Title: TECHNIQUES FOR ENABLING ASYNCHRONOUS TRANSMISSIONS IN AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND
Abstract:
Techniques are described for wireless communication. One method includes monitoring, by a first base station of a first operator, for clear channel assessment (CCA) exempt transmission (CET) timing information of a second base station of a second operator; identifying transmission timings of CETs of the second base station of the second operator based at least in part on the monitoring; and discontinuing transmissions of the first base station of the first operator during the transmission timings of the CETs of the second base station of the second operator. Transmissions of the second base station of the second operator may be asynchronous to transmissions of the first base station of the first operator.
