Patent ID: 7929498

Claim:
A transmission circuit configured to spread code a first data and a second data in accordance with two different corresponding spreading codes, a first spreading code and a second spreading code; the transmission circuit further being configured to output the spread first data using a first spreading code on a first channel and spread second data using a second spreading code on a second channel, respectively, the first channel derived from the first data using the first spreading code at a first data rate, and the second channel derived from the second data using the second spreading code at a second data rate, the first and second data rates being different from one another, wherein the transmission circuit is further configured to output a third channel, which does not carry the first and second data, the third channel derived by spread coding a power control bit and signaling information with a corresponding spreading code, the signaling information facilitating the processing of radio frequency signals by a base station, wherein the transmission circuit is further configured to combine the first channel, the second channel and the third channel; and an antenna coupled to the transmission circuit, the antenna outputting a radio frequency signal derived from the combined the first, the second and the third channels; wherein the first channel, the second channel and the third channel are transmitted at the same time, wherein the transmission circuit is further configured to determine the power control bit based on a power level of a channel received by the antenna and an interference or a noise level associated with the received channel.
