20100208717 | Apparatus and method for supporting frequency rearrangement in wireless communication system - A base station includes a center frequency setting unit, a local oscillator, a baseband processor, and an RF processor. In the event of a frequency band change, the center frequency setting unit sets a center frequency of a use frequency channel to have a predetermined offset value with respect to a center frequency before the frequency band change. The local oscillator generates an LO frequency signal according to the center frequency set by the center frequency setting unit. The baseband processor generates a downlink baseband signal. The RF processor uses the LO frequency signal to convert the downlink baseband signal into an RF signal prior to transmission. | 08-19-2010 |
20110205985 | DATA TRANSMISSION APPARATUS AND METHOD FOR A HIGH-SPEED PACKET ACCESS SYSTEM - A data transmission method for a high-speed packet access system includes: sending, by a user equipment, packet data containing scheduling information having size information of a packet buffer through an uplink channel to a base station, and sending quality indicator information and acknowledgement information through another uplink channel to the base station; determining, by the base station, the value of a turbo mode flag by comparing amounts of data stored in the packet buffer of the user equipment and a packet buffer of the base station respectively with preset thresholds; and deactivating, by the user equipment when the turbo mode flag of an order message contained in received control data, packet data reception and control data transmission, and redirecting transmit power of a specified transmitter to a packet data transmitter to increase transmit power of the packet data transmitter for faster packet data upload. | 08-25-2011 |
