Game-Theoretic Approach to Distributed Scheduling for Relay-Aided OFDMA Systems

Co-channel interference mitigation techniques in multi-cell OFDMA Relay-Based Cellular Networks: A survey

“…4(c), in each sector, in order to alleviate intra-sector interference, three different sub-bands are allocated to two RSs and one BS. For instance, when W1 is allocated to N B(1,1), W2 to N R(1,1,1), and W3 to N R (1,1,2) in the first sector, the whole frequency is allocated to each sector by the pattern of 1×3×1. Different frequency bands are shared by the RSs located near to one another.…”

“…In [1], a novel distributed scheduling scheme is proposed, which offers high QoS to MSs, and actively utilizes the frequency reuse based on the non-cooperative game theoretic framework [5]. Because the game theory obviously allows a distributed operation, simultaneous transmission can be successfully scheduled by each RS without the help of the BS.…”

“…Nowadays, since wireless communication is common, the user requirements for better data rate as well as improved quality of service (QoS) through cellular networks are increasing [1]. Many technologies have been suggested to fulfill these strengthened demands.…”

“…Consequently, to alleviate possible interferences in OFDMA RBCN, developing effective interference coordination mechanisms is important [6]. In OFDMA RBCN, quite a lot of methods have been proposed to prevent co-channel interference [1], [5] - [14]. In [5]- [6], [8]- [12] the authors try to keep a Frequency Reuse Factor (FRF) of one and proposed different algorithms to cope with interference coordination, while the authors [1], [7], [13]- [14] set a different FRF and developed various types of frequency reuse technique.…”
