Note 1: UE assumes that the TCI state for the PDSCH is identical to the TCI state applied for the PDCCH transmission. Note 2: Point A coincides with minimum guard band as specified in Table 5.3.3-1 from TS 38.101-1 for tested channel bandwidth and subcarrier spacing. Note 3: For FR1 MIMO OTA test lab alignments and FR1 MIMO OTA UE performance requirements, the following values can be used: For FR1 bands >1GHz: 20k for 30kHz SCS, 10k for 15kHz SCS; For FR1 bands <1GHz: [20k] for 15kHz SCS; |
