Although in cellular networks full duplex and dynamic time-division duplexing promise increased spectrum efficiency, their potential is so far challenged by interference. While previous studies have shown that self-interference can be suppressed to a sufficient level, we show the cross-link interference for both modes, especially from base station station, remaining challenge multi-cell network...

in this paper we consider the non-preemptive variant of a multi-mode resource constrained project scheduling problem (mrcpsp) with mode identity, in which a set of project activities is partitioned into disjoint subsets while all activities forming one subset have to be processed in the same mode. we present a depth-first branch and bound algorithm for the resource constrained project schedulin...

Single-pole double-throw (SPDT) switches are a key building block for enabling transceiver time-division duplexing (TDD) when operated as a T/R switch or for eliminating imager fluctuations when operated as a Dicke switch. To provide acceptable compromises of NF, Pout and sensitivity in transceivers or imagers, the switches are required to feature an insertion loss of ~3dB and an isolation of ~...

Coexistence of different access technologies, hierarchical cellular deployment, a wide variety of data services, requirements for transparent operation across different technologies, adaptivity to varying network conditions and mobility and Quality of Service (QoS) constraints introduce a number of challenges in the design of future generation systems and the specification of new air interfaces...

This paper considers several aspects concerning the downlink channel adaptation for TDD (Time Division Duplexing) based LMDS (Local Multipoint Distribution System) systems. First the requirements with respect to round-trip-time and complexity are considered, then a candidate scheme for the Forward Error Correction (FEC) scheme is described. The results of a simulation study of the performance o...

This paper investigates the power allocation for upstream and downstream signals in twisted-pair channels in order to maximize data rate. The channels interfere with each other in two forms: the near-end crosstalk and far-end crosstalk. These interferences can be mitigated by the joint optimization of upstream and downstream power spectral density (PSD). We derive the condition under which a su...

This paper presents a new Time Division Multiple Access/Frequency Division Duplexing (TDMA/FDD) based Medium Access Control (MAC) protocol for broadband wireless networks, supporting Quality of Service (QoS) for real-time multimedia applications. It also gives the Call Blocking Probability (CBP), packet end-to-end delay and utilization analysis of different service classes, as they are most ess...

The trend for dense deployment in future 5G mobile communication networks makes current wired backhaul infeasible owing to the high cost. Millimetre-wave (mm-wave) communication, a promising technique with the capability of providing a multi-gigabit transmission rate, offers a flexible and cost-effective candidate for 5G backhauling. By exploiting highly directional antennas, it becomes practic...
