Radio base station and power control method

摘要

Disclosed is a wireless base station (eNB10-1) which calculates resource block usage based on the number of resource blocks in the downstream direction (downstream resource block usage) and the number of resource blocks in the upstream direction (upstream resource block usage) allocated to a wireless terminal (UE30-1), and sets the number of DSP for which a power supply should be turned on in a manner such that the number of DSP for which a power supply should be turned on is reduced as resource block usage decreases. In addition, the wireless base station (eNB10-1) turns on the power supply for the set number of DSP and turns off the power supply for the remaining DSP.

1. A radio base station connected with a radio terminal, comprising:
a plurality of communication processing units that are turned on or off independently; and a control unit that controls power of the plurality of communication processing units, wherein the control unit performs a control for turning on the communication processing units of which the number of communication processing units corresponds to a usage amount with a larger value between a usage amount of an uplink radio resource and a usage amount of a downlink radio resource used by the connected radio terminal.
