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(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。

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)。

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5G中,最大的信道带宽可以是400MHZ(wideband carrier),相比于LTE最大20M带宽来说,带宽很大。如果UE保持工作在宽带载波上,则增加了UE的功率消耗。通过带宽分量(BandWidth Part,BWP)可以优化UE的功率消耗。即UE的RF带宽可以根据UE实际的吞吐量来调整。BWP的另一个目的就是触发一个小区中多个空口参数集(Numerology)共存。idle状态或者inactive状态的UE驻留在initial BWP上,这个BWP对于idle状态或者inactive状态UE是可见的,在这个BWP里面可以获取MIB,RMSI,OSI已经paging等信息。
图4至图6是本申请实施例的终端设备的BWP的示意性框图。
例如,如图4所示,若UE的速率较低,可以给UE配置载波带宽的部分带宽,例如BWP1。再如,如图5所示,如果UE对速率的要求较高,可以给UE配置大一点的BWP。例如比BWP1大的BWP2。再如,如图6所示,如果UE支持高速率或者工作在CA模式下,可以给配置多个BWP,例如BWP1和BWP2。可选的,BWP1和BWP2可以分别对应空口参数集1和空口参数集2。
可以通过RRC专用信令可以给一个UE配置最多4个UL BWP和最多4个DL BWP,但同一时刻只能有一个DL BWP和UL BWP被激活。在RRC专用信令,可以指示所配置的BWP中第一个激活的BWP。同时在UE处于连接态过程中,也可以通过DCI在不同的BWP之间切换。当处于非激活状态的载波,进入激活状态后,第一个激活的BWP为RRC中配置的第一个激活的BWP。每个BWP的配置参数包括以下中的至少一项:
子载波间隔(subcarrierSpacing);
循环前缀(cyclicPrefix);
BWP的第一个PRB以及连续的PRB个数(locationAndBandwidth)。
BWP标识(bwp-Id);以及
BWP公共配置参数(bwp-Common)和专用配置参数(bwp-Dedicated)。
示例性地,BWP id在RRC信令中取值可以为0到4,0默认为初始BWP。
在DCI中BWP indicator为2bit。如果配置的BWP个数小于等于3个,则BWP indicator可以为1,2或3,BWP indicator 1,2以及3分别对应BWP id 1,2以及3。如果BWP的个数为4个,则BWP indicator可以为0,1,2以及3,可选的,BWP indicator 0,1,2以及3分别对应按照顺序索引配置的BWP。可选的,在配置BWP的时候使用连续的BWP id。
为便于对本申请方案的理解,下面对NR单播通信中PUCCH资源进行说明。
LTE系统在未引入载波聚合之前,传输动态调度PDSCH对应的ACK/NACK信息的PUCCH格式1a/1b的资源根据调度PDSCH传输的DCI占用的CCE计算得到。引入载波聚合之后,传输动态调度PDSCH对应的ACK/NACK信息的PUCCH格式3/4/5的资源则采用了半静态配置加DCI动态指示的方式。NR中沿用了LTE的工作机制指示传输ACK/NACK信息的PUCCH,即首先由高层信令配置PUCCH资源集,然后DCI指示资源集中的一个PUCCH。
图7是本申请实施例提供的PUCCH资源集配置示意图。
如图7所示,NR中最多可以配置4个PUCCH资源集合(即集合0至集合3),每个资源集合承载的UCI比特数量范围不同。例如,集合0承载的UCI比特数量范围为0~2,集合1承载的UCI比特数量范围为3~N2,集合2承载的UCI比特数量范围为N2~N3,集合3承载的UCI比特数量范围为N3~1706。每个集合中可以包括相同或不同的PUCCH格式。终端设备根据待传输的UCI比特数量从最多4个资源集合中确定一个资源集合。然后,根据DCI的指示从该集合中确定一个PUCCH资源。当然,图7中的数字仅为本申请的示例,不应理解为对本申请的限制。
另外,在实际系统中大量的UE需要同时反馈1或2比特的ACK/NACK信息,若DCI中PUCCH 指示信息域为2比特,即每个终端设备只能有4个备选的PUCCH资源传输1或2比特ACK/NACK,则系统中资源冲突问题会比较严重。所以,在NR DCI中使用3比特指示PUCCH资源。对于PUCCH集合0(承载1~2比特UCI),高层信令可配置最多32个PUCCH资源。当PUCCH资源数量不大于8时,直接根据DCI中的指示确定PUCCH资源。当PUCCH资源数量大于8时,则根据CCE索引和DCI中的3比特指示信息确定一个PUCCH资源,具体方法为:
其中,r
PUCCH为PUCCH资源索引号,N
CCE,p为CORESET中CCE的数量,n
CCE,p为DCI占用的第一个CCE的索引号,R
PUCCH为PUCCH资源总数,Δ
PRI为DCI中3比特指示信息所指示的值。
对于PUCCH集合1、2、3(承载2比特以上UCI),高层信令可配置最多8个PUCCH资源。终端设备根据DCI中的3比特指示信息确定使用的PUCCH资源,而不使用隐式资源确定方法。
NR中用于单播通信的PUCCH资源可通过RRC信令中的如表1所示的参数配置。
表1
如表1所示,PUCCH-ResourceSet用于配置PUCCH资源集合,一个PUCCH资源集合内包含一个或多个PUCCH资源,一个或多个PUCCH资源由pucch-ResourceSetId配置,maxPayloadSize用于配置当前PUCCH资源集合内允许的最大比特个数。上述pucch-ResourceSetId关联到一个PUCCH资源配置PUCCH-Resource,每个PUCCH资源配置中,startingPRB用于指示当前PUCCH资源的起始PRB,intraSlotFrequencyHopping用于指示当前PUCCH资源是否激活时隙内跳频,format用于配置当前PUCCH资源内支持的PUCCH格式。
如果一个PUCCH资源支持的PUCCH格式为PUCCH格式0(PUCCH Format 0),则RRC层信令还可以用于配置PUCCH格式0的如表2所示的信息。
表2
如表2所示,如果一个PUCCH资源支持的PUCCH格式为PUCCH格式0,则RRC层信令中包含以下参数用于配置PUCCH格式0的初始循环移位(initialCyclicShift),符号个数(nrofSymbols),和起始符号(startingSymbolIndex)。PUCCH格式0为在频域占用一个PRB,在时域占用一个或2个符号。
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 MBS中的组播广播业务引入了反馈机制。
具体的,针对NR MBS系统,提出了两种备选HARQ-ACK反馈方式,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。第一种为仅反馈NACK的方式,网络发送MBS数据,在接收该MBS数据的所有终端设备中,正确接收该数据的终端设备不发送反馈信息,没有正确接收该数据的终端设备向网络发送NACK信息,在这种方式中,多个接受该MBS数据的终端设备可以通过共享的上行资源发送包含NACK的HARQ反馈信息。第二种为即反馈ACK又反馈NACK的方式,当UE成功接收基站发送的MBS数据时,反馈ACK,否则反馈NACK。为便于说明,本文中将第一种反馈方式,即仅反馈MACK的方式定义为第一反馈方式。
基于此,如果支持第一反馈方式,反馈信息应通过什么样的物理信道承载,以及如果反馈多个信息比特等问题是本申请需要进一步解决的技术问题。
图8示出了根据本申请实施例的无线通信方法200的示意性流程图,所述方法200可以由终端设备执行。例如如图1所示的终端设备。
如图8所示,所述方法200可包括:
S210,终端设备确定第一群组无线网络临时标识G-RNTI对应的HARQ反馈信息;所述第一G-RNTI关联有用于第一反馈方式的一个或多个物理上行控制信道PUCCH资源,所述第一反馈方式包括仅反馈包含非确认NACK的HARQ反馈信息的混合自动重传请求HARQ反馈方式;
S220,所述终端设备在所述一个或多个PUCCH资源中的一个PUCCH资源上,发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息;所述第一G-RNTI对应的HARQ反馈信息包括所述第一G-RNTI对应的包含NACK的HARQ反馈信息。
例如,所述终端设备在所述一个或多个PUCCH资源所在的时隙内,在所述一个或多个PUCCH资源中的一个PUCCH资源上,发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息。
基于以上技术方案,通过所述第一G-RNTI关联用于第一反馈方式的一个或多个PUCCH资源,能够使得所述终端设备能够在所述一个或多个PUCCH资源中的一个PUCCH资源上,发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息,由此,能够针对组播或广播进行反馈,使得网络可以根据反馈确定是否需要发送重传数据,进而能够确保业务传输可靠性。
需要说明的是,本申请实施例中,所述一个或多个PUCCH资源可以通过高层信令配置。可选的,所述一个或多个PUCCH资源可以是共享资源,以提升资源利用率。但本申请实施例对所述一个或多个PUCCH资源的具体实现形式不作限定。下面结合具体实施例对所述一个或多个PUCCH资源进行说明。
实施例1-1:
本实施例中,所述一个或多个PUCCH资源可以是一个PUCCH资源。
换言之,终端设备配置有一个或多个用于第一反馈方式的PUCCH资源,每个PUCCH资源分别对应不同的G-RNTI。
在本实施例中,终端设备确定用于第一反馈方式的PUCCH资源,每一个用于第一反馈方式的PUCCH资源与一个G-RNTI关联,即,配置所述用于第一反馈方式的PUCCH资源的RRC层信令中应指示该PUCCH资源关联的G-RNTI的值,或与之关联的G-RNTI的索引。其中,G-RNTI至少用于加扰调度承载MBS传输的PDSCH的PDCCH。在本实施例中,如果终端设备配置有多个G-RNTI,则对于其中的任何一个G-RNTI,均可以配置有与之对应的用于第一反馈方式的一个PUCCH资源,较优的,终端设备配置的一个或多个用于第一反馈方式的PUCCH资源属于同一个PUCCH资源集合。
图9是本申请实施例提供的PUCCH资源和G-RNTI的关联关系的示意图。
如图9所示,PUCCH资源#0~PUCCH资源#U-1,分别关联至G-RNTI#0~G-RNTI#M-1。
在本实施例中,如果用于第一反馈方式的PUCCH资源支持的PUCCH格式为PUCCH格式0,则RRC层信令中还可以包含用于配置PUCCH格式0的以下参数:初始循环移位(initialCyclicShift),符号个数(nrofSymbols)以及起始符号(startingSymbolIndex)。PUCCH格式0在频域占用一个PRB, 在时域占用一个或2个符号。
实施例1-2:
本实施例中,所述一个或多个PUCCH资源可以是一个PUCCH资源集合。
换言之,终端设备配置有一个或多个用于第一反馈方式的PUCCH资源集合,每个PUCCH资源集合分别对应不同的G-RNTI。
在本实施例中,终端设备确定用于第一反馈方式的PUCCH资源集合,每一个用于第一反馈方式的PUCCH资源集合与一个G-RNTI关联,即配置所述用于第一反馈方式的PUCCH资源集合的RRC层信令中应指示该PUCCH资源集合关联的G-RNTI的值,或与之关联的G-RNTI的索引,其中,所述G-RNTI至少用于加扰调度承载MBS传输的PDSCH的PDCCH。每个用于第一反馈方式的PUCCH资源集合内包含一个或多个用于第一反馈方式的PUCCH资源。在本实施例中,如果终端设备配置有多个G-RNTI,则对于其中的任何一个G-RNTI,均可以配置有与之对应的用于第一反馈方式的PUCCH资源集合。
在一种实现方式中,如果用于第一反馈方式的PUCCH资源集合中的PUCCH资源有多个,每个PUCCH资源的起始PRB由RRC信令配置。
在一种实现方式中,如果每个PUCCH资源支持的PUCCH格式为PUCCH格式0,则各个PUCCH资源上PUCCH格式0的初始循环移位和起始符号索引由RRC信令配置。
图10是本申请实施例提供的PUCCH资源集合和G-RNTI的关联关系的示意图。
如图10所示,PUCCH资源集合#0~PUCCH资源集合#M-1,分别关联至G-RNTI#0~G-RNTI#S-1。其中,PUCCH资源集合#0~PUCCH资源集合#M-1中的每一个PUCCH资源集合分别包括PUCCH资源#0~PUCCH资源#U-1。
综上可知,本申请实施例中,所述第一G-RNTI关联的用于第一反馈方式的一个或多个PUCCH资源可以是所述第一G-RNTI关联的一个PUCCH资源,也可以是所述第一G-RNTI关联的一个PUCCH资源集合。
此外,本申请实施例中,所述第一G-RNTI对应的HARQ反馈信息可以是所述第一G-RNTI加扰的PDCCH调度的PDSCH的HARQ反馈信息,也可以是所述第一G-RNTI加扰的且用于指示SPS释放的PDCCH的HARQ反馈信息(即SPS释放的HARQ反馈信息),本申请实施例对此不作限定。对于PDSCH,如果其中仅承载一个TB,则该PDSCH的HARQ反馈信息为1比特,如果承载2个TB,则该PDSCH的反馈信息为2比特。如果终端设备成功解码某个TB,则该TB对应的HARQ反馈比特为ACK,即比特值为1,反之为0。
在本申请的一些实施例中,所述第一G-RNTI关联有一个PUCCH资源;所述S220可包括:
所述终端设备在所述第一G-RNTI关联的一个PUCCH资源上,发送所述第一G-RNTI对应的1比特包含NACK的HARQ反馈信息。
换言之,本实施例可采用实施例1-1中的用于第一反馈方式的PUCCH资源配置方式,如果终端设备在所述第一G-RNTI关联的一个PUCCH资源所在时隙u,需要反馈所述第一G-RNTI对应的M比特HARQ反馈信息,M≥1,则如果所述M比特HARQ反馈信息中有一个比特为0(即所述M比特HARQ反馈信息中有一个反馈信息为NACK),则终端设备在所述第一G-RNTI对应的用于第一反馈方式的PUCCH资源发送所述第一G-RNTI对应的且反馈信息为NACK的HARQ反馈信息,否则,终端设备不发送任何信息。
当然,所述第一G-RNTI也可关联有多个PUCCH资源,所述终端设备在所述第一G-RNTI关联的多个PUCCH资源上,可发送所述第一G-RNTI对应的多个比特的包含NACK的HARQ反馈信息。本申请实施例对此不作具体限定。
在本申请的一些实施例中,所述终端设备在所述一个或多个PUCCH资源所在时隙内,确定所述第一G-RNTI对应的M比特HARQ反馈信息,M≥1。基于此,所述终端设备在所述一个或多个PUCCH资源中的一个PUCCH资源上,发送所述M比特HARQ反馈信息中的第一G-RNTI对应的包含NACK的HARQ反馈信息。
在本申请的一些实施例中,所述终端设备在所述一个或多个PUCCH资源所在时隙内,确定所述第一G-RNTI对应的M比特HARQ反馈信息,M≥1;所述第一G-RNTI关联有一个PUCCH资源集合;所述S220可包括:
所述终端设备根据所述M比特HARQ反馈信息的比特状态,在所述第一G-RNTI关联的一个PUCCH资源集合中,确定用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PUCCH资源;所述终端设备在所述用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PUCCH资源上,发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息。
换言之,所述终端设备在一个时隙内存在M个针对一个G-RNTI的HARQ反馈信息,不同比特状态下的反馈信息使用不同的PUCCH资源,其中M≥1。例如,所述终端设备在一个时隙内存在2个针对一个G-RNTI的HARQ反馈信息,所述2个针对一个G-RNTI的HARQ反馈信息为00、01或10时,使用的PUCCH资源不同。
也即是说,本实施例采用实施例1-2中的用于第一反馈方式的PUCCH资源配置方式,如果终端设备在所述第一G-RNTI关联的一个PUCCH资源集合所在时隙u内,所述第一G-RNTI对应的M比特HARQ反馈信息,M≥1,则终端设备根据所述M比特HARQ反馈信息的比特状态,从所述第一G-RNTI关联的用于第一反馈方式的PUCCH资源集合中确定使用的PUCCH资源,并在确定的PUCCH资源上发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息。
在本实施例中,PUCCH资源的配置信息中应至少指示PUCCH资源集合中的PUCCH资源的起始PRB,以及,当PUCCH资源用于支持PUCCH格式0时,指示PUCCH格式0的初始循环移位和起始符号。较优的,对于一个用于第一反馈方式的PUCCH资源集合内的任何两个PUCCH资源,所述两个PUCCH资源的起始PRB,PUCCH格式0的初始循环移位以及和PUCCH格式0的起始符号这三个参数不完全相同。较优的,同一个用于第一反馈方式的PUCCH资源集合内的不同的PUCCH占用不同的PRB或者不同的符号。
在一种实现方式中,在M小于或等于N的情况下,所述终端设备根据所述M比特HARQ反馈信息的比特状态,在所述第一G-RNTI关联的一个PUCCH资源集合中,确定所述用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PUCCH资源;
表示向下取整,K表示所述第一G-RNTI关联的一个PUCCH资源集合中的PUCCH资源的数量。
作为示例,M=2,K为3,终端设备按照下表确定采用的PUCCH资源。
表3
如表3所示,如果2比特HARQ反馈信息的比特状态为00,则使用第一G-RNTI对应的用于第一反馈方式的PUCCH资源集合中的第一个PUCCH资源发送PUCCH。如果2比特HARQ反馈信息的比特状态为01,则使用第一G-RNTI对应的用于第一反馈方式的PUCCH资源集合中的第二个PUCCH资源发送PUCCH。如果2比特HARQ反馈信息的比特状态为10,则使用第一G-RNTI对应的用于第一反馈方式的PUCCH资源集合中的第三个PUCCH资源发送PUCCH。如果2比特HARQ反馈信息的比特状态为11,则不发送任何PUCCH。
在一种实现方式中,在M大于N的情况下;所述方法200还可包括:
所述终端设备将所述M比特HARQ反馈信息划分为S个反馈信息组,S小于或等于N;所述终端设备将所述S个反馈信息组中的每一个反馈信息组包括的HARQ反馈信息,转换为1比特的针对反馈信息组的HARQ反馈信息,以得到所述S个反馈信息组的HARQ反馈信息;所述终端设备基于所述S个反馈信息组的HARQ反馈信息的比特状态,从该第一G-RNTI关联的一个PUCCH资源集合中,确定用于发送所述S个反馈信息组的包含NACK的HARQ反馈信息的PUCCH资源;所述S个反馈信息组的HARQ反馈信息包括所述S个反馈信息组的包含NACK的HARQ反馈信息;所述终端设备在所述用于发送所述S个反馈信息组的包含NACK的HARQ反馈信息的PUCCH资源上,发送所述S个反馈信息组的包含NACK的HARQ反馈信息。
作为示例,如果与第一G-RNTI关联的用于第一反馈方式的PUCCH资源集合中的PUCCH资源为3个,然而终端设备在时隙u需要反馈的所述第一G-RNTI对应的HARQ反馈信息的比特数大于2,则终端设备应将所有HARQ反馈信息分为两组,每组内的HARQ反馈信息通过“与”运算合并为1比特HARQ反馈信息,“与”运算的运算规则为0&0=0;0&1=0;1&0=0;1&1=1;然后,终端设备将最后确定的两比特HARQ反馈信息通过以上方式进行反馈。例如,终端设备在时隙u需要反馈2个所述第一G-RNTI加扰的PDCCH调度的PDSCH,每个PDSCH中承载两个传输块(TB),则终端 设备可以将每个PDSCH中的两个TB的HARQ信息比特进行“与”运算操作,得到1比特HARQ反馈信息。
在一种实现方式中,所述第一G-RNTI关联的一个PUCCH资源集合中不同的PUCCH资源用于发送不同比特状态下的HARQ反馈信息。
在一种实现方式中,所述终端设备配置有用于所述第一反馈方式的一个或多个PUCCH资源集合,所述一个或多个PUCCH资源集合中的不同的PUCCH资源集合对应不同的G-RNTI,所述一个或多个PUCCH资源集合包括所述第一G-RNTI关联的一个PUCCH资源集合。可选的,所述一个或多个PUCCH资源集合中的每一个PUCCH资源集合内的任何两个PUCCH资源的起始PRB、PUCCH格式0的初始循环移位以及PUCCH格式0的起始符号不完全相同。
在本申请的一些实施例中,所述终端设备在所述一个或多个PUCCH资源所在时隙内,确定所述第一G-RNTI对应的M比特HARQ反馈信息,M≥1;所述第一G-RNTI关联有一个PUCCH资源;所述S220可包括:
所述终端设备根据所述M比特HARQ反馈信息的比特状态,在所述第一G-RNTI关联的一个PUCCH资源中,确定用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PRB和/或符号;所述终端设备在所述用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PRB和/或符号上,发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息。
换言之,所述终端设备在一个时隙内存在M个针对一个G-RNTI的HARQ反馈信息,不同比特状态下的反馈信息使用不同的PRB和/或符号,其中M≥1。例如,所述终端设备在一个时隙内存在2个针对一个G-RNTI的HARQ反馈信息,所述2个针对一个G-RNTI的HARQ反馈信息为00、01或10时,使用的PRB和/或符号不同。
本实施例中,如果终端设备在所述第一G-RNTI关联的一个PUCCH资源所在时隙u内,所述第一G-RNTI对应的HARQ反馈信息为M比特HARQ反馈信息,M≥1,则终端设备根据所述M比特HARQ反馈信息的比特状态,确定在所述第一G-RNTI对应的用于第一反馈方式的PUCCH资源上发送PUCCH的方式。
在一种实现方式中,所述第一G-RNTI关联的一个PUCCH资源包括T*F个PRB,T≥1且,F≥1,T表示一个PUCCH资源包含的符号数,F表示一个PUCCH资源频域上包含的PRB个数。可选的,F>1,F个PRB是连续的。
即,本实施例中采用实施例1-1中的用于第一反馈方式的PUCCH资源配置方式,而且,对于每一个用于所述第一反馈方式的PUCCH资源包括T*F个PRB。
在一种实现方式中,在M小于或等于P情况下,所述终端设备根据所述M比特HARQ反馈信息的比特状态,在所述第一G-RNTI关联的一个PUCCH资源中,确定所述用于发送所述第一G-RNTI对应的包含NACK的HARQ反馈信息的PRB和/或符号,P表示所述第一G-RNTI关联的一个PUCCH资源中的PRB个数。
换言之,如果与所述第一G-RNTI关联的用于所述第一反馈方式的PUCCH资源包含的PRB个数为K个,则终端终端设备不希望在时隙u内,反馈大于K比特的所述第一G-RNTI对应的HARQ反馈信息。
作为一个示例,假设T=1,F=2,如果M=2,则终端设备按照下表确定在第一反馈方式的PUCCH资源上发送PUCCH的方式:
表4
如表4所示,如果2比特HARQ反馈信息的比特状态为00,则在PUCCH资源中的第一个和第二个PRB上发送PUCCH。如果2比特HARQ反馈信息的比特状态为01,则在PUCCH资源的第一个PRB上发送PUCCH,在PUCCH资源的第二个PRB上不发送任何信息。如果2比特HARQ反馈信息的比特状态为10,则在PUCCH资源的第二个PRB上发送PUCCH,在PUCCH资源的第一个PRB上不发送任何信息。如果2比特HARQ反馈信息的比特状态为11,则不发送任何PUCCH。
作为另一示例,假设T=2,F=1,如果M=2,则终端设备按照下表确定在第一反馈方式的PUCCH资源上发送PUCCH的方式:
表5
如表5所示,如果2比特HARQ反馈信息的比特状态为00,则在PUCCH资源的第一个和第二个符号上发送PUCCH。如果2比特HARQ反馈信息的比特状态为01,则在PUCCH资源的第一个符号上发送PUCCH,在PUCCH资源的第二个符号上不发送任何信息。如果2比特HARQ反馈信息的比特状态为10,则在PUCCH资源的第二个符号上发送PUCCH,在PUCCH资源的第一个符号上不发送任何信息。如果2比特HARQ反馈信息的比特状态为11,则不发送任何PUCCH。
作为另一示例,假设T=2,F=2,如果M=4,则终端设备按照下表确定在第一反馈方式的PUCCH资源的第一个符号和第二个符号上发送PUCCH的方式:
表6
如表6所示,如果前2比特HARQ反馈信息的比特状态为00,则在PUCCH资源的第1个符号的第一个和第二个PRB上发送PUCCH。如果前2比特HARQ反馈信息的比特状态为01,则在PUCCH资源的第1个符号的第一个PRB上发送PUCCH,在PUCCH资源的第二个PRB上不发送任何信息。如果前2比特HARQ反馈信息的比特状态为10,则在PUCCH资源的第1个符号的第二个PRB上发送PUCCH,在PUCCH资源的第一个PRB上不发送任何信息。如果前2比特HARQ反馈信息的比特状态为11,则不在PUCCH资源的第1个符号上发送PUCCH。
作为另一示例,假设T=2,F=2,如果M=4,则终端设备按照下表确定在第一反馈方式的PUCCH资源的第一个符号和第二个符号上发送PUCCH的方式:

在一种实现方式中,在M大于P的情况下;所述方法200还可包括:
所述终端设备将所述M比特HARQ反馈信息划分为S个反馈信息组,S小于等于P;所述终端设备将所述S个反馈信息组中的每一个反馈信息组包括的HARQ反馈信息,转换为1比特的针对反馈信息组的HARQ反馈信息,以得到所述S个反馈信息组的HARQ反馈信息;所述终端设备基于所述S个反馈信息组的HARQ反馈信息的比特状态,在所述第一G-RNTI关联的一个PUCCH资源中,确定用于发送所述S个反馈信息组的包含NACK的HARQ反馈信息的资源或符号;所述S个反馈信息组的HARQ反馈信息包括所述S个反馈信息组的包含NACK的HARQ反馈信息;所述终端设备在所述用于发送所述S个反馈信息组的包含NACK的HARQ反馈信息的资源或符号上,发送所述S个反馈信息组的包含NACK的HARQ反馈信息。
作为示例,如果与第一G-RNTI关联的用于第一反馈方式的PUCCH资源中的PRB为2个,然而终端设备在时隙u需要反馈的所述第一G-RNTI对应的HARQ反馈信息的比特数大于2,则终端设备应将所有HARQ反馈信息分为两组,每组内的HARQ反馈信息通过“与”运算合并为1比特HARQ反馈信息,“与”运算的运算规则为0&0=0;0&1=0;1&0=0;1&1=1;然后,终端设备将最后确定的两比特HARQ反馈信息通过以上方式进行反馈。例如,终端设备在时隙u需要反馈2个所述第一G-RNTI加扰的PDCCH调度的PDSCH,每个PDSCH中承载两个传输块(TB),则终端设备可以将每个PDSCH中的两个TB的HARQ信息比特进行“与”运算操作,得到1比特HARQ反馈信息。
