Abstract
A base station as presented herein improves random access. The base station comprises a radio unit comprising a transceiver and an antenna; a message receiver arranged to receive random access preamble messages with a preamble, from mobile communication terminals, on a random access channel; a distance determiner arranged to, for each random access preamble message, determine whether the corresponding mobile communication terminal is further away than an outer threshold distance from the radio unit; and a radius adjuster arranged to, when it is determined that there is more than a threshold magnitude of mobile communication terminals being further away than the outer threshold distance, increase the outer threshold distance and a random access cell radius of the radio unit. In other words, when many mobile communication terminals are determined to be far away, the random access cell radius is increased, allowing dynamic resizing of the random access cell.
