TL;DR: It is shown that there is a capacity gain for SU under the average over the peak transmit/interference power constraint and that fading for the channel between SU transmitter and PU receiver is usually a beneficial factor for enhancing the SU channel capacities.

TL;DR: This paper investigates price-based resource allocation strategies for the uplink transmission of a spectrum-sharing femtocell network, in which a central macrocell is underlaid with distributed femtocells, all operating over the same frequency band as the macrocell.

TL;DR: It is shown that the SU can achieve a significant capacity gain under the proposed model, compared with that under the opportunistic spectrum access or the conventional spectrum sharing model.

TL;DR: In this paper, a wireless communication network with a full-duplex hybrid energy and information access point and a set of wireless users with energy harvesting capabilities is considered, where the causal dependence of each user's harvesting time on the transmission time of earlier users is modeled by assuming that energy harvested in the future cannot be used for the current transmission.

TL;DR: It is shown by simulations that the derived new power allocation strategies can achieve substantial capacity gains for the secondary user over the conventional methods based on the interference temperature (IT) constraint, with the same resultant primary user outage probability.
