Abstract
To avoid reference symbol collision, between reference symbols used by neighboring cells in an OFDM based cellular telecommunications network, the transmission symbols on a given subcarrier used by respective neighboring base stations are compared and where both transmission symbols are determined to be reference symbols the start time of the frame timing period of one of the base stations is adjusted.
