Access Delay Constrained Activity Detection in Massive Random Access [PDF]
2021 IEEE 22nd International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2021 In 5G and future generation wireless systems, massive IoT networks with bursty traffic are expected to co-exist with cellular systems to serve several latency-critical applications. Thus, it is important for the access points to identify the active devices promptly with minimal resource consumption to enable massive machine-type communication without ...

Massive Unsourced Random Access for Massive MIMO Correlated Channels [PDF]
GLOBECOM 2020 - 2020 IEEE Global Communications Conference, 2020 This paper investigates the massive random access for a huge amount of user devices served by a base station (BS) equipped with a massive number of antennas. We consider a grant-free unsourced random access (U-RA) scheme where all users possess the same codebook and the BS aims at declaring a list of transmitted codewords and recovering the messages ...

Improving Massive Access to IoT Gateways
Performance Evaluation, 2022 IoT networks handle incoming packets from large numbers of IoT Devices (IoTDs) to IoT Gateways. This can lead to the IoT Massive Access Problem that causes bu er overflow, large end-to-end delays and missed deadlines. This paper analyzes a novel tra c shaping method named the Quasi-Deterministic Tra c Policy (QDTP) that mitigates this problem by ...

Random Access Protocols for Massive MIMO [PDF]
IEEE Communications Magazine, 2017 5G wireless networks are expected to support new services with stringent requirements on data rates, latency and reliability. One novel feature is the ability to serve a dense crowd of devices, calling for radically new ways of accessing the network. This is the case in machine-type communications, but also in urban environments and hotspots.
