以下结合附图，详细说明本公开各实施例提供的技术方案。
图1是本公开第一方面提供的一种上行控制信息传输方法的一个实施例的流程示意图，该方法100可以由终端设备(UE)执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，如图1所示，该方法100包括如下步骤：
S112，根据待传输的UCI的比特信息，生成承载比特信息的信号序列。
在本公开实施例中，通过信号序列来承载待传输的UCI的比特信息，可以通过信号序列的不同循环移位或者相位选准指示承载的比特信息，例如，循环移位{0,3,6,9}，分别用于指示{00,01,10,11}的比特信息，也就是说，在循环移位为3时，指示传输的比特信息为01。
在本公开实施例中，信号序列可以包括但不限于以下至少之一：M序列；ZC序列；GOLD序列；除M序列、ZC序列和GOLD序列之外的预设序列；M序列、ZC序列、GOLD序列和预设序列中的至少任意两个序列相乘获得的序列。即在本公开实施例中，信号序列可以采用上述序列中的任意一种，也可以是部分采用上述序列中的任意一种，其余部分根据实际应用中需要传输的其它信息确定，从而达到复用的目的。
在一个可选的实现方式中，在S112中，可以根据Q比特的比特信息，生成K个信号序列，每个信号序列承载M比特的比特信息，其中，Q、K和M为大于0的整数，
Figure PCTCN2020137369-appb-000001
即在该可选的实现方式中，根据Q比特的待传输的比特信息，生成K个信号序列，每个信号序列承载M比特的待传输的比特信息。例如，待传输的比特信息为11100011，每个信号序列承载2比特的待传输的比特信息，则生成4个信号序列，第1个信号序列承载比特信息中的前2比特，即11；第2个信号序列承载比特信息中的第3和4比特的比特信息，即10；第3个信号序列承载比特信息中的第5和6比特的比特信息，即00；第4个信号序列承载比特信息中的最后两比特，即11。
在本实施例中，可以对传输的比特信息的长度Q进行限定，即Q≤Qmax，其中，Qmax为预定义值或高层信令配置的值。
在一个可选的实现方式中，根据Q比特的比特信息，生成K个信号序列之前，可以根据待传输的UCI，得到Q比特的比特信息。即在该可选的实现方式中，根据待传输的UCI，得待传输的比特信息，该比特信息中至少包括了待传输的UCI的比特信息。
在本公开实施例中，Q可以是网络侧指示的，也可以是预先定义的。通过限定待传输的比特信息的长度，使得接收端(即网络侧设备)在恢复 传输的UCI信息时，可以更为方便的确定检测到比特信息中属于UCI的部分。
在具体应用中，网络侧指示的Q或者预先定义的Q可能与待传输的UCI的比特信息的长度一致，也可能不一致。因此，在一个可选的实现方式中，根据待传输的UCI，得到Q比特的比特信息时，若待传输的UCI的比特信息的长度L等于Q，则将待传输的UCI的比特信息作为Q比特的比特信息；若待传输的UCI的比特信息的长度L小于Q，根据预先设置或预设的高层信令的指示，确定是否需要在待传输的UCI的比特信息的尾部补0或1，如果是，则在待传输的UCI的比特信息的尾部补(Q-L)个0或1，得到Q比特的比特信息。
例如，假设待传输的UCI的比特信息为：1100100，而网络侧指示的UCI的比特信息的长度Q为10比特，根据预先设置或预设的高层信令的指示，在长度L小于Q时，补0或1，则待传输的比特信息为：1100100000或者1100100111。通过该可选的实现方式，可以在待传输的UCI的比特信息与网络侧指示的或预先定义的长度不一致时，通过补0或补1的方式得到网络侧指示的或预先定义的长度的待传输信息。
在上述可选的实现方式中，在一种可能的实现方式中，可以由高层信令指示在L小于Q的情况下，是否补1或0，以及是补1还是0，因此，在待传输的UCI的比特信息的尾部补(Q-L)个0或1可以包括：根据高层信令的指示确定，在待传输的UCI的比特信息的尾部补(Q-L)个0或1。通过该可能的实现方式，可以按照高层信令的指示确定在L小于Q的情况下是否补1或0以及是补1还是0，从而使得终端设备侧与网络侧可以统一。当然，并不限于此，也可以采用其它的实现方式，例如，在终端设备和网络侧预先配置在L小于Q的情况下的处理方式。
在上述可选的实现方式中，如果L大于Q，则说明当前UE选择的PUCCH资源的配置不适合当前的UCI传输，因此，可以重新选择其它配置的PUCCH资源，以传输当前的UCI信息，例如，选择网络侧配置的Q大于L的PUCCH配置。
上述方法100还包括：
S114，将信号序列映射到PUCCH资源的OFDM符号上传输。
在一个可能的实现方式中，在承载待传输的比特信息为K个信号序列时，在S114中，可以将K个信号序列映射到PUCCH资源的N个OFDM符号上，其中，N为大于0的整数。在该可能的实现方式中，N可以等于K，也可以大于K，即在该实现方式中，一个信号序列映射到一个OFDM符号上，一个信号序列至少在N个OFDM符号上映射一次。
在本实施例中，终端设备在传输UCI时，将待传输的比特信息承载到信号序列上，通过PUCCH资源的OFDM符号传输承载待传输的比特信息的信号序列，接收端通过检测PUCCH资源的OFDM符号上传输的信号序列，即可以获取到终端设备发送的UCI，而无需利用DMRS进行信道估计以获得UE传输的UCI，降低了UCI的接收复杂度。
在本公开实施例中，可以对N进行限定，在配置PUCCH资源时，可以为PUCCH资源设置一个配置参数，该配置参数用于指示PUCCH资源传输UCI信息使用的OFDM符号的最大数量，即Nmax，Nmax的取值可以为预定义值，也可以是高层信令配置的值。在这种情况下，N≤Nmax。例如，Nmax＝14，表明不能跨时隙传输。
在本公开实施例中，当前待传输的K个信号序列所需要的OFDM符号的数量N有可能大于当前选择的PUCCH资源配置的Nmax，在这种情况下，在执行S114之前，终端设备可以重新选择配置的Nmax大于或等 于当前待传输的K个信号序列所需要OFDM符号的数量N的PUCCCH资源。
在一个可选的实现方式中，为了确保UCI传输的可靠性，在S114中，终端设备可以将每个信号序列重复映射到P个OFDM符号上传输，每个信号序列每次映射到N个OFDM符号中的一个OFDM符号上传输，其中，每个OFDM符号在频域上占用S个资源块RB，P和S均为大于0的整数。在该实现方式中，N大于等于P*K。
在上述可选的实现方式中，可选地，可以对M和/或S的取值范围进行限定，以方便网络侧设备检测传输的UCI信息。因此，在一个可选的实现方式中，M≤Mmax，和/或，S≤Smax其中，Mmax为预定义值或高层信令配置的值，Smax为预定义值或高层信令配置的值。例如Mmax＝3，表明在1RB中可以传输的所有比特数。例如Smax＝1，代表传输UCI的序列长度占据1RB(序列长度为12)的传输过程。
在上述实现方式中，在传输UCI时，可以进行跳频传输，在这种情况下，在S114中，可以按照预先设置或网络侧的指示，将映射相同信号序列的不同OFDM符号设置在不同的频域位置上传输；或者，在P＝1的情况下，将N个OFDM符号中的前
Figure PCTCN2020137369-appb-000002
个OFDM符号与后
Figure PCTCN2020137369-appb-000003
个OFDM符号分别设置在不同的频域位置上传输，即在不重复映射的情况下，将传输UCI的N个OFDM符号中的前一半OFDM符号与后一半OFDM符号设置在不同的频域上传输。
在一个可选的实现方式中，N可以根据网络侧发送的指示确定，或者UE也可以根据需要待传输的比特信息确定N，即在S114之前，该方法还包括：根据网络侧发送的指示确定N；或者根据K确定N。在该实现方式中，在根据K确定N时，N可以为与P的乘积，P＝1时，即K个信号序列只映射一次的情况下，N等于K，而
Figure PCTCN2020137369-appb-000004
在一个可选的实现方式中，M可以根据网络侧的指示确定，也可以根据UE的需要配置，因此，在S114之前，该方法还可以包括：根据网络侧的指示确定M，或按照终端设备的需要配置M。若采用终端设备根据自身需求配置M的情况，则终端设备可以将M的取值通知网络侧设备，或者，终端设备也可以采用默认的M值。
在一个可选的实现方式中，在执行S114的过程中，若x＝Q mod M＝0，则生成承载Q比特的比特信息的K个信号序列；若x＝Q mod M≠0，则在Q比特的比特信息的最后x个比特信息后补(M-x)个0或1，再生成承载补(M-x)个0或1之后的比特信息的K个信号序列。具体地，可以根据高层信令确定是补0还1。例如，假设高层信令指示补0，Q比特的比特信息为10111010，M＝3，则最后确定的待传输的比特信息为：10111010，即映射第3个信号序列的OFDM符号上传输的比特信息为：100。
在一个可选的实现方式中，S可以根据网络侧的指示确定，也可以根据UE的需要配置，因此，在S114之前，该方法还可以包括：根据网络侧的指示确定S，或按照终端设备的需求配置S。
图2是本公开第一方面提供的一种上行控制信息传输方法的另一个实施例的流程示意图，该方法200可以由终端设备执行，换言之，该方法可以由安装在终端设备的软件或硬件来执行，如图2所示，该方法200包括如下步骤：
S212，根据待传输的UCI的比特信息，生成承载比特信息的K个信号序列，其中，每个信号序列承载M比特的比特信息，K和M为大于0的整数，
Figure PCTCN2020137369-appb-000005
Q为待传输的比特信息的长度。
S212可以采用上述S112中对应的各个实现方式，具体参见上述对S112的描述。
上述方法200还包括：
S214，将每个信号序列重复映射到PUCCH资源的N个OFDM符号中的P个OFDM符号上传输。
在本公开实施例中，P为大于0的整数，每个信号序列每次映射到一个OFDM符号上传输，每个信号序列重复映射P次。
在本公开实施例中，每个OFDM符号在频域上可以占用S个资源块RB，N、M和S均为大于0的整数，其中，可以对N、M和S进行限定，例如，N≤Nmax，和/或，M≤Mmax，和/或，S≤Smax，Nmax为预定义值或高层信令配置的值，Mmax为预定义值或高层信令配置的值，Smax为预定义值或高层信令配置的值。
其中，P为大于0的整数。P可以通过网络指示，或根据UE的需求进行配置，P≤Pmax，max值为预定义值或者由高层信令配置的值。例如Pmax＝1，代表只允许映射一次待传输的比特信息到OFDM符号上传输。
S214也可以采用S114的各个可选的实现方式，在此不再赘述。
在一个可选的实现方式中，S214可以包括：将K个信号序列中的每个信号序列按照第一预设映射方式或第二预设映射方式重复P个OFDM符号上传输。对于是采用第一预设映射方式还是第二预设映射方式可以根据预先定义确定，也可以根据网络侧的指示确定。
其中，第一预设映射方式包括：将承载UCI的前M比特的信号序列重复映射到PUCCH资源的前P个OFDM符号上，再将承载UCI的下M比特的信号序列重复映射到PUCCH资源的下P个OFDM符号上，直到完成K个信号序列的映射。也就是说，根据当前的PUCCH配置，从该PUCCH资源的起始OFDM符号开始，先连续在P个OFDM符号上映射第一个信号序列，即承载待传输的比特信息的前M比特信息的信号序列，完成后，再将承载待传输的比特信息的下M比特信息的信号序列映射到下P 个OFDM符号，直到完成承载待传输的比特信息中的所有信号序列的映射。
例如，假设网络侧配置PUCCH资源的每个OFDM符号(symbol)传输3比特的比特信息(即每个OFDM符号上映射一个信号序列，每个信号序列承载待传输的比特信息中的3比特的比特信息)，每3比特的比特信息重复映射到2个OFDM符号上传输(即每个信号序列重复映射2次，每次映射到一个OFDM符号)，UE待传输的UCI的比特信息为10比特，网络侧指示的Q(即总计传输比特长度)为10比特，待传输的UCI的比特信息为1101100111，UE在8个OFDM符号(即确定N＝8)上进行传输。则8个OFDM符号上传输的比特信息如图3所示。
又例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息重复映射到2个OFDM符号上，UE的待传输的UCI的比特信息的长度为6比特，传输的UCI数据为110110，总计传输比特长度为10比特(即Q＝10)，UE在8个OFDM符号(即确定N＝8)上进行传输。高层信令指示将待传输的UCI数据的比特信息进行补0至总传输比特数量，则待传输的比特信息为：1101100000。8个OFDM符号上传输的比特信息如图4所示。
又例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息重复映射到2个OFDM符号上，UE待传输的UCI的比特信息的长度为6比特，传输的UCI的比特信息为110110，总计传输比特长度为10比特，UE在8个OFDM符号(即确定N＝8)上进行传输。而根据高层信令，确定不需要进行补0或补1的操作，因此，待传输的比特信息为：110110。8个OFDM符号上传输的比特信息如图5所示。
其中，第二预设映射方式可以包括：将K个信号序列分别映射到PUCCH资源的前K个OFDM符号上，再将K个信号序列映射到PUCCH资源的下K个OFDM符号上，直到完成P次映射。也就是说，采用该映射方式，从指定的PUCCH资源的起始OFDM符号开始，依次将每个信号序列映射到一个OFDM符号，映射各信号序列的OFDM符号连续，然后，再从下一个OFDM符号开始，将各个信号序列再次映射在不同的时域资源上传输，直到完成P次的映射。
例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息传输重复2次，UE待传输的UCI数据长10比特，网络指示的总计传输比特(即Q)为10比特，传输数据为1101100111，UE在8个OFDM符号上进行传输。高层信令指示待传输数据的最后一组比特不足3的，通过补0补齐。则8个OFDM符号上传输的比特信息如图6所示。
又例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息传输重复2次，UE待传输的UCI数据长6比特，UCI数据为110110，网络指示的总计传输比特(即Q)为10比特，UE在8个符号上进行传输。根据高层信令配置，将传输比特进行补0至总计传输比特，待传输数据的最后一组比特不足3的，通过补0补齐。则8个OFDM符号上传输的比特信息如图7所示。
又例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息传输重复2次，UE待传输的UCI数据长6比特，UCI数据为110110，网络指示的总计传输比特(即Q)为10比特，UE在8个符号上进行传输。根据高层信令配置，不需要将传输比特补0至总计传输比特，且待传输数据的最后一组比特不足3的，通过补0补齐。则8个OFDM符号上传输的比特信息如图8所示。
在一个可选的实现方式中，在P大于1的情况下，将映射相同信号序列的不同OFDM符号设置在不同的频域位置上传输，或者，也可以将UCI的比特信息的不同部分映射到不同的频域位置上传输，以实现比特信息在时隙内跳频传输。在该可选的实现方式中，S214可以包括：按照预先设置或网络侧的指示，在P大于1的情况下，将映射相同信号序列的不同OFDM符号设置在不同的频域位置上传输，或者，在P＝1的情况下，即不对比特信息进行重复映射的情况下，将N个OFDM符号中的前
Figure PCTCN2020137369-appb-000006
与后
Figure PCTCN2020137369-appb-000007
Figure PCTCN2020137369-appb-000008
个OFDM符号分别设置在不同的频域位置上传输。
例如，当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息传输重复2次，UE待传输的UCI数据长10比特，网络指示的总计传输比特(即Q)为10比特，传输数据为1101100111，UE在8个OFDM符号上进行传输。高层信令指示待传输数据的最后一组比特不足3的，通过补0补齐，且高层信令指示传输相同信号序列的OFDM符号在频域的位置分别为RB1和RB2，UE采用上述第一预设映射方式进行映射。则8个OFDM符号上传输的比特信息如图9所示。
又例如，假设当前网络配置下，UE在每个OFDM symbol传输3比特的比特信息，每3比特的比特信息传输重复2次，UE待传输的UCI数据长10比特，网络指示的总计传输比特(即Q)为10比特，传输数据为1101100111，UE在8个OFDM符号上进行传输。高层信令指示待传输数据的最后一组比特不足3的，通过补0补齐，且高层信令指示传输相同信号序列的OFDM符号在频域的位置分别为RB1和RB2，UE采用上述第二预设映射方式进行映射。则8个OFDM符号上传输的比特信息如图10所示。
在一个可能的实现方式在，在S214的过程中，在第p次将第i个信号序列映射到PUCCH资源的一个OFDM符号上传输时，确定映射第i个信号序列的第j个OFDM符号上无法进行上行传输；其中，1≤p≤P，
Figure PCTCN2020137369-appb-000009
Figure PCTCN2020137369-appb-000010
1≤j≤N，则可以按照第一预设处理方式、第二预设处理方式或第三预设处理方式，处理K个信号序列的第p次映射。该可能的实现方式中，可以确定在上行资源发生冲突时的解决方案。
可选地，确定映射第i个信号序列的第j个OFDM符号上无法进行上行传输，包括但不限于：
一、确定第j个OFDM符号为高层信令半静态配置的下行资源，或者第j个OFDM符号为下行控制信息(Downlink Control Information，DCI)指示的下行资源或灵活OFDM符号；即第j个OFDM符号与DCI指示下行资源或灵活OFDM符号冲突。
二、确定第j个OFDM符号与网络侧指示的无线资源管理(Radio Resource Management，RRM)测量的时频资源冲突，例如，与同步信号和PBCH块(Synchronization Signal and PBCH Block，SSB)，或信道状态信息参考信号(Channel-state information Reference Signals，CSI-RS资源冲突；即第j个OFDM符号为网络侧指示的RRM测量所使用的时频资源。
三、确定第j个OFDM符号与传输除上行控制信息以外的其它上行信号的时频资源冲突。其中，其它上行信号包括但不限于同小区或邻小区的物理随机接入信道(Physical Random Access Channel，PRACH)、PUCCH或物理上行共享信道(Physical Uplink Shared Channel，PUSCH)。

在一个可选的实现方式中，网络侧可以指示UE在上行资源冲突时，采用上述第一预设处理方式、第二预设处理方式和第三预设处理方式中的一种方式进行处理，因此，在S214之前，方法100或者方法200还可以包括：接收网络侧发送的指示采用第一预设处理方式、第二预设处理方式或第三预设处理方式的指示命令。
图17是本公开第二方面提供的一种上行控制信息传输方法的一个实施例的流程示意图，该方法由网络侧设备执行，换言之，方法1700可以由安装在网络侧设备上的软件或硬件来执行。如图17所示，该方法1700可以包括以下步骤：
S1712，检测UE在PUCCH资源对应的OFDM符号上传输的信号序列。
在本实施例中，网络侧设备可以是基站或其它的网络侧设备。
在S1712中，网络侧设备可以根据UE选择的PUCCH资源的配置，检测UE在PUCCH资源对应的OFDM符号上传输的信号序列。
在本实施例中，UE可以按照上述方法100或方法200的各种可选的实现方式，传输UCI，具体可以参见上述方法100或方法200中的描述，在此不再赘述。
上述方法1700还包括：
S1714，根据预先设置的规则，获取检测到的每个信号序列上承载的比特信息。
在本实施例中，网络侧设备根据预先设置的规则，例如，根据预先设置的信号序列不同循环移位或者相位选准所指示的比特信息，例如，循环移位{0,3,6,9}，分别用于指示{00,01,10,11}的比特信息，也就是说，在循环移位为3时，指示传输的比特信息为01，从而使得网络侧设备可以获取到检测到的每个信号序列上承载的比特信息。并且，通过传输信号序列的OFDM符号在时间上顺序，可以得到UE上传的比特信息。
在本实施例中，信号序列可以为以下至少之一：M序列；ZC序列；GOLD序列；除M序列、ZC序列和GOLD序列之外的预设序列；M序列、ZC序列、GOLD序列和预设序列中的至少任意两个序列相乘获得的序列。
上述方法1700还包括：
S1716，根据UE传输UCI使用的传输参数，对获取到的比特信息进行重组，得到UE传输的UCI。
在本实施例中，网络侧设备可以按照UE传输UCI使用的传输参数，采用与UE传输UCI对应的方式，对从OFDM符号中检测到比特信息进行重组，得到UE传输的UCI。
与上述方法100和方法200对应，传输参数可以包括以下至少之一：
(1)其中，上述传输参数包括但不限于：传输UCI使用的OFDM符号的数量N。例如，如果N＝6，则网络侧设备检测UE使用的PUCCH资源的一个资源块的前6个OFDM符号，将每个OFDM符号上检测到的信号序列承载的比特信息按照传输的时间顺序进行重组，从而得到UE传输的UCI信息。
(2)传输的比特信息的长度Q，其中，Q为大于0的整数；例如，如果N＝6，Q＝8，则网络侧设备确定UE传输UCI使用的为PUCCH资源的前6个OFDM符号，将每个OFDM符号上检测到的信号序列承载的比特信息按照传输的时间顺序进行重组，得到一个比特信息，从该比特信息中截取前8个比特信息，从而得到UE传输的UCI信息。
(3)每个OFDM符号上传输的比特数M，其中，M为大于0的整数；根据M和N，网络侧设备可以确定传输的比特信息的总长度，从而确定包含UCI的比特信息，例如，如果N＝6，M＝3，则网络侧设备确定UE传输UCI使用的为PUCCH资源的前6个OFDM符号，将每个OFDM符号上检测到的信号序列承载的3比特的比特信息按照传输的时间顺序进行重组，得到18比特的比特信息，该18比特的比特信息中包含UCI。
(4)每个OFDM符号在频域上占用的RB数S，其中，S为大于0的整数；根据S，网络侧设备可以确定UE传输UCI使用的资源块数，从而可以进一步定位传输UCI的资源。例如，如果N＝6，M＝3，S＝1，则网络侧设备确定UE传输UCI使用的为PUCCH资源的一个资源块的前6个OFDM符号，将每个OFDM符号上检测到的信号序列承载的3比特的比特信息按照传输的时间顺序进行重组，从而得到UE传输的UCI信息。
(5)UCI在N个OFDM符号上重复映射的次数P，以及UCI在N个OFDM符号上的重复映射方式，其中，P为大于0的整数。
其中，重复映射方式可以包括上述的第一预设映射方式或第二预设映射方式，网络侧设备根据UCI在N个OFDM符号上的重复映射方式，可以按照对应的方式，将检测到的比特信息进行重组，以得到UE传输的UCI信息。例如，如果UE采用上述第一预设映射方式传输UCI，N＝8，M＝3，S＝1，P＝2，则网络侧设备将PUCCH资源上检测到的第1个信号序列承载的3比特的比特信息、第3个信号序列承载的3比特的比特信息、 第5个信号序列承载的3比特的比特信息和第7个信号序列承载的3比特的比特信息，按照传输的时间顺序进行重组，得到UE传输的UCI信息。
(6)各个OFDM符号的频域位置。
例如，在上述方法200的实施例中的UE在传输UCI时，将映射相同信号序列的不同OFDM符号设置在不同的频域位置上传输；或者，在P＝1的情况下，将N个OFDM符号中的前
Figure PCTCN2020137369-appb-000011
与后
Figure PCTCN2020137369-appb-000012
个OFDM符号分别设置在不同的频域位置上传输。则对应的，传输参数中包括了指示UCI占用的频域位置，根据该参数，网络侧设备可以确定将时隙中哪几个频域位置上获取的比特信息进行组合，以恢复出UE传输的UCI信息。
(7)在传输OFDM符号的时频资源存在冲突时的处理方式。
其中，存在冲突时的处理方式包括上述的第一预设处理方式、第二预设处理方式或第三预设处理方式，网络侧设备根据该传输参数，可以在重组UCI信息的过程中，通过判断预设的传输UCI的资源是否存在冲突来确定检测到的比特信息是否属于UCI信息，以及将哪些资源上传输的比特信息作为UCI信息，以确保恢复得到的UCI信息的准确性。
在具体应用中，传输参数并不限于上述列举出的参数，还可以包括其它对应的参数，具体与上述方法100和方法200中UE传输UCI的各个实现方式对应，例如，还可以包括：指示在UCI的比特信息的长度L小于Q的情况下，是否补0或1，以及是补0还1的参数。
与上述方法100和方法200对应，在一个可选的实现方式中，可以对上述涉及的部分传输参数的取值范围进行限定，包括但不限于以下至少之一：
N≤Nmax，Nmax为传输比特信息的PUCCH资源的一个配置参数，该配置参数的取值预定义值或高层信令配置的值；
Q≤Qmax，Qmax为预定义值或高层信令配置的值；
M≤Mmax，Mmax为预定义值或高层信令配置的值；
P≤Pmax，Pmax为预定义值或者由高层信令配置的值；
S≤Smax，Smax为预定义值或高层信令配置的值。
在一个可选的实现方式中，上述传输参数的一个或多个可以是网络侧设备指示UE配置的，因此，在该可选的实现方式中，在S1712之前，该方法还可以包括：向终端设备发送配置指示，配置传输参数中的一个或多个参数。
在上述实现方式中，网络侧设备可以根据高层信令指示发送上述配置指示，也可以根据网络侧设备自身的情况，确定上述传输参数中的一个或多个，并发送对应的配置指示，或者也可以根据各个PUCCH资源的配置，确定上述传输参数中的一个或多个，具体本实施例中不作限定。
在本实施例中，上述传输参数除了可以由网络侧设备配置，也可以是UE根据自身情况确定并通知网络侧设备的，还可以是高层信令统一向UE和网络侧设备配置的。具体本实施例中不作限定。
通过上述的UCI传输方法，网络侧设备可以通过检测PUCCH资源的OFDM符号传输的信号序列，获取UE传输的UCI，不需要利用解调参考信号(Demodulation Reference Signal，DMRS)进行信道估计还UE传输的UCI信息，从而降低了UCI信息的接收复杂度。
图18是实施本公开第一方面和第二方面提供的一种上行控制信息传输方法1800的示例性流程示意图，该方法1800由终端设备和网络侧设备执行，换言之，方法1800可以由安装在终端设备和网络侧设备上的软件或硬件来执行。如图18所示，方法1800包括以下步骤：
S1812，UE根据待传输的UCI的比特信息，生成承载比特信息的信号序列。
其中，S1812可以与S112或S212相同，具体可以参见上述对S112和S212的描述，在此不再赘述。
方法1800还包括：
S1814，UE将信号序列映射到PUCCH资源的OFDM符号上传输。
其中，S1814可以与上述S114或S214相同，具体可以参见上述对S114或S214的描述。
方法1800还包括：
S1816，网络侧设备检测UE在PUCCH资源对应的OFDM符号上传输的信号序列。
其中，S1816与上述S1712相同，具体可以参见上述对S1712的描述。
方法1800还包括：
S1818，网络侧设备根据预先设置的规则，获取检测到的每个信号序列上承载的比特信息。
其中，S1818与上述S1714相同，具体可以参见上述对1714的描述。
方法1800还包括：
S1820，网络侧设备根据UE传输UCI使用的传输参数，对获取到的比特信息进行重组，得到UE传输的UCI。
其中，S1820与上述S1716相同，具体可以参见上述对S1716的描述。
在本公开实施例中，UE根据待传输的UCI，生成承载UCI的比特信息的信号序列，将信号序列映射到PUCCH资源的OFDM符号上传输，网络侧设备通过检测PUCCH资源的OFDM符号上传输的信号序列，获取UE传输的UCI，不需要利用DMRS进行信道估计还UE传输的UCI信 息，从而降低了UCI信息的接收复杂度，另外，通过在PUCCH上传输信号序列的方式，可以提高PUCCH的抗干扰能力。
