    Abstract: A transmitting terminal, transmits signals in a form of packets to a receiving terminal, if the packet was intended for the receiving terminal, if so, the receiving terminal demodulates the packet. The receiving terminal then computes a quality metric of the packet, and compares the computed quality metric with a quality metric contained in the packet. If the quality metrics match, the packet is forwarded for further processing. If the quality metrics fail to match, the receiving terminal sends a request for retransmission of the packet. The transmitting terminal determines which packet needs to be retransmitted based on the request for retransmission. If delivery of the packet in accordance with the aforementioned description fails, retransmission in accordance with conventional sequence-number-based schemes, e.g., radio link protocol, is attempted.

    Abstract: Procedimiento para el incremento de la capacidad de transmisión de datos de una red de comunicaciones, que comprende las etapas de: recibir una pluralidad de segmentos de datos y una pluralidad de segmentos huecos que no transportan datos desde un punto de acceso (700), donde la pluralidad de segmentos de datos están intercalados con la pluralidad de segmentos huecos para formar una pluralidad de paquetes (100, 200, 300, 400, 500); y detectar la pluralidad de paquetes (100, 200, 300, 400, 500) en un terminal de acceso (701), donde el terminal de acceso transmite por lo menos un mensaje indicador a un punto de acceso (700) indicando un estado de recepción determinado por el terminal de acceso durante la duración de un segmento hueco.

    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: 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 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: Cooperative Autonomous And Scheduled Resource Allocation For A Distributed Communication System An access terminal (206) configured for wireless communication with an access network (204) with 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 form the access network (204), a processor (2602) and memory (2604) in electronic communication with the processor (2602). Instructions stored in the memory (2604) implement a method of determining whether a current power allocation grant (1374) for a flow (1216) on the access terminal (206) has been received from the access network (204). If the current power allocation grant (1374) is still active, a current power allocation (1338a) for the flow is set equal to the current power allocation grant (1374). If the current power allocation grant (1374) has not been received, the current power allocation (1338a) for the flow is determined. Figure 13
