NOMAbased 802.11n for Broadcasting Multimedia Content in Factory Automation Environments Industry 4.0 requirements in reliability and latency are still a challenge for wireless communications systems due to the factory critical propagation scenarios. Additionally, further improvements are required in order to enhance the performance of wireless technologies in terms of reliability and latency before presenting them as a valid alternative to the wired technologies. These challenges are added to the increasing needs of bitrate to deliver multimedia content in Factory Automation (FA) environments. This paper proposes several use cases, which include video transmission and a specific technical solution based on a combination of NOMA and the IEEE 802.11n standard. The PHYMAC proposal is evaluated on a reference scenario based on the deployment of the typical industrial applications. Results show that NOMAbased systems offer a very promising reliability gain in comparison to classical TDMAbased systems. In fact, for the most unbalanced service combinations a PER (Packet Error Rate) improvement of more than one order of magnitude can be obtained.

NOMA based 5G NR for PTM Communications Recent advances in broadband communications have led to the first standardization phase of 5G (Relxe2x80x99 15). Several works present this novel standard as the main solution in order to cover all the new requirements that have arisen in the multimedia delivery industry. However, the latest 5G release does not include the option of transmitting traditional broadcast services. That is why, in this paper, NonOrthogonal Multiple Access (NOMA) is presented as a promising candidate in order to boost the implementation of the broadcastmulticast communications within the 5G NR standard. Therefore, a 5G New Radio (NR) fully compliant simulation tool has been developed and NOMA multiplexing schemes have been added, introducing as few modifications as possible. The simulation platform and proposed techniques have been tested within two different use cases. Results present a better overall reliability performance of the communications by using NOMA. In fact, both services performance is improved when compared to traditional TDMA schemes, with a maximum gain around 4 dB.
