A method and device for communicating data within a packet frame unit between a terminal and a base station are disclosed. The terminal communicates the packet data to the base station. In response, the base station transmits a channel occupying signal, if the data transmission from the terminal is perceived by the base station. The terminal continues the communication of the packet data, while the channel occupying signal is active, determines whether the base station receives the communicated packet data, and ends the process for communicating the packet data if the base station receives the communicated packet data. If the base station fails to receive the communicated packet data, the terminal is informed through the channel occupying signal. Thereafter, the terminal discontinues its communication and then re-attempts to communicate the packet data from the beginning.

Provided are a method and apparatus for analyzing a circuit model by reducing, and a computer program product for analyzing the circuit model. The circuit model at least includes independent current source models, resistance models, and capacitance models. Also, the circuit model forms a resistance capacitance (RC) network with independent current sources. The method includes selecting a node to be removed using resistance information and comparing conductance of a capacitor for a given time step and the total conductance of the node. Further, the method includes removing the selected nodes and generating RC elements and independent current sources using adjacent nodes, which maintain the accuracy of node voltages of a circuit reduced in an accuracy order used for entrywise perturbation of the corresponding circuit equation. Moreover, an efficient method of handling the independent current sources while reducing the circuit is provided.
