Abstract

RELATÓRIO DE FEIXE PARA COMUNICAÇÃO MULTIFLUXO. A presente invenção refere-se a gerenciamento de feixe em comunicação multifluxo entre uma entidade de rede de acesso por rádio e um equipamento de usuário. A entidade de RAN pode transmitir uma pluralidade de feixes de transmissão a partir de uma pluralidade de pontos de transmissão e recepção associados à entidade de RAN para o UE. Para cada um dos feixes de transmissão, o UE pode obter uma métrica de qualidade de feixe em cada um de uma pluralidade de feixes de recepção do UE durante um período de medição para gerar um respectivo vetor de métrica de qualidade de feixe para cada um dos feixes de transmissão. O UE pode, então, transmitir um relatório de feixe incluindo o respectivo vetor de métrica de qualidade de feixe para cada um dos feixes de transmissão para a entidade de RAN. A entidade de RAN pode, então, selecionar pelo menos dois links de pares de feixe, cada um associado a um respectivo TRP, para multiplexação por divisão espacial de pelo menos dois fluxos para o UE com base no relatório de feixe.
