Patent number: 11849371Abstract: During a positioning session, a user equipment (UE) is provided with an early uplink grant to respond to a request for location service information from a location server. The location service information, for example, may be a request for positioning capabilities, a request for positioning measurements or a position estimate, and may be a request for a single, periodic or triggered location information. The early uplink grant may be requested by the UE prior to needing the uplink grant, e.g., before the positioning measurements have been completed. The location server may instigate the early uplink grant, e.g., at or near the same time that the location server sends the request for information to the UE. The early uplink grant may be used, e.g., during high priority or emergency related positioning sessions, in order to reduce delay in the UE providing a response to the request for location information.Type: GrantFiled: August 17, 2021Date of Patent: December 19, 2023Assignee: QUALCOMM IncorporatedInventors: Bapineedu Chowdary Gummadi, Stephen William Edge, Hem Agnihotri, Amit Priyadarshi

Patent number: 11722912Abstract: When an integrated access backhaul (IAB) node connected to a user equipment (UE) detects a radio link failure in a communication with an IAB donor, the IAB node may perform various features to cause the UE perform one or more features accordingly without explicitly indicating the radio link failure to the UE. The IAB node may detecting a radio link failure in a communication between the IAB node and an IAB donor, and determine whether the IAB node has recovered from the radio link failure. The IAB node may refrain from broadcasting one or more synchronization signal blocks (SSBs) to one or more UEs including a UE connected to the IAB node in response to determining that the IAB node has not recovered from the radio link failure.Type: GrantFiled: January 25, 2021Date of Patent: August 8, 2023Assignee: QUALCOMM IncorporatedInventors: Bapineedu Chowdary Gummadi, Naeem Akl, Hem Agnihotri, Karl Georg Hampel, Navid Abedini

Patent number: 11716137Abstract: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.Type: GrantFiled: December 10, 2020Date of Patent: August 1, 2023Assignee: QUALCOMM IncorporatedInventors: Andrei Dragos Radulescu, Hem Agnihotri, Stephen William Edge, Sven Fischer, Bapineedu Chowdary Gummadi, Venkata A Naidu Babbadi

Patent number: 11619702Abstract: The angle of departure (AOD) of directed beams, e.g., beamformed beams, transmitted by one or more base stations, such as a gNB, and the angle of arrival (AOA) of the directed beams received by a UE may be used to improve positioning accuracy by identifying Line Of Sight (LOS) beams and multi-path beams. The differential AOA (DAOA) of a directed beam pair may compared to the differential AOD (DAOD) of the directed beam pair. Matching DAOA and DAOD may be used as an indication that the directed beams in the beam pair are LOS with the UE, whereas a mis-match indicates one or both of the directed beams are multi-path. The location of the UE may be estimated using the measurement information, e.g., AOA, RTT, RSTD, etc., obtained from LOS directed beams.Type: GrantFiled: August 13, 2020Date of Patent: April 4, 2023Assignee: QUALCOMM IncorporatedInventors: Bapineedu Chowdary Gummadi, Stephen William Edge, Hem Agnihotri

Patent number: 11483793Abstract: Disclosed are techniques for determining a location of a user equipment (UE) communicating over a shared communication medium in unlicensed spectrum. In an aspect, the UE measures a positioning reference signal (PRS) from a first evolved NodeB (eNB) for a first secondary cell (Scell) and a second PRS from a second eNB for a second Scell. The UE reports the first and second PRS measurements and the first and second PRS measurement times to a location server. In an aspect, the first and second PRS are configured according to a common PRS configuration. The location server also receives transmission times of the PRS signals from the first and second eNBs. Using the measurement and transmission times, the location server can associate the first PRS measurement to the first eNB and the second PRS measurement to the second eNB, thereby assisting the location server to obtain a location for the UE.Type: GrantFiled: April 23, 2018Date of Patent: October 25, 2022Assignee: QUALCOMM IncorporatedInventors: Hem Agnihotri, Stephen William Edge, Bapineedu Chowdary Gummadi

Publication number: 20210352610Abstract: Techniques are provided for transmitting Positioning Reference Signals (PRSs) in cells supporting two different Radio Access Technologies (RATs), where the two RATs (e.g. 4G LTE and 5G NR) employ dynamic spectrum sharing. To avoid interference between the PRSs and between the two RATs, the PRSs may be time aligned to the same set of PRS positioning occasions, and may be assigned orthogonal characteristics such as different muting patterns, orthogonal code sequences, different frequency shifts or different frequency hopping. UEs supporting both RATs may be enabled to measure PRSs for both RATs. UEs supporting only one RAT (e.g. 4G LTE) may be enabled to measure PRSs for just this RAT. A location server such as an LMF, E-SMLC or SLP may provide assistance data to UEs, and request measurements from UEs, for PRSs in one or both RATs.Type: ApplicationFiled: May 18, 2021Publication date: November 11, 2021Inventors: Bapineedu Chowdary GUMMADI, Stephen William EDGE, Hem AGNIHOTRI
