Abstract

em um aspecto, um método de comunicação sem fio por um dispositivo sem fio inclui gerar, pelo dispositivo sem fio, um cabeçalho de unidade de dados de protocolo (pdu) e uma carga útil de pdu correspondente de um pacote de ângulo de chegada (aoa). a geração da carga útil de pdu inclui inserir um campo suplementar e um campo de verificação de redundância cíclica (crc) na carga útil de pdu. o campo suplementar é configurado para habilitar outro dispositivo sem fio para determinar um ângulo de chegada do pacote de aoa e o campo de crc corresponde a uma crc pelo menos do campo suplementar. o método também inclui transmitir o pacote de aoa com uma antena única do dispositivo sem fio.
