Question: What is the basis for determining the receiver characteristics of the Enhanced Physical Downlink Control Channel (EPDCCH) in terms of error probability?
Option 1: Probability of false detection of the Downlink Scheduling Grant (Pf-dsg)
Option 2: Probability of miss-detection of the Physical Control Format Indicator Channel (PCFICH)
Option 3: Block Error Rate (BLER) of the EPDCCH
Option 4: Probability of miss-detection of the Downlink Scheduling Grant (Pm-dsg)
Explanation: The receiver characteristics of the EPDCCH are determined by the probability of miss-detection of the Downlink Scheduling Grant (Pm-dsg), which is a key performance metric for evaluating the reliability of the EPDCCH transmission. This probability reflects the likelihood that the UE will fail to detect the scheduling grant, leading to potential errors in downlink data reception.
