  • Patent number: 10993274
    Abstract: In some implementations a system can be configured to reduce the burden of pairing user devices with playback devices. For example, all users (or user devices) who commonly operate within a particular environment (e.g., a home) can be configured as authorized users of playback devices within the particular environment. When one of the authorized users pairs a user device with a playback device, all of the user devices for all authorized users can be automatically paired with the playback device as a result of the single pairing. Thus, only a single authorized user is burdened with the pairing process in order to pair all authorized users with the playback device.

  • Patent number: 10966213
    Abstract: A first access node that is operating on a first TDD carrier having a first TDD configuration will determine that a second TDD carrier on which a proximate second access node is operating has a different, second TDD configuration, such that there is at least one time interval in which the first TDD carrier is downlink concurrently with the second TDD carrier being uplink. In response to at least this determination, the first access node will then transition to a mode in which, during the time interval, the first access node will operate with reduced transmission power on a frequency portion of the first TDD carrier that is closest in frequency to the second TDD carrier. Further, the first access node could allocate the lower-transmission-power frequency portion for use in transmission to served devices deemed to be in at least predefined threshold high quality coverage of the first access node.

  • Patent number: 10924415
    Abstract: Embodiments provide techniques for device-level traffic shaping in a communications network. Embodiments operate in communication networks providing connectivity to large numbers of user-side network nodes via shared communications links. For example, customer premises equipment (CPE) devices behind one of the user-side network nodes are classified into device types according to a predetermined rate-relevant characteristic of the CPE device. Upon receiving a forward-link (FL) traffic flow destined for one of the CPE devices, the device type of the CPE device is identified, and the FL traffic flow is shaped in accordance with a traffic shaping policy that corresponds to CPE device type. Various embodiments are tailored to support architectures having device-level shapers and/or network address translators (NAT) in user-side network nodes and/or in a provider-side network node.
