摘要： A method for performing data communication in a mobile communication system is disclosed. The method serves to increase channel efficiency by connecting and releasing channels in accordance with the presence/absence of control and traffic data transmitted during packet data communications. Transmission power and mobile terminal battery power are conserved by controlling outputs of a dedicated control channel and a pilot channel when data transmission is discontinued temporarily during data communications. The mobile communication system includes an active state in which user data is transmitted through a dedicated traffic channel and control messages are transmitted through a dedicated control channel. In accordance with the method, a transition is made from the active state to a first control hold state when there is no control or user data to transmit for a first preset time. In the first control hold state, the dedicated traffic channel is released while the dedicated control channel and a reverse pilot channel are maintained. A transition is made from the first control state to a second control hold state when there is no user or control data to transmit for a second preset time. In the second control hold state, which is a resource save sub-state, the transmission outputs of the dedicated control channel and reverse pilot channel are interrupted to conserve power.

摘要： In a transmission device and method for a CDMA communication system, when a shorter frame message is generated during transmission of a longer frame message, the transmission of the longer frame message is interrupted, whereupon the shorter frame message is immediately transmitted in place of a portion of the longer frame message. In one embodiment, after the longer frame message is interrupted and the shorter frame message is transmitted, only the tail portion of the longer frame message is transmitted thereafter. That is, the replaced portion of the longer frame message is not transmitted following the shorter frame message transmission. In an alternative embodiment, following the shorter frame message transmission, the remainder of the longer frame message, from the point of interruption, is transmitted in its entirety. In the latter case, the longer frame message is delayed by the length of the shorter frame message.

摘要： A CDMA communication system provides a dedicated control channel capable of efficiently communicating control messages between a base station and a mobile station. In a dedicated control channel transmission device, a controller determines a frame length of a message to be transmitted and outputs a frame select signal corresponding to the determined frame length. A message generator generates frame data of the message to be transmitted according to the frame select signal. A transmitter spreads the frame data and transmitting the spread frame data through a dedicated control channel. In a dedicated control channel reception device, a despreader despreads a received signal. A first message receiver deinterleaves and decodes the despread signal in a first frame length to output a first message, and detects a first CRC corresponding to the decoded signal. A second message receiver deinterleaves and decodes the despread signal in a second frame length to output a second message, and detects a second CRC corresponding to the decoded signal. A controller selects one of the first and second messages according to first and second CRC detection results.

摘要： A method of forming a metal layer on the conductive region of a semiconductor device includes concurrently supplying a mixture gas including a hydrogen gas and a metal chloride compound gas, and a purge gas into a chamber having a sealed space for a predetermined time, thereby forming a first metal layer on the semiconductor substrate, using a plasma enhanced chemical vapor deposition (PECVD) method. The hydrogen gas and metal chloride gases are thereafter alternately supplied for a predetermined time while the purge gas is continuously supplied into the chamber, thereby forming a second metal layer on the first metal layer, using a PECVD method. Deterioration of semiconductor devices due to high heat by a conventional CVD method can be prevented using a PECVD method as a low temperature process, thereby improving a production yield.
