Abstract:
Methods and a system are provided for enabling coexistence of WIFI and Long Term Evolution (LTE) in a wireless communication system. A method includes embedding in a data sequence, by a base station capable of transmitting and receiving LTE frames, a channel reservation packet that (i) is detectable by a WIFI receiver and (ii) reserves a particular one of a plurality of available unlicensed communication channels for a transmission duration of the data sequence. The method further includes transmitting, by the base station, the data sequence including the embedded channel reservation packet.
