Transport channels are characterized by how the data are transferred over the radio interface. Logical channels are characterized by the information that is transferred. Question-3: What are the LTE logical, transport and physical channels?Īnswer-3:All these channels help LTE UE establish the connection with the eNodeB, maintain theĬonnection and terminate the same.

Hence it consists of total 84 time/frequency elements referred as resource elements in LTE network.

One full resource block is equal to 12 subcarriers by 7 symbols in normal CP. One time slot is equal to 7 OFDM symbols in normal cyclic prefix and 6 OFDM symbols in extended cyclic prefix. It is of about 0.5ms duration and composed of 12 subcarriers in 1 OFDM symbol. Resource block is the smallest unit of resource allocation in LTE system. Question-2: What is resource block in LTE?Īnswer-2:LTE frame is divided based on time slots on time axis and frequency subcarrier on frequency axis. In TDD, one single frequency will be used at different time instants by multiple subscriber terminals (UEs).īoth frame versions of LTE will have 1 ms sub-frame duration and 0.5 ms slot duration. In FDD there will be pair of frequencies assigned in the downlink and uplink directions and hence transmissions from multiple subscribes can happen at the same time but on different frequencies as mentioned. Question-1: What is the difference between LTE FDD and LTE TDD?Īnswer-1:The difference lies in the LTE frame structure in both the FDD and TDD versions of the LTE.

These questions are very useful as viva questions also. One can refer page links mentioned on left side panel to learn more about LTE. These top 12 LTE interview questions and answers help engineers seeking LTE technology job to crack LTE and LTE advanced technology is fast evolving in cellular arena and demand in the industries have been increased for LTE skilledĮngineers.
