为了使本技术领域的人员更好地理解本申请方案，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、***、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其他步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
本申请实施例提供了一种上行控制信息传输方法及相关装置，下面结合附图对本申请实施例进行详细介绍。
请参阅图1a，图1a是本申请实施例提供的一种移动通信***10的架构图。该移动通信***10可以是长期演进(Long Term Evolution，LTE)***，也可以是基于LTE***的下一代演进***，如LTE-A(LTE-Advanced)***或第五代(5th Generation，5G)***(又称NR***)，还可以是基于5G***的下一代演进***，等等。本申请实施例中，术语“***”和“网 络”经常被可互换地使用，但本领域技术人员可理解其含义。
所述移动通信***10包括用户侧的终端100，网络侧的网络设备200，其中，终端100与网络设备200通信连接。
其中，所述网络设备200可以是5G基站、5G接入点AP等，此处不做唯一限定。基站可以包括宏基站，微基站，中继站，接入点等不同类型。在一些实施例中，基站可以被本领域技术人员称为基站收发机、无线基站、接入点、无线收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、节点B(NodeB)、演进的节点B(evolved NodeB，eNB或eNodeB)或者其它一些适当的术语。示例性地，在5G***中，基站被称为gNB。
其中，终端100可以散布于整个移动通信***中，并且每个终端100可以是静止的或者移动的。终端100还可以被本领域技术人员称为移动站、用户站、移动单元、用户单元、无线单元、远程单元、移动设备、用户设备、无线设备、无线通信设备、远程设备、移动用户站、接入终端、移动终端、无线终端、远程终端、手持设备、用户代理、移动客户端、客户端或者一些其它适当的术语。终端100可以是蜂窝电话、个人数字助理(Personal Digital Assistant，PDA)、无线调制解调器、无线通信设备、手持设备、平板电脑、膝上型计算机、无绳电话、无线本地环路(Wireless Local Loop，WLL)站等。终端100能够与移动通信***中的接入网设备进行通信。
本公开实施例描述的通信***以及业务场景是为了更加清楚地说明本公开实施例的技术方案，并不构成对本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着通信***的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
如图1b所示的终端100的结构示意图，本申请实施例提供的终端100包括处理器210、存储器220、通信接口230，以及一个或多个程序221，所述一个或多个程序221被存储在所述存储器220中，并且被配置由所述处理器210执行，所述程序221包括用于执行如本申请方法实施例所描述的方法。
目前，在PUSCH每一跳内，混合自动重传请求应答消息(Hybrid Automatic Repeat reQuest-Acknowledgement，HARQ-ACK)从前置解调参考信号(Demodulatin Reference Signal，DMRS)符号之后第一个符号开始映射。信道状态信息1(Channel State Information，CSI1)从PUSCH第一个非DMRS符号开始映射，且不映射在为HARQ-ACK保留资源单元(Resource Element，RE)位置，或HARQ-ACK资源单元RE映射位置，不与PUSCH DMRS频分复用。CSI2从PUSCH第一个非DMRS符号开始映射，可以映射在为HARQ-ACK保留资源单元RE位置，不映射在HARQ-ACK资源单元RE映射位置，不映射在CSI1资源单元RE映射位置，不与PUSCH DMRS频分复用。
上述HARQ-ACK，CSI1和CSI2在每个符号上所占资源单元RE位置为：上报信息映射的资源单元RE采用分布式映射，且间隔d为：
(1)若调度后未映射的上报信息符号个数大于正交频分复用(Orthogonal Frequency Division Multiplexing，OFDM)符号上可用的资源单元RE个数，则d＝1，仍有未映射的上报信息，则再继续在下一OFDM符号映射。
(2)若调度后未映射的上报信息符号个数小于OFDM符号上可用的资源单元RE个数， 则d＝floor(OFDM符号上可用的资源单元RE个数÷调度后的上报信息符号个数)。
在5G通信业务中，为提高资源利用效率，具有不同数据发送时长的用户终端可以复用相同的时频物理资源。例如，高可靠低延时(Ultra Reliable&Low Latency Communication，URLLC)用户终端的发送时长较短，为短时长(short time duration)用户终端；增强移动带宽(enhanced Mobile Broadband，eMBB)用户终端的发送时长较长，为长时长(long time duration)用户终端。为保证上述具有高可靠低时延业务，版本Rel-16NR引入上行信道包含PUCCH UCI和PUSCH配置为高优先级(High priority，HP)和低优先级(Low priority，LP)。当HP上行信道在时间上与LP上行信道重叠时，需要将低优先级上行链路信道LP UL channel丢弃，只发送HP UL channel。上述新空口(New Radio，NR)***中上行链路下行控制信息UL DCI触发非周期CSI(Aperiodic CSI，A-CSI)的步骤如下：
步骤一：高层信令无线资源控制(Radio Resource Control，RRC)新配置非周期A-CSI触发状态表，包含M个非周期A-CSI触发状态，M为正整数，一个非周期A-CSI触发状态包含N Rep个A-CSI上报相关配置信息，第j个非周期A-CSI上报的时隙间隔为Y j。高层信令RRC会配置DCI中包含的A-CSI请求字段的bit个数N。若2^N-1大于等于M时，进行步骤二；否则到步骤三。
步骤二：媒体接入控制层控制单元(Medium Access Control-Control-Control Element，MAC-CE)可以从非周期A-CSI触发状态表中选择出若干个非周期A-CSI触发状态
步骤三：DCI中包含信道状态信息请求字段(CSI request)，指示触发一个非周期A-CSI触发状态
步骤四：用户设备(User Equiment，UE)接收DCI后，测量CSI上报相关参考信号配置，
若此DCI只触发非周期A-CSI上报，则采用PUSCH反馈非周期A-CSI的时隙为
Figure PCTCN2022084832-appb-000001
其中Y j,j＝0,...,N Rep-1；m＝0-M。
若此DCI触发非周期A-CSI上报及PUSCH调度，则在UL DCI指示的PUSCH资源上报非周期A-CSI。
目前，为了便于基站进行上行增强覆盖，一个传输块(Transport Block，TB)的PUSCH跨多个时隙slot传输。此时，本发明给出一种UCI复用到TBoMS PUSCH的方法。
下面结合附图进行详细说明。
请参阅图2a，图2a是本申请实施例提供的上行控制信息传输方法的流程示意图，应用于如图1a所示的移动通信***10中的终端100和网络设备200，包括以下步骤：
步骤201，终端使用跨多个时隙传输传输块的TBoMS物理上行共享信道PUSCH的第一时隙发送上行控制信息UCI。
其中，所述TBoMS PUSCH是指至少占用2个连续时隙的PUSCH。
其中，所述第一时隙应理解为TBoMS PUSCH上开始映射UCI的第一个时隙，TBoMS PUSCH的该第一时隙之后的时隙也可以被复用映射UCI进行UCI的传输，如TBoMS PUSCH何PUCCH包括2个重叠时隙时，该第一个重叠时隙可以是2个重叠时隙的第一个时隙，且该2个重叠时隙的第二个时隙也会映射对应时隙的UCI以实现复用传输。
步骤202，网络设备使用TBoMS PUSCH的第一时隙接收UCI。
在一个可能的示例中，所述UCI包括以下至少一种：混合自动重传请求肯定应答HARQ-ACK和/或配置授权CG-UCI、信道状态信息CSI 1、CSI 2。
在本可能的示例中，所述TBoMS PUSCH中部分或者全部时隙与所述终端的PUCCH的传输时隙重叠。
在一个可能的示例中，所述第一时隙为所述TBoMS PUSCH与物理上行控制信道PUCCH重叠所处的时隙。
其中，若TBoMS PUSCH与PUCCH重叠所处的时隙包括多个时隙，则每个时隙均映射。
在一个可能的示例中，若所述UCI包括HARQ-ACK和/或所述CG-UCI，则所述HARQ-ACK和/或所述CG-UCI从所述TBoMS PUSCH的每个重叠时隙的前置解调参考信号DMRS符号之后第一个符号开始映射；或者，所述HARQ-ACK和/或所述CG-UCI从所述TBoMS PUSCH实际传输的每个重叠时隙的前置DMRS符号之后第一个符号开始映射；
若所述UCI包括HARQ-ACK和所述CG-UCI，则所述HARQ-ACK和所述CG-UCI联合编码后的信息从所述TBoMS PUSCH的每个重叠时隙的前置解调参考信号DMRS符号之后第一个符号开始映射；或者，所述HARQ-ACK和所述CG-UCI联合编码后的信息从所述TBoMS PUSCH实际传输的每个重叠时隙的前置DMRS符号之后第一个符号开始映射；
所述CSI1从所述TBoMS PUSCH的所述每个重叠时隙的第一个非DMRS符号开始映射，且不映射在为所述HARQ-ACK保留的资源单元位置和所述HARQ-ACK的资源单元映射位置，不与所述TBoMS PUSCH的DMRS频分复用；
所述CSI2从所述TBoMS PUSCH的每个重叠时隙的第一个非DMRS符号开始映射，能够映射在为所述HARQ-ACK保留的资源单元位置，不映射在所述HARQ-ACK的资源单元映射位置，不映射在所述CSI 1的资源单元映射位置，不与所述TBoMS PUSCH的DMRS频分复用。
举例来说，如图2b所示，假设PUCCH(图示为：HARQ-ACK+CSI1)与TBoMS PUSCH的第一个时隙(图示为slot n)部分重叠，TBoMS PUSCH跨时隙slot n、slot n+1，且时隙n的前置DMRS在符号2位置，非前置DMRS在符号6位置，时隙n+1情况相同，则按照HARQ-ACK、CSI1的映射要求，可以确定CSI1可以从重叠slot n的符号0开始映射，HARQ-ACK可以从重叠slot n的符号2位置的前置DMRS之后的第一个符号即符号3位置开始映射。
又举例来说，如图2c所示，假设PUCCH(图示为：HARQ-ACK+CSI1)与TBoMS PUSCH的第二个时隙(图示为slot n+1)部分重叠，TBoMS PUSCH跨时隙slot n、slot n+1，且时隙n的前置DMRS在符号2位置，非前置DMRS在符号6位置，时隙n+1情况相同，则按照HARQ-ACK、CSI1的映射要求，可以确定CSI1可以从重叠slot n+1的符号0开始映射，HARQ-ACK可以从重叠slot n+1的符号2位置的前置DMRS之后的第一个符号即符号3位置开始映射。
又举例来说，如图2d所示，假设PUCCH(图示为：HARQ-ACK+CSI1)与TBoMS PUSCH的第二跳(图示为slot n+1)部分重叠，TBoMS PUSCH跨时隙slot n、slot n+1，且时隙n的前置DMRS在符号2位置，非前置DMRS在符号6位置，时隙n+1情况相同，则按照HARQ-ACK、CSI1的映射要求，可以确定CSI1可以从第二跳即重叠时隙slot n+1的符号0 开始映射，HARQ-ACK可以从第二跳即重叠时隙slot n+1的符号2位置的前置DMRS之后的第一个符号即符号3位置开始映射。
可见，本示例中，***针对TBoMS PUSCH与PUCCH有重叠时隙的情况，能够从TBoMS PUSCH的每个重叠时隙映射对应的UCI，使得UCI仍然可以复用到TBoMS PUSCH上。
在一个可能的示例中，若所述TBoMS PUSCH与所述终端的PUCCH的传输时隙重叠所处的时隙在所述TBoMS PUSCH的第一个时隙，则所述UCI复用过程中采用速率匹配的方式占用所述TBoMS PUSCH中对应映射的资源单元；
若所述TBoMS PUSCH与所述终端的PUCCH的传输时隙重叠所处的时隙不在所述TBoMS PUSCH的第一个时隙，则所述UCI复用过程中采用打孔方式占用所述TBoMS PUSCH中对应映射的资源单元。
其中，UCI复用过程中采用速率匹配的方式占用PUSCH对应的RE资源，具体在计算PUSCH可用RE资源时将UCI复用所占RE先去除，再进行UL-SCH的速率匹配。
其中，UCI复用过程中采用打孔方式占用对应RE资源，打孔，非现有UCI复用，即计算PUSCH可用RE资源时不需要将非第一个时隙内UCI复用所占RE先去除，直接进行UL-SCH的速率匹配并先进行UL-SCH。在对应RE位置，UCI编码后的信息直接覆盖掉原UL-SCH编码后信息。
此外，设备在计算RE个数时也只是此时隙内分配的符号symbol个数，而非所有symbol个数。
可见，本示例中，设备能够灵活选择适配的复用方式，灵活便捷。
可以看出，本申请实施例中，终端能够使用TBoMS PUSCH的第一时隙发送UCI，实现了将UCI映射到TBoMS PUSCH上进行传输，从而有助于实现在TBoMB PUSCH上传输UCI，以提供上行控制信息辅助下行调度，提高***性能。
本申请实施例提供一种上行控制信息传输装置，该上行控制信息传输装置可以为终端。具体的，上行控制信息传输装置用于执行以上上行控制信息传输方法中终端所执行的步骤。本申请实施例提供的上行控制信息传输装置可以包括相应步骤所对应的模块。
本申请实施例可以根据上述方法示例对上行控制信息传输装置进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。本申请实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
