Standardized inter-base station reporting of pilot contamination for improved pilot resource re-use

摘要

The invention is directed to systems, methods and computer program products for standardized inter-base station reporting of pilot contamination for improved pilot resource re-use. Specifically, possible pilot channel contamination is detected at first user equipment and, in response to the detection, a request is transmitted for the first user equipment to forego transmission during a next frame designated for transmitting a pilot signal. A determination is made within the next frame if other second user equipment, which are communicating with a neighboring base station, are transmitting on a same channel as a pilot channel of the first user equipment and, in response to such a determination, a report is sent to the neighboring base stations that indicates that the pilot channel on which the first user equipment is communicating is currently contaminated.
