This report, prepared by SGS-CSTC Standards Technical Services (Suzhou) Co., Ltd., presents a comprehensive analysis of the occupied bandwidth for various configurations within the N77 (3700-3980 MHz) frequency band. The tests were conducted to ensure compliance with regulatory standards, focusing on different modulation schemes, channel bandwidths, and antenna configurations.
The report details the test setup, including the use of a spectrum analyzer to measure the occupied bandwidth under various conditions. The configurations tested include DFT-QPSK, DFT-PI2BPSK, DFT-16QAM, DFT-64QAM, DFT-256QAM, and CP-QPSK modulations, each evaluated with different outer full resource block allocations. The tests were performed on PC1 with various antenna ports (Ant0, Ant1) to assess the impact of MIMO configurations on the occupied bandwidth.
The results are presented in a series of spectrum plots, each showing the occupied bandwidth, center frequency, and frequency offset for a specific configuration. The plots include key parameters such as the reference level, offset, resolution bandwidth (RBW), video bandwidth (VBW), and sweep time. Marker tables provide detailed measurements of the occupied bandwidth, including the lower and upper frequency limits, and the corresponding power levels.
The report concludes that all tested configurations comply with the specified occupied bandwidth limits, as indicated by the "PASS" designation for each test case. This comprehensive analysis provides valuable insights into the spectral characteristics of the N77 band under various operating conditions.
