Description

传输上行控制信息的方法和通信装置
本申请要求于2018年08月10日提交中国专利局、申请号为201810911047.1、申请名称为“传输上行控制信息的方法和通信装置”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
本申请涉及通信领域，并且更具体地，涉及一种传输上行控制信息的方法和通信装置。
背景技术
当前技术采用统一的反馈机制反馈上行控制信息(uplink control information，UCI)，例如，混合自动重传请求应答(hybrid automatic repeat request acknowledge，HARQ-ACK)、信道状态信息(channel state information，CSI)等，而不对UCI的反馈进行区分。但是，对于不同特性的UCI，比如不同传输时延或者可靠性需求的UCI，采用相同的机制进行反馈显然不太合理。因此，需要针对不同的UCI的反馈进行区分。
发明内容
本申请提供一种传输上行控制信息的方法和通信装置，能够根据UCI对应的业务类型对UCI进行反馈，提高UCI的传输性能。
第一方面，提供了一种发送上行控制信息的方法，该方法的执行主体可以是终端设备，也可以是应用于终端设备的芯片，下面以终端设备作为执行主体为例进行描述。该方法包括：确定第一调制与编码方案(modulation and coding scheme，MCS)表格，所述第一MCS表格是第一HARQ-ACK对应的下行数据传输所对应的MCS表格；根据所述第一MCS表格，确定所述第一HARQ-ACK的传输参数，所述第一HARQ-ACK的传输参数包括所述第一HARQ-ACK的下行分配索引(downlink assignment index，DAI)总数、所述第一HARQ-ACK的MCS偏移值和所述第一HARQ-ACK的编码速率中的一种或多种；根据所述第一HARQ-ACK的传输参数，确定所述第一HARQ-ACK占据的资源数目或者调制编码符号数目；在第一上行信道上发送所述第一HARQ-ACK。

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。
本申请实施例的技术方案可以应用于第五代(5th generation，5G)移动通信系统中的新空口(new radio，NR)或者未来的移动通信系统等。
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、个人数字助理(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，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，该网络设备可以是基站(node B，NB)、演进型基站(evolutional node B，eNB)、5G移动通信系统的NR中的基站、未来移动通信系统中的基站或WiFi系统中的接入节点等，本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。如无特别说明，在本申请中，5G系统和NR系统的表述可以互换。
在本申请实施例中，终端设备或网络设备包括硬件层、运行在硬件层之上的操作系统层，以及运行在操作系统层上的应用层。该硬件层包括中央处理器(central processing unit，CPU)、内存管理单元(memory management unit，MMU)和内存(也称为主存)等硬件。该操作系统可以是任意一种或多种通过进程(process)实现业务处理的计算机操作系统，例如，Linux操作系统、Unix操作系统、Android操作系统、iOS操作系统或windows操作系统等。该应用层包含浏览器、通讯录、文字处理软件、即时通信软件等应用。并且， 本申请实施例并未对本申请实施例提供的方法的执行主体的具体结构特别限定，只要能够通过运行记录有本申请实施例的提供的方法的代码的程序，以根据本申请实施例提供的方法进行通信即可，例如，本申请实施例提供的方法的执行主体可以是终端设备或网络设备，或者，是终端设备或网络设备中能够调用程序并执行程序的功能模块。
为便于理解本申请实施例，首先结合图1简单介绍适用于本申请实施例的通信系统。图1为适用于本申请实施例的系统100的示意图。如图1所示，该系统100包括网络设备101，该系统100还包括位于网络设备101覆盖范围之内的终端设备102以及终端设备103。网络设备101可以与终端设备102和终端设备103进行通信。应理解，图1中仅以网络设备101覆盖范围内的两个终端设备作为示例。显然，网络设备101的覆盖范围内也可以有更多的终端设备。
NR为下行数据传输配置了3张调制与编码方案(modulation and coding scheme，MCS)表格，其中，2张是针对增强移动宽带(enhanced mobile broadband，eMBB)业务的：包括1张复用LTE的256正交振幅调制(quadrature amplitude modulation，QAM)表格(记为MCS表格#1)和一张复用LTE的64QAM表格(记为MCS表格#2)；1张是针对极高可靠性低时延通信(ultra reliable and low latency communication，URLLC)的新的64QAM表格(记为MCS表格#3)。区别于正常的64QAM表格，新的64QAM表格对应的频谱效率(spectrum efficiency，SE)更低，可以理解为相同MCS索引(index)下，新的64QAM表格中的元素对应的频谱效率比正常的64QAM表格中的元素的频谱效率更低，或者说新的64QAM表格涵盖的编码速率取值范围下限比正常64QAM表格涵盖的编码速率取值下限更低，可以指示更低码率传输，适用于保障URLLC的高可靠性。也就是说，MCS表格可以间接指示业务类型，终端设备根据下行数据传输对应的MCS表格可以确定下行数据传输对应的业务类型。例如，若MCS表格为MCS表格#3，可以确定对应的下行数据传输的业务类型为URLLC业务；若MCS表格为MCS表格#1和MCS表格#2的一种，可以确定对应的下行数据传输的业务类型为eMBB业务。
为适应不同业务类型，对不同业务类型的下行数据传输进行HARQ反馈的HARQ-ACK的传输参数(比如DAI总数、MCS偏移值等)可能有不同需求。而现有技术中仅配置一套用于传输HARQ-ACK的传输参数，比如DAI总数、MCS偏移值等，这种方式显然不够灵活，例如，不能适应不同业务类型的时延和/或可靠性等需求。
有鉴于此，本申请提供了一种传输上行控制信息的方法，通过将MCS表格与HARQ-ACK的传输参数关联，对使用特定MCS表格的下行数据传输所对应的HARQ-ACK，设置对应的传输参数，可以适应不同业务类型的时延和/或可靠性等需求。
需要说明的是，本申请并不限定MCS表格为上文所描述的NR配置的MCS表格，也不限定MCS表格与业务类型的对应关系为上文所描述的NR配置的MCS表格与业务类型的对应关系。应理解，本申请也适用于系统配置其他多张MCS表格以及该多张表格对应多种业务类型的情形。
图2示出了本申请实施例的传输上行控制信息的方法的示意性流程图200。该方法200可以应用于图1所示的系统100，但本申请实施例不限于此。
S202，网络设备确定第一MCS表格。
示例性的，网络设备可以根据第一下行数据传输对应的业务类型确定MCS表格(即， 第一MCS表格)。例如，当第一下行数据传输对应的业务类型为URLLC业务时，可以确定第一MCS表格为MCS表格#3。其中，第一MCS表格为M个MCS表格中的一个，M为大于1的正整数。另外，所述M个MCS表格还包括第二MCS表格，第一MCS表格与第二MCS表格所隐式指示的业务类型不同。所述M个MCS表格可以为协议或系统预定义的。
本申请中，第一下行数据传输可以包括动态调度的PDCSH、免授权的PDCSH和SPS PDSCH。
可选地，网络设备确定第一MCS表格后，可以通过半静态配置的方式向终端设备配置第一MCS表格，例如，网络设备可以通过高层参数MCS-table配置第一MCS表格。或者，网络设备可以动态配置第一MCS表格。比如，在第一MCS表格为MCS表格#3时，网络设备可以使用新的RNTI(记为X-RNTI)加扰调度该第一下行数据传输的DCI，以通知终端设备第一下行数据传输对应的MCS表格为MCS表格#3。
还应理解，网络设备进行第一下行数据传输后，终端设备可以通过HARQ-ACK向网络设备反馈第一下行数据传输是否被正确接收。本申请中，将对第一下行数据传输对应的HARQ反馈记作：第一HARQ-ACK。
S204，终端设备确定第一MCS表格。
如上文所述，第一MCS表格是第一HARQ-ACK对应的第一下行数据传输所对应的MCS表格。应理解，本申请中的HARQ-ACK包括ACK或NACK。本申请实施例中，终端设备对第一下行数据传输进行反馈时，可以首先确定第一下行数据传输对应的MCS表格，然后根据第一MCS表格确定第一HARQ-ACK的传输参数(如下文S206所述)。
与S202对应，在S204中，终端设备确定第一MCS表格具体可以是：如果高层没有配置新的RNTI(记为X-RNTI)，则可以确定第一MCS表格为高层参数MCS-table配置的表格；如果高层配置了X-RNTI，则根据对第一DCI进行加扰的RNTI以及第一DCI的格式与传输第一DCI的PDCCH所在的搜索空间类型确定第一MCS表格，其中，第一DCI为调度第一下行数据传输的DCI。示例性的，当该第一DCI不是回退DCI或传输该第一DCI的PDCCH所在的搜索空间不是公共搜索空间，且对该第一DCI进行加扰的RNTI是X-RNTI时，可以确定第一MCS表格为MCS表格#3，即URLLC业务所对应的MCS表格；当该第一DCI不是回退DCI或传输该第一DCI的PDCCH所在的搜索空间不是公共搜索空间，且对该第一DCI进行加扰的RNTI不是X-RNTI时，第一MCS为MCS表格#1和MCS表格#2中的一个；当该DCI是回退DCI且该DCI的搜索空间是公共搜索空间，可以确定第一MCS表格为MCS表格#1和MCS表格#2中的一个。在本申请中，回退DCI是指一种特殊的DCI格式，例如，NR中的DCI format 0_0或1_0，其特征是该DCI中所有比特域是否存在以及每个比特域的位置、宽度都是预定义的，不需要高层参数配置。
S206，网络设备根据第一MCS表格，确定第一HARQ-ACK的传输参数。
S208，终端设备根据第一MCS表格，确定第一HARQ-ACK的传输参数。
S210，网络设备根据第一HARQ-ACK的传输参数，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目。
S212，终端设备根据第一HARQ-ACK的传输参数，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目。
网络设备可以根据第一MCS表格所隐式指示的业务类型，确定第一HARQ-ACK的传输参数。相当于是说，MCS表格与HARQ-ACK的传输参数具有对应关系。相应地，终端设备可以根据该该对应关系，确定第一HARQ-ACK的传输参数。
第一HARQ-ACK的传输参数可以包括第一HARQ-ACK的DAI总数，第一HARQ-ACK的MCS偏移值和第一HARQ-ACK的编码速率中的一种或多种。其中，第一HARQ-ACK的DAI总数用于确定第一HARQ-ACK码本，进一步地可以确定第一HARQ-ACK占据的资源数目或者说调制编码符号数目；第一HARQ-ACK的MCS偏移值用于确定第一HARQ-ACK占据的资源数目或者说调制编码符号数目；第一HARQ-ACK的编码速率用于确定HARQ-ACK编码后的比特数目，进一步可以确定第一HARQ-ACK占据的资源数目或者说调制编码符号数目。
应理解，本申请中根据第一HARQ-ACK的DAI总数和/或第一HARQ-ACK的MCS偏移值所确定的第一HARQ-ACK占据的资源数目的单位可以是资源粒子(resource element)，根据第一HARQ-ACK的编码速率所确定的第一HARQ-ACK占据的资源数目的单位可以是资源块(resource block，RB)。
可以理解的是，上述S206和S210可以合并为：网络设备根据第一MCS表格，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目；S208和S212也可以合并为：终端设备根据第一MCS表格，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目。
S214，终端设备在第一上行信道上发送第一HARQ-ACK。
可以理解的是，终端设备在发送第一HARQ-ACK之前，需要对第一HARQ-ACK进行信道编码、速率匹配和调制，将第一HARQ-ACK调制在对应的调制编码符号上，然后将该调制编码符号映射到对应的RE上进行发送。
S216，网络设备根据第一HARQ-ACK占据的资源数目或者调制编码符号数目，在第一上行信道上接收第一HARQ-ACK。
具体地，网络设备根据确定的第一HARQ-ACK占据的资源数目或调制编码符号数目，在第一上行信道上对第一HARQ-ACK进行解调、反速率匹配和信道译码，获得第一HARQ-ACK的原始比特信息。
在本申请实施例中，第一HARQ-ACK用于对第一下行数据传输进行HARQ反馈，第一下行数据传输所使用的MCS表格为第一MCS表格，第一MCS表格可以隐式指示第一HARQ-ACK对应的业务类型，终端设备可以根据第一HARQ-ACK对应的业务类型，确定第一HARQ-ACK对应的传输参数。进一步的，终端设备可以根据该传输参数，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目。然后终端设备可以在第一上行信道上发送第一HARQ-ACK。相应地，网络设备可以根据该传输参数，确定第一HARQ-ACK占据的资源数目或者调制编码符号数目，然后在第一上行信道上对第一HARQ-ACK进行接收。
因此，本申请实施例的传输上行控制信息的方法，终端设备可以根据下行数据传输所使用的MCS表格，确定对该下行数据传输进行HARQ反馈的HARQ-ACK的传输参数，从而能够适应HARQ-ACK对应的业务类型对时延和/或可靠性的需求。
可选地，所述第一上行信道可以是数据信道也可以是控制信道。在第一上行信道为数 据信道时，若第一上行信道上还承载上行数据，那么在S212中，终端设备可以根据第一HARQ-ACK的DAI总数，确定第一HARQ-ACK码本，再根据第一HARQ-ACK码本大小确定第一HARQ-ACK的比特数。进一步地，终端设备可以根据第一HARQ-ACK的比特数、第一上行信道的传输块大小TBS、以及第一HARQ-ACK的MCS偏移值，确定第一HARQ-ACK在第一上行信道上传输占据的资源数目或者说调制编码符号数目。如果第一上行信道承载了A-CSI，但没有承载上行数据，终端设备可以根据第一HARQ-ACK的MCS偏移值和调度第一上行信道的上行授权(UL Grant)所指示的编码速率，计算第一HARQ-ACK的编码速率，然后根据第一HARQ-ACK的比特数和计算得到的第一HARQ-ACK的编码速率，确定第一HARQ-ACK在第一上行信道上传输占据的资源数目或调制编码符号数目。需要注意的是，当第一HARQ-ACK的比特数目小于等于2时，需要计算给第一HARQ-ACK预留的时频资源数目，计算预留时频资源是根据第一HARQ-ACK比特数目等于2确定的。
在第一上行信道为PUCCH的情况下，终端设备可以根据第一HARQ-ACK的编码速率确定第一HARQ-ACK占据的资源数目或者调制编码符号数目，具体地可以参照现有技术，此处不再赘述。
以下，针对第一上行信道为分别为上行数据信道(例如，第一PUSCH)和上行控制信道(例如，第一PUCCH)两种场景，对S208的具体实现方式进行举例说明。S206与S208类似，因此下文中将不再详述。
场景一：
第一上行信道为上行数据信道，即，第一上行信道为第一PUSCH
在此场景下，第一HARQ-ACK的传输参数可以包括第一HARQ-ACK的DAI总数，或包括第一HARQ-ACK的MCS偏移值，或包括第一HARQ-ACK的DAI总数和第一HARQ-ACK的MCS偏移值。
(1)在第一HARQ-ACK的传输参数包括第一HARQ-ACK的MCS偏移值的情况下，终端设备可以根据方式一至方式三中的任一种确定第一HARQ-ACK的MCS偏移值。
方式一
终端设备可以根据第一映射关系集和MCS偏移值比特域中的值，确定第一HARQ-ACK的MCS偏移值。更具体的，终端设备可以根据第一映射关系集、第一HARQ-ACK的比特数和MCS偏移值比特域中的值，确定第一HARQ-ACK的MCS偏移值。
其中，MCS偏移值比特域是调度第一下行数据传输的DCI中的一个比特域，第一映射关系集为N个映射关系集中的一个，N为大于1的正整数。所述N个映射关系集与所述M个MCS表格对应，第一映射关系集与第一MCS表格对应，所述映射关系集表示在不同的HARQ-ACK比特数的情况下，MCS偏移值比特域的取值与MCS偏移值的对应关系。另外，所述N个映射关系集还包括第二映射关系集，第二映射关系集与第二MCS表格对应。例如，在第一MCS表格为MCS表格#3的情况下，第二MCS表格可以是MCS表格#1或者MCS表格#2。或者，在第一MCS表格为MCS表格#1或者MCS表格#2的情况下，第二MCS表格可以是MCS表格#3。
举例来说，系统或者网络设备可以预先定义或预先配置两个映射关系集，即，映射关 系集#1和映射关系集#2，映射关系集#1与MCS表格#3对应，映射关系集#2与MCS表格#1和MCS表格#2对应。若第一MCS表格为MCS表格#3，则可以确定第一映射关系集为映射关系集#1。终端设备可以根据映射关系集#1和MCS偏移值比特域中的值，并结合第一HARQ-ACK的比特数，确定第一HARQ-ACK的MCS偏移值。
应理解，对于不同比特数的HARQ-ACK，在MCS偏移值比特域中的值相同的情况下，MCS偏移值可能不同。
需要注意的是，在该实施例中，终端设备可以先根据第一MCS表格确定第一映射关系集，再根据MCS偏移值比特域中的值和第一映射关系集确定第一HARQ-ACK的MCS偏移值。或者，终端设备可以先根据MCS偏移值比特域中的值和N个映射关系集确定出N个候选MCS偏移值，再根据第一MCS表格从N个候选MCS偏移值中确定出第一HARQ-ACK的MCS偏移值。可以理解的是，为了得到第一HARQ-ACK的MCS偏移值，相关的输入参数包括第一MCS表格、N个映射关系集、HARQ-ACK的比特数以及MCS偏移值比特域的取值。具体实现时，可以根据上述各个输入参数中的一个、两个或三个确定出中间变量，然后再根据该中间变量以及剩余的输入参数再确定第一HARQ-ACK的MCS偏移值；或者也可以根据上述四个输入参数直接得到第一HARQ-ACK的MCS偏移值。本申请对如何根据上述四个输入参数得到第一HARQ-ACK的MCS偏移值的步骤和顺序不做限定。
为使本领域技术人员更好的理解本申请，以映射关系集#1所表示的映射关系如表1所示，映射关系集#2所表示的映射关系如表2所示为例，对方式一进行说明。表1中的a11，a12，a13，a14，a21，a22，a23，a24，a31，a32，a33和a34为正实数，表2中的b11，b12，b13，b14，b21，b22，b23，b24，b31，b32，b33和b34为正实数。
以MCS偏移值比特域中的值为“00”，且第一HARQ-ACK的比特数为4为例。若第一MCS表格对应的MCS映射关系集为映射关系集#1，那么根据表1所示，可以确定第一HARQ-ACK的MCS偏移值为a21；若第一MCS表格对应的MCS映射关系集为映射关系集#2，那么根据表2所示，可以确定第一HARQ-ACK的MCS偏移值为b21。

表2
Figure PCTCN2019099990-appb-000002
应理解，本申请不限定MCS偏移值比特域的位数和在不同的映射关系集中MCS偏移值比特域的可能取值与MCS偏移值的对应关系，表1和表2仅是示例性说明，并不应对本申请构成任何限定。
方式二
终端设备根据方式一中描述的第一映射关系集和D个MCS偏移值比特域中的第一MCS偏移值比特域，确定第一HARQ-ACK的MCS偏移值。
其中，D个MCS偏移值比特域是调度第一下行数据传输的DCI中的比特域，D为大于1的整数。D个MCS偏移值比特域与所述M个MCS表格对应，D个MCS偏移值比特域包括第一MCS偏移值比特域，第一MCS表格与第一MCS偏移值比特域对应。另外，所述D个MCS偏移值比特域还包括第二MCS偏移值比特域，第二MCS偏移值比特域与第二MCS表格对应。
应理解，方式二中的第一MCS偏移值比特域可以对应于方式一中的MCS偏移值比特域。
方式三
终端设备根据第一MCS表格，基于预先配置的P个MCS偏移值组确定第一HARQ-ACK的MCS偏移值。其中，P为大于1的正整数。
其中，P个MCS偏移值组与M个MCS表格对应，第一MCS偏移值组与第一MCS表格对应，第一MCS偏移值组为所述P个MCS偏移值组中的一个。每个MCS偏移值组包括HARQ-ACK的比特数不同的情况下对应的MCS偏移值，第一HARQ-ACK的MCS偏移值可以是第一MCS偏移值组中的一个MCS偏移值。另外，所述P个MCS偏移值组还包括第二MCS偏移值组，第二MCS偏移值组与第二MCS表格对应。
举例来说，可以配置两个MCS偏移值组，每个MCS偏移值组包括HARQ-ACK的比特数是1～2、3～11和大于11三种情况下的MCS偏移值，第一MCS偏移值组可以与MCS表格#3对应，第二MCS偏移值组可以与MCS表格#1和MCS表格#2对应。若第一MCS表格为MCS表格#3，则终端设备结合第一HARQ-ACK的比特数，可以从第一MCS偏移值组中确定出第一HARQ-ACK的MCS偏移值。
应理解，网络设备可以通过高层信令预先配置所述P个MCS偏移值组，所述P个MCS偏移值组也可以是协议预定的。本文所涉及的高层信令可以为无线资源控制(radio resource control，RRC)信令或媒体接入控制(medium access control，MAC)控制元素(control element，CE)等。
(2)在第一传输参数包括第一HARQ-ACK的DAI总数的情况下，终端设备可以根据方式一或方式二确定第一HARQ-ACK的DAI总数。
方式一
终端设备根据DCI中的第一DAI比特域，确定所述第一HARQ-ACK的DAI总数。
其中，所述DCI用于调度所述第一下行数据传输，所述第一DAI比特域为所述DCI中的Q个DAI比特域中的一个，Q为大于1的正整数，所述Q个DAI比特域与所述M个MCS表格对应，所述第一DAI比特域与所述第一MCS表格对应。另外，所述Q个DAI比特域还包括第二DAI比特域，第二DAI比特域与第二MCS表格对应。
终端设备可以根据第一DAI比特域中的值和DAI比特域的取值与DAI总数的映射关系确定所述第一HARQ-ACK的DAI总数。应理解，DAI比特域的取值与DAI总数的映射关系可以是现有技术中规定的映射关系。另外，每个DAI比特域的位数可以是2。
进一步地，每个DAI比特域可以包括两个子域，其中一个子域指示基于传输块(TB-based)的HARQ-ACK的DAI总数，一个指示基于码块组(code block group based，CBG-based)的HARQ-ACK的DAI总数。终端设备根据第一MCS表格、第一HARQ-ACK是TB-based HARQ-ACK还是CBG-based HARQ-ACK，可以确定第一HARQ-ACK的DAI总数。应理解，在此情况下，每个子域可以是2比特，一个DAI比特域可以是4比特，但本申请实施例对此不作限定。
方式二
终端设备可以根据第一MCS表格，确定R个DAI总数中与第一MCS表格对应的第一DAI总数。第一DAI总数即第一HARQ-ACK的DAI总数。其中，R为大于1的正整数。
其中，所述R个DAI总数与所述M个MCS表格对应。另外，所述R个DAI总数还包括第二DAI总数，第二DAI总数与第二MCS表格对应。
应理解，网络设备可以通过高层信令预先配置所述R个DAI总数。可以理解的是，所述R个DAI总数也可以是协议预定的。
场景二：
第一上行信道为上行控制信道，即，第一上行信道为第一PUCCH
在此场景下，第一HARQ-ACK传输参数可以包括第一HARQ-ACK的编码速率。
可选地，终端设备可以根据第一MCS表格，确定S个编码速率中与第一MCS表格对应的第一编码速率，即第一HARQ-ACK的编码速率。其中，S为大于1的正整数。
其中，所述S个编码速率与所述M个MCS表格对应。另外，所述S个编码速率还包括第二编码速率，第二编码速率与第二MCS表格对应。
应理解，网络设备可以通过高层信令预先配置所述S个编码速率。可以理解的是，所述S个编码速率也可以是协议预定的。
应理解，上文中介绍的终端设备根据第一MCS表格确定第一HARQ-ACK的传输参数的方式仅是示例性说明，但不应对本申请构成任何限定。在具体实施时，网络设备可以采用其他的方式将MCS表格与HARQ-ACK的传输参数关联起来，终端设备可以采用相应地方式确定与特定MCS表格对应的HARQ-ACK的传输参数。
上文中主要介绍了HARQ-ACK的传输参数与MCS表格关联的方案，可替换的， HARQ-ACK的传输参数可以与加扰DCI的RNTI关联，该DCI用于调度与该HARQ-ACK对应的下行数据传输。
如前文所述，在高层配置了X-RNTI的情况下，终端设备可以根据调度第一下行数据传输的DCI的扰码RNTI以及该DCI的格式与所在搜索空间，确定第一MCS表格。当扰码RNTI是X-RNTI且该DCI不是回退DCI或不在公共搜索空间时，可以确定第一MCS表格为MCS表格#3，否则为MCS表格#1和MCS表格#2中的其中一个。也就是说，在高层配置了X-RNTI的情况下，加扰DCI的RNTI与下行数据传输的MCS表格关联。因此，可以将加扰DCI的RNTI与该DCI所调度的下行数据传输对应的HARQ-ACK的传输参数关联，根据加扰DCI的RNTI的不同，可以配置对应的HARQ-ACK的传输参数。终端设备在传输HARQ-ACK时，可以首先确定与该HARQ-ACK对应的RNTI，然后再根据所确定的RNTI，确定HARQ-ACK的传输参数。
应理解，网络设备可以采用与上文中的实施例类似的方法，将加扰DCI的RNTI与该DCI所调度的下行数据传输对应的HARQ-ACK的传输参数关联。相应地，终端设备可以采用类似的方法，根据加扰DCI的RNTI，确定该DCI所调度的下行数据传输对应的HARQ-ACK的传输参数。比如，可以将上文中场景一下的方式一中的N个映射关系集与加扰DCI的RNTI关联，这样可以根据加扰DCI的RNTI，确定该DCI所调度的下行数据传输对应的HARQ-ACK的MCS偏移值。HARQ-ACK的传输参数具体如何与加扰DCI的RNTI关联，可以参照上文的描述，此处不再赘述。
NR的下行信道测量机制是：网络设备发送信道状态信息参考信号(channel state information reference signal，CSI-RS)，终端设备测量CSI-RS得到信道信息，反馈包括CQI的CSI。NR配置了3张CQI表格，其中，2张是复用LTE的256QAM表格(记为CQI表格#1)和64QAM表格(记为CQI表格#2)；1张是针对极高可靠性低时延通信URLLC的新的64QAM表格(记为CQI表格#3)。另外，CQI表格#1和CQI表格#2对应的目标误块率(block error rate，BLER)是10％，而CQI表格#3对应的目标BLER是0.001％。也就是说，CQI表格可以间接指示业务类型，终端设备可以根据所使用的CQI表格确定业务类型。例如，若CQI表格为CQI表格#3，可以确定业务类型为URLLC业务；若CQI表格为CQI表格#1和CQI表格#2中的一种，可以确定业务类型为eMBB业务。
针对业务类型的不同，进行CSI反馈时使用的传输参数(比如MCS偏移值、编码速率等)，可能有不同需求。而现有技术中仅配置一套用于传输CSI的传输参数，这种方式显然不够灵活，例如，不能适应不同业务类型的时延和/或可靠性等需求。
有鉴于此，本申请提供了一种传输上行控制信息的方法，通过将CQI表格与CSI的传输参数关联，对使用特定CQI表格的CSI设置对应的传输参数，可以适应不同业务类型的时延和/或可靠性等需求。
需要说明的是，本申请并不限定CQI表格为上文所描述的NR配置的CQI表格，也不限定CQI表格与业务类型的对应关系为上文所描述的NR配置的CQI表格与业务类型的对应关系。应理解，本申请也适用于系统配置其他多张CQI表格以及该多张表格对应多种业务类型的情形。
图3示出了本申请实施例的传输上行控制信息的方法的示意性流程图300。该方法300可以应用于图1所示的系统100，但本申请实施例不限于此。
S302，网络设备确定第一CQI表格。
示例性的，网络设备可以根据即将调度的业务(例如，第二下行数据传输)对应的业务类型确定第一CQI表格。例如，当第二下行数据传输对应的业务类型为URLLC业务时，可以确定第一CQI表格为CQI表格#3。其中，第一CQI表格为T个CQI表格中的一个，T为大于1的正整数。另外，所述T个CQI表格还包括第二CQI表格，第一CQI表格与第二CQI表格所隐式指示的业务类型不同。所述T个CQI表格可以为协议或系统预定义的。
本申请中，第二下行数据传输可以包括动态调度的PDCSH、免授权的PDCSH和SPS PDSCH。
可选地，网络设备确定第一CQI表格后，可以通过半静态配置的方式向终端设备配置第一CQI表格，例如，网络设备可以通过高层参配置第一CQI表格。或者，网络设备可以动态配置第一CQI表格。比如，网络设备可以预先配置所述T个CQI表格，在其希望终端设备根据第一CQI表格上报CQI时，可以通过DCI或其他信令激活第一CQI表格。
可选地，终端设备可以通过第一CSI反馈与第一CQI表格对应的CQI。
S304，终端设备确定与第一CSI对应的第一CQI表格。
本申请实施例中，终端设备反馈第一CSI时，可以首先确定第一CQI表格，然后根据第一CQI表格确定第一CSI的传输参数(如下文S306所述)。S304的实现方式对应于S302的实现方式，具体可以参照S302的描述，这里不再赘述。
S306，网络设备根据第一CQI表格，确定第一CSI的传输参数。
S308，终端设备根据第一CQI表格，确定第一CSI的传输参数。
S310，网络设备根据第一CSI的传输参数，确定第一CSI占据的资源数目或者说调制编码符号数目。
S312，终端设备根据第一CSI的传输参数，确定第一CSI占据的资源数目或者说调制编码符号数目。
第一CSI的传输参数包括第一CSI的MCS偏移值，或包括第一CSI的编码速率，或包括第一CSI的MCS偏移值和第一CSI的编码速率。
应理解，第一CSI的MCS偏移值包括第一CSI的第一部分的MCS偏移值和所述第一CSI的第二部分的MCS偏移值，即第一CSI中CSI part1的MCS偏移值和第一CSI中CSI part2的MCS偏移值。其中，第一CSI中CSI part1的MCS偏移值可以用于确定第一CSI中CSI part1占据的资源数目或者说调制编码符号数目，第一CSI中CSI part2的MCS偏移值可以用于确定第一CSI中CSI part2占据的资源数目或者说调制编码符号数目。第一CSI的编码速率用于确定第一CSI编码后的比特数目，进一步可以确定第一CSI占据的资源数目或者说调制编码符号数目。
应理解，本申请中根据第一CSI的MCS偏移值所确定的第一CSI占据的资源数目的单位可以是RE。根据第一CSI的编码速率所确定的第一CSI占据的资源数目的单位可以是资源块(resource block，RB)。
可以理解的是，上述S306和S310可以合并为：网络设备根据第一CQI表格，确定第一CSI占据的资源数目或者调制编码符号数目；S308和S312也可以合并为：终端设备根据第一CQI表格，确定第一CSI占据的资源数目或者调制编码符号数目。
S314，终端设备在第一上行信道上发送第一CSI。
可以理解的是，终端设备在发送第一CSI之前，需要对第一CSI进行信道编码、速率匹配和调制，将第一CSI调制在对应的调制编码符号上，然后将该调制编码符号映射到对应的RE上进行发送。
S316，网络设备根据第一CSI占据的资源数目或者调制编码符号数目，在第一上行信道上接收第一CSI。
具体地，网络设备根据确定的第一CSI占据的资源数目或调制编码符号数目，在第一上行信道上对第一CSI进行解调、反速率匹配和信道译码，获得第一CSI的原始比特信息。
本申请实施例中，第一CQI表格可以指示第一CSI所对应的业务类型，终端设备可以根据第一CSI所对应的业务类型，确定第一CSI的传输参数。进一步的，终端设备可以根据该传输参数，确定第一CSI占据的资源数目或者调制编码符号数目。然后终端设备可以在第一上行信道上发送第一CSI。相应地，网络设备可以根据该传输参数，确定第一CSI占据的资源数目或者调制编码符号数目，然后在第一上行信道上对第一CSI进行接收。
因此，本申请实施例的传输上行控制信息的方法，终端设备可以根据上报CSI时所使用的CQI表格，确定CSI的传输参数，从而能够适应CSI对应的业务类型对时延和/或可靠性的需求。
可选地，所述第一上行信道可以是数据信道也可以是控制信道。在第一上行信道为数据信道时，若第一上行信道上还承载上行数据，在S312中，终端设备可以根据第一CSI中CSI part1的比特数、第一上行信道的传输块大小TBS、以及第一CSI中CSI part1的MCS偏移值，确定第一CSI中CSI part1在上行信道上传输占据的资源数目或者说调制编码符号数目。以及，终端设备可以根据第一CSI中CSI part2的比特数、第一上行信道的传输块大小TBS、以及第一CSI中CSI part2的MCS偏移值，确定第一CSI中CSI part2在第一上行信道上传输占据的资源数目或者说调制编码符号数目。
在第一上行信道为PUCCH的情况下，终端设备可以根据第一CSI的编码速率确定第一CSI占据的资源数目或者调制编码符号数目，具体地可以参照现有技术，此处不再赘述。
以下，针对第一上行信道为上行数据信道(例如，第一PUSCH)和上行控制信道(例如，第一PUCCH)两种场景，对S308的具体实现方式进行举例说明。S306与S308类似，因此下文中将不再详述。
场景一：
第一上行信道为第一PUSCH
在此场景下，第一CSI的传输参数可以包括第一CSI的MCS偏移值。终端设备可以根据方式一至方式三中的任一种确定第一CSI的MCS偏移值。
方式一
终端设备根据第一映射关系集组所包括的V个映射关系集中的第一映射关系集和MCS偏移值比特域中的值，确定第一CSI中CSI part1的MCS偏移值，以及根据第二映射关系集组所包括的V个映射关系集中的第一映射关系集和MCS偏移值比特域中的值，确定第一CSI中CSI part2的MCS偏移值。
具体来讲，第一映射关系集组和第二映射关系集组均包括V个映射关系集，每个映射关系集组中的V个映射关系集与所述T个CQI表格对应，且所述V个映射关系集中的第 一映射关系集与第一CQI表格对应，V为大于1的整数。第一映射关系集组中的每个映射关系集表示在不同的CSI part1的比特数的情况下，MCS偏移值比特域的取值与MCS偏移值的对应关系，第二映射关系集组中的每个映射关系集表示在不同的CSI part2的比特数的情况下，MCS偏移值比特域的取值与MCS偏移值的对应关系。第一映射关系集组中的第一映射关系用于确定第一CSI中CSI part1的MCS偏移值，第二映射关系集组中的第一映射关系用于确定第一CSI中CSI part2的MCS偏移值。另外，每个映射关系集组中的V个映射关系集还包括第二映射关系集，第二映射关系集与第二CQI表格对应。
举例来说，系统或者网络设备可以预先定义或预先配置两个映射关系集组，每个映射关系集组包括两个映射关系集，即，映射关系集#1和映射关系集#2，映射关系集#1可以与CQI表格#3对应，映射关系集#2可以与CQI表格#1和CQI表格#2对应。若第一CQI表格为CQI表格#3，则可以确定第一映射关系集为映射关系集#1。其中，第一映射关系集组中的每个映射关系集指示CSI part1的比特数属于不同区间(如1～11和>11)情况下，第一比特域取值的取值分别为00,01,10,11时对应的MCS偏移值。第二映射关系集组中的每个映射关系集指示CSI part2的比特数属于不同区间(如1～11和>11)情况下，第一比特域取值的取值分别为00,01,10,11时对应的MCS偏移值。在确定第一CQI表格对应的映射关系集为映射关系集#1的情况下，终端设备可以根据第一映射关系集组中的映射关系集#1和MCS偏移值比特域中的值，并结合CSI part1的比特数，确定CSI part1的MCS偏移值，根据第二映射关系集组中的映射关系集#1和MCS偏移值比特域中的值，并结合CSI part2的比特数，确定CSI part2的MAC偏移值。
应理解，对于不同比特数的CSI，在MCS偏移值比特域中的值相同的情况下，MCS偏移值可能不同。
可以理解的是，为了得到第一CSI的MCS偏移值，相关的输入参数包括第一CQI表格、两个映射关系集组、第一CSI中的CSI part1的比特数、第一CSI中的CSI part2的比特数以及MCS偏移值比特域的取值。具体实现时，可以根据上述各个输入参数中的一个或多个确定出中间变量，然后再根据该中间变量以及剩余的输入参数再确定第一CSI的MCS偏移值；或者也可以根据上述五个输入参数直接得到第一CSI的MCS偏移值。本申请对如何根据上述五个输入参数得到第一CSI的MCS偏移值的步骤和顺序不做限定。
方式二
终端设备根据方式一中描述的各映射关系集组中的第一映射关系集和F个MCS偏移值比特域中的第一MCS偏移值比特域，确定第一CSI的MCS偏移值。
其中，F个MCS偏移值比特域是调度第一下行数据传输的DCI中的比特域。F个MCS偏移值比特域与所述T个CQI表格对应，第一CQI表格与第一MCS偏移值比特域对应，F为大于1的整数。另外，所述F个MCS偏移值比特域还可以包括第二MCS偏移值比特域，第二MCS偏移值比特域与第二CQI表格对应。
应理解，方式二中的第一MCS偏移值比特域可以对应于方式一中的MCS偏移值比特域。
方式三
终端设备根据第一CQI表格，基于预先配置的两个MCS偏移值集合确定第一CSI的MCS偏移值。
其中，每个MCS偏移值集合可以包括W个MCS偏移值组，W个MCS偏移值组与所述T个CQI表格对应，W为大于1的整数。每个MCS偏移值集合中的第一MCS偏移值组与第一CQI表格对应，每个MCS偏移值组包括CSI的比特数不同情况下对应的MCS偏移值。CSI part1的MCS偏移值可以是第一个MCS偏移值集合中第一MCS偏移值组中的一个MCS偏移值，CSI part2的MCS偏移值可以是第二个MCS偏移值集合中第一MCS偏移值组中的一个MCS偏移值。另外，每个MCS偏移值集合中的多个MCS偏移值组还包括第二MCS偏移值组，第二MCS偏移值组与第二CQI表格对应。
举例来说，可以配置两个MCS偏移值集合，每个MCS偏移值集合中包括两个MCS偏移值组。每个MCS偏移值集合中的每个MCS偏移值组指示CSI的比特数属于不同区间(如1～11和>11)情况下的MCS偏移值，每个MCS偏移值集合中的第一MCS偏移值组可以与CQI表格#3关联，第二MCS偏移值组可以与CQI表格#1和CQI表格#2关联。若第一CQI表格为CQI表格#3，则终端设备结合CSI part1的比特数、第一个MCS偏移值集合中的第一MCS偏移值组，可以确定CSI part1的MCS偏移值，结合CSI part2的比特数、第二个MCS偏移值集合中的第一MCS偏移值组，可以确定CSI part2的MCS偏移值。

S404，终端设备确定第一CSI的传输参数。
其中，第一CSI为由DCI触发的且在短格式PUCCH上报的A-CSI，第一CSI指示第一业务类型，第一业务类型可以是URLLC业务，但本申请实施例对此不作限定。进一步地，第一CSI对应的CQI表格为CQI表格#3。
第一CSI的传输参数包括第一CSI的MCS偏移值和第一CSI的编码速率中的一种或两种。应理解，第一CSI的MCS偏移值包括第一CSI中CSI part1的MCS偏移值和第一CSI中CSI part2的MCS偏移值。
需要说明的是，方法400中，不满足第一CSI的配置的CSI都可以称为第二CSI。也就是说，不同时满足下述配置的CSI都为第二CSI：(1)DCI触发；(2)在短格式PUCCH上报；(3)A-CSI。其中，第二CSI和第一CSI所指示的业务类型不同。进一步地，不同时满足下述配置的CSI都为第二CSI：(1)DCI触发；(2)在短格式PUCCH上报；(3) A-CSI；(4)该CSI对应的CQI表格为CQI表格#3。
本申请实施例中，网络设备可以针对第一CSI和第二CSI分别配置对应的传输参数。
S406，网络设备根据第一CSI的传输参数，确定第一CSI占据的资源数目或者说调制编码符号数目。
S408，终端设备根据第一CSI的传输参数，确定第一CSI占据的资源数目或者说调制编码符号数目。
第一CSI的传输参数包括第一CSI的MCS偏移值或包括第一CSI的编码速率，或包括第一CSI的MCS偏移值和第一CSI的编码速率。应理解，第一CSI的MCS偏移值包括第一CSI的第一部分的MCS偏移值和所述第一CSI的第二部分的MCS偏移值，即第一CSI中CSI part1的MCS偏移值和第一CSI中CSI part2的MCS偏移值。其中，第一CSI中CSI part1的MCS偏移值可以用于确定第一CSI中CSI part1占据的资源数目或者调制编码符号数目，第一CSI中CSI part2的MCS偏移值可以用于确定第一CSI中CSI part2占据的资源数目或者调制编码符号数目。第一CSI的编码速率用于确定第一CSI编码后的比特数目，进一步可以确定第一CSI占据的资源数目或者说调制编码符号数目。
应理解，本申请中根据第一CSI的MCS偏移值所确定的第一CSI占据的资源数目的单位可以是RE。根据第一CSI的编码速率所确定的第一CSI占据的资源数目的单位可以是RB。
可以理解的是，上述S402和S406可以合并为：网络设备确定第一CSI占据的资源数目或者调制编码符号数目；S404和S408也可以合并为：终端设备确定第一CSI占据的资源数目或者调制编码符号数目。
S410，终端设备在第一上行信道上发送第一CSI。
可以理解的是，终端设备在发送第一CSI之前，需要对第一CSI进行信道编码、速率匹配和调制，将第一CSI调制在对应的调制编码符号上，然后将该调制编码符号映射到对应的RE上进行发送。
S412，网络设备根据第一CSI占据的资源数目或者说调制编码符号数目，接收第一CSI。
具体地，网络设备根据确定的第一CSI占据的资源数目或调制编码符号数目，在第一上行信道上对第一CSI进行解调、反速率匹配和信道译码，获得第一CSI的原始比特信息。
本申请实施例的传输上行控制信息的方法，第一CSI和第二CSI分别对应一套传输参数，在需要传输第一CSI时，终端设备确定第一CSI的传输参数，根据第一CSI的传输参数确定第一CSI占据的资源数目或者调制编码符号数目。然后终端设备可以在第一上行信道上发送第一CSI。相应地，网络设备可以根据该传输参数，确定第一CSI占据的资源数目或者调制编码符号数目，然后在第一上行信道上对第一CSI进行接收。因此，根据本申请实施例的方法，终端设备能够灵活反馈CSI。
可选地，所述第一上行信道可以是数据信道也可以是控制信道。在第一上行信道为数据信道时，若第一上行信道上还承载上行数据，在S408中，终端设备可以根据第一CSI中CSI part1的比特数、第一上行信道的传输块大小TBS、以及第一CSI中CSI part1的MCS偏移值，确定第一CSI中CSI part1在上行信道上传输占据的资源数目或者说调制编码符号数目。以及，终端设备可以根据第一CSI中CSI part2的比特数、第一上行信道的 传输块大小TBS、以及第一CSI中CSI part2的MCS偏移值，确定第一CSI中CSI part2在第一上行信道上传输占据的资源数目或者说调制编码符号数目。
在第一上行信道为PUCCH的情况下，终端设备可以根据第一CSI的编码速率确定第一CSI占据的资源数目或者调制编码符号数目，具体地可以参照现有技术，此处不再赘述。
以下，针对第一上行信道为上行数据信道(例如，第一PUSCH)和上行控制信道(例如，第一PUCCH)两种场景，对S404的具体实现方式进行举例说明。S402与S404类似，因此下文中将不再详述。
