目前5G新空口(new radio，NR)的下行传输支持半持续性调度(semi-persistent scheduling,SPS)的物理下行共享信道(physical downlink shared channel,PDSCH)和动态调度的PDSCH。对于动态调度的PDSCH，一个PDSCH的传输由一个物理下行控制信道(physical downlink control channel,PDCCH)调度。对于下行的数据传输，混合自动重传(hybrid automatic repeat request,HARQ)是一种高效的传输机制。一方面，通过重传可以极大提高下行数据传输的可靠性，另一方面，终端设备反馈HARQ的肯定应答(acknowledgement,ACK)/否定应答(negative acknowledgement，NACK)信息，只有反馈NACK时，网络设备才需要进行重传，提高了数据传输效率。在NR设计中，支持两种HARQ-ACK码本配置，即动态HARQ码本(dynamic HARQ codebook)和半静态HARQ码本(semi-static HARQ codebook)。目前在半静态HARQ码本生成中，存在较大的冗余，使得半静态HARQ码本占用的资源较多，造成资源的浪费，并且降低了半静态HARQ码本中反馈的HARQ-ACK的可靠性。

为便于理解本申请实施例，下面先对本申请涉及到的几个概念进行简单介绍。
时间单元和时域符号：
基站和终端设备用于无线通信的时域资源可以划分为多个时间单元。并且，在本申请实施例中，多个时间单元可以是连续的，也可以是某些相邻的时间单元之间设有预设的间隔，本申请实施例并未特别限定。
在本申请实施例中，对一个时间单元的长度不做限定。例如，1个时间单元可以是一个或多个子帧；或者，也可以是一个或多个时隙；或者，也可以是一个或多个符号。其中，一个子帧是1ms，一个时隙在正常循环前缀情况下包括14个符号，在扩展循环前缀的情况下，包括12个符号。
在本申请的实施例中，符号也称为时域符号，可以是正交频分复用(orthogonal  frequency division multiplexing，OFDM)符号，也可以是单载波频分多址(single carrier frequency division multiple access，SC-FDMA)符号，其中SC-FDMA又称为带有转换预编码的正交频分复用(orthogonal frequency division multiplexing with transform precoding，OFDM with TP)。
本申请实施例中的终端设备可以指用户设备、接入终端、用户单元、用户站、移动站、移动台、远方站、远程终端、移动设备、用户终端、终端、无线通信设备、用户代理或用户装置。终端设备还可以是蜂窝电话、无绳电话、会话启动协议(Session Initiation Protocol，SIP)电话、无线本地环路(Wireless Local Loop，WLL)站、个人数字处理(Personal Digital Assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备、可穿戴设备，未来5G网络中的终端设备或者未来演进的公用陆地移动通信网络(Public Land Mobile Network，PLMN)中的终端设备等，本申请实施例对此并不限定。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通讯(Global System of Mobile communication，GSM)系统或码分多址(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)系统中的基站(NodeB，NB)，还可以是LTE系统中的演进型基站(Evolutional NodeB，eNB或eNodeB)，还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及未来5G网络中的网络设备或者未来演进的PLMN网络中的网络设备等，本申请实施例并不限定。
目前5G新空口(new radio，NR)的下行传输支持半持续性调度(semi-persistent scheduling,SPS)的物理下行共享信道(physical downlink shared channel,PDSCH)和动态调度的PDSCH。对于下行的数据传输，混合自动重传(hybrid automatic repeat request,HARQ)是一种高效的传输机制。一方面，通过重传可以极大提高下行数据传输的可靠性，另一方面，终端设备反馈HARQ的肯定应答(acknowledgement,ACK)/否定应答(negative acknowledgement，NACK)信息，只有反馈NACK时，网络设备才需要进行重传，提高了数据传输效率。
动态的PDSCH可以理解为一个PDSCH由一个PDCCH来调度，每一个PDSCH的时频位置可能是不相同的，具体的时频位置通过每一个PDSCH对应的PDCCH来指示；每一个PDSCH对应的ACK/NACK反馈时机也可能是不同的，具体的反馈时机也是通过每一个PDSCH对应的PDCCH来指示。这种PDSCH也可以称为动态的PDSCH，或者有调度信息的PDSCH。
SPS PDSCH可以理解为一次配置周期使用的模式，例如，网络设备可以通过发送一个激活PDCCH去激活多个SPS PDSCH的传输，这个激活PDCCH可以用于指示第一个SPS PDSCH的时域位置、第一个SPS PDSCH所在的时隙、与SPS PDSCH对应的ACK或者NACK的反馈信息的时频位置等，另外网络设备还会通过高层信令发送配置信息配置SPS PDSCH的周期，结合这些信息，终端设备可以确定接收SPS PDSCH的位置以及SPS PDSCH对应的ACK或者NACK的反馈信息的位置。
在NR设计中，支持两种HARQ-ACK码本模式。具体的，网络设备可以通过发送配置 信息，指示此时采用哪种HARQ-ACK码本模式来生成HARQ-ACK码本。其中，HARQ-ACK码本可以理解为在某个上行时间单元上需要反馈的、与PDSCH对应的ACK/NACK的一种排列，包含2层含义：第一：HARQ-ACK码本包含哪些PDSCH的ACK/NACK。第二：这些PDSCH的ACK/NACK在码本中的排列顺序。也就是说，将需要在同一个上行时间单元内发送的多有的PDSCH的反馈信息ACK/NACK按照一定的顺序排列为一串连续的比特，就形成了HARQ-ACK码本。两种HARQ-ACK码本模式包括动态码本(Dynamic codebook)模式和半静态码本(Semi-static codebook)模式。不同的码本模式中HARQ-ACK码本的生成方式不同。
对于半静态HARQ-ACK码本，又称Type 1 HARQ Codebook。半静态码本确定的过程分为以下步骤：
首先，终端设备确定发送ACK/NACK反馈信息的时隙为第i个时隙。具体时隙i的确定是根据PDSCH对应的PDCCH确定的。PDCCH中会指示预配置的或者与预定义的时域资源表格中的一行。时域资源表格包括多行，每一行可以包括一个PDSCH时域资源分配索引、与该PDSCH时域资源分配索引对应的K0、S、L的值、PDSCH映射类型。S指示一个时隙内时域资源的起始(start)符号编号。L指示该时隙内时域资源的持续的符号个数。L(length)是表示数据信道所占的符号个数，也可以称为数据信道的持续的符号个数，或者也可以称为数据信道的时域长度。L是从S开始的连续的符号的个数。K0的含义为PDCCH到PDSCH的所在的时隙之间间隔的时隙个数。S和L可以联合编码为一个开始和长度指示值(start and length indicator value，SLIV)参数，SLIV可以用于指示PDSCH所占的开始符号和符号个数。终端设备根据PDCCH指示的PDSCH时域资源分配索引，便可以确定该PDSCH调度的PDSCH所在的时隙以及在该时隙内的时域资源位置等信息。例如，假设终端设备在第N个时隙接收到PDCCH，K0的值为1，则该PDCCH调度的PDSCH的所在的时隙为第N+1个时隙。对于PDSCH映射类型，PDSCH映射类型主要是确定PDSCH的解调参考信号(demodulation reference signal，DMRS)的时域符号位置，还可以用来确定PDSCH所有合理的开始位置、持续时间等。PDSCH映射包括两种类型：类型A(type A)或者类型B(type B)。type A表示第一个DMRS的位置在slot的第3或者第4个符号，type B表示第一个DMRS的位置在数据开始的第一个符号。
下面结合表1的例子说明时域资源表格。
表1
Figure PCTCN2020087821-appb-000001
如表1所示的时域表格，假设终端设备在第1个时隙接收到PDCCH，PDCCH可以携带PDSCH时域资源分配索引，假设该索引为0，终端设备接到PDCCH后，根据索引0，可以确定PDSCH的所在的时隙为时隙2，并且，PDSCH是在时隙2中的符号编号为2的符号至符 号编号为5的符号上传输。
应理解，表1只是示例性的，不应该对时域资源表格产生任何的限制。
假设PDSCH所在的时隙为时隙n，该PDCCH中还会指示一个K1值，K1用于指示PDSCH到对应ACK/NACK反馈的时隙偏移值。终端设备可以根据K1值和PDSCH所在的时隙为时隙n，确定与PDSCH对应ACK/NACK反馈所在的时隙为n+K1，即在时隙为n+K1上使用物理上行控制信道(physical uplink control channel，PUCCH)来反馈ACK/NACK。
假设时隙为n+K1为时隙i。之后，终端设备根据网络设备发送的配置信息获取K1的可能取值K1集合(K1set)，基于上述信息，终端设备确定所有要在第i个时隙发送反馈信息的所有的PDSCH所在的时隙，即确定所有要在第i个时隙发送反馈信息的所有的候选PDSCH接收时机(PDSCH candidate occasion)组成的候选PDSCH接收时机集合(occasion set for candidate PDSCH receptions)。然后再根据该集合，按时机(occasion)顺序得到反馈的HARQ-ACK比特。对于候选PDSCH接收时机集合中没有实际PDSCH调度的occasion，反馈的HARQ-ACK比特中填充否定应答NACK。最后，将该所有候选PDSCH接收时机对应的ACK/NACK按照PDSCH candidate occasion在时域上从前到后的顺序，以及该所有时隙在时域上从前到后的顺序串联，串联生成一个HARQ-ACK码本。最终生成半静态HARQ-ACK码本。
下面结合具体的例子说明半静态HARQ-ACK码本的生成过程。
假设网络设备通过配置信息RRC为终端设备配置K1集合为{1,2,3,4}。网络设备通过PDCCH1调度了PDSCH1，如图2所示，图2所示的为根据K1集合确定半静态码本反馈HARQ-ACK的一个例子。PDCCH1中携带的下行控制信息(downlink control information，DCI)指示K1为3。终端设备根据DCI指示K1为3，确定PDSCH1到反馈PDSCH1对应的ACK/NACK的资源为PUCCH1，假设PDSCH1所在的时隙为时隙n，则PUCCH1所在的时隙为时隙n+3。在PUCCH1上反馈HARQ-ACK之前，终端设备需要首先根据K1集合{1,2,3,4}得到候选PDSCH接收时机集合(occasion set for candidate PDSCH receptions)。根据K1集合，从第n+3个时隙往回推，即第n+3个时隙反馈的将是第n+2个时隙、第n+1个时隙、第n个时隙、第n-1个时隙这4个时隙中收到的所有PDSCH对应的ACK/NACK。终端设备确定的候选PDSCH接收时机集合包括时隙n+2、时隙n+1、时隙n以及时隙n-1。即在时隙n+3中需要反馈时隙n-1、时隙n、时隙n+1以及时隙n+2上的PDSCH的ACK/NACK。然后再根据该集合，按PDSCH时机(occasion)顺序得到反馈的HARQ-ACK比特。对于该集合中没有实际的PDSCH调度的occasion，反馈的HARQ-ACK比特中填充否定应答NACK。假设每个时隙上只能调度一个PDSCH，且对于每个PDSCH只反馈1比特的ACK/NACK，则时隙n+3中的PUCCH1需要反馈4比特的ACK/NACK。
图3为根据K1集合确定半静态HARQ码本反馈HARQ-ACK的另一个例子。网络设备通过配置信息为终端设备配置K1集合为{1,2,3,4}。网络设备先后通过三个不同的PDCCH调度了如图3所示的三个PDSCH,三个PDSCH分别为PDSCH1、PDSCH2、PDSCH3，且三个不同的PDCCH都指示PUCCH1用于反馈PDSCH1、PDSCH2、PDSCH3的HARQ_ACK。PDSCH1位于时隙n上，PDSCH2位于时隙n+1上，PDSCH3位于时隙n+3上。假设PDSCH1对应K1为4，则PDSCH1的ACK/NACK的资源为PUCCH11所在的时隙为时隙n+4。在PUCCH1上反馈HARQ-ACK之前，终端设备需要首先根据K1集合{1,2,3,4}确定候选 PDSCH接收时机集合(occasion set for candidate PDSCH receptions)。终端设备确定的候选PDSCH接收时机集合包括时隙n+3、时隙n+2、时隙n+1以及时隙n。即在时隙n+4中需要反馈时隙n、时隙n+1、时隙n+2以及时隙n+3上的PDSCH的ACK/NACK。假设每个时隙都只能调度一个PDSCH，并且对于每个PDSCH只反馈1比特的ACK/NACK，由于时隙n+2上没有调度的PDSCH，因此，时隙n+2对应的反馈信息为NACK。时隙n+4中的PUCCH1需要反馈4比特的ACK/NACK。
应理解，图2和图3中的例子中都假设每个时隙都只调度一个PDSCH，并且对于每个PDSCH都只需要反馈1比特ACK/NACK。如果一个时隙可调度多于一个PDSCH，和/或，一个PDSCH需要反馈多于1比特的n比特ACK/NACK，则对于候选PDSCH接收时机集合中的每个无PDSCH调度的位于相同时隙或不同时隙的occasion，在相应HARQ-ACK反馈中填充n比特NACK。
还应理解，图2和图3所示的例子中都基于FDD系统，即上行传输和下行传输分别属于不同载波。如果在TDD系统中，候选PDSCH接收时机集合的除了确定考虑K1集合，还要考虑PDSCH候选时域资源与该时隙的符号在上下行属性上无冲突，即需要保证该时隙内的至少一个PDSCH候选时域资源中，不能含有上行符号。如果该时隙内的所有PDSCH候选时域资源中都含有上行符号，该时隙会被排除在候选PDSCH接收时机集合之外。
目前，对于如何降低终端设备的功耗成为亟需解决的问题。减少PDCCH检测是其中一个重要手段。其中，动态改变PDCCH检测周期是减少PDCCH检测的一种技术。该技术可达到的效果是：在数据传输需求较小，或者没有数据传输需求时，网络设备指示终端设备采用较大的PDCCH检测周期，则相应的PDCCH检测时机(occasion)次数较少，达到节省功耗的效果。当出现数据传输需求或者数据传输需求较大时，网络设备指示终端设备减小PDCCH检测周期，则终端设备会相应增加PDCCH检测时机，以提供更多机会给网络设备发送指示数据调度的PDCCH，从而减小调度和数据传输时延，提高数据传输速率。
对于PDCCH检测周期较大的情形，由于PDSCH是由PDCCH调度的，可能出现较多的不可能有PDCCH调度的PDSCH occasion。如图4所示，图4是根据K1集合确定半静态HARQ码本反馈HARQ-ACK的又一个例子。图4所示的例子中，PDCCH检测周期为8个时隙，K1集合为{1,2,3,4,5,6,7,8}，假设PDCCH1用于调度PDSCH1，PDCCH1中的DCI指示的K0为1，K1为6。根据K1集合{1,2,3,4}确定候选PDSCH接收时机集合包括时隙n-1至时隙n+6这8个时隙上的候选PDSCH接收时机。由于PDCCH检测周期为8个时隙，在候选PDSCH接收时机集合包括的8个时隙中，只有时隙n+1上可能出现PDSCH1，其他的7个时隙上是不可能出现PDSCH，其他的7个时隙可以称为PDSCH无效时机(invalid PDSCH occasion)。这种情况下，根据上述的半静态HARQ码本的生成过程，会有大量的NACK填充是对应PDSCH无效时机的。如图4所示的，假设一个PDSCH时机对应1比特的ACK/NACK，则PDCCH1上的半静态HARQ码本中8比特HARQ-ACK反馈中有7比特都是无效NACK比特，这7比特无效NACK均没有对应的PDSCH传输。这样会导致反馈HARQ-ACK的PUCCH资源开销较大，并且填充的NACK降低了实际需要反馈的HARQ-ACK的码率，
有鉴于此，本申请提供了一种半静态码本生成的方法，结合调度PDSCH的动态改变的PDCCH的检测时机，确定候选PDSCH接收时机，候选PDSCH接收时机与动态变化的PDCCH检测时机对应。根据候选PDSCH接收时机，确定半静态HARQ码本。可以降低半 静态HARQ码本中无效的NACK比特，从而提高了半静态HARQ码本的码率，降低了反馈半静态HARQ码本的PUCCH资源的开销，提高半静态HARQ码本的可靠性，提高通信效率。
下面结合图5详细说明本申请提供的半静态码本生成的方法，图5是本申请一个实施例的半静态码本生成的方法200的示意性交互图，该方法200可以应用在图1所示的场景中，当然也可以应用在其他通信场景中，本申请实施例在此不作限制。
应理解，在本申请实施例中，以终端设备和网络设备作为执行方法200的执行主体为例，对方法200进行说明。作为示例而非限定，执行方法200的执行主体也可以是应用于终端设备的芯片和应用于网络设备的芯片。
如图5所示，该方法200包括S210至S230。
S210，网络设备向终端设备发送指示信息，该指示信息用于动态改变PDCCH的检测时机。相应的，终端设备接收该指示信息。
S220，终端设备根据该PDCCH的检测时机和第一时隙偏移值集合，确定在第一PUCCH资源上发送的HARQ_ACK对应的候选PDSCH接收时机，该PDCCH用于调度该PDSCH的传输，该第一时隙偏移值集合包括的时隙偏移值用于指示PDCCH与PDSCH之间的时隙偏移值。
S230，终端设备根据该候选PDSCH接收时机，确定在该第一PUCCH上发送的HARQ_ACK的半静态HARQ码本。
具体而言，对于PDCCH调度PDSCH传输的情况下，PDCCH的检测时机的周期会存在比较大的情况。PDCCH的检测时机可以理解为PDCCH所在的时域资源。网络设备可以在预配置或者预定义的PDCCH时域资源上发送PDCCH，终端设备在预配置或者预定义的PDCCH时域资源检测PDCCH。可选的，可以预配置或者预定义PDCCH的多个搜索空间集合(search space set，SS set))，不同的搜索空间集合对应不同的PDCCH检测周期和检测时机。多个搜索空间集合对应的PDCCH检测时机的并集即为终端设备的PDCCH检测时机。例如，对于一个搜索空间集合，可以预配置或者预定义PDCCH的周期集合，该周期集合包括多个PDCCH的周期。假设PDCCH的周期集合为{1,2,4,8,10,20}，单位为时隙，第一个PDCCH在时隙n发送，则对应于不同的PDCCH周期，会有不同的PDCCH检测时机。例如，对于PDCCH周期为2，则PDCCH检测时机为时隙n、时隙n+2、时隙n+4、时隙n+6等等，即每隔两个时隙为一个PDCCH检测时机。对于PDCCH周期为8，则PDCCH检测时机为时隙n、时隙n+8、时隙n+16、时隙n+24等等，即每隔8个时隙为一个PDCCH检测时机。在相同时间长度内，PDCCH的周期不同，则PDCCH的检测时机也是不同的，终端设备可能检测到的PDCCH个数也是不同的，从而PDCCH调度的PDSCH的接收时机也是不同的。在S210中，网络设备可以通过指示信息向终端设备指示动态改变PDCCH的检测时机。动态改变PDCCH的检测时机可以理解为PDCCH的周期或者检测时机是变化的。例如，在某些场景中，该指示信息可以指示PDCCH的周期集合中较小的PDCCH周期，网络设备会根据该较小的PDCCH周期向终端设备发送PDCCH。在另一些场景中，该指示信息可以指示PDCCH的周期集合中较大的PDCCH周期，网络设备会根据该较大的PDCCH周期向终端设备发送PDCCH。每一个PDCCH用于调度PDSCH的传输。在需要改变PDCCH的发送周期时，网络设备会向终端设备发送该指示信息，用于指示动态改变该PDCCH的检测时机或者周期。
在S220中。终端设备会根据该指示信息指示的PDCCH的检测时机和第一时隙偏移值集合，并结合K1集合，确定在第一PUCCH资源上发送的HARQ_ACK对应的候选PDSCH接收时机。该第一时隙偏移值集合包括的时隙偏移值用于指示PDCCH与PDSCH之间的时隙偏移值。第一时隙偏移值集合可以理解为上述的K0集合。K0集合可以是预配置或者预定义的，包括一个或者多个K0。K0用于确定PDCCH所在的时隙与该PDCCH调度的PDSCH之间的时域偏移值。K1集合可以是预配置的或者预定义的。K1集合包括的时隙偏移值用于指示发送HARQ_ACK的PUCCH资源所在的时隙与该HARQ_ACK对应的PDSCH的时隙偏移值。K1集合可以为下述第二时隙偏移值集合。例如，假设K0集合为{1,2,3}，PDCCH所在的时隙为时隙n，则该PDCCH调度的PDSCH可能出现的时隙位置为时隙n+1、时隙n+2或者时隙n+3。最终该PDCCH调度的PDSCH出现的时隙由该PDCCH中指示的某一个K0确定。并且，该PDCCH还可以指示PDSCH在某一个时隙中的时域资源位置。例如，PDCCH可以指示上述表1中所示的某一行，进而可以确定该PDCCH调度的PDSCH所在的时隙以及在该时隙中的时域资源位置。该PDCCH中还可以指示某一个K1值，该K1值指示PDCCH所在的时隙与第一PUCCH资源所在的时隙偏移值。终端设备可以根据K1值，确定第一PUCCH资源所在的时隙。终端设备可以先根据K1集合和第一PUCCH资源所在的时隙，确定在第一PUCCH资源上发送的HARQ_ACK对应的所有可能的候选PDSCH接收时机，然后根据PDCCH的检测时机和第一时隙偏移值集合，在确定出的所有可能的候选PDSCH接收时机中确定出在第一PUCCH资源上发送的HARQ_ACK对应的候选PDSCH接收时机。由于候选PDSCH接收时机是根据PDCCH的检测时机和第一时隙偏移值集合确定的，候选PDSCH接收时机只包括可能出现PDCCH调度的PDSCH接收时机，不包括不可能有PDCCH调度的PDSCH接收时机，不可能有PDCCH调度的PDSCH接收时机也可以称为PDSCH无效时机，即候选PDSCH接收时机不包括PDSCH无效时机。每个候选PDSCH接收时机对应一个PDCCH检测时机。PDSCH接收时机与动态变化的PDCCH检测时机对应。PDCCH检测时机不同，确定出的PDSCH接收时机也是不同的。
在S230中，终端设备会根据确定出的候选PDSCH接收时机，确定在该第一PUCCH上发送的HARQ_ACK的半静态HARQ码本。由于候选PDSCH接收时机不包括PDSCH无效时机，与PDSCH无效时机对应的NACK可以称为无效的NACK比特。终端设备最终确定的半静态HARQ码本中不包括无效的NACK比特。
本申请提供的半静态码本生成的方法，由于候选PDSCH接收时机是根据动态变化的PDCCH检测时机和第一时隙偏移值集合确定的。候选PDSCH接收时机只包括可能出现PDCCH检测时机调度的PDSCH接收时机，避免了候选PDSCH接收时机包括PDSCH无效时机。根据该候选PDSCH接收时机确定半静态HARQ码本，可以降低半静态HARQ码本中无效的NACK比特，从而提高了半静态HARQ码本的码率，降低了反馈半静态HARQ码本的PUCCH资源的开销，提高半静态HARQ码本的可靠性。尤其对于PDCCH周期比较大的情况下，可以很大程度上提高半静态HARQ码本的可靠性，提高通信效率。
可选的，在本申请实施例中，网络设备也可以根据PDCCH的检测时机和第一时隙偏移值集合，确定在第一PUCCH资源上接收的HARQ_ACK对应的候选PDSCH接收时机。然后根据该候选PDSCH接收时机，确定在该第一PUCCH上接收的半静态HARQ码本。 其具体的过程可以参考上述对于S220和S230的描述，为了简洁，这里不再赘述。
可选的，作为一种可能的实现方式，上述的指示信息可以包括：激活或者去激活该PDCCH对应的搜索空间集合、该PDCCH的检测周期或者该PDCCH检测跳过信息中的至少一个，其中，该PDCCH对应的搜索空间集合包括该PDCCH的检测周期。其中，PDCCH对应的搜索空间集合可以包括PDCCH的周期。
具体而言，可以为该PDCCH预配置或者定义一个或者多个搜索空间集合，或者为该PDCCH预配置或者定义多个PDCCH检测周期，或者，为该PDCCH预配置或者定义多种PDCCH检测跳过(PDCCH monitor skipping)信息(信号)。每一个搜索空间集合中可以包括一个或者多个PDCCH的检测周期。网络设备可以在该指示信息中指示激活或者去激活该PDCCH对应的搜索空间集合。激活的PDCCH对应的搜索空间集合可以理解为利用该激活的PDCCH对应的搜索空间集合包括的PDCCH周期去确定该PDCCH的检测时机。去激活的PDCCH对应的搜索空间集合可以理解为网络设备不会利用该去激活的PDCCH对应的搜索空间集合包括的PDCCH周期发送该PDCCH。终端设备根据该指示信息包括的激活或者去激活的搜索空间集合，结合与该搜索空间集合关联的控制资源集，便可以确定该PDCCH的检测时机。如果一个搜索空间集合中包括一个或者多个PDCCH的检测周期，并且这个搜索空间集合是被激活的，进一步的，网络设备还可以指示利用该激活的搜索空间集合中包括的哪一个PDCCH周期。可选的。对于一个搜索空间集合，还可以配置与每一个PDCCH检测周期对应的周期内连续检测的时隙个数和/或时隙内PDCCH的检测符号。终端设备可以根据与每一个PDCCH检测周期对应的周期内PDCCH连续检测的时隙个数和/或时隙内PDCCH的检测符号，确定PDCCH的检测时机。
可选的，该指示信息还可以包括为该PDCCH预配置或者预定义的多个PDCCH检测周期中的某一个PDCCH检测周期，终端设备根据该指示信息指示的PDCCH检测周期，可以确定该PDCCH的检测时机。或者，该指示信息还可以包括PDCCH检测跳过信息，PDCCH检测跳过信息可以理解相邻两次PDCCH检测之间的时间间隔，例如，假设PDCCH检测跳过信息为PDCCH检测跳过的时隙为5个，则表明相邻两次检测PDCCH之间间隔5个时隙，即PDCCH的周期的为5。终端设备可以根据上述的指示信息包括的内容，确定PDCCH的检测时机。
终端设备根据该指示信息包括的内容确定PDCCH的检测时机，可以提高确定出的PDCCH的检测时机的准确率，提高确定PDCCH的检测时机的效率。
应理解，该指示信息除了包括上述的用于确定PDCCH的检测时机的信息之外，还可以包括其他用于确定PDCCH的检测时机的信息。例如，该指示信息可以直接指示PDCCH的检测时机等。本申请实施例中对于网络设备如何向终端设备指示动态改变PDCCH的检测时机的方式不作限制。
还应理解，网络设备也可以根据上述的指示信息包括的用于确定PDCCH的检测时机的信息，或者其他用于确定PDCCH的检测时机的信息确定该PDCCH的检测时机。
如图6所示，图6是本申请一些实施例中的半静态码本生成的方法的示意性交互图，在一些实施例中，在图6所示的方法步骤的基础上，该方法200还可以包括S211。
S211，终端设备根据第二时隙偏移值集合和该第一PUCCH资源所在的时隙，确定与该第一PUCCH资源所在的时隙对应的时间单元集合，该第二时隙偏移值集合包括的时隙 偏移值用于指示该第一PUCCH资源所在的时隙与该时间单元集合中的时间单元的时隙偏移值。
上述的S220可以包括：
S221，终端设备根据该PDCCH的检测时机和该第一时隙偏移值集合，在该时间单元集合中确定该候选PDSCH接收时机。
图6中所示的S210以及S230的描述可以参考上述对S210以及S230的描述，为了简洁，这里不再赘述。
在S211中，终端设备可以先根据第二时隙偏移值集合和该第一PUCCH资源所在的时隙，确定与该第一PUCCH资源所在的时隙对应的时间单元集合。第二时隙偏移值集合可以理解为上述的K1集合。K1集合可以是预配置的或者预定义的。K1集合包括的时隙偏移值用于指示发送HARQ_ACK的PUCCH资源所在的时隙与该HARQ_ACK对应的PDSCH的时隙偏移值。对于第一PUCCH资源而言，K1集合可以用于指示第一PUCCH资源所在的时隙与该时间单元集合中的时间单元的时隙偏移值。这里的时间单元可以理解为一个时隙，即一个时间单元的长度可以等于一个时隙。或者时间单元也可以理解为一个微时隙或者迷你时隙等，即一个时隙内也可以包括多个时间单元。一个时间单元可以对应一个可能的候选PDSCH接收时机，可能的候选PDSCH接收时机可以是有PDCCH调度的候选PDSCH接收时机，也可以是没有PDCCH调度的PDSCH无效时机。例如，假设K1集合为{1,2,3,4}，第一PUCCH资源所在的时隙为时隙n，则与第一PUCCH资源所在的时隙对应的时间单元集合包括时隙n-4、时隙n-3、时隙n-2以及时隙n-1，一个时隙为与一个时间单元。对于时隙n-4、时隙n-3、时隙n-2以及时隙n-1中的任何一个时隙上，可能会有PDCCH调度的PDSCH，也可能没有PDCCH调度的PDSCH。即时隙n-4、时隙n-3、时隙n-2以及时隙n-1中可能包括无效的PDSCH。在确定了该时间单元集合后，也就确定了所有可能的候选PDSCH接收时机。
上述的S220：根据PDCCH的检测时机和第一时隙偏移值集合，确定在第一PUCCH资源上发送的HARQ_ACK对应的候选PDSCH接收时机，可以包括：
S221，根据该PDCCH的检测时机和该第一时隙偏移值集合，在该时间单元集合中确定该候选PDSCH接收时机。
具体而言，在确定了该时间单元集合后，可以根据该PDCCH的检测时机和该第一时隙偏移值集合，在该时间单元集合中剔除不可能有PDCCH调度的PDSCH的时间单元。例如，对于该时间单元集合中的某一个时间单元，根据该第一时隙偏移值集合，从该时间单元所在的时隙向前推算，如果该从该时间单元所在的时隙向前推算得到一个或者多个时隙中存在PDCCH检测时机，则该时间单元内可能会有PDCCH调度的PDSCH，即该时间单元可以视为一个候选PDSCH接收时机。如果对于该时间单元集合中的某一个时间单元，从该时间单元所在的时隙向前推算得到一个或者多个时隙中均不存在PDCCH检测时机，则该时间单元内不可能会有PDCCH调度的PDSCH，则该时间单元可以视为一个PDSCH无效时机，需要将该时间单元排除。在该时间单元集合内将无效的PDSCH无效时机剔除后，剩余的时间单元即为候选PDSCH接收时机。
可选的。除了利用PDCCH的检测时机和第一时隙偏移值集合，在上述的时间单元集合中确定该候选PDSCH接收时机之外，进一步的，如果PDSCH的传输利用的是TDD通 信系统，还需要保证每个候选PDSCH接收时机对应的一个或者多个候选PDSCH时域资源中的至少一个PDSCH时域资源均为下行符号。即还需要保证每个候选PDSCH接收时机对应的PDSCH时域资源中至少有一个PDSCH时域资源可以传输PDSCH。每个PDSCH接收时机可以对应一个或者多个候选PDSCH时域资源。例如，表1所示的例子中，每个PDSCH接收时机可以对应至少4种资源分配索引，每种资源分配索引对应不同的PDSCH时域资源(即SLIV)。也就是说，每个PDSCH接收时机至少对应4中PDSCH时域资源，需要保证PDSCH时域资源中的至少一个PDSCH时域资源包括的符号均为下行符号。
下面将结合图7所示的例子进行说明。图7所示为根据第二时隙偏移值集合、第一时隙偏移值集合以及PDCCH检测时机确定候选PDSCH接收时机的示意图。
图7中，假设PDCCH检测周期为4个时隙，K1集合(第二时隙偏移值集合)为{1,2,3,4,5,6,7,8}，K0集合(第一时隙偏移值集合)为{1,2}，第一PUCCH资源所在时隙为时隙n+8。则根据第二时隙偏移值集合和该第一PUCCH资源所在的时隙，确定出的与第一PUCCH资源所在的时隙对应的时间单元集合包括：时隙n至时隙n+7这8个时隙，每个时隙可以视为一个时间单元。其中，假设这8个时隙中第一个PDCCH检测时机位于时隙n+1，则第二个PDCCH检测时机位于时隙n+5。首先，在时隙n至时隙n+7这8个时间单元中，对于每个时间单元，根据K0集合，确定出不可能有PDCCH调度的PDSCH所在的时间单元。例如，对于时隙n+7，结合K0集合，确定出的PDCCH检测时机可能存在的时隙为时隙n+5和时隙n+6。如果时隙n+5和时隙n+6中的任何一个时隙上只要存在PDCCH检测时机，则时隙n+7为一个候选PDSCH接收时机。如果时隙n+5和时隙n+6这两个时隙上均不存在PDCCH检测时机，则时隙n+7不是一个候选PDSCH接收时机，时隙n+7可以视为PDSCH无效时机。而第二个PDCCH检测时机位于时隙n+5，证明时隙n+7为一个候选PDSCH接收时机。利用类似的方法，依次确定时隙n至时隙n+6这些时间单元是否为候选PDSCH接收时机。最终确定出的候选PDSCH接收时机包括：时隙n+2、时隙n+3、时隙n+6、时隙n+7这四个时隙为候选PDSCH接收时机。假设每个时隙上只能调度一个PDSCH，且对于每个PDSCH只反馈1比特的ACK/NACK。则根据确定的候选PDSCH接收时机，在该第一PUCCH上发送的HARQ_ACK的半静态HARQ码本只需要4比特，并且这4比特的码本均对应的是可能有PDCCH调度的候选PDSCH接收时机。如果这四个候选PDSCH接收时机其中有某一个或者多个候选PDSCH接收时机实际上并没有接收到PDSCH，则在半静态HARQ码本相应的位置填充一个或者多个NACK比特。对于这四个候选PDSCH接收时机中最终实际上接收到PDSCH的候选PDSCH接收时机，根据调度的PDSCH对应的一个或两个传输块(transmission block，TB)，或者根据调度的PDSCH对应的一个或多个码块组(code block group,CBG)的译码对错，生成对应的一个或多个HARQ-ACK比特。
可选的，如果PDSCH的传输利用的是TDD通信系统，则还需进一步的确定时隙n+2、时隙n+3、时隙n+6、时隙n+7这四个候选PDSCH接收时机中，每个候选PDSCH接收时机对应的一个或者多个候选PDSCH时域资源中的至少一个PDSCH时域资源均为下行符号。如果这四个候选PDSCH接收时机有一个或者多个候选PDSCH接收时机不满足上述的条件，则还需要在这四个候选PDSCH接收时机排除不满足上述条件的候选PDSCH接收时机，剩下的满足条件的候选PDSCH接收时机才是最终在第一PUCCH上发送的半静 态HARQ码本对应的候选PDSCH接收时机。
应理解，图7所示的例子中假设每个时隙都只调度一个PDSCH，每个候选PDSCH接收时机都只需要反馈1比特ACK/NACK。如果一个时隙可调度多于一个PDSCH，和/或，一个候选PDSCH接收时机需要反馈多于1比特的n比特ACK/NACK，则对于候选PDSCH接收时机中位于相同时隙或不同时隙的occasion，在相应HARQ-ACK反馈中填充n比特NACK。
本申请提供的半静态码本的生成方法，先根据第二时隙偏移值集合和第一PUCCH资源所在的时隙，确定与该第一PUCCH资源所在的时隙对应的时间单元集合，该时间单元集合包括的每一个时间单元可以视为一个可能的候选PDSCH接收时机，然后根据该PDCCH的检测时机和该第一时隙偏移值集合，在该时间单元集合中排除不可能有PDCCH调度的时间单元(或者可以称为无效时间单元)。或者，在该时间单元集合中排除不可能有PDCCH调度的时间单元以及时间单元包括的时域资源不满足下行传输的时间单元。将不满足条件的时间单元排除，剩余的时间单元即为候选PDSCH接收时机。从而避免了候选PDSCH接收时机包括PDSCH无效时机的现象的出现，根据该候选PDSCH接收时机确定半静态HARQ码本，可以降低半静态HARQ码本中无效的NACK比特，从而提高了半静态HARQ码本的码率，降低了反馈半静态HARQ码本的PUCCH资源的开销，提高半静态HARQ码本的可靠性。
应理解，网络设备也可以根据第二时隙偏移值集合和该第一PUCCH资源所在的时隙，确定与该第一PUCCH资源所在的时隙对应的时间单元集合。然后根据该PDCCH的检测时机和该第一时隙偏移值集合，在该时间单元集合中确定该候选PDSCH接收时机。其具体的描述可以参考上述对于S211和S221的描述，为了简洁，这里不再赘述。
可选的，在本申请一些可能的实现方式中，上述的PDCCH检测时机对应的PDCCH承载DCI，并且，该DCI用于调度单播类型的PDSCH。单播类型的PDSCH可以理解为发送给某一个或者单个终端设备的PDSCH，终端设备在接收到单播类型的PDSCH后，需要对该PDSCH进行NACK/ACK反馈。
可选的，用于调度单播类型的PDSCH的DCI可以对应小区无线临时网络标识(cell radio network temporary identifier，C-RNTI)加扰，即用于调度单播类型的PDSCH的DCI的循环冗余校验码(cyclic redundancy check，CRC)是利用C-RNTI进行加扰的。或者，用于调度单播类型的PDSCH的DCI对应调制编码方案小区无线网络临时标识(modulation coding scheme cell radio network temporary identifier，MCS-C-RNTI)加扰，即用于调度单播类型的PDSCH的DCI的CRC也可以利用MCS-C-RNTI进行加扰。或者，用于调度单播类型的PDSCH的DCI对应配置调度无线网络临时标识加扰(Configured Scheduling radio network temporary identifier，CS-RNTI)，即用于调度单播类型的PDSCH的DCI的CRC也可以利用CS-RNTI进行加扰。当终端设备检测到PDCCH携带的DCI是利用上述的几种RNTI进行加扰的时，则终端设备可以确定该PDCCH调度的是单播类型的PDSCH。进一步的，可以根据该PDCCH的检测时机和第一时隙偏移值集合，确定候选PDSCH接收时机，并根据候选PDSCH接收时机生成半静态HARQ码本。避免了半静态HARQ码本对应非单播类型的PDSCH，可以提高半静态HARQ码本的可靠性，降低了反馈半静态HARQ码本的PUCCH资源的开销。
应理解，除了利用上述的几种RNTI加扰用于调度单播类型的PDSCH的DCI之外， 还可以利用其他类型的RNTI的加扰用于调度单播类型的PDSCH的DCI。本申请实施例对于加扰用于调度单播类型的PDSCH的DCI的RNTI不作限制。
可选的，在本申请一些可能的实现方式中，该第二时隙偏移值集合包括的时隙偏移值的个数小于或者等于4。
例如，第二时隙偏移值集合可以是预配置或者预定义的，预配置的或者预定义的第二时隙偏移值集合包括时隙偏移值的个数可以小于一个阈值，例如，该阈值可以为4，或者2，或者为3等。可选的，该阈值小于8。
例如，第二时隙偏移值集合可以为{1}，或者为{2}，或者为{3}，或者为{4}，或者为{5}，或者为{6}，或者为{7}，或者为{8}。
又例如，第二时隙偏移值集合可以为{1,2}，或者为{3,4}，或者为{5,6}，或者为{7,8}。
又例如，第二时隙偏移值集合可以为{1,2,3}，或者为{3,4,5}，或者为{6,7,8}。
又例如，第二时隙偏移值集合可以为{4,8}，或者为{3,7}，或者为{2,6}，或者为{7,8}。
又例如，第二时隙偏移值集合可以为{1,3,5,7}，或者为{2,4,6,8}。
可选的，网络设备可以利用PDCCH携带的DCI中某些字段向终端设备指示与PDCCH对应的时隙偏移值是预配置或者预定义的第二时隙偏移值集合包括的哪一个时隙偏移值。例如，假设第二时隙偏移值集合为{4,8}，可以利用DCI中的“PDSCH到HARQ反馈时序”这3比特指示字段中的最高有效比特为0时，指示的时隙偏移值为4，最高有效比特为1时，指示的K1为8。该指示字段其余两个比特无指示意义。对于第二时隙偏移值集合包括其他两个时隙偏移值的情况，也可以用类似的方法向终端设备设备指示与PDCCH对应的是哪一个时隙偏移值。
又例如，假设第二时隙偏移值集合为{2,4,6,8}，可以利用DCI中的“PDSCH到HARQ反馈时序”这3比特指示字段中的最高两位有效比特为00时，则指示的时隙偏移值为2，最高两位有效比特为01时，则指示的时隙偏移值为4，最高两位有效比特为10时，则指示的时隙偏移值为6，最高两位有效比特为11时，则指示的时隙偏移值为8。该指示字段其余一个比特无指示意义。对于第二时隙偏移值集合包括其他4个时隙偏移值的情况，也可以用类似的方法向终端设备设备指示具体使用的哪一个时隙偏移值。
本申请提供的半静态码本的生成方法，通过限制第二时隙偏移值集合包括的时隙偏移值的个数，在降低半静态HARQ码本中无效的NACK比特的基础上，可以降低半静态HARQ码本的比特数。进一步的提高半静态HARQ码本的可靠性。
应理解，上述对于第二时隙偏移值集合包括的元素的个数以及每个元素的取值只是示例性。不应该对本申请中第二时隙偏移值集合包括的时隙偏移值的个数和时隙偏移值的取值产生限制。例如，第二时隙偏移值集合包括的时隙偏移值的个数还可以为5个等。
还应理解，网络设备除了利用上述的DCI中某些字段向终端设备指示与PDCCH对应的时隙偏移值是预配置或者预定义的第二时隙偏移值集合包括的哪一个时隙偏移值之外，还可以通过其他方式通知终端设备与PDCCH对应的时隙偏移值是预配置或者预定义的第二时隙偏移值集合包括的哪一个时隙偏移值。例如，网络设备可以通过配置信息通知终端设备与PDCCH对应的时隙偏移值等。
在本申请实施例中，预配置可以包括网络设备通过高层信令配置和物理层信令配置。本申请中的高层信令例如可以包括无线资源控制信令(radio resource control，RRC)、媒 体接入控制(medium access control，MAC)控制元素(control element，CE)、无线链路控制(radio link control，RLC)信令等，物理层信令例如可以包括DCI等。
可选的，在本申请的一些可能的实现方式中，该指示信息还用于指示该HARQ_ACK采用半静态HARQ码本。终端设备接收到该指示信息后，便可以确定需要生成半静态HARQ码本。
应理解，上述的指示信息也可以通过高层信令或者物理层信令通知给终端设备。
应理解，在本申请的各个实施例中，第一、第二等只是为了表示多个对象是不同的。例如第一时隙偏移值集合和第二时隙偏移值集合只是为了表示出不同的时隙偏移值集合。而不应该对时隙偏移值集合的本身和包括的时隙偏移值的数量等产生任何影响，上述的第一、第二等不应该对本申请的实施例造成任何限制。
还应理解，本申请实施例中的方式、情况、类别以及实施例的划分仅是为了描述的方便，不应构成特别的限定，各种方式、类别、情况以及实施例中的特征在不矛盾的情况下可以相结合。
还应理解，在本申请的实施例中涉及的各种数字编号仅为描述方便进行的区分，并不用来限制本申请的实施例的范围。上述各过程的序号的大小并不意味着执行顺序的先后，各过程的执行顺序应以其功能和内在逻辑确定，而不应对本申请实施例的实施过程构成任何限定。
还应理解，上述只是为了帮助本领域技术人员更好地理解本申请实施例，而非要限制本申请实施例的范围。本领域技术人员根据所给出的上述示例，显然可以进行各种等价的修改或变化.例如，上述方法200中某些步骤可以是不必须的，或者可以新加入某些步骤等。或者上述任意两种或者任意多种实施例的组合。这样的修改、变化或者组合后的方案也落入本申请实施例的范围内。
