In this paper, we describe CoMP2flex, a user-centric base station (BS) cooperation scheme that provides improvements in reliability of both uplink (UL) and downlink (DL) communications of wireless cellular networks. CoMP2flex supports not only cooperation of two BSs with same direction of traffic but also cooperation of two BSs serving bidirectional traffic. The reliability performance of CoMP2flex...
The source coding problem with action-dependent side information at the decoder has recently been introduced to model data acquisition in resource-constrained systems. In this paper, an efficient Blahut-Arimoto-type algorithm for the numerical computation of the rate-distortion-cost function for this problem is proposed. Moreover, a simplified two-stage code structure based on multiplexing is put...
We address the problem of radio resource allocation in the Downlink (DL) of a cellular system with multiple Relay Stations (RS), based on Orthogonal Frequency Division Multiple Access (OFDMA) transmission technology. The design of efficient resource allocation algorithms for such a system is crucial, in order to exploit the potential capacity and coverage increase offered by the relays. We propose...
