| 20100046680 | Communication Device and Control Method - A communication device according to the present invention includes a receiver configured to receive, through a radio link, packet signals each including a known signal indicating information known by the communication device and an unknown signal indicating information not known by the communication device, and a combiner configured to combine the packet signals while decreasing noise signals included in each of the packet signals. The communication device includes a correlation comparator configured to compare a correlation between the known signals in each of the packet signals with a correlation between the unknown signals in each of the packet signals, and a combining scheme controller configured to control a scheme of combining the packet signals, on the basis of the comparison result by the correlation comparator. | 02-25-2010 |
| 20100142441 | RADIO COMMUNICATION METHOD AND BASE STATION - Provided is a radio communication method employed in a base station having plural antenna elements. The method includes the steps of: setting an inner zone and an outer zone by dividing a cell formed by the base station into two; determining whether a mobile station is located in the inner zone or the outer zone on the basis of a predetermined criterion; notifying the mobile station located in the inner zone of control information, including information on channel allocation and a communication method, through a broadcast channel; and notifying the mobile station located in the outer zone of control information through a dedicated channel by beamforming using the plural antenna elements. | 06-10-2010 |
| 20100150083 | Radio Base Station and Channel Allocation Information Transmission Method - A radio base station includes: a propagation path characteristic acquisition unit which acquires propagation path characteristics between a radio communication terminal and a radio base station; and a channel controller which reports to the radio communication terminal that channel allocation information is transmitted by using a dedicated control channel if the acquired propagation characteristic satisfies a predetermined condition. After the channel control unit has reported to the radio communication terminal that the channel allocation information is transmitted by using an dedicated control channel, the channel control unit and a MAP processing unit transmit the channel allocation information by using an dedicated control channel instead of a broadcast control channel in the downstream frame. | 06-17-2010 |

| 20100159844 | Radio Communication Device and Radio Communication Method - A radio communication device according to the present invention is a radio communication device which adaptively controls directivity of transmission radio signals by use of a plurality of element antennas on the basis of received radio signals received from a counterpart radio communication device that is a communication target radio communication device, the transmission radio signals being to be transmitted to the counterpart radio communication device, the radio communication device comprising: a propagation path state detector configured to detect a fluctuation state of a propagation path to the counterpart radio communication device on the basis of the received radio signal; and a transmission controller configured to control a phase of the transmission radio signal on the basis of the fluctuation state of the propagation path detected by the propagation path state detector. | 06-24-2010 |
| 20100173592 | Radio Communication Device and Radio Communication Method - A radio communication device according to the present invention adaptively controls directivity of a transmission radio signal by using a plurality of element antennas on the basis of a received radio signal received from a communication target counterpart radio communication device. The radio communication device includes a transmission controller configured to process the transmission radio signal according to a first control method for adaptively controlling the directivity, a propagation path state detector configured to detect fluctuation state of a propagation path to a counterpart radio communication device, and a judgment unit configured to judge whether or not to change the directivity on the basis of the fluctuation state of the propagation path. If it is judged that the directivity is to be changed, the transmission controller switches to a second control method that is different from the first control method, and processes the transmission radio signal according to the second control method. | 07-08-2010 |
