  • Patent number: 11689477
    Abstract: A method and device are provided for synchronizing data transmission of multicasting/broadcasting services (MBS) by a plurality of Base Stations. Meanwhile, each of the Base Stations receives the MBS data to be transmitted and determines whether any of the MBS data has not been properly received. If so, the respective Base Station may initiate a process to recover the missing MBS data and/or to obtain information regarding the missing data to determine the duration of the time period that would have been required for transmitting the missing MBS. If the missing data has not been timely recovered, the respective Base Station determines a starting point and the duration of a silence period based on the information obtained, and refrains from transmitting signals along a communication channel allocated for transmission of MBS data, during that silence period.

  • Publication number: 20230077069
    Abstract: A system and method for timing synchronization of global navigation satellite system (GNSS) receivers is presented. An end point equipment (EPE) of a plurality of EPEs is matched to at least one control station at a predetermined distance, which are in a user satellite network. Relative positions are determined for each matched EPE and the at least one control station based on differencing of raw measurements and a plurality of relative positions is collected of the determined relative position of each match. An absolute clock offset is estimated based on clock information of the at least one control station and the plurality of relative positions. The absolute clock offset is used to cause a time synchronization in a first EPE of a plurality of EPEs.

  • Patent number: 11169242
    Abstract: A system and method for locating a mobile device relative to a vehicle using mechanical waves and modulation techniques. A high frequency carrier wave that is generally inaudible to humans is modulated with a low frequency baseband signal that provides for accurate localization in order to generate a modulated signal. The modulated signal is a mechanical or pressure wave, as opposed to an electromagnetic (EM) wave, that is transmitted by one or more speaker(s) and is received by one or more microphone(s). In one example, the modulated signal is transmitted from a speaker on the mobile device (e.g., a smart phone) to a number of microphones mounted on the vehicle at specific distances apart, so as to establish multiple localization paths whose differences in phase can be used to determine the location of the mobile device, relative to the vehicle.
