name: ENBW
full_form: The aggregated bandwidth of an E-UTRA sub-block and an adjacent NR sub-block
context: 6.5B.2.1.3.1 Test purpose To verify that UE transmitter does not cause unacceptable interference to adjacent channels in terms of Adjacent Channel Leakage Power Ratio (ACLR). 6.5B.2.1.3.2 Test applicability This test case applies to all types of E-UTRA UE release 15 and forward, supporting intra-band contiguous EN-DC. 6.5B.2.1.3.3 Minimum conformance requirements For EN-DC operation with an E-UTRA sub-block immediately adjacent to an NR sub-block, the ACLR is defined as the ratio of the filtered mean power centred on the aggregated sub-block bandwidth ENBW to the filtered mean power centred on an adjacent bandwidth of the same size ENBW at nominal channel spacing. The UE shall meet the ACLR minimum requirement EN-DCACLR specified in Table 6.5B.2.1.3.3-1 with ENBW the sum of the sub-block bandwidths. The assigned channel power and adjacent channel power are measured with rectangular filters with measurement bandwidths specified in 6.5B.2.1.3.3-1. Table 6.5B.2.1.3.3-1: ACLR for
description: ENBW represents the aggregated bandwidth of an E-UTRA sub-block and an adjacent NR sub-block. It is used in calculating the Adjacent Channel Leakage Power Ratio (ACLR) for intra-band contiguous EN-DC operation.
explanation: ENBW is a specific value used in a technical calculation (ACLR), making it a parameter within the telecommunications system.
