  • Patent number: 10314037
    Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

  • Patent number: 10244532
    Abstract: Techniques for communicating channel data regarding a channel plan are described herein. For example, a device may communicate a channel information element that includes a tag indicating a first operating context to which to apply channel data regarding a channel plan. The channel information element may also include a reference tag to indicate whether the channel data is contained in the channel information element or has been previously received and/or to identify a second operating context associated with previously received channel data. If the reference tag indicates that the channel data is contained in the channel information element, the channel data may be extracted from the channel information element and applied to the first operating context. If the reference tag indicates that the channel data has been previously received, the previously received channel data may be accessed and applied to the first operating context.

  • Patent number: 10244470
    Abstract: The present description provides methods, computer program products, and systems for saving power in Wi-Fi devices utilizing Bluetooth. A Wi-Fi radio transitions to deep sleep mode from active mode while a Bluetooth radio remains active. An active Wi-Fi connection to the access point can be maintained by the station while in deep sleep mode as needed to prevent being disassociated. Responsive to the indication of data packets waiting at the access point, sent over the Bluetooth radio, the Wi-Fi radio at the station can be transitioned from the deep sleep mode to the active mode. A notification of active mode is sent to the access point currently associated with the Wi-Fi radio so that packets can be forwarded.
