Patent ID: 7394790

Claim:
A method of detecting ACK/NACK in a mobile terminal comprising a physical layer and higher layers, wherein the higher layers are layers which are higher in protocol layers than the physical layer, the method comprising: receiving and detecting, by the physical layer in the mobile terminal, the ACK/NACK in a downlink channel; delivering ACK/NACK information to the higher layers, wherein, when the mobile terminal is not in soft handover, ACK information is delivered by said delivering if ACK is detected by said detecting, else, NACK information is delivered by said delivering, and wherein, when the mobile terminal is in soft handover, a plurality of ACK/NACKs is received via one or more radio links form different cells in an active set by said receiving, and when a radio link set comprising the one or more radio links comprises a plurality of radio links, said delivering comprises: combining, by the physical layer in the mobile terminal, the plurality of ACK/NACKs received from a same radio link set into a combined ACK/NACK information, when the radio links are in the same radio link set; and delivering the combined ACK/NACK information to the higher layers.
