Abstract

a presente invenção fornece um método para transmitir um sinal de controle de enlace descendente e um aparelho. o método inclui: enviar, por meio de uma estação-base, um ou mais quadros de rádio, em que o um ou mais quadros de rádio incluem uma pluralidade de símbolos de multiplexação por divisão de frequência ortogonal (ofdm) que portam sinais de sincronização, cada símbolo de ofdm que porta um sinal de sincronização é enviado por meio do uso de um ou mais feixes de enlace descendente da estação-base, e os símbolos de ofdm que portam o sinal de sincronização ainda portam um sinal de controle de enlace descendente. o sinal de controle de enlace descendente é colocado em um símbolo de ofdm que porta o sinal de sincronização, e, assim, as despesas gerais de sinalização são reduzidas.
