Abstract
A method for adapting at least one parameter of a communication system between two subscribers, wherein at least one subscriber is mobile, in which case a current position of the mobile subscriber is determined at a time and a channel quality for a future time is estimated on the basis of the current position using an environmental model, wherein at least one parameter is changed at the future time on the basis of the estimation. Also disclosed is an apparatus.

A method for adapting at least one parameter of a communication system between two subscribers, wherein at least one of the two subscribers is mobile, the method comprising:
- determining a current position of the mobile subscriber at a time t0,
- estimating a channel quality for a future time t1, t2 based on the current position using an environmental model;
- changing at least one parameter at the future time t1, t2 based on the estimation;
- determining speed of the at least one mobile subscriber;
- determining a motion vector using the current position and the speed;
- and
- using the motion vector to estimate a position of the mobile subscriber at the time t1 of the parameter change,
- wherein, to determine the channel quality, a position and a motion vector of further mobile subscribers within a communication range between the two subscribers are additionally taken into account.
An apparatus for adapting at least one parameter of a communication system between two subscribers, wherein at least one parameter is changed based on an estimated future channel quality, wherein at least one current position of at least one mobile subscriber of the two subscribers at a time t0 is detected or determined and the channel quality for a future time t1, t2 is estimated using the current position and an environmental model, wherein at least one parameter is changed at the time t1, t2 based on the estimation, speed of the at least one mobile subscriber is determined, a motion vector is determined using the current position and the speed and is used to estimate a position of the mobile subscriber at the time t1 of the parameter change, and wherein the channel quality is determined while taking into account a position and a motion vector of further mobile subscribers within a communication range between the two subscribers.
