Path loss model comparison for LTE-Advanced relay backhaul link in urban environment

Relaying technology is a key technical enhancement in 3GPP LTE-Advanced developed in order to improve the throughput for cell-edge users. Power-balanced path loss models for the links Base Station-Relay Station (BS-RS), Base Station-Mobile Station (BS-MS) and Relay Station-Mobile Station (RS-MS) are required to evaluate relaying system performances. This paper presents a measurement-based study which aims to compare Path Loss (PL) models for...
