A method for wireless backhaul communication, a radio access unit and a central unit therefor

摘要

The invention concerns a method for wireless communication in a communication network comprising a central unit (CU) and a radio access unit (RAU), wherein backhaul signals are transmitted between the central unit (CU) and the radio access unit (RAU) via a wireless backhaul link, a part of received backhaul signals in downlink is coupled out and amplified in the radio access unit (RAU) and sent back to the central unit (CU) via the wireless backhaul link, said part of the received backhaul signals in downlink which is amplified and sent back to the central unit (CU) is measured in the central unit (CU), and the central unit (CU) adapts downlink transmission via the wireless backhaul link based on measurement results of said part of the received backhaul signals in downlink which is amplified and sent back to the central unit (CU), a radio access unit and a central unit therefor.
