Abstract

MÉTODO E APARELHO PARA TRANSMITIR UM SINAL DE REFERÊNCIA DE POSICIONAMENTO EM ENLACE DESCENDENTE, E, MEIO DE ARMAZENAMENTO LEGÍVEL POR COMPUTADOR. Um método para transmitir um sinal de referência de posicionamento em enlace descendente é descrito, cujo método pertence ao campo técnico de comunicações sem fio. O método compreende: após receber informações de gatilho de um sinal de referência de posicionamento (PRS) em enlace descendente emitido por um primeiro dispositivo de rede, um terminal recebendo um número especificado de transmissões PRS em enlace descendente em uma localização de recurso sem fio indicada pelas informações de gatilho. Ou seja, na solução mostrada no presente pedido, a localização do recurso sem fio para o número especificado de transmissões PRS em enlace descendente é configurada dinamicamente pelo dispositivo de rede, de modo a realizar o envio sob demanda de PRSs em enlace descendente. Por exemplo, somente quando um terminal precisa medir um PRS em enlace descendente, um dispositivo de rede configura informações de gatilho para o terminal e emite o número especificado de transmissões PRS em enlace descendente, sem a necessidade de envio periódico e contínuo de PRSs em enlace descendente pelo dispositivo de rede, de modo que recursos sem fio sejam bastante economizados.
