Patent
Synchronizing method and apparatus using error detection of sequence numbers to avoid synchronizing failure
TL;DR: In this article, the authors present an approach for transmissions and retransmissions of packet data, particularly ciphered data, in a communications system, which relates to radio link transmissions and avoidance of deciphering failures in a cellular mobile radio system, particularly a Universal Mobile Telecommunications System, UMTS or WCDMA system.
Patent
Communications system and method for transmitting data between a terminal and network resources
TL;DR: In this paper, the authors present a communication system consisting of a terminal, and network resources, where the terminal is operable to transmit substantially simultaneously a data portion and a data transfer request for that data portion to the network resources.

Wireless Protection of Power Grids over a 5G Network
Gustav Wikström,Johan Torsner,Jonas Kronander,Osama Al-Saadeh,Fedor Chernogorov,Gargi Bag,Jonas Neander,Krister Landernäs,Petri Hovila +8 more
TL;DR: Using a 5G macro network, this work shows that line differential protection can be handled with wireless ultra-reliable low latency communication and can be delivered on the same band handling Mobile Broadband traffic.
Patent
Radio resource management in wireless communication systems
TL;DR: In this article, the authors proposed a radio resource management in wireless communication systems, which operate based on directive beams for serving one or more wireless user devices, by processing image information obtained from one or multiple image sensors to predict a change in radio propagation characteristics between a network node and a user device.
Patent
Method, arrangement, node and mobile unit for improved transmission between two units of a telecommunication system
Stefan Parkvall,Johan Torsner +1 more
TL;DR: In this article, a mechanism for improved data transmission between units in a telecommunication network, where at least one of the units utilizes multiple transport channels for transmitting data, is proposed, where acknowledgeable data transmission is started over a first transport channel if no other on-going acknowledgeability data transmission on a second transport channel starts or ends within a pre-defined or assigned transmission period for the first channel.
