4.8.2 Applicability of test configurations for single-band RIB
The applicable test configurations are specified in the tables below for each the supported RF configuration, which shall be declared according to clause 4.6. The generation and power allocation for each test configuration is defined in clause 4.7. This clause contains the test configurations for single-band RIB.
For an IAB node declared to be capable of single carrier operation only, a single carrier (SC) shall be used for testing.
For a single-band RIB declared to support multi-carrier and/or CA operation in contiguous spectrum operation, the test configurations in the second column of table 4.8.2-1 shall be used for testing.
For a single-band RIB declared to support multi-carrier and/or CA operation in contiguous and non-contiguous spectrum and where the parameters in the manufacturer’s declaration according to clause 4.6 are identical for contiguous (C) and non-contiguous (NC) spectrum operation, the test configurations in the third column of table 4.8.2-1 shall be used for testing.
For a single-band RIB declared to support multi-carrier and/or CA in contiguous and non-contiguous spectrum and where the parameters in the manufacture’s declaration according to clause 4.6 are not identical for contiguous and non-contiguous spectrum operation, the test configurations in the fourth column of table 4.8.2-1 shall be used for testing.
For a single-band RIB declared to support multi-carrier and/or CA and IAB simultaneous operation (D.x) in contiguous and non-contiguous spectrum and where the parameters in the manufacture’s declaration according to clause 4.6 are identical for contiguous and non-contiguous spectrum operation, the test configurations in the third column of table 4.8.2-2 shall be used for testing.
For a single-band RIB declared to support multi-carrier and/or CA and IAB simultaneous operation (D.x) in contiguous and non-contiguous spectrum and where the parameters in the manufacture’s declaration according to clause 4.6 are not identical for contiguous and non-contiguous spectrum operation, the test configurations in the fourth column of table 4.8.2-2 shall be used for testing.
Unless otherwise stated, single carrier configuration (SC) tests shall be performed using signal with narrowest supported IAB-DU or IAB-MT channel bandwidth with the smallest supported subcarrier spacing declared per operating band (D.7).
