Question: What are the primary purposes of the two formats supported by the Narrowband Physical Uplink Shared Channel (NPUSCH) in E-UTRA?
Option 1: NPUSCH Format 1 for uplink control information and NPUSCH Format 2 for UL-SCH (Uplink Shared Channel)
Option 2: NPUSCH Format 1 for UL-SCH and NPUSCH Format 2 for both uplink control information and supplementary UL-SCH
Option 3: Both NPUSCH Formats are exclusively used for carrying different types of uplink control information
Option 4: NPUSCH Format 1 is used to carry the UL-SCH, while NPUSCH Format 2 is specifically designed to carry uplink control information
Explanation: The correct answer highlights the distinct purposes of NPUSCH's two formats: Format 1 for carrying User Equipment's (UE) uplink data via the UL-SCH and Format 2 for transmitting crucial uplink control information, key to efficient resource allocation and signaling in wireless communication networks.
