具体实施方式
下面详细描述本申请的实施例，实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，旨在用于解释本申请，而不能理解为对本申请的限制。
为了便于理解，首先介绍本申请涉及的术语。
1、上行控制信息(Uplink Control Information，UCI)
UCI包含的内容都是与当前终端设备状态相关的信息，例如当前终端设备是否需要请求上行资源、当前终端设备检测到的下行链路质量，终端设备能够区分出来的传输层个数等信息。
2、物理上行控制信道(Physical Uplink Control Channel，PUCCH)
PUCCH用于终端设备向基站发送与上行调度相关的信息，如调度请求、信道状况信息等。
3、物理上行共享信道(Physical Uplink Share CHannel，PUSCH)
PUSCH用于承载长期演进用户相关的上行业务以及上层信令数据。作为物理层主要的上行数据承载信道，可以调度传输上行数据，也可以承载控制信息。
4、解调参考信号(Demodulation Reference Signal，DMRS)
在通信技术中用于PUSCH和PUCCH信道的相关解调。
5、混合自动重传请求应答信息(Hybrid Automatic Repeat Request ACK，HARQ-ACK)
HARQ是将前向纠错码(Forward Error Correction，FEC)与自动重传请求(Automatic Repeat-reQuest，ARQ)结合起来使用，称为混合自动重传请求。HARQ-ACK为HARQ的应答或反馈信息。
6、信道状态信息(Channel State Information，CSI)
在无线通信领域，所谓的CSI，就是通信链路的信道属性。它描述了信号在每条传输路径上的衰弱因子，即信道增益矩阵H中每个元素的值，如信号散射(Scattering),环境衰弱(fading，multipath fading or shadowing fading),距离衰减(power decay of distance)等信息。CSI可以使通信***适应当前的信道条件，在多天线***中为高可靠性高速率的通信提供了保障。

本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile phone)、穿戴式设备、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)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote medical surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。

下面结合附图对本申请所提出的一种上行控制信息UCI的资源映射方法及装置进行详细的介绍。
图2为本申请一实施例的UCI的资源映射方法的流程示意图，该方法应用于终端设备，如图2所示，该方法包括：
S201，终端设备确定物理上行控制信道PUCCH和物理上行共享信道PUSCH重叠，且当前第一物理上行共享信道PUSCH上未承载解调参考信号DMRS。
终端设备通过物理上行信道与网络设备传输上行信息或数据。其中，物理上行信道包括物理上行控制信道(Physical Uplink Control Channel，PUCCH)和物理下行共享信道(Physical Uplink Shared Channel，PUSCH)。实现中上行信息可以为上行控制信道(Uplink Control Information，UCI)终端设备可以将UCI携带在PUCCH中传输，也可以携带在PUSCH中传输。
可选地，UCI信息可以包括混合自动重传请求应答信息(Hybrid Automatic Repeat Request ACK，HARQ-ACK)和/或信道状态信息(Channel State Information，CSI)。
在PUCCH中传输UCI时，同一个终端设备在同一个上行子帧，不能同时在PUCCH和PUSCH信道中传输信息，相关技术中PUCCH和采用多时隙重复传输的PUSCH可能存在PUCCH和物理上行共享信道PUSCH重叠，当PUSCH上承载有解调参考信号(Demodulation Reference Signal，DMRS)符号时，可以将UCI映射到与PUCCH存在重叠的PUSCH上传输。但是，在确定PUCCH和PUSCH重叠，且PUSCH上未承载有DMRS符号这一场景下，并未给出UCI进行资源映射方案，本申请实施例中，为PUCCH存在重叠的PUSCH，且PUSCH上未承载有DMRS符号这一场景，给出了下述UCI资源映射方案。
本申请实施例中，终端设备首先对当前信道状态进行检测，若当前信道状态指示PUCCH和PUSCH重叠，且当前第一PUSCH上未承载DMRS，终端设备可以执行步骤S202。
可选地，若PUCCH与PUSCH未发生重叠和/或当前第一PUSCH上承载DMRS时，可能在与PUCCH存在重叠的PUSCH上传输UCI。例如，UCI资源映射在PUSCH上进行传输时，不能映射在PUSCH的DMRS符号上，HARQ-ACK信息要映射在从PUSCH上最早的DMRS之后的第一个不承载DMRS的符号上，CSI可以从PUSCH上第一个不承载DMRS的符号开始进行资源映射。
S202，终端设备按照UCI的目标资源映射模式对UCI进行资源映射，并通过映射的资源向网络设备发送UCI；其中，目标资源映射模式用于将UCI映射到PUCSH资源。
在终端设备确定当前信道状态满足PUCCH和PUSCH重叠，且当前第一PUSCH上未承载DMRS，终端设备为了实现向网络设备传输UCI，需要按照UCI的目标资源映射模式对UCI进行资源映射。本申请实施例中，目标资源映射模式，用于指示将UCI映射到PUCSH资源上。在一些实现中，终端设备可以将UCI映射在当前传输的第一PUSCH资源上。在另一些实现中，终端设备可以将从重复传输的PUSCH中选取一个满足条件的PUSCH，将UCI映射到该满足条件的PUSCH资源上。例如选取的PUSCH需要满足该PUSCH上承载有DMRS和/或该选取的PUSCH需要与第一PUSCH相邻。可选地，终端设备在向PUSCH资源上映射UCI时，可以基于UCI包括的信息，分别按照信息各自的需求进行资源映射。
在一些实现中，终端设备可以配置有一种资源映射模式，也可以配置有多种资源映射模式。可选地，终端设备可以基于协议约定或者网络侧指示，从多个资源映射模式中确定出待使用的目标资源映射模式。
可选地，终端设备在完成UCI的资源映射后，可以通过映射的资源向网络设备发送UCI。
本申请实施例提出的UCI的资源映射方法，终端设备确定当前所处于PUCCH和PUSCH重叠，且当前第一PUSCH上未承载DMRS的场景下，按照目标资源映射模式将UCI映射到PUSCH上进行传输。本申请中，不仅可以实现在DMRS缺失的情况下，实现对UCI在PUSCH资源上的映射，而且可以在减小传输上的DMRS，降低DMRS密度的同时，提高了数据的传输量，降低了数据传输的码率，从而提高了接收信噪比及网络覆盖。

S301，终端设备确定PUCCH和PUSCH重叠，且当前第一PUSCH上未承载DMRS。
关于步骤S301的具体介绍，可参加上述实施例中相关内容的记载，此次不再赘述。
S302，终端设备从与第一PUSCH相邻的重复传输的PUSCH中，确定承载有DMRS的第二PUSCH 传输。
可选地，终端设备可以确定第一PUSCH的传输时刻或传输时隙，进而可以根据该第一PUSCH的传输时刻或者传输时隙，能够确定出位于该第一PUSCH的传输时刻或传输之后的至少一个重复传输的PUSCH，而且可以基于该PUSCH的配置信息，确定至少一个重复传输的PUSCH上是否承载有DMRS。终端设备可以从与第一PUSCH相邻的重复传输的PUSCH中，最终确定出承载有DMRS的第二PUSCH传输。
S303，终端设备将UCI映射到第一PUSCH和/或第二PUSCH的候选符号上。
可选地，终端设备可以从第一PUSCH和/或第二PUSCH上确定出适合映射UCI的候选符号，并将UCI映射到这些候选符号中的部分符号或完全符号上。
在一些实现中，目标资源映射模式可以包括终端设备可以将UCI映射到第一PUSCH的候选符号上；在另一些实现中，目标资源映射模式可以包括终端设备可以将UCI部分映射到第一PUSCH的候选符号上，还有部分映射到第二PUSCH的候选符号上。在又一些实施例中，目标资源映射模式可以包括终端设备可以将UCI映射到第二PUSCH的候选符号上。
可选地，UCI包括混合自动重传请求应答信息HARQ-ACK和/或信道状态信息CSI。作为一种可能的实现方式，目标资源映射模式可以包括将混合自动重传请求应答信息HARQ-ACK映射到第二PUSCH的第一候选符号的位置上；和/或，终端设备将信道状态信息CSI映射在第一PUSCH的第二候选符号的位置上。

S403，终端设备将HARQ-ACK映射到第二PUSCH的第一候选符号的位置上和/或将CSI映射在第一PUSCH的第二候选符号的位置上。
可选地，目标资源映射模式可以包括终端设备可以将第二PUSCH上最早承载DMRS的目标符号之后的第一个不承载DMRS的符号，作为第二PUSCH的第一候选符号。终端设备可以将HARQ-ACK映射到第一候选符号的位置上，即将HARQ-ACK映射到第二PUSCH上最早承载DMRS的目标符号之后的第一个不承载DMRS的符号。
可选地，终端设备可以确定第一PUSCH的第一个符号或者第一PUSCH上可用于承载DMRS的符号，作为第一PUSCH的第二候选符号。终端设备可以将CSI映射到第二候选符号的位置上，将CSI映射到第一PUSCH上可用于承载DMRS的符号的位置上。再例如终端设备将CSI映射到第一PUSCH 上第一个符号的位置上。
