Patent ID: 8526373

Claim:
A base station apparatus configured to communicate with user equipment terminals using an uplink shared channel, comprising: a first radio resource allocation unit configured to allocate radio resources according to dynamic scheduling among resources other than a resource placed at an end of a system bandwidth, when the system bandwidth is frequency-adjacent to a heterogeneous radio communication system; a second radio resource allocation unit configured to allocate an uplink control channel to the resource placed at the end of the system bandwidth; the radio resource allocation unit further configured to allocate to a user equipment terminal with lower path loss a frequency resource for the shared channel on the side of a heterogeneous radio communication system and allocate to a user equipment terminal with higher path loss a frequency resource for the shared channel on the side of a homogeneous radio communication system, when one end of a system bandwidth is frequency-adjacent to the heterogeneous radio communication system and the other end of the system bandwidth is frequency-adjacent to the homogeneous radio communication system; and a transmission unit configured to transmit radio allocation information to one of the user equipment terminals.
