  • Patent number: 11632737
    Abstract: A wireless network including user equipment (UE) and base stations is configured to perform position determination with low latency and high availability within the Time-Sensitive Networking (TSN) framework. For example, the UE may be integrated as a sensor in a motion control system or similar applications. The UE and base stations are synchronized with the TSN clock, and are configured to perform positioning measurements at a specific time point within the TSN framework. The time point, for example, may be a global sampling point, at which all sensor nodes in the TSN framework perform position measurements. A location server may be provided with the positioning measurements or a position estimate from the UE and provide the position estimate to an external client, such as a motion controller in a motion control system.

  • Patent number: 11632775
    Abstract: This disclosure provides systems, methods, and devices for wireless communication that support managing allocation of configured grant (CG) resources for uplink transmissions using a polynomial over Galois field in a wireless communication system. In particular, a user equipment (UE) may be configured (e.g., by a base station) to determine a resource to access, from a resource pool configured for each CG occasion of a CG configuration, based on a polynomial over Galois field configured for the UE. The polynomial over Galois field may include a parameter p, and the UE may be configured with a mapping that maps the absolute time (e.g., a slot index or a symbol index) of a GC occasion to an index between 0 and p?1 that is used as input to the polynomial The result of the polynomial is used to determine the resource to access by the UE at the CG occasion.

  • Publication number: 20230101624
    Abstract: Positioning of one or more user equipments (UEs) is performed using broadcast common sounding reference signals (SRS) resources for positioning. The common SRS that is broadcast by a UE is received and measured by one or more base stations and one or more other UEs. The other UEs may have known positions and may server as anchor nodes for positioning. The other UEs may have known positions and may serve as a positioning (anchor) node or may have unknown positions and may be jointly positioned with the target UE. During joint positioning, each of the other UEs may similarly broadcast a common set of SRS that is received and measured by the base stations and other UEs for positioning. An angular measurement of the SRS broadcast by one or more UEs may be measured and used to resolve mirror symmetry in positioning solutions.
