Abstract
A control unit allocates sequentially a channel for use in data transmission and a channel for use in channel estimation used to acquire channel characteristics between a radio apparatus and another radio apparatus to be communicated with, to the another radio apparatus. A radio unit to an IF unit communicate with the another radio unit through the sequentially allocated data transmission channels, respectively. An acquisition unit acquires the traveling speed of the another radio apparatus in communication with the radio apparatus. A decision unit varies the frequency at which the channel for use in channel estimation is allocated, based on the traveling speed acquired.
