Dynamic configuration of a flexible orthogonal frequency division multiplexing PHY transport data frame preamble

A transmitter of a base station or a broadcast gateway in a broadcast network, comprising:

• a memory storing program instructions;
• and
• a processor, upon executing the program instructions, configured to:
• generate an initial Orthogonal Frequency Division Multiplexing (OFDM) symbol of a frame control of a broadcast frame in the broadcast network using a first sequence, wherein the initial OFDM symbol is a synchronization symbol configured to enable synchronization and initial channel estimation at a receiver, and wherein the first sequence is generated based on a Zadoff-Chu (ZC) root index value;
• transmit the initial OFDM symbol of the frame control of the broadcast frame to the receiver;
• determine a first cyclic shift based on information to be signaled to the receiver, wherein the information used for determining the first cyclic shift comprises frame configuration information associated with the broadcast frame;
• apply the first cyclic shift to the first sequence to generate a second sequence, wherein the second sequence is based on the ZC root index value;
• generate a second OFDM symbol of the frame control using the second sequence;
• transmit the second OFDM symbol of the frame control of the broadcast frame to the receiver;
• apply a second cyclic shift to the first sequence to generate a third sequence, wherein the third sequence is based on the ZC root index value and wherein the second cyclic shift is based on the frame configuration information associated with the broadcast frame;
• generate a third OFDM symbol of the frame control using the third sequence;
• and transmit the third OFDM symbol of the frame control of the broadcast frame to the receiver.
