METHODS AND APPARATUS OF SRS POWER CONTROL FOR COHERENT JOINT TRANSMISSION

Title:

METHODS AND APPARATUS OF SRS POWER CONTROL FOR COHERENT JOINT TRANSMISSION

Document Type and Number:

WIPO Patent Application WO/2024/073970

Kind Code:

A1

Abstract:

Methods and apparatus of SRS power control for coherent joint transmission are disclosed. The apparatus includes a receiver that receives a signalling for indicating enhanced Sounding Reference Signal (SRS) power control parameters; a processor that determines a transmission power for an SRS based on the enhanced SRS power control parameters; and a transmitter that transmits the SRS with the determined transmission power.
