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 device for time alignment on a reverse link in a CDMA mobile communication system. A base station stores a reference sync channel RTD (Round Trip Delay), calculates the difference between the reference sync channel RTD and a measured sync channel RTD, and outputs a time alignment control signal on a forward control channel when the calculated RTD error exceeds a predetermined value, during a data communication. A terminal receives the time alignment control signal on the forward control channel and time aligns a reverse traffic channel based on the received time alignment control signal.

摘要： There are provided spread spectrum signal generating devices and methods in a transmitter of a mobile communications system using a plurality of logical channels. In the spread spectrum signal generating devices, a multiplexer time multiplexes a pilot channel signal and a control channel signal which are output at substantially constant power levels. A first orthogonal encoder orthogonally spreads the output of the multiplexer with an orthogonal code. A second orthogonal encoder orthogonally spreads voice channel data of a variable bit rate with an orthogonal code. A third orthogonal encoder orthogonally spreads packet channel data of a variable bit rate with an orthogonal code. An IQ signal mapper adds the outputs of the first and third orthogonal encoders, outputs the added signal as a first channel signal, and outputs the output of the second orthogonal encoder as a second channel signal. A PN spreader spreads the first and second channel signals with PN codes and outputs a final spectrum spread signal, which exhibits a substantially minimized peak-to-average power ratio.
