POWER SUPPLY UNITS AND BASEBAND PROCESSING UNITS FOR RADIO ACCESS NETWORK NODES

摘要

According to an aspect, there is provided a power supply unit, PSU, configured for use in a first radio access network, RAN, node in a communication network. The PSU comprises a power supply input interface configured to enable the PSU to be connected to, and receive electrical power from, an electrical power supply; and a power line communication, PLC, unit connected to the power supply input interface and configured to connect to a first baseband, BB, processing unit in the first RAN node. The first BB processing unit is configured for processing baseband signals in the first RAN node. The PLC unit is configured to operate according to a PLC protocol to enable communications between the first BB processing unit and a second BB processing unit in a second RAN node that is also connected to the electrical power supply.
