High frequency radio environmental mapping and system procedures
Systems, methods, and instrumentalities are provided to implement a method for radio environment, measurement (REM) scheduling, information extraction, storage and processing to generate terrain and object mapping/identification using higher frequency radio signals, directional transmission techniques and external database information.
