Abstract

A presente invenção refere-se a técnicas para receber transmissões de canais físicos de controle de downlink com confiabilidade aprimorada em um sistema de comunicação sem fio. Um dispositivo sem fio pode estabelecer um enlace sem fio com uma estação-base celular. O dispositivo sem fio pode receber informações de configuração de canal de controle de downlink da estação-base celular. As informações de configuração de canal de controle de downlink podem configurar recursos de controle associados a múltiplos pontos de transmissão-recepção em um espaço de busca para o dispositivo sem fio. O dispositivo sem fio pode executar a decodificação cega de candidato de canal de controle de downlink durante uma ocasião de monitoramento configurada pelo espaço de busca configurado com recursos de controle associados a múltiplos pontos de transmissão-recepção.
