Abstract

"MéTODO E APARELHO DE FORNECIMENTO DE INFORMAçõES DE CONTROLE DE POTêNCIA INDIVIDUAIS EM UMA REDE DE áREA LOCAL SEM FIO E REDE DE áREA AMPLA SEM FIO (WLAN/WWAN)". Método e aparelho empregado por componentes de rede sem fio, tais como pontos de acesso (APs) para controlar o nível de potência de transmissão de unidades de transmissão e recepção sem fio (WTRUs) individuais, por meio do estabelecimento de nível de potência de transmissão com base em transmissões anteriores e recebimento de estatísticas de transmissão e recepção tais como relação sinal-ruído (SNR), taxa de erros de bits (BER), taxa de erros de quadros (FER) e/ou similares. As informações de nível de potência de transmissão são preferencialmente comunicadas por meio de qualquer dentre quadro livre para envio (CTS), solicitação de envio (RTS), quadro de dados e dados e reconhecimento (ACK). Alternativamente, as informações de controle de potência podem ser inseridas em um quadro farol ou quadro de controle individual projetado especificamente para controle de potência. As WTRUs possuem preferencialmente sensores do nível de bateria e ajustam o nível de controle de potência em resposta a nível de bateria verificado. Alternativamente, os APs e WTRUs podem reverter os papéis e as WTRUs podem fornecer informações de nível de potência de transmissão para um AP para facilitar transmissões pelo AP.
