Abstract

Для поддержания поиска сот, несколько (например, две) передачи синхронизации отправляются в кадре с неравномерным разнесением. Информация передается через неравные расстояния между последовательными передачами синхронизации. Несколько уровней неравномерного разнесения могут использоваться для того, чтобы передавать разные типы информации. В одной схеме несколько передач синхронизации отправляются в разных субкадрах кадра, и каждая передача синхронизации отправляется в одном из нескольких периодов символа в соответствующем субкадре. Передачи синхронизации могут быть отправлены в неравномерно разнесенных субкадрах, чтобы передать границу кадра. Одна передача синхронизации может быть отправлена в одном из нескольких возможных периодов символа в зависимости от информации, которая передается, например, конкретной группы идентификаторов сот. Расстояния между передачами синхронизации также могут использоваться для того, чтобы передавать длину циклического префикса. Передача дополнительной синхронизации, которая переносит идентификатор сот, может быть отправлена с предварительно определенным смещением от одной из нескольких передач синхронизации.
