Center node: "decentralized simultaneous energy and information transmission in multiple access channels"
  Abstract: In this report, the fundamental limits of decentralized simultaneous information and energy transmission in the two-user Gaussian multiple access channel (G-MAC) are fully characterized for the case in which a minimum energy transmission rate $b$ is required for successful decoding. All the achievable and stable information-energy transmission rate triplets $(R_1, R_2, B)$ are identified. $R_1$ and $R_2$ are in bits per channel use measured at the receiver and $B$ is in energy units per channel use measured at an energy-harvester (EH). Stability is considered in the sense of an $\eta$-Nash equilibrium (NE), with ${\eta}\geqslant 0$ arbitrarily small. The main result consists of the full characterization of the $\eta$-NE information-energy region, i.e., the set of information-energy rate triplets $(R_1,R_2,B)$ that are achievable and stable in the G-MAC when: $(a)$ both transmitters autonomously and independently tune their own transmit configurations seeking to maximize their own information transmission rates, $R_1$ and $R_2$ respectively; $(b)$ both transmitters jointly guarantee an energy transmission rate $B$ at the EH, such that $B \geqslant b$. Therefore, any rate triplet outside the ${\eta}$-NE region is not stable as there always exists one transmitter able to increase by at least ${\eta}$ bits per channel use its own information transmission rate by updating its own transmit configuration.
