Abstract: Inter-radio access technology (inter-RAT) load balancing under multi-carrier dynamic spectrum sharing (SS) context is provided. One method may include splitting shared radio-frequency resources into orthogonal resource pool shares. The method may include receiving a load metric for each of a plurality of radio access technologies. The method may include assigning, based on the load metric, one of the resource pool shares to each of the plurality of radio access technologies. In addition, the method may include dynamically adjusting a proportion of the assigned resource pool shares based on the load metric of each of the plurality of radio access technologies at corresponding carriers. The method may include assigning a primary carrier to a user equipment based on the load metric, the resource pool share, a coverage of the carriers' physical channels, and a type of multi-carrier operation for each of the plurality of radio access technologies.
