“…Without time sharing, the transmission scheme described above boils down to turning off one transmitter during the whole transmission. Besides being highly unfair to one user, 2 Notation: P i k is the transmit power used by user k in time slot i. this would also result in lower achievable rates since the remaining two transmitters are only allowed to transmit with power P S . More specifically, the achievable sum rate in this case is…”

Throughput and energy efficiency in 3-way relay channels are studied in this paper. Unlike previous contributions, we consider a circular message exchange. First, an outer bound and achievable sum rate expressions for different relaying protocols are derived for 3-way relay channels. The sum capacity is characterized for certain SNR regimes. Next, leveraging the derived achievable sum rate expressions, cooperative and competitive maximization of the energy efficiency are considered. For the cooperative case, both low-complexity and globally optimal algorithms for joint power allocation at the users and at the relay are designed so as to maximize the system global energy efficiency. For the competitive case, a game theoretic approach is taken, and it is shown that the best response dynamics is guaranteed to converge to a Nash equilibrium. A power consumption model for mmWave board-to-board communications is developed, and numerical results are provided to corroborate and provide insight on the theoretical findings.

“…Channel measurements and a link budget for such a system with 4-by-4 antenna arrays are given in [2]. Since there is no mobility in this scenario, the beams have a fixed direction and the antenna array combined with the beamforming network can be regarded as a single antenna with a gain of 7 dB.…”

“…The distances that need to be covered are in the range of a few centimeters at most. Each link shall support a data rate of up to 100 Gbit s −1 [4]. A Butler Matrix beam switching network for an operational frequency of 180 GHz has already been designed [5].…”
