A channel structure and mechanisms that support effective and efficient allocation and utilization of the reverse link resources. In one aspect, mechanisms are provided to quickly assign resources (e.g., a supplemental channel) as needed, and to quickly de-assign the resources when not needed or to maintain system stability. The reverse link resources may be quickly assigned and de-assigned via short messages exchanged on control channels on the forward and reverse links. In another aspect, mechanisms are provided to facilitate efficient and reliable data transmission. A reliable acknowledgment/negative acknowledgment scheme and an efficient retransmission scheme are provided. Mechanisms are also provided to control the transmit power and/or data rate of the remote terminals to achieve high performance and avoid instability.

1. A method for transmitting data on a reverse link of a wireless communication system by a remote terminal, comprising: selecting, by the remote terminal, a transmission data rate by comparing a current traffic-to-pilot ratio to one or more threshold levels, the remote terminal selecting a lower data rate if the current traffic-to-pilot ratio is less than a level corresponding to the lower data rate or a higher data rate if the current traffic-to-pilot ratio is greater than a level corresponding to the higher data rate;transmitting a frame of data on the reverse link via a data channel and according to the selected data rate;temporarily retaining the data frame in a buffer;monitoring for a message on a forward link indicating a received status of the transmitted data frame; andprocessing the data frame based on the received message. 2. The method of claim 1, wherein the processing includes; retransmitting the data frame if the message indicates that the transmitted data frame was incorrectly received. 3. The method of claim 1, wherein the processing includes; discarding the data frame from the buffer if the message indicates that the transmitted data frame was correctly received. 4. The method of claim 1, wherein the processing includes; retaining the data frame in the buffer if the message is not properly detected. 5. The method of claim 1, further comprising: monitoring for a second transmission of the message;wherein the processing of the data frame is based on one or more received messages for the data frame. 6. The method of claim 5, further comprising: combining the received messages for the data frame to provide a more reliable message. 7.

The method of claim 1, wherein the current traffic-to-pilot ratio is determined dynamically. 11. The method of claim 1, further comprising: transmitting a second frame of data on the reverse link via the data channel and according to a second data rate, different from the first data rate, that is the other of the lower data rate or the higher data rate based on changes to the current traffic-to-pilot ratio;temporarily retaining the second data frame in the buffer;monitoring for a second message on the forward link indicating a received status of the transmitted second data frame; andprocessing the second data frame based on the received second message. 12.
