  • Patent number: 10291361
    Abstract: [Problem] To avoid the occurrence of a “DTX-ACK” error or “DTX-NACK” error when a terminal has failed to receive uplink control information. [Solution] A base station (20) of a wireless communication system wherein packet retransmission control is performed by means of a hybrid automatic repeat request (HARQ) is equipped with: a physical uplink shared channel (PUSCH) reception processing unit (104) that, when the transmission timing of HARQ information from a terminal (10) coincides with the transmission timing of a PUSCH transmitted from the terminal (10), receives the HARQ information from the PUSCH and performs a cyclic redundancy check (CRC) on a packet included in the PUSCH; and an HARQ information check unit (105) that performs HARQ-based confirmation of reception at the terminal (10) by receiving the HARQ information checked by the PUSCH reception processing unit (104) and the CRC result.

  • Patent number: 8848634
    Abstract: One object of the present invention is to make a base station detect inconsistency between an uplink maximum transmission power P_CMAX actually set by a mobile station, and a maximum transmission power P_EMAX allowed by the base station for the mobile station without making the mobile station report to the base station about a transmission power upper-limit value P_UMAX associated with a power class of the mobile station. A base station (10) determines inconsistency between a set value P_CMAX of a maximum transmission power which a mobile station (13) actually imposes on itself and an index value P_RMAX of the maximum transmission power used in the base station (10) for scheduling a radio resource carrying an uplink signal.

  • Patent number: 8107959
    Abstract: When a base station receives a report of signal power of a common pilot channel of each cell received at a mobile station, the base station converts the received signal power in the report on the basis of the transmission power of the common pilot channel of each of the cells. A base station controller determines the cell to which the mobile station is to be connected on the basis of the received signal power of the common pilot channel in each cell.

  • Publication number: 20090117894
    Abstract: In a wireless diversity reception apparatus, a combining unit RAKE-combines signals of multipaths transmitted from a mobile station and received by a plurality of antennas. An antenna failure detection unit detects an antenna failure based on selection result information representing paths used for RAKE combining. A mobile station control unit calculates the total reception power value of a cell in accordance with an antenna failure detection state and outputs power control information to make the total reception power value of the cell match a target total reception power value. A transmission unit transmits the power control information to the mobile station to perform transmission power control of the mobile station. A wireless diversity reception method is also disclosed.
