1. A method, comprising:
- at a base station;
determining a network topology in an area of the base station, wherein the determining includes scanning channels in an unlicensed frequency band based on a power spectral density estimation;
communicating with a user equipment (UE) on a primary component carrier served by the base station; and
performing a secondary cell add procedure to select a secondary component carrier on which a further base station can communicate with the UE, wherein the selection of the secondary component carrier is based at least in part on the network topology and wherein the secondary component carrier is served in the unlicensed frequency band.

Abstract
Described herein are systems and methods for carrier aggregation deployment and organization in unlicensed bands. A method may comprise scanning, by a transceiver within a base station, channels in a band of interest, reporting, by the transceiver, signal measurement information to the base station, cell searching, by the transceiver, channels in the band of interest, determining channel information for neighboring each channel, and transmitting, by the transceiver, the channel information to the base station.
