Long Term Evolution Advanced (LTE-A) is defined in 3GPP Release 10 and is intended to be the first fully compliant version of the ITU’s specification for 4G systems. The targeted peak rate for downlink is 1 Gbps and, for uplink, greater than 500 Mbps. This should be achieved with scalable usage of up to 100 MHz spectrum. LTE-A should support various cell types, including pico and femto, to improve uplink speeds as well as relay technologies to improve coverage. Furthermore, LTE-A should be backward compatible to LTE, Release 8.
