Index Modulation–Aided Mixed Massive Random Access

open access: yesFrontiers in Communications and Networks, 2021
In this study, a mixed massive random access scheme is considered where part of users transmit both common information and user-specific information, while others transmit only common information.

D2D Assisted Q-Learning Random Access for NOMA-Based MTC Networks

open access: yesIEEE Access, 2022
Machine-type communications (MTC) should account for half the connections to the internet by 2030. The use case massive MTC (mMTC) allows for applications to connect a massive number of low-power and low-complexity devices, leading to challenges in ...

Random Beam-Based Random Access for Low-Latency Device-to-Device Communication Systems

open access: yesIEEE Access, 2020
In this paper, we consider a device-to-device communication system, where a multi-antenna mobile user directly communicates with nearby multiple devices, and propose a low-latency random access protocol utilizing random beams at the user.

Performance optimization for mMTC in 5G network with multiple random access schemes

open access: yes物联网学报, 2022
To optimize the support for massive machine type communication (mMTC) services with different traffic characteristics, packet-based random access (PBRA) scheme coexists with the connection-based random access (CBRA) scheme in 5G networks.Yet, given the ...

Random access DNA memory using Boolean search in an archival file storage system

open access: yesNature Materials, 2021
DNA is an ultrahigh-density storage medium that could meet exponentially growing worldwide demand for archival data storage if DNA synthesis costs declined sufficiently and if random access of files within exabyte-to-yottabyte-scale DNA data pools were ...

On the Trade-off Between Spectrum Efficiency with Dedicated Access and Short End-to-End Transmission Delays with Random Access in DVB-RCS2 [PDF]

open access: yes, 2013
This paper analyses the performance of TCP over random and dedicated access methods in the context of DVB-RCS2. Random access methods introduce a lower connection delay compared to dedicated methods.
