Question: In FDD mode, during a connection for non-HSDPA test cases, what is the specified relationship between the downlink Dedicated Physical Channel (DPCH) and another channel at the base station for measurement purposes?
Option 1: The DPCH precedes the other channel by 2 symbols in the slot structure.
Option 2: There is a fixed 5-chip offset between the start of the DPCH and the other channel.
Option 3: The DPCH overlaps with the first symbol of the other channel, with a zero-chip offset at the base station.
Option 4: The other channel starts exactly in the middle of the DPCH slot structure.
Explanation: This correct answer reflects the precise timing relationship specified for measurement purposes during non-HSDPA test cases in FDD mode. The zero-chip offset ensures that the DPCH and the other channel overlap at the beginning of the DPCH slot, which is crucial for accurate measurements and synchronization in the network. This setup is particularly important for assessing the performance and conformance of User Equipment (UE) in a controlled environment.
