  • Patent number: 10791469
    Abstract: The present invention is designed to expand the coverage of reference signals in small cells that are arranged to overlap a macro cell, and, furthermore, reduce the interference between the small cells and improve the received quality of the reference signals in user terminals. The radio communication method of the present invention provides a radio communication method in a radio base station forming a small cell that is placed to overlap a macro cell, and includes the steps of generating a reference signal for measuring received quality, in a first transmission period in which beamforming is not executed, transmitting the reference signal in a narrower transmission bandwidth and with greater transmission power than in a second transmission period in which beamforming is executed, and allocating the reference signal to a band associated with information that is specific to each radio base station forming a small cell, and transmitting the reference signal.

    Abstract: Methods, systems, and devices for wireless communication are described that provide for establishment of communication links between nodes in a wireless network, in which an access node (e.g., a node that provides access to a core network) may provide a communication link configuration and resources for communications between multiple nodes. In some cases, an access node may receive a request from a first node to establish a communication link with a second node. The communication link may be, for example, a directional transmission beam that carries data or control information, or a combination thereof, between the first node and the second node. The access node may determine the communication link configuration based on one or more link measurements provided by the first node or second node, and provide the configuration information to one or both of the first node or the second node.

  • Patent number: 10490889
    Abstract: Methods and systems for improving communication using angle dithering are presented. Embodiments of the present invention provide increased throughput and robustness after link establishment by providing fast fading characteristics in environments dominated by slow fading. In particular, fast fading characteristics are induced by steering the transmitter and receiver antennas in optical and beyond line-of-sight troposcatter communication systems based on dither patterns. In non-line-of-sight (NLOS) communication systems, using coordinated dither patterns at the transmitter and receiver ensures that successive common scattering volumes become decorrelated, whereas in line-of-sight optical communication systems, the dither pattern is based on the tropospheric scintillation in free space traversed by the established link.

  • Patent number: 10425901
    Abstract: A transmit beamforming gain and a receive beamforming gain may be used when adjusting an uplink transmit power. For example, a user equipment (UE) may receive downlink communications from a base station on a receive beam having a beamforming gain that is different from a beamforming gain for an uplink transmit beam. The UE may adjust an uplink transmit power (e.g., for transmitting a random access channel (RACH)) based on a difference in the beamforming gains. For example, a parameter representing the difference in the beamforming gains, in addition to a maximum allowed transmit power, a target preamble received power, and an estimated path loss, may be used when determining an adjusted uplink transmit power for a RACH transmission. The adjustment may result in a higher or lower transmit power depending on the difference in the receive beamforming gain and the transmit beamforming gain.

In an alternative implementation, the repeater will select an optimum antenna configuration at start-up. Once the configuration is selected, the system will keep this configuration until the performance metrics for this configuration drops below a specified level. At this point, the system will start scanning antenna configurations to find a new configuration that yields a performance better than the required minimum performance level.

  • Patent number: 10122555
    Abstract: Cross-phase interference occurs in dual polarized or orthogonal polarized microwave links when independent local oscillators (LOs) are utilized in each outdoor unit (ODU) transceiver operating on the same frequency channel. If the cross-phase noise is not compensated the performance of the microwave link will be degraded. In order to reduce cross-phase noise two or more pilot symbols are utilized to enable cross-phase noise estimates to be determined at the receiver of the microwave link. The pilot symbols enable a cross-phase noise compensation factor to be determined for the signal from the one or more cross-phase noise estimates. The received signal can then be compensated using the estimated cross-phase noise compensation factor.
