In this paper, we present a new cooperative communication scheme consisting of two users in half-duplex mode communicating with one destination over a discrete memoryless channel. The users encode messages in independent blocks and divide the transmission of each block into 3 time slots with variable durations. Cooperation is performed by partial decode-forward relaying over these 3 time slots. During the first two time slots, each user alternatively transmits and decodes, while during the last…

Throughput-Optimal Half-Duplex Cooperative Scheme with Partial Decode-Forward Relaying

A cooperative communication system consisting of two users in half duplex mode communicating with one destination over additive white Gaussian noise shows significant improvement of the rates when the inter-user channel quality is better than that between each user and the destination.

Achievable Rates and Outer Bound for the Half-Duplex MAC with Generalized Feedback

Numerical results for the Gaussian channel shows significant rate region improvement over the classical MAC and that the outer bound becomes increasingly tight as the inter-user link quality increases.

Rate Maximization for Half-Duplex Multiple Access with Cooperating Transmitters

Results show that as the inter-user link qualities increase, the optimal scheme moves from no cooperation to partial then to full cooperation, in which the users fully exchange their information and cooperatively send it to the destination.

Joint typicality analysis for half-duplex cooperative communication

This work proposes a half-duplex cooperative scheme for a discrete memoryless channel (DMC) consisting of two users communicating with one destination that uses joint typicality instead of maximum likelihood (ML) decoding to derive the rate region.

Outage analysis for half-duplex partial decode-forward relaying over fading channels

Spectral Efficiency and Outage Performance for Hybrid D2D-Infrastructure Uplink Cooperation

A time-division uplink transmission scheme that is applicable to future-generation cellular systems by introducing hybrid device-to-device (D2D) and infrastructure cooperation significantly reduces outage probabilities and achieves the full diversity order despite additional outages at the UEs.

Efficient use of joint source-destination cooperation in the Gaussian multiple access channel

Uplink User-Assisted Relaying in Cellular Networks

It is shown that user-assisted relaying can significantly improve per-user transmission rate despite of increased intercell interference, and this transmission rate gain is significant for active users near the cell edge and further increases with higher idle user density, supporting user- assisted relaying as a viable solution to crowded population areas.

It is shown that cooperation can increase the achievable secrecy region, and achievable schemes which use compress-and-forward (CAF) based transmission strategies are proposed which allow users to increase their rates up to levels which are not decodable by the cooperating partners, consequently improving the secrecy of the users.
