下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的上行控制信息传输方法、装置及终端进行详细地说明。
如图2所示，本申请实施提供了一种上行控制信息传输方法，该方法的执行主体为终端，换言之，该方法可以由安装在终端的软件或硬件来执行。所述方法包括以下步骤。
S210、终端将上行控制信息UCI映射到用于上行传输的M个码字中的N个码字上进行上行传输；其中，所述M为大于或等于2的正整数，所述N为小于或等于M的正整数
所述终端进行上行传输进行上行传输，时支持多个码字，即M个码字同时传输。所述上行传输为通过上行信道，例如物理上行控制信道(Physical Uplink Control Channel，PUCCH)或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)，向网络侧设备进行传输。
终端上报UCI时，需要确定用于进行上行传输的码字的数量M，以及M个码字 中用于映射UCI的码字的数量N。例如，若终端用于进行上行传输的码字的数量M为大于或等于2的正整数，则可以将UCI映射到所述M个码字中的1个码字上进行传输，也可以将UCI映射到小于或等于M的N个码字上进行传输；若终端用于进行上行传输的码字的数量为1，则将UCI映射到该码字上进行传输。其中，所述M和N的数量可以根据实际的需要进行设定，但为了简便起见，在下面的实施例中均以M为2，所述N为1或2为例进行举例说明。
在一种实施方式中，所述步骤S210包括：
在所述N为1的情况下，所述终端将UCI映射到用于上行传输的M个码字中的第一码字上进行上行传输。
所述第一码字的确定方式可以多种多样，例如，可以由网络侧设备指示确定也可以由终端确定。在一种实施方式中，所述第一码字由以下至少一项确定：
所述M个码字中的第L个码字；其中，L为小于或等于M的正整数。所述终端可以将UCI固定映射到所述M个码字中的第L个码字上，例如将UCI始终映射到用于上行传输的两个码字中的第一个码字或第二个码字上；
所述M个码字中调制和编码方案(Modulation and coding scheme，MCS)的索引值最高的码字。如果M个码字对应不同的MCS，则所述终端可以将UCI映射到MCS的索引值最高的码字上；如果所述M个码字对应的MCS相同，则可以将UCI映射到默认的码字上；
所述M个码字中传输层数所最多的码字。如果M个码字对应的传输秩或传输层数不同，则所述终端可以将所述UCI映射到传输秩最高或者传输层数最多的码字止；如果所述M个码字对应的传输秩或传输层数相同，则所述终端可以将所述UCI映射到默认的码字上映射；
通过第一信令域指示的码字，即根据接收到的控制信令中的第一信令域的直接或间接指示确定第一码字。所述第一信令域可以包括以下至少之一：传输预编码矩阵指示(Transmitted Precoding Matrix Indicator，TPMI)信令域、探测参考信号资源指示(Sounding Reference Signal Resource Indicator，SRI)信令域、解调参考信号(Demodulation Reference Signal，DMRS)信令域；
所述M个码字中除用于传输数据的码字外的码字，即所述UCI与数据不在同一个码字上复用。
所述终端可以基于上述各项中的一项或者多项来确定所述第一码字。
在一种实施方式中，在所述终端将UCI映射在所述第一码字上时，在所述第一码字上进行速率匹配(rate matching)和/或数据打孔(puncturing)。可选的，在所述M个码字中除所述第一码字外的其它码字对应的时频单元(Resource Element，RE)上不传输数据。
在另一种实施方式中，步骤S210包括：
在所述N为大于或等于2的正整数的情况下，所述终端采用第一复用规则将UCI映射到用于上行传输的M个码字中的N个码字上进行上行传输。
在一种实施方式中，所述第一复用规则包括以下至少一项：
将所述UCI在所述N个码字上重复传输，且在每个码字上分别进行调制编码；
所述N个码字对应相同的调制和编码方法或者对应不同的调制和编码方法，例如网络侧设备在进行上行数据调度时指示所述N个码字对应的MCS可能相同或者不同；
所述N个码字对应相同的调制方法或者对应不同的调制方法，例如所述N个码字可以采用相同的编码方法不同的调制方法，或者所述N个码字可以采用不同的编码方法相同的调制方法；
将所述UCI分成N个数据块，并分别映射到所述N个码字上；其中，对所述N个数据块的划分具体可以根据与各码字对应的MCS，以及与各码字对应的传输层数来确定；
将所述UCI中信道状态信息CSI的第一部分(CSI part one)映射在一个码字上，即保证CSI part one不跨码字映射；
将所述UCI中CSI的第一部分在所述N个码字上重复传输；
将所述UCI中CSI的第一部分的宽带部分和CSI的第二部分(CSI part two)的宽带部分映射在同一个码字上；
将所述UCI映射到所述N个码字对应的所有传输层。
在一种实施方式中，在所述N个码字对应相同的MCS的情况下，所述UCI的调制和编码方法根据所述相同的MCS确定，所述相同的MCS可以由网络侧设备指示。
在一种实施方式中，在所述N个码字对应不同的MCS的情况下，所述UCI的调制和编码方法由以下至少一项确定：
所述N个码字对应的不同的MCS中的一个MCS，例如索引值最低或最高的MCS；
参考MCS，所述参考MCS可以由网络侧设备指示、协议约定或终端确定；
所述N个码字对应的功率偏移，所述功率偏移可以表示为betaoffset。
在一种实施方式中，所述N个码字对应的betaoffset根据以下至少一项确定：
高层信令指示；
物理层信令指示；
MCS；
传输层数；
偏移量(delta)。
在一种实施方式中，所述N个码字对应的betaoffset可以由高层信令或物理层信 令等分别指示N个betaoffset。
在另一种实施方式中，可以仅指示一个betaoffset，其它N-1个betaoffset可根据与各码字对应的MCS或者传输层数等来确定。
在另一种实施方式中，在仅指示一个betaoffset的情况下，其它N-1个betaoffset可基于固定的偏移量依次确定。
由上述实施例的技术方案可知，本申请实施例的通过将上行控制信息UCI映射到用于上行传输的M个码字中的N个码字上进行上行传输，能够解决如何传输UCI的问题。
基于上述实施例，在一种实施方式中，在步骤S210之前，所述方法还包括：
S200、所述终端确定用于映射所述UCI的码字数量N。
在一种实施方式中，所述终端可以根据从网络侧设备接收到的第一控制信令来确定用于映射所述UCI的码字数据N。
在一种实施方式中，所述第一控制信令可用于指示以下至少一项：
所述终端用于上行传输的码字的数量M；
用于映射UCI的码字的数量N；
各码字对应的MCS。
所述网络侧设备可通过所述第一控制信令来显示指示终端将UCI映射到一个码字上还是多个码字上，所述第一控制信令可以多种多样，为了简便起见，在下面的实施例中均以下行控制信息(Downlink Control Information，DCI)为例进行对所述第一控制信令的显示指示方法进行举例说明。
在一种实施方式中，可以通过所述第一控制信令中单独的一个第二信令域来指示。例如在N为1或2的情况下，可以在DCI中引入1比特(bit)的第二信令域，第二信令域为“1”时表示UCI在一个码字上复用，第二信令域为“0”时表示UCI在两个码字上复用。
在另一种实施方式中，可以在所述DCI中引入1比特第三信息域，并结合现有的上行共享信道指示(UpLink Shared Channel indicator，UL-SCH indicator)信令域(1比特)联合指示，共有4个状态，分别用于指示在用于上行传输的两个码字中是否可复用UCI，例如，可以分别用于指示：第一码字是仅用于上行共享信道(UL-SCH only)的码字，或者第二码字是UL-SCH only的码字，或者两个码字都UL-SCH only的码字。
在另一种实施方式中，对用于上行传输的两个码字可以分别引入对应的UL-SCH indicator信令域，分别用于指示每个码字是否可复用UCI。
在另一种实施方式中，所述终端还可以根据以下至少一项确定用于映射所述UCI的码字数据N：
所述UCI的开销，例如比特数；
所述UCI的类型；
所述UCI的时域特性。
所述终端可以根据所述UCI的开销、类型和时域特性中的至少一项来确定所述UCI在一个码字复用还是在多个码字复用。
在一种实施方式中，在所述第一控制信令指示以下至少一项的情况下，所述N为1：
所述上行传输只用于传输UCI(UCI only)；
所述上行传输用于传输UCI和上行数据，且用于上行传输的码字的数量M大于或等于2。
在一种实施方式中，在所述第一控制信令指示上行传输只用于传输UCI的情况下，所述终端确定用于上行传输的码字的数量M为1或者采用传输秩小于或等于4进行上行传输。在所述第一控制信令中指示UCI only的情况下，即使指示采用多个码字进行上行传输，所述终端也将退回到单个码字进行上行传输或者限制在传输秩小于或等于4进行上行传输。
由上述实施例的技术方案可知，本申请实施例通过显式或隐式的方法确定UCI映射的码字的数量N，再根据与N对应的复用规则将所述UCI映射到所述N个码字上，能够解决如何传输UCI的问题。
本申请实施例提供的上行控制信息传输方法，执行主体可以为上行控制信息传输装置。本申请实施例中以上行控制信息传输装置执行上行控制信息传输方法为例，说明本申请实施例提供的上行控制信息传输装置。
