  • Patent number: 10673485
    Abstract: A method and a receiving node for determining Time Of Arrival (TOA) for a radio signal received from a transmitting node in a wireless network. The receiving node detects the received radio signal by cross-correlating the received radio signal with a predefined reference signal transmitted by the transmitting node, to obtain a Cross-Correlated Function (CCF). The receiving node then estimates a set of candidate TOAs for respective signal components of the cross-correlated signal, and determines a final TOA for the received radio signal based on the set of candidate TOAs.

  • Patent number: 10673441
    Abstract: A frequency generation solution controls an oscillator amplitude using two feedback paths to generate high frequency signals with lower power consumption and lower noise. A first feedback path provides continuous control of the oscillator amplitude responsive to an amplitude detected at the oscillator output. A second feedback path provides discrete control of the amplitude regulating parameter(s) of the oscillator responsive to the detected oscillator amplitude. Because the second feedback path enables the adjustment of the amplitude regulating parameter(s), the second feedback path enables an amplifier in the first feedback path to operate at a reduced gain, and thus also at a reduced power and a reduced noise, without jeopardizing the performance of the oscillator.

  • Patent number: 10674329
    Abstract: Methods and apparatuses maintain user-plane session status information of user equipment in an edge cloud. Upon determining that a handover of UE at a network edge has occurred, a status-information-acquisition mechanism is added to a handover signaling chain. The status-information-acquisition mechanism triggers providing UP session status information of the UE to a target gateway, which intermediates traffic between the target base station and a network device outside the edge cloud. The UP session status information of the UE is then used by the target gateway to determine UE-related data to be reported to the network device for execution of a function such as legal interception or charging.
