A.1.1 IAB-DU Reference measurement channels

The Annex A in TS 38.141-1 [13] applies to FR1 IAB-DU.

A.1.2 IAB-MT Reference measurement channels

A.1.2.1 Fixed Reference Channels for reference sensitivity level, ACS, in-band blocking, out-of-band blocking and receiver intermodulation (QPSK, R=1/3)

The parameters for the reference measurement channels are specified in tables A.1.2.1-1 for FR1 reference sensitivity level, ACS, in-band blocking, out-of-band blocking, receiver intermodulation, OTA sensitivity, OTA reference sensitivity level, OTA ACS, OTA in-band blocking, OTA out-of-band blocking, and OTA receiver intermodulation.

NOTE 1: DL-DMRS-config-type = 1 with DL-DMRS-max-len = 1, DL-DMRS-add-pos = pos2 with = 2, = 6 and 9 as per Table 7.4.1.1.2-3 of TS 38.211 [9].

NOTE 2: MCS index 4 and target coding rate = 308/1024 are adopted to calculate payload size for receiver sensitivity

NOTE 3: Code block size including CRC (bits) equals to cid:image005.png@01D6459A.4A6FCF50 in sub-clause 5.2.2 of TS 38.212 [10].
