Claim 7:
8. The method according to claim 1, wherein responsive to determining that the parameter related to the current channel quality comprises the RS-CINR, 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 third preset formula, to obtain a value of the RS-CINR, wherein the third preset formula comprises: RS-CINR=N*RSRP/(RSSI−N*RSRP) and N is a quantity of subcarriers in the receive bandwidth.
