Abstract
A reception apparatus (10) includes plural antennas (101, 102) that are compatible with an LTE communication scheme and one reception processing section (100) processing a reception signal acquired by any one of the plural antennas (101, 102).
Claims7
A reception apparatus comprising:
- plural antennas configured to be compatible with a long-term evolution (LTE) communication scheme;
- one reception processing section configured to process a reception signal acquired by any one of the plural antennas;
- a signal quality measurement section configured to use, as a first trigger, detection of a synchronization signal used during an initial cell search, to calculate a signal quality value indicative of quality of the reception signal acquired by a corresponding one of the antennas used during the initial cell search;
- and
- a control section configured to:
- perform switching of the antenna to another one of the antennas based on the signal quality value being less than a specific threshold, and
- use, as a second trigger, lack of detection of the synchronization signal for a given period of time during the initial cell search, to perform switching between the antennas.
4 more elements
An antenna control method, comprising:
- by a computer,
- using, as a first trigger, detection of a synchronization signal used during an initial cell search, to calculate a signal quality value indicative of quality of a reception signal acquired by an antenna used during the initial cell search;
- and
- performing switching the antenna to another antenna in a case where the signal quality value is less than a predetermined threshold;
- and
- using, as a second trigger, lack, for a given period of time, of detection of the synchronization signal used during the initial cell search, to perform switching between the antennas.
