Description

信息反馈方法以及装置 技术领域
本申请实施例涉及通信技术领域。
背景技术
物理下行共享信道(Physical Downlink Shared Channel,PDSCH)是无线通信系统中物理下行信道的一种，用于承载下行数据。PDSCH可以是通过下行控制信息(downlink control information，DCI)调度的。用于调度PDSCH的DCI中至少包括用于指示该PDSCH的资源的信息。在目前的新无线(new radio，NR)系统中，定义了多种用于调度PDSCH的DCI格式(format)，例如DCI format 1_0、DCI format 1_1、DCI format 1_2，不同DCI format的DCI包括的具体信息和/或大小是不一样的，以满足不同的调度需求。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
在目前的NR系统中，一个DCI只能调度一个PDSCH。发明人发现，在一些情况下，对终端设备来说，这种调度方式可能存在DCI(PDCCH)监听负担高的问题，进而导致设备的复杂度及耗电量也高。
例如，目前如何支持NR系统在更高频率(52.6GHz以上)上工作正在研究中，更高频率上的数据传输将面临更严重的相位噪声等问题。因此，为了克服相位噪声等问题，可能需要采用更大的子载波间隔(e.g.240kHz，480kHz，960kHz等)以支持在更高频率上的数据传输，而更大的子载波间隔意味着更短的符号长度。如果沿用NR目前的帧结构设计(其中一个时隙包括14个符号)，更大的子载波间隔也就意味着更短的时隙长度。另一方面，若要采用上述调度方式支持终端设备(UE)在每个时隙内都能接收至少一个PDSCH，则UE需要在每个时隙都监听DCI。这样，在采用上述更大的子载波间隔的情况下，由于时隙长度变短，UE在单位时间内的DCI监 听次数将增加。也就是说，UE的DCI监听负担将增加，UE的实现复杂度和耗电量也将相应增加。
针对上述问题的至少之一，本申请实施例提供一种信息反馈方法，信息接收方法及装置。
根据本申请实施例的一个方面，提供一种信息反馈装置，该装置包括：
第一接收单元，其用于接收用于调度物理下行共享信道(PDSCH)的下行控制信息(DCI)，该DCI用于指示至少两个(M个)第一PDSCH的时域资源分配信息；
第二接收单元，其用于接收至少一个(N个)第二PDSCH；
第一发送单元，其用于发送第一HARQ-ACK信息，该第一HARQ-ACK信息包括该至少一个(N个)第二PDSCH的第二HARQ-ACK信息。
根据本申请实施例的另一个方面，提供一种信息接收装置，该装置包括：
第二发送单元，其用于向终端设备发送用于调度物理下行共享信道(PDSCH)的下行控制信息(DCI)，该DCI用于指示至少两个(M个)第一PDSCH的时域资源分配信息；
第三发送单元，其用于向终端设备发送至少一个(N个)第二PDSCH；
第四接收单元，其用于接收终端设备发送发送的第一HARQ-ACK信息，该第一HARQ-ACK信息包括该至少一个(N个)第二PDSCH的第二HARQ-ACK信息。
根据本申请实施例的另一个方面，提供一种通信系统，该系统至少包括终端设备和网络设备，其特征在于，
该终端设备接收该网络设备发送的用于调度物理下行共享信道(PDSCH)的下行控制信息(DCI)，该DCI用于指示至少两个(M个)第一PDSCH的时域资源分配信息；
该终端设备接收该网络设备发送的至少一个(N个)第二PDSCH；
该终端设备向该网络设备发送第一HARQ-ACK信息，该第一HARQ-ACK信息包括该至少一个(N个)第二PDSCH的第二HARQ-ACK信息。
本申请实施例的有益效果之一在于：通过一个DCI可以调度多个PDSCH，并通过一种新的HARQ-ACK信息反馈方法支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息，由此减轻终端设备的DCI监听负担，降低耗电量以及复杂度。

在本申请实施例中，不同的PDSCH承载的传输块(例如1个或2个传输块)不同，因此，下文中“多个PDSCH”或“至少两个PDSCH”都是指承载不同传输块的不同PDSCH。更具体的，不同的PDSCH承载的传输块对应不同的HARQ进程，其 中，不同的HARQ进程由不同的HARQ进程标识。
在现有方案中，一个DCI只能调度一个PDSCH，不能调度多个PDSCH，本申请实施例通过一个DCI可以调度多个PDSCH，其中，各个PDSCH承载不同的传输块(非重复)，并支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息，由此减轻终端设备的DCI监听负担，降低耗电量以及复杂度。
以下结合各个实施例进行说明。
第一方面的实施例
本申请实施例提供一种信息反馈方法，从终端设备侧进行说明。
图2是本申请实施例的信息反馈方法的一示意图，如图2所示，该方法包括：
201，该终端设备接收用于调度物理下行共享信道(PDSCH)的下行控制信息(DCI)，该DCI包括用于指示至少两个(M个)第一PDSCH的时域资源的第一信息域；
202，该终端设备接收至少一个(N个)第二PDSCH；
203，该终端设备发送第一HARQ-ACK信息，该第一HARQ-ACK信息包括该至少一个(N个)第二PDSCH的第二HARQ-ACK信息。
在一些实施例中，用于调度PDSCH的DCI的DCI格式(DCI format)可以是DCI format 1_0、DCI format 1_1、DCI format 1_2，或者另外引入的新的DCI format等，本申请实施例并不以此作为限制。
在一些实施例中，用于调度PDSCH的DCI可以由小区无线网络临时标识,(Cell-RadioNetworkTemporaryIdentifier，C-RNTI)，编码调制方案C-RNTI(MCS-C-RNTI)，配置调度RNTI(CS-RNTI)，临时C-RNTI(TC-RNTI)，系统信息RNTI(SI-RNTI)，随机接入RNTI(RA-RNTI)，随机接入响应中的MsgB-RNTI，寻呼RNTI，(P-RNTI)，或者另外引入的新的RNTI等加扰，本申请实施例并不以此作为限制。
在一些实施例中，该第一PDSCH是该DCI指示的PDSCH，也可以称为指示的PDSCH(indicated PDSCH)或名义PDSCH(nominal PDSCH)，该至少两个(M个)第一PDSCH(以下简称M个第一PDSCH，其中，M大于等于2)的时域资源连续或者不连续，不同的第一PDSCH的时域符号数相同或不同，各个第一PDSCH的时 域资源在一个时隙中或不在一个时隙中，本申请实施例并不以此作为限制。
在一些实施例中，网络设备侧可以通过高层信令配置PDSCH与PDCCH的时域关系列表(或者称为第一时域资源分配表)，例如，网络设备发送RRC消息，该RRC消息中包括第一配置信息，该第一配置信息包括至少一个第一信息元素，其中，一个第一信息元素用于配置PDSCH与PDCCH的时域关系，例如，该第一配置信息是PDSCH-TimeDomainResourceAllocationList，该第一信息元素是PDSCH-TimeDomainResourceAllocation，第一配置信息例如包括在pdsch-ConfigCommon或pdsch-Config中。该第一时域资源分配表包括至少一行PDSCH时域资源的配置，一行PDSCH时域资源的配置对应上述第一信息元素。
在一些实施例中，该DCI包括用于指示至少两个(M个)第一PDSCH的时域资源的第一信息域,该第一信息域例如是时域资源分配(Time domain resource assignment)字段，该第一信息域包含第五数量(E)个比特，该第五数量可以是配置的或预定义的，本申请实施例并不以此作为限制，该第五数量个比特对应的十进制值即为该第一信息域的值，该第一信息域的值可以用来表示该DCI指示该第一配置信息中的第几个第一信息元素，例如该第一信息域的值为0，对应指示该第一配置信息中的第一个第一信息元素，该第一信息域的值为1，对应指示该第一配置信息中的第二个第一信息元素，以此类推，此处不再一一举例。
以下进一步说明如何根据该第一信息域和该第一配置信息确定指示的至少两个(M个)第一PDSCH(以下简称M个第一PDSCH，其中，M大于等于2)。
在一些实施例中，在上述第一信息域用于指示至少两个(M个)第一PDSCH的时域资源的情况下，该第一信息域的值对应一个第一信息元素，该一个第一信息元素用于配置M个第一PDSCH与承载该DCI的PDCCH的时域关系。
在一些实施例中，该第一信息元素可以包括至少一个用于配置PDSCH的时域资源(或者说PDSCH的符号，e.g.包括PDSCH的起始符号和长度(SLIV))的第二信息元素(e.g.PDSCH-Allocation或startSymbolAndLength)，各个第一信息元素包括的第二信息元素数量相同或不同，换句话说，该第一信息元素至多可以包含第一预定值(e.g.maxNrofMultiplePDSCHs)个第二信息元素，该第一预定值是预定义的且大于1；该第二信息元素用于配置一个PDSCH的时域资源，该第一信息域的值对应一个第一信息元素，该一个第一信息元素用于配置M个第一PDSCH与承载该DCI的PDCCH 的时域关系，也就是说，该一个第一信息元素中包括至少两个(M个)第二信息元素，每个第二信息元素分别用于配置一个第一PDSCH的时域资源。
在上述实施例中，该第二信息元素包括PDSCH映射类型(mappingType)以及起始符号和长度(startSymbolAndLength)配置，即每个第一PDSCH的时域资源应用各自的(与其对应的第二信息元素中的)PDSCH映射类型以及起始符号和长度配置来确定；例如，该第一配置信息使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2020121335-appb-000001
或者该第二信息元素包括起始符号和长度配置(startSymbolAndLength)，该第一信息元素中包括PDSCH映射类型配置(mappingType)，即每个第一PDSCH的时域资源应用各自的(与其对应的第二信息元素中的)起始符号和长度配置，但应用相同的PDSCH映射类型配置来确定，例如，该第一配置信息使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2020121335-appb-000002
在一些实施例中，该第一信息元素可以包括用于配置第六数量(F)的信息(e.g.nrOfPDSCHs)，该第六数量表示该第一信息元素对应的第一PDSCH的个数。在上述第一信息域用于指示至少两个(M个)第一PDSCH的时域资源的情况下，该第一信息域的值对应一个第一信息元素，该一个第一信息元素用于配置M个第一PDSCH与承载该DCI的PDCCH的时域关系，该一个第一信息元素中包括的第六数量F即为上述M。
在上述实施例中，该第一信息元素包括用于配置PDSCH与PDCCH之间的时隙偏移(K0)的信息(e.g.k0)。例如，k0指示F个第一PDSCH的起始时域位置与PDCCH之间的时隙偏移，或者说，F个第一PDSCH中的第一个PDSCH与PDCCH之间的时隙偏移。例如，假设用于承载上述DCI的PDCCH在时隙n发送，则F个第一PDSCH的起始时域位置在时隙n+K0，或者说F个第一PDSCH中的第一个PDSCH在时隙n+K0发送。另外，该第一信息元素还可以包括用于配置PDSCH映射类型的信息(e.g.mappingType)和/或用于配置PDSCH的时域资源(或者说PDSCH的符号，e.g.包括PDSCH的起始符号和长度(SLIV))的信息(e.g.startSymbolAndLength)，例如，该第一配置信息使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2020121335-appb-000003
其中，SEQUENCE表示对应信息的有序集合，SIZE表示对应SEQUENCE集合中元素的数量，INTEGER()和ENUMERATED()表示对应信息的取值类型和取值范围，具体可以参考ASN.1语法，此处不再一一赘述。
在上述实施例中，可以应用相同的PDSCH映射类型以及起始符号和长度确定F个第一PDSCH时域资源；或者应用该PDSCH映射类型和起始符号和长度确定上述F个第一PDSCH中的第一个第一PDSCH时域资源，剩余(F-1)个第一PDSCH的时域资源与该第一个第一PDSCH的时域资源长度相同并顺序映射在连续的符号上。
在一些实施例中，该第一信息元素可以包括第七数量(G)的信息(e.g.nrOfSlots)， 该第四数量表示该第一信息元素对应的时隙个数。该第一信息域的值对应一个第一信息元素，该一个第一信息元素用于配置M个第一PDSCH与承载该DCI的PDCCH的时域关系，该一个第一信息元素中包括的第四数量G即为上述M。
在上述实施例中，该第一信息元素包括用于配置PDSCH与PDCCH之间的时隙偏移(K0)的信息(e.g.k0)。例如，k0指示G个第一PDSCH的起始时域位置与PDCCH之间的时隙偏移，或者说，G个第一PDSCH中的第一个PDSCH与PDCCH之间的时隙偏移。例如，假设用于承载上述DCI的PDCCH在时隙n发送，则G个第一PDSCH的起始时域位置在时隙n+K0，或者说G个第一PDSCH中的第一个PDSCH在时隙n+K0发送，另外，该第一信息元素还可以包括用于配置PDSCH映射类型的信息(e.g.mappingType)和/或用于配置PDSCH的时域资源(或者说PDSCH的符号，e.g.包括PDSCH的起始符号和长度(SLIV))的信息(e.g.startSymbolAndLength)，可以应用相同的PDSCH映射类型以及起始符号和长度确定G个第一PDSCH时域资源。
例如，该第一配置信息使用抽象语法标记ASN.1数据格式可以表示为：
Figure PCTCN2020121335-appb-000004
在一些实施例中，网络设备还可以通过高层信令配置多个PDSCH与PDCCH之间的时隙偏移值(K 0)，即M个第一PDSCH的时域资源应用各自的(K 0)信息确定各自所在时隙。例如，该PDSCH与PDCCH之间的时隙偏移(K 0)的信息可以被包含在第二信息元素中，M个第一PDSCH的时域资源应用各自的(K 0)信息确定各自所在时隙，此处不再一一举例。
以上以网络设备侧通过高层信令配置PDSCH与PDCCH的时域关系列表(或者称为PDSCH时域资源分配列表)为例进行说明，但本申请实施例并不以此作为限制，例如，还可以通过预定义PDSCH与PDCCH的时域关系列表来配置多个PDSCH的时域资源，其一行的配置类似于上述一个第一信息元素的配置，此处不再赘述。
以下进一步说明如何确定至少一个(N个)第二PDSCH。
在一些实施例中，该第二PDSCH即为实际调度的PDSCH(e.g.scheduled PDSCH,actual PDSCH)，上述第一PDSCH即为第二PDSCH，N＝M，N和M都大于等于2，换句话说DCI指示的M个第一PDSCH即为实际调度的N个第二PDSCH。
在一些实施例中，终端设备可以根据以下信息中的至少一个确定该至少一个(N个)第二PDSCH：半静态配置的传输方向(或者说用于半静态配置传输方向的信息)，配置的PRACH资源，用于动态调度上行传输的信息或用于动态配置传输方向的信息，配置的无效符号，是否跨时隙。以下分别说明。
在一些实施例中，半静态配置即基站通过小区级别/用户专用级别的高层信令进行配置。用于半静态配置传输方向的信息例如为tdd-UL-DL-ConfigurationCommon或tdd-UL-DL-ConfigurationDedicated，一个时间单元(e.g.符号，时隙，子帧)的传输方向可以半静态配置为上行(uplink)，下行(downlink)或灵活(flexible),其中，未被上述信息显式配置为上行或下行的时间单元即为被配置为灵活的时间单元。在根据半静态配置的传输方向确定N个第二PDSCH时，在该第一PDSCH的至少一个符号被半静态配置为上行时(即不能接收下行的PDSCH)，该第一PDSCH不作为第二PDSCH，换句话说，终端设备不接收该第一PDSCH。例如，针对多个时隙中的一个时隙(假设一个时隙中有一个第一PDSCH)，如果该时隙中由上述DCI指示的第一PDSCH的至少一个符号被半静态配置为上行时，终端设备不接收该时隙中的第一PDSCH。图3A是至少一个第二PDSCH示意图，如图3A所示，假设图上第2个时隙中的第一PDSCH有一个符号被半静态配置为上行，而图上其他符号没有被配置为上行，该第一PDSCH不作为第二PDSCH。
在一些实施例中，在根据配置的PRACH资源确定N个第二PDSCH时，在该第一PDSCH的至少一个符号被配置了PRACH，和/或该第一PDSCH的至少一个符号是配置的PRACH之前的第三数量(该第三数量例如是预定义的)个符号(例如称为间隔符号)中的符号时，该第一PDSCH不作为该第二PDSCH，图3B是该至少一个第二PDSCH示意图，如图3B所示，图上第2个时隙中的第一PDSCH中至少一个符号被配置了PRACH且该第一PDSCH的至少一个符号是配置的PRACH之前的第三数量(该数量例如是预定义的)个符号(例如称为间隔符号)中的符号，该第一PDSCH不作为第二PDSCH，换句话说，终端设备不接收该第一PDSCH。
在一些实施例中，传输方向可以被动态配置传输方向的信息配置为上行(uplink)， 下行(downlink)或灵活(flexible),其中，未被上述信息显式配置为上行或下行的时间单元即为被配置为灵活的时间单元，在根据动态调度上行传输的信息或动态配置传输方向的信息确定N个第二PDSCH时，在该第一PDSCH中至少一个符号被该信息动态调度了上行传输或传输方向被该信息动态配置为上行时，该第一PDSCH不作为该第二PDSCH，换句话说，终端设备不接收该第一PDSCH。上述各实施方式与上述半静态配置的实施方式，此处不再一一赘述。
在上述实施例中，用于动态调度上行传输的信息(例如DCI format 0_0或DCI format 0_1或DCI format 0_2的DCI)或用于动态配置传输方向的信息(例如DCI format 2_0的DCI)在该DCI之前发送，否则，UE不根据该信息确定第二PDSCH，或者说在确定至少一个第二PDSCH时不考虑该信息。
或者，在上述实施例中，用于动态调度上行传输的信息(例如DCI format 0_0或DCI format 0_1或DCI format 0_2的DCI)或用于动态配置传输方向的信息(例如DCI format 2_0的DCI)在该DCI的一定时间(该一定时间例如是预定义的)之前发送，否则，UE不根据该信息确定第二PDSCH，或者说在确定至少一个第二PDSCH时不考虑该信息。
在一些实施例中，在根据配置的无效符号确定至少一个第二PDSCH时，在该第一PDSCH的至少一个符号被配置为无效时(即不能接收下行的PDSCH)，该第一PDSCH不作为第二PDSCH，上述各实施方式与上述半静态配置的实施方式，此处不再一一赘述。
在一些实施例中，该终端设备还可以根据以下信息中的至少一个确定无效符号：半静态配置的传输方向(或者说用于半静态配置传输方向的信息)，配置的PRACH资源，动态调度上行传输的信息或动态配置传输方向的信息，配置的无效符号。例如上述半静态配置的上行符号可以确定为是无效符号，和/或配置了PRACH资源的符号可以确定为是无效符号，和/或配置了PRACH之前的第十数量(该第十数量例如是预定义的)个符号(例如称为间隔符号)中的符号可以确定为是无效符号，和/或被用于动态调度上行传输的信息动态调度了上行传输的符号可以确定为是无效符号，和/或被用于动态配置传输方向的信息配置为上行的符号可以确定为是无效符号，和/或被配置为无效的符号可以确定为是无效符号。如果第一PDSCH包含确定的无效符号，那么该第一PDSCH不作为第二PDSCH，具体实施方式如前所述，此处不再赘述。
上述确定至少一个(N个)第二PDSCH或确定无效符号的因素可以单独实施，也可以结合实施，本申请实施例并不以此作为限制。
在一些实施例中，N的值不超过上述各第一信息元素对应的第一PDSCH的数量的最大数，或者N的值不超过M。图3C是该至少一个第二PDSCH示意图，假设N的值不超过M，如图3C所示，该M值为4，则第二PDSCH的数量N最多为4。此处仅为示例说明，本申请实施例并不以此作为限制。
以下进一步说明该DCI可以包含的其他的信息域。
在一些实施例中，该DCI还可以包括第五信息域，，该第五信息域可以是HARQ确认(HARQ-ACK)时机指示(i.e.PDSCH-to-HARQ_feedback timing indicator)字段，该第五信息域用于指示HARQ确认(HARQ-ACK)信息的反馈时机k，或者该DCI也可以不包括该第五信息域，该终端设备接收高层信令配置的第二配置信息(例如dl-DataToUL-ACK或dl-DataToUL-ACKForDCIFormat1_2 for DCI format 1_2)，该第二配置信息用于指示HARQ确认(HARQ-ACK)信息的反馈时机k。
在一些实施例中，该终端设备在索引为n+k的时隙(时隙n+k)发送第一HARQ-ACK信息，其中，索引为n的时隙(时隙n)是该至少两个(M个)第一PDSCH的结束时隙或该至少两个(M个)第一PDSCH中的最后一个第一PDSCH的结束时隙，n和k是大于0的整数，即最后一个第一PDSCH的结束时隙为n(PDSCH的下行结束时隙n'对应的上行时隙索引为n)，k为第一HARQ-ACK信息的反馈时隙与时隙n的偏移，PDSCH的下行结束时隙n'与其对应的上行时隙索引为n关系可以根据上下行子载波间隔确定，具体可以参考现有技术，此处步骤赘述。图4A和图4B是第一HARQ-ACK信息反馈时隙示意图，如图4A所示，M第一PDSCH即为实际调度的N个第二PDSCH，最后一个第一PDSCH结束的下行时隙为n，时隙n+k发送第一HARQ-ACK信息，如图4B所示，最后一个第一PDSCH不作为第二PDSCH，最后一个第一PDSCH结束的下行时隙为n，时隙n+k发送第一HARQ-ACK信息，而不是将最后一个第二PDSCH结束的下行时隙看作n。
在一些实施例中，第一HARQ-ACK信息由PUCCH或PUSCH承载。该至少一个(N个)第二PDSCH的第二HARQ-ACK信息由同一PUCCH或PUSCH承载。
在一些实施例中，终端设备在一个物理上行资源上反馈的HARQ-ACK信息的整体可以称为HARQ-ACK码本，该终端设备采用半静态HARQ-ACK码本发送该第一 HARQ-ACK信息，或者说，该第一HARQ-ACK信息是半静态HARQ-ACK码本，半静态码本也称为类型一HARQ-ACK码本(Type-1HARQ-ACK codebook)。该码本的大小不随实际的数据调度情况动态变化，而是根据预配置(e.g.高层信令配置的)或预定义的参数确定。
以下进一步说明如何生成该第一HARQ-ACK信息(即如何生成该码本)。
在一些实施例中，该码本可以包括一个或多个服务小区的HARQ-ACK信息比特。以下仅针对如何确定一个服务小区的HARQ-ACK信息比特进行说明。在该码本包括多个服务小区的HARQ-ACK信息比特的情况下，各个服务小区的HARQ-ACK信息比特的确定方式与前述一个服务小区的HARQ-ACK信息比特的确定方式相同。
在一些实施例中，该码本包括第一数量个(A个)候选PDSCH接收时机对应的HARQ-ACK信息比特，该第一数量是自然数。其中，该第一数量个(A个)候选PDSCH接收时机对应同一服务小区(i.e.前述一个服务小区)，即，该第一数量个(A个)候选PDSCH接收时机属于服务小区的候选PDSCH接收时机集合M A,c。
在现有技术中，由于仅支持一个DCI调度一个PDSCH，目前的HARQ-ACK信息反馈方法没有考虑一个DCI调度多个PDSCH的情况，不支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息。本申请实施例中，一个DCI可以调度多个PDSCH，为了支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息，提供了一种HARQ-ACK信息反馈方法，其中，该至少一个(N个)第二PDSCH的第二HARQ-ACK信息可以对应同一个候选PDSCH接收时机，或者对应不同的候选PDSCH接收时机。以下分别进行说明。
I.至少一个(N个)第二PDSCH的第二HARQ-ACK信息可以对应同一个候选PDSCH接收时机
图5是生成码本方法一示意图，如图5所示，该方法包括：
501，确定第一数量个候选PDSCH接收时机；
502，确定与第一数量个候选PDSCH接收时机对应的HARQ-ACK信息比特。
在一些实施例中，在第一时域资源分配表的一行(即一个第一信息元素)对应第四数量(D)个PDSCH时域资源(例如包括多个第二信息元素或包括上述第六数量或第七数量的信息)时，根据该第四数量个PDSCH中的一个PDSCH时域资源确定该候选PDSCH接收时机。例如，该一个PDSCH可以是第四数量个PDSCH中的最后 一个PDSCH，但本申请并不以此作为限制，该第四数量大于1。
在一些实施例中，在第一时域资源分配表的一行(即一个第一信息元素)对应第四数量(D)个PDSCH时域资源(例如包括多个第二信息元素或包括上述第六数量或第七数量的信息)时，根据该第四数量个PDSCH中的至少两个(P个)PDSCH时域资源确定该候选PDSCH接收时机。例如，该至少两个(P个)PDSCH可以是第四数量个PDSCH，即P＝D，但本申请并不以此作为限制，该第四数量大于1。
以下具体说明上述两种实施例如何确定该候选PDSCH接收时机。
在一些实施例中，针对HARQ-ACK信息反馈时隙n u，根据与激活的上行部分带宽UL BWP关联的时隙定时值K 1集合，可以分别确定与K 1集合中各个K 1对应的下行时隙n D，其中K 1表示PDSCH相对于HARQ-ACK信息反馈时隙n u的偏移值，K 1集合的确定具体可以参考现有技术，在确定各个K 1对应的下行时隙时，可选的，还需要考虑上下行部分带宽的子载波间隔，一个K 1可能对应多个下行时隙，具体可参考现有技术，本申请实施例并不以此作为限制。
在一些实施例中，终端设备根据第二时域资源分配表确定第一数量个候选PDSCH接收时机。针对一个K 1对应的下行时隙，如果第二时域资源分配表所有行都满足第一条件，则该下行时隙没有对应的候选PDSCH接收时机，如果该第二时域资源分配表至少一行不满足第一条件，则该下行时隙有对应的候选PDSCH接收时机，或者，针对一个K 1对应的下行时隙，如果第二时域资源分配表所有行都不满足第二条件，则该下行时隙没有对应的候选PDSCH接收时机，如果该第二时域资源分配表至少一行满足第二条件，则该下行时隙有对应的候选PDSCH接收时机；例如，该第一条件可以是以下情况的至少之一：对应的一个或至少两个第五PDSCH时域资源包括半静态配置为上行的符号，对应的一个或至少两个第五PDSCH时域资源包括配置了PRACH的符号，对应的一个或至少两个第五PDSCH时域资源包括配置为无效的符号，不能用来调度该下行时隙对应的PDSCH；该第二条件可以是以下情况的至少之一：对应的一个或至少两个第五PDSCH时域资源不包括半静态配置为上行的符号，对应的一个或至少两个第五PDSCH时域资源不包括配置了PRACH的符号，对应的一个或至少两个第五PDSCH时域资源不包括配置为无效的符号，能用来调度该下行时隙对应的PDSCH。针对各个K 1对应的各个下行时隙，分别根据上述方式确定各下行时隙是否有对应的候选PDSCH接收时机，从而确定该第一数量个候选PDSCH接 收时机，其中，第二时域资源分配表R用于确定该第一数量个候选PDSCH接收时机，第二时域资源分配表R是根据第一时域资源分配表确定的，例如该第二时域资源分配表包括第一时域资源分配表的所有配置，或部分配置，后述将会详细举例说明。
例如，第二时域资源分配表包括第一时域资源分配表的所有配置，该第二时域资源分配表的一行对应第一时域资源表的一行(即一个第一信息元素)，该第一时域资源分配表的一行对应第四数量(D)个PDSCH时域资源(例如包括多个第二信息元素或包括上述第六数量或第七数量的信息)时，该第二时域资源分配表的一行也对应第四数量个PDSCH时域资源。
针对“根据该第四数量个PDSCH中的一个PDSCH时域资源确定该候选PDSCH接收时机”的情况：
将该第四数量个PDSCH时域资源中的一个PDSCH时域资源作为一个第五PDSCH时域资源，根据该一个第五PDSCH时域资源确定候选PDSCH接收时机，例如判断该第五PDSCH时域资源是否包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH，如果是则该第五PDSCH对应的行满足第一条件，如果不是，则该第五PDSCH对应的行满足第二条件，例如可以将第四数量个PDSCH时域资源中的最后一个PDSCH时域资源作为该一个第五PDSCH时域资源；
针对“根据该第四数量个PDSCH中的至少两个PDSCH时域资源确定该候选PDSCH接收时机”的情况：
将该第四数量个PDSCH时域资源中的至少两个(P个)PDSCH时域资源作为P个第五PDSCH时域资源，根据该P个第五PDSCH时域资源确定候选PDSCH接收时机，例如判断该P个第五PDSCH时域资源中任一个第五PDSCH是否包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH时域资源是否满足第一条件或第二条件，如果是，则该该P个第五PDSCH对应的行满足第一条件，如果不是，则该P个第五PDSCH对应的行满足第二条件。例如可以将第四数量个PDSCH时域资源都作为该P个第五PDSCH时域资源，但本实施例并不以此作为限制。
或者，例如，将该第四数量个PDSCH时域资源中的至少两个(P个)PDSCH时域资源作为P个第五PDSCH时域资源，根据该P个第五PDSCH时域资源确定候选 PDSCH接收时机，例如判断该P个第五PDSCH时域资源中每一个第五PDSCH是否包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH时域资源是否满足第一条件或第二条件，如果是，则该P个第五PDSCH对应的行满足第一条件，如果不是，则该P个第五PDSCH对应的行满足第二条件。例如可以将第四数量个PDSCH时域资源都作为该P个第五PDSCH时域资源，但本实施例并不以此作为限制。
例如，第二时域资源分配表包括第一时域资源分配表的部分配置，该第二时域资源分配表的一行对应第一时域资源表的一行(即一个第一信息元素)，该第一时域资源分配表的一行对应第四数量(D)个PDSCH时域资源(例如包括多个第二信息元素或包括上述第六数量或第七数量的信息)时，该第二时域资源分配表的一行对应一个PDSCH时域资源，该一个PDSCH时域资源是该第四数量个PDSCH时域资源中的一个PDSCH时域资源，例如可以将第四数量个PDSCH时域资源中的最后一个PDSCH时域资源作为该一个PDSCH时域资源。
针对“根据该第四数量个PDSCH中的一个PDSCH时域资源确定该候选PDSCH接收时机”的情况：
将该一个PDSCH时域资源作为一个第五PDSCH时域资源，根据该一个第五PDSCH时域资源确定候选PDSCH接收时机，例如判断该第五PDSCH时域资源是否包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH时域资源是否满足第一条件或第二条件，如果是，则该第五PDSCH对应的行满足第一条件，如果不是，则该第五PDSCH对应的行满足第二条件。
例如，第二时域资源分配表包括第一时域资源分配表的部分配置，该第二时域资源分配表的一行对应第一时域资源表的一行(即一个第一信息元素)，该第一时域资源分配表的一行对应第四数量(D)个PDSCH时域资源(例如包括多个第二信息元素或包括上述第六数量或第七数量的信息)时，该第二时域资源分配表的一行对应至少两个(P个)第五PDSCH时域资源。
针对“根据该第四数量个PDSCH中的至少两个PDSCH时域资源确定该候选PDSCH接收时机”的情况：
该至少两个(P个)第五PDSCH时域资源是该第四数量个PDSCH时域资源中 的P个PDSCH时域资源(P小于D)，根据该至少两个第五PDSCH时域资源确定候选PDSCH接收时机，例如判断该至少两个第五PDSCH时域资源的每一个是否包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH时域资源是否满足第一条件或第二条件，如果是，则该P个第五PDSCH对应的行满足第一条件，如果不是，则该P个第五PDSCH对应的行满足第二条件；或者判断该至少两个第五PDSCH至少一个是否包含包括半静态配置为上行的符号或包括配置了PRACH的符号或包括配置为无效的符号或不能用来调度该下行时隙对应的PDSCH时域资源是否满足第一条件或第二条件，如果是，则该P个第五PDSCH对应的行满足第一条件，如果不是，则该P个第五PDSCH对应的行满足第二条件。
在一些实施例中，在确定第一数量个候选PDSCH接收时机时，还可以考虑BWP切换时机，例如下行时隙在BWP切换之前而对应的上行时隙(即UE发送上述第一HARQ-ACK信息的上行时隙)在BWP切换之后，则该下行时隙没有对应的候选PDSCH接收时机，另外，确定第一数量个候选PDSCH接收时机还可以考虑其他因素，例如UE能力等，具体可以参考现有技术，此处不再一一赘述。
上述实施例说明如何确定该第一数量个候选PDSCH接收时机，在502中，确定与第一数量个候选PDSCH接收时机对应的HARQ-ACK信息比特，在一些实施例中，该候选PDSCH接收时机对应的HARQ-ACK信息比特数与该候选PDSCH接收时机对应的第二数量(B)和/或PDSCH之间的HARQ-ACK绑定关系相关，也就是说，终端设备可以根据该第二数量和该绑定关系确定一个候选PDSCH接收时机对应的HARQ-ACK信息比特数。
在一些实施例中，该第二数量可以是该候选PDSCH接收时机对应的第四PDSCH(候选PDSCH)的数量，换句话说，本申请实施例中的第四PDSCH(或也叫候选PDSCH)用于确定候选PDSCH接收时机对应的HARQ-ACK信息比特，例如是指可以(或可能/能够)由一个DCI调度的PDSCH数，但不相当于实际被DCI调度的PDSCH(第二PDSCH)数或实际被DCI指示的PDSCH(第一PDSCH)数。一个候选PDSCH接收时机对应的HARQ-ACK信息比特数与该候选PDSCH接收时机对应的第二数量B相关是指该第二数量的值会影响该候选PDSCH接收时机对应的HARQ-ACK信息比特数的值。例如，假设一个候选PDSCH接收时机对应的HARQ-ACK信息比特数
Figure PCTCN2020121335-appb-000005
其中，
Figure PCTCN2020121335-appb-000006
表示一个PDSCH对应的HARQ-ACK信息比特数，而一个候选PDSCH接收时机对应的HARQ-ACK信息比特数与该第二数量B相关是指
Figure PCTCN2020121335-appb-000007
等于第二数量。
例如，该第二数量是第二时域资源分配表或第一时域资源分配表中各行对应的PDSCH的数量中的最大数。其中，在第一信息元素包括至少两个第二信息元素时，例如，第一时域资源分配表或第二时域资源分配表的一行对应至少两个PDSCH时域资源时，该第二数量是各行对应的PDSCH时域资源数量的最大数；在第一信息元素包括第六数量或第七数量的信息时，例如，第一时域资源分配表或第二时域资源分配表的一行对应配置了第六数量(或第七数量)的信息时，该第二数量是各行对应的第六数量(或第七数量)中的最大数。其中，各候选PDSCH接收时机对应的HARQ-ACK信息比特数相同。
或者，例如，该第二数量是第二时域资源分配表中满足第二条件的各行对应的PDSCH的数量中的最大数。其中，在第一信息元素包括至少两个第二信息元素时，例如，第一时域资源分配表或第二时域资源分配表的一行对应至少两个PDSCH时域资源时，该第二数量是满足第二条件的各行对应的PDSCH时域资源数量的最大数；在第一信息元素包括第六数量或第七数量的信息时，例如，第一时域资源分配表或第二时域资源分配表的一行对应配置了第六数量(或第七数量)的信息时，该第二数量是满足第二条件的各行对应的第六数量(或第七数量)中的最大数。其中，各候选PDSCH接收时机对应的HARQ-ACK信息比特数相同或不同。一行是否满足第二条件的实施方法如前所述，此处不再赘述。
或者，例如，该第二数量是第二时域资源分配表中满足第二条件的的各行对应的除包含被半静态配置为上行符号或包含配置了PRACH的符号或包括配置为无效的符号的PDSCH的数量中的最大数。其中，在第一信息元素包括至少两个第二信息元素时，例如，第一时域资源分配表或第二时域资源分配表的一行对应至少两个PDSCH时域资源时，该第二数量是满足第二条件的PDSCH的各行对应的除包含被半静态配置为上行符号或包含配置了PRACH的符号或包括配置为无效的符号的PDSCH的时域资源数量的最大数；在第一信息元素包括第六数量或第七数量的信息时，例如，第一时域资源分配表或第二时域资源分配表的一行对应配置了第六数量(或第七数量) 的信息时，该第二数量是满足第二条件的PDSCH的各行对应的第八数量中的最大数，该第八数量是第六数量(或第七数量)减去包含被半静态配置为上行符号或包含配置了PRACH的符号或包括配置为无效的符号的PDSCH数量。其中，各候选PDSCH接收时机对应的HARQ-ACK信息比特数相同或不同。一行是否满足第二条件的判断实施方法如前所述，此处不再赘述。
在一些实施例中，一个候选PDSCH接收时机对应的HARQ-ACK信息比特数与PDSCH之间的HARQ-ACK绑定关系相关是指在候选PDSCH接收时机对应的第四PDSCH(候选PDSCH)中至少两个第四PDSCH之间具有HARQ-ACK绑定关系时，对具有绑定关系的至少两个第四PDSCH的HARQ-ACK信息比特进行联合编码。该联合编码可以是针对具有HARQ-ACK绑定关系的PDSCH对应的HARQ-ACK信息比特进行逻辑与运算。
在上述实施例中，在具有上述绑定关系时，由于进行了联合编码，该一个候选PDSCH接收时机对应的HARQ-ACK信息比特数会减少。
在一些实施例中，该方法还可以包括(可选，未图示)，该终端设备接收用于配置PDSCH之间的HARQ-ACK绑定关系的配置信息，该配置信息harq-ACK-PDSCHBundlingPUCCH可以由RRC信令承载。例如，在配置信息配置了可以由一个DCI调度的多个PDSCH(一个候选PDSCH接收时机对应的各个第四PDSCH)之间具有HARQ-ACK绑定关系时，该一个候选PDSCH接收时机对应的HARQ-ACK信息比特数等于一个PDSCH对应的HARQ-ACK信息比特数
Figure PCTCN2020121335-appb-000008
例如下表1所示，一个候选PDSCH接收时机对应的两个第四PDSCH(即PDSCH1和PDSCH2)之间具有HARQ-ACK绑定关系，则该一个候选PDSCH接收时机对应的HARQ-ACK信息为联合编码后的信息。

在一些实施例中，一个PDSCH对应的HARQ-ACK信息比特数
Figure PCTCN2020121335-appb-000009
可以根据空间绑定参数，码块组(CBG)配置参数，支持的最大码字参数确定，例如可以 是1比特或2比特，具体可以参考现有技术，此处不再赘述。
在一些实施例中，该第一数量个(A个)候选PDSCH接收时机中的至少两个候选PDSCH接收时机分别对应的第二数量相同或不同，本实施例并不以此作为限制。
在一些实施例中，上述说明了如何确定一个候选PDSCH接收时机对应的HARQ-ACK信息比特数，第一数量个(A个)候选PDSCH接收时机中各个候选PDSCH接收时机对应的HARQ-ACK信息比特数的确定方式类似(其中，第二数量的确定方式可能不同)，此处不再一一赘述。
在现有技术中，一个PDSCH的HARQ-ACK信息对应该码本的一个候选PDSCH接收时机，因此，该候选PDSCH接收时机对应的HARQ-ACK信息就是该一个PDSCH的HARQ-ACK信息，在本申请实施例中，由于一个候选PDSCH接收时机可以对应多个第四PDSCH，例如至少一个(N个)第二PDSCH的第二HARQ-ACK信息可以对应同一个候选PDSCH接收时机，因此，在确定了一个候选PDSCH接收时机对应的HARQ-ACK信息比特数后，还需要确定该候选PDSCH接收时机对应的HARQ-ACK信息比特如何排列。并使用相同的方式依次确定第一数量个(A个)中各个候选PDSCH接收时机对应的HARQ-ACK信息比特，按照候选PDSCH接收时机对应的时域顺序或者按照各候选PDSCH接收时机的索引排列第一数量个(A个)中各个候选PDSCH接收时机对应的HARQ-ACK信息比特，以得到一个服务小区的HARQ-ACK信息比特，可以将一个服务小区的HARQ-ACK信息比特作为码本进行反馈。
在一些实施例中，该候选PDSCH接收时机对应的HARQ-ACK信息比特可以按该候选PDSCH接收时机对应的第四PDSCH的顺序排列，也就是说，按该候选PDSCH接收时机对应的第四PDSCH的时域顺序或索引排列；例如，从候选PDSCH接收时机对应的HARQ-ACK信息比特的低位(LSB)开始，按照第四PDSCH的顺序依次排列各个第四PDSCH对应的HARQ-ACK信息比特，将该候选PDSCH接收时机对应的剩余HARQ信息比特设为NACK，其中，针对没有对应第二PDSCH的第四PDSCH(即没有对应的实际调度的PDSCH的候选PDSCH)，其对应的HARQ-ACK信息比特设为NACK。图6A和图6B是该候选PDSCH接收时机信息比特排列示意图，如图6A所示，候选PDSCH接收时机0，1，2，每个候选PDSCH接收时机对应两个第四PDSCH(即可以由一个DCI调度的PDSCH数)相同，且为2，其中候选 PDSCH接收时机0的两个第四PDSCH上都有对应的第二PDSCH(i.e.PDSCH1和PDSCH2)，候选PDSCH接收时机1的两个第四PDSCH上没有对应的第二PDSCH，候选PDSCH接收时机2上的两个PDSCH上有一个对应的第一PDSCH(i.e.PDSCH3)和一个对应的第二PDSCH(i.e.PDSCH4)，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，则该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,NACK,PDSCH4-HARQ},其中，PDSCH1-HARQ表示PDSCH1对应的HARQ-ACK信息(NACK或ACK)，以此类推；如图6B所示，候选PDSCH接收时机0，1，2，每个候选PDSCH接收时机对应两个第四PDSCH(即可以由一个DCI调度的PDSCH数)相同，且为2，其中候选PDSCH接收时机0的两个第四PDSCH上都有对应的第二PDSCH(i.e.PDSCH1和PDSCH2)，候选PDSCH接收时机1的两个第四PDSCH上没有对应的第二PDSCH，候选PDSCH接收时机2上的两个PDSCH上有一个对应的第二PDSCH(i.e.PDSCH3)，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，则该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,NACK,PDSCH3-HARQ}，其中，该1比特的值为0时，表示NACK，该1比特的值为1时，表示ACK。
在一些实施例中，该候选PDSCH接收时机对应的HARQ-ACK信息比特可以按该候选PDSCH接收时机对应的第二PDSCH的顺序依次排列，也就是说，按该候选PDSCH接收时机对应的第二PDSCH的时域顺序或索引排列；例如，从候选PDSCH接收时机对应的HARQ-ACK信息比特的低位(LSB)开始，按照第二PDSCH的顺序依次排列各个第二PDSCH对应的HARQ-ACK信息比特，将该候选PDSCH接收时机对应的剩余HARQ信息比特设为NACK，例如针对图6A所示，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，则该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,NACK,PDSCH4-HARQ}；如图6B所示，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,PDSCH3-HARQ,NACK}，其中，该1比特的值为0时，表示NACK，该1比特的值为1时，表示ACK。
在一些实施例中，该候选PDSCH接收时机对应的HARQ-ACK信息比特可以按该候选PDSCH接收时机对应的第一PDSCH的顺序依次排列，按该候选PDSCH接收时机对应的第一PDSCH的时域顺序或索引排列。例如，从候选PDSCH接收时机对 应的HARQ-ACK信息比特的低位(LSB)开始，按照第一PDSCH的顺序依次排列各个第一PDSCH对应的HARQ-ACK信息比特，将该候选PDSCH接收时机对应的剩余HARQ信息比特设为NACK，其中，针对不是第二PDSCH的第一PDSCH，其对应的HARQ-ACK信息比特设为NACK，例如针对图6A所示，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，则该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,NACK,PDSCH4-HARQ}；如图6B所示，假设一个第四PDSCH对应的HARQ-ACK信息为1比特，该码本为{PDSCH1-HARQ,PDSCH2-HARQ,NACK,NACK,PDSCH3-HARQ,NACK}，其中，该1比特的值为0时，表示NACK，该1比特的值为1时，表示ACK。
在一些实施例中，如前所述，在码本包括一个服务小区的HARQ-ACK信息比特的情况下，将该一个服务小区的HARQ-ACK信息比特作为码本进行反馈，在码本包括多个服务小区的HARQ-ACK信息比特的情况下，各个服务小区的HARQ-ACK信息比特的确定方式与前述一个服务小区的HARQ-ACK信息比特的确定方式相同，但在具体确定时，各服务小区对应的第一时域资源分配表和/或第二时域资源分配表，K1集合等其他参数可能是相同的或者不同的，例如上述参数可能是针对各服务小区单独配置的，但本实施例并不以此作为限制。各个服务小区对应的HARQ-ACK信息比特可以按照服务小区的索引升序依次排列，以生成码本进行反馈。
II.至少一个(N个)第二PDSCH的第二HARQ-ACK信息可以对应不同的候选PDSCH接收时机(即N个第二PDSCH的第二HARQ-ACK信息在不同的候选PDSCH接收时机对应的HARQ-ACK信息比特反馈)
在一些实施例中，采用与前述I中相同的方式确定与K 1集合中各个K 1对应的下行时隙，并确定各下行时隙是否有对应的候选PDSCH接收时机，例如根据上述第四数量个PDSCH中的一个或至少两个第五PDSCH来确定候选PDSCH接收时机，具体实施方式如前所述，此处不再赘述。
与前述I中的不同之处在于，一个候选PDSCH接收时机对应一个第四PDSCH，而不是多个第四PDSCH，为了支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息，针对上述有对应候选PDSCH接收时机的各下行时隙，一个下行时隙对应的候选PDSCH接收时机数为第三数量。有对应候选PDSCH接收时机的下行时隙中的至少一个下行时隙对应的第三数量个候选PDSCH接收时机中的至少两个候选PDSCH 接收时机对应不同的时隙(或者说，在不同的时隙)。
在一些实施例中，该第三数量大于1，和/或该第三数量与该下行时间单元对应的第九数量(I)和/或PDSCH之间的HARQ-ACK绑定关系相关，其中第九数量I的确定方式可以参考第二数量B的确定方式，该绑定关系的配置方式如I中所述，此处不再赘述。该第三数量大于1是指，有对应候选PDSCH接收时机的下行时隙中的至少一个下行时隙对应多于1个候选PDSCH接收时机。
在一些实施例中，第三数量与第九数量有关是指第三数量大于或等于第九数量，例如，根据UE能力确定该第三数量是等于第九数量还是大于第九数量，当UE不支持在一个下行时隙中接收多于一个PDSCH时，该第三数量等于该第九数量，当UE不支持在一个下行时隙中接收多于一个PDSCH时，该第三数量大于该第九数量。
在一些实施例中，第三数量与PDSCH之间的HARQ-ACK绑定关系相关是指在对应一个下行时隙的候选PDSCH接收时机对应的第四PDSCH之间具有HARQ-ACK绑定关系时，该第三数量可以减少，例如该第三数量可以小于该第九数量。例如，当UE不支持在一个下行时隙中接收多于一个PDSCH时，在RRC信令配置了具有绑定关系的情况下，第三数量等于1，当UE不支持在一个下行时隙中接收多于一个PDSCH时，在RRC信令配置了具有绑定关系的情况下，该第三数量等于该第二时域资源分配表中在对应的时域资源(例如对应的第五PDSCH的时域资源)上没有重叠的行的数量。
在一些实施例中，由于一个候选PDSCH接收时机对应一个PDSCH，因此，按第一数量个候选PDSCH接收时机的顺序排列各候选PDSCH接收时机对应的HARQ-ACK信息比特，以得到一个服务小区的HARQ-ACK信息比特。其中，如果一个候选PDSCH接收时机没有对应的第二PDSCH，其对应的HARQ-ACK信息比特设为NACK。如前所述，在码本包括一个服务小区的HARQ-ACK信息比特的情况下，将该一个服务小区的HARQ-ACK信息比特作为码本进行反馈，在码本包括多个服务小区的HARQ-ACK信息比特的情况下，各个服务小区的HARQ-ACK信息比特的确定方式与前述一个服务小区的HARQ-ACK信息比特的确定方式相同，但在具体确定时，各服务小区对应的第一时域资源分配表和/或第二时域资源分配表，K1集合等其他参数可能是相同的或者不同的，例如上述参数可能是针对各服务小区单独配置的，但本实施例并不以此作为限制。各个服务小区对应的HARQ-ACK信息比特可以按照 服务小区的索引升序依次排列，以生成码本进行反馈。
值得注意的是，以上附图2,5仅对本申请实施例进行了示意性说明，但本申请不限于此。例如可以适当地调整各个操作之间的执行顺序，此外还可以增加其它的一些操作或者减少其中的某些操作。本领域的技术人员可以根据上述内容进行适当地变型，而不仅限于上述附图2,5的记载。
以上各个实施例仅对本申请实施例进行了示例性说明，但本申请不限于此，还可以在以上各个实施例的基础上进行适当的变型。例如，可以单独使用上述各个实施例，也可以将以上各个实施例中的一种或多种结合起来。
由上述实施例可知，通过一个DCI可以调度多个PDSCH，并通过一种新的HARQ-ACK信息反馈方法支持反馈一个DCI调度的多个PDSCH的HARQ-ACK信息，由此减轻终端设备的DCI监听负担，降低耗电量以及复杂度。
第二方面的实施例
本申请实施例提供一种信息接收方法，从网络设备侧说明，其中，与第一方面的实施例的重复部分不再赘述。
图7是本申请实施例的信息接收方法的一示意图，如图7所示，该方法包括：
