Band selection via coordinated clear channel assessment and switching signaling
A first apparatus may perform a clear channel assessment (CCA) in a first band-operation of a first radio access technology (RAT) in the first band may be synchronized with operation of a second RAT in a second band. The first apparatus may determine whether the CCA indicates that the first band is occupied. The first apparatus may send a first switching signal in the second band based on a determination that the CCA indicates that the first band is occupied. The first apparatus may send data in the second band after the first switching signal is sent. A second apparatus may perform a CCA in a first band-operation of a RAT in the first band may be synchronized with operation of a second RAT in a second band.
