本申请要求于2019年01月11日提交中国专利局、申请号为201910038796.2、申请名称为“一种信息处理方法、终端设备及网络设备”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
本申请涉及无线通信领域，尤其涉及一种信息处理方法、终端设备及网络设备。
背景技术
第五代移动通信技术(5th generation，5G)的通信系统相比于前几代移动通信系统在传输速率、时延及功耗等方面都提出了更高的要求。国际电信联盟(international telecommunication union，ITU)将增强型移动宽带(enhanced mobile broadband，eMBB)、海量机器类型通信(massive machine-type communications，mMTC)和超可靠低延迟通信ultra reliable and low latency communications，URLLC)定义为未来5G的三大典型业务，这为5G标准的制定指明了方向。
URLLC业务作为5G的三大典型业务之一，主要应用于无人驾驶、远程医疗等应用场景，对可靠性、时延以及信令开销等性能指标提出了更加严格的要求。例如，数据传输可靠性达到99.999％，传输时延低于1ms，或者在满足高可靠性及低时延要求下，尽可能减小指令开销。在处理URLLC业务时，终端设备接收到网络设备发送的物理下行共享信道(physical downlink shared channel，PDSCH)中承载的下行数据之后，会根据下行数据的译码结果向网络设备发送反馈信息。但是，在此过程中会出现重复反馈的情况，增加了上行资源的开销，并且降低了数据传输的可靠性。
发明内容
本申请实施例提供一种信息处理方法、终端设备及网络设备，可以提高传输的可靠性，以及减少上行资源的开销。
第一方面，本申请实施例提供了一种信息处理方法，包括：终端设备接收网络设备发送的下行控制信息DCI，DCI用于调度物理下行共享信道PDSCH；然后在第一时隙向网络设备发送N个码本，其中，N个码本包括一个第一码本和N-1个第二码本，第一码本中PDSCH对应的反馈比特位上为PDSCH的反馈信息，第二码本中的PDSCH对应的反馈比特位上为填充信息，N为大于等于2的整数。通过将PDSCH的反馈信息在N个码本中的一个码本中进行反馈，在剩余N-1个码本中PDSCH对应的反馈比特位填充否定应答NACK。这样，网络设备可以获知包括真实的反馈信息的码本，并且可以确定包括填充信息的码本，从而可以避免网络设备和终端设备确定的反馈信息不一致，保证传输的可靠性。并且，由于填充信息是已知信息，可以用于剩余N-1个码本的CRC校验，从而进一步提高填充信息所在的码本中反馈信息传输的可靠性。
在一种可能的设计中，在回退模式(fallback)下，即DCI的预设格式为format1_0， 或者DCI的预设格式为用于在随机接入过程中进行数据调度的DCI格式时，当DCI中包含DAI的指示域取值为1、且该DCI由终端设备所在主小区(on the pcell)接收到时，第一码本中仅包括该DCI调度的PDSCH的反馈信息，而不包括其他PDSCH的反馈信息以及其他任何填充信息。通过减少反馈的码本的比特数，从而减少上行资源的开销。
在另一种可能的设计中，终端设备在接收网络设备发送的下行控制信息DCI之前，可以接收网络设备发送的第一指示信息，第一指示信息用于指示码本模式。使得终端设备可以在不同的码本模式下根据不同的码本生成方式生成码本。由于不同的码本生成方式，生成的码本大小不同，从而能够实现上行反馈信息不同的可靠性需求，以及实现不同的上行资源利用率。
在另一种可能的设计中，终端设备可以接收网络设备通过高层信令发送的第一指示信息。在另一种可能的设计中，所述码本模式为半静态码本模式。
在另一种可能的设计中，PDSCH的反馈信息为根据PDSCH的译码结果确定的，当PDSCH的译码结果为正确时，PDSCH的反馈信息为肯定应答ACK，当PDSCH的译码结果为错误时，PDSCH的反馈信息为否定应答NACK。
在另一种可能的设计中，第一时隙可以由DCI指示，DCI中可以包括第二指示信息，该第二指示信息用于指示第一时隙。从而使得终端设备确定生成码本所在的时隙。终端设备可以根据第二指示信息动态的确定上行反馈时隙，从而满足不同的终端设备的处理能力需求，以及实现不同的时延需求。
在另一种可能的设计中，DCI包括第三指示信息，第三指示信息用于指示N个码本中的第一码本。从而使得终端设备确定所述PDSCH的反馈信息所在的码本。终端设备可以根据第三指示信息动态地确定实际发送的反馈信息所在的码本，且终端设备和网络设备有一致的理解，保证了反馈信息传输有效性。
在另一种可能的设计中，PDSCH对应的反馈比特位为根据所述PDSCH占用的时域资源确定的。

在另一种可能的设计中，终端设备在接收网络设备发送的下行控制信息DCI之前，可以接收网络设备发送的第一指示信息，第一指示信息用于指示码本模式。使得终端设备可以在不同的码本模式下根据不同的码本生成方式生成码本。由于不同的码本生成方式，生成的码本大小不同，从而能够实现上行反馈信息不同的可靠性需求，以及实现不同的上 行资源利用率。
在另一种可能的设计中，终端设备可以接收网络设备通过高层信令发送的第一指示信息。

采用这种方案，通过在N个码本中的一个码本中反馈释放半静态调度PDSCH的反馈信息，在剩余N-1个码本中释放半静态调度PDSCH对应的反馈比特位上填充NACK信息。这样，网络设备可以获知真实的反馈信息的码本，以及非真实的反馈信息的码本，从而可以避免网络设备和终端设备确定的反馈信息不一致，保证传输的可靠性。并且，由于填充信息是已知信息，可以用于剩余N-1个码本的CRC校验，从而进一步提高传输的可靠性。
在一种可能的设计中，在回退模式(falback)下，即DCI的预设格式为format1_0，或者DCI的预设格式为用于在随机接入过程中进行数据调度的DCI格式时，当DCI中包含DAI的指示域为1、且该DCI由终端设备所在主小区(on the pcell)接收到时，第一码本中仅包括该DCI指示的释放半静态调度PDSCH的反馈信息，而不包括其他释放半静态调度PDSCH的反馈信息以及其他任何填充信息。通过减少反馈的码本的比特数，从而减少上行资源的开销。

具体实施方式
下面结合本申请实施例中的附图对本申请实施例进行描述。
第三代合作伙伴项目(3rd Generation Partnership Project，3GPP)的无线接入网(radio access network，RAN)和RAN 1工作组对URLLC业务的性能指标的做了如下定义。
时延：用户应用层数据包从发送端的无线协议栈层2/3的服务数据单元(service data unit，SDU)到达接收端的无线协议栈层2/3SDU所需的传输时间。URLLC业务对于上行和下行的用户面时延要求均为0.5ms，但是仅适用于发送端和接收端都不处于非连续接收态(discontinuous reception，DRX)。该时延为平均时延，不与下面的可靠性要求绑定。
可靠性：发送端在一定时间内向接收端传输X比特数据的成功概率，该时间仍然定义为用户应用层数据包从发送端的无线协议栈层2/3SDU到达接收端的无线协议栈层2/3SDU所需的时间。对于URLLC业务，一般要求在1ms内发送32bytes数据达到99.999％的可靠性。但是，在实际应用场景下，URLLC业务不同，可靠性需求也不同，例如某些极端苛刻的工业控制需要在时延0.25ms内达到99.9999999％的可靠性。
系统容量：在满足一定比例的中断用户前提下的系统所能达到的小区最大吞吐量，其中，中断用户可以为无法满足在一定时延范围内的可靠性需求的用户。
码本：本申请中码本是指混合自动重传请求(hybrid automatic repeat request，HARQ)码本，具体是指将所有下行数据信道PDSCH的反馈信息比特串联形成的信息比特。
时隙(slot)：数据调度的一种时域单位，在正常循环前缀下，一个slot有14个符号，在扩展循环前缀下，一个slot有12个符号。
在本申请实施例中的符号也可以称为时域符号，这里的时域符号可以是正交频分复用(orthogonal frequency division multiplexing，OFDM)符号，也可以是离散傅里叶变换扩展正交频分复用(discrete fourier transform spread OFDM，DFTS-OFDM)符号。
下行控制信息(downlink control information，DCI)：主要用于调度下行数据信道PDSCH。其中调度PDSCH是指，在DCI中包含PDSCH接收需要的信息，例如：时域信息、频域信息和调制编码方式信息等等。
时域区间：是指将一时隙的14个符号，或者12个符号划分为多个区间，每一个区间为一个时域区间。例如一个时隙的14个符号划分为2个时域区间，其中该时隙的前7个符号为第一个时域区间，该时隙的后7个符号为二个时域区间。再例如，一个时隙的14个符号可以划分为3个时域区间，其中第1～4个符号为第一个时域区间，第5～8个符号为第二个时域区间，第9～12个符号为第三个时域区间，第13～14个符号为第四个时域区间。
如图1所示，图1是本申请实施例提供的一种通信系统100的架构示意图。该通信系统100可以包括网络设备110和终端设备101～终端设备106。应理解，可以应用本申请实施例的方法的通信系统100中可以包括更多或更少的网络设备或终端设备。网络设备或终端设备可以是硬件，也可以是从功能上划分的软件或者以上二者的结合。网络设备与终端设备之间可以通过其他设备或网元通信。在该通信系统100中，网络设备110可以向终端设备101～终端设备106发送下行数据。当然，终端设备101～终端设备106也可以向网络 设备110发送上行数据。终端设备101～终端设备106可以是蜂窝电话、智能电话、便携式电脑、手持通信设备、手持计算设备、卫星无线电装置、全球定位系统、掌上电脑(personal digital assistant，PDA)和/或用于在无线通信系统100上通信的任意其它适合设备等等。通信系统100可以采用公共陆地移动网络(public land mobile network，PLMN)、设备到设备(device-to-device，D2D)网络、机器到机器(machine to machine，M2M)网络、物联网(internet of things，IoT)或者其他网络。此外，终端设备104～终端设备106也可以组成一个通信系统。在该通信系统中，终端设备105可以发送下行数据给终端设备104或终端设备106。在本申请实施例中的方法可以应用于图1所示的通信系统100中。
基于上述通信系统100，终端设备接收到网络设备发送的PDSCH中承载的下行数据后，会根据下行数据的译码结果，向网络设备发送反馈信息。其中，反馈信息的生成主要包括如下步骤：
1001、确定反馈时间单元。
反馈信息可以为HARQ响应消息，即：数据接收的肯定应答(acknowledge，ACK)或者数据接收的否定应答(nacknowledge，NACK)。从终端设备接收到下行数据到终端设备向网络设备反馈ACK/NACK之间满足n+k1的定时关系。其中，n代表接收下行数据PDSCH的时间单元，K1代表PDSCH接收的时间单元到对应的ACK/NACK反馈的时间单元之间相差的时间单元，并通过DCI指示K1。其中，时间单元可以为时隙(slot)。例如，如图2所示，图2是一种时间单元的示意图。终端设备在第n个slot接收下行数据，若K1＝4，则在第n+4个slot向网络设备反馈ACK/NACK。也就是确定的反馈时间单元为第n+4个slot。
1002、在反馈时间单元生成HARQ_ACK码本。
如果确定要在第n+4个slot发送反馈信息，假设第n+4个slot为第i个slot,我们记为slot i，则终端设备在slot i根据所有需要反馈的ACK和NACK，生成一个HARQ_ACK码本。不同的码本模式下，在一个时隙生成一个HARQ_ACK码本的生成方式不同，具体各种码本模式下码本的生成方式包括：
(1)半静态码本模式
对于半静态码本模式(又称Type 1HARQ Codebook)下的HARQ_ACK码本生成方式，终端设备首先确定一个K1集合，K1集合包含多个K1的值。然后根据K1集合，从slot i往前推，确定所有可能在slot i发送反馈信息的下行数据PDSCH所在的slot。例如确定K1集合为{0，1，2，3，4}。如图3所示，从第i个slot开始，按照K1集合，可以确定在第(i-4)、(i-3)、(i-2)、(i-1)和(i)个slot的PDSCH都有可能在slot i反馈ACK/NACK。如果第(i-4)、(i-3)、(i-2)、(i-1)和(i)个slot中接收到一个DCI，该DCI指示K1，根据该K1确定该DCI调度的数据要在slot i反馈，则在sloti需要反馈所有第(i-4)、(i-3)、(i-2)、(i-1)和(i)slot中所有PDSCH候选时机(candidate occasion)的反馈信息，如果这些slot中有些PDSCH候选时机没有接收到PDSCH，则该PDSCH候选时机对应的反馈比特位就填充NACK，如果在某个PDSCH候选时机接收到了PDSCH，则该PDSCH时机对应的反馈比特位上面反馈该接收到的PDSCH的反馈信息。其中，PDSCH候选时机的确定方式，以及码本的生成方式如下。
在确定的第(i-4)、(i-3)、(i-2)、(i-1)和(i)个slot中，每个slot按照下面的方式确定PDSCH候选时机(candidate occasion)，具体包括：终端设备首先接收网络设备通过高层信令发送的配置信息，该配置信息为一个时域资源表格，该表格最多包含16行，每一行指示一个PDSCH可能占用的时域资源的开始符号S和一个符号个数L，S表示该时域资源在一个slot中开始时域符号的位置，L表示从开始符号S开始、该时域资源在一个slot所占的时域符号的个数。然后对时域重叠的时域资源进行切分，确定PDSCH候选时机，从而确定一个slot反馈的比特数。具体可以根据这些时域资源中结束符号最靠前的时域资源的结束位置进行切分，将一个slot内所有的时域资源关联到一个或多个PDSCH候选时机，从而确定PDSCH的候选时机。
例如，如图3所示，图3是一种半静态码本模式下的PDSCH candidate occasion确定的示意图。如果终端设备接收网络设备通过高层信令发送的配置信息，该配置信息为一个时域资源表格，该表格包含16行，每一行指示一个PDSCH可能占用的时域资源，16个时域资源分别对应图3中的时域资源#0～时域资源#15，对该16个时域资源进行切分，切分位置如图3中虚线所示。第一个切分位置为时域上结束符号最靠前时域资源的结束位置，即时域资源#12的结束位置，确定被该切分位置切到的资源，即为时域资源#0,#1,#2,#3,#4,#6，所述时域资源{#0,#1,#2,#3,#4,#6,#12}对应一个PDSCH候选时机；之后从剩余的时域资源，即时域资源{#5,#7,#8,#9,#10,#11,#13,#14,#15}中确定第二个切分位置为这些时域资源中结束符号最靠前的时域资源的结束位置，即时域资源#13和时域资源#9的结束位置，然后按照这个切分位置切分后，得到第二个PDSCH候选时机，该第二个PDSCH候选时机对应时域资源{#7,#9,#13}；按照前面所述的方法可以得到4个PDSCH candidate occasion，对应图3中小括号内的数字，分别包含时域资源{#0,#1,#2,#3,#4,#6,#12}、{#7,#9,#13}、{#5,#8,#10,#14}、{#11,#15}。
在确定每个slot中的PDSCH候选时机之后，可以确定每个slot的反馈信息的总的比特数，每个slot的反馈信息的总的比特数为该slot中每个PDSCH候选时机对应的反馈比特数之和。每个PDSCH候选时机对应的反馈比特位可以为H比特，具体对应H可以为高层信令配置的数值，或者H为1，本文对此不做限定，后续以反馈比特位H＝1个来说明。具体来说，确定的PDSCH候选时机按照时域位置从前到后的顺序分别对应H个反馈比特位。每个PDSCH candidate occasion关联一个或多个时域重叠的时域资源，这些时域重叠的时域资源上最多只允许传输1个PDSCH，该PDSCH对应H比特的反馈信息，且该PDSCH对应的反馈比特位为该PDSCH所在的PDSCH候选时机对应的反馈比特位。
例如，如图3所述的4个PDSCH候选时机，假设H＝1，也就是PDSCH候选时机对应的反馈比特数为1比特，则每个slot中的反馈信息的总的比特数为4比特。PDSCH候选时机(1)，也就是时域资源{#0,#1,#2,#3,#4,#6,#12}对应的候选时机，在时域上最靠前，则该PDSCH候选时机对应的反馈比特位在该slot的反馈信息的第一位。也就是PDSCH候选时机(1)～(4)分别对应该slot的反馈信息中的第1～4个比特位。如果H＝2，则PDSCH候选时机(2)对应前2个比特。不再赘述。在PDSCH候选时机(1)关联的时域资源{#0,#1,#2,#3,#4,#6,#12}中，假设在时域资源#2上收到了PDSCH，则在该slot的反馈信息中第2个比特位上为该PDSCH的反馈信息。
将上行slot i关联的多个下行slot，例如前述的第(i-4)、(i-3)、(i-2)、(i-1)和(i)个slot中所有slot内的反馈信息按照时域位置从前往后进行串联，每个PDSCH candidate occasion对应自己的反馈信息，形成最终的HARQ-ACK码本。
(2)动态码本模式
对于动态码本模式(又称Type 2HARQ Codebook)下的HARQ_ACK码本生成方式，如果终端设备接收到物理下行控制信息DCI，该DCI指示K1，根据该K1确定该DCI调度的PDSCH要在slot i反馈，则该slot i的HARQ_ACK码本中包含该PDCCH调度的数据的反馈信息，或者包含该PDCCH指示的半静态调度(semi-persistent scheduling，SPS)的PDSCH释放的反馈信息。
1003、确定物理上行控制信道(physical uplink control channel，PUCCH)资源。
当HARQ-ACK码本确定后，终端设备首先确定需要反馈码本的比特数目，即负载大小(payload size)，然后根据payload size选择一个PUCCH资源集合(resource set)。每个PUCCH resource set中包含最少8个、最多32个PUCCH resource。进一步地，终端设备可以根据接收到的、调度ACK/NACK属于该码本的最后1个PDCCH中ACK/NACK资源指示(ACK/NACK resource indicator，ARI)字节和隐式指示，确定反馈该ACK/NACK码本的PUCCH资源是选定set中的哪一个资源。在该PUCCH资源上发送所述码本。
其中，PUCCH resource sets是网设备通过高层信令配置的。
从上述过程可以看出，以slot为单位生成HARQ_ACK码本，无论是采用半静态码本模式生成还是动态码本模式生成。在一个slot中只能生成一个HARQ_ACK码本，也就是只能反馈一次。例如，如图4所示，终端设备在第1个slot接收到eMBB业务的PDSCH、且调度该PDSCH的DCI指示K1＝2，则该PDSCH对应的反馈信息应在第3个slot反馈。在第2个slot接收到URLLC业务的PDSCH、且调度该PDSCH的DCI指示指示K1＝1,则该PDSCH对应的反馈信息在第3个slot反馈。两个PDSCH的反馈信息都要在第3个slot中反馈，根据前面所述的半静态码本模式和动态码本模式的描述，终端设备在第3个slot中针对eMBB业务和针对URLLC业务的反馈信息统一生成一个HARQ_ACK码本，然后按照第二个DCI，即调度URLLC业务的DCI指示来确定最终的PUCCH资源，进行反馈。
由于URLLC业务对时延要求比较高，而且可靠性要求也比较高，因此用于URLLC业务对应的PDSCH的反馈信息发送的PUCCH资源较多，以便通过降低码率来保证PUCCH的可靠性。由于URLLC业务的反馈信息与eMBB业务的反馈信息只能生成一个码本，为了保证URLLC业务的可靠性，需要分配更大的PUCCH资源，相当于eMBB业务也需要同样低的码率来传输，这样会造成资源的浪费。但是如果保障不浪费资源，则无法保障URLLC业务的反馈信息的可靠性。为了解决该技术问题，可以采用一个slot内生成多个HARQ_ACK码本，从而实现不同业务的不同的可靠性需求。
例如，在动态码本模式时，在一个slot内生成多个HARQ码本方式可以包括如下几种：
第一种方式：通过将上行的时隙划分为多个时域区间，在每个时域区间内生成一个HARQ_ACK码本，如果某个PDSCH对应的PUCCH资源在某一个时域区间中(PUCCH的开始符号或者结束符号在某一个时域区间中)，则该数据对应的反馈信息就包含在该时 域区间的HARQ_ACK码本中反馈。具体来说，终端设备接收到物理下行控制信息DCI，该DCI指示K1，根据该K1确定该DCI调度的PDSCH要在slot i反馈，并且按照前述的1003步骤确定该PDSCH对应的PUCCH资源，然后根据该PUCCH资源的所在的时域区间确定该PDSCH反馈信息对应的码本。
例如，如图5所示，一个大格表示一个slot，一个上行的slot被分为2个时域区间。在slot i-2中收到第一个PDSCH1，调度该PDSCH1的DCI 1指示K1＝2，也就是在2个slot后，即slot i反馈ACK/NACK，并且DCI1还指示了对应的PUCCH1资源。在slot i-1中收到第二个PDSCH2，调度该PDSCH2的DCI2指示K1＝1，也就是在1个slot后，也是slot i反馈ACK/NACK，并且DCI2还指示了对应的PUCCH2资源。由于PUCCH1的结束符号在slot i的第二个时域区间内，PUCCH2的结束符号在第一个时域区间内，则PDSCH1的反馈信息在slot i的第二个HARQ_ACK码本中反馈，PDSCH2对应的反馈信息在slot i的第一个HARQ_ACK码本中反馈。
第二种方式，通过将PDSCH进行分组，每一组生成一个HARQ_ACK码本。例如，图5中，在slot i-2中收到第一个PDSCH1，调度该PDSCH1的DCI 1指示K1＝2，也就是在2个slot后，即slot i反馈ACK/NACK，在slot i-1中收到第二个PDSCH2，调度该PDSCH2的DCI2指示K1＝1，也就是在1个slot后，也是slot i反馈ACK/NACK。如果PDSCH1与PDSCH2属于同一组，则将二者的反馈信息包含在一个HARQ_ACK码本中，如果属于不同组，则将二者的反馈信息包含在不同的HARQ_ACK码本中。
具体分组的方式可以依据下面的任意一种：调度PDSCH的DCI格式、调度PDSCH的DCI的加扰方式RNTI、PDSCH的长度或PDSCH的映射类型等等，本申请不做限定。
例如，调度PDSCH的DCI格式可以分为N组，每一组生成一个码本。假设调度PDSCH的DCI格式为DCI格式1的生成一个码本，调度PDSCH的DCI格式为DCI格式2的生成一个码本，……，调度PDSCH的DCI格式为DCI格式N的生成一个码本，也就是说N个DCI格式生成N个码本。又或，N组DCI中每组中的DCI格式的个数不唯一。如果调度PDSCH1的DCI1属于N组DCI中的第f组，则该PDSCH的反馈信息就包含在第f组DCI对应的码本中。
再例如：调度PDSCH的DCI加扰RNTI可以分为N组，每一组生成一个码本。假设调度PDSCH的DCI加扰RNTI为RNTI1的生成一个码本，调度PDSCH的DCI加扰RNTI为RNTI2的生成一个码本，……，调度PDSCH的DCI加扰RNTI为RNTIN的生成一个码本,也就是说N个DCI加扰RNTI生成N个码本。又或，N组DCI中每组中的DCI加扰RNTI不唯一。如果调度PDSCH1的DCI1的加扰RNTI1属于N组DCI中的第f组，则该PDSCH的反馈信息就包含在第f组DCI的加扰RNTI对应的码本中。
对于半静态码本模式，在一个slot内生成多个HARQ码本方式可以包括如下几种：
第一种方式，通过将上行的时隙划分为多个时域区间，在每个时域区间对应一个HARQ_ACK码本，因此在一个时隙生成多个HARQ_ACK码本。终端设备先确定反馈的时间单元，例如，采用前述的步骤1001的方式确定反馈的时间单元，确定上行时隙为slot i。然后该slot i中的多个码本中每个码本的生成方式都可以参照前述反馈信息的生成步骤1002中描述的生成HARQ_ACK码本的方式生成。由于所述多个HARQ_ACK码本在一 个时隙中，按照前面所述的生成码本的方式，在一个时隙中会生成多个完全相同的HARQ_ACK码本。
第二种方式，通过将在一个上行时隙发送反馈信息的PDSCH进行分组，每一组生成一个HARQ_ACK码本。先确定反馈的时间单元，采用前述步骤1001确定反馈时间单元，确定上行时隙为slot i。slot i中的多个码本中每个码本的生成方式都可以参照前述步骤1002的方式生成。由于所述多个HARQ_ACK码本在一个时隙中，按照前面所述的生成码本的方式，在一个时隙中会生成多个完全相同的HARQ_ACK码本。
例如，在一个上行时隙生成2个HARQ码本，可以从slot i开始向前推，根据K1集合，假设K1集合为{0，1，2，3}，确定可能在slot i发送反馈信息的数据所在的slot。如图6所示，确定出4个slot，即slot i-3、slot i-2、slot i-1和slot i都在slot i发送反馈信息。根据前面半静态码本模式生成码本方式的描述，在这2个HARQ_ACK码本中，都需要包含这4个slot中的反馈信息。如果PDSCH1和PDSCH2对应的译码结果为正确，需要在2个HARQ_ACK码本中都反馈ACK，这样会出现重复反馈的问题，导致上行资源的浪费。如果重复反馈结果相同的，例如一个ACK被重复反馈了2次，如果其中一个传输过程中出现错误，网络设备接收到的反馈信息一个是ACK，而另一个是NACK，则无法判断到底哪个正确，造成与终端设备确定的反馈信息不一致，降低数据传输的可靠性。
另外，对于半静态码本模式，只要收到一个DCI，根据该DCI确定可在slot i发送该DCI调度的PDSCH的反馈信息所在的slot，如slot i。可以从slot i开始向前推，根据K1集合，假设K1集合为{0，1，2，3}，确定可能在slot i发送反馈信息的数据所在的slot。如图6所示，确定出4个slot，即slot i-3、slot i-2、slot i-1和slot i都在slot i发送反馈信息。如果在这4个slot中只接收到一个PDSCH，也需要slot i发送一个HARQ_ACK码本，该HARQ_ACK码本包含了4个slot内的所有PDSCH候选时机对应的反馈信息，如果在某个slot没有数据调度就填充NACK。如果在4个slot中仅有一个数据调度，而需要发送跟多时隙的PDSCH候选时机的反馈信息，例如4个时隙，每个时隙的每个PDSCH时机都对应H个比特的反馈信息，这样也会导致上行资源的浪费。为了解决上述技术问题，本申请实施例提供了如下解决方案。
请参考图7，图7是本申请实施例提供的一种信息处理方法的流程示意图。如图所示，本申请实施例中的步骤包括：
S702，网络设备向终端设备发送下行控制信息DCI，所述DCI用于调度物理下行共享信道PDSCH。
示例性的，DCI可以承载在PDCCH中。
S704，终端设备接收所述DCI，并根据所述DCI接收所述PDSCH。
S706，终端设备在第一时隙向所述网络设备发送N个码本。
S708，网络设备接收所述N个码本。
其中，所述N个码本包括一个第一码本和N-1个第二码本，所述第一码本中所述PDSCH对应的反馈比特位上为所述PDSCH的反馈信息，所述第二码本中的所述PDSCH对应的反馈比特位上为填充信息，所述N为大于等于2的整数。
需要特别说明的是，所述N个码本中，只包括一个第一码本，除第一码本之外的其它码本都是第二码本。例如，假设N等于5，也就是有5个码本，其实只有1个第一码本，其余的4个都为第二码本。
示例性的，第一时隙可以为一个时隙，该第一时隙可以由所述DCI指示，DCI中可以包括第二指示信息，该第二指示信息用于指示第一时隙。
例如，该第二指示信息指示一个K1的值，该K1的值用于指示该DCI调度的PDSCH所在的时隙与PDSCH的反馈信息所在的时隙(即第一时隙)之间间隔的时隙个数。具体的，如图8所示，在第slot i-2接收到PDSCH1、且调度该PDSCH1的DCI1指示K1＝2，则该PDSCH1的反馈信息在slot i反馈，也就是第一时隙为第i个时隙。在第slot i-1接收到PDSCH2、且调度该PDSCH2的DCI2指示K1＝1，则PDSCH2的反馈信息同样在slot i反馈，即第一时隙为第i个时隙。
终端设备在第一时隙向所述网络设备发送N个码本，其中码本个数N可以为终端设备和网络设备预先约定的值，或者可以是协议预定义的值，或者可以是网络设备发送指示信息指示的值。例如，协议规定一个时隙划分为N个时域区间，每个区间生成1个码本，则所述N即为时域区间的个数，即在一个时隙生成N个码本。再例如，协议规定N组DCI格式，或者N组RNTI，或者N组PDSCH的映射类型，N组PDSCH的调制编码方式，N组PDSCH的长度，其中，N组中每组对应一个码本，即在一个时隙生成N个码本，N的值即为组数。再例如，网络设备发送指示信息，该指示信息指示N＝3，该指示信息可以承载在DCI中或者是承载在高层信令中。本申请不做限定。
进一步，所述方法还包括:步骤S700a，网络设备可以向终端设备发送第一指示信息，第一指示信息用于指示码本模式。步骤S700b终端设备接收到第一指示信息。
进一步的，网络设备可以通过高层信令向终端设备发送第一指示信息。其中，高层信令可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)等等。
示例性的，所述码本模式为半静态码本模式。
进一步，所述方法还包括：步骤S705，终端设备生成N个码本。
需要说明的是，对于半静态码本模式，终端设备在一个slot生成N个码本，N为大于等于2的整数。具体N个码本中包括一个第一码本和N-1个第二码本。下面就如何确定第一码本和第二码本进行说明。
例如，所述DCI包括第三指示信息，所述第三指示信息用于指示所述N个码本中的所述第一码本。
例如，该第三指示信息指示K1的值，该K1的值用于指示PDSCH所在的时隙与PDSCH的反馈信息所在的时隙(即第一时隙)之间间隔的时隙个数。该第三指示信息还用于指示在第一时隙中PDSCH的反馈信息对应的PUCCH资源。终端设备根据第三指示信息，确定PDSCH的反馈信息对应的PUCCH资源所在的时域区间，称为为第一时域区 间，由于第一时隙中有N个时域区间，每个时域区间对应一个码本，则该第一时域区间对应的码本为第一码本，剩余的N-1个时域区间对应的码本为第二码本。
例如，如图8所示，第一时隙slot i包括2个时域区间，在每个时域区间可以生成一个码本，也就是N＝2。如果第三指示信息指示PDSCH的反馈信息对应的PUCCH资源在slot i的时域区间1，可以确定PDSCH的反馈信息在时域区间1对应的码本1中，也就是时域区间1对应的码本为第一码本，时域区间2对应的码本为第二码本。如果第三指示信息指示PDSCH的反馈信息对应的PUCCH资源在slot i的时域区间2，可以确定PDSCH的反馈信息在时域区间2对应的码本2中，也就是时域区间1对应的码本为第一码本，时域区间2对应的码本为第二码本。
可选的，该第三指示信息还可以直接指示N个码本中的第一个码本。例如，N＝2，第三指示信息包含1比特，取值为“0”指示第一码本为N个码本中的第一个码本。取值为“1”指示第一码本为N个码本中的第二个码本。终端设备接收DCI,根据第三指示信息确定第一码本，在第一时隙中N个码本中出第一码本之外的码本为第二码本。再例如，N＝4，第三指示信息包含2比特，取值为“00”指示第一码本为N个码本中的第一个码本。取值为“01”指示第一码本为N个码本中的第二个码本。
可选的，该第三指示信息还可以为调度PDSCH的DCI格式、调度PDSCH的DCI的加扰方式RNTI、PDSCH的长度、以及PDSCH的映射类型，PDSCH的调制编码方式等等，终端设备接收到第三指示信息之后，可以根据第三指示信息确定N个码本中的一个码本为第一码本。例如，调度PDSCH的DCI采用RNTI1加扰，该RNTI1属于N个RNTI组中的第一组，则该第一组RNTI对应的码本为第一码本，N个码本中剩余的N-1个码本为第二码本。例如，PDSCH的映射类型为映射类型A，该映射类型A属于N个映射类型组中的第一组，则该第一组对应的码本为第一码本，N个码本中剩余的N-1个码本为第二码本。
可选的，PDSCH对应的反馈比特位为根据所述PDSCH占用的时域资源确定的。具体来说，如前面半静态码本模式中的描述，PDSCH占用的时域资源在一个slot中可以对应于一个PDSCH候选时机，该PDSCH候选时机对应H个反馈比特位，根据PDSCH的时域资源对应的PDSCH候选时机可以确定出该PDSCH对应的反馈比特位。其中PDSCH候选时机对应的反馈比特位确定方法可以如前面所述，不再赘述。
例如，如图9所示，在第i-2个slot接收到PDSCH1、且调度该PDSCH1的DCI1指示K1＝2，则该PDSCH1的反馈信息在第i个slot反馈，也就是第一时隙为第i个时隙。在第i-1个slot接收到PDSCH2、且调度该PDSCH2的DCI2指示K1＝1，则PDSCH2的反馈信息同样在第i个slot反馈，即第一时隙为第i个时隙。之后网络设备需要在slot i生成2个码本。假设K1集合为{0，1，2，3}，从第i个slot开始往回推，按照K1集合，可以确定第(i-3)、(i-2)、(i-1)和(i)slot中所有PDSCH候选时机的反馈信息都需要在slot i进行反馈，每个PDSCH候选时机对应一个反馈比特位，且每个slot就一个PDSCH候选时机。因此在slot i发送的2个码本中每个码本中均包含4个反馈比特位。其中，第1个反馈比特位对应第(i-3)个slot的PDSCH候选时机，第2个反馈比特位对应第(i-2)个slot的PDSCH候选时机，……，第4个反馈比特位对应第i个slot的PDSCH候选时机。 PDSCH1占用的时域资源在slot i-2中，对应slot i-2中PDSCH候选时机，所以该PDSCH1对应的反馈比特位为4个反馈比特位中的第2个反馈比特位上。PDSCH2占用的时域资源在时域资源在slot i-1中，对应slot i-1中的PDSCH候选时机，所以该PDSCH 2对应的反馈比特位为4个反馈比特位中的第3个反馈比特位。
其中，PDSCH的反馈信息为根据所述PDSCH的译码结果确定的，当所述PDSCH的译码结果为正确时，所述PDSCH的反馈信息为ACK，当所述PDSCH的译码结果为错误时，所述PDSCH的反馈信息为NACK。网络设备接收到N个码本之后，当所述PDSCH的反馈信息为ACK，则所述PDSCH的译码结果为正确，当所述PDSCH的反馈信息为NACK时，所述PDSCH的译码结果为错误。
其中，所述填充信息为非真实的反馈信息，是预先约定的终端设备和网络设备都已知的信息，可以为NACK，也可以为ACK，本申请为NACK为例进行说明。
终端设备在第一时隙向所述网络设备发送N个码本，其中，所述N个码本包括一个第一码本和N-1个第二码本，所述第一码本中所述PDSCH对应的反馈比特位上为所述PDSCH的反馈信息，所述第二码本中的所述PDSCH对应的反馈比特位上为填充信息。网络设备可以在第一时隙接收该N个码本，从该N个码本中获取PDSCH的反馈信息。
例如，如图9所示，在下行的slot i-2(即第2个时隙)接收到第一个PDSCH1，并且调度该PDSCH1的DCI 1指示K1＝2，也就是在slot i反馈PDSCH1的反馈信息，并且终端设备根据前面所述的方法确定在slot i发送N＝2个码本，每个码本包含4个比特位，且根据前面的方法确定该PDSCH1对应的第一码本为码本2，则第二码本为码本1。且确定该PDSCH1对应的反馈比特位为4个比特位中的第2个反馈比特位。如果该PDSCH1译码结果正确，则在码本2中的第2个反馈比特位上为ACK，在码本1中的第2个反馈比特位上为填充信息NACK。又如，在下行的slot i-1(即第三个时隙)接收到第二个PDSCH2，也就是在slot i反馈PDSCH2的反馈信息，并且终端设备根据前面所述的方法确定在slot i发送N＝2个码本，每个码本包含4个比特位，且根据前面的方法确定该PDSCH2对应的第一码本为码本1，则第二码本为码本2。且确定该PDSCH1对应的反馈比特位为4个比特位中的第3个反馈比特位。因此在PDSCH2的译码结果为正确的情况下，在码本1中的第3个反馈比特位上为ACK，在码本2中的第3个反馈比特位上为填充信息NACK。由于在其他slot，即slot i-3，sloti中没有收到调度的PDSCH，因此在码本1和码本2的其他反馈比特为上填充信息NACK，最终得到码本1包含的信息为NNAN(即NACK,NACK,ACK,NACK)以及码本2包含的信息为NANN(即NACK,ACK,NACK,NACK)，假设用1表示ACK，0表示NACK，则码本1为“0010”，码本2为“0100”。同理0表示ACK，1表示NACK，则码本为“1101”，码本2为“1011”。
在本申请实施例中，在半静态码本模式下，一个时隙生成多个码本时，终端设备通过将接收到的PDSCH的反馈信息在N个码本中的一个码本中进行反馈，在剩余N-1个码本中PDSCH对应的反馈比特位填充NACK信息。这样，网络设备接收到N个码本之后，可知哪一个码本中是真实的反馈信息，并且可以确定哪些码本中是填充信息，从而可以避免网络设备和终端设备确定的反馈信息不一致，保证传输的可靠性。并且，由于填充信息是已知信息，如NACK信息，可以用于剩余N-1个码本的循环冗余校验(cyclic redundancy  check,CRC)，从而进一步提高剩余N-1个码本中反馈信息传输的可靠性。
在终端设备生成N个码本之后，针对每一个码本可以参照前述的1003步骤确定该每个码本对应的PUCCH资源，然后在每个码本对应的PUCCH资源上发送该码本。
可选的，在回退模式(falback)下，即DCI的预设格式为DCI format1_0，或者DCI的预设格式为用于在随机接入过程中进行数据调度的DCI格式时，当DCI中包含一个下行分配指示信息(downlink assignment indictor，DAI)的指示域取值为1、且该DCI由所述终端设备所在主小区(on the pcell)接收到时，第一码本中仅包括该DCI调度的PDSCH的反馈信息，而不包括其他PDSCH的反馈信息以及其他任何填充信息。通过减少反馈的码本的比特数，从而减少上行资源的开销。
例如，如图10所示，在下行的slot i-2(即第2个时隙)接收到第一个PDSCH1，并且调度该PDSCH1的DCI 1指示K1＝2，也就是在slot i反馈PDSCH1的反馈信息，并且终端设备根据前面所述的方法确定在slot i发送N＝2个码本，且根据前面的方法确定该PDSCH1对应的第一码本为码本2，则第二码本为码本1。且调度该DCI1为预设格式为DCI format1_0，且DCI1中包含一个下行分配指示信息DAI的指示域取值为1、且该DCI1由所述终端设备所在主小区(on the pcell)接收到时，如果该PDSCH1译码结果正确，则在码本2中仅包含一比特，且为NACK。又如，在下行的slot i-1(即第三个时隙)接收到第二个PDSCH2，也就是在slot i反馈PDSCH2的反馈信息，并且终端设备根据前面所述的方法确定在slot i发送N＝2个码本，且根据前面的方法确定该PDSCH2对应的第一码本为码本1，则第二码本为码本2。且调度该DCI2为预设格式为DCI format1_0，且DCI2中包含一个下行分配指示信息DAI的指示域取值为1、且该DCI2由所述终端设备所在主小区(on the pcell)接收到时，如果该PDSCH2译码结果正确，则在码本1中仅包含1比特，且为ACK。则因此最终得到码本1包含的信息为ACK以及码本2包含的信息为NACK，假设用1表示ACK，0表示NACK，则码本1为“1”，码本2为“0”。同理0表示ACK，1表示NACK，则码本为“0”，码本2为“1”。
需要说明的是，DAI承载在DCI中，该DAI用于指示在当前时刻，当前小区内网络设备发送的PDSCH累计数。简单可以理解为，是网络设备发送的第几个PDSCH。终端设备可以根据DCI确定是否有PDSCH丢失。例如，终端设备接收到2个DCI，第一个DCI指示DAI＝1，第二个DCI指示DAI＝3，但没有接收到包含DAI＝2的DCI。因此终端设备可以确定丢了一个PDSCH。
请参考图11，图11是本申请实施例提供的一种信息处理方法的流程示意图。如图所示，本申请实施例中的步骤包括：
S1102，网络设备向终端设备发送下行控制信息DCI，所述DCI用于调度物理下行共享信道PDSCH。
S1104，终端设备接收所述下行控制信息DCI，并根据所述DCI接收所述PDSCH。
S1106，终端设备在第一时隙向所述网络设备发送码本。所述码本中包含所述PDSCH的反馈信息。
S1108，网络设备接收所述码本。
可选地，在S1102之前，还包括S1100，终端设备接收网络设备发送的第一指示信息，第一指示信息用于指示码本模式。终端设备接收到第一指示信息之后，可以在不同的码本模式下生成不同的码本个数。
进一步的，网络设备可以通过高层信令向终端设备发送第一指示信息。其中，高层信令可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)等等。其中，当码本模式为动态码本模式时，终端设备可以在一个slot发送N个码本，当码本模式为半静态码本模式时，终端设备可以在一个slot发送1个码本，N为大于等于2的整数。所述码本中包含所述PDSCH的反馈信息。
需要说明的是，第一时隙的确定方法可以采用前述确定方法确定，在此不再赘述。
需要说明的是，对于动态码本模式，终端设备在一个slot中生成N个码本，N为大于等于2的整数。具体方式可以参考前面的在动态码本模式下生成多个码本的所述。不再赘述。
需要说明的是，对于半静态码本模式，终端设备可以在一个slot生成一个码本，具体的方式如前面半静态码本模式在一个时隙生成一个码本的介绍，不再赘述。
例如，如图12所示，通过上行slot i往回数，假设K1集合为{0，1，2，3}，确定出4个slot，将该4个slot的反馈信息生成一个码本，因此PDSCH1和PDSCH2的反馈信息在同一个码本中。在2个PDSCH的译码结果都为正确的情况下，在第2个反馈比特位上和第3个反馈比特位上均为ACK。由于在其他slot没有调度信息，因此在第1个反馈比特位上和第4个反馈比特位上填充NACK，最终得到码本包含的信息为NAAN(即NACK,ACK,ACK,NACK)，假设用1表示ACK，0表示NACK，则码本为“0110”，同理0表示ACK，1表示NACK，则码本为“1001”。
在本申请实施例中，在动态码本模式下生成多个码本可以实现不同业务的不同的可靠性需求。在半静态码本模式下，仅生成一个HARQ码本，可以减少上行资源的浪费。
在终端设备生成码本之后，针对每一个码本可以参照前述的1003步骤确定该每个码本对应的PUCCH资源，然后在每个码本对应的PUCCH资源上发送该码本。

进一步，所述方法还包括：步骤1305，终端设备生成N个码本。
具体N个码本的生成过程可以参照步骤S705中所述，只需要将PDSCH反馈信息合理替换为释放半静态调度PDSCH即可，不再赘述。
其中，半静态调度PDSCH是指，首先通过半静态信令配置一个PDSCH的发送周期，然后发送DCI触发PDSCH发送，从触发以后，以该周期进行PDSCH接收。如果网络设备要停止该半静态调度PDSCH，则发送一个DCI，该DCI指示释放该半静态调度的PDSCH，也就是不再以该周期进行PDSCH接收，或者说该半静态调度PDSCH不再有效，除非再次触发。
其中，所述N个码本包括一个第一码本和N-1个第二码本，所述第一码本中的所述释放半静态调度PDSCH对应的反馈比特位上为所述释放半静态调度PDSCH的反馈信息，所述第二码本中的所述释放半静态调度PDSCH对应的反馈比特位上为填充信息，所述N为大于等于2的整数。
其中，所述释放半静态调度PDSCH的反馈信息为根据所述释放半静态调度PDSCH的执行结果确定的，当所述释放半静态调度PDSCH的执行结果为成功时，所述释放半静态调度PDSCH的反馈信息为ACK，当所述释放半静态调度PDSCH的执行结果为失败时，所述释放半静态调度PDSCH的反馈信息为NACK。其中，所述填充信息为非真实的反馈信息，可以为NACK，也可以为ACK，本申请为NACK为例进行说明。

S1406，终端设备在第一时隙向所述网络设备发送码本。所述码本中包含所述释放半静态调度的PDSCH的反馈信息。
S1408，网络设备接收所述码本。
其中，半静态调度PDSCH是指，首先通过半静态信令配置一个PDSCH的发送周期，然后发送DCI触发PDSCH发送，从触发以后，以该周期进行PDSCH接收。如果网络设备要停止该半静态调度PDSCH，则发送一个DCI，该DCI指示释放该半静态调度的PDSCH，也就是不再以该周期进行PDSCH接收，或者说该半静态调度PDSCH不再有效，除非再次触发。
可选地，在S1402之前，还包括S1400，终端设备接收网络设备发送的第一指示信息，第一指示信息用于指示码本模式。终端设备接收到第一指示信息之后，可以在不同的码本模式下生成不同的码本个数。
进一步的，网络设备可以通过高层信令向终端设备发送第一指示信息。其中，高层信令可以是指高层协议层发出的信令，高层协议层为物理层以上的至少一个协议层。其中，高层协议层可以包括以下协议层中的至少一个：媒体接入控制(medium access control，MAC)层、无线链路控制(radio link control，RLC)层、分组数据会聚协议(packet data  convergence protocol，PDCP)层、无线资源控制(radio resource control，RRC)层和非接入层(non access stratum，NAS)等等。
其中，当码本模式为动态码本模式时，终端设备可以在一个slot发送N个码本，N为大于等于2的整数。具体方式可以参考前面的在动态码本模式下生成多个码本的所述。不再赘述。
当码本模式为半静态码本模式时，终端设备可以在一个slot发送1个码本，所述码本中包含所述PDSCH的反馈信息。具体的方式如前面半静态码本模式在一个时隙生成一个码本的介绍，不再赘述。
其中，所述释放半静态调度PDSCH的反馈信息为根据所述释放半静态调度PDSCH的执行结果确定的，当所述释放半静态调度PDSCH的执行结果为成功时，所述释放半静态调度PDSCH的反馈信息为ACK，当所述释放半静态调度PDSCH的执行结果为失败时，所述释放半静态调度PDSCH的反馈信息为NACK。其中，所述填充信息为非真实的反馈信息，可以为NACK，也可以为ACK，本申请为NACK为例进行说明。
