    摘要： A method, in a heterogeneous telecommunications network, for mitigating DL-UL interference between an aggressor full-duplex node and a victim full-duplex node, respective nodes operable to serve pairs of half-duplex UEs in full-duplex communication using multiple frequency resources, the method including transmitting an interference indicator message (IIM) from the victim node to the aggressor node including data representing an indication that the victim node intends to schedule full-duplex communication with a pair of half-duplex UEs using a selected one of the multiple frequency resources, wherein the aggressor node, on the basis of the IIM message, is operable to decrease transmission power or cease transmission for a predetermined period of time to a scheduled pair of half-duplex UEs served by the aggressor node in the selected frequency resource, or share scheduling information and data to be scheduled with the victim node whereby to enable interference cancellation for DL-UL interference generated by the full-duplex aggressor node.

    摘要： A method and Base station for Channel State Information estimation in a wireless network is proposed. The wireless network comprises at least one base station. The at least one base station comprises a Large Scalable Antenna System. The Large Scalable Antenna System antenna elements are partitioned in sub-arrays. Precoding vectors for each sub-array are generated such that the antenna beams of the sub-arrays point to different directions. At least one uplink pilot sequence is received by at least one antenna sub-array. A Channel State Information is estimated for the at least one antenna sub-array based on the received pilot sequence. The Channel State Information estimated for at least one antenna sub-array is extrapolated to the antenna elements of the Large Scalable Antenna System.
