Question: For a Base Station (BS) capable of multi-band operation, what additional parameter(s) must the manufacturer declare if the rated total output power and total number of supported carriers are **not simultaneously supported** for each operating band?
Option 1: Only the reduced total output power at the maximum number of supported carriers.
Option 2: Both the reduced number of supported carriers at the rated total output power **and** the reduced total output power at the maximum number of supported carriers.
Option 3: The supported operating band combinations of the BS and the total number of supported carriers for these combinations.
Option 4: The maximum RF bandwidth of each supported operating band in multi-band operation.
Explanation: When a Base Station (BS) is capable of multi-band operation but cannot simultaneously support its rated total output power and the maximum number of carriers, the manufacturer must provide detailed declarations to clarify the BS's operational limitations. This includes specifying how many fewer carriers can be supported at full power (reduced number of supported carriers at the rated total output power) and conversely, how much less power is available when operating with the maximum number of carriers (reduced total output power at the maximum number of supported carriers). This ensures transparency on the BS's performance under different operational configurations.
