1. A method for wireless communication, comprising:

  • 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 at least one second operator, wherein the first base station is deployed in a first network of the first operator and the second base station is deployed in a second network of the second operator, and transmissions of the second base station of the at least one second operator are asynchronous to transmissions of the first base station of the first operator;

    identifying transmission timings of CETs of the second base station of the at least one second operator based at least in part on the monitoring, wherein the CETs are transmitted to a first mobile device served by the second base station and deployed in the second network of the second operator; and

    discontinuing the transmissions of the first base station of the first operator during the transmission timings of the CETs of the second base station of the at least one second operator.
