Configurations of TDD：定义了具体的帧结构以SCS30Khz为例：

• DL：SL：UL=7:1:2，special slot=6：4：4

The set-up of physical channels for transmitter tests shall be according to one of the NR FR1 test models (NR-FR1TM) below. A reference to the applicable test model is made within each test.

The following general parameters are used by all NR test models:

- Duration is 1 radio frame (10 ms) for FDD and 2 radio frames for TDD (20 ms)

- The slots are numbered 0 to 10′2μ?– 1 where μ is the numerology corresponding to the subcarrier spacing

- NRB?is the maximum transmission bandwidth configuration seen in table 5.3.2-1 in TS?38.104?[2].

- Normal CP

- Virtual resource blocks of localized type

For FR1-TDD?without NB-IoT operation in NR in-band, test models are derived based on the uplink/downlink configuration as shown in the table 4.9.2.2-1 using information element TDD-UL-DL-ConfigCommon as defined in TS?38.331?[19].
