DOWNLINK AND UPLINK INTERFERENCE MITIGATION IN A MULTICELL NETWORK USING INTERFERENCE CANCELLATION AND ORTHOGONAL RESOURCE ALLOCATION

摘要

Interference mitigation in a multicell network uses interference cancellation and orthogonal resource allocation. A backhaul channel is used to share reference signals that may be used to cancel interference from neighboring cell downlink signals. Also, resource blocks assigned to a first user equipment in a first cell are orthogonal to the resource allocated to user equipment assigned to a second user equipment in a second cell that is in close proximity to the first user equipment.
