  • Patent number: 10736051
    Abstract: To reduce wireless interference (noise) in a network environment, a management resource communicates a notification to multiple wireless access points. The notification indicates a wireless power transmit test to be performed with respect to the primary wireless access point in a vicinity of the multiple wireless access points. In accordance with the wireless power transmit test, the primary wireless access point transmits multiple test communications at different wireless power levels from the primary wireless access point to the multiple wireless access points. The multiple wireless access points generate feedback based on their ability to receive the test communications. The feedback indicates wireless power levels at which the multiple wireless access points receive the test communications at different power levels from the primary wireless access point.

  • Patent number: 10720830
    Abstract: This specification discloses methods and systems for reducing negative undershoot during transient load response for a PWM (Pulse Width Modulation) boost power converter. In some embodiments, reduction of negative undershoot during transient load response is achieved by overriding the PWM duty cycle to a maximum duty cycle when VDDBOOST drops during load step. This maximum duty cycle (“max”) mode is triggered when VDDBOOST is within a hysteresis window. Setpoint for maximum duty cycle is versus DCDC converter output and input voltage. In some embodiments, a lookup table is implemented for determining the setpoint for maximum duty cycle.

  • Patent number: 10715294
    Abstract: In a wireless communication system, a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes results in failure of data recovery.

  • Patent number: 10674456
    Abstract: Multiple downlink (DL) and uplink (UL) carriers can enhance wireless communication between nodes and user equipment (UE). Among the carriers, it is beneficial to have some special, by configuration designated carriers to provide synchronization, system information, paging, data and control for multi-carrier enabled UEs. Thereby, overhead system information can be reduced. For instance, synchronization and paging for a certain cell are not provided on all carriers. A carrier can provide backward compatibility for single carrier UEs for access, synchronization, broadcast, and new control region within the data region of the legacy terminals. Coordination between nodes for selecting anchor carriers that mitigate interference and for transmit power control for non-anchor carriers provide further network performance advantages.
