  • mMTC Massive Machine Type Communication
  • URLLC Ultra-reliable and Low Latency Communications.
  • the data generated by the mMTC service is usually small data (that is, each data packet is relatively small).
  • the data transmission occupies much less resources than the signaling interaction before the data transmission (for example, The resources used by the scheduling interaction between the scheduling request and the scheduling authorization process, or the signaling interaction of the random access procedure, which results in low resource utilization, especially in the case of a large number of mMTC devices, the system resources will be largely It is occupied by interactive signaling; the URLLC service requires low latency, and the signaling interaction in the above Grant-based UL transmission process has a large delay due to RRC signaling, so the traditional Grant-based UL transmission It is also difficult to meet the needs of the URLLC business.
  • 5G introduces a Grant-free (also called transmission without grant or Grant-less) transmission method for UL transmission in New Radio (NR).
  • the so-called Grant-free transmission mode means that the UE does not need to request the UL transmission resource from the base station when the data needs to be transmitted, but is selected according to a certain rule in the transmission resource pool (which can be called a Grant-free transmission resource pool) pre-configured by the base station.
  • a transmission unit for UL transmission directly performs UL transmission. In this way, the signaling interaction in the Grant-based UL transmission process can be omitted, thereby reducing signaling overhead and transmission delay, and is particularly suitable for packet transmission and delay sensitive services.
  • the 5G-NR standard has explicitly agreed that mMTC and URLLC support Grant-free transmission.
  • the standard also determines the time-frequency resource used by the base station to configure the Grant-free transmission, that is, configures the Grant-free transmission resource pool.
  • Each Grant-free transmission resource pool includes one or more transmission units. When the UE has data to transmit, one or more transmission units are selected for transmission from the configured Grant-free transmission resource pool.
  • the same Grant-free transmission resource pool is generally configured for multiple UEs at the same time. In this case, although the transmission may fail due to the collision of different UEs selecting the same transmission unit, for the service when the UE is not sure when to arrive, Since multiple UEs share the same Grant-free transmission resource, resource utilization efficiency can be improved.
  • the Grant-free transmission resource pool configured by the base station to one UE is usually periodic, and in one cycle, the base station can configure multiple Grant-free transmission resource pools for one UE.

  • One method of performing HARQ acknowledgment on Grant-free transmissions is to use a UL Grant (UL Grant) message.
  • the base station After the base station receives the Grant-free data sent by the UE (correctly decoded or not correctly decoded), and other UL data of the UE needs to be sent, the base station sends a UL Grant message to the UE, where the UE carries the Grant-free ACK/NACK information of the data.
  • the UL Grant message needs to be carried by using a Physical Downlink Control Channel (PDCCH) (ie, using DCI in the PDCCH), and each PDCCH needs to occupy at least one physical resource of the CCE.
  • PDCCH Physical Downlink Control Channel
  • the base station needs to send a large number of UL Grants, that is, a large number of PDCCHs, thereby causing a great waste of resources.

技术领域
本申请实施例涉及通信技术，尤其涉及一种数据传输的确认方法及设备。
背景技术
传统蜂窝通信系统中，如长期演进(Long Term Evolution，LTE)，上行(Uplink，UL)传输中采用基于授权(Grant-based)的方式，即基站调度UE进行UL传输的资源以及相关传输参数，例如UL传输所使用时域、频域、空域资源以及调制编码方案(Modulation and Coding Scheme，MCS)。上述基于授权(Grant-based)的UL传输过程都需要较多信令开销，并且这些信令交互不可避免地会带来延迟。
在3GPP制定的蜂窝通信的第五代标准(5th Generation，5G)中，考虑的场景包括海量机器类型通信(Massive Machine Type Communication，mMTC)和高可靠低时延通信(Ultra-reliable and Low Latency Communications，URLLC)。其中，mMTC业务产生的数据通常是小数据(即每个数据包比较小)，若采用传统Grant-based的UL传输方式，则数据传输所占据的资源远小于数据传输之前的信令交互(如调度请求和调度授权过程的信令交互，或者，随机接入过程的信令交互)所使用的资源，这导致资源利用率低下，特别是在有大量mMTC设备的情况下，系统资源将大量地被交互信令所占据；URLLC业务要求低延时，而上述Grant-based的UL传输过程中的信令交互，由于涉及RRC信令，其延迟是很大的，因此传统Grant-based的UL传输方式也很难满足URLLC业务的需求。
基于上述原因，5G在新无线(New Radio，NR)中引入了免授权(Grant-free，又称为transmission without grant或Grant-less)传输方式，用于UL传输。所谓Grant-free传输方式，是指UE有数据需要传输时无需向基站请求UL传输资源，而是在基站预先配置的传输资源池(可称为Grant-free传输资源池)中基于某种规则选择一个用于UL传输的传输单元直接进行UL传输。这样，便可以省去Grant-based的UL传输过程中的信令交互，从而降低了信令开销和传输延时，特别适合于小包传输以及延时敏感业务。
5G-NR标准已经明确同意mMTC和URLLC支持Grant-free传输。另外，标准还确定由基站配置Grant-free传输所使用的时频资源，即配置Grant-free传输资源池。每个Grant-free传输资源池中包括一个或多个传输单元，当UE有数据需要传输时，从配置给自己的Grant-free传输资源池中选择一个或多个传输单元进行传输。同一个Grant-free传输资源池一般同时配置给多个UE，这种情况下，虽然可能由于不同UE 选择相同传输单元发生碰撞而导致传输失败，但对于UE不确定何时到达的业务来说，由于多个UE共享相同的Grant-free传输资源，能够提高资源的利用效率。基站配置给一个UE的Grant-free传输资源池通常是周期性的，并且在一个周期内，基站可以给一个UE配置多个Grant-free传输资源池。Grant-free传输资源池也可简称为Grant-free资源。
当UE在配置给自己的Grant-free资源上发送了数据之后，期望收到基站发送的混合自动重传请求(Hybrid Automatic Repeat reQust，HARQ)确认，即肯定应答(Acknowledgement，ACK)/否定应答(Negative Acknowledgement，NACK)，表示基站是否正确接收UE发送的数据。一种对Grant-free传输进行HARQ确认的方法是采用UL Grant(UL授权)消息。当基站接收到UE发送的Grant-free数据后(正确解码或未正确解码)，恰好有该UE的其它UL数据需要发送，则基站向该UE发送UL Grant消息，其中携带该UE的Grant-free数据的ACK/NACK信息。
然而，UL Grant消息需使用物理下行控制信道(Physical Downlink Control Channel，PDCCH)(即利用PDCCH中的DCI)来承载，而每个PDCCH至少需占据一个CCE的物理资源。当有较多UE的UL数据需要确认时，基站需发送大量UL Grant，即大量PDCCH，从而造成资源的极大浪费。并且，一个下行子帧的控制部分的资源是有限的，往往很难承载大量PDCCH。

本申请提供的实施例包括以下任一个:
实施例1、一种数据传输的确认方法，所述方法包括：
网络设备在第一GF资源上接收终端设备发送的第一数据，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，N≥1；
所述网络设备向所述终端设备发送HARQ确认消息，所述HARQ确认消息与所述第一GF资源组对应，所述HARQ确认消息中包括所述第一数据的确认信息。
N个GF资源对应一个HARQ确认消息，而每个GF资源能够容纳的UE数目上限是确定的(取决于可用的DMRS数目)，这使得HARQ确认消息中的Bitmap长度固定，进而使HARQ确认消息长度固定，这有利于降低UE接收HARQ确认消息时的盲检次数，从而使UE更加省电。
实施例2、根据实施例1所述的方法，在所述网络设备在第一GF资源上接收终端设备发送的第一数据之前，所述网络设备向所述终端设备发送配置信息，所述配置信息包括所述第一GF资源组对应的G-RNTI，所述G-RNTI用于对所述HARQ确认消息进行加扰。
基于G-RNTI生成扰码序列来加扰HARQ确认消息，从而区分不同GF资源组对应的HARQ确认消息。由于采用加扰的方法，G-RNTI不必显式携带在HARQ确认消息中，这有利于降低HARQ确认消息的传输开销。
实施例3、根据实施例1所述的方法，在所述网络设备在第一GF资源上接收终端设备发送的第一数据之前，所述网络设备向所述终端设备发送配置信息，所述配置信息包括所述第一GF资源组对应的组标识，所述HARQ确认消息中包括所述组标识。
资源组对应的组标识显式携带在HARQ确认消息中，用于区分不同GF资源组对应的HARQ确认消息。相比加扰的方法，这种显式携带的方法显然会增加HARQ确认消息的传输开销，但同时具有灵活性高的优点，有利于存在较多GF资源组情况下的不同HARQ确认消息的指示。
实施例4、根据实施例1-3任一所述的方法，在所述网络设备在第一GF资源上接 收终端设备发送的第一数据之前，所述网络设备向所述终端设备发送配置信息，所述配置信息包括所述终端设备在位表中的位置索引，所述HARQ确认消息包括所述位表，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
基站指示UE在HARQ确认消息的Bitmap中的位置索引，使得UE据此确定HARQ确认消息的Bitmap中哪个或哪些比特与自己发送的数据对应，从而根据对应位置上的比特值确定基站是否正确接收对应数据。
实施例5、根据实施例1-3任一所述的方法，在所述网络设备在第一GF资源上接收终端设备发送的第一数据之前，所述网络设备向所述终端设备发送配置信息，所述配置信息包括所述第一GF资源的资源索引和所述终端设备在所述终端设备在所述第一GF资源中的DMRS索引，所述资源索引是所述第一GF资源在所述第一GF资源组中的排序。
基站为UE指示资源索引和DMRS索引，使得UE基于这两个索引确定自身在HARQ确认消息的Bitmap中的位置索引。由于DMRS索引并不仅用于本申请，而是GF传输的基本配置，故仅资源索引是本申请新增指示。显然，相比基站直接配置UE的位置索引的方法，本实施例中基站配置资源索引的指示开销更小。
实施例6、根据实施例1-5任一所述的方法，所述N的值是预定义的，或，所述N的值是所述网络设备配置的。
N为标准预定义或由基站配置，使得对于UE来说，N是确定值，这使得HARQ确认消息中的Bitmap长度固定，进而使HARQ确认消息长度固定，这有利于降低UE接收HARQ确认消息时的盲检次数，从而使UE更加省电。
实施例7、一种数据传输的确认方法，所述方法包括：
终端设备在第一GF资源上向网络设备发送第一数据，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，N≥1；
所述终端设备接收所述网络设备发送的HARQ确认消息，所述HARQ确认消息与所述第一GF资源组对应，所述HARQ确认消息中包括所述第一数据的确认信息。
N个GF资源对应一个HARQ确认消息，而每个GF资源能够容纳的UE数目上限是确定的(取决于可用的DMRS数目)，这使得HARQ确认消息中的Bitmap长度固定，进而使HARQ确认消息长度固定，这有利于降低UE接收HARQ确认消息时的盲检次数，从而使UE更加省电。
实施例8、根据实施例7所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备接收所述网络设备发送的配置信息，所述配置信息包括所述第一GF资源组对应的G-RNTI，所述G-RNTI用于对所述HARQ确认消息进行解扰。
基于G-RNTI生成扰码序列来加扰HARQ确认消息，从而区分不同GF资源组对应的HARQ确认消息。由于采用加扰的方法，G-RNTI不必显式携带在HARQ确认消息中，这有利于降低HARQ确认消息的传输开销。
实施例9、根据实施例7所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备接收所述网络设备发送的配置信息，所述配置信息包括所述第一GF资源组对应的组标识，所述HARQ确认消息中包括所述组标识。
资源组对应的组标识显式携带在HARQ确认消息中，用于区分不同GF资源组对应的HARQ确认消息。相比加扰的方法，这种显式携带的方法显然会增加HARQ确认消息的传输开销，但同时具有灵活性高的优点，有利于存在较多GF资源组情况下的不同HARQ确认消息的指示。
实施例10、根据实施例7所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备根据所述第一GF资源组所在子帧或时隙或微时隙的索引确定所述第一GF资源组对应的G-RNTI，所述G-RNTI用于对所述HARQ确认消息进行解扰。
UE根据第一GF资源组所在子帧或时隙或微时隙的索引来确定G-RNTI，这样就无需基站通过信令配置G-RNTI，有利于降低配置开销。
实施例11、根据实施例7所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备根据所述第一GF资源组所在子帧或时隙或微时隙的索引确定所述第一GF资源组对应的组标识，所述HARQ确认消息中包括所述组标识。
UE根据第一GF资源组所在子帧或时隙或微时隙的索引来确定组标识，这样就无需基站通过信令配置组标识，有利于降低配置开销。
实施例12、根据实施例7-11任一所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备接收所述网络设备发送的配置信息，所述配置信息包括所述终端设备在位表中的位置索引，所述HARQ确认消息包括所述位表，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
基站指示UE在HARQ确认消息的Bitmap中的位置索引，使得UE据此确定HARQ确认消息的Bitmap中哪个或哪些比特与自己发送的数据对应，从而根据对应位置上的比特值确定基站是否正确接收对应数据。
实施例13、根据实施例7-11任一所述的方法，在所述终端设备在第一GF资源上向网络设备发送第一数据之前，所述终端设备接收所述网络设备发送的配置信息，所述配置信息包括所述第一GF资源的资源索引和所述终端设备在所述终端设备在所述第一GF资源中的DMRS索引，所述资源索引是所述第一GF资源在所述第一GF资源组中的排序。
基站为UE指示资源索引和DMRS索引，使得UE基于这两个索引确定自身在HARQ确认消息的Bitmap中的位置索引。由于DMRS索引并不仅用于本申请，而是GF传输的基本配置，故仅资源索引是本申请新增指示。显然，相比基站直接配置UE的位置索引的方法，本实施例中基站配置资源索引的指示开销更小。
实施例14、根据实施例13所述的方法，所述终端设备基于所述资源索引和所述DMRS索引，确定所述终端设备在位表中的位置索引，所述HARQ确认消息包括所述位表，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
实施例15、根据实施例7-14任一所述的方法，所述N的值是预定义的，或，所述N的值是所述网络设备配置的。
N为标准预定义或由基站配置，使得对于UE来说，N是确定值，这使得HARQ确认消息中的Bitmap长度固定，进而使HARQ确认消息长度固定，这有利于降低UE接收 HARQ确认消息时的盲检次数，从而使UE更加省电。

具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。
本申请所涉及的“/”表示或的关系，例如，A/B可以表示：单独存在A、单独存在B这两种情况。
本申请所涉及的“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A、单独存在B，同时存在A和B这三种情况。
图1为本申请涉及的通信系统的框架图。本申请提供的数据传输的确认方法适用于如图1所示的通信系统，该通信系统可以是LTE通信系统，也可以是其他通信系统(例如5G通信系统)，在此不作限制。如图1所示，该通信系统包括：网络设备和终端。
其中，网络设备：可以是基站，或者接入点，或者可以是指接入网中在空中接口上通过一个或多个扇区与无线终端通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为无线终端与接入网的其余部分之间的路由器，其中接入网的其余部分可包括网际协议(IP)网络。基站还可协调对空中接口的属性管理，为终端分配传输资源。例如，基站可以是全球移动通讯(Global System of Mobile communication，GSM)或码分多址(Code Division Multiple Access，CDMA)中的基站(Base Transceiver Station，BTS)，也可以是宽带码分多址(Wideband Code Division Multiple Access，WCDMA)中的基站(NodeB，NB)，还可以是长期演进(Long Term Evolution，LTE)中的演进型基站(Evolutional Node B，eNB或eNodeB)，或者中继(Relay)站或接入点(Access Point，AP)，或者热点(pico)，或者家庭基站(Femeto)，或者5G网络中的基站等，在此并不限定。
终端：可以是无线终端也可以是有线终端，无线终端可以是指向用户提供语音和/或其他业务数据连通性的设备，具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备。无线终端可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，无线终端可以是移动终端，如移动电话(或称为“蜂窝”电话)和具有移动终端的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。例如，个人通信业务(Personal Communication Service，PCS)电话、无绳电话、会话发起协议(Session Initiation Protocol，SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、手机、电脑、手环、智能手表、数据卡、传感器等设备。无线终端也可以称为系统、订户单元(Subscriber Unit)、订户站(Subscriber Station)，移动站(Mobile Station)、移动台(Mobile)、远程站(Remote Station)、远程终端(Remote Terminal)、接入终端(Access Terminal)、用户终端(User Terminal)、用户代理(User Agent)、用户设备(User Device or User Equipment)，在此不作限定。
需要说明的是。对于Sidelink(副链路)，即设备到设备(Device to Device，D2D)，例如，手环-手机-基站中手环与手机之间的链路，手环可视为终端，而手机视为基站。
本申请所涉及的“混合自动重传请求确认(HARQ ACK)消息”被携带在组公共下行控制信息(Group common DCI，G-DCI)中，该G-DCI通过PDCCH发送。承载G-DCI的PDCCH又可称为组公共物理下行控制信道(Group common PDCCH)。网络设备可以向通过一个GF资源组传输数据的一个或多个终端发送一个HARQ ACK消息，即一个HARQACK消息中包括该一个或多个终端通过一个GF资源组发送的数据的确认信息，本申请实施例将对该一个或多个终端发送的数据进行确认的HARQ ACK消息称之为“目标HARQ ACK消息”。该目标HARQ ACK消息可以包括一个或多个HARQ ACK消息，例如，该一个或多个终端通过多个GF资源传输数据，则该目标HARQ ACK消息包括多个HARQ ACK消息，一个HARQ ACK消息与一个GF资源组对应。
需要说明的是，G-DCI、HARQ ACK消息、目标HARQ ACK消息仅为一种消息名称，其消息名称并不以此作为限制。
本申请的网络设备将每N个免授权(Grant-free，GF)资源分为一组，同一GF资源只能位于一个组中，N≥1。其中，使用组标识(group ID)标识不同的GF资源组。每个GF资源组对应一个混合自动重传请求确认(HARQ ACK)消息，即使用一个HARQ确认消息对所有在该GF资源组中发送数据的终端进行回复。换句话说，所有在该GF资源组(可以是其中任一GF资源或多个GF资源)中传输的数据所对应的确认信息包含在同一HARQ ACK消息中，这些数据可以来自一个终端，也可以来自多个终端。不同GF资源组对应的HARQ ACK消息，用对应GF资源组的组标识(group ID)进行区分。其中，HARQ ACK消息具体可以携带在组公共下行控制信息(Group common DCI，G-DCI)，该G-DCI中包括位图信息(Bitmap)，用于对在该HARQ ACK消息对应的N个GF资源上传输的数据进行HARQ确认。
其中，N的具体取值可以是标准预定义的，也可以是由网络设备配置的。网络设备可通过无线资源控制(Radio Resource Control，RRC)信令、媒体访问控制控制元素(Media Access Control Control Element，MAC CE)或物理层信令为终端配置N的取值。
本申请涉及的GF资源，也可以称之为GF传输资源，该GF资源可以包括但不限于以下资源的一种或多种的组合：时域资源(也可以称为时间资源)，如无线帧、子帧、符号等；频域资源(也可以称为频谱资源)，如子载波、资源块等；空域资源，如发送天线、波束等；码域资源，如稀疏码多址接入(Sparse Code Multiple Access，SCMA)码本、低密度签名(Low Density Signature，LDS)序列、CDMA码等；以及，上行导频资源。
举例而言，图2为本申请的N＝2时的GF资源组与G-DCI的示意图，其中，GF资源1和GF资源2分为第一组，可以用G-ID1(group ID1)标识；GF资源3和GF资源4分为第二组，用G-ID2(group ID2)标识。G-ID1的GF资源组对应的HARQ ACK消息为G-DCI1，G-ID2的GF资源组对应的HARQ ACK消息为G-DCI2。当UE在GF资源1和/或GF资源2中进行数据传输时，则在G-DCI1中接收对应的确认消息；当UE在GF 资源3和/或GF资源4中进行数据传输时，则在G-DCI2中接收对应的确认消息。需要说明的是，网络设备可以将多个GF资源配置配给同一UE。例如，网络设备将GF资源1和GF资源2都配置给UE1，则在G-DCI1中有两个比特与UE1对应，即分别对应UE1在GF资源1和GF资源2中发送的数据的确认。再如，网络设备将GF资源1和GF资源4配置给UE2，且UE2在两个GF资源上都发送了数据，则UE2需分别接收G-DCI1和G-DCI2，以获得其在GF资源1和GF资源4上发送数据的确认。
本申请通过上述方式将多个GF资源进行分组，每个GF资源组对应一个HARQ ACK消息，通过HARQ ACK消息向终端反馈GF资源组中的GF资源上传输的数据的确认，该GF资源上传输数据的终端可以包括一个或多个终端，即基于GF资源分组达到终端分组的目的，同组GF资源对应的终端映射至同一个HARQ ACK消息进行数据传输的确认，从而可以减少相关信令开销。
本文所涉及的“第一终端”和“第二终端”仅用于区分通信网络中不同的终端，即上述图1所示的通信系统中可以包括多个终端，该多个终端中的一个或者多个可以使用GF资源进行数据传输，通过本申请实施例的数据传输的确认方法对该GF资源上传输的数据进行确认。其中，第二终端也可以执行下述实施例中第一终端执行的相关方法步骤。下述实施例采用第一终端和网络设备进行举例说明。
本申请的数据传输的确认方法的具体解释说明可以参见下述实施例的具体解释说明。
图3为本申请的一种数据传输的确认方法的流程图，本实施例涉及网络设备和终端，如图3所示，本实施例的方法可以包括：
步骤101、第一终端在第一GF资源上向网络设备发送第一数据。
相应的，网络设备在第一GF资源上接收第一终端发送的第一数据。
其中，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，N≥1。
具体的，该第一GF资源组包括N个GF资源，终端可以使用N个GF资源中一个或多个GF资源发送第一数据，该一个或多个GF资源即为该第一GF资源。
步骤102、所述网络设备向所述第一终端发送目标HARQ确认消息。
相应的，第一终端接收网络设备发送的目标HARQ确认消息。
其中，所述目标HARQ确认消息与所述第一GF资源组对应，所述目标HARQ确认消息用于对在所述第一GF资源组的GF资源上传输的所有终端的数据进行确认，所述所有终端包括所述第一终端，所述所有终端的数据包括所述第一数据，即该所述目标HARQ确认消息中包括所述第一数据的确认信息。
可以理解的，网络中可以有一个或多个终端使用第一GF资源组中的GF资源进行数据传输，上述第一终端为上述一个或多个终端中的一个终端，网络设备可以通过一个目标HARQ确认消息对在该第一GF资源组的GF资源上传输的一个或多个终端的数据进行确认。举例而言，网络中第一终端和第二终端使用第一GF资源组中的GF资源进行数据传输，网络设备可以通过一个目标HARQ确认消息对在该第一GF资源组的GF资源上传输的第一终端和第二终端的数据进行确认。
具体的，网络设备根据一个或多个终端传输的数据的接收情况，该一个或多个终 端传输的数据包括第一终端的第一数据，生成该目标HARQ确认消息，即网络设备向一个或多个终端反馈通过第一GF资源组的GF资源传输的所有终端的数据的确认信息。
本实施例，通过第一终端在第一GF资源上向网络设备发送第一数据，其中，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，网络设备向所述终端发送目标HARQ确认消息，所述目标HARQ确认消息与所述第一GF资源组对应，所述目标HARQ确认消息用于对在所述第一GF资源组的GF资源上传输的所有终端的数据进行确认，所述所有终端包括所述第一终端，所述所有终端的数据包括所述第一数据，实现通过目标HARQ确认消息对在GF资源组中的GF资源上传输的所有终端的数据进行确认，该GF资源组上传输数据的终端可以包括一个或多个终端，即基于GF资源分组达到终端分组的目的，同组GF资源对应的终端映射至同一个HARQ确认消息进行数据传输的确认，从而可以减少相关信令开销。
下面采用几个具体的实施例，对图3所示方法实施例的技术方案进行详细说明。
图4为本申请的另一种数据传输的确认方法的流程图，如图4所示，本实施例在上述实施例的基础上，通过加扰、解扰组标识的方式实现接收和识别第一GF资源组对应的目标HARQ确认消息，本实施例的方法可以包括：
终端在网络设备配置的GF资源中传输数据之后，到对应的下行子帧/时隙/微时隙接收HARQ确认消息，该下行子帧/时隙/微时隙可以称之为“目标HARQ确认时机”。该目标HARQ确认时机通常包括多个可用于传输下行控制信息(DCI和/或G-DCI)的时频资源(即DCI和/或G-DCI搜索空间)，终端在该目标HARQ确认时机盲检与自己传输使用的GF资源所属GF资源组对应的HARQ确认消息(称为目标HARQ确认消息)，即G-DCI。当终端在目标HARQ确认时机中收到一个消息，可以通过下述步骤确定该消息是否是自己期望的目标HARQ确认消息，即可以确定接收到的HARQ确认消息是否是自己传输使用的GF资源所属GF资源组对应的HARQ确认消息。下述实施例中采用第一终端做举例说明，通信网络中的其他终端可以执行相同的方法步骤，此处不再赘述。
步骤201、第一终端在第一GF资源上向网络设备发送第一数据。
其中，第一GF资源属于第一GF资源组。
相应的，网络设备在第一GF资源上接收第一终端发送的第一数据。
其中，步骤201的具体解释说明可以参见上述图3所示实施例的步骤101，此处不再赘述。
步骤202、网络设备向第一终端发送HARQ确认消息。
具体的，网络设备根据一个或多个终端在第一GF资源组中的传输的数据的接收情况，该一个或多个终端传输的数据包括第一终端的第一数据，生成目标HARQ确认消息，即网络设备向一个或多个终端反馈通过第一GF资源组中的GF资源传输的所有终端的数据的确认信息。本实施例中，所述网络设备还可以根据所述第一GF资源组的组标识对所述目标HARQ确认消息进行加扰，然后，所述网络设备向一个或多个终端发送加扰后的目标HARQ确认消息。其中，由于网络设备还可以对其他GF资源组的数据进行确认，所以，网络设备可以发送多个HARQ确认消息，每个HARQ确认消息对应一个GF资源组，其中一个HARQ确认消息即为加扰后的目标HARQ确认消息(即第一GF资源组对应的HARQ确认消息)。
其中，网络设备根据所述第一GF资源组的组标识对所述目标HARQ确认消息进行加扰的具体实现方式可以为，基于第一GF资源组的组标识产生扰码序列，使用扰码序列对承载该所述目标HARQ确认消息的G-DCI的负载(payload)的循环冗余效验(Cyclic Redundancy Check，CRC)进行加扰。
第一终端接收网络设备发送的HARQ确认消息，第一终端需要通过下述步骤203，以确定接收到的HARQ确认消息是否为自身的目标HARQ确认消息。
步骤203、所述第一终端使用第一GF资源组的组标识对所述HARQ确认消息进行解扰，当所述HARQ确认消息被正确解扰时，则确定所述HARQ确认消息为目标HARQ确认消息，所述目标HARQ确认消息与所述第一GF资源组对应。
具体的，第一终端使用组标识对接收到的HARQ确认消息进行解扰，当所述HARQ确认消息被正确解扰时，则确定所述HARQ确认消息为目标HARQ确认消息。
其中，对接收到的HARQ确认消息进行解扰的具体实现方式可以为，基于所述组标识产生扰码序列，使用该扰码序列对接收到的G-DCI进行的负载(payload)的CRC进行解扰。当解扰后的CRC与根据G-DCI的负载计算获得CRC完全一致时，则认为所述HARQ确认消息被正确解扰。
本实施例，通过第一终端在第一GF资源上向网络设备发送第一数据，其中，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，网络设备向所述第一终端发送HARQ确认消息，第一终端使用第一GF资源组的组标识对所述HARQ确认消息进行解扰，当所述HARQ确认消息被正确解扰时，则确定所述HARQ确认消息为所述目标HARQ确认消息，所述目标HARQ确认消息与所述第一GF资源组对应，所述目标HARQ确认消息用于对在所述第一GF资源组的GF资源上传输的所有终端的数据进行确认，所述所有终端包括所述第一终端，所述所有终端的数据包括所述第一数据，实现通过目标HARQ确认消息对在GF资源组中的GF资源上传输的所有终端的数据进行确认，该GF资源上传输数据的终端可以包括一个或多个终端，即基于GF资源分组达到终端分组的目的，同组GF资源对应的终端映射至同一个HARQ确认消息进行数据传输的确认，从而可以减少相关信令开销。
并且，通过加扰、解扰的方式使得在不同GF资源组中的GF资源上传输数据的终端获取对应的目标HARQ确认消息，GF资源组的标识不必显式携带在HARQ确认消息中，可以进一步节省开销。
图5A为本申请的另一种数据传输的确认方法的流程图，图5B为本申请的另一种数据传输的确认方法的示意图，如图5A所示，本实施例通过在HARQ确认消息中显式携带组标识的方式实现接收和识别第一资源组对应的目标HARQ确认消息，本实施例的方法可以包括：
步骤301、第一终端在第一GF资源上向网络设备发送第一数据。
其中，第一GF资源属于第一GF资源组。
相应的，网络设备在第一GF资源上接收第一终端发送的第一数据。
其中，步骤301的具体解释说明可以参见上述图3所示实施例的步骤101，此处不再赘述。
步骤302、网络设备向第一终端发送HARQ确认消息。
具体的，网络设备根据一个或多个终端在第一GF资源组中的传输的数据的接收情况，该一个或多个终端传输的数据包括第一终端的第一数据，生成目标HARQ确认消息，即网络设备向一个或多个终端反馈通过第一GF资源组的GF资源传输的所有终端的数据的确认信息。其中，由于网络设备还可以对其他GF资源组的数据进行确认，所以，网络设备可以发送多个HARQ确认消息，每个HARQ确认消息对应一个GF资源组，网络设备可以在HARQ确认消息中携带组标识，以区分不同GF资源组的HARQ确认消息。其中一个HARQ确认消息即为携带第一GF资源组的组标识的目标HARQ确认消息(即第一GF资源组对应的HARQ确认消息)。
第一终端接收网络设备发送的HARQ确认消息，第一终端需要通过下述步骤303，以确定接收到的HARQ确认消息是否为自身的目标HARQ确认消息。
需要说明的是，该组标识也可以携带在承载HARQ确认消息的G-DCI中。
步骤303、所述第一终端判断所述HARQ确认消息是否包括所述第一GF资源组对应的组标识，当所述HARQ确认消息包括所述第一GF资源组对应的组标识时，则确定所述HARQ确认消息为目标HARQ确认消息。
所述目标HARQ确认消息与所述第一GF资源组对应。
即第一终端在接收到一个HARQ确认消息时，可以检查该HARQ确认消息是否携带第一GF资源组对应的组标识，当携带第一GF资源组对应的组标识时，确定该HARQ确认消息为目标HARQ确认消息，进而根据该目标HARQ确认消息确定第一数据的ACK/NACK信息。
可以理解的，另一种实现方式，第一终端在接收到一个G-DCI时，可以检查该G-DCI是否携带第一GF资源组对应的组标识，当携带第一GF资源组对应的组标识时，确定该G-DCI为自己期望的G-DCI，进而从该G-DCI中获取目标HARQ确认消息，根据该目标HARQ确认消息确定第一数据的ACK/NACK信息。
以图5B做举例说明，将GF资源1和GF资源2定义为GF资源组1，用G-ID1标识；GF资源3和GF资源4定义为GF资源组2，用G-ID2标识。网络设备在发送的与GF资源组1对应的G-DCI1中，显式携带G-ID1，表示G-DCI1是发送给在GF资源组1中的GF资源上传输数据的一个或多个终端的；网络设备在发送的与GF资源组2对应的G-DCI2中，显式携带G-ID2，表示G-DCI2是发送给在GF资源组2中的GF资源上传输数据的一个或多个终端的。
本实施例，通过第一终端在第一GF资源上向网络设备发送第一数据，其中，所述第一GF资源属于第一GF资源组，所述第一GF资源组包括N个GF资源，网络设备向所述第一终端发送HARQ确认消息，当该HARQ确认消息包括所述第一GF资源组的组标识时，则确定所述HARQ确认消息为目标HARQ确认消息，所述目标HARQ确认消息与所述第一GF资源组对应，所述目标HARQ确认消息用于对在所述第一GF资源组的GF资源上传输的所有终端的数据进行确认，所述所有终端包括所述第一终端，所述所有终端的数据包括所述第一数据，实现通过目标HARQ确认消息对在GF资源组中的GF资源上传输的所有终端的数据进行确认，该GF资源上传输数据的终端可以包括一个或多个终端，即基于GF资源分组达到终端分组的目的，同组GF资源对应的终端映射至同一个HARQ确认消息进行数据传输的确认，从而可以减少相关信令开销。
并且，通过显式携带组标识的方式使得在不同GF资源组中的GF资源上传输数据的终端获取对应的目标HARQ确认消息。
本申请实施例中，组标识用于区分不同的GF资源组，组标识具体可以包括组公共无线网络临时标识(Group common Radio Network Temporary Identity，G-RNTI)或者组公共标识(Group common Identity，G-ID)。当然可以理解的，该组标识还可以采用其他标识，此处不一一举例说明。
上述实施例中的组标识可以是网络设备配置给终端的，也可以是终端计算确定的。
具体的，一种可实现方式，组标识是网络设备配置给终端的。具体的，网络设备向第一终端发送第一配置信息，相应的，第一终端接收网络设备发送的第一配置信息，该第一配置信息包括所述第一GF资源组对应的组标识。
其中，举例而言，网络设备可以在为终端配置GF资源时，同时配置与该GF资源所属GF资源组对应的组标识。
该第一配置信息可以通过RRC信令、MAC CE或物理层信令等方式传输给终端。
另一种可实现方式，组标识是终端计算确定的。具体的，第一终端根据所述第一GF资源组所在时域资源的索引和/或频域资源的索引确定所述第一GF资源组对应的组标识。其中，所述时域资源包括子帧或时隙或微时隙，所述频域资源包括子载波或资源块。
具体的，该第一GF资源组所在时频资源可以包括一个或多个子帧/时隙/微时隙。当该第一GF资源组所在时频资源包括一个子帧/时隙/微时隙时，第一终端可以根据该第一GF资源组所在时频资源的子帧/时隙/微时隙的索引计算该第一GF资源组对应的组标识。当该第一GF资源组所在时频资源包括多个子帧/时隙/微时隙时，第一终端可以根据该第一GF资源组所在时频资源中的特定子帧/时隙/微时隙的索引计算该第一GF资源组对应的组标识，举例而言，采用多个子帧/时隙/微时隙中的第一个子帧/时隙/微时隙的索引计算该第一GF资源组对应的组标识。
可以理解的，在确定该第一GF资源组对应的组标识的过程中，还可以考虑其他因素，如当前系统帧号等。
举例而言，图6为本申请的组标识计算的示意图，如图6所示的传统TDD配置0，其中每个方格代表一个子帧，子帧U3和U4的HARQ确认消息都在子帧D0中传输，以U3和U4中均配置了GF资源为例进行举例说明，且每个UL子帧中的GF资源定义为一个GF资源组，则不同UL子帧的GF资源映射到D0中的不同G-DCI。进而，网络设备可通过子帧号隐式向终端指示组标识(G-RNTI/G-ID)。例如，当终端被配置了U3中的GF资源，且在U3中的GF资源上传输了数据，则终端在D0中对应的G-DCI的组标识(G-RNTI/G-ID)根据子帧U3的子帧号来计算获得。由于不同子帧的子帧号不同，根据子帧号计算得到的不同子帧对应的G-DCI的组标识(G-RNTI/G-ID)也是不同的。假设GF资源所在子帧的子帧号为z，则该子帧中的GF资源组对应G-DCI的组标识(G-RNTI/G-ID)为h(z)，h为函数。除了子帧号之外，组标识(G-RNTI/G-ID)的计算中还可考虑其它因素，如当前系统帧号。假设当前系统帧号为s，GF资源所在子帧的子帧号为z，则对应G-DCI的组标识(G-RNTI/G-ID)为h(z,s)。函数h可以根据需求进行灵活设置，此处不一一举例说明。
终端根据GF资源所在子帧/时隙/微时隙的索引计算对应的组标识的方式，可以进一步节省网络配置开销。
图7为本申请的另一种数据传输的确认方法的流程图，如图7所示，本实施例在上述任一实施例的基础上，本实施例的方法还可以包括：
步骤401、网络设备向第一终端发送第二配置信息。
相应的，第一终端接收网络设备发送的第二配置信息。
其中，所述第二配置信息包括所述第一终端在位表中的位置索引，所述目标HARQ确认消息包括所述位表(bitmap)，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
具体的，目标HARQ确认消息用于对在第一GF资源组的GF资源上传输的所有终端的数据进行确认，该目标HARQ确认消息中一个或多个比特位与该第一终端的第一数据对应，该第二配置信息用于向第一终端指示第一数据的确认信息在目标HARQ确认消息中的位置。
步骤402、第一终端根据所述第二配置信息获取第一数据的确认信息。
具体的，第一终端通过上述实施例获取目标HARQ确认消息后，第一终端根据第二配置信息获取第一终端在位表中的位置索引，根据该位置索引获取第一数据的确认信息。
举例而言，网络设备将第一终端配置在GF资源1中，且配置该第一终端在位表中的位置索引为k，则第一终端在GF资源1中发送数据之后，接收到目标HARQ确认消息，根据目标HARQ确认消息的bitmap的第k位确定网络设备是否正确接收该第一数据。例如，Bitmap的第k位为1，表示网络设备正确接收该第一数据，否则，表示网络设备未正确接收该第一数据。
本实施例，通过网络设备向第一终端发送第二配置信息，该第二配置信息包括所述第一终端在位表中的位置索引，所述目标HARQ确认消息包括所述位表(bitmap)，第一终端根据所述第二配置信息获取第一数据的确认信息，从而确定网络设备是否正确接收该第一数据。
图8A为本申请的另一种数据传输的确认方法的流程图，图8B为本申请的另一种数据传输的确认方法的示意图，如图8A所示，本实施例在上述任一实施例的基础上，本实施例的方法还可以包括：
步骤501、网络设备向第一终端发送第三配置信息。
相应的，第一终端接收网络设备发送的第三配置信息。
所述第三配置信息包括所述第一终端在所述第一GF资源中的解调参考信号(Demodulation Reference Signal，DMRS)索引，所述DMRS索引所指示的DMRS用于所述第一数据的传输。
具体的，上述第三配置信息用于隐式指示终端在位表(Bitmap)中的位置索引。网络设备在为终端配置GF资源时，还为同一GF资源中的不同终端配置了不同的DMRS，即在一个GF资源中，网络设备部通过接收到的数据的DMRS来识别该数据发送方的身份(即终端标识)，这种情况下，网络设备为终端配置的DMRS的索引即为终端的身份标识，即UE ID。不同GF资源复用相同DMRS，即不同GF资源中的UE ID可以是复用 的。例如，GF资源1中UE ID为1-12，GF资源2中UE ID也是1-12。
步骤502、所述第一终端根据所述DMRS索引确定所述第一终端在位表中的位置索引。
所述目标HARQ确认消息包括所述位表，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
具体的，目标HARQ确认消息用于对在第一GF资源组的GF资源上传输的所有终端的数据进行确认，该目标HARQ确认消息中一个比特位与该第一终端的第一数据对应，该第三配置信息用于向第一终端指示第一数据的确认信息在目标HARQ确认消息中的位置。
如图8B所示，N＝1，即网络设备配置或标准预定义每个GF资源映射到一个G-DCI，且两者之间一一对应。这种情况下，可以利用UE ID来隐式指示第一终端在G-DCI中的Bitmap中的位置索引。假设第一终端在GF资源中的UE ID为u，对应位置索引为k，则k＝f(u)，f为映射函数。一种简单的映射方法是，UE ID即为位置索引，即f(u)＝u。如8B所示，GF资源1和GF资源2分别映射到G-DCI1和G-DCI2，每个GF资源可容纳12个UE(通过DMRS区分同一GF资源中的不同UE)，每个G-DCI中的Bitmap长度为12，则GF资源1中UE ID为1、2、…、12的UE分别与G-DCI1中Bitmap的第1、第2、…、第12位相对应。
步骤503、第一终端根据所述位置索引获取第一数据的确认信息。
具体的，第一终端通过上述实施例获取目标HARQ确认消息后，第一终端根据第三配置信息确定第一终端在位表中的位置索引，根据该位置索引获取第一数据的确认信息。
举例而言，第一终端根据第三配置信息确定该位置索引位2，则第一终端在GF资源1中发送数据之后，接收到目标HARQ确认消息，根据目标HARQ确认消息的bitmap的第2位确定网络设备是否正确接收该第一数据。例如，Bitmap的第2位为1，表示网络设备正确接收该第一数据，否则，表示网络设备未正确接收该第一数据。
本实施例，通过网络设备向第一终端发送第三配置信息，该第三配置信息包括所述第一终端在所述第一GF资源中的解调参考信号(DMRS)索引，第一终端根据所述第三配置信息确定第一终端在位表中的位置索引，根据该位置索引获取第一数据的确认信息，从而确定网络设备是否正确接收该第一数据。
图9为本申请的另一种数据传输的确认方法的流程图，如图9所示，本实施例在上述任一实施例的基础上，本实施例的方法还可以包括：
步骤601、网络设备向第一终端发送第四配置信息。
相应的，第一终端接收网络设备发送的第四配置信息。
所述第四配置信息包括所述第一GF资源的资源索引和所述第一终端在所述第一GF资源中的DMRS索引，所述资源索引是所述第一GF资源在所述第一GF资源组中的排序，所述DMRS索引所指示的DMRS用于所述第一数据的传输。
具体的，对于GF资源的N≥2，即网络设备配置或标准预定义至少两个GF资源映射到一个G-DCI，即映射到一个HARQ确认消息。这种情况下，网络设备在为终端配置一个GF资源时，不仅需要配置终端在此GF资源中的DMRS(即对应UE ID)，还需指 示该GF资源在GF资源组中的排序，即该GF资源是其所在GF资源组中的第几个GF资源。GF资源在GF资源组中的排序可称为GF资源索引。
步骤602、所述第一终端根据所述资源索引和所述DMRS索引确定所述第一终端在位表中的位置索引。
所述目标HARQ确认消息包括所述位表，所述位表中的所述位置索引对应的值表示所述第一数据的确认信息。
具体的，目标HARQ确认消息用于对在第一GF资源组的GF资源上传输的所有终端的数据进行确认，该目标HARQ确认消息中一个或多个比特位与该第一终端的第一数据对应，该第四配置信息用于向第一终端指示第一数据的确认信息在目标HARQ确认消息中的位置。
具体的，第一终端基于网络设备配置的DMRS索引以及资源索引，即可确定自身在目标HARQ确认消息的Bitmap中对应的位置索引。举例而言，资源索引为n，第一终端在该GF资源中的UE ID为u，则该UE在Bitmap中对应的位置索引为k＝g(u,n)，g为映射函数。
进一步举例说明，假设GF资源0-GF资源N-1共N个GF资源(GF资源索引分别为0-N-1)为一个GF资源组且映射到G-DCI1，每个GF资源可容纳M个终端(通过DMRS区分同一GF资源中的不同终端)，G-DCI1中的Bitmap长度为M×N，其中各比特的位置索引分别为0-M×N-1。对于UE1，网络设备配置其在GF资源n(0≤n≤N-1)中的UE ID为m(0≤m≤M-1)，则该UE1在G-DCI的Bitmap中对应的比特的位置索引k＝n×M+m。
步骤603、第一终端根据所述位置索引获取第一数据的确认信息。
具体的，第一终端通过上述实施例获取目标HARQ确认消息后，第一终端根据第四配置信息确定第一终端在位表中的位置索引，根据该位置索引获取第一数据的确认信息，确定网络设备是否正确接收该第一数据。
需要说明的是，本实施例中同一UE在一个目标HARQ确认消息的Bitmap中可以有多个对应比特，这种情况下发生在下述任一情况下或多种情况同时出现时：
情况1：网络设备配置UE在同一GF资源组的不同GF资源中传输不同传输块(Transmission Block，TB)的数据，即传输不同HARQ进程的数据。举例而言，网络设备配置UE1可在GF资源1和GF资源2中传输不同HARQ进程的数据，即UE1可在GF资源1和GF资源2中传输不同TB的数据，这两个TB的数据在目标HARQ确认消息的Bitmap中各对应一个比特。
情况2：网络设备配置UE在同一GF资源中采用多层流传输。例如，网络设备配置UE可以在GF资源中采用W层流传输(即UE采用MIMO传输)，每层流对应一个TB，则该W个TB的数据在目标HARQ确认消息的Bitmap中对应W个比特，每比特对应一个TB；
情况3：网络设备配置UE采用基于码块组(Code Block Group，CBG)的传输。例如，网络设备配置UE将每个TB划分为V个CBG进行传输，UE需对每个CBG进行HARQ确认，这种情况下，UE发送的每个TB需在目标HARQ确认消息的Bitmap中对应V个比特，每比特对应一个CBG。
其中，对于情况1，网络设备需配置UE对应的多个GF资源，以及其在每个GF资源中对应的位置索引(显式或隐式配置)。
对于情况2或情况3，网络设备只需配置UE对应的多个比特的第一个比特的位置索引即可。例如，对于情况2，基站配置UE在Bitmap中对应的第一个比特的位置索引为k，则k-k+W-1即为该UE对应的W个比特；对于情况3，基站配置UE对应的第一个比特的位置索引为k，则k-k+V-1即为该UE对应的V个比特。
对于情况1-情况3中任意两种或三种情况同时出现的情况，根据上述方法类推即可，具体不再赘述。例如，对于情况1和情况2同时出现的情况，网络设备需配置UE对应的多个GF资源，以及其在每个GF资源中对应的第一个比特的位置索引(显式或隐式配置)。对于其中某个GF资源，假设网络设备配置UE在Bitmap中对应的第一个比特的位置索引为k，则k-k+W-1即为该UE在该GF传输的数据对应的W个比特。
本实施例，通过网络设备向第一终端发送第四配置信息，该第四配置信息包括所述第一GF资源的资源索引和所述第一终端在所述第一GF资源中的DMRS索引，第一终端根据所述第四配置信息确定第一终端在位表中的位置索引，根据该位置索引获取第一数据的确认信息，从而确定网络设备是否正确接收该第一数据。
需要说明的是，本申请实施例中在给定N的情况下，且每个GF资源能容纳的UE个数上限确定时，本申请的HARQ确认消息中Bitmap长度上限确定，因此可以使得承载该HARQ确认消息的G-DCI长度固定，从而可以减少UE在接收G-DCI时的盲检次数，使UE更加省电。
可以理解的是，上述各个实施例中，由第一终端实现的方法或步骤，也可以是由第一终端内部的芯片实现的。由网络设备实现的方法或者步骤，也可以是由网络设备内部的芯片实现的。
