Abstract
Methods and systems for Long Term Evolution (LTE) and Fifth Generation (5G) beam index filtering are presented. According to one aspect, a method for beam index filtering comprises receiving a beam index that was estimated based on information received from a User Equipment (UE); storing the received beam index into a queue of length N for storing received beam indexes, N being greater than one; selecting a beam index from the queue according to a filtering algorithm; and using the selected beam index for transmissions to the UE. In one embodiment, a majority vote algorithm is employed to select the beam index that appears most often in the queue. Where there is a tie between two or more beam indexes, the beam index that was most recently added to the queue is selected. The same concepts may be applied to filter input data or parameters other than beam indexes.
