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.

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.

Abstract

Description

一种资源指示方法及装置、通信设备 技术领域
本申请实施例涉及移动通信技术领域,具体涉及一种资源指示方法及装置、通信设备。
背景技术
多媒体广播多播服务(Multimedia Broadcast Multicast Service,MBMS)是一种通过共享网络资源从一个数据源向多个用户传送数据的技术,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。
在新无线(New Radio,NR)系统中,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。小区边缘对于MBMS业务来说,性能一般比较差,所以如果实现小区之间的传输的内容同步,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,可是如何做到两个相邻小区之间的内容同步传输是一个问题。

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。
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。

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。

波束扫描(beam sweeping)
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。
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。
频率范围 L(最多的beam个数)
up to 3(2.4)GHz 4
3(2.4)GHz—6GHz 8
6GHz—52.6GHz 64

带宽部分(BWP)
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。
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。

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,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。
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)。
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6,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 1 PDCCH、MTCH 2 PDCCH、…、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7,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。
本申请实施例的技术方案中,网络设备通过系统广播消息或者MCCH预配置传输MBMS业务的无线资源(如configured grant或者pre-configured Grant)。这里,系统广播消息例如是上述方案中的第一SIB,MCCH例如是上述方案中的第一MCCH。
这里,网络侧是CU和DU分离架构,可以看做所述网络设备包括CU和至少一个DU,这种情况,预配置的无线资源由所述CU发送给所述至少一个DU。需要说明的是,对于多个DU的情况,CU发送给多个DU的预配置的无线资源是相同的。
参照图8,预配置的无线资源(如configured grant或者pre-configured Grant)通过F1接口由gNB CU发送给gNB DU。这里,F1接口为gNB CU和gNB DU之间的接口。
本申请实施例中,为MBMS业务预配置的无线资源在一定时间范围和/或频谱范围周期分布,且按照一定规则进行MBMS无线资源的编号(即MBMS无线资源的索引)。需要说明的是,MBMS无线资源也可以称为MBMS时机(MBMS occasion),一个MBMS occasion可以包含几个符号或者几个时隙。
在CU和DC分离架构中,SDAP层和PDCP层在CU侧,只有RLC层、MAC层和PHY层(即L2协议栈)在DU侧。如图8所示,对于下行来说,CU收到来自核心网的MBMS业务数据,对该MBMS业务数据进行封装,将携带MBMS业务数据的PDCP PDU发送给DU,DU对PDCP PDU进行处理后发送出去。不同的DU可以覆盖不同的小区,一般,属于同一CU的多个DU覆盖的小区是相邻小区。相邻小区之间的内容同步可以采用DU向其关联的至少一个CU发送资源指示信息(即第一指示信息)来实现,以下具体说明。
图9为本申请实施例提供的资源指示方法的流程示意图,如图9所示,所述资源指示方法包括以下步骤:
步骤901:CU向至少一个DU发送第一指示信息,DU接收CU发送的第一指示信息,所述第一指示信息用于指示MBMS业务数据的无线资源位置。
本申请实施例中,网络侧采用CU和DU分离架构,其中,CU和DU都属于基站 侧的实体,一个CU可以关联一个或多个DU。其中,CU负责的协议栈包括:SDAP层和PDCP层。DU负责的协议栈包括:RLC层、MAC层以及PHY层。
在一可选实施方式中,基站为gNB,相应地,CU也可以称为gNB CU,DU也可以称为gNB DU。如图8所示,gNB CU与核心网侧之间通过GTP隧道传输MBMS业务数据。gNB CU与gNB DU1以及gNB DU2之间也是通过GTP隧道传输MBMS业务数据。DU1和DU2发送MBMS业务数据,从而终端设备可以接收到MBMS业务数据。
需要说明的是,不同的DU可以覆盖不同的小区,一般,属于同一CU的多个DU覆盖的小区是相邻小区。多个CU基于第一指示信息,在相同的无线资源位置发送同一MBMS业务数据,从而实现小区之间的内容同步。第一指示信息的具体实现,可以采用以下方式。
