Abstract
The present disclosure outlines mechanisms, systems, methods, techniques and devices that reposition a RMC symbol in a TDD frame. In one aspect, a method queues data transmission units (DTUs) for transmission in a TDD OFDM communication system, with each of the DTUs occupying a single symbol partially or fully, or multiple symbols, of a series of symbols in a TDD frame. The method also forms a management symbol for transmission in a kth symbol position of the series of symbol positions, k>1. The method further transmits the symbols sequentially in the TDD frame.
