    摘要： A communication system, a terminal apparatus, a base station apparatus, and a method for sharing a codebook are provided that make it possible to improve system capacity by using precoding according to a cell environment. In a communication system in which beam directivity control is performed by precoding using a codebook that is common between a base station (10) and a terminal (20), the base station (10) notifies the terminal (20) information for codebook determination k including cell (11)-specific information on the base station, and the base station (10) and the terminal (20) generate the common codebook based on the information for codebook determination.

    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.

    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.
