本申请主张在2018年6月21日在中国提交的中国专利申请号No.201810643473.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信领域，尤其涉及一种上行控制信息发送方法、终端设备和网络侧设备。
背景技术
在第五代(Fifth Generation,5G)移动通信系统新空口(New Radio，NR)中，非授权频段(un-licensed band)可以作为授权频段(licensed band)的补充，以帮助运营商对服务进行扩容。由于非授权频段由多种技术共用，例如，无线保真(Wireless-Fidelity,WiFi)，雷达，长期演进-授权辅助接入(Long-Term Evolution-License Assisted Access，LTE-LAA)等。因此，在使用非授权频段时需要符合先听后说(listen before talk，LTB)规则，即发送数据之前先进行信道侦听，只有在侦听结果为信道空闲时才可以进行数据发送，以保证所有设备可以公平的使用非授权频段资源。
终端设备(User Equipment，UE)在向基站反馈上行控制信息(Uplink Control Information，UCI)时，若信道侦听的侦听结果为信道忙，则UE无法及时发送UCI，使得基站需要对之前的调度进行数据重传，使得资源利用率较低。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
参见图1，图1为本公开实施例提供的一种网络架构示意图。如图1所示，包括用户终端11和基站12，其中，用户终端11可以是终端设备(User  Equipment，UE)，例如：可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等终端侧设备，需要说明的是，在本公开实施例中并不限定用户终端11的具体类型。上述基站12可以是5G及以后版本的基站(例如：gNB、5G NR NB)，或者其他通信系统中的基站，或者称之为节点B，需要说明的是，在本公开实施例中仅以5G基站为例，但是并不限定基站12的具体类型。
需要说明的是，上述用户终端11和基站12的具体功能将通过以下多个实施例进行具体描述。
图2为本公开实施例提供的上行控制信息发送方法的流程示意图。所述方法应用于终端设备，所述方法可以如下所示。
步骤S210，从网络侧设备接收下行控制信息(Downlink Control Information，DCI)，其中，该DCI用于指示终端设备反馈历史下行传输对应的UCI，其中，历史下行传输对应的UCI未反馈或反馈失败。
步骤S220，发送未反馈或反馈失败的历史下行传输对应的UCI给所述网络侧设备。
针对于历史下行传输，终端设备在反馈该历史下行传输对应的UCI之前，需要先进行信道侦听，若信道侦听结果为信道忙，则该历史下行传输对应的UCI无法反馈或反馈失败。
为了使得未反馈或反馈失败的历史下行传输对应的UCI能够及时向网络侧设备反馈，接收用于指示终端设备反馈历史下行传输对应的UCI的DCI，进而终端设备发送该未反馈或反馈失败的历史下行传输对应的UCI，使得网络侧设备及时接收到反馈。
根据需要反馈的UCI的不同，下面详细介绍UCI的发送过程。
第一种：UCI为PDSCH对应的ACK/NACK。
本公开实施例中，DCI用于调度第一物理下行共享信道(Physical Downlink Shared Channel，PDSCH)组，其中，第一PDSCH组是与第一物理上行控制信道(Physical Uplink Control Channel，PUCCH)关联的PDSCH集合；历史下行传输为第二PDSCH组，其中，第二PDSCH组是与第二PUCCH 关联的PDSCH集合，第二PUCCH的发送时刻早于第一PUCCH的发送时刻；UCI为第二PDSCH组对应的确认应答信息(Acknowledgement，ACK)/否定应答信息(Negative Acknowledgement，NACK)。
图3为本公开实施例提供的PDSCH调度示意图。
如图3所示，网络侧设备配置2组PDSCH，即在一个PUCCH资源上最多反馈2组PDSCH的ACK/NACK信息。PDSCH组1是与PUCCH1关联的PDSCH集合，PDSCH组1包括三个PDSCH；PDSCH组2是与PUCCH2关联的PDSCH集合，PDSCH组2包括三个PDSCH。
网络侧设备依次调度PDSCH组2和PDSCH组1。
网络侧设备调度下行传输PDSCH组2时，终端设备需要在PUCCH2的发送时刻反馈PDSCH组2对应的ACK/NACK。
但是，若终端设备在PUCCH2的发送时刻的信道侦听结果为信道忙，则PDSCH组2对应的ACK/NACK无法反馈。此时，PDSCH组2成为历史下行传输第二PDSCH组，PUCCH2成为与历史下行传输第二PDSCH组(PDSCH组2)关联的第二PUCCH，未反馈的PDSCH组2对应的ACK/NACK成为历史下行传输第二PDSCH组(PDSCH组2)对应的UCI。
为了及时反馈历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK，网络侧设备调度下行传输PDSCH组1时，即PDSCH组1成为当前下行传输第一PDSCH组，PUCCH1成为与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH。终端设备接收调度当前下行传输第一PDSCH组(PDSCH组1)的DCI，其中，该DCI用于指示终端设备反馈之前未反馈或反馈失败的历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK。
进而终端设备在与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH(PUCCH1)上，发送历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK和当前下行传输第一PDSCH组(PDSCH组1)对应的ACK/NACK。
本公开实施例中，是否发送历史下行传输对应的ACK/NACK可以通过显示指示或隐示指示的方式来配置，下面分别详细介绍。
A：显示指示。
本公开实施例中，发送历史下行传输对应的UCI，包括：
若DCI中包括第二PDSCH组的混合自动重传请求确认信息(Hybrid ARQ,Hybrid Automatic Repeat Request，HARQ-ACK)指示域，则在第一PUCCH上，发送第二PDSCH组对应的ACK/NACK和第一PDSCH组对应的ACK/NACK。
在调度当前下行传输第一PDSCH组的DCI中，增加历史下行传输第二PDSCH组的HARQ-ACK指示域。
终端设备接收到该调度当前下行传输第一PDSCH组的DCI之后，若该DCI中包括的历史下行传输第二PDSCH组的HARQ-ACK指示域为激活状态，则终端设备在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传；
若该DCI中包括的历史下行传输第二PDSCH组的HARQ-ACK指示域为未激活状态，则终端设备在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK。
不同PDSCH组对应的ACK/NACK可以进行联合编码或独立编码之后进行发送。
本公开实施例中，第二PDSCH组中包括至少一个PDSCH组；DCI中包括多个HARQ-ACK指示域，不同HARQ-ACK指示域对应于第二PDSCH组中不同的PDSCH组。
若历史下行传输第二PDSCH组中存在多个ACK/NACK未反馈或反馈失败的PDSCH组，则在调度当前下行传输第一PDSCH组的DCI中可以包含历史下行传输第二PDSCH组中每个PDSCH组的HARQ-ACK指示域。
网络侧设备配置PDSCH组的组标识ID，使得在调度当前下行传输第一PDSCH组的DCI中，增加组ID计数域，其中，组ID计数域用于指示当前调度的是哪组PDSCH，以及辅助历史下行传输第二PDSCH组的HARQ-ACK指示域来确定反馈历史下行传输第二PDSCH组中哪个PDSCH组对应的ACK/NACK。
图4为本公开实施例提供的PDSCH调度的另一种示意图。
如图4所示，网络侧设备配置3组PDSCH，即在一个PUCCH资源上最多反馈3组PDSCH的ACK/NACK信息。PDSCH组3是与PUCCH3关联的PDSCH集合，PDSCH组3包括三个PDSCH；PDSCH组2是与PUCCH2关联的PDSCH集合，PDSCH组2包括三个PDSCH；PDSCH组1是与PUCCH1关联的PDSCH集合，PDSCH组1包括三个PDSCH。
由于网络侧设备配置了3组PDSCH，则组ID计数域的比特数为2比特(bit),调度PDSCH的DCI中的HARQ-ACK反馈指示域的比特数为3bit。
网络侧依次调度PDSCH组3、PDSCH组2和PDSCH组1。
网路侧设备调度下行传输PDSCH组3时，即PDSCH组3成为当前下行传输第一PDSCH组，PUCCH3成为与当前下行传输第一PDSCH组(PDSCH组3)关联的第一PUCCH。
此时，调度当前下行传输第一PDSCH组(PDSCH组3)的DCI中组ID计数域为00。若该DCI中的HARQ-ACK反馈指示域为000或100，则在与当前下行传输第一PDSCH组(PDSCH组3)关联的第一PUCCH(PUCCH3)上，发送当前下行传输第一PDSCH组(PDSCH组3)对应的ACK/NACK。
网络侧设备调度下行传输PDSCH组2时，即PDSCH组2成为当前下行传输第一PDSCH组、PUCCH2成为与当前下行传输第一PDSCH组(PDSCH组2)关联的第一PUCCH、PDSCH组3成为历史下行传输第二PDSCH组，PUCCH3成为与历史下行传输第二PDSCH组(PDSCH组3)关联的第二PUCCH。
此时，调度当前下行传输第一PDSCH组(PDSCH组2)的DCI中组ID计数域为01。若该DCI中的HARQ-ACK反馈指示域为000或010，则在与当前下行传输第一PDSCH组(PDSCH组2)关联的第一PUCCH(PUCCH2)上，发送当前下行传输第一PDSCH组(PDSCH组2)对应的ACK/NACK；
若该DCI中的HARQ-ACK反馈指示域为100或110，则在与当前下行传输第一PDSCH组(PDSCH组2)关联的第一PUCCH(PUCCH2)上，发送历史下行传输第二PDSCH组(PDSCH组3)对应的ACK/NACK和当前下行传输第一PDSCH组(PDSCH组2)对应的ACK/NACK。
网络侧设备调度下行传输PDSCH组1时，即PDSCH组1成为当前下行传输第一PDSCH组、PUCCH1成为与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH、PDSCH组3和PDSCH组2成为历史下行传输第二PDSCH组、PUCCH3和PUCCH2成为与历史下行传输第二PDSCH组(PDSCH组3和PDSCH组2)关联的第二PUCCH。
此时，调度当前下行传输第一PDSCH组(PDSCH组3)的DCI中组ID计数域为10。
若该DCI中的HARQ-ACK反馈指示域为000或001，则在与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH(PUCCH1)上，发送当前下行传输第一PDSCH组(PDSCH组1)对应的ACK/NACK；
若该DCI中的HARQ-ACK反馈指示域为010或011，则在与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH(PUCCH1)上，发送历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK和当前下行传输第一PDSCH组(PDSCH组1)对应的ACK/NACK；
若该调度DCI中的HARQ-ACK指示域为110或111，则在与当前下行传输第一PDSCH组(PDSCH组1)关联的第一PUCCH(PUCCH1)上，发送历史下行传输第二PDSCH组(PDSCH组3和PDSCH组2)对应的ACK/NACK和当前下行传输第一PDSCH组(PDSCH组1)对应的ACK/NACK。
网络侧设备还可以在调度下行传输PDSCH组的DCI中增加DAI总数标识，用于指示当前调度的下行传输PDSCH组中包括的PDSCH的总个数。
B：隐示指示。
本公开实施例中，发送历史下行传输对应的UCI，包括：
若DCI对应的预设信息符合预设发送规则，则在第一PUCCH上，发送第二PDSCH组对应的ACK/NACK和第一PDSCH组对应的ACK/NACK。
网络侧设备确定发送历史下行传输对应的ACK/NACK的预设发送规则，并通过高层信令向终端设备配置该预设发送规则，使得当终端设备接收到调度当前下行传输第一PDSCH组的DCI时，若该DCI对应的预设信息符合预设发送规则，则终端设备在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行 传输第一PDSCH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传。
隐示指示方式可以包括下述几种。
(1)承载DCI的物理下行控制信道(Physical Downlink Control Channel，PDCCH)对应的CORESET为目标CORESET。
例如，根据承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的CORESET来确定预设发送规则。
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的CORESET ID为偶数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的CORESET ID为奇数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
其中，历史下行传输第二PDSCH组中包括的需要反馈ACK/NACK的PDSCH组的个数由网络配置，例如，1，2，3，4等值。
(2)承载DCI的PDCCH对应的search space为目标search space。
例如，根据承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的search space来确定预设发送规则。
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的search space ID为偶数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的search space ID为奇数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
其中，历史下行传输第二PDSCH组中包括的需要反馈ACK/NACK的PDSCH组的个数由网络配置，例如，1，2，3，4等值。
(3)承载DCI的PDCCH对应的控制信息单元(Control Channel Element， CCE)为目标CCE。
例如，根据承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的CCE来确定预设发送规则。
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的起始CCE ID为偶数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若承载调度当前下行传输第一PDSCH组的DCI的PDCCH所对应的起始CCE ID为奇数，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
其中，历史下行传输第二PDSCH组中包括的需要反馈ACK/NACK的PDSCH组的个数由网络配置，例如，1，2，3，4等值。
(4)DCI中的ACK/NACK资源索引(ACK/NACK Resource Indexes，ARI)为目标ARI。
例如，根据调度当前下行传输第一PDSCH组的DCI中的ARI来确定预设发送规则。
若调度当前下行传输第一PDSCH组的DCI中的ARI使用配置ARI资源总数的后半部分，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若调度当前下行传输第一PDSCH组的DCI中的ARI使用配置ARI资源总数的前半部分，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
其中，历史下行传输第二PDSCH组中包括的需要反馈ACK/NACK的PDSCH组的个数由网络配置，例如，1，2，3，4等值。
(5)DCI中的传输功率控制(Transmit Power Control，TPC)为目标TPC。
例如，根据调度当前下行传输第一PDSCH组的DCI中的TPC来确定预设发送规则。
例如，若调度当前下行传输第一PDSCH组的DCI中的TPC指示1或3， 则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若调度当前下行传输第一PDSCH组的DCI中的TPC指示0或2，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
其中，历史下行传输第二PDSCH组中包括的需要反馈ACK/NACK的PDSCH组的个数由网络配置，例如，1，2，3，4等值。
(6)DCI中的循环冗余校验(Cyclic Redundancy Check，CRC)为目标CRC。
相关技术中，DCI中的CRC长度为24bit，终端设备的无线电网络临时编码(Radio Network Temporary Identity，RNTI)加扰其中16位bit，其余还有8bit可以使用。本公开实施例中，设计一个8bit的序列，例如，ZC序列、walsh序列等加扰该8bit CRC，辅助指示是否反馈历史下行传输对应的ACK/NACK。
例如，若调度当前下行传输第一PDSCH组的DCI中CRC对应的扰码为[1 1 1 1 1 1 1 1]，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK；
若调度当前下行传输第一PDSCH组的DCI中CRC对应的扰码为[1 1 -1 -1 1 1 -1 -1]，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK和最近一个历史下行传输第二PDSCH组对应的ACK/NACK；
若调度当前下行传输第一PDSCH组的DCI中CRC对应的扰码为[1 1 1 1 -1 -1 -1 -1]，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK和最近两个历史下行传输第二PDSCH组对应的ACK/NACK；
若调度当前下行传输第一PDSCH组的DCI中CRC对应的扰码为[1 -1 -1 1 -1 1 1 -1]，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送当前下行传输第一PDSCH组对应的ACK/NACK和最近三个历史下行传输 第二PDSCH组对应的ACK/NACK。
本公开实施例中，在第一PUCCH上，发送第二PDSCH组对应的ACK/NACK和第一PDSCH组对应的ACK/NACK，包括：若第二PDSCH组对应的ACK/NACK的比特数大于预设比特数，则根据预设比特数，对第二PDSCH组对应的ACK/NACK进行比特数绑定，得到第二PDSCH组对应的绑定后ACK/NACK，其中，预设比特数表示第二PDSCH组对应的ACK/NACK的最大传输比特数；在第一PUCCH上，发送第二PDSCH组对应的绑定后ACK/NACK和第一PDSCH组对应的ACK/NACK。
当在一个PUCCH上反馈多个PDSCH组对应的ACK/NACK时，若按照半静态码本进行反馈，即根据可能接收到的PDSCH的数量反馈ACK/NACK，反馈效率低；若按照动态码本进行反馈，即根据实际接收到的PDSCH的数量反馈ACK/NACK，那么当最后一个PDSCH的调度授权丢失时，会引起ACK/NACK载荷大小的混淆，使得网络侧设备对接收到的ACK/NACK解码失败。
为了可以避免ACK/NACK载荷大小的混淆，若在当前下行传输第一PDSCH组关联的第一PUCCH上发送一个或多个PDSCH组对应的ACK/NACK时，对每个PDSCH组对应的ACK/NACK的最大传输比特数进行配置。
图5为本公开实施例提供的比特数绑定的示意图。
在图5中，历史下行传输第二PDSCH组(PDSCH组3和PDSCH组2)中，PDSCH组3包括6个PDSCH：DAI＝1-6对应的PDSCH，PDSCH组2包括6个PDSCH：DAI＝1-6对应的PDSCH。
网络侧设备配置预设比特数4bit，即历史下行传输第二PDSCH组(PDSCH组3和PDSCH组2)中每个PDSCH组对应的ACK/NACK的最大传输比特数为4bit。
由于历史下行传输第二PDSCH组(PDSCH组3)中包括6个PDSCH，若不进行比特数绑定，历史下行传输第二PDSCH组(PDSCH组3)对应的ACK/NACK的比特数至少为6bit，大于预设比特数4bit。因此，对历史下行传输第二PDSCH组(PDSCH组3)对应的ACK/NACK进行比特数绑定：对 于DAI＝1-3的PDSCH，分别对应1bit的ACK/NACK；对于DAI＝4-6的PDSCH，一共对应1bit的ACK/NACK。此时，历史下行传输第二PDSCH组(PDSCH组3)对应的ACK/NACK的比特数为4bit。
由于历史下行传输第二PDSCH组(PDSCH组2)中包括6个PDSCH，若不进行比特数绑定，历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK的比特数至少为6bit，大于预设比特数4bit。因此，对历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK进行比特数绑定：对于DAI＝1-3的PDSCH，分别对应1bit的ACK/NACK；对于DAI＝4-6的PDSCH，一共对应1bit的ACK/NACK。此时，历史下行传输第二PDSCH组(PDSCH组2)对应的ACK/NACK的比特数为4bit。
通过进行比特数绑定，使得历史下行传输第二PDSCH组中每个PDSCH组对应的ACK/NACK载荷是一个确定的比特数，不会由于授权丢失导致载荷大小的混淆。
此外，针对图5所示绑定操作得到的1bit ACK/NACK对应的PDSCH，即DAI＝4-6的PDSCH，网络侧设备可以限制调度的PDSCH的数量，例如，只调度DAI＝4的1个PDSCH，以解决潜在的授权丢失情况。
需要说明的是，若历史下行传输第二PDSCH组中某一个PDSCH组对应的ACK/NACK的比特数小于预设比特数，则在该PDSCH组对应的ACK/NACK中增加NACK以使得达到预设比特数。
通过配置调度当前下行传输第一PDSCH组的DCI，使得该DCI用于指示终端设备反馈历史下行传输第二PDCSH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传，有效提高了资源利用率。
第二种：UCI为非周期信道状态信息(CSI，Channel State Information)报告。
本公开实施例中，历史下行传输用于触发终端设备在第一预设发送时刻反馈目标非周期CSI报告；
UCI为未反馈或反馈失败的目标非周期CSI报告；
其中，第一预设发送时刻早于DCI的接收时刻。
网络侧设备为终端设备发送参考信号(Reference Symbol，RS)，使得终端设备根据该RS计算目标非周期CSI报告，并在第一预设发送时刻反馈该目标非周期CSI报告。
但是，若在第一预设发送时刻，终端设备的信道侦听结果为信道忙，则无法反馈该目标非周期CSI报告。此时，该目标非周期CSI报告成为历史下行传输对应的目标非周期CSI报告。
为了及时反馈历史下行传输对应的目标非周期CSI报告，网络侧设备配置用于指示反馈历史下行传输对应的目标非周期CSI报告的DCI，使得终端设备接收到当前DCI之后，发送该历史下行传输对应的目标非周期CSI报告。
本公开实施例中，发送UCI，包括：
若DCI中包括触发目标非周期CSI报告上报的指示域，则在DCI指示的第二预设发送时刻发送目标非周期CSI报告。
网络侧设备在当前DCI中配置未反馈或反馈失败的目标非周期CSI报告上报的指示域，使得终端设备在接收到当前DCI之后，在DCI指示的第二预设发送时刻发送该目标非周期CSI报告，而无需网络侧设备重新发送RS，终端设备也无需重新计算非周期CSI报告，即上报历史CSI报告。
由于终端设备无需重新计算非周期CSI报告，当前DCI与第二预设发送时刻之间的时间间隔可以小于触发终端设备在第一预设发送时刻发送目标非周期CSI报告的历史DCI与第一预设发送时刻之间的时间间隔。
本公开实施例中，发送目标非周期CSI报告，包括：
若第一预设发送时刻与DCI的接收时刻之间的时间差不大于预设有效时长，或，第二预设发送时刻与第一预设发送时刻之间的时间差不大于预设有效时长，则发送目标非周期CSI报告。
网络侧设备可以通过高层信令为终端设备配置一个预设有效时长，即CSI报告有效窗，用以表示终端设备根据一个RS计算得到目标非周期CSI报告未反馈或反馈失败之后，该目标非周期CSI报告的有效时长。
接收到用于指示反馈之前未反馈或反馈失败的目标非周期CSI报告的当前DCI之后，根据该未反馈或反馈失败的目标非周期CSI报告的第一预设发送时刻和该当前DCI的接收时刻之间的时间差，或者，根据第一预设发送时 刻与当前DCI指示的第二预设发送时刻之间的时间差，判断该未反馈或反馈失败的目标非周期CSI报告是否有效。
若时间差不大于预设有效时长，即该未反馈或反馈失败的目标非周期CSI报告有效，则终端设备在第二预设发送时刻发送该未反馈或反馈失败的目标非周期CSI报告；
若时间差大于预设有效时长，即该未反馈或反馈失败的目标非周期CSI报告失效，则终端设备在第二预设发送时刻发送预设值，例如，超出范围(Out of Range，OOR)。
通过配置当前DCI用于指示终端设备反馈之前未反馈或反馈失败的目标非周期CSI报告，可以避免由于网络侧设备接收不到该未反馈或反馈失败的目标非周期CSI报告而重新发送RS，有效提高了资源利用率。
终端设备也无需重新根据RS计算非周期CSI报告，有利于节能。同时当前DCI的接收时刻与第二预设发送时刻可以采用较小的时间间隔，以达到快速上报的目的。
本公开实施例记载的技术方案，通过接收用于指示终端设备反馈历史下行传输对应的UCI的DCI，其中，该历史下行传输对应的UCI未反馈或反馈失败，使得终端设备及时发送该未反馈或反馈失败的UCI，可以避免网络侧设备进行数据重传，有效提高了资源利用率。
图6为本公开实施例提供的上行控制信息发送方法的另一流程示意图。所述方法应用于网络侧设备，所述方法可以如下所示。
步骤S610，发送DCI，其中，DCI用于指示终端设备反馈历史下行传输对应的UCI，其中，历史下行传输对应的UCI未反馈或反馈失败。
针对于历史下行传输，终端设备在反馈该历史下行传输对应的UCI之前，需要先进行信道侦听，若信道侦听结果为信道忙，则该历史下行传输对应的UCI无法反馈或反馈失败。
为了使得未反馈或反馈失败的历史下行传输对应的UCI能够及时向网络侧设备反馈，网络侧设备发送用于指示终端设备反馈历史下行传输对应的UCI的DCI，进而使得终端设备在接收到该DCI之后，反馈之前未反馈或反馈失败的历史下行传输对应的UCI，使得网络侧设备及时接收到反馈。
根据需要反馈的UCI的不同，网络侧设备发送的DCI不同。
第一种：UCI为PDSCH对应的ACK/NACK。
本公开实施例中，DCI用于调度第一PDSCH组，其中，第一PDSCH组是与第一PUCCH关联的PDSCH集合；历史下行传输为第二PDSCH组，其中，第二PDSCH组是与第二PUCCH关联的PDSCH集合，第二PUCCH的发送时刻早于第一PUCCH的发送时刻；UCI为第二PDSCH组对应的ACK/NACK。
为了及时反馈历史下行传输第二PDSCH组对应的ACK/NACK，网络侧设备调度下行传输第一PDSCH组时，即第一PDSCH组为当前下行传输，网络侧设备发送调度当前下行传输第一PDSCH组的DCI，其中，该DCI用于指示终端设备反馈之前未反馈或反馈失败的历史下行传输第二PDSCH组对应的ACK/NACK，使得终端设备在与当前下行传输第一PDSCH组关联的第一PUCCH上，反馈历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
本公开实施例中，网络侧设备发送的当前DCI是否指示终端设备发送历史下行传输对应的ACK/NACK可以通过显示指示或隐示指示的方式来配置，下面分别详细介绍。
A、显示指示。
本公开实施例中，DCI中包括第二PDSCH组的HARQ-ACK指示域，其中，第二PDSCH组的HARQ-ACK指示域用于指示终端设备在第一PUCCH上，发送第二PDSCH组对应的ACK/NACK。
网络侧设备发送的调度当前下行传输第一PDSCH组的DCI中，增加历史下行传输第二PDSCH组的HARQ-ACK指示域，使得终端设备接收到该DCI之后，若该DCI中包括的历史下行传输第二PDSCH组的HARQ-ACK指示域为激活状态，则在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传。
本公开实施例中，第二PDSCH组中包括至少一个PDSCH组；DCI中包 括多个HARQ-ACK指示域，不同HARQ-ACK指示域对应于第二PDSCH组中不同的PDSCH组。
若历史下行传输第二PDSCH组存在多个ACK/NACK未反馈或反馈失败的PDSCH组，则网络侧设备发送的调度当前下行传输第一PDSCH组的DCI中，可以包含历史下行传输第二PDSCH组中每个PDSCH组的HARQ-ACK指示域。
网络侧设备可以在发送的调度当前下行传输第一PDSCH组的DCI中，增加组ID计数域，其中，组ID计数域用于指示当前调度的是哪组PDSCH，以及辅助历史下行传输第二PDSCH组的HARQ-ACK指示域来确定反馈历史下行传输第二PDSCH组中哪个PDSCH组对应的ACK/NACK。
B：隐示指示。
本公开实施例中，DCI对应的预设信息符合预设发送规则。
网络侧设备确定反馈历史下行传输对应的ACK/NACK的预设发送规则，并通过高层信令向终端设备配置该预设发送规则。网络侧设备发送的调度当前下行传输第一PDSCH组的DCI对应的预设信息符合预设发送规则，终端设备接收到该DCI后，在与当前下行传输第一PDSCH组关联的第一PUCCH上发送历史下行传输第二PDSCH组对应的ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传。
隐示指示方式可以包括下述几种。
(1)承载DCI的PDCCH对应的CORESET为目标CORESET；
(2)承载DCI的PDCCH对应的search space为目标search space；
(3)承载DCI的PDCCH对应的CCE为目标CCE；
(4)DCI中的ARI为目标ARI；
(5)DCI中的TPC为目标TPC；
(6)DCI中的CRC为目标CRC。
本公开实施例中，所述上行控制信息发送方法还包括：通过高层信令为终端设备配置预设比特数，其中，预设比特数用于指示若第二PDSCH组对应的ACK/NACK的比特数大于预设比特数，则终端设备根据预设比特数，对第 二PDSCH组对应的ACK/NACK进行比特数绑定，得到第二PDSCH组对应的绑定后ACK/NACK，以及在第一PUCCH上，发送第二PDSCH组对应的绑定后ACK/NACK和第一PDSCH组对应的ACK/NACK；预设比特数表示第二PDSCH组对应的ACK/NACK的最大传输比特数。
当在一个PUCCH上反馈多个PDSCH组对应的ACK/NACK时，若按照半静态码本进行反馈，即根据可能接收到的PDSCH的数量反馈ACK/NACK，反馈效率低；若按照动态码本进行反馈，即根据实际接收到的PDSCH的数量反馈ACK/NACK，那么当最后一个PDSCH的调度授权丢失时，会引起ACK/NACK载荷大小的混淆，使得网络侧设备对接收到的ACK/NACK解码失败。
为了避免ACK/NACK载荷大小的混淆，网络侧设备通过高层信令为终端设备配置预设比特数，即历史下行传输第二PDSCH组中每个PDSCH组对应的ACK/NACK的最大传输比特数，使得终端设备根据该预设比特数，对历史下行传输第二PDSCH组中每个PDSCH组对应的ACK/NACK进行比特数绑定，得到第二PDSCH组对应的绑定后ACK/NACK，以及在第一PUCCH上，发送历史下行传输第二PDSCH组对应的绑定后ACK/NACK和当前下行传输第一PDSCH组对应的ACK/NACK。
通过设置预设比特数，使得历史下行传输第二PDSCH组中每个PDSCH组对应的ACK/NACK载荷是一个确定的比特数，不会由于授权丢失导致载荷大小的混淆。
通过发送调度当前下行传输第一PDSCH组的DCI，该DCI用于指示终端设备反馈历史下行传输第二PDCSH组对应的ACK/NACK，可以避免由于网络侧设备接收不到历史下行传输第二PDSCH组对应的ACK/NACK而进行数据重传，有效提高了资源利用率。
第二种：UCI为非周期CSI报告。
历史下行传输用于触发终端设备在第一预设发送时刻反馈目标非周期CSI报告；UCI为未反馈或反馈失败的目标非周期CSI报告；其中，第一预设发送时刻早于DCI的接收时刻。
网络侧设备为终端设备配置参考信号(Reference Symbol，RS)，使得终 端设备根据该RS计算目标非周期CSI报告，并在第一预设发送时刻反馈该目标非周期CSI报告。
但是，若在第一预设发送时刻，终端设备的信道侦听结果为信道忙，则无法反馈该目标非周期CSI报告。此时，该目标非周期CSI报告成为历史下行传输对应的目标非周期CSI报告。
为了及时反馈历史下行传输对应的目标非周期CSI报告，网络侧设备发送用于指示反馈历史下行传输对应的目标非周期CSI报告的DCI，使得终端设备接收到当前DCI之后，反馈之前未反馈或反馈失败的目标非周期CSI报告。
本公开实施例中，DCI中包括触发目标非周期CSI报告上报的指示域，其中，触发目标非周期CSI报告上报的指示域用于指示终端设备在第二预设发送时刻发送目标非周期CSI报告。
网络侧设备在发送的当前DCI中配置未反馈或反馈失败的目标非周期CSI报告上报的指示域，使得终端设备在接收到该当前DCI之后，在该DCI指示的第二预设发送时刻发送该目标非周期CSI报告，而无需网络侧设备重新发送RS，终端设备也无需重新计算非周期CSI报告。
本公开实施例中，所述上行控制信息发送方法还包括：
通过高层信令为终端设备配置预设有效时长，其中，预设有效时长用于指示若第一预设发送时刻与DCI的接收时刻之间的时间差不大于预设有效时长，或，第二预设发送时刻与第一预设发送时刻之间的时间差不大于预设有效时长，则终端设备发送目标非周期CSI报告。
网络侧设备可以通过高层信令为终端设备配置一个预设有效时长，即CSI报告有效窗，用以表示终端设备根据一个RS计算得到目标非周期CSI报告未反馈或反馈失败之后，该目标非周期CSI报告的有效时长。
网络侧设备发送用于指示反馈之前未反馈或反馈失败的目标非周期CSI报告的DCI之后，终端设备可以根据当前DCI的接收时刻与未反馈或反馈失败的目标非周期CSI报告的第一预设发送时刻之间的时间差，或，根据第一预设发送时刻与当前DCI指示的第二预设发送时刻之间的时间差，判断该未反馈或反馈失败的目标非周期CSI报告是否有效。
若时间差不大于预设有效时长，即该未反馈或反馈失败的目标非周期CSI报告有效，则终端设备在第二预设发送时刻发送该未反馈或反馈失败的目标非周期CSI报告；
若时间差大于预设有效时长，即该未反馈或反馈失败的目标非周期CSI报告失效，则终端设备在第二预设发送时刻发送预设值，例如，OOR。
通过发送用于指示终端设备反馈之前未反馈或反馈失败的目标非周期CSI报告的DCI，使得终端设备及时发送之前未反馈或反馈失败的目标非周期CSI报告，可以避免由于网络侧设备接收不到该未反馈或反馈失败的目标非周期CSI报告而重新发送RS，有效提高了资源利用率。
本公开实施例记载的技术方案，通过发送用于指示终端设备反馈历史下行传输对应的UCI的DCI，其中，该历史下行传输对应的UCI未反馈或反馈失败，使得终端设备及时发送该未反馈或反馈失败的UCI，可以避免网络侧设备进行数据重传，有效提高了资源利用率。
终端设备也无需重新根据RS计算非周期CSI报告，有利于节能。同时当前DCI的接收时刻与第二预设发送时刻可以采用较小的时间间隔，以达到快速上报的目的。
需要说明的是，本公开实施例中提及的“第一PDSCH组”表示当前下行传输，“第二PDSCH组”表示历史下行传输。
本公开实施例中提及的“第一PUCCH”表示与当前下行传输第一PDSCH组关联的PUCCH，“第二PUCCH”表示与历史下行传输第二PDSCH组关联的PUCCH。
