In this paper the benefits provided by multi-cell processing of signalstransmitted by mobile terminals which are received via dedicated relayterminals (RTs) are assessed. Unlike previous works, each RT is assumed here tobe capable of full-duplex operation and receives the transmission of adjacentrelay terminals. Focusing on intra-cell TDMA and non-fading channels, asimplified uplink cellular model introduced by Wyner is considered. Thisframework facilitates analytical derivation of the per-cell sum-rate ofmulti-cell and conventional single-cell receivers. In particular, the analysisis based on the observation that the signal received at the base stations canbe interpreted as the outcome of a two-dimensional linear time invariantsystem. Numerical results are provided as well in order to provide furtherinsight into the performance benefits of multi-cell processing with relaying.
