Abstract
A full-duplex relay enhances the end-to-end spectral

efficiency compared to a half-duplex relay, provided that the

loop-back interference at relays is managed well. In order to

study the feasibility of the full-duplex relay, it is crucial to

measure and model the loop-back interference channels. This

paper presents a measurement campaign of these channels for

outdoor-to-indoor communications. A compact relay antenna

was developed to serve as a signal repeater between outdoor

base stations and indoor users, and was used for the loop-back

interference channel measurement. Measurement results revealed

that the mean interference level was -48 dB in the... (More)

was developed to serve as a signal repeater between outdoor

base stations and indoor users, and was used for the loop-back

interference channel measurement. Measurement results revealed

that the mean interference level was -48 dB in the compact

relay antenna, and it could be further reduced by placing the

outdoor and indoor antennas in a different position referred to as

a separate relay. Combined with an appropriate countermeasure

to reduce the interference level, such as an interference canceller,

the full-duplex operation of indoor compact relay terminal was

found to be feasible. (Less)
