Question: In a multi-band Base Station (BS) operation with high PSD per carrier (UTC4), how are additional carriers placed within each band after initial placement at the outermost edges of the declared Maximum Radio Bandwidth?
Option 1: Randomly across the remaining bandwidth to maximize capacity.
Option 2: At the center of the band to minimize interference.
Option 3: Not placed, as only edge placement is specified for multi-band operations.
Option 4: At the Base Station RF Bandwidth edges, if possible, following the initial edge placement.
Explanation: According to the UTC4 configuration rules for multi-band testing with high PSD per carrier, after placing carriers at the outermost edges of the declared Maximum Radio Bandwidth, additional carriers are placed at the Base Station RF Bandwidth edges if possible. This approach ensures efficient use of bandwidth while considering the constraints of multi-band operation, thus reflecting a nuanced understanding of 3GPP's specifications for base station conformance testing in complex operational scenarios.
