Document Type and Number:
Japanese Patent JP6929486
Kind Code:
B2
Abstract:
A mobile station (200) is a wireless communication device that is provided with a plurality of antennas and is capable of transmission processing using delay transmission diversity. The mobile station (200) comprises: a state estimation unit (52) for estimating a mobile state of a wireless communication device on the basis of a transmission path estimation value obtained by a first method and a transmission path estimation value obtained by a second method; and a transmission device (202) for performing, if the mobile state is estimated by the state estimation unit (52) to correspond to a state where a transmission characteristic would deteriorate if delay transmission diversity were performed, processing for stopping use of delay transmission diversity, processing for causing the phase of signals to be transmitted from some antennas of a plurality of antennas to change, or processing for providing a frequency deviation to signals to be transmitted from some antennas.
