Question: In a static environment, what metric determines the receive characteristic of a Dedicated Channel (DCH) in a User Equipment (UE), and how is this channel typically mapped for transmission?
Option 1: Signal-to-Noise Ratio (SNR) - DCH is mapped into the Shared Channel (SCH)
Option 2: Frame Error Rate (FER) - DCH is mapped into the Dedicated Physical Control Channel (DPCCH)
Option 3: Block Error Ratio (BLER) - DCH is mapped into the Dedicated Physical Channel (DPCH)
Option 4: Bit Error Rate (BER) - DCH is mapped into the Random Access Channel (RACH)
Explanation: The correct answer, Option 3, accurately reflects that in a static environment, the receive characteristic of a Dedicated Channel (DCH) for a User Equipment (UE) is determined by the Block Error Ratio (BLER), which is specified for each individual data rate of the DCH. Furthermore, it correctly states that the DCH is mapped into the Dedicated Physical Channel (DPCH) for transmission. This highlights the importance of BLER in assessing the reliability of data transmission over dedicated channels in wireless communications, particularly in conformance testing to ensure UEs meet specified standards for different data rates.
