Abstract

Se describen técnicas para transmitir datos utilizando una combinación de retardo cíclico explícito y retardo cíclico implícito; un transmisor puede ejecutar un primer procesamiento para diversidad de retardo cíclico (o procesamiento de retardo cíclico explícito) con base en un primer conjunto de valores de retardo cíclico conocidos por un receptor; el transmisor puede ejecutar precodificación con base en una matriz de precodificación ya sea antes o después del procesamiento de retardo cíclico explícito; el transmisor puede ejecutar un segundo procesamiento para diversidad de retardo cíclico (o procesamiento de retardo cíclico explícito) con base en un segundo conjunto de valores de retardo cíclico desconocidos por el receptor; el transmisor puede ejecutar tanto procesamiento de retardo cíclico explicito como implícito para datos y puede ejecutar únicamente procesamiento de retardo cíclico implícito para piloto; una entidad puede seleccionar el primer conjunto de valores de retardo cíclico e informar a la otra entidad; el transmisor puede de manera autónoma (por ejemplo, seudoaleatoria) seleccionar el segundo conjunto de valores de retardo cíclico sin informar al receptor.
