...This is quite different from current approaches, for example, in the coexistence scenario between LTE in unlicensed bands and WiFi, where the utilization of bandwidth reduction [27], duty-cycling muting, or blank subframes [26] is unilaterally taken by LTE, while the implementation of listen-before talk before transmitting LTE frames requires to build new LTE radio [27, 28]....
