Methods, systems, and devices are described for clear channel assessments (CCAs) on multiple component carriers transmitted using an unlicensed spectrum. A set of component carriers may be identified for transmission of communications signals on the unlicensed spectrum, and a CCA one component carrier of the set may be staggered to occur at a different time than a CCA for a different component carrier of the setoff component carriers. The staggering of CCAs may allow for CCA to be performed at different times for different component carriers, thus increasing opportunities to gain channel access in the unlicensed spectrum. |
