Abstract

Embodiments relate to methods and apparatuses for performing a random access procedure from a mobile terminal to communicate with a wireless communication network, the random access procedure providing a first (41) and a second group (42) of available random access radio resources, wherein the first and the second group (41; 42) comprise a plurality of random access radio resources assigned to the mobile terminal for sending a random access preamble to the wireless communication network. A sliding resource window (43) is provided to the mobile terminal, the resource window (43) comprising a plurality of consecutive available random access radio resources from at least one of the two groups (41; 42), wherein the mobile terminal may randomly select, from the resource window, one of the available random access radio resources assigned to the mobile terminal for sending the random access preamble, and wherein a start of the sliding resource window depends on an available random access radio resource (44), which is currently valid for uplink random access to the cell of the wireless communication network.
