Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
81 words
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.
Claim 2
Independent Claim
81 words
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.
Claim 3
Dependent Claim
29 words
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.
Claim 4
Dependent Claim
20 words
The method of claim 1 , wherein the second power control stream controls a data rate of the supplemental channel.
Claim 5
Dependent Claim
20 words
The method of claim 1 , wherein the second power control stream enables and disables transmission on the supplemental channel.
Claim 6
Dependent Claim
39 words
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.
Claim 7
Dependent Claim
20 words
The method of claim 1 , wherein the second power control stream is assigned to a plurality of remote terminals.
Claim 8
Dependent Claim
26 words
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.
Claim 9
Dependent Claim
147 words
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.
Claim 10
Dependent Claim
147 words
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.
Claim 11
Dependent Claim
37 words
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.
