Abstract

An arrangement (17) is provided for setting and adjusting at least one parameter in a radio communication network (11), which is used in control of communication in the radio communication network and which is dependent on a round trip time for a signal travelling from a radio network controller (13) to a user equipment (16) and back to the radio network controller. The arrangement comprises a module (17a) for initially estimating a maximum value of the round trip time; a setting module (17b) for initially setting the parameter depending on the initially estimated maximum value of the round trip time; a module (17c) for measuring the round trip time; and a module (17d) for adjusting the parameter depending on the measured round trip time, wherein the measured round trip time is expected to be shorter than the initially estimated maximum value of the round trip time.
