Performance Analysis of Layer 1 Relays
Jun Jia Zheng, Philippe Sartori, Bing Wei · 2009
Relays are expected to be included in 3GPP Release 10 also known as LTE-Advanced (LTE-A). Relays can be used to improve coverage and throughput and could be an important tool to improve the wireless experience. In this paper, the discussion on relay technologies in 3GPP LTE-A is overviewed firstly. Because both low cost and small delay make LI relay more attractive than other types of relay, the SINR and information rate performance of LI relays are analyzed mainly in this paper. With a simple one-dimensional relay model and an approximate self-interference model, the capability of LI relays to improve cell-edge throughput is verified.
