We consider an adaptive co-primary spectrum sharing scheme based on playing one-shot games between co-located distributed Radio Access Networks (RANs). Spectrum is divided into private and shared parts, and each RAN internally applies coordinated multi-point transmissions. Zero-forcing precoding is used in the private part, while unitary precoding is applied in the non-orthogonally shared part. A...
Currently mobile network operators are allocated spectrum bands on an exclusive basis. While this approach facilitates interference control, it may also result in low spectrum utilization efficiency. Inter-operator spectrum sharing is a potential method to enhance spectrum utilization. In order to realize it, a protocol to coordinate the actions of operators is needed. In this paper, we propose a...
We investigate a non-cooperative interference canceling and power control (IC-PC) game in a Gaussian interference channel, where the receivers are able to process at most two codewords at a time. We characterize the equilibria of this game. As opposed to the pure power control game and the rate splitting game between the same players, we find that in the IC-PC game, there exist Nash equilibria where...
