Description

一种应答信息发送方法及装置
本申请要求在2017年11月17日提交中国专利局、申请号为201711149106.8、发明名称为“一种应答信息发送方法及装置”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，尤其涉及一种应答信息发送方法及装置。
背景技术
目前，在数据传输过程中通常采用混合自动重传请求(hybrid automatic repeat request，HARQ)进程反馈应答信息，以提高数据传输的可靠性。HARQ进程包括下行HARQ进程和上行HARQ进程。其中，在下行HARQ进程中，网络设备向终端发送下行数据，终端根据接收下行数据的情况向网络设备发送HARQ应答信息。HARQ应答信息通常包括正确应答指令(ACKnowledge，ACK)或错误应答指令(Negative ACKnowledge，NACK)。终端若正确接收到网络设备发送的下行数据则向网络设备发送ACK。终端若未正确接收到网络设备发送的下行数据，则向网络设备发送NACK。
随着通信技术的发展，通信系统(例如第五代通信系统5G)中支持可配置的HARQ进程数量，并在单载波单元(component carrier，CC)场景下支持HARQ应答信息码本的动态配置。在单CC场景下，支持HARQ应答信息码本的动态配置可以理解为是终端反馈HARQ应答信息所用的比特数不是固定或者半静态配置的，而是根据网络设备调度的下行数据数量动态变化的。
在单CC的场景下，网络设备调度下行数据过程中，每个时隙上只包含一个用于指示终端在目标时隙上反馈HARQ应答信息的下行调度信令。然而，单个下行调度信令的丢失概率较高，很可能出现终端漏检网络设备发送的下行调度信息，使终端无法正确确定网络设备调度的下行数据的数量，进而使终端确定的HARQ应答信息所用的比特数与网络设备确定的HARQ应答信息所用的比特数不一致，使HARQ应答信息译码失败。
发明内容
本申请实施例提供一种应答信息发送方法及装置，以使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致。
第一方面，提供一种应答信息发送方法，在该方法中，网络设备确定下行调度信令，该下行调度信令可用于确定在同一上行控制信道PUCCH上反馈的应答信息对应的比特数。终端接收网络设备发送的下行调度信令，根据该下行调度信令，确定在同一上行控制信道上反馈的应答信息对应的比特数，若网络设备也根据下行调度信令确定终端在同一上行控制信道上反馈的应答信息对应的比特数，可使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致。
一种可能的设计中，在同一上行控制信道上反馈的应答信息对应的比特数通过第一阈值确定，该第一阈值为网络设备在A(A为正整数)个时间单元内向终端调度的第一下行 数据总数量不超过的阈值。具体的，网络设备确定下行调度信令，该下行调度信令用于网络设备在A个时间单元内分别向终端调度第一下行数据，第一下行数据为应答信息在同一上行控制信道上反馈的下行数据。网络设备确定的下行调度信令用于确定第一阈值，网络设备在A个时间单元内向终端调度的第一下行数据的总数量不超过第一阈值。网络设备向终端发送确定的下行调度信令。终端在A个时间单元内分别接收网络设备发送的下行调度信令，终端根据第一阈值，确定在A个时间单元内接收的第一下行数据对应的应答信息，并在同一上行控制信道上向网络设备发送第一下行数据对应的应答信息。
本申请实施例中，通过第一阈值确定终端发送第一下行数据对应的应答信息的比特数，第一下行数据对应的应答信息的比特数相对固定，故下行调度信令的指示开销较小。
另一种可能的设计中，在同一上行控制信道上反馈的应答信息对应的比特数通过第二阈值确定，该第二阈值为网络设备在A(A为正整数)个时间单元内向终端调度的第一下行数据的码字总数量不超过的阈值。具体的，网络设备确定下行调度信令，该下行调度信令用于网络设备在A个时间单元内分别向终端调度第一下行数据，第一下行数据为应答信息在同一上行控制信道上反馈的下行数据。网络设备确定的下行调度信令用于确定第二阈值，网络设备在A个时间单元内向终端调度的第一下行数据的码字总数量不超过第二阈值。网络设备向终端发送确定的下行调度信令。终端在A个时间单元内分别接收网络设备发送的下行调度信令，终端根据第二阈值，确定在A个时间单元内接收的第一下行数据对应的应答信息，并在同一上行控制信道上向网络设备发送第一下行数据对应的应答信息。
本申请实施例中，通过第二阈值确定终端发送第一下行数据对应的应答信息的比特数，可以准确确定第一下行数据的码字数量，故能更为精确的确定发送第一下行数据对应的应答信息所用的比特数。
又一种可能的设计中，在同一上行控制信道上反馈的应答信息对应的比特数通过第三阈值确定，该第三阈值为网络设备在A(A为正整数)个时间单元内向终端调度的第一下行数据的码块组总数量不超过的阈值。具体的，网络设备确定下行调度信令，该下行调度信令用于网络设备在A个时间单元内分别向终端调度第一下行数据，第一下行数据为应答信息在同一上行控制信道上反馈的下行数据。网络设备确定的下行调度信令用于确定第三阈值，网络设备在A个时间单元内向终端调度的第一下行数据的码块组总数量不超过第三阈值。网络设备向终端发送确定的下行调度信令。终端在A个时间单元内分别接收网络设备发送的下行调度信令，终端根据第三阈值，确定在A个时间单元内接收的第一下行数据对应的应答信息，并在同一上行控制信道上向网络设备发送第一下行数据对应的应答信息。
本申请实施例中，通过第三阈值确定终端发送第一下行数据对应的应答信息的比特数，可以准确确定第一下行数据的码块组数量，故可更为精确的确定发送第一下行数据对应的应答信息所用的比特数。
其中，上述涉及的A个时间单元可以是连续的时间单元，也可以是离散的时间单元。
其中，第一下行数据可以是网络设备通过物理下行控制信道PDCCH调度的物理下行数据信道PDSCH、增强的物理下行控制信道EPDCCH调度的物理下行数据信道PDSCH和半永久性调度SPS调度的物理下行数据信道PDSCH中的至少一种。
又一种可能的设计中，网络设备向终端发送的下行调度信令中可包括指示信息，该指示信息用于指示第一阈值、或用于指示第二阈值或用于指示第三阈值。终端接收包含有指示信息的下行调度信令，可通过指示信息指示的第一阈值，或指示的第二阈值，或指示的 第三阈值，直接确定第一阈值，或确定第二阈值，或确定第三阈值，减少下行调度信令的信令指示开销。
又一种可能的设计中，下行调度信令中包括的指示信息可通过K个比特位指示第一阈值、或指示第二阈值或指示第三阈值。
其中，K为正整数。一种可能的示例中，K可为2或3。

具体实施方式
下面将结合附图，对本申请实施例中的技术方案进行描述。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
1)、网络设备，可以称之为无线接入网(radio access network，RAN)节点(或设备)，是一种将终端接入到无线网络的设备，又可以称为基站。目前，一些RAN节点的举例为：继续演进的节点B(gNB)、传输接收点(transmission reception point，TRP)、演进型节点B(evolved Node B，eNB)、无线网络控制器(radio network controller，RNC)、节点B(Node B，NB)、基站控制器(base station controller，BSC)、基站收发台(base transceiver station,BTS)、家庭基站(例如，home evolved NodeB，或home Node B，HNB)、基带单元(base band unit，BBU)，或无线保真(wireless fidelity，Wifi)接入点(access point，AP)等。另外，在一种网络结构中，RAN节点可以包括集中单元(centralized unit，CU)节点和分布单元(distributed unit，DU)节点。这种结构将长期演进(long term evolution，LTE)系统中eNB的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
2)、终端，又称之为用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)、终端设备(Terminal Equipment)，传输点(transmission and receiver point，TRP或者transmission point，TP)等，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。目前，一些终端的举例为：手机(mobile phone)、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile  internet device，MID)、可穿戴设备，虚拟现实(virtual reality，VR)设备、增强现实(augmented reality，AR)设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等。
3)、下行数据，可以理解为是网络设备向终端发送的数据，可以是物理下行控制信道(physical downlink control channel，PDCCH)调度的物理下行数据信道(physical downlink share channel，PDSCH)、增强的物理下行控制信道(enhanced physical downlink control channel，EPDCCH)调度的PDSCH和半永久性调度(semi-persistent scheduling，SPS)调度的PDSCH中的至少一种。
4)、下行数据对应的应答信息，可以理解为是表征终端是否接收到网络设备发送的数据的一种反馈信息。例如，网络设备在下行传输中采用指定的帧格式向终端发送下行数据，终端需要在上行传输中采用与所述指定帧格式对应的帧格式反馈该下行数据的应答信息。应答信息可以为ACK或NACK。并且采用不同的反馈机制时，应答信息有不同的名称，例如采用HARQ反馈机制时，应答信息可以称为HARQ应答信息。其中，应答信息可以通过物理上行控制信道(physical uplink control channel，PUCCH)信道资源发送。
5)、码字(codeword，CW)码字可以理解为是传输块的组成单位，每一传输块中包括设定数量的码字，比如一个传输块对应一个码字。
6)、码块组(codeword block group，CBG)可以是指数据传输的基本单位，一个传输块中可以包括一个或者多个CBG。一个码字可以包括一个或者多个CBG。
7)、载波单元(component carrier，CC)，可以理解为是网络设备与终端进行数据传输所用载波的组成单位。单CC场景下，在确定的时间单元内，网络设备与终端仅能在一个CC上发生数据交互。
8)、时间单元，可以理解为是在时域上发送和接收数据所采用的时域资源单位，例如可以是时隙、也可以是子帧、还可以是一个或多个OFDM符号。
9)、名词“网络”和“系统”经常交替使用。信息(information)，信号(signal)，消息(message)，信道(channel)有时可以混用。“的(of)”，“相应的(corresponding，relevant)”和“对应的(corresponding)”有时可以混用。应当指出的是，在不强调其区别时，其所要表达的含义是一致的，本领域的技术人员可以理解其含义。
10)、“多个”是指两个或两个以上。“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。字符“/”一般表示前后关联对象是一种“或”的关系。
本申请实施例提供的应答信息发送方法，可应用于图1所示的系统架构。图1中，网络设备与终端可进行数据传输。在数据传输过程中，网络设备向终端发送的数据可称为下行数据，终端向网络设备发送的数据可称为上行数据。为提高数据传输的可靠性，网络设备与终端进行数据传输过程中，可采用诸如HARQ机制等反馈机制，发送应答信息。本发明实施例中主要针对网络设备向终端发送下行数据，终端接收网络设备发送的下行数据，并向网络设备发送下行数据对应的应答信息的过程进行说明。其中，网络设备可向终端发送下行调度信令，通过该下行调度信令向终端调度下行数据，并向终端调度下行数据对应的应答信息。
随着通信技术的发展，通信系统已经演进为第五代(5G)新无线通信系统(New Radio，NR)，本申请实施例以下以应用于5G NR通信系统为例进行说明。应当指出的是，本申请实施例中的方案还可以应用于其他无线通信网络中。
在5G NR通信系统中，终端可处于NR网络的多种架构或配置下，例如单载波、多载波，多小区，有宏eNB/微eNB、远程拉远单元的高密集小区等。终端在单载波场景下，网络设备在每个时间单元上仅通过一个载波单元向终端发送下行调度信令，该下行调度信令用于向终端调度下行数据，并可用于确定应答信息所用的比特数。终端可在对应的时间单元上接收网络设备发送的下行调度信令。然而，单个下行调度信令的丢失概率较高，很可能出现终端漏检网络设备发送的下行调度信令的情况。由于在5G NR通信系统中，终端反馈应答信息所用的比特数是根据网络设备调度的下行数据数量动态变化的，若终端漏检网络设备发送的下行调度信令，使终端无法正确确定网络设备调度的下行数据的数量，进而使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数不一致，使网络设备无法正确译码应答信息。
单载波场景下，网络设备可在不同时间单元上向终端发送下行调度信令，通过该下行调度信令向终端调度下行数据。终端在对应的不同时间单元上接收网络设备发送的下行调度信令，并依据是否接收到下行调度信令所调度的下行数据，向网络设备发送下行数据对应的应答信息。终端针对不同时间单元上接收到的下行数据对应的应答信息可在不同的PUCCH上反馈，也可将多个时间单元上接收到的下行数据对应的应答信息，在同一PUCCH上反馈。为了方便描述，本申请实施例中将应答信息在同一PUCCH上反馈的下行数据，称为第一下行数据，将应答信息在不同PUCCH上反馈的下行数据，称为第二下行数据。
进一步的，本申请实施例中以网络设备在A个时间单元向终端调度的第一下行数据对应的应答信息在同一PUCCH上反馈为例进行说明，其中，A为正整数。A个时间单元可以是连续的时间单元，也可以是离散的时间单元。
针对应答信息在同一PUCCH上反馈的场景，本申请实施例中可在网络设备向终端发送的下行调度信令中增加用于确定在同一PUCCH上反馈的应答信息对应的比特数的下行调度指示(downlink assignment indicator，DAI)，以使终端接收到下行调度信令后，可确定在同一PUCCH上反馈的应答信息对应的比特数，若网络设备也根据下行调度信令确定终端在同一PUCCH上反馈的应答信息对应的比特数，可使终端确定的HARQ应答信息所用的比特数与网络设备确定的HARQ应答信息所用的比特数一致。网络设备使用该确定的应答信息的比特数对应答信息进行译码，可提高译码通过率。
本申请实施例中，可通过网络设备在多个时间单元内向终端调度的下行数据的总数量、或下行数据的码字总数量，或下行数据的码块组总数量，确定同一PUCCH上反馈的应答信息对应的比特数。
有鉴于此，本申请实施例提供了第一种应答信息发送方法，在该第一种应答信息发送方法中，网络设备向终端发送下行调度信令，该下行调度信令用于向终端调度第一下行数据，并用于确定在A(A为正整数)个时间单元内向终端调度的第一下行数据总数量不超过的阈值。本申请实施例中为方便描述，将网络设备在A个时间单元内向终端调度的所述第一下行数据的总数量不超过的阈值称为第一阈值。终端接收网络设备发送的下行调度信令，并根据该下行调度信令中包括的第一阈值，确定第一下行数据对应的应答信息所用的比特数，按照确定的比特数在同一上行控制信道上向网络设备发送第一下行数据对应的应 答信息。网络设备也采用根据第一阈值确定的应答信息所用比特数进行译码，进而可使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致。
本申请实施例还提供了第二种应答信息发送方法，在第二种应答信息发送方法中，网络设备向终端发送下行调度信令，该下行调度信令用于向终端调度第一下行数据，并用于确定在A(A为正整数)个时间单元内向终端调度的第一下行数据的码字总数量不超过的阈值。本申请实施例中为方便描述，将网络设备在A个时间单元内向终端调度的所述第一下行数据的码字总数量不超过的阈值称为第二阈值。终端接收网络设备发送的下行调度信令，并根据该下行调度信令中包括第二阈值，确定第一下行数据对应的应答信息所用的比特数，按照确定的比特数在同一上行控制信道上向网络设备发送第一下行数据对应的应答信息。网络设备也采用根据第二阈值确定的应答信息所用比特数进行译码，进而可使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致。
本申请实施例还提供了第三种应答信息发送方法，在该第三种应答信息发送方法中，网络设备向终端发送下行调度信令，该下行调度信令用于向终端调度第一下行数据，并用于确定在A(A为正整数)个时间单元内向终端调度的第一下行数据的码块组总数量不超过的阈值。本申请实施例中为方便描述，将网络设备在A个时间单元内向终端调度的所述第一下行数据的码块组总数量不超过的阈值称为第三阈值。终端接收网络设备发送的下行调度信令，并根据该下行调度信令中包括的第三阈值，确定第一下行数据对应的应答信息所用的比特数，按照确定的比特数在同一上行控制信道上向网络设备发送第一下行数据对应的应答信息。网络设备也采用根据第三阈值确定的应答信息所用比特数进行译码，进而可使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致。
图2所示为本申请实施例提供的一种应答信息发送方法实施流程图，参阅图2所示，该方法包括：
S101：网络设备确定下行调度信令。
本申请实施例中网络设备确定的下行调度信令用于向终端调度第一下行数据。
本申请实施例中网络设备可确定在一个时间单元上向终端发送的下行调度信令，也可以确定在多个时间单元上向终端发送的下行调度信令。例如，网络设备可确定在时间单元n+k0至时间单元n+k1内的A个时间单元内发送的下行调度信令，所述n、k0、k1为正整数，且k0小于等于k1，A小于等于(k1-k0)。需要说明的是，在时间单元n+k0至时间单元n+k1内的A个时间单元内发送的下行调度信令可以是在时间单元n+k0至时间单元n+k1内各时间单元上连续发送的下行调度信令，也可以是在时间单元n+k0至时间单元n+k1内离散的时间单元上发送的下行调度信令。
本申请实施例中用于向终端调度第一下行数据的下行调度信令还可用于确定终端发送第一下行数据对应的应答信息所用的比特数。
一种可能的实施方式中，用于向终端调度第一下行数据的下行调度信令可用于确定第一阈值。第一阈值可以理解为是网络设备在A个时间单元内向终端调度第一下行数据的总数量不超过的阈值。由于每个第一下行数据对应应答信息的比特数是确定的，故网络设备可通过该第一阈值确定终端发送第一下行数据对应的应答信息的比特数。通常一个第一下行数据对应的应答信息的比特数为1个比特或者2个比特，故此种确定第一阈值的方式，下行调度信令的指示开销较小。
另一种可能的实施方式中，用于向终端调度第一下行数据的下行调度信令可用于确定 第二阈值。第二阈值可以理解为是网络设备在A个时间单元内向终端调度第一下行数据的码字总数量不超过的阈值。由于每个码字对应应答信息的比特数是确定的，故网络设备可通过该第二阈值确定终端发送第一下行数据对应的应答信息的比特数。此种方式相对确定第一阈值的方式，可以准确确定第一下行数据的码字数量，故能更为精确的确定发送第一下行数据对应的应答信息所用的比特数。
又一种可能的实施方式中，用于向终端调度第一下行数据的下行调度信令可用于确定第三阈值。第三阈值可以理解为是网络设备在A个时间单元内向终端调度第一下行数据的码块组总数量不超过的阈值。由于每个码字对应的比特数是确定的，网络设备可通过该第三阈值确定终端发送第一下行数据对应的应答信息的比特数。此种方式相对确定第一阈值的方式，可以准确确定第一下行数据的码块组数量，故可更为精确的确定发送第一下行数据对应的应答信息所用的比特数。
本申请实施例中由于网络设备确定的下行调度信令用于确定第一阈值、或用于确定第二阈值或用于确定第三阈值，由于第一阈值是网络设备在A个时间单元内向终端调度的第一下行数据总数量不超过的阈值、第二阈值是网络设备在A个时间单元内向终端调度的第一下行数据码字总数量不超过的阈值、第三阈值是网络设备在A个时间单元内向终端调度的第一下行数据码块组总数量不超过的阈值，故，根据第一阈值确定的应答信息所用的比特数、或根据第二阈值确定的应答信息所用的比特数，或根据第三阈值确定的应答信息所用的比特数，可以理解为是针对终端在A个时间单元内接收的全部第一下行数据对应的应答信息，以及用于填充到第一阈值或第二阈值或第三阈值的补充比特信息，其中，补充比特信息与否定应答所对应的比特信息相同。
可以理解的是，本申请实施例中，网络设备确定的下行调度信令还可用于指示在所述A个时间单元内发送的下行调度信令调度的第一下行数据对应的应答信息在同一PUCCH上反馈。例如，网络设备确定的下行调度信令可用于指示在时间单元n+k2的同一PUCCH上反馈应答信息。其中，k2为正整数，且大于k1。
进一步的，本申请实施例中网络设备调度的第一下行数据可以是网络设备通过PDCCH、EPDCCH以及SPS中至少一个调度的PDSCH。
S102：网络设备向终端发送下行调度信令，终端接收网络设备发送的下行调度信令。
本申请实施例中网络设备可将确定的下行调度信令，在对应发送下行调度信令的时间单元上向终端发送，例如网络设备可在时间单元n+k0至时间单元n+k1内的A个时间单元上向终端发送下行调度信令。
本申请实施例中终端可在网络设备发送下行调度信令对应的时间单元上接收下行调度信令，例如终端可在时间单元n+k0至时间单元n+k1内的A个时间单元上接收网络设备向终端发送的下行调度信令。
S103：终端根据接收到的下行调度信令，确定下行调度信令调度的第一下行数据对应的应答信息。
本申请实施例中终端若接收到网络设备发送的下行调度信令，该下行调度信令中包括第一阈值，则终端可根据第一阈值确定终端发送第一下行数据对应的应答信息。具体的，终端可根据第一阈值确定应答信息所用的比特数。
本申请实施例中终端若接收到网络设备发送的下行调度信令，该下行调度信令中包括第二阈值，则终端可根据第二阈值确定终端发送第一下行数据对应的应答信息。具体的， 终端可根据第二阈值确定应答信息所用的比特数。
本申请实施例中终端若接收到网络设备发送的下行调度信令，该下行调度信令中包括第三阈值，则终端可根据第三阈值确定终端发送第一下行数据对应的应答信息。具体的，终端可根据第三阈值确定应答信息所用的比特数。
本申请实施例中，终端接收到网络设备发送的下行调度信令后，可按照下行调度信令中包括的第一阈值、或第二阈值，或第三阈值生成第一下行数据对应的应答信息。例如，终端收到的下行调度信令中指示的第一阈值为8，并对应16比特的应答信息，终端在发送应答信息之前，一共收到3个第一下行数据，且每个第一下行数据对应2比特的应答信息，则终端仍需按照16比特发送应答信息。
本申请实施例中，终端生成应答信息后，可按照应答信息的比特数对应的编码方式生成编码后的信息比特，并通过基站配置的PUCCH发送该应答信息。
S104：终端在同一PUCCH上向网络设备发送终端在A个时间单元内接收的第一下行数据对应的应答信息。
本申请实施例中，终端可采用根据第一阈值确定的应答信息所用的比特数，在同一PUCCH(例如时间单元n+k2的同一PUCCH)上向网络设备发送终端在时间单元n+k0至时间单元n+k1内的A个时间单元内接收的第一下行数据对应的应答信息。或者，终端可采用根据第二阈值确定的应答信息所用的比特数，在同一PUCCH(例如时间单元n+k2的同一PUCCH)上向网络设备发送终端在时间单元n+k0至时间单元n+k1内的A个时间单元内接收的第一下行数据对应的应答信息。或者，终端可采用根据第三阈值确定的应答信息所用的比特数，在同一PUCCH(例如时间单元n+k2的同一PUCCH)上向网络设备发送终端在时间单元n+k0至时间单元n+k1内的A个时间单元内接收的第一下行数据对应的应答信息。
本申请实施例中，终端针对在时间单元n+k0至时间单元n+k1内接收的第一下行数据进行应答信息发送的过程示意图，可如图3所示。
本申请实施例中，终端若在时间单元n+k0至时间单元n+k1内的A个时间单元内接收到下行调度信令，则可根据第一阈值、或根据第二阈值、或根据第三阈值，确定第一下行数据对应的应答信息，进而可确定应答信息所用的比特数，并进行应答信息发送。并且网络设备也是根据第一阈值、或根据第二阈值、或根据第三阈值，确定第一下行数据对应的应答信息所用的比特数，故通过本申请实施例提供的方法，可以使终端确定的应答信息所用的比特数与网络设备确定的应答信息所用的比特数一致，提高网络设备译码应答信息的成功率。
进一步的，本申请实施例中，若终端在全部时间单元上都未接收到下行调度信令，则终端不会向网络设备发送正确接收第一下行数据对应的应答信息，此时，网络设备可通过能量检测的方式，确定终端未发送正确接收第一下行数据对应的应答信息。
以下将结合实际应用对本申请实施例涉及的应答信息发送过程，进行详细说明。
一种可能的示例中，本申请实施例中，网络设备向终端发送的下行调度信令中可包括指示信息，该指示信息用于指示第一阈值、或用于指示第二阈值或用于指示第三阈值。终端接收包含有指示信息的下行调度信令，可通过指示信息指示的第一阈值，或指示的第二阈值，或指示的第三阈值，直接确定第一阈值，或确定第二阈值，或确定第三阈值，减少下行调度信令的信令指示开销。
具体的，下行调度信令中包括的指示信息可通过K个比特位指示第一阈值、或指示第二阈值或指示第三阈值。其中，K为正整数。本申请实施例中K的取值不作限定，一种可能的示例中，K可为2或3。
其中，第一阈值、或第二阈值、或第三阈值可能会有多种取值，故本申请实施例中可通过K个比特位的不同取值指示第一阈值的不同取值、或指示第二阈值的不同取值、或指示第三阈值的不同取值。
通常，K个比特位可对应2K种取值，例如K＝2时，可对应00、01、10和11四种二进制取值。本申请实施例中可通过2K种取值中的至少一个取值指示第一阈值的不同取值，且2K种取值中的至少一个取值与指示的第一阈值的取值具有一一对应关系。例如第一阈值的取值包括1、2、4和8四种取值、且K＝2，则可选择00、01、10和11四种二进制取值指示第一阈值的1、2、4和8这四种取值，且每一个二进制取值对应一个第一阈值的取值，例如00指示第一阈值的取值为1、01指示第一阈值的取值为2、10指示第一阈值的取值为4、11指示第一阈值的取值为8。又例如，例如第一阈值的取值包括2、4和8三种取值、且K＝2，则可选择00、01、10和11四种二进制取值中的三个二进制取值指示第一阈值的2、4和8这三种取值，且每一个二进制取值对应一个第一阈值的取值，例如选择00、01和10三个二进制取值指示第一阈值的三个不同取值，00指示第一阈值的取值为2、01指示第一阈值的取值为4、10指示第一阈值的取值为8。当然，具体的二进制取值对应指示哪个第一阈值的取值，本申请实施例不作限定，例如还可以是00指示第一阈值的取值为8、01指示第一阈值的取值为4、10指示第一阈值的取值为2、11指示第一阈值的取值为1。
本申请实施例中，也可通过2K种取值中的至少一个取值指示第二阈值的不同取值，且2K种取值中的至少一个取值与指示的第二阈值的取值具有一一对应关系。或者，本申请实施例中也可通过2K种取值中的至少一个取值指示第三阈值的不同取值，且2K种取值中的至少一个取值与指示的第三阈值的取值具有一一对应关系。
对于通过K个比特位的取值指示第二阈值的取值，或指示第三阈值的取值的具体举例，与上述通过K个比特位的取值指示第一阈值的取值方式类似，本申请实施例在此不再详述。
本申请实施例中，网络设备可向终端发送2K种取值中用于指示第一阈值取值的二进制比特位取值、或用于指示第二阈值取值的二进制比特位取值，或用于指示第三阈值取值的二进制比特位取值，终端接收到用于指示第一阈值取值的二进制比特位取值、或用于指示第二阈值取值的二进制比特位取值，或用于指示第三阈值取值的二进制比特位取值，可确定第一阈值的取值、或确定第二阈值的取值，或确定第三阈值的取值。
本申请实施例中，通过K个比特位指示第一阈值、或指示第二阈值或指示第三阈值，且K个比特位对应2K种取值，2K种取值中的至少一个取值与所述第一阈值具有一一对应关系、或所述2K种取值中的至少一个取值与所述第二阈值具有一一对应关系、或所述2K种取值中的至少一个取值与所述第三阈值具有一一对应关系，使得终端可以根据用于指示第一阈值取值的二进制比特位取值、或用于指示第二阈值取值的二进制比特位取值，或用于指示第三阈值取值的二进制比特位取值，准确确定第一阈值的取值、或第二阈值的取值或第三阈值的取值。
进一步的，由于终端反馈应答信息时，针对一个第一下行数据对应的应答信息(1-2个比特)的PUCCH格式与多个第一下行数据对应的应答信息(多于两个比特)的格式不 同，故，如果终端通过网络设备发送的下行调度信令确定下行调度信令调度的第一下行数据数量为一个，则可采用1-2个比特的PUCCH格式发送应答信息。如果终端通过网络设备发送的下行调度信令确定下行调度信令调度的第一下行数据数量为多个，则可采用多于两个比特的PUCCH格式发送应答信息。本申请实施例中为使终端区分一个第一下行数据或多个第一下行数据进行应答信息发送，第一阈值的取值至少包括1，或第二阈值的取值至少包括M(M为正整数，其中，1个第一下行数据对应M个码字)，或第三阈值的取值至少包括N(N为正整数，其中，1个第一下行数据对应N个码块组)。
示例的，下行调度信令通过指示信息指示第一阈值的取值时，该指示信息指示的第一阈值中至少包括取值为1的第一阈值，或者下行调度信令通过指示信息指示第二阈值的取值时，该指示信息指示的第二阈值中至少包括取值为M的第二阈值，或者下行调度信令通过指示信息指示第三阈值的取值时，该指示信息指示的第三阈值中至少包括取值为N的第三阈值。
示例的，指示信息通过K个比特位指示第一阈值时，K个比特位对应2K种取值中至少有一个取值用于指示取值为1的第一阈值，或者指示信息通过K个比特位指示第二阈值时，K个比特位对应2K种取值中至少有一个取值用于指示取值为M的第二阈值，或者指示信息通过K个比特位指示第三阈值时，K个比特位对应2K种取值中至少有一个取值用于指示取值为N的第三阈值。
更进一步的，本申请实施例中，若终端采用HARQ机制进行应答信息发送，则第一阈值的取值可根据终端的HARQ进程数量确定，或者第二阈值的取值可根据终端的HARQ进程数量确定，或者第三阈值的取值可根据终端的HARQ进程数量确定。
本申请实施例中终端的HARQ进程数量限制了终端能够同时处理的第一下行数据的数量。理论上，如果网络设备按照终端的HARQ进程数量，调度第一下行数据，且所有的第一下行数据对应的应答信息都在同一PUCCH上反馈应答信息，那么终端所需反馈的第一下行数据对应的应答信息的数量也不会超过终端的HARQ进程数量。例如，当终端的HARQ的进程数量为8时，不需要使下行调度信令指示的第一阈值的最大值对应到16。故，本申请实施例中，根据终端的HARQ进程数量确定第一阈值的取值、或第二阈值的取值或第三阈值的取值，能够在终端的HARQ进程数量较小时，提高下行调度信令中指示第一阈值、或第二阈值、或第三阈值的指示信息的指示精度。
示例的，终端的HARQ进程数量为8时，根据终端的HARQ进程数量确定的第一阈值的取值可以为2，4，6，8中的至少一个、或确定的第二阈值的取值可以为2M，4M，6M，8M中的至少一个、或确定的第三阈值的取值为2N，4N，6N，8N中的至少一个。例如，终端的HARQ进程数量为8，下行调度信令通过2个比特位指示第一阈值的取值，则第一阈值的取值可以为2，4，6，8四种取值，或者第一阈值的取值也可以为1，2，4，8四种取值，或者第一阈值的取值也可以为2、4、8三种取值。终端的HARQ进程数量为8，下行调度信令通过2个比特位指示第二阈值的取值，则第二阈值的取值可以为2M，4M，6M，8M四种取值，或者第二阈值的取值也可以为M，2M，4M，8M四种取值，或者第二阈值的取值也可以为2M、4M、8M三种取值。终端的HARQ进程数量为8，下行调度信令通过2个比特位指示第三阈值的取值，则第三阈值的取值可以为2N，4N，6N，8N四种取值，或者第二阈值的取值也可以为N，2N，4N，8N四种取值，或者第二阈值的取值也可以为2N、4N、8N这三种取值。
示例的，终端的HARQ进程数量为16时，根据终端的HARQ进程数量确定的第一阈值的取值可以为4，8，12，16中的至少一个、或确定的第二阈值的取值可以为4M，8M，12M，16M中的至少一个、或确定的第三阈值的取值可以为4N，8N，12N，16N中的至少一个。例如，终端的HARQ进程数量为16，下行调度信令通过2个比特位指示第一阈值的取值，则第一阈值的取值可以为4，8，12，16四种取值，或者第一阈值的取值也可以为1，4，8，16四种取值，或者第一阈值的取值也可以为8、12、16三种取值。终端的HARQ进程数量为16，下行调度信令通过2个比特位指示第二阈值的取值，则第二阈值的取值可以为4M，8M，12M，16M四种取值，或者第二阈值的取值也可以为M，4M，8M，16M四种取值，或者第二阈值的取值也可以为8M、12M、16M三种取值。终端的HARQ进程数量为16，下行调度信令通过2个比特位指示第三阈值的取值，则第三阈值的取值可以为4N，8N，12N，16N四种取值，或者第二阈值的取值也可以为N，4N，8N，16N四种取值，或者第二阈值的取值也可以为8N、12N、16N这三种取值。
示例的，终端的HARQ进程数量为16时，根据终端的HARQ进程数量确定的第一阈值的取值可以为2，4，6，8，10，12，14，16中的至少一个、或确定的第二阈值的取值可以为2M，4M，6M，8M，10M，12M，14M，16M中的至少一个、或确定的第三阈值的取值为2N，4N，6N，8N，10N，12N，14N，16N中的至少一个。例如，终端的HARQ进程数量为16，下行调度信令通过3个比特位指示第一阈值的取值，则第一阈值的取值可以为2，4，6，8，10，12，14，16八种取值，或者第一阈值的取值也可以为1，2，4，8，10，12，14，16四种取值，或者第一阈值的取值也可以为2，4，6，8四种取值。终端的HARQ进程数量为16，下行调度信令通过3个比特位指示第二阈值的取值，则第二阈值的取值可以为2M，4M，6M，8M，10M，12M，14M，16M八种取值，或者第二阈值的取值也可以为M，2M，4M，8M，10M，12M，14M，16M八种取值，或者第二阈值的取值也可以为2M，4M，6M，8M三种取值。终端的HARQ进程数量为16，下行调度信令通过3个比特位指示第三阈值的取值，则第三阈值的取值可以为2N，4N，6N，8N，10N，12N，14N，16N八种取值，或者第二阈值的取值也可以为N，2N，4N，8N，10N，12N，14N，16N八种取值，或者第二阈值的取值也可以为2N，4N，6N，8N这四种取值。
本申请又一种可能的实施例中，第一阈值的取值由网络设备通过高层信令配置、或第二阈值的取值由网络设备通过高层信令配置或第三阈值的取值由网络设备通过高层信令配置。本申请实施例中第一阈值的不同取值、或第二阈值的不同取值、或第三阈值的不同阈值由网络设备通过高层信令配置，可进一步增加指示第一阈值、或第二阈值、或第三阈值的指示灵活性。并且能够在具有相同下行调度信令的指示开销情况下，提高指示精度。
进一步的，针对上述各实施例中，网络设备在A个时间单元内向所述终端调度所述第一下行数据的各下行调度信令确定的第一阈值相同。示例的，本申请实施例中若第一阈值的取值有多种，下行调度信令通过指示信息指示第一阈值的取值时，网络设备在A个时间单元内向所述终端发送的各下行调度信令中包括的指示信息所指示的第一阈值的取值为同一取值。或网络设备在A个时间单元内向所述终端调度所述第一下行数据的各下行调度信令确定的第二阈值相同。示例的，本申请实施例中若第二阈值的取值有多种，下行调度信令通过指示信息指示第二阈值的取值时，网络设备在A个时间单元内向所述终端发送的各下行调度信令中包括的指示信息所指示的第二阈值的取值为同一取值。或网络设备在A个时间单元内向所述终端调度所述第一下行数据的各下行调度信令确定的第三阈值相同。 示例的，本申请实施例中若第三阈值的取值有多种，下行调度信令通过指示信息指示第三阈值的取值时，网络设备在A个时间单元内向所述终端发送的各下行调度信令中包括的指示信息所指示的第三阈值的取值为同一取值。
上述主要从网络设备和终端交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是，网络设备和终端为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本申请中所公开的实施例描述的各示例的单元(器、器件)及算法步骤，本申请实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本申请实施例的技术方案的范围。
本申请实施例可以根据上述方法示例对网络设备和终端进行功能单元(器、器件)的划分，例如，可以对应各个功能划分各个功能单元(器、器件)，也可以将两个或两个以上的功能集成在一个处理单元(器、器件)中。上述集成的单元(器、器件)既可以采用硬件的形式实现，也可以采用软件功能单元(器、器件)的形式实现。需要说明的是，本申请实施例中对单元(器、器件)的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
