Abstract

a presente invenção é projetada de modo a permitir o gerenciamento de feixe adequado (incluindo, por exemplo, relato e/ou indicação de feixes). de acordo com a presente invenção, um terminal de usuário tem uma seção receptora que recebe um canal de controle de enlace descendente (dl) para um primeiro espaço de busca e uma seção de controle que especifica um feixe que é utilizado para transmitir e/ou receber um canal de controle dl para o primeiro espaço de busca com base em associações entre portas de antenas de sinais de referência de demodulação e sinais de medida de mobilidade.
