    Abstract: Disclosed are some examples of techniques for decentralized and scalable ranging and positioning of distributed devices. For example, an anchor user equipment (UE) can detect, from initiator user equipments (UEs), respective initiator positioning reference signal (PRS) transmissions associated with respective initiator positioning sessions. Based on the initiator PRS transmissions, one or more characteristics of PRS messaging associated with the initiator positioning sessions can be determined. When the one or more characteristics satisfies a criterion or criteria, the anchor UE can broadcast an anchor PRS transmission indicating initiation of an anchor positioning session by the anchor UE.

    Abstract: A method and apparatus for a non-geosynchronous orbit (NGSO) satellite to comply with equivalent power flux density (EPFD) limits are disclosed. The example implementations may allow a constellation of NGSO satellites to comply with EPFD limits without disabling beams transmitted from the NGSO satellites. The power level of one or more beams to be transmitted from the NGSO satellites may be dynamically adjusted according to a beam power back-off schedule. In some aspects, the beam power back-off schedule may specify beam power back-off values as a function of latitude on Earth, and may allow for maximum allowable power levels for beams transmitted from the NGSO satellites without violating any of the EPFD percentile limits.

    Abstract: A method and apparatus for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation are disclosed. In some aspects, a coverage area on Earth for a first beam transmitted from a first satellite in the NGSO satellite constellation may be determined, a cone may be projected onto a first region of the beam coverage area, a second region of the beam coverage area may be defined as including portions of the beam coverage area lying outside the first region, and a minimum arc angle for each of a plurality of points within the first region but not the second region of the beam coverage area may be determined.

    Abstract: A method and apparatus for operating one or more satellites in a non-geosynchronous orbit (NGSO) satellite constellation are disclosed. In some aspects, the satellite may allocate a first frequency band to a first beam, and may allocate a second frequency band to a second beam. Then, if the first beam is disabled, the satellite may re-map the first frequency band from the first beam to the second beam. In this manner, frequency resources initially allocated to a disabled beam may be re-mapping to another, non-disabled beam.

    Abstract: Various aspects of an approach for generating a large number of balanced weight sequences such as balanced Hamming weight preamble sequences are described herein. The approach provides for the generation of balanced weigh sequences that need to satisfy requirements such as minimal cross-correlation with delayed versions of itself and other sequences in the allowed set. The approach includes creating a set of symbol groups that include balanced properties from which a sequence may be generated by selecting therefrom.
