example 1

[0178] Example 1, if at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna has at least one antenna whose transmit power is greater than or equal to the first antenna, then the first target antenna is at least one current transmit power threshold greater than or equal to The smallest of the current transmit power thresholds corresponding to the antennas of the first transmit power.

[0179] In implementation, when the user terminal detects that the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there are antennas other than the first antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna When using an antenna with a transmit power threshold, the user terminal may determine whether there is an antenna with a current transmit...

[0181] Example 2, if at least one antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna, the current transmit power thresholds of each antenna are smaller than the first transmit power antenna, then the first target antenna is at least one current transmit power threshold The largest of the current transmit power thresholds of the antennas among the antennas greater than the current transmit power threshold of the first antenna.

[0182] In implementation, when the user terminal detects that the first transmit power is greater than the current transmit power threshold of the first antenna to which the first radio frequency signal currently belongs, and there are antennas other than the first antenna whose current transmit power threshold is greater than the current transmit power threshold of the first antenna When using an antenna with a transmit power threshold, the user terminal may determine whether the curr...

Abstract

The embodiment of the invention provides a method and device for improving uplink performance and a user terminal, and relates to the technical field of communication. The method comprises the following steps: acquiring first transmitting power corresponding to one or more first radio frequency signals to be transmitted; when the first transmitting power is greater than a current transmitting power threshold value of a first antenna to which the first radio frequency signal currently belongs and when at least one antenna, except the first antenna, in the at least two antennas has at least oneantenna of which the current transmitting power threshold value is greater than the current transmitting power threshold value of the first antenna, determining a first target antenna of which the first current transmitting power threshold is closest to the first transmitting power forward direction from at least one antenna of which the current transmitting power threshold is greater than the current transmitting power threshold of the first antenna; determining first target transmitting power according to the first transmitting power and a first current transmitting power threshold; transmitting one or more first radio frequency signals to be transmitted through the first target antenna according to the first target transmitting power. The uplink performance of the user terminal is improved.
