Abstract
[Object] To make it possible to suppress deterioration in communication quality of radio communication in a small cell while power consumption of a base station of the small cell is reduced. [Solution] Provided is a communication control device including: an acquisition unit configured to acquire a result of measurement performed by a terminal device with regard to one or more small cells which are partly or entirely overlapped by a macrocell; and a selection unit configured to select a base station which is not to be set in an idle state from base stations of the one or more small cells based on the result of the measurement.
Claims12
A communication control device comprising:
- circuitry configured to
- control base stations of one or more small cells which are partly or entirely overlapped by a macrocell to transmit signals for measurement by a terminal device and decide a timing at which each of the signals is transmitted in accordance with a time taken for a corresponding one of the base stations to be activated from an idle state;
- transmit small cell information to the terminal device, the small cell information comprising a list including the timing at which each of the signals is transmitted and information that indicates a frequency channel at which each of the signals is transmitted;
- acquire a result of the measurement performed by the terminal device with regard to said one or more small cells;
- and
- select a base station which is not to be set in the idle state from base stations of the one or more small cells based on the result of the measurement.

A communication control method comprising:
- controlling base stations of one or more small cells which are partly or entirely overlapped by a macrocell to transmit signals for measurement by a terminal device and deciding a timing at which each of the signals is transmitted in accordance with a time taken for a corresponding one of the base stations to be activated from an idle state;
- transmitting small cell information to the terminal device, the small cell information comprising a list including the timing at which each of the signals is transmitted and information that indicates a frequency channel at which each of the signals is transmitted;
- acquiring a result of the measurement performed by the terminal device with regard to said one or more small cells;
- and
- selecting, using a processor, a base station which is not to be set in the idle state from base stations of the one or more small cells based on the result of the measurement.

A communication control device comprising:
- circuitry configured to
- control transmission of a signal for measurement performed by a terminal device with regard to a small cell which is partly or entirely overlapped by a macrocell and decide a timing at which the signal is transmitted in accordance with a time taken for a base station of the small cell to be activated from an idle state;
- transmit small cell information to the terminal device, the small cell information comprising a list including the timing of the signal and information that indicates a frequency channel at which the signal is transmitted;
- and
- refrain from causing the base station of the small cell to be in an idle state when the base station of the small cell is selected as a base station that is not to be set in the idle state based on a result of the measurement.

A terminal device comprising:
- circuitry configured to
- receive signals from base stations of one or more small cells which are partly or entirely overlapped by a macrocell, each of the signals being received at a timing decided in accordance with a time taken for a corresponding one of the base stations to be activated from an idle state;
- receive small cell information comprising a list including the timing at which each of the signals is received and information that indicates a frequency channel at which each of the signals is transmitted;
- determine a result of measurement with regard to the one or more small cells;
- and
- provide the result of the measurement to a communication control device which selects a base station which is not to be set in the idle state from the base stations of the one or more small cells based on the result of the measurement.
