Abstract

MÉTODOS PARA MEDIÇÕES DE AUTOINTERFERÊNCIA E INTERFERÊNCIA DE ENLACE CRUZADO EM BANDAS DE ONDA MILIMÉTRICA. Trata-se de métodos, sistemas e dispositivos para comunicações sem fio para medições de autointerferência ou interferência de enlace cruzado em um equipamento de usuário (UE). Um UE pode receber informações de configuração de uma estação-base que indica um ou mais valores de índice de formato de slot (SFI) que são compatíveis com medições de autointerferência e interferência de enlace cruzado. Com base no SFI (ou SFIs) configurado, o UE pode medir a interferência em múltiplos símbolos, que podem ser usados para estimar uma quantidade de interferência de enlace cruzado ou autointerferência, e o UE pode transmitir um relatório de medição para a estação-base. A estação-base, com base no relatório de medição, pode identificar um ou mais SFIs compatíveis, pares de feixes ou combinações dos mesmos para comunicações subsequentes com um ou mais UEs. As medições de interferência podem identificar a interferência de enlace cruzado no UE que resulta de transmissões de um UE diferente, ou podem identificar a autointerferência de comunicações simultâneas de múltiplos canais em um mesmo UE.
