A method, which is applied to a UE, for controlling the transmission power of each of positioning (POS) sounding reference signals (SRSs) across a subset of multiple component carriers (CCs) in carrier aggregation is provided. A SRS configuration for a subset of the CCs is received. Pathlosses corresponding to SRS transmission in the subset of the CCs are measured. Pathloss measurements corresponding to the subset of the CCs are processed to obtain a single pathloss across the subset of the CCs. The transmission power of each of the POS-SRSs across the subset of the CCs is determined based on the single pathloss. Each of the POS-SRSs are transmitted with the transmission power through the CCs.
