System and method of hybrid FDM/TDM coexistence interference avoidance

摘要

A hybrid FDM/TDM solution for in-device coexistence interference avoidance is proposed. A user equipment (UE) comprises a first radio transceiver and a second co-located radio transceiver. The UE detects coexistence interference between the two radios based on radio signal measurement. The UE sends an IDC interference indicator to its serving base station (eNB). The UE also reports IDC information including recommendation for FDM and TDM configurations to the eNB. The eNB receives the IDC interference indicator and evaluates whether to trigger FDM-based solution to mitigate the coexistence interference. The eNB also evaluates whether to trigger TDM-based solution to mitigate coexistence interference. The evaluation is based on the recommended FDM and TDM configurations. The eNB may trigger FDM-based solution, TDM-based solution, or FDM and TDM solution based on the evaluation results of the feasibility and effectiveness of each solution.
