Abstract
A method for enabling a base station to control adaptive reporting in a TDD environment according to one embodiment of the present invention comprises the steps of: transmitting, from a base station to a terminal, an information element including reporting-setting information comprising reporting cycle and reporting offset of channel state information; transmitting information of a UL-DL setting change to the terminal; and receiving the channel state information by using the reporting cycle and the reporting offset of the reporting-setting information corresponding to the changed UL-DL setting.
Claims15
A method for controlling adaptive reporting by a base station in a Time Division Duplexing (TDD) environment, the method comprising:
- transmitting an information element including reporting configuration information including a reporting periodicity and a reporting offset of channel status information, from the base station to a user equipment;
- transmitting information on an Uplink (UL)-Downlink (DL) configuration change, from the base station to the user equipment;
- and
- receiving the channel status information by using a reporting periodicity and a reporting offset of the reporting configuration information corresponding to the changed UL-DL configuration, by the base station.
A method for controlling adaptive reporting by a user equipment in a Time Division Duplexing (TDD) environment, the method comprising:
- receiving an information element including reporting configuration information including a reporting periodicity and a reporting offset of channel status information, from a base station by the user equipment;
- receiving information on an Uplink (UL)-Downlink (DL) configuration change, from the base station by the user equipment;
- and
- transmitting the channel status information by using a reporting periodicity and a reporting offset of the reporting configuration information corresponding to the changed UL-DL configuration, by the user equipment.
A base station for controlling adaptive reporting in a Time Division Duplexing (TDD) environment, the base station comprising:
- a control unit for generating an information element including reporting configuration information including a reporting periodicity and a reporting offset of channel status information;
- a transmission unit for transmitting the generated information element to a user equipment, and transmitting, to the user equipment, information on an Uplink (UL)-Downlink (DL) configuration change of the user equipment;
- and
- a reception unit for receiving a signal from the user equipment,
- wherein the control unit controls the reception unit to receive indicator information of the user equipment by using a reporting periodicity and a reporting offset of the reporting configuration information corresponding to the changed TDD UL-DL configuration.
A user equipment for controlling adaptive reporting in a Time Division Duplexing (TDD) environment, the user equipment comprising:
- a reception unit for receiving, from a base station, an information element including reporting configuration information including a reporting periodicity and a reporting offset of channel status information, and receiving, from the base station, information on an Uplink (UL)-Downlink (DL) configuration change;
- a transmission unit for transmitting a signal to the base station;
- and
- a control unit for controlling the transmission unit to transmit the channel status information by using a reporting periodicity and a reporting offset of the reporting configuration information corresponding to the changed UL-DL configuration.
