Description

一种混合自动重传请求HARQ反馈方法及装置
本申请要求于2017年8月11日提交中国专利局、申请号为201710687835.2、申请名称为“一种混合自动重传请求HARQ反馈方法及设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信技术领域，尤其涉及一种混合自动重传请求HARQ反馈方法及装置。
背景技术
在下一代无线接入系统(Next generation RAT，NR)中，由于混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)定时关系是可以动态配置的。作为一种示例，终端设备在第n个时隙接收到由网络设备发送的下行数据包，在第n个时隙之后的第4个时隙反馈HARQ反馈信息，而终端设备在第n+1个时隙接收到由网络设备发送的下行数据包，可能会在第n+1个时隙之后的第3个时隙反馈HARQ反馈信息。
当网络设备为终端设备分配多个服务小区，多个服务小区中每个服务小区分别对应不同的分量载波(Component Carrier，CC)，以CC0、CC1、CC3为例，每个分量载波对应不同的物理下行共享信道(Physical Downlink Share Channel，PDSCH)，在终端设备接收到由每个PDSCH发送的下行数据包时，则对应的需要反馈至少一个确认/非确认(Acknowledgement/Not-acknowledgement，ACK/NACK)信息，正是由于上述HARQ定时关系是可以动态配置的，会导致不同分量载波在不同时刻的PDSCH对应的ACK/NACK信息会在同一物理上行控制信道(Physical Uplink Control Channel，PUCCH)发送。在这种情况下，为了使网络设备能够识别终端设备的反馈信息，网络设备和终端设备之间至少要确定终端设备反馈的比特数。
但是在现有技术中，网络设备和终端设备确定反馈的比特数，针对的场景都是具有相同时隙长度的分量载波。然而在NR系统中，不同分量载波的时隙长度可能是不相同的。因此，现有技术中针对相同时隙长度的反馈方案不再适用于类似NR系统中的具有不同时隙长度的分量载波的场景。
发明内容
本申请提供一种混合自动重传请求HARQ反馈方法及装置，用于提高终端设备反馈HARQ反馈信息的反馈精度。
第一方面，本申请实施例提供了一种混合自动重传请求HARQ反馈方法，该方法可由网络设备执行，网络设备例如为基站。该方法包括网络设备获取用于指示终端设备反馈HARQ反馈信息的第一指示信息，所述第一指示信息是根据参考时隙和至少一个第一时隙上的与数据信道对应的信息数量和/或与控制信道对应的信息数量得到的，所述参考时隙和所述至少一个第一时隙分别在所述终端被调度的多个分量载波中的不同的分量载波上，所述参考时隙与所述至少一个第一时隙的起始时刻相同；其中，所述多个分量载波中至少有两个分量载波的时隙长度不同；所述网络设备向所述终端设备发送至少用于指示所述第一 指示信息的指示信息。所述终端设备可以获取至少用于指示所述第一指示信息的指示信息，并根据指示信息，向所述终端设备发送HARQ反馈信息。
本申请实施例中，在多个分量载波中存在至少两个分量载波的时隙长度不同时，网络设备根据参考时隙和与参考时隙的起始时刻相同的至少一个第一时隙上的与数据信道对应的信息数量和/或与控制信道对应的信息数量得到第一指示信息，以使终端设备能够根据第一指示信息确定HARQ反馈信息，使得本申请实施例提供的技术方案能适用于类似于5G这种具有不同的时隙长度的分量载波的网络。
在一个可能的设计中，当从聚合窗的起始时刻开始累积有多个参考时隙时，所述第一指示信息为所述参考时隙和所述至少一个第一时隙上的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量，以及所述多个分量载波在所述参考时隙之前的时隙上的与所述数据信道对应信息数量和/或与所述控制信道对应信息数量；其中，所述聚合窗为在同一上行控制信道或者同一上行控制信息反馈HARQ反馈信息的下行时隙的集合。
在本申请实施例中，在从聚合窗的起始时刻开始累积有多个参考时隙时，第一指示信息还包括在时域上的与数据信道对应的信息数量和/或与控制信道对应的信息数量的累计。其中，该步骤还可以表述为当从聚合窗的起始时刻开始累积有多个参考时隙时，所述第一指示信息为所述参考时隙中的每个参考时隙和对应的所述至少一个第一时隙上的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量。

在本申请实施例中，网络设备还获取用于指示终端设备反馈HARQ反馈信息的第二指示信息，以使终端设备能够利用第一指示信息和第二指示信息确定HARQ反馈信息，确定HARQ反馈信息的反馈顺序和反馈比特数，从而提高终端设备的反馈精度。其中，具体时刻例如是聚合窗的起始时刻。
在一个可能的设计中，所述网络设备向所述终端设备发送至少用于指示所述第一指示信息的指示信息，包括：所述网络设备在所述聚合窗内的调度时隙和/或专用时隙向所述终端设备发送用于指示所述第一指示信息和/或所述第二指示信息的指示信息；和/或所述网络设备在所述聚合窗外的时隙向所述终端设备发送用于指示所述第一指示信息的指示信息。
在本申请实施例中，基站可以通过多种方式向终端设备反馈至少用于指示第一指示信息的指示信息。其中，网络设备在聚合窗内的调度时隙和/或向终端设备发送用于指示第一指示信息和第二指示信息的指示信息时，能够使终端精确确定出反馈HARQ反馈信息的顺序以及反馈比特数；网络设备在聚合窗内的调度时隙和/或专用时隙向终端设备发送用于指示第一指示信息和第二指示信息的指示信息，在聚合窗外发送用于指示第一指示信息的指示信息，由于多次向终端设备发送用于指示第一指示信息的指示信息，从而能够提高网络设备发送第一指示信息的可靠性，从而能够进一步提高终端反馈HARQ反馈信息的精确度。网络设备也可以在聚合窗外向终端设备发送用于指示第一指示信息的指示信息，或者在其它时刻向终端设备发送至少用于指示第一指示信息的指示信息，在本申请实施例中不 作限制。

在本申请实施例中，当针对整个聚合窗的第一指示信息的发送次数小于预设值时，网络设备在聚合窗外发送用于指示针对整个聚合窗的第一指示信息的指示信息，这样通过多次向终端设备发送用于指示第一指示信息的指示信息，能够提高发送用于指示第一指示信息的指示信息的可靠性。
在一个可能的设计中，所述网络设备在所述聚合窗外的时隙向所述终端设备发送用于指示所述第一指示信息的指示信息，包括：所述网络设备在所述聚合窗外的指定时隙向所述终端设备发送用于指示针对整个聚合窗的第一指示信息的指示信息。

在本申请实施例中，网络设备在不同时隙向终端设备发送的指示信息所包括的具体内容并不相同，以上只是几种举例，在本申请实施例中不作限制。
在本申请实施例中，当网络设备发送的第一指示信息为所述针对聚合窗的指示信息时，终端设备能够根据针对聚合窗的指示信息确定HARQ反馈信息；当网络设备发送的第一指示信息为针对特定时隙的指示信息时，终端设备就能够根据针对指定时隙的指示信息确定HARQ反馈信息。
在一个可能的设计中，所述网络设备通过DCI向所述终端设备发送所述指示信息；其中，所述DCI具有特定格式或具有特定频域信息，以指示所述终端设备所述DCI中携带所述第一指示信息；或所述网络设备通过PDSCH向所述终端设备发送所述指示信息，且利用DCI指示所述终端设备所述PDSCH中携带有所述第一指示信息；或所述网络设备通过 DCI向所述终端设备发送所述指示信息；其中，所述指示信息中包括所述第一指示信息，以及所述聚合窗的信息；或在所述网络设备在聚合窗内的调度时隙和或专用时隙向所述终端设备发送用于指示所述第一指示信息和或所述第二指示信息的指示信息时，所述方法还包括：所述网络设备在所述聚合窗内，通过所述多个分量载波中至少一个分量载波重复发送用于指示所述第一指示信息的指示信息，和/或通过参考时隙的分量载波中的不同时隙重复发送用于指示所述第一指示信息的指示信息。
在本申请实施例中，网络设备发送用于指示第一指示信息的指示信息的发送的方式可能有不同方式，且以上只是几种举例。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
本申请实施例中描述的技术方案可用于第五代移动通信技术(5G)，还可用于下一代移动通信系统。
以下，对本申请实施例中的部分用语进行解释，以便于本领域技术人员理解。
(1)网络设备，例如包括基站(例如，接入点)，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设备通信的设备。基站可用于将收到的空中帧与IP分组进行相互转换，作为终端设备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IP网络。基站还可协调对空中接口的属性管理。例如，基站可以包括长期演进(Long Term Evolution，LTE)系统或演进的LTE系统(LTE-Advanced，LTE-A)中的演进型基站(NodeB或eNB或e-NodeB，evolutional Node B)，或者也可以包括5G系统中的下一代节点B(next generation node B，gNB)，本申请实施例并不限定。
(2)终端设备，包括向用户提供语音和/或数据连通性的设备，例如可以包括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处理设备。该终端设备可以经无线接入网(Radio Access Network，RAN)与核心网进行通信，与RAN交换语音和/或数据。该终端设备可以包括用户设备(User Equipment，UE)、无线终端设备、移动终端设备、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)、接入点(Access Point，AP)、远程终端设备(Remote Terminal)、接入终端设备(Access Terminal)、用户终端设备(User Terminal)、用户代理(User Agent)、或用户装备(User Device)等。例如，可以包括移动电话(或称为“蜂窝”电话)，具有移动终端设备的计算机，便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，智能穿戴式设备等。例如，个人通信业务(Personal Communication Service，PCS)电 话、无绳电话、会话发起协议(SIP)话机、无线本地环路(Wireless Local Loop，WLL)站、个人数字助理(Personal Digital Assistant，PDA)、智能手表、智能头盔、智能眼镜、智能手环、等设备。还包括受限设备，例如功耗较低的设备，或存储能力有限的设备，或计算能力有限的设备等。例如包括条码、射频识别(RFID)、传感器、全球定位系统(GPS)、激光扫描器等信息传感设备。
(3)CC，通过聚合多个CC来得到更大的工作带宽，也就是载波聚合(Carrier Aggregation，CA)，构成通信系统的下行和上行链路，从而支持更高的传输速率。例如为了支持100兆赫兹(MHz)的带宽，可以通过聚合5个20MHz的CC来得到。这里，每个CC称为一个小区(Cell)。对一个UE，基站可以配置在多个CC中工作，其中一个是主CC(Pcell)，其它CC称为辅CC(Scell)。在本申请实施例中，CC还可以是指一个载波、一个载波的子载波、或者是带宽部分(Band Width Part，BWP)。
(4)本申请实施例中的术语“系统”和“网络”可被互换使用。“多个”是指两个或两个以上，鉴于此，本申请实施例中也可以将“多个”理解为“至少两个”。“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，同时存在A和B，单独存在B这三种情况。另外，字符“/”，如无特殊说明，一般表示前后关联对象是一种“或”的关系。
由于HARQ定时关系是可以动态配置的，导致不同分量载波在不同时刻的PDSCH对应的ACK/NACK信息会在同一PUCCH上发送。在这种情况下，为了使网络设备能够识别终端设备的反馈信息，网络设备和终端设备之间至少要确定终端设备反馈的比特数。
作为一个示例，由于网络设备能够计算出调用的CC在当前时隙能够传输的TB数量，以及在每个CC在当前时隙上传输的TB数量，所以，网络设备能够计算出在当前时隙及当前时隙之前的时隙所有CC累计的TB数量，记为第一指示信息，以及，截止到当前CC，在当前时隙及当前时隙之前的时隙所累积的TB数量，记为第二指示信息。然后网络设备在向终端设备发送的下行控制信息(Downlink Control information，DCI)中携带第一指示信息和第二指示信息，以使终端设备在接收到DCI信息后，则根据DCI信息中的第一指示信息和第二指示信息来确定ACK/NACK的反馈顺序及反馈的比特数。其中，当前时隙为网络设备向终端发送TB的时隙，当前载波为网络设备在当前时隙调度的分量载波。
假设终端设备激活8个CC，记为CC0-CC7，每个CC包括4个时隙，记为时隙n-时隙n+3(也就是Slot n-Slot n+3)，每个时隙传输一个TB。请参见图1，CC0的Slot n位置处的(1/3)表示在CC0-CC7的Slot n上能够传输3个TB，CC0的Slot n传输1个TB；在CC2的Slot n位置处的(2/3)表示，在CC0-CC7的Slot n时隙上能够传输3个TB，在CC0的Slot n上传输1个TB，累计CC1在Slot n上传输1个TB，共为2个TB；在CC5的Slot n位置处的(3/3)表示，在CC0-CC7的Slot n时隙上能够传输3个TB，在CC5的Slot n上传输1个TB，累计CC0和CC2在Slot传输的2个TB，共3个TB；在CC0的Slot n+1位置处(4/6)表示，在CC0-CC7的Slot n+1时隙上能够传输3个TB，累计在CC0-CC7的Slot n时隙上传输的3个TB，共6个TB，在CC0的Slot n+1上传输1个TB，累计CC0、CC2、CC5在Slot n上传输的3个TB，共4个TB，以此类推，在此不再赘述。
由于，网络设备在不同分量载波的相同时隙上发送下行控制信息(Downlink Control Information，DCI)，例如网络设备在不同分量载波对应的Slot n的前1-3个正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)上向CC0-CC7发送DCI，记为DCI0、 DCI2、DCI5，这样，在终端设备在Slot n时隙接收到DCI之后，便能够确定网络设备在Slot n上共传输3个TB，在CC0上传输一个TB、在CC2上传输一个TB、在CC5上传输一个TB，从而能够确定反馈HARQ反馈信息的反馈顺序和总的比特数。
上述技术方案中针对的是时隙长度都是相同CC，继续参考图1，图1中所示的CC0-CC7中每个CC包括的时隙长度相同，不同CC的时隙长度也相同。然而在NR系统中，为了满足不同的业务需求，多个分量载波的时隙长度可能不相同。请参见图2，终端设备对应n个分量载波，记为CC0-CCn中，CC0、CC1的时隙长度相同，CC2、CCn与CC0、CC1的时隙长度不同，在这种情况下，现有技术中针对相同时隙长度的HARQ反馈方案不再适用于类似NR系统中的具有不同时隙长度的分量载波的场景。
鉴于此，本申请实施例给出一种混合自动重传请求HARQ反馈方法，在多个分量载波中存在至少两个分量载波的时隙长度不同时，网络设备根据参考时隙和与参考时隙的起始时刻相同的至少一个第一时隙上的与数据信道对应的信息数量和/或与控制信道对应的信息数量得到第一指示信息，以使终端设备能够根据第一指示信息确定反馈HARQ反馈信息的比特数，使得本申请实施例提供的技术方案能适用于类似于5G系统的这种不同分量载波具有不同的时隙长度的网络。
请参见图3，为本申请实施例的一种应用场景。在图3包括基站和位于该基站的覆盖范围内的终端设备。基站为终端设备分配多个小区，多个小区中的每个小区对应一个CC，例如以3个小区为例，分别为C0、C1、C2，与3个小区对应的CC分别为CC0、CC1、CC2。
基站通过PDSCH向终端设备发送传输块TB，TB可以通过多个CC发送。终端设备接收基站通过多个CC发送的TB，并向基站反馈与TB对应的ACK/NACK信息。
下面结合附图介绍本申请实施例提供的技术方案，在下面的介绍过程中，以本申请提供的技术方案应用在图3所示的应用场景中为例，且以网络设备是基站为例。
请参见图4，本申请实施例提供一种混合自动重传请求HARQ反馈方法，该方法的流程描述如下：
S401：基站获取用于指示终端设备反馈HARQ反馈信息的第一指示信息，第一指示信息是根据参考时隙和至少一个第一时隙上的与数据信道对应的信息数量和/或与控制信道对应的信息数量得到的，参考时隙和至少一个第一时隙分别在终端调度或被调度的多个分量载波中的不同的分量载波上，参考时隙与至少一个第一时隙的起始时刻相同；其中，多个分量载波中至少有两个分量载波的时隙长度不同；
本申请实施例提供的一种混合自动重传请求HARQ反馈方法可以适用于下行反馈，也就是终端设备对基站发送信息的反馈，也可以适用于上行反馈，也就是基站对终端设备发送信息的反馈。在下面的介绍中，以下行反馈为例。
请参见图5，终端设备被服务的分量载波，也可以是被调度或激活的分量载波，记为CC0-CCn，每个分量载波包括不同数量的时隙。图5中从第一个TB至UL这一段内CC0-CCn上所有时隙的集合称为为聚合窗，该聚合窗内的各个时隙的HARQ反馈信息在同一上行控制信道或同一上行控制信息上反馈。此处，聚合窗可以是频域上的聚合、或在时域上的聚合、或在频域和时域上的聚合，其中，频域可以是指多个CC，或者多个BWP。且此处对于“聚合窗”的名称不作限制，也可以是“绑定窗”。
继续参考图5，图5中所示的CC0、CC1和CCn的时隙长度均不相同，本申请实施例 中的分量载波的时隙长度不同，也可以理解为两个分量载波的OFDM参数集合，即OFDM的基本参数numerology不同，或者子载波间隔(Subcarrier Spacing)不同。
在CC0、CC1、CCn的时隙长度均不相同的情况下，如何确定第一指示信息和第二指示信息，首先需要确定一个参考时隙。
本申请实施例中，参考时隙可以为多个分量载波中时隙长度最短的时隙，例如图5中所示的CC1的时隙；参考时隙也可以为多个分量载波中时隙长度最长的时隙，例如图5中所示的CCn的时隙；参考时隙也可以为由协议规定或者由所述基站配置给终端设备的所述多个载波分量中指定的时隙，例如图5所示的CC0的时隙，其中，基站的配置方式可以是通过无线资源控制(Radio Resource Control，RRC)配置、或通过物理下行控制信道配置、或RRC层配置了参数集合，由媒体访问控制(Media Access Control，MAC)层或物理层从参数集合中配置一个给终端设备。在具体实现过程中，基站可以只配置一种参考时隙，也可以配置多种参考时隙，例如为多个分量载波中时隙长度最短的时隙、多个分量载波中时隙长度最长的时隙、由协议规定或者由基站配置给终端设备的。在基站配置多种不同参考时隙的情况下，可以根据实际情况选择使用其中的一种。
以CC1的时隙作为参考时隙，从聚合窗的起始时刻起累计的参考时隙有多个，例如图5中所示的15个。当参考时隙有多个时，所述第一指示信息为所述参考时隙和所述至少一个第一时隙上的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量，以及所述多个分量载波在所述参考时隙之前的时隙上的与所述数据信道对应信息数量和/或与所述控制信道对应信息数量。
在本申请实施例中，基站还需要获取用于指示终端设备反馈HARQ反馈信息的第二指示信息信息，其中，基站可以在获取第一指示信息的同时，获取用于指示终端设备反馈HARQ反馈信息的第二指示信息，基站也可以在获取第一指示信息之前获取第二指示信息，也可以在获取第一指示信息之后获取第二指示信息，在此对于第一指示信息和第二指示信息的获取顺序不作限制。其中，第二指示信息是从所述聚合窗的具体时刻和所述多个分量载波中的第一个分量载波，频域为先的方式累计到第二时隙的当前分量载波的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量得到的；其中，所述第二时隙为从所述参考时隙和所述至少一个第一时隙中得到的。此处的具体时刻例如聚合窗的起始时刻。
在本申请实施例中，数据信道上的信息数量为传输块TB数量、码块组CBG数量、TB和CBG数量、物理下行共享信道PDSCH的下行控制信息DCI数量、或物理下行共享信道PDSCH的服务小区的数量中的至少一种；控制信道上的信息数量为指示下行半静态调度SPS释放的物理下行控制信道PDCCH数量、指示下行SPS激活的PDCCH数量、指示下行SPS释放的物理下行控制信道DCI数量、或指示下行SPS激活的DCI数量中的至少一种。
在基站发送的信息不同时，第一指示信息所包括的内容也不相同，下面分别介绍。
(1)、基站通过数据信道发送数据信息，则第一指示信息为根据参考时隙和至少一个第一时隙上的TB数量得到的；或第一指示信息为根据参考时隙和至少一个第一时隙上的CBG数量得到的；或第一指示信息为根据参考时隙和至少一个第一时隙上的TB和CBG数量得到；
(2)基站通过控制信道发送控制信息，则第一指示信息为根据参考时隙和至少一个 第一时隙上的下行指示SPS释放PDCCH数量、指示下行SPS激活PDCCH数量、指示下行SPS释放的物理下行控制信道DCI数量、或指示下行SPS激活的DCI数量；
(3)、基站通过数据信道发送数据信息，同时通过控制信道发送控制信息，则第一指示信息为根据参考时隙和至少一个第一时隙上的TB、CBG、以及指示下行SPS释放的物理下行控制信道和指示下行SPS激活的PDCCH数量得到的；或第一指示信息为根据参考时隙和至少一个第一时隙上的PDSCH的DCI数量、以及指示下行SPS释放的PDCCH或指示下行SPS激活的PDCCH数量得到的。
下面以与数据信道对应的信息数量为TB和CBG数量，参考时隙为多个分量载波中时隙长度最短和参考时隙为不是时隙长度最短这两种来介绍获取第一指示信息和第二指示信息的过程。
请参见图6，终端设备激活CC0-CCn个分量载波，其中，CC0、CC1和CCn具有不同的时隙长度，CC1的时隙长度最短，则以CC1的时隙作为参考时隙。其中，假设CC0的一个时隙传输一个TB、CC1的一个时隙传输两个CBG、CCn的一个时隙传输一个TB。
在本申请实施例中，在获取第一指示信息和第二指示信息的过程中，可能存在与参考时隙的起始时刻相同的至少一个第一时隙，也可能不存在与参考时隙的起始时刻相同的至少一个第一时隙，在不存在与参考时隙的起始时刻相同的至少一个第一时隙时，至少一个第一时隙上的与数据信道对应的信息数量和/或与控制信道对应的信息数量为0。例如以CC1的第一个时隙作为参考时隙，与CC1的第一个时隙的起始时刻相同的至少一个第一时隙为CC0的第一个时隙和CCn的第一个时隙，而当以CC1的第二个时隙为参考时隙，则不存在与CC1的第二个时隙的起始时刻相同的至少一个第一时隙。
相应的，当参考时隙有多个时，所述第一指示信息为所述参考时隙和所述至少一个第一时隙上的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量，以及所述多个分量载波在所述参考时隙之前的时隙上的与所述数据信道对应信息数量和/或与所述控制信道对应信息数量，还可以表述为当从聚合窗的起始时刻开始累积有多个参考时隙时，所述第一指示信息为所述参考时隙中的每个参考时隙和对应的所述至少一个第一时隙上的与所述数据信道对应的信息数量和/或与所述控制信道对应的信息数量。例如从聚合窗的开始时刻累计的参考时隙有3个，也就是将第一个参考时隙和与第一个参考时隙对应的至少一个第一时隙上与控制信道对应的信息数量和/或与控制信道数量对应的信息数量、第二个参考时隙和与第二个参考时隙对应的至少一个第一时隙上与控制信道对应的信息数量和/或与控制信道数量对应的信息数量、及第三个参考时隙和与第三个参考时隙对应的至少一个第一时隙上与控制信道对应的信息数量和/或与控制信道数量对应的信息数量进行相加。
第一，参考时隙为多个分量载波中时隙长度最短的时隙。
第一指示信息为参考时隙、至少一个第一参考时隙上的TB和CBG数量之和，以及在参考时隙之前的时隙累计的TB和CBG数量，例如以CC1的第一个时隙作为参考时隙，与CC1的第一个时隙的起始时刻相同的至少一个第一时隙为CC0的第一个时隙和CCn的第一个时隙，对应的第一指示信息为CC0的第一个时隙上的TB数量1+CC1的第一个时隙上的CBG数量2+CCn的第一个时隙上的TB数量1，总和为4。
在CC1的第二个时隙上，以CC1的第二个时隙为参考时隙，与CC1的第二个时隙的起始时刻相同的至少一个第一时隙为CC0的第一个时隙和CCn的第一个时隙，而CC0的 第一个时隙上的TB数量和CCn的第一个时隙上的CBG数量在CC1的第一个时隙上已经被统计过，所以，在CC1的第二个时隙对应的第一指示信息为CC1在第二个时隙上的CBG数量2+CC1在第一个时隙上累计的TB数量和CBG数量4，总和为6。
按照上述计算方法，基站能够获得在CC1上的每个时隙对应的第一指示信息，在此不再赘述。
第二指示信息为从所述聚合窗的起始时刻和所述多个分量载波中的第一个分量载波，频域为先的方式累计到第二时隙的当前分量载波的TB数量和CBG数量得到的，此处，第一个分量载波可以是索引值最小的分量载波，第二时隙为CC1上的各个时隙，或是CC0、CCn上与CC1上各时隙的起始时刻相同的时隙。例如仍以CC1的第一个时隙作为参考时隙，与CC1的第一个时隙的起始时刻相同的至少一个第一时隙为CC0的第一个时隙和CCn的第一个时隙，第二指示信息为CC0在第一个时隙上的TB数量1，CC1在第一个时隙上的CBG数量2+CC0在第一个时隙上的TB数量1，总和为3，以及CCn在第一个时隙上的TB数量1+CC0在第一个时隙上的TB数量1+CC1在第一时隙上的CBG数量2，总和为4。
在CC1的第二个时隙上，以CC1的第二个时隙为参考时隙，与CC1的第二个时隙的起始时刻相同的至少一个第一时隙为CC0的第一个时隙和CCn的第一个时隙，而CC0的第一个时隙上的TB数量和CCn的第一个时隙上的CBG数量在CC1的第一时隙上已经被统计过，所以，在CC1的第二时隙上对应的第二指示信息为CC1在第二个时隙上的CBG数量2+在第一个时隙上累计的TB和CBG数量4，总和为6。
按照上述计算方法，基站能够获得在CC1上的每个时隙对应的第二指示信息，在此不再赘述。
继续参见图6，在基站获取第一指示信息和第二指示信息的过程中，参考时隙存在与低时延高可靠通信(Ultra-Reliable Low Latency Communicaitons，URLLC)业务对应的CBG或TB时，与URLLC业务对应CBG数量或TB数量单独累计，或与参考时隙的CBG数量或TB数量统一累计。
作为一种示例，以CC1的第四个时隙为例，当URLLC业务来临时，基站无法确定在CC1的第四个时隙上需要调度的CBG数量时，则将与URLLC业务对应的CBG数量单独统计，与URLLC业务的时刻对应的第一指示信息为URLLC业务的CBG数量1+在第四个时隙之前的时隙累计的TB数量和CBG数量9，总和为10；第二指示信息为URLLC业务的CBG数量+在第四个时隙之前的时隙累计的TB数量和CBG数量9，总和为10。
作为另一种示例，仍以CC1的第四个时隙为例，当URLLC业务来临时，基站能够确定在CC1的第四个时隙需要调度的CB数量时，则将与URLLC业务对应的CBG数量与第四时隙的CBG数量统一累计。第一指示信息为URLLC业务的CBG数量1+CC1在第四个时隙上的CBG数量2+在第四个时隙之前的时隙累计的TB数量和CBG数量9，总和为11；第二指示信息为URLLC业务的CBG数量+在第四个时隙之前的时隙累计的TB数量和CBG数量9，总和为10。
第二，参考时隙不是时隙长度最短的时隙。
在参考时隙不是时隙长度最短的时隙的情况下，基站预测所述至少一个第一时隙中时隙长度短于参考时隙的时隙的后续时隙发送的TB和/或CBG的预测数量；基站将所述预测数量累计在所述第一指示信息中。
请参见图7，终端设备被服务分量载波，记为CC0-CC2，CC0-CC2中每个分量载波的时隙长度不相同，以CC2的时隙为参考时隙。以图7所示虚线位置处为例，在虚线位置处需要发送用于指示第一指示信息的指示信息，第一指示信息是参考时隙和至少一个第一时隙上的TB和CBG数量之和，以及在参考时隙之前的时隙累计的TB和CBG数量，以9为例。这时，基站还要预测至少一个第一时隙中时隙长度短于参考时隙的时隙的后续时隙上发送的TB或CBG数量，此处的后续时隙也就是至少一个时隙中时隙长度短于参考时隙的时隙的下一个时隙，可以是最短的，也可以是介于最短和参考时隙之间的，例如图7中所示的CC1在虚线位置上的时隙的下一个时隙，图7中所示的CC1在虚线位置上的下一个时隙上发送的TB或CBG数量以5为例，则需要将预设的预测数量累计在第一指示信息中，总和为14。
在具体实现过程中，当将后续时隙上发送的TB或CBG数量累计在第一指示信息中后，如果后续时隙在真实场景下需要发送的TB或CBG数量小于预测数量，例如实际数量为4，小于预测数量5，基站则在后续时隙中重复发送在后续时隙之前的时隙上已经发送过的TB或CBG；如果后续时隙在真实场景下需要发送的TB或CBG数量大于预测数量，例如实际数量为7，大于预测数量5，则将时隙需要发送的TB或CBG数量在后续时隙的后续资源上隙发送，此处后续资源也就是后续时隙的下一个时隙。
S402：基站向终端设备发送至少用于指示所述第一指示信息的指示信息。
在本申请实施例中，第一指示信息的发送方式可以是隐式、或者是显式发送。例如以第一指示信息是4为例，在以隐式方式发送给终端设备时，指示信息可以是特定值，例如A，在终端设备接收由基站发送的指示信息A时，可以通过指示信息与第一指示信息之间的对应关系，确定出第一指示信息；在以显示方式发送给终端设备时，指示信息可以是第一指示信息本身，也就是4。对于第二指示信息的发送方式可以同第一指示信息的发送方式，在此不再赘述。在下面的介绍中，均以显式发送，参考时隙均以时隙长度最短的时隙为例。
在本申请实施例中，基站向终端设备发送至少用于指示第一指示信息的指示信息的方式包括但不限于以下三种，下面分别介绍。
第一种，基站在聚合窗外的时隙向终端设备发送用于指示所述第一指示信息的指示信息。
请参见图8，终端设备被服务的分量载波，记为CC0-CCn，每个分量载波包括4个时隙，记为时隙0-时隙3(也就是Slot 0-Slot 3)。图8中所示的从Slot 0-Slot 3位置处内的时隙属于一个聚合窗，在该聚合窗内的各个时隙的HARQ反馈信息在同一上行控制信道或同一上行控制信息发送。
在本申请实施例中，聚合窗外的时隙通常指的是分量载波上在聚合窗外，上行时隙之前的时隙。当然基站也可以在聚合窗外的指定时隙上发送用于指示第一指示信息的指示信息。这里的指定时隙，存储在终端设备中，或者由基站配置给终端设备的。基站的配置方式可以是通过无线资源控制(Radio Resource Control，RRC)配置、媒体访问控制单元(Media Access Control Control Element，MACCE)配置，或通过物理下行控制信道配置、或者由RRC层配置参数集合，由媒体访问控制(Media Access Control，MAC)层或物理层从RRC配置的参数集合中配置一个给终端设备。
在本申请实施例中，聚合窗外的指定时隙为第三时隙之前，且与第三时隙间隔k-1个 时隙，第三时隙是终端设备向基站发送上行控制信息UCI的时隙；其中，k由协议规定，或者根据基站配置给终端设备的配置参数获得。
继续参考图8，图8中所示的CCn上以虚线示出的时隙为终端设备向基站发送上行控制信息(Uplink Control Information，UCI)的时隙，也就是第三时隙。那么与第三时隙间隔k-1个时隙是指从第三时隙向前数k个时隙，例如以k＝2，第三时隙是CCn上的第六个时隙为例，指定时隙则是从第六个时隙向前数2个时隙，也就是CCn上的第四个时隙。
在本申请实施例中，k由协议规定，并且存储在终端设备中，或者由基站配置给终端设备的。基站的配置方式可以是通过无线资源控制(Radio Resource Control，RRC)配置、MACCE配置，或通过物理下行控制信道配置、或者由RRC层配置参数集合，由媒体访问控制(Media Access Control，MAC)层或物理层从RRC配置的参数集合中配置一个给终端设备、或者通过K1隐式决定，例如终端设备在slot n获取PDSCH信道对应的数据包，终端设备根据自己的处理能力，在K1时刻反馈对应的HARQ反馈信息，这里说明基站发送最后一个用于指示第一指示信息的DCI信息，需要满足终端设备的处理能力需求。也就是说发送终端设备的聚合窗的第一指示信息的DCI的时域位置为PUCCH所在时域位置n的n-kx位置，kx>＝K1，此处K1的单位可以是时隙，也可以是OFDM符号。
继续参考图8，基站在图8中所示的T2时刻向终端发送第一指示信息，其中，第一指示信息包括的具体内容包括但不限于以下两种，下面分别介绍。
A、第一指示信息为聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量之和。
在A中，第一指示信息为针对整个聚合窗的指示信息，图8中，基站调度分量载波CC0和CC1，在CC0的每个时隙发送一个TB，在CC1的第一个时隙、第二个时隙、第三个时隙、第五个时隙、第六个时隙及第七个时隙中每个时隙发送2个CBG。以CC1的第一个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3；以CC1的第二个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为2；以CC1的第三个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3；以CC1的第五个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3；以CC1的第六个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为2；以CC1的第七个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3，则在聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量之和为3+2+3+3+2+3，总和为16。
B、第一指示信息为聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量，以及聚合窗外的参考时隙和至少一个第一时隙上的TB和CBG数量。
在B中，第一指示信息是针对整个聚合窗、以及聚合窗外的参考时隙和至少一个第一时隙上的TB和CBG数量。继续参考图8，基站调度分量载波CC0和CC1，在CC0的每个时隙发送一个TB，在CC1的第一个时隙、第二个时隙、第三个时隙、第五个时隙、第六个时隙及第七个时隙中每个时隙发送2个CBG。以CC1的第一个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3；以CC1的第二个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为2；以CC1的第三个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第 一时隙上的TB和CBG数量之和为3；以CC1的第五个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3；以CC1的第六个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为2；以CC1的第七个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3，则在聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量之和为3+2+3+3+2+3，总和为16，以及以CC1在聚合窗外的第九个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3，总和为19。
在B中，计算方式适用于在满足上行PUCCH反馈时延的基础，且在聚合窗外的时隙，也就是CC1的第九个时隙上有数据调度的情况，进一步，基站将针对整合聚合窗、聚合窗外的时隙和至少一个第一时隙上的TB和CBG数量的第一指示信息发送给终端设备时，还要将聚合窗外的时隙的第二指示信息发送给终端设备，以保证终端设备能够基于第一指示信息和第二指示信息确定出针对整个聚合窗的第一指示信息。
在第一种实现方式中，在确定基站向终端设备发送的第一指示信息的具体内容后，第一指示信息的发送方式也包括但不限于以下三种，下面分别介绍。
第一种发送方式，基站在聚合窗外的时隙通过DCI向终端设备发送指示信息；其中，DCI具有特定格式或具有特定频域信息，以指示终端设备所述DCI中携带第一指示信息。
在本申请实施例中，指示信息通过携带在DCI中发送，基站可以通过以下两种方式指示终端设备DCI中携带有第一指示信息。
其中，第一种方式DCI具有特定格式，例如Format1/2/3。以Format1为例，在终端设备从基站的信道盲检测出该DCI Format格式为Format1时，就能够确定该DCI中携带了第一指示信息。该方式中，DCI中只发送控制信息，没有数据信息。DCI指示该指示信息为针对一个聚合窗的最后一个第一指示信息，或者最后N个时隙对应的第一指示信息。
第二种方式DCI具有特定频域信息，例如DCI的频域信息对应的起始位置和结束位置相同，则表示这是一个没有调度数据的DCI，DCI中包含第一指示信息相关内容，或者频域信息指示的频域位置小于一个终端设备能够被调度的最小值，或者频域信息的格式为一个特定值，或者频域信息调度了一个终端设备无法使用的频域区域，以指示终端设备该DCI携带了第一指示信息。
第二种发送方式，基站在聚合窗外的时隙通过PDSCH向终端设备发送指示信息，且利用DCI指示终端设备PDSCH中携带有第一指示信息。
在第二种发送方式中，将第一指示信息携带在PDSCH中发送，且利用DCI指示终端设备PDSCH中携带有第一指示信息。
第三种发送方式，基站在聚合窗外的时隙通过DCI向终端设备发送指示信息；其中，指示信息中包括第一指示信息，以及聚合窗的信息。
在本申请实施例中，可以在DCI中显式或者隐式第一指示信息对应的聚合窗信息。例如聚合窗的尺寸、聚合窗的时域信息、或者是聚合窗的频域信息。
第二种，基站在聚合窗内的调度时隙和/或专用时隙向终端设备发送用于指示所述第一指示信息和所述第二指示信息的指示信息。
在本申请实施例中，调度时隙是指需要调度数据的时隙，专用时隙是指专门用于向终端设备发送控制信息，例如DCI信息的时隙。下面分别介绍基站在聚合窗内的调度时隙向终端设备发送用于指示第一指示信息和第二指示信息的指示信息、基站在聚合窗内的专用 时隙向终端设备发送用于指示第一指示信息指示信息、或在聚合窗内调度时隙发送用于指示第一指示信息和第二指示信息的指示信息，在专用时隙向终端设备发送用于指示第一指示信息的指示信息。
1)、基站在聚合窗内的调度时隙向终端设备发送用于指示所述第一指示信息和所述第二指示信息的指示信息。
继续参见图6，基站在CC0-CCn上的每个时隙向终端设备发送用于指示第一信息和第二指示信息的指示信息，例如以显式发送为例，基站在CC0的第一个时隙发送第一指示信息和第二指示信息，也就是(1/4)，基站在CC1的第一个时隙发送第一指示信息和第二指示信息，也就是(3/4)，基站在CCn的第一个时隙发送第一指示信息和第二指示信息，也就是(4/4)，基站在CC1的第二个时隙发送第一指示信息和第二指示信息(6/6)，基站在CC0的第二个时隙发送第一指示信息和第二指示信息(7/9)，CC1在第三个时隙发送第一指示信息和第二指示信息(9/9)，以此类推，直至一个聚合窗结束，以使终端设备能够精确得到HARQ反馈信息的HARQ反馈顺序和反馈比特数。
2)、基站在聚合窗内的专用时隙向终端设备发送用于指示第一指示信息。其中，第一指示信息为聚合窗的起始时隙至专用时隙内的参考时隙和至少一个第一时隙上的TB数量和CBG数量之和。
继续参见图8，专用时隙为CCn上的第二时隙，以CC1上的第一个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3，以CC1的第二个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为2，以CC1的第三个时隙为参考时隙，与参考时隙的起始时刻相同的至少一个第一时隙上的TB和CBG数量之和为3，总和为8，也就是说第一指示信息为8。
3)、在聚合窗内调度时隙向终端设备发送用于指示第一指示信息和第二指示信息的指示信息，在专用时隙向终端设备发送用于指示第一指示信息的指示信息。
在本申请实施例中，请参见图6，在聚合窗的调度时隙，如图6中所示的CC1的每个时隙发送第一指示信息和第二指示信息，同时在专用时隙，如图6所示的虚线位置对应的时刻发送从聚合窗的起始时刻至专用时隙内的参考时隙和至少一个第一时隙上的TB和CBG数量。其中，在CC1的每个时隙发送的第一指示信息和第二指示信息的计算方式同1)，在T2时刻发送的第一指示信息的计算方式同2)，在此不再赘述。
在本申请实施例中，第二种中的第一指示信息和第二指示信息的发送方式可以同第一种方式中的第一种发送方式、第二种发送方式及第三种方式方式，在此不再赘述。
在本申请实施例中，第二种中的第一指示信息的发送方式除了上述三种方式外，还可以通过如下方式发送，具体的：
当在聚合窗内，基站发送的用于指示针对整个聚合窗的第一指示信息的指示信息的次数小于预设值时，基站在聚合窗内，通过多个分量载波重复发送用于指示第一指示信息的指示信息，或通过时隙长度最短的分量载波中的不同时隙重复发送用于指示第一指示信息的指示信息。
通过多个分量载波重复发送的方式。
请参见图9，在聚合窗内的第一竖线时刻处，基站有数据CBG2，3调度给终端设备，此时发送指示信息。若在第二竖线时刻没有TB或CBG需要发送给终端设备时，由于整个聚合窗的第一指示信息只在第一竖线时刻发送了一次，为了提高基站向终端设备发送第一 指示信息的可靠性，基站会在第二竖线时刻发送和第一竖线时刻相同的第一指示信息，当然第一竖线时刻的数据包也可以在第二竖线时刻再发送一次。对于终端设备而言，当发现第二竖线时刻接收到的指示信息与第一竖线时刻相同时，则认为该第一指示信息是针对整个聚合窗的指示信息。
通过时隙长度最短的分量载波中的不同时隙重复发送的方式。
请参见图10，在第二竖线时刻，基站有数据CBG4在CC1上发送给终端设备，同时会发送第一指示信息，由于基站只在CC1上发送一次第一指示信息，如果UE没有正确接收到该第一指示信息，则整个聚合窗的结果会出错，为了提高基站向终端设备发送第一指示信息的可靠性，基站在CC2的第二竖线时刻将第一指示信息。在本申请实施例中，还可以进一步包括第二指示信息，或者第一指示信息和第二指示信息联合发送。此时，在CC2的第二竖线时刻，也可以将CC1的第二竖线时刻的数据包信息携带发送，或者不携带发送。
第三种，基站在聚合窗内的调度时隙和/或专用时隙向终端设备发送用于指示所述第一相关信息和所述第二指示信息的指示信息，以及基站在聚合窗外的时隙向终端设备发送用于指示所述第一指示信息的指示信息。
在本申请实施例中，基站在聚合窗外的时隙向所述终端设备发送用于指示第一指示信息的指示信息的前提条件是基站向终端设备发送的用于指示针对整个聚合窗的第一指示信息的指示信息的数量小于预设值，例如在参考时隙为多个分量载波中时隙长度最短的时隙，且多个分量载波中时隙长度最短的分量载波的数量小于预设值时。
预设值可以是1个，也可以是2个。以预设值是2为例，当多个分量载波中时隙长度最短的分量载波的数量小于2时，也就是在聚合窗内只发送一次整个聚合窗内的用于指示第一指示信息的指示信息的条件下发送，从而能够保证向终端设备发送第一指示信息的可靠性。
基站在CC0-CCn上的每个时隙向终端设备发送用于指示第一信息和第二指示信息的指示信息，例如以显式发送为例，基站在CC0的第一个时隙发送第一指示信息和第二指示信息，也就是(1/4)，基站在CC1的第一个时隙发送第一指示信息和第二指示信息，也就是(3/4)，基站在CCn的第一个时隙发送第一指示信息和第二指示信息，也就是(4/4)，基站在CC1的第二个时隙发送第一指示信息和第二指示信息(6/6)，基站在CC0的第二个时隙发送第一指示信息和第二指示信息(7/9)，CC1在第三个时隙发送第一指示信息和第二指示信息(9/9)，以此类推，直至一个聚合窗结束，然后在聚合窗外的时隙发送第一指示信息，为整个聚合窗的TB和CBG数量，也就是16。
在第三种方式中，网络设备在聚合窗外的指定时隙向终端设备发送用于指示所述第一指示信息的指示信息，此处的指定时隙同第一种中的“指定时隙”，在此不再赘述。
在第三种方式中，在聚合窗内的每个时隙发送第一指示信息和第二指示信息，以及在聚合窗外的时隙发送第一指示信息的发送方式同第一种的三种发送方式，在此不再赘述。
第四种
在本申请实施例中，基站还可以在聚合窗内的专用时隙及聚合窗外的时隙向终端设备发送用于指示第一指示信息的指示信息。基站在聚合窗内的专用时隙发送的第一指示信息为聚合窗的起始时隙至专用时隙内的参考时隙和至少一个第一时隙上的TB数量和CBG数量之和，基站在聚合窗外的时隙发送的第一指示信息为在聚合窗内的参考时隙和至少一个第一时隙上的TB数量和CBG数量之和，例如继续参见图8，基站在聚合窗内的专用时隙 发送用于指示第一指示信息的指示信息为0/8，基站在聚合窗内外的时隙发送用于指示第一指示信息的指示信息时，第一指示信息为8/16。
S403：终端设备根据所述指示信息，向所述基站发送HARQ反馈信息。
在本申请实施例中，HARQ反馈信息为ACK信息、NACK信息、及DXT信息中的任意一种或几种。HARQ反馈信息可以为针对TB级、CBG级或者针对TB和CBG级的反馈信息。其中，针对TB级也就是，一个TB对应一定比特数量的反馈信息；针对CBG级的也就是，当一个TB中包括至少一个CBG级时，每个CBG都对应一定比特数量的反馈信息。
在本申请实施例中，对应基站发送的指示信息内容不同时，终端接收到的指示信息的内容也不相同，下面分别介绍。
一、终端设备接收由基站在所述聚合窗外的时隙发送的用于指示所述第一指示信息的指示信息。
在该情况下，在基站通过不同方式发送指示信息的情况下，终端设备识别第一指示信息的方式也不相同，下面分别介绍。
当基站在聚合窗外的时隙通过DCI发送指示信息时，终端则根据DCI的特定格式或特定频域信息确认DCI中携带第一指示信息；或
当基站在聚合窗外的时隙通过PDSCH发送的指示信息时，终端则利用基站发送的DCI确认所述PDSCH中携带有第一指示信息。
此处的第一指示信息是针对整个聚合窗的指示信息，也就是所述聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量之和。在终端设备获取第一指示信息后，则根据获取的第一指示信息确定HARQ反馈信息。
请参见图8，终端接收到的指示信息以16为例，也就是终端设备通过CC0、CC1、CC2在T2时刻接收由基站发送的16。当终端设备获取16之后，则能够确定在T2时刻需要反馈的HARQ反馈信息的反馈比特为16。若在终端T2时刻接收到由基站发送的16个TB和/或CBG，并且全部接收正确，则在T2时刻反馈的反馈信息为11111111 11111111，若终端设备在T2时刻接收到由基站发送的16TB和/或CBG，但只有15个能够正确接收，这也就就表明在聚合窗内也就是T2时刻内有一个TB或CBG未接收正确，则在T2时刻反馈的反馈信息为0000 0000 0000 0000。
在本申请实施例中，终端设备接收到的第一指示信息中还可以包括第一指示信息对应的聚合窗信息。例如聚合窗的尺寸、聚合窗的时域信息、或者是聚合窗的频域信息。
二、终端设备接收由基站在聚合窗内的专用时隙发送的用于指示第一指示信息的指示信息，以及在聚合窗外的时隙发送的用于指示所述第一指示信息的指示信息。
该第一指示信息为所述聚合窗内的参考时隙和至少一个第一时隙上的TB和CBG数量之和，以及所述聚合窗的起始时隙至专用时隙内的参考时隙和至少一个第一时隙上的TB和CBG数量之和。
请参见图8，终端接收到的指示信息以(0/8)，(8/16)为例，也就是终端设备通过CC0、CC1、CC2在T1时刻接收由基站发送的0/8，以及在T2时刻接收由基站发送的8/16。当终端设备获取(0/8)，(8/16)之后，则能够确定在T1时刻需要反馈的HARQ反馈信息的反馈比特为8，在T1-T2时刻之间需要反馈的HARQ反馈信息的反馈比特也为8，这样，在终端接收到由基站发送TB和CBG后，若在T1时刻接收到8个TB和/或CBG，并且全 部接收正确，则在T1时刻反馈的反馈信息为11111111，在T1-T2时刻之间接收到8个TB和/或CBG，而实际接收正确的TB或CBG数量为7个，这就表明有一个TB或CBG未接收正确，则在T2时刻反馈的反馈信息为00000000。
三、终端设备接收由基站在聚合窗内的调度时隙和/或专用时隙时隙发送的用于指示第一指示信息和第二指示信息的指示信息。
在该方式中，对应基站确定用于指示针对整个聚合窗内的第一指示信息的指示信息只发送一次的情况下，终端设备可能会在多个不同分量载波或时隙长度最短的分量载波的不同时隙重复接收用于指示针对整个聚合窗的第一指示信息的指示信息，在终端设备多次接收指示信息时，则能够确定指示信息中携带的第一指示信息为针对整个聚合窗的指示信息。
继续参见图6，终端接收到的指示信息以(1/4)、(3/4)、(4/4)为例，也就是终端设备通过CC0、CC1、CC2在Slotn时隙接收由基站发送的(1/4)、(3/4)、(4/4)。当终端设备获取(1/4)、(3/4)、(4/4)之后，则能够确定需要反馈的HARQ反馈信息的反馈比特数为4，在CC0的第一个时隙接收到TB，并接收正确的情况下，需要反馈的HARQ反馈比特为1，反馈顺序为第一位，在CC1的第一个时隙接收到两个CBG，并接收正确的情况下，需要反馈的HARQ反馈比特为11，反馈顺序为第二位，在CCn的第一个时隙接收到一个TB，但未接收正确的情况下，需要反馈的HARQ反馈比特为0，反馈顺序为第三位，则终端需要反馈的反馈信息为1110，相应的，在基站接收到由终端反馈的反馈信息后，也能根据第一指示信息确定反馈比特信息中对应的CC及相应的时隙。
第二方面
继续请参见图3，在第一方面中，基站为终端设备分配多个小区。而在第二方面中，假设基站为终端设备分配一个小区，该小区对应一个分量载波，该分量载波包括4个时隙，记为Slot n-Slot n+3，由于NR系统中HARQ定时关系是动态可配置的，所以，在Slot n-Slot n+3的HARQ反馈信息可能在同一PUCCH上反馈，为了使网络设备能够识别终端设备的反馈信息，网络设备和终端设备之间至少要确定终端设备反馈的比特数。
鉴于此，本申请实施例给出以下两种技术方案，下面分别介绍。
第一种技术方案，基站在聚合窗内的调度时隙和/或专用时隙向终端设备发送第一指示信息，以及在聚合窗外的时隙向终端设备发送用于指示第一指示信息的指示信息，其中，在聚合窗内的调度时隙向终端发送的第一指示信息为每个时隙和每个时隙之前的时隙上与数据信道上对应的信息数量和/或与控制信道上对应的信息数量，在聚合窗外的时隙向终端设备发送的第一指示信息为聚合窗内所有时隙上与数据信道对应的信息数量和/或与控制信道对应的信息数量。
第二种技术方案，基站在聚合窗外的时隙向终端设备发送第一指示信息，该第一指示信息包括聚合窗内的所有时隙上与数据信道对应的信息数量和/或与控制信道对应的信息数量之和。
其中，聚合窗的定义同第一方面中的“聚合窗”的定义，与数据信道对应的信息数量、与控制信道对应的信息数量同第一方面中对“与数据信道对应的信息数量及与控制信道对应的信息数量”的介绍，在此不再赘述。
第三方面
现有技术中，当终端设备获知网络设备发送了一个传输块(Transport Block，TB)， 但是终端设备并没有检测到TB的下行控制信息(Downlink Control Information，DCI)，终端设备会反馈基于CBG级的反馈信息。
请参见图11，假设终端设备激活两个分量载波，记为CC0和CC1，每个CC包括4个时隙，记为时隙n-时隙n+3(也就是Slot n-Slot n+3)。通过CC0在Slot n和Slot n+1上发送的TB的HARQ反馈信息及通过CC1在Slot n和Slot n+1上发送的TB的HARQ反馈信息在第一个PUCCH，也就是
Figure PCTCN2018084060-appb-000001
上发送，通过CC0在Slot n+2和Slot n+3上发送的TB的HARQ反馈信息和通过CC1在Slot n+2和Slot n+3上发送的TB的HARQ反馈信息在第二个PUCCH，也就是下表A中所示的
Figure PCTCN2018084060-appb-000002
上发送。其中，每个CC传输一个TB，一个TB中至少包括一个码块组(Coding Block Group，CBG)，例如CC0在Slot n上一个TB包括2个CBG，在Slot n+1上一个TB包括2个CBG，CC1在Slot n上一个TB包括3个CBG，在Slot n+1上一个TB包括2个CBG。
具体的，若假设终端设备规定每个TB反馈的比特信息，以4bits为例，在终端设备接收通过CC0在Slot n收到2个CBG，并正确接收了其中的一个；通过CC0在Slot n+1上收到2个CBG，并接收正确；而未检测到Slot n和Slot n+1上TB的DCI，也就是说在Slotn的DCI丢失的情况下，终端反馈的HARQ反馈信息为ACK、NACK、非连续发送(Discontinuous Transmission，DTX)、DTX、DTX、ACK、ACK、DTX、DTX、DTX，具体请参见下表A。在该技术方案中，终端反馈的HARQ反馈信息是基于CBG级的反馈，会增加信令开销。
表A
Figure PCTCN2018084060-appb-000003
鉴于此，本申请实施例提供一种混合自动重传请求HARQ反馈方法，在与传输块对应的下行控制信息未丢失时，终端设备反馈与CBG对应的反馈信息，在与传输块对应的下行控制信息丢失时，反馈与TB对应的反馈信息，在保证反馈精度的同时减少信令开销，节约系统资源。
下面结合附图介绍本申请实施例提供的技术方案，在下面的介绍过程中，以本申请提供的技术方案应用在图3所示的应用场景中为例，且以网络设备是基站为例。
请参见图12，本申请实施例提供一种反馈HARQ反馈信息的方法，该方法的流程描述如下：
S1201：终端设备接收由基站发送的传输块，传输块中包括至少一个码块组CBG；CBG为所述传输块的发送基本单元；
S1202：终端设备检测与传输块对应的下行控制信息，并根据检测结果向基站发送HARQ反馈信息；
其中，当下行控制信息丢失时，HARQ反馈信息为与传输块对应的非连续发送DTX。
在本申请实施例中，基站发送的传输块的数量可以是一个、可以是两个、也可以是三个。在TB数量为多个时，基站可以通过多个CC在同一时隙发送，也可以通过通过一个CC在不同时隙发送。其中，CC0和CC1的时隙长度可以相同，也可以不相同。
在下面的介绍过程中，CC以CC0和CC1为例，且CC0和CC1的时隙长度相同为例。基站通过CC0和CC1向终端设备发送TB，每个传输块中包括至少一个码块组。继续参考图11，在图11所示的Slot n和Slot n+1中，CC0在Slot n上一个TB包括2个CBG，在Slot n+1上一个TB包括2个CBG，CC1在Slot n上一个TB包括3个CBG，CC1在Slot n+1上一个TB包括3个CBG。
在本申请实施例中，终端设备在接收由基站发送的TB的同时，还接收到由基站发送的与TB对应的DCI信息，DCI中携带有第一指示信息和第二指示信息，终端设备则根据第一指示信息和第二指示信息确定反馈HARQ反馈信息的反馈顺序和反馈比特。此处第一指示信息和第二指示信息的计算同图1所示的计算方法，而当CC0和CC1的时隙长度不相同时，第一指示信息和第二指示信息的计算同第一方面中针对具有不同时隙长度的分量载波的技术方案。
具体的，若CC0在Slot n收到2个CBG，并正确接收了其中的一个，在Slot n+1收到2个CBG，并正确接收，但未检测到CC1在Slot n和Slot n+1上TB的DCI，通过本申请实施例提供的技术方案，在Slot n和Slot n+1的DCI丢失的情况下，终端设备反馈与TB对应的DTX，也就是ACK、NACK、DTX、ACK、ACK、DTX。在本申请实施例中，在终端设备能够检测到与TB对应的DCI并正确接收基站发送的CBG时，反馈的HARQ反馈信息是基于CBG级的，在终端设备未能检测到与TB对应的DCI，也就是DCI丢失时，HARQ反馈信息则是基于TB级的，相对于表格A，本申请实施例提供的表格B更为简单，能够减少HARQ反馈状态，减少需要反馈的比特个数，从而能够在保证反馈精度的同时减少信令开销。
表B
Figure PCTCN2018084060-appb-000004
在本申请实施例中，终端设备反馈的DTX是终端设备和基站约定好的，当基站接收到终端设备反馈的DTX时，则能够确定终端设备未能检测到DCI，需要重新发送该TB中的CBG。
