Abstract

A base station is configured to control a wireless communications network cell of a wireless communications network. The base station is configured to establish a connection to a first user equipment and to a second user equipment using a random access process. For establishing the connection to the first user equipment, the base station is configured to use a sequence of a first random access preamble, the sequence having a first length. For establishing the connection of the second user equipment, the base station is configured to use a sequence of a second random access preamble, the sequence having a second length.
