Patent number: 10834694Abstract: Exemplary embodiments include methods for adjusting transmission timing of a wireless communication device (UE) operating in a network including first and second base stations (BS). The methods include determining a first allowable timing adjustment range corresponding to an uplink (UL) connection between the UE and the first BS, and determining a second allowable timing adjustment range corresponding to a supplementary uplink (SUL) connection between the UE and the second BS. The SUL connection is not associated with a DL connection between the UE and the second BS. The methods include determining if a single timing advance (TA) value can be used to adjust the UE's transmission timing to satisfy both the first and second ranges, and performing a corrective action if it is determined that a single TA value cannot be used. Embodiments also include first and second BS, and UEs, configured to perform the exemplary methods.Type: GrantFiled: March 26, 2019Date of Patent: November 10, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Magnus Sandgren, Robert Baldemair, Torgny Palenius

Publication number: 20200314782Abstract: In one aspect, a network access node requests, via a service request, a synchronization service from a network node, receives synchronization source information corresponding to the synchronization service and uses the synchronization source information to detect and measure signals from a synchronization source node. The network access node stores signal identifiers corresponding to one or more of the measured signals as neighbor information and subsequently performs signal measurements on signals from the synchronization source node, based on the stored signal identifiers, and uses the signal measurements to perform a mobility operation.Type: ApplicationFiled: March 31, 2017Publication date: October 1, 2020Inventors: Stefano RUFFINI, Angelo CENTONZA, Magnus SANDGREN

Publication number: 20200259896Abstract: Techniques for enhancing performance in Industrial Internet-of-Things (IIoT) scenarios, including techniques for time-sensitive networking (TSN) and 5G wireless network integration. An example method, performed by a wireless device, comprises receiving system information (SI) from a radio base station (RBS) of a radio access network (RAN), the SI being indicative of support for TSN through the RBS, and establishing at least one TSN stream with an external data network, through the RBS. The example method further includes receiving a first timing signal from the wireless communications network, via the RBS, receiving a second timing signal from the external TSN data network to which the wireless device is connected, comparing the first timing signal to the second timing signal to determine an offset, and transmitting the offset to the wireless communications network.Type: ApplicationFiled: February 13, 2019Publication date: August 13, 2020Inventors: Joachim Sachs, Abdulrahman Alabbasi, Mattias Andersson, Niklas Andgart, Ola Angelsmark, José Araújo, Muhammad Ikram Ashraf, Kumar Balachandran, Robert Baldemair, Rodrigo Berg, Yufei Blankenship, Fedor Chernogorov, John Walter Diachina, Torsten Dudda, Henrik Enbuske, Sorour Falahati, János Farkas, Jonas Fröberg Olsson, Majid Gerami, Harald Gustafsson, Kimmo Hiltunen, Andreas Höglund, Torgny Holmberg, Zsolt Kenesi, András Kern, Kittipong Kittichokechai, Anna Larmo, Johan Lundsjö, György Miklós, Hubertus Munz, Gabor Nemeth, Johannes Nygren, Johan Olsson, Alexandros Palaios, Dhruvin Patel, Joakim Persson, Per Persson, Jose Luis Pradas, Sándor Rácz, Pradeepa Ramachandra, Norbert Reider, Dinand Roeland, Stefano Ruffini, Patrik Salmela, Sara Sandberg, Magnus Sandgren, Paul Schliwa-Bertling, Alexey Shapin, Nianshan Shi, Bikramjit Singh, Per Skarin, Bernard Smeets, Ying Sun, Dennis Sundman, Fredrik Svensson, Malgorzata Svensson, Geza Szabo, Wolfgang Tonutti, Balázs Varga, Mårten Wahlström, Kun Wang, Yi-Pin Eric Wang, Osman Nuri Can Yilmaz, Zhenhua Zou, Miguel Lopez

Publication number: 20190357157Abstract: In a radio communications network using a TDD structure to communicate with UE terminals, a radio network node applies such a TDD structure that at least one guard period is included in each slot between a downlink transmission period containing at least one downlink symbol and an uplink reception period containing at least one uplink symbol. Each guard period represents an interval during which the radio network node does not transmit any data. The radio network node allocates the guard periods dynamically by checking whether at synchronization degradation criterion is fulfilled; and if at least one of the at least one synchronization degradation criterion is fulfilled, the radio network node increases the guard period to have an extended duration relative to a previous duration.Type: ApplicationFiled: January 16, 2017Publication date: November 21, 2019Inventors: Magnus SANDGREN, Robert BALDEMAIR, Anders HÖGLUND, Mårten WAHLSTRÖM
