  • Patent number: 10278133
    Abstract: A system and method for controlling uplink power to combat rain fade in satellite communication systems. First communication signals transmitted from a satellite to a satellite operations center are monitored at a gateway. A downlink attenuation level is determined for the first communication signals, and compared to an ideal attenuation level. if the downlink attenuation level exceeds the ideal attenuation level, then a corresponding uplink attenuation level is determined for a second frequency used to transmit second communication signals to the satellite, and converted to a power control command for adjusting an amplifier gain. The second communication signals are transmitted to the satellite at either a compensated power level or a normal power level, depending on whether the downlink attenuation level exceeds the ideal attenuation level.

  • Patent number: 10231188
    Abstract: Controlling the uplink transmission power includes dynamically activating and deactivating a high-power transmission mode of the wireless devices in response to changes in a network topology, such as presence or absence of different types of access nodes, and signal level measurements of reference signals transmitted from said different types of access nodes. Such dynamic control of the uplink transmission power in real time minimizes interference that may be caused to uplink transmissions of other wireless devices in the network, and mitigates unnecessary power consumption for wireless devices capable of utilizing the high-power mode.

  • Patent number: 10154464
    Abstract: There is provided a wireless communication apparatus and wireless communication method, which can perform information transfer, while suppressing interference to other terminal stations, and preventing a reduction of a transmission opportunity of other terminal stations. By causing the transmission power to be reduced, at the time when a traffic amount to be transmitted and received by itself increases, a terminal station which performs wireless access based on CSMA on a mesh network can suppress interference to other surrounding terminal stations, and can prevent a reduction of a transmission opportunity of other terminal stations. By measuring the number of and sizes of packets to be transmitted and received, it is possible for a terminal station to comprehend the traffic amount to be transmitted and received by itself, and perform a control of the transmission power by this.

The positional tracking system tracks position of the HMD and generates positional information describing the tracked position of the HMD. The transceiver communicates with a console via a wireless channel, in accordance with communication instructions, the communication instructions causing the transceiver to communicate over one directional beam of a plurality of directional beams. The beam controller determines a change in the positional information. Based on the change to the positional information, the beam controller determines a directional beam of the plurality of directional beams. The beam controller further generates the communication instructions identifying the determined directional beam, and provides the communication instructions to the transceiver.
