Abstract
A base station broadcasts information of an entire discontinuous signal transmission duration and information of a discontinuous signal transmission interval to a plurality of terminals, and stops transmission of a downlink control signal and data for at least some interval of the discontinuous signal transmission interval.
Claims17
A method of controlling signal transmission in a base station comprising a transmitter configured to transmit signal frames, the method comprising:
- broadcasting information of an entire discontinuous signal transmission duration and information of a discontinuous signal transmission interval to all terminals in a cell;
- and
- stopping transmission of a downlink control signal, a pilot signal, and data traffic except for a preamble signal and a system information message for the discontinuous signal transmission interval to the terminals in the cell,
- wherein the terminals in the cell do not perform any receiving operations except for the preamble signal and the system information message during the discontinuous signal transmission interval.
A signal transmission control apparatus of a base station, comprising:
- a transmitter configured to transmit signal frames, and further configured to broadcast information of an entire discontinuous signal transmission duration and information of a discontinuous signal transmission interval to which zero energy is allocated to all terminals in a cell;
- and
- a transmission controller configured to stop signal transmission of a downlink control signal, a pilot signal, and data traffic, except for a downlink preamble interval and a system information transmission interval of the discontinuous signal transmission interval to the terminals in the cell,
- wherein the terminals in the cell do not perform any receiving operations except for the preamble signal and the system information message during the discontinuous signal transmission interval.
A method of controlling signal transmission in a base station comprising a transmitter transmitting signal frames, the method comprising:
- broadcasting information of a discontinuous signal transmission duration including a discontinuous signal transmission interval to all terminals in a cell;
- and
- not transmitting 1) a downlink control signal, a pilot signal, and data traffic, 2) the downlink control signal, a pilot signal, and data traffic except for a preamble signal for synchronization, or 3) the downlink control signal, a pilot signal, and data traffic except for the preamble signal and a system information message, to the terminal during the discontinuous signal transmission interval to the all terminals in the cell,
- wherein the terminals in the cell do not perform any receiving operations except for the preamble signal and the system information message during the discontinuous signal transmission interval.
