Peak-Throughput of LTE-Release 10 for Up/Down Link Physical Layer

Abstract

Long Term Evolution (LTE) Release 8 of the Universal Mobile Telecommunications Systems (UMTS) was developed to provide extensive support for deployment in a variety of spectrum allocations, ranging from 1.4 MHz to 20 MHz, for both paired and unpaired bands. For system bandwidth beyond 20 MHz, the only reasonable way to achieve LTE-Advanced highest target peak-throughput rate is to increase the transmission bandwidth, relative to Release 8. In order to provide the necessary bandwidth, LTEAdvanced specifies spectrum allocations of up to 100 MHz using “carrier aggregation”, where multiple component carriers are combined. Therefore, to configure all component carriers that are LTE Release 8 compatible, at least when the aggregated numbers of component carriers in the Uplink (UL) and the Downlink (DL) must be the same. However, not all component carriers are necessarily Release 8 compatible. The main aim of this paper is to investigate a comprehensive analysis of physical layer throughput of LTEAdvanced (DL) and (UL) using Multi Input Multi Output channel (MIMO) 2x2 based on standard parameters for different channel bandwidths.
