The fifth generation (5G) of wireless networks features three core use cases, namely ultra-reliable and low latency communications (URLLC), massive machine type (mMTC), enhanced mobile broadband (eMBB). These cases co-exist in many practical scenarios compete for the same set time frequency resources, resulting a natural trade-off their performance. In this paper, network supporting both URLLC ...
Joint Activity Detection, Channel Estimation, and Data Decoding for Grant-free Massive Random Access
In the massive machine-type communication (mMTC) scenario, a large number of devices with sporadic traffic need to access network on limited radio resources. Recently, grant-free random has emerged as promising mechanism for this challenging but its potential not been fully unleashed. particular, available auxiliary information exploited, including common sparsity pattern in received pilot and ...
The core requirement of massive Machine-Type Communication (mMTC) is to support reliable and fast access for an enormous number machine-type devices (MTDs). In many practical applications, the base station (BS) only concerns list received messages instead source information, introducing emerging concept unsourced random (URA). Although some multiple-input multiple-output (MIMO) URA schemes have...
Fifth-generation mobile communication networks (5G)/Beyond 5G (B5G) can achieve higher data rates, more significant connectivity, and lower latency to provide various computing service categories, of which enhanced broadband (eMBB), massive machine-type communications (mMTC), ultra-reliable low (URLLC) are the three extreme cases. A symmetrically balanced mechanism must be considered in advance...
The Fifth Generation (5G) Network will bring different types of services, namely: EMBB, mMTC and URLLC as more devices connect to the network, each user device request for data capacity continue grow. increase in number require an network capacity, which also need Base Stations network. More Mobile Operator’s capital investment operation costs. However, this CAPEX OPEX not provide a correspondi...
While existing security protocols were designed with a focus on the core network, enhancement of B5G access network becomes critical importance. Despite strengthening 5G respect to LTE, there are still open issues that have not been fully addressed. This work is articulated around premise rethinking design bottom up, starting at physical layer, only viable in 6G but importantly, arises as an ef...
This paper presents a beyond 5G fronthaul network with dynamic beamforming and -steering. The proposed solution deploys optical (OBF) by combining space division multiplexing (SDM), analogue radio-over-fiber (ARoF), the novel beam forming (OBFN) technologies. From service management orchestration (MANO) point of view, also an advanced software defined networking (SDN) Network Function Virtualiz...
Device activity detection is one main challenge in grant-free massive access, which recently proposed to support machine-type communications (mMTC). Existing solutions for device fail consider inter-cell interference generated by IoT devices or important prior information on activities and interference. In this paper, given different numbers of observations network parameters, we both non-coope...
Wireless communications became an integrated part of the human life. Fifth generation (5G) is modern communication which provides enhanced mobile broadband (eMBB), ultra reliable low latency (URLLC), and massive machine type (mMTC). Thus, 5G have to provide coverage multi-numerology devices, therefore, modulation access schemes are suggested in literature such as cyclic prefix orthogonal freque...
Fifth-generation (5G) networks enable a variety of use cases that require differentiated connectivity, e.g., Ultra-Reliable and Low-Latency Communications (URLLC), enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC). To explore the full potential these cases, it is mandatory to understand communication along with 5G network segments architecture components. User Equipmen...
