Abstract
Methods, systems, and devices for generating preambles in mobile communication technology are described. An exemplary method for wireless communication includes transmitting, by a network node, a configuration for random access comprising a value indicative of a number of Zadoff-Chu (ZC) sequence roots (M) and a number of repetitions (N), and receiving, from a wireless device, a random access preamble, wherein the random access preamble comprises M concatenated ZC sequences with different roots, and wherein each of the M concatenated ZC sequences is repeated based on N.

A method for wireless communication comprising:
- transmitting, by a network node, a configuration for random access comprising a value indicative of a number of Zadoff-Chu (ZC) sequence roots (M) and a number of repetitions (N);
- and
- receiving, from a wireless device, a random access preamble,
- wherein the random access preamble comprises M concatenated ZC sequences with different roots, and wherein each of the M concatenated ZC sequences is repeated based on N.
A method for wireless communication, comprising:
- receiving, from a network node, a configuration for random access comprising a value indicative of a number of Zadoff-Chu (ZC) sequence roots (M) and a number of repetitions (N);
- and
- transmitting, by a wireless device, a random access preamble,
- wherein the random access preamble comprises M concatenated ZC sequences with different roots, and wherein each of the M concatenated ZC sequences is repeated based on N.
