Abstract: In the data transmission method of an HSDPA system according to the present invention, a transmitter transmits Data Blocks each composed of one or more data units originated from a same logical channel, and a receiver receives the Data Block through a HS-DSCH and distributes the Data Block to a predetermined reordering buffer. Since each Data Block is composed of the MAC-d PDUs originated from the same logical channel, it is possible to monitor the in-sequence delivery of the data units, resulting in reduction of undesirable queuing delay caused by logical channel multiplexing.

Abstract: A packet data transmission method of the HSDPA system includes collecting information on the quality of physical channels, a status of the MAC buffer, the priority level of data, the delay of data, and the like, determining the transmission order of data and the size of a data block to be transmitted based on the collected information, and transmitting the data block through the physical layer according to the order of transmissions. Since the HSDPA scheduler takes into account the delay of data, the quality of real-time services can be improved.

Abstract: A video decoder organizes and stores pixel lines of a reference picture into first and second memory devices. The video decoder then reads portions of a pixel block from the first and second memory devices and processes such a pixel block for generating a subsequent picture. By reading from the first and second memory device with time overlap, latency is minimized for faster video decoding.

Abstract: Disclosed are a method and a device for offering a packet data service during a handover of a user terminal from one radio network controller to another. To avoid the loss of data during SRNS relocation, there is provided a method for checking the validity of the next expected receive PDCP sequence number sent from a receiver PDCP layer with the send PDCP sequence number of the first transmitted but not yet acknowledged PDCP SDU and the send PDCP sequence number first unsent PDCP SDU of the sender PDCP layer. A PDCP protocol structure is reconstructed to support a lossless SRNS relocation in the packet service domain, and control information and operational procedure therefore are newly defined. As a result, the lossless SRNS relocation is achieved in the packet service domain and the mobility of data communication is ensured.
