Zusammenfassung:A user equipment (10) arranged to be comprised in a Long Term Evolution network comprises a receiver configured to receive data from a base station (20) on a radio channel indicating a random access reception power to detect a random access transmission. The user equipment (10) further comprises a transmitter configured to transmit random access data using a random access transmission power, wherein the random access transmission power to be used is based on the received data, a parameter of random access configuration that influences a detection performance of the random access at the base station (20), which parameter comprises a preamble format and/or a basic cyclic shift value of a preamble, a power ramping arranged to increase the random access transmission power based on a transmission attempt number, and also to take into account power path loss between the user equipment (10) and the base station (20).
