need to know the value of the n_ho_rb and function f_hop , depending on the formula. However, since the second time slot does not take the image of the PRB location has been determined, we can use this to reverse the introduction of N_HO_RB and f_hop values, and then you can calculate the second time slot in the mirror mode after the PRB location. Here is the calculation process:(Figure 9) from the above results, you can see that after the predefined frequency hopping pattern and image pattern
