Publication number: 20260181558Abstract: Systems and method provide for uplink carrier aggregation (UL CA) that is configured for a User Equipment (UE), and transmissions on multiple UL carriers by one power amplifier (PA). When a base station (e.g., a gNB) indicates the UE should switch its UL waveform from Cyclic-Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM) to Discrete Fourier Transform Spread OFDM (DFT-S-OFDM) for Physical Uplink Shared Channel (PUSCH) transmission in one or more UL carriers, the base station expects that the UE transmit power on a particular carrier can be increased, the carrier for which a UL coverage issue (e.g., low signal strength, signal to noise ratio, interference, etc.) is found. UL waveform switching from CP-OFDM to DFT-S-OFDM can improve the lower bound of PCMAX, namely the total UE transmit power on UL carriers of intra-band CA.Type: ApplicationFiled: November 1, 2023Publication date: June 25, 2026Inventors: Ling Su, Chunhui Zhang
