Abstract

a presente invenção refere-se a um método e dispositivo para transmitir informações de controle de downlink. o método compreende: uma estação-base determina um período de detecção de um aparelho de terminal que detecta dci, e pelo menos um tempo de detecção dentro do período de detecção, em que o período de detecção compreende pelo menos dois ttis, que compreendem pelo menos um tti que carrega a dci e pelo menos um tti que não carrega a dci, o pelo menos um tempo de detecção tem uma correspondência de um para um com o pelo menos um tti que carrega a dci, e o pelo menos um tempo de detecção coincide com o tempo de início do pelo menos um tti que carrega a dci; e uma estação-base envia, no pelo menos um tempo de detecção dentro do período de detecção, a dci para o aparelho de terminal. neste modo, a presente invenção efetivamente reduz o número de operações de detecção às cegas de pdcch executadas pelo ue sem influenciar um serviço a ser transmitido, assim reduzindo o consumo de energia e excessos de processamento do ue.
