Question: Which of the following downlink transport channel types in E-UTRAN is characterized by a fixed, pre-defined transport format and a requirement to be broadcast in the entire coverage area of the cell, but does NOT support dynamic link adaptation or beamforming?
Option 1: Downlink Shared Channel (DL-SCH)
Option 2: Paging Channel (PCH)
Option 3: Broadcast Channel (BCH)
Option 4: Multicast Channel (MCH)
Explanation: The correct answer is Option 3, Broadcast Channel (BCH), because it is the only downlink transport channel type that matches all the given criteria: - Fixed, pre-defined transport format: BCH is characterized by a fixed, pre-defined transport format. - Requirement to be broadcast in the entire coverage area of the cell: This is also a characteristic of BCH. - Does NOT support dynamic link adaptation or beamforming: Unlike DL-SCH, which supports dynamic link adaptation and beamforming, BCH does not have these capabilities. PCH and MCH do not match all these specific criteria as closely as BCH does, especially regarding the lack of dynamic link adaptation and beamforming.
