Abstract
A method in a first communication device (10) within a long term evolution communication network (Long Term Evolution) to calculate a random access transmission power to be used by the first communication device (10), which It comprises the steps of: - receiving (42) data from a second communication device (20) through a radio channel indicating a target reception power required for random access, characterized in that the method further comprises: - determining (44) a desired random access reception power level of the second communication device (20) based on the received data and a random access configuration parameter that influences a random access detection performance in the second device ( 20) of communication, whose parameter comprises a preamble format and / or a basic cyclic offset value of a preamble, and - calc ular (46) a random access transmission power to be used based on the desired random access reception power level and a power ramp that increases the random access transmission power based on a number of transmission attempts, and also taking into account the loss of power in the path between the first communication device (10) and the second communication device (20).
