Resource Allocation for Urllc and Embb Traffic in Uplink Wireless Networks

SSRN Electronic Journal, 2022
In this paper we consider two resource allocation problems of URLLC traffic and eMBB traffic in uplink 5G networks. We propose to divide frequencies into a common region and a grant-based region. Frequencies in the grant-based region can only be used by eMBB traffic, while frequencies in the common region can be used by eMBB traffic as well as URLLC ...

Ethambutol resistance in Mycobacterium tuberculosis: critical role of embB mutations [PDF]

Antimicrobial Agents and Chemotherapy, 1997
Ethambutol [(S,S')-2,2'-(ethylenediimino)di-1-butanol; EMB], is a first-line drug used to treat tuberculosis. To gain insight into the molecular basis of EMB resistance, we characterized the 10-kb embCAB locus in 16 EMB-resistant and 3 EMB-susceptible genetically distinct Mycobacterium tuberculosis strains from diverse localities by automated DNA ...

Satellite use cases and scenarios for 5G eMBB [PDF]

, 2018
This book chapter presents initial results available from the European Commission H2020 5G PPP Phase 2 project SaT5G (Satellite and Terrestrial Network for 5G). It specifically elaborates on the selected use cases and scenarios for satellite communications positioning in the 5G usage scenario of eMBB (enhanced Mobile Broadband), which appears the most ...

Interference-Aware Subcarrier Allocation for Massive Machine-Type Communication in 5G-Enabled Internet of Things

Sensors, 2019
Massive machine-type communication (mMTC) is investigated as one of three typical scenes of the 5th-generation (5G) network. In this paper, we propose a 5G-enabled internet of things (IoT) in which some enhanced mobile broadband devices transmit video ...

The gravitational wave background from star-massive black hole fly-bys [PDF]

, 2009
Stars on eccentric orbits around a massive black hole (MBH) emit bursts of gravitational waves (GWs) at periapse. Such events may be directly resolvable in the Galactic centre.

Cryo-EM snapshots of mycobacterial arabinosyltransferase complex EmbB2-AcpM2

Protein & Cell, 2020
Inhibition of Mycobacterium tuberculosis (Mtb) cell wall assembly is an established strategy for anti-TB chemotherapy. Arabinosyltransferase EmbB, which catalyzes the transfer of arabinose from the donor decaprenyl-phosphate-arabinose (DPA) to its ...

Low Complexity Polar Decoder for 5G Embb Control Channel [PDF]

IEEE Access, 2019
Polar codes have become the channel coding scheme for control channel of enhanced mobile broadband in the fifth generation (5G) communication systems. Belief propagation (BP) decoding of polar codes has the advantage of low decoding latency and high parallelism but suffers from high complexity. In this paper, a low complexity BP decoder is proposed for

Architectures and Key Technical Challenges for 5G Systems Incorporating Satellites [PDF]

, 2018
Satellite Communication systems are a promising solution to extend and complement terrestrial networks in unserved or under-served areas. This aspect is reflected by recent commercial and standardisation endeavours. In particular, 3GPP recently initiated

IRS-Aided Physical Layer Network Slicing for URLLC and eMBB

IEEE Access, 2021
5G and beyond 5G (B5G) wireless systems promise to support services with different requirements in the same network, as enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine type communication (mMTC ...

Network Slicing for URLLC and eMBB With Max-Matching Diversity Channel Allocation [PDF]

IEEE Communications Letters, 2020
This work considers the problem of radio resource sharing between enhanced mobile broadband (eMBB) and ultra-reliable and low latency communications (URLLC), two heterogeneous 5G services. More specifically, we propose the use of a max-matching diversity (MMD) algorithm to properly allocate the channels to the eMBB users, considering both heterogeneous
