Abstract
Small-cell LTE and Wi-Fi networks are both currently deployed in the unlicensed 5 GHz bands globally, leading to the need for new coexistence regulations between two very different access technologies. 3GPP standardized LTE Licensed Assisted Access (LTE-LAA) addresses the above coexistence challenge with Wi-Fi through incorporation of similar sensing and back-off features. The success of LAA's fair and efficient coexistence with Wi-Fi can be considered a benchmark for collaborative cellular operation in unlicensed bands.
