Radio Unit and a Method Therein for Controlling Power Levels of Spatially Separated Transceivers in a Wireless Communications Network

A radio unit for controlling power levels of spatially separated transceivers connected to the radio unit via corresponding antenna ports, wherein each transceiver is capable of performing measurements on uplink transmissions from wireless devices in a wireless communication network, the radio unit comprising

• a receiver configured to receive signal quality measurements from the transceivers on received uplink transmissions from the wireless devices, wherein each signal quality measurement is indicative of a received signal quality of an uplink signal from one of the wireless devices to one of the transceivers;
• and
• processing circuitry configured to:
• compute a load for each transceiver based on the received signal quality measurements, wherein the load for each transceiver is computed as a number of wireless devices for which the received signal quality measured by the transceiver ranks as dominant compared to the received signal qualities measured by other transceivers;
• and
• control a power level of a first transceiver based on the determined load for the first transceiver and the computed load of at least one other transceiver.

A non-transitory computer readable recording medium storing a computer program product for controlling power levels of spatially separated transceivers connected to a radio unit via corresponding antenna ports, wherein each transceiver is capable of performing measurements on uplink transmissions from wireless devices in a wireless communication network, the computer program product comprising software instructions which, when run on processing circuitry of the radio unit, causes the radio unit to:

• receive signal quality measurements from the transceivers on received uplink transmissions from the wireless devices, wherein each signal quality measurement is indicative of a received signal quality of an uplink signal from one of the wireless devices to one of the transceivers;
• compute a load for each transceiver based on the received signal quality measurements, wherein the load for each transceiver is computed as a number of wireless devices for which the received signal quality measured by the transceiver ranks as dominant compared to the received signal qualities measured by other transceivers;
• and
• control a power level of a first transceiver based on the determined load for the first transceiver and the computed load of at least one other transceiver.
