Abstract: Systems and methods providing uplink coordinated multi-point (CoMP) communication are shown. A second cell may identify at least one first UE communicating with a first cell and capable of causing high uplink interference to the second cell. The second cell may estimate uplink interference from the at least one first UE at the second cell. The second cell may estimate uplink interference on specific resources. For example, the second cell may determine resources assigned to the at least one first UE for data transmission to the first cell (e.g., using pre-scheduling information provided by the first cell) and estimate uplink interference from the at least one first UE on the resources assigned to the at least one first UE. The second cell may schedule at least one second UE for uplink data transmission to the second cell based on the estimated uplink interference from the at least one first UE.
