背景技术
第四代移动通信技术(4G,the 4th Generation mobile communication technology)长期演进(LTE,Long-Term Evolution)/高级长期演进(LTE-Advance/LTE-A,Long-Term Evolution Advance)和第五代移动通信技术(5G,the 5th Generation mobile communication technology)所面临的需求越来越多。从目前发展趋势来看,4G和5G系统都在研究支持增强移动宽带、超高可靠性、超低时延传输、海量连接的特征。
在新一代空口(NR:New Radio)技术中,在物理上行业务信道的传输中,支持梳状传输,也就是传输的时候,数据只占用分配的带宽的奇数或偶数的子载波上,当数据信道分配的带宽为1个资源块(Resource Block,简称RB,频域上对应12个子载波)或3个资源块时,当采用梳状传输时,参考信号所使用的序列长度为6和18。此外,短的物理上行控制信道(short PUCCH)已经同意了采用基于序列的形式来携带最多两比特的控制信息。由于短PUCCH持续的时间较短,对相应的序列设计提出了新的要求。因此, 针对序列长度为6,12,18和24的新的序列设计,至少用于基于短的物理上行控制信道发送上行控制信息以及基于梳状的物理上行共享信道的参考信号,成为一个亟待解决的问题。

Figure PCTCN2018116280-appb-000079
序列的峰均功率比根据以下公式计算:

方法1:xcorr_coeffs=abs(NFFT*IFFT(seq1.*conj(seq2),NFFT)/length(seq1))

其中NFFT表示(I)FFT操作的点数,conj表示共轭,length表示长度,seq1和seq2为两条在频域的序列,abs表示绝对值,sum表示求和。

Figure PCTCN2018116280-appb-000085
其中CM采用的上述第二个CM计算公式计算所得,互相关采用的是上述第一个互相关计算公式所得,N_FFT=32M,M为序列长度。
采用表中的序列或者其子集作为参考信号或者直接上行信息,具有立方度量小、功放效率高成优点,特别的,当相邻小区采用的序列索引不同时,还具有降低小区间干扰,提高系统整体性能的效果。
