To ensu re competitiveness of UMTS for the next 10 years and beyond, UMTS Long Term Evolution (LTE) has been introduced in 3GPP release 8. LTE, which is also known as Evolved UTRA and Evolved UTRAN, provides new physical layer concepts and protocol architecture for UMTS. This application note introduces LTE FDD and TDD technology and testing aspects.
