Patent number: 12323365Abstract: In an example arrangement, a base station (16) serving a wireless device (14) controls the activation time for transmission by the wireless device (14) of aperiodic or semipersistent Sounding Reference Signals (SRS), but accounts for an activation-time recommendation made by a location server (20) with which the serving base station (16) provides its timing information. The arrangement allows the location server (20), which has a view of the overall timeline, to recommend an activation time while still leaving the serving base station (16) in control of the activation time, which the serving base station (16) shares with the location server (20). In turn, the location server (20) uses the activation time to configure neighboring base stations (16), for example, for coordinated reception of the SRS, for positioning the device (14) via Uplink Observed Time Difference of Arrival (UTDOA) determinations.Type: GrantFiled: May 13, 2020Date of Patent: June 3, 2025Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Ritesh Shreevastav, Florent Munier, Iana Siomina

Patent number: 12323867Abstract: A wireless device (10) sets up a first radio connection to a first access node (101-1, 101-2) of the wireless communication network. The first radio connection is based on a first radio technology. The wireless device (10) measures first signal strengths of reference signals from access nodes (101-1, 101-2) operating on the basis of the first radio technology. Further, the wireless device (10) measures second signal strengths of reference signals from one or more second access nodes (101-3, 101-4) which operate on the basis of a second radio technology. In response to the measured second signal strengths satisfying a first set of conditions, the wireless device (10) sends a first type of measurement report to the first access node. In response to expiry of a time interval without having sent the first type of measurement report, the wireless device (10) stops the measuring of the second signal strengths.Type: GrantFiled: June 30, 2020Date of Patent: June 3, 2025Assignee: Telefonaktiebolaget LM Ericsson (Publ)Inventors: Varun Prabhu Joshi, Miruna-Teodora Wiszniewski, Markus Schneider
