  • Patent number: 10321390
    Abstract: An antenna system with network awareness includes a control system that points the antenna to a compatible network. The user provides the antenna with an input of a particular wireless service carrier and the control system begins searching for radio frequency signals that indicate the antenna is pointed at a compatible tower. Once a tower is located, the control system reads the carrier identification data transmitted from that tower to determine if the wireless carrier is compatible with the user's service. If an appropriate signal is not found, the control system will continue moving the antenna until another tower is found and the carrier identification information will again be checked. This process is repeated until a compatible tower is identified. Additional iterations can locate additional compatible towers. The antenna can be moved to a final position where the desired network signal is at the highest detected RF power.

A scheduler schedules a channel to be available at the end of the latency period indicated in the allocation table. At the end of the latency period, the return message is received and the scheduler allocates a channel as defined in the allocation table. The scheduled channel is used to transmit the message to or from the corresponding subscriber.

  • Patent number: 8973060
    Abstract: There is provided a method where a terminal amplifies an MBS signal that the terminal receives using a terminal in an MBS service, transmits the amplified signal to another terminal and controls it in order to overcome the fact it is not possible to provide high quality contents over a broad area due to interference signals between MBS zones, a terminal is used as a repeater at MBS transmission time only, and an output of a repeating signal of the terminal is controlled so that an excessive interference signal for another MBS area is not generated when the terminal operates as a repeater.

  • Patent number: 8937874
    Abstract: A method of controlling gains within a repeater may include determining a power control set point value which controls a transmit power of a mobile station (MS), and receiving a downlink signal from a base station transceiver system (BTS). The method may further include measuring a power of the received downlink signal, and computing a power level of a signal expected at the uplink of the repeater, wherein the computing is based on the measured downlink power and the power control set point value. Finally, the method may further include adjusting a gain of at least one amplifier based on the computed power level. An apparatus for controlling gains in a repeater may include a baseband processor for performing the above method.

  • Publication number: 20150011157
    Abstract: A multi-amplifier system includes a remote amplifier located near one or both system antennas. Locating the remote amplifier closer to the antenna improves the system performance while meeting regulatory limitations. The base unit may also have multiple remote antenna ports on one or both sides of the base unit allowing multiple remote antennas to be connected on that side of the base unit. A signal splitter with multiple antenna ports allows multiple remote antennas to be connected on the same side of the base unit. A remote amplifier located near each remote antenna removes the associated signal propagation losses from the regulated system performance. The base unit includes an amplifier detector for each remote antenna port to determine which output ports are connected to remote amplifiers. An automatic gain adjustment unit maintains the system gain, typically at the regulatory gain limit, based on the detected system configuration.

  • Patent number: 8885742
    Abstract: An apparatus and method for transmitting and receiving a demodulation reference signal (DM RS) are disclosed. A method for controlling a base station (BS) to transmit a demodulation reference signal (Demodulation RS or DM RS) in a wireless communication system includes transmitting, by the base station (BS), a DM RS for a relay node (RN) to the relay node (RN) through a specific backhaul subframe to which an extended cyclic prefix (CP) is applied. The DM RS is transmitted over two resource elements (REs) of individual subcarriers having subcarrier frequency indexes 2, 5, 8 and 11 in a frequency axis within a second slot of the specific backhaul subframe.

The destination station may select at least one signal to process from among the direct and relay signals based on the metrics for the source and relay stations. The destination station may select the direct signal if the metric for the source station exceeds a threshold. The destination station may select the relay signal from each relay station having a metric exceeding at least one threshold. The destination station may process the at least one selected signal to recover a transmission sent by the source station to the destination station.
