1. An apparatus, comprising:
at least one processor; and
at least one non-transitory memory comprising computer program code,
the at least one non-transitory memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:
split shared radio-frequency resources into orthogonal resource pool shares;
receive a load metric for respective ones of a plurality of radio access technologies;
assign, based on the load metric, respective ones of the orthogonal resource pool shares to the respective ones of the plurality of radio access technologies;
dynamically adjust a proportion of the assigned orthogonal resource pool shares based on a corresponding load metric of the respective ones of the plurality of radio access technologies at corresponding carriers; and
assign a primary carrier to a user equipment based on the load metric, the orthogonal resource pool share, a coverage of physical channels of the corresponding carriers, and a type of multi-carrier operation for the respective ones of the plurality of radio access technologies.
