基地局装置及び通信制御方法
Document Type and Number:
Japanese Patent JP5119235
Kind Code:
B2
Abstract:
A base station apparatus is disclosed that includes a selection unit selecting user equipment terminals to which radio resources are allocated based on priority levels indicating a priority order of allocating the radio resources for a shared channel and a resource determination unit determining a transmission power level of a control channel and resources for the control channel, the control channel indicating communications of the shared channel to the selected user equipment terminals. In the base station apparatus, when the sum of the transmission power of the control channel related to the selected user equipment terminals exceeds a predetermined first threshold value or when a sum of control resources for the control channel related to the selected user equipment terminals exceeds a predetermined second threshold value, the resource determination unit transmits the control channel to some user equipment terminals among the selected user equipment terminals.
