Displays the frequency hopping status of the UE specific sounding reference signals Configuration.
This is read only parameter and automatically decided as below.
There is a relation among SRS Bandwidth (B_SRS), SRS Hopping Bandwidth (b_hop) and Frequency Hopping.
Frequency Hopping On: (b_hop) < (B_SRS)
Frequency Hopping Off: (b_hop) >= (B_SRS)
