Abstract

as transmissões que comunicam o intervalo de escalonamento do duplex de divisão de tempo (tdd) em uma primeira direção podem incluir uma ou mais regiões para se comunicarem em uma segunda direção, em que a primeira direção é uma direção de transmissão e a segunda direção é uma direção de recepção ou vice-versa. um quadro de rádio pode incluir intervalos de escalonamento tdd com tais regiões e/ou intervalos de escalonamento tdd sem essas regiões para comunicação sem fio, e esses intervalos de escalonamento tdd podem ainda ser configurados de acordo com diferentes configurações de estrutura de quadro, tais como diferentes comprimentos de intervalo de escalonamento, espaçamentos de subportadora ou durações de símbolos.
