Abstract
In some aspects, the disclosure is directed to methods and systems for intelligent transmit power management. Output power levels may be dynamically determined responsive to REM measurements, user equipment (UE) signal reports, information received from other cells (e.g. via X2 application protocol (X2AP) or other such communication protocols), or any combination of these or other information in an iterative level conditioning and limit checking process.
Claims12
A method for transmit power management, comprising:
- receiving, by a first device transmitting on a first channel from each of a first one or more other devices, a reference signal received power (RSRP) measurement and a cell type identifier;
- determining a first output power level, by the first device, based on the received RSRP measurements corresponding to each value of the cell type identifier;
- receiving, by the first device from each of a second one or more other devices transmitting on channels adjacent to the first channel, a RSRP measurement;
- determining a second output power level, by the first device, based on a maximum received RSRP measurement of devices transmitting on adjacent channels;
- and
- selecting, by the first device, a maximum transmission output power from a minimum of the first and second determined output power levels.

A device for transmission power management, comprising:
- a transmitter transmitting on a first channel
- a receiver configured to:
- receive, from each of a first one or more other devices, a reference signal received power (RSRP) measurement and a cell type identifier, and
- receive, from each of a second one or more other devices transmitting on channels adjacent to the first channel, a RSRP measurement;
- and
- a processor configured to:
- determine a first output power level, based on the received RSRP measurements corresponding to each value of the cell type identifier,
- determine a second output power level, based on a maximum received RSRP measurement of devices transmitting on adjacent channels, and
- select a maximum transmission output power from a minimum of the first and second determined output power levels.
