摘要： A wireless base station (100) calculates a first transmission rate when performing transmission to a wireless terminal with communication path quality by a first transmission power in a first candidate band selected as a candidate from first wireless bands including a neighboring priority band, calculates a second transmission rate when performing transmission to the wireless terminal (200) with the communication path quality by a second transmission power in a second candidate band selected as a candidate from second wireless bands that do not include the neighboring priority band, and sets, out of a first wireless resource including the first transmission power and the first candidate band and a second wireless resource including the second transmission power and the second candidate band, a wireless resource for a higher transmission rate obtained by the calculation as a wireless resource allocatable to the wireless terminal (200). It is therefore possible to maximize the throughput of the wireless terminal existing in the local station communication area while implementing suppression of interference to the neighboring cell.

摘要： When a downlink communication channel quality is informed of in the downlink packet communication using a shared channel, the communication channel quality for each RB that is obtained by dividing a downlink into a plurality of small bands (RBs) is informed of via the uplink. As the downlink band is getting wider, the number of RBs increases and the bands required to inform via the uplink also increases. Then, in the mobile station, RBs whose the communication channel quality is at a predetermined threshold or more are selected as a selected group, with the others considered as in the non-selected group, the information indicating which groups do they belong to is generated as a bitmap, and then the average value, the minimum value and the maximum value of the communication channel quality of the RBs are also obtained. Then the minimum or the maximum value is transmitted as a represented value of the selected group, the average value is transmitted as a representative value of the non-selected group, and also the bitmap is transmitted to the base station. At the base station, the communication channel quality for each RB is restored by replacing the communication channel quality belonging to the selected group by the minimum or the maximum value, and the communication channel quality belonging to the non-selected group by the average value.

摘要： There is provided a mobile communication system that can prevent a situation in which, although there is no occasion to receive packets for a mobile station, the reception processing is continued and useless power is undesirably consumed. The mobile communication system includes a base station that repeats a transmission period and a transmission halt period with a constant control cycle, and mobile station that repeats a reception period and a reception halt period with a constant control cycle (antenna, duplexer, reception unit, user data separation unit, packet transmission determination unit, reception period determination unit, packet reception determination unit, and signal synthesis unit). The mobile station alternately repeats the reception period and reception halt period, sends the reception result to the base station, and starts the reception period according to the start of the transmission period of the base station to receive packets. In case all the packets cannot be correctly received during the reception period, the reception period is extended by a predetermined period in the control cycle. Furthermore, in case all the packets can be correctly received during the reception period, the mobile station transfers to the reception halt period to halt the reception.
