  • Patent number: 10715304
    Abstract: The present invention discloses a modulation method and a modulation apparatus applicable to an OvXDM system, and an OvXDM system. On the one hand, an initial envelope waveform is virtually cut off, and a modulation-domain shift interval is calculated by using a virtual cutoff width of the initial envelope waveform, such that a symbol width obtained after modulation becomes smaller, and a transmission rate is improved; on the other hand, because the initial envelope waveform is virtually cut off but not really cut off, shifting and superimposition are still performed on an initial envelope waveform with tailing, such that the waveform still retains a good performance, such as a relatively narrow width and relatively fast side lobe attenuation, in a corresponding domain. Therefore, in the present invention, the good performance of the waveform is retained in the corresponding domain while the transmission rate is increased.

  • Patent number: 10708190
    Abstract: A method of control Maximum Transmission Unit (MTU) reporting and discovery using AT commands is proposed. In communications networks, the MTU of a communication protocol of a layer is the size (in bytes or octets) of the largest protocol data unit that the layer can pass onwards. In an IP network, IP packets may be fragmented if the supported MTU size is smaller than the packet length. In accordance with one novel aspect, the packet data protocol (PDP) context of a packet data network (PDN) connection comprises MTU information. By introducing MTU information to the PDP contexts, TE can use AT commands to query MTU parameters from the network and thereby avoid fragmentation. TE can also use AT command to set MTU parameters and thereby control MTU discovery.

  • Patent number: 10699500
    Abstract: A method for operating an access control comprises creating a plurality of wake-up schedules for a wireless transceiver. Each of the plurality of wake-up schedules may be configured to control how frequently the wireless transceiver wakes up to transmit or receive information. Each of the plurality of wake-up schedules for the wireless transceiver may be different from another one or the plurality of wake-up schedules for the wireless transceiver. The method may further comprise automatically switching between the plurality of wake-up schedules for the wireless transceiver such that a duration of time between wake-ups for the wireless transceiver radio is shorter during some predefined times and longer during other predefined times. The duration of time between wake-ups for the wireless transceiver may be configurable by an administrative user via an interface.

  • Patent number: 10698782
    Abstract: A link downgrade detection system includes an interface that is coupled to an endpoint device. The endpoint device is configured to provide an endpoint link that includes a first link capability at a maximum first link capability level and a second link capability at a maximum second link capability level. The endpoint device stores a working first link capability level and a working second link capability level in a first memory device included on the endpoint device. A BIOS coupled to the chassis interface enumerates the endpoint device, determines an actual first link capability level and an actual second link capability level, and retrieves the working link capability levels. The BIOS then determines, based on the working link capability levels and the actual link capability levels that the endpoint link is downgraded, and in response provides a notification that the endpoint link of the endpoint device is downgraded.

  • Patent number: 10701546
    Abstract: In one embodiment, a service maintains a mobility path graph that represents roaming transitions between wireless access points in a network by client devices in the network. The service associates metrics regarding roaming delays to mobility paths in the mobility path graph. The service identifies a roaming boundary change that is predicted to reduce roaming delays between two or more wireless access points in the network, in part by assessing the metrics regarding roaming delays associated with the mobility paths in the mobility path graph. The service provides an indication of the identified roaming boundary change to a user interface.

  • Patent number: 10701673
    Abstract: The present invention relates to reporting the channel state information in a communication system. The channel state information is reported from the user terminal to a base station. Accordingly, the user terminal determines a first channel state information value from a first set of values (levels) and a second channel state information value from another set of values, preferably a larger set of values. Then a difference or other relative measure is calculated between the first and the second channel state information value and transmitted to the base station.

  • Patent number: 10694495
    Abstract: Methods and apparatus for efficient paging in a communications system using unlicensed spectrum are described. A base station, which uses unlicensed spectrum, receives a paging request message from a network node and performs paging operations attempting to page the UE. The paging attempt may fail due to the base station being unable to transmit a paging signal to the UE because the unlicensed spectrum is currently unavailable or because the UE did not respond to a transmitted page. The base station generates and transmits a paging failure response message including a failure cause code indicating the reason that the paging attempt failed. The network node receives the paging failure response message, recovers the failure cause code, and implements a paging escalation strategy as a function of the recovered failure cause code.
