Abstract

INDICAÇÕES DE FEIXE PARA FACILITAR ACESSO DE MULTICAST POR EQUIPAMENTO DO USUÁRIO COM CAPACIDADE REDUZIDA. Aspectos da revelação referem-se a transmitir, a partir de um equipamento do usuário (UE) para uma estação base, informação indicativa de uma sessão de multicast que o UE está interessado em acessar; transmitir informação indicando que um primeiro feixe de vários de feixes é um feixe preferido para receber dados de multicast associados à sessão multicast; receber, a partir da estação base, uma lista de pelo menos um feixe dos vários feixes associados à sessão multicast; e receber, a partir da estação base usando um feixe a partir da lista, dados multicast associados à sessão multicast. Outros aspectos, concretizações e características também são reivindicados e descritos.
