Abstract

Various types of communication may switch from an unlicensed spectrum to a licensed spectrum. MiCr communication may be synchronized based on transmission time intervals (TTIs), which may improve the duration required to switch between bands. A MiCr system may transmit a signal to temporarily suspend other traffic in a licensed band so that MiCr communication may occur. For example, an apparatus may be configured to determine synchronization between a first radio access technology (RAT) and a second RAT based on transmission time intervals associated with the first RAT and transmission time intervals associated with the second RAT, switch from the first RAT to the second RAT after the determined synchronization between the first RAT the second RAT; and transmit, during a TTI associated with the second RAT, a first packet using the second RAT based on the switch from the first RAT to the second RAT.
