A scheduler (105) for scheduling data packets over an air interface of a cellular communication system comprises a coherence time processor (213) which determines a coherence time for a user equipment (101, 103). A scheduling unit (205) then schedules at least a first data packet for the user equipment (101, 103) in response to the coherence time. In some embodiments, the system may use a retransmission scheme and a scheduling which depends on a time varying propagation characteristic. In such embodiments, an available delay may be allocated to retransmissions or propagation dependent scheduling dependent on the coherence time. The scheduler may e.g. be implemented in a base station. |
