“…For example, adaptation is useless in some models [13]. For the multiple-input and multiple-output setting, it is also known that non-adaptive transmission achieves optimal degrees-of-freedom in some multi-way networks [19,Chap. 6].…”

Full-duplex communication allows a terminal to transmit and receive signals simultaneously, and hence, it is helpful in general to adapt transmissions to received signals. However, this often requires unaffordable complexity. This work focuses on simple non-adaptive transmission, and provides two classes of channels for which Shannon's information capacity regions are achieved without adaptation. The first is the injective semideterministic two-way channel that includes additive channels with various types of noises modeling wireless, coaxial cable, and other settings. The other is the Poisson two-way channel, for which we show that non-adaptive transmission is asymptotically optimal in the high dark current regime.

“…It has recently been established that adaptation is not needed to achieve capacity for a broad class of channels with certain symmetric properties [16]- [18]. A more detailed survey is provided in [19,Chap. 2].…”

“…Thus, it is interesting to study a dynamic payload allocation which minimizes the delay over such a channel. This work can also be extended towards studying the latency of multiway communications [31], [32], or the latency under different reliability metrics such as guaranteed MSE [33].…”

“…where respectively, H ij ∈ C Mj ×Mi is the channel (coefficient) matrix from node j to node i and z i, is a realization of the random Gaussian noise vector 1 This means that nodes 2 and 3 are not aware of s prior to encoding the -th transmission signal. However, through sensing their received signal they capture s during reception.…”

Multi-way and device-to-device (D2D) communications are currently considered for the design of future communication systems. Unmanned aerial vehicles (UAVs) can be effectively deployed to extend the communication range of D2D networks. To model the UAV-D2D interaction, we study a multi-antenna multi-way channel with two D2D users and an intermittently available UAV node. The performance in terms of sum-rate of various transmission schemes is compared. Numerical results show that for different ground environments, the scheme based on a combination of interference alignment, zero-forcing and erasure-channel treatment outperforms other schemes at low, medium and high SNRs and thus represents a viable transmission strategy for UAV-aided multi-way D2D networks.Index Terms-UAV, multi-way communication, D2D, interference alignment.
