We study in this paper a sub-optimal beamforming algorithm for the MISO interference channel based on interference pricing, defined as user's marginal decrease in its utility due to interference. An iterative approach is considered given a set of interference prices and beams. Combining the interference price from other users and channel state information, the transmitter can update the beams to maximize...
In cognitive radio networks, secondary users can share frequency spectrum with primary users, where the primary users charge secondary users for radio resource usage. Pricing schemes adopted by primary users is crucial to both primary users and secondary users. In this paper, we investigate three different pricing models in a cognitive network. Under the Bertrand competition, all sellers make decision...
In cognitive radio networks, primary users can share frequency spectrum with secondary users and charge secondary users for radio resource usage. For the primary user, the price determines its revenue. In this article, we first consider competitive pricing. Under competition, service providers offer the prices simultaneously or sequentially. Nash equilibrium and Stackelberg equilibrium have been obtained...
