Description

一种信息确定方法及装置、终端设备 技术领域
本申请实施例涉及移动通信技术领域，具体涉及一种信息确定方法及装置、终端设备。
背景技术
在新无线(New Radio，NR)***中，很多场景需要支持组播类型的业务需求，例如车联网中，工业互联网中等。所以在NR中引入组播类型的多媒体广播服务(Multimedia Broadcast Service，MBS)业务是有必要的。
对于组播类型的MBS业务来说，其使用的混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)进程标识与单播业务使用的HARQ进程标识属于相同的标识空间。而对于MBS业务来说，其传输类型又可以分为MBS动态调度的传输和MBS半持续调度(Semi-Persistent Scheduling，SPS)的传输；对于单播业务来说，其传输类型可以分为单播动态调度的传输和单播SPS的传输。当这些不同传输类型之间的HARQ进程标识冲突或者相同时，由于数据的初始传输和重传输也关联相同的HARQ进程标识，这导致终端设备无法明确网络侧的调度是一个数据的初始传输还是重传输，无法正确处理数据接收。
发明内容
本申请实施例提供一种信息确定方法及装置、终端设备、芯片、计算机可读存储介质、计算机程序产品、计算机程序。
本申请实施例提供的信息确定方法，包括：
终端设备接收第一调度信令，所述第一调度信令通过第一无线网络临时标识(Radio Network Tempory Identity，RNTI)加扰，其中，所述第一调度信令携带HARQ进程标识和新数据指示信息(New Data Indication，NDI)；
所述终端设备基于所述第一RNTI和/或所述HARQ进程标识对应的前一次调度方式，确定所述NDI的翻转情况和/或所述NDI的值。
本申请实施例提供的信息确定装置，应用于终端设备，所述装置包括：
接收单元，用于接收第一调度信令，所述第一调度信令通过第一RNTI加扰，其中，所述第一调度信令携带HARQ进程标识和NDI；
确定单元，用于基于所述第一RNTI和/或所述HARQ进程标识对应的前一次调度方式，确定所述NDI的翻转情况和/或所述NDI的值。
本申请实施例提供的终端设备，包括处理器和存储器。该存储器用于存储计算机程序，该处理器用于调用并运行该存储器中存储的计算机程序，执行上述的信息确定方法。
本申请实施例提供的芯片，用于实现上述的信息确定方法。
具体地，该芯片包括：处理器，用于从存储器中调用并运行计算机程序，使得安装有该芯片的设备执行上述的信息确定方法。
本申请实施例提供的计算机可读存储介质，用于存储计算机程序，该计算机程序 使得计算机执行上述的信息确定方法。
本申请实施例提供的计算机程序产品，包括计算机程序指令，该计算机程序指令使得计算机执行上述的信息确定方法。
本申请实施例提供的计算机程序，当其在计算机上运行时，使得计算机执行上述的信息确定方法。
通过上述技术方案，终端设备接收到第一调度信令时，基于加扰第一调度信令的第一RNTI(也即第一调度信令对应的调度方式)和/或第一调度信令中携带的HARQ进程标识对应的前一次调度方式，确定第一调度信令中携带的NDI的翻转情况和/或NDI的值，由于NDI的翻转情况和/或NDI的值代表了第一调度信令调度的数据是初始传输还是重传，因而终端设备可以正确处理数据接收。

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***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***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***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***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***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。
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，MBS业务在动态调度传输过程中使用的HARQ进行标识是通过网络侧指定的，与单播业务的HARQ进行标识的标识空间是相同的。如果为MBS业务配置了SPS，则每个SPS的传输资源是通过公式计算其HARQ进行标识，该HARQ进行标识与单播业务的HARQ进行标识的标识空间是相同的。作为示例：MBS SPS的传输资源的HARQ进行标识可以通过以下公式计算：
HARQ Process ID＝[floor(CURRENT_slot×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes；
其中，CURRENT_slot＝[(SFN×numberOfSlotsPerFrame)+slot number in the frame]，numberOfSlotsPerFrame代表每帧对应的连续时隙数。
对于配置了harq-ProcID-Offset的下行分配，HARQ进行标识可以通过以下公式计算：HARQ Process ID＝[floor(CURRENT_slot×10/(numberOfSlotsPerFrame×periodicity))]modulo nrofHARQ-Processes+harq-ProcID-Offset
其中，CURRENT_slot＝[(SFN×numberOfSlotsPerFrame)+slot number in the frame]，numberOfSlotsPerFrame代表每帧对应的连续时隙数。
综上，对于组播类型的MBS业务来说，其使用的HARQ进程标识与单播业务使用的HARQ进程标识属于相同的标识空间。而对于MBS业务来说，其传输类型又可以分为MBS动态调度的传输和MBS SPS的传输；对于单播业务来说，其传输类型可以分为单播动态调度的传输和单播SPS的传输。当这些不同传输类型之间的HARQ进程标识冲突或者相同时，由于数据的初始传输和重传输也关联相同的HARQ进程标识，这导致终端设备无法明确网络侧的调度是一个数据的初始传输还是重传输，无法正确处理数据接收。为此，提出了本申请实施例的以下技术方案。
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信息确定方法的流程示意图，如图3所示，所述信息确定方法包括以下步骤：
步骤301：终端设备接收第一调度信令，所述第一调度信令通过第一RNTI加扰，其中，所述第一调度信令携带HARQ进程标识和NDI。
在一些可选实施方式中，终端设备接收第一调度信令之前，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、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。
步骤302：所述终端设备基于所述第一RNTI和/或所述HARQ进程标识对应的前一次调度方式，确定所述NDI的翻转情况和/或所述NDI的值。
本申请实施例中，第一调度信令可以是DCI，即DCI通过第一RNTI加扰。所述第一调度信令用于调度第一数据，其中，所述第一调度信令携带HARQ进程标识和NDI， 所述HARQ进程标识为所述第一数据关联的HARQ进程标识，所述NDI用于指示所述第一数据是新传数据还是重传数据。然而，由于不同传输类型之间的HARQ进程标识可能会冲突或者相同，因此终端设备基于所述第一RNTI和/或所述HARQ进程标识对应的前一次调度方式，确定所述NDI的翻转情况和/或所述NDI的值，进而确定第一数据是新传数据还是重传数据。
本申请实施例中，调度方式可以有如下几类：C-RNTI加扰的调度、G-RNTI加扰的调度、MBS SPS的授权、组-配置调度-无线网络临时标(G-CS-RNTI)加扰的调度、单播SPS的授权、调度-无线网络临时标识(CS-RNTI)加扰的调度。其中，MBS SPS的授权与G-CS-RNTI加扰的调度是对应的(或者说一致的)，单播SPS的授权和CS-RNTI加扰的调度是对应的(或者说一致的)。C-RNTI加扰的调度可以理解为单播动态调度，单播SPS的授权和CS-RNTI加扰的调度可以理解为单播半持续调度。G-RNTI加扰的调度可以理解为MBS动态调度，MBS SPS的授权和G-CS-RNTI加扰的调度可以理解为MBS半持续调度。
方案一
在一些可选实施方式中，所述第一RNTI为C-RNTI的情况下，若所述HARQ进程标识对应的前一次调度方式为G-RNTI加扰的调度、或者MBS SPS的授权、或者组-配置调度-无线网络临时标(G-CS-RNTI)加扰的调度，则所述终端设备确定所述NDI翻转。
方案二
在一些可选实施方式中，所述第一RNTI为G-RNTI的情况下，若所述HARQ进程标识对应的前一次调度方式为MBS SPS的授权、或者G-CS-RNTI加扰的调度、或者单播SPS的授权、或者CS-RNTI加扰的调度，则所述终端设备确定所述NDI翻转。
方案三
在一些可选实施方式中，所述第一RNTI为CS-RNTI的情况下，若所述HARQ进程标识对应的前一次调度方式为MBS SPS的授权、或者G-CS-RNTI加扰的调度，则所述终端设备确定所述NDI翻转。
在一些可选实施方式中，所述第一RNTI为CS-RNTI的情况下，所述终端设备确定所述NDI未翻转和/或所述NDI的值固定为1。
方案四
在一些可选实施方式中，所述第一RNTI为第一G-RNTI的情况下，若所述HARQ进程标识对应的前一次调度方式为第二G-RNTI加扰的调度，则所述终端设备确定所述NDI翻转。
方案五
在一些可选实施方式中，所述第一RNTI为第一G-CS-RNTI的情况下，若所述HARQ进程标识对应的前一次调度方式为第二G-CS-RNTI加扰的调度、或者第二MBS SPS的授权，则所述终端设备确定所述NDI翻转。
在一些可选实施方式中，所述第一RNTI为第一G-CS-RNTI的情况下，所述终端设备确定所述NDI未翻转和/或所述NDI的值固定为1。
上述方案中，若终端设备确定NDI翻转，则认为第一调度信令调度的是新传数据。若终端设备确定NDI未翻转和/或NDI的值固定为1，则认为第一调度信令调度的是重传数据。终端设备根据确定出的NDI翻转的情况和/或NDI的值，可以正确接收数据。
在一些可选实施方式中，所述终端设备向网络设备发送第一信息，这里，所述第一信息用于所述网络设备进行数据调度。所述第一信息包括第一指示信息和/或第二 指示信息，其中，所述第一指示信息用于指示以下至少两种调度方式之间的优先级关系：C-RNTI加扰的调度、G-RNTI加扰的调度、MBS SPS的授权、G-CS-RNTI加扰的调度、单播SPS的授权、CS-RNTI加扰的调度；所述第二指示信息用于指示以下至少之一：不同G-RNTI加扰的调度之间的优先级关系、不同MBS SPS的授权之间的优先级关系、不同G-CS-RNTI加扰的调度之间的优先级关系。如此，网络设备基于终端设备给出的第一信息可以合理的进行数据调度。
上述方案中，所述第一信息可以携带在RRC专用信令中，即终端设备通过RRC专用信令指示网络侧调度方式之间的优先级关系。
