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: An access terminal (206) is configured for wireless communication with an access network (204) within a sector (1032). The access terminal (206) includes a transmitter (2608) for transmitting a reverse traffic channel to the access network (204), an antenna (2614) for receiving signals from the access network (204), a processor (2602) and memory (2604) in electronic communication with the processor (2602). Instructions are stored in the memo ry (2604). The instructions are arranged to estimate a current value of a rever se activity bit (1444) transmitted by the access network (204). Per flow power allocation may be decreased on increased based on an estimated current value of the reverse activity bit.

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: A method and an apparatus for adaptive data rate selection 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 transmit data packets to an access terminal (AT). The transmission data rate is selected to maintain target packet error rate (PER). Each AT monitors signal quality metric of signals received from APs. An AT receiving forward link signals from multiple ATs identifies the AT associated with the highest quality forward link signal.

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 method for packet data transmission from at least one Access Point to an Access Terminal, data request messages are received from a plurality of Access Terminals. A transmission of data from the Access Terminal having the highest ratio of requested data rate to average served rate is scheduled, and an Access Point transmits data at a randomly varying transmit power, or at a transmit power in synchronism with neighbouring Access Points, in accordance with the data request message.

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.
