Claim 6:
7. The method according to claim 1, wherein responsive to determining that the parameter related to the current channel quality comprises the RSRQ, the obtaining, by the terminal device, the current channel quality comprises:
measuring, by the terminal device, a downlink signal to obtain a value of the RSRP;
detecting, by the terminal device, a signal in a receive bandwidth, to obtain a value of a reference signal strength indicator (RSSI); and
performing, by the terminal device, a calculation based on the value of the RSRP and the value of the RSSI, according to a second preset formula, to obtain a value of the RSRQ, wherein the second preset formula comprises: RSRQ=N*RSRP/RSSI, and N is a quantity of subcarriers in the receive bandwidth.
