Abstract

The present invention relates to a user terminal, UE, in a wireless communication system (). The user terminal () comprises a receiver unit (), a transmitter unit () configured to transmit data in transmit sub-frames occurring at defined sub-frame intervals, and a control unit () configured to control the receiver circuit () and the transmitter circuit (). The control unit () is also configured to create a PRACH, Physical Random-Access Channel, preamble () as an uplink transmission to a node () that is arranged to receive communication from the user terminal in said sub-frames. This communication comprises OFDM, Orthogonal Frequency-Division Multiplexing, based symbols (). The control unit () is configured to create each PRACH preamble () such that is comprises a sequence of a plurality of identical random access sequences (s(n)), where each random access sequence (s(n)) has the same length in time as each one of the OFDM based symbols (). The present invention also relates to a corresponding method.
