Abstract
A mobile station transmits sub-packets at a specified transmission rate or an autonomous transmission rate based on a PERSISTENCE bit. The mobile station increments, decrements, or does not change the transmission rate when the PERSISTENCE bit is a second logic state and a rate control bit (RCB) value is a first, a second, or a third value. Another embodiment of the present invention includes an ALL_ACID_IND bit that instructs the mobile station to adjust the specified transmission rate for either a single H-ARQ channel or for all H-ARQ channels. In an alternate embodiment, the mobile station uses the RCB in conjunction with a NAK to adjust a transmission-to-pilot ratio. After the NAK, the mobile station monitors the RCB value to increase the transmission rate, decrease the transmission rate, or not to change the transmission rate of subsequent sub-packets of the same data packet.
