Patent number: 11812398Abstract: A group of radio network nodes (14) performs automatic synchronization source selection using Radio-interface Based Synchronization, based on the exchange of clock-attribute information between respective nodes (14) via inter-node connections. Access to the clock-attribute information for other nodes (14) in the same domain or subdomain allows a given node (14) to select the best or most preferred synchronization source for use in synchronizing its own clock (44), based on a combined or joint evaluation of parameters or metrics that include the reception quality of OTA signals from respective ones of the candidate nodes (14) and the corresponding clock-attribute information. Further parameters or metrics may be evaluated in the selection, such as neighbor-relation considerations. The combined use of OTA synchronization signaling and clock-attribute information exchanges, e.g.Type: GrantFiled: February 28, 2019Date of Patent: November 7, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Stefano Ruffini, Garry Irvine, Ohan Khodaverdian, Magnus Sandgren, Mårten Wahlström

Patent number: 11785568Abstract: In some embodiments, a network node (e.g., a base station) collects information pertaining to components that form a Maximum Received Timing Difference (MRTD). For instance, the network node determines TAE. The network node then evaluates, for a particular UE, whether a certain MRTD requirement (MRTDR) for a specific coordinated service (CS) can be fulfilled. If the requirement can be met, then the network node may initiate the specific CS for the UE (or continue providing the CS), and if the requirement cannot be met, then the network node may stop or modify the CS for the UE.Type: GrantFiled: November 19, 2018Date of Patent: October 10, 2023Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Magnus Sandgren, Garry Irvine, Walter Müller, Christer Östberg, Torgny Palenius

Publication number: 20200142025Abstract: A method, user equipment (UE) and location server for estimating position of a UE based on observed angles of arrival. According to one embodiment, angles of arrival of signals from a plurality of base stations are received by a UE are observed by scanning for position reference signals (PRS) by adjusting a phase difference between antennas to cause a null of a beam of the UE to be incremented through an angular sector. For each of a plurality of base stations, an angle of arrival at which the null is steered when a PRS is suppressed by the null and a reference signal time difference, RSTD, are determined. Each angle of arrival and corresponding RSTD is transmitted to a location server which estimates UE position based on the observed angles of arrival. Further, the location server may instruct the UE to suppress a non-line-of-sight PRS signal.Type: ApplicationFiled: January 8, 2020Publication date: May 7, 2020Inventors: Garry IRVINE, Peter DEANE

Patent number: 10006984Abstract: Systems and methods for determining a location of a wireless device are disclosed. In one embodiment, a method of operation of a central processing node for a shared cell of a cellular communications network includes obtaining signal strength measurements for a signal received from a wireless device at multiple Reception/Transmission (R/T) points in the shared cell. The signal strength measurements are simultaneous signal strength measurements made on signal discrimination space resources in an uplink of the shared cell. Further, the signal discrimination space resources are matched to capabilities of power meters utilized to generate the signal strength measurements. The method further includes identifying one or more of the R/T points having the best signal strength measurements and estimating a location of the wireless device based on known locations of the identified R/T point(s).Type: GrantFiled: June 18, 2014Date of Patent: June 26, 2018Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Leonard Lightstone, Garry Irvine, François Cardinal, Peter Pääkkönen, Adrien Comeau
