Abstract

modalidades da presente invenção divulgam um método de identificação de modo de cobertura e um aparelho, usado por uma estação de base para identificar um modo de cobertura de um terminal com base em uma sequência de preâmbulos. o método nas modalidades da presente invenção inclui: determinar, por um terminal, um primeiro modo de cobertura; determinar, pelo terminal, uma sequência de preâmbulos com base no primeiro modo de cobertura; e enviar, pelo terminal, a sequência de preâmbulos a uma estação de base, em que a sequência de preâmbulos é usada para determinar o primeiro modo de cobertura. porque a estação de base pode determinar o modo de cobertura do terminal usando apenas a sequência de preâmbulos enviada pelo terminal, sem usar um canal usado para receber um sinal do terminal, recursos não necessitam ser agrupados ou planejados, e não há necessidade de distinguir estritamente entre conjuntos ou grupos de modo de cobertura diferentes. portanto, recursos de canal podem ser multiplexados, assim melhorando utilização de recurso de canal, e reduzindo complexidade de programação de recurso de canal.
