Question: In DC-HSDPA and DB-DC-HSDPA modes, how is a cell uniquely identified for a User Equipment (UE) receiving two cells simultaneously?
Option 1: By a unique combination of scrambling code and carrier frequency.
Option 2: Solely by the scrambling code assigned to each cell.
Option 3: Exclusively by the carrier frequency of each cell.
Option 4: Through a dedicated identifier sent in the broadcast channel.
Explanation: In the context of DC-HSDPA and DB-DC-HSDPA, identifying cells accurately is crucial for simultaneous reception. The correct approach involves a combination of unique identifiers - specifically, the scrambling code (distinguishing cells at the same frequency) and the carrier frequency (differentiating cells operating on different frequencies), ensuring precise cell recognition for efficient simultaneous data transmission and reception.
