generate a frame for transmitting data to one or more wireless nodes;
determine whether to include a frame extension after a data symbol in the frame;
determine a length of the frame extension, if the determination is to include the frame extension in the frame, based on an amount of data in the data symbol of the frame and on a ratio of useful coded data bits in the data symbol to total coded bits in the data symbol; and
provide an indication of the length of the frame extension within the frame, if the determination is to include the frame extension;
a first interface configured to output the frame for transmission.
