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: An apparatus for selecting a best serving sector in a code division multiple access (CDMA) communication system. A comparator compares a plurality of signal levels received from a plurality of active sectors with a signal level of a current serving sector to produce a difference. A delta generator is coupled to the comparator that generates a delta credit for each of the plurality of active sectors based on the difference. An accumulator is coupled to the delta generator and accumulates a plurality of delta credits to produce an accumulated total credit. A best sector identifier that is coupled to the accumulator identifies the best serving sector from the accumulated total credit.

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: 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 apparatus and method for adjusting a power control setpoint for a power control mechanism with a first state and a second state in a wireless communication system. The method comprises: determining the state of the power control mechanism; when the state of the power control mechanism is the first state, adjusting the power control setpoint in accordance with a first adjustment scheme; and when the state of the power control mechanism is the second state, adjusting the power control setpoint in accordance with a second adjustment scheme.

Abstract: Systems and techniques for controlling transmission power involve receiving a first to second channel power ratio, receiving a first to second channel power ratio, adjusting the power ratio if a combined power of a plurality of channels exceeds a threshold, the channels including the first and second channels, and computing gain of the first channel as a function of the power ratio. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Abstract: In a disclosed embodiment, signal levels of the active sectors of an access terminal are compared with the signal level of the current serving sector of the access terminal (204). Next, a delta credit is accumulated (206). If a D RC lock bit is available, then an accumulated total credit is authorized to produce an authorized accumulated total credit (208), (210). Afterwards, a n ew serving sector is identified from a pool of candidate sectors based on the signal levels of the active sectors and the authorized accumulated total credits (212).
