CENTRAL PROCESSING UNIT, AUXILIARY UNIT AND METHOD FOR COMMUNICATION

摘要

A central processing unit for communicating with at least one auxiliary unit, comprising a transmitter unit (12) for the transmission of a series of multi-frames and a processor (14) for generating the series of multi-frames. A multi-frame in the series of multi-frames comprises a control frame and a useful frame. The control frame is provided with sleep mode information for the at least one auxiliary unit. The sleep mode information indicates the period of time in which the at least one auxiliary unit should be in said sleep mode. Said period of time is greater than or equal to the duration of the at least one useful frame of the multi-frame. Auxiliary units can thus be placed in a sleep mode in a deterministic manner and for any desired period of time so as to obtain as low power consumption as possible in said auxiliary unit.
