Title:
METHOD FOR TRANSMITTING A REFERENCE SIGNAL HAVING A LOW PEAK TO AVERAGE POWER RATIO
Document Type and Number:
WIPO Patent Application WO/2018/149276
Kind Code:
A1
Abstract:
Aspects of the description provide a method and devices to allow frequency domain spectral shaping (FDSS) to be used on both a reference sequence and data to enable low PAPR. Being able to use FDSS on both the reference sequence and data allows the FDSS to be transparent to the receiver. The method comprises obtaining a first sequence, wherein the first sequence is a base sequence of a set of base sequences, the set of base sequences comprising sub group base sequences, the first sequence obtained by cyclically repeating the sub group sequences at least once; and transmitting, by the device, a reference signal based on the first sequence.
