POWER CONTROL METHOD AND TERMINAL EQUIPMENT

摘要

A user equipment includes: a processor circuit coupled with a transmitter, the processor circuit configured to, drop a Sounding Reference Signal (SRS) transmission when a total transmission power exceeds maximum output power of the user equipment and the user equipment needs to transmit a Physical Random Access Channel (PRACH) signal in a secondary serving cell in parallel with the SRS transmission in a same orthogonal frequency division multiplexing symbol of a different serving cell; and adjust transmission power of a physical uplink channel signal until an adjusted total transmission power is less than or equal to the maximum output power of the user equipment when the user equipment needs to transmit a PRACH signal in a secondary serving cell and transmit a physical uplink channel signal in other serving cell(s) within a symbol.
