Abstract

Описаны системы и способы, способствующие мультиплексированию одноадресных опорных символов и многоадресных передач в одном и том же временном интервале передачи. В частности, обеспечены способы, которые позволяют мультиплексировать одноадресные опорные символы с передачами в одночастотной сети, которые используют длительность более длинного циклического префикса. Одноадресные опорные символы передаются в первом символе слота, который содержит как одноадресную передачу, так и передачу в одночастотной сети. Частота, которая используется для одноадресных опорных символов, чередуется между первым символом и следующим символом в подкадре.
