Abstract
Abstract Packet data communicating device and method in a CDMA communication system. According to a first embodiment, a transmitting device for a base station includes a data generator for generating frame data to be transmitted, a first mask generator for generating a long code mask for a forward common channel, a second mask generator for generating a long code mask for a forward common channel to be designated as dedicated to a specific mobile station, a selector for selecting one of the long code masks generated in the first and second mask generators, a long code generator for generating a long code with the selected long code mask, a scrambler for mixing the frame data received from the data generator and the long code received from the long code generator, and a transmitter for spreading the scrambled frame data, for transmission.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A transmitting device for a base station in a mobile communication system, comprising: a common channel data generator for generating a common channel data frame to be transmitted; a first mask for generating a first long code for a forward common channel; a second mask for generating a second long code for a forward common channel to be designated as dedicated to a specific mobile station; a selector for selecting one of the first and second long code masks generated in the first and second mask; a long code generator for generating a long code with the selected long code mask from the selector; a mixer for mixing the frame data received from the data generator and the long code received from the long code generator; and a transmitter for spreading a mixer output for transmission.
Claim 2
Dependent Claim
136 words
A transmitting device for a base station in a mobile communication system, comprising: a common channel data generator for generating a common channel data frame to be transmitted; a first mask for generating a first long code for a forward common channel; a second mask for generating a second long code for a forward common channel to be designated as dedicated to a specific mobile station; a selector for selecting one of the first and second long code masks generated in the first and second mask; a long code generator for generating a long code with the selected long code mask from the selector; a mixer for mixing the frame data received from the data generator and the long code received from the long code generator; and a transmitter for spreading a mixer output for transmission.
Claim 3
Dependent Claim
137 words
A transmitting device for a mobile station in a mobile communication system, comprising: an orthogonal modulator for orthogonally modulating frame data to be transmitted; a first mask for generating a first long code for a reverse common channel; a second mask for generating a second long code for a reverse common channel to be designated as dedicated; a selector for selecting one of the first and second long code masks in the first and second mask; a long code generator for generating a long code with the selected long code mask; a mixer for producing a spreading code by mixing a common PN code with the generated long code; a spreader for multiplying the orthogonally modulated frame data by the spreading code; and a transmitter for upconverting the frequency of the output of the spreader, for transmission.
Claim 4
Dependent Claim
137 words
A transmitting device for a mobile station in a mobile communication system, comprising: an orthogonal modulator for orthogonally modulating frame data to be transmitted; a first mask for generating a first long code for a reverse common channel; a second mask for generating a second long code for a reverse common channel to be designated as dedicated; a selector for selecting one of the first and second long code masks in the first and second mask; a long code generator for generating a long code with the selected long code mask; a mixer for producing a spreading code by mixing a common PN code with the generated long code; a spreader for multiplying the orthogonally modulated frame data by the spreading code; and a transmitter for upconverting the frequency of the output of the spreader, for transmission.
Claim 5
Dependent Claim
60 words
The transmitting device of claim 2 , further comprising: a pilot channel transmitter for spreading a reverse pilot channel signal to be transmitted simultaneously with the common channel message by the spreading code and continuously transmitting the spread reverse pilot channel signal; and wherein said reverse common channel is designated upon a call origination in a dedicated channel released state.
