Abstract
The present invention relates to a device and method for adaptively controlling power consumption in a communication node. The communication node includes a plurality of hardware units, including a modem and at least two transceiver branches, wherein each hardware unit may be powered on/off during operation of the communication node. The communication node is configured to determine current traffic requirements and to estimate future traffic requirements and then adapt the power consumption level by powering on/off the hardware units with regard to current traffic requirements and estimated future traffic requirements.
Claims20
A communication node for adaptively controlling power consumption, the communication node comprising:
- a plurality of hardware units, including a modem unit and at least two transceiver front-end units wherein, each of the hardware units being associated with a power consumption level, a data throughput and a wake-up time;
- a processing unit configured to determine current traffic requirements and to estimate future traffic requirements based on at least one of current traffic requirements, historical data, weather information and network information;
- and
- a power control unit configured to adapt the power consumption level of the communication node by powering on/off the hardware units with regard to current traffic requirements and estimated future traffic requirements.
A method in a communication node for adaptively controlling power consumption, the communication node comprising a plurality of hardware units, including a modem unit and at least two transceiver front-end units, each of the hardware units being associated with a power consumption level, a data throughput and a wake-up time, the method comprising the steps of:
- determining current traffic requirements;
- estimating future traffic requirements based on at least one of current traffic requirements, historical data, weather information and network information;
- and
- adapting the power consumption level of the communication node by powering on/off the hardware units with regard to current traffic requirements and estimated future traffic requirements.
