  • Patent number: 10117262
    Abstract: A method, a system and a device for reporting uplink pilot interference are provided, which are applied to time division duplex (TDD) system, and include: a base station measures uplink pilot time slot (UpPTS) interferences within respective cell portions; the base station transmits the uplink pilot time slot interferences, which carries the home cell portion IDs corresponding to the uplink pilot time slot interferences, to a radio network controller, and the radio network controller selects the transmitting position of the uplink pilot time slot for all cell portions according to the uplink pilot time slot interferences and the home cell portion IDs. The system realizes the reporting of the dedicated measurement in TDD system.

  • Patent number: 8768396
    Abstract: A method and apparatus for realizing power control on a control channel including measuring the interval between the current control channel transmission and the last control channel transmission; comparing the measured interval with a preset threshold, and if the interval is larger than or equal to the preset threshold, carrying out the current control channel transmission by using the initial transmit power, or controlling the current control channel transmission by using the open loop power control and, otherwise, controlling the current control channel transmission by using the closed loop power control. When the control channel is an uplink control channel, it may be determined whether a compensation for path loss variance should be added based on the closed loop power control according to a related command, so as to enable that the power control can be provided effectively when the control channel transmission is discontinuous.
