This invention applies to a mobile station that is able to determine a required data rate based on data buffer usage. If the data buffer indicates a requirement for a high data rate transmission, the mobile station sends a request to a base station to be assigned multiple parallel code channels. If the multiple parallel code channels are granted, the mobile station uses the channels for transmitting data to the base station until either the data buffer becomes empty, or a base station time-out occurs, or the mobile station is signalled by the base station to reduce its data transmission rate, whichever occurs first. The mobile station of this invention is enabled to autonomously control the data rate during an assigned period for high speed transmission, so as to lower the data rate when needed for the purpose of improving coverage and/or to avoid operating in a power limited condition, thereby degrading link quality. The data rate is lowered by disabling transmission though at least one parallel code channel, and subsequently resuming transmission though the code channel when conditions warrant. This provides a discontinuous transmission (DTX) mode of operation for individual ones of supplemental parallel data code channels.
