摘要： A base station includes a determination unit that determines whether user equipment performs radio communication through a booster, based on delay time of a signal transmitted to and received from the user equipment; a target SIR setting unit that sets a target SIR to be compared to a received SIR for performing transmission power control based on the received SIR of an uplink signal from the user equipment; a transmission power control signal generating unit that generates, based on the target SIR and the received SIR, a transmission power control signal to be set for controlling transmission power of the user equipment; and a transmitter that transmits the transmission power control signal to the user equipment. When determination is made that the radio communication is performed through the booster, the target SIR is set to be less than or equal to a predetermined upper limit value.

摘要： A base station allocates a radio resource to a scheduling-target user based on a scheduling metric which is calculated for each of scheduling-target users and calculates the amount of available data for each user. When the radio resource is allocated to the scheduling-target user, the amount of data (Dassign) to be communicated using the allocated radio resource is subtracted from the amount of available data (Davailable) for the user. The amount of available data (Davailable) for each user within a cell is updated (min((Davailable+Dref), Dref)) to be less than or equal to a reference data amount in each control period (TAMBR). The scheduling-target user is selected based on the amount of available data for each user.

摘要： A radio base station includes a resource assignment unit for assigning a resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal to a first mobile station during a semi-persistent scheduling bearer setting process. The resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal is formed by a combination of a frequency direction resource and a code direction resource by which the first mobile station transmits a transmission acknowledgement signal after a predetermined timing from a timing of receiving downlink data, to the downlink data that has been scheduled by semi-persistent scheduling and has been transmitted via a downlink data channel. The resource assignment unit is configured to assign the resource candidate for transmitting a semi-persistent scheduling transmission acknowledgement signal to the first mobile station based on a number of assignments of predetermined resources formed by a combination of a frequency direction resource and a code direction resource.

摘要： A base station apparatus determines which mode of a subframe bundling mode (second mode) and a non-bundling mode (first mode) should be used by a user apparatus for communication, and reports a determination result. In the first mode, RTT period is a first period, and each of transmission and retransmission of the signal is performed every 1 TTI. In the second mode, RTT period is a second period that is longer than the first period, and each of transmission and retransmission of the signal is performed every plurality of TTIs. A radio resource to be used for retransmission is determined according to a first frequency hopping pattern in the first mode, and is determined according to a second frequency hopping pattern that is different from the first frequency hopping pattern in the second mode.
