context: formation Four related UE capabilities were introduced: FG 16-4 Low PAPR DMRS for PDSCH FG 16-6a Low PAPR DMRS for PUSCH without transform precoding FG 16-6b Low PAPR DMRS for PUCCH format 3 and 4 with transform precoding and with pi/2 BPSK FG 16-6c Low PAPR DMRS for PUSCH with transform precoding and with pi/2 BPSK 2.5 Uplink (UL) full-power transmission Three modes of operation are specified in Rel.16 as optional UE capabilities: fullpower, fullpowerMode1, fullpowerMode2. The UE can report one of the supported modes. fullpower: This mode targets the UEs with full-rated PAs. Using a 2-Tx PC3 non-coherent UE as an example, the UE is equipped with two 23dBm PAs. As shown in Figure 9, the UE transmits UL PUSCH using 1 antenna when the indicated TPMI is {1 0} with Rel.16 power scaling factor s=1. This implies that the transmit power is equally split among non-zero PUSCH antenna(s) thereby enabling the UE to deliver maximum output power. Figure âfullpowerâ operation fullpowerMode1: A new
description: Binary Phase Shift Keying (BPSK) is a modulation technique used to transmit data over a communication channel. It involves shifting the phase of a carrier signal between two discrete values (0 and Ï radians) to represent binary data (0 and 1). BPSK is particularly suited for applications requiring low PAPR (Peak-to-Average Power Ratio), such as Reference Signals (RS) for Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH).
explanation: BPSK is classified as a Modulation Technique because its primary function is to encode binary data onto a carrier signal by altering the phase of the signal, as explicitly stated in the description.
