3GPP Physical Layer Formulas
SLOT DURATION
T_slot = 1 / (2μ × 14) ms
Where μ is SCS config (0=15kHz, 1=30kHz, 2=60kHz, 3=120kHz, 4=240kHz)
SYMBOL DURATION
T_symbol = T_slot / 14
Each slot contains 14 OFDM symbols (normal CP)
GUARD PERIOD
T_GP = N_GP × T_symbol
GP prevents DL-to-UL interference. N_GP configured per special slot format.
TDD 时隙格式说明
3GPP TS 38.213 Table 11.1.1-1 定义了 TDD 时隙格式。每个时隙包含 14 个 OFDM 符号（普通 CP），每个符号可配置为下行 (D)、上行 (U) 或灵活 (F)。灵活符号通常用作 Guard Period 以防止下行到上行的干扰。
常见的 5G TDD 配置（如 DDDSU 模式）在下行吞吐量和上行延迟之间取得平衡。 运营商可根据业务需求选择不同的时隙格式和 TDD 模式组合。
