Abstract: A system (100) and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. A control and transceiver system (1400) configured for determining a data rate control (DRC) value and for transmission a maximum number of time slots allowed for transmission of a physical layer packet of data (510). After detecting a normal termination of transmission, the decoding thresholds (401, 402) are adjusted for decoding a positive acknowledgment message, and repeating decoding of acknowledgement channel (340) with the adjusted thresholds (401, 402). Retransmitting the physical layer packet of data at least one more time after based on whether the repeat of decoding of the acknowledgment channel (340) produces a negative acknowledgment message. The retransmission may be conditioned upon a throughput level of communications between the base station and the mobile station.

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: An Access Terminal can send a first set of slots of a first packet to an Access Network, wherein the first set of slots is a subset of a plurality of slots of the first packet and includes one or more slots. Then, the Access Terminal can gate off for a predetermined period of time after sending the first set of slots of the first packet and before sending a next set of slots, wherein the predetermined period of time is determined by the number of slots in the first set of slots of the first packet. Finally, the Access Terminal can determine the next set of slots to send based on whether an ACK or a NAK corresponding to successful or unsuccessful decoding, respectively, of the first set of slots of the first packet has been received from the Access Network and send the next set of slots after the predetermined period of time.

Abstract: Un procedimiento de solicitud de repetición automática para un enlace inverso de un sistema de comunicación inalámbrica de acceso múltiple por división de código de paquetes de datos de alta velocidad, comprendiendo el procedimiento, en una red de acceso: recibir (302) un primer conjunto de ranuras de un primer paquete desde un terminal de acceso (102), en el que el primer paquete incluye el primer conjunto de ranuras y un segundo conjunto de ranuras; recibir (304) un primer conjunto de ranuras de un segundo paquete desde el terminal de acceso (102) inmediatamente después de recibir el primer conjunto de ranuras del primer paquete; intentar (306) decodificar el primer conjunto de ranuras recibido del primer paquete; determinar (308) si el primer conjunto recibido de ranuras del primer paquete se ha decodificado con éxito; cuando la decodificación del primer conjunto de ranuras recibido del primer paquete tiene éxito, enviar (310) un ACK al terminal de acceso (102) y recibir (312) un primer conjunto de ranuras de un tercer paquete al enviar (310) el ACK; cuando la decodificación del primer conjunto de ranuras recibido del primer paquete no tiene éxito, enviar (314) un NAK al terminal de acceso (102) y recibir (316) un segundo conjunto de ranuras del primer paquete desde el terminal de acceso (102) al enviar (314) el NAK, e intentar (318) decodificar una combinación del primer conjunto de ranuras recibido del primer paquete y del segundo conjunto de ranuras recibido del primer paquete; y en el que el ACK y el NAK, respectivamente, se envían en un canal ACK de enlace directo modulado por desplazamiento de fase binaria, en el que el ACK o el NAK se envía en una fase ortogonal a la fase de un bit de control de potencia de enlace inverso enviado en un canal de control de potencia de enlace inverso.

Abstract: Procedimiento para incrementar la capacidad de transmisión de datos de una red de comunicaciones, comprendiendo las etapas de: generar una pluralidad de segmentos de datos y una pluralidad de segmentos huecos en 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 donde los segmentos huecos no transportan ningún dato; transmitir la pluralidad de paquetes (100, 200, 300, 400, 500) a un terminal de acceso (701), y recibir al menos un mensaje indicador transmitido por el terminal de acceso durante periodos asociados a los segmentos huecos en el punto de acceso (700), indicando el mensaje indicador un estado de recepción de la pluralidad de paquetes (100, 200, 300, 400, 500) recibidos en el terminal de acceso (701).

Abstract: In a high data rate communication system, a method and apparatus for improved throughput while transmitting data packets within multiple time slots. In order to avoid unnecessary retransmissions of a packet, a subscriber station sends a Stop-Repeat signal to a base station, causing the base station to cease further transmissions of the packet. In order to enable successful decoding of a packet, a subscriber station sends a Continue-Repeat signal to a base station, causing the base station to send retransmissions of the packet during time slots beyond a predetermined default number of time slots.

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.
