Description

上行控制信息的发送、接收方法和装置
本申请要求于2018年03月02日提交中国专利局、申请号为201810176133.2、申请名称为“上行控制信息的发送、接收方法和装置”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，尤其涉及一种上行控制信息的发送、接收方法和装置。
背景技术
第五代(5 Generation，5G)移动通信系统中，基站支持在一个时隙(slot)内为一个用户设备(User Equipment，UE)发送两个物理下行控制信道(Physical Downlink Control Channel，PDCCH)，该两个PDCCH均为该UE调度物理下行共享信道(Physical Downlink Shared Channel，PDSCH)资源。
一种实现方式中，基站包括两个天线阵面(Panel)：天线Panel1和天线Panel2，每个天线Panel由多个天线阵元组成，不同天线Panel在空间上可以相距较远，不同天线Panel可以发送不同的波束(beam)。在同一slot内，天线Panel1通过下行Beam1向UE发送PDCCH0以及该PDCCH0所调度的传输块(Transmission Block，TB)0，天线Panel2通过下行Beam2向UE发送PDCCH1以及该PDCCH1所调度的TB1。当UE接收到两个天线Panel所发送的PDCCH以及TB后，需要向基站反馈两个TB的混合自动重传确认请求(Hybrid Automatic Repeat request，HARQ)信息，该HARQ反馈信息可以为确认(Acknowledgement)或非确认(Negative Acknowledgement)。现有技术中，UE接收到两个PDCCH以及TB后，分别向两个天线Panel发送PUCCH，每个PUCCH承载对应天线Panel所发送TB的HARQ反馈信息。例如，UE通过上行Beam1向天线Panel1传输PUCCH0，PUCCH0承载着TB0的HARQ反馈信息；UE通过上行Beam2向天线Panel2传输PUCCH1，PUCCH1承载着TB1的HARQ反馈信息。基站对这两个天线Panel接收到的PUCCH信号进行合并处理。
上述方法中，UE使用上行波束向对应天线Panel传输PUCCH时，单个上行波束在扇区的覆盖面积较小，且高载频的路径损耗较大，如果上行波束传输信号受到遮挡，很容易导致上行波束链接失效，会使对应天线Panel无法接收到PUCCH，从而使得基站无法接收到TB的HARQ反馈信息。

具体实施方式
本申请实施例提供一种上行控制信息的发送、接收方法，本申请实施例的方法可以应用在长期演进(long term system，LTE)系统中，也可以应用在5G系统中，5G系统也称为新无线通信系统、新接入(New Radio，NR)系统或者下一代移动通信系统。
图1为本申请实施例适用的一种网络架构的示意图，如图1所示，该网络架构包括终端设备和基站，该基站可以为分布式基站，分布式基站将传统的宏基站设备按照功能划分为两个功能模块：基带单元(Base Band Unit，BBU)和射频远端单元(Remote Radio Unit，RRU)，其中，BBU用于完成基带、主控、传输、时钟等功能，RRU用 于完成收发信号、功放、滤波等功能。在网络部署时，将BBU与核心网、无线网络控制设备集中在中心机房内，通过光纤与规划站点上部署的RRU进行连接，完成网络覆盖，节省了常规解决方案所需要的大量机房，从而降低建设维护成本、提高效率。图1所示架构中，基站为分布式基站，当然，本申请实施例中，不对基站的形态做限制，基站也可以为BBU和RRU功能集成在一起的集成基站。
该终端设备可以是：手机、电脑，还可以为蜂窝电话、无绳电话、会话发起协议(session initiation protocol，SIP)电话、智能电话、无线本地环路(wireless local loop，WLL)站、个人数字助理(personal digital assistant，PDA)、电脑、膝上型计算机、手持式通信设备、手持式计算设备、卫星无线设备、无线调制解调器卡、电视机顶盒(set top box，STB)、车载设备、可穿戴设备、智能家居设备、用于在无线系统上进行通信的其它设备等。
NR系统中引入了更高的载波频率(以下简称载频)，待选的载频范围包括30GHz，60GHz等附近的载频。由于高载频信号在自由空间的衰落更大，即高载频的路径损耗较大，因此，NR系统中的具有高载频的基站的小区内会出现覆盖空洞。为了满足覆盖要求，NR系统中的基站需要在每个扇区分时间发送多个定向波束(Beam)，利用波束赋形技术将天线方向图的主瓣方向对准目标，从而保证该多个波束可以覆盖整个扇区。其中一种多波束传输的实现方式为多天线Panel(阵面)，每个天线Panel由多个天线阵元组成。不同天线Panel在空间上可以相距较远，不同天线Panel可以发送不同的波束。
图1所示网络架构中，基站使用两个RRU，每个RRU连接有天线Panel，每个RRU的信号由连接的天线Panel发送，RRU通过前向回传(Fronthaul)与BBU通信。基站的两个天线Panel在一个slot内为分别向一个终端设备发送两个PDCCH以及该PDCCH所调度的TB，终端设备接收到两个PDCCH以及TB后，分别向两个天线Panel发送PUCCH信号，每个PUCCH承载对应天线Panel所发送TB的HARQ反馈信息，该HARQ反馈信息为ACK消息或NACK消息。当这两个天线Panel接收到对应的PUCCH信号后，RRU通过fronthaul将PUCCH信号回传给该基站的BBU进行处理。
其中，不同天线Panel所发送波束的天线端口(antenna port)的信道特征互不相同，因此，天线端口所对应的参考信号(Reference Signal)的准共同定位(Quasi Co-Located，QCL)信息将不同。扇区覆盖范围内的终端设备可以同时检测到一个基站通过多个波束发送的信号。
天线端口是逻辑上的概念，一个天线端口可以是一个物理发射天线，也可以是多个物理发射天线的合并。在这两种情况下，终端设备的接收机(receiver)都不会去分辨来自同一个天线端口的信号，因为从终端的角度，不管天线端口是由单个物理发射天线形成的，还是由多个物理发射天线合并而成的，该天线端口对应的参考信号就定义了该天线端口，终端设备根据该参考信号得到该天线端口的信道估计。每个天线端口有其独自的参考信号，终端设备需要根据天线端口对应的参考信号进行信道估计和数据解调。一般而言，物理下行控制信道(Physical Downlink Control Channel，PDCCH)、物理下行共享信道(Physical Downlink Shared Channel，PDSCH)、物理上行控制信道(Physical Uplink Control Channel，PUCCH)、物理上行共享信道(Physical Uplink  Shared Channel，PUSCH)均有自己独自的参考信号，对应不同的天线端口。
两个信号(例如两个PDCCH)从两个不同的天线端口发送，两个信号所经历的信道可能有很多相同的大尺度特征，比如多普勒频移、平均时延和时延扩展等。因此对于天线端口引入了QCL的概念，如果不同天线端口被认为是QCL，接收机则假定对应于不同天线端口的信道具有某些相同的大尺度特征，这样有利于接收机进行信道估计。不同天线端口的QCL关系由天线端口所对应的参考信号的QCL信息来表示的。参考信号的QCL信息表示该参考信号与其它参考信号是QCL的，即这些参考信号的QCL类型以及对应的QCL参数是一样的，QCL类型以及参数如表1所示：
表1
QCL type QCL参数
QCL-TypeA {多普勒频移，多普勒扩展，平均时延,时延扩展}
QCL-TypeB {多普勒频移，多普勒扩展}
QCL-TypeC {平均时延，多普勒扩展}
QCL-TypeD {空间参数}
一般而言，如果两个天线端口对应的物理天线处于相同位置，则它们是QCL的。而如果两个天线端口对应的物理天线处于不同位置，则它们不是QCL的。
现有技术中，终端设备在每个PUCCH上只携带一个TB的HARQ反馈信息,由于单个上行波束在扇区的覆盖面积较小，且高载频的路径损耗较大，如果上行波束传输信号受到遮挡，很容易导致上行波束链接失效，会使对应天线Panel无法接收到PUCCH，从而无法接收到TB的HARQ反馈信息。
基于上述所示的网络架构，本申请提供一种上行控制信息的发送方法，旨在解决现有技术中基站无法接收到终端设备反馈的TB的HARQ反馈信息。下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个示例性的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图，对本申请的实施例进行描述。以下实施例可以用于多天线Panel传输，也可以用于多TRP(Transmission Reception Point，传输接收点)传输。
图2为本申请实施例一提供的上行控制信息的发送方法的流程图，如图2所示，本实施例提供的方法包括以下步骤：
步骤S101、终端设备接收网络设备发送的第一PDCCH和第二PDCCH，第一PDCCH和第二PDCCH在同一时间单元内传输，第一PDCCH指示第一PUCCH资源且用于调度第一下行TB，第二PDCCH指示第二PUCCH资源且用于调度第二下行TB。
本申请实施例中该网络设备可以为基站，该基站可以采用图1所示的分布式架构。网络设备在同一时间单元内向终端设备发送第一PDCCH和第二PDCCH，其中，第一PDCCH和第二PDCCH通过不同的波束发送，例如，基站通过第一波束向终端设备发送第一PDCCH，同时通过第二波束向终端设备发送第二PDCCH。
其中，第一PDCCH用于指示第一PUCCH资源，并调度第一下行TB，第二PDCCH用于指示第二PUCCH资源，并调度第二下行TB，因此，第一下行TB和第二下行TB 也在该时间单元内传输。因此，终端设备同时接收到第一PDCCH和第一下行TB，以及第二PDCCH和第二下行TB。终端设备在接收第一PDCCH和第二PDCCH之前，接收基站通过高层信令发送的配置信息，该配置信息用于配置终端设备在同一时间单元内接收两个用于调度下行数据的PDCCH。
可选的，第一PDCCH、第二PDCCH、第一下行TB和第二下行TB均在同一载波中传输。
可选的，第一下行TB和第二TB可在同一时间单元传输。
可选的，所述PDCCH调度的所述TB为时隙级的(slot scheduling)，即所述TB所在PDSCH的映射类型为PDSCH mapping type A。
可选的，所述PDCCH调度的所述TB为非时隙级的(non-slot scheduling)，即所述TB所在PDSCH的映射类型为PDSCH mapping type B。
该时间单元可以是子帧或时隙，还可以是迷你子帧或迷你时隙(Mini-slot，例如当PDSCH为Non-slot调度的时候)，也可以是时域符号，例如，正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号。
对于PDCCH指示PUCCH资源，基站通过第一PDCCH和第二PDCCH所承载的下行控制信息(Downlink Control Information，DCI)中的上行资源指示域(即PUCCH resource indicator域(PUCCH资源指示域))指示PUCCH资源的索引号，终端设备根据PUCCH资源索引号以及其他参数来确认PUCCH资源。在NR系统中，基站给终端设备最多配置四个PUCCH资源集合,每个PUCCH资源集合内包含4～8个PUCCH资源，每个PUCCH资源具有对应的索引号，PUCCH资源的索引号由高层信令PUCCH-resource-index来配置。同时，基站通过高层信令配置PUCCH资源集合内每个PUCCH资源的相关参数，PUCCH资源的相关参数包括：PUCCH资源的起始OFDM符号索引，OFDM符号数量，PRB数量以及PUCCH的DMRS信号与其它参考信号(如SRS、CSI-RS)的QCL信息。
现有技术中，终端设备可以根据所传输上行控制信息(Uplink Control Information，UCI)的比特数来决定PUCCH资源所在的一个PUCCH资源集合，同时基站通过PDCCH所承载的DCI中的PUCCH resource indicator域来指示PUCCH资源的索引号。当PUCCH资源集合中的PUCCH资源超过四个时，每个PUCCH resource indicator域的值能同时对应两个PUCCH资源，此时终端设备可通过其它参数(比如PDCCH的起始控制信道元素(Control Channel Element，CCE)编号值)从两个PUCCH资源中选择一个PUCCH资源来传输UCI。
可选的，每个PUCCH resource indicator域的值对应一个PUCCH资源，此时，终端设备直接根据PUCCH resource indicator域的值对应的PUCCH资源来传输UCI。
表2为PUCCH资源指示域的值与PUCCH资源集合中PUCCH资源的映射关系的一种示意图，表2如下所示：
表2
Figure PCTCN2019076689-appb-000001
Figure PCTCN2019076689-appb-000002
表2中，第一列为2比特的PUCCH resource indicator域的值，2比特共可以指示四种状态“00”、“01”、“10”、“11”。第二列中，每个PUCCH resource indicator域的值对应一个PUCCH资源集合中相应索引号的PUCCH资源。第三列中，每个PUCCH resource indicator域的值对应两个PUCCH资源集合中相应索引号的PUCCH资源，该两个PUCCH资源集合内索引号相同的PUCCH资源的DMRS信号的QCL信息是不同的，即发送这两个PUCCH的上行波束不同。
本实施例中，第一PDCCH和第二PDCCH可以指示一个PUCCH资源集合中相应索引号的PUCCH资源，也可以指示两个PUCCH资源集合中的索引号相同的PUCCH资源。例如，第一PDCCH除了指示第一PUCCH资源外，还可以指示第三PUCCH资源，第一PUCCH资源与第三PUCCH资源分别来自于两个PUCCH资源集合。同理，第二PDCCH除了指示第二PUCCH资源外还可以指示第四PUCCH资源，第二PUCCH资源与第四PUCCH资源分别来自于两个PUCCH资源集合。
可选的，本实施例中，第一PUCCH资源可以由在不同时间单元上传输的PUCCH资源组成。比如，这些PUCCH资源承载相同的UCI，即相同的PUCCH在不同的时间单元上重复发送。同理，上述第二PUCCH资源和第三PUCCH资源也可以由在不同时间单元上传输的PUCCH资源组成。
需要明确的是，本申请实施例中涉及到的第一、第二、第三、第四只是用于区分不同的数据，并不表示先后顺序关系。
步骤S102、终端设备在第一PUCCH资源上向网络设备发送第一下行TB的应答信息和第二下行TB的应答信息。
其中，TB的应答信息是指TB的HARQ反馈信息，HARQ反馈信息可以为ACK消息或NACK消息。
可选的，终端设备在第二PUCCH资源上发送第一下行TB的应答信息和/或第二下行TB的应答信息。其中，终端设备通过两个不同波束在第一PUCCH资源和第二PUCCH资源上发送TB的应答信息，例如，当网络设备通过第一波束发送第一PDCCH，通过第二波束发送第二PDCCH时，终端设备可以通过第一波束在第一PUCCH资源上向网络设备发送第一下行TB的应答信息和第二下行TB的应答信息，通过第二波束在第二PUCCH资源上向网络设备发送第一下行TB的应答信息和/或第二下行TB的应答信息。其中，第一PUCCH资源和第二PUCCH资源可以属于相同的PUCCH资源集合，也可以属于不同的PUCCH资源集合。该方式中，每个PDCCH指示一个PUCCH资源，用于TB的应答信息的反馈。
相应的，终端设备要根据第一PDCCH确定第一PUCCH资源，根据第二PDCCH确定第二PUCCH资源，终端设备可以采用现有的方法确定第一PUCCH资源和第二PUCCH资源，以第一PUCCH资源为例，终端设备先解调出第一PDCCH，根据第一PUCCH上承载的UCI的比特数来决定第一PUCCH资源所在的PUCCH资源集合，然后，根据第一PDCCH所承载的DCI中的PUCCH resource indicator域的值获取第一PUCCH资源的索引号，根据第一PUCCH资源的索引号和第一PUCCH资源所在的PUCCH资源集合(也可能还需要根据其他参数)，得到第一PUCCH资源，同理，可以得到第二PUCCH资源。
终端设备除了确定第一PUCCH资源和第二PUCCH资源外，还需要确定发送第一PUCCH资源和第二PUCCH资源的时间单元的序号。然后，终端设备根据确定的时间单元的序号，在第一PUCCH资源和第二PUCCH资源上向网络设备发送应答信息。其中，发送第一PUCCH资源的时间单元和发送第二PUCCH资源的时间单元的序号可能相同，也可能不同。终端设备可以采用现有的方案确定发送第一PUCCH资源的时间单元和发送第二PUCCH资源的时间单元的序号，也可以采用本申请实施例提供的方法，本申请实施例提供的方法如下：
以发送第一PUCCH资源的时间单元的序号为例，可选的，终端设备根据以下公式确定发送第一PUCCH资源的时间单元的序号：
n'＝n+k 1+k offset；
其中，n'为发送第一PUCCH资源的时间单元的序号，n为接收第一PDCCH的时间单元的序号，k offset为第一PUCCH资源所在PUCCH资源集合对应的偏移因子，k 1为第一时间信息，该第一时间信息可以为第一PDCCH所承载的DCI中的PDSCH的反馈时间指示域(PDSCH-to-HARQ-feedback timing indicator)的值，PDSCH的反馈时间指示域指示的是PDSCH中承载的TB的应答信息与TB的接收时间单元之间的间隔时间，该间隔时间(即k 1)为时间单元的个数。本申请实施例中，需要为每个PUCCH资源集合配置一个偏移因子，该偏移因子可以包含在PUCCH资源集合的配置信息中。
可选的，终端设备在第三PUCCH资源上发送第一下行TB的应答信息和/或第二下行TB的应答信息，第三PUCCH资源由第一PDCCH资源指示。其中，终端设备通过两个不同波束在第一PUCCH资源和第三PUCCH资源上发送TB的应答信息，例如，当网络设备通过第一波束发送第一PDCCH，通过第二波束发送第二PDCCH时，终端设备可以通过第一波束在第一PUCCH资源上向网络设备发送第一下行TB的应答信息 和第二下行TB的应答信息，通过第二波束在第三PUCCH资源上向网络设备发送第一下行TB的应答信息和/或第二下行TB的应答信息。其中，第一PUCCH资源和第三PUCCH资源的索引号相同，但是，第一PUCCH资源和第三PUCCH资源属于不同的控制资源集合。该方式中，网络设备通过一个PDCCH指示两个PUCCH资源，用于TB的应答信息的反馈。
相应的，终端设备根据第一PDCCH中承载的上行资源指示域的信息以及网络设备通过高层信令配置的两个PUCCH资源集合的配置信息，确定第一PUCCH资源和第三PUCCH资源。
可选的，网络设备需要预先通过高层信令为终端设备配置两个PUCCH资源集合，终端设备根据第一PDCCH中承载的上行资源指示域的信息以及网络设备配置的两个PUCCH资源集合的配置信息，确定第一PUCCH资源和第三PUCCH资源，具体为：根据两个PUCCH资源集合关联的控制资源集合的标识(比如CORESET-ID)对应的控制资源集合(Control Resource Set，CORESET)，从该控制资源集合中解调出第一PDCCH，该控制资源集合的标识是由网络设备通过高层信令配置的；根据第一PDCCH中承载的上行资源指示域的值，确定第一PDCCH指示的PUCCH资源的索引值；根据第一PDCCH指示的PUCCH资源的索引值，从两个PUCCH资源集合中确定第一PUCCH资源和第三PUCCH资源。
例如，网络设备配置了第一PUCCH资源集合和第二PUCCH资源集合，则终端设备根据第一PDCCH指示的PUCCH资源的索引值，从第一PUCCH资源集合中确定第一PUCCH资源，根据第一PDCCH指示的PUCCH资源的索引值，从第二PUCCH资源集合中确定第三PUCCH资源。
可选的，第一PDCCH中承载第二指示信息，其中，该第二指示信息用于指示第一PDCCH所指示的PUCCH资源(包括第一PUCCH资源和第三PUCCH资源)是否均用于反馈下行TB的应答信息。终端设备根据第一PDCCH中承载的第二指示信息，确定是否在第一PUCCH资源和第三PUCCH资源上均反馈下行TB的应答信息。当第二指示信息指示第一PDCCH所指示的PUCCH资源均用于反馈下行TB的应答信息时，终端设备使用第一PUCCH资源和第三PUCCH资源向网络设备发送下行TB的应答信息。
当然，第一PDCCH中也可以不承载第二指示信息，网络设备和终端设备预先约定好第一PDCCH所指示的PUCCH资源是否均用于反馈下行TB的应答信息，或者，网络设备通过高层信令指示终端设备第一PDCCH所指示的PUCCH资源是否均用于反馈下行TB的应答信息。
可选的，终端设备还根据第一PDCCH中承载的第一时间信息、接收第一PDCCH的时间单元的序号以及网络设备通过高层信令配置的两个PUCCH资源集合的配置信息，确定发送第一PUCCH资源和第三PUCCH资源的时间单元的序号，然后，根据时间单元的序号，在第一PUCCH资源和第三PUCCH资源上向网络设备发送应答信息。其中，该第一时间信息可以为第一PDCCH所承载的DCI中的PDSCH到反馈时间指示域的值。
可选的，终端设备根据以下公式确定发送PUCCH资源的传输单元的序号：
n'＝n+k 1+k offset；
其中，n'为发送PUCCH资源的传输单元的序号，n为接收PDCCH的传输单元的序号，k offset为偏移因子，k 1为第一时间信息。
可选的，在步骤S102之前，终端设备根据每个PDCCH对应的第一指示信息确定PDCCH所指示的PUCCH资源上所承载的应答信息，该第一指示信息用于指示该PDCCH所指示的PUCCH资源上所承载的应答信息为该PDCCH调度的下行TB的应答信息或两个PDCCH(第一PDCCH和第二PDCCH)调度的下行TB的应答信息，该第一指示信息携带在该PDCCH所承载的下行控制信息DCI中。
本申请实施例中可以在DCI中增加1比特(bit)信息域来携带第一指示信息。例如，在第一PDCCH和第二PDCCH的DCI信息域引入1比特信息域，该信息域用于承载第一指示信息，当该信息域的值为“1”时，该信息域用于指示该PDCCH所指示的PUCCH资源上承载的TB的应答信息为该PDCCH所调度的下行TB的应答信息；当该信息域的值为“0”时，该信息域用于指示该PDCCH所指示的PUCCH资源上承载的TB的应答信息为两个PDCCH(第一PDCCH和第二PDCCH)所调度的下行TB的应答信息。当然，这里只是举例，也可以通过“1”指示该PDCCH所指示的PUCCH资源上承载的TB的应答信息为两个PDCCH(第一PDCCH和第二PDCCH)所调度的下行TB的应答信息，通过“0指示”该PDCCH所指示的PUCCH资源上承载的TB的应答信息为该PDCCH所调度的下行TB的应答信息。或者，通过DCI中的多个比特位携带第一指示信息。
例如，第一PDCCH所承载的DCI中用于携带第一指示信息的信息域值为“0”，第二PDCCH所承载的DCI中用于携带第一指示信息的信息域的值为“1”，则终端设备根据第一PDCCH携带的第一指示信息，确定第一PDCCH指示的第一PUCCH资源上承载的应答信息为第一PDCCH所调度的第一下行TB的应答信息以及第二PDCCH所调度的第二下行TB的应答信息；根据第二PDCCH携带的第一指示信息，确定第二PDCCH指示的第二PUCCH资源上承载的下行TB的应答信息为第二PDCCH所调度的第二下行TB的应答信息。或者，第一PDCCH和第二PDCCH所承载的DCI中用于携带第一指示信息的信息域值为“0”，则终端设备根据第一PDCCH携带的第一指示信息，以及第二PDCCH携带的第一指示信息，确定第一PUCCH资源和第二PUCCH资源承载的TB的应答信息相同，均为第一PDCCH所调度的第一下行TB的应答信息和第二PDCCH所调度的第二下行TB的应答信息。
可选的，在步骤S102之前，终端设备根据每个PDCCH对应的第一指示信息确定该PDCCH所指示的PUCCH资源上所承载的应答信息，其中，该第一指示信息用于指示该PDCCH所属的控制资源集合中传输的PDCCH所指示的PUCCH资源上所承载的应答信息为所传输的PDCCH调度的下行TB的应答信息或两个PDCCH调度的下行TB的应答信息，该第一指示信息携带在高层信令中。该高层信令可以是已有信令，还可以是本申请实施例新引入的高层信令，例如，本申请实施例引入高层信令PUCCH-Resource-Repetition携带第一指示信息。
具体的，第一PDCCH和第二PDCCH在两个不同的控制资源集合中传输，网络设备为每个终端设备划分一个或多个控制资源集合，并在终端设备对应的任一控制资源 集合上，向终端设备发送PDCCH，控制资源集合在频域上由物理资源块(Physical Resource Block，PRB)组成，时域上由连续的OFDM符号组成，控制资源集合位于终端设备的一个下行带宽区域(Bandwidth Part，BWP)内。
网络设备在配置这两个CORESET时，引入一个高层信令，当该高层信令为“0”或“Disabled”时，在该CORESET内传输的PDCCH所指示的PUCCH资源上承载的下行TB的应答信息为该PDCCH所调度下行TB的HARQ反馈信息。当该高层信令为“1”或“Enabled”时，在该CORESET内传输的PDCCH所指示的PUCCH资源上承载的下行TB的应答信息为两个PDCCH所调度的两个下行TB的应答信息。这里只是举例说明，也可以通过“0”或“Disabled”指示PDCCH所指示的PUCCH资源上承载的下行TB的应答信息为两个PDCCH所调度的两个下行TB的应答信息，通过“1”或“Enabled”指示PDCCH所指示的PUCCH资源上承载的下行TB的应答信息为该PDCCH所调度下行TB的HARQ反馈信息。或者，该高层信令为多个比特位。
本实施例中，如果终端设备接收到第一指示信息，则根据第一指示信息确定每个PUCCH资源上承载的下行TB的应答信息。如果终端设备没有接收到第一指示信息，则终端设备可以自行决定每个PUCCH资源上承载的应答信息，只要满足至少一个PUCCH资源上承载了两个PDCCH调度的TB的应答信息即可。
网络设备接收到第一PUCCH资源和第二PUCCH资源上承载的下行TB的应答信息后，对两个PUCCH资源上承载的应答信息进行合并处理，同时获得分集增益和合并增益，提高PUCCH传输的可靠性和覆盖范围。同时当一个天线Panel的上行波束失效时，基站仍可以从另一个天线Panel上获得两个TB的HARQ反馈信息，从而保证能够基站接收到TB的HARQ反馈信息。
本实施例中，终端设备接收网络设备发送的第一PDCCH和第二PDCCH，第一PDCCH和第二PDCCH在同一时间单元内传输，第一PDCCH指示第一PUCCH资源且用于调度第一下行TB，第二PDCCH指示第二PUCCH资源且用于调度第二下行TB，终端设备在第一PUCCH资源上向网络设备发送第一下行TB的应答信息和第二下行TB的应答信息。当一个PUCCH接收失败时，网络设备可以从另一个PUCCH上获取到两个下行TB的应答信息，从而能够保证下行TB的HARQ反馈信息正确接收。
在实施例一的基础上，图3为本申请实施例二提供的上行控制信息的发送方法的信令流程图，本实施例中网络设备通过一个PDCCH指示两个PUCCH资源，如图3所示，本实施例提供的方法包括以下步骤：
步骤S201、网络设备向终端设备发送配置信息，该配置信息用于配置终端设备在同一时间单元内接收两个PDCCH。
步骤S202、网络设备为终端设备配置第一PUCCH资源集合和第二PUCCH资源集合，以及第一PUCCH资源集合和第二PUCCH资源集合关联的控制资源集合的标识。
其中，两个PUCCH资源集合关联一个控制资源集合，网络设备通过高层信令配置第一PUCCH资源集合、第二PUCCH资源集合以及第一PUCCH资源集合和第二PUCCH资源集合关联的控制资源集合的标识。第一PUCCH资源集合的配置信息中包括第一偏移因子，第二PUCCH资源集合的配置信息中包括第二偏移因子。
步骤S203、网络设备在同一时间单元内向终端设备发送第一PDCCH、第二PDCCH、第一PDCCH所调度的第一下行TB和第二PDCCH所调度的第二下行TB。
其中，第一PDCCH和第二PDCCH通过不同的波束发送，第一PDCCH在第一PUCCH资源集合和第二PUCCH资源集合关联的控制资源集合中传输，第二PDCCH在其他控制资源集合中传输。当然，也可以将第二PDCCH在第一PUCCH资源集合和第二PUCCH资源集合关联的控制资源集合中传输，第一PDCCH在其他控制资源集合中传输。第一PDCCH指示第一PUCCH资源和第三PUCCH资源，第二PDCCH不指示PUCCH资源或指示第二PUCCH资源。
本实施例中，第一PDCCH所承载的DCI中携带有第一指示信息，该第一指示信息用于指示第一PUCCH资源和第三PUCCH资源上所承载的TB的应答信息为第一下行TB和第二下行TB的应答信息。

步骤S207、终端设备在第一PUCCH资源和第三PUCCH资源上向网络设备发送第一下行TB和第二下行TB的应答信息。
本实施例中，网络设备在第一PDCCH中指示了终端设备在第一PUCCH资源和第三PUCCH资源上反馈两个PDCCH所调度的下行的TB的应答信息，因此，终端设备根据在第一PUCCH资源和第三PUCCH资源上向网络设备发送第一下行TB和第二下行TB的应答信息。
步骤S208、网络设备对第一PUCCH资源和第三PUCCH资源接收到的TB的应答信息进行合并。
在实施例一的基础上，图4为本申请实施例三提供的上行控制信息的发送方法的信令流程图，本实施例中网络设备通过一个PDCCH指示两个PUCCH资源，如图4所示，本实施例提供的方法包括以下步骤：
步骤S301、网络设备向终端设备发送配置信息，该配置信息用于配置终端设备在同一时间单元内接收两个PDCCH。
步骤S302、网络设备为终端设备配置第一PUCCH资源集合和第二PUCCH资源集合。
网络设备同时通过高层信令配置每个PUCCH资源集合所关联的控制资源集合的标识，在控制资源集合的标识所对应的控制资源集合中传输的PDCCH所指示的PUCCH资源属于所关联的PUCCH资源集合。
其中，网络设备通过高层信令配置第一PUCCH资源集合和第二PUCCH资源集合。第一PUCCH资源集合的配置信息中包括第一偏移因子，第二PUCCH资源集合的配置信息中包括第二偏移因子。
步骤S303、网络设备在同一时间单元内向终端设备发送第一PDCCH、第二PDCCH、第一PDCCH所调度的第一下行TB和第二PDCCH所调度的第二下行TB。
其中，第一PDCCH和第二PDCCH通过不同的波束发送，第一PDCCH和第二PDCCH在不同的控制资源集合中传输。第一PDCCH指示第一PUCCH资源，第二PDCCH指示第二PUCCH资源
本实施例中，第一PDCCH所承载的DCI中携带有第一指示信息，该第一指示信息用于指示第一PUCCH资源上所承载的TB的应答信息为第一下行TB和第二下行TB的应答信息。第二PDCCH所承载的DCI中携带有第一指示信息，该第一指示信息用于指示第二PUCCH资源上所承载的下行TB的应答信息为第二下行TB的应答信息。
步骤S304、终端设备根据第一PDCCH中承载的上行资源指示域的值，确定第一PDCCH指示的PUCCH资源的索引值，根据第二PDCCH中承载的上行资源指示域的值，确定第二PDCCH指示的PUCCH资源的索引值。
同时，终端设备从第一PDCCH和第二PDCCH所承载的DCI的PDSCH到反馈时间指示域的值k 1。
步骤S305、终端设备根据第一PDCCH指示的PUCCH资源的索引值，从第一PUCCH资源集合中确定第一PUCCH资源，根据第二PDCCH指示的PUCCH资源的索引值，从第二PUCCH资源集合中确定第二PUCCH资源。
步骤S306、终端设备确定发送第一PUCCH资源的第一时间单元的序号，以及发送第二PUCCH资源的第二时间单元的序号。
终端设备从第一PUCCH资源集合中获取第一偏移因子，从第二PUCCH资源集合中获取第二偏移，根据公式n'＝n+k 1+k offset计算第一PUCCH资源和第二PUCCH资源的时间单元的序号。
步骤S307、终端设备在第一PUCCH资源上向网络设备发送第一下行TB和第二下行TB的应答信息，在第二PUCCH资源上向网络设备发送第二下行TB的应答信息。
本实施例中，网络设备在第一PDCCH中指示了第一PUCCH资源上反馈两个PDCCH所调度的下行的TB的应答信息，因此，终端设备在第一PUCCH资源上向网络设备发送第一下行TB和第二下行TB的应答信息。由于网络设备在第二PDCCH中指示了第二PUCCH资源上反馈第二PDCCH所调度的下行TB的应答信息，因此，终端设备在第二PUCCH资源上向网络设备发送第二下行TB的应答信息。
步骤S308、网络设备对第一PUCCH资源和第三PUCCH资源接收到的TB的应答信息进行合并。
上述实施例中以网络设备在同一时间单元内向终端设备发送两个PDCCH为例，当然，本实施例的方法也不限于两个PDCCH，网络设备可以在同一时间单元内向终端 设备发送更多的PDCCH，例如，网络设备在同一时间单元内向终端设备同时发送3个PDCCH或4个PDCCH，多个PDCCH通过不同的波束发送。相应的，终端设备也可以在每个PUCCH资源上向网络设备发送更多的PDCCH所调度的下行TB的应答信息，例如，终端设备在每个PUCCH上向网络设备发送3个PDCCH所调度的下行TB的应答信息，或者，在每个PUCCH上向网络设备发送4个PDCCH所调度的下行TB的应答信息。多个(大于两个)PDCCH的实现方式与上述两个PDCCH的方式类似，这里不再赘述。
