Patent ID: 7215974

Claim:
A wireless communication system utilizing transmission power control in which user data is processed as a multirate signal having a rate N(t) where N(t) is a function time, in which the user data signal having rate N(t) is converted into a transmission data signal having a faster rate M(t) for transmission and in which the transmission power is adjusted by applying a scale factor in response to step up/down data, comprising: at least one user equipment (UE) that includes a UE transmitter having: a processor which computes a scale factor as a function of N(t)/M(t), a data signal rate converter which converts user data signals having rate N(t) into transmission data signals having a faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in transmission data signals which it transmits, and a combiner which combines the computed scale factor with the transmission data signals for transmission by the UE; and at least one base station including a base station transmitter having: a processor which computes a scale factor as a function of N(t)/M(t), a data signal rate converter which converts user data signals having rate N(t) into transmission data signals having a faster rate M(t) by repeating selected data bits whereby the energy per bit to noise spectrum density ratio is increased in transmission data signals which it transmits, and a combiner which combines the computed scale factor with the transmission data signals for transmission by the base station.
