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.

What is claimed is: 1. A method for controlling transmit power of a supplemental channel in a reverse link of a wireless communication system, comprising: receiving a first power control stream for controlling the transmit power of the supplemental channel in combination with at least one other reverse link channel; receiving a second power control stream for controlling a transmit characteristic of only the supplemental channel; and adjusting the transmit power and characteristic of the supplemental channel based on the first and second power control streams. 2. The method of claim 1, wherein the second power control stream controls the transmit power of the supplemental channel relative to that of a designated reverse link channel. 3. The method of claim 1, wherein the second power control stream controls a data rate of the supplemental channel. 4. The method of claim 1, wherein the second power control stream enables and disables transmission on the supplemental channel. 5. The method of claim 1, wherein the transmit power of the supplemental channel is adjusted by a larger step size, in response to the second power control stream, than the step size for the first power control stream. 6. The method of claim 1, wherein the second power control stream is assigned to a plurality of remote terminals. 7. The method of claim 6, wherein supplemental channels for the plurality of remote terminals are controlled in similar manner by the second power control stream. 8. A remote terminal for a wireless communication system, comprising: a transmit data processor configurable to process and transmit: data and signaling on a reverse fundamental channel, packet data on an assigned reverse supplemental channel, signaling on a reverse control channel, and information related to a packet data transmission on a reverse indicator channel; a receive data processor configurable to receive a plurality of power control streams on a forward power control channel, the plurality of power control streams including a first power control stream and a second power control stream; and a controller coupled to the transmit and receive data processors and configured to control: a transmit power of the reverse supplemental channel in combination with at least one other reverse link channel based on the first power control stream; and a transmit characteristic of only the reverse supplemental channel based on the second power control stream. 9. The remote terminal of claim 8, wherein the receive data processor is further configurable to receive, on a forward acknowledgment channel, signaling indicative of received status of a packet data transmission on the reverse supplemental channel.
