name: SUL
full_form: Supplementary uplink
context: Insertion loss for TX and RX Figure 5.2.3.2.2-1 shows provisional results for the attenuation from TX to the antenna. It is noted that the results are indicative: they are based simulations and not representing a final product. All traces are "typical" at 25 C. About 2.5 MHz allowance at either end of the pass band needs to be made for performance over temperature and process variation. Figure 5.2.3.2.2-2 shows provisional results for the attenuation from the antenna to the RX.

The corresponding results from antenna to RX are shown in Figure 5.2.3.2.2-4.

description: Supplementary Uplink (SUL) is a technology feature in the 5G New Radio (NR) system designed for supplementary uplink transmissions. It is being studied and standardized under Release 17 of the 3GPP specifications, focusing on various band combinations and configurations to enhance uplink capabilities.
explanation: The text explicitly describes SUL as a technology feature within the 5G NR system, highlighting its role in improving uplink transmissions. The mention of standardization under 3GPP Release 17 and focus on band configurations further solidify its classification as a Technology entity.
