    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: 9014618
    Abstract: A cellular telecommunications network base station repeater for a mobile terminal in a network having a power control function causes, during an active communication session, mobile terminal uplink transmit power to decrease in response to an increase in signal strength of the received uplink signal. The gain of the repeater is increased in response to an increase in the uplink signal received at the repeater above a threshold, and subsequently decreasing the gain until the measured power in the received uplink signal exceeds the threshold. Due to the power control function, increasing the gain causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to decrease. Decreasing the gain causes the transmit power, and hence the received uplink signal, to increase. The threshold not being exceeded is indicative of the communication no longer being active, and the repeater will eventually deactivate.

  • Patent number: 9007888
    Abstract: Methods and apparatuses are provided for uplink MIMO transmissions in a wireless communication system. In some particular aspects, scheduling of the uplink MIMO transmissions may make a determination between single stream, rank=1 transmissions and dual stream, rank=2 transmissions based on various factors. Further, when switching between single and dual stream transmissions in the presence of HARQ retransmissions of failed packets, the scheduling function may determine to transmit the HARQ retransmissions on a single stream transmission or to transmit the HARQ retransmissions on one stream while transmitting new packets on the other stream.

  • Patent number: 8989796
    Abstract: A radio communication system including a relaying apparatus and a base station, at an installment of a new base station, a parameter is autonomously adjusts a parameter to maintain a communication of the relaying apparatus. The new base station transmits a radio signal while increasing a transmission power, and the relaying apparatus, upon detecting the radio signal, transmits a signal indicating detection of the signal to an existing base station. The existing base station, upon receiving the signal indicating the detection, reduces an transmission power thereof to a minimum power to maintain a communication with a relaying apparatus and adjusts the parameter to set the transmission power to the minimum transmission power. The new base station, based on the transmission power at a time when the relaying apparatus has detected the radio signal, sets the parameter of the transmission power.

  • Patent number: 8982774
    Abstract: A network based positioning (NBP) system is disclosed that allows any of its access points (APs) to initiate ranging operations with a station device (STA), regardless of whether the STA is in power save mode and regardless of whether a particular AP is currently associated with the STA. For example, to initiate ranging operations with the STA from a non-associated AP, the non-associated AP obtains the TSF timer of the associated AP, and then uses the obtained TSF timer to derive the associated AP's beacon transmission schedule and thereby determine when the STA's corresponding wake-up periods occur. Thereafter, the non-associated AP can initiate ranging operations with the STA during the STA wake-up periods, thereby ensuring that probes sent from the non-associated AP will arrive at the STA while the STA is awake from power save mode.

  • Patent number: 8982782
    Abstract: While a first entity and a second entity are engaging in a communication session on multiple wireless links, the first entity may adjust the power level at which to send power control commands (PCCs) directed to the second entity based on a respective channel quality at which each wireless link is carrying the communication session. For example, the first entity may identify which wireless link is carrying the communication session at a best channel quality and then cause an increase of a transmission power at which to send PCCs directed to the second entity on the identified wireless link. As another example, the first entity may determine that a respective channel quality of each wireless link satisfies a given condition and then cause an adjustment of a respective transmission power at which to send PCCs directed to the second entity on each wireless link.
