Question: In a 5G E-UTRA network, what is the maximum supported PUSCH channel bandwidth for a User Equipment (UE) operating in Coverage Enhancement Mode B?
Option 1: 1.4 MHz and 5 MHz (dependent on UE Category)
Option 2: 5 MHz
Option 3: 20 MHz
Option 4: 1.4 MHz
Explanation: According to the specifications for E-UTRA, when a User Equipment (UE) is operating in Coverage Enhancement Mode B, the maximum supported PUSCH channel bandwidth is specifically defined as 1.4 MHz, highlighting the bandwidth constraints for uplink communications under this mode to ensure reliable connectivity in areas with poor coverage.
