1. A method comprising:
receiving, by an apparatus from a network device, a first signaling indicating a length K sequence;
transmitting, by the apparatus to the network device a reference signal;
wherein the reference signal is obtained from the length K sequence, and the length K sequence is obtained by a cyclicly repeated length p ZC sequence, where p is a prime number larger than K/2 and where p is also smaller than a largest prime number that is smaller than K,
wherein the reference signal is obtained from the length K sequence by:
applying, by the apparatus, pre-coding to the length K sequence to produce a pre-coded sequence;
generating, by the apparatus, a first pulse shaped frequency domain sequence by applying first frequency domain spectral shaping to the pre-coded sequence.
