Abstract
Methods and apparatuses are disclosed for providing flexible channel information feedback. In some cases this may be according to reporting types assigned by one or more sectors, with different reporting types for each sector. In other cases, a reporting mode is determined to determine the reporting types to be utilized.
Claims35
