LTE Advanced—Future of Mobile Broadband
This paper provides an overview of some technology components currently considered for the evolution of LTE, referred to as LTE-Advanced. First, a brief overview of LTE Advanced requirements and expected indicative performances are discussed. One of the targets with the evolution of LTE is to reach or even surpass these requirements through features like extended spectrum flexibility to support up to 100MHz bandwidth, enhanced multi-antenna solutions with up to eight layer transmission in the downlink and up to four layer transmission in the uplink, coordinated multi-point transmission/reception,and the use of advanced repeaters/relaying. This paper then discusses each feature individually.
