Abstract: An access network that is configured for wireless communication with an access terminal that comprises a flow. The access network comprises means for determining whether the flow is meeting at least one quality of service requirement, means for sending a grant message to the access terminal if the flow is not meeting the at least one quality of service requirement, and means for allowing the flow to autonomously set its own power allocation if the flow is meeting the at least one quality of service requirement. The grant message comprises a current power allocation grant or an accumulated power allocation grant for the flow.

Abstract: Methods and apparatus for estimating maximum rate of data and for estimating a transmission power required for transmission of a data with a rate of data in a communication system are disclosed. A terminal determines a quality metric of a communication link, over which data are to be transmitted, and modifies the determined quality metric by a quality metric margin. The terminal then estimates the maximum rate of data in accordance with the modified quality metric. Alternatively, the terminal then estimates transmission power required for transmission of a data with a rate of data in accordance with the rate of data and the modified quality metric. The quality metric margin may be pre-determined or dynamically adjusted. The terminal dynamically adjusts the quality metric margin in accordance with a result of comparison of a transmit power corresponding to the estimated maximum rate of data with an actual transmit power used to transmit the data.

Abstract: A method and an apparatus for rate control in a high data rate (HDR) communication system are disclosed. An exemplary HDR communication system defines a set of data rates, at which an access point (AP) may send data packets to an access terminal (AT). The data rate is selected to maintain targeted packet error rate (PER). The AT's open loop algorithm measures received signal to interference and noise ratio (SINR) at regular intervals, and uses the information to predict an average SINR over the next packet duration. The AT's closed loop algorithm measures a packet error rate (PER) of the received signal, and uses the PER to calculate a closed loop correction factor. The loop correction factor is added to the SINR value predicted by the open loop, resulting in an adjusted SINR.

Abstract: A method for wireless communication, comprising: receiving data in multiple forward link timeslots; determining a quality metric of the received data; requesting retransmission of the data via a first request scheme if the quality metric indicates the data has not been received correctly; and if retransmission is requested and the data is not received correctly, requesting retransmission of the data via a second request scheme.

Abstract: In a high data rate communication system capable of variable rate transmission, an open loop rate control can be adjusted with a closed loop rate control to maximize throughput. An access point generates interleaved multi-slot packets that allow an access terminal to transmit indicator messages to the access point in accordance with recently received data carried within slots of the multi-slot packets.

Abstract: Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. In one embodiment, the maximum data rates are adjusted as a function of the FL Signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. In still another embodiment, the maximum data rates are adjusted as a function of differences in riseover-thermal values between neighboring sectors.

Abstract: In a multiple-access network, network access terminals (106) can communicate with network infrastructure access nodes (104), or conduct peer-to-peer communications (110). The access terminals are adapted to adjust the transmit power level in response to power control commands received from the access nodes and from other access terminals.
