This document presents a comprehensive analysis of spectrum emission mask test results for the N77d band, conducted by TCT Testing Centre Technology. The tests cover various configurations, including Single-Input Single-Output (SISO) transmissions, Cyclic Prefix Orthogonal Frequency Division Multiplexing (CP-OFDM), and Discrete Fourier Transform-Spread-OFDM (DFT-S-OFDM) modulation schemes. The tests were performed under Non-Terrestrial Network Validation (NTNV) conditions.
The report includes detailed spectrum plots and tabular data, showcasing the emission levels at different frequency offsets from the carrier. The results are evaluated against regulatory limits to ensure compliance. Specific test parameters include channel bandwidths of 70MHz, 80MHz, 90MHz, and 100MHz, using Quadrature Phase-Shift Keying (QPSK) modulation. The analysis covers edge and inner 1RB (Resource Block) configurations, as well as outer full bandwidth scenarios. The tests were conducted on both left and right antenna ports.
The data presented in this report is crucial for verifying the spectral purity of the N77d band transmissions, ensuring minimal interference with adjacent frequency bands. The report provides valuable insights for optimizing transmitter performance and meeting regulatory requirements.
