Abstract

são providos um aparelho e um método em um sistema de comunicações sem fio. uma estação base é provida com um primeiro número de antenas e um segundo número de ligações em radiofrequência, o segundo número sendo menor do que o primeiro número. um aparelho da estação base compreende: uma unidade de estimativa do ângulo de chegada grosseiro, que estima um par de ângulos de chegada grosseiros por meio de um segundo número de antenas e um segundo número de ligações em radiofrequência; uma unidade de estimativa do ângulo de chegada candidato, que determina um par de ângulos de chegada candidatos com base em um par de ângulos de chegada grosseiros e nas larguras de feixe determinadas por um primeiro número e um segundo número de antenas, respectivamente; e uma unidade de determinação do ângulo de chegada preciso, que calcula a diferença entre o componente de projeção e componente real para os pares de ângulos de chegada candidatos com base em um tom de treinamento proveniente do equipamento de usuário, e designa o par de ângulos de chegada candidatos com a menor diferença entre estes componentes como o par de ângulos de chegada precisos, o componente de projeção sendo determinado pela projeção do sinal realmente recebido pela estação base a partir do tom de treinamento ao longo de um vetor de direção definido por um par de ângulos de chegada candidatos, e o componente real sendo determinado pelo tom de treinamento e pelos parâmetros do estado do canal entre a estação base e o equipamento de usuário.
