Performance of Decentralized Interference Coordination in the LTE Uplink

Abstract: Interference management techniques like inter-cell interference coordination (ICIC) will play a key role in enabling high spectral efficiency in future wireless OFDMA-based cellular systems. The aim of ICIC is to lower inter-cell interference by coordinating the usage of spectrum resources among neighboring cells. Especially for the cell-edge users, avoiding the reuse of the same resources in neighboring cells yields a significant increase in SINR and thus capacity. In this paper, we consider decentralized ICI… Show more

“…Eventually, a general steady state among non-cooperative selfish agents can be reached among structure, namely the Nash equilibrium [98], where each individual can achieve resource sharing without reducing its competitiveness. Some major contributions can be found in [96] [97]. However, the main challenge here is to devise a user utility function in convex form that favors inter-cell interference management in the long term.…”

“…The designed solutions start with fixed soft and fractional frequency reuse schemes [47,48] and ranges through different kinds of dynamic distributed and autonomous coordination schemes [49,50]. The common characteristic of all those solutions is the minimization of interference perceived by UEs and hence focuses on controlling the A2A type of interference.…”

“…In [55], a decentralized, game-theoretic approach is proposed, whereby each eNB iteratively selects a set of PRBs that minimizes its own perceived interference from its neighbours. At each allocation instance, a new set of PRBs is selected with a certain probability if the perceived interference can be reduced by a specified threshold.…”
