Abstract: The present invention relates to a method for transmitting data packets from a mobile terminal to a base station using a hybrid automatic repeat request protocol and soft combining of received data. Further, the present invention provides a base station and a mo-bile terminal both configured to perform the respective method steps. Moreover, a communication system is provided which comprises at least one base station and at least one mobile terminal. In order to decrease the interference caused by retransmissions, the present invention suggests the use of separated channels for initial transmissions and their retransmissions.

Abstract: A drum type washing and drying machine includes a rotary drum provided with drum perforations on the cylindrical surface thereof, a water tub elastically supported in a main body of the machine, for accommodating the rotary drum, a blower unit for circulating air into the rotary drum, a heating unit for heating the air to be circulated into the rotary drum, an air flow passage for directing air, which has been exhausted from the rotary drum into a space between the water tub and the rotary drum through the drum perforations, to the blower unit, a heat exchanging member installed in the air flow passage, and a cooling water supply unit for supplying cooling water to the heat-exchanging member. The heat-exchanging member is slantingly disposed in the air flow passage and has an upper and a lower surface and to form an approximately U-shaped heat exchanging path.
