  • Publication number: 20240098561
    Abstract: Systems and methods are described for implementing a distributed unit in an open radio access network that manages its workload to reduce the risk of missing a radio unit timeslot. A distributed unit may receive data from a centralized unit and transmit the data to a radio unit, which may transmit the data to user devices during fixed timeslots. The distributed unit must therefore transmit data to the radio unit for delivery during each timeslot to prevent “dead air” and potential connectivity issues. The distributed unit thus monitors its workload, determines whether its risk of missing a window for transmitting data to the radio unit satisfies a criterion, and then if necessary reduces its workload until the criterion is no longer satisfied. The distributed unit may communicate with an access and mobility management function or other network component to facilitate workload management.

  • Publication number: 20240098666
    Abstract: Systems and methods are described for implementing a distributed unit in a radio access network that synchronizes its clock with a radio unit. A distributed unit may be deployed in a location where it cannot receive timing information from a satellite or may lack the equipment to obtain and process satellite signals. The clock of the distributed unit may thus drift relative to the clocks of the radio units, which may cause the distributed unit to mistime its transmissions of data to radio units for delivery to user devices. The distributed unit may prevent clock drift by obtaining timing information from the radio units, determining an amount of clock drift that is occurring, and applying a correction factor to keep the distributed unit clock synchronized with the radio unit clock. The distributed unit may determine how often to synchronize based on the severity and variability of the clock drift.

  • Patent number: 10812991
    Abstract: Mitigating interference between transmitters and receivers associated with satellite systems and mobile wireless systems may include receiving information associated with the transmitter, determining a distance between the transmitter and the receiver based on the received information, determining if the distance is less than a distance threshold, estimating an interference level based on determining that the distance is less than the distance threshold, determining if the estimated interference level exceeds an interference threshold, computing an angle between an antenna of the transmitter and the receiver based upon determining that the estimated interference exceeds the interference threshold, and directing, when receiving a signal, a main lobe of a receive antenna pattern of the receiver towards the signal, and forming nulls in the receive antenna pattern in a direction of at least one side lobe of a transmit pattern of the transmitter.

  • Patent number: 9820154
    Abstract: Methods, systems, and devices are described for making scaling adjustments with respect to a fractional subsystem in a wireless communications system. To handle the effects of scaling associated with fractional bandwidth systems, different adjustments may be made to maintain certain quality of service (QoS) requirements, for example. Scaling adjustments may include identifying a scaling factor for the fractional subsystem and a parameter and/or a timer associated with the fractional subsystem. An adjustment associated with the parameter and/or timer may be determined based on the scaling factor. The adjustment may be applied with respect to the parameter and/or timer for at least a portion of the fractional subsystem or another portion of the wireless communications system.

  • Patent number: 9699682
    Abstract: An apparatus for capturing a signal of interest, e.g., PSS and/or SSS, captures data transmitted by a first RAT by obtaining access to a receive chain for a second RAT during a measurement gap for the first RAT. The signal of interest transmitted by the first RAT is captured during the measurement gap using the receive chain for the second RAT. Access to a receive chain for the second RAT may be obtained in any one of several ways. For example, access may be obtained by 1) requesting receive chain access for the second RAT for LTE measurements through a virtual flow, 2) entering into a power save mode, 3) tuning to a non-operating channel, 4) setting network allocation vector (NAV) at or above a threshold value, or 5) entering a measurement mode during which the receive chain for the second RAT is prevented from performing WLAN operations.
