| 20110026491 | ALLOCATION METHOD AND BASE STATION APPARATUS USING THE SAME - A base station apparatus and an allocation method are provided. The base station apparatus includes an allocation unit and a communication unit. The allocation unit allocates, in a frame, different channels for data between a base station apparatus and a terminal device and control information about the data, the frame formed with a plurality of time slots being time-multiplexed, each time slot formed with a plurality of channels being frequency-multiplexed. The communication unit performs communication with the terminal device by using the control information and the data, to which a channel is allocated. The allocation unit, while securing at least the control information, releases at least one data which is not secured, and instructs the terminal device to perform handover process by using a time slot, in which no data is allocated. | 02-03-2011 |
| 20110134789 | REPORT METHOD AND ACCESS CONTROL DEVICE - It is specified that a frame containing at least the plurality of slots is repeated. A detecting unit detects a slot usable in the communications between terminal apparatuses, from among a plurality of slots. A modem unit and an RF unit broadcast the information on the detected slot. A power measuring unit in the detecting unit measures the respective received powers of the plurality of slots, and an empty slot identifying unit identifies a slot whose received power is less than a threshold value. | 06-09-2011 |
| 20110170484 | RADIO APPARATUS WHICH COMMUNICATES WITH OTHER RADIO APPARATUSES AND COMMUNICATION SYSTEM - A data processing unit selects either one of a base station mode and a terminal mode so as to perform communications using packet signals. The base station mode is a mode in which a packet signal, containing data indicating that an initial source and a final destination are not its own radio apparatus, is to be communicated; the terminal mode is a mode in which a packet signal, containing data indicating that the initial source or the final destination is its own radio apparatus, is to be communicated. A control unit starts the radio apparatus by setting the data processing unit in the terminal mode. When a packet signal, which has been transmitted from another radio apparatus and which contains broadcast information, has not been received before a certain period of time elapses after the start, the control unit switches the mode of the data processing unit to the base station mode. | 07-14-2011 |
| 20110205971 | WIRELESS DEVICE - A data processing section ( | 08-25-2011 |
| 20110211455 | REPORT METHOD AND ACCESS CONTROL DEVICE AND RADIO DEVICE USING THE METHOD - A frame specifying unit frames in such a manner that a frame containing at least a plurality of slots is repeated and in such a manner that a part of the plurality of slots contained in each frame are reserved for use on an access control apparatus. An empty slot identifying unit detects a slot, which is usable for the communications between radio apparatuses, from among the remaining part of the plurality of slots. A selection unit selects a slot from among the part of the plurality of slots in order to broadcast information on the detected slot. A modulation unit and an RF unit broadcast information on the slot detected by the empty slot identifying unit, using the selected slot. | 09-01-2011 |
| 20110228866 | BROADCASTING METHOD FOR SENDING SIGNAL CONTAINING PREDETERMINED INFORMATION AND RADIO APPARATUS - A control information extraction unit receives information on a frame that contains at least a plurality slots from an access control apparatus for controlling communications between radio apparatuses. The control information extraction unit generates a frame that contains at least a plurality of slots in such a manner as to synchronize with the frame corresponding to the received information. An estimation unit ( | 09-22-2011 |
| 20110299487 | BROADCASTING METHOD AND RADIO APPARATUS - A processing unit sets the time interval before packet signals are broadcast, using a carrier sense multiple access (CSMA) scheme. A modem unit and an RF unit broadcasts the packet signals at the time intervals set by the processing unit. The RF unit and the modem unit receive a control signal broadcast from an access control apparatus at a predetermined frequency. The processing unit sets the time interval, during which the control signal is receivable, to a time length shorter than the time interval for the remaining cases. | 12-08-2011 |
| 20120028662 | BROADCASTING METHOD AND RADIO APPARATUS - An RF unit receives periodically signals broadcast by other terminal apparatuses. When the quality of the signal received periodically is more deteriorated than a second threshold value even though the intensity of the signal received periodically is larger than a first threshold value, an identifying unit detects a malfunction in another terminal apparatus from which the signal received periodically by the receiver has been broadcast. A processing unit, a modem unit, the RF unit and an antenna each broadcasts a signal containing the detection result that the malfunction has been detected and information on a detected location. | 02-02-2012 |
