Rate-splitting multiple access (RSMA) has been recognized as a promising physical layer strategy for 6G. Motivated by the ever-increasing popularity of cache-enabled content delivery in wireless communications, this paper proposes an innovative multigroup multicast transmission scheme based on RSMA for cache-aided cloud-radio access networks (C-RAN). Our proposed scheme not only exploits the properties of content-centric communications and local caching at the base stations (BSs) but also…

Power Minimization Using Rate Splitting With Statistical CSI in Cloud-Radio Access Networks

This paper considers a cloud-radio access network (C-RAN) model where a central processor (CP) is connected to the base stations (BSs) via limited capacity fronthaul links and considers that the CP applies the rate splitting (RS) strategy by dividing each user’s message into two parts.

Interference Management Strategies for Multiuser Multicell MIMO VLC Systems

Analytical results illustrate the flexibility and superiority of the proposed precoding strategies for RSMA over conventional coordinated space division multiple access and non-orthogonal multiple access for different scenarios and network loads.



Rate Splitting Multiple Access in C-RAN: A Scalable and Robust Design

This paper investigates the problem of stochastic coordinated beamforming (SCB) optimization to maximize the ergodic sum-rate (ESR) in the network and proposes a scalable and robust RS scheme where the number of the common streams to be decoded at each user scales linearly with thenumber of users, and the common stream selection only depends on the statistical CSI.

Interference Mitigation via Rate-Splitting and Common Message Decoding in Cloud Radio Access Networks

This paper focuses on maximizing the weighted sum-rate subject to per-BS backhaul capacity and transmit power constraints, so as to jointly determine the RS-CMD mode of transmission, the cluster of BSs serving private and common messages of each user, and the associated beamforming vector design and clustering.

In a C-RAN model where theRRHs are connected to the CP via multihop routers, data-sharing can be superior to compression if the network coding technique is adopted for multicasting user messages to the cooperating RRHs, and the RRH's beamforming vectors are jointly optimized based on the techniques of sparse optimization and successive convex approximation.

Content-Centric Sparse Multicast Beamforming for Cache-Enabled Cloud RAN

This paper presents a content-centric transmission design in a cloud radio access network by incorporating multicasting and caching, and reformulates an equivalent sparse multicast beamforming (SBF) problem, transformed into the difference of convex programs and effectively solved using the convex-concave procedure algorithms.

An Efficient Rate-Splitting Multiple Access Scheme for the Downlink of C-RAN Systems

This letter studies the optimization of rate-splitting multiple access (RSMA) transmission technique for a cloud radio access network (C-RAN) downlink system and shows the performance gains of the proposed RSMA scheme over conventional space-division multiple access and non-orthogonal multiple access schemes as well as over a conventionalRSMA scheme that uses a single common signal.

Power Minimization Via Rate Splitting in Downlink Cloud-Radio Access Networks

An iterative approach based on inner-convex approximations (ICA) to obtain a stationary point of the optimization problem and show the power savings achieved by the proposed RS-CMD scheme as compared to the conventional TIN, especially at high QoS requirements.

Cloud Radio Access Networks With Coded Caching

This work introduces local storage caches at the BSs, in which the popular files are stored locally in order to reduce the load of the backhaul links, and utilizes coded caching with the goal to minimize the total network cost.

Rate-Splitting for Multi-Antenna Non-Orthogonal Unicast and Multicast Transmission: Spectral and Energy Efficiency Analysis

Numerical results show that the proposed RS-assisted NOUM transmission strategies are more spectrally and energy efficient than the conventional Multi-User Linear-Precoding (MU–LP), Orthogonal Multiple Access (OMA) and power-domain NOMA in a wide range of user deployments.

The MMF Degrees-of-Freedom (DoF) achieved by RS and NoRS in multigroup multicast with imperfect CSIT is characterized and a generic transmit power constrained optimization problem is formulated to achieve MMF rate performance.

Rate-splitting multiple access for downlink communication systems: bridging, generalizing, and outperforming SDMA and NOMA

RSMA is a more general and more powerful multiple access for downlink multi-antenna systems that contains SDMA and NOMA as special cases that relies on linearly precoded rate-splitting with SIC to decode part of the interference and treat the remaining part of The capability of RSMA to partially decode interference and partially treat interference as noise enables to softly bridge the two extremes.
