Patent ID: 7551546

Claim:
A wireless terminal for communicating over a shared OFDM band, the wireless terminal comprising: a first transmit chain configured to generate and transmit a low rate mode OFDM transmission in a first frequency band of the shared OFDM band in a first subset of a plurality of OFDM transmission intervals; and a second transmit chain configured to generate and transmit a burst-mode transmission in a second frequency band of the shared OFDM band in a second subset of the plurality of OFDM transmission intervals, the first subset of the plurality of OFDM transmission intervals having at least one OFDM transmission interval in common with the second subset of the plurality of OFDM transmission intervals, wherein for the at least one OFDM transmission interval common between the first subset and the second subset, the first frequency band is non-overlapping in frequency with the second frequency band.
