  • Publication number: 20190246301
    Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, wireless devices (e.g., user equipment (UEs) and base stations) may communicate using beamformed transmissions. If a wireless device receives a transmission over multiple receive beams, the device may utilize signal measurements over the beams to determine a signal direction, a type of noise associated with the transmission, or both. The device may determine a signal direction based on received signal strength measurements over at least two receive beams and may select a beam for communication based on the determined signal direction. Additionally or alternatively, the device may compare noise measurements for the signal over at least two receive beams and may determine whether the noise corresponds to interference or white noise. The device may detect the direction of an interferer and may modify reception or demodulation based on the type of noise detected.

  • Patent number: 10374679
    Abstract: Methods, systems, and devices for wireless communication are described that support overriding a beam monitoring pattern for control channel transmissions based on channel conditions between a user equipment and a base station. A base station may select a beam monitoring pattern for transmitting control channel transmissions, which may include a pattern in which two or more beams are used for control channel transmissions. In the event that a first beam of the beams used in the beam monitoring pattern meets certain metrics, the use of one or more additional beams according to the beam monitoring pattern may be overridden and transmissions continued using the first beam. The metrics for continuing use of the first beam may include channel quality metrics, a number of consecutive successful transmissions using the first beam, one or more other metrics, or any combination thereof.
