Abstract
Methods and systems for multi-protocol transmissions in shared spectrum are disclosed. According to principles described herein, a wireless transmitter is configured to generate subcarriers or symbol information from one OFDM technology using subcarriers of another OFDM technology. With this approach, a wireless transmitter configured to transmit OFDM symbols using subcarriers and a subcarrier frequency spacing associated with one OFDM protocol can also be configured to transmit OFDM symbols associated with another OFDM protocol which normally uses different subcarriers and a different subcarrier frequency spacing. In one application, an LTE transmitter uses LTE subcarriers to generate 802.11 (e.g. Wi-Fi) subcarrier or symbol information that can be understood by Wi-Fi receivers, for example to reserve the channel for a certain duration, to indicate a transmission time associated with an on-going and/or upcoming symbol transmission or to create a carrier sense indication, for example, to cause Wi-Fi receivers and other radio technologies to consider the channel as busy.
