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-ConfigCommonas defined in TS 38.331 [19].
