Abstract

recursos de uplink para recuperação de feixe a presente invenção refere-se a métodos, sistemas e dispositivos para comunicação sem fio. recursos de uplink podem ser alocados para transmissões de mensagens de recuperação de feixe. por exemplo, um equipamento de usuário (ue) se comunicando em um sistema que suporta transmissões com filtragem espacial pode receber uma configuração para recursos de uma estação de base, onde os recursos podem ser usados para sinalização de recuperação de feixe. o ue pode identificar uma falha de feixe em um ou mais feixes ativos usados para comunicação com a estação de base, e o ue pode transmitir uma mensagem de recuperação de feixe à estação de base. nesses casos, a mensagem de recuperação de feixe pode ser transmitida de acordo com a configuração recebida da estação de base, de forma que a mensagem de recuperação de feixe seja transmitida usando os recursos de recuperação de feixe. em alguns casos, a configuração pode ser recebida no ue através de sinalização de controle de recursos de rádio (rrc) ou através de um broadcast de informações de sistema da estação de base.
