  • Patent number: 11412569
    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.

  • Patent number: 11337191
    Abstract: A serving base station allocates communication resources to be used by an aerial vehicle user equipment device (AV-UE) for uplink data transmissions. A neighboring base station is informed, via an air interface, of the communication resources that were allocated to the AV-UE. In some examples, the AV-UE retransmits scheduling assignment information, received from the serving base station, to the neighboring base station. In still other examples, the AV-UE transmits a sounding reference signal (SRS) to the neighboring base station. The neighboring base station can decode the retransmitted scheduling assignment information and/or the SRS to obtain information regarding the communication resources that have been allocated to the AV-UE for uplink data transmissions. The neighboring base station mitigates interference from the uplink data transmissions sent by the AV-UE.

  • Patent number: 11297569
    Abstract: Methods, systems, and devices for wireless communications are described. Some systems support user equipment (UEs) achieving power savings by operating in a connected discontinuous reception (C-DRX) mode. The systems may additionally utilize wakeup signals for further power savings at a UE. For example, a UE may be configured with a wakeup signal resource configuration (e.g., a first search space configuration) for monitoring for wakeup signals while operating in a low power mode. This first search space configuration may be different from a second search space configuration for the UE operating in an active mode. When in a low power mode, the UE may monitor for wakeup signals according to the wakeup signal resource configuration. If the UE receives a wakeup signal in a wakeup signal resource defined by the configuration, the UE may initiate a wakeup procedure and transition to the active mode for data communication.
