PREAMBLE SETS MATCHED TO UPLINK TRANSMISSION CONDITIONS

Abstract

The present disclosure relates to random access in wireless communication systems and in particular to transmitting receiving and detecting preamble sequences. A method in a wireless device for transmitting a preamble sequence to a network node is disclosed. The method comprises configuring (S12) a number of preamble sequences into two or more preamble sets wherein each preamble set is associated with at least one respective uplink transmission condition; determining (S13) a transmission condition of an uplink from the wireless device to the network node; and selecting (S14) one out of the two or more preamble sets based on the determined transmission condition to be a selected preamble set and a preamble sequence from the selected preamble set to be a selected preamble sequence; as well as transmitting (S15) the selected preamble sequence on the uplink.
