A pilot structure, a method, and a receiver for multi-carrier cellular communications defining a specific Time Division Multiplexer/Multiplexing pilot pattern and pilot sequence for a sub-frame with short system information. A primary synchronization sequence is configured to be transmitted every predetermine number of sub-frames in a defined bandwidth. A primary common pilot is configured to be transmitted for each sub-frame. Short system information is configured to be transmitted once per frame to define the pilot structure of sub-frames in a frame period to define a structure of a frame period.
