Abstract

[objetivo] prover um dispositivo de terminal capaz de realizar eficientemente a comunicação em um sistema de comunicação no qual um dispositivo de estação base e o dispositivo de terminal comunicam um com o outro. [solução] esse dispositivo de terminal que comunica com um dispositivo de estação base que inclui: uma unidade de recepção configurada para monitorar um primeiro pdcch que é transmitido com base em um subquadro que é definido por um número de símbolos pré-determinado, e um segundo pdcch que é transmitido com base em um subquadro estendido que tem um número de símbolos menor do que um número de símbolos correspondentes ao subquadro e um bloco de recurso que é definido de acordo com uma segunda definição de pdcch. um primeiro pdsch alocado pelo primeiro pdcch é mapeado com base em um par de blocos de recurso correspondente ao número de símbolos do subquadro. um segundo pdsch alocado pelo segundo pdcch é mapeado com base em um sub-bloco de recurso correspondente ao número de símbolos do subquadro estendido.
