Abstract: A multi-subscriber identification module (multi-SIM) device includes plural SIMs, plural radio frequency (RF) resources, and a baseband processor. The plural RF resources are assigned to the plural SIMs, a first portion of the RF resources supporting use of a non-limited channel configuration and a second portion of the RF resources supporting use of a limited channel configuration according to a radio resource control (RRC) protocol.

Abstract: 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.

Abstract: An apparatus and method for receiving data when an HS-SCCH is not used in a mobile communication system are provided. In the apparatus and method, retransmission data is received, parameters including information about initial transmission data are acquired from the retransmission data, the initial transmission data is retrieved from a second-rate dematching input buffer based on the information about the initial transmission data, second-rate dematching is performed on the initial transmission data and the retransmission data, and first output data is generated by soft-combining the second rate-dematched initial transmission data with the second rate-dematched retransmission data. Accordingly, memory usage can be reduced.

Abstract: There is provided a channel estimation apparatus for estimating a radio channel environment by multiplying a currently received bit signal of a pilot signal and previously received bit signals by weights, and summing the weighted currently received bit signal and the weighted previously received bit signals in a CDMA mobile communication system receiving the pilot signal comprised of a stream of bits having given bit values, and a power control signal comprised of power control bits. In the channel estimation, a predictor predicts a next bit signal succeeding the currently received bit signal, multiplies the predicted next bit signal by a weight, and generates a weighted next bit signal. A summer sums the weighted next bit signal from the predictor, the weighted currently received bit signal and the previously received bit signals.
