Method and system for determining an interference contribution from a time division duplexing system
Patent number: 11463884Abstract: Techniques are provided for more accurately determining interference contribution at a point in a neighborhood of a time division duplexing (TDD) system operating in shared frequency spectrum. If at least one TDD radio, of a TDD system, is in the neighborhood, then determine a largest interference level, at the point in the shared frequency spectrum, by a TDD radio of the TDD system, where the TDD radio is in the region around the point. The largest interference level is selected as the aggregate interference contribution of the TDD system for interference analysis in the shared spectrum at the point.Type: GrantFiled: July 10, 2019Date of Patent: October 4, 2022Assignee: CommScope Technologies LLCInventors: Ariful Hannan, Raina Rahman, Navin Srinivasan -
