LTE / LTE-A (4G) has been the fasted implemented new mobile communication technology to date. Even though LTE R12 is not mainstream in the networks today and R13 is currently being standardized the search for “whatever comes after LTE” – already termed 5G – is heavily underway.

After a wrap-up of LTE, this course discusses why LTE is not suited for the envisaged use cases of 5G. Assuming the 5G use cases, possible requirements can already be formulated and the consequences illustrated. An overview of current research activities is given with a status on possible new air interface candidates.
