20100172307 | BASE STATION, WIRELESS COMMUNICATION SYSTEM, AND BANDWIDTH CONTROL METHOD - Burst intervals for transmitting and receiving user data of each mobile station provided in downlink subframes and uplink subframes prescribed by orthogonal frequency division multiple access are divided in the frequency axis direction into a plurality of allocated regions that correspond to the number of sectors; allocated regions for transmitting and receiving user data of each mobile station are allocated to allocated regions that correspond to the sector in which the mobile station is located; and when the allocated bandwidth required for transmission of user data in a sector surpasses the communication bandwidth of the allocated region, an allocated region is allocated that corresponds to a sector other than that sector. | 07-08-2010 |
20110039549 | RADIO COMMUNICATION SYSTEM, BASE STATION, RADIO COMMUNICATION METHOD, AND PROGRAM - A radio communication system includes a terminal and a base station that reports power information in that base station to the terminal. The base station includes: a report period control unit that controls the period of reporting power information in its own base station to be a first period during normal operation and, when its own base station is the handover target of the terminal, controls the report period to be a second period that is shorter than the first period in a fixed interval that follows completion of a handover preparation phase in which a data path for the terminal is generated with a network; and a report unit that reports power information in its own base station to the terminal at the controlled report period. | 02-17-2011 |
20110039550 | RADIO COMMUNICATION SYSTEM, BASE STATION, TERMINAL, RADIO COMMUNICATION METHOD AND PROGRAM - A radio communication system of the present invention includes a terminal and a base station.

20110051690 | RADIO COMMUNICATION SYSTEM, BASE STATION, TERMINAL, RADIO COMMUNICATION METHOD, AND PROGRAM - A radio communication system includes a terminal and a base station that reports power information in the base station to the terminal. The terminal includes a prediction unit that, at the time of handover, predicts the timing at which power information is to be reported next based on the report period for reporting power information by the base station, and a switching unit that, at the time of handover, carries out switching to a handover target base station before the timing that was predicted. | 03-03-2011 |
20110058507 | WIRELESS COMMUNICATION SYSTEM, BASE STATION, CHANNEL ALLOCATION METHOD, AND PROGRAM - A wireless communication system according to the present invention includes a terminal and a base station for forming a plurality of sectors and receiving an uplink subframe from said terminal positioned in any of said plurality of sectors, according to an OFDMA/TDD scheme. Here, in said uplink subframe, said base station allocates a predetermined subchannel among subchannels usable by said base station to two predetermined sectors among said plurality of sectors in said uplink subframe, according to time division. | 03-10-2011 |
20110255435 | RADIO COMMUNICATION SYSTEMS, BASE STATIONS, RADIO COMMUNICATION METHODS, AND PROGRAMS - A base station according to the present invention includes a decision unit that computes an allowable throughput of each terminal for each of combinations of modulation systems and code rates in the case in which the base station accommodates a predetermined accommodation number of terminals in advance, compares a minimum reserved traffic rate of the terminal that is the control target and the allowable throughput, and decides a minimum physical rate at which the bandwidth is reserved based on the compared results; and a control unit that executes the control for the terminal that is the control target postulating that the adaptive modulation is executed for the terminal that is the control target at the minimum physical rate decided by the decision unit. | 10-20-2011 |
