Scheduling map(s) are generated and updated for employment in an access division multiplexing (ADM) environment for allocating resource utilization (e.g., use of transmission time intervals) to or between differing radio access technology networks, and particularly to a Long Term Evolution (LTE) network and a Global System for Mobile communication (GSM) network. In some example embodiments the scheduling map(s), apparatus, and methods hereof are implemented in a wireless terminal which participates in access division multiplexing between the differing radio access technologies, in other example embodiments the scheduling map(s), apparatus, and methods hereof are implemented in a network node (e.g., eNodeB) of one of the radio access technology networks, e.g., the Long Term Evolution (LTE) network.
