Dynamic interference avoidance in integrated multi-radio access technolgies (rat) heterogeneous networks

An evolved nodeB (eNodeB), comprising:

• a radio resource controller (RRC) arranged to manage radio resources and to generate control signals, the RRC further arranged to handle signals for a multi-mode user equipment including signals for transmission via a WiFi link arranged to transmit data for a cellular session and a 4G link arranged to transmit data for the cellular session;
• and
• a Multi-radio access technologies (RAT) aggregation function arranged to provide a high data transfer rate through multiple carrier components including a primary cell to provide 4G services and a secondary cell to provide wireless local area network (WLAN) service;
• wherein the RRC includes a multi-RAT coordination function (MRCF) arranged to periodically determine when to re-partition RAT assignments to dynamically adapt RAT assignments assigned across WiFi to provide WLAN service and Long Term Evolution (LTE) interfaces to provide fourth generation (4G) services to dynamically mitigate changing interference.

A method, comprising:

• performing initial radio access technology (RAT) assignments for a multi-mode user equipment;
• setting an update period counter to equal an update period;
• obtaining quality measurements associated with a plurality of RATs during the update period;
• implementing communication by the multi-mode user equipment with assigned RATs based on the obtained quality measurements and collecting quality measurements associated with the plurality of RATs during a current frame until the update period has expired;
• repartitioning the multi-mode user equipment to different RATs from among the plurality of RATs based on the collected quality measurements associated with the plurality of RATs;
• and
• resetting the update period counter to equal the update period when the update period has expired.
