    Abstract: "equipamento para retransmitir sinais em um sistema de comunicação". um terminal transmissor, transmite sinais em uma forma de pacote para um terminal receptor, se o pacote for destinado ao terminal receptor, se for esse o caso, o terminal receptor demodula o pacote. o terminal receptor então computa uma métrica de qualidade do pacote, e compara a métrica de qualidade computada com uma métrica de qualidade contida no pacote. se as métricas de qualidade coincidirem, o pacote é enviado para processamento adicional. se as métricas de qualidade falharem em coincidir, o terminal receptor envia uma solicitação para a retransmissão do pacote. o terminal transmissor determina qual pacote precisa ser retransmitido com base na solicitação de retransmissão. se a entrega do pacote de acordo com uma descrição supra citada falhar, a retransmissão de acordo com os esquemas baseados em número de seqüência convencionais, por exemplo, protocolo de link rádio, é tentada.

    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: METHOD AND APPARATUS FOR ESTIMATING A MAXIMUM RATE OFDATA AND FOR ESTIMATING POWER REQUIRED FOR TRANSMISSIONOF DATA AT A RATE OF DATA IN A COMMUNICATION SYSTEMMethods and apparatus for estimating a transmission power required fortransmission of data and detecting an outage in a communication system are disclosed. Aterminal determines a quality metric of a communication link, over which data are to betransmitted, and modifies the determined quality metric by a quality metric margin. Theterminal may declare an outage event when power required for transmission of areference signal exceeds power required for transmission of the reference signaldetermined form the modified quality metric. Alternatively, the terminal may estimatetransmission power required for transmission of data in accordance with the modifiedquality metric. The quality metric margin may be a pre-determined or dynamicallyadjusted.Figure 6

    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.
