Question11: The resource block of the PUCCH channel is in the middle of the uplink frequency band.

Question12: What are the raster map formats supported by Assistant? (multiple choice)

Question13: In the LTE network, TA is used for paging location management, so the smaller the TA planning, the better.

Question14: Which of the following are NAS EMM? (multiple choice)

Question15: In high-speed and poor SINR scenarios, which is the best adaptive transmission mode?
