    Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile GNSS device to compensate for arm swing. An example of an method for compensating for arm swing according to the disclosure includes determining an arm swing signal, such that the arm swing signal is approximately sinusoidal with a period of approximately T seconds, determining a position signal measurement period, receiving a plurality of positioning signals at intervals corresponding to the position signal measurement period, and determining current position information based on the plurality of positioning signals.

    Abstract: Mobile devices often use orthogonal frequency division multiplexing (OFDM) to calculate position information of mobile devices within the network. However, physical distance between the mobile device and a signal source for positioning and other environmental factors can influence the signal strength of received signals. Received signals at the mobile device that are stronger may drown out the weaker signals, particularly when two signal sources occupy the same symbol. In traditional OFDM, a signal source transmits the same symbol for each positioning occasion, so a weaker signal may never be detected over a stronger signal, reducing the accuracy of the positioning calculations. Described herein are systems and methods for using a pattern to vary the designated symbol for each signal source in a wireless network so that a weaker signal from a signal source may be detected on at least some of the positioning occasions.

    Abstract: Methods, apparatuses, and computer-readable media are described. In one example, a method, on a base station, for providing position measurements signals in a wireless communication network, comprises: determining a plurality of subcarriers for downlink transmission, wherein the plurality of subcarriers for downlink transmission comprise all subcarriers indicated in a resource block of a scheduled time of transmission within a scheduled transmission occasion, wherein the resource block comprises a plurality of symbol periods, wherein each symbol period of the plurality of symbol periods is for transmission of a symbol using one or more subcarriers of the plurality of subcarriers; and transmitting at the scheduled time of transmission, and using each subcarrier of the plurality of subcarriers, a wireless position measurement signal at the scheduled transmission occasion, the wireless position measurement signal being part of a sequence of wireless signals representing a position measurement signal bitstream.

    Abstract: Techniques for managing power consumption of a Global Navigation Satellite System (GNSS) receiver of a mobile device are provided. These techniques include a method that includes deriving a GNSS search window for the GNSS receiver based on a position uncertainty (PUNC) and a time uncertainty (TUNC), selecting a GNSS search mode based on the GNSS search window and resources available for searching for signals from GNSS satellite vehicles (SVs), wherein an estimated power consumption associated with execution of a GNSS search associated with the GNSS search mode does not exceed a power consumption limit specified for the GNSS receiver conducting the GNSS search using the GNSS search mode, and estimating a position of the mobile device.
