Patent ID: 7269420

Claim:
A method for transmitting uplink data by a user equipment (UE) in a code division multiple access (CDMA) communication system including a Node B, the UE is located in a region of the Node B, a neighbor Node B being adjacent to the Node B and having a soft handover region where the neighbor Node B overlaps with the Node B, and a radio network controller (RNC) connected to the Node B and the neighbor Node B, the method comprising the steps of: determining whether the UE is located in one of a non-soft handover region of the Node B, and in the soft handover region; transmitting the uplink data to the Node B for a predetermined first transmission time interval, if it is determined that the UE is located in the non-soft handover region; and transmitting the uplink data to the Node B and the neighbor Node B for a predetermined second transmission time interval, if it is determined that the UE is located in the soft handover region.
