20090067376 | PACKET TRANSMISSION CONTROL DEVICE, AND PACKET TRANSMISSION CONTROL METHOD - A disclosed packet transmission control apparatus that controls packet transmission to plural radio terminals includes a priority determination portion that determines a packet assignment priority in accordance with at least one of presence/absence of retransmission data and the number of data transmissions, and a radio terminal selection portion that selects a radio terminal to be a communications party in accordance with the priority. | 03-12-2009 |
20090215484 | WIRELESS COMMUNICATION CONTROL SYSTEM, RADIO BASE STATION AND WIRELESS COMMUNICATION CONTROL METHOD - A radio communication control system controlling a transmission power of a shared control channel for transmitting a control signal to a plurality of mobile stations. The system includes a transmission power lower limit value setting section configured to set a lower limit value of the transmission power of the shared control channel, and to set the transmission power of the shared control channel at the lower limit value when the transmission power of the shared control channel is lower than the lower limit value. | 08-27-2009 |
20110134892 | RADIO BASE STATION AND RADIO RESOURCE ALLOCATION METHOD - A radio base station of the present invention is provided with an index setting unit configured to set an index to a radio resource in a frequency domain, a resource allocation class determining unit is configured to determine a resource allocation class of a radio communication terminal from among resource allocation classes which are classified according to radio resource allocation patterns fixedly allocated at a fixed time interval T | 06-09-2011 |
20110205975 | MOBILE COMMUNICATION SYSTEM, MOBILE STATION AND RADIO BASE STATION - In a mobile communication system according to the present invention, a mobile station (UE) is configured to transmit uplink data to a radio base station (eNB) by using an uplink radio resource allocated by the radio base station (eNB). The mobile station (UE) is configured to report an amount of data remaining in a transmission buffer of the mobile station (UE) to the radio base station (eNB) by use of the allocated uplink radio resource, upon completion of a predetermined number of times of allocation of the uplink radio resource to the mobile station (UE) by the radio base station (eNB). | 08-25-2011 |
20110207467 | BASE STATION, UPPER NODE, RADIO COMMUNICATION SYSTEM AND RADIO COMMUNICATION METHOD - A base station includes a scheduling unit and a call reception control unit. The call reception control unit includes a managing unit that updates total resource usage amount based on total resource allocation amount and manages the total resource usage amount, and a decision unit that adds an initial radio resource to be allocated to a new call to the total resource usage amount and decides whether the new call can be accepted. The managing unit updates the total resource usage amount by subtracting a radio resource in response to the release of an existing call that radio resource allocation being not controlled at each transmission time interval. The managing unit manages the total resource usage amount without subtracting a radio resource in response to the release of an existing call that radio resource allocation being controlled at each transmission time interval. | 08-25-2011 |
