Abstract

It is described a method of operating a base station and a base station which uses a communication channel depending on channel state related information and time information e.g. a prediction time. In this way, problems due to outdating of the channel state related information may be overcome and a feedback overhead may be reduced. According to other embodiments, other parameters like a used prediction method, a prediction horizon, etc. are used to provide a better scenario adaption. Other embodiments relate to combined long term prediction and short term prediction and respective timing settings. Other embodiments relate to a method of operating a user equipment and a user equipment which is adapted for communicating the required time information between the base station and the user equipment.
