述至少一个第二MTCH的配置信息,并基于所述至少一个第二MTCH的配置信息接收MBMS业务。
举个例子:对于终端设备所在的第一小区,第一小区不仅广播本小区的MCCH的配置信息(即所述第一MCCH的配置信息),还广播邻区(即所述第二小区)的MTCH的配置信息(即所述第二MTCH的配置信息),当终端设备发生小区变更后,不需要重新读取第二小区的第二MCCH中承载的内容。
