Abstract
An unmanned aerial vehicle (UAV) user equipment (UE) device determines uplink transmission power based on a reduced power factor in response to receiving an interference indicator from a neighboring base station. The reduced power factor results in an uplink transmission power for an uplink signal that is less than the uplink transmission power based on a standard power factor.
Claims22
A method comprising:
- monitoring, at an unmanned aerial vehicle (UAV) user equipment (UE) device, a downlink wireless channel for an interference indicator transmitted from a non-serving base station;
- if the interference indicator has been received, determining an uplink transmission power for transmitting uplink signals to a serving base station based on a reduced power factor resulting in a reduced uplink transmission power level;
- and
- if the interference indicator has not been received, determining the uplink transmission power level based on a standard power factor resulting in a standard uplink transmission power level greater than the reduced uplink transmission power level.
1 more element
An unmanned aerial vehicle (UAV) user equipment (UE) device comprising:
- a receiver configured to monitor a downlink wireless channel for an interference indicator transmitted from a non-serving base station;
- a controller configured to:
- if the interference indicator has been received, determine an uplink transmission power for transmitting uplink signals to a serving base station based on a reduced power factor resulting in a reduced uplink transmission power level;
- and
- if the interference indicator has not been received, determine the uplink transmission power level based on a standard power factor resulting in a standard uplink transmission power level greater than the reduced uplink transmission power level.
2 more elements
A method comprising:
- receiving, from an unmanned aerial vehicle (UAV) user equipment (UE) device at a serving base station, a power reduction request message indicating that the UAV UE device has received an interference indicator from a non-serving base station;
- transmitting a power factor message to the UAV UE device, the power factor message instructing the UAV UE device to use a reduced power factor to determine a reduced uplink transmission power level for transmitting uplink signals to the serving base station, the reduced uplink transmission power level being less than a standard uplink transmission power level based on a standard power factor.
