Abstract

Un bloque de recursos puede incluir todos los símbolos en una ranura para cada, generalmente un múltiplo de 12, subportadora en el bloque de recursos; una ranura por lo regular es de 0.5 milisegundos (ms) e incluye 7 símbolos para prefijo cíclico corto (CP) y 6 símbolos para CP largo; el bloque de recursos puede incluir un canal SRS así como otros canales tales como el canal de reconocimiento (ACK) y un canal de indicación de calidad de canal (CQI); aunque se define como un canal físico separado, el SRS se puede multiplexar con canales de enlace ascendente; de acuerdo con esto, un SRS puede ser detectado en una ranura de un subcuadro de 1.0 ms que constituye dos ranuras, por lo regular, una ranura pero no la otra incluye el SRS; la estructura de la ranura se puede modificar para facilitar la multiplexión, por ejemplo, reemplazando un símbolo existente con el SRS, y una longitud y un tipo de un código de esparcimiento ortogonal de dominio de tiempo se puede determinar para cada ranura como una función de la presencia de SRS.
