图1中的终端120可以是用户设备(User Equipment，UE)。UE可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网(Core Network)进行通信。终端又可称为接入终端、终端设备、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、无线网络设备、用户代理或用户装置。终端可以是蜂窝电话、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、个人数字处理(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设备、车载设备、可穿戴设备或物联网、车辆网中的终端设备以及未来网络中的任意形态的终端设备等。
在图1所示的通信系统下，网络设备110和终端120间相互通信。如，终端120可以 在PUCCH向网络设备110发送UCI，相应地，网络设备110接收终端120发送的UCI，以实现终端120与网络设备110之间的其他上下行传输。
具体地，终端120向网络设备发送的UCI可以包括混合自动重传请求(hybrid automatic repeat request，HARQ)确认(acknowledgement，ACK)信息、信道状态信息(channel state information，CSI)和/或调度请求信息等。
终端120上可以配置有重复次数与正交覆盖码的对应关系。其中，每个重复次数可以对应多个正交覆盖码。终端120上也可以配置有重复次数和正交覆盖码的共轭的对应关系。正交覆盖码的共轭可以称为解正交覆盖码。
如重复次数M可以对应M个正交覆盖码，这M个正交覆盖码可以为：[1,1,1,…1]，
Figure PCTCN2018085651-appb-000001
具体地，重复次数4对应的4个正交覆盖码包括：[1，1，1，1]，[1，j，-1，-j]，[1，-1，1，-1]，[1，-j，-1，-j]。重复次数2对应的2个正交覆盖码包括：[1，1][1，j]。
网络设备110上可以配置有重复次数与正交覆盖码的对应关系，或者重复次数与正交覆盖码的共轭的对应关系。可以将正交覆盖码的共轭称为解正交覆盖码。同理，每个重复次数可以对应多个正交覆盖码或多个解正交覆盖码。
通常情况下，若网络设备110上配置的是重复次数与正交覆盖码的对应关系，则该对应关系可以与终端120上配置的重复次数与正交覆盖码的对应关系相同；若网络设备110上配置的是重复次数与解正交覆盖码的对应关系，则该解正交覆盖码可以为终端上的正交覆盖码的共轭。
图2是由终端执行的通信方法的示意性流程图。应理解，图2示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图2中的各个操作的变形。此外，图2中的各个步骤可以按照与图2呈现的不同的顺序来执行，并且有可能并非要执行图2中的全部操作。
S210，终端将待传输上行控制信息重复N次，得到第一数据段。其中，N为正整数。
具体地，终端将待传输上行控制信息重复N次，可以包括：终端将待传输上行控制信息调制所得的星座点符号重复N次。如，待传输上行控制信息调制后的星座点符号为3个，则这3个星座点符号重复4次后得到12个星座点符号，这12个星座点符号即为第一数据段。
其中，待传输上行控制信息的星座点符号可以是待传输上行控制信息经过正交相移键控(quadrature phase shift keyin，QPSK)调制，得到的QPSK符号；或者，也可以是待传输上行控制信息经过移相键控(binary phase shift key，BPSK)调制，得到的BPSK符号。
其中，若承载终端120的上行控制信息的上行控制信道所使用的子载波数是确定的，则终端可以根据子载波数和重复次数确定终端120的上行控制信息的编码比特数。
例如，终端120的上行控制信息的上行控制信道所使用的子载波数为12，上行控制信息的重复次数为2，终端120的调制方式为QPSK，则说明终端120的上行控制信息重复前的QPSK符号为6个。又因为每两个编码比特可以调制为1个QPSK符号，则说明上行控制信息的编码比特应为12个。
S220，终端根据重复次数N，确定正交覆盖码。
具体地，终端可以根据N以及终端上配置的重复次数与正交覆盖码的对应关系，确定与N对应的正交覆盖码。
如终端上配置了重复次数4对应的正交覆盖码包括[1，j，-1，-j]，则终端可以根据N＝4和该对应关系，得到正交覆盖码[1，j，-1，-j]。
可选的，若终端120根据重复次数N确定的正交覆盖码为多个，则终端120还可以根据网络设备110发送的正交覆盖码的索引，从重复次数N对应的多个正交覆盖码中确定该索引对应的正交覆盖码。
应注意，本申请实施例并不限制S210和S220的执行顺序，如S220也可以位于S210之前。
S230，终端将第一数据段与正交覆盖码相乘，得到第二数据段。
也就是说，终端将S210中得到的第一数据段与S220中得到的正交覆盖码相乘，得到第二数据端。终端将重复得到的数据段与正交覆盖码相乘，可以使得上行控制信息的频域数据在载波上交错排列，从而有助于多个终端复用相同的资源传输各自的上行控制信息。
例如，可以将待传输上行控制信息的3个QSPK符号重复第一次得到的3个QSPK符号乘上正交覆盖码[1，j，-1，-j]中的1，将这3个QSPK符号重复第二次得到的3个QSPK符号乘上正交覆盖码[1，j，-1，-j]中的j，将这3个QSPK符号重复第三次得到的3个QSPK乘上正交覆盖码[1，j，-1，-j]中的-1，将这3个QSPK符号重复第四次得到的3个QSPK乘上正交覆盖码[1，j，-1，-j]中的-j。最终，12个QSPK符号乘上正交覆盖码[1，j，-1，-j]得到的结果即为第二数据段。
终端将重复得到的数据段与正交覆盖码相乘，可以使得上行控制信息的频域数据在载波上交错排列，从而有助于多个终端复用相同的资源传输各自的上行控制信息。
例如，有4个终端：终端1、终端2、终端3和终端4，每个终端的待传输上行控制信息分别包括3个QPSK符号；每个终端将各自的3个QPSK符号重复4次，分别得到12个QPSK符号；四个终端的正交覆盖码与[1，1，1，1]，[1，j，-1，-j]，[1，-1，1，-1]，[1，-j，-1，-j]一一对应，每个终端分别将自己的QPSK符号与对应的正交覆盖码相乘，并进行DFT处理，可以得到如图3所示的频域梳状结构图。从图3可知，这四个终端的频域梳状结构交错排列，互不冲突。
S240，终端发送第二数据段。
此处所说的终端发送第二数据段，如图4所示，具体可以包括：对第二数据段进行离散傅里叶变换(discrete fourier transform，DFT)；将DFT得到的数据映射到上行控制信道对应的资源上，具体地，可以是将DFT得到的数据映射到上行控制信道对应的子载波上；将映射得到的数据进行快速傅里叶逆变换(inverse fast fourier transform，IFFT)，得到时域数据；发送时域数据。
图2所示的通信方法中，可选地，重复次数N可以是终端自己确定的，也可以是终端从网络设备获取的。
终端自己确定重复次数N时，具体地，终端可以根据上行信道状态信息确定重复次数N，或者，终端可以根据待传输上行控制信息的星座点符号数M确定重复次数N。
终端根据上行信道状态信息确定重复次数N时，上行信道状态信息指示的信号质量越好，重复次数可以越大。
例如，在终端的上行信号质量大于某个阈值时，确定重复次数为8；小于某个阈值时，确定重复次数为2。
终端根据上行状态信息确定待传输上行控制信息的重复次数，有助于终端合理利用资源传输上行控制信息。
终端可以利用下行参考信号进行信道测量，并利用上下行信道互惠性，获取上行信道的状态信息。
应理解，终端确定重复次数时，还可以参考其他终端的信息，本申请对此不作限制。
终端根据待传输上行控制信息的星座点符号数M确定重复次数N，具体可以包括：终端将第一资源包括的子载波数量与M的比值确定为N。第一资源为承载待传输上行控制信息的上行控制信道所使用的资源。
例如，第一资源包括的子载波数量为12，即第一资源包括12个子载波，且待传输上行控制信息的星座点符号数为3个时，可以将12除以3得到的结果4确定为待传输上行控制信息的3个星座点符号的重复次数。
终端自己确定重复次数N时，终端可以向网络设备发送指示信息，该指示信息指示重复次数N，以便于网络设备可以根据该重复次数N接收终端的上行控制信息。
终端从网络设备获取重复次数N，具体可以包括；终端接收网络设备发送的指示信息，该指示信息指示重复次数N；终端根据该指示信息确定重复次数N。
图2所示的通信方法中，不论是终端自己确定的重复次数N，还是网络设备为终端确定的重复次数N，可选地，该终端的上行控制信息的重复次数可以与其他终端的上行控制信息的重复次数不同。
例如，有3个终端复用相同的资源发送各自的上行控制信息。其中，第一个终端的待发送上行控制信息的重复次数可以为2，第二个终端和第三个终端的待发送上行控制信息的重复次数可以为4。此时，第一个终端的正交覆盖码可以为[1,1]，第二个终端的正交覆盖码可以为[1，j，-1，-j]，第三个终端的正交覆盖码可以为[1，-j，-1，j]。
若第一个终端的待发送上行控制信息包括6个QPSK符号，第二个终端和第三个终端的待发送上行控制信息分别包括3个QPSK符号，则这三个终端将各自待发送上行控制信息的QPSK符号重复相应次数后，再乘上相应正交覆盖码后的频域梳状结构图如图5所示。
由图5可知，这三个终端的上行控制信息的重复次数虽然不同，但各自的上行控制信息的梳状结构交错排列，并不会产生冲突。
图6是由网络设备执行的通信方法的示意性流程图。应理解，图6示出了通信方法的步骤或操作，但这些步骤或操作仅是示例，本申请实施例还可以执行其他操作或者图6中的各个操作的变形。此外，图6中的各个步骤可以按照与图6呈现的不同的顺序来执行，并且有可能并非要执行图6中的全部操作。
S610，网络设备接收终端发送的第二数据段，第二数据段为第一终端根据正交覆盖码对第一数据段进行处理得到的，第一数据段为第一终端的上行控制信息重复N次后得到的，N为正整数。
换句话说，网络设备接收的第二数据段可以为S240中终端发送的第二数据段。
网络设备接收第二数据段具体可以包括：接收终端发送的时域数据；对时域数据进行快速傅里叶变换(fast fourier transformation，FFT)变换，取出上行控制资源对应的子载波 上的数据，进行信道均衡；对均衡后的数据进行DFT处理，得到第二数据段。
若终端的重复次数N对应多个正交覆盖码，则网络设备110还可以从这多个正交覆盖码中确定终端120对上行控制信息重复N次后应使用的正交覆盖码。通常情况下，网络设备110可以向终端120发送指示信息，指示重复次数N对应的多个正交覆盖码中的某个正交覆盖码在这多个正交覆盖码中的索引。
如果是多个终端复用相同的资源发送各自的上行控制信息，且每个终端的上行控制信息的重复次数相同，则网络设备110为不同的终端确定的正交覆盖码应尽量不同。这样，可以使得这多个终端的上行控制信息在相同的资源上交错排列，不会相互影响，从而可以提高通信可靠性。
S620，网络设备根据N确定解正交覆盖码。
具体地，网络设备可以根据N以及网络设备上配置的重复次数和正交覆盖码的对应关系，确定N对应的正交覆盖码，然后将该正交覆盖码的共轭确定为解正交覆盖码。
可选的，如果重复次数N对应多个正交覆盖码，网络设备可以根据N以及重复次数和正交覆盖码的对应关系，找到重复次数N对应的多个正交覆盖码；然后根据终端使用的正交覆盖码的索引，从这多个正交覆盖码中确定一个正交覆盖码；最后将该正交覆盖码的共轭确定为解正交覆盖码，
或者，网络设备可以根据N以及网络设备上配置的重复次数和解正交覆盖码的对应关系，确定N对应的解正交覆盖码。
可选的，如果重复次数N对应多个解正交覆盖码，则网络设备从重复次数与解正交覆盖码的对应关系中，找到重复次数N对应的多个解正交覆盖码后，可以根据终端120使用的正交覆盖码的索引，从这多个解正交覆盖码中确定一个解正交覆盖码。
应注意，本申请实施例并不限制S610与S620的执行顺序。
S630，网络设备将解正交覆盖码与第二数据段相乘，得到第一数据段。
具体地，网络设备将S610中得到的第二数据端与S620中得到的解正交覆盖码相乘，得到第一数据段。如可以得到包含12个星座点符号的第一数据段。
S640，网络设备对第一数据段进行N次去重复处理，得到第一终端的上行控制信息。
如N为4，则对包含12个星座点符号的第一数据段进行4次去重，则可以得到3个星座点符号。这3个星座点符号即为上行控制信息的星座点符号。
此后，网络设备可以对去重后的星座点符号进行解调，并对解调得到的数据端进行解码，即可以得到上行控制信息。
图6所示的通信方法中，重复次数N可以是网络设备自己确定的，也可以是从终端获取的。
网络设备自己确定重复次数N时，可以根据终端的上行信道状态信息或上行信道信噪比或这二者确定重复次数。
如，在终端的CSI大于某个阈值时，确定重复次数为8；在终端的信噪比小于某个阈值时，确定重复次数为2。
网络设备根据终端的信息确定终端的上行控制信息的重复次数，有助于终端合理利用资源传输上行控制信息。
应理解，网络设备确定重复次数N时，还可以参考其他终端的信息，如其他终端的 CSI或信噪比或其他终端的重复次数。这样，可以有助于各个终端合理地复用相同的资源传输各自的上行控制信息。
网络设备自己确定重复次数N时，网络设备还可以向终端发送指示信息，指示该重复次数，以便于终端可以根据该重复次数发送上行控制信息。可选地，网络设备可通过系统信息或高层信令等向终端发送该指示信息，或通过下行控制信息(downlink control information，DCI)发送该指示信息。
若重复次数N对应多个正交覆盖码，则网络设备还可以向终端发送该终端应使用的正交覆盖码在重复次数N对应的多个正交覆盖码中的索引，以便于终端可以根据该索引确定正交覆盖码。
网络设备从终端获取重复次数N时，可以包括：网络设备接收终端发送的指示信息，该指示信息指示重复次数N。
图6所示的通信方法中，可选地，网络设备可以为在相同资源上发送上行控制信息的不同的终端确定不同的重复次数，以充分利用资源，提高资源的利用率。
例如，网络设备在某个资源上接收多个终端发送的上行控制信息，其中一个终端的上行控制信息的重复次数为N，一个终端的上行控制信息的重复次数为K，K与N不相等。
