    摘要: A multiple antenna wireless communication system using a DPD power amplifier and a method for controlling an amplitude of an input signal for a plurality of transmission paths of the DPD power amplifier are provided. The system includes a plurality of amplifiers, a plurality of couplers, a switch, a shared feedback path and a plurality of processors. The plurality of amplifiers amplifies an input signal directed to each of the transmission paths. The plurality of couplers couple amplified signals on respective transmission paths. The switch outputs at least one of the amplified signals coupled on the respective transmission paths. The shared feedback path provides the amplified signal output from the switch to a plurality of processors. The plurality of processors compare a feedback signal provided through the shared feedback path with the input signal and pre-distort the input signal such that the input signal and the amplified signal have a linear relation with each other.

    摘要: A method and apparatus for minimizing data forwarding between Evolved Node Bs (ENBs) during a handover. A User Equipment (UE) sends a status report to an ENB of a source cell immediately before the handover occurs. In this manner, a target cell avoids retransmission of the RLC PDUs, which were successfully transmitted but have not yet been ACKnowledged (ACKed) by the UE, thereby minimizing the amount of data being forwarded from the ENB of the source cell to an ENB of the target cell.

    摘要: A method for transmitting information in a mobile communication system using HSDPA (High Speed Downlink Packet Access) service. When an RNC (Radio Network Controller) generates or changes HSDPA service-related information, it transmits the generated or changed information to a Node B and a UE along with an indicator indicating the change in the HSDPA service information. Therefore, the Node B and the UE simultaneously operate by receiving the generated or changed information, resulting in an increase in the HSDPA service efficiency.
