Abstract:
1. A bandwidth configuration method, comprising: acquiring, by a terminal, that a narrow bandwidth mode is used at a network side by a downlink transmission signal and/or an uplink transmission signal; and configuring, by the terminal, a receiving bandwidth and/or a transmitting bandwidth, wherein the receiving bandwidth and/or the transmitting bandwidth corresponds to the narrow bandwidth mode at the network side such that the receiving bandwidth and/or the transmitting bandwidth can be adjusted at the terminal side when the narrow band width is used at the network side; wherein acquiring, by the terminal, that the narrow bandwidth mode is used at the network side by the downlink transmission signal comprises: obtaining, by the terminal, passband average power of the downlink transmission signal and transition band average power of the downlink transmission signal in predetermined time; and if a ratio between the passband average power of the downlink transmission signal and the transition band average power of the downlink transmission signal is smaller than a predetermined threshold, acquiring that the narrow bandwidth mode is used at the network side by the downlink transmission signal.
