Revisiting Data Recovery Loops in 6G Networks

no code implementations11 Apr 2024 Uyoata E. Uyoata, Abolfazl Amiri, Enric Juan, Guillermo Pocovi, Pilar Andres-Maldonado, Klaus I. Pedersen, Troels Kolding

In this paper, we evaluate the interaction between a fast hybrid automatic repeat request (HARQ) scheme, present in the physical and medium access control layers, and a higher layer automatic repeat request (ARQ) scheme which may be present in the radio link control layer.

Extended Reality over 3GPP 5G-Advanced New Radio: Link Adaptation Enhancements

no code implementations26 Oct 2022 Pouria Paymard, Abolfazl Amiri, Troels E. Kolding, Klaus I. Pedersen

One of the rapidly emerging services for fifth-generation (5G)-Advanced is eXtended Reality (XR) which combines several immersive experiences and cloud gaming services.

Enhanced Link Adaptation for Extended Reality Code Block Group based HARQ Transmission

no code implementations25 Aug 2022 Pouria Paymard, Abolfazl Amiri, Troels E. Kolding, Klaus I. Pedersen

Extended Reality (XR) is one of the most important media applications in 5\textsuperscript{th} Generation (5G) and 5G-Advanced.

Uncoordinated and Decentralized Processing in Extra-Large MIMO Arrays

no code implementations11 Mar 2021 Abolfazl Amiri, Carles Navarro Manch'on, Elisabeth de Carvalho

We propose a decentralized receiver for extra-large multiple-input multiple-output (XL-MIMO) arrays.

Antenna Selection for Improving Energy Efficiency in XL-MIMO Systems

no code implementations5 Sep 2020 José Carlos Marinello, Taufik Abrão, Abolfazl Amiri, Elisabeth de Carvalho, Petar Popovski

We consider the recently proposed extra-large scale massive multiple-input multiple-output (XL-MIMO) systems, with some hundreds of antennas serving a smaller number of users.

Distributed Receivers for Extra-Large Scale MIMO Arrays: A Message Passing Approach

no code implementations14 Jul 2020 Abolfazl Amiri, Sajad Rezaie, Carles Navarro Manchon, Elisabeth de Carvalho

In this paper, we propose a distributed receiver for such an XL-MIMO system that can address both challenges.

Low-Complexity Distributed XL-MIMO for Multiuser Detection

1 code implementation31 Jan 2020 Victor Croisfelt Rodrigues, Abolfazl Amiri, Taufik Abrão, Elisabeth de Carvalho, Petar Popovski

In this paper, the zero-forcing and regularized zero-forcing schemes operating in crowded extra-large MIMO (XL-MIMO) scenarios with a fixed number of subarrays have been emulated using the randomized Kaczmarz algorithm (rKA).
