Abstract

resumo estrutura de canal físico de controle de downlink aperfeiçoado (e-pdcch) em evolução de longo prazo (lte) aspectos da presente revelação se referem geralmente aos sistemas de comunicação sem fio e, mais especificamente, à definição de uma estrutura de um canal físico de controle de downlink aperfeiçoado (e-pdcch). certos aspectos proporcionam métodos e aparelhos para determinar um espaço de busca no qual uma estação base (enodeb) pode transmitir um canal físico de controle de downlink aperfeiçoado (e-pdcch), em que o espaço de busca compreende uma ou mais porções fracionárias de recursos de frequência - tempo de um par de blocos de recursos físicos (prb), e tentar decodificar o e-pdcch com base no espaço de busca determinado.
