Aspects of a method and system for an RS frequency control loop for TXCO synchronization and tracking may include tracking a carrier frequency in an Orthogonal Frequency Division Multiplexing (OFDM) signal based on at least a reference symbol set. A receiver frequency may be adjusted based on at least the tracked carrier frequency. The carrier frequency may be tracked by generating an output signal as a function of a frequency offset Deltaf in a frequency discrimination feedback loop. The reference symbol (RS) set may be generated in an RS extraction module or circuit, from at least a fast Fourier transform of the received OFDM signal. The receiver frequency may be coarsely adjusted and then finely adjusted. The coarse receiver frequency adjustment may be based on processing at least a primary synchronization signal and a secondary synchronization signal.
