“…However, the authors tackle the problem of the UE-to-UE interference from an information theoretic perspective, without relating to resource allocation and power control. Conversely, some works consider the joint subcarrier and power allocation problem [8] and the joint duplex mode selection, channel allocation, and power control problem [9] in FD networks. The cellular network model in [8] is applicable to FD mobile nodes rather than to networks operating in TNFD mode.…”

Abstract-Three-node full-duplex is a promising new transmission mode between a full-duplex capable wireless node and two other wireless nodes that use half-duplex transmission and reception respectively. Although three-node full-duplex transmissions can increase the spectral efficiency without requiring fullduplex capability of user devices, inter-node interference -in addition to the inherent self-interference -can severely degrade the performance. Therefore, as methods that provide effective self-interference mitigation evolve, the management of internode interference is becoming increasingly important. This paper considers a cellular system in which a full-duplex capable base station serves a set of half-duplex capable users. As the spectral efficiencies achieved by the uplink and downlink transmissions are inherently intertwined, the objective is to device channel assignment and power control algorithms that maximize the weighted sum of the uplink-downlink transmissions. To this end a distributed auction based channel assignment algorithm is proposed, in which the scheduled uplink users and the base station jointly determine the set of downlink users for fullduplex transmission. Realistic system simulations indicate that the spectral efficiency can be up to 89 % better than using the traditional half-duplex mode. Furthermore, when the selfinterference cancelling level is high, the impact of the user-to-user interference is severe unless properly managed.

“…The authors in [10] mitigate the intra-cell interference in 3NT via optimized channel and power allocation. However, the algorithms in [6], [10] require the knowledge of instantaneous mutual channel state information between interfering UEs, which is hard to estimate and/or communicate. A practical way to mitigate the intra-cell interference is to pair interfering UEs based on their statistical mutual channel conditions, which requires statistical studies for the intra-cell interference.…”

Abstract-This paper develops a mathematical paradigm to study downlink error rates and throughput for half-duplex (HD) terminals served by a full-duplex (FD) base station (BS). Particularly, we study the dominant intra-cell interferer problem that appears between HD users scheduled on the same FDchannel. The distribution of the dominant interference is first characterized via its distribution function, which is derived in closed-form. Assuming Nakagami-m fading, the probability of error for different modulation schemes is studied and a unified closed-form expression for the average symbol error rate is derived. To this end, we show the effective downlink throughput gain, harvested by employing FD communication at a BS that serves HD users, as a function of the signal-to-interference-ratio when compared to an idealized HD interference and noise free BS operation.Index Terms-Dominant interference, Gaussian noise, Laplace interference, Nakagami-m fading, error rate, throughput.

“…The authors in [8] proposed an interference alignment technique to eliminate the inter-user interference between the UEs pair coupled on the same channel. The authors in [11] mitigate the interuser interference via an optimal channel allocation and power control that maximizes the system performance. In addition, in [12], [13] the authors investigate the user scheduling and power allocation by maximizing the system sum rate.…”
