摘要： A method and apparatus improve the performance of a carrier amplifier in a Doherty amplifier. The Doherty amplifier includes a power divider, a carrier amplifier, at least one peaking amplifier, offset lines, and a Doherty circuit. The power divider provides a power signal to each of the carrier amplifier and the at least one peaking amplifier. The carrier amplifier amplifies power of a signal inputted from the power divider. The at least one peaking amplifier amplifies power of a signal inputted from the power divider. The offset lines control a load impedance when the at least one peaking amplifier does not operate. When the at least one peaking amplifier does not operate, the Doherty circuit generates the load impedance of the carrier amplifier that is larger than twice a load impedance at the maximum output power of the carrier amplifier.

摘要： An apparatus and method for compensating Quality of Service (QoS) during a handover of a Mobile Station (MS) by a serving Base Station (BS) and a target BS in a wireless broadband access system are provided. The method includes generating a message during a handover from the serving BS to a target BS, the message including at least one of a data transmission/reception time just before the handover, a size of a time window for which a data transmission/reception history is recorded in an accumulated way, and an amount of data transmitted/received during the time window, and transmitting the message to the target BS. The target BS can more accurately find a handover break time and the amount of data transmission/reception in the serving BS at the time the MS has been handed over to the target BS, enabling fast and adequate QoS compensation/correction for each QoS class, and thus facilitating flexible, efficient and accurate QoS provisioning regardless of controlled handover and uncontrolled handover.

摘要： A method and apparatus for managing a buffer of a Radio Access Station (RAS) in a communication system are provided. An available buffer space determiner sets a threshold for each service class for scheduling packet input/output of the buffer according to priority of a service class, estimates and stores, upon receipt of a packet at the buffer, an available space size of the buffer after the packet reception, compares the estimated available space size of the buffer with a first threshold corresponding to a first service class indicative of a service class of the packet, and schedules packet input/output of the buffer according to the comparison result. A processor module schedules packet input/output of the buffer according to an output of the available buffer space determiner. The present invention can improve quality of services through service differentiation based on priorities of service classes and buffer management based on characteristics of the corresponding service traffics.
