Abstract

resumo patente de invenção: "controle de energia de sinais de descoberta de vizinho". a presente invenção refere-se a um método de ajustar energia de um sinal de descoberta de vizinho, que pode incluir determinar uma energia máxima de transmissão de um dispositivo sem fio que transmite. o dispositivo sem fio que transmite pode ser configurado para transmitir um sinal de descoberta de vizinho para um ou mais dispositivos sem fio que recebem. o um ou mais dispositivos sem fio que recebem podem ser dispositivos sem fio vizinhos descobertos do dispositivo sem fio que transmite, e podem ser configurados para receber o sinal de descoberta de vizinho. o método pode ainda incluir determinar o nível de energia do sinal de descoberta de vizinho com base na energia máxima de transmissão do dispositivo sem fio que transmite e um número dos dispositivos sem fio vizinhos descobertos.
