Abstract

The present invention aims to solve the problem that the preamble ramping process on a random access channel (RACH) of a 3rd generation telecommunication network can take a considerable time and, as a consequence, cause significant delays in RRC signalling and user data transmission on RACH. The present invention suggests to base the calculation of the initial preamble power value on the last performed RACH transmission instead of calculating the initial preamble power from the information that is broadcasted in the system information. This results in fewer preamble rampings until the preamble is detected in the Node-B.
