Abstract

A user equipment includes: a transmitter configured to transmit uplink signals; and a processor circuit coupled with the 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 symbol on a subframe of a different serving cell; and adjust transmission power of a Physical Uplink Shared Channel (PUSCH) 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 in parallel with a PUSCH signal in a different serving cell within a symbol.

Claims (5)

1. A user equipment comprising:

a transmitter configured to transmit uplink signals; and

a processor circuit coupled with the 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 symbol on a subframe of a different serving cell; and

adjust transmission power of a Physical Uplink Shared Channel (PUSCH) 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 in parallel with a PUSCH signal in a different serving cell within a symbol.
