    • In a direct spreading comb-like spectrum communication method of complementary series repetition modulation type, a set of N (N is an integer of 2 or more) self-complementary series is allotted to each user, one of the N self-complementary series is repeated plural times to convert it to a signal having N comb-like frequency spectra which do not overlap with one another, and N complementary series in relation to the self-complementary series are allotted to the N comb-like spectra, thus generating a transmission signal. Therefore, a CDMA communication method is realized in which by reducing to zero the mutual correlation characteristic representing the signal inputted to the station concerned and transmitted to another station, the distant-near problem is solved, the transmission power level control of the transmitter is dispensed with, the system configuration is simplified, and a multipath signal is easily separated.
    • 在互补串联重复调制类型的直接扩展梳状频谱通信方法中,将N(N为2以上的整数)自补偿序列的集合分配给每个用户,N个自互补序列之一为 重复多次以将其转换为具有不相互重叠的N个梳状频谱的信号,并且将相对于自互补序列的N个互补序列分配给N个梳状光谱,从而产生传输 信号。 因此,通过将表示输入到相关站的信号的相互关联特性减少为零并发送到另一个站的CDMA通信方法被实现,解决了遥远的问题,发射机的发射功率电平控制被分配 简化了系统配置,容易分离多路信号。

    • The disclosure is related to a method of transmitting a physical uplink control channel (PUCCH) in unlicensed spectrum, which is transmitted by a user equipment, the method comprising: - generating a PUCCH format 0 in an interlaced structure, based on a base sequence (BSEQ), an acknowledgment information (A/N), and a cyclic shift group (CSG) containing a number of cyclic shift members (CSM) corresponding to the resource block number within the interlaced structure, - determining the cyclic shift group (CSG) containing a first cyclic shift member (CSMf) and a plurality of subsequent cyclic shift members (CSMn), each cyclic shift member (CSM) being defined by a value and a position, by: - configuring the first cyclic shift member (CSMf) with a first indication related to the CSMf value and a second indication related to the CSMf position; - deriving the plurality of subsequent cyclic shift members (CSMn) based on the CSMf value and on the relative position between CSMf and each CSMn so as to define all CSM which are mutually different; - defining a one-to one mapping relationship between CSG and an acknowledgment information (A/N); - transmitting the generated PUCCH using format 0.
