A radio communication apparatus includes a plurality of antennas, a radio transmission unit configured to execute radio transmission processing on data to be transmitted from the plurality of antennas, and a processor connected to the radio transmission unit. The processor executes a process including acquiring beam group specification information that specifies a beam group that is capable of being formed when the data to be transmitted is transmitted, forming at least one beam included in the beam group, and correcting an envelope of a beam group using correction factors, the beam group including the at least one beam formed, the correction factors corresponding to the beam group specification information.

Radio communication apparatus and radio transmission method

A transmission power management device including: a memory, and a processor coupled to the memory and configured to: acquire a first path loss between a first relay station and a second relay station, the first relay station relaying a first signal, the second relay station relaying a second signal, and adjust a first transmission power of the first signal by the first relay station based on the first path loss.

Transmission power management device and transmission power management method

A control apparatus in a wireless communication system including a base station, a plurality of relay stations, and a plurality of terminals, each of the plurality of relay stations being configured to relay wireless signals between the base station and the plurality of terminals, the control apparatus including: a memory, and a processor coupled to the memory and configured to determine relay schedules based on first information associated with first path losses between any pair of the plurality of relay stations, each of the relay schedules defining each of relay periods for each of the plurality of relay stations relaying the wireless signals, and transmit each of the relay schedules to each of the plurality of relay stations respectively.
