反馈信息传输方法及通信装置
本申请要求于2019年8月16日提交中国专利局、申请号为201910760949.4、申请名称为“反馈信息传输方法及通信装置”的中国专利申请的优先权，以及本申请要求于2019年9月29日提交中国专利局、申请号为201910936461.2、申请名称为“反馈信息传输方法及通信装置”的中国专利申请的优先权。上述两个中国专利申请的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，尤其涉及一种反馈信息传输方法及通信装置。
背景技术
在数据传输过程中，为了保证数据传输的可靠性，终端需要对基站发送的数据，反馈混合自动重传请求(Hybrid Automatic Repeat request,HARQ)-确认信息(ACK)，以使得基站确认是否需要重传该数据。
在多站协作传输场景中，终端可以接收到多个传输点(transmission and reception point，TRP)调度的下行数据，终端解调这些下行数据后，还需要发送这些下行数据的HARQ-ACK信息，从而使得各TRP获知数据的传输情况。然而，该种情况下，终端这些下行数据的HARQ-ACK信息是联合发送给一个或多个TRP，还是分别发送给对应的TRP成为一个亟待解决的问题。
发明内容
本申请提供一种反馈信息传输方法及通信装置，能够确定多个反馈信息之间的反馈方式。
第一方面，本申请提供一种反馈信息传输方法。该反馈信息传输方法中，在多个反馈信息分别对应的资源指示信息相同时，基于该多个反馈信息生成联合反馈信息；在多个反馈信息分别对应的资源指示信息不同时，分别反馈多个反馈信息中的至少一个。
针对第一反馈信息和第二反馈信息，终端确定第一反馈信息对应的第一下行控制信息(downlink control information,DCI)，以及第二反馈信息对应的第二DCI。其中，第一反馈信息与第二反馈信息分别关联的下行控制相关参数不同。也就是说，第一反馈信息和第二反馈信息是不同网络设备所调度的下行数据的反馈信息。其中，第一DCI包括第一资源指示信息，第一资源指示信息用于确定所述第一反馈信息所占的时频资源。第二DCI包括第二资源指示信息，第二资源指示信息用于确定所述第二反馈信息所占的时频资源。
第一资源指示信息与第二资源指示信息相同时，终端基于所述第一反馈信息和所述第二反馈信息生成联合反馈信息。第一资源指示信息与第二资源指示信息不相同时，终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。
可见，终端在不需要接收额外的信令指示，就能够确定多个反馈信息之间的反馈方式，节省了信令开销。
本申请中，第一反馈信息对应的第一DCI，为该第一反馈信息对应的一个或多个DCI中的最后一个DCI。第二反馈信息对应的第二DCI，为该第二反馈信息对应的一个或多个DCI中的最后一个DCI。
最后一个DCI是指反馈信息对应的一个或多个下行控制信道中，最靠后的PDCCH检测时机检测的PDCCH所承载的DCI。当终端被配置了多个服务小区时，先将每个PDCCH检测时机按照从小到大(即从先到后)排序后，再把每个PDCCH检测时机检测的PDCCH按照服务小区标识从小到大排序。最后一个DCI为排序后排列在最后一个的PDCCH承载的DCI。
在一种实施方式中，终端判断上述资源指示信息是否相同之前，还可确定第一时间单元指示信息指示的时间单元与第二时间单元指示信息指示的时间单元相同。第一时间单元指示信息，用于指示第一反馈信息所占时频资源所在的时间单元。第二时间单元指示信息，用于指示第二反馈信息所占时频资源所在的时间单元。
反馈信息所占时频资源所在的时间单元可以是基于高层信令配置的一时序偏移值确定的。或者，反馈信息所占时频资源所在的时间单元是基于高层信令配置的多个时序偏移值以及反馈信息对应的DCI中时序偏移指示域-码点的值确定。

在一种实施方式中，终端还可以判断所述第一反馈信息的比特数与所述第二反馈信息的比特数是否分别对应同一个上行控制信道资源集合。若分别对应同一个上行控制信道资源集合，则执行上述的其他判断。若分别对应不同的上行控制信道资源集合，则终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。
在一种实施方式中，终端还可以判断第一控制信道元素CCE位置与第二CCE位置是否相同；所述第一CCE位置，为承载所述第一DCI的下行控制信道所占据的控制信道元素CCE的位置；所述第二CCE位置，为承载所述第二DCI的下行控制信道所占据的控制信道元素CCE的位置。若第一控制信道元素CCE位置与第二CCE位置相同，则终端可以执行其他上述判断；若不同，则终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。可见，该实施方式有利于在基于反馈信息的比特数确定的上行控制信道资源集合中包括较多的上行控制信道资源时，可结合CCE位置确定一上行控制信道资源，作为该反馈信息所占的时频资源。
上述各实施方式中，终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个，包括：第一资源指示信息指示的时频资源与所述第二资源指示信息指示的时频资源在时域上存在重叠时，所述终端反馈所述第一反馈信息，不反馈所述第二反馈信息。所述第一资源指示信息指示的时频资源与所述第二资源指示信息指示的时频资源在时域上不存在重叠时，所述终端分别反馈所述第一反馈信息，以及所述第二反馈信息。

另一种实施方式中，所述第一反馈信息关联的控制资源集合中高层参数的索引号大于所述第二反馈信息关联的控制资源集合中高层参数的索引号；或者所述第一反馈信息关联的控制资源集合中高层参数的索引号小于所述第二反馈信息关联的控制资源集合中高层参数的索引号；或者所述第一反馈信息关联的控制资源集合中高层参数的索引号为预设索引号。故第一资源指示信息指示的时频资源与所述第二资源指示信息指示的时频资源在时域上存在重叠时，所述终端反馈所述第一反馈信息，不反馈所述第二反馈信息。

根据所述DCI中的资源指示信息、控制信道元素CCE位置确定上行控制信道资源时，依赖于资源指示信息所占的比特数、控制信道元素CCE位置的多少，比如，资源指示信息所占的比特数为3个、控制信道元素CCE位置的有8个时，终端最多可被分配24个上行控制信道资源，当上行控制信道资源大于24个时，将无法被完全指示。因此，该实施方式通过引入CORESET具有的高层参数确定上行控制信道资源，可大大增加终端设备可被配置的上行控制信道资源个数，即可被配置大于24个的上行控制信道资源，例如64个上行控制信道资源。
在一种实施方式中，所述终端设备根据所述DCI中的资源指示信息、CCE位置和高层参数，确定上行控制信道资源，包括：终端设备根据该DCI中的资源指示信息和CCE位置确定第一资源编号；终端设备根据该第一资源编号和高层参数的索引号，确定第二资源编号；终端设备从上行控制信道资源集合中确定该第二资源编号对应的上行控制信道资源。
该实施方式中，终端设备根据该DCI中的资源指示信息和CCE位置确定第一资源编号r PUCCH，可采用以下公式确定，以上行控制信道资源为PUCCH资源为例：

其中，mod表示求余；N CCE,p是该DCI所在的CORESET中的CCE的总个数，是由高层信令配置的；
n CCE,p是承载该DCI的PDCCH所占据的CCE位置；
Δ PRI是该DCI中的资源指示信息(PUCCH resource indicator field,PRI)；

可见，该实施方式中，终端设备能够被配置的上行控制信道资源集合中上行控制信道资源的个数依赖与终端设备被配置的控制资源集合组的个数。当终端设备被配置多个控制资源集合组时，终端设备可被配置上行控制信道资源集合，该上行控制信道资源集合具有超过32个上行控制信道资源。每个控制资源集合组可被分配不超过32个上行控制信道资源，从而可利用该实施方式确定上行控制信道资源。
在另一种实施方式中，终端设备根据所述DCI中的资源指示信息、CCE位置和高层参数，确定上行控制信道资源，包括：终端设备根据被配置的多个控制资源集合组中多个高层参数和所述DCI的PDCCH的配置信息，确定被配置的上行控制信道资源的个数；终端设备根据所述DCI中的资源指示信息和CCE位置，确定上行控制信道资源。
其中，终端设备根据所述DCI中的资源指示信息和CCE位置，确定上行控制信道资源，可采用上述实施方式所述的公式，其中，R PUCCH为确定的被配置的上行控制信道资源的个数。
在又一种实施方式中，终端设备根据所述DCI中的资源指示信息、CCE位置和高层参数，确定上行控制信道资源，包括：终端设备根据所述DCI中的资源指示信息确定第一偏移；终端设备根据CCE位置和高层参数，确定第二偏移；终端设备根据第一偏移和第二偏移确定上行控制信道资源。

在具体实现过程中，处理器可用于进行，例如但不限于，基带相关处理，收发器可用于进行，例如但不限于，射频收发。上述器件可以分别设置在彼此独立的芯片上，也可以至少部分的或者全部的设置在同一块芯片上。例如，处理器可以进一步划分为模拟基带处理器和数字基带处理器。其中，模拟基带处理器可以与收发器集成在同一块芯片上，数字基带处理器可以设置在独立的芯片上。随着集成电路技术的不断发展，可以在同一块芯片上集成的器件越来越多，例如，数字基带处理器可以与多种应用处理器(例如但不限于图形处理器，多媒体处理器等)集成在同一块芯片之上。这样的芯片可以称为系统芯片(system on chip)。将各个器件独立设置在不同的芯片上，还是整合设置在一个或者多个芯片上，往往取决于产品设计的具体需要。本发明实施例对上述器件的具体实现形式不做限定。
第十六方面，本申请还提供一种处理器，用于执行上述各种方法。在执行这些方法的过程中，上述方法中有关发送上述信息和接收上述信息的过程，可以理解为由处理器输出上述信息的过程，以及处理器接收输入的上述信息过程。具体来说，在输出上述信息时，处理器将该上述信息输出给收发器，以便由收发器进行发射。更进一步的，该上述信息在由处理器输出之后，还可能需要进行其他的处理，然后才到达收发器。类似的，处理器接收输入的上述信息时，收发器接收该上述信息，并将其输入处理器。更进一步的，在收发器收到该上述信息之后，该上述信息可能需要进行其他的处理，然后才输入处理器。
基于上述原理，举例来说，前述方法中提及的接收下行控制信息可以理解为处理器输入下行控制信息。
如此一来，对于处理器所涉及的发射、发送和接收等操作，如果没有特殊说明，或者，如果未与其在相关描述中的实际作用或者内在逻辑相抵触，则均可以更加一般性的理解为处理器输出和接收、输入等操作，而不是直接由射频电路和天线所进行的发射、发送和接收操作。
在具体实现过程中，上述处理器可以是专门用于执行这些方法的处理器，也可以是执行存储器中的计算机指令来执行这些方法的处理器，例如通用处理器。上述存储器可以为非瞬时性(non-transitory)存储器，例如只读存储器(read only memory，ROM)，其可以与处理器集成在同一块芯片上，也可以分别设置在不同的芯片上，本发明实施例对存储器的类型以及存储器与处理器的设置方式不做限定。

具体实施方式
下面将结合附图，对本申请中的技术方案进行描述。
本申请的技术方案可具体应用于各种通信系统中。例如，随着通信技术的不断发展，本申请的技术方案还可用于未来网络，如5G系统，也可以称为新空口(new radio，NR)系统，或者可用于设备到设备(device to device，D2D)系统，机器到机器(machine to machine，M2M)系统等等。
本申请可以应用到车辆与网络(vehicle to network，V2N)之间的通信等车联网中。也就是说，本申请所述的终端也可以为车辆或应用于车辆中的车辆组件。图1是本申请实施 例提供的一种V2N系统的示意图。如图1所示，路边基础设施可以包括网络设备类型的路侧单元(road side unit，RSU)。该网络设备类型的RSU可以给与网络设备通信的车辆或车辆组件提供定时同步及资源调度。
其中，本申请实施例描述的网络架构以及业务场景是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
本申请中网络设备可为具有无线收发功能的设备或可设置于该设备的芯片，该网络设备包括但不限于：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 node B，或home Node B，HNB)、基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission and reception point，TRP或者transmission point，TP)等，还可以为5G，如，NR，系统中的gNB，或，传输点(TRP或TP)，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如BBU，或，分布式单元(DU，distributed unit)等，前述的V2X车联网中网络设备或网络设备类型的RSU。
在一些部署中，gNB或传输点可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括射频单元(radio unit，RU)。CU实现gNB或传输点的部分功能，DU实现gNB或传输点的部分功能，比如，CU实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能，DU实现无线链路控制(radio link control，RLC)、媒体接入控制(media access control，MAC)和物理(physical，PHY)层的功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令或PHCP层信令，也可以认为是由DU发送的，或者，由DU+RU发送的。可以理解的是，网络设备可以为CU节点、或DU节点、或包括CU节点和DU节点的设备。此外，CU可以划分为接入网RAN中的网络设备，也可以将CU划分为核心网CN中的网络设备，在此不做限制。
本申请中，终端也可以称为用户设备(user equipment，UE)、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、无线通信设备、用户代理或用户装置。本申请的实施例中的终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)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、前述的V2X车联网中的无线终端或无线终端类型的RSU等等。本申请的实施例对应用场景不做限定。本申请中，终端设备，可简称终端。
另外，在本申请实施例中，“示例的”一词用于表示作例子、例证或说明。本申请中被 描述为“示例”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言，使用示例的一词旨在以具体方式呈现概念。
本申请实施例中，“的(of)”，“相应的(relevant)”，“关联的”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。本申请实施例中，至少一个还可以描述为一个或多个，多个可以是两个、三个、四个或者更多个，本申请不做限制。在本申请实施例中，对于一种技术特征，通过“第一”、“第二”、“第三”、“A”、“B”、“C”和“D”等区分该种技术特征中的技术特征，该“第一”、“第二”、“第三”、“A”、“B”、“C”和“D”描述的技术特征间无先后顺序或者大小顺序。
本申请实施例中，反馈信息可以为混合自动重传请求(hybrid automatic repeat request,HARQ)-确认(ACK)码本。HARQ-ACK码本中包括一个或多个HARQ-ACK信息比特。一个HARQ-ACK信息比特为一个或多个下行数据的HARQ-ACK信息比特。该一个或多个下行数据是由同一个网络设备通过一个或多个物理下行控制信道(physical downlink control channel，PDCCH)所调度的一个或多个物理下行共享信道(physical downlink shared channel，PDSCH)分别承载的数据。该PDCCH承载的下行控制信息(downlink control information,DCI)用于告知终端如何接收PDSCH。该HARQ-ACK信息比特用于对接收的下行数据，如PDSCH承载的数据，进行肯定(ACK)或否定(NACK)的反馈，以便于丢失或出错的数据能进行重传。本文中，下行控制信道可以为物理下行控制信道。
HARQ-ACK码本所占的时频资源是基于该HARQ-ACK码本对应的DCI中的资源指示信息确定的，即该HARQ-ACK码本对应的DCI中资源指示信息用于确定该HARQ-ACK码本所占的时频资源。
HARQ-ACK码本对应的DCI是HARQ-ACK码本关联的一个或多个PDCCH中PDCCH检测时机最靠后的PDCCH所承载的DCI，或PDCCH接收时间最靠后的PDCCH承载的DCI。本文中，下行控制信道检测时机可以为物理下行控制信道检测时机，即PDCCH检测时机。
最后一个DCI是指反馈信息对应的一个或多个下行控制信道中，最靠后的PDCCH检测时机检测的PDCCH所承载的DCI。当终端被配置了多个服务小区时，先将每个PDCCH检测时机按照从小到大(即从先到后)排序后，再把每个PDCCH检测时机检测的PDCCH按照服务小区标识从小到大排序。最后一个DCI为排序后排列在最后一个的PDCCH承载的DCI。可选的，该HARQ-ACK码本对应的DCI也可称为该HARQ-ACK码本的最后一个DCI。
HARQ-ACK码本关联的一个或多个PDCCH，是该HARQ-ACK码本中各HARQ-ACK信息比特分别对应的PDCCH。一个HARQ-ACK信息比特对应的PDCCH是指该HARQ-ACK信息对应的下行数据被该PDCCH调度。
其中，PDCCH检测时机是根据下行控制相关参数配置所得到的。比如，下行控制相关参数配置包括搜索空间组信息(search space set，SS set)，其中，包括了SS set的周期、图样(pattern)等。由此，终端可以知道各个PDCCH检测时机的起始位置，例如起始符号。而SS set的配置中又关联CORESET标识，CORESET配置信息中包括CORESET所占的时域符号个数，如1、2、3个符号。所以，终端通过SS set配置可以知道PDCCH检测时机在 哪里，即在哪些符号上。因此，PDCCH的PDCCH检测时机为能够检测到该PDCCH的PDCCH检测时机。
PDCCH接收时间是终端接收到PDCCH的时间，是基于PDCCH检测时机进行检测时，实际接收到PDCCH的时间。
一个HARQ-ACK码本中各HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元相同。一种实施方式中，高层信令配置一个时序偏移值时，该时间单元指示信息就为该时序偏移值。另一种实施方式中，高层信令配置多个时序偏移值时，该时间单元指示信息还包括HARQ-ACK信息比特对应的DCI中时序偏移指示域-码点的值。该时序偏移指示域-码点的值用于指示高层信令配置的多个时序偏移值中的一个。时序偏移值的定义是传输PDSCH所在的时间单元到反馈HARQ-ACK信息比特的时间单元之间的时序偏移。另外，一个HARQ-ACK码本中各HARQ-ACK信息比特对应的各DCI分别关联的下行控制相关参数也相同。其中，时序偏移值也可以为时域指示值、或反馈时序指示等。DCI中的时序偏移指示域-码点可以为反馈时序指示域、或时间单元指示域。
又一种实施方式中，该时间单元指示信息可包括HARQ-ACK信息比特对应的DCI中的时序偏移指示域-码点的值。即终端可基于该DCI中的时序偏移指示域-码点的值，即可确定HARQ-ACK信息比特反馈所在的时间单元。
时间单元可以是一个或多个无线帧，一个或多个子帧，一个或多个时隙，一个或多个微时隙(mini slot)，一个或多个符号，也可以是多个帧或子帧构成的时间窗口，例如系统信息(system information，SI)窗口。本申请实施例对一个符号的时间长度不做限制。针对不同的子载波间隔，一个符号的长度可以有所不同。符号可以包括上行符号和下行符号，其中，上行符号可以称为单载波频分多址(single carrier-frequency division multiple Access，SC-FDMA)符号或正交频分多址(orthogonal frequency division multiplexing，OFDM)符号；下行符号可以称为OFDM符号。
其中，DCI中该时序偏移指示域-码点(code point)的值与高层参数配置的多个时序偏移值有一一对应的关系。例如，该时序偏移指示域-码点的取值从小到大与高层信令配置的K1集合set{k0,k1,…,ki}(比如，ki表示高层信令配置的多个时序偏移值的索引号)从先到后的顺序一一对应。比如，该时序偏移指示域-码点的取值00、01、10、11分别与高层信令配置的k0、k1、k2、k3值对应。若该时序偏移指示域-码点的值为00，则该DCI调度的PDSCH的HARQ-ACK信息比特对应的时间单元就基于该k0值标识的时序偏移值确定。
例如，高层信令指示一个时序偏移值K1，该K1等于2，以及时间单元以时隙slot，以及上下行子载波间隔相同为例。如图2所示，TRP1通过PDCCH0承载的DCI0，调度slot n传输PDSCH0；以及通过PDCCH1承载的DCI1，调度slot n+1传输PDSCH1。那么，PDSCH0的HARQ-ACK信息比特对应的时间单元指示信息为该K1＝2，该时间单元指示信息指示的时间单元为：PDSCH0所占时频资源所在的时间单元向后数第2个时间单元，即slot n+2。PDSCH1的HARQ-ACK信息比特对应的时间单元指示信息为该K1＝2，该时间单元指示信息指示的时间单元为：PDSCH1所占时频资源所在的时间单元向后数第2个时间单元，即slot n+1+2，即slot n+3。
以高层信令指示多个时序偏移值K1set＝{k0＝4,k1＝3}，以及时间单元以时隙slot，以及 上下行子载波间隔相同为例。如图3所示，TRP1通过PDCCH0承载的DCI0，调度slot n传输PDSCH0；以及通过PDCCH1承载的DCI1，调度slot n+1传输PDSCH1。DCI0中时序偏移指示域-码点的值等于4或k0；DCI1中时序偏移指示域-码点的值等于3或k1。那么，PDSCH0的HARQ-ACK信息比特对应的时间单元指示信息包括高层信令配置的K1set＝{k0＝4,k1＝3}以及DCI0中时序偏移指示域-码点的值。PDSCH1的HARQ-ACK信息比特对应的时间单元指示信息包括高层信令配置的K1set＝{k0＝4,k1＝3}以及DCI1中时序偏移指示域-码点的值。PDSCH0的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元为：PDSCH0所占时频资源所在的时间单元slot0向后数第4个时间单元，即slot n+4。PDSCH1的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元为：PDSCH1所占时频资源所在的时间单元slot n+1向后数第3个时间单元，即slot1n+1+3，即slot n+4。
图2中，PDSCH0的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元slot2，PDSCH1的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元为slot3，因此，终端不能将PDSCH0的HARQ-ACK信息比特和PDSCH1的HARQ-ACK信息比特放在一个HARQ-ACK码本中反馈。
图3中，PDSCH0的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元为slot4，PDSCH1的HARQ-ACK信息比特对应的时间单元指示信息指示的时间单元也为slot4，因此，终端可将PDSCH0的HARQ-ACK信息比特和PDSCH1的HARQ-ACK信息比特放在一个HARQ-ACK码本中，在slot4上进行反馈。相应的，图4中在slot4上HARQ-ACK码本对应的DCI，为DCI0和DCI1中PDCCH检测时机或PDCCH接收时间最靠后的PDCCH承载的DCI。例如，假设检测到DCI1的PDCCH检测时机最靠后，则DCI1为该HARQ-ACK码本对应的DCI。
一个HARQ-ACK码本所占时频资源所在的时间单元可由其包含的任一HARQ-ACK信息比特对应的时间单元指示信息来确定。本申请实施例，采用HARQ-ACK码本对应的DCI调度的下行数据的HARQ-ACK信息比特对应的时间单元指示信息，作为HARQ-ACK码本的时间单元指示信息为例进行阐述。简称为：HARQ-ACK码本的时间单元指示信息为该HARQ-ACK码本对应的DCI对应的时间单元指示信息。
在另一种实施方式中，一个HARQ-ACK码本所占时频资源所在的时间单元也可以由无线资源控制(radio resource control，RRC)信令配置。
HARQ-ACK码本所占的时频资源是基于该HARQ-ACK码本对应的DCI中的资源指示信息确定的，即该HARQ-ACK码本对应的DCI中资源指示信息用于确定该HARQ-ACK码本所占的资源。该资源包括时域、频域、码域资源等。其中，资源指示信息也可以为资源指示，或上行控制信道资源指示，或PUCCH资源指示。
网络设备通过高层信令，如RRC信令、媒体接入控制控制单元(medium access control control element，MAC CE)等，为终端配置上行控制信道资源池。该上行控制信道资源池包括多个上行控制信道资源集合。不同上行控制信道资源集合对应不同的反馈比特大小范围。可选的，上行控制信道资源池可以是基于高层信令配置的其他参数间接获得的，或者可以是高层信令直接配置的参数。
一种实施方式中，HARQ-ACK码本所占的时频资源是由HARQ-ACK码本的比特数以 及HARQ-ACK码本对应的DCI中资源指示信息确定的。终端可基于HARQ-ACK码本的比特数，从该上行控制信道资源池中确定一个上行控制信道资源集合。进而，终端可基于HARQ-ACK码本对应的DCI中资源指示信息的值，从选择的上行控制信道资源集合中，确定一个上行控制信道资源，作为HARQ-ACK码本所占的时频资源。
另一种实施方式，HARQ-ACK码本所占的时频资源是由HARQ-ACK码本的比特数、HARQ-ACK码本对应的DCI中资源指示信息以及承载该DCI的PDCCH所占据的CCE位置确定的。该实施方式可以解决上述上行控制信道资源集合包括的上行控制信道资源较多，DCI中资源指示信息无法指示完该集合中各上行控制信道资源的问题。即终端可以根据该资源指示信息以及承载DCI的PDCCH所占据的控制信道元素(control channel element，CCE)位置，从该上行控制信道资源集合确定一上行控制信道资源。
例如，一上行控制信道资源集合包括32个上行控制信道资源。DCI中资源指示信息为3比特，可分别表示8个上行控制信道资源。结合承载该DCI的PDCCH所占据的CCE位置，可以从该32个上行控制信道资源中确定一上行控制信道资源。这样，终端可基于HARQ-ACK码本的比特数，从该上行控制信道资源池中选择一个上行控制信道资源集合。然后，终端可利用承载HARQ-ACK码本对应的DCI的PDCCH所占据的CCE位置，以及HARQ-ACK码本对应的DCI中资源指示信息的3个比特的值，从该上行控制信道资源集合确定唯一的一个上行控制信道资源，作为该HARQ-ACK码本所占的时频资源。
例如，一上行控制信道资源集合包括32个上行控制信道资源。DCI中资源指示信息为3比特，可分别表示8个上行控制信道资源。结合承载该DCI的PDCCH所占据的CCE位置，可以从该32个上行控制信道资源中确定一上行控制信道资源。这样，终端可基于HARQ-ACK码本的比特数，从该上行控制信道资源池中选择一个上行控制信道资源集合。然后，终端可利用承载HARQ-ACK码本对应的DCI的PDCCH所占据的CCE位置，以及HARQ-ACK码本对应的DCI中资源指示信息的3个比特的值，从该上行控制信道资源集合确定唯一的一个上行控制信道资源，作为该HARQ-ACK码本所占的时频资源。
其中，终端设备可根据如下公式(1)以及该DCI的PDCCH所占据的CCE位置、该DCI中资源指示信息确定PUCCH资源的索引号r PUCCH。
Figure PCTCN2020109308-appb-000006
其中，N CCE,p是该DCI所在的CORESET中的CCE的总个数，是由高层信令配置的；
n CCE,p是承载该DCI的PDCCH所占据的CCE位置；
Δ PRI是该DCI中的资源指示信息，例如PUCCH资源指示域(resource indicator field)所指示的值；
R PUCCH是上行控制信道资源集合，如PUCCH资源集合中的总的PUCCH资源的个数。
该公式(1)相当于提供了PUCCH资源的索引号的两个偏移，比如，基于CCE位置确定的第二偏移，基于资源指示信息确定的第一偏移。从而，可基于该第一偏移和第二偏移确定一索引号，进而，确定PUCCH资源。
以R PUCCH等于16为例，代入公式(1)可获得如下公式：
Figure PCTCN2020109308-appb-000007
由于Δ PRI的取值范围为0～7，故Δ PRI不小于零，故该公式(2)可等效为：
Figure PCTCN2020109308-appb-000008
可见，公式(3)中，基于资源指示信息Δ PRI的取值范围0～7，可确定第一偏移为0～7。基于CCE位置的CCE index属于CCE的总个数N CCE,p中的前一半还是后一半，或者CCE index的值小于N CCE,p/2，还是大于或等于N CCE,p/2，确定第二偏移可以为0或1。故可获得如下表1所示的对应关系：

Figure PCTCN2020109308-appb-000009
可见，基于表1，可基于资源指示信息(有8个取值)和CCE位置(有2个取值的区间)能够指示PUCCH资源集合中的16个PUCCH资源。对于多个TRP来说，终端设备可基于每个TRP关联的DCI或对应的HARQ-ACK码本对应的DCI，读取资源指示信息以及承载该DCI的PDCCH所占据的CCE位置，进而确定每个TRP对应的PUCCH资源。
再例如，公式(1)可做如下解读：基于资源指示信息Δ PRI的取值范围0～7，即资源指示信息所指示的值具有A个，A等于8；基于阈值R PUCCH mod A，当资源指示信息Δ PRI小于该阈值时，第二偏移B1具有
Figure PCTCN2020109308-appb-000010
个取值，当资源指示信息Δ PRI大于或等于该阈值时，第二偏移B2具有
Figure PCTCN2020109308-appb-000011
个取值。其中，B1＝1+B2。也就是说，基于资源指示信息和CCE位置可指示
Figure PCTCN2020109308-appb-000012
个PUCCH资源。
以R PUCCH等于10为例，代入公式(1)可获得如下公式：
Figure PCTCN2020109308-appb-000013
其中，基于资源指示信息Δ PRI的取值范围0～7，以及该DCI所在的CCE index在CCE的总个数中前一半，还是后一半，基于公式(4)可获得如下表2：
表2
Figure PCTCN2020109308-appb-000014
如表2所示，在Δ PRI小于阈值2时，第二偏移有两行，有两个可选值，分别为0或1；在Δ PRI大于或等于阈值2时，第二偏移有一行，有一可选值为0。
又一种实施方式中，若上行控制信道资源集合中包括更多的PUCCH资源，则HARQ-ACK码本所占的时频资源是由HARQ-ACK码本对应的DCI中资源指示信息、承载该DCI的PDCCH所占据的CCE位置以及该HARQ-ACK码本关联的下行控制相关参数确定的。即该实施方式使得多个TRP各自都可以指示足够多的资源，保证各个TRP的调度灵活度。比如说，原来上行控制信道资源集合可配的资源个数是32，则各个TRP之间因为不能用一样的资源，导致了各个TRP的调度灵活地受限，比如TRP1只能用资源0～15，TRP2只能用16～32。那么如果总资源数允许上升到64，这样的话，每个TRP都可以用32个资 源，就能够保证各个TRP的调度PUCCH资源的灵活度了。
其中，该HARQ-ACK码本关联的下行控制相关参数为控制资源集合，该控制资源集合中具有高层参数(higher layer index)，因此，该实施方式中，终端设备根据HARQ-ACK码本对应的DCI中资源指示信息、承载该DCI的PDCCH所占据的CCE位置以及该higher layer index(简称index)确定该HARQ-ACK码本所占的时频资源。
可选的，该HARQ-ACK码本关联的控制资源集合CORESET可以为承载HARQ-ACK码本对应的DCI的PDCCH所在的控制资源集合CORESET。
请参阅图14，图14是本申请实施例提供一种上行控制信道资源确定方法的流程示意图。如图14所示，该上行控制信道资源确定方法包括：
501、终端设备接收下行控制信息DCI；
502、终端设备根据所述DCI中的资源指示信息、控制信道元素CCE位置和控制资源集合CORESET中高层参数，确定上行控制信道资源。
其中，所述CCE位置为所述DCI的物理下行控制信道PDCCH所占据的CCE资源对应的CCE起始位置。所述CORESET为所述DCI的PDCCH所在的控制资源集合。
其中，针对不同TRP的反馈信息，可分别基于反馈信息关联的下行控制信息，采用501和502相关的实施方式分别确定所对应的上行控制信道资源。其中，不同TRP关联的控制资源集合中的高层参数不同。
在一种实施方式中，终端设备根据该DCI中的资源指示信息和承载该DCI的PDCCH所占据的CCE位置确定第一资源编号；终端设备根据该第一资源编号和该CORESET中的高层参数的索引号，确定第二资源编号；终端设备根据该第二资源编号从上行控制信道资源集合中确定该HARQ-ACK码本所占的时频资源。
其中，一个控制资源集合(CORESET)组内的各CORESET中的高层参数的索引号相同，不同CORESET组内的CORESET中高层参数的索引号不同。其中：

其中，[x+0.5]表示对x四舍五入后取整。
该实施方式中，终端设备根据该DCI中的资源指示信息和承载该DCI的PDCCH所占 据的CCE位置确定第一资源编号r PUCCH，可采用以下公式确定，以上行控制信道资源为PUCCH资源为例：
Figure PCTCN2020109308-appb-000020
其中，N CCE,p是该DCI所在的CORESET中的CCE的总个数，是由高层信令配置的；
n CCE,p是承载该DCI的PDCCH所占据的CCE位置；
Δ PRI是该DCI中的资源指示信息(PUCCH resource indicator field,PRI)；
该设计中，R PUCCH基于上述公式(5)、或(6)、或(7)确定的该CORESET所在的CORESET组被分配的PUCCH资源的总个数。
例如，假设终端设备被配置的两个CORESET组，该两个CORESET组中高层参数的索引号分别为0和1，并将PUCCH资源集合中索引号为0至15的PUCCH资源分配给高层参数的索引号为0的CORESET组，记为PUCCH资源子集1；将PUCCH资源集合中索引号为16至31的PUCCH资源分配给高层参数的索引号为1的CORESET组，记为PUCCH资源子集2。其中，第一资源编号为PUCCH资源在PUCCH资源子集1或PUCCH资源子集2中的临时资源编号，如PUCCH资源子集1中索引号为0至15的PUCCH资源的第一资源编号依次为0至15；PUCCH资源子集2中索引号为16至31的PUCCH资源的第一资源编号依次为0至15。这样，假设终端设备根据上述公式(8)确定第一资源编号r PUCCH等于2，以及该HARQ-ACK码本关联的CORESET中高层参数的索引号为1，则可确定第二资源编号等于2+16，即18，因此，PUCCH资源为：PUCCH资源子集2中第一资源编号为2的PUCCH资源，即PUCCH资源集合中索引号为18的PUCCH资源。
在另一种实施方式中，与上述实施方式的不同之处在于，即使PUCCH资源集合中具有较多的PUCCH资源，也依旧可基于上述公式(8)来确定PUCCH资源，这样，上述公式(8)中的r PUCCH就为PUCCH资源集合中的索引号，从而能够确定出PUCCH资源。即终端设备可根据该DCI中的资源指示信息和承载该DCI的PDCCH所占据的CCE位置确定PUCCH资源。但若需不同的TRP的HARQ-ACK码本使用不同的PUCCH资源，则多个TRP之间需进行协商，以将不同TRP或不同HARQ-ACK码本对应的DCI中的资源指示信息和DCI的PDCCH所占据的CCE位置中的至少一个配置为不同。该设计适用于可选的CCE起始位置较多的情况，从而能够指示更多的PUCCH资源。例如，假设CCE起始位置为3个，资源指示信息为3比特，则基于CCE起始位置和资源指示信息最多可指示24个PUCCH资源。
该实施方式中，当终端设备被配置了多个CORESET组时，每个CORESET组中高层参数的索引号不同，则终端设备具有8个CCE起始位置时，资源指示信息为3比特，则基 于CCE起始位置和资源指示信息可指示大于24个的PUCCH资源，例如，可指示64个PUCCH资源。
在又一种实施方式中，可采用如下公式(9)以及HARQ-ACK码本对应的DCI中资源指示信息、承载该DCI的PDCCH所占据的CCE位置以及该HARQ-ACK码本关联的高层参数index的值确定HARQ-ACK码本所占的时频资源。
Figure PCTCN2020109308-appb-000021
其中，index取值为0或1，也可以表示终端设备被配置的多个控制资源集合组中第1个组的值或第2个组中的值。C为终端设备被配置的控制资源集合组的个数。
基于公式(9)，资源指示信息可对应第一偏移；CCE位置和index的值可确定第二偏移。
以R PUCCH等于32为例，资源指示信息Δ PRI的取值范围0～7，以及该DCI所在的CCE index在CCE的总个数中前一半，还是后一半，基于公式(9)可获得如下表3：

Figure PCTCN2020109308-appb-000023
与公式(9)的不同之处在于，基于CCE位置和index的值确定第二偏移的形式变化。
相应的，以R PUCCH等于32为例，资源指示信息Δ PRI的取值范围0～7，以及该DCI所在的CCE index在CCE的总个数中前一半，还是后一半，基于公式(10)可获得如下表4：

Figure PCTCN2020109308-appb-000025

Figure PCTCN2020109308-appb-000027
公式(12)与公式(11)不同之处在于，公式(12)中，基于资源指示信息Δ PRI和index的值确定第一偏移的具体方式不同。相应的，以R PUCCH等于32为例，资源指示信息Δ PRI的取值范围0～7，以及该DCI所在的CCE index在CCE的总个数中前一半，还是后一半，基于公式(12)可获得如下表6：
表6
Figure PCTCN2020109308-appb-000028
Figure PCTCN2020109308-appb-000029
一个PDCCH可占据一个或多个CCE。占据的CCE越多，则PDCCH的可靠性越高。一个CCE是由6个资源元素组(resource element group，REG)组成的，一个REG的资源是由频域上的一个资源块(resource block，RB)和时域上的一个符号组成的。各REG与各CCE之间具有映射关系，可以是直接映射，比如连续的6个REG组成一个CCE；或者可以是交织映射，比如将REG进行交织后映射到CCE等。
本申请实施例中，下行控制相关参数可以包括物理下行控制信道配置参数(physical downlink control channel config，PDCCH-Config)、控制资源集合(control resource sets，CORESET)或控制资源集合组(control resource sets group，CORESET group)等等。PDCCH-Config包括的参数用于检测候选的下行控制信道(physical downlink control channel,PDCCH)。CORESET用于定义可能检测到PDCCH的频域资源。
同一个网络设备的HARQ-ACK码本关联的一个或多个PDCCH所关联的下行控制相关参数相同。不同网络设备的HARQ-ACK码本分别关联的PDCCH所关联的下行控制相关参数不同。
其中，下行控制相关参数不同，也可以是指一网络设备配置了下行控制相关参数，另一个网络设备没有配置。比如，基于PDCCH关联的CORESET中是否包含高层参数(higher layer index)，可以确定包含该高层参数的CORESET关联的PDCCH调度的PDSCH对应的HARQ-ACK信息比特属于一个TRP的，不包含该高层参数的CORESET关联的PDCCH调度的PDSCH对应的HARQ-ACK信息比特属于另一个TRP的。
因此，终端可基于PDCCH关联的下行控制相关参数，区分出哪些PDCCH承载的DCI调度的下行数据的HARQ-ACK信息比特属于不同的HARQ-ACK码本，哪些PDCCH承载的DCI调度的下行数据的HARQ-ACK信息比特属于同一个HARQ-ACK码本。
本申请实施例中，第一反馈信息与第二反馈信息分别关联的下行控制相关参数不同。也就是说，第一反馈信息和第二反馈信息属于不同的网络设备。
比如，第一反馈信息关联的下行控制相关参数为控制资源集合1；第二反馈信息关联的下行控制相关参数为控制资源集合2。但控制资源集合1中的高层参数(higher layer index0)与控制资源集合2中的高层参数(higher layer index 1)不同。不同网络设备，其反馈信息关联的高层参数的取值不同。
再比如，控制资源集合1中没有配置高层参数(higher layer index)，控制资源集合2中配置了高层参数(higher layer index 1)，则也可认为第一反馈信息关联的下行控制相关参数与第二反馈信息关联的下行控制相关参数不同。
又比如，控制资源集合1与控制资源集合2中各配置了不同的传输配置指示(transmission configuration indication，TCI)状态，则也可认为第一反馈信息关联的下行控制相关参数与第二反馈信息关联的下行控制相关参数不同。
可选的，可基于第一反馈信息关联的下行控制相关参数以及第二反馈信息关联的下行控制相关参数，确定第一反馈信息与第二反馈信息之间的优先级。
比如，基于反馈信息关联的下行控制相关参数中是否包含特定的参数或特定的参数值，确定该反馈信息的优先级的高低。再比如，基于反馈信息关联的下行控制相关参数中一参数取值的大小，确定该反馈信息的优先级。其中，该参数取值可以为高层参数的取值，或者控制资源集合中TCI状态的取值(如索引号index)。再比如，基于反馈信息关联的一个或多个PDCCH分别调度的PDSCH中是否包含半静态调度(semi persistent scheduling，SPS)PDSCH，确定该反馈信息的优先级。再比如，基于反馈信息关联的一个或多个PDCCH分别调度的PDSCH中包含SPS PDSCH的个数，确定该反馈信息的优先级。
请参阅图4，图4是本申请公开的实施例提供的一种无线通信系统的示意图。如图4所示，无线通信系统可包括：多个网络设备(例如TRP)，一个或多个终端。其中：网络设备可用于在网络设备控制器(未示出)的控制下，通过无线接口与终端通信。在一些实施例中，所述网络设备控制器可以是核心网的一部分，也可以集成到网络设备中。网络设备之间可用于通过回程(backhaul)接口向核心网传输控制信息或者用户数据。具体的，如图4所示，TRP1与TRP2之间通过回程(backhaul)接口，直接地或者间接地，相互通信。另外，多个网络设备可以调度同一个终端，即多站协作传输场景。其中，回程(backhaul)接口可以是通过空口或有线连接。
如图4所示的无线通信系统中，TRP1和TRP2可分别发送不同的下行控制信息给终端，不同的下行控制信息承载在不同的物理下行控制信道(physical downlink control channel,PDCCH)上，调度各下行数据。
例如，假设高层信令指示多个时序偏移值K1set＝{k0＝4,k1＝3}，以及时间单元以时隙slot，以及上下行子载波间隔相同为例，如图5所示，TRP1通过PDCCH0承载的DCI0调度slot n传输PDSCH0，通过PDCCH1承载的DCI1调度slot n+1传输PDSCH1，终端基于上述所述的高层信令配置的时序偏移值或高层信令结合DCI0、DCI1分别指示的时序偏移值，确定PDSCH0和PDSCH1分别对应的HARQ-ACK信息比特可在一个HARQ-ACK码本1中在slot n+4上反馈。即该HARQ-ACK码本1包括PDSCH0的HARQ-ACK信息比特以及PDSCH1的HARQ-ACK信息比特。并且，该HARQ-ACK码本1关联的PDCCH为PDCCH0和PDCCH1。该HARQ-ACK码本1对应的DCI为PDCCH0和PDCCH1中PDCCH接收时机或PDCCH检测时机最靠后的PDCCH1承载的DCI1。该HARQ-ACK码本1所占时频资源是基于该HARQ-ACK码本1对应的DCI1中的资源指示信息确定的。该HARQ-ACK码本1所占时频资源所在的时间单元是slot n+4。
TRP2通过PDCCH2承载的DCI2调度slot n传输PDSCH2，通过PDCCH3承载的DCI3调度slot n+1传输PDSCH3，假设基于上述所述的高层信令或高层信令结合DCI的指示，获得需在slot n+4上反馈的HARQ-ACK码本2。该HARQ-ACK码本2包括PDSCH2的HARQ-ACK信息比特以及PDSCH3的HARQ-ACK信息比特。并且，该HARQ-ACK码本2关联的PDCCH为PDCCH2和PDCCH3。该HARQ-ACK码本2对应的DCI为PDCCH2和PDCCH3中PDCCH接收时机或PDCCH检测时机最靠后的PDCCH3承载的DCI3。该HARQ-ACK码本2所占时频资源是基于该HARQ-ACK码本2对应的DCI3中的资源指示 信息确定的。该HARQ-ACK码本2所占时频资源所在的时间单元是slot n+4。
可见，对于终端来说，同一个上行时间单元，存在多个与不同TRP关联的HARQ-ACK码本，终端在何时对该多个HARQ-ACK码本生成联合反馈信息，何时分别反馈多个HARQ-ACK码本中至少一个，因此，本申请提供一种反馈信息传输方法，能够针对多个HARQ-ACK码本的情况，确定何时采用独立反馈，何时采用联合反馈。以下结合附图进行阐述。
请参阅图6，图6是本申请提供的一种反馈信息传输方法的流程示意图。如图6所示，该反馈信息传输方法可以包括以下步骤：
101、终端确定第一反馈信息对应的第一下行控制信息DCI，以及第二反馈信息对应的第二DCI。
其中，第一资源指示信息与第二资源指示信息相同时，终端可执行步骤102；第一资源指示信息与所述第二资源指示信息不同时，终端可执行步骤103和步骤104中的至少一个步骤。
102、终端基于第一反馈信息和第二反馈信息生成联合反馈信息。
103、所述终端反馈第一反馈信息。
104、终端反馈第二反馈信息。
可见，终端在不需要接收额外的信令指示，就能够确定多个反馈信息之间的反馈方式，节省了信令开销。另外，终端生成联合反馈信息的方式与终端生成独立反馈信息的方式，对于终端来说，两种方式之间的差别较小，有利于终端可分别针对不同的网络设备确定两个反馈信息后，再确定反馈方式。
终端可基于上述HARQ-ACK码本对应的DCI的相关阐述，确定第一反馈信息对应的第一DCI以及第二反馈信息对应的第二DCI。其中，第一反馈信息对应的第一DCI可以为该第一反馈信息的最后一个DCI。相应的，第二反馈信息对应的第二DCI可以为该第二反馈信息的最后一个DCI。
在一种实施方式中，终端确定第一反馈信息对应的第一DCI、以及第二反馈信息对应的第二DCI，包括：终端基于第一反馈信息关联的各下行控制信道的下行控制信道检测时机，确定所述第一反馈信息对应的第一DCI；终端基于第二反馈信息关联的各下行控制信道的下行控制信道检测时机，确定所述第二反馈信息对应的第二DCI。
其中，所述第一DCI为第一反馈信息关联的各下行控制信道中下行控制信道检测时机最靠后的下行控制信道所携带的DCI，也就是说，第一DCI为该第一反馈信息对应的最后一个DCI。所述第二DCI为第二反馈信息关联的各下行控制信道中下行控制信道检测时机最靠后的下行控制信道所携带的DCI，也就是说，第二DCI为该第二反馈信息对应的最后一个DCI。
在另一种实施方式中，终端确定第一反馈信息对应的第一DCI、以及第二反馈信息对应的第二DCI，包括：终端基于第一反馈信息关联的各下行控制信道的下行控制信道接收时间，确定所述第一反馈信息对应的第一DCI；终端基于第二反馈信息关联的各下行控制信道的下行控制信道接收时间，确定所述第二反馈信息对应的第二DCI。
其中，所述第一DCI为第一反馈信息关联的各下行控制信道中下行控制信道接收时间 最靠后的下行控制信道所携带的DCI；所述第二DCI为第二反馈信息关联的各下行控制信道中下行控制信道接收时间最靠后的下行控制信道所携带的DCI。
在一种实施方式中，终端基于第一反馈信息和第二反馈信息生成联合反馈信息，可以为：终端基于第一反馈信息关联的下行控制相关参数以及第二反馈信息关联的下行控制相关参数，将第一反馈信息和第二反馈信息生成联合反馈信息。
例如，第一反馈信息和第二反馈信息合并的顺序可基于两者的优先级来确定。比如，优先级高的反馈信息可以排列在之前，优先级低的反馈信息可排列在之后。或者，优先级高的反馈信息可以排列在之后，优先级低的反馈信息可排列在之前。
其中，第一反馈信息和第二反馈信息之间的优先级可基于上述所述的下行控制相关参数确定。如上所述，可通过协议预定义或RRC信令配置的方式设定各下行控制相关参数与反馈信息的优先级之间的关系。
比如，如图7所示，第一反馈信息关联的下行控制相关参数为控制资源集合1；第二反馈信息关联的下行控制相关参数为控制资源集合2。控制资源集合1中配置高层参数(higher layer index)0，控制资源集合2中配置了高层参数(higher layer index 1)，可约定第一反馈信息关联的下行控制相关参数的优先级低于第二反馈信息关联的下行控制相关参数的优先级。故图7中，可将第一反馈信息合并在第二反馈信息之后。
再比如，第一反馈信息关联的控制资源集合1中没有配置高层参数(higher layer index)，第二反馈信息关联的控制资源集合2中配置了高层参数(higher layer index 1)，则第一反馈信息可以排列在第二反馈信息之前。
又比如，控制资源集合1与控制资源集合2中各配置了不同的传输配置指示(transmission configuration indication，TCI)状态，则TCI状态的索引号大的反馈信息可以排列在TCI状态的索引号小的反馈信息之前。
又比如，基于反馈信息关联的下行控制相关参数中是否包含特定的参数或特定的参数值，确定该反馈信息在联合反馈信息中的排列顺序。
又比如，基于反馈信息关联的下行控制相关参数中一参数取值的大小，确定该反馈信息在联合反馈信息中的排列顺序。
又比如，基于反馈信息关联的一个或多个PDCCH分别调度的PDSCH中是否包含半静态调度(semi persistent scheduling，SPS)PDSCH，确定该反馈信息在联合反馈信息中的排列顺序。
又比如，基于反馈信息关联的一个或多个PDCCH分别调度的PDSCH中包含SPS PDSCH的个数，确定该反馈信息在联合反馈信息中的排列顺序。
其中，第一反馈信息和第二反馈信息内各HARQ-ACK信息比特的排列方式可基于各HARQ-ACK信息比特对应的PDSCH接收时机、下行数据所在的时隙的索引号、传输下行数据的小区标识、等等确定。本申请实施例不做限定。
以一个HARQ-ACK码本内HARQ-ACK信息比特排列为例。当终端被配置了多个小区时，不同小区对应的PDSCH接收时机的排列顺序基于小区标识的大小顺序进行排列。同一小区的不同时隙之间，PDSCH接收时机的排列顺序基于各下行数据所在时隙的索引号的顺序来排列。同一时隙中，PDSCH接收时机的排列顺序基于PDSCH接收时机对应的时域 资源分配方式被标记为PDSCH接收时机的标记顺序来排列。进而，基于排列后的PDSCH接收时机的顺序，排列各PDSCH接收时机对应的HARQ-ACK信息比特，获得HARQ-ACK码本。
假设终端被配置了小区1和小区2，小区1中PDSCH0所在的时隙和PDSCH1所在的时隙均为时隙0，PDSCH2所在的时隙为时隙1；PDSCH0对应的PDSCH接收时机为PDSCH接收时机0；PDSCH1对应的PDSCH接收时机为PDSCH接收时机1；PDSCH2对应的PDSCH接收时机为PDSCH接收时机2。小区2中PDSCH3所在的时隙为时隙0，PDSCH3对应的PDSCH接收时机为PDSCH接收时机3。以小区标识从大到小排列，以时隙的索引号从大到小排列以及PDSCH接收时机也以从大到小排列，则排列后的PDSCH接收时机顺序可以为：[PDSCH接收时机3][(PDSCH接收时机2)(PDSCH接收时机1，PDSCH接收时机0)]。
在一种实施方式中，终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个，可以为：终端基于第一反馈信息的时间单元指示信息以及第一资源指示信息确定第一反馈信息所占的时频资源和所在的时间单元；以及基于第二反馈信息的时间单元指示信息以及第二资源指示信息确定第二反馈信息所占的时频资源和所在的时间单元；进而，终端可在第一反馈信息所在的时间单元中第一反馈信息所占的时频资源上发送第一反馈信息；以及在第二反馈信息所在的时间单元中第二反馈信息所占的时频资源上发送第二反馈信息，即执行步骤103和步骤104。
在另一种实施方式中，第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠时，终端可基于第一反馈信息与第二反馈信息之间的优先级，选择反馈其中一个反馈信息。
比如，所述第一反馈信息与所述第二反馈信息满足以下一个或多个条件：所述第一反馈信息的优先级高于所述第二反馈信息的优先级；所述第一反馈信息关联的下行控制相关参数的优先级高于所述第二反馈信息关联的下行控制相关参数的优先级。那么，第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠时，终端可反馈第一反馈信息，不反馈第二反馈信息，即执行步骤103。
在又一种实施方式中，第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠时，终端可基于第一反馈信息与第二反馈信息分别关联的下行控制相关参数，选择反馈其中一个反馈信息。
比如，所述第一反馈信息关联的控制资源集合中高层参数的索引号大于所述第二反馈信息关联的控制资源集合中高层参数的索引号；终端可反馈第一反馈信息，不反馈第二反馈信息。例如，第一反馈信息关联的下行控制相关参数为控制资源集合1；第二反馈信息关联的下行控制相关参数为控制资源集合2。控制资源集合1中配置高层参数(higher layer index)0，控制资源集合2中配置了高层参数(higher layer index 1)，则第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠时，终端可反馈第二反馈信息，不反馈第一反馈信息，即执行步骤104。
再比如，所述第一反馈信息关联的控制资源集合中高层参数的索引号小于所述第二反馈信息关联的控制资源集合中高层参数的索引号；则上述例子中，终端可反馈第一反馈信 息，不反馈第二反馈信息，即执行步骤103。
又比如，基于反馈信息关联的下行控制相关参数中是否包含特定类型的参数或特定的参数值，确定在时频资源重叠时是否优先反馈该反馈信息。例如，第一反馈信息关联的控制资源集合1中没有配置高层参数(higher layer index)，第二反馈信息关联的控制资源集合2中配置了高层参数(higher layer index 1)，则在第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠时，终端可反馈第二反馈信息，不反馈第一反馈信息，即执行步骤104。
又比如，控制资源集合1与控制资源集合2中各配置了不同的传输配置指示(transmission configuration indication，TCI)状态，终端可基于TCI状态的索引号的大小，确定多个反馈信息所占的时频资源重叠时，优先反馈的反馈信息。
其中，第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠可以包括部分重叠和全部重叠。
可选的，第一反馈信息所占的时频资源与第二反馈信息所占的时频资源发生重叠，可以包括：第一反馈信息所占的时频资源与第二反馈信息所占的时频资源在时域上存在重叠，或者在频域上存在重叠，或者在时频域上存在重叠。
可见，该实施例中，终端可基于第一反馈信息的第一资源指示信息与第二反馈信息的第二资源指示信息是否相同，确定对第一反馈信息和第二反馈信息生成联合反馈信息，还是分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。而不需要额外的信令指示，从而有利于节省信令开销。
例如，上述图5中，HARQ-ACK码本1所占时频资源与HARQ-ACK码本2所占时频资源相同，则终端将HARQ-ACK码本1和HARQ-ACK码本2合并生成一个HARQ-ACK码本。其中，该HARQ-ACK码本所占时频资源所在的时间单元还为时隙n+4；该HARQ-ACK码本所占时频资源可基于上述所述的规则，基于该HARQ-ACK码本的比特数、该HARQ-ACK码本关联的DCI中的资源指示信息来确定，或基于该HARQ-ACK码本的比特数、该HARQ-ACK码本关联的DCI中的资源指示信息以及承载该DCI的PDCCH所占据的CCE位置来确定。
其中，联合反馈信息对应的DCI为基于该联合反馈信息关联的各PDCCH的PDCCH接收时间或PDCCH检测时机确定的。该联合反馈信息关联的各PDCCH包括第一反馈信息关联的各PDCCH以及第二反馈信息关联的各PDCCH。例如，联合反馈信息对应的DCI为该联合反馈信息关联的各PDCCH中，PDCCH接收时间或PDCCH检测时机最靠后的PDCCH承载的DCI。
相应的，上述图5中，HARQ-ACK码本1和HARQ-ACK码本2合并生成一个HARQ-ACK码本对应的DCI为：PDCCH0、PDCCH1、PDCCH2、PDCCH3中PDCCH接收时间或PDCCH检测时机最靠后的PDCCH承载的DCI。
请参阅图8，图8是本申请实施例提供的另一种反馈信息传输方法的流程示意图，如图8所示，该反馈信息传输方法可以包括以下步骤：
201、终端判断第一时间单元指示信息指示的时间单元与第二时间单元指示信息指示的时间单元是否相同；若相同，则执行步骤202，若不相同，则执行步骤204；
所述第一时间单元指示信息，用于指示第一反馈信息所占时频资源所在的时间单元；所述第二时间单元指示信息，用于指示第二反馈信息所占时频资源所在的时间单元。
202、终端判断第一资源指示信息与第二资源指示信息是否相同，若相同，则执行步骤203；若不相同，则执行步骤204；
203、终端基于所述第一反馈信息和所述第二反馈信息生成联合反馈信息。
204、终端分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。
可见，该实施例中，终端可基于反馈信息的时间单元指示信息以及资源指示信息，确定对第一反馈信息和第二反馈信息生成联合反馈信息，还是分别反馈所述第一反馈信息和所述第二反馈信息中的至少一个。而不需要额外的信令指示，从而有利于节省信令开销。
例如，如图9所示，图9与图5的不同之处在于，高层信令配置的时序偏移值还包括k2＝2，TRP1通过PDCCH0承载的DCI0调度slot n传输PDSCH0，通过PDCCH1承载的DCI1调度slot n+1传输PDSCH1，终端基于上述所述的高层信令配置的时序偏移值或高层信令结合DCI0、DCI1分别指示的时序偏移值，确定PDSCH0和PDSCH1分别对应的HARQ-ACK信息比特可在一个HARQ-ACK码本1中在slot n+3上反馈。即该HARQ-ACK码本1所占时频资源所在的时间单元是slot n+3。因此，针对图9，终端可分别反馈HARQ-ACK码本1和HARQ-ACK码本2。
在一种实施方式中，终端判断第一反馈信息的比特数与所述第二反馈信息的比特数是否分别对应同一上行控制信道资源集合。比如，上行控制信道资源集合1对应的反馈比特数范围为零到2个比特之间，如[0,2]；上行控制信道资源集合2对应的反馈比特数范围为2比特到3比特之间，如(2,3]。第一反馈信息的比特数与第二反馈信息的比特数均属于同一反馈比特数范围时，可认为第一反馈信息的比特数与第二反馈信息的比特数分别对应同一个上行控制信道资源集合。
若分别对应同一上行控制信道资源集合，可执行步骤202；若不对应同一上行控制信道资源集合，即分别对应不同的上行控制信道资源集合，可执行步骤204。
在一种实施方式中，如前文所述，当反馈信息的比特数对应的上行控制信道资源集合中，包括的上行控制信道资源的个数较多，则终端还需基于承载反馈信息对应的DCI的PDCCH所占据的CCE位置，确定该反馈信息所占时域资源。比如，终端判断第一控制信道元素CCE位置与第二CCE位置是否相同；若相同，则执行步骤202，若不同，则执行步骤204。所述第一CCE位置，为承载所述第一DCI的下行控制信道所占据的控制信道元素CCE的位置；所述第二CCE位置，为承载所述第二DCI的下行控制信道所占据的控制信道元素CCE的位置。
可见，终端判断次数越多，终端所确定的反馈信息的反馈方式就更加匹配反馈信息本身的特点，因此，终端和网络设备可以通过协议预定义的方式，选择上述哪些实施方式以确定对反馈信息何时进行联合反馈，何时进行分别反馈。或者，网络设备还可以根据终端的处理能力，指示终端采用上述图6、图8所示的相关实施方式中哪些操作，来确定何时进行联合反馈，何时进行分别反馈。
另外，图6和图8所示的反馈信息传输方法中，终端可将联合反馈信息分别发送给各网络设备，也可以发送给其中一个网络设备。终端分别反馈所述第一反馈信息和所述第二 反馈信息中的至少一个给对应的网络设备。
请参阅图10，图10是本申请实施例提供的又一种反馈信息传输方法的流程示意图。图10是从网络设备侧的角度进行阐述的。
301、网络设备确定第一反馈信息对应的第一下行控制信息DCI，以及第二反馈信息对应的第二DCI；
302、所述第一资源指示信息与所述第二资源指示信息相同时，所述网络设备确定所述终端设备反馈的反馈信息是基于所述第一反馈信息和所述第二反馈信息生成的联合反馈信息；
303、所述第一资源指示信息与所述第二资源指示信息不相同时，所述网络设备确定所述终端设备反馈的第一反馈信息或第二反馈信息是独立反馈的。
网络设备确定终端设备反馈的反馈信息是基于所述第一反馈信息和所述第二反馈信息生成的联合反馈信息时，网络设备可接收终端在联合反馈信息对应的时频资源上发送的联合反馈信息，并且网络设备能够在相应的比特位置上解析自己的信息或解析出联合反馈信息。若解析出联合反馈信息的情况，网络设备还可以将联合反馈信息中其他网络设备关联的反馈信息发送给对应的其他网络设备。
例如，图7所示，假设第一反馈信息关联TRP1，第二反馈信息关联TRP2。TRP1能够基于自身关联的下行控制相关参数，能够从联合反馈信息中解析出自身的第一反馈信息；相应的，TRP2也可以接收到该联合反馈信息，能够根据自身关联的下行控制相关参数，从该联合反馈信息中解析出自身的第二反馈信息。或者，TRP1基于自身关联的下行控制相关参数以及TRP2关联的下行控制相关参数，从联合反馈信息中解析出第一反馈信息和第二反馈信息；并将第二反馈信息发送给TRP2。
网络设备确定所述终端设备反馈的第一反馈信息或第二反馈信息是独立反馈的，则网络设备可接收终端在该网络设备关联的反馈信息所占的时频资源上发送的反馈信息。比如，假设第一反馈信息关联TRP1，第二反馈信息关联TRP2。TRP1可接收终端在第一反馈信息所占的时频资源上发送的第一反馈信息，和/或，TRP2接收终端在第二反馈信息所占的时频资源上发送的第二反馈信息。比如，当第一反馈信息与第二反馈信息分别所占的时频资源发生重叠时，则TRP1和TRP2中可能存在其中一个无法接收到反馈信息。在一种实施方式中，网络设备确定第一反馈信息与第二反馈信息分别所占的时频资源发生重叠时，可进一步基于第一反馈信息和第二反馈信息分别关联的下行控制相关参数，或者基于第一反馈信息和第二反馈信息之间的优先级高低，确定出终端发送第一反馈信息和第二反馈信息中的哪一个。具体的，可参见上述方法实施例中，终端如何基于第一反馈信息与第二反馈信息之间的优先级，或者分别关联的下行控制相关参数，确定发送第一反馈信息和第二反馈信息中哪一个，以及不发送第一反馈信息和第二反馈信息中哪一个。
在一种实施方式中，所述第一资源指示信息与所述第二资源指示信息不相同时，所述网络设备确定所述终端设备反馈的第一反馈信息或第二反馈信息是独立反馈的，包括：所述第一资源指示信息指示的时频资源与所述第二资源指示信息指示的时频资源在时域上存在重叠时，所述网络设备确定所述终端反馈所述第一反馈信息，不反馈所述第二反馈信息。
在另一种实施方式中，所述第一资源指示信息与所述第二资源指示信息不相同时，所 述网络设备确定所述终端设备反馈的第一反馈信息或第二反馈信息是独立反馈的，包括：所述第一资源指示信息指示的时频资源与所述第二资源指示信息指示的时频资源在时域上不存在重叠时，所述网络设备确定所述终端分别反馈所述第一反馈信息，以及所述第二反馈信息。
可见，网络设备能够基于终端设备侧类似的规则，确定终端反馈的反馈信息是基于所述第一反馈信息和所述第二反馈信息生成的联合反馈信息，还是终端反馈的第一反馈信息或第二反馈信息是独立反馈的。具体的可以参见上述图6至图9所示的相关内容。
请参阅图11，图11是本申请实施例提供的又一种反馈信息传输方法的流程示意图。图11所示的反馈信息传输方法与图8相比，是从网络设备侧的角度阐述，该反馈信息传输方法可以包括以下步骤：
401、网络设备判断第一时间单元指示信息指示的时间单元与第二时间单元指示信息指示的时间单元是否相同；若相同，则执行步骤202，若不相同，则执行步骤204；
所述第一时间单元指示信息，用于指示第一反馈信息所占时频资源所在的时间单元；所述第二时间单元指示信息，用于指示第二反馈信息所占时频资源所在的时间单元。
402、网络设备判断第一资源指示信息与第二资源指示信息是否相同，若相同，则执行步骤203；若不相同，则执行步骤204；
403、网络设备确定所述终端设备反馈的反馈信息是基于所述第一反馈信息和所述第二反馈信息生成的联合反馈信息。
404、网络设备确定所述终端设备反馈的第一反馈信息或第二反馈信息是独立反馈的。
图11所示的实施例中，网络设备确定终端的反馈方式是联合反馈，还是独立反馈之后的相关操作，可参见上述图10所述的相关内容，这里不再详述。
可见，网络设备能够基于终端设备侧类似的规则，确定终端反馈的反馈信息是基于所述第一反馈信息和所述第二反馈信息生成的联合反馈信息，还是终端反馈的第一反馈信息或第二反馈信息是独立反馈的。从而，使得网络设备能够对终端反馈的反馈信息进行正确译码。
图10和图11的其他相关内容，可参考上述图6至图9所示的相关内容。此处不再详述。
