Abstract: The technology described herein relates to determining transmit power of an uplink signal, to ensure uplink transmission performance of an new radio (NR) base station, and reduce impact on uplink transmission of a long term evolution (LTE) terminal. The technology includes receiving a message sent by a network device, where the message carries a first loss parameter related to a first uplink carrier and a second loss parameter related to a second uplink carrier, and calculating transmit power of an uplink signal. Where the uplink signal is sent on the first uplink carrier, the transmit power of the uplink signal can be calculated based on the first loss parameter related to the first uplink carrier. Where the uplink signal is sent on the second uplink carrier, the transmit power of the uplink signal can be calculated based on the second loss parameter related to the second uplink carrier.
