Question: What information does the E-DCH TDD Information LCR (Layer Configuration Request) IE convey in UTRAN's Iur interface RNSAP signalling, aside from scheduling info?
Option 1: UE logical channel parameters and Node B transmission power settings
Option 2: Handover preparation details and UE capability update triggers
Option 3: UE physical layer category, Node B processing overload level & power offset, and E-DCH retransmission settings
Option 4: Cell ID and serving RNC (Radio Network Controller) location area code
Explanation: The correct answer is Option 3 because the E-DCH TDD Information LCR IE carries detailed information about the UE's physical layer capabilities, the Node B's current processing load and its associated power offset, as well as settings for handling retransmissions on the Enhanced Dedicated Channel (E-DCH) in TDD mode, crucial for efficient radio resource management and scheduling decisions in UTRAN networks.
