  • Publication number: 20200403658
    Abstract: To employ beamforming to increase signaling distances, one wireless device trains a beamformer using a signal being received from another wireless device. The trained beamformer can then communicate with the other device via a signal beam until channel conditions change. In example implementations, a base station (BS) (104) reserves an air interface resource unit (322) for beamformer training in conjunction with allocating a resource unit (321) for downlink data (706). The BS transmits a downlink control channel communication (602) to a user equipment (UE) (102) with a downlink data grant (702) indicative of the allocated unit. During the reserved unit, the UE transmits an uplink tracking communication (604), which can include a pilot signal, to the BS for beamform training. The BS then uses the freshly trained beamformer to transmit the downlink data as a downlink data channel communication (606) via a downlink beam (526) during the allocated unit.

  • Patent number: 10868654
    Abstract: Techniques and apparatuses are described that enable customized transmission of a system information message. One or more transmission characteristics of the system information message are tailored for a particular user equipment (UE) device or a group of UE devices. In one aspect, a response frequency used to transmit the system information message is customized based on a requested frequency of the UE device. In another aspect, a beamform pattern used to transmit the system information message is customized based on an angle to the UE device. In general, these customizations increase an amplitude of the system information message at the UE device, which increases an effective range of the system information message and enables a larger quantity of UE devices to establish communication with a base station. The customization also enables the base station to efficiently transmit the system information message to one or more UE devices.

  • Publication number: 20200351791
    Abstract: This document describes methods, devices, systems, and means for a low-power connected mode for wireless communication systems. In aspects, a user equipment (110) detects a thermal state or a battery state-of-charge while operating in a Radio Resource Control (RRC) connected mode (302). Based on the thermal state or the battery state-of-charge, the user equipment (110) transmits a request message to a base station (120) to request to enter into a low-power connected mode (304). The user equipment (110) receives a configuration message from the base station (120) to activate the low-power connected mode (306). The user equipment (110) then activates the low-power connected mode (308). Activating the low-power connected mode enables the user equipment (110) to reduce the thermal state and power consumption by maintaining an RRC connection with reduced functionalities, such as without monitoring a downlink channel for downlink signals from the base station (120).

  • Publication number: 20200322805
    Abstract: This document describes techniques and apparatuses for base station location authentication. In particular, a base-station-location server 264 provides protection against a Global Navigation Satellite System (GNSS) spoofing attack or a cellular-network spoofing attack by auditing processed locations 504 of base stations 120 within a cellular network. The base-station-location server 264 maintains a list of authenticated base stations, generates a security key 321 for a base station 120 that is authenticated, and sends the security key 321 to the base station 120 in an authentication message 522. The authenticated base station 120 uses the security key 321 to generate an encrypted positioning reference signal that protects timing information and/or a location 504 of the base station 120. The encrypted positioning reference signal also enables a user equipment (UE) to determine that the base station 120 is authenticated by the base-station-location server 264.

  • Publication number: 20200322962
    Abstract: Techniques and apparatuses are described for enabling user equipment to coordinate for interference cancelation. In some aspects, base stations form a user equipment coordination set by pairing a UE of a base station with another UE of another base station. The UE receives, from the other UE, information regarding an uplink transmission of the other UE to the other base station, the information including I/Q samples for the uplink transmission. Based on the received information, the UE can model interference from the uplink transmission of the other UE to a reception of a downlink transmission by the base station to the UE. After the UE receives the downlink transmission, the UE cancels, based on the modeling of the interference, the interference to the received downlink transmission from the uplink transmission of the other UE. By so doing, receiver performance or link quality of the interference-canceling UE can be improved.

  • Publication number: 20200275424
    Abstract: The present disclosure describes methods and apparatuses for beamforming for communication over preferred resources of a wireless network. A user device receives a signal from a plurality of antenna arrays of one or more base stations. The signal is transmitted, by the base stations, over a set of dedicated communication resources of a wireless network. Each of the base stations may dedicate a same set of resource elements for narrow-band communication with user devices outside of a standard range of a single antenna array. The user device determines a quality of the signal received over the dedicated communication resources and generates an index to identify preferred resources for communicating with the one or more base stations. The user device then communicates the index to the base stations to enable the base stations to establish a narrow-band wireless connection with the user device.
